    The invention relates to a hydro-dynamic ram with at least one mounted in a bearing frame impeller having a hub and attached thereto, projecting from her blades, the impeller in operation brings about a water level difference between its upstream side and its downstream side.
    Such a dynamic pressure machine is known from AT 404 973 B and from AT 501 575 A1. In such a dynamic pressure machine, the impeller is mounted in a flume such that the hub of the impeller can impinge the water in the flume, so that a comparatively high head level upstream of the impeller and downstream a lower subsea level in operation are obtained. The blades attached to the hub form pockets for transporting the water, wherein in operation the water pressure causes a torque about the axis of the impeller, the axis of the cylindrical hub. According to AT 404 973 B, the wheels are stored in stationary racks. In the AT 501 57 5 Al is also proposed to store the respective impeller in a vertical section U-shaped frame, which is formed from vertical side plates and a side plate connecting these bottom plate. This plate frame can also be inserted with the help of guides in concrete pillars, so as to enable a quick start-up of the dynamic pressure machine. However, the frame formed of plates and bearing the impeller is relatively expensive and heavy, so that the cost thereof is relatively high, and moreover an adaptation of the dynamic pressure machine to different size ratios, e.g. Widths of the channel, comparatively tedious.
    These structural problems and in particular the high manufacturing costs have so far brought with it that the known dynamic pressure machines were hardly realized practically for lack of economic efficiency.
    It is an object of the invention to provide a hydro-dynamic ram printing machine as stated above, which has an improved design, on the one hand, a high flexibility or customization and on the other hand, low production costs, * * * * ft * * * · «·» «· m • * 4 * • 2 ** · · * * * * so that the operation of such dynamic printing machines is economically possible.
    To solve this problem, the invention provides a hydropower racking machine as defined in claim 1. Advantageous embodiments and further developments are specified in the subclaims.
    In the present dynamic pressure machine thus a forming tube design with four forming tubes or generally supports for the bearing frame of the impeller is provided, wherein the four supports, two vertical support, an upper support and a lower support are constructed in a rectangular shape around the impeller. The two vertical, lateral supports or forming tubes also carry the wheel bearings for the impeller. On one of the vertical supports is further preferably the drive unit (gear unit) and an electric motor-generator machine attached to convert the kinetic energy of the impeller into electrical energy.
    If appropriate, the bearing frame can be subdivided by at least one further, central, vertical carrier, preferably likewise a shaped tube part, in order to support at least two impellers axially adjacent to one another in the bearing frame.
    To achieve the simplest possible sealing of the rotor, i. Impeller, it is also advantageous if the impeller is completed at its axial end by rotating it with shields. The aforementioned cover plates allow in consequence a particularly simple seal, as preferably on the vertical supports of the bearing frame sealing elements, which rest against the cover plates, are mounted to seal the respective impeller. The sealing elements are in particular formed by sheets which are fastened to the vertical supports and extend substantially over the storage height, preferably from the lower horizontal support to the level of the upper side of the hub or somewhat beyond, and the sealing lips which are elastic as actual sealing elements , eg made of plastic material or even of sheet metal, wear.
    As supports for the bearing frame, besides form tubes, other carrier forms, such as e.g. T-strap, in stretcher.
    In order to direct the water tangentially from an upper-side inlet area around the impeller to a lower-side outlet area and, moreover, to seal the impeller at the wheel periphery, it is favorable if on the upstream side on the vertical supports of the bearing frame a curved cropping plate, e.g. via cantilevered holders, the curvature of which is matched to the path of the radially outer ends of the blades as the impeller rotates.
    As mentioned, the present bearing frame design, especially in the case of the forming tubes, allows a very flexible, simple modular concept, allowing for easy adaptation to the most favorable wheel width, for adjusting the absorption capacity of the dynamic pressure machine at the same damming height. In this case, as already mentioned, a plurality of wheels in a common bearing frame, which is divided by vertical support, stored and mounted as a unit. The bearing frame is preferably arranged in each case in a stationary frame, which is likewise designed like a frame, wherein such frames together with the bearing frame and wheels are next to each other arbitrarily cascaded.
    Preferably, further, the respective bearing frame is arranged vertically raised and lowered relative to the stationary frame by means of a lifting device. As a result, for example, for maintenance purposes or in a fault, the actual machine, so the unit consisting of bearing frame and impeller, are lifted out of the water. The lifting device can preferably with a rack drive, optionally in conjunction with a Nothandbetrieb, with crank, as is known in itself about locks are formed, but also with a threaded spindle drive or in particular with hydraulic working cylinders.
    In order to make the vertical movement of the bearing frame relative to the frame with as little friction as possible, it is further advantageous if the bearing frame on its vertical supports laterally outside guide elements, such as rollers or sliding pads, for low-friction guidance on corresponding guide surfaces of the stationary frame.
    The present design principle brings a significant simplification in the construction and assembly of the dynamic pressure machines and further savings in weight and cost with it, so that the economics of dynamic machines is significantly increased. In the case of the attachment of several wheels in a storage frame or a cascading depending on the water level, the side by side impellers or dynamic machines put into operation (if correspondingly high amounts of water are given} or occasionally locked (at low water volumes) in the manner of sliders up and down movable locking plates are used, which block a water supply locally.
    The invention will be explained below with reference to illustrated in the drawings, particularly preferred embodiments, to which, however, it should not be limited. In detail, in the drawing:
    Figure 1 is a perspective view of an impeller of a hydro-dynamic pressure machine, with laterally the impeller final shrouds. Figures 2 and 3 show such an impeller mounted in a rectangular support frame constructed of mold tube supports, namely from the underwater side (Figure 2) and from the upstream side (Figure 3); Figures 4 and 5, respectively Illustrating the flexibility of the present Formrohr-bearing frame two diagrammatic representations of ram pressure machines similar to FIG. 3 (ie from the upper water side), with the same height, but once with a relatively small axial dimension having impeller (Fig. 4) and the other with a 6 to 8 diagrammatically different dynamic pressure machines, now with lifting devices for vertical lifting or lowering of the bearing frame together with the impeller relative to a stationary machine frame, wherein in Fig. 6 schematically a drive FIG. 7 illustrates a rack and pinion drive associated with a unitary bearing frame supporting two wheels. FIG men, is shown, and in Figure 8 is shown a lifting system with an example hydraulic working cylinder. and
    9 shows a cascade-like arrangement of several dynamic pressure machines next to one another in a perspective view.
    In Fig. 1 is diagrammatically illustrated an impeller 1 for the present dynamic pressure machine, said impeller for storage in a bearing frame, as will be explained in more detail below, is intended. The impeller 1 according to FIG. 1 has a cylindrical hub 2 whose axis x-x is at the same time the axis of rotation of the impeller or rotor 1. At this hub 2 circular cover plates 3 are fixedly attached to the axial ends, which limit the width of the rotor or impeller 1. These cover plates 3, as will be explained in more detail below, allow an advantageous sealing of the impeller 1 in the bearing frame.
    At the periphery of the wheel hub 2 are further suitably shaped blades 4, e.g. welded to form bags for water transport, i. to absorb the water pressure and to cause a torque about the wheel axis x-x.
    The blades 4 of the impeller 1 may, in addition to the V-shaped arrangement shown, other arrangements, such as simple oblique arrangements {see, e.g. AT 404 973 B), and they may also have a curvature depending on the objective.
    In Fig. 2 is a hydro-dynamic machine 5 with such an impeller 1, as shown in Fig. 1, seen from the underside seen schematically illustrated. As can be seen, the impeller 1 is mounted in a generally rectangular shape bearing frame 6, which according to FIG. 2 (and FIG. 3) with two vertical supports 7, 8 and a lower support 9 and an upper support 10 around the Impeller 1 is formed around. The carriers 7 to 10 are preferably formed from rectangular cross-section shaped tubes, whereby a simple, lightweight, yet stable construction of the bearing frame 6 is achieved, which also allow easy adaptation to different dimensions, in particular widths of wheels 1.
    The vertical beams 7, 8 carry wheel bearings 11 (in Fig. 2, only one of these bearings is visible, the other is covered by a drive-generator unit 12), wherein the wheel bearings 11 are secured to cantilevered brackets 13, as shown Fig. 2 can be seen. This attachment of the bearing 11 is thus provided in the preferred embodiment on the downstream side (underwater side) of the dynamic pressure machine 5.
    The vertical supports 7, 8 are equipped on their outer sides, ie on the side facing away from the impeller 1, with guide roller units or the like, a friction-poor displacement of the bearing frame 6 in a stationary machine frame 16 (see FIGS. 4 and 5) Such an embodiment explained in more detail below with reference to FIGS. 6 to 8 with a lifting device for the bearing frame 6 in an advantageous manner.
    In Fig. 3, which, as mentioned, the upstream side or stromaufwär-term side of the ram 5 shows a further arranged in the lower region of the impeller 1, curved cropping sheet 17 is shown by means of attached to the vertical beams 7, 8, thereof cantilevered supports 18A, 18B is fixed to the bearing frame 6 and has a curvature adapted to the path of movement of the impeller 1 and the blades 4 of the same. With the aid of this bolster plate 17, the water can thus be introduced tangentially into the lower region around the impeller 1, so that it is on the underside (FIG. 2) on the underside of the impeller 1 in an outlet region 19 (FIG. 2) above the lower one Carrier 9 runs out and flows.
    Furthermore, it can be seen from FIG. 3 that sealing elements 20 are mounted on the upper side of the vertical supports or molding tubes 7, 8, each of which has a fastened to the support 7 or 8
    Sheet 21 and an attached sealing lip 22 have. These sealing lips 22 abut against the axially outer side of the respective circular cover plate 3 in a sealing manner. By this arrangement with the sealing elements 20 and further with the cropping plate 17 is achieved that the water of the channel is optimally utilized for the generation of electrical energy, i. the efficiency of the dynamic pressure machine 5 shown is thereby additionally improved.
    The unit 12 shown in Fig. 2 has in detail a gear 23, with which the rotational speed of the impeller 1 is converted into a higher rotational speed for the electric generator 24.
    The flexibility of the present bearing frame 6 according to the carrier or molding tubes used 7 to 10 results directly from a comparison of the perspective views of FIGS. 4 and 5: In Fig. 4 is a comparable to FIG. 3, relatively slim design of a dynamic printing machine fifth shown, in contrast to Fig. 5 by about 50% wider training of the dynamic pressure machine 5 is illustrated, which thus has a correspondingly increased absorption capacity at the same damming height. The illustrated form tube design of the bearing frame 6 thus allows an adaptation of the respective bearing frame 6 in the manner of a simple modular concept, wherein not only an adjustment in width, as shown in FIGS. 4 and 5, but of course also an adaptation to the diameter of Impeller 1, ie to the damming height, by using correspondingly longer, vertical support 7, 8 is possible. After determining the damming height, the capacity to swallow (ie the amount of water transported per time by the ram-pressure machine 5) again varies across the wheel width (see FIGS. 4 and 5).
    In addition, it can also be provided, for example, to accommodate two wheels in a bearing frame 6, as can be seen from FIG. 7, wherein the two wheels ΙΑ, 1B according to FIG. 7 are rotationally coupled to one another and a single drive-generator unit (cf. 2) in Fig. 2. The bearing frame 6 is divided by a central, additional vertical support 14, for example.
    In Fig. 7, further, for the " dual storage " 6, a lifting device 25 is shown, similarly as in FIGS. 6 and 8, lifting devices 25, namely by way of example of a different type, are illustrated.
    More specifically, as shown in FIG. 6, which again illustrates the upstream side of the ram pressure machine 5, on the stationary rack 16, i. on the upper sides of its vertical beams 26, 27, a yoke-shaped frame 28 with horizontal beam 31 attached to vertical supports 29, 30 on the upper side is shown. At the top of this beam 31 is a drive unit 32, for example with an unspecified electric motor and a stationary rotatably mounted spindle nut, the latter cooperating with a threaded spindle 33 which is fixedly fixed to the upper horizontal support 10 of the bearing frame 6. When the electric motor of the drive unit 32 is activated, when the spindle nut of the drive unit 32 rotates, the threaded spindle 33 is moved vertically upwards or downwards, depending on the direction of rotation, so that the bearing frame 6 is lifted or lowered vertically in a corresponding manner relative to the frame 16 of the dynamic printing machine 5.
    In this way, in the event of a malfunction or in the case of maintenance, the actual machine, i. the impeller 1 with the bearing frame 6 and the unit 12, lifted or lowered back into the water.
    Such a height adjustment can also be used to, for example, in the event of underwater backwater, such as flood, the impeller 1 with its frame 6 in a controlled manner to maintain the best possible distance of the wheel x-x relative to the underwater level. Such, provided for this purpose control device includes, for example, a level sensor for detecting the downstream underwater level, namely in relation to the height of the impeller 1 and the wheel axle xx, and an actual control unit, for example with a PLC unit, depending on the change in the height of the wheel axle xx relative to the underwater level to drive the drive unit 32 to a raising or lowering of the unit 6- 1. However, this is not illustrated here.
    In the embodiment of the lifting device 25 of FIG. 7, a rack and pinion drive is provided, wherein in the illustrated embodiment of Fig. 7 because of the greater width of the bearing frame 6 and thus the ram machine 5, an arrangement of two lateral racks 33 A, 33 B on the upper carrier 10 of Bearing frame 6 is provided. These fixedly connected to the bearing frame 6 racks 33A, 33B cooperate with not shown in detail gears in drive units 32A, 32B, these gears for the purpose of synchronization, for example via a shaft 34 can be rigidly coupled together. This also makes it possible to equip only one of the two drive units 32A, 32B with an electric motor which is not shown in greater detail in the drawings.
    It should be mentioned that, in particular in the case of a toothed rack drive, emergency manual operation with a hand crank (not shown) assigned to the drive unit 32 is also possible. In a similar manner, however, it is of course also possible to equip a lifting device 25 with spindle drive {see FIG. 6) with an emergency manual operation.
    According to Fig. 8, a further variant of a lifting device 25 is shown, namely with an example hydraulic working cylinder 35, which is at the upper beam 31 of the yoke 28, from this towering, attached, and the piston rod 36 passes through the spar 31 and fixed to the upper Support 10 of the bearing frame 6 of the impeller 1 of the dynamic pressure machine 5 is attached.
    Of course, instead of a hydraulic working cylinder and a pneumatic cylinder can be used.
    Furthermore, it is also conceivable to use a lifting device 25 with two (or more) working cylinders 35 (see Fig. 8) or with a plurality (eg two) lateral screw drives, as shown in FIG. 6 can be seen; On the other hand, in the case of simple arrangements as shown in FIGS. 6 and 8, a rack-and-pinion lifting device 25, as basically shown in FIG. 7, may also be provided.
    From Fig. 9 is finally still apparent that several systems or ram pressure machines 5, each with a stationary Ge vice 16 and an impeller 1 and, if necessary, several wheels ΙΑ, 1B (see also Fig. 7), can be arranged side by side in cascade form if there is a correspondingly wide channel; with such a cascade arrangement can be easily taken into account varying amounts of water in the channel, for example, in the case of ge wrestle amount of water in Fig. 9 shown on the right side ram 5, with the individual impeller 1, can be locked so for the other dynamic pressure machine 5, to operate with the wheels ΙΑ, 1B, in an optimal working area. The blocking of the individual dynamic pressure machines or wheels can be done with the help of not shown in the drawing on the upstream side locking plates, the development, for example, vertically from an upper rest position into a lower locking Stel, immediately before the respective impeller can be adjusted.
