    Device for irrigation of roadways
    The invention relates to a device for irrigation of roadways with at least one embedded in the roadway, a liquid inlet opening and at least one liquid outlet opening having nozzle in a
    Holder is releasably secured, wherein the nozzle has an adjusting device for influencing the at least one liquid outlet leaving the water jet.
    Roadway irrigation will be on both test tracks
    Automotive companies as well as on terrain needed, on which the driving safety is to be trained. It is well known that vehicles and vehicle tires behave differently on wet roads than on dry roads. In order not to have to make the corresponding driving behavior or driving safety training dependent on the current weather conditions, it is necessary to temporarily wet the roads with water, wherein it is desirable that the respective test situation adapted amounts of water are given to the road. In order to create a controllable wetting of a road surface, it is recommended to let the nozzles into the road. However, this has the disadvantage that, in contrast to Wassersprinklereinrichtungen on the roadside irrigation devices of cars and trucks are run over, which places high demands on the mounting stability. In part, such irrigation devices are not only overrun by tires; In many cases blocked wheels also slide over such devices, which entails the risk that the above sharp-edged parts may cause undesired tire damage.
    In order to ensure a safe and non-destructive override, a device with a nozzle is proposed in WO 2004/088043 A1, which is detachably fastened in a holder and designed as a sprinkler nozzle which can be moved over by persons and / or trucks. The nozzle has a plurality of star-shaped outlet channels, which are covered by a baffle body from above, which is formed as the head of a screw the nozzle body screw. The nozzle is arranged in alignment with the road surface.
    EP 2 843 132 A2 describes a sprinkler for irrigating a roadway, which is a substantially high and rigidly connectable to a substrate
    Base element with a connection for a pipeline as well as one over the
    Base member hydraulically connected to the terminal nozzle, wherein the nozzle, a height adjustment is releasably connected, which connects the base member and the nozzle along a longitudinal axis of the base member movable. The
    Adjustability should be ensured in particular by means of a thread.
    Furthermore, the outlet opening of the nozzle should at least partially by a
    Recess of a movable, preferably rotatable about a longitudinal axis, are arranged in the nozzle arranged spray insert. With the nozzle body, a diaphragm can be connected, through which the inlet opening is at least partially closed. By means of the height adjustment, the adjustable throw of the sprinkler system should be ensured. The nozzle used has a plurality of inlet openings, which are partially closed by a rotatably connected to a nozzle body diaphragm to regulate the amount of water. This should be possible by an aperture screw which is rotatably connected to the nozzle body. At the upper end of the nozzle a fixing screw is provided, which fixes a spray insert on the nozzle body, with its recesses
    Forms outlet openings which define the spray characteristic of the nozzle.
    Although the configuration described in EP 2 843 132 A2 permits regulation of the water supply to the nozzle, the entire sprinkler body must be completely unscrewed from the base element in order to adjust the aperture. Only then can you adjust the aperture and screw the sprinkler back in completely and put the system back under pressure. Only now is it recognizable, which change of the spray jet was adjusted. This adjustment changes the throwing distance as well as the amount of water (both are interdependent).
    It is an object of the present invention to improve the above-mentioned device in that different throw distances of the various
    Fluid outlet are easily adjustable.
    This object is achieved by the device according to claim 1, which is characterized in that the adjusting device for influencing the water jet leaving the at least one fluid opening is a throttle element which partially closes the passage cross-section of at least one fluid opening and in that the actuating device from the outside in the installed state of the nozzle That is, without the removal of the nozzle (the sprinkler), is adjustable.
    This particularly takes account of the fact that in
    Driving safety centers or on test tracks always a larger number of
    Sprinklers are supplied simultaneously by a single pump with water. In the respective route systems, there is often a natural gradient, which
    Depending on the sprinkler position, deviations in the water pressure at the sprinkler lead to different throwing distances of the water jet, whereby one over the
    Slope of the roadway different wetting area arises. Without the inventive design, pressure differences seriously affect because the input pressure is on average at about 1.5 bar, so that differences in height of one or even several meters already result in significantly different casting distances. An adjustable throttle allows for easy
    To compensate for these differences and thus adjust all existing sprinklers with the same throw distance, so that a uniform wetting of the route is achievable. Even with flat surfaces with constant inlet pressures for all sprinklers, the throttle adjustment can be adjusted individually for each sprinkler according to the pump performance and the individual wishes, and the water volume and thus a precisely defined wetted surface.
    Preferably, the throttle element is infinitely adjustable, so that even sensitive
    Regulations are possible. These adjustments of the throttle element are possible from the outside when installed.
    In a specific embodiment of the invention, the throttle element consists of a disc mounted in the nozzle, which is rotatable or pivotable about a surface normal axis as an axis and allows a continuous partial closing.
    Preferably, an embodiment can be selected in which only a single
    Disk is used as a throttle element, which has a plurality of openings.
    By rotating this disk, different outlet cross sections for different nozzle openings can be selected depending on the selected overlap cross section with the liquid outlet openings of the nozzle. When using a single disc can thus simultaneously the passage cross sections of several
    Change the liquid outlet openings.
    For reasons of symmetry, the nozzle has a plurality of liquid openings, each with the same passage cross-section, of which at least two partially through the
    Throttle element are closable.
    For simplified handling, the disc is a further development of
    Invention via a pinion adjustable, which engages in a toothed segment profile of the disc. Preferably, the pinion consists of a sheet metal profile, which on a
    Adjusting screw is mounted, which is further preferably operable from the outside.
    If the disc has abutment surfaces on both sides of the toothed segment profile, by which the angle of rotation of the disc is limited, it can also be ensured that incorrect settings such as, for example, the complete closure of all
    Outlet openings are avoided.
    In practice, it has been proven that the disc has at least one, preferably a plurality of passage openings which are each smaller than the respective cross-sectional areas of the fluid outlet openings. The maximum flow through an outlet opening is thus determined by the passage opening of the disc, provided that the openings are aligned one above the other.
    As an alternative to the above-outlined embodiment, a means of a
    Adjusting screw with respect to a nozzle body height adjustable
    Cylinder body used as a throttle element, which has raised profiles on its side facing the nozzle base body, which partially closes the cross section of the liquid inlet opening or inlet openings depending on the altitude. Preferably, the set screw is fixed in the nozzle main body, wherein upon rotation of the screw, the cylinder body can be raised and lowered forcibly guided over two dowel screws. In a specific embodiment, raised profiles may be used, which are conical or frusto-conical elevations, which are each arranged opposite the liquid inlet openings and release depending on the height setting different sized annular gaps with different widths to the liquid passage. Unlike in the first embodiment, instead of a rotating disk, a cylinder body which can be raised and lowered relative to a main body of the nozzle is used, which regulates the liquid flow via the profiled design of the side facing the nozzle body and the inlet openings. When using conical or truncated cone shapes, which are circular in cross-section
    Inlet openings are moved, resulting annular passageways, wherein the ring width depends on the distance at which the truncated cone dips into the corresponding liquid inlet bore. If it comes to contact of the truncated cone with the jacket of the liquid inlet, the liquid inlet is closed. This embodiment allows extremely sensitive control of the amount of liquid that is allowed to pass through the nozzle outlet.
    In particular, the nozzle is designed as a sprinkler nozzle, in which the
    Outlet openings are covered up by a baffle body, which is preferably releasably secured by a screw. Such baffles are in the
    Principle known in the art and ensure that the effluent amount of water causes uniform roadway wetting.
    The nozzle itself preferably has a star shape
    Flüssigkeitsauslassöffnungen, in particular over a horizontal
    Spray angle between 90 ° to 180 ° extend. The star-shaped profile of the nozzle outlet used can ideally be designed as a semicircular profile of a separate body, which can optionally be used so that the outlet channels are either released over the entire 180 ° or only partially covered or released up to 90 °. In this way you can have different
    Adjust spray segments of the outflowing water.
    In order to maintain the functionality of the nozzles even in winter operation, the nozzle is equipped with a switchable heating.
    Embodiment are shown in the drawings. Show it
    1-3 each show different views of sprinkler nozzles as known from the prior art,
    Fig. 4-7 respectively different sprinkler nozzles according to the present
    Invention in a first embodiment,
    8 is a plan view of the sprinkler nozzle of FIG. 4-7,
    9-11 different views of a second embodiment of the sprinkler nozzle according to the invention and
    Fig. 12 is a plan view of this nozzle.
    The known from the prior art sprinkler nozzle consists of a
    Round body, which is designed as a screw-threaded part. This base body 1 has four cylindrical holes B and a fitting hole E, which is closed with a locking screw S. In the upper area of the
    Base 1, that is at its largest diameter, is an annular
    Seal 4 provided. Central is a baffle body 2, which is designed as a threaded screw, fixed in the body. This baffle has on his
    Bottom, that is the body facing the ring side water
    Exit grooves in a star-shaped orientation, which are shown as arrows in Fig. 3 and extend in the selected embodiment over a spray range of 150 °. If necessary, one or more of the holes can go through
    Closing plug are blocked. In the configuration selected in FIG. 3, these would be the holes shown on the left in FIG.
    The fitting bore E and the further threaded bores K in the main body (see FIG. 1) can be used to convert the conventional sprinkler nozzle according to FIGS. 1-3 into a nozzle according to the invention. The disadvantage of the sprinkler nozzle after
    Namely, Fig. 1-3 consists in that the spray characteristic can not be influenced and that by rotating the spray body by means of a special key via two each introduced at the outer edge holes only the direction of the predetermined spray jets is variable.
    In the sprinkler nozzle according to FIGS. 4-7, the closure screw S (see FIG. 2) is replaced by the fitting screw 12, which is sealed with a seal 13 on the base body. The dowel screw 12 is provided with a nut 15 (see
    Exploded view in Fig. 7) fixed to the base body 11 by means of a technical adhesive. Further, the nozzle has a pinion 16 which is rotatably mounted relative to the nut 15. The pinion 15a is in turn fixed by means of a technical adhesive, so that upon rotation of the dowel screw 12, the pinion 16 can be rotated.
    As can be seen from FIGS. 4 and 6, the pinion 16 engages in the sector gear 17a of a
    Disc 17, so that upon rotation of the dowel screw 12, the disc 17 is pivotable over a limited angular range. Figs. 4 and 6 show, respectively
    End positions of the pivotable disc 17, which can be adjusted via the pinion 16.
    In the embodiment shown in Fig. 4 and 6, the holes shown in the left respective drawing half, which as
    Serve fluid passage, closed.
    The disk 17 has, as can be seen from FIGS. 4 and 6, pear-shaped openings 17 b. From Fig. 4 it can be seen that the two unsealed holes B1 and B2 serve as a liquid passage. Depending on
    Position of the disc 17 in the end positions shown in FIG. 4 or FIG. 6, the water in the nozzle body with high pressure of 1.5 bar (1.5 x 105 Pa) through the full cross-section 17 b, shown in Fig. 4 hatched is, flow through. If the bores B1 and B2 are closed by rotation of the disk 17 into the end position according to FIG. 6, the smallest possible throttle gap 20 results as the overlapping area of the bores B1 or B2 with the
    Opening 17b of the disk 17. The screw 18 is screwed and fixed in the base body 11 except for the mechanical stop M (see FIG. 5) by means of a technical adhesive. The throttle disk 17, to which the screw 18 defines a gap s between the screw 18 and the throttle disk 17, is rotatable about the pinion 16 but still fixed below the nozzle body 11. The diameter of the
    Round ring 19 is chosen so that it bridges the gap s and the
    Thrust washer 17 presses with defined force to the body. As already mentioned and indicated in Fig. 7, closure body serve V1 and V2 for
    Closing the two holes A1 / A2 shown in the left half of FIG. 4 or FIG. 6. The incoming liquid flow can only flow via the two right-hand openings 17b in the throttle disk 17 to the star-shaped outlet channels in the main body 11, that is to say in the direction of the arrows shown in FIG. 8. The position of the throttle openings 17 b is changed by means of Allen key on the rotation of the dowel screw 12 and thus the rotation of the pinion 16 and the throttle plate 17. Starting from FIG. 4, the open cross-section of the overlapping bores 17b and 16b is reduced
    Bores B1 and B2 by rotation of the dowel screw of the pinion 16 in
    Clockwise. The throttle effect is continuously stronger until the position of FIG. 6 is reached. In order to reduce the throttle effect, that is to increase the open common cross-section of the openings 17b and the holes B1 and B2, the dowel screw 12 and thus the pinion 16 must be rotated counterclockwise. Respective mechanical stops prevent overwinding. In the selected embodiment, a minimum throttle gap S2 of about 1.8 mm is achieved with the stop at the smallest throttle opening, which ensures that contamination of the throttle by grass or sand is effectively prevented.
    In the embodiment shown in FIGS. 9-12, the
    Closing screw S replaced by the adjusting screw 22. Instead of the disc 17, a cylinder body 26 is used, which has on its side facing the nozzle body 4 conical projections 27 whose largest cone diameter is as large as the diameter of the existing four holes B. Der
    Cylinder body 26 is mounted to the nozzle body 21 by means of two fitting screws 23 and 23a (from below). The adjusting screw 22 is fixed by means of a nut 25 and a lock nut 25a on the base body 21 with a defined game.
    Preferably, the fixation also takes place here by means of a technical adhesive. The
    Adjusting screw 22 engages with its free end in a thread of the cylinder body, so that by rotation of the adjusting screw 22 of the cylinder body 26 can be raised or lowered relative to the main body 21. When approaching the cylinder body 26 to the base body 21, the conical projections 27 are inserted into the holes B, whereby initially four adjacent annular spaces are formed, through which the water flows into the holes B. The closer the cylinder body is guided to the main body 21, the narrower the free annular gap becomes. As adjusting means is the adjusting screw 22, which has a
    Allen key can be operated. The two fitting screws 23, 23a serve as positive guides for the cylinder body. Again, stops are provided which prevent mechanical over-rotation. The advantage of this second
    Variant is that a very sensitive adjustment of the annular throttle gap is possible.
