    The invention relates to an arrangement of swimming platforms, in particular for plants for the production of solar energy.
    The importance of so-called alternative energy generation, especially of solar energy, is steadily increasing. Due to the relatively high space requirements of solar power plants, it is endeavored to relocate the same on water surfaces, especially on the oceans ("off-shore solar power plants"). To this end, various floating platforms have recently been developed to support the associated facilities. Due to the simple and lightweight construction with high load capacity platforms have recently been developed in particular, which are supported by an air cushion. To increase the efficiency of the solar power plants carried thereon, it is essential to align the platforms with the sun, i. to be able to track.
    Thus, both WO 2009/001225 A2 and the still unpublished Austrian patent application AT A 356/2010 describe preferably circular floating platforms with flexible covers, each defining a cavity, which can be pressurized by a compressor to provide the necessary buoyancy to create. The platforms are rotatable as a whole so as to be able to align them with the position of the sun. In preferred embodiments of WO 2009/001225 A2, rotation is effected by means of wheels in a ring surrounding the platform, for which purpose the platform floats in a circular basin got to. According to AT A 356/2010, engines with propellers are used to rotate the platform there.
    In no literature known to the inventors is it described how a composite of such platforms, i. several floating platforms, used for the use of solar energy and can be aligned with the sun, although it is often required due to the high space requirements of solar power plants to distribute the equipment required for the solar system on more than one swimming platform, in particular to equip multiple platforms with solar panels, and -1 - • ··! to swim in the sea. The aim of the invention was therefore the development of a corresponding system.
    DISCLOSURE OF THE INVENTION
    This object is achieved by the present invention by providing an array of floating platforms comprising: a) an anchored central platform; and b) one or more outer platforms each connected to the central platform via at least one connector, one or more of the platforms drive units mounted thereon are pivotable about a vertical axis, herein " rotate " rotation of a platform around its centroid and under " panning " a rotation around a boundary point is to be understood.
    By means of such an arrangement i) all platforms can simultaneously be rotated about a vertical axis, or ii) the central platform can be rotationally anchored and the outer platforms can be pivoted about a vertical axis passing through the connection point with the respective connecting element, or iii) it All platforms can be rotated simultaneously and the outer platforms can be swiveled additionally. By both movements, so turning and pivoting, a tracking of the respective platforms can be done with the sun, which significantly increases the efficiency of a solar power plant carried thereon.
    Accordingly, herein, under the " anchoring " the central platform has both a rotatable connection to the bottom of the water body, e.g. Seabed, for example, by means of conventional anchor and anchor chains as well as a firm stand on the water bottom to understand. In the latter case, of course, the central platform is anchored rotatably. An essentially non-rotatable anchoring is also given by the provision of several conventional anchors. -2-
    Under " vertical axis " It should be understood herein to mean an axis substantially normal to the plane of the respective platform.
    Furthermore, the outer platforms can be anchored, as long as this anchorage does not affect the pivotability. For example, conventional anchors with sufficiently long anchor chains can be used.
    In order to realize the above three modes of movement i) to iii), according to the present invention, a distinction is thus made between the following embodiments: 1) The central platform is anchored in a rotationally fixed manner and one or more of the outer platforms are pivotably mounted on the respective connecting element. 2) The anchored central platform is rotatable about a, preferably substantially extending through the anchor point, vertical axis, and the outer platforms are rotatably connected to the respective connecting element. 3) The anchored central platform is rotatable about a, preferably substantially extending through the anchor point, vertical axis, and one or more of the outer platforms are pivotally mounted on the respective connecting element.
    Depending on which of the platforms is moved, the vertical axis passes through different points. When pivoting the outer platforms, the vertical axis extends substantially through the connection or bearing point of the outer platform with the respective connecting element. When rotating the anchored central platform and thus the entire arrangement, the vertical axis passes substantially through the anchor point, which is not the anchor at the seabed, but the junction of the platform with the anchor chain meant. -3- * > * * * i k * ι ♦ »4« ·· ** * * * * * ι «β» »** •• 4 4 ι ι * * · 4« · * Μ Μ * «
    For pivoting suitable connections and bearings between the connecting elements and the outer platforms are provided, as they are known in the art.
    Although the material of the connecting elements is not particularly limited, in view of a stable anchoring to the central platform and the power transmission when turning or pivoting should preferably be used against corrosion protected stable steel structures, which will be more apparent later in connection with the drawings.
    Both the pivoting of the outer platforms and the rotation of the entire arrangement of floating platforms is preferably carried out by means of one or more drive units, which are attached to the respective platforms. For this purpose, conventional ship engines with screw drive are preferably used. With regard to the use of the platform arrangement for solar power plants, particular preference is given to electric motors which can be operated with part of the solar energy obtained.
    Preferably, a plurality of drive units per platform are provided. As a result, the power required for the movement can be distributed among several motors, and some motors can be used to move the respective platforms in one direction and others to move in the opposite direction.
    Furthermore, when rotating the overall assembly, it is preferred that the force required for it be provided exclusively or at least primarily by drive elements on the outer platforms, but certainly not exclusively by drive elements on the central platform, as this will apply the moment required for rotation with less force can.
    Both the pivoting of the outer platforms and the rotation of the overall assembly preferably comprises a rotation of at least 180 °, more preferably at least 210 °, even more preferably at least 240 °, in particular -4- at least 270 °. This allows for the geographical latitude and the season adapted use of the inventive arrangement as a carrier of a solar power plant. The rotation of the overall arrangement may in preferred embodiments also include a rotation through 360 °, for which a corresponding mounting of the anchor chain on the central platform is required.
    In further preferred embodiments, the respective connecting elements are non-rotatably connected to the central platform at at least two articulation points in order to optimally transmit the rotational force exerted by the driving elements and acting on the corresponding platform (s), i. either from the central platform to the outer platforms or vice versa, preferably vice versa.
    Especially, but not only in embodiments in which the central platform has a firm footing on the body of water, i. especially seabed, the connecting elements are preferably height adjustable connected to the central platform to compensate for differences in height due to tides or sea state.
    The construction, the dimensions and the shape of the platforms of the arrangement according to the invention are not particularly limited. Preferably, a lightweight construction is chosen for the outer platforms, e.g. using inflatable buoyancy or floats as well as pneumatic concentrators. The central platform on which, when used for off-shore solar power plants, preferably the heavier parts of the power plant, ie generators, turbines or the like are stored, is preferably realized in a conventional construction of offshore oil or gas platforms.
    The dimensions also depend on the number of outer platforms. For example, with a given area of solar collectors, these can be distributed over a few larger or several smaller platforms. In particular, the manufacturing and operating costs become the determining parameters. * * * 4 * * * * * * * * ♦ 4 »·« ». ···········································. The dimensions of the central platform and the outer platforms may, for example, be between a few meters and several hundred meters. In addition, the dimensions of the central platform and the outer platforms must be matched to each other and to the shape and length of the fasteners.
    The cross-sectional shape of the platforms is not particularly limited, but preferably, square platforms are selected in view of stability against drift or square platforms in view of favorable manufacturing.
    In a second aspect, the invention relates to the above-described use of the inventive arrangement of floating platforms according to the first aspect for supporting a solar energy recovery plant, wherein in preferred embodiments the entire sun tracking assembly is rotated and / or the outer platforms are pivoted become.
    BRIEF DESCRIPTION OF THE DRAWINGS
    Preferred embodiments of the invention will be described in detail below with reference to the accompanying drawings, in which:
    Fig. 1 is a schematic representation of an embodiment of the inventive arrangement of floating platforms with three outer platforms.
    Fig. 2 is a schematic representation of another embodiment of the inventive arrangement of floating platforms with four outer platforms. Fig. 3 is a schematic representation of the articulation of a connecting element on the central platform.
    4 is a detail enlargement of a detail of FIG. 3.
    DETAILED DESCRIPTION OF THE DRAWINGS
    In Fig. 1, a preferred embodiment of the inventive arrangement of floating platforms with three outer platforms 2, which are connected via respective connecting elements 3 with a central platform 1, is shown. The outer platforms 2 can be pivoted about the bearing point on the respective connecting element 3. The central platform is assumed anchored in this embodiment as rotationally fixed. The arrows each symbolize the position of carried on the outer platforms solar panels with respect to the direction.
    In Fig. 1a, the position of the outer platforms in the morning is shown schematically. The arrangement is in such a position that the solar panels are oriented to the east. During the day, the outer platforms 2 are tracked by means of drive elements (not shown), so that the solar panels are facing south at noon, as seen in Fig. 1b, and toward the west in the evening, see Fig. 1c. Thus, the outer platforms 2 are pivotable by at least 180 °. After sunset, the outer platforms 2 can be pivoted back to the starting position.
    In addition to this pivoting, the entire assembly could also be rotated about a vertical axis through the central platform if it is not anchored in rotation. In this case, the outer platforms 2 need not be pivotable through 180 °.
    FIG. 2 shows a further embodiment of the invention with four outer platforms 2, in turn connected via respective connecting elements 3 to a central platform 1. Here are the outer platforms 2 rotatably connected to the connecting elements 3, that is not pivotable. For this, however, the central platform 1 and thus the entire arrangement is rotatable about a vertical axis extending through the central platform 1, as indicated by the curved arrow at the top right. The tracking is done in this case by turning all platforms.
    With appropriate choice of anchoring the central platform 1, it is also possible to rotate through 360 °, in which case no rotation in the opposite direction, i. back to the starting position for the next day, provided that the submarine cable for discharging the power generated comprises a swivel joint. -7-
    * * · ··· «I * ·
    Fig. 3 is a schematic view of the rotationally fixed connection between the central platform 1 and a connecting element 3 with an outer platform 2. It can be seen that the connecting element 3 is a strut-stabilized scaffold, which is a two points on the Central platform 1 is articulated.
    Furthermore, the anchoring of the central platform can be seen, which is exemplified here by four schematically indicated anchor chains 4. The anchor chains 4 are connected to a stationary vertical pin 6. The central platform 1 can rotate as a result of a rotatable embodiment of the connection to the pin arranged in the axis of rotation and is thus rotatably anchored in this embodiment. In addition, it is - as the outer platforms - designed as a floating platform, as indicated by two pontoons 5. In addition, the construction of the central platform 1 can be seen in the form of a stably braced with bracing Ge framework.
    Finally, Fig. 4 is an enlarged detail of Fig. 3, namely at the steering point of the connecting element 3 on the central platform, in which the two articulation points 3 'are marked. Furthermore, it can be seen that with such an articulation, the connecting element 3 and thus the outer platform 2 are height-adjustable connected to the central platform 1, since the connecting element 3, for example, in strong waves, along the linkage 1 'up and can slide. Despite possibly variable relative height of the articulation point in operation, a torque can be transmitted in every situation between the central platform and the outer platforms
    The arrangement of the present invention thus provides for the first time the possibility of several floating platforms - and preferably those who wear an off-shore solar power plant - coordinated to move, in particular, so as to effect a tracking of solar panels carried thereon depending on the position of the sun to be able to. -8th -
