Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a flexible, retractable and rotatable photovoltaic bracket. Background Art

[0002] At present, photovoltaic panels are deployed in large numbers in Gobi Desert or desert areas. When the wind is strong, the photovoltaic panels are easily affected by the wind and blown over or down, causing huge losses. And the strong wind and sand can easily accumulate dust on the surface of the photovoltaic panels, resulting in the need for frequent cleaning, which is not conducive to the later maintenance of the photovoltaic panels. Therefore, it is necessary to design a flexible, retractable and rotating photovoltaic bracket to solve the above problems. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a flexible and retractable rotating photovoltaic bracket to solve the problem that the photovoltaic panels in the prior art may be blown down when the wind is strong and easily covered by wind and sand.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] The flexible, retractable and rotating photovoltaic bracket includes four groups of retractable brackets. The top of the retractable brackets is connected with supporting steel strands to form a rectangular support frame. The surface of the rectangular support frame is slidably connected with a folding photovoltaic panel, and one end of the folding photovoltaic panel is tied to the supporting steel strands. Two winches are respectively arranged on both sides below the rectangular support frame. The winches are connected with the stretching steel strands, and one end of the stretching steel strands passes around the supporting steel strands from above and is connected to the movable end of the folding photovoltaic panel.

[0006] Preferably, the bottom end of the telescopic bracket is fixed to the ground through a concrete pile foundation, and the top end of the telescopic bracket is connected with a buckle.

[0007] Preferably, one end of the supporting steel strand is welded to the top of one of the telescopic brackets, and the other end is passed through the buckles of the four groups of telescopic brackets in sequence and is connected to the steel strand fixed on the ground.

[0008] Furthermore, there is only one supporting steel strand, one end of which is fixed, and the other end passes through the ring buckles of the four telescopic brackets and is connected to the steel strand tie-down lugs. The overall rectangular frame is tightened by a steel strand tie-down lug.

[0009] Preferably, the foldable photovoltaic panel comprises a plurality of hinged photovoltaic panels, the photovoltaic panels are hinged by ear seats and pin shafts, and the corners of the photovoltaic panels are connected with climbing buckles and slidably connected with the supporting steel strands.

[0010] Furthermore, the foldable photovoltaic panel can be buckled with the supporting steel strands through a climbing buckle, and then slide on the supporting steel strands. When folded, it can be supported or lifted up by certain manual operations at the bottom of the photovoltaic panel to be folded, and then it can be folded smoothly with the operation of a winch; the winches on both sides cooperate with each other, and the same linear speed is used to control the unfolding and folding processes respectively.

[0011] Preferably, a spring is connected between the supporting steel strands and the steel strand tie-down lugs.

[0012] Furthermore, when the telescopic bracket is partially raised, the angle of the entire photovoltaic panel plane can be adjusted through the different heights of the four telescopic brackets. When the angle changes, the length of the steel strand will change. At this time, the spring can provide a certain feed amount, and the excess steel strand between the supporting steel strand and the steel strand tie-ground lug can be used to extend the side length of the entire supporting steel strand frame structure.

[0013] Preferably, adjacent telescopic brackets are cross-connected with diagonal steel strands, one end of the diagonal steel strand is connected to the top of the telescopic bracket, and the other end is connected to the bottom of the telescopic bracket through a spring.

[0014] Furthermore, when the telescopic bracket is partially raised, the angle of the entire photovoltaic panel plane can be adjusted through the different heights of the four telescopic brackets. When the angle changes, the length of the diagonal bracing steel strand will change. At this time, a certain feed amount can be provided by the spring to extend the length of the entire diagonal bracing steel strand.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The photovoltaic panels can be folded and retracted by pulling the steel strands. When strong winds come, the photovoltaic panels can be retracted to avoid being blown over or knocked down by the strong force, which will cause huge losses, especially in the Gobi Desert or desert areas.

[0017] 2. Reduced costs. In general, due to the need to consider strong wind loads, the bracket spacing is small and the foundation is large. With the present invention, the wind load is greatly reduced by shrinking the photovoltaic panels during strong winds, while increasing the bracket spacing and reducing the material investment.

[0018] 3. Improved efficiency. The efficiency of bracket installation has always restricted the construction period of photovoltaics. Due to the use of telescopic photovoltaic panels, the installers can install them at one section of the bracket. They can install one photovoltaic panel at a time. There is no need for personnel to move up and down during the installation process, which greatly improves efficiency and is suitable for mechanized operations.

[0019] 4. It is convenient to clean the photovoltaic panels. Each contraction process is a cleaning process. The dust on the surface will automatically slide off during the contraction process. It can also be cleaned through the water spray system fixed at the end during contraction, which is conducive to the later maintenance of the photovoltaic panels.

[0020] 5. By setting different telescopic bracket heights, the lateral rotation of the photovoltaic array can be adjusted to improve the power generation efficiency of the photovoltaic panels;

[0021] 6. The concrete foundation of the telescopic bracket is prefabricated, and the photovoltaic matrix construction can be carried out in a large-scale mechanized operation, which is convenient for automated construction in desert or Gobi areas. BRIEF DESCRIPTION OF THE DRAWINGS
