Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic flexible brackets, and specifically relates to an anti-wind photovoltaic flexible bracket. Background Technique

[0002] A photovoltaic flexible bracket is a frame that uses steel cables to assemble and support photovoltaic panels. With the explosive growth of photovoltaic installation volume, problems such as tight land resources, rising land use costs, and complex topographies of available land have become increasingly prominent. The rise of photovoltaic flexible brackets has greatly solved this problem. It can assemble and support photovoltaic panels at high altitudes. Compared with traditional fixed brackets and tracking brackets, which are limited by complex terrains and have limited row plate density and overall installation capacity, flexible brackets can adapt to complex landforms, greatly save land, and fully release the space under the panels.

[0003] When the photovoltaic flexible bracket supports the photovoltaic panel, it is distributed at high altitude where the wind force is relatively large. After the photovoltaic panel is fixed, the blowing of the wind will cause the photovoltaic panel to shake, with low stability, which affects the safe use of the photovoltaic panel, greatly reduces the service life of the photovoltaic panel and the flexible bracket, and easily causes faults in the photovoltaic panel. Therefore, we propose an anti-wind photovoltaic flexible bracket to solve the above-mentioned problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-wind photovoltaic flexible bracket to solve the problems in the above-mentioned background technique that the wind force is relatively large at high altitude, and after the photovoltaic panel is fixed, the blowing of the wind will cause the photovoltaic panel to shake, with low stability, which affects the safe use of the photovoltaic panel, greatly reduces the service life of the photovoltaic panel and the flexible bracket, and easily causes faults in the photovoltaic panel.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-wind photovoltaic flexible bracket, including a support rod, a support steel cable penetrates through the upper end of the support rod, a pressing block is clamped on the upper side of the support steel cable, a locking hoop a is attached to the lower side of the pressing block, a photovoltaic panel is attached to the upper side of the pressing block, threaded rods are connected to the lower side of the fitting end of the photovoltaic panel and the pressing block and the lower side of the fitting end of the pressing block and the locking hoop a, and fixing nuts are threadedly connected to the outside of the threaded rods;

[0006] A reinforcing steel cable penetrates through the middle of the support rod, a fixing plate is clamped on the upper side of the reinforcing steel cable, a locking hoop b is attached to the lower side of the fixing plate, a threaded rod is connected to the lower side of the fitting end of the fixing plate and the locking hoop b, a support seat is installed at the upper end of the fixing plate, a spring is connected inside the support seat, a positioning rod is connected to the end of the spring, and a dial rod is connected to the end of the positioning rod.

[0007] Preferably, a connecting plate is hinged to the outside of the fixing plate. A through hole is formed in the connecting plate. One end of an adjusting steel cable is connected to the end of the connecting plate, and the other end of the adjusting steel cable away from the connecting plate is connected to a threaded rod.

[0008] Preferably, the pressing block is in a "cross" shape structure, and the lower end surface of the pressing block is in an arc structure. This design can clamp the pressing block outside the supporting steel cable and cooperate with the use of the locking hoop a to fix it, and assemble the photovoltaic panel.

[0009] Preferably, the lower end surface of the fixing plate is in an arc structure, and the connecting plates are distributed equiangularly on the outside of the fixing plate. This design can clamp the fixing plate outside the reinforcing steel cable and cooperate with the use of the locking hoop b to fix it, and use the pulling of the connecting plates to reinforce and support the fixing plate.

[0010] Preferably, the supporting seat is in a "convex" shape structure, and the length of the supporting seat is less than the shortest distance between two pressing blocks. This design can ensure that the supporting seat smoothly moves to the position between the pressing blocks, fits with the photovoltaic panel, and supports the photovoltaic panel.

[0011] Preferably, the dial rod and the positioning rod are perpendicularly distributed. The dial rod penetrates through the lower end surface of the supporting seat and is slidably connected to the supporting seat. The positioning rod and the supporting seat form an elastic structure through a spring, and the positioning rod and the pressing block are engaged with each other. This design can lock the supporting seat and the pressing block and reinforce the connection stability between the photovoltaic panels.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) For this wind-resistant photovoltaic flexible bracket, when driving the dial rod to move, the dial rod drives the positioning rod to contract into the supporting seat, so that the supporting seat fits with the photovoltaic panel. When releasing the movement of the dial rod, the spring controls the positioning rod to be clamped into the pressing block, and the supporting seat supports the photovoltaic panel. Cooperating with fixing the fixing plate on the reinforcing steel cable, the connection stability between the photovoltaic panels is reinforced by the reinforcing steel cable, the fixing plate and the supporting seat, avoiding the low wind resistance stability of a single photovoltaic panel;

[0014] (2) For this wind-resistant photovoltaic flexible bracket, when pulling the adjusting steel cable, the adjusting steel cable is tightened. The symmetrically distributed adjusting steel cables can ensure the balanced force of the supporting steel cable and the reinforcing steel cable, and the interaction between the supporting steel cable, the adjusting steel cable and the reinforcing steel cable can keep the supporting steel cable and the reinforcing steel cable in tension, improving their wind resistance performance.
