Description

Technical Field

[0001] The invention relates to a photovoltaic support, in particular to a wind-resistant and adjustable mountain photovoltaic support structure. Background Art

[0002] With the development of solar energy application technology, photovoltaic power generation has been increasingly valued and applied; photovoltaic power generation projects require a large amount of land resources for photovoltaic panel layout, but as the number of projects increases, the available land resources decrease, and the number of mountain photovoltaic projects has increased significantly.

[0003] Photovoltaic power generation devices consist of brackets and solar panels laid on the brackets. In photovoltaic power station projects, the pile foundation and installation projects of photovoltaic brackets are the largest parts of the civil engineering and electromechanical engineering of the entire photovoltaic power station. Photovoltaic brackets generally adopt a portal steel frame structure, with columns supporting inclined beams, purlins installed on the inclined beams, and photovoltaic modules installed on the purlins.

[0004] Photovoltaic brackets are installed in mountains and may be affected by environmental factors such as strong winds. Photovoltaic brackets may shake during use, and the shaking may cause damage to photovoltaic panels. When wind forces from different directions act on the surface of the photovoltaic brackets, the photovoltaic brackets lack the ability to adaptively adjust them, which can easily cause the photovoltaic panels to tilt or flip, and reduce the stability of the photovoltaic panels and the efficiency of photovoltaic power generation. Due to the terrain of the mountains, there are differences in the installation heights of photovoltaic panels, which in turn affects the layout of the photovoltaic brackets. Summary of the invention

[0005] The main purpose of the present disclosure is to provide a wind-resistant and adjustable mountain photovoltaic support structure to effectively solve the problems raised by the inventor in the above background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] The U-shaped rear bracket is connected to the rear frame by the U-shaped front bracket and the U-shaped rear bracket is connected to the rear frame by the U-shaped front bracket and the U-shaped rear bracket.

[0008] Preferably, two photovoltaic bases are fixedly mounted on the surface of the windproof shaft, the photovoltaic panel body is fixedly mounted on the top surfaces of the two photovoltaic bases, a servo motor is fixedly mounted on the side of one of the mounting plates, and the output shaft of the servo motor is fixedly connected to one end of the windproof shaft.

[0009] Preferably, two extension rods are fixedly connected to the windproof shaft, and pressure sensors are fixedly installed on one side of the two extension rods close to the photovoltaic panel body, and the detection ends of the two pressure sensors are in contact with the back side of the photovoltaic panel body.

[0010] Preferably, a controller is fixedly mounted on the bottom of one of the extension rods, and the pressure sensor and the servo motor are both electrically connected to the controller.

[0011] Preferably, the first ring and the second ring are rotatably mounted on the two mounting plates, and the two second rings are located between the two first rings, the two ends of the opening of the U-shaped front bracket are respectively fixedly connected to the two first rings, and the two ends of the opening of the U-shaped rear bracket are respectively fixedly connected to the second rings.

[0012] Preferably, a distance-adjusting screw is rotatably installed between the No. 1 floor rail and the No. 2 floor rail, and the distance-adjusting screw is arranged parallel to the slide rail rod, and two second moving blocks are threadedly installed on the distance-adjusting screw, and the bottom end of the U-shaped front bracket and the bottom end of the U-shaped rear bracket are respectively movably connected to the two second moving blocks.

[0013] Preferably, a control cabin is opened inside the No. 1 floor track, and an operating shaft is rotatably installed on the upper end of the control cabin, and a bevel gear 1 is fixedly installed on the part of the operating shaft located in the control cabin, one end of the pitch adjusting screw rod extends into the control cabin and is fixedly connected to bevel gear 2, and bevel gear 1 is meshed with bevel gear 2, and the upper end of the operating shaft extends outside the No. 1 floor track and is fixedly connected to a hand wheel.

[0014] Preferably, a lower convex edge is fixedly connected to the front of the No. 1 floor rail, an upper convex edge is fixedly connected to the back of the No. 2 floor rail, and mounting holes are provided on the lower convex edge and the upper convex edge.

[0015] Preferably, the left sides of the No. 1 floor rail and the No. 2 floor rail are both slidably connected with docking columns, and the right sides of the No. 1 floor rail and the No. 2 floor rail are both provided with alignment holes, and the docking columns are adapted to the alignment holes.

[0016] In view of this, compared with the prior art, the beneficial effects of the present invention are:

[0017] (I) In this application, when installed in mountainous areas, multiple photovoltaic support structures can be spliced ​​to achieve array distribution, such asFigure 6 As shown, the two photovoltaic support structures are connected longitudinally, and the No. 1 ground track on one photovoltaic support structure is attached to the No. 2 ground track on the other photovoltaic support structure, that is, the upper convex edge and the lower convex edge are staggered and stuck, so that the two photovoltaic support structures can be distributed. Figure 8 As shown, four photovoltaic support structures are connected horizontally, the docking posts on one photovoltaic support structure are inserted into the alignment holes on another photovoltaic support structure, and the ground rails are aligned, so that multiple photovoltaic support structures can be quickly distributed in an array, which is suitable for application in relatively flat areas in the mountains.

[0018] (ii) In the present application, due to the terrain of the mountain, the heights of the photovoltaic panels after installation may be uneven. At this time, the hand wheel can be turned to rotate the operating shaft and drive the bevel gear one to rotate. Under the meshing transmission with the bevel gear two, the pitch-adjusting screw is rotated, and the pitch-adjusting screw is a bidirectional screw. Then, the two second moving blocks on it move toward or away from each other. When the two second moving blocks move toward each other, the U-shaped front bracket and the U-shaped rear bracket move together, and then the height of the photovoltaic panel body is increased. Similarly, the two second moving blocks move away from each other, so that the U-shaped front bracket and the U-shaped rear bracket will start to move, that is, the height of the photovoltaic panel body is lowered, so that the photovoltaic panel bodies in the same row can be set to the same height, which is more beautiful and can ensure the sun-facing area of ​​the photovoltaic panel body.

[0019] (III) In the present application, when encountering wind resistance, if the windward area of ​​the photovoltaic panel body is large, it is easy to cause loss. Through the coordinated use of the pressure sensor, the controller and the servo motor, when the photovoltaic panel body is subjected to wind resistance, it will collide with the detection end of the pressure sensor, and the two pressure sensors are distributed on both sides of the windproof shaft, so that when the photovoltaic panel body squeezes any one of the pressure sensors, if the preset value is reached, the controller receives the signal and controls the servo motor to work. The servo motor drives the windproof shaft to rotate, so as to rotate the photovoltaic panel body from an inclined state to a horizontal state, so as to reduce wind resistance, achieve a good wind resistance effect, and extend the service life of the photovoltaic panel.

[0038] When installing in mountainous areas, multiple photovoltaic support structures can be spliced ​​to achieve array distribution, such as Figure 6 As shown, two photovoltaic support structures are connected longitudinally, and the No. 1 ground track 2 on one photovoltaic support structure is attached to the No. 2 ground track 3 on the other photovoltaic support structure, that is, the upper convex edge 201 and the lower convex edge 301 are staggered and stuck, so that the two photovoltaic support structures can be distributed.

The servo motor 12 drives the windproof shaft 9 to rotate, so as to rotate the photovoltaic panel body 1 from an inclined state to a horizontal state, so as to reduce wind resistance, achieve a good wind resistance effect, and extend the service life of the photovoltaic panel.
