Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket technology, specifically to an adjustable flat single-axis photovoltaic power generation system mounting bracket. Background Technology

[0002] Concentrated photovoltaic (CPV) technology combines optical technology with new energy sources. It uses optical elements such as lenses or mirrors to concentrate sunlight from a large area onto a very small area, which is then directly converted into electrical energy by high-efficiency photovoltaic cells. However, CPV power generation systems require high-precision solar synchronous tracking devices and numerous rotation and connection mechanisms. To obtain a large number of horizontal support units, the rotating shafts need to have high rigidity, resulting in relatively high maintenance costs and making them less reliable than crystalline silicon photovoltaic systems. Furthermore, the efficiency of photovoltaic cells decreases as the cell operating temperature increases; uneven temperature distribution within the cells will lead to reduced efficiency. The CPV system of this project adopts microchannel cooling technology. Due to the high temperature and high radiation in the desert area, the heat dissipation efficiency of the concentrated photovoltaic power generation system is poor, which seriously affects the power generation efficiency of the system. When the original CPV system support was dismantled, the main steel structure components were 50x3 square steel pipes with lengths of 2520, 2120, 4117 and 2230 mm, 89x4 round steel pipes with a length of 2280 mm, and No. 10 light channel steel with main lengths of 2060, 1250 and 635 mm. The project does not have modular trapezoidal frames, so the original prefabricated support cannot be used directly. Utility Model Content

[0003] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a reasonably designed and easy-to-use adjustable flat single-axis photovoltaic power generation system mounting bracket, which can effectively solve the defects of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: it includes a support frame and a mounting rod, wherein the support frame is U-shaped, and a mounting rod is provided on the upper side inside the support frame, with both ends of the mounting rod abutting against the vertical rods on both sides of the support frame; it also includes:

[0005] A support mechanism is provided inside the horizontal plate on the lower side of the support frame;

[0006] The connecting frame consists of several connecting frames, all of which are arranged in an "L" shape. The connecting frames are equally distributed on both sides of the support frame. The horizontal plates on the lower side of several connecting frames on the same side are connected, and the horizontal plates on the lower side of the connecting frames adjacent to the support frame are connected to the vertical rods of the support frame.

[0007] Connecting rods, there are several connecting rods, and they are arranged one-to-one on the upper side inside the connecting frame. The connecting rods and the mounting rods are arranged on the same plane, and the other end of the connecting rods abuts against the outer wall of the adjacent connecting frame.

[0008] The fixing plates are multiple in number, arranged from left to right with their ends touching each other, and are suspended above the connecting rod and the mounting rod.

[0009] Angle rods, there are several angle rods, two of which are symmetrically inserted into the mounting rod, and the other several are inserted into the connecting rods one-to-one. The angle rods are arranged in a "U" shape, and the vertical rods at both ends of the angle rods are fixedly connected to the fixing plate respectively.

[0010] A synchronous rotation mechanism is provided, which is installed inside the vertical rods of the support frame and the connecting frame, and is connected to several connecting rods and mounting rods;

[0011] The above technical solution involves installing photovoltaic panels on a fixed plate and moving the support mechanism out from the horizontal plate under the support frame to support the support frame and the connecting frames on both sides. The fixed plate for installing photovoltaic panels is supported by angle rods, ensuring that each photovoltaic panel has a 15° tilt angle to meet certain sunlight reception requirements. When the angle of the photovoltaic panel needs to be adjusted, a synchronous rotation mechanism drives several connecting rods and mounting rods to rotate. The connecting rods and mounting rods drive the angle rods, which in turn drive the fixed plate to rotate. The fixed plate then drives the photovoltaic panel to rotate, improving the photovoltaic panel's reception efficiency.

[0012] As a further improvement of this utility model, the front and rear sides of the fixed plate are movably inserted with plug rods, and the plug rods are symmetrically inserted and fixed with connecting springs inside. The other end of the connecting springs is fixed to the inner wall of the fixed plate. The front and rear sides of the fixed plate are suspended with limiting baffles, and the limiting baffles are fixed to the outer ends of several adjacent plug rods. The plug rods on the two symmetrical limiting baffles are staggered.

[0013] With the above technical solution, when installing photovoltaic panels, the limiting baffles are moved to both sides, and the photovoltaic panels are locked between the two corresponding limiting baffles at the front and back. The position of the limiting baffles is limited by the connecting spring, which facilitates the installation of photovoltaic panels.

[0014] As a further improvement of this utility model, the limiting baffle is provided with a limiting groove on the side wall adjacent to the fixed plate, and the lower side of the limiting groove is inclined to the side away from the fixed plate.

[0015] The above technical solution can better limit the position of photovoltaic panels.

[0016] As a further improvement of this utility model, the support mechanism includes:

[0017] The telescopic link consists of two telescopic links, which are symmetrically arranged on both sides of the support frame crossbar. The support rods on both sides of the middle end of the telescopic link are screwed with moving blocks through bearings. The moving blocks are slidably arranged in the sliding grooves on the lower side of the support frame crossbar.

[0018] Two bidirectional lead screws are provided, which are connected end to end and screwed into the crossbar of the support frame via bearings. The two ends of the two bidirectional lead screws are respectively screwed into the moving blocks on both sides of the same telescopic connecting rod. One end of one of the bidirectional lead screws is fixed with a support motor, which is embedded and fixed in the support frame.

[0019] The support plate consists of four plates, which are symmetrically arranged in pairs on the left and right sides inside the crossbar of the support frame. Rotating rods are screwed to both sides of the center of the upper surface of the support plate via shafts. The other end of the rotating rods is screwed to the support rods on both sides of the adjacent telescopic connecting rod via shafts.

[0020] With the above technical solution, during support, the support motor is started, which drives the bidirectional lead screw to rotate. This bidirectional lead screw drives another bidirectional lead screw to rotate, and the two bidirectional lead screws simultaneously drive the moving blocks at their respective ends to move. The moving blocks drive the support rod on the middle side of the telescopic connecting rod to rotate, and the support rods on both sides of the telescopic connecting rod drive the rotating rod to rotate. The rotating rod drives the support plate to move, so that the support plate moves out of the support frame, increasing the contact area between the support frame and the ground and providing support force to the support frame.

[0021] As a further improvement of this utility model, the synchronous rotation mechanism includes:

[0022] A rotating motor is embedded and fixed in a vertical rod on one side of the support frame. A drive gear is fixed on the output shaft of the rotating motor. A linkage gear meshes with the upper side of the drive gear. The diameter of the linkage gear is larger than that of the drive gear. The linkage gear is screwed to the vertical rod of the support frame through a shaft.

[0023] The rotating rods are of several types, and each of them is fixed to one end of the connecting rod and the mounting rod. The rotating rods are screwed into the vertical rod on one side of the support frame and the vertical rod of the connecting frame through bearings. The linkage gear is engaged with the tooth groove on the outer ring wall of the rotating rod inside the support frame.

[0024] Linkage rods, there are several linkage rods, and they are fixed one by one to the other end of the connecting rod. The linkage rods are movably inserted into the vertical rods of the adjacent connecting frame and support frame. A square rod is fixed on the outer end of the linkage rod, and the square rod is movably inserted into the adjacent rotating rod.

[0025] With the above technical solution, the rotating motor is started, and the rotating motor drives the linkage gear to rotate through the drive gear. The linkage gear drives the rotating rod inside the vertical rod on one side of the support frame to rotate. The rotating rod drives the mounting rod to rotate and at the same time drives the square rod inside it to rotate. The square rod drives the linkage rod to rotate, and the linkage rod drives the connecting rod to rotate, thereby simultaneously driving several angle rods to rotate.

[0026] As a further improvement of this utility model, each of the crossbars of the connecting frame is provided with a connecting screw, the outer end of which is screwed onto the side wall of the crossbar of the adjacent connecting frame, and the connecting screw in the connecting frame adjacent to the support frame is screwed onto the crossbar of the support frame.

[0027] The above technical solution facilitates the connection between the connecting frame and the support frame.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows: The adjustable flat single-axis photovoltaic power generation system mounting bracket of this utility model has an angle rod set on the underside of the fixing plate for mounting the photovoltaic panel, so that the photovoltaic panel has a tilt angle of 15° in the initial state, which meets the requirements for receiving certain sunlight and improves the light reception efficiency. This utility model has the advantages of reasonable setting and low manufacturing cost. Attached Figure Description

The other end of the rotating rod 3-6 is screwed with a shaft to the support rod on both sides of the adjacent telescopic connecting rod 3-1.

[0050] Example 3:

[0051] See Figure 2 , Figure 3 As shown, based on Embodiment 1, the synchronous rotation mechanism 8 includes:

[0052] A rotating motor 8-1 is embedded and fixed in the vertical rod on the left side of the support frame 1. A drive gear 8-2 is fixed on the output shaft of the rotating motor 8-1. A linkage gear 8-3 meshes with the upper side of the drive gear 8-2. The diameter of the linkage gear 8-3 is larger than that of the drive gear 8-2. The linkage gear 8-3 is screwed to the vertical rod of the support frame 1 through a shaft.

[0053] Rotating rod 8-4, there are several rotating rods 8-4, and they are welded and fixed to the two ends of the connecting rod 5 and the mounting rod 2 respectively. The rotating rod 8-4 is screwed into the vertical rod on one side of the support frame 1 and the vertical rod of the connecting frame 4 through bearings. The linkage gear 8-3 is engaged with the tooth groove on the outer ring wall of the rotating rod 8-4 inside one side of the support frame 1.

[0054] Linkage rod 8-5, there are several linkage rods 8-5, and they are welded and fixed to the other end of the connecting rod 5 one by one.

[0055] When using this utility model, the photovoltaic panel is installed on the fixed plate 6. The support motor 3-4 is started, which drives the bidirectional lead screw 3-3 to rotate. This bidirectional lead screw 3-3 drives another bidirectional lead screw 3-3 to rotate. The two bidirectional lead screws 3-3 simultaneously drive the moving blocks 3-2 at their respective ends to move. The moving blocks 3-2 drive the support rod on the middle side of the telescopic connecting rod 3-1 to rotate. The support rods on both sides of the telescopic connecting rod 3-1 drive the rotating rod 3-6 to rotate. The rotating rod 3-6 drives the support plate 3-5 to move, causing the support plate 3-5 to move out of the support frame 1. This increases the contact area between the support frame 1 and the ground, providing support force to the support frame 1, thereby supporting the support frame 1 and the connecting frames 4 on both sides, and fixing the photovoltaic panel. The photovoltaic panel 6 is supported by angle rods 7, giving each panel a 15° tilt angle to ensure adequate sunlight reception. When the angle of the photovoltaic panel needs to be adjusted, the rotating motor 8-1 is activated. The rotating motor 8-1 drives the linkage gear 8-3 to rotate via the drive gear 8-2. The linkage gear 8-3 drives the rotating rod 8-4 inside the vertical rod on one side of the support frame 1 to rotate. This rotating rod 8-4 drives the mounting rod 2 to rotate, and simultaneously drives the square rod 8-6 inside it to rotate. The square rod 8-6 drives the linkage rod 8-5 to rotate, and the linkage rod 8-5 drives the connecting rod 5 to rotate, thereby simultaneously driving several angle rods 7 to rotate. The angle rods 7 drive the fixed plate 6 to rotate, and the fixed plate 6 drives the photovoltaic panel to rotate, improving the photovoltaic panel's reception efficiency.

[0056] Compared with the prior art, the beneficial effects of this specific embodiment are as follows:

[0057] 1. An angle rod 7 is provided on the underside of the fixing plate 6 for installing photovoltaic panels, so that the photovoltaic panels have a tilt angle of 15° in the initial state, which meets the requirements for receiving certain sunlight and improves the light reception efficiency.

[0058] 2. A support mechanism 3 is provided inside the crossbar of the support frame 1. When in use, the support mechanism 3 is moved out of the support frame 1 for easy support. When not in use, it can be stored to reduce the area occupied.

[0059] 3. The mounting rod 2 and the connecting rod 5 are connected by a synchronous rotation mechanism 8, which allows the mounting rod 2 and the connecting rod 5 to rotate synchronously, thereby facilitating the synchronous rotation of several fixed plates 6;

[0060] 4. In the synchronous rotation mechanism 8, the linkage gear 8-3 is larger than the drive gear 8-2. When the drive gear 8-2 drives the linkage gear 8-3, it can avoid the rotation angle being too large, thus affecting the required rotation angle.

[0061] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
