Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a photovoltaic module fixing support for a photovoltaic power station. Background Technology

[0002] Photovoltaic power plants, also known as solar power plants, are new energy power generation facilities that use solar photovoltaic technology to directly convert the light energy of solar radiation into electrical energy. They have the advantages of being clean, renewable, and environmentally friendly, and are an important way to achieve energy structure transformation. The main components include photovoltaic modules (solar panels), inverters, brackets, DC and AC cables, power distribution equipment, and grid connection equipment. Among them, the photovoltaic bracket is particularly important for photovoltaic modules, ensuring that the solar panels work stably at the optimal angle and position, while also coping with various environmental conditions.

[0003] A current document with publication number CN204539058U discloses a photovoltaic support structure, including a first column, a second column, corner connectors, a diagonal beam, and a crossbeam. One end of the first and second columns is connected to one end of the diagonal beam via the corner connectors, and the crossbeam is fixed to the other end of the diagonal beam. The first column, second column, corner connectors, diagonal beam, and crossbeam are all made of glass fiber reinforced plastic. This utility model features a simple structure, high strength, and good corrosion resistance.

[0004] The photovoltaic support structure disclosed above cannot be flexibly arranged according to the installation space of the photovoltaic panels. It can only install the photovoltaic panels facing one direction. If the installation space of the photovoltaic panels requires the photovoltaic panels to be installed at multiple angles to better and maximize the absorption of solar energy, the support structure cannot be flexibly adjusted according to the needs. Utility Model Content

[0005] The purpose of this utility model is to provide a photovoltaic module fixing bracket for a photovoltaic power station, which solves the problem that the existing photovoltaic module fixing brackets for photovoltaic power stations cannot be flexibly adjusted according to the installation space area and installation requirements of the photovoltaic panels.

[0006] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes:

[0007] Two connecting base frames;

[0008] Two steering components are respectively disposed on the top of two connecting base frames, and an installation bar is provided between the two steering components. Each steering component includes a lifting component disposed on the top of the connecting base frame and an orienting component disposed on the top of the lifting component. The orienting component consists of at least three mutually hinged support rods. Each support rod includes a hollow rod, and a pull-out tube slides inside the hollow rod. One end of the pull-out tube is fixed with a connecting tube head.

[0009] Preferably, the lifting component is used to change the tilt angle and height of the support rod. The lifting component includes a hollow cylinder disposed on the top of the connecting base frame. At least three hollow screw rods are disposed inside the hollow cylinder and are interlocked. One end of the hollow cylinder and one end of the hollow screw rod are rotatably connected to an internal thread drive ring. The hollow screw rod is threadedly connected to the internal thread drive ring corresponding to the interlocking position. One end of the innermost hollow screw rod is rotatably connected to the support rod.

[0010] Preferably, the connecting base frame includes at least three connecting base plates, the connecting base plates have an inner groove, a pull plate slides inside the inner groove, and a limit member is provided on the outside of the pull plate.

[0011] Preferably, the connecting base plate has a limiting groove inside and a limiting hole on its outer surface. The limiting component includes a limiting plate fixed to the outer surface of the pull-out plate, and a screw is threadedly connected to the inside of the limiting plate.

[0012] Preferably, both the inner thread drive ring and the outer surface of the screw are provided with a rubber anti-slip layer.

[0013] Preferably, the outer surface of the support rod is provided with two mounting strips, one of which is located on the outer surface of the hollow rod, and the other is located on the outer surface of the connecting pipe head.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] Based on the required installation orientation and angle of the photovoltaic panels, screw the screw out of the limiting hole, and then rotate the internal thread drive ring in the corresponding lifting component to make the hollow screw connected to it rise and fall vertically. This adjusts the height and tilt angle of the support rod fixed on this lifting component. When the lifting component adjusts the tilt angle of the support rod connected to it, the distance between adjacent lifting components changes through the relatively sliding pull plate and the connecting base plate. After adjusting the angle of each support rod to a suitable position, screw the screw into the limiting hole to complete the overall orientation and shape adjustment of the bracket, making it suitable for various installation space layout requirements.

Detailed Implementation

[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] This embodiment provides a technical solution: a photovoltaic module fixing bracket for a photovoltaic power station, such as... Figure 1-4 As shown, the device includes two connecting base frames 1 and two adjusting components 2 respectively disposed on the top of the two connecting base frames 1. The connecting base frame 1 includes at least three connecting base plates 11. The interior of the connecting base plate 11 is provided with an inner groove 12. A pull plate 13 slides inside the inner groove 12. The pull plate 13 and the connecting base plate 11 in adjacent connecting base frames 1 are fixedly connected to each other. A limiting member 14 is provided on the outside of the pull plate 13. A limiting groove 15 communicating with the inner groove 12 is provided inside the connecting base plate 11. A limiting hole 16 is provided on the outer surface of the connecting base plate 11. The number of limiting holes 16 can be set according to the length of the connecting base plate 11, and the limiting holes 16 are located above the limiting groove 15. The limiting member 14 includes a limiting plate 141 fixed to the outer surface of the pull plate 13. The limiting plate 141 passes through the inside of the limiting groove 15. A screw 142 is threadedly connected inside the limiting plate 141. The diameter of the screw 142 is adapted to the diameter of the limiting hole 16.

[0024] An installation bar 3 is provided between the two directional components 2. The directional component 2 includes a lifting component set on the top of the connecting base frame 1 and an orienting component set on the top of the lifting component. The orienting component consists of at least three support rods 21 that are hinged to each other. Adjacent support rods 21 are hinged to each other by hollow rods 211 with opposite ends and connecting pipe heads 312. The support rod 21 includes a hollow rod 211. A pull tube 212 slides inside the hollow rod 211. A connecting pipe head 213 is fixed to one end of the pull tube 212. Two installation bars 3 are provided on the outer surface of each support rod 21. One installation bar 3 is provided on the outer surface of the hollow rod 211, and the other installation bar 3 is provided on the outer surface of the connecting pipe head 213. The photovoltaic panel is installed and fixed above the support rod 21 by the installation bars 3.

[0025] The lifting component is used to change the tilt angle and height of the support rod 21. The lifting component includes a hollow cylinder 22 fixed to the top of the connecting base plate 11. The hollow cylinder 22 has at least three hollow screw rods 23 that are nested together. Two vertical grooves are formed on the inner surface of both the hollow cylinder 22 and the inner surface of the hollow screw rods 23. Two connecting blocks are fixed at one end of the hollow screw rods 23 and slide in the two grooves respectively. By relying on the limiting between the connecting blocks and the grooves, the hollow screw rods 23 can complete the vertical lifting movement. One end of the hollow cylinder 22 and one end of the hollow screw 23 are both rotatably connected to an internal thread drive ring 24. The hollow screw 23 is threadedly connected to the internal thread drive ring 24 corresponding to the sleeve position. The outer surfaces of the internal thread drive ring 24 and the screw 142 are provided with a rubber anti-slip layer to prevent hand slippage when rotating them. One end of the innermost hollow screw 23 is rotatably connected to the support rod 21. One end of the hollow screw 23 rotates on the hollow rod 211 or the connecting pipe head 213.

[0026] In use: According to the direction and angle of the photovoltaic panel installation, screw 142 in the connecting base frame 1 is screwed out of the limiting hole 16. Then, the internal thread drive ring 24 in the corresponding lifting component can be rotated. When the internal thread drive ring 24 rotates, the hollow screw 23 connected to it will move vertically up and down, thereby adjusting the height and tilt angle of the support rod 21 fixed on this lifting component. When the lifting component adjusts the tilt angle of the support rod 21 connected to it, the distance between adjacent lifting components will also change slightly. This change is adjusted by the relatively sliding pull plate 13 and the connecting base plate 11. After adjusting the angle of each support rod 21 to the appropriate arrangement of the photovoltaic panel installation, screw 142 can be screwed into the limiting hole 16 to complete the overall direction and shape adjustment of the bracket.

[0027] Depending on the length of the photovoltaic panel installed on the support rod 21, the overall length of the support rod 21 can be adjusted to accommodate it. The screw 142 is screwed out of the limiting hole 16, and the pull plate 13 is pulled out or pushed in from the inner groove 12 to drive the hollow rod 211 and the pull tube 212 in the support rod 21 to slide relative to each other. After the overall length of the support rod 21 is changed, the angle will inevitably change. At this time, the hollow screw 23 can be raised and lowered by rotating the internal thread drive ring 24 to adjust the overall angle of the support rod 21. After adjustment, the screw 142 is screwed into the limiting hole 16 to fix the bracket and prevent the bracket from easily changing later.

[0028] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
