Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a modular quick-installation photovoltaic support. Background Technology

[0002] Photovoltaic (PV) mounting systems are a crucial component of solar power systems, used to support and secure photovoltaic panels, ensuring their efficient reception of solar radiation. With the rapid development of photovoltaic technology, modular, quick-installation PV mounting systems have gradually become the industry mainstream due to their ease of installation and strong adaptability. However, in practical applications, especially in areas with significant terrain variations, the stability and adaptability of traditional mounting systems still face considerable challenges, necessitating a solution that can flexibly adjust height while maintaining stability.

[0003] Currently, common modular photovoltaic (PV) mounting systems typically use fixed legs and pre-assembled connectors for rapid assembly. They primarily rely on bolts or clips for connection, using a rigid support frame to secure the PV panels. Some systems employ simple hinge mechanisms for angle adjustment.

[0004] However, existing technologies have significant shortcomings: the height of the legs of traditional modular quick-install photovoltaic brackets is not adjustable. When the ground is uneven, the legs make uneven contact with the ground, resulting in unstable bracket installation, affecting the flatness and wind resistance of the photovoltaic panels, and may even cause structural damage due to uneven stress. Therefore, a modular quick-install photovoltaic bracket is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a modular quick-installation photovoltaic bracket, which aims to improve the instability of traditional modular quick-installation photovoltaic brackets when installed on uneven ground because the legs cannot be extended or retracted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular quick-install photovoltaic bracket includes a support plate, a support leg fixedly connected to the top of the support plate, a nut fixedly connected inside the support leg, a housing first sleeve on the outer wall of the support leg, a bushing fixedly connected to the outer wall of the housing first, a rotating shaft rotatably connected inside the bushing, a bevel gear first fixedly connected to the outer wall of the rotating shaft, and a lifting component provided on the outer wall of the bevel gear first.

[0008] The lifting assembly includes a second bevel gear, the top gear of which is connected to the outer wall of the first bevel gear, and a lead screw is fixedly connected to the bottom of the second bevel gear. A limit plate is fixedly connected to the bottom of the lead screw, and the lead screw is threaded inside the lead screw nut.

[0009] As a further description of the above technical solution:

[0010] One end of the rotating shaft is fixedly connected to a limiting shaft, and a housing two is slidably connected to the outer wall of the limiting shaft. A limiting key is fixedly connected to one side of the housing two, and a limiting groove two is opened on the outer wall of the housing one. The limiting key is slidably connected inside the limiting groove two.

[0011] As a further description of the above technical solution:

[0012] A connecting rod is fixedly connected to the outside of the second housing, and a handle is rotatably connected to the bottom of the connecting rod.

[0013] As a further description of the above technical solution:

[0014] A top cover is fixedly connected to the top of the housing, a fixing block is fixedly connected to the top of the top cover, and a cover tile is rotatably connected to the top of the fixing block.

[0015] As a further description of the above technical solution:

[0016] One of the cover tiles is fixedly connected to a connecting block, and another connecting block is fixedly connected to one side of the fixing block. The first connecting block is bolted to the top of the first bracket.

[0017] As a further description of the above technical solution:

[0018] The top of the fixed block is rotatably connected to a bracket one, the outer wall of the bracket one is fixedly connected to a bracket two, and one end of the bracket two is fixedly connected to a bracket three.

[0019] As a further description of the above technical solution:

[0020] The bracket 2 has a limiting groove 1 inside, and a sliding rod is provided at one end of the bracket 2. The sliding rod is slidably connected inside the limiting groove 1, and both ends of the sliding rod are rotatably connected to the top of the fixed block.

[0021] As a further description of the above technical solution:

[0022] A water storage tank is fixedly connected to the top of the support frame, a water outlet weir is fixedly connected to the outer wall of the water storage tank, a water inlet is fixedly connected to the outer wall of the water storage tank, and a water supply pipe is fixedly connected to one end of the water inlet.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the position is first determined on the ground, the support legs are placed, and the handle on the outer wall of the first housing is turned by hand to rotate the second housing, thereby driving the internally fitted limiting shaft to rotate. This causes the rotating shaft connected to one end of the limiting shaft inside the second housing to rotate, and finally drives the first bevel gear to rotate. Through gear meshing, the bushing and the lead screw fixed at its bottom are driven to rotate. The support leg has a fixed nut that meshes with the lead screw. When the lead screw rotates, the force between the lead screw and the nut lifts the first housing upward, thus achieving the function of adjusting the height of the modular quick-install photovoltaic bracket support legs. This solves the problem of instability on uneven roads caused by the inability to adjust the height of the support legs in traditional modular quick-install photovoltaic brackets, and improves the stability of the modular quick-install photovoltaic bracket.

[0025] 2. In this utility model, after the photovoltaic panels are installed on the bracket, due to the presence of dust in the air, a layer of dust often accumulates on the surface of the photovoltaic panels after long-term use, which leads to a decrease in power generation efficiency. A water storage tank is installed on the bracket. Clean water is transported through the water supply pipe and enters the water storage tank through the inlet. It overflows through the outlet weir. Because the photovoltaic panels are installed at an angle, the water flow will wash away the dust on the surface of the photovoltaic panels under the action of gravity, thus achieving the function of cleaning the dust on the surface of the photovoltaic panels. This solves the problem of the traditional modular quick-installation photovoltaic brackets causing a decrease in power generation efficiency due to the regular cleaning of the photovoltaic panel surface dust, and improves the practicality of the modular quick-installation photovoltaic brackets.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-2 The present invention provides an embodiment of a modular quick-install photovoltaic bracket, comprising a support plate 1, which is used to expand the force-bearing area and improve the installation stability of the bracket. A support leg 13 is fixedly connected to the top of the support plate 1, which is used to support the photovoltaic bracket. A nut 19 is fixedly connected inside the support leg 13. A housing 2 is sleeved on the outer wall of the support leg 13. A bushing 17 is fixedly connected to the outer wall of the housing 2. A rotating shaft 16 is rotatably connected inside the bushing 17. The bushing 17 makes the rotating shaft 16 rotate more smoothly. A bevel gear 15 is fixedly connected to the outer wall of the rotating shaft 16. A lifting component is provided on the outer wall of the bevel gear 15.

[0036] The lifting assembly includes a second bevel gear 18, the top gear of which is connected to the outer wall of a first bevel gear 15. A lead screw 20 is fixedly connected to the bottom of the second bevel gear 18. The first bevel gear 15 meshes with the second bevel gear 18. The rotation of the first bevel gear 15 drives the second bevel gear 18 and the lead screw 20 fixed at its bottom to rotate. At the same time, the lead screw 20 meshes with the lead screw nut 19. The force of the lead screw 20 rotating inside the lead screw nut 19 acts on the lead screw 20 and lifts the housing 2. A limit plate 21 is fixedly connected to the bottom of the lead screw 20. The limit plate 21 prevents the lead screw 20 from unwinding. The lead screw 20 is threaded inside the lead screw nut 19.

[0037] Reference Figures 1-6One end of the rotating shaft 16 is fixedly connected to a limiting shaft 25. A housing 2 4 is slidably connected to the outer wall of the limiting shaft 25. The housing 2 4 can slide along the limiting shaft 25, and when the housing 2 4 rotates, it drives the limiting shaft 25 to rotate. A limiting key 22 is fixedly connected to one side of the housing 2 4. A limiting groove 2 14 is opened on the outer wall of the housing 2 14. The limiting key 22 is slidably connected inside the limiting groove 2 14. When the housing 2 4 slides along the limiting shaft 25, the limiting key 22 is inserted into the limiting shaft 25 to lock the limiting shaft 25, thereby locking the housing 2 1 at a certain height. The outer shell 24 is fixedly connected to a connecting rod 23. A handle 24 is rotatably connected to the bottom of the connecting rod 23. Shaking the handle 24 causes the outer shell 24 to rotate via the connecting rod 23. The top of the outer shell 2 is fixedly connected to a top cover 5. A fixing block 6 is fixedly connected to the top of the top cover 5. The top cover 5 supports the fixing block 6 and seals the inside of the outer shell 2. A cover tile 28 is rotatably connected to the top of the fixing block 6. A connecting block 29 is fixedly connected to one side of the cover tile 28. A connecting block 20 is fixedly connected to one side of the fixing block 6. The connecting block 29 is bolted to the bracket. At the top of bracket 3, loosening the bolts allows the cover tile 28 to be opened. A bracket is installed between the cover tile 28 and the fixing block 6, and then the bolts are tightened. The top of the fixing block 6 is rotatably connected to bracket 3. A second bracket 7 is fixedly connected to the outer wall of bracket 3. A third bracket 9 is fixedly connected to one end of bracket 7. Brackets 3, 7, and 9 form a bracket for installing the photovoltaic panel. A limiting groove 10 is formed inside bracket 7. A sliding rod 12 is provided at one end of bracket 7, and the sliding rod 12 is slidably connected inside the limiting groove 10. The two ends of the sliding rod 12 rotate... The dynamic connection is on the top of the fixed block 6. When the housing 12 is raised, the bracket 2 7 can adapt to the change in the height of the housing 12 by sliding the slide rod 12. The top of the bracket 3 9 is fixedly connected to the water storage tank 8. The outer wall of the water storage tank 8 is fixedly connected to the water outlet weir 27. The outer wall of the water storage tank 8 is fixedly connected to the water inlet 26. One end of the water inlet 26 is fixedly connected to the water supply pipe 11. Water is transported to the inside of the water storage tank 8 through the water supply pipe 11 and the water inlet 26. The water overflows from the water outlet weir 27 and flows on the photovoltaic panel, washing away the dust on the surface of the photovoltaic panel.

[0038] Working principle: Place the outrigger 13 at a suitable position on the ground, crank the handle 24, and drive the housing 2 4 to rotate via the connecting rod 23. This, in turn, drives the limiting shaft 25 to rotate, which in turn causes the rotating shaft 16 to drive the bevel gear 15 to rotate. The bushing 17 meshes with the bevel gear 15. The rotation of the bevel gear 15 drives the bushing 17 to rotate, which in turn causes the lead screw 20 fixed at the top of the bushing 17 to rotate. The nut 19 fixed inside the outrigger 13 meshes with the lead screw 20. The reaction force generated by the rotation of the lead screw 20 inside the nut 19 lifts the housing 2. When the housing 2 rises to a suitable height, insert the limiting key 22 at one end of the housing 2 4 into the limiting groove 2 14 opened on the outer wall of the housing 2, thus locking the height of the housing 2.

[0039] Loosen the bolts and open the cover tile 28. Place bracket 3 and slide rod 12 between the cover tile 28 and the fixing block 6. Fasten the cover tile 28 and use bolts to fix the connecting block 29 and the cover tile 28. Use bracket 2 7, bracket 3 1, and bracket 3 9 to install and fix the photovoltaic panel. The bracket 2 7 can adapt to the height change of the shell 2 2 through the slide rod 12 connected internally, so that the bracket forms a certain angle. Water is delivered to the water storage tank 8 through the water supply pipe 11 and the water inlet 26. When there is enough water, it will overflow along the water outlet weir 27 and wash the dust on the surface of the photovoltaic panel under the action of gravity.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
