Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a highly adjustable and stable photovoltaic support. Background Technology

[0002] Photovoltaic (PV) mounting systems are a crucial component of solar photovoltaic (PV) power generation systems. They are primarily used to support and secure PV modules, ensuring they receive solar radiation at the optimal angle to maximize power generation efficiency. The installation of solar panels requires bolts for fixing, with pre-drilled slots inside the mounting system to mate with the bolts. After installation, the solar panels need to face the sun, necessitating that the PV mounting system be able to maintain a fixed orientation relative to the ground. However, in complex environments, there is often insufficient installation space for adjusting and installing the PV mounting system.

[0003] A search revealed that patent CN221227431U discloses a height-adjustable solar photovoltaic bracket, which uses a handwheel to drive a worm gear, which in turn drives a screw to raise or lower a sliding rod. However, this height adjustment method relies on manual rotation of the handwheel. Once the photovoltaic panels are installed on top of the bracket, the weight of the panels and the sliding rod itself acts on the screw, resulting in high resistance to the handwheel's rotation and making adjustment inconvenient and labor-intensive. Secondly, once the sliding rod is raised, the center of gravity also rises, reducing its wind resistance. Furthermore, this bracket only allows for horizontal angle adjustment and cannot adjust the pitch angle of the installed photovoltaic panels, thus requiring further improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly adjustable and stable photovoltaic support.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a height-adjustable and stable photovoltaic support, comprising a column, the column being a square column, with a partition fixed at the bottom of the column, a square sliding rod slidably connected inside the column and above the partition, a reduction motor fixed on the lower surface of the partition, and a lead screw fixed at the top output end of the reduction motor, the lead screw passing through the sliding rod and rotatably connected to the sliding rod via a thread, a cross base plate fixed at the bottom of the column, and a tensioning assembly connected to the top of the sliding rod at each of the four corners of the upper surface of the cross base plate, the top rod of the sliding rod being rotatably connected to a disc via a bearing, and an L-shaped plate fixed on the upper surface of the disc, the top of the L-shaped plate having a shaft hole, and a threaded shaft rotatably connected inside the shaft hole, a swing rod fixed at one end of the threaded shaft, and a mounting plate fixed at the other end of the swing rod.

[0006] Furthermore, both the mounting plate and the cross-shaped base plate are provided with mounting holes.

[0007] Furthermore, the slide bar has a hollow interior, and the lead screw and the partition are rotatably connected by a sealed bearing.

[0008] Furthermore, the traction assembly includes a circular tube hinged to the upper surface of the cross base plate, a connecting rod slidably connected inside the circular tube, the top end of the connecting rod being hinged to the outer surface of the sliding rod, and a first fastening bolt being threadedly connected to the side wall of the top end of the circular tube.

[0009] Furthermore, a second fastening bolt is connected through the side of the disk and rotated via a thread.

[0010] Furthermore, a nut is rotatably connected to the end of the threaded shaft away from the rocker arm via a thread, and the nut is in contact with the surface of the L-shaped plate.

[0011] Furthermore, an annular top cover is fixed to the top of the column by bolts, and a sliding rod passes through the middle of the top cover. A sealing ring is fixed to the inner wall of the top cover, and the surface of the sliding rod is in contact with the sealing ring.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model provides a height-adjustable and stable photovoltaic support structure, which includes a column, a sliding rod, a geared motor, a lead screw, a cross base plate, a traction assembly, and a mounting plate. The geared motor drives the lead screw to rotate, and the lead screw then drives the sliding rod to slide up and down along the column, thereby adjusting the height of the top mounting plate. The motor-driven method is more stable and labor-saving. After the height is raised or lowered, the traction assembly further restricts the sliding rod, improving wind resistance and making the entire support structure more stable.

[0014] 2. In use, this utility model provides a height-adjustable and stable photovoltaic bracket, which includes a disc, an L-shaped plate, a threaded shaft, and a mounting plate. After the photovoltaic panel is fixed on the mounting plate, the horizontal angle can be adjusted by rotating the disc horizontally, and the pitch angle of the mounting plate and the photovoltaic panel can be adjusted by rotating the threaded shaft on the top of the L-shaped plate, making the installation of the photovoltaic panel more flexible.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a highly adjustable and stable photovoltaic support includes a column 1, which is a square column. A partition 3 is fixed to the bottom of the column 1. A square slide rod 2 is slidably connected inside the column 1 and above the partition 3. A reduction motor 4 is fixed to the lower surface of the partition 3. A lead screw 5 is fixed to the top output end of the reduction motor 4. The lead screw 5 passes through the slide rod 2 and is rotatably connected to the slide rod 2 by a thread. A cross base plate 6 is fixed to the bottom of the column 1. A tensioning assembly 7 is connected to the top of the slide rod 2 at each of the four corners of the upper surface of the cross base plate 6. A disc 8 is rotatably connected to the top of the slide rod 2 by a bearing. An L-shaped plate 9 is fixed to the upper surface of the disc 8. A shaft hole is opened at the top of the L-shaped plate 9. A threaded shaft 10 is rotatably connected inside the shaft hole. A swing rod 11 is fixed to one end of the threaded shaft 10, and a mounting plate 12 is fixed to the other end of the swing rod 11.

[0023] Mounting holes are provided on both the mounting plate 12 and the cross-shaped base plate 6.

[0024] In this embodiment, the mounting holes on the mounting plate 12 are used to install photovoltaic panels, and the mounting holes on the cross base plate 6 are used to fix the cross base plate 6 to the ground, thereby realizing the fixed installation of the column 1.

[0025] The slide bar 2 has a hollow interior, and the lead screw 5 and the partition plate 3 are rotatably connected by a sealed bearing.

[0026] By setting the partition 3, the space at the bottom of the column 1 is enclosed, thus protecting the geared motor 4. In this embodiment, the geared motor 4 is an NMRV050 motor. The geared motor 4 drives the lead screw 5 to rotate forward or reverse, and the lead screw 5 drives the slide bar 2 to rise or fall along the column 1, thereby driving the mounting plate 12 to rise and fall.

[0027] In this embodiment, the control line and power line of the geared motor 4 pass through the side wall of the column 1 and are controlled by an external controller, and the control line, power line and column 1 are sealed together.

[0028] The traction assembly 7 includes a circular tube 71 hinged to the upper surface of the cross base plate 6. A connecting rod 72 is slidably connected inside the circular tube 71. The top end of the connecting rod 72 is hinged to the outer surface of the slide rod 2. A first fastening bolt 73 is threaded through the side wall of the top end of the circular tube 71 and rotatably connected to it.

[0029] When raising and lowering the slide bar 2 and the mounting plate 12, loosen the first fastening bolt 73 on each round tube 71. As the slide bar 2 rises and falls, the connecting rod 72 will slide along the round tube 71. After the raising and lowering adjustment is completed, tighten each first fastening bolt 73.

[0030] The second fastening bolt 14 is threaded through the side of the disc 8 and rotates through it.

[0031] The horizontal angle of the mounting plate 12 can be adjusted by rotating the disc 8. After adjustment, tighten the second fastening bolt 14 to press the upper surface of the slide rod 2, thereby fixing the disc 8.

[0032] The end of the threaded shaft 10 away from the rocker arm 11 is connected to a nut 13 by a threaded rotation, and the nut 13 is in contact with the surface of the L-shaped plate 9.

[0033] In this embodiment, the threaded shaft 10 rotates normally with the shaft hole. Therefore, the swing rod 11 and the mounting plate 12 can rotate inside the shaft hole through the threaded shaft 10 to adjust the pitch angle of the photovoltaic panel on the surface of the mounting plate 12. After the adjustment is completed, the nut 13 is tightened to press against the surface of the L-shaped plate 9, thereby fixing the threaded shaft 10 and the swing rod 11.

[0034] The top of the column 1 is fixed with an annular top cover 15 by bolts, and the slide rod 2 passes through the middle of the top cover 15. A sealing ring 16 is fixed on the inner wall of the top cover 15, and the surface of the slide rod 2 is in contact with the sealing ring 16.

[0035] The sealing ring 16 can increase the sealing of the top of the column 1 and prevent rainwater from entering the interior of the column 1.

[0036] Working principle: When it is necessary to adjust the height of the slide bar 2 and the mounting plate 12, first loosen the first fastening bolt 73 on each round tube 71, then start the reduction motor 4 to drive the slide bar 2 and the mounting plate 12 to rise or fall. After adjustment, tighten each first fastening bolt 73, and use the traction assembly 7 to increase the stability of the slide bar 2. Horizontally rotating the disc 8 can change the horizontal angle of the photovoltaic panel on the surface of the mounting plate 12, and rotating the threaded shaft 10 can change the pitch angle of the photovoltaic panel on the surface of the mounting plate 12.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
