Description

Technical Field

[0001] This utility model relates to the field of photovoltaic mounting technology, specifically to a photovoltaic module mounting bracket with windproof and pressure-resistant design. Background Technology

[0002] Solar photovoltaic power generation is a green energy source that uses sunlight to deliver clean energy to humans. Photovoltaic modules absorb solar energy and convert it into other energy sources as needed. Installing photovoltaic modules requires a photovoltaic support structure. Since photovoltaic modules are usually installed in batches in flat and wide areas, they are easily exposed to direct natural winds, which necessitates the use of windproof photovoltaic support structures.

[0003] Currently, photovoltaic (PV) mounting systems are generally installed outdoors in open-air locations. The installation method typically involves using bolts to fix the columns to the base. In severe weather conditions, wind can easily cause the bolts to loosen, leading to the PV mounting system swaying and loosening under wind or external pressure. Prolonged swaying can damage the PV panels and affect their safety. Utility Model Content

[0004] This utility model proposes a photovoltaic module mounting bracket with windproof and pressure-resistant design to solve the problem that photovoltaic brackets fixed by bolts in the prior art are prone to loosening under wind force, thus affecting the installation stability.

[0005] The technical solution of this utility model is as follows: A photovoltaic module mounting frame with windproof and pressure-resistant design includes a photovoltaic frame, as well as columns, a base, a mounting bracket, and a fixing mechanism. A plurality of columns are fixedly installed at the bottom end of the photovoltaic frame. The base is installed on one side of the columns. A U-shaped mounting bracket is fixedly installed on the top side wall of the base. The columns extend into the mounting bracket. The shape of the columns matches the inner wall of the mounting bracket. The fixing mechanism is installed between the columns and the mounting bracket for installing and fixing the columns and the mounting bracket.

[0006] Preferably, the fixing mechanism includes a fixing port, a fixing groove, a first cavity, a positioning seat, and a positioning mechanism. The fixing port is provided at both ends of the side wall of the fixing frame. The fixing groove is perpendicular to the fixing port and is provided on the side wall of the fixing frame, communicating with the fixing port. The first cavity is provided within the column. A positioning port is provided on the side wall of the first cavity, aligned with the fixing port and the fixing groove. The positioning seat is slidably disposed within the first cavity. The positioning mechanism is disposed between the positioning seat and the fixing frame for positioning the positioning seat and the fixing frame.

[0007] Furthermore, the positioning mechanism includes a positioning column, a positioning block, and a moving mechanism. The positioning column is rotatably mounted on the side wall of the positioning seat located on one side of the positioning port. The positioning block is fixedly mounted on the end of the positioning column away from the positioning seat. The positioning block is adapted to the shape of the fixing port and the fixing groove, respectively. The moving mechanism is disposed between the positioning seat and the column and is used to drive the positioning seat to move within the first cavity.

[0008] Furthermore, the moving mechanism includes a positioning groove, a threaded rod, a first handwheel, and a limiting mechanism. The positioning groove is formed on the side wall of the first cavity, and a positioning disk is rotatably disposed within the positioning groove. The threaded rod is fixedly disposed on the positioning disk, and the end of the threaded rod away from the positioning disk is rotatably connected to the side wall of the first cavity. The threaded rod passes through the positioning seat through a threaded engagement. The first handwheel is rotatably disposed on the side wall of the column, and a drive rod is fixedly disposed between the first handwheel and the positioning disk. The limiting mechanism is disposed between the column and the positioning disk and is used to position the rotation angle of the positioning disk.

[0009] Furthermore, the limiting mechanism includes a limiting groove, a second cavity, a limiting frame, and a position adjustment mechanism. The limiting groove is formed on the side wall of the positioning disk, the second cavity is formed inside the column, and a limiting opening is formed on the side wall of the second cavity. The limiting opening is aligned with the limiting groove. The limiting frame is slidably disposed in the second cavity, and a limiting block is fixedly disposed on the side wall of the limiting frame. The limiting block extends through the limiting opening into the limiting groove. The position adjustment mechanism is disposed on the limiting frame and is used to drive the limiting frame to move within the second cavity.

[0010] Based on the above scheme, the position adjustment mechanism includes a damping spring, a cam, and a second handwheel. Multiple damping springs are fixedly arranged between the limiting frame and the side wall of the second cavity. The cam is rotatably arranged in the second cavity and contacts the side wall of the limiting frame. The second handwheel is rotatably arranged on the side wall of the column. A connecting rod is fixedly arranged between the second handwheel and the cam.

[0011] The working principle and beneficial effects of this utility model are as follows: 1. In this utility model, by setting up a fixing mechanism, after the column is inserted into the fixing frame, the positioning block can pass through the fixing opening. Then, the operator rotates the positioning block to align it with the fixing groove. Then, by rotating the first handwheel, the positioning plate and the threaded rod can be rotated. Thus, through the threaded engagement between the threaded rod and the positioning seat, the positioning seat, the positioning column, and the positioning block are moved, thereby allowing the positioning block to extend into the fixing groove and press against the bottom of the fixing groove, thus facilitating the installation and fixing between the column and the fixing frame. 2. In this utility model, by setting up a limiting mechanism, after the installation of the column is completed, the limiting block can be driven into the limiting groove by the elastic force of the damping spring. Thus, the positioning plate and the threaded rod can be positioned by the cooperation of the limiting block with the limiting port and the limiting groove respectively. At the same time, after being affected by wind or external impact, the damping spring will not deform significantly due to damping, thereby preventing the limiting block from coming out of the limiting groove, thus facilitating the improvement of the installation stability between the column and the fixing frame.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] like Figures 1-5 As shown, this embodiment proposes a photovoltaic module mounting frame with windproof and pressure-resistant design, including a photovoltaic frame 1, columns 2, base 3, mounting bracket 4, and fixing mechanism. Multiple columns 2 are fixedly installed at the bottom of the photovoltaic frame 1. The base 3 is installed on one side of the columns 2. A U-shaped mounting bracket 4 is fixedly installed on the top side wall of the base 3. The columns 2 extend into the mounting bracket 4, and the shape of the columns 2 and the inner wall of the mounting bracket 4 are adapted to each other. The fixing mechanism is installed between the columns 2 and the mounting bracket 4 for installing and fixing the columns 2 and the mounting bracket 4. The base 3 has an installation port. Specifically, the base 3 can be installed and fixed to the ground by passing an anchor rod through the installation port. When the soil bearing capacity is low, reinforced concrete piles can be driven into the ground and the base 3 can be pre-embedded in the concrete piles for fixing the base 3.

[0017] Reference Figures 1-4The fixing mechanism includes a fixing port 5, a fixing groove 6, a first cavity 7, a positioning seat 8, and a positioning mechanism. Fixing ports 5 are provided at both ends of the side wall of the fixing frame 4. The fixing groove 6 is perpendicular to the fixing port 5 and is located on the side wall of the fixing frame 4, communicating with the fixing port 5. The first cavity 7 is located inside the column 2. A positioning port is provided on the side wall of the first cavity 7, aligned with the fixing port 5 and the fixing groove 6. The positioning seat 8 is slidably disposed within the first cavity 7. The positioning mechanism is disposed between the positioning seat 8 and the fixing frame 4, used to position the positioning seat 8 and... Positioning is achieved between the fixed frames 4. The positioning mechanism includes a positioning post 9, a positioning block 10, and a moving mechanism. The positioning post 9 is rotatably mounted on the side wall of the positioning seat 8 located on one side of the positioning opening. The positioning block 10 is fixedly mounted on the end of the positioning post 9 away from the positioning seat 8. The positioning block 10 is adapted to the shape of the fixing opening 5 and the fixing groove 6, respectively. The moving mechanism is located between the positioning seat 8 and the column 2 and is used to drive the positioning seat 8 to move within the first cavity 7. The moving mechanism includes a positioning groove, a threaded rod 12, a first handwheel 13, and a limiting mechanism. The positioning groove is open... A positioning plate 11 is rotatably mounted in a positioning groove on the side wall of the first cavity 7. A threaded rod 12 is fixedly mounted on the positioning plate 11, with one end of the threaded rod 12 rotatably connected to the side wall of the first cavity 7. The threaded rod 12 passes through the positioning seat 8 via a threaded engagement. A first handwheel 13 is rotatably mounted on the side wall of the column 2. A drive rod is fixedly mounted between the first handwheel 13 and the positioning plate 11. A positioning mechanism is located between the column 2 and the positioning plate 11 to position the rotation angle of the positioning plate 11. Specifically, when the column... After the column 2 extends into the fixed frame 4, the positioning block 10 can pass through the fixed opening 5. Then, the operator rotates the positioning block 10 to align it with the fixed groove 6. Then, the rotation of the handwheel can drive the positioning disc 11 and the threaded rod 12 to rotate. Thus, the threaded rod 12 and the positioning seat 8 are moved by the threaded engagement of the threaded rod 12 with the positioning seat 8. This allows the positioning block 10 to extend into the fixed groove 6 and press against the bottom of the fixed groove 6, thereby facilitating the installation and fixation between the column 2 and the fixed frame 4.

[0018] Reference,3- Figure 5The limiting mechanism includes a limiting groove 14, a second cavity 15, a limiting frame 16, and a position adjustment mechanism. The limiting groove 14 is formed on the side wall of the positioning plate 11. The second cavity 15 is formed inside the column 2. A limiting opening is formed on the side wall of the second cavity 15, and the limiting opening is aligned with the limiting groove 14. The limiting frame 16 is slidably disposed in the second cavity 15. A limiting block 17 is fixedly disposed on the side wall of the limiting frame 16. The limiting block 17 extends through the limiting opening into the limiting groove 14. The position adjustment mechanism is disposed on the limiting frame 16 and is used to drive the limiting frame 16 to move within the second cavity 15. The position adjustment mechanism includes a damping spring 18, a cam 19, and a second handwheel 20. Multiple damping springs 18 are fixedly disposed between the limiting frame 16 and the side wall of the second cavity 15. The cam 19 is rotatably disposed in the second cavity 15 and contacts the side wall of the limiting frame 16. The second handwheel 20 is rotatably disposed on the side wall of the column 2. A connecting rod is fixedly disposed between the second handwheel 20 and the cam 19. Specifically, after the column 2 is installed, the limiting block 17 can be driven into the limiting groove 14 by the elastic force of the damping spring 18. Thus, the positioning plate 11 and the threaded rod 12 can be positioned by the cooperation of the limiting block 17 with the limiting port and the limiting groove 14 respectively. At the same time, after being affected by wind or external impact, the damping spring 18 will not deform significantly due to damping, thereby preventing the limiting block 17 from falling out of the limiting groove 14, thus facilitating the improvement of the installation stability between the column 2 and the fixing frame 4.

[0019] In this embodiment, during use, after the operator inserts the column 2 into the fixing frame 4, the positioning block 10 can pass through the fixing opening 5. Then, the operator rotates the positioning block 10 to align it with the fixing groove 6. Next, the operator rotates the second handwheel 20, which drives the connecting rod and the cam 19 to rotate. This causes the limiting block 17 to disengage from the limiting groove 14 through the compression of the limiting frame 16 by the cam 19. Then, the operator rotates the first handwheel 13, which drives the positioning plate 11 and the threaded rod 12 to rotate. This causes the positioning seat 8, the positioning column 9, and the positioning block to rotate through the threaded engagement between the threaded rod 12 and the positioning seat 8. The positioning block 10 is moved so that it extends into the fixing groove 6 and presses against the bottom of the fixing groove 6, thus facilitating the installation and fixing between the column 2 and the fixing frame 4. Afterwards, the operator releases the second handwheel 20, and the limiting block 17 is driven into the limiting groove 14 by the elastic force of the damping spring 18. Thus, the positioning plate 11 and the threaded rod 12 are positioned by the cooperation of the limiting port and the limiting groove 14 respectively. At the same time, after being affected by wind or external impact, the damping spring 18 will not deform significantly due to damping, thus preventing the limiting block 17 from coming out of the limiting groove 14, thereby improving the installation stability between the column 2 and the fixing frame 4.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
