Description

Technical Field

[0001] This application belongs to the field of photovoltaic panel installation technology, specifically a photovoltaic module quick installation and angle adjustment bracket. Background Technology

[0002] Photovoltaic modules are the core devices that convert solar energy into electrical energy. They are typically composed of multiple solar cells connected in series or parallel, and are externally fitted with tempered glass, EVA film, backsheet, and aluminum alloy frame. They also include a junction box. Their working principle is based on the photovoltaic effect of semiconductors. When sunlight shines on the cells, photons excite electrons to transition and form an electric current, ultimately outputting direct current. Depending on the application scenario, they can be divided into conventional fixed modules, foldable modules, flexible modules, etc. They are characterized by being clean and pollution-free and generating electricity sustainably, and are widely used in centralized photovoltaic power plants, distributed rooftop photovoltaic systems, and portable power generation equipment.

[0003] For example, the utility model patent with announcement number CN218940987U discloses a quick-installation bracket for fixing photovoltaic modules, which belongs to the field of photovoltaic panel installation technology. The quick-installation bracket for fixing photovoltaic modules includes a bottom support component, a clamping installation component, and a solar photovoltaic panel. The bottom support component includes a bottom frame plate, a support, a connecting rod, and positioning bolts. In this utility model, two people lift the bottom sides of the solar photovoltaic panel, pre-clamp the top of the solar photovoltaic panel under the upper clamping plate, and press it upward against the upper clamping plate so that the elastic support part is in a compressed state. Then, the bottom of the solar photovoltaic panel is clamped above the lower clamping plate. The elasticity of the elastic support part is used to quickly clamp and install the solar photovoltaic panel between the lower clamping plate and the upper clamping plate.

[0004] However, in actual use, it was discovered that the device achieves rapid installation of solar photovoltaic panels by using a snap-on installation component. However, due to the use of elastic support to press and fix the solar photovoltaic panel, the overall stability of the solar photovoltaic panel is not good during subsequent use. At the same time, the overall adaptability of the clamping installation component is poor. When the size of the solar photovoltaic panel to be installed changes, the clamping installation component cannot adapt well to solar photovoltaic panels of different sizes to achieve stable and fast installation. Therefore, a fast installation and angle adjustment bracket for photovoltaic modules is provided. Utility Model Content

[0005] The purpose of this application is to provide a fast installation and angle adjustment bracket for photovoltaic modules in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A photovoltaic module quick installation and angle adjustment bracket includes a photovoltaic main frame. Multiple aluminum profile brackets are installed in an array at equal intervals on the front side of the photovoltaic main frame. Each of the multiple aluminum profile brackets has a limiting groove along its length on its front side. A T-shaped nut is slidably adapted inside the limiting groove. A connecting plate is fixedly connected to the front side of the T-shaped nut. A Z-shaped fixing plate is fixedly installed on the side of the connecting plate away from the T-shaped nut. A circular through hole is opened in the horizontal section of the Z-shaped fixing plate. An internal hexagon bolt is movably inserted in the circular through hole. A threaded hole adapted to the internal hexagon bolt is opened on the front side of the T-shaped nut. The screw end of the internal hexagon bolt is threaded into the threaded hole.

[0008] In a preferred embodiment, both ends of the aluminum profile bracket are detachably fixed to the front side of the photovoltaic main frame by countersunk bolts, and the distance between two adjacent aluminum profile brackets is not less than the width of the photovoltaic module.

[0009] In a preferred embodiment, the connecting plate and the Z-shaped fixing plate are integrally formed, and anti-slip rubber pads are attached to the inner sides of each symmetrically arranged Z-shaped fixing plate.

[0010] In a preferred embodiment, the cross-section of the limiting groove is T-shaped, and a sliding gap of 0.5-1mm is reserved between the outer peripheral surface of the T-shaped nut and the inner wall of the limiting groove.

[0011] In a preferred embodiment, a base plate is fixedly installed at the bottom end of the main support rod, and the base plate has a plurality of expansion bolt holes.

[0012] In a preferred embodiment, the length of the socket head cap screw is greater than the thickness of the horizontal section of the Z-shaped fixing plate, and a flat washer and a spring washer are provided between the head of the socket head cap screw and the Z-shaped fixing plate.

[0013] In a preferred embodiment, the drive motor is a servo motor with a self-locking function, and a dust cover is fixedly fitted on the outer wall of the connecting housing corresponding to the connection part between the worm and the drive motor.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: 1. In this application, due to the adoption of the above-mentioned solution, the user first slides the T-nut along the limiting groove of the aluminum profile bracket according to the size of the photovoltaic module, adjusts the spacing of the symmetrical Z-shaped fixing plates to match the edge of the module, and then attaches the two sides of the module to the inner side of the fixing plate. Subsequently, the user passes the hexagonal bolt through the circular through hole of the fixing plate and screws it into the threaded hole of the T-nut.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] refer to Figures 1-4 As shown, a photovoltaic module quick-installation and angle-adjustable bracket includes a photovoltaic main frame 1. Multiple aluminum profile brackets 2 are evenly spaced and arrayed on the front side of the photovoltaic main frame 1. Both ends of the aluminum profile brackets 2 are detachably fixed to the front side of the photovoltaic main frame 1 using countersunk bolts. The spacing between two adjacent aluminum profile brackets 2 is not less than the width of the photovoltaic module. The countersunk bolts allow for a detachable connection between the aluminum profile brackets 2 and the photovoltaic main frame 1, facilitating future replacement or maintenance of the aluminum profile brackets 2. The design of spacing not less than the width of the photovoltaic module prevents interference between the photovoltaic module and adjacent aluminum profile brackets 2 during installation, ensuring the photovoltaic module can be stably placed on the bracket and improving installation adaptability.

[0019] refer to Figures 1-4 As shown, each of the multiple aluminum profile brackets 2 has a limiting groove 3 along its length on its front side. A T-nut 4 is slidably fitted inside the limiting groove 3. The limiting groove 3 has a T-shaped cross-section, and a sliding gap of 0.5-1mm is reserved between the outer circumference of the T-nut 4 and the inner wall of the limiting groove 3. By fitting the T-shaped limiting groove 3 with the T-nut 4, the T-nut 4 can be prevented from falling out of the groove, ensuring connection stability. The 0.5-1mm sliding gap can prevent the T-nut 4 from being stuck and reduce shaking during the sliding process, ensuring that the T-nut 4 can be accurately adjusted along the length of the aluminum profile bracket 2 to adapt to the installation hole requirements of photovoltaic modules of different sizes.

[0020] refer to Figures 1-4As shown, a connecting plate 5 is fixedly connected to the front side of the T-nut 4. A Z-shaped fixing plate 6 is fixedly installed on the side of the connecting plate 5 away from the T-nut 4. The connecting plate 5 and the Z-shaped fixing plate 6 are integrally formed. Anti-slip rubber pads are attached to the inner sides of each symmetrically arranged Z-shaped fixing plate 6. A circular through hole 7 is opened in the horizontal section of the Z-shaped fixing plate 6. An internal hexagon bolt 8 is movably inserted in the circular through hole 7. A threaded hole 9 that matches the internal hexagon bolt 8 is opened on the front side of the T-nut 4. The screw end of the internal hexagon bolt 8 is threaded into the threaded hole 9. The screw length of the internal hexagon bolt 8 is greater than the thickness of the horizontal section of the Z-shaped fixing plate 6, and the head of the internal hexagon bolt 8 is connected to the Z-shaped fixing plate 6. Flat washers and spring washers are installed between the fixing plates 6. The integrally molded connecting plate 5 and the Z-shaped fixing plate 6 can improve the structural strength and prevent breakage during long-term use. The anti-slip rubber pad can increase the friction between the Z-shaped fixing plate 6 and the photovoltaic module, prevent the photovoltaic module from sliding and shifting, and at the same time play a buffering role, reducing damage to the edges of the photovoltaic module due to compression. The screw length is greater than the thickness of the horizontal section of the Z-shaped fixing plate, which can ensure that the internal hex bolt 8 can be fully screwed into the threaded hole 9. With the flat washers and spring washers, the anti-loosening effect of the bolt connection can be enhanced, avoiding bolt loosening caused by long-term vibration and improving the stability of the photovoltaic module installation.

[0021] refer to Figures 1-4 As shown, a connecting bracket 10 is fixedly installed on the rear side of the photovoltaic main frame 1, and a main support rod 11 is provided on the rear side of the photovoltaic main frame 1. A base plate 19 is fixedly installed at the bottom end of the main support rod 11, and multiple expansion bolt holes are provided on the base plate 19. By cooperating with the base plate 19 and the expansion bolt holes, the main support rod 11 can be firmly fixed to the ground or the installation foundation by the expansion bolts, which increases the contact area between the bracket and the ground, reduces the pressure of the bracket on the ground, and at the same time prevents the bracket from tipping over due to external forces such as wind and vibration, thereby improving the overall support stability of the bracket.

[0022] refer to Figures 1-4As shown, a U-shaped mounting plate 12 is provided at the top of the main support rod 11. A circular mounting base 13 is fixedly installed between the inner sidewalls of the U-shaped mounting plate 12. An angle adjustment rod 14 is rotatably inserted through the middle of the circular mounting base 13 via a bearing. The two ends of the angle adjustment rod 14 are respectively fixedly connected to the rear end of the connecting bracket 10 on the corresponding side. A worm gear 15 is fixedly sleeved on the outer circumferential surface of the angle adjustment rod 14 inside the circular mounting base 13. A connecting housing 16 is fixedly installed on the outer circumferential surface of the circular mounting base 13 near the bottom. A worm 17 is rotatably connected inside the connecting housing 16. The worm 17 meshes with the worm gear 15 for transmission. A drive motor 18 is fixedly installed on one side of the connecting housing 16. The output shaft of the drive motor 18 is coaxially fixed with one end of the worm 17. The drive motor 18 is a servo motor with a self-locking function, and the outer sidewall of the connecting housing 16 is corresponding to... A dust cover is fixedly fitted at the connection between the worm gear 17 and the drive motor 18. The meshing transmission between the worm wheel 15 and the worm gear 17 has a speed reduction and torque increase effect, which allows the drive motor 18 to drive the angle adjustment rod 14 to rotate smoothly with a small power, realizing the fine adjustment of the angle of the photovoltaic main frame 1. The servo motor with self-locking function can automatically lock after the angle adjustment is completed to prevent the angle adjustment rod 14 from reversing due to gravity or external force, ensuring the stability of the photovoltaic module angle. The dust cover can block dust and rainwater from entering the interior of the connecting housing 16, and prevent the worm gear 17 and worm wheel 15 from being stuck or corroded by impurities, which would affect the transmission accuracy. At the same time, the top of the main support rod 11 is provided with a drive mechanism composed of the same worm wheel and worm, which is fixed to the bottom surface of the U-shaped mounting plate 12. In this way, the position adjustment of the photovoltaic main frame 1 can be realized, thereby improving adaptability.

[0023] The implementation principle of this application's embodiment of a photovoltaic module quick installation and angle adjustment bracket is as follows: First, the user adjusts the distance between the two sets of symmetrical Z-shaped fixing plates 6 according to the dimensions of the photovoltaic module to be installed. Then, the user slides the T-nut 4 along the limiting groove 3 of the aluminum profile bracket 2 to match the edge of the photovoltaic module. The two sides of the photovoltaic module are then attached to the inner sides of the two sets of Z-shaped fixing plates 6. At this time, the bottom of the photovoltaic module is supported by the aluminum profile bracket 2. Next, the user inserts the hexagonal socket head cap bolt 8 through the circular through hole 7 of the Z-shaped fixing plate 6 and screws it into the threaded hole 9 of the T-nut 4. During the tightening process, the flat washer and spring washer are gradually compressed until the Z-shaped fixing plate 6 firmly clamps the photovoltaic module, completing the quick installation of a single photovoltaic module. If disassembly is required, simply loosen the hexagonal socket head cap bolt 8 in the reverse direction to remove the photovoltaic module. No complicated disassembly steps are needed. When adjusting the tilt angle of the photovoltaic module according to the angle of solar irradiation, the servo motor 18 with self-locking function is activated. The output shaft of the drive motor 18 drives the worm gear 17 to rotate within the connecting housing 16. The worm gear 17 meshes with the worm wheel 15 on the angle adjustment rod 14. Through deceleration and torque increase transmission, the angle adjustment rod 14 is driven to rotate around the bearing in the circular fixed seat 13. The two ends of the angle adjustment rod 14 are fixed to the connecting bracket 10 on the rear side of the photovoltaic main frame 1. Therefore, when the rod rotates, it will drive the photovoltaic main frame 1 to rotate around the axis of the angle adjustment rod 14, thereby adjusting the tilt angle of the photovoltaic module on the front side of the photovoltaic main frame 1. This device enables quick installation and removal of photovoltaic modules through sliding adjustment and bolt clamping, and achieves precise angle adjustment through worm gear transmission and servo motor self-locking. It takes into account both installation convenience and usage stability, and adapts to the installation needs of photovoltaic modules in different scenarios.
