[0022] Specifically, the outer surface of the fixing rod 11 is rotatably connected with a clamping plate 12 and a clamping plate 2 13 , and the clamping plate 12 and the clamping plate 2 13 are symmetrically arranged on the lower side of the photovoltaic panel body 5 in an arc shape.

[0023] The thread groove on the outer surface of the threaded rod 6 is a bidirectional thread groove. A top block 9 is provided on the lower side of the first clamping plate 12 and the second clamping plate 13. The two groups of connecting rods 8 on the same side are rotatably connected to the corresponding top blocks 9.

[0024] A slide groove 14 is provided on the lower end surface of the first clamping plate 12 and the second clamping plate 13 , and a transmission column 15 is fixedly mounted on the upper end surface of the top block 9 , and the upper end of the transmission column 15 is slidably connected to the slide groove 14 .

[0025] Specifically, a sleeve 10 is fixedly installed at the end of the top block 9, a transmission shaft 18 is slidably connected to the end of the sleeve 10, a vertical rod 19 is fixedly installed at the end of the transmission shaft 18, a spring 20 is fixedly installed between the vertical rod 19 and the sleeve 10, and the spring 20 is sleeved on the outer surface of the transmission shaft 18.

[0026] The ends of the first and second clamping plates 12 and 13 are both provided with slots 16, and a fixed shaft 17 is fixedly installed inside the slots 16. A slide rail 21 is provided on the front end surface of the vertical rod 19, and the fixed shaft 17 is slidably connected to the slide rail 21. A storage tube 22 is fixedly installed at the end of the vertical rod 19.

[0027] When the photovoltaic panel body 5 needs to be installed, the photovoltaic panel body 5 is placed on the upper part of the clamping plate 1 12 and the clamping plate 2 13, and then the motor 28 is started to rotate the threaded rod 6. The thread groove on the outer surface of the threaded rod 6 is a bidirectional thread groove. Therefore, the two groups of threaded sleeves 7 connected by the spiral transmission on the outer surface of the threaded rod 6 will be synchronously displaced to both sides, and each group of threaded sleeves 7 will carry two groups of connecting rods 8 to displace, and the two groups of connecting rods 8 on the same side are rotatably connected to the corresponding group of top blocks 9. Therefore, under the action of the threaded sleeves 7 and the connecting rods 8, the two groups of top blocks 9 will be driven and carry one The transmission column 15 of the two groups is displaced toward the center, and the transmission columns 15 of the two groups are slidably connected with the slide grooves 14 provided on the lower end surfaces of the clamp plate 12 and the clamp plate 2 13 respectively. The clamp plate 12 and the clamp plate 2 13 are both arranged in an arc shape for the arc-shaped photovoltaic panel body 5. Therefore, with the displacement of the transmission column 15, the clamp plate 12 and the clamp plate 2 13 will be deflected around the fixing rod 11 and synchronously deflected toward the photovoltaic panel body 5 to preliminarily fix the photovoltaic panel body 5. The upper end surfaces of the clamp plate 12 and the clamp plate 2 13 are fixedly installed with anti-slip rubber pads corresponding to the photovoltaic panel body 5.

[0028] Specifically, the fixing mechanism also includes an extension piece arranged at the end of the vertical rod 19, and the extension piece includes a block 23 slidably connected to the inside of the storage tube 22. A guide cavity 24 is opened inside the vertical rod 19, and a memory alloy 25 is slidably connected to the inside of the guide cavity 24.

[0029] One end of the memory alloy 25 extends into the interior of the receiving tube 22 and is fixedly connected to the clamping block 23 , and the other end of the memory alloy 25 extends into the interior of the slide rail 21 and is fixedly connected to the fixed shaft 17 .

[0030] Two groups of extension pieces are provided correspondingly and symmetrically, and a protective pad is fixedly mounted on the lower end surface of the clamping block 23 .

[0031] At the same time, the combination of the sliding sleeve 10, the transmission shaft 18, the vertical rod 19 and the spring 20 fixedly installed at the end of the top block 9 synchronously approaches and fits tightly to the photovoltaic panel body 5 for clamping and fixing. When the vertical rod 19 approaches the photovoltaic panel body 5, the fixed shaft 17 inside the groove 16 is affected by the deflection of the clamping plate 12 and the clamping plate 2 13 and slides up inside the slide rail 21, thereby lifting the memory alloy 25, so that the memory alloy 25 extends from the inside of the guide cavity 24, and then the clamping block 23 extends from the inside of the storage tube 22, thereby increasing the clamping firmness of the buckle assembly to the photovoltaic panel body 5.

[0032] Specifically, the fixing mechanism also includes clamping members arranged on both sides of the photovoltaic panel body 5, and the clamping members include a transmission plate 26 slidably connected to the outer surface of the fixing rod 11, and the lower end of the transmission plate 26 is spirally connected to the threaded rod 6. The end of the transmission plate 26 is fixedly installed with a side plate 27, and two groups of clamping members are correspondingly arranged.

[0033] Both ends of the threaded rod 6 are respectively connected with transmission plates 26 by screw drive. The two groups of transmission plates 26 are both slidably connected to the fixed rod 11. Therefore, under the drive of the threaded rod 6, the two groups of transmission plates 26 move synchronously towards the photovoltaic panel main body 5 and clamp and fix the photovoltaic panel main body 5. When it is necessary to release the fixation for disassembly, the motor 28 is driven to reverse the threaded rod 6, so that the above transmission structure can be reversed, thereby releasing the fixation of the photovoltaic panel main body 5.

[0034] In actual application of existing equipment, the traditional bolt fixation method is still used to install photovoltaic panels. This method not only has cumbersome procedures and complex installation, but also greatly limits the efficiency of quick installation and disassembly. Especially when it is necessary to disassemble and repair the solar panel, this complex disassembly and assembly process significantly prolongs the maintenance time, affects the overall work efficiency and operation convenience. The cumbersome fixation method has become a bottleneck restricting the flexibility of the system and the maintenance response speed, reducing the efficiency and convenience of the operation and maintenance work. Therefore, in this solution, a fixation mechanism is set to quickly install the photovoltaic panel main body 5. First, the photovoltaic panel is clamped and preliminarily fixed by the buckle assembly, and the extension piece is driven synchronously to strengthen the fixation effect of the buckle assembly on the photovoltaic panel main body 5. At the same time, a clamping piece is added in the horizontal direction to cooperate with the buckle assembly to fix the photovoltaic panel main body 5 in all directions, which not only improves the installation efficiency but also improves the fixation effect.

[0035] Usage method: When it is necessary to install the photovoltaic panel main body 5, place the photovoltaic panel main body 5 on the upper parts of the clamping plate 12 and the clamping plate 13. Then start the motor 28 to make the threaded rod 6 rotate. The thread grooves on the outer surface of the threaded rod 6 are double-thread grooves. Therefore, the two groups of threaded sleeves 7 spirally connected to the outer surface of the threaded rod 6 will move synchronously to both sides. Each group of threaded sleeves 7 will drive two groups of connecting rods 8 to move. The two groups of connecting rods 8 on the same side are both rotatably connected to a corresponding top block 9. Therefore, under the action of the threaded sleeve 7 and the connecting rod 8, the two groups of top blocks 9 will be driven to carry a transmission column 15 towards the center. The two transmission columns 15 are respectively slidably connected to the sliding grooves 14 opened on the lower end surfaces of the clamping plate 12 and the clamping plate 13. The clamping plate 12 and the clamping plate 13 are both arc-shaped for the arc-shaped photovoltaic panel main body 5. Therefore, as the transmission column 15 moves, the clamping plate 12 and the clamping plate 13 will both deflect around the fixed rod 11 and deflect towards the photovoltaic panel main body 5 synchronously to preliminarily fix the photovoltaic panel main body 5. Anti-slip rubber pads are fixedly installed on the upper end surfaces of the clamping plate 12 and the clamping plate 13 corresponding to the photovoltaic panel main body 5; Meanwhile, the combination of the sliding sleeve 10, the transmission shaft 18, the vertical rod 19 and the spring 20 fixedly installed at the end of the top block 9 moves closer to and presses against the main body 5 of the photovoltaic panel for clamping and fixing. When the vertical rod 19 moves closer to the main body 5 of the photovoltaic panel, the fixed shaft 17 inside the notch 16 will slide upward inside the slide rail 21 under the influence of the deflection of the first clamping plate 12 and the second clamping plate 13, thereby jacking up the shape memory alloy 25, causing the shape memory alloy 25 to extend from the inside of the guiding cavity 24, and further causing the latch 23 to extend from the inside of the receiving tube 22, increasing the clamping firmness of the snap assembly to the main body 5 of the photovoltaic panel; Secondly, transmission plates 26 are respectively screwed and driven at both ends of the threaded rod 6. The two groups of transmission plates 26 are both slidably connected to the fixed rod 11. Therefore, under the drive of the threaded rod 6, the two groups of transmission plates 26 move synchronously towards the main body 5 of the photovoltaic panel and clamp and fix the main body 5 of the photovoltaic panel. When it is necessary to release the fixation for disassembly, the motor 28 is driven to reverse the threaded rod 6, so that the above transmission structure can be reversed, thereby releasing the fixation of the main body 5 of the photovoltaic panel.

[0036] The above is only the preferred specific implementation mode of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
