DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 , the utility model provides a technical solution:

[0023] In this technical solution, an auxiliary device for splicing photovoltaic brackets includes a clamping plate 1, and clamps 2 are inserted and installed on both the left and right sides of the clamping plate 1, and the clamps 2 are sleeved on the outside of the external photovoltaic bracket;

[0024] The cross-section of the plywood 1 is U-shaped, and a sliding groove 3 is provided on the lower wall of the plywood 1. A lower plywood 4 is slidably installed in the sliding groove 3. Threaded holes 5 are provided on the front and rear sides of the sliding groove 3. A through hole 6 is provided on the lower wall of the lower plywood 4. There are two through holes 6. Bolts 7 are inserted into the two through holes 6. The two bolts 7 correspond to the positions of the two threaded holes 5 respectively. The bolts 7 can be screwed into the threaded holes 5. A shielding cover 8 is installed on the lower wall of the sliding groove 3. The shielding cover 8 is connected to the outside of the bolt 7. The lower wall of the shielding cover 8 can fit with the upper wall of the lower plywood;

[0025] The clamping plate 1 and the lower clamping plate 4 can clamp the external photovoltaic panel;

[0026] In this technical solution, the overall clamping plate 1 is installed on the external photovoltaic bracket through the clamping hoop 2, and then the clamping plate 1 is fixed by tightening the fastening nut 11 on the clamping hoop 2. After the clamping plate 1 is fixed, the bolt 7 under the lower clamping plate 4 can be rotated to screw the bolt 7 into the threaded hole 5, and the lower clamping plate 4 can be driven to move upward continuously, so that the photovoltaic panel to be installed on the external photovoltaic bracket can be spliced ​​and fixed through the cooperation between the clamping plate 1 and the lower clamping plate 4;

[0027] Because the lower splint 4 in this article is movable, the device can be applied to photovoltaic panels of different models, thereby improving the applicability of the device. In addition, a shielding cover 8 is provided on the outside of the bolt 7. Through the setting of the shielding cover 8, the bolt 7 can be shielded and protected to avoid contact with external rainwater, thereby preventing rust and affecting the subsequent disassembly.

[0028] In some technical solutions, the shielding cover 8 includes a main cylinder 81, a sub-cylinder 82, a spring 83 and a sealing ring 84. The main cylinder 81 is inserted and installed on the lower wall of the sliding groove 3. The sub-cylinder 82 is inserted and installed on the lower wall of the main cylinder 81. The sub-cylinder 82 can slide in the main cylinder 81. A spring 83 is installed in the main cylinder 81. The spring 83 is connected to the end of the sub-cylinder 82. A sealing ring 84 is installed on one end of the sub-cylinder 82 located outside the main cylinder 81. The sealing ring 84 is in contact with the upper wall of the lower splint 4.

[0029] In this technical solution, under the action of the spring 83 inside the main cylinder 81, the end of the secondary cylinder 82 can always fit into the upper wall of the lower clamping plate 4, thereby providing good protection for the bolt 7.

[0030] In some technical solutions, a clearance groove 9 is opened on both sides of the splint 1, and a connecting hole 10 is opened on the inner wall of the clearance groove 9. The clamp 2 is inserted into the clearance groove 9 through the connecting hole 10, and a fastening nut 11 is screwed and installed on one end of the clamp 2 located in the clearance groove 9.

[0031] In this technical solution, the cross-section of the clamp 2 is U-shaped, and the two ends of the clamp 2 are inserted into the clearance groove 9 through the connecting hole 10, and the clamp 2 is fixed by the fastening nut 11. After fixation, the inner wall of the clamp 2 will fit tightly with the external photovoltaic bracket, thereby achieving the purpose of fixing the device.

[0032] In some technical solutions, a cover shell 12 is inserted and installed in the clearance groove 9. The cover shell 12 can be connected to the outside of the fastening nut 11. The upper wall of the cover shell 12 is provided with a drainage groove 13.

[0033] In this technical solution, the cover shell 12 proposed in this article is made of rubber. The cover shell 12 can shield the fastening nut 11 to avoid contact with external rainwater. At the same time, the drainage groove 13 on the cover shell 12 can drain the rainwater falling on the cover shell 12, so that it flows down from the cover shell 12 through the drainage groove 13.

[0034] In some technical solutions, a spherical groove 14 is formed on the side wall of the lower clamping plate 4 , and a ball 15 is installed in the spherical groove 14 . The ball 15 can fit with the inner wall of the sliding groove 3 .

[0035] In this technical solution, the setting of the ball 15 can, on the one hand, reduce the friction force generated by the lower clamping plate 4 during sliding, making it slide more smoothly. At the same time, because the ball 15 supports the lower clamping plate 4, it can also prevent the lower clamping plate 4 from shaking left and right, making the device more stable when clamping the photovoltaic panel.

[0036] In some technical solutions, a water flow groove 16 is opened in the middle of the upper wall of the clamping block 1.

[0037] In this technical solution, the water flow trough 16 is provided to be able to place an external water diversion trough plate, so that it can drain the photovoltaic panels on the photovoltaic bracket through the water diversion trough plate, thereby preventing the photovoltaic panels from collapsing or shifting due to excessive water accumulation.

[0038] Working principle: When installing the photovoltaic panel on the photovoltaic bracket, first install the clamp 1 on the external photovoltaic bracket through the clamp 2, and then fix the clamp 1 by tightening the fastening nut 11 on the clamp 2. After the clamp 1 is fixed, the bolt 7 under the lower clamp 4 can be rotated so that the bolt 7 is screwed into the threaded hole 5, and the lower clamp 4 is driven to move upward continuously, so that the photovoltaic panel to be installed on the external photovoltaic bracket is spliced ​​and fixed through the cooperation of the clamp 1 and the lower clamp 4.
