It is a new power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. Photovoltaic panels are also called solar power generation panels. In the existing technology, photovoltaic panels need to use clamps and bolts when assembling, which is inconvenient.

[0003] An existing patent discloses a photovoltaic panel installation and fixing device, with patent authorization number CN 213319776 U. The photovoltaic panel is placed on a fixed plate and a sliding plate, and the screw is rotated to drive the sliding plate to slide, so that the U-shaped clamp is clamped on the side of the photovoltaic panel. Then the fixing bolt is rotated to insert the head of the fixing bolt into the fixing socket, so that the gasket and the surface of the photovoltaic panel are in close contact, which is convenient for operation.

[0004] However, in patent authorization number CN 213319776 U, the photovoltaic panel is placed on a fixed plate and a sliding plate, and the screw is rotated to drive the sliding plate to slide, so that the U-shaped clamp is clamped on the side of the photovoltaic panel, and then the fixing bolt is rotated to insert the head of the fixing bolt into the fixing hole so that the gasket and the surface of the photovoltaic panel are in close contact. Since the fixing hole is opened at the photovoltaic panel, it is easy to damage the photovoltaic panel in the process of opening the fixing hole. In order to be able to fix the installation without damaging the photovoltaic panel, we have proposed a photovoltaic panel installation and fixing device to solve the above-mentioned problems.

[0031] Please refer to Figure 1-6 , an installation and fixing device for a photovoltaic panel, comprising an outer frame 2 for covering the edge of the photovoltaic panel body 1, and further comprising a metal groove 3;

[0032] A double-headed screw 4 with opposite threads is rotatably connected to the inner side of the metal groove 3. A cross groove 5 is opened at the bottom end of the double-headed screw 4 with opposite threads, and guide holes 6 are opened on both outer walls of the metal groove 3.

[0033] Clamping sleeves 7 are clamped at the top and bottom of the outer frame 2. A connecting arm 8 is welded to the surface of the clamping sleeve 7 close to the metal groove 3. A connecting seat 9 that is screwed to the double-headed screw 4 with opposite threads is integrally formed at one end of the connecting arm 8 away from the clamping sleeve 7. Guide posts 10 that are slidably connected to the guide holes 6 are welded to both outer walls of the connecting seat 9.

[0034] It should be noted that when the installation and fixing device for the photovoltaic panel is in use, two photovoltaic panel bodies 1 are spliced together and placed between two card sleeves 7. By using a flat-head screwdriver to abut against the cross-shaped groove 5 and driving the double-headed screw 4 clockwise to cooperate with the metal groove 3 to rotate, the guide posts 10 welded to the side wall of the connecting seat 9 cooperate with the guide holes 6 to slide, and then the connecting arm 8 is used to make the two card sleeves 7 move towards each other, so that the card sleeves 7 clamp the splicing part of the two photovoltaic panel bodies 1. It can not only install and fix photovoltaic panel bodies 1 of different sizes, but also will not damage the photovoltaic panel bodies 1 during the fixed installation process.

[0035] As Figure 1 , Figure 4 shown, an anti-slip rubber pad 11 is compound-bonded to the inner wall of the card sleeve 7, and the anti-slip rubber pad 11 abuts against the outer wall of the outer frame 2;

[0036] It should be noted that by the anti-slip rubber pad 11 provided on the inner wall of the card sleeve 7 abutting against the outer frame 2, it can not only increase the friction between the card sleeve 7 and the photovoltaic panel body 1, ensure the stability of the installation, but also play a protective role for the photovoltaic panel body 1.

[0037] As Figure 3 , Figure 4 , Figure 5 shown, the outer diameter of the guide post 10 is adapted to the width of the guide hole 6;

[0038] It should be noted that through the clearance fit between the guide post 10 and the guide hole 6, the stability of the connecting seat 9 during movement can be ensured.

[0039] As Figure 5 , Figure 6 shown, bearings 12 and damping rubber sleeves 13 are respectively installed at both ends of the metal groove 3. Both ends of the double-headed screw 4 are provided with smooth surface structures, and both ends of the double-headed screw 4 are in interference connection with the bearings 12 and the damping rubber sleeves 13 respectively;

[0040] It should be noted that by setting the bearing 12, the double-headed screw 4 can rotate self-rotationally in cooperation with the metal groove 3, and the friction force with the double-headed screw 4 is increased through the damping rubber sleeve 13, which can effectively prevent the double-headed screw 4 from rotating, and then ensure the clamping force of the card sleeve 7 on the photovoltaic panel body 1.

[0041] As Figure 1 shown, a strip-shaped hole 14 is opened on the surface of the card sleeve 7 away from the bayonet, and the strip-shaped hole 14 corresponds to the splicing joint of the photovoltaic panel body 1, and a through hole is opened at the position of the anti-slip rubber pad 11 corresponding to the strip-shaped hole 14;

[0042] It should be noted that when the ferrule 7 clamps the photovoltaic panel body 1, it corresponds to the joint where the two photovoltaic panel bodies 1 are spliced through the strip-shaped hole 14, so as to be able to adjust the ferrule 7 to clamp the splicing part of the two photovoltaic panel bodies 1 and ensure the equality of the clamping force.

[0043] When in use: Splice the two photovoltaic panel bodies 1 together and place them between the two ferrules 7. By using a flat-tip screwdriver to abut against the cross-shaped groove 5 and drive the positive and negative double-headed screw 4 to rotate clockwise in cooperation with the metal groove 3, the guide post 10 welded to the side wall of the connecting seat 9 is made to slide in cooperation with the guide hole 6, and then the two ferrules 7 are made to move towards each other through the connecting arm 8, so that the ferrules 7 are engaged with the splicing part of the two photovoltaic panel bodies 1.

[0044] Finally, it should be noted that: The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
