[0031] In order to make the technical means, creative features, achieved purposes and effects achieved by the present invention easy to understand, the present invention will be further described.

[0032] Refer to Figure 1 , a photovoltaic cell installation and fixing device, comprising a fixing mechanism 1 and a moving mechanism 2, and moving mechanisms 2 are symmetrically arranged on the left and right at the top of the two fixing mechanisms 1;

[0033] Refer to Figure 1 , Figure 2 and Figure 4 , the fixing mechanism 1 includes a fixed support 11, a limiting plate 12, a U-shaped frame 13, a horizontal plate 14, a threaded rod 15, a support rod 16, a fixed truss 17, a fixing component 18 and a clamping component 19. The fixed support 11 has a U-shaped structure with an opening downward. At the front and rear of the bottom of the two vertical segments of the fixed support 11, limiting plates 12 are symmetrically and fixedly installed. Conical screws for fixing are provided on the limiting plates 12. At the bottom of the fixed support 11, a U-shaped frame 13 with an opening downward is fixedly installed. Sliding grooves are symmetrically opened on the two vertical segments of the inner frame surface of the U-shaped frame 13. A horizontal plate 14 is slidably arranged in the two sliding grooves together. A threaded rod 15 is rotatably arranged between the U-shaped frame 13 and the fixed support 11. The threaded rod 15 is threadedly connected to the horizontal plate 14 and fixedly installed with a circular handle after passing through the top of the U-shaped frame 13. A support rod 16 is fixedly installed on the top of the horizontal plate 14. The top of the support rod 16 slides through the top of the U-shaped frame 13 and extends upward. A fixed truss 17 is jointly arranged at the tops of the left and right support rods 16. The support rod 16 and the fixed truss 17 are hinged by a pin shaft. Fixing components 18 are arranged at the left and right ends of the fixed truss 17. A clamping groove is opened at the center position of the top of the fixed truss 17. A clamping component 19 is arranged in the clamping groove; a detachable universal wheel 111 is arranged on the inner end surface of the fixed support 11.

[0034] In the original state, first, install the universal wheel 111 on the fixed support 11. The detachable universal wheel 111 facilitates the movement of the fixing mechanism 1, avoiding the problem of increased labor caused by the traditional method of requiring multiple people to lift and install. After installing the universal wheel 111, move the fixing mechanism 1 with the moving mechanism 2 installed to the open space where power supply is needed. After moving, the fixed support 11 can be fixedly installed on the open space where power supply is needed through the set tapered screw. The fixed support 11 is of a U-shaped structure, which not only facilitates the installation of the fixing mechanism 1 on the open space but also on the color steel plate of the electric vehicle charging shed where power supply is needed, thus increasing the applicable range of the device. After the fixing mechanism 1 is fixedly installed, quickly install the moving mechanism 2 on the fixing mechanism 1. Since the fixing mechanism 1 and the moving mechanism 2 are detachably arranged, it is convenient for the transportation of the installation components. After installing the moving mechanism 2 on the fixing mechanism 1, finally install the photovoltaic cell that needs power supply on the moving mechanism 2. When adjusting the tilt angle of the photovoltaic cell according to the different illumination times in summer and winter, the specific adjustment method is as follows: Rotate the circular handle on one side of the U-shaped frame 13, so that the circular handle drives the threaded rod 15 to rotate. At this time, under the limitation of the sliding groove, the horizontal plate 14 drives the support rod 16 to move upward or downward, so that the support rod 16 drives the fixed truss 17 to tilt at a certain angle, and the fixed truss 17 makes the moving mechanism 2 drive the photovoltaic cell to tilt at a certain angle, thereby enhancing the illumination effect on the photovoltaic cell.

[0035] Refer to Figure 4 , the fixing component 18 includes a clamping rod 181, a moving plate 182 and a return spring 183. Corresponding fixing grooves to the clamping blocks 22 are symmetrically opened at the left and right ends of the top of the fixed truss 17. Moving grooves connected to the fixing grooves are symmetrically opened at the left and right ends of the fixed truss 17. The clamping rod 181 is slidably arranged in the moving groove. A moving plate 182 is fixedly installed at one end of the clamping rod 181 away from the fixed truss 17. The moving plate 182 and the fixed truss 17 are fixedly connected through the return spring 183.

[0036] Refer to Figure 1 , Figure 4 and Figure 6The movable mechanism 2 includes a mounting plate 21, a clamping block 22, a supporting truss 23, a clamping plate 24 and a limit assembly 25. The top of the two fixing mechanisms 1 is symmetrically provided with mounting plates 21 on the left and right sides. The mounting plate 21 is an L-shaped structure. The bottom of the horizontal section of the mounting plate 21 is evenly fixed with a clamping block 22 from front to back. A circular through hole is provided on the clamping block 22. The vertical sections of the left and right mounting plates 21 are opposite to each other in an eight-shaped structure with the large-diameter section facing upward and are fixed with anti-slip pads. The top center position of the two fixing mechanisms 1 is jointly provided with a supporting truss 23. The top of the supporting truss 23 is flush with the top of the horizontal section of the mounting plate 21. The bottom of the supporting truss 23 is evenly fixed with a clamping plate 24 corresponding to the clamping groove from front to back. The left and right side walls of the clamping plate 24 are evenly provided with arc grooves from top to bottom, and the top of the supporting truss 23 is evenly provided with a limit assembly 25 from front to back.

[0037] After the fixing mechanism 1 is installed and fixed, the mounting plate 21 is mounted on the plurality of fixed trusses 17 (eg Figure 1 As shown), the clamping block 22 at the bottom of the mounting plate 21 is clamped into the left-right symmetrical fixing groove at the top of the fixed truss 17. At this time, under the action of the return spring 183, the clamping rod 181 passes through the circular through hole on the clamping block 22 to limit and fix the mounting plate 21, thereby facilitating the rapid installation and removal of the mounting plate 21. After the mounting plate 21 is installed and fixed, the clamping plate 24 on the support truss 23 is quickly installed and fixed through the clamping assembly 19. By setting the top of the support truss 23 and the top of the horizontal section of the mounting plate 21 to be flush, the stability of the photovoltaic cell support can be enhanced. Finally, the photovoltaic cell is installed between the left and right mounting plates 21. The vertical sections of the two mounting plates 21 are arranged in an eight-shaped structure with the large-diameter section facing upward, which can leave a certain amount of space margin for the rapid installation of the photovoltaic cell. Finally, the limiting assembly 25 can be used to limit and fix the installed photovoltaic cell to prevent it from falling, avoiding the problem of increasing labor and reducing work efficiency caused by traditional screw fixing.

[0038] See Figure 4 and Figure 6 The clamping assembly 19 includes an extrusion spring 191, a rectangular block 192 and a spherical clamping bead 193. The clamping groove is symmetrically provided with rectangular grooves evenly distributed from top to bottom on both sides. A rectangular block 192 is slidingly provided in the rectangular groove through the extrusion spring 191. A hemispherical groove is provided at one end of the rectangular block 192 away from the extrusion spring 191. A spherical clamping bead 193 is rollingly provided in the hemispherical groove. The spherical clamping bead 193 corresponds to the arc groove.

[0039] After the mounting plate 21 is installed and fixed, the supporting truss 23 is mounted on multiple fixed trusses 17, and the clamping plate 24 at the bottom of the supporting truss 23 is installed in the clamping groove. At this time, under the action of the extrusion spring 191, the rectangular block 192 drives the spherical clamping bead 193 to clamp into the arc groove on the side wall of the clamping plate 24, thereby limiting and fixing the supporting truss 23.

[0040] See Figure 4 and Figure 5 The limiting assembly 25 includes an isolation baffle 251, a rotating rod 252, a spring rod 253 and a pressing plate 254. The isolation baffle 251 is evenly fixedly installed on the top of the support truss 23 from front to back. A circular groove is provided on the top of the isolation baffle 251, and a rotating rod 252 is rotatably arranged in the circular groove. A mounting groove is provided on the top of the rotating rod 252, and a spring rod 253 is fixedly installed in the mounting groove. A pressing plate 254 is fixedly installed on the top of the spring rod 253; a rubber layer is fixedly installed on the bottom of the pressing plate 254 and on both sides of the rotating rod 252.

[0041] In the original state, the pressing plate 254 and the supporting truss 23 are in a parallel state. When installing the photovoltaic cell, one end of the photovoltaic cell is in contact with the isolation baffle 251. After the photovoltaic cell is installed on the mounting plate 21, the pressing plate 254 is pulled upward and the rotating rod 252 is rotated at the same time. The rotating rod 252 causes the spring rod 253 to drive the pressing plate 254 to rotate, so that the pressing plate 254 and the supporting truss 23 are in a cross-shaped structure. After the rotation is completed, the pressing plate 254 is released. At this time, under the action of the spring rod 253, the pressing plate 254 limits and fixes the two adjacent photovoltaic cells to prevent the photovoltaic cells from falling.

[0042] See Figure 7 The bottom of the rear end of the horizontal section of the mounting plate 21 is provided with a connecting groove, and the bottom of the front end of the horizontal section of the mounting plate 21 is fixedly installed with an extension plate 211, and the front end surface of the extension plate 211 is fixedly installed with a rectangular plate 212. The bottom of the rectangular plate 212 is provided with a square groove, and the front and rear sides of the rectangular plate 212 are provided with rectangular through grooves connected to the square groove. A limit block 213 is slidingly arranged in the rectangular through groove. The limit block 213 is an inclined structure from top to bottom. An extrusion plate 214 is fixedly installed at one end of the limit block 213 located in the square groove, and the extrusion plate 214 and the inner wall of the square groove are fixedly connected by a plurality of movable springs 215.

[0043] When a row of photovoltaic cells is not enough, the mounting plates 21 and 21 can be docked so that the protruding plate 211 on the rear mounting plate 21 is located on the lower side, and the connecting groove on the front mounting plate 21 is clamped to the top of the rectangular plate 212. At this time, under the action of the movable spring 215, the extrusion plate 214 is clamped into the connecting groove, so that the mounting plates 21 and 21 can be quickly docked, thereby increasing the stability of the connection between the mounting plates 21 and 21. When disassembly is required, press the two extrusion plates 214 to move toward each other.

[0044] Specific work: Step 1, in the original state, first install the universal wheel 111 on the fixed support 11. After the universal wheel 111 is installed, move the fixed mechanism 1 on which the moving mechanism 2 is installed to the open space that needs power supply. After moving, the fixed support 11 can be fixedly installed to the open space that needs power supply through the set conical screws.

[0045] Step 2: After the fixing mechanism 1 is installed and fixed, the mounting plate 21 is mounted on the plurality of fixed trusses 17 (eg Figure 1 As shown), the clamping block 22 at the bottom of the mounting plate 21 is clamped into the left-right symmetrical fixing groove at the top of the fixed truss 17. At this time, under the action of the return spring 183, the clamping rod 181 passes through the circular through hole on the clamping block 22 to limit and fix the mounting plate 21. After the mounting plate 21 is installed and fixed, the supporting truss 23 is erected on multiple fixed trusses 17, and the clamping plate 24 at the bottom of the supporting truss 23 is installed in the clamping groove. At this time, under the action of the extrusion spring 191, the rectangular block 192 drives the spherical clamping bead 193 to clamp into the arc groove on the side wall of the clamping plate 24, thereby limiting and fixing the supporting truss 23.

[0046] The third step is to install the photovoltaic cell on the mounting plate 21 so that one end of the photovoltaic cell contacts the isolation baffle 251. After the photovoltaic cell is installed on the mounting plate 21, pull the pressing plate 254 to move upward and rotate the rotating rod 252 at the same time. The rotating rod 252 causes the spring rod 253 to drive the pressing plate 254 to rotate so that the pressing plate 254 and the supporting truss 23 are in a cross-shaped structure. After the rotation is completed, release the pressing plate 254. At this time, under the action of the spring rod 253, the pressing plate 254 limits and fixes the two adjacent photovoltaic cells.

[0047] Step 4. When a row of photovoltaic cells is not enough, the mounting plates 21 and 21 can be docked so that the protruding plate 211 on the rear mounting plate 21 is located at the bottom, and the connecting groove on the front mounting plate 21 is clamped to the top of the rectangular plate 212. At this time, under the action of the movable spring 215, the extrusion plate 214 is clamped into the connecting groove, so that the mounting plates 21 and 21 can be quickly docked. When disassembly is required, press the two extrusion plates 214 to move toward each other.
