DETAILED DESCRIPTION

[0021] For the convenience of understanding of those skilled in the art, the utility model is described in further detail below in combination with the drawings and specific embodiments.

[0022] As shown in Figure 1 , 2 , a photovoltaic support truss comprises a truss frame body 100, which is an important foundation for supporting photovoltaic panels. The top of the frame body 100 is provided with a crossbeam 110, the two ends of the crossbeam 110 are each provided with a side pressing assembly 200, and a middle pressing assembly 300 is arranged between the two end side pressing assemblies 200. The side pressing assembly 200 is used for fixing the photovoltaic panels installed at the edges of a photovoltaic panel group, and the side pressing assembly 200 comprises a first connecting block 210, a first backing plate 220 is arranged above the first connecting block 210, and in the installation process of the photovoltaic panels, the first backing plate 220 is placed on the bottom surface of the frame of the photovoltaic panels.

[0023] As shown in Figure 2 , 3 , the other end of the first connecting section 231 is further provided with a lower pressing section 233, and one side of the first backing plate 220 is provided with a resisting protrusion 221 for resisting the lower pressing section 233. A bolt is arranged to pass through the first connecting section 231 and the first backing plate 220 and is connected with the first connecting block 210, and the side pressing piece 230 is pressed downward by screwing the bolt. When the side pressing piece 230 is pressed downward, the end of the lower pressing section 233 is pressed against the first backing plate 220, which can prevent the side pressing piece 230 from being pressed too much and at the same time provide a fulcrum for the pressing section. Compared with the traditional side pressing block, the lower pressing of the utility model is pressed against the upper side of the first backing plate 220 and does not directly contact the crossbeam 110, which can prevent the crossbeam 110 from being abraded.

[0024] As shown in Figure 4 , 5As shown, the medium-voltage assembly 300 is used to fix two adjacent photovoltaic panels in a photovoltaic panel array. The medium-voltage assembly 300 includes a second connecting block 310, and a second pad 310 is provided above the second connecting block 310. The second pad 310 is placed on the bottom of the frame of the two adjacent photovoltaic panels. A medium-voltage component 330 is provided above the second pad 310. The medium-voltage component 330 includes a second connecting section 331. Both ends of the second connecting section 331 are provided with second pressing sections 332. Bolts pass through the medium-voltage component 330 and the second pad 310 and connect to the second connecting block 310. By tightening the bolts, the medium-voltage component 330 is pressed down, thereby fixing the photovoltaic panels.

[0025] Compared with traditional edge pressure blocks and middle pressure blocks, the edge pressure member 230 and the middle pressure member 330 in this embodiment have a larger pressure contact area, which provides a better fixing effect for photovoltaic panels.

[0026] like Figure 2 , 4 As shown, the crossbeam 110 is provided with an upper guide rail 111 and a lower guide rail 112. The first connecting block 210 and the second connecting block 310 are installed in the upper guide rail 111. Therefore, by tightening the bolts on the edge pressing assembly 200 and the medium-pressure assembly 300, the photovoltaic panel can be pressed onto the crossbeam 110. Loosening the bolts on the edge pressing assembly 200 and the medium-pressure assembly 300 allows them to slide on the guide rail, facilitating position adjustment. The edge pressing assembly 200 also includes a first stabilizing member 240, which is framed on the edge pressing member 230 and the crossbeam 110. The medium-pressure assembly 300 also includes a second stabilizing member 340, which is framed on the medium-pressure member 330 and the crossbeam 110. Both the first stabilizing member 240 and the second stabilizing member 340 are U-shaped structures. The first stabilizing member 240 is provided with a first hooking protrusion 241, and the second stabilizing member 340 is provided with a second hooking protrusion 341. Both the first hooking protrusion 241 and the second hooking protrusion 341 are hooked into the lower guide rail 112.

[0027] like Figure 2As shown, the upper frame plate of the first stabilizer 240 covers the upper side of the first connecting segment 231, and the lower frame plate of the first stabilizer 240 is hooked to the lower rail 112 of the cross beam 110, so that the first stabilizer 240 can limit the movement of the side pressing member 230 in multiple directions and enhance the stability of the side pressing member 230 under force in multiple directions. The upper frame plate of the second stabilizer 340 covers the upper side of the second connecting segment 331, and the lower frame plate of the second stabilizer 340 is hooked to the lower rail 112 of the cross beam 110, so that the second stabilizer 340 can limit the movement of the middle pressing member 330 in multiple directions and enhance the stability of the middle pressing member 330 under force in multiple directions. After the middle pressing member 330 and the side pressing member 230 are removed, the first stabilizer 240 and the second stabilizer 340 can move up and down, which is convenient for mounting and dismounting on the cross beam 110.

[0028] As shown in Figure 2 , 3 , 4, 5, the pressing surfaces of the first lower pressing segment 232 and the second lower pressing segment 332 and the pad surfaces of the first pad plate 220 and the second pad plate 310 are provided with shock-absorbing pads 223 made of rubber material, which can provide certain shock-absorbing effect for the photovoltaic panel after installation and increase the friction of the side pressing assembly 200 and the middle pressing assembly 300 on the photovoltaic panel. The pressing surfaces of the first lower pressing segment 232 and the second lower pressing segment 332 and the pad surfaces of the first pad plate 220 and the second pad plate 310 are provided with limiting protrusions 222 for limiting the positions of the shock-absorbing pads 223, which can prevent the shock-absorbing pads 223 from displacement.

[0029] The above embodiments are the preferred implementation of the present application, and are not a limitation of the present application. Any obvious replacement without departing from the inventive concept of the present application is within the protection scope of the present application.
