Specifically, a plurality of installation frames 3 are sequentially arranged in the transverse direction between the two transverse guide rails 2, and the installation frame 3 is a rectangular frame structure with a hollow interior, and the photovoltaic panel 9 is fixedly installed inside the installation frame 3, so that the photovoltaic panel 9 is arranged using the installation frame 3.

[0032] In this embodiment, if Figure 3 , 4 As shown, the facing sides of two adjacent mounting frames 3 are hingedly connected. Specifically, a plurality of hinges 10 are arranged between the two adjacent mounting frames 3 along the longitudinal interval, and the rotation axis of the hinges 10 extends along the longitudinal direction. The two adjacent mounting frames 3 are hingedly connected by the hinges 10. In this way, the plurality of mounting frames 3 are sequentially connected by the hinges 10, and the mounting frames 3 can be folded together in the transverse direction to shrink the area, or spread out to increase the light receiving area of ​​the photovoltaic panel.

[0033] Specifically, in this embodiment, a sliding member 4 is provided on both longitudinal sides of the mounting frame 3, and the two sliding members 4 on both longitudinal sides of each mounting frame 3 are symmetrically arranged. The sliding member 4 is rotationally matched with the mounting frame 3, and the axis of relative rotation between the sliding member 4 and the mounting frame 3 extends in the longitudinal direction, and the sliding member 4 is slidably matched with the transverse guide rail 2 on the corresponding side thereof.

[0034] Such settings, such as Figure 1 , 4 As shown, the mounting frame 3 can slide laterally along the transverse guide rail 2 through the sliding member 4, the sliding member 4 rotates with the mounting frame 3, and the adjacent mounting frames 3 are hingedly connected. Then, the adjacent mounting frames 3 can be spread out on the transverse support frame 1 by sliding back to back. Then, when power generation is needed, the photovoltaic panels 9 on the mounting frames 3 can be spread out to increase the illumination area and ensure the power generation efficiency.

[0035] Adjacent mounting frames 3 can also be folded together by sliding toward each other, so that when encountering severe weather such as hail, strong wind, etc., the photovoltaic panel 9 can be folded together. On the one hand, the contact area between the photovoltaic panel 9 and the external environment is reduced, the probability of impact is reduced, and damage to the photovoltaic panel 9 is avoided. On the other hand, the folded and gathered mounting frame 3, with its side frame arranged outward, can be used to wrap the photovoltaic panel 9 with the side frame of the mounting frame 3 to isolate the photovoltaic panel 9 from the outside world, thereby reducing the contact area between the photovoltaic panel 9 and the outside world and further improving the protective effect of the photovoltaic panel 9.

[0036] At the same time, the photovoltaic bracket of the utility model only needs to be equipped with a transverse support frame 1, a transverse guide rail 2 and a mounting frame 3. The transverse support frames 1 on both sides have stable support, low safety risks, and strong impact resistance. The structure of the corresponding transverse support frame 1 can be relatively light in design.

[0038] In this embodiment, if Figure 1 , 2 As shown, one end of the transverse groove 21 is open and the other end is closed (not shown in the figure). On the one hand, the open end is used to facilitate the installation of the sliding member 4 into the transverse groove 21, thereby completing the installation of the mounting frame 3.

[0042] With such an arrangement, the sliding seat 41 can be used to support the traveling wheel 43 in the vertical direction, thereby preventing the rotating shaft 5 of the traveling wheel 43 from being damaged by force and increasing the service life. The two traveling wheels 43 facing each other in the longitudinal direction are respectively abutted in the corresponding transverse grooves 21, thereby preventing the installation frame 3 from moving in the longitudinal direction, increasing stability and facilitating the sliding of the sliding seat 41.
