[0049] Specifically, at least two adjustment holes 31 are spaced apart on the mounting plate in the second direction, and a bolt is inserted in each adjustment hole 31. The adjustment hole 31 is a waist-shaped hole, which is extended in the second direction. The position of the mounting plate can be adjusted by adjusting the position of the bolt in the adjustment hole 31. This arrangement can adapt the position of the mounting plate according to photovoltaic components 6 of different sizes, so that the first snow cutting piece 1 and the second snow cutting piece 2 are in a position where they can cut snow, so as to ensure the snow separation device 100 has the effect of blocking and cutting the accumulated snow.

[0050] In one embodiment, a mounting groove 32 is provided at one end of the mounting member 3 , a side wall of the water tank 7 is inserted into the mounting groove 32 , and the other end of the mounting member 3 is connected to the first snow cutting member 1 .

[0055] Specifically, after the first snow cutter 1 and the second snow cutter 2 are connected together, they are in an L-shaped rectangular tube shape. The rectangular tube is larger in size and has higher strength. Such a configuration can improve the structural strength of the snow separation device 100 to ensure the effect of blocking and separating snow accumulation, and is not prone to deformation after long-term use. In some other embodiments, the first snow cutter and the second snow cutter can also be other profile structures.

[0056] In one embodiment, one or more second snow cutters 2 are connected to the first snow cutter 1. When multiple second snow cutters 2 are connected to the first snow cutter 1, the multiple second snow cutters 2 are spaced apart and distributed along the first direction.

In this way, the blocking and cutting effects of the snow separating device 100 on the snow are increased by increasing the number of the second snow cutters 2.

[0058] In one embodiment, a plurality of snow distributing devices 100 are distributed on the lower side portion 61 , and the plurality of snow distributing devices 100 are distributed at intervals along the first direction.

[0059] Specifically, there may be multiple photovoltaic components 6 . When the number of photovoltaic components 6 increases, it is necessary to provide multiple snow separation devices 100 on the lower side 61 of the photovoltaic component module to further enhance the snow blocking and snow cutting effects on the lower side 61 .

[0060] In one embodiment, the snow separation device 100 includes a rolling member 4, which is rotatably mounted on a second snow cutting member 2, wherein the axis of the rolling member 4 is parallel to the first direction, the rolling member 4 is arranged close to the photovoltaic component module, and a snow cutting protrusion 41 is provided on the outer surface of the rolling member 4, and the snow cutting protrusion 41 is used to cut the accumulated snow.

When in the blocking state, the swing member 51 is arranged parallel to the first direction, that is, the snow is blocked and cut at the lower side 61. When there is a lot of snow that cannot fall in the gap between the swing member 51 and the photovoltaic module 6, the swing member 51 can be rotated to switch to the swinging state. The swing member 51 rotates relative to the fixed member 52, and the snow on the photovoltaic module 6 can be pushed out. In this way, the snow on the photovoltaic module 6 can be actively cut, thereby improving the snow cutting effect.

[0064] In one embodiment, the snow separation device 100 includes a torsion spring, and a torsion spring is provided at the rotating part of the swing member 51. One end of the torsion spring abuts against the swing member 51, and the other end abuts against the fixed member 52. When the swing member 51 completes snow sweeping, the torsion spring is used to reset the swing member 51.

[0065] Specifically, a torsion spring is provided at the rotating part of the swing member 51. The torsion spring is in a relaxed state when the swing member 51 is in a blocking state. When the swing member 51 changes to a swinging state, the torsion spring gradually contracts. When the swing member 51 completes the movement of the snow, the contraction degree of the torsion spring is the largest. At this time, the swing member 51 can be rotated back to the blocking state by the elastic force of the torsion spring. This arrangement can avoid the situation where the swing member 51 is not reset, resulting in a reduced blocking effect on the snow. In some other embodiments, a compression spring is provided on the fixed member, and the compression spring is connected to the swing member. When the swing member is in a blocking state, the spring is in a relaxed state. After the swing member swings, the spring is gradually contracted. After the contraction is completed, the swing member is reset by its own elastic force.

[0066] In one embodiment, the snow separation device 100 includes a pulling member 53 and a roller 54. The roller 54 is movably installed on the end of the fixed member 52. The pulling member 53 is sleeved on the roller 54 and connected to the swinging member 51. The pulling member 53 is movably inserted into the fixed member 52. The swinging member 51 is driven to swing by pulling the pulling member 53.

[0067] Specifically, the pulling member 53 is a pull rope, one end of which is connected to the swing member 51, and the other end of which is wound around the roller 54 and placed close to the fixing member 52, and falls from above the second snow-cutting member 2, and a pull ring is also provided on this end. The user pulls the pull rope to drive the swing member 51 to swing and remove snow, and the swing member 51 is reset by the torsion spring. This arrangement makes it more convenient for the user to operate the swing member 51. In some other embodiments, a motor can be added to control the pulling of the pull rope, thereby controlling the swing member to swing.
