[0024] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0025] like Figure 1-5 A solar panel deicing device shown in the figure includes a photovoltaic panel 1 in an inclined state, a bracket 10, a snow removal component 2 and a deicing component 3, the photovoltaic panel 1 is tilted and fixed on the bracket 10 and the photovoltaic panel 1 is provided with a snow removal component 2, the snow shoveling belt 22 of the snow removal component 2 is attached to the surface of the photovoltaic panel 1 and moves along the photovoltaic panel 1, the water-absorbing sponge 32 of the deicing component 3 that is full of liquid deicing agent is arranged on the snow shoveling belt 22 and the liquid deicing agent is squeezed out by using a pressure plate 33 above the snow shoveling belt 22, and the squeezed liquid deicing agent flows with the surface of the photovoltaic panel 1 and is collected by the storage box 30 under the bracket 10.

[0026] The snow removal assembly 2 includes a fixed bracket 21, an active rod 23, a driven rod 24, a chain transmission member 4 and a through hole 25. The outer side of the photovoltaic panel 1 is fixedly connected to the limit frame 20, and the fixed bracket 21 is symmetrically fixedly connected to the upper and lower sides of the limit frame 20. The active rod 23 and the driven rod 24 are rotatably connected to the fixed brackets 21 on the upper and lower sides of the limit frame 20, and the chain transmission member 4 is connected between the active rod 23 and the driven rod 24. A snow shoveling belt 22 is also connected between the active rod 23 and the driven rod 24, and the through hole 25 is opened on one side of the snow shoveling belt 22. The through hole 25 has the same size as the light irradiation surface of the photovoltaic panel 1, and a plurality of water flow holes 26 are opened on the other side of the snow shoveling belt 22.

[0027] The snow shoveling belt 22 of the snow removal assembly 2 is annular in structure, and the through hole 25 of the snow shoveling belt 22 is opposite to the light irradiation surface of the photovoltaic panel 1, so that the normal illumination of the photovoltaic panel 1 will not be affected. If there is snow accumulated on the surface of the photovoltaic panel 1, the active rod 23 and the driven rod 24 are driven to rotate through the chain transmission member 4, and then the snow shoveling belt 22 moves around the active rod 23 and the driven rod 24. The snow shoveling belt 22 is closely attached to the surface of the photovoltaic panel 1, and then the snow shoveling belt 22 can be used to push the accumulated snow to slide downward. Since the photovoltaic panel 1 is in an inclined state, the accumulated snow can be transported to the bottom of the lower side of the photovoltaic panel 1. Since the snow shoveling belt 22 is attached to the photovoltaic panel 1, the snow shoveling belt 22 can also remove the floating snow on the surface of the photovoltaic panel 1 while moving, thereby achieving the purpose of fully removing snow.

[0028] The de-icing assembly 3 includes a fixing plate 31, a plurality of fixing plates 31 are fixedly connected to the other side of the snow shoveling belt 22, and a water-absorbing sponge 32 is provided on one side of the surface of the fixing plate 31, the water flow hole 26 is provided between two adjacent fixing plates 31, the bottom of the bracket 10 is fixedly connected to the storage box 30, and the storage box 30 stores liquid de-icing agent inside, the snow shoveling belt 22 drives the fixing plate 31 to move and immerses the water-absorbing sponge 32 into the liquid de-icing agent, and the limit A limiting bracket 34 is provided above the frame 20 and the middle part of the limiting bracket 34 is rotatably connected to the pressure plate 33, the pressure plate 33 is opposite to the water-absorbing sponge 32 and the pressure plate 33 is used to pressurize the water-absorbing sponge 32 so that the liquid de-icing agent in the water-absorbing sponge 32 is squeezed out, and the squeezed liquid de-icing agent contacts the surface of the photovoltaic panel 1 through the water flow hole 26, and the lower side of the snow shovel belt 22 is attached to the storage box 30 so that the liquid de-icing agent can be collected again in the storage box 30.

[0029] In order to prevent the surface of the photovoltaic panel 1 from freezing, a storage box 30 is provided at the bottom of the bracket 10. The storage box 30 is provided with liquid de-icing agent inside. Therefore, as the snow shoveling belt 22 moves, the fixing plate 31 and the absorbent sponge 32 can be synchronously driven to move, so that the fixing plate 31 can intermittently enter the storage box 30, and the absorbent sponge 32 can be rinsed and absorbed by the liquid de-icing agent after being squeezed, or it can be intermittently pressed against the pressing plate 33, and the liquid de-icing agent inside the absorbent sponge 32 is squeezed out by the pressing plate 33. The squeezed liquid de-icing agent flows downward along the photovoltaic panel 1 and the snow shoveling belt 22, and then contacts the photovoltaic panel 1 through the water flow hole 26, so that the surface of the photovoltaic panel 1 can contact the liquid de-icing agent. In this way, the use of liquid de-icing agent can prevent the surface of the photovoltaic panel 1 from freezing, and even if floating ice is generated, it will be shoveled off by the snow shoveling belt 22, and the outflowing liquid de-icing agent will also flow back into the storage box 30 for repeated use.

[0030] A rotating shaft 35 is fixedly connected through the middle of the pressure plate 33 and the rotating shaft 35 is rotatably connected to the limiting bracket 34. The end of the rotating shaft 35 passes through the limiting bracket 34 and a return spring is fixedly connected between the rotating shaft 35 and the limiting bracket 34. A magnet 36 is embedded on the side of the limiting bracket 34 facing the pressure plate 33, and the pressure plate 33 is attracted to the magnet 36.

[0031] The existence of the pressure plate 33 can squeeze the water-absorbing sponge 32. When the snow shoveling belt 22 drives the fixed plate 31 to move in the direction of the pressure plate 33, as the snow shoveling belt 22 moves, the fixed plate 31 continuously squeezes the pressure plate 33. In the initial state, under the action of the return spring and the magnet 36, the pressure plate 33 can maintain a stable state. As the fixed plate 31 squeezes it, the pressure plate 33 is gradually pushed away from the magnet so that the fixed plate 31 can pass through the pressure plate 33. After passing through the pressure plate 33, driven by the magnet 36 and the return spring, the pressure plate 33 returns to its initial state, so that the next water-absorbing sponge 32 can be squeezed again.

[0032] A cover plate 37 is provided on the top of the storage box 30. The cover plate 37 is in an inclined structure and the high side of the cover plate 37 is flush with the low side of the snow shoveling belt 22. A liquid inlet is left between the high side of the cover plate 37 and the snow shoveling belt 22. A water-absorbing sponge 38 is provided inside the storage box 30. The fixed plate 31 moves into the interior of the storage box 30 and the fixed plate 31 squeezes the water-absorbing sponge 38.

[0033] The cover plate 37 and the water-absorbing sponge 238 are provided to prevent excessive snow from entering the storage box 30. The snow-shoveling belt 22 drives the snow to move downward. Since one side of the storage box 30 is located at the lower side of the snow-shoveling belt 22, some snow will inevitably remain at the liquid inlet. The fluffy nature of the water-absorbing sponge 238 can absorb the snow and prevent excessive snow from entering the storage box 30. After the snow on the surface of the photovoltaic panel 1 is cleared, the snow-shoveling belt 22 can move in the opposite direction. First, the fixed plate 31 is used to move the snow at the liquid inlet. The accumulated snow is picked up and kept away from the storage box, so that the accumulated snow can also be removed. Then the snow shoveling belt 22 moves in the forward direction, and the water-absorbing sponge 32 is used to make the liquid de-icing agent flow on the photovoltaic panel 1. The flowing liquid de-icing agent can enter the storage box 30 again through the liquid inlet, so as to realize the recycling of the liquid de-icing agent. The cleaning liquid can also be stored inside the storage box 30. When there is a lot of dust on the surface of the photovoltaic panel 1, the surface of the photovoltaic panel 1 can also be dedused by using the flowing cleaning liquid and the snow shoveling belt 22.

[0034] The chain transmission member 4 includes a chain 40 and a driving motor 41. A driving sprocket 42 and a driven sprocket 43 are coaxially fixedly sleeved at both ends of the active rod 23 and the driven rod 24. The chain 40 is connected between the active sprocket 42 and the driven sprocket 43. A driving motor 41 is provided at the bottom of the bracket 10, and the output shaft of the driving motor 41 is connected to the active rod 23 by means of a belt transmission member 44. A fixing seat 45 is provided at the bottom of the driving motor 41.

[0035] The driving motor 41 can use the belt transmission part 44 to rotate the active rod 23, and the chain 40 set between the active rod 23 and the driven rod 24 can drive the driven rod 24 to rotate, thereby realizing the movement of the snow shovel belt 22 and achieving the function of snow and ice removal.

[0036] Working principle: the snow shoveling belt 22 of the snow removal component 2 is annular in structure, and the through hole 25 of the snow shoveling belt 22 is opposite to the light irradiation surface of the photovoltaic panel 1, so that the normal illumination of the photovoltaic panel 1 will not be affected. If there is snow on the surface of the photovoltaic panel 1, the active rod 23 and the driven rod 24 are driven to rotate through the chain transmission member 4, and then the snow shoveling belt 22 moves around the active rod 23 and the driven rod 24, and the snow shoveling belt 22 is close to the surface of the photovoltaic panel 1, and then the snow shoveling belt 22 can be used to push the accumulated snow to slide downward. Since the photovoltaic panel 1 is in an inclined state, the accumulated snow can be transported to the bottom of the lower side of the photovoltaic panel 1. Since the snow shoveling belt 22 is close to the photovoltaic panel 1, the snow shoveling belt 22 can also remove the floating snow on the surface of the photovoltaic panel 1 while moving, so as to achieve the purpose of fully removing snow. In order to prevent the surface of the photovoltaic panel 1 from freezing, a storage is provided at the bottom of the bracket 10. The box 30 has a liquid de-icing agent inside, so as the snow shoveling belt 22 moves, the fixed plate 31 and the absorbent sponge 32 can be moved synchronously, so that the fixed plate 31 can intermittently enter the storage box 30, and the absorbent sponge 32 can be rinsed and absorbed by the liquid de-icing agent after being squeezed, and can also be intermittently pressed against the pressing plate 33, and the liquid de-icing agent inside the absorbent sponge 32 can be squeezed out by the pressing plate 33. The squeezed liquid de-icing agent flows downward along the photovoltaic panel 1 and the snow shoveling belt 22, and then contacts the photovoltaic panel 1 through the water flow hole 26, so that the surface of the photovoltaic panel 1 can contact the liquid de-icing agent. In this way, the use of the liquid de-icing agent can prevent the surface of the photovoltaic panel 1 from freezing, and even if floating ice is generated, it will be shoveled off by the snow shoveling belt 22, and the outflowing liquid de-icing agent will also flow back into the storage box 30 for repeated use.
