[0002] A solar greenhouse uses solar energy to convert solar radiation energy into heat energy, providing suitable temperature and lighting conditions that are conducive to plant growth. In a solar greenhouse, solar energy enters the greenhouse through greenhouse covering materials (such as glass, polyethylene film, etc.), is absorbed and converted into heat energy, raising the temperature inside the greenhouse. In rainy and snowy weather in winter, since the top of the solar greenhouse is horizontal or slightly inclined glass, snow is easy to accumulate on the top of the solar greenhouse, blocking the light of the solar greenhouse.

[0003] The patent with patent number CN218205300U discloses a simple snow remover, including a snow removal plate, one end of the snow removal plate is fixedly connected to a first baffle, the other end of the snow removal plate is fixedly connected to a second baffle, the bottom of the snow removal plate is fixedly connected to a snow scraper strip, the middle part of the top of the snow removal plate is fixedly connected to one end of the telescopic rod, the middle part of the telescopic rod is fixedly connected to a supporting wheel, one end of the top of the snow removal plate is fixedly connected to one end of the first support rod, the other end of the first support rod is fixedly connected to one side of the telescopic rod, the other end of the top of the snow removal plate is fixedly connected to one end of the second support rod, and the other end of the second support rod is fixedly connected to the other side of the telescopic rod. The patent has a simple structure, is easy to use, saves time and effort, can timely and effectively remove snow remaining on the plastic film, avoid a large amount of snow crushing the greenhouse frame, causing damage to crops and reduced production, causing serious economic losses, and achieving the purpose of snow disaster prevention and mitigation facilities.

[0004] However, the current simple snow remover has the following problems: when the simple snow remover is in use, the snow on the roof of the solar greenhouse accumulates for a long time and freezes on the roof of the solar greenhouse. When the solar greenhouse roof made of polyethylene film or glass is scraped off with force, the polyethylene film or glass is easily scratched, which can easily cause damage to the solar greenhouse roof, resulting in the simple snow remover scratching the solar greenhouse roof when clearing the snow, causing damage to the solar greenhouse. Therefore, we propose an automatic snow removal device based on the roof of the solar greenhouse and a method for using it. Summary of the invention

The L-shaped chamfered strip 9 scrapes off the frozen snow during the reciprocating swing. The rubber cap 10 on the L-shaped chamfered strip 9 rests on the polyethylene film or glass during the reciprocating swing, so as to prevent the automatic snow removal device from scratching the roof of the solar greenhouse and causing damage to the solar greenhouse during automatic clearing.

[0022] Two vertical blocks 11 are fixed to the front of the U-shaped plate 8, and the two vertical blocks 11 are respectively located at the top and bottom of the front of the U-shaped plate 8. Arc-shaped spring sheets 12 are fixed on both sides of the front of the two vertical blocks 11. The four arc-shaped spring sheets 12 are located on the back sides of the two L-shaped chamfered strips 9. Two baffles 13 are fixed to the back sides of the four arc-shaped spring sheets 12.

[0025] See also Figure 1-Figure 8On the basis of the above embodiment, another embodiment of the present invention further includes an ice-breaking and wiping device 5 and a snow-blocking device 6. The ice-breaking and wiping device 5 is arranged on the back of the inner wall of the U-shaped plate 8. The ice-breaking and wiping device 5 includes a vertical plate 51, a T-shaped plate 52, a plurality of protrusions 53, two arc-shaped spring strips 54, two U-shaped long frames 55 and two sponge rollers 56. The vertical plate 51 is fixed on the back of the inner wall of the U-shaped plate 8. The vertical plate 51 is located in the middle of the U-shaped plate 8. The T-shaped plate 52 is hinged on the back of the vertical plate 51. The plurality of protrusions 53 are fixed on the back of the T-shaped plate 52. The two arc-shaped spring strips 54 are fixed on the left and right sides of the vertical plate 51. The two U-shaped long frames 55 are fixed on the side of the two arc-shaped spring strips 54 away from the vertical plate 51. The two sea sponge rollers 56 are fixed on the side of the two arc-shaped spring strips 54 away from the vertical plate 51. The sponge rollers 56 are rotatably mounted on the inner walls of the two U-shaped long frames 55, a torsion spring is arranged between the T-shaped plate 52 and the vertical plate 51, a plurality of protrusions 53 are arranged to be made of stainless steel, the outer walls of the two sponge rollers 56 are arranged to be rough surfaces, the two sponge rollers 56 are arranged on the movement trajectory of the T-shaped plate 52, the two sponge rollers 56 are arranged to be higher than the back side of the U-shaped plate 8, the protrusions 53 break the thin ice on the roof of the solar greenhouse to prevent the accumulation of thin ice on the roof of the solar greenhouse, and the T-shaped plate 52 will lightly hit the sponge roller 56 during the process of reciprocating left and right swinging, and the T-shaped plate 52 will knock the broken ice on the sponge roller 56 off, so as to avoid the thin ice adhering to the equipment when the automatic snow removal device is cleaning the accumulated water, resulting in poor effect of the equipment in cleaning the accumulated water.

[0026] The ice-breaking and wiping device 5 also includes two vertical bars 57, two arc-shaped spring plates 58 and two vertical rods 59. The two vertical bars 57 are fixed on the back side of the inner wall of the U-shaped plate 8, the two arc-shaped spring plates 58 are fixed on the back side of the two vertical bars 57, and the two vertical rods 59 are fixed on the side of the two arc-shaped spring plates 58 away from the vertical bars 57. The two vertical rods 59 are both on the movement trajectory of the two sponge rollers 56. Under the elastic force of the arc-shaped spring plates 58, the vertical rods 59 squeeze the sponge rollers 56 that are full of water, and the sponge rollers 56 discharge the absorbed accumulated water, thereby avoiding the sponge rollers 56 being full of water when the automatic snow removal device is cleaning the accumulated water, resulting in poor cleaning effect.

[0027] A snow blocking device 6 is provided at the top of the front side of the U-shaped plate 8, and the snow blocking device 6 includes a rectangular block 61, a sliding column 62, two L-shaped plates 63 and two rubber rings 64. The rectangular block 61 is fixed at the top of the front side of the U-shaped plate 8, and a sliding groove is provided inside the U-shaped plate 8. The sliding column 62 is slidably installed on the inner wall of the sliding groove of the U-shaped plate 8, and the two L-shaped plates 63 are fixed at the left and right sides of the sliding column 62. The two rubber rings 64 are fixed in the middle of the opposite surfaces of the two L-shaped plates 63. During the reciprocating movement of the L-shaped plate 63 to the left and right, the thicker snow is blocked and pushed to both sides, so as to prevent the automatic snow removal device from causing damage to the equipment due to the thicker snow falling on the equipment during snow removal.

[0028] The snow blocking device 6 also includes a square plate 65, two discs 66, two short columns 67 and two round head blocks 68. The square plate 65 is fixed in the middle of the top surface of the rectangular block 61, the two discs 66 are fixed above the opposite surfaces of the two L-shaped plates 63, the two short columns 67 are fixed in the middle of the opposite surfaces of the two discs 66, and the two round head blocks 68 are fixed on the opposite surfaces of the two short columns 67. When the L-shaped plate 63 blocks the accumulated snow, the L-shaped plate 63 vibrates to shake off the accumulated snow, thereby preventing the accumulated snow from accumulating on the L-shaped plate 63 during the process of the automated snow removal device blocking the snow, resulting in poor snow blocking effect.

[0029] When the U-shaped plate 8 reciprocates left and right, the U-shaped plate 8 drives the vertical plate 51 to swing back and forth, and the vertical plate 51 drives the T-shaped plate 52 to swing back and forth. Under the action of gravity, the T-shaped plate 52 swings back and forth on the vertical plate 51, and the T-shaped plate 52 drives the protrusion 53 to swing back and forth. The protrusion 53 breaks the thin ice on the roof of the sunshine greenhouse to prevent the thin ice from accumulating on the roof of the sunshine greenhouse. At the same time, the vertical plate 51 drives the arc spring strip 54 to swing back and forth, and the arc spring strip 54 drives the U-shaped long frame 55 to swing back and forth, and the U-shaped long frame 55 drives the sponge roller 56 to swing back and forth. Under the elastic force of the arc spring strip 54, the sponge roller 56 on the U-shaped long frame 55 is tightly attached to the roof of the greenhouse. Under the action of friction, the sponge roller 56 rolls to wipe off the accumulated water on the roof of the greenhouse. At the same time, the T-shaped plate 52 will slightly hit the sponge roller 56 during the reciprocating swing. The T-shaped plate 52 will knock the broken ice on the sponge roller 56 off, preventing the sponge roller 56 from being attached to the sponge roller 56 when clearing the accumulated water on the greenhouse roof, thereby avoiding the problem of thin ice adhering to the equipment when the automatic snow removal device is cleaning the accumulated water, resulting in poor water cleaning effect of the equipment.

[0030] While the U-shaped long frame 55 drives the sponge roller 56 to swing back and forth, the vertical bar 57 supports the arc-shaped spring plate 58, and the arc-shaped spring plate 58 supports the vertical rod 59. In the process of the sponge roller 56 moving back and forth, the sponge roller 56 contacts the vertical rod 59. When the sponge roller 56 rolls on the roof of the greenhouse, the vertical rod 59 squeezes the sponge roller 56 that is full of water under the elastic force of the arc-shaped spring plate 58. The sponge roller 56 discharges the absorbed accumulated water to prevent the accumulated water from accumulating in the sponge roller 56, thereby avoiding the problem of poor water cleaning effect caused by the sponge roller 56 being full of water when the automatic snow removal device is cleaning the accumulated water.

[0031] When the U-shaped plate 8 reciprocates left and right, the U-shaped plate 8 drives the rectangular block 61 to reciprocate left and right, and the rectangular block 61 drives the sliding column 62 to reciprocate left and right. Under the action of gravity, the sliding column 62 slides back and forth in the rectangular block 61, and the sliding column 62 drives the L-shaped plate 63 to reciprocate left and right. The L-shaped plate 63 drives the rubber ring 64 to reciprocate left and right. In the process of the rubber ring 64 reciprocating left and right, the rubber ring 64 contacts the rectangular block 61 to prevent the L-shaped plate 63 from being pressed against the rubber ring 64. When the L-shaped chamfered strip 9 scrapes off the thick snow at a high place, the thick snow will fall down onto the equipment. The L-shaped plate 63 will block the thick snow and push the snow to both sides during the reciprocating movement to prevent the thick snow from falling onto the equipment when the equipment is automatically scraping snow, thereby avoiding the problem of the automatic snow removal device causing the thick snow to fall onto the equipment and causing the equipment to fall and be damaged.

[0032] While the sliding column 62 drives the L-shaped plate 63 to move back and forth left and right, the rectangular block 61 supports the square plate 65, the L-shaped plate 63 drives the disc 66 to move back and forth left and right, the disc 66 drives the short column 67 to move back and forth left and right, and the short column 67 drives the round head block 68 to move back and forth left and right. In the process of the round head block 68 moving back and forth left and right, the round head block 68 will hit the square plate 65, and the round head block 68 will produce a strong vibration amplitude, and the round head block 68 will transmit the vibration to the L-shaped plate 63, so that when the L-shaped plate 63 blocks the accumulated snow, the L-shaped plate 63 vibrates to shake off the accumulated snow, preventing the accumulated snow from accumulating in the L-shaped plate 63, thereby avoiding the problem of poor snow blocking effect caused by the accumulation of snow on the L-shaped plate 63 during the snow blocking process of the automatic snow removal device.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
