Description

Technical Field

[0001] This utility model relates to the field of snow and ice removal for photovoltaic panels, specifically a snow and ice removal device for a photovoltaic cleaning robot. Background Technology

[0002] Currently, with the rapid development of the photovoltaic power generation industry, the photovoltaic power generation industry has become a new trend in the domestic and foreign power generation industry due to its advantages such as environmental protection and high energy quality. However, since the photovoltaic panels used in photovoltaic power generation are usually installed outdoors, the snowfall in winter will cover the photovoltaic panel surface, which will greatly affect the conversion efficiency of the photovoltaic module. Therefore, it is necessary to clear the snow from the photovoltaic panel of the photovoltaic module.

[0003] Existing methods for removing snow and ice from photovoltaic panels using brushes can only remove snow from the surface. When the panel surface is covered with ice, the brushes cannot remove the ice, and snow remains on the surface after brushing. This necessitates multiple snow removal operations, significantly reducing the efficiency of snow removal from photovoltaic panels. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a snow and ice removal device for a photovoltaic cleaning robot. This solves the technical problem that the current method of removing snow and ice from the surface of photovoltaic panels by brushing can only clean the snow on the surface of the photovoltaic panels. When the surface of the photovoltaic panels is frozen, the brush cannot clean the ice on the surface of the photovoltaic panels, and there is still snow on the surface of the photovoltaic panels after the brush is cleaned. Therefore, multiple snow removals are required for the photovoltaic panels, which greatly reduces the efficiency of snow removal from the photovoltaic panels.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: designing a snow and ice removal device for a photovoltaic cleaning robot, including an inverted U-shaped frame, with a brush roller rotatably connected between the two sides of the inner cavity of the inverted U-shaped frame via a rotating shaft, a first motor installed at one end of the outer side of the inverted U-shaped frame, the drive end of the first motor being connected to the rotating shaft on the brush roller, a connecting plate connected to one end of the inverted U-shaped frame, a cleaning block installed at one end of the connecting plate, a semi-circular groove opened at one end of the cleaning block near the inverted U-shaped frame, and one end of the semi-circular groove being open, and a rubber shovel plate installed on the lower side of the semi-circular groove near the inverted U-shaped frame;

[0006] An inverted L-shaped plate is installed at one end of the inverted U-shaped frame. A second motor is installed on the inner side of the inverted L-shaped plate and at the end of the inverted U-shaped frame away from the inverted L-shaped plate. The drive end of the second motor rotates through the inverted U-shaped frame and is connected to a walking wheel.

[0007] Preferably, a drive shaft is rotatably connected to one end of the inner cavity of the semicircular groove, and a spiral conveying blade is connected to the outer side of the drive shaft. The spiral conveying blade is fitted against the inner wall of the semicircular groove. One end of the drive shaft rotatably passes through the semicircular groove and is positioned on the outer side of the cleaning block. A driven sprocket is connected to the drive shaft on the outer side of the cleaning block. A drive sprocket is installed on the outer side of the drive end of the second motor on the inner side of the inverted L-shaped plate. A chain connects the drive sprocket and the driven sprocket.

[0008] Preferably, a hot air blower is installed at the top of the inner cavity of the inverted U-shaped frame, an air guide pipe is installed between the two sides of the inner cavity of the inverted U-shaped frame, multiple air outlets are opened at the bottom of the air guide pipe, and a connecting pipe connects the air outlet of the hot air blower to the air guide pipe.

[0009] Preferably, the bottom of the inverted U-shaped frame is provided with connecting columns on both sides, and the bottom of the two connecting columns is rotatably connected to limit wheels.

[0010] Preferably, an adjustment groove is provided on one side of the bottom of the inverted U-shaped frame, and an adjustment block is slidably connected in the adjustment groove. The adjustment block is connected to one of the connecting columns. A lead screw is rotatably connected to one side of the inner cavity of the adjustment groove, and one end of the lead screw rotatably passes through the adjustment block and the adjustment groove and is placed on the outside of the inverted U-shaped frame. A handwheel is installed on the lead screw on the outside of the inverted U-shaped frame, and the adjustment block is threaded onto the outside of the lead screw.

[0011] Preferably, a solar panel is installed on the top of the inverted U-shaped frame, and batteries are installed on both sides of the top of the inner cavity of the inverted U-shaped frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines an inverted U-shaped frame, a first motor, a brush roller, a cleaning block, and a semi-circular groove. By starting the first motor, the brush roller rotates, thereby sweeping away snow from the surface of the photovoltaic panel. As the cleaning block moves with the inverted U-shaped frame, it works in conjunction with the rubber shovel to remove the snow and ice from the photovoltaic panel and accumulate it in the semi-circular groove. Since the photovoltaic panel is tilted during use, when a certain amount of snow and ice accumulates in the semi-circular groove, the removed snow and ice are discharged from the photovoltaic panel through the opening at one end of the semi-circular groove due to gravity, thus quickly cleaning the snow and ice from the surface of the photovoltaic panel and further improving the efficiency of snow and ice removal from the photovoltaic panel surface.

[0014] 2. This utility model combines a second motor, a spiral conveyor blade, a drive sprocket, a driven sprocket, and a chain. When the first motor drives the walking wheel to rotate and moves the cleaning robot, the drive sprocket, driven sprocket, and chain work together to drive the spiral conveyor blade to rotate. The rotation of the spiral conveyor blade can help push the ice and snow accumulated in the semi-circular groove to be discharged, thus avoiding the effect of ice and snow cleaning on the surface of the photovoltaic panel when a large amount of ice and snow accumulates in the semi-circular groove.

[0015] 3. This utility model combines a hot air blower, connecting pipe, air duct, and air outlet. When clearing ice and snow, the hot air blower is activated to generate hot air, which is then sprayed out through the air outlet to melt and loosen the ice and snow on the surface of the photovoltaic panel. This makes it easier for the rubber scraper to remove the snow from the surface of the photovoltaic panel. Furthermore, the water generated by melting reduces the friction between the ice and snow and the inner wall of the semi-circular groove, further facilitating the discharge of ice and snow from the semi-circular groove.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A snow and ice removal device for a photovoltaic cleaning robot, see [link / reference] Figures 1 to 3The system includes an inverted U-shaped frame 1. A brush roller 11 is rotatably connected between the two sides of the inner cavity of the inverted U-shaped frame 1 via a rotating shaft. A first motor 12 is mounted on one outer end of the inverted U-shaped frame 1, and the drive end of the first motor 12 is connected to the rotating shaft on the brush roller 11. A connecting plate 2 is connected to one end of the inverted U-shaped frame 1, and a cleaning block 21 is mounted on one end of the connecting plate 2. A semi-circular groove 22 is formed on the end of the cleaning block 21 near the inverted U-shaped frame 1, and one end of the semi-circular groove 22 is open. A rubber spatula 25 is mounted on the lower side of the semi-circular groove 22 near the end of the inverted U-shaped frame 1. An inverted L-shaped plate 4 is mounted on one end of the inverted U-shaped frame 1. A second motor 41 is mounted on the inner side of the inverted L-shaped plate 4 and on the end of the inverted U-shaped frame 1 away from the inverted L-shaped plate 4. The drive ends of the second motors 41 are both rotated... The inverted U-shaped frame 1 is connected to the traveling wheels 42. During operation, the second motor 41 is started to drive the traveling wheels 42 to rotate, thereby moving the inverted U-shaped frame 1 on the surface of the photovoltaic panel. At the same time, the first motor 12 is started to drive the brush roller 11 to rotate, thereby sweeping the snow on the surface of the photovoltaic panel. Since the cleaning block 21 moves with the inverted U-shaped frame 1, it works with the rubber shovel 25 to remove the ice and snow from the surface of the photovoltaic panel and make the ice and snow accumulate in the semi-circular groove 22. Since the photovoltaic panel is tilted during use, when a certain amount of ice and snow accumulates in the semi-circular groove 22, the removed ice and snow will be discharged from the photovoltaic panel through the opening at one end of the semi-circular groove 22 due to gravity, thereby quickly cleaning the ice and snow on the surface of the photovoltaic panel and further improving the efficiency of ice and snow cleaning on the surface of the photovoltaic panel.

[0022] For details, see Figure 2 One end of the inner cavity of the semicircular groove 22 is rotatably connected to a drive shaft 23. A spiral conveying blade 24 is connected to the outer side of the drive shaft 23, and the spiral conveying blade 24 is fitted against the inner wall of the semicircular groove 22. One end of the drive shaft 23 rotatably passes through the semicircular groove 22 and is placed on the outer side of the cleaning block 21. A driven sprocket 72 is connected to the drive shaft 23 on the outer side of the cleaning block 21. An active sprocket 7 is installed on the outer side of the drive end of the second motor 41 on the inner side of the inverted L-shaped plate 4. A chain 71 is connected between the active sprocket 7 and the driven sprocket 72. When the first motor 12 drives the walking wheel 42 to rotate and move the cleaning robot, the active sprocket 7, the driven sprocket 72, and the chain 71 work together to drive the spiral conveying blade 24 to rotate. The rotation of the spiral conveying blade 24 can help push the ice and snow accumulated in the semicircular groove 22 out, thus avoiding the effect of cleaning ice and snow on the surface of the photovoltaic panel when a large amount of ice and snow accumulates in the semicircular groove 22.

[0023] Further, see Figure 2A hot air blower 61 is installed at the top of the inner cavity of the inverted U-shaped frame 1, and an air guide pipe 6 is installed between the two sides of the inner cavity of the inverted U-shaped frame 1. Multiple air outlets 62 are opened at the bottom of the air guide pipe 6. A connecting pipe 63 connects the air outlet of the hot air blower 61 to the air guide pipe 6. When clearing ice and snow, the hot air blower 61 is started to generate hot air, which is then sprayed out through the air outlet to melt and loosen the ice and snow on the surface of the photovoltaic panel. This makes it easier for the rubber scraper 25 to remove and clean the snow on the surface of the photovoltaic panel. In addition, the water generated by melting reduces the friction between the ice and snow and the inner wall of the semi-circular groove 22, further facilitating the discharge of ice and snow from the semi-circular groove 22.

[0024] It is worth noting that, see Figure 2 and Figure 3 The inverted U-shaped frame 1 has connecting posts 5 on both sides of its bottom. The bottom of each of the two connecting posts 5 is rotatably connected to a limiting wheel 51. An adjustment groove 52 is opened on one side of the bottom of the inverted U-shaped frame 1. An adjustment block 53 is slidably connected in the adjustment groove 52. The adjustment block 53 is connected to one of the connecting posts 5. A lead screw 54 is rotatably connected to one side of the inner cavity of the adjustment groove 52. One end of the lead screw 54 rotatably passes through the adjustment block 53 and the adjustment groove 52 and is placed on the outside of the inverted U-shaped frame 1. A handwheel 55 is installed on the lead screw 54 on the outside of the inverted U-shaped frame 1. The adjustment block 53 is threaded on the outside of the lead screw 54. The limiting wheel 51 can limit the robot to both sides of the photovoltaic panel, thereby improving the stability of the cleaning robot moving on the photovoltaic panel. Furthermore, by turning the lead screw 54, the distance between the limiting wheels 51 on both sides can be easily adjusted, which facilitates the assembly and disassembly of the cleaning robot.

[0025] It is worth noting that, see Figure 1 A solar panel 3 is installed on the top of the inverted U-shaped frame 1, and batteries 31 are installed on both sides of the top of the inner cavity of the inverted U-shaped frame 1. A solar controller is connected between the solar panel 3 and the batteries 31. The batteries 31 are connected to the first motor 12, the second motor 41 and the hot air blower 61 through an inverter. The batteries 31 are charged by the solar panel 3, so as to provide power to the first motor 12, the second motor 41 and the hot air blower 61.
