[0002] As a renewable and clean energy, solar photovoltaic has become an important force in today's global energy transformation. Snow easily accumulates on the surface of solar panels in winter. If it is not cleaned in a timely, scientific and professional manner, it can cause the power generation of the components to decay by up to 40% to 60%, and the power generation to drop by 20% to 30%.

The first moving wheel group 208 rotates to drive the driven wheel group 218 to rotate through the first connecting rod 219.

[0063] The power output shaft (not shown) of the second motor 303 rotates to drive the fourth gear 213 to rotate, the fourth gear 213 rotates to drive the chain 216, the chain 216 drives the two first gears 210 and the fifth gear 215 to rotate, the first gear 210 rotates to drive the second gear 211 to rotate, the second gear 211 rotates to drive the third gear 212 to rotate, the first gear 210 rotates to drive the third moving wheel group 304 to rotate, the third gear 212 rotates to drive the fourth moving wheel group 305 to rotate, the fifth gear 215 rotates to drive the second roller brush 306 to rotate, and at this time the snow-clearing robot 10 moves on the surface of the photovoltaic component 100.

[0064] When encountering accumulated snow, the snow-clearing robot 10 stops moving. At this time, the electrical control box 202 controls the linear motor 40 to start, and the scraper 53 moves from the lower side to the upper side of the surface of the photovoltaic module 100. The wire ring 52 separates the snow, and the curved surface of the scraper 53 does not scrape the snow. When the scraper 53 moves to the upper side of the surface of the photovoltaic module 100, the accumulated snow has been completely separated. The scraper 53 scrapes the separated snow from the upper side of the surface of the photovoltaic module 100 to the lower side, so that the separated snow is separated from the surface of the photovoltaic module 100. At this time, the snow-clearing robot 10 restarts until the snow-clearing robot 10 encounters snow again and cannot move forward. At this time, the linear motor 40 is started again to sweep the snow.

[0065] The advantage of the present application is that it provides a snow-clearing robot for cleaning snow on the surface of photovoltaic modules. A linear motor and a snow-scraping device are arranged on the top surface of a power vehicle body. A roller brush is also arranged on the bottom surface of the power vehicle body. The power vehicle body can move on the surface of the photovoltaic module. The snow-scraping device can move back and forth along the extension direction of the guide rod of the linear motor, that is, the snow-scraping device can move from one side of the surface of the photovoltaic module to the other side. The snow-scraping device includes a wire ring and a scraper. When the snow-scraping device moves from one end of the guide rod to the other end, the wire ring separates the snow on the surface of the photovoltaic module. When the snow-scraping device returns from the other end of the guide rod, the scraper scrapes the separated snow from the surface of the photovoltaic module. The roller brush on the bottom surface of the power vehicle body performs secondary cleaning on the remaining snow, thereby realizing autonomous cleaning of the snow on the surface of the photovoltaic module and saving manpower and material resources.
