DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative work belong to the scope of the utility model.

[0026] As Figures 1-4As shown, in the embodiment of the present application, the motor 202 is arranged on one side of the top end of the fixed frame 1, and a protective sleeve 201 is arranged outside the motor 202. The bottom end of the protective sleeve 201 is connected to the top end of the fixed frame 1. Sliding grooves 210 are arranged on one side of the left and right ends of the fixed frame 1. Threaded rods 203 and sliding rods 208 are respectively arranged in the sliding grooves 210. The sliding rods 208 are arranged on the inner walls of the sliding grooves 210 at both ends. One end of the threaded rod 203 is arranged on the inner wall of the sliding groove 210, and the other end penetrates to the outer surface of the fixed frame 1. Specifically, during the use of the photovoltaic crystal plate 102, dust and other impurities may exist on the surface due to the influence of the weather. Therefore, it is necessary to clean the photovoltaic crystal plate 102 to reduce the influence of dust and other impurities on the absorption of solar energy by the photovoltaic crystal plate 102. To this end, we use double-row scrapers 205 to clean the surface of the photovoltaic crystal plate 102. The double-row scrapers 205 need to be driven by the U-shaped plate 209. Therefore, the motor 202 needs to be used. The protective sleeve 201 outside the motor 202 is used to protect the motor 202. The exposed part of the protective sleeve 201 is located below, which can heat dissipation for the motor 202, and at the same time, it can block the wind and rain. The threaded rod 203 is rotatably arranged on the inner wall of the sliding groove 210 of the fixed frame 1, and the sliding rod 208 is fixedly arranged on the inner wall of the sliding groove 210 of the fixed frame 1.

The outer wall of the threaded rod 203 is provided with a threaded seat 204. The outer wall of the sliding rod 208 is provided with a sliding sleeve 207. The threaded seat 204 and the sliding sleeve 207 are filled in the inner wall of the sliding groove 210. The bottom end of each is provided with a fixed plate 206. The top end of the fixed plate 206 is provided with a U-shaped plate 209. The U-shaped plate 209 is semi-surrounded on the outer surface of the fixed frame 1. The bottom end of the U-shaped plate 209 is provided with a double-row scraper 205. The bottom end of the double-row scraper 205 is in contact with the surface of the photovoltaic crystal plate 102. Specifically, when the double-row scraper 205 is used to clean the surface of the photovoltaic crystal plate 102, the motor 202 drives the threaded rod 203 to rotate. The threaded seat 204 arranged on the outer wall of the threaded rod 203 is limited in the sliding groove 210, which can limit the movement direction of the threaded seat 204. The threaded rod 203 drives the threaded seat 204 to translate during rotation. The threaded seat 204 can drive the U-shaped plate 209 to move through the fixed plate 206 during movement. The U-shaped plate 209 drives the sliding sleeve 207 on the other side to slide on the sliding rod 208 through the fixed plate 206 during movement. The U-shaped plate 209 can drive the double-row scraper 205 to clean the surface of the photovoltaic crystal plate 102 during movement. The bottom end of the double-row scraper 205 abuts against the surface of the photovoltaic crystal plate 102, which can clean and remove the impurities on the surface, thereby increasing the area of the photovoltaic crystal plate 102 in contact with sunlight. In this embodiment, the U-shaped plate 209 mainly relies on the threaded rod 203 to drive translation, but it can still be replaced by a guide rail or a sliding rail. Since the guide rail and the sliding rail are prior art, they will not be described in detail here.
