[0002] Electric vehicle charging devices are dedicated facilities that provide charging services for electric vehicles. They are usually located in residential areas, units, public places and other places. The design of the charging shed is to provide electric vehicle users with a safe and convenient charging environment, and it can also play a certain role in beautifying the community environment. Charging sheds are usually equipped with safety facilities such as fire protection and lightning protection to reduce potential safety hazards during charging. The charging shed is equipped with multi-functional charging sockets that can support the charging needs of various types of electric vehicles. Users can easily park their electric vehicles in the shed and connect the charger for charging. As electric vehicles have become the main choice for people's short-distance travel, the construction of charging sheds will help solve the problem of electric vehicle charging and further promote the development and popularization of electric vehicles.

Dust and other debris will reduce the light transmittance of the photovoltaic panel surface and reduce the absorption of sunlight. The accumulation of dust on the surface of the photovoltaic panel is equivalent to reducing the illuminated area, which directly affects the photovoltaic module's ability to capture sunlight, thereby reducing power generation efficiency. According to actual measurements, dust may cause a loss of solar radiation of 5% to 30%. Summary of the invention

The charging plug board is connected to the city power supply.

When charging the battery vehicle, the input end of the electric vehicle charger is inserted into the charging plug board, and the output end of the charger is inserted into the charging port of the electric vehicle for charging.

[0028] like Figure 2-4As shown, the erasing mechanism is installed above the rain shelter 102, and the erasing mechanism includes a scraper 303, one side of the scraper 303 can be against the photovoltaic panel 2, and only one side of the scraper 303 can contact the photovoltaic panel 2. The erasing mechanism drives the scraper 303 to move, and when the scraper 303 moves to both sides of the rain shelter 102, it drives the scraper 303 to flip. The erasing mechanism includes a motor 301 fixedly installed on the rain shelter 102, a reciprocating screw 3 rotatably installed on both sides of the rain shelter 102, a driving block 302 threadedly connected to the reciprocating screw 3, a sector tooth 304 rotatably installed on the driving block 302, a first rack 305 fixedly installed on one side of the rain shelter 102, and a second rack 306 fixedly installed on the other side of the rain shelter 102. The scraper 303 is installed between the two sector teeth 304, and the output shaft of the motor 301 is fixedly connected to one of the reciprocating screws 3. A linkage belt 307 is installed on one side of the two reciprocating screw rods 3, and the linkage belt 307 drives the two reciprocating screw rods 3 to rotate synchronously. When removing debris from the photovoltaic panel, the starting motor 301 drives the reciprocating screw rod 3 to rotate, and the transmission of the linkage belt 307 drives the two reciprocating screw rods 3 to rotate synchronously, thereby driving the driving block 302 to move, and the driving block 302 drives the sector teeth 304 to move, thereby driving the scraper 303 to move, so that the scraper 303 scrapes the dust and debris on the photovoltaic panel 2, when the sector teeth 304 moves to the position of the second rack 306, the second rack 306 will drive the sector teeth 304 to rotate, thereby driving the scraper 303 to flip, and the flipped scraper 303 will not contact the photovoltaic panel 2, when the sector teeth 304 moves to the position of the first rack 305, the first rack 305 will drive the sector teeth 304 to rotate, thereby driving the scraper 303 to flip again, at this time The scraper 303 contacts the photovoltaic panel 2 again, and the dust on the photovoltaic panel 2 is cleaned again with the rotation of the reciprocating screw rod 3.

[0029] like Figure 1-2 and Figure 5As shown, the cleaning mechanism is installed on one side of the rain shield 102, and the cleaning mechanism cleans the stains on the scraper 303 after the overturning. The cleaning mechanism includes a water tank 4 fixedly installed on the base 1, a water pump 401 and an air pump 402 fixedly installed on the water tank 4, a mounting plate 403 fixedly installed on one side of the rain shield 102, and multiple groups of nozzles fixedly installed on the mounting plate 403.

Cleaning liquid is provided in the water tank 4, and the cleaning liquid dissolves the stains on the scraper 303. When the second rack 306 drives the scraper 303 to flip, the side of the scraper 303 that can contact the photovoltaic panel 2 will face the air blowing nozzle 404 and the water spray nozzle 405. At this time, the water pump 401 is started, and the cleaning liquid in the water tank 4 is sprayed onto the scraper 303 at a high speed through the water spray nozzle 405 to remove the stains on the scraper 303. Then, the water pump 401 is turned off and the air pump 402 is started. The scraper 303 is air-dried through the air blowing nozzle 404, and the impurities that are difficult to remove on the scraper 303 can be removed. Then, the scraper 303 can clean the photovoltaic panel again.

[0030] Working principle: When removing debris from the photovoltaic panel, the starting motor 301 drives the two reciprocating screws 3 to rotate synchronously, thereby driving the scraper 303 to move, so that the scraper 303 scrapes the dust and debris on the photovoltaic panel 2. When the sector teeth 304 move to the position of the second rack 306, the second rack 306 will drive the sector teeth 304 to rotate, thereby driving the scraper 303 to flip. After flipping, the side of the scraper 303 that can contact the photovoltaic panel 2 will face the air blowing nozzle 404 and the water spray nozzle 405. At this time, the water pump 401 is started to spray the cleaning liquid in the water tank 4 onto the scraper 303 at a high speed through the water spray nozzle 405, so as to clean the scraper 303. The stains are cleaned, and then the water pump 401 is turned off and the air pump 402 is started. The scraper 303 is air-dried through the air blowing nozzle 404, and the impurities that are difficult to remove on the scraper 303 can be cleaned. At this time, the scraper 303 will not contact the photovoltaic panel 2. With the rotation of the bidirectional screw rod 3, the scraper 303 moves to the other side of the awning 102. When the sector tooth 304 moves to the position of the first rack 305, the first rack 305 will drive the sector tooth 304 to rotate, thereby driving the scraper 303 to flip again. At this time, the scraper 303 contacts the photovoltaic panel 2 again, and with the rotation of the reciprocating screw rod 3, the dust on the photovoltaic panel 2 is cleaned again.
