when the illumination angle changes, namely when illumination is gradually displaced from eastern to western, at this time, the sun can be displaced towards the top end of the photovoltaic panel 1, at this time, the valve of the electromagnetic directional valve 13 can be opened, the valve direction of the electromagnetic directional valve 13 is controlled to be outwards conducted and inwards cut off, at this time, rainwater in the water storage tank 7 can enter the temporary storage pipe 14 through the electromagnetic directional valve 13, and external pressure is applied to the piston panel 15, at this time, the piston panel 15 and the piston rod 16 are displaced backwards along with the temporary storage pipe, at this time, the reset spring 17 is compressed, the piston rod 16 and the reinforcing plate 21 are driven to be displaced backwards, at this time, under the action of the reinforcing plate 21, the two first fixing seats 10 can be driven to be displaced backwards, the first fixing seats 10 are displaced relative to the first fixing guide rail 8 under the action of the clamping block 9, at this time, the first fixing seats 10 are outwards conducted and inwards moved along with the temporary storage pipe 11 are outwards deflected along with the temporary storage pipe, at this time, the interval between the photovoltaic panel 1 and the first fixing guide rail 8 is changed, the photovoltaic panel 1 is outwards deflected relative to the fixing base 2, at this time, the included angle between the photovoltaic panel 1 and the fixing base 2 is reduced, at this time, the photovoltaic panel 1 is controlled to be in the state of being close to the temporary storage pipe 1, the internal state of the temporary storage pipe is controlled to the temporary storage pipe 1, and the temporary storage pipe is reset, namely, the water storage pipe 1 is reset, at this time, the internal angle is controlled to be in the state, and the internal state is changed, and the internal state, when the angle is changed, when the angle is in the internal state, and is in the state, and is opposite, when the condition is opposite, and is controlled, and is turned, and has been turned, and when the condition, and has been in the condition, and has been turned;
when dust and dirt exist on the surface of the photovoltaic panel 1 and normal power generation of the photovoltaic panel 1 is affected, rainwater can be input into the power tank 195 through the cleaning box 191 by opening a valve positioned in the first communicating pipe 193, and can be input into the water spraying box 192 through the second communicating pipe 194 at the bottom end of the power tank 195, at the moment, the spray head at the bottom end of the water spraying box 192 can start spraying the rainwater from the spray head and acts on the surface of the photovoltaic panel 1, the rainwater enters the power tank 195 and simultaneously pushes the impeller 196 to rotate, the main shaft 197 rotates, the torsion spring 198 is in a compressed state, the storage disc 199 rotates, the traction rope 1910 on the outer side winds, at the moment, the guide block 1911 can be pulled to move upwards, at the moment, the guide block 1911 can move upwards relative to the second fixed guide rail 20, the two guide blocks 1911 can synchronously move upwards, at the moment, the surface of the photovoltaic panel 1 can be cleaned by matching with the sprayed rainwater at the spray head and the displacement of the cleaning soft brush 1912, at the same time, backflow of the sewage can be effectively prevented, when the rainwater is automatically used up, the rainwater 1910 automatically rotates, the traction rope 1912 is reset, the cleaning brush is driven from top to bottom, and the cleaning position is restored to the original position.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
