[0035] Also includes a rubber pad 21, see Figure 1 As shown, rubber pads 21 are fixedly connected in the middle of the left and right sides of the outer bottom of the mounting frame 1.

[0036] First, the operator puts the photovoltaic component into the placement rack 2 for use. When there are impurities and dust on the photovoltaic component, the driving mechanism 4 is started, and the driving mechanism 4 operates to drive the lifting mechanism 5 to operate. The lifting mechanism 5 operates to drive the placement rack 2 to swing upward, and the placement rack 2 swings upward to drive the photovoltaic component and the brush roller 31 to swing upward. When the photovoltaic component swings upward to a suitable position, the photovoltaic component is in an inclined state. Due to the effect of gravity, the brush roller 31 swings downward and contacts the photovoltaic component, and the brush roller 31 removes impurities and dust on the photovoltaic component. The driving mechanism 4 is turned off, and the driving mechanism 4 stops driving the lifting mechanism 5. The lifting mechanism 5 stops driving the placement rack 2 to swing upward, and the placement rack 2 stops driving the photovoltaic component to swing upward. At this time, the impurities and dust on the photovoltaic component are also cleaned up, and the driving mechanism 4 is started again to drive the lifting mechanism 5 to operate and reset. The lifting mechanism 5 operates and resets to drive the placement rack 2 to swing downward and reset, and the placement rack 2 swings downward and resets to drive the photovoltaic component to swing downward and reset, and the driving mechanism 4 is turned off, and the brush roller 31 is pulled to move rightward and reset. The brush roller 31 resets and removes impurities and dust on the photovoltaic component again.

The rack 2 swings upward, and the photovoltaic component stops swinging upward. Due to the effect of gravity, the brush roller 31 moves to the left to remove impurities and dust on the photovoltaic component. When the impurities and dust on the photovoltaic component are removed, the servo motor 41 is started to reverse. The servo motor 41 reverses and drives the screw rod 43 to reverse through the transmission assembly 42. The screw rod 43 reverses and drives the lifting mechanism 5 to operate and reset. The lifting mechanism 5 operates and resets to drive the rack 2 to swing downward and reset. The placement rack 2 resets and drives the photovoltaic component to swing downward and reset. The servo motor 41 is turned off, and the screw rod 43 stops driving the lifting mechanism 5 to operate, and the rack 2 also stops driving the photovoltaic component to swing downward.

[0038] When the servo motor 41 starts to rotate forward, the screw rod 43 rotates forward through the thread to drive the moving block 51 to move rightward. The moving block 51 moves rightward and drives the lower part of the first telescopic rod 52 to swing rightward. The lower part of the first telescopic rod 52 swings rightward so that the upper part swings leftward. The upper part of the first telescopic rod 52 swings leftward and drives the hinge seat 53 to swing upward. The hinge seat 53 swings upward and drives the placement rack 2 to swing upward. The placement rack 2 also drives the photovoltaic module to swing upward. The photovoltaic module and the placement rack 2 are in an inclined state. The servo motor 41 is turned off and the servo motor 41 stops. The transmission assembly 42 drives the screw rod 43 to rotate forward, the screw rod 43 stops driving the moving block 51 to move right, the moving block 51 stops driving the lower part of the first telescopic rod 52 to swing right, the upper part of the first telescopic rod 52 also stops driving the hinged seat 53 to swing left, the hinged seat 53 stops driving the placement rack 2 to swing upward, the placement rack 2 stops driving the photovoltaic module to swing upward, because the photovoltaic module and the placement rack 2 are in an inclined state, due to the effect of gravity, the brush roller 31 swings downward and contacts the photovoltaic module, and the brush roller 31 removes impurities and dust on the photovoltaic module. When all the impurities and dust on the photovoltaic module are cleaned up, the servo motor 41 is started to reverse, the screw rod 43 is reversed, and the moving block 51 is driven to move to the left and reset through the thread. The moving block 51 moves to the left and resets, driving the lower part of the first telescopic rod 52 to swing to the left and reset. The lower part of the first telescopic rod 52 swings to the left and resets, causing the upper part to swing to the right and reset. The upper part of the first telescopic rod 52 swings to the right and resets, driving the placement rack 2 to swing downward and reset through the hinged seat 53.

Figure 1 , Figure 6 and Figure 7As shown, a water storage tank 78 is installed on the right side of the bottom of the mounting frame 1 by welding, and a nozzle 79 is connected in the middle of the lower part of the front and rear sides of the water storage tank 78, and the tail ends of the front and rear nozzles 79 face the placement frame 2. When water is discharged into the nozzle 79, the nozzle 79 can spray water out, and a vertical rod 74 is symmetrically rotated in the front and rear right side of the top of the mounting frame 1. The bottom ends of the front and rear vertical rods 74 respectively rotate to penetrate the lower parts of the front and rear nozzles 79, and the lower parts of the front and rear vertical rods 74 are installed with spiral plates 76 by welding.

[0042] When the servo motor 41 starts to rotate forward, the placement rack 2 swings upward, driving the photovoltaic assembly to swing upward. At the same time, the placement rack 2 swings upward and also drives the shaft 3 to reverse. The reversal of the shaft 3 drives the acceleration assembly 61 to reverse. The reversal of the acceleration assembly 61 drives the rotating rod 62 to reverse. The reversal of the rotating rod 62 drives the first winding wheel 66 to reverse. The first winding wheel 66 reverses to reel in the pull wire 67. The rewinding of the pull wire 67 drives the front sliding block 68 to move rightward. The front first spring 611 is stretched. The front sliding block 68 moves rightward, driving the front second telescopic rod 69 to move rightward. The cleaning wheel 610 moves to the right, and the cleaning wheel 610 moves to the right, driving the second telescopic rod 69 on the rear side to move to the right. The second telescopic rod 69 on the rear side moves to the right, driving the rear sliding block 68 to move to the right, and the first spring 611 on the rear side is stretched.

The cleaning wheel 610 moves to the right and contacts the photovoltaic module. The cleaning wheel 610 removes impurities and dust on the photovoltaic module, thereby cleaning the photovoltaic module. When the wheel 610 moves to the right to the maximum stroke, the servo motor 41 is turned off, the placement rack 2 stops driving the photovoltaic module to swing upward, the placement rack 2 stops driving the shaft 3 to reverse, the shaft 3 stops driving the rotating rod 62 to reverse through the acceleration component 61, the rotating rod 62 stops driving the first winding wheel 66 to reverse, the pull wire 67 stops being wound, the pull wire 67 stops driving the front sliding block 68 to move to the right, and the front sliding block 68 also stops driving the cleaning wheel 610 to move to the right through the front second telescopic rod 69.

The front sliding block 68 also stops driving the cleaning wheel 610 to move to the right through the front second telescopic rod 69. At this time, the servo motor 41 is started to reverse, and the placement rack 2 swings downward to drive the photovoltaic assembly to swing downward to reset. At the same time, the placement rack 2 also drives the shaft 3 to rotate forward to reset. The forward rotation of the shaft 3 drives the rotating rod 62 to rotate forward through the acceleration assembly 61. The forward rotation of the rotating rod 62 drives the first winding wheel 66 to rotate forward. The pull wire 67 is loosened. Due to the action of the first springs 611 on the front and rear sides, the sliding blocks 68 on the front and rear sides move to the left to reset and respectively drive the second telescopic rods 69 on the front and rear sides to move to the left to reset. The second telescopic rods 69 on the front and rear sides move to the left to reset and drive the cleaning wheel 610 to move to the left to reset, and the servo motor 41 is turned off. In this way, there is no need for the operator to pull the brush roller 31 to move and reset, and it is more convenient to remove impurities and dust on the photovoltaic assembly.

[0043] First, the operator pours an appropriate amount of water into the water tank 78, and the water in the water tank 78 flows into the front and rear nozzles 79, and the water contacts the front and rear spiral plates 76. When the servo motor 41 starts to rotate forward, the front and rear sliding blocks 68 move to the right and drive the cleaning wheel 610 to move to the right through the front and rear second telescopic rods 69. When the front and rear sliding blocks 68 move to the right and contact the front and rear magnetic blocks 71 respectively, the front and rear magnetic blocks 71 fix the front and rear sliding blocks 68 by magnetic force, and then after the impurities and dust on the photovoltaic components are cleaned, the front and rear sliding blocks 68 are The movable block 68 moves to the left and resets, driving the front and rear magnetic blocks 71 to move to the left, the front and rear second springs 72 are stretched, the front and rear magnetic blocks 71 move to the left, driving the front and rear pull ropes 73 to move to the left, the front and rear pull ropes 73 move to the left and drive the front and rear second winding wheels 75 to rotate, the front and rear volute springs 77 are compressed, the front and rear second winding wheels 75 rotate and drive the front and rear vertical rods 74 to rotate, the front and rear vertical rods 74 rotate and drive the front and rear spiral plates 76 to rotate, the front and rear spiral plates 76 rotate and drive the water to move upward, and the water continues to move upward. When the second springs 72 on the front and rear sides are stretched to the maximum stroke, the magnetic blocks 71 on the front and rear sides stop moving to the left, the magnetic blocks 71 on the front and rear sides stop driving the pull ropes 73 on the front and rear sides to move to the left, the pull ropes 73 on the front and rear sides stop driving the second winding wheels 75 on the front and rear sides to rotate, the second winding wheels 75 on the front and rear sides stop driving the spiral plates 76 on the front and rear sides to rotate through the vertical rods 74 on the front and rear sides, and the spiral plates 76 on the front and rear sides stop transporting water. The sliding block 68 continues to move to the left to reset, and the front and rear sliding blocks 68 are out of contact with the front and rear magnetic blocks 71. Due to the action of the front and rear second springs 72, the front and rear magnetic blocks 71 move to the right to reset, so that the front and rear pull ropes 73 are loosened. Due to the action of the front and rear volute springs 77, the front and rear second winding wheels 75 rotate in the opposite direction to reset, and the front and rear second winding wheels 75 also rewind the front and rear pull ropes 73 to reset. At the same time, the front and rear second winding wheels 75 rotate in the opposite direction to drive the front and rear spiral plates 76 to rotate in the opposite direction to reset through the front and rear vertical rods 74.
