Detailed Description

Referring to fig. 1 and 2, in an embodiment of the present invention, an automatic cleaning system for a photovoltaic module includes a support column 1, a connecting frame 2 is disposed on the support column 1, a plurality of photovoltaic panels 4 are disposed on two sides of the connecting frame 2, adjacent photovoltaic panels 4 are hinged to each other by a hinge 5, sliding grooves 6 are disposed in front of and behind the photovoltaic panel 4 located at the outermost side, sliding grooves 6 are disposed in front of and behind the photovoltaic panel 4 located in the middle at intervals of one photovoltaic panel 4, and a cleaning brush 7 is slidably disposed between two sliding grooves 6 of the same photovoltaic panel 4.

In this embodiment, the middle part that 2 both sides of link span correspond every row of photovoltaic board 4 is equipped with flexible loop bar 3 respectively, the end of flexible loop bar 3 is articulated with the photovoltaic board 4 of the most side that corresponds. The length of hinge 5 slightly is less than the diameter of cleaning brush 7, that is to say, can make photovoltaic board 4 expand or shrink through the flexible of flexible loop bar 3, and when photovoltaic board 4 shrink, cleaning brush 7 that is located the corresponding of photovoltaic board 4 in the middle of can laminate with two adjacent photovoltaic boards 4 to can clear up two photovoltaic boards 4 simultaneously, and because tend to perpendicularly when photovoltaic board 4 shrinks, the dust on the photovoltaic board 4 of being convenient for drops to ground.

In this embodiment, the positions of the two sides of the connecting frame 2 corresponding to the middle of the two telescopic rods 3 are respectively provided with a scissor connecting rod 8, the scissor connecting rod 8 is formed by hinging two sides of multiple X-shaped sleeves, the middle part of the scissor connecting rod 8 is hinged to one end of each sliding groove 6 uniformly, and each photovoltaic panel 4 is provided with a gap through which the scissor connecting rod 8 can pass. Under the action of the scissor connecting rod 8, the photovoltaic panels 4 on the same side can be uniformly and synchronously unfolded or contracted, and the cleaning brush 7 can be uniformly attached to the two adjacent photovoltaic panels 4.

In this embodiment, the front and the back of the connecting frame 2 are respectively provided with a friction belt 11 capable of rotating in an annular manner, and two ends of the cleaning brush 7 are fixed with friction wheels 9. When the friction wheel 9 is jointed with the friction belt 11, the friction belt 11 can drive the friction wheel 9 to rotate.

In the embodiment, the friction belt 11 is connected to a lifting frame 10, and an electric telescopic cylinder I12 is arranged in the lifting frame 10. Through the height that electric telescopic cylinder 12 can change friction area 11, can change the height of cleaning brush 7 through the height that changes friction area 11 when friction pulley 9 and friction area 11 laminating, make cleaning brush 7 can clear up the different positions of photovoltaic board 4.
