Preferably, the wind-up roll is including roll body, pivot and clockwork spring, the both ends of roll body are through pivot and framework swing joint, and be provided with the clockwork spring between the roll body.

Preferably, half of the shielding curtain is a light shielding film, the light shielding part is located on the upper surface of the photovoltaic plate body at low temperature, the other half of the shielding curtain is a light transmitting curtain, and the light transmitting part is located on the upper surface of the photovoltaic plate body at high temperature.

Preferably, one side and the middle part of the control rod are respectively provided with a shape memory alloy section, the shape memory alloy sections are straight-line sections, the shape memory alloy sections are bent by 180 degrees below a certain temperature, and the bending directions of the two shape memory alloy sections are opposite.

The invention has the following beneficial effects:

1. this self-cleaning device of photovoltaic board, under the mating reaction of wind-up roll and control lever, with the temperature trigger action, make and shelter from the automatic activity of curtain, clean the scraper and clear up the spot on it when sheltering from the curtain activity simultaneously, the cleanness of sheltering from the curtain has been guaranteed, make and shelter from the curtain and be in the better situation of printing opacity all the time, on the one hand, because can clear up automatically, the artifical clearance frequency has been reduced by a wide margin, a large amount of water resources and manpower resources have been saved, on the other hand, the manual clearance of low frequency has also reduced direct contact, and then the emergence of wearing and tearing has been reduced, the life of photovoltaic board is improved.

2. This self-cleaning device of photovoltaic board, because the motion state of control lever and wind-up roll is triggered by the temperature, only ambient temperature reaches the definite value and just can trigger the start winter, simultaneously, because the original curtain that shelters from is replaced to the curtain that shelters from that expandes now, guarantees that the surface of sheltering from the curtain does not have sheltering from things such as dew, ice-cube, on the one hand, guarantees the generating efficiency of photovoltaic board, and on the other hand avoids producing the hot spot because sheltering from, guarantees the normal work of photovoltaic board.
