Photovoltaic module conservative shelf with automatic sealing mechanism

The invention discloses a photovoltaic module conservative frame with an automatic sealing mechanism, relates to the technical field of photovoltaic module protection equipment, and aims to solve the problems that a conservative frame is not favorable for rapid protection installation, a metal conservative frame is high in overall manufacturing cost and use cost, the whole photovoltaic module is easily impacted and vibrates in hail or rainstorm, and the conservative frame is inconvenient to use. A transmission shaft drives a transmission belt to rotate, at the moment, the transmission belt pulls a connecting rod to move so as to drive a protection piece to move, meanwhile, the transmission shaft can drive a winding shaft to conduct synchronous unwinding, and finally the protection piece is completely laid on the upper surface of a photovoltaic panel. Rainwater, hail, gravel and air garbage cannot directly fall onto the photovoltaic panel, the photovoltaic panel is protected, the service life of the photovolta
