Cracking-resistant device for photovoltaic module

The invention relates to the technical field of photovoltaic modules, in particular to a cracking-resistant device for a photovoltaic module. The cracking-resistant device comprises a base, a supporting plate, at least one pressure lever and a rod sleeve, wherein the base is hinged to one end of the supporting plate; one end of the rod sleeve is hinged to the base; one end of each pressure lever is hinged to the back of the supporting plate; the other end of each pressure lever extends in the rod sleeve; a shaft shoulder is arranged on each pressure lever; a pressure spring is arranged on each pressure lever; one end of each pressure spring is fixedly connected with the corresponding shaft shoulder; the other end of each pressure spring is fixedly connected with the rod sleeve; the number of the pressure levers is three; one pressure lever is arranged at the middle of the supporting plate; the two pressure levers are respectively arranged at two vertical angles at the upper end of the back of the supporting plate. According to the cracking-resistant device for the photovoltaic module, disclosed by the invention, the photovoltaic module is mounted on the supporting plate; the pressure springs are arranged between the supporting plate and a bracket; the wind force can be effectively buffered by the pressure springs, so that the wind force borne by the photovoltaic module is relived by the pressure springs; the original hard contact mounting mode is improved into a mode with a buffer function, so that potential hazard that an aluminum frame of the module is torn by gale is effectively avoided.
