Photovoltaic assembly cracking prevention device

The utility model relates to the technical field of photovoltaic assemblies and particularly relates to a photovoltaic assembly cracking prevention device. The photovoltaic assembly cracking prevention device comprises a foundation, a support board, at least one pressure rod and a rod sleeve, wherein the foundation is hinged with one end of the support board, one end of the rod sleeve is hinged on the foundation, one ends of the pressure rods are hinged at the back face of the support board, the other ends of the pressure rods stretch into the rod sleeve, the pressure rods are provided with shaft shoulders, the pressure rods are provided with pressure springs, one ends of the pressure springs are fixedly connected with the shaft shoulders, the other ends of the pressure springs are fixedly connected with the rod sleeve, the pressure rods are three, the middle portion of the support board is provided with one of the pressure rods, and two top angle portions at the upper end of the back face of the support board are respectively provided with one of the pressure rods. According to the photovoltaic assembly cracking prevention device, a photovoltaic assembly is mounted on the support board, the pressure springs are arranged between the support board and a support, wind power can be effectively buffered through the pressure springs, wind power born by the photovoltaic assembly is relieved by the pressure springs, an original hard contact mounting mode is replaced by a mode having the buffering function, and thereby an assembly aluminum framework is prevented from being torn by heavy wind.
