Device for detecting water content of building block

The utility model discloses a building block water content detection device which comprises a shell, a supporting assembly and a supporting plate, the inner side of the top end of the shell is fixedly connected with a humidity sensor, the inner side of the bottom end of the shell is fixedly connected with a fixing block, the top end of the fixing block is fixedly connected with a double-output-shaft motor, and transmission shafts at the two ends of the double-output-shaft motor are fixedly connected with screw rods. According to the device for detecting the water content of the building block, through components such as a first spring, a second spring, a buckle and a sliding plate, the elastic force of the first spring is convenient for driving two limiting plates to simply limit the building block, and meanwhile, the sliding plate is convenient for supporting and connecting the limiting plates, so that the stability of the limiting plates during movement is improved; and meanwhile, a buckle and a clamping gr
