Abstract

The utility model provides a high-performance liquid leakage sensor, and belongs to the technical field of liquid leakage sensors, the high-performance liquid leakage sensor comprises a flow guide cover, a first connecting pipe is fixedly connected to the lower part of the flow guide cover, a second connecting pipe is fixedly connected to the first connecting pipe, a third connecting pipe is mounted on the second connecting pipe, and a supporting block is welded to the third connecting pipe; a screw rod is rotationally connected to the supporting block, an outer lining is in threaded connection with the outer side of the screw rod, a first connecting plate is installed on the outer lining, a first conducting strip is arranged on the first connecting plate, a sealing assembly is installed on the third connecting pipe, a power source and an alarm lamp are installed on the second connecting pipe, and the positive electrode of the power source is connected with the positive electrode of the alarm lamp. The cathode of the alarm lamp is connected with the second conductive sheet. According to the liquid leakage sensor, the height of the outer lining is adjusted by rotating the screw rod, and then the height of the first conducting strip is changed by utilizing the lifting assembly, so that an alarm lamp is triggered to be turned on at different liquid levels, and the problem that an existing liquid leakage sensor is not suitable for being used in a humid environment is solved.
