Abstract

This utility model discloses a safety monitoring device for a high-pressure hydrogen storage tank, including a base, a mounting frame, a protective shell assembly, a cooling assembly, a hydrogen storage tank assembly, and a monitoring assembly. The mounting frame is fixedly connected to the upper side of the base, and the protective shell assembly is located on the upper side of the mounting frame. In this utility model, through the inclusion of a pressure sensor, a dissolved hydrogen measuring instrument, an adjusting rod, and an adjusting ring, the device can monitor the hydrogen content in the cooling water using the dissolved hydrogen measuring instrument and monitor the pressure inside the heat-insulating protective shell using the pressure sensor. This allows for timely detection of hydrogen leaks. Simultaneously, the rotatable adjusting rod drives the adjusting ring to move left and right, enabling the ultrasonic guided wave monitoring module, temperature sensor, and strain sensor to comprehensively monitor the high-pressure hydrogen storage tank. This device provides comprehensive safety monitoring of the high-pressure hydrogen storage tank, eliminating monitoring blind spots and improving the accuracy of safety monitoring.
