Wave-preventing air sac leakage detecting device and wave-preventing air sac leakage detecting system of tank truck

Abstract

The invention relates to the technical field of wave-preventing air sac leakage proofing of a tank truck, in particular to a wave-preventing air sac leakage detecting device and wave-preventing air sac leakage detecting system of the tank truck. Structurally, a pressure sensor and a temperature sensor are utilized to detect an air pressure value and an air temperature value in a wave-preventing air sac in real time, whether the wave-preventing air sac leaks or not is comprehensively judged according to the air pressure value and the air temperature value, and effectiveness and reliability of the wave-preventing air sac leakage detecting system are effectively improved. Meanwhile, in a wave-preventing air sac leakage detecting method, leakage is judged by calculating a molar volume value of air and detecting change of the molar volume value. Since the molar volume value in direct proportion to air volume in the wave-preventing air sac and is free of influence by other factors, the detecting result is accurate and low in error, whether the wave-preventing air sac leaks or not can be effectively detected, and reliability of the wave-preventing air sac is improved.

Description

technical field [0001] The present application relates to the field of anti-leakage technology of liquid tanker anti-wave airbags, in particular to a leakage detection device and detection method of liquid tanker anti-wave airbags. The method is completed by establishing a functional module framework and controlling a computer system by computer program instructions. Background technique [0002] A liquid tank truck is a special vehicle for transporting liquids, which includes a liquid tank carrying liquid. During the travel of the liquid tank truck, the liquid in the liquid tank will generate surges due to its fluidity, and the impact of the surge on the tank wall It will cause the vehicle to run unstable and affect the safety of the tank truck. For this reason, wave-resistance devices are added to liquid tank trucks to reduce the generation of surges. Most of the existing wave blocking devices are made of hard materials. This blocking device not only has a large weight, b...

AI Technical Summary

Problems solved by technology

[0004] In the existing design, the wave breaking airbag generally keeps its volume unchanged after being inflated. ) material problems, there will inevitably be the possibility of leakage

If the wave breaking air bag leaks during transportation, it will cause: (1) The air pressure of the wave breaking air bag is insufficient, so that it cannot be effectively attached to the liquid surface in the liquid tank, and the wave breaking air bag loses its wave blocking effect; (2) Since the liquid tank is For a closed tank, the gas leakage in the wave arresting airbag will increase the pressure on the tank wall and damage the strength of the tank

For this reason, after the liquid tank is filled with liquid, it is necessary to detect in real time whether the wave breaking air bag leaks. However, since the wave breaking air bag is installed in a sealed liquid tank, it is impossible to directly judge whether the wave breaking air bag leaks. Affected by the gas temperature, if you only rely on the air pressure in the airbag to judge whether the airbag is leaking, you cannot accurately judge whether the airbag is leaking, and the detection error is large
