Leakage detection sensor for fuel dispenser chassis

Abstract

The invention discloses a leakage detection sensor for a fuel dispenser chassis. The leakage detection sensor comprises conducting polymer bars sensitive to carbureted hydrogen, a photoelectric liquid-level probe and a controller; the photoelectric liquid-level probe is arranged at the bottom end of the leakage detecting sensor for the fuel dispenser chassis; and the controller is electrically connected with the conducting polymer bars and the photoelectric liquid-level probe. The leakage detection sensor for the fuel dispenser chassis is capable of guaranteeing all-weather real-time monitoring on the condition of the fuel dispenser chassis; compared with manual labor, the leakage detection sensor is capable of discovering the leakage of the fuel dispenser chassis more timely to prevent environmental pollution and economic losses, and is capable of distinguishing whether leakage liquid is oil or water; moreover, leakage detection is not single-point detection, and thus, full-range detection on the conducting polymer bars can be realized; the leakage detection sensor can also react to trace fuel floating in water, which plays a role of monitoring; and the leakage detection sensor not only is capable of detecting the leakage liquid but also can play a detection function on oil gas of gasoline.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a tanker chassis leak detection sensor. Background technique [0002] The tanker chassis is installed under the tanker to provide operating space and secondary anti-leakage protection for the oil inlet pipeline, emergency shut-off valve and underground pipeline joints in the tanker. The presence of oil in the dispenser chassis may indicate oil leaks in the dispenser, pipes, joints, etc. Regardless of whether the tanker itself leaks or the pipeline leaks, it may cause soil and groundwater pollution, and may even lead to serious accidents such as explosions and fires. However, the liquid in the tanker chassis installed at the bottom of the tanker is not easy to be found, and the hidden danger of pollution and harm are very great.
