Double-layer oil tank leakage detection sensor

Abstract

The invention discloses a double-layer oil tank leakage detection sensor. The double-layer oil tank leakage detection sensor comprises a conductive polymer strip sensitive to hydrocarbon, a floating ball liquid level detection unit and a controller. The floating ball liquid level detection unit is arranged at the bottom end of a body of the double-layer oil tank leakage detection sensor, and comprises a floating ball and a switch element which can be triggered when the floating ball meets liquid and floats. The controller is electrically connected with the conductive polymer strip and the floating ball liquid level detection unit. With the double-layer oil tank leakage detection sensor, it can be guaranteed that the situation of a double-layer oil tank can be monitored in real time in an all-weather manner, and compared with manual work, leakage of the double-layer oil tank can be found in time better, and environment pollution and economic loss are prevented; the double-layer oil tankleakage detection sensor can identify that leaking liquid is oil or water, and thereby judging that leakage happens to an inner wall or an outer wall; furthermore, the double-layer oil tank leakage detection sensor does not carry out single-point detection, can achieve full-scale detection with the conductive polymer strip, and can further respond to trace oil floating on water to play a role inmonitoring; and the double-layer oil tank leakage detection sensor can not only detect the leaking liquid, and can also play a role in detecting leaking gasoline or oil gas.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a leak detection sensor for a double-layer oil tank. Background technique [0002] At present, the country pays more and more attention to environmental protection, and petrochemical industry is the key field of environmental protection. With the implementation of policies and laws and regulations, more and more double-layer oil tanks have been applied. [0003] The anti-seepage measures and leak detection of double-layer oil tanks are strictly required. GB50156-2012 "Code for Design and Construction of Automobile Refueling and Gas Stations", Chapter 6.1 Oil Tanks, Article 6.1.8 stipulates: The pipe shall meet the requirements of manual detection and on-line monitoring, and shall ensure that any leakage in any part of the inner and outer walls of the oil tank can be found. In Chapter 6.5 anti-seepage measures, Article 6.5.7 stipulates that the leakage detection of double-layer o...
