Manhole well leakage measuring sensor

Abstract

The invention discloses a manhole well leakage measuring sensor. The manhole well leakage measuring sensor comprises a conducting polymer bar sensitive to carbureted hydrogen, a first floating ball liquid level detection assembly, a second floating ball liquid level detection assembly and a controller; the first floating ball liquid level detection assembly and the second floating ball liquid level detection assembly each comprise a floating ball and a switch element triggered when encountering the liquid to float upwards, the first floating ball liquid level detection assembly is arranged atthe bottom end of the manhole well leakage measuring sensor, the second floating ball liquid level detection assembly is arranged above the first floating ball liquid level detection assembly by the preset distance, and the controller is electrically connected with the conducting polymer bar, the floating ball liquid level detection assembly and the second floating ball liquid level detection assembly. The manhole well leakage measuring sensor can ensure oil tank manhole well condition all-weather real-time monitoring, compared with manual work, oil tank manhole well seepage and leakage can befound in time, environment pollution and economic losses can be prevented, liquid seepage can be distinguished to be water or oil, and the serious results can be avoided.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a leak detection sensor for manhole wells. Background technique [0002] The manhole well is on the oil tank of the gas station, which is used for manual operation to measure the oil level, monitor the pipeline and other use space. When the rainy season comes or a sudden rainstorm, it is often easy to accumulate water in the manhole well of the gas station. If the long-term accumulated water is not treated in time, it may seep into the oil tank. When the water level at the bottom of the oil tank reaches a certain height, the accumulated water will be sucked away by the fuel dispenser, mixed with the oil and added to the fuel tank, causing the vehicle to stall and break down, causing customer complaints. Especially in some areas in the south, the accumulation of water in oil tanks has become a problem that has plagued the station owners for many years. [0003] GB50156-2012 "Cod...
