Groundwater mining system

Abstract

The invention provides a groundwater mining system which comprises a water taking device, a fixed station, an ultrasonic water level meter, a lifting structure, a shield body, a lifting rod, a controller and a power supply; the water taking device comprises an electromagnetic relay, a water taking pipeline and a water pump; the electromagnetic relay comprises a relay coil, a relay normally-closedcontact and an electromagnetic valve; the lifting structure on the fixed station controls the lifting rod to move in an observation well, and the lifting structure stops after moving to the preset distance; the ultrasonic water level meter monitors the distance from the lifting rod to the groundwater surface, transmits the distance to the controller in real time, and presets the allowable mining range in the controller; when the groundwater level exceeds the preset range, the controller controls the relay coil to be electrified, the relay normally-closed contact is disconnected, the electromagnetic valve is powered off and disconnected, the water taking pipeline is disconnected to stop water pumping from groundwater, and the water pump stops working. The groundwater mining system effectively prevents excessive groundwater mining and reasonably utilizes the groundwater resource.

Description

technical field [0001] The invention relates to the technical field of groundwater exploitation equipment, in particular to a groundwater exploitation system. Background technique [0002] The shortage of water resources has become a serious problem that threatens the survival of human beings. In this case, saving water has become an urgent social problem. Due to the shortage of water resources, the overexploitation of groundwater is common, and the water environment problems caused by it are becoming more and more serious, which has a serious negative impact on the sustainable development of economy and the sustainable utilization of water resources. However, at present, apart from manual measurement, there is no other effective way to effectively prevent the over-exploitation of groundwater. Contents of the invention [0003] In order to solve the technical problem that the excessive exploitation of groundwater cannot be controlled in the prior art, the purpose of the e...
