Portable pressure regulating and measuring device for underground water exploration and drainage

Abstract

The invention discloses a portable pressure regulating and measuring device for underground water exploration and drainage. The device comprises a high-pressure oil pipe, a water passing pipeline anda drainage pipeline which are connected through the high-pressure oil pipe, a pup joint sleeve is arranged to connect the water passing pipeline and the high-pressure oil pipe, the drainage pipeline is connected with the high-pressure oil pipe through a high-pressure oil pipe connector, and the drainage pipeline leads to a drainage ditch. A water pressure measuring mechanism is arranged at one side of the pup joint sleeve, and the signal output end of a core control mechanism is connected with the signal input end of the water pressure measuring mechanism; a water pressure adjusting mechanismis further arranged in the drainage pipeline, the signal output end of the core control mechanism is connected with the signal input end of the water pressure adjusting mechanism, a communication serial port of an information processing mechanism is connected with the core control mechanism, and the signal output end of the core control mechanism is connected with the signal input end of the waterpressure measuring mechanism; and the water pressure measuring mechanism is connected with the communication serial port of the information processing mechanism through the core control mechanism. According to the scheme, pressure measurement can be facilitated, and timely and non-stop pressure regulation can be completed.

Description

technical field [0001] The invention belongs to the field of coal mine underground water exploration and discharge equipment, and more specifically, the invention relates to a portable pressure regulating and pressure measurement device for underground mine water exploration and discharge. Background technique [0002] Nowadays, when the water pressure needs to be measured during the coal mine exploration and discharge, the traditional method is to first manually close the high-pressure gate valve in the drainage pipe, install a dull plate connected to the pressure gauge on the high-pressure gate valve, and then open the gate valve to read the pressure gauge. After the displayed pressure is measured, close the gate valve manually, remove the dull plate after pressure relief, and then open the gate valve to release water. [0003] There are many problems in this kind of traditional method: the operation steps are cumbersome, and each step needs to be manually operated, which ...

AI Technical Summary

Problems solved by technology

[0003] There are many problems in this kind of traditional method: the operation steps are cumbersome, and each step needs to be manually operated, which is time-consuming and labor-intensive; once the misoperation is easy to cause injury accidents, the safety cannot be guaranteed; the timely measurement of the water pressure is too large, and the pressure cannot be adjusted in time. It is necessary to stop the drainage work, and then carry out emergency treatment, and the work efficiency is low; it is impossible to record every measurement data
