Mine water outlet point plugging equipment

By setting up a squeezing chamber and a gas guide pipe outside the extraction pipe, the flow rate of the sealing material is adjusted by using water flow to squeeze the piston plate in the opposite direction, and hot air is generated by a servo motor to accelerate curing. This solves the problem of insufficient injection depth of the mine water outlet sealing equipment under high pressure, and improves the sealing efficiency and reliability.

AI Technical Summary

Technical Problem

Existing mine water outlet sealing equipment suffers from insufficient injection depth and incomplete filling of sealing material under high-pressure water flow conditions, affecting sealing efficiency and effectiveness.

Method used

An extrusion chamber is set outside the extraction pipe. The water flow impacts the piston plate in the opposite direction, automatically adjusting the flow rate of the sealing material to enhance the injection force and depth. Hot air is generated by the air guide pipe and air inlet pipe in conjunction with a servo motor to accelerate the material curing.

Benefits of technology

In high-pressure environments, the injection depth and density of sealing materials can be increased, curing time can be shortened, sealing efficiency and reliability can be improved, and problems of incomplete filling caused by water flow collision can be avoided.

Abstract

The utility model discloses mine water outlet point plugging equipment which comprises an air guide frame and a pumping pipe, the outer side wall of the air guide frame is fixedly connected with an extrusion bin, one end of the pumping pipe penetrates through the extrusion bin and is communicated with a discharging pipe in the air guide frame, the inner side of the extrusion bin is vertically connected with an extrusion plate in a sliding mode, and the bottom of the extrusion bin is communicated with an air guide pipe. Piston frames are arranged on the surfaces of the air guide pipes, and piston plates are slidably connected to the inner sides of the piston frames; the extrusion bin is arranged outside the pumping pipe, when plugging materials are filled, the air guide pipe extends into a plugging crack or hole at the same time, water flow reversely impacts and enters the piston frame to extrude the piston plate, and therefore the extrusion plate is lifted to extrude the pumping pipe, the conveying section is reduced, and the flow speed of the plugging materials is automatically adjusted according to water pressure. The material injection strength and depth are enhanced in a high-pressure environment, the problem of incompact filling caused by water flow hedging is avoided, and the plugging efficiency and reliability are remarkably improved.
