一种矿井出水点封堵设备
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
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.
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.
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.
