Abstract

The invention provides an automatic draining device of a gas extraction system. The automatic draining device comprises a water collecting box, a piston switch device, a first one-way valve and a second one-way valve, wherein the water collecting box is provided with a first connector, a second connector, a water inlet and a water outlet; the piston switch device is arranged in the water collecting box and comprises a piston cylinder body, a piston rod and a floating ball; a cavity body is formed in the piston cylinder body; the piston cylinder body is provided with a first opening, a second opening, a third opening and a fourth opening; the first opening is connected with the first connector; the second opening is connected with the second connector; a first blocking part and a second blocking part are arranged at one end of the piston rod; and the floating ball is arranged on the piston rod. According to the automatic draining device of the gas extraction system, the defects of low sensitivity and high fault rate caused by a great number of mechanical transmission parts are avoided and the draining effect is improved.

Description

technical field [0001] The invention relates to gas drainage technology, in particular to an automatic water discharge device for a gas drainage system. Background technique [0002] At present, during the gas extraction process of the mine negative pressure drainage system, the seepage water in the coal rock formation is often pumped into the gas drainage pipeline of the gas drainage system. resistance, and directly affects its continuous gas extraction effect, which poses a great threat to the safe production of mines. In the prior art, a lever mechanical automatic water release device is usually used to discharge the accumulated water in the gas drainage system. The lever mechanical automatic water release device uses the buoyancy of the water to realize the positive and negative pressure conversion of the tank through the lever transmission to complete the water release. However, the lever mechanical automatic water release device has many mechanical transmission parts...
