Automatic water discharge device

Abstract

The invention provides an automatic water discharge device which comprises a shell, an end cover, a long guide rod, a water inlet device, a water discharge device and a ventilation device, wherein the end cover is arranged on the top of the shell; the water inlet device is positioned on the end cover and is communicated with the shell; one end of the long guide rod is arranged in a guide sleeve in a sliding way, and the other end of the long guide rod is provided with a plugging block; the guide sleeve is fixedly arranged at the bottom in the shell; the rod diameter of the long guide rod is sequentially and fixedly provided with a high-position cotter pin and is sheathed with a floating block in a sliding way; the water discharge device is arranged at the outer side close to the bottom ofthe shell, and is communicated with the shell; when the long guide rod rises, a water discharge switch device arranged on the long guide rod also rises along with the long guide rod, so that the water discharge device can be started; and when the water inlet device is plugged by the plugging block, a ventilation switch device arranged on the long guide rod is used for starting the ventilation device arranged on the end cover, so that the water can be automatically discharged. The automatic water discharge device realizes the aim of automatically discharging seepage.

Description

technical field [0001] The invention relates to the technical field of coal engineering, in particular to an automatic water discharge device with a filtering device. Background technique [0002] At present, in the process of negative pressure gas extraction in mines, the seepage water in the coal formation is often pumped into the gas drainage pipe of the gas drainage system. The seepage water not only increases the resistance of the gas drainage pipe, but also It directly affects the effect of its continuous gas extraction, and also poses a great threat to the safe production of mines. In the prior art, the seepage water entering the gas drainage pipe is often discharged manually, but it is not only time-consuming and labor-intensive, but also difficult to remove the seepage water and impurities that have entered the gas drainage pipe in time.
