Embodiment 1

[0059] The working process of the drainer is as follows:

[0060] (1) The water storage stage of the water release device:

[0061]When the water release device just started to store water, the torque at the lever counterweight end was greater than the torque at the inner bucket end, and the inner bucket was lifted to the highest position. Now the water inlet valve compression spring is in the minimum compression state, and the water inlet is in the maximum open state, while the water discharge valve compression spring is in the maximum compression state, and the water discharge valve ball is tightly pressed to seal the water discharge port. The water in the gas extraction pipeline flows into the inner barrel from the water inlet through the drain hose.

[0062] As the amount of water in the inner bucket gradually increases, the weight of the inner bucket end continues to increase. When the torque at the inner bucket end is greater than that at the counterweight end, the leve...

Embodiment 2

[0070] On the basis of the above-mentioned embodiment 1, the water dispenser is provided with a time delay device and a time delay cone.

[0071] (1) The water storage stage of the water release device:

[0072] Such as figure 2 In the shown state, when the water is just stored, the moment at the lever balance weight end is greater than the moment at the inner barrel end, and the inner barrel is lifted to the highest position. At this time, the water storage delay conical pipe can be inserted into the water storage delay device and clamped by the delay device. Now the water inlet valve compression spring is in the minimum compression state, and the water inlet is in the maximum open state, while the water discharge valve compression spring is in the maximum compression state, and the water discharge valve ball is tightly pressed to seal the water discharge port. The water in the gas extraction pipeline flows into the inner barrel from the water inlet through the drain hose....

Embodiment 3

[0082] On the basis of the above-mentioned embodiment 1 and embodiment 2, the water dispenser is provided with a secondary water storage tank.

[0083] Such as image 3 In the state shown, in the water release stage, since the water inlet of the water release device is closed, in order to prevent water accumulation in the gas extraction pipe at this time, the water release device is provided with a secondary water storage tank. In the water release process of the water release device, the water in the gas extraction pipe can enter the secondary water storage tank first, and when the water discharge device water inlet is opened, the water in the secondary water storage tank flows into the inner barrel again.

Abstract

The invention relates to an automatic water discharging device of a coal-mine gas extraction pipeline. The automatic water discharging device of the coal-mine gas extraction pipeline comprises an outer cylinder and an inner cylinder. The inner cylinder is matched with a balancing weight through a lever mechanism so that the inner cylinder can move along a guide rod in a linear mode. When water is stored, a water inlet of the inner cylinder is opened, a water discharge opening is closed, and water in the gas pipeline flows into the inner cylinder; when water accumulated in the inner cylinder reaches a certain quantity, the inner cylinder declines along the guide rod, the water inlet is closed, and the water discharging opening is opened for water discharging. All components are designed in a pure mechanical mode so that safety and explosion resistance can be achieved; elements, prone to damage and pollution, of floats, magnets and the like are not arranged, the guide rod is not in contact with polluted water, and the automatic water discharging device of the coal-mine gas extraction pipeline is durable and high in reliability.

Description

technical field [0001] The invention relates to a water discharge device, in particular to a water discharge device capable of automatically discharging accumulated water in a coal mine gas extraction pipeline. Background technique [0002] Coal mine gas drainage is an important measure to ensure safe production in coal mines. The method of coal mine gas extraction is generally to drill into coal seams and gas accumulation areas, connect the drill holes to special gas extraction pipelines, and use extraction equipment to extract gas from coal seams and goafs. During this process, the liquid water in the coal seam will inevitably enter the drainage pipeline, and the water entering the drainage pipeline will significantly reduce the effective cross-sectional area of ​​the gas drainage pipeline, or even block the pipeline, seriously affecting the gas drainage effect. Therefore, the accumulated water in the drainage pipeline must be discharged in time. [0003] There are many ...
