Abstract

The invention relates to a technique for automatic drainage of seeper in the gas pumping and vent pipeline in coal mine, which can be adopted for automatic drainage of seeper in pipeline under a plurality of high or negative pressure condition. This invention realizes the storage and drainage of water by opening and closing the cap door of a water discharging device with a gas distribution device; the gas distribution is realized by realizing the upward and downward movement at two conditions of fully filled water and vacancy via a floating ball and a balance weight floating ball, then, pushing a lever to move upwards and downwards and a guide rod is driven to push the left and right movement of a slide block, thus realizing the connection of the device with the air and the pumping and discharging pipeline as well as the movement for water discharge and water storage.

Description

The making of gas drainage under suction pipeline tailrace

The technical field present technique relates to discharge automatically in the coal mine gas extraction pipeline technology of ponding, is fit to the technology that all kinds of high negative pressure state lower pipelines are outwards emitted ponding automatically.

The existing automatic water drainage device of background technology is the float bowl-type tailrace, utilize buoyancy, magnet and deadweight interoperation, realize that tailrace inside is with the folding of atmosphere and extraction pipeline, thereby realize the process of automatic draining, manufacture craft is comparatively complicated, under the high negative pressure state, need bigger buoyancy and counterweight, we realize the distribution of tailrace inside by the principle control slide block movement that utilizes lever, process with the automatic draining of realizing tailrace, the air distributing device batch production of can finalizing the design, technology is simple, is easier to realize normal water storage and the process that discharges water under the high negative pressure state.

The summary of the invention present technique is finished these performances from following link: two states moves up and down when realizing in the device the full and emptying of water by ball float and counterweight ball float, the promotion lever moves up and down and drives guide rod promotion slide block move left and right, and the interior conducting with atmosphere and extraction pipeline of realization device reaches the action that discharges water with water storage.

The description of drawings concrete structure is seen the tailrace schematic diagram.

Fig. 1 is for after discharging water, under the effect of the counterweight ball float of bottom lever move down that the band movable slider moves to left will be logical big The aperture sealing of gas with the little bore closure of sensible atmosphere, and is opened the aperture that leads to extraction pipeline, and is open to atmosphere The lid door that discharges water is closed under suction function, and the device internal gas pressure is with the extraction pipeline balance, and the lid door of extraction pipeline is opened Action discharges water. 1 is: the lid door; 2 for sliding fast; 3 is ball float; 4 is the counterweight ball float.

Fig. 2 be in the device water long-pending full after, under the ball float effect on top on the lever shipper pole movable slider move to right, with the little bore closure of sensible extraction pipeline, and open open to atmosphere aperture, under suction function, the lid door that discharges water of pipeline is closed, and the open to atmosphere lid door that discharges water is opened normally and discharged water.1 is: the lid door; 2 for sliding fast; 3 is ball float; 4 is the counterweight ball float.

Fig. 3 for discharge water or ponding after, ball float promotes the intermediateness of the sliding fast motion of guide rod traction.1 is: the lid door; 2 for sliding fast; 3 is ball float; 4 is the counterweight ball float.

The specific embodiment mainly is distributing valve and ball float and counterweight ball float motion cooperation, and the distributing valve slide block should seal also to be wanted and can normally slide, and while sliding distance and ball float move distance are complementary and get final product.

Claims

1. utilize the mode of distribution to realize the switching of the lid door of tailrace container, thereby it communicated with extraction pipeline or atmosphere, realize tailrace automatic water-storing, discharge water

2. utilize lever to realize promoting the amplification of slide block power.
