Abstract
The utility model relates to an underground air leak blocking and draining device of coal mines, comprising mine laneways. The underground air leak blocking and draining device is characterized in that air leak blocking and draining devices are installed at crossed laneways, wherein the air leak blocking and draining device comprises an inner bush and an outer bush, the inner bush is sleeved in the outer bush, the upper end of the outer bush is of an open structure to stretch into an upper laneway, the lower end of the outer bush is of a sealed structure, a sealing liquid layer is filled at the bottom part of the outer bush, the two ends of the inner bush are of open structures, the upper end of the inner bush is stretch into the upper laneway, and the lower end of the inner bush is submerged in the sealing liquid layer of the outer bush. The underground air leak blocking and draining device provided by the utility model can be conveniently installed at the underground overlapped and crossed laneways, water sumps and return airway segments of coal mines to effectively reduce the air leak rate of the coal mines, increase the effective air input of the coal mines and effectively drain the accumulated water in the upper laneways, and the device is simple to manufacture, easy to install and free from manual operation.
Description
Technical field
The utility model relates to leak stopping wind dewatering installation under a kind of coal mine.
Background technology
In mine operation, the ponding in the tunnel needs in time to discharge.At present ponding needs to be provided with water pump and need manually carry out operation in discharge process, because the situation complexity of down-hole, if water pump is set can bring other unfavorable effect, and supernumerary's industry of working not only takies artificial but also security incident can take place.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: leak stopping wind dewatering installation under a kind of coal mine that can overcome above-mentioned defective is provided, be used for the ponding of brattice way conveniently is discharged to the below, the fresh air in tunnel, bottom is revealed to brattice way.
Leak stopping wind dewatering installation under the coal mine provided by the utility model, comprise mine laneway, it is characterized in that leak stopping wind dewatering installation is installed at place, intersection tunnel, described leak stopping wind dewatering installation comprises inner sleeve and outer tube, inner sleeve is enclosed within outer tube inside, and outer sleeve upper is that Open architecture probes into brattice way, the lower end sealed construction, outer sleeve bottom is irritated sealed liquid layer, inner sleeve is a both ends open formula structure, and the upper end probes into brattice way, submerges in the sealed liquid layer of outer tube in the lower end.
Described inner sleeve upper end seals by baffle plate with the corresponding position of outer sleeve upper.
Described outer tube bottom has water-guiding hole, and water-guiding hole is concordant with the liquid level of sealed liquid layer.
Sleeve type structure between inner sleeve and the outer tube cooperates water-guiding hole and baffle plate that brattice way ponding is discharged downwards, the fresh air in tunnel, bottom can be leaked to brattice way again.
The beneficial effect that the utility model had is: can be installed in tunnel and sump and return airway location overlapping under the coal mine, that intersect easily, can effectively reduce the air leak rate of air curtain of mine, increase the effective wind rate of mine, can effectively discharge simultaneously the ponding of brattice way again, and make simple, easily install, do not need manually-operated.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1, inner sleeve; 2, outer tube; 3, baffle plate; 4, water-guiding hole; 5, sealed liquid layer.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Leak stopping wind dewatering installation under the coal mine as shown in Figure 1, comprise mine laneway, leak stopping wind dewatering installation is installed at place, intersection tunnel, and described leak stopping wind dewatering installation comprises inner sleeve 1 and outer tube 2, and inner sleeve 1 is enclosed within outer tube 2 inside, outer tube 2 upper ends probe into brattice way for Open architecture, the lower end sealed construction, it is both ends open formula structure that the filling of outer tube 2 bottoms has sealed liquid layer 5, inner sleeve 1, the upper end probes into brattice way, submerges in the sealed liquid layer 5 of outer tube 2 in the lower end.The corresponding position in inner sleeve 1 upper end and outer tube 2 upper ends is by baffle plate 3 sealings.Outer tube 2 bottoms have water-guiding hole 4, and water-guiding hole 4 is concordant with the liquid level of sealed liquid layer 5.
Operating principle:
During use, the ponding of brattice way can flow in the outer tube 2 by inner sleeve 1, because outer tube 2 bottoms are hermetically-sealed construction, ponding goes up by the liquid level of sealed liquid layer 5 and in time flows to the tunnel, bottom by water-guiding hole 4, accomplishes in time brattice way ponding to be discharged.The fresh wind in tunnel, bottom enters water-guiding hole 4 backs and is upwards sealed by baffle plate 3, can prevent that therefore the fresh air in tunnel, bottom from upwards revealing.
Sleeve type structure between inner sleeve 1 and the outer tube 2 cooperates water-guiding hole 4 and baffle plate 3 that brattice way ponding is discharged downwards, the fresh air in tunnel, bottom can be leaked to brattice way again.
Claims (3)
1. leak stopping wind dewatering installation under the coal mine, comprise mine laneway, it is characterized in that leak stopping wind dewatering installation is installed at place, intersection tunnel, described leak stopping wind dewatering installation comprises inner sleeve and outer tube, inner sleeve is enclosed within outer tube inside, and outer sleeve upper is that Open architecture probes into brattice way, the lower end sealed construction, outer sleeve bottom is irritated sealed liquid layer, inner sleeve is a both ends open formula structure, and the upper end probes into brattice way, submerges in the sealed liquid layer of outer tube in the lower end.
2. leak stopping wind dewatering installation is characterized in that under the coal mine according to claim 1, and described inner sleeve upper end seals by baffle plate with the corresponding position of outer sleeve upper.
