Description
Technical field
The present invention relates to air duct technical field, more particularly to a kind of mining ventilating tunnel drainage arrangement.
Background technology
Industrial air duct is widely used in the underground engineerings such as mine, tunnel, subway, is that a kind of guiding is distinguished and admirable along certain orientation
The flexible duct of flowing, realizes the fresh distinguished and admirable and distinguished and admirable exchange of pollution.Air duct is broadly divided into positive pressure wind pipe and negative pressure air duct, right
In positive pressure wind pipe, particularly in summer and autumn or rainy season, because surface temperature is higher than the damp-heat air in underground chamber temperature, air
Ponding can be formed when being pressed into air duct to the cold；In addition, blower fan placement is unreasonable it is also possible to that directly rainwater is pumped into air duct.
Air duct ponding directly influences the effect of ventilation, firstly reduce the basal area of air duct, adds windage；Secondly, air duct ponding
Air duct can be excessively bent, camber increase equally also increases windage；3rd, air duct ponding reaches a certain amount of air duct that can crush, and makes
The life security of face workman is caused not in time into shut-down, or even ventilation.
Therefore, processing air duct ponding is particularly important, if pulling down air duct cleaning ponding, not only influences project progress,
And tedious process, dismounting repeatedly can also influence the life-span of air duct；If breaking air duct draining, occur that leaks out shows
As, repairing air duct again can reduction air duct significantly quality.
The content of the invention
The invention aims to solve to exist in the prior art, air duct easily sustains damage in drainage procedure lacks
Point, and a kind of mining ventilating tunnel drainage arrangement proposed.
To achieve these goals, present invention employs following technical scheme：
A kind of mining ventilating tunnel drainage arrangement, including air duct body are designed, the air duct body inner bottom part is provided with upper shed, the wind
Cylinder body outer bottom is provided with shed, and the upper shed is connected with shed, and porous plate is provided with the under shed, described many
Orifice plate bottom is provided with catch basin, and the reservoir bases are communicated with drainpipe, and the drainpipe inner top is provided with upper flange, described
Drainpipe inner bottom part is provided with lower flange, and the upper flange bottom surface is provided with the top of annular sealing ring, the lower flange and is provided with spring,
The spring top is connected with ball sealer, and the ball sealer offsets with annular sealing ring, and annular sealing ring bottom surface and ball sealer
Sphere match.
It is preferred that, the cross-sectional area of the under shed is more than the cross-sectional area of upper shed.
It is preferred that, rectangular seal is provided with the top of the porous plate, the porous plate is bolted to be installed on down and opened
It is intraoral.
It is preferred that, catch basin inner bottom surface lowest part into lower recess, and catch basin is connected with drainpipe top.
It is preferred that, the upper flange and lower flange are threadedly coupled with drainpipe respectively.
A kind of mining ventilating tunnel drainage arrangement proposed by the present invention, beneficial effect is：The apparatus structure is simple, user
Just, effectively by rainwater-collecting in catch basin, when the water in catch basin reaches constant weight, pressuring spring shrinks so that
Ball sealer is separated with annular sealing ring, and the rainwater in catch basin flows out out of drainpipe, sealed effect has not been only reached, simultaneously
Also dewatering needs can be met, air duct self structure is not damaged.
Brief description of the drawings
Fig. 1 is a kind of structural representation of mining ventilating tunnel drainage arrangement proposed by the present invention；
Fig. 2 is a kind of catch basin of mining ventilating tunnel drainage arrangement proposed by the present invention and the cross-sectional view of drainpipe.
In figure：Air duct body 1, upper shed 11, under shed 12, porous plate 2, bolt 21, rectangular seal 3, catch basin 4,
Drainpipe 5, upper flange 51, lower flange 52, annular sealing ring 6, ball sealer 7, spring 8.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.
Reference picture 1-2, a kind of mining ventilating tunnel drainage arrangement, including air duct body 1, the inner bottom part of air duct body 1 are provided with and above opened
Mouth 11, the outer bottom of air duct body 1 is provided with shed 12, and upper shed 11 is connected with shed 12, and the cross-sectional area of under shed 12 is big
In being provided with porous plate 2 in the cross-sectional area of upper shed 11, under shed 12, the top of porous plate 2 is provided with rectangular seal 3, porous
Plate 2 is fixedly installed under shed 12 by bolt 21, and porous plate 2 covers under shed 12 with rectangular seal 3 so that rainwater is only
It can prevent rainwater from being flowed out from the outside of porous plate 2, while being fixed by bolt 21 so that square out of porous plate 2 through hole to flowing down
Shape sealing ring 3 suffers oppression compression, improves the sealing of rectangular seal 3 and under shed 12 and porous plate 2.
The bottom of porous plate 2 is provided with catch basin 4, and the bottom of catch basin 4 is communicated with drainpipe 5, and the inner bottom surface of catch basin 4 is to recessed
Fall into, and lowest part is connected with the top of drainpipe 5 in catch basin 4, the inner top of drainpipe 5 is provided with upper flange 51, the inner bottom part of drainpipe 5
Provided with lower flange 52, upper flange 51 and lower flange 52 are threadedly coupled with drainpipe 5 respectively, and the bottom surface of upper flange 51 is provided with ring packing
Ring 6, the top of lower flange 52 is provided with spring 8, and the top of spring 8 is connected with ball sealer 7, and ball sealer 7 offsets with annular sealing ring 6,
And the bottom surface of annular sealing ring 6 and the sphere of ball sealer 7 match, the inner bottom surface concave design of catch basin 4 is conducive to rainwater to flow into row
Water pipe 5, it is to avoid rainwater is resident in catch basin 4, and ball sealer 7 is engaged with annular sealing ring 6, it is ensured that sealing between the two
Property, while spring 8 only when rainwater gravity is more than its own resilient, can just shrink, enhancing ball sealer 7 and annular sealing ring 6 it
Between sealing.
Operation principle：Rainwater is flowed into catch basin 4 out of air duct body 1, when the gravity of water in catch basin 4 is more than spring 8
Elastic force when, spring 8 is shunk, and ball sealer 7 is separated with annular sealing ring 6, and water flows out from drainpipe 5, both ensure that air duct body 1
Sealing, while meeting drainage requirement again.
