Description
Technical field
It the utility model is related 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, realize exchange fresh distinguished and admirable and that pollution is distinguished and admirable.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 underground chamber temperature, the damp-heat air in 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 worker 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.
Utility model content
The purpose of this utility model is easily sustained damage in drainage procedure to solve to exist in the prior art air duct
The shortcomings that, and a kind of mining ventilating tunnel drainage arrangement proposed.
To achieve these goals, the utility model 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, institute
State air duct body outer bottom and be provided with shed, the upper shed is connected with shed, and porous plate, institute are provided with the under shed
To state multi-well plate bottom and be provided with catch basin, the reservoir bases are communicated with drainpipe, and the drainpipe inner top is provided with upper flange,
The drainpipe inner bottom part is provided with lower flange, and the upper flange bottom surface is provided with annular sealing ring, is provided with the top of the lower flange
Spring, the spring top are connected with ball sealer, and the ball sealer offsets with annular sealing ring, and annular sealing ring bottom surface with it is close
The sphere of blocking matches.
Preferably, the cross-sectional area of the under shed is more than the cross-sectional area of upper shed.
Preferably, 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.
Preferably, the catch basin inner bottom surface is to lower recess, and lowest part connects with drainpipe top in catch basin.
Preferably, the upper flange and lower flange are threadedly coupled with drainpipe respectively.
The utility model proposes a kind of mining ventilating tunnel drainage arrangement, beneficial effect is：The apparatus structure is simple, uses
Convenient, effectively by rainwater-collecting in catch basin, when the water in catch basin reaches constant weight, pressuring spring shrinks, and makes
Obtain ball sealer to separate with annular sealing ring, the rainwater in catch basin flows out out of drainpipe, has not only reached the effect of sealing, together
When can also meet dewatering needs, do not damage air duct self structure.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of mining ventilating tunnel drainage arrangement structural representation；
Fig. 2 be the utility model proposes a kind of catch basin of mining ventilating tunnel drainage arrangement and the cross-section structure of drainpipe show
It is intended to.
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 utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
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 connects 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 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 connects 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 are 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 advantageous to rainwater and flows into row
Water pipe 5, rainwater is avoided to be resident in catch basin 4, ball sealer 7 is engaged with annular sealing ring 6, ensures sealing between the two
Property, while spring 8 can just shrink only when rainwater gravity is more than its own resilient, enhancing ball sealer 7 and annular sealing ring 6 it
Between sealing.
