Description
Technical field
The present invention relates to technical field of mine safety more particularly to a kind of air duct anti-reverse-rotation devices for underground coal mine.
Background technology
Coal and gas prominent is the safety accident being susceptible in coal mine production, the high concentration watt that coal and gas prominent can be gushed out
This is met burning things which may cause a fire disaster and causes the disasters generation such as gas combustion and explosion, and in this case, high concentration gas outstanding passes through iron winds cylinder
Adverse current to it is fresh it is distinguished and admirable in, the fresh distinguished and admirable middle personnel's personal safety of crisis causes personnel's death by suffocation, it is, therefore, desirable to provide one
Kind novel air duct anti-reverse-rotation device for underground coal mine can be with for coal mine outburst prevention work face booster air duct
It prevents underground coal and gas burst accident from leading to the generation of inverted air current, can be impacted decrease fast after gas explosion disaster occurs
Intensity of wave, prevent wind current control, protect protrusion-dispelling wind outside it is fresh it is distinguished and admirable in personnel safety, ensure personal safety to greatest extent,
Prevent disaster diffusion from causing secondary disaster.
Invention content
Present invention solves the technical problem that：A kind of air duct anti-reverse-rotation device for underground coal mine is provided, for solving coal
When gas explosion accident occurring under mine, high concentration gas by iron winds cylinder adverse current to it is fresh it is distinguished and admirable in, crisis it is fresh it is distinguished and admirable in
Personnel's personal safety, the problem of causing personnel's death by suffocation.
Technical scheme of the present invention：
A kind of air duct anti-reverse-rotation device for underground coal mine, including iron winds cylinder, which further include supporting rod, two fans are semicircular prevents
Cover board, bar and shaft, the supporting rod is reversed to be vertically set in iron winds cylinder, described two fan anti-reverse cover boards are set respectively
It sets in supporting rod both sides and is hinged by shaft and supporting rod, bar setting is entered the wind in anti-reverse cover board close to iron winds cylinder
Mouth side.
It is additionally provided with nut in the shaft.
The supporting rod and bar is the round steel of diameter 12mm.
The nut is M14 type nuts.
Beneficial effects of the present invention：A kind of air duct anti-reverse-rotation device for underground coal mine is provided, when underground coal mine is normal
When ventilation, anti-reverse cover board automatic opening under portable blower wind pressure in iron winds cylinder, the normal air feed of iron winds cylinder, when freeing gas explosion thing
Therefore when, gas pressure outstanding is more than booster and generates wind pressure, and anti-reverse cover board is stood under the pressure effect of prominent gas
It closes, closing iron winds cylinder is to block the gas of adverse current, while anti-reverse cover board is blocked by bar, it is ensured that anti-reverse cover board
It will not overturn excessively, when gas explosion accident occurs for effective solution underground coal mine, high concentration gas passes through iron winds cylinder adverse current extremely
It is fresh it is distinguished and admirable in, the fresh distinguished and admirable middle personnel's personal safety of crisis, the problem of causing personnel's death by suffocation, ensures the person to greatest extent
Safety prevents disaster diffusion from causing secondary disaster.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is the enlarged diagram of a-quadrant in Fig. 1；
Fig. 3 is mounting structure schematic diagram of the present invention；
It is identified in figure：1, iron winds cylinder, 2, supporting rod, 3, anti-reverse cover board, 4, bar, 5, shaft, 6, nut.
Specific implementation mode
The present invention is described further below in conjunction with the accompanying drawings, a kind of air duct for underground coal mine of the present invention is anti-
Inversion set, including iron winds cylinder 1 further include that supporting rod 2, two fans semicircular anti-reverse cover board 3, bar 4 and shaft 5, described
Supporting rod 2 be vertically set in iron winds cylinder 1, described two fan anti-reverse cover boards 3 are separately positioned on 2 both sides of supporting rod and pass through
Shaft 5 is hinged with supporting rod 2, and the bar 4 is arranged in anti-reverse cover board 3 close to 1 air inlet side of iron winds cylinder.
It is additionally provided with nut 6 in the shaft 5, is used for fixed rotating shaft 5.
The supporting rod 2 and bar 4 is the round steel of diameter 12mm, has better mechanical strength, it is ensured that supporting rod 2
Anti-reverse cover board 3 can be effectively supported, meanwhile, bar 4 can block effect anti-reverse cover board 3, it is ensured that anti-reverse cover board 3 will not turn over
Degree of turning over.
The nut 6 is M14 type nuts.
As shown by dotted lines in figure 3 ranging from apparatus of the present invention installation position, be not prevented from crimp cause it is of the present invention
Failure of apparatus, forbid anti-reverse-rotation device being installed in protrusion-dispelling air door wall, and be mounted in the iron winds cylinder 1 after protrusion-dispelling air door
It is interior, while the present invention needs to inject capital into less, can voluntarily process to obtain.
The operation principle of the present invention：When underground coal mine is normally divulged information, anti-reverse cover board 3 is in portable blower wind pressure in iron winds cylinder 1
Lower automatic opening, 1 normal air feed of iron winds cylinder, when freeing gas explosion accident, gas pressure outstanding is more than booster
When generating wind pressure, anti-reverse cover board 3 is closed immediately under the pressure effect of prominent gas, and closing iron winds cylinder 1 is inverse to block
The gas of stream, while anti-reverse cover board 3 is blocked by bar 4, it is ensured that anti-reverse cover board 3 will not be overturn excessively, effective solution
When gas explosion accident occurs for underground coal mine, high concentration gas by iron winds cylinder adverse current to it is fresh it is distinguished and admirable in, crisis is fresh distinguished and admirable
Middle personnel's personal safety, ensures personal safety the problem of causing personnel's death by suffocation to greatest extent, prevents disaster diffusion from causing time
Raw disaster.
