Abstract
The utility model relates to a downhole ventilation device, especially relates to a downhole anti-contrary wind device comprising a fan drum. An inner wall of the fan drum is provided with a flange, and a side wall of the flange is provided with a radial shaft. Two separation blades are disposed on two sides of the radial shaft, and are movably hinged to the radial shaft. A position-restricted device is disposed on the radial shaft between the two separation blades. By using the downhole anti-contrary wind device provided in the utility model, the contrary wind problem during the downhole ventilation can be solved. The downhole anti-contrary wind device has advantages of simple structure and convenient use.
Description
Technical field
The utility model relates to a kind of down-hole ventilation installation, relates in particular to a kind of down-hole regurgitation wind apparatus.
Background technology
People need constantly with under the air input well when underground work, and concentration of oxygen satisfies the needs of personnel to oxygen in the mine to increase, and get rid of gas assurance safety in production harmful in the mine.At first make the down-hole distinguished and admirable along the fixed route flow distribution, avoid distinguished and admirable reverse flow in the well on the other hand, toxic gas participates in the fresh air of input, life threatening safety.
Summary of the invention
The problem of air-flow reverse flow appears in the utility model when ventilating to the down-hole, a kind of regurgitation wind apparatus is provided, and makes the air-flow one-way flow, has solved problem against the wind.
For realizing above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of down-hole regurgitation wind apparatus, it comprises air duct, said air duct inwall is provided with flange; The flange sidewall is provided with radial axle, and said radial axle both sides are provided with two catch, and two catch all are movably hinged with radial axle; On the said radial axle stopping means is installed, between two catch.
As a kind of optimal way of the utility model, said stopping means is a T type structure, and the lower end is fixed on the radial axle, prevents that two catch are superimposed together.
As a kind of optimal way of the utility model, said air duct outer wall two ends are provided with collar, are used for fixing the ventilating duct that is connected the air duct end.
The utility model air duct inwall is provided with flange, and flange can be prevented that stop tab is reverse and opens, and is fixed with T type stopping means on the radial axle; Between two catch; Prevent that two catch are superimposed together, so as not to when occur against the wind can not with flangeseal together, solved and occurred problem against the wind when the down-hole ventilates; The utility model is simple in structure, and is easy to use.
Description of drawings
Fig. 1 the utility model structural representation.
The specific embodiment
As shown in Figure 1, be the utility model structural representation, a kind of down-hole regurgitation wind apparatus; It comprises air duct 1, and air duct 1 inwall is provided with flange 2, and flange 2 sidewalls are provided with radial axle 4; Said radial axle 4 both sides are provided with two catch, 3, two catch 3 and all are movably hinged with radial axle 4, and the stopping means 5 of T type structure is installed on the radial axle 4; Stopping means 5 lower ends are fixed on the radial axle 4, and the upper end is between two catch.Air duct 1 outer wall two ends are provided with collar 6.
When the utility model uses, the ventilating duct upper reaches are enclosed within the air duct left end, the ventilating duct downstream are enclosed within the air duct right-hand member, fix with collar, just can use work.
