Abstract
The utility model discloses a kind of counterflow-preventing automatic blocking air door window, and the window frame including being set to tunnel, window frame includes upper and lower two rectangular windows, and the top margin of each rectangular window is hinged with the luffer boards being adapted with window, and luffer boards constitute projecting top-hung window in rectangular window；Other three sides of each rectangular window are equipped with stopping dam, and stopping dam is located at tunnel contrary wind side；When blowing with the wind in tunnel, luffer boards are blown open, and wind realizes ventilation below luffer boards；When blowing contrary wind in tunnel, luffer boards are closed by self gravity, simultaneously because the effect of stopping dam, luffer boards will not reverse opening, to realize automatic blocking when contrary wind；Structure is simple, quick for installation, reliable operation.
Description
Technical field
The utility model relates to Air Throttle in Mine Pit technical field, specifically a kind of counterflow-preventing automatic blocking air door window.
Background technique
Rough estimates are reported according to national survey in 2010, and national coal and gas outburst mine quantity is 1044 within 2010
It is a, account for the 8.1% of national coal mine sum, proportion is at rising year by year trend.
In construction of coal mine, for the outburst dangerous area of mine, driving face inlet side must be provided at least twice road jail
Gu reliable reverse throttle.It is also distinctly claimed the 103rd article of " prevention and treatment coal and gas prominent regulation " and " passes through reverse throttle
Air duct, ditch, drag conveyor road of pier etc., it is necessary to be equipped with reverse partition apparatus." but original down hole reverse air door is logical
Since sensitivity is poor, the reasons such as installation maintenance is cumbersome are unfavorable for promoting the use of air regulator anti-backflow device.
Utility model content
The purpose of this utility model is to provide a kind of counterflow-preventing automatic blocking air door window, which can be in adverse current wind
When automatic blocking, structure is simple, quick for installation, reliable operation.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of counterflow-preventing automatic blocking air door window, the window frame including being set to tunnel, window frame include upper and lower two rectangular windows,
The top margin of each rectangular window is hinged with the luffer boards being adapted with rectangular window, and luffer boards constitute projecting top-hung window in rectangular window；
Other three sides of each rectangular window are equipped with stopping dam, and stopping dam is located at tunnel contrary wind side.
The utility model has the beneficial effects that luffer boards are blown open when blowing with the wind in tunnel, wind is below luffer boards around real
Now divulge information；When blowing contrary wind in tunnel, luffer boards are closed by self gravity, simultaneously because the effect of stopping dam, luffer boards will not be reversed
It opens, to realize automatic blocking when contrary wind；Structure is simple, quick for installation, reliable operation.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is state diagram when the utility model is blown with the wind in tunnel；
Fig. 3 is state diagram when the utility model blows contrary wind in tunnel.
Specific embodiment
In conjunction with shown in Fig. 1~3, the utility model provides a kind of counterflow-preventing automatic blocking air door window, including being set to tunnel
Window frame 1, window frame 1 include upper and lower two rectangular windows 2, and the top margin of each rectangular window 2 is all made of the hinged luffer boards 3 of hinge 5, luffer boards
3 are adapted with rectangular window, and luffer boards 3 constitute projecting top-hung window in rectangular window；Other three sides of each rectangular window are equipped with
Stopping dam 4, stopping dam 4 are located at tunnel contrary wind side.
When blowing with the wind in tunnel, luffer boards 3 are blown open, and wind realizes ventilation below luffer boards 3；When blown in tunnel against the wind
When, luffer boards 3 are closed by self gravity, simultaneously because the effect of stopping dam 4, luffer boards 3 will not reverse opening, thus when realizing contrary wind
Automatic blocking；Structure is simple, quick for installation, reliable operation.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation；Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment are still fallen within practical
In the range of the protection of new technique scheme.
