Description
Technical field
The utility model relates to a kind of down-hole air interchanger, especially a kind of compound protrusion-dispelling air door regulation wind window device.
Background technology
It is ensure personal security and produce one of normal the most basic condition that underground coal mine ventilates.Regulation wind window is used for distributing air quantity in wind net, ensures the air quantity demand in each main wind place, in mine ventilation facility, is in critical role.Regulation wind window, by changing the cross-sectional sizes of ventilation window, realizes the adjustment of ventilation.At present, most of mine protrusion-dispelling air door is all installed on regulation wind window device, but due to the structure restriction of regulation wind window conventional at present, a lot of inconvenience is all there is in regulation wind window on the high-order small space of underground coal mine is installed and used, majority all cannot facilitate calculating to appear wind area, cannot provide calculating data for regulating tunnel air quantity.And general regulation wind window apparatus structure is complicated, sensitivity is low, install and process all very inconvenient, processing installation is wasted time and energy, and majority does not possess protrusion-dispelling effect, there is potential safety hazard, need to research and develop novel protrusion-dispelling air door regulation wind window device, to meet mine safety High-efficient Production needs.
Summary of the invention
According to the deficiency that prior art exists, provide a kind of structure simple, install easy to process, there is protrusion-dispelling performance, safe and reliable compound protrusion-dispelling air door regulation wind window device.
The purpose of this utility model realizes in the following manner: a kind of compound protrusion-dispelling air door regulation wind window device, comprise quadra, the side of described quadra is provided with guide rail, guide rail side is provided with the spacing framework of blade, verge board is movably installed with in guide rail, be vertically arranged with fixed axis in the spacing frame mid portion of blade, be set with two pieces of blades outside fixed axis, fixed axis is installed with blade link stopper.
Described verge board is two pieces, and verge board is provided with push and pull bar, and described guide rail is two, and guide rail is fixedly mounted on the two ends up and down of quadra side, between verge board is movably arranged on inside two orbit of guide rail.
The quadra of described verge board bottom is provided with sized signage.
Described quadra and the spacing framework of blade are welded by four angle bar respectively.
Described blade link stopper is in " T " character form structure, and the longitudinal component being somebody's turn to do " T " character form structure blade link stopper is connected with fixed axis is vertical, and lateral part is upper parallel below with quadra.
The width sum of two pieces of described blades is not less than the width of the spacing framework of blade.
Relative to prior art, the utility model installs rotating fan blade additional in the middle part of regulation wind window, solve original regulation wind window and do not have a low problem of protrusion-dispelling, safety, and make processing easier for installation, simple to operate, reliably sensitive, can calculated wind area easily by sized signage, provide calculating data for regulating tunnel air quantity.

Detailed description of the invention
A kind of compound protrusion-dispelling air door regulation wind window device as shown in Figure 1, a kind of compound protrusion-dispelling air door regulation wind window device, comprise quadra 1, the side of described quadra 1 is provided with guide rail 2, guide rail 2 side is provided with the spacing framework 4 of blade, is movably installed with verge board 3 in guide rail 2, in the middle part of the spacing framework 4 of blade, be vertically arranged with fixed axis 5, be set with two pieces of blades 6 outside fixed axis 5, fixed axis 5 is installed with blade link stopper 7.
Described verge board 3 is two pieces, and verge board 3 is provided with push and pull bar 8, and described guide rail 2 is two, and guide rail 2 is fixedly mounted on the two ends up and down of quadra 1 side, between verge board 3 is movably arranged on inside two guide rail 2 tracks.The quadra 1 of described verge board 3 bottom is provided with sized signage 13.Described quadra 1 and the spacing framework 4 of blade are welded by four angle bar respectively.Described blade link stopper 7, in " T " character form structure, should the longitudinal component of " T " character form structure blade link stopper 7 be connected with fixed axis 5 is vertical, lateral part and quadra) upper parallel below.The width sum of two pieces of described blades 6 is not less than the width of the spacing framework 4 of blade.For firmly easy for installation, vertical fixed installation fixed bar 14 on the spacing framework 4 of blade.
This product is generally arranged on air door body of wall middle and upper part, directly over air door, one and the sizable wall hole of the spacing framework of blade 4 need be set when mounted on air door body of wall, the partial fixing of fixed bar 14 and quadra 1 is installed on protrusion-dispelling air door body of wall inside, within the spacing framework 4 of blade, part and verge board 3 are located in wall hole, during normal use, by verge board 3 any adjusted wind area in prescribed limit, and directly read wind area by the sizing board 13 that the quadra 1 below it is arranged, when mine generation coal and gas prominent or explosion time, powerful air-flow or the short two pieces of blades 6 of shock wave rotate, as shown in Figure 4, two pieces of blade 6 Automatic-expandings, when turning to the position of the spacing framework 4 of blade, blade 6 is blocked by the spacing framework 4 of blade and cannot continue to rotation, thus block distinguished and admirable, and then stop that tunnel high concentration gas air-flow and toxic and harmful enter protrusion-dispelling air door opposite side by regulation wind window, prevent the expansion of the scope of being injured in time, further lifting mine anti-disaster ability, be conducive to mine safety production.Blade link stopper 7 is between two pieces of blades 6 and can prevents two pieces of blades 6 from folding, and during rotation, deflection is same.
