Abstract
The utility model relates to a fast air-filling partition wall, which is composed of a piece of fire-proof cotton cloth (1), a sealant (2), an air bag (3), an air-filling hole (4), a viewing hole (5) and a fixing strap (6). The utility model is characterized in that air is filled into the air bag (3) through the air-filling hole (4) to force the air bag (3) to expand into a partition wall shape. The utility model uses the principle that the air bag (3) expands to block a tunnel, and with the advantages of simple, convenient and quick operation, the utility model can be widely used for temporary partition wall in an underground ventilation system; a pressure equalizing partition wall can be additionally arranged outside a partition wall in a closed fire region. The utility model is especially suitable for the closing, wind blocking and observation and close opening of underground fire area with gas explosion danger, and can quickly partition ventilation and oxygen supply, which creates precious time for emergency treatment to build a permanent partition wall.
Description
The utility model relates to the mine ventilation facility, and especially a kind of isolated roadway ventilates closes wall.
At present, it all is to be piled up by stone, loess to form that wall is closed in mine ventilation, closes wall temporarily and is made by plank etc.Because place, down-hole spatial constraints, building the movement process of removing, man-hour, material consumption are huge, and close wall and leak out seriously, topmost shortcoming is can not erect rapidly to close wall, can not guarantee at once that ventilation system is stable, can not provide rescue and relief for disasters and emergencies for mine and race against time.Belong to initiative both at home and abroad by domestic and international patent and normative document inspection " fast aeration is closed wall ".
The purpose of this utility model is the problem at above-mentioned existence, provide a kind of simple in structure, cost is low, can be repeatedly multiplexing, be convenient to the wall that closes that the down-hole uses.It can be made the inflation of respective shapes and close wall according to the different drift sections in down-hole, can play rapidly isolated roadway and ventilate.
Existing its structure of accompanying drawings:
Accompanying drawing 1 closes wall for the arch inflation
Accompanying drawing 2 closes wall for trapezoidal inflation
Accompanying drawing 3 closes wall for spherical inflation
Inflation is closed wall and is made up of fireproof asbestos cloth (1), sealing glue (2), air bag (3), air-filled pore (4), peep hole (5), fixed band (6) etc.
The formation of wall is closed in described inflation, and that its profile has is trapezoidal, arch, spherical three kinds, has peep hole (5), peep hole (5) to run through inflation at each positive middle part and closes the wall tow sides, be used for observing the variation of enclosed area, has below wall is closed in inflation and fills Pore (4), air-filled pore (4) are used for atmosphere is filled with in the air bag (3), and the periphery that closes the wall tow sides in inflation respectively is equipped with several fixed bands (6), and fixed band (6) is used for that wall is closed in inflation and the roadway perisporium is fixed.
In addition, leak out, also be furnished with the bar shaped air bag for preventing that inflation from closing between wall and the roadway perisporium.
Below describe inflation and close the wall use.Earlier inflation is closed wall fixed band (6) and hang firmly,, air bag (3) is expanded to inflate and closes wall and contact firm and solid with the roadway perisporium then fast to air-filled pore (4) inflation with the roadway perisporium.Can not contact firm and solid place, fill firm and solid getting final product with the bar shaped air bag.Need that wall is closed in inflation and remove when mobile, only need open air-filled pore (4) bleeds off gas, unties fixed band (6) and folds standby getting final product.
It is as follows that this fast aeration is closed the wall advantage:
1, the inflation front volume little, in light weight, the transportation, the keeping, easy to use.Inflation back tension greatly can be effectively completely real with the borehole wall, and leaking out between the wall closed in minimizing roadway wall and inflation.
2, construct that to close wall rapid, it is distinguished and admirable in time to block roadway, can be repeatedly used.
3, can close wall temporarily, forever close wall and use, outside Huo Qu closes wall, set up inflation and close wall, can effectively take fire fighting by equal pressure.
4, be specially adapted to the sealing that there is the dangerous fire of gas explosion district the down-hole, envelope etc. is scouted, risen to lock wind.Can set up and forever to close wall and win the quality time for combating a natural disaster the danger.
5, can alleviate staff's labour intensity effectively.Increase work efficiency.
Claims (4)
1, a kind of fast aeration is closed wall and is made up of fire prevention asbestos cloth (1), fluid sealant (2), air bag (3), air-filled pore (4), peep hole (5), fixed band (6) etc., it is characterized in that there is peep hole (5) at positive middle part, peep hole (5) closes the wall tow sides through inflation, close the positive basifacial of wall in inflation air-filled pore (4) is arranged, close the double-edged periphery of wall in inflation several fixed bands (6) respectively are housed, fixed band (6) is used for that wall is closed in inflation and the roadway perisporium is fixed.
2, fast aeration according to claim 1 is closed wall, it is characterized in that trapezoidal.
3, fast aeration according to claim 1 is closed wall, it is characterized in that arch.
4, fast aeration according to claim 1 is closed wall, it is characterized in that sphere.
