Described pressure compensation aerating device is made up of 2 reducing valve and 3 pressure meters of being located on the high-pressure rubber pipe; It is that the nylon fabric of 1100D and the chlorosulfonated polyethylene adhesive plaster material that is added with the chlorosulfonated polyethylene raw material of antistatic additive are made that described air bag adopts intensity; Described limiting bracket is made of a plurality of stay pipes, a plurality of sleeve pipes that link to each other with stay pipe and the draw-tube that is located in the sleeve pipe, and the end of draw-tube is provided with the bulb supporting seat; Described sleeve pipe is provided with the concavity draw-in groove, is provided with the fixedly set bolt of draw-tube in the draw-in groove.
The automatic quick closing device in tunnel of the present utility model is applicable to that not having coal mine roadway electric, that nothing presses wind field to close during the catastrophe of colliery seals automatically fast.The pressure compensation aerating device is set between air bag and source of the gas, air bag is carried out automatic make-up air, the automation of realization gas replenishment process, unmanned, tonifying Qi automatically when the air bag release simultaneously; Limiting bracket height and width-adjustable, the outer end is provided with supporting seat, and is strong to the adaptive capacity of drift section, detachable, easy to carry; Fold formula structure is adopted on the air bag top layer, has improved the closed performance of air bag; , as high-pressure air source airbag aeration be need not electric power and presses wind with bottled gases at high pressure, safe and reliable, environmental suitability is strong; It is simple in structure, and is in light weight, be convenient to carrying and install, and need not to press wind, electric power, and safe and reliable, airtight tunnel is satisfactory for result, has practicality widely.
Description of drawings:
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is the lateral view of limiting bracket structure of the present utility model.
Among the figure: high-pressure air source 1, pressure compensation aerating device 2, air bag 3, limiting bracket 4, high-pressure rubber pipe 5, pressure meter 6, reducing valve; Stay pipe 4-1, sleeve pipe 4-2, draw-tube 4-3, draw-in groove 4-4, set bolt 4-5, supporting seat 4-6.
The specific embodiment
Below in conjunction with accompanying drawing an example of the present utility model is described further:
Shown in Figure 1, it is made of high-pressure air source 1, pressure compensation aerating device 2, air bag 3, limiting bracket 4, and gas enters air bag 3 by high-pressure air source 1 through pressure compensation aerating device 2 decompression, and air bag 3 is finished enclosing tunnel under limiting bracket 4 fixing.It is that the nylon fabric of 1100D and the chlorosulfonated polyethylene adhesive plaster material that is added with the chlorosulfonated polyethylene raw material of antistatic additive are made that air bag adopts intensity, and the chlorosulfonated polyethylene adhesive plaster is in light weight, and tensile strength is big, flexibility is good, airtight, fire-retardant, antistatic etc., and can bear certain high temperature.Pressure compensation aerating device 2 is made up of the reducing valve 7 and the pressure meter 6 that are located on the high-pressure rubber pipe 5, and pressure compensation aerating device 2 one ends link to each other with air bag 3 by the gas-charging connection 8 that is located on the high-pressure rubber pipe 5, and the other end connects high-pressure air source 1 by by-pass valve control.2 pairs of gases at high pressure of pressure compensation aerating device carry out second depressurized, but by regulating the gas pressure of reducing valve 7 setting pressure make-up air devices 2 outlets, when gas pressure in the air bag 3 reaches the exit gas pressure of pressure compensation aerating device 2 settings, gas replenishment process stops automatically, finishes the automatic inflation to air bag.If air bag release, be lower than the gas pressure of pressure compensation aerating device 2 gas outlets because of gas pressure in the air bag, then gas charges into air bag automatically, when the gas pressure of gas pressure in the air bag and pressure compensation aerating device 2 gas outlets reaches balance, the tonifying Qi process finishes, and promptly finishes automatic tonifying Qi process.Air bag 3 is provided with the inflation interface of make-up gas, and the inflation interface links to each other with gas-charging connection 8, and the top layer that air bag 3 contacts with the tunnel is a plicated layer, and its edge is the shirt rim, to improve seal.Shown in Figure 2, limiting bracket 4 is made up of a plurality of stay pipe 4-1, sleeve pipe 4-2 and draw-tube 4-3, between stay pipe 4-1 and the stay pipe 4-1, connect by screw thread between stay pipe 4-1 and the sleeve pipe 4-2, has realized the detachable, easy to carry of limiting bracket 4; By the draw-in groove 4-4 of sleeve pipe 4-2 and the set bolt 4-5 of draw-tube 4-3, sleeve pipe 4-2 and draw-tube 4-3 form a whole, and have realized the height and the width-adjustable of limiting bracket 4; The outer end of sleeve pipe 4-2 is provided with supporting seat 4-6, connects by ball-joint between sleeve pipe 4-2 and the supporting seat 4-6, and supporting seat 4-6 is freely rotated in the certain angle scope, has realized that the brute force in 4 pairs of tunnels of limiting bracket is fixed.4 pairs of drift section compliance of limiting bracket are strong, set up simple and direct, quick, firm, reliable to the fixed limit of air bag 3.High-pressure air source adopts bottled gases at high pressure, can finish and not have the tunnel sealing of pressing wind, no electric field to close, if there is the wind of pressure in sealing place, tunnel or annotates the nitrogen pipeline, also can adopt high pressure to press wind or nitrogen as high-pressure air source.
Its course of work: at first set up limiting bracket 4, air bag 3 is placed between the limiting bracket 4, connect high-pressure air source 1 and air bag 3 with high-pressure rubber pipe 5 then, open the valve of high-pressure air source 1, regulate pressure compensation aerating device 2, confirm that gas replenishment process begins, disaster relief personnel can withdraw the scene, disaster area immediately.
