Description
Technical field
The present invention relates to a kind of safety helmet type individual escaping device for gas explosion under coal mine.
Background technology
Because rapid development of economy also is raising at full speed to demands for energy, as being the country of primary raw material with coal, the yield of coal also climbs up and up, so mine safety accidents also causes a tremendous loss of lives again and again.Through the mass data analysis of and casualty on-the-spot, find that the death toll of underground work causes because sucked CO gas after the gas explosion more than 90% to mine disaster.
Lifesaving booth is all arranged under some large-scale mines; As long as gas explosion accident generation front and back personnel in the pit can get into survival capsule smoothly and just can not be in peril of one's life; But accident will take place in the short time at the utmost point when meeting the outstanding situation of gas, if adopt traditional self-rescuer to have no idea to save oneself at short notice at all.
For a long time, the isolation type oxygen self-rescuer service routine generally used of down-hole, mine is comparatively loaded down with trivial details.Usually unload the respirator of wearing earlier, open two bayonet sockets of breather loam cake, take off loam cake, opening valve gate open oxygen is clamped the nose clip on the leather bag with nose, opens the air bag stopper and catches in its mouth leather bag breathing mouth then.Under the skilled situation of calmness, needed for 90 seconds from receiving the gas early warning at least to beginning to wear the chemical oxidation self-rescuer, at this moment the underground labour also must stop operation, has so also taken valuable escape time.Add the traditional chemical oxygen self-rescuer and must be hand-held or mouth is stung also and made troubles to escape; In case more likely cause its stupor if the shock wave of its generation of gas explosion is very likely fallen down the underground work personnel; At this moment oxygen self-rescuer will break away from the effect that does not reach protection from mouth and nose, finally will be choked to death by carbon monoxide.
We see that from a large amount of fire damp explosion scene data the concentration of its carbon monoxide of fire damp blast back is generally 1～10%, and these data mean, under this environment, will lose valuable life as long as suck flatly.We can judge that conventional self-rescue apparatus saving oneself in the fire damp blast process almost cannot so.
Also have some products to adopt firedamp sensor, carbon monoxide transducer, pressure sensor or shock sensor in the hope of reaching the effect of " automatically " now, but these products finally just rest on the paper.Its impracticable reason mainly is:
If 1, firedamp sensor, carbon monoxide transducer are worn to and necessarily require volume little, in light weight on the individuality.But the product response time of these " mini " types reaches 1～2 minute, and sensitivity is differential.
2, the higher imported product of sensitivity its cost an arm and a leg more than thousand yuan, obviously not have the meaning of popularization as the accessory of individuality equipment with such product.
3 pressure, shock sensor also can cause its misoperation because of reasons such as the influence of the vibrations in the course of work, site plant and junks; Can imagine how such workman can feel at ease to produce, and how long each misoperation to repair to its injury that causes psychologically.
Summary of the invention
The objective of the invention is to above-mentioned present situation, aim to provide a kind of need not the ventilation by artificial Open valve, combine firmly with the user, for the underground work personnel provide the quality time of escape and the safety helmet type individual escaping device for gas explosion under coal mine of chance.
The implementation of the object of the invention does, safety helmet type individual escaping device for gas explosion under coal mine is made up of automatic oxygen breathing apparatus, safety helmet and control section,
Automatically the housing bottom of oxygen breathing apparatus is adorned oxygen cylinder on one side; Oxygen bottle, strainer, reducing valve, pressure meter and electromagnetic valve screw thread are chained together; Electromagnetic valve, overflow valve are connected with leather bag, and the exhalation vents of gas conduit is connected with outgassing nonreturn valve, and place leather bag; The air entry of gas conduit is connected with breather check valve, outgassing nonreturn valve and CO
2Central hollow tube in the absorbent connects, and power supply and control circuit board are put into the housing bottom under the oxygen cylinder, and housing bottom another side dress screen cloth has CO in the screen cloth
2Absorbent, leather bag are folded in the loam cake, and loam cake is connected with housing, the housing bottom sealing,
Between the cap body of safety helmet and the hat lining ventilating pipe is arranged; Ventilating pipe one end is communicated with steam hose, and the other end is communicated with through the efferent duct of the electromagnetic valve on interface A and the oxygen tank, the steam hose other end and contact the face shield connection of face; The face shield of contact face is connected with elastic cord with hat lining
The positive pole of power supply connects 1 pin of circuit of three-terminal voltage-stabilizing integrated N1; Negative pole connects 2 pin of circuit of three-terminal voltage-stabilizing integrated N1; 3 pin of circuit of three-terminal voltage-stabilizing integrated N1 connect 1 pin of superregenerative reception device N2; 2 pin of superregenerative reception device N2 connect 1 pin of decoder element N3, and 4 pin of decoder element N3 connect 1 pin of the one or six inverter trigger N4, and 2 pin of the one or six inverter trigger N4 connect 3 pin of the two or six inverter trigger N5; 4 pin of the two or six inverter trigger N5 are connected with the input of triode FET Q1, the output termination electromagnetic valve DC1 of triode FET Q1 and the input B of light emitting diode or buzzer.
The present invention receives the early warning signal that early warning net transmits through the superregenerative reception device, and through decoding, being amplified to triode FET Q1, triode FET Q1 passes to electromagnetic valve and buzzer with early warning signal; Electromagnetic valve is opened; Oxygen in the oxygen bottle filters through strainer, and the reducing valve step-down becomes oxygenation in leather bag behind 10 kilograms of pressure, is folded in leather bag in the loam cake under the promotion of 10 kilograms of pressure; After movable loam cake backed down; Break away from and open fully, and through gas conduit to the face shield oxygen supply that is hidden in the contact face in the cap body, the gas of exhalation is through gas conduit, the outgassing nonreturn valve CO that flows through
2Absorbent recycles after cleaning, filtering.After the wearer heard the warning of buzzer, leaving behind was hidden in the face shield of the contact face in the cap body, covers mouth and nose and gets final product.
The present invention has following advantage:
1, utilizes existing safety monitoring system in colliery and early warning net
2, compressed oxygen is imported leather bag automatically through explosion-proof solenoid valve, need not ventilate by artificial Open valve,
3, through 10 kilograms of oxygen pressures leather bag is backed down the breather loam cake, leather bag ejects automatically and has reduced the manually-operated time of uncap,
4, the use of the face shield of concealed contact face has been saved a large amount of manually-operated links and has effectively been prevented because the breather that explosion wave causes comes off, leaks gas and quits work,
The present invention has solved traditional self-help apparatus fully and has worn loaded down with trivial detailsly, when receiving the blast impulse wave action, breaks away from human body easily and go into a coma and individually cause the corners of the mouth to leak gas because of losing consciousness or body pressure problem such as cause that breather quits work inadequately.In the nervous scene of the accident of acting hurriedly in a messy situation; Use the present invention; Need not the user of service spend a large amount of valuable time manually opened, wear breather, for the underground work personnel provide the quality time and the chance of escape, the staff who waits for rescue for stranded down-hole provides existence to ensure.
