Abstract
The utility model discloses an air pressing type explosive-proof opening device which comprises a pressure chamber. A nozzle is formed in one end of the pressure chamber, and a sealing film is arranged at the passageway of the nozzle of the pressure chamber in a sealing mode. A pressure piston is arranged at the other end of the pressure chamber, the periphery of the pressure piston is in close contact with the inner wall of the pressure chamber, the pressure piston is connected with a piston rod through a pressure spring, and the other end of the piston rod stretches out of the pressure chamber. A starting locking block is further arranged on the piston rod, the starting locking block clamps the piston rod to enable the pressure spring to be in a compression state, a trigger is arranged on the starting locking block, and high-pressure gas and extinguishment materials are contained in the pressure chamber. When an explosion occurs, explosion prodromic shock waves are used as kinetic energy of the device, the device is driven to fast open the sealing film of the pressure chamber, the extinguishment materials are sprayed in a large range within a short time, a fog-shaped isolation belt is formed in a roadway, gas and dust explosion flames are limited close to an explosion source, and the function of protecting personnel and materials fast and timely is achieved.
Description
Technical field
The utility model belongs to gas flame proof quick opening field, specifically a kind of air pressing type flame proof opening device.
Background technology
At present, the coal mine flame-proof device is selected the passive type explosion isolation camp mostly, isolated blast water bottle, flame proof groove etc. carries out flame proof, but in the passive type explosion isolation device, the spraying of its triggering and blast reducer is all by gas, forerunner's blast wave that coal-dust explosion produces completes, when gas occurs, during coal-dust explosion, before explosive flame arrives the explosion isolation camp district, forerunner's blast wave that blast produces is thrown and is held the plank of rock dust or make tank, the water bag fragmentation, inert dust or the water smoke of the state of flying upward is filled the air in formation, form the inhibition zone of stamping out the flames in tunnel, play heat absorption, cooling, fire-retardant effect, gas and dust explosion flame is limited near quick-fried source.
But because the flame proof condition of explosion isolation camp can be expressed as:
P≥P
0；
t
d＜﹙T
P-T
f﹚＜t
d+t
s。
In formula: P-forerunner's blast pressure; P
0-explosion isolation camp moves required pressure; t
d-explosion isolation camp moves the required time; t
sthe duration of-water smoke or rock dust; T
p-forerunner blast wave arrives the moment of explosion isolation camp; T
f-explosive flame arrives the moment of explosion isolation camp.
When explosive morphology is smaller, forerunner's blast pressure P<P
0the time, explosion isolation camp can not obtain enough kinetic energy and be thrown and lost efficacy, and flame will spread immediately, causes N time larger blast, has strengthened the casualty loss of personnel and property.Moreover even if explosion isolation camp obtained enough kinetic energy and thrown, the flame proof material forms that the time of flame proof effect is shorter, and the flame proof narrow range, can not play effectiveness completely, once allow flame break through isolation strip, will continue to spread, and causes great personnel's property loss.
Summary of the invention
The purpose of this utility model is to provide a kind of air pressing type flame proof opening device, when blasting, can trigger rapidly, isolated burning things which may cause a fire disaster, fire extinguishing as early as possible.
The technical scheme that the utility model provides is: a kind of air pressing type flame proof opening device is characterized in that: comprise balancing gate pit, an end of described balancing gate pit is provided with spout, and the spout passage place sealing of balancing gate pit arranges diaphragm seal; The other end of balancing gate pit is equipped with pressure piston, the inwall close contact of the surrounding of pressure piston and balancing gate pit, and pressure piston connects piston rod by compression spring, and the other end of piston rod stretches out outside balancing gate pit; Also be provided with the startup lock dog on piston rod, start lock dog seized piston bar and make compression spring in compressive state, start on lock dog trigger is housed.
Gases at high pressure and extinguish material are housed in described balancing gate pit.
The beneficial effects of the utility model are: when gas or coal dust generation combustion explosion occur; the utility model take the blast forerunner shock wave be kinetic energy; drive the utility model; make it open fast the diaphragm seal of balancing gate pit; make in the extinguish material within a short period of time of sprinkling in a big way; form vaporific isolation strip in tunnel, gas and dust explosion flame is limited near quick-fried source, play in time, protect fast the effect of personnel and material.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, balancing gate pit, 2, spout, 3, diaphragm seal, 4, pressure piston, 5, compression spring, 6, piston rod, 7, start lock dog, 8, trigger.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the utility model is not limited to this.
As shown in Figure 1, a kind of air pressing type flame proof opening device, comprise balancing gate pit, and an end of balancing gate pit is provided with spout, and the spout passage place sealing of balancing gate pit arranges diaphragm seal; The other end of balancing gate pit is equipped with pressure piston, the inwall close contact of the surrounding of pressure piston and balancing gate pit, and pressure piston connects piston rod by compression spring, and the other end of piston rod stretches out outside balancing gate pit; Also be provided with the startup lock dog on piston rod, start lock dog seized piston bar and make compression spring in compressive state, start on lock dog trigger is housed.Wherein, gases at high pressure and extinguish material are housed in balancing gate pit.
While not blasting, start lock dog seized piston bar and make compression spring in compressive state, balancing gate pit is in sealing state, and inner material can't spray; While blasting, when shock wave pressure arrives trigger, trigger affects the startup lock dog, open the lock-bit of piston rod, pressure piston outwards moves under the effect of compression spring, the pressure piston of compression spring drive simultaneously moves to the spout direction, diaphragm seal breaks under pressure, balancing gate pit's mesohigh gas carries extinguish material instantaneous (approximately more than 20 millisecond) ejection, form the atomization isolation strip in the scope of spout direction 30m left and right, gas and dust explosion flame is limited near quick-fried source, thus isolated burning things which may cause a fire disaster.
