Abstract
The utility model discloses an electromagnetic type anti-explosion opening device. The device comprises a pressure container, a generator, an electromagnet, a valve piston, a limit mechanism and a shock wave sensor; the limit mechanism and the valve piston are arranged on an opening channel of the pressure container; the shock wave sensor is arranged on the generator; the generator is electrically connected with the electromagnet; the electromagnet is connected with the valve piston; and the pressure container contains high-pressure gas and fire extinguishing materials. When gas or coal dust burns or explodes, precursor shock waves in the explosion are used as kinetic energy to drive the device to quickly open a valve of the pressure container, the fire extinguishing materials are allowed to form a frog-shaped isolation strip in an alley in short time in a larger spraying range, and explosion fire of the gas and the coal dust is limited near an explosion source, so people and materials can be timely and quickly protected.
Description
Technical field
The utility model belongs to gas flame proof quick opening field, specifically a kind of electromagnetic type flame proof opening device.
Background technology
At present, coal mine flame-proof device is selected passive type explosion isolation camp mostly, isolated blast water bottle, flame proof groove etc. carries out flame proof, but in 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 explosion isolation camp district, forerunner's blast wave that blast produces is thrown and is held the plank of rock dust or make tank, water bag is broken, inert dust or the water smoke of the state of flying upward is filled the air in formation, in tunnel, form the inhibition zone of stamping out the flames, 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 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
0time, 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, flame proof material forms that the time of flame proof effect is shorter, and 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 electromagnetic type flame proof opening device, when blasting, can trigger rapidly, isolated burning things which may cause a fire disaster, as early as possible fire extinguishing.
The technical scheme that the utility model provides is: a kind of electromagnetic type flame proof opening device, it is characterized in that: comprise pressure vessel, generator, electromagnet, valve piston, position-limit mechanism and shock wave transducer, the open channel of pressure vessel is provided with position-limit mechanism and valve piston, shock wave transducer is arranged on generator, generator is electrically connected to electromagnet, and electromagnet is connected with valve piston again.
Gases at high pressure and extinguish material are housed in described pressure vessel.
The beneficial effects of the utility model are: when there is gas or coal dust generation combustion explosion; the utility model take blast forerunner shock wave be kinetic energy; drive the utility model; make it open fast the valve of pressure vessel; make in the extinguish material within a short period of time of sprinkling in a big way; in tunnel, form vaporific isolation strip, gas and dust explosion flame is limited near quick-fried source, play in time, protect fast the effect of personnel and material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, shock wave transducer, 2, generator, 3, electromagnet, 4, valve piston, 5, pressure vessel, 6, position-limit mechanism.
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 electromagnetic type flame proof opening device, comprise pressure vessel, generator, electromagnet, valve piston, position-limit mechanism and shock wave transducer, the open channel of pressure vessel is provided with position-limit mechanism and valve piston, shock wave transducer is arranged on generator, generator is electrically connected to electromagnet, and electromagnet is connected with valve piston again.Gases at high pressure and extinguish material are wherein housed in pressure vessel.
While not blasting, be subject to the restriction of position-limit mechanism, valve piston makes pressure vessel in sealing state, stops the material ejection of pressure vessel inside; While blasting, shock wave transducer receives shock wave pressure, make generator work generating, thereby make work of electromagnet, drive valve piston motion, make valve piston displacement, get through pressure vessel to the passage of spout, pressure vessel mesohigh gas carries extinguish material instantaneous (approximately more than 20 millisecond) ejection, in the scope of spout direction 30m left and right, forms atomization isolation strip, gas and dust explosion flame is limited near quick-fried source, thus isolated burning things which may cause a fire disaster.
