Description
Technical field
The invention belongs to field of coal mine safety, it is related to mechanical sense and answers blast pressure waves every explosion suppression device.
Background technology
China is that one of country of gas and dust explosion accident most serious occurs in the world, and not only amount is more, and harm
Greatly, gas and dust explosion accident easily causes the dead group's wound of group, and mine is done great damage, made to the country and people's lives and properties
Into heavy losses, extensive negative effect is socially caused.In recent years, made joint efforts by each side, Safety of Coal Mine Production
Situation continually and steadily takes a turn for the better, and gas and dust explosion accident plays number and death toll declines year by year.But gas and dust explosion accident is total
Amount is still bigger than normal, and severe and great casualty happens occasionally, and the ratio for accounting for coal mining accident does not change substantially.With coal mining intensity and
The increase of depth, gas and coal dust safety in production threatens more acute, and working face absolute gas emission rate becomes big, dust-producing amount drastically increases
Plus, face bigger gas and dust explosion and threaten.
Every datonation-inhibition technology and it is equipped in the scale of control gas explosion accident there is obvious effect.It is active every datonation-inhibition
Device (electrical principles) because there are problems that reliability, still among further improve.Mechanical sense answers blast pressure
Waves are every explosion suppression device, using theory of mechanics, no electric part, can reliably suppress tunnel gas and dust explosion propagation.Do not produce
Raw energy consumption, maintaining is convenient, and economy is high, is easy to be installed on underground coal mine for a long time.The country is without correlation technique.Prior art is filled
The standby forward probe blast information by sensor, and control unit is transmitted, control unit triggers datonation-inhibition unit, sprayed out datonation-inhibition
Agent, suppresses or completely cuts off the propagation of gas and dust explosion.Prior art uses electrical principle, and energy consumption is big during day-to-day operation, reliability
Poor, the datonation-inhibition amount of single set storage is small, and cost is higher.
The content of the invention
In view of this, blast pressure waves are answered every explosion suppression device it is an object of the invention to provide a kind of mechanical sense.
To reach above-mentioned purpose, the present invention provides following technical scheme：
Mechanical sense answers blast pressure waves every explosion suppression device, including storage powder tank body, power injection device, blast pressure sensing
Device, the power injection device is provided with quick opening structure, and the storage powder tank body is provided with flow-guiding structure, the blast pressure
Power induction installation connects quick opening structure.
Further, the blast pressure induction installation includes catch bar and blast pressure inductive disks, the blast pressure sense
Connection catch bar should be coiled, the catch bar connects quick opening structure.
Further, the blast pressure inductive disks are two, are separated by and are arranged on catch bar.
Further, the power injection device is high-pressure chamber.
Further, the high-pressure chamber is provided with inflation inlet.
Further, the high-pressure chamber is provided with indicating pressure gauge.
Further, in addition to hanging port.
The beneficial effects of the present invention are：Mechanical sense answers blast pressure waves to be installed every explosion suppression device and is applied to coal mine
Under, device mechanically advanced detonation by influence shock wave, and shock wave is converted into thrust, when thrust is acted more than setting
During value, thrust can quickly promote fast opening mechanism to open storage pressure inert gas, and inert gas is promoted with good flow-guiding structure
Store datonation-inhibition pulvis tank body, rapid, high volume, it is remote spray out datonation-inhibition pulvis, completely cut off gas and dust explosion, control gas coal dust
Blast scale, reduces casualty loss.The present apparatus is without electric part, completely using theory of mechanics, and operating cost is low, reliability is high,
Explosion suppressant storage capacity is big, and jet length is remote, and the duration is long.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carried out
Explanation：
Fig. 1 is structural representation of the invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in figure 1, mechanical sense of the present invention answers blast pressure waves every explosion suppression device, including storage powder tank body 5, power injection
Device 7, blast pressure induction installation, the power injection device 7 are provided with quick opening structure 4, the storage powder tank body 5 and set
There is flow-guiding structure 6, the blast pressure induction installation connects quick opening structure.The blast pressure induction installation includes promoting
Bar 9 and blast pressure inductive disks 1, the blast pressure inductive disks 1 connect catch bar 9, and the catch bar 9 connects quick open and tied
Structure.The present embodiment blast pressure inductive disks are two, are separated by and are arranged on catch bar 9.One be arranged on catch bar 9 end,
Another is arranged on the afterbody of catch bar 9, and power injection device 7 is high-pressure chamber, and high-pressure chamber is provided with inflation inlet 8.It is described
High-pressure chamber is provided with indicating pressure gauge 3.Also include hanging port 2, hanging port 2 is arranged on catch bar 9 and storage powder tank body 5
On.
Powder tank body 5 is stored up built with datonation-inhibition pulvis, and provided with flow-guiding structure 6, rapidly can be sprayed datonation-inhibition pulvis during action
Out, the good datonation-inhibition barrier of injection is formed.Store up powder tank body and quick opening structure 4 is connected by screw thread and flange, it is quick to open
Structure 4 is threaded with high-pressure chamber, and indicating pressure gauge 3 and the thread forms of inflation inlet 8 are arranged on high-pressure chamber；Indicate pressure
