Description
Technical field
The invention belongs to the technical field of development machine, be specifically related to initiatively datonation-inhibition development machine of a kind of safety type.
Background technology
Gas is first killer who threatens safety of coal mines.The means of tradition control gas explosion are a kind of methods of passive control gas, mainly are by eliminating the condition (three factors: gas, burning things which may cause a fire disaster, oxygen) of gas explosion, taking extraction, ventilation to control gas and do not accumulate limiting concentration; Put an end to the fire source in the work.At present in the process of the blind lane of high-power machinery driving the instability of a large amount of gas gush out, all issuable spark of collision mutually between mechanical collision rock and machinery, caused mine safety hidden danger.At fully mechanized workface, except above-mentioned traditional method of preventing and treating, the spraying system of development machine self, its water smoke has played depositing dust, lowered the temperature and has dispersed the effect of gushing out gas.Yet, owing to reasons such as water source, equipment, this spraying system often result of use bad or sometimes since some factor affecting do not bring into play respective action.Like this, the spark that development machine pick and coal petrography collision produce will have huge potential safety hazard to mine.
Summary of the invention
There is very big omission in the present invention for the method that solves control gas explosion in the existing coal-mining technique, cutting head of roadheader pick and coal petrography collide the spark that produces in the fully-mechanized mining working in addition, to mine is the problem of huge potential safety hazard, and initiatively datonation-inhibition development machine of a kind of safety type is provided.
The present invention adopts following technical scheme:
Safety type is datonation-inhibition development machine initiatively, the cutting units front end that it is characterized in that development machine is equipped with explosion suppression device, some shower nozzles that described explosion suppression device comprises central processing unit, the monitoring device that is connected with central processing unit, store the high-pressure bottle of datonation-inhibition thing, be communicated with high-pressure bottle and controlled by central processing unit;
Described high-pressure bottle is L shaped structure, the embedded side that is installed on development machine;
Described shower nozzle is installed on cut reducer output shaft end, and is circular layout around cutting arm, and the Way out of each shower nozzle and cutting arm axis are angled ,-45 °≤angle≤45 °, has guaranteed that the datonation-inhibition material of ejection effectively forms datonation-inhibition barrier at the cutterhead place;
Monitoring device is installed on the both sides of shower nozzle, and is symmetrically arranged with respect to tunneling machine cutting arm center line, with shower nozzle on same plane.
Monitoring device is the spectral energy sensor.Central processing unit is arranged in by the driver's chair.
Beneficial effect of the present invention: utilize optical pickocff to monitor the spark of development machine pick and coal petrography collision generation in real time, central processing unit is analyzed, diagnosis, the little energy initial stage in blast is extinguished the combustion source, realize initiatively datonation-inhibition fast, prevent that it from developing into the gas and dust explosion accident, realize that active truly is datonation-inhibition, be used in combination with traditional flame proof, explosion precaution, can improve the ability that gas explosion accident is resisted in the colliery greatly, drop to the extent of injury of the condition of a disaster minimum.
Description of drawings
Fig. 1 is a structural representation of the present invention
Among the figure: 1-cutterhead, 2-monitoring device, 3-high-pressure bottle, 4-central processing unit.
The specific embodiment
Safety type is datonation-inhibition development machine initiatively, the cutting units front end of development machine is equipped with explosion suppression device, some shower nozzles that described explosion suppression device comprises central processing unit 4, the monitoring device 2 that is connected with central processing unit 4, store the high-pressure bottle 3 of datonation-inhibition thing, be communicated with high-pressure bottle 3 and controlled by central processing unit 4.
High-pressure bottle 3 is " L " shape structure, embeds the development machine side during installation, and for well, the volume of high-pressure bottle can be guaranteed like this at tunneling machine cutting motor side cut hoist cylinder pin joint place in the position, and the while does not influence the technical data of development machine again.
During development machine work, be easy to generate spark when cutterhead and coal petrography collision, form potential safety hazard, explosion suppression device is installed on tunneling machine cutting portion, shower nozzle and high-pressure bottle spacing and dwindles as far as possible, more effectively brings into play its effect.And explosion suppression device is when being installed on the cutting units front end, because the compact conformation of development machine own, the structure of high-pressure bottle must be subjected to the restriction of technical datas such as tunneling machine cutting height, width, and nozzle layout of sprinkler is also overlapped with water spray external spraying device.Selected shower nozzle is spherical porous form, and in order to utilize the space better, with the reach of water spray external spraying device, appearance integral dwindles under the prerequisite that does not influence spray effect.Initiatively datonation-inhibition shower nozzle is installed on cut reducer output shaft end, it also is former water spraying device place, be circular layout around cutting arm, the Way out of each shower nozzle and cutting arm axis are angled,-45 °≤angle≤45 °,, when guaranteeing its work, the datonation-inhibition thing that all shower nozzles sprayed can form the face of a complete covering cut scope, reaches initiatively datonation-inhibition purpose.
Monitoring device has been installed at position suitable on the development machine of the present invention, and monitoring device is arranged in the both sides of shower nozzle, and is symmetrically arranged with respect to tunneling machine cutting arm center line, with shower nozzle on same plane.Monitoring range covers whole cutterhead effectively, can monitor signal acquisition quickly and accurately in real time, and feed back to central processing unit, after central processing unit is analyzed, is diagnosed signal, send instruction with fire-retardant medium injection in the high-pressure bottle to target zone, form barrier, blocking-up gas explosion is propagated and is enlarged.Monitoring device, accurately sensitive, adopted the spectral energy sensor, by luminous energy, heat energy signal acquisition.Provide 5～127V power supply to the active explosion suppression device by development machine machine electric control box, this installs detectable 5m 1 candle light flame in addition, and total score is separated out useful signal, and the output high-voltage pulse signal is given central processing unit.Central processing unit is integrated in the operating mechanism place of development machine, is arranged in by the driver's chair, and the high-voltage pulse signal that monitoring device is sent carries out the rapid analysis diagnosis, judges that signal effectively sends instruction.The high pressure fire-retarding device, solid flame retardant is stored in the high-pressure bottle.Receive effective instruction, discharge fire-retardant datonation-inhibition medium fast, form datonation-inhibition barrier, the personnel's safety of life and property behind the datonation-inhibition barrier is effectively protected in the diffusion of blocking-up blast.This system monitors in 5ms and definite detonator signal, forms the fire retardant dust cloud in the 50ms, and the dust cloud RT is 1s.Can effectively cover the whole cutterhead of development machine.
