Abstract

The invention discloses full-automatic safety equipment of a driving-face well roadway with personnel positioning, which is arranged in the range of 6m towards the inside from an air-return roadway opening of the driving-face well roadway and is used for preventing accidents such as fire, flood, coal and gas outburst and the like on a driving face. The full-automatic safety equipment is characterized in that heavy type supports and the four walls of the well roadway are firmly fixed into a whole; a steel heavy type channel device is arranged among the heavy type supports at the four walls of the roadway and is controlled by a motor which is controlled by a liquid level sensor; and when the flood accident occurs on the driving face, the water level of the flood acts on the liquid level sensor, and the liquid level sensor controls the motor which closes the steel heavy type channel device quickly.

Description

A kind of driving face roadway automatic safety equipment that personnel positioning is housed

Technical field: a kind of driving face roadway automatic safety equipment that personnel positioning is housed belongs to a kind of safety equipment of installing in the underworkings of colliery, is specially adapted under the coal mine each access adit and installs and uses.

Background technology: through prevent the equipment of various natural calamities a lot of under the retrieval coal mine both at home and abroad comprehensively; But can be used in the outstanding equipment of Automatic Control fire, floods, coal and gas, all do not find both at home and abroad, the down-hole catches fire and mainly uses the fire dam fire sealing at present; It also mainly is shutoff that floods take place; And take place coal with gas when outstanding the measure means a lot, but also exist and can't fire expansion often occur with disaster control within the specific limits; Floods flood whole mine, and gas is outstanding to cause that significant explosion causes well to ruin serious accidents such as the people dies.

Summary of the invention: the objective of the invention is the problem to above-mentioned existence, through domestic and international visiting and learning and three more than ten years the coal mining accident management experience and test of many times invented this technology.

A kind of driving face roadway automatic safety equipment that personnel positioning is housed, the return airway road junction that is installed in the driving face tunnel be inward in 6 meters the scope, accident such as gives prominence in order to prevention driving face fire, floods, coal and gas; It is characterized in that: be one by fixedly securing between heavy supporting and the roadway wall; The steel heavy lane device is installed between the heavy supporting of roadway wall, and the steel heavy lane device receives Electric Machine Control, and motor is controlled by liquid level sensor; When driving face generation floods accident; The floods water level affacts on the liquid level sensor, and liquid level sensor control motor cuts out the steel heavy lane device rapidly by motor.

Top at heavy lane device mouth is equipped with personnel location system; On the top of heavy lane device mouth,, be fixed on the frame of heavy lane device the form of personnel location system through buckling; All in advance passed through heavy lane device with interior as if the personnel in the work plane at 5 minutes; Then heavy lane device can be closed in advance, if under the situation that high temperature, high concentration gas and gushing water water level transfinite, heavy lane device can and be closed later at 5 minutes automatically; To reduce accident scope that involves and the time that reduces accident impact, the personnel that can't come out come out through the escape hatch on the heavy lane device.

Shower nozzle on the prevention and control coal dust gas explosion accident equipment is installed on the frame on heavy lane device top; Be fastenedly connected through screw; Shower nozzle points to driving face, and shower nozzle is directly opened shower nozzle through the signal of probe output, and sprays fire-fighting, fire extinguishing, cooling, depositing dust, flame proof liquid; Shower nozzle all is connected by the screw flange with electromagnetic valve and pipeline that control is opened; Be separately installed with the shower nozzle on the prevention and control coal dust gas explosion accident equipment at the front end of heavy lane device, when the probe gas density surpasses 30%, after the tunnel temperature surpasses 200 ℃; The output signal can automatically be opened the shower nozzle on the prevention and control coal dust gas explosion accident equipment on the probe, controls immediately and dilutes gas density and put out the high temperature burning things which may cause a fire disaster and eliminate coal-dust explosion.

A kind of driving face roadway automatic safety equipment that personnel positioning is housed all adopts the power supply of dual power supply and batteries; When the down-hole since accidental cause have a power failure; The batteries power supply is from a kind of driving face roadway automatic safety equipment power supply that personnel positioning is housed of trend; When the down-hole restores electricity, the automatic disconnection of batteries power supply.

A kind of driving face roadway automatic safety equipment that personnel positioning is housed compared with prior art has the following advantages:

1, a kind of driving face roadway automatic safety equipment that personnel positioning is housed adopts the resistance to compression of high strength heavy type steel, antiknock, firm.

2, adopt combined type easy for installation, quick, can be with the moving of driving face, and can be repeatedly used.

3, can various accidents be controlled at the roadway mouth with the lining, avoid accident to enlarge and injure other place, down-hole.

4, be easy in time control the generation of various accidents, because hanging in advance of each sensor provides grace time for closing heavy lane device.

5, realized " one through three prevention, the comprehensive regulation ", not only can ventilate, combat a natural disaster, take precautions against natural calamities, and realized the mine essential safe type.

6, the various sensors on a kind of driving face roadway automatic safety equipment that personnel positioning is housed can with underground monitoring monitoring networking, and be transferred to ground and carry out Artificial Control and open.

7, a kind of driving face roadway automatic safety equipment that personnel positioning is housed has simple in structurely, and overall dimension is compact, and fault is few, and self-security is high, and can take precautions against natural calamities, can combat a natural disaster, but the also disaster relief.
