Abstract

A full-automatic safety device of a stope working face roadway is installed at an air inlet and return roadway entrance of a stope working face, used for preventing and controlling 'one ventilation and three prevention' accidents of the stope working face and characterized in that heavy-duty supports and the shaft wall are fixed firmly and integrally. Steel heavy-duty air doors are installed among the heavy-duty supports of the shaft wall and controlled by a motor, and the motor is controlled by a pressure sensor or a high temperature smoke sensor or a liquid level sensor, thereby controlling the gas accident, fire accident and flood accident occurred on the stope working face within a minimum range and conducting treatment.

Description

Stope roadway automatic safety equipment

Technical field: stope roadway automatic safety equipment 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.

The utility model content: the purpose of the utility model 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.

Stope roadway automatic safety equipment is installed in that stope advances, the return airway road junction, in order to the generation of prevention and control stope " one through three prevention " accident; It is characterized in that being one by fixedly securing between heavy supporting and the roadway wall; The steel heavy air door is installed between the heavy supporting of roadway wall, and the steel heavy air door receives Electric Machine Control, and motor is by pressure sensor or high-temperature flue gas sensor or liquid level sensor control; When stope generation coal and gas outstanding; And when producing pressure and affacting on the pressure sensor, pressure sensor control motor cuts out the steel heavy air door rapidly by motor; When the stope breaking out of fire, high temperature or flue gas make high-temperature flue gas sensor control motor, rapidly the steel heavy air door are closed by motor; When stope generation floods, liquid level sensor control motor cuts out the steel heavy air door rapidly by motor; Thereby gas accident, fire incident, floods accident that stope is taken place are controlled at minimum zone, and handle.

Stope roadway automatic safety equipment; It is dark to it is characterized in that 0.2 meter of rib is stretched in heavy supporting, and the heavy air door doorframe between the heavy supporting and the connecting mode of heavy supporting are steel plate, link through screw; Steel heavy air door door leaf and doorframe match; Heavy air door doorframe and door leaf connect for strand, and door leaf and motor are closed door leaf through drive link, and sensor is through the operation of relay control motor.

Stope roadway automatic safety equipment 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 the equipment power supply of trend stope roadway automatic safety, when the down-hole restores electricity, and the automatic disconnection of batteries power supply.

Stope roadway automatic safety equipment compared with prior art has the following advantages:

1, stope roadway automatic safety equipment 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 stope, 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 air door.

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 the stope roadway automatic safety equipment can with underground monitoring monitoring networking, and be transferred to ground and carry out Artificial Control and open.

7, stope roadway automatic safety equipment 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.

Description of drawings:

Fig. 1: stope roadway automatic safety equipment sketch map.

1, heavy supporting; 2, roadway wall; 3, motor; 4, heavy air door;

5, pressure sensor; 6, high-temperature flue gas sensor; 7, liquid level sensor.

The specific embodiment: existing is the example explanation with the accompanying drawing: stope roadway automatic safety equipment; Be installed in that stope advances, the return airway road junction; In order to the generation of prevention and control stope " one through three prevention " accident, it is characterized in that being one that steel heavy air door (4) is installed between the heavy supporting (1) of roadway wall (2) by fixedly securing between heavy supporting (1) and the roadway wall (2); Steel heavy air door (4) receives motor (3) control; Motor (3) is by pressure sensor (5) or high-temperature flue gas sensor (6) or liquid level sensor (7) control, when stope generation coal and gas are given prominence to, and produces pressure and affacts pressure sensor (5) last time; Pressure sensor (5) control motor (3) cuts out steel heavy air door (4) rapidly by motor (3); When the stope breaking out of fire, high temperature or flue gas make high-temperature flue gas sensor (6) control motor, rapidly steel heavy air door (4) are closed by motor (3); When stope generation floods, liquid level sensor (7) control motor (3) cuts out steel heavy air door (4) rapidly by motor (3); Thereby gas accident, fire incident, floods accident that stope is taken place are controlled at minimum zone, and handle.

The place of stope roadway automatic safety equipment will be installed earlier clear up, and stope roadway automatic safety is equipped be installed in access adit is no more than 6 meters with the lining the scope, 0.2 meter of slotting is dark in the coal seam; Heavy supporting (1) is extend in the slotting of coal seam with 0.2 meter, lining; Realize that heavy supporting (1) and roadway wall (2) fixedly secure, the heavy air door (4) of all steel material open inward is installed again, in heavy supporting (1) to resist various disasters; Install and debug; Confirm errorless back unlatching air door, make air door be in normally open, promptly realize installing and using of stope roadway automatic safety equipment.
