Abstract
The utility model discloses full-automatic safety equipment for a driving face roadway. The safety equipment is arranged in a range of 6m away from an air return access adit of the driving face roadway and is used for preventing fire hazard, flood hazard, coal and gas outburst and other accidents on the driving face. The equipment is characterized in that: heavy supports are firmly fixed with four walls of the roadway into a whole; a steel heavy air door is arranged between the heavy supports on the four walls of the roadway and is controlled by a motor; the motor is controlled by a high-temperature flue gas sensor. When a fire accident occurs on the driving face, high-temperature flue gas acts on the high-temperature flue gas sensor, the motor is controlled by the high-temperature flue gas sensor, and the steel heavy air door is rapidly closed through the motor.
Description
Technical field: driving face 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 retrieval comprehensively both at home and abroad, the equipment of the various natural calamities of prevention is a lot of under the coal mine, but can be used in the outstanding equipment of Automatic Control fire, floods, coal and gas; Do not find all that 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 the measure means are a lot of when coal taking place giving prominence to gas; Can't fire often occur and enlarge with disaster control within the specific limits but also exist, floods flood whole mine; Gas is outstanding to cause 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.
Driving face roadway automatic safety equipment is installed in the advancing of driving face, return airway road junction 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 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 controlled by the high-temperature flue gas sensor; When driving face breaking out of fire accident; High temperature or flue gas affact on the high-temperature flue gas sensor, and high-temperature flue gas sensor control motor cuts out the steel heavy air door rapidly by motor.
Driving face 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.
Driving face 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 driving face roadway automatic safety, when the down-hole restores electricity, and the automatic disconnection of batteries power supply.
Driving face roadway automatic safety equipment compared with prior art has the following advantages:
1, driving face 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 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 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 driving face roadway automatic safety equipment can with underground monitoring monitoring networking, and be transferred to ground and carry out Artificial Control and open.
7, driving face 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: driving face roadway automatic safety equipment sketch map.
1, heavy supporting; 2, roadway wall; 3, motor;
4, heavy air door; 5, high-temperature flue gas sensor.
The specific embodiment: existing is the example explanation with the accompanying drawing: driving face roadway automatic safety equipment; The return airway road junction that is installed in driving face is inward in 6 meters the scope; Accident such as give prominence in order to prevention driving face fire, floods, coal and gas, 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 high-temperature flue gas sensor (5) control, and when driving face breaking out of fire accident, high temperature or flue gas affact on the high-temperature flue gas sensor (5); High-temperature flue gas sensor (5) control motor (3) cuts out steel heavy air door (4) rapidly by motor (3).
The place of driving face roadway automatic safety equipment will be installed earlier clear up, and driving face 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 driving face roadway automatic safety equipment.
Claims (2)
