Abstract
The utility model discloses a safety monitor device for controlling the on-off state of a power source of electromechanical equipment underground a coal mine, particularly relates to a power-off control system of mining equipment, and belongs to the technical field of safety monitoring. The power-off control system of the mining equipment comprises an airborne electricity breaker with the wireless transmission function, wherein the airborne electricity breaker is installed on a coal mining unit inside a roadway; a power cable of the coal mining unit is connected with power transformation equipment outside the roadway. The power-off control system of the mining equipment further comprises a wireless receiving device for receiving control signals of a methane sensor, the wireless receiving device is installed inside the roadway and is connected with a power-off control system body located on one side of the power transformation equipment through signal cables arranged inside the roadway, and the power-off control system body can carry out power-off control over the power transformation equipment. By the adoption of the structure, the operation environment of the electromechanical equipment in the roadway is monitored continuously, the signals are transmitted in a wireless mode, the production can be carried out normally, the environmental conditions are monitored in a remote and real-time mode, the structure is simple, using is reliable, and safety of downhole operation staff and normal production are ensured.
Description
Technical field
The utility model relates to the safety monitoring device of controlling dynamo-electric device power supply (DPS) on off operating mode under a kind of coal mine, and specifically a kind of mining equipment power-off control system, belongs to safety monitoring technology field.
Background technology
Along with improving constantly of pit mining Mechanization Level, it is more and more and complicated that down-hole giant mechanical and electrical equipment also becomes, under personnel's the most important major premise of life security, to monitor automatically the running environment of underground equipment, to guarantee safety and normal production of underground operators, the gas-monitoring equipment of installing in coal mine underground mobile plant equipment is at present unreasonable because structure arranges, cannot in time monitoring information transmission be arrived to ground monitoring center on the one hand, in addition on the one hand, power-off completely after sensor detects methane concentration and exceeds standard, also be just difficult to guarantee safety and normal production of underground operators.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of rational in infrastructure, use reliably, can guarantee safety and the normal mining equipment power-off control system of producing of underground operators.
In order to solve the problems of the technologies described above, mining equipment power-off control system of the present utility model, comprise and be arranged on the airborne cutoff instrument with wireless transmission function on coal mining unit in tunnel, power cable on coal mining unit is connected with the converting equipment outside tunnel, also comprise the radio receiver that can receive methane transducer control signal being arranged in tunnel, radio receiver is connected on the power-off control system that is positioned at converting equipment one side by the signal cable being arranged in tunnel, and power-off control system can carry out power-off control to converting equipment.
Described radio receiver is positioned at a side of power cable and is placed in the offside of the work plane in tunnel.
Adopt after above-mentioned structure, owing to thering is the airborne cutoff instrument of wireless receiving function on coal mining unit of the present utility model and being arranged on the radio receiver that can receive methane transducer control signal in tunnel, the mode by wireless transmission after methane concentration that sensor can be detected thus passes to information the radio receiver of haulage drift, when making airborne power cutoff device control power-off, the converting equipment that is positioned at working section sub station is simultaneously controlled, the cable of avoiding entering work plane is charged, in dual control mode, guarantee exploiting field equipment security of operation, and, by the control appliance of working section sub station, the transfer of data that coal-winning machine upper sensor is gathered is to ground central station, by the electromechanical equipment running environment to tunnel of living in, monitor continuously, signal wireless transmission, be convenient to produce and when normally carrying out, realize environmental aspect remote real-time monitoring, it is rational in infrastructure, use reliable, safety and normal production of underground operators have been guaranteed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model mining equipment power-off control system.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, mining equipment power-off control system of the present utility model is described in further detail.
As shown in the figure, mining equipment power-off control system of the present utility model, comprise the coal mining unit 1 that is arranged on tunnel inner working face, coal mining unit 1 can move up and down along work plane, the airborne cutoff instrument 2 with wireless transmission function on coal mining unit 1, on coal mining unit 1, be also provided with the sensor that can detect methane concentration, power cable 3 on coal mining unit 1 is connected with the converting equipment 4 outside tunnel, also comprise the radio receiver that can receive methane transducer control signal 5 being arranged in tunnel, radio receiver 5 is connected on the power-off control system 7 that is positioned at converting equipment 4 one sides by the signal cable 6 being arranged in tunnel, power-off control system 7 can carry out power-off control to converting equipment 4, preferred radio receiver 5 is positioned at a side of power cable 2 and is placed in the offside of the work plane in tunnel.
By the setting of the utility model said structure, can the mode by wireless transmission after methane concentration be detected and information is passed to the radio receiver in tunnel by being arranged on sensor on portable coal-winning machine, when making airborne power cutoff device control power-off, the converting equipment that is positioned at working section sub station is simultaneously controlled, the cable of avoiding entering work plane is charged, in dual control mode, guarantee exploiting field equipment security of operation, and, by the control appliance of working section sub station, the transfer of data that coal-winning machine upper sensor is gathered is to ground central station, solved thus the gas-monitoring equipment of installing in current coal mine underground mobile plant equipment and cannot in time monitoring information transmission have been arrived to the difficult problem at ground monitoring center.
