Summary of the invention
In view of this, the utility model proposes the interval acoustic-optic alarm of a kind of Air Throttle in Mine Pit, utilize tongue tube and miniature relay self-control opening and closing sensor, optimize warning system.
The utility model provides a kind of Air Throttle in Mine Pit interval acoustic-optic alarm, and comprising: power supply, sensor and alarm module, sensor comprises tongue tube, relay and permanent magnet, and alarm module comprises LED circuitboard, audio power amplifier and speech chip; Wherein, power cathode connects tongue tube one end and relay common port, tongue tube other end contact relay negative pole, positive source contact relay positive pole; Green light negative pole contact relay on LED circuitboard is often made war, and the traffic lights common point of LED circuitboard connects audio power amplifier positive pole, and audio power amplifier positive pole connects positive source; Red light negative pole on LED circuitboard connects audio power amplifier negative pole, the normally closed point of audio power amplifier negative pole contact relay, and traffic lights common point connects audio power amplifier positive pole, and audio power amplifier positive pole connects positive source; Further, the installation site of permanent magnet and the opening and closing of air door servo-actuated, under air door closed condition, permanent magnet and tongue tube are contiguous, under door opening state, permanent magnet and tongue tube away from.
Preferably, wherein said audio power amplifier is connected with speech chip and loudspeaker.
Preferably, wherein said alarm module is placed in warning device case, and the casing of warning device case has explosion-resistant enclosure, and casing front is transparent flame-retarding material.
Preferably, wherein said power acquisition 127V explosion-proof power box, get interchange 127V power supply during work and enter explosion-proof power box, the rectifier power source input side in access power supply box, outlet side exports direct current 24V/12V, is each assembly power supply of device.
Preferably, wherein said relay adopts 24V miniature relay.
The beneficial effects of the utility model: the interval acoustic-optic alarm of Air Throttle in Mine Pit of the present utility model utilizes tongue tube, miniature relay to make opening and closing sensor by oneself, sensitivity meets user demand under mine, result of use is good, its device structure is simple, material easily obtains, maintenance cost is low, can long-term work and failure rate is low, mal-condition under mine can be adapted to, electric pressure is used to reduce after system optimization, circuit running current reduces, energy-saving and cost-reducing, is applicable to coal mine underground air door and opens closed acousto-optic hint.
Accompanying drawing explanation
Fig. 1 and Fig. 2 is the structured flowchart of the interval acoustic-optic alarm of Air Throttle in Mine Pit of the utility model embodiment.
Fig. 3 is the circuit connection diagram of the interval acoustic-optic alarm of Air Throttle in Mine Pit of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the technical solution of the utility model is described in detail.
Fig. 1 and Fig. 2 shows the structure chart of the interval acoustic-optic alarm of Air Throttle in Mine Pit of the utility model embodiment, device mainly comprises: power supply, sensor and alarm module, wherein, the sensor used utilizes the homemade opening and closing sensor of tongue tube, relay and permanent magnetic iron; Alarm module is placed in warning device case, and box house has LED circuitboard, audio power amplifier, speech chip, loudspeaker etc., and casing has square explosion-resistant enclosure, and front is transparent flame-retarding material, traffic lights display in visible case; Power acquisition 127V explosion-proof power box, get interchange 127V power supply from underground coal mine during work and enter explosion-proof power box, the rectifier power source input side in access power supply box, outlet side exports direct current 24V/12V, is each assembly power supply.
With reference to figure 3, wherein, Switching Power Supply direct current negative pole connects tongue tube one end and relay common port, tongue tube other end contact relay negative pole; Switching Power Supply direct-flow positive pole contact relay positive pole.
Wherein, green light system for LED circuitboard: green light negative pole contact relay is often made war, traffic lights common point connects audio power amplifier (comprising voice plate and loudspeaker) positive pole, by audio power amplifier positive pole Returning switch positive source, when permanent magnet is near tongue tube, green light is lighted.
Wherein, red light system for LED circuitboard: red light negative pole connects audio power amplifier negative pole, the normally closed point of audio power amplifier negative pole contact relay is (when permanent magnet is near tongue tube, the normally closed disconnection of relay, red light and voice system dead electricity, green light obtains electric lighting), traffic lights common point connects audio power amplifier positive pole, by audio power amplifier positive pole Returning switch positive source.
Wherein, the relay of sensor can adopt 24V miniature relay.
During operation, when air door is in closed condition, permanent magnet and tongue tube vicinity, reed switch relay, by permanent magnet adhesive, makes green light Chang Liang; When door opening, permanent magnet is removed, then green light dead electricity, red light, speech chip and power amplifier obtain electric, perform and realize sound and light alarm.Here, red light, speech chip and power amplifier composition minimum unit, realizes sound and light of alarm, reminds the other side's air door to open.
