Abstract
An underground emergency acousto-optic warning system comprises an acousto-optic warning box arranged in an underground roadway, a PLC arranged in an anti-explosion power supply box and detection sensors arranged in pairs on the side wall of the roadway in the direction of the roadway in a front-and-back mode. The detection sensors and the acousto-optic warning box are connected with the PLC in wired mode, and the PLC and the acousto-optic warning box are connected with a power supply. When underground accidents happen, by means of acousto-optic warning and prompts at intersections of roadways, underground personnel are guided to distinguish the advancing direction and can reach a safe place quickly, and casualties are reduced. When the system is used, the system is not influenced by the situations such as power is cut off underground and sights are blocked by smoke and dust. The system is suitable for various underground on-site environments, can be used for acousto-optic warning and prompting in emergency, and can serve as a roadway indicator board in safety.
Description
Technical field
The utility model relates to the emergent audible and visual alarm system in a kind of down-hole, when having an accident under mine, guides the personnel of taking refuge to go to safety place in intersection, tunnel.
Background technology
Mine down-hole tunnel is more, and crisscross.When down-hole has an accident, during personnel's emergency escape, the tunnel that must avert danger, arrives safety place with the fastest speed, the shortest path.When often accident occurs, be accompanied by the situations such as down-hole has a power failure, tunnel flue dust fills the air, personnel shortage confusion, only rely on self memory and conventional direction board, the personnel that take refuge cannot distinguish direction in underworkings intersection, extend the escape time, increased the danger of self.So, emergent warning system is installed in intersection, tunnel, judgement personnel direct of travel, and point out in the mode of acousto-optic, it is very important that the guiding personnel that take refuge arrive rapidly safety place.
Summary of the invention
The purpose of this utility model is to provide the emergent audible and visual alarm system in a kind of down-hole, in the time of can having an accident in down-hole, overcome the impact of the site environments such as down-hole has a power failure, personnel are unsighted, in intersection, tunnel, in the mode of acousto-optic, point out, guide the personnel of taking refuge to go to rapidly safety place.
The purpose of this utility model realizes as follows: this down-hole audible and visual alarm system of meeting an urgent need, comprise the sound and light alarm case being arranged in underworkings, separately there is the PLC controller of device in explosion-proof power box, have along roadway direction front and back detecting sensor arranged in pairs on the sidewall of tunnel, detecting sensor, sound and light alarm case are by wired connection PLC controller, and PLC controller, sound and light alarm case connect power supply.
Power supply is comprised of ups power and mine public power.
Each mouth in intersection, tunnel all has a pair of detecting sensor, a sound and light alarm case, and all mouthfuls of this intersection, tunnel share a PLC controller, a ups power, a power supply explosion-proof tank.The every pair of detecting sensor is arranged before and after roadway direction, is arranged on each access adit sidewall, mainly for detection of this access adit, whether has personnel's dealing, and dealing personnel advance toward access adit, or leaves from access adit, judges personnel's direct of travel.Each sound and light alarm case is arranged on each access adit top, is mainly used in the destination that this turnout, access adit the place ahead of screen display leads to, and the prompting of sounding.The power supply of sound and light alarm case and PLC controller is simultaneously from mine public power and ups power.When access adit is without personnel, or detecting sensor has been when personnel having been detected and having left from access adit, the destination that sound and light alarm case keeps this turnout, access adit the place ahead of screen display to lead to always.When detecting sensor has detected personnel and has advanced toward access adit, the prompting of sounding in the destination that keeps this turnout, access adit the place ahead of screen display to lead to of sound and light alarm case, the time delay after the personnel that can't detect advance toward access adit of this auditory tone cues stops.Ore deposit is underground power supply used when normal, and the power supply of sound and light alarm case and PLC controller is all from mine public power, and ups power charges from mine public power simultaneously.When the underground power supply used termination in ore deposit, sound and light alarm case and PLC controller all transfer ups power power supply automatically to.
When the utility model can have an accident under mine, in each intersection, tunnel, by audible and visual alarm, point out, guiding personnel in the pit distinguishes direction of advance, arrives rapidly safety place, reduces casualties.During use, be not subject to the impact of the situations such as down-hole power-off, flue dust obstruct the view, adapt to various site environments under mine.Both can be used as audible and visual alarm prompting when urgent, also can be used as tunnel direction board when safe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, the utility model comprises detecting sensor 1, PLC controller 3, sound and light alarm case 2, ups power 4 and explosion-proof power box 5.A sound and light alarm case 2 is installed in crown center position at each access adit, on the sidewall of each access adit, before and after roadway direction, a pair of detecting sensor 1 is installed, PLC controller 3 devices are in explosion-proof power box 5, detecting sensor 1, sound and light alarm case 2 is by wired connection PLC controller 3, PLC controller 3, sound and light alarm case 2 connects the power supply being comprised of ups power 4 and mine public power, sound and light alarm case 2 is all connected with mine public power by ups power 4 with explosion-proof power box 5, intersection, a tunnel shares a PLC controller 3, a ups power 4 and an explosion-proof power box 5.Each sound and light alarm case 2 remains the destination that this each turnout, access adit the place ahead of screen display leads to.When detecting sensor 1 does not detect access adit and has personnel, each several part is reactionless; When detecting sensor 1 detects access adit and has personnel, by the priority detection order of a pair of detecting sensor 1, by PLC controller 3 these personnel's direct of travels of judgement: if personnel leave from this access adit, each several part is reactionless; If personnel advance toward access adit, the sound and light alarm case 2 of this access adit alarm of sounding, the destination that prompting each turnout, the place ahead leads to.When mine public power, power when normal, each several part is powered by mine public power; When mine public power disconnects, each several part is all automatically converted to ups power 4 power supplies.
