When the gas concentration of gas for an operation area exceeds a specified limit value, the safety lamp twinkles automatically and carries out acoustic and optical alarming.
Description
Technical field
The utility model relates to a kind of safe instrument, particularly a kind of portable mine safety instrument that has gas alarming, searches and rescues illumination functions.
Background technology
Existing mine lamp weak point service time 9～20 hours after mine disaster takes place, just can not continue to provide illumination, and be unfavorable for the carrying out of search-and-rescue work in maximum about 20 hours.And mine lamp does not have the function of sound and light alarm after gas density exceeds standard at present, can't before taking place, gas accident report to the police in advance, and be that the miner withdraws in advance.
The utility model content
The purpose of this utility model provides a kind of portable mine safety instrument that has gas alarming, searches and rescues illumination functions.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of portable mine safety instrument comprises lamp body, it is characterized in that: described lamp body top is provided with the search and rescue lamp, searches and rescues lamp one side and is provided with miniature gas probe, and sidepiece is provided with the audible alarm buzzer.
Preferably, described safe instrument back is provided with the bayonet socket that is fit to be positioned between mine workman waistband.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
When the methane gas concentration overshoot limit value in operation zone, this safety lamp is just glittering automatically, and carry out sound, light is reported to the police, and to point out operating personnel's safe escape deathtrap early, reaches the effect that prevents trouble before it happens.After mine caved in, the operating personnel was stranded when being pressed in the workspace, and this lamp can glimmer luminous more than 8 days continuously, for the rescue worker in time provides direction and position accurately, has greatly reduced the injures and deaths and the economic loss of accident.This lamp safety, reliable, easy to carry, be called by mine operation personnel " help lamp ".
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Among the figure: R: resistor, C: capacitor, V: triode, D: diode, F: on-off circuit, IC: integration module, H: gas density probe, HG: light sensor, L: loudspeaker, T:LED luminous tube.
The specific embodiment
According to embodiment the utility model is described in further detail below.
As shown in Figure 1, a kind of portable mine safety instrument comprises lamp body 1, lamp body 1 top is provided with searches and rescues lamp 4, search and rescue lamp 4 one sides and be provided with miniature gas probe 5, sidepiece is provided with audible alarm buzzer 3, and safe instrument back is provided with the bayonet socket 2 that is fit to be positioned between mine workman waistband.
As shown in Figure 2, when mine have an accident stop power supply after because the down-hole do not have illumination, light sensor HG reverse operation, LED luminous tube T starts working, and lights continuously more than 8 days, for search-and-rescue work provides convenience.When methane gas concentration under the mine surpassed setting value, gas density probe H started working, and IC provides comparison signal for integration module, opens on-off circuit F, amplified through triode V, promoted loudspeaker L and reported to the police.
When the methane gas concentration overshoot limit value in operation zone, this safety lamp is just glittering automatically, and carry out sound, light is reported to the police, and to point out operating personnel's safe escape deathtrap early, reaches the effect that prevents trouble before it happens.After mine caved in, the operating personnel was stranded when being pressed in the workspace, and this lamp can glimmer luminous more than 8 days continuously, for the rescue worker in time provides direction and position accurately, has greatly reduced the injures and deaths and the economic loss of accident.This lamp safety, reliable, easy to carry, be called by mine operation personnel " help lamp ".
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other multi-form variation and changes on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model amplifies out or change still are in protection domain of the present utility model.
