Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in fig. 1~fig. 5, a kind of coal mine gas automatic alarm device, including transparent plastic shell 1, battery case
2, controller 3, gas concentration sensor 4, fan 5, combined aural and visual alarm 6, in a upright side walls of the transparent plastic shell 1
Air inlet 7 is set, venthole 8 is set in the bottom sidewall of the transparent plastic shell 1, was fixedly installed on the air inlet 7
Strainer 10, the battery case 2, controller 3, gas concentration sensor 4, fan 5, combined aural and visual alarm 6 are arranged at transparent plastic
The inside of shell 1, the fan 5 are oppositely arranged with air inlet 7, and the gas concentration sensor 4 is oppositely arranged with fan 5, institute
The power output end for stating battery case 2 is electrically connected by conducting wire with controller 3, the gas concentration sensor 4, fan 5, sound
Light crossing-signal 6 is electrically connected by conducting wire with controller 3.
Preferably, the controller 3 further includes operation button 9, and 1 top of transparent plastic shell is arranged in operation button 9
On side wall.
Preferably, fixing buckle 12 is arranged in the external of the transparent plastic shell 1 upright side walls opposite with air inlet 7.
Preferably, the battery case 2 further includes battery case lid 11, the setting of battery case lid 11 transparent plastic shell 1 with into
In the opposite upright side walls of stomata 7.
The use operating method of the utility model:
Before direct labor will carry out production work into underground coal mine, by the battery of the battery case 2 on the utility model
Box cover 11 is opened, and battery is taken to be put into battery case 2, then the fixation of battery case lid 11 is covered on battery case 2, and battery is consolidated
It is placed in battery case 2, the battery case lid 11 that being arranged flexibly to dismantle can extend the service life of the utility model, and conveniently
User replaces or dismantles at any time battery, when not using, battery can be taken out out of battery case 2, and it is practical new to extend this
The service life of type.
After battery installs, direct labor passes through fixing buckle 12 using belt or rope, and the utility model is fixed on
Loins.
Battery case lid 11 and fixing buckle 12 are arranged in the same side upright side walls of transparent plastic shell 1, so can be with
It prevents battery case lid 11 from being touched by other articles, battery case lid 11 is caused to fall off, and further result in the battery in battery case 2
It is fallen out of battery case 2, use is more secure, more stable.
Direct labor starts controller 3 by operation button 9, and further presets controller 3 to gas density
Then alarming value starts fan 5.
Direct labor carries the utility model and enters underground coal mine, because fan 5 and air inlet 7 are oppositely arranged, so operating
In fan 5 gas made in mine is sucked into air inlet 7, the gas in mine will be by 10 mistake of filter screen when sucking air inlet 7
Filter the solid matters such as dust.
It will be entered inside transparent plastic shell 1 by the filtered gas of filter screen 10, because of gas concentration sensor 4 and fan
5 are oppositely arranged, so gas concentration sensor 4 is flowed directly by the gas that fan 5 sucks inside transparent plastic shell 1, so that
Gas concentration sensor 4 can contact more abundant, the detection of gas concentration sensor 4 with the gas entered inside transparent plastic shell 1
The numerical value arrived is more acurrate.Then the gas inside transparent plastic shell 1 is again from the outlet in the bottom sidewall of transparent plastic shell 1
Hole 8 is flowed out, and stomata 8, which is arranged in the bottom sidewall of transparent plastic shell 1, positive effect, can prevent in use environment in this way
Dust decline when fall into transparent plastic shell 1, extend the service life of the utility model.
The gas density data-signal that gas concentration sensor 4 will test in real time passes to controller 3, works as gas density
4 real-time detection of sensor to gas density data reach 3 preset alarming value of controller when, controller 3 is immediately controlled
Combined aural and visual alarm 6 starts, and combined aural and visual alarm 6 issues alarm and alarm light, carries out gas density early warning to user, reminds
User takes emergency safety emergency measure.
