Description
Technical field
The utility model relates to mining tunnel device of explosion suppression technical field, particularly relates to the probe on a kind of mining tunnel device of explosion suppression.
Background technology
The usual construction environment in colliery is severe, and be the Different high risk sites occurring security incident, the gas density in coal mine roadway constantly accumulates in work progress, needs high-power blower periodically to perform air intake and return air to ensure that gas density in tunnel is within safety value.But some power equipments will be used in the work progress of colliery, after the gas density in tunnel reaches certain value, minimum electric spark also can cause the brute force blast of gas, cause serious casualties and property loss, so obtain detonator signal by high-efficiency appliance and suppress blast to become the requisite measure of safety of coal mines construction in time.Wherein, obtain detonator signal accurately and timely and seem particularly important, this is that coal mine roadway device of explosion suppression carries out datonation-inhibition prerequisite in real time, inerrably.
There are two important feature the moment of blast: powerful flame and pressure.When only having these two conditions to meet, just may there is blast simultaneously.If the detonator signal that whole explosion suppression system detects only is directed to flame, then the electric spark occurred in work progress or the artificial unexpected flame manufactured all may make system occur that fire alarm is reported by mistake, and this can exist risk in the reliability of system works; If the detonator signal detected only is directed to pressure, then the atmospheric pressure that in coal mine roadway, periodic air intake, return air cause changes the detection of also possibility influential system.
Utility model content
For the weak point that prior art exists, the purpose of this utility model is to provide the probe on a kind of mining tunnel device of explosion suppression, this probe can detect flame and pressure signal simultaneously, improves in coal mine roadway the reliability of detonator signal and accuracy.
The purpose of this utility model is achieved through the following technical solutions:
A probe on mining tunnel device of explosion suppression, comprises shell, installation panel and tightening cover, and the installation panel of shell is provided with at least one ultraviolet pipe and at least one pressure detector, and described installation panel is locked at outer casing end by tightening cover; Ultraviolet detector, photoelectrical coupler, pull-up resistor and electromagnetic switch is provided with in described ultraviolet pipe, described ultraviolet detector is electrically connected with photoelectrical coupler, photoelectrical coupler inside has the metal-oxide-semiconductor be electrically connected with ultraviolet detector, metal-oxide-semiconductor is electrically connected with pull-up resistor, electromagnetic switch respectively, and described pull-up resistor is used for the level signal switching signal of ultraviolet pipe electromagnetic switch being changed into 0V/5V; Pressure detector on described installation panel is for detecting air pressure and changing the air pressure detected into voltage signal.
In order to realize the utility model better, the quantity of described pressure detector is two, and the quantity of ultraviolet pipe is six, and six ultraviolet pipes are evenly arranged on the installation panel of shell.
Further technical scheme is: the installation panel of described shell is provided with working station indicator.
For the ease of the installation of whole probe, the housing of described shell is fixed welding and be provided with link device.
The utility model comparatively prior art is compared, and has the following advantages and beneficial effect:
This probe can set respective thresholds, detect flame and pressure signal simultaneously, and the final fire alarm that exports is carried out datonation-inhibition, the system of ensure that can detect detonation factors comprehensively and accurately export fire alarm, improves in coal mine roadway the reliability of detonator signal and accuracy.
