Full hidden danger, there is provided effectively time guarantee.
Description of the drawings
Fig. 1 is this utility model structural representation.
Specific embodiment
Embodiment 1
A kind of vehicular methane monitor breaker that the present embodiment is provided, structure is as shown in figure 1, mainly include that cutoff instrument is explosion-proof outer
Shell 1, methane transducer 2 and methane Anti-blasting alarming device 3, are provided with host circuit and power autonomous in cutoff instrument explosion-resistant enclosure
Group, cutoff instrument explosion-resistant enclosure side is provided with exchange input port 4 and power-off delivery outlet 5, and the opposite side of cutoff instrument explosion-resistant enclosure is provided with
Detection signal port 6 and anti-explosion alarming seat, install light alarm device 7, detection signal end on the upper surface of cutoff instrument explosion-resistant enclosure
Mouth connects methane transducer 2 by flame-retardant communication cable 8, and methane Anti-blasting alarming device 3 is installed on anti-explosion alarming seat, and methane is explosion-proof
Alarm device is provided with Backup Power Switch 9 and auto/man transfer switch 10.External power source, controlled device, connecting line are used
Cable is installed through the method for clamp nut；Methane transducer connection cable is connected to power-off through the method for clamp nut
Instrument main frame, adds warning circuit in cutoff instrument host circuit, then methane explosion-proof alarm, manual-automatic switch, stand-by power supply
Switch is arranged in Anti-blasting alarming device by explosion-proof wiring post.
The present embodiment has the occasion of methane and coal dust explosion hazard suitable for colliery, and connects equipment low-concentration methane
Sensor is connected, and on battery locomotive, the gas density of energy automatic monitor for continuously locomotive position works as gas density
When meeting or exceeding preset alarming value, the explosion-proof seat inner sensor of cutoff instrument sends immediately sound, visual alarm, when gas density reaches
To or during more than preset power-down value, cutoff instrument cuts off immediately electricity for locomotive, to guarantee production safety.When gas density falls back to
When below preset solution drop lock, cutoff instrument automatic unlocking recovers electricity for locomotive, and proceeds monitoring.Cutoff instrument is power autonomous
Use time increases to more than 6 hours, facilitates underground work personnel to exclude methane and maintenance of equipment operation, and to down-hole safety is excluded
Hidden danger, can ensure that the safety that long-time is used.
In addition to the implementation, this utility model can also have other embodiment.All employing equivalents or equivalent change
The technical scheme to be formed is changed, the protection domain of this utility model requirement is all fallen within.
