Abstract
The invention discloses a mine protecting system which comprises a gas sensor, a controller and a power control device. The signal output end of the gas sensor is connected with signal collecting end of the controller. The signal input end of the power control device is connected with the signal output end of the controller. The mine protecting system has the advantages that existing manual multipoint mine detection is replaced, manual factors are avoided, all equipment connected with the power control device is shut down forcibly when gas content exceeds a set value, and the system is high in reliability and low in monitoring investment.
Description
Technical field
The present invention relates to mine safety-protection system field, particularly relate to a kind of mine protection system.
Background technology
Gas is discharge in the process of cutting coal colourless, tasteless, without odour, have four harm greatly: the one, can burn, cause mine fire; The 2nd, can explode, cause ore deposit to ruin people and die; The 3rd, when excessive concentration, can cause personnel's anoxia asphyxia, even dead; The 4th, can there is coal (rock) and Gas Outburst, destroy, stop up tunnel, even cause personnel's death by suffocation, gas explosion.
The means that realize methane gas content detection in prior art are generally realized by corresponding sensor, but in prior art, lack a kind of directly measure prevention in the time that methane gas content exceedes explosion limit minimum value methane gas by manufacturing process in inevitably frictional heat ignite.
Summary of the invention
For lacking a kind of direct measure prevention methane gas problem that inevitably frictional heat is ignited in by manufacturing process in the time that methane gas content exceedes explosion limit minimum value in above-mentioned prior art, the invention provides a kind of mine protection system.
For the problems referred to above; a kind of mine protection system provided by the invention reaches goal of the invention by following technical essential: a kind of mine protection system; comprise firedamp sensor, controller and power control unit; the signal output part of described firedamp sensor is connected with the signals collecting end of controller, and the signal input part of power control unit is connected with the signal output part of controller.
In upper module, the firedamp sensor arranging is for monitoring the methane gas content in mine, the controller arranging contrasts containing quantitative analysis for above methane gas, the electric power that the power control unit arranging is series at the electrical source of power of down-hole transmits on cable, like this, be convenient to realize controller in the time judging methane gas and exceed the minimum of explosion limit, to power control unit output brake signal, power control unit cuts off electrical source of power, to stop as dynamic power machine work such as drilling-production equipments, prevent frictional heat or the electric flame methane gas that ignites.Above process gets involved without human factor, and stops by force all equipment being connected with power control unit in the time that methane gas content exceedes setting value, and reliability is high and monitoring input is little.
Further technical scheme is:
Mine is carried out to multi-point monitoring, more than one of described firedamp sensor for ease of realizing.
Further, for monitoring main fuel gas, described firedamp sensor is methane transducer.
For making the present invention can play more direct forewarning function,, also comprise acoustic-optic alarm, the signal input part of described acoustic-optic alarm is connected with the signal output part of controller.
Intuitively reflect for ease of methane gas concentration, also comprise display unit, the signal input part of described display unit is connected on the signal output part of controller.
For ease of remote monitoring and critical-path analysis, also comprise delivery module, the signal input part of described delivery module is connected on the signal output part of controller.
The present invention has following beneficial effect:
The firedamp sensor arranging is for monitoring the methane gas content in mine, the controller arranging contrasts containing quantitative analysis for above methane gas, the electric power that the power control unit arranging is series at the electrical source of power of down-hole transmits on cable, like this, be convenient to realize controller in the time judging methane gas and exceed the minimum of explosion limit, to power control unit output brake signal, power control unit cuts off electrical source of power, to stop as dynamic power machine work such as drilling-production equipments, prevent frictional heat or the electric flame methane gas that ignites.Above process gets involved without human factor, and stops by force all equipment being connected with power control unit in the time that methane gas content exceedes setting value, and reliability is high and monitoring input is little.

Embodiment 2:
The present embodiment is further qualified on the basis of embodiment 1, as Fig. 1, mine is carried out to multi-point monitoring, more than one of described firedamp sensor for ease of realizing.
Further, for monitoring main fuel gas, described firedamp sensor is methane transducer.
For making the present invention can play more direct forewarning function,, also comprise acoustic-optic alarm, the signal input part of described acoustic-optic alarm is connected with the signal output part of controller.
Intuitively reflect for ease of methane gas concentration, also comprise display unit, the signal input part of described display unit is connected on the signal output part of controller.
For ease of remote monitoring and critical-path analysis, also comprise delivery module, the signal input part of described delivery module is connected on the signal output part of controller.
Above content is the further description of the present invention being done in conjunction with concrete preferred embodiment, can not assert that the specific embodiment of the present invention is confined to these explanations.For general technical staff of the technical field of the invention, not departing from other embodiments that draw under technical scheme of the present invention, all should be included in protection scope of the present invention.
