Abstract
The utility model discloses a mining vehicle mounted methane breaker host machine, comprising a methane sensor, a mainboard, a power relay board, and a batter pack. The batter pack is connected with the mainboard through the power relay board. The methane sensor is connected with a NAND gate and a frequency divider in sequence, the NAND gate and the frequency divider being disposed on the mainboard. The frequency divider is connected with a singlechip. The methane breaker host machine can continuously and automatically detect methane concentration of a location of an engine, and sends different instructions according to the methane concentration, thereby achieving a purpose of safety production, and a purpose of converting input frequency of 200-10000 Hz to intrinsic safe output frequency of 6-24 Hz is achieved.
Description
Technical field
The utility model relates to methane-monitor breaker field, is specially a kind of mining vehicular methane-monitor breaker main frame.
Background technology
Methane (CH4) is the principal ingredient of coal-mine gas, accounts for 83%-89%, so it has been generally acknowledged that methane is exactly gas.The coal mine gas from explosion taking place frequently has caused a large amount of personnel's injures and deaths, great property loss and serious social influence, has caused the extensive concern of international community.For this reason, the particularly serious accident in prevention and control colliery has become the significant problem of being badly in need of solution in industry.
In order to adapt to coal industry to mechanization and automation direction development, guarantee the production safety of mine, prevent the generation of gas explosion accident, the research of mining methane sensor and design never stopped.
Summary of the invention
The utility model, for above weak point, provides a kind of mining vehicular methane-monitor breaker main frame, can detect continuously and automatically the methane concentration of locomotive position, sends different instructions in time according to the difference of methane concentration, reaches the object of safety in production.
The utility model solves the technical scheme that its technical matters adopts: a kind of mining vehicular methane-monitor breaker main frame, include methane transducer, mainboard, power supply relay board, electric battery, described electric battery connects mainboard by power supply relay board, described methane transducer is connected in Sheffer stroke gate and the frequency divider on mainboard successively, and described frequency divider connects single-chip microcomputer.
On described single-chip microcomputer, be connected with photoelectrical coupler.
On described single-chip microcomputer, be connected with relay switch.
The utility model is according to the relevant regulations of GB3836-2010 < < explosive gas atmosphere consumer > > standard, be arranged on underground movable equipment, supporting methane transducers etc. form methane concentration, overload alarm detects, with like product comparison, its exclusive bifrequency output can realize general with home and overseas; By Sheffer stroke gate, frequency divider and single-chip microcomputer, incoming frequency 200-10000HZ can be converted to the intrinsic safety output frequency of 6-24Hz, can realize the equipment interconnection of the 6Hz-24Hz output frequency adopting in the world.
Accompanying drawing explanation
It shown in Fig. 1, is schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Be illustrated in figure 1 a specific embodiment of the present utility model, a kind of mining vehicular methane-monitor breaker main frame, include methane transducer 1, mainboard 2, power supply relay board 3, electric battery 4, described electric battery 4 connects mainboard 2 by power supply relay board 3, and described methane transducer 1 is connected in Sheffer stroke gate 5 and the frequency divider 6 on mainboard 2 successively, described frequency divider 6 connects single-chip microcomputer 7, on described single-chip microcomputer 7, is connected with photoelectrical coupler or relay switch.
The utility model is used in the place that colliery has methane to overflow, be mounted in the methane detector device on mining single track locomotive, can detect continuously and automatically the methane concentration of locomotive position, when methane concentration reaches preset alarming value, connected sensor can send sound and light alarm signal; When methane concentration reaches preset power-down value, instrument can be cut off the electricity supply; When the concentration of methane returns to preset warning or power-down value when following, instrument can automatically terminate reports to the police or power-off.
The utility model adopts double circuit to control, and when any road Sensor monitoring concentration is greater than 1.5%, cutoff instrument just should cut off device power supply (DPS) in time; When concentration is between 1.0%-1.5%, answer and alarm.DJ-C-4.0/24-(Z) is mining, and vehicular methane-monitor breaker adopts double circuit signal protection to control, and with failure monitoring warning function.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
