Background technology
Existing coal gas, major part is canned or pipeline is directly carried, use very convenient, but when gas leak, early warning can not be carried out timely, namely allow to report to the police timely, if unmanned or slightly gas poisoning cannot be moved time, cannot the cut-out source of the gas when gas leakage in time, make to there is larger potential safety hazard, and do not carry out cut-out source of the gas, also can cause a large amount of wastings of resources and property loss.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of for detecting gas leak and the automatic device cutting off coal gas source, thus overcome the shortcoming cannot carrying out cutting off source of the gas when gas leak.
For achieving the above object, the invention provides a kind of for detecting gas leak and the automatic device cutting off coal gas source, comprising: coal gas detector, for detecting gas leak; Single-chip microcomputer, it is connected with described coal gas detector, for receiving the signal of described coal gas detector; And gas-cutting off device, it comprises: bracing frame, and it is installed on the valve place of the pipeline of conveying coal gas; And motor, it is installed on support frame as described above, and be provided with on the transmission shaft of described motor and can be nested the external member of joining with the switch handle of described valve, wherein said motor is connected with by positive/negative turn of motor described in described Single-chip Controlling with described single-chip microcomputer, and then controls the opening/closing of described valve.
In technique scheme, also comprise an alarm, it is connected with described single-chip microcomputer.
In technique scheme, also comprise an accumulator, this accumulator is connected with described single-chip microcomputer, described motor, described alarm and described coal gas detector respectively.
In technique scheme, when described external member cover is assigned on described switch handle, the axis of the axis of the transmission shaft of described motor and the turning axle of described valve, on same straight line, makes described motor can drive described valve open/closedown by external member.
Compared with prior art, the present invention has following beneficial effect: the device in the present invention, detect gas leak by coal gas detector, receive leakage signal by invention thus control gas-cutting off device and will control the valve closing that opens or closes of coal gas, and then play the object cutting off coal gas source.
