Abstract
The utility model provides a gas alarm device, comprising a gas sensor, a signal processing circuit, an accumulator cover, a wireless emitter, a wireless receiver and a luminophor. The output end of the signal processing circuit is connected with the input end of the emitter, and the signal processing circuit, the emitter and the gas sensor together form a sensing emission module which is arranged in a shell body. The sensing emission module is arranged on the accumulator cover, and corresponding power electrode terminals are arranged between the sensing emission module and the accumulator cover. The output end of the receiver is connected with the luminophor, and the receiving alarm module is connected with the front edge of the helmet of a miner. The gas sensor and the receiver are installed in the independent shell body and are connected with the accumulator cover through a removable structure, and the alarm signal is output in a wireless way. The gas sensor and the emitter shell body are easily demounted for solely calibrating when the alarm is calibrated, which is convenient for calibrating. The light alarm signal is more obvious.

Background technology
The light of existing gas alarming device is reported to the police not directly perceived, and acoustic alarm is not heard clear in the down-hole; The feeding calibrating gas of will uncapping when at every turn the drift of firedamp sensor being calibrated just can carry out, and is very inconvenient.
Summary of the invention
The purpose of this utility model just provides a kind of novel gas alarming device, inconvenience and the unconspicuous problem of alerting signal when calibrating to solve.
The technical solution of the utility model is: a kind of novel gas alarming device, comprise firedamp sensor, signal processing circuit and battery cap, the signal end of sensor is connected with the input end of signal processing circuit, in signal processing circuit, be provided with the alarm set point point of adjustment, also comprise transmitting set, radio receiver and luminophor, the output terminal of described signal processing circuit is connected with the input end of transmitter, and both and firedamp sensor constitute the sensing transmitter module jointly and place in the housing; This sensing transmitter module is loaded on the described battery cap, is equipped with corresponding power electrode terminal between sensing transmitter module and the battery cap; Output terminal at receiver is connected with luminophor, and both form receiving alarm module, and this receiving alarm module is connected with the preceding eaves of miner's helmet, and luminophor protrudes from described receiving alarm module downside.
Described accumulator cover the blocked hole that is provided with a rectangle, upper wall at blocked hole has fixed orifice, described power electrode terminal by two electrode columns of the upper wall inboard that is located at this blocked hole and above the described sensing transmitter module corresponding elastic electrode form, each electrode column all is connected with the electrode of accumulator by lead; The thickness of described sensing transmitter module is slightly less than the height of described blocked hole, at this screw corresponding with described fixed orifice is arranged above the sensing transmitter module housing, at the opposite side of housing removably ventilating cover is housed, and firedamp sensor is housed in it; In the lead link hole inwall corresponding groove between described electrode column and the accumulator.
One side of described sensing transmitter module is provided with voltage detecting hole and the adjustment hole corresponding with described alarm set point point of adjustment.
The utility model is installed in one independently in the housing with firedamp sensor and transmitter, be connected with battery cap by structure removably, and by the wireless radio transmission alerting signal, so just can be when alarm is calibrated at an easy rate firedamp sensor and transmitter housing be unloaded and send to calibration separately, no longer need miscellaneous part is together carried, greatly facilitate calibration.And visual alarm is more obvious.
