Abstract
The utility model relates to a pocket coal gas sound and light alarm which is used under the ground in a coal mine or in the kitchen room and the bathroom of families, comprising a shell body, a power supply and a loudspeaker. The power supply is connected with the input terminal of a power supply of an electronic control device with a gas sensing probe; moreover, the output terminal of the electronic control device is connected with the loudspeaker and a light-emitting diode. An electronic integrated block is used in a circuit. The utility model has the advantages of simple structure, few elements, compactness, low cost, convenient installation and portability. The pocket coal gas sound and light alarm can be arranged on a miner's lamp to form a miner's lamp with a sound and light alarm function for gas. The pocket coal gas sound and light alarm can also be connected with the button of a door bell to perform the functions of a sound and light door bell and a sound and light alarm.
Description
The utility model relates to and a kind ofly is used under the coal mine or the gas leak detector in family's kitchen and bathroom, particularly a kind of pocket coal gas audible-visual annunciator.
In the prior art, multiple gas leak detector is arranged, mostly complex circuit, element is many, volume is big and cost is high, be not easy to install and carry.
The purpose of this utility model is to provide a kind of pocket-size coal gas audible-visual annunciator, is convenient to install and carry.
In order to achieve the above object, the utility model adopts following technical proposals: the same housing, power supply and the loudspeaker of including with prior art of the utility model.It is characterized in that power supply connects a power input that has the electronic-controlled installation of gas-sensing probe, and the output terminal of electronic-controlled installation connects loudspeaker and light emitting diode.During use, when gas-sensing probe sensed gas concentration greater than setting concentration, this alarm just sent sound and light alarm.
The power supply of this alarm can be 4 volts of direct supplys, loudspeaker is a hummer, the electronic-controlled installation circuit structure is: 4 volts of direct supplys connect one by gas-sensing probe, four electronic control circuits that resistance, KD-9562B type music alarm electronic integration block, triode and telefault are formed, and the output terminal of this electronic control circuit connects light emitting diode and hummer.The power supply of this alarm also can be that 220 volts of AC power are through 4 volts of direct supplys of a power circuit output.This power circuit is made of transformer, bridge rectifier, four electric capacity and W7805 type " three ends " voltage stabilizer.
The utility model has conspicuous advantage compared with prior art: the utility model circuit structure is simple, and element is few, especially adopts electronic integration block, and volume is greatly reduced, and cost is low, is convenient to install and carry, and has sound and light of alarm.
The explanation of accompanying drawing drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the circuit theory diagrams of an embodiment of the utility model.
Fig. 3 is that the utility model is installed on the structural representation on the mine lamp.
Fig. 4 is the circuit theory diagrams of another embodiment of the utility model.
An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, this pocket coal gas audible-visual annunciator includes housing 1, power supply 5 and loudspeaker 3, power supply 5 connects a power input that has the electronic-controlled installation 2 of gas-sensing probe 4, and the output terminal of electronic-controlled installation 2 connects loudspeaker 3 and light emitting diode D.Power supply 5 is 4 volts of direct supplys, and loudspeaker 3 is a hummer.Electronic-controlled installation 2 circuit structures are: 4 volts of direct supplys 5 connect one by gas-sensing probe 4, four electronic control circuits that resistance R 1, R2, R3, R4, KD-9562B type music alarm electronic integration block, triode G and telefault L form, the output terminal connection light emitting diode D and the hummer 3 of electronic control circuit.Its principle of work is: by the setting concentration of resistance R 1 setting gas-sensing probe 4 sensing coal gas, when gas-sensing probe 4 senses gas concentration above setting concentration, with its signal input KD-9562B electronic integration block, the output terminal OUT outputting music alerting signal of KD-9562B electronic integration block, amplify through triode G, starting hummer 3 and light emitting diode D send sound and light alarm.Power supply 5 also can connect a mine lamp 6, for mine lamp 6 provides power supply, and on the output line of power supply 5 K switch is housed, then as shown in Figure 3, this pocket coal gas audible-visual annunciator 7 is installed on the mine lamp 6, provides 4 volts of direct supplys, constitute by " gas sound and light alarm mine lamp " by storage battery 5.
Another embodiment of the present utility model is: referring to Fig. 4, power supply 5 is that 220 volts of AC power are exported 4 volts of direct supplys through a power circuit, and this power circuit is made of transformer B, bridge rectifier T, four capacitor C 1, C2, C3, C4 and W7805 types " three ends " voltage stabilizer.Electronic-controlled installation 2 circuit structures are: 4 volts of direct supplys connect one by gas-sensing probe 4, five electronic control circuits that resistance R 1, R2, R3, R4, R5, KD-9562B type music alarm electronic integration block, triode G and telefault L form, the output terminal connection light emitting diode D and the hummer 3 of electronic control circuit; On the connection line of power supply 5 and electronic control circuit K switch is arranged.Its principle of work is same as the previously described embodiments.When K switch during as bell button, then constitute " multifunction alarm device ", it had both played the effect of acousto-optic doorbell, also played the effect of coal gas audible-visual annunciator simultaneously.
