The principle of operation of the present invention will now be described as follows: the foot pad 14 is bound on the soles of labor insurance shoes of miners through spikes, then workers to be put down wear labor insurance shoes, work clothes, safety helmets and the like, the explosion-proof housing 3 is bound on the body (generally waist) through the binding mother belt 19 and the binding male belt 20, then the head lamp on the safety helmets is connected with the output interface 6 through a power line, then a start button on the explosion-proof housing 3 is connected, at the moment, one of the electric cores 4 can supply power for the head lamp on the safety helmets, and the miners can put down the miners;
when a miner walks, after the miner's feet are lifted, the spring 171 can prop up the V-shaped opening 15 of the foot pad 14, at this time, the space inside the elastic membrane sleeve 172 is increased, so that the pipe end of the air inlet pipe 173 can generate negative pressure suction through the air exhaust pipe 174, and external air can be sucked into the elastic membrane sleeve 172, when the miner's feet fall down, the spring 171 can be compressed under the gravity action of the miner, and the elastic membrane sleeve 172 can be compressed synchronously, under the compression action, air inside the elastic membrane sleeve 172 can be extruded from the L-shaped pipe 175, the extruded air can enter the air inlet cylinder 107 through the connecting hose 177, then air flows into the hollow cylinder 101 through the air inlet cylinder 107 and impacts the impeller 103, at this time, the impeller 103 starts to rotate under the action of the air flow, so that the shaft end of the micro-generator assembly 9 can be driven by the rotating rod 102, and the micro-generator assembly 9 starts to perform power generation work, and as the foot pad 14 can alternately supply air to the air inlet cylinder 107 in cooperation with the walking of the miner, and therefore, good power generation efficiency can be maintained when the miner walks;
the air flow impacting the impeller 103 enters the air outlet cylinder 108 and is discharged into the frame-shaped hood 112 through the air outlet pipe 111, then the air flow is discharged into the two sealing hoods 131 through the plurality of air holes 114, heat of the battery core 4 during operation is transferred to the heat conducting plate 113, and the air flow can take away the heat when flowing through the heat conducting plate 113 through the air holes 114, so that the heat dissipation and the temperature reduction of the battery core 4 can be assisted, and the heat accumulation in the explosion-proof housing 3 is prevented;
the air entering the air outlet cylinder 108 contacts with the tin oxide ceramic block 122, when the tin oxide ceramic block 122 contacts with the air, the air reacts with oxygen to form a tin oxide surface, the surface is in an equilibrium state, if hydrogen sulfide gas exists in the air, the hydrogen sulfide gas reacts with the tin oxide ceramic block 122 to cause charge transfer of the tin oxide ceramic block 122, the resistance of the tin oxide ceramic block 122 is reduced, the higher the concentration of the hydrogen sulfide is, the more the resistance of the tin oxide ceramic block 122 is reduced, so that a miner walks to a position with higher concentration of the hydrogen sulfide, the more the resistance of the tin oxide ceramic block 122 is reduced, at the moment, the resistance in a connecting loop of the tin oxide ceramic block 122 and the electromagnetic switch 123 is reduced, so that the electromagnetic switch 123 can be led to a larger current, the electromagnetic switch 123 can generate enough magnetism to absorb a self-moving contact, the connecting loop between the buzzer 124 and the electric core 4 can be switched on, the alarm 124 can be powered on to perform the alarm work, and the alarm work can be avoided when the worker is in a work area with excessive hydrogen sulfide, and the alarm work area can be prevented from being inhaled;
while the air discharged into the two sealing covers 131 enters the air storage box 132 through the circular tube 133, when the concentration of hydrogen sulfide is higher, the resistance in the connecting loop between the tin oxide ceramic block 122 and the normally open electromagnetic valve 135 is more reduced, at the moment, the current flowing into the normally open electromagnetic valve 135 is increased, so that the opening degree of the normally open electromagnetic valve 135 is smaller, and the current flowing into the normally open electromagnetic valve 135 is larger along with the increase of the concentration of hydrogen sulfide, so that the opening degree of the normally open electromagnetic valve 135 is smaller until the normally open electromagnetic valve 135 is closed, and after the opening degree of the normally open electromagnetic valve 135 is smaller, the air discharged through the exhaust tube 134 is slowed down, at the moment, the air pressure in the air storage box 132 is increased, and when the concentration of hydrogen sulfide continuously exceeds the standard, the air pressure in the air storage box 132 is continuously increased until under the action of the air pressure, the movable contact of the air pressure automatic switch 136 can be closed by back pressure, at the moment, the air pressure automatic switch 136 can be connected with a connecting loop between the voice prompt 137 and the electric core 4, the voice prompt 137 starts to perform voice prompt work, on one hand, the personnel can be reminded that the concentration of hydrogen sulfide is continuously overhigh and is quickly far away by changing the prompt mode, after the personnel leaves the area with higher concentration of hydrogen sulfide, the voice prompt 137 continuously works through the power-off delay relay 138 after the air pressure in the air storage box 132 is recovered, so that the personnel can keep enough safe distance, meanwhile, after the movable contact of the air pressure automatic switch 136 is closed, the 4G communication circuit board 71 can receive the electric signal of the air pressure automatic switch 136, at the moment, the 4G communication circuit board 71 can automatically remotely send alarm information to the coal mine management terminal to prevent the miners from forgetting to timely notify dangerous information to the terminal, the coal mine management terminal can notify other miners of evacuation information after receiving the alarm information;
