Abstract
A kind of electric shock preventive helmet with voice alarm function is made up of high-pressure electronic testing circuit and sound light alarming circuit, high-voltage detecting circuit is connected to form by antenna and MOS semiconductor field VF and transistor V1, sound light alarming circuit is by light emitting diode VL and transistor V2, V3 and loudspeaker BL and speech IC are connected to form, when having high-tension electricity near not feeling, the red light emitting diodes VL of this electric shock preventive helmet with voice alarm function does not work, loudspeaker BL also not sound, when having high-tension electricity near safety cap, VL lights, loudspeaker BL sends audio alert sound, the utility model can when near sensing, high-tension electricity exists, red light emitting diodes is lighted, loudspeaker can send simultaneously " has electricity dangerous, please don't be close " phonic warning sound, people are reminded to note, effectively prevent electric shock serious accident from occurring.
Description
Technical field
The utility model electronic technology field is a kind of Anti-electroshock safety helmet.
Background technology
A few days ago, along with urban development electric power and construction engineering get more and more, be unable to do without power supply everywhere, present stage has some play warning function safety means when getting an electric shock on the market, but most accident occurs in thought of people paralysis in a flash, when getting an electric shock in the position of human body, first electric current passes through human body significant points as passed right thoracic heart region, respiratory system and nervous centralis etc. are greatly dangerous, cause electric shock person to breathe once get an electric shock and stop cardioplegia to dead, the inevitable safety measure applied with shortage again, so one can closely but when not contacting, just play suggestion voice effect and can just become very necessary by portable device.
Summary of the invention
The utility model technical solution problem is open a kind of electric shock preventive helmet with voice alarm function, it can effectively allow the workpeople being operated in post avoid causing pernicious human casualty accident to occur, this utility model is made up of high-pressure electronic testing circuit and sound light alarming circuit, high-voltage detecting circuit is connected to form by antenna and MOS semiconductor field VF and transistor V1, sound light alarming circuit is connected to form by light emitting diode VL and transistor V2, V3 and loudspeaker BL and speech IC, and high-pressure electronic testing circuit is connected with sound light alarming circuit by V1; When having high-tension electricity near not feeling, the red light emitting diodes VL of this electric shock preventive helmet with voice alarm function does not work, loudspeaker BL also not sound, when having high-tension electricity near safety cap, antenna will receive the mains frequency number of 50Hz, and this signal is after the frequency-selective network frequency-selecting that resistor R3 and capacitor C2 etc. form, add to the grid of VF, after VF and V1 amplifies, make V2 saturation conduction, on the one hand VL is lighted; Triggering voice IC and V3 work on the other hand, loudspeaker BL sends audio alert sound.
Accompanying drawing illustrates:
Fig. 1 is electronic-circuit diagram of the present utility model.
Detailed description of the invention:
The concrete modus operandi of the utility model protection against electric shock voice safety cap is made up of high-pressure electronic testing circuit and sound light alarming circuit, high-voltage detecting circuit is connected to form by antenna and MOS semiconductor field VF and transistor V1, sound light alarming circuit is by light emitting diode VL and transistor V2, V3 and loudspeaker BL and speech IC are connected to form, when having high-tension electricity near not feeling, the red light emitting diodes VL of this electric shock preventive helmet with voice alarm function does not work, loudspeaker BL also not sound, when having high-tension electricity near safety cap, antenna will receive the mains frequency number of 50Hz, this signal is after the frequency-selective network frequency-selecting that resistor R3 and capacitor C2 etc. form, add to the grid of VF, after VF and V1 amplifies, make V2 saturation conduction, on the one hand VL is lighted, triggering voice IC and V3 work on the other hand, loudspeaker BL sends phonic warning sound, antenna can be connected on the inwall of external shell of safety helmet, regulator potentiometer RP, make antenna when the live wire near 220V power supply is about 0.5m or is far away apart from 10000V high-voltage line 2m, electric shock preventive helmet with voice alarm function can send sound and light alarm, sense red light emitting diodes when neighbouring high-tension electricity exists during work to light, loudspeaker can send simultaneously " has electricity dangerous, please don't be close " phonic warning sound, people are reminded to note, effectively prevent electric shock serious accident from occurring, this electric shock preventive helmet with voice alarm function structure is simple, easy to use, safe and reliable, effectively prevent the people of work to get an electric shock generation serious accident, produce serious consequence.
