[0027] Working principle of the present invention: When the present invention is used, it is worn on the head of the staff through the chin strap 3, and the chin strap 3 is a conventional chin strap. The present application integrates a near-electricity alarm 13 on the safety helmet, which can detect whether the equipment has surface electricity or leakage, and emits a continuous alarm sound to remind the staff, so that the staff has psychological expectations. Since there are places with poor gas fluidity in the power station operating environment, the content of harmful gases is high. If they enter directly, it will cause harm to the body of the staff. When the harmful gas content is detected to be high, the staff will be reminded through a buzzer. The shell 1 of the present application is provided with a fireproof insulating sleeve 5 inside, which can play a good fireproof and heat-insulating role. The lining cloth 24 is provided to improve comfort. Although the setting of the fireproof insulating sleeve can improve the fireproof and electrical performance, it will make the helmet more stuffy.

During live working, sometimes debris may fall from the upper side. When the debris falls and hits the safety helmet, the impact sensor 9 will be triggered. The impact sensor 9 will transmit the signal to the control main board 10 and control the air pump 21 to inflate the buffer air bag 6, providing additional buffer protection and improving the safety protection ability of the operator. The communication module 8 is an intercom device that enables communication between the operator and the outside world. The lighting module 7 is used to illuminate the work. The outer side of the locking wheel is provided with evenly distributed card slots. By pulling out and plugging the plug block 30, the plug block 30 is separated from the card slot, and the lighting lamp 27 is rotated relative to the lamp holder 26, so that the lighting angle can be adjusted.
