Mine gas detection safety helmet and detection method thereof

Abstract

The invention discloses a mine gas detection safety helmet and a detection method thereof, and relates to the technical field of detection equipment. The helmet comprises a safety helmet body and a controlling box, a groove is formed in the circumferential surface of the safety helmet, a suction mouth is fixed to the surface of the groove, an airbag is fixed to the inner surface of the safety helmet, one end of the suction mouth is connected with the airbag, rotary shafts are symmetrically fixed to the circumferential surface of the safety helmet, a mask is rotatably connected with the circumferential surfaces of rotary shafts, the circumferential surface of the safety helmet is fixedly connected with the control box, a probe is fixed to one surface of the control box, and an AD converted,a digital processor, an alarming device, a GPS module, a wireless communication module, a power supply, a gas sensor and a DA converter are arranged in the control box. According to the safety helmet, gas detection and the safety helmet are effectively combined, hands of people are liberated to flexibly deal with various kinds of emergency situations, spare oxygen is preset in the airbag, and when evacuation is conducted, the hauling of toxic gas can be prevented to ensure the life security of construction workers.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, in particular to a safety helmet for mining gas detection. Background technique [0002] Harmful gases in mines include carbon monoxide, gas, hydrogen sulfide, nitrogen dioxide, sulfur dioxide, ammonia, hydrogen, etc. These flammable, explosive, and toxic gases make underground operations dangerous, and underground gas safety detection is essential. [0003] At present, the existing gas detection method is that construction workers wear safety helmets on their heads and hold gas detectors. When evacuating, explosive, or toxic gas, the specific location cannot be known; while evacuating the mine, the detection results must be notified to the ground, which is extremely time-consuming, and while evacuating, they will breathe toxic gas, which greatly threatens the safety of construction workers. life safety.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a mining gas detection safety helmet, which solves the problem of being unable to flexibly respond to various emergencies by setting a control box on the safety helmet; automatically transmits data to the ground terminal server through the GPS module and wireless communication equipment. The position signal and detection result signal solve the problem that the ground personnel cannot know the specific location of the construction personnel and need to notify the ground personnel while evacuating; by breathing the spare oxygen in the airbag, the problem of breathing toxic gas while evacuating is solved
