Tunnel respiratory protection device with detection alarm prompt

Abstract

The invention discloses a tunnel respiratory protection device with the detection and alarm prompt. The tunnel respiratory protection device comprises a cylindrical mounting block and a first circular groove in the surface of the rear side of the cylindrical mounting block. A respiratory mechanism is arranged in the first circular groove. A fixing mechanism is arranged on the side surface of the cylindrical mounting block. An alarm detection prompting mechanism is arranged on the side surface of the cylindrical mounting block. A controller is arranged on the side surface of the cylindrical mounting block. The input end of the controller is electrically connected with a first arc-shaped electronically-controlled orifice plate, an oxygen concentration detection sensor, an infrasonic wave detection sensor, a gas concentration detection sensor and a temperature sensor. The output end of the controller is electrically connected with alarming lamps. The tunnel respiratory protection device has the beneficial effects of being simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of detection and warning respiratory protection, in particular to a tunnel respiratory protection device with detection and alarm prompts. Background technique [0002] With the continuous development of social science and technology, people's lives are constantly improving, there are more private cars, and the roads are congested. Some people are often late for work. In order to slow down this situation, large cities will build subways or light rails to relieve urban Due to the changeable underground conditions and insufficient oxygen, there may be poisonous gas, so people will choose to wear gas masks, but ordinary gas masks only have anti-virus functions, use lighting tools, The more tools there are, the more inconvenient it is to carry. Therefore, in order to ensure people's safety and reduce the number of tools to be carried, it is necessary to design such a device. Contents of the invention [0003] The purpo...
