Vehicle driver protecting method in toxic harmful gas environment

Abstract

The invention provides a vehicle driver protecting method in a toxic harmful gas environment. The vehicle driver protecting method comprises a compartment, a driving cab, a helmet, a pipe, a switch valve and a chemical protective clothing, wherein the helmet, the pipe and the switch valve are arranged in the driving cab; the switch valve can control the compartment to supply gas to the helmet through the pipe; in a normal atmosphere environment, the switch valve is closed, and a driver does not wear the helmet, and relies on air in the normal atmosphere environment to breathe; and a toxic gasfiltrating and ventilating device in the compartment is opened, so that stable positive pressure is formed in the compartment, the switch valve is opened, the driver wears the helmet, positive pressure gas in the compartment of the vehicle enters the helmet to form the positive pressure in the helmet and enables the driver to breathe, and the situation that the harmful gas enters the helmet can also be avoided. Through the adoption of the vehicle driver protecting method disclosed by the invention, the problem that stable positive pressure protection cannot be formed in a driving cab of a conventional vehicle is solved, and the situation that the driver wearing a cumbersome pneumatic breathing machine enters the toxic harmful gas environment is avoided.

Description

technical field [0001] The invention relates to a protection method, in particular to a protection method for a vehicle driver in a toxic and harmful gas environment. Background technique [0002] Existing detection and rescue vehicles with positive pressure protection capabilities are all modified on the basis of ordinary vehicles, but the cabs of ordinary vehicles cannot be refitted with airtightness. Clothes. In this way, the driver needs to wear a mask to start the ventilator, and the mask of the pneumatic ventilator needs to be in close contact with the driver, which brings discomfort to the driver, is affected by the size of the oxygen cylinder, and cannot work in a toxic and harmful gas area for a long time. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a method for protecting the driver of a vehicle in a toxic and harmful gas environment, which is applied to a detection and rescue vehic...
