Protective cover for rocket propellant operation

Abstract

The invention belongs to the field of wearable protective devices, and in particular relates to a protective cover for rocket propellant operation, which includes a cover body, a fixing device, a poison filter assembly and a breathing assembly. There is a connecting groove on the top, a connecting ring is integrally formed at the bottom of the inspection window, an airbag ring is fixedly connected to the inner side of the ring seat, an inflatable head is provided at the bottom of the airbag ring, and a clearing assembly is fixedly connected to the ring seat, and the clearing assembly includes two pieces of arc Two arc-shaped clearing plates are respectively located on the inner and outer sides of the inspection window. The fixing device includes a jacket. The jacket includes a shoulder strap and a chest strap. The shoulder strap and the chest strap are fixedly connected. The ring seat and the shoulder strap With sliding connection, the front side of the shoulder strap is fixedly connected with a support bar. It is used to solve the problems in the prior art that the weight of the protective mask is borne by the head of the staff, which is extremely prone to fatigue, and the staff's vision is narrow, and the inspection window is fogged, incomplete, scratched, etc., which affect the staff's sight.

Description

technical field [0001] The invention belongs to the field of wearable protective devices, in particular to a protective cover for rocket propellant operation. Background technique [0002] At present, the liquid rocket propellants used in my country are mainly nitro oxidants (27S nitric acid, dinitrogen tetroxide) and hydrazine fuels (unsymmetrical dimethylhydrazine, methylhydrazine and anhydrous hydrazine). Hydrazine-based fuels and nitro-oxidants have low boiling points, are volatile, and have strong corrosiveness and adsorption penetration. Therefore, when working with liquid propellants, in order to prevent poisoning, the staff need to use corresponding personal safety protective equipment. Personal protective equipment is divided into respiratory protective equipment and skin protective equipment, as well as protective masks and protective clothing. [0003] However, when the staff wore protective masks for propellant operations, they found the following problems: ...
