Description
Technical Field
The invention belongs to the technical field of miner safety, and particularly relates to an oxygen supply safety helmet for a plateau mine.
Background
With the aggravation of the contradiction between supply and demand of mineral resources and the deep implementation of the western strategy for development, the center of gravity of resource exploitation and utilization in China is gradually shifting to the western plateau area. Along with the rise of altitude, the air becomes thin, and atmospheric pressure reduces gradually, and the oxygen partial pressure in the air also reduces gradually, and this leads to the work environment in plateau mine pit to become more abominable, and lower oxygen partial pressure makes the miner often appear respiratory disease and leads to the psychological burden aggravation, has seriously influenced going on of mineral resources exploitation efficiency and safety in production. The research on the portable safety helmet with the oxygen supply function has important significance for the safety and health protection of the miners in the plateau mine.
Safety helmets are used as necessary safety protection devices for miners, and most safety helmets in the market at present only have basic functions of collision prevention, illumination and the like. Therefore, in order to adapt to the low-pressure oxygen-poor environment in the plateau underground, the invention provides the safety helmet with the oxygen supply function, which is suitable for the plateau underground mine, provides safety protection for the plateau underground miners and simultaneously ensures the oxygen requirement of the workers.
Disclosure of Invention
In order to ensure that the plateau underground miners can obtain basic safety protection and ensure the oxygen requirement, the invention provides an oxygen supply safety helmet for plateau mines, which has the technical scheme that:
the utility model provides an oxygen suppliment safety helmet for plateau mine, includes the cap body and oxygen system, the auxiliary device of the cap body includes brim of a hat, face guard fixer, light and cheek area down, oxygen system includes oxygen cylinder, atmospheric pressure sensor, ball valve, gaseous capsule, oxygen pipe, respirator and exhaust duct for carry out the oxygen suppliment to plateau mine workman.
The face guard fixer is used for fixing respirator, has the function of control oxygen system switch simultaneously, will respirator card when on the face guard fixer, the face guard fixer will the pipe of breathing in pin, oxygen system stop the oxygen suppliment promptly, when the workman need the oxygen suppliment in the pit, take respirator from the face guard fixer down, oxygen system can begin work.
The oxygen cylinder is filled with high-pressure oxygen for providing an oxygen source for plateau mine workers, and the filling amount of the oxygen in the oxygen cylinder can be determined by the expected time of the workers working underground.
The atmospheric pressure sensor is used for monitoring the atmospheric pressure value at the altitude of the plateau mine worker, and the size of the ball valve switch is controlled according to the detected atmospheric pressure value, so that sufficient oxygen supply is guaranteed, and meanwhile, oxygen waste is prevented.
The gas capsule has the function of storing oxygen, so that the continuity is realized at the initial stage of oxygen supply.
The breathing mask is used for workers to wear oxygen inhalation.
The oxygen conduit is used for connecting the breathing mask and the oxygen bottle, has the characteristics of easy bending and difficult leakage, and ensures that oxygen in the oxygen bottle smoothly enters the breathing mask.
The exhaust duct is used for exhausting gas such as carbon dioxide and the like out of the oxygen supply system when a worker exhales.
The invention has the beneficial effects that:
(1) the safety helmet can provide basic safety protection and illumination for plateau underground miners and simultaneously ensure the oxygen requirement of the miners;
(2) the safety helmet can be used at any time, so that oxygen supply is ensured, and oxygen waste is avoided;
(3) the safety helmet is light in weight and convenient to wear.
