Description

Emergent safety helmet
Technical field
The invention belongs to the improvement of safety helmet safeguard function, particularly relating to one can have with Emergency Oxygen Supply The emergent safety helmet of active defense function.
Background technology
Underground coal mine (and non-coal mine, underground engineering, workshop etc. must wear the field of safety helmet Institute) working space is narrow, bad environments.During normal production work, it is likely to burst accident, Produce toxic and harmful, jeopardize the life security of Field Force.And the safety prevention measure that mine is taked Mainly having two classes: one is compressed oxygen self-lifesaving device, two is air-pressed self-rescuer.Taught by production practices and accident Instruction proves, above two safeguard procedures all exist the biggest defect:
Compressed oxygen self-lifesaving device, can carry on the arm piggyback, it is also possible to be through on belt, must take with oneself on request Band.But its volume is big, weight big, can increase operating personnel's labor intensity, affect normal operating, typically All it is suspended from distance operating personnel 3~5m.After dangerous situation occurs suddenly, even if Field Force keeps Calm and operation is quite skilled, from take self-rescuer to open wear carry out autonomous respiration it is generally required to 1~ 2min, the most often has little time to wear self-rescuer, is just injured by toxic and harmful.
Air-pressed self-rescuer, is a kind of self-help apparatus being fixed on compressed air line, when running into dangerous situation, Personnel can open switch, and hole compressed air provides oxygen.Exist according to " preventing and treating coal and gas prominent regulation " Distance getting working face 25~40m at install, personnel from withdraw to opens air-pressed self-rescuer needs one section time Between, the purpose of quick emergency self-saving can not be reached.
Under present circumstances, seldom hear the case using compressed oxygen self-lifesaving device or air-pressed self-rescuer successfully to save oneself Example, it is simply that because not having enough saving oneself the movement response time.Even doing some training very often, wear special rescue The mine rescue team member of respiratory organ, the most once occurred to meet the case that burst accident comes to harm.
Utility model content
The purpose of this utility model is to solve from finding that dangerous situation is to having worn compressed oxygen self-lifesaving device or having entered pressure Wind self-rescuer carries out the time difference that process of saving oneself exists, it is provided that one can have active defense by emergency oxygen supply The emergent safety helmet of function.
The purpose of this utility model is achieved in that
A kind of emergent safety helmet, including cap shell, hat lining,
Described compressed oxygen storage device is provided with the draw ring switch for opening compressed oxygen storage device valve;
Described cap shell bottom is provided with collapsible Isolated mask, and described Isolated mask is in the on-state in cylinder Shape, the part of Isolated mask correspondence human body face uses transparent plastic to make, and the lower limb of Isolated mask sets Put rubber band, be used for tightening up Isolated mask lower end, make face shield be coated with human body head.
The lower limb of Isolated mask is connected with the draw ring switch of compressed oxygen storage device by stay cord, forms connection Dynamic structure, while opening face shield, can open draw ring switch simultaneously.
In order to effectively utilize the cabochon space between cap shell, hat lining, further, described compressed oxygen storage Cryopreservation device is in the dome shape corresponding with cap shell, hat lining shape, and compressed oxygen storage device is fixed on cap roof portion And between hat lining top.
In order to ensure the anti-seismic performance of compressed oxygen storage device, it is possible to allow compressed oxygen storage device slowly release Putting oxygen, further, described compressed oxygen storage device is flexible air-bag.Flexible air-bag can make oxygen Relatively slowly release, reach to ensure respiration, the most do not make face shield too expand and cause oxygen leakage Purpose.
In order to ensure the intensity of compressed oxygen storage device, further, described compressed oxygen storage device uses Butyl rubber makes.
Further, the volume of described compressed oxygen storage device is 0.3L.As oxygenation air pressure 0.3Mp Time, oxygen scale about 0.9L.Through test, it is available for people and breathes no less than 3min.(also can suitably increase pressure Power, increases amount of oxygen, and the pressure of bicycle tube air pressure and mining compressed air is typically at 0.8Mp)
In order to ensure the fire protecting performance of compressed oxygen storage device, further, described Isolated mask uses multiple Close aluminium foil flameproof fabric to make.
Further, described Isolated mask open a length of 300mm.Make the rubber of Isolated mask lower end Muscle part be enough between neck be in close contact.
In order under normal conditions the Isolated mask of folded state effectively be positioned, further, described isolation face The fixing end of cover is fixed on the medial surface of cap shell, and the free end of Isolated mask is positioned to be provided with below hat lining Cap hoop.
For the ease of quickly opening Isolated mask under emergency condition, further, described Isolated mask lower end The position of corresponding human body ear is provided with drawstring.
Further, described drawstring sews on rubber band.
Owing to have employed technique scheme, this utility model has the advantages that
The present invention uses easy mechanical system, solves from finding that dangerous situation is to having worn compressed oxygen self-lifesaving device Or entrance air-pressed self-rescuer carries out the process of saving oneself and there is the emergency oxygen supply problem of time difference, add safety helmet Active defense function, has quick feature with low cost, easy to maintenance, simple to operate, it is possible to significantly Degree raising is saved oneself chance of success, effectively protection underground operators life security.This utility model is also suitable In the space of the relative closures such as other mines, workshop, basement, operation is by toxic and harmful or cigarette Carry out emergency self-saving during dirt invasion and attack, be with a wide range of applications.
This utility model is strictly observing GB2811-2007 specification, does not change safety helmet modular construction, skill On the premise of the indexs such as art requirement and fundamental technology performance, set up oxygen-storing device and isolating and protecting face shield. Volume is little, lightweight, will not increase operating personnel's labor intensity, not affect normal operating, if meeting with suddenly Chance toxic and harmful attack, it is possible to quickly leave behind face shield and open oxygen supply switch, it is ensured that personnel 3 minutes Above breathing time, during for using isolating compressed oxygen self-lifesaving device or air-pressed self-rescuer to win preciousness nearby Between.
Accompanying drawing explanation
