Abstract

The utility model discloses a novel mining self-rescuer with a silica gel half mask. On a basis of not changing the basic structures of various conventional mining self-rescuers, a special silica gel half mask and a silica gel head tape are adopted instead of nose clip sets and mouth tool sets in various conventional mining self-rescuers. By using the novel mining self-rescuer, people entering wells can breathe comfortably and smoothly with small resistance and higher safety and reliability while wearing the mining self-rescuer in case of escape from danger, and the situation of death of people by inhaling toxic and harmful gases due to forget of wearing of nose clips or falling of nose clip sets during escaping is avoided.

Description

A kind of new type mining self-rescuer with silica gel half face shield

(1) technical field

The present invention relates to the mining self-rescuer using when the colliery personnel of going into the well must carry in order to emergency escape.It is a kind of new type mining self-rescuer with silica gel half face shield.

(2) background technology

Self-rescuer is help device, the patron saint of coal miner, and while there are the serious disasters and accidents such as gas explosion under coal mine, emergency escape personnel wear the self-rescuer that can play respiratory protection effect, just can flee from disaster area, save life from damage.China < < safety regulations in coal mine > > regulation: enter well personnel and must carry self-rescuer; Thereby China's overwhelming majority colliery has all been equipped with mining self-rescuer for entering well miner.Although various types of mining self-rescuers can play the effect of emergency escape respiratory protection substantially now, the impact due to factors such as parts design manufacture and unreasonable structure, also exists a little unsafe factors and hidden danger.Mouth tool group, nose clip group are general vitals in existing all kinds of mining self-rescuer, when personnel's emergency escape is worn self-rescuer, must catch in its mouth bite-block in tight mouthful tool group, by nose clip group, clamp nose, the object of doing is like this, only permit with the clean air in mouth respiratory self-rescuer, and disapprove with the toxic and harmful in respiratory nasal surrounding environment.Nose clip group clamps nose can make nose pain feel bad, and nose clip group can be in the road of escape because jolting, the factor such as perspiration comes off, the nose clip group consequence causing that comes off is well imagined, for many years, each colliery of China came off and has breathed toxic and harmful and cause dead case because forgetting to wear nose clip or nose clip group with regard to once there are many cases emergency escape personnel.The hidden danger that nose clip group exists is the fact that the colliery industry relevant personnel know altogether.Parts in existing all kinds of mining self-rescuer are more, structure is comparatively complicated, under the prerequisite that does not change primary structure, with a kind of novel parts, replace mouthful tool group, the nose clip group in self-rescuer, are the directions of relevant personnel's innovation.

(3) patent of invention content

The object of patent of the present invention, with a kind of silica gel half face shield of specializing in, silica gel headband, replace mouth tool group, nose clip group in existing all types of mining self-rescuer, thereby make all types of mining self-rescuers wear no pain while using, safety and comfort, more safe and reliable more.

The object of patent of the present invention realizes in the following way:

A kind of new type mining self-rescuer with silica gel half face shield.It is on the basis of existing all kinds of mining self-rescuer technology, does not change the basic structure of existing all kinds of mining self-rescuers, only with the silica gel half face shield of specializing in, silica gel headband, replaces original mouthful of tool group, nose clip group parts, and forms new type mining self-rescuer.About half face shield, there is specific technical term.GB2890-2009 < < respiratory protection self-absorbing filtering type gas defence mask > > is " half face shield is closely sealed with face; can hide mouth and nose, or covers the face shield of mouth, nose and lower jaw " to the definition of half face shield.Although its definition only has in short, because material is different, different to cause its external form be diversified to purposes.Half face shield is generally all for reaching the special research and development design of a certain object.We innovate the silica gel half face shield of research and development specially, silica gel headband with eliminated a mouthful tool group, the mining self-rescuer critical piece of nose clip group combines and the new type mining self-rescuer that forms, it is characterized in that: the silica gel half face shield place corresponding with people's oral area has an oval-shaped hole, the area of slotted eye is equally large with the front face area that is inlaid with suction expiration valve seat on self-rescuer air bag, the circumferential perimeter of slotted eye has silica gel shirt rim, after the slotted eye shirt rim of silica gel half face shield and the side colligation of inhaling expiration valve seat is fastening with nylon cable tie or metal larynx hoop, the connecting portion of silica gel headband is fastened on to the side of inhaling expiration valve seat, again according to original assembly program assembling, new type mining self-rescuer has just been assembled successfully.When entering, well personnel are in danger to wear self-rescuer respiratory protection when escape; open and throw away the upper cover of self-rescuer, then pick up silica gel Head band cover on head, meanwhile pick up half face shield and be enclosed within on mouth and nose; follow procedure is opened miscellaneous part again, just can be drawn onto clean air and escape danger and escaped.

Patent of the present invention has following actively useful effect

When colliery enters that well personnel are in danger wears the escape of this new type mining self-rescuer, silica gel headband can guarantee that self-rescuer is suspended on shirtfront securely, silica gel half face shield can be closely mutually closely sealed with face, having eliminated the former nose clip group leader time clamps the misery of nose, has more avoided forgetting to wear with cause that nose clip or nose clip group come off and the situation that causes personnel to suck toxic and harmful death occurs, and entering well emergency escape personnel, to wear new type mining self-rescuer respiratory resistance little more comfortable unobstructed, more safe and reliable.

(4) accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 1 is existing mining self-rescuer generalized section

Fig. 2 is silica gel special half face shield

Fig. 3 is silica gel special headband

Fig. 4 is new type mining self-rescuer generalized section, is also specific embodiment of the invention figure.

(5) specific embodiment

6 mouthfuls of tool groups of number in the figure 1 oxygen supply group 2 air bag group 3O type circle 4 lower casing group 5 nose clip groups 7 are inhaled expiration valve seat 8 silica gel half face shield 9 silica gel half face shield shirt rim 10 silica gel headbands

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, patent of the present invention is a kind of new type mining self-rescuer with silica gel half face shield.It is in the situation that the basic structure of existing all types of mining self-rescuers and main parts size as oxygen supply group 1, air bag group 2, O type circle 3, lower casing group 4, inhale expiration valve seat 7 and do not change, only eliminate nose clip group 5, mouthful tool group 6, and replace with silica gel half face shield 8, silica gel headband 10.Also when manufacturing mining self-rescuer product, nose clip group 5 and mouthful tool group 6 have no longer been assembled; But silica gel half face shield shirt rim 9 use nylon cable ties or the colligation of metal larynx hoop are fastened on to the side of inhaling expiration valve seat 7; Then silica gel headband 10 is also fastened on to the side of inhaling expiration valve seat 7, can forms new type mining self-rescuer.
