Abstract
The utility model provides a positive pressure air breathing apparatus and belongs to the technical field of fire controlling and fire extinguishing appliance. The positive pressure air breathing apparatus comprises an air supply pipe connected with a compressed air bottle and an others-rescue port on the air supply pipe, an early warning signal sounder is arranged on the position of the others-rescue port, and a hand switch is arranged between the others-rescue port and the early warning signal sounder. According to the positive pressure air breathing apparatus, the early warning signal sounder is arranged on the position of the others-rescue port, and the problems that information transferring, communication and the like between commanders and combatants are influenced seriously when firemen wear a positive pressure air breathing apparatus in the prior art are solved. On the premise of not influencing normal use of the positive pressure air breathing apparatus, the positive pressure air breathing apparatus can remind the firemen to leave a site quickly and achieve an early warning purpose. Thus, the positive pressure air breathing apparatus has the advantages of being good in early warning effect, simple, practical, convenient to operate, low in cost, convenient to disassemble and assemble, stable and reliable.
Description
Technical field
The utility model belongs to the fire-fighting fire-extinguishing equipment technical field, specifically a kind of positive-pressure air respirator.
Background technology
On-the-spot at the fire fighting and rescue of various complexity, the fireman is in danger constantly, caves in, the secondary disasters such as poison gas, dense smoke occur at any time.At present, the fireman often adopts at the fire fighting and rescue scene and wears positive-pressure air respirator and protect own life, prevents the events such as poisoning.But the positive-pressure air respirator of wearing at present, information transmission, communication etc. all are subject to having a strong impact on of face shield, respiratory air flow and on-the-spot noisy environment between commander and the fighter, can not transmit in time, rapidly imminent danger signal, cause personnel casualty accidents to happen occasionally.
The utility model content
Technical problem to be solved in the utility model be the shortcoming that information transmission between commander and the fighter, communication etc. are all had a strong impact on when overcoming fireman of the prior art and wearing positive-pressure air respirator and provide that a kind of early warning is effective, simple and practical, easy to operate, with low cost, easy accessibility, reliable and stable positive-pressure air respirator.
Adopt following technical scheme for solving technical problem of the present utility model:
A kind of positive-pressure air respirator comprises that air supply pipe that compressed air bottle connects, on the air supply pipe he rescue interface, described he rescue interface the early warning signal acoustical generator be set, described he rescue a manual switch be set between interface and the early warning signal acoustical generator.
Described hand switch is spiral manual switch.
The structure that the utility model adopts is that he of the positive-pressure air respirator generally worn the rescue site fireman rescues interface the early warning signal acoustical generator is installed, the problem that information transmission between commander and the fighter, communication etc. are all had a strong impact on when having solved the positive-pressure air respirator that fireman of the prior art wears, so that in the situation that do not affect the normal use of positive-pressure air respirator, in time remind the fireman to withdraw fast the scene, reach the early warning purpose.Be that a kind of early warning is effective, simple and practical, easy to operate, with low cost, easy accessibility, reliable and stable positive-pressure air respirator.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: the 1-Pressure gauge; 2-compressed air bottle, 3-backboard, 4-face shield; 5-handwheel air valve switch; The 6-air supply pipe; He rescues interface 7-; The 8-hand switch; 9-early warning signal acoustical generator.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of positive-pressure air respirator comprises Pressure gauge 1, compressed air bottle 2, back bracket 3, face shield 4, handwheel air valve switch 5, air supply pipe 6, he rescues interface 7, hand switch 8, early warning signal acoustical generator 9.On compressed air bottle 2 connection air supply pipes 6, the air supply pipe 6 he is installed and rescues interface 7, air supply pipe 6 is connected with face shield 4, is used for normal air feed and uses.Rescue interface 7 places at him an early warning signal acoustical generator 9 is installed.Rescue installation one screw type hand switch 8 between interface 7 and the early warning signal acoustical generator 9 at him, be used for the unlatching of the release of control air-flow and early warning signal.When the fireman bore the utility model work at fire extinguishing rescue scene, hand switch 8 was in " closure " state, and compressed air bottle 2 is normally to face shield 4 air feed.If when predicting dangerous generation, open fast hand switch 8, part air-flow is still normally to face shield 4 air feed, another part air-flow at compressed air bottle 2 compressed airs under pressure, flow to early warning signal acoustical generator 9 by hand switch 8, the energy that utilizes air-flow to discharge to the external world shakes so that early warning signal acoustical generator 9 sends chimes of doom, in time reminds the fireman to withdraw fast the scene.
Claims (2)
1. positive-pressure air respirator, comprise that air supply pipe that compressed air bottle connects, on the air supply pipe he rescue interface, it is characterized in that: described he rescue interface (7) and locate to arrange early warning signal acoustical generator (9), described he rescue a manual switch (8) be set between interface (7) and the early warning signal acoustical generator (9).
