Description
Technical field
The utility model belongs to fire-fighting equipment technical field, is specifically related to a kind of fire emergency signalling means.
Background technology
Fire residence is on-the-spot, and because burning can produce a large amount of smog, people's visibility under smoky environment is very low, causes escape difficulty.Meanwhile, when fiery residence occurs, because environment is very noisy, establishment officer or fireman are sent and are covered by brouhaha by the oral instruction sent, and are difficult to the normally orderly masses that organize and escape, thus make the state of affairs uncontrollable.Existing signalling means, is generally only applicable to the fire-fighting team of specialty, is generally electronic type, and be not suitable for more special scene of fire and use, such as, when needing fire-proof and explosion-proof, the signalling means of electronic type then can not use; And the signalling means of this kind of electronic type, for the ease of carrying, therefore power is less, and cause the sound that sends very little, in noisy scene of fire, volume does not reach requirement yet.
Utility model content
The purpose of this utility model is: for Problems existing in existing electronic type signalling means, provide a kind of fire emergency signalling means, adopts mechanical mechanism, gives great volume, applied widely.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of fire emergency signalling means, comprise air respiratorresuscitator gas cylinder, air source distributor, face shield, by compressing switch and steam whistle, the gas outlet of air respiratorresuscitator gas cylinder is connected with air source distributor by connecting hose, air source distributor, to be connected with steam whistle by compressing switch with face shield, be connected by compressing switch respectively by connecting hose.
Preferably, described comprises valve body, valve rod, spool, fixing handle and pressure handle by compressing switch, valve body is provided with the intake channel and air outlet passage that are interconnected, spool is arranged between intake channel and air outlet passage, and be connected with valve rod, fixing being fixed on valve body, pressure handle is connected axle with fixing, during pressure handle extruding valve rod, moved to the position being communicated with described intake channel and air outlet passage by valve rod band movable valve plug; Also be provided with returning spring between spool and valve body, when unclamping pressure handle, returning spring band movable valve plug moves to the position blocking described intake channel and air outlet passage; Intake channel connects with the connecting hose being connected air source distributor; Air outlet passage connects with the connection hard tube being connected steam whistle.
Preferably, the gas outlet of air respiratorresuscitator gas cylinder is also provided with gas cylinder main valve.
Preferably, on compressing switch, also Pressure gauge is connected with.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
A kind of fire emergency signalling means of the present utility model, utilize air respiratorresuscitator to provide source of the gas, drive the steam whistle of large volume, sound is loud and clear, also can send control instruction clearly when environment is noisy, guides masses suffering from disaster's safe escape; Simultaneously, between the source of the gas that steam whistle and air respiratorresuscitator provide, be provided with mechanical by compressing switch, by encoding to the length of sound, and utilize pressing switch control rule steam whistle to send corresponding sound instruction, fire-fighting team is made to carry out various operation in an orderly manner, the safe escape that masses suffering from disaster can be orderly.

Detailed description of the invention
With reference to Fig. 1, a kind of fire emergency signalling means of the present utility model, comprise air respiratorresuscitator gas cylinder 1, air source distributor 2, face shield 3, by 6 and the steam whistle 7 of compressing switch, the gas outlet of air respiratorresuscitator gas cylinder 1 is provided with gas cylinder main valve 8, gas cylinder main valve 8 is connected with air source distributor 2 by connecting hose 4, air source distributor 2 respectively by connecting hose 4 and face shield 3,6 to be connected by compressing switch, 6 to be connected with steam whistle 7 by compressing switch.Pressure gauge 5 is also connected with by compressing switch on 6.Air respiratorresuscitator gas cylinder 1 is also provided with strap component (not shown), can air respiratorresuscitator gas cylinder 1 is carried on the back at back by strap component, be easy to carry.
With reference to Fig. 2,6 valve body 64, valve rod 66, spool 63, fixing 62 and pressure handle 61 is comprised by compressing switch, valve body 64 is provided with the intake channel 68 and air outlet passage 65 that are interconnected, spool 63 is arranged between intake channel 68 and air outlet passage 65, and be connected with valve rod 66, fix and be fixed on 62 on valve body 64, pressure handle 61 is connected 62 axles with fixing, when pressure handle 61 extrudes valve rod 66, moved to the position being communicated with described intake channel 68 and air outlet passage 65 with movable valve plug 63 by valve rod 66; Also be provided with returning spring 67 between spool 63 and valve body 64, when unclamping pressure handle 61, returning spring 67 moves to the position blocking described intake channel 68 and air outlet passage 65 with movable valve plug 63.Intake channel 68 connects with the connecting hose 4 being connected air source distributor 2; Air outlet passage 65 connects with the connection hard tube 9 being connected steam whistle 7.
When opening gas cylinder main valve 8, the high-pressure air source in gas cylinder flows to air source distributor 2, divides to face shield 3 by air source distributor 2 respectively by source of the gas, in order to provide the eupnea of user; And be connected with by compress switch 6 steam whistle 7, to sound signal in order to drive steam whistle 7.The length of voice signal is by by 6 controls that compress switch, Manual press pressure handle 61, pressure handle 61 extrudes valve rod 66, valve rod 66 moves to the position being communicated with described intake channel 68 and air outlet passage 65 with movable valve plug 63, at this moment, source of the gas to steam whistle 7, drives steam whistle 7 to sound by intake channel 68, air outlet passage 65.When unclamping pressure handle 61, returning spring 67 moves to the position blocking described intake channel 68 and air outlet passage 65 with movable valve plug 63, after steam whistle 7 does not have source of the gas, then can not sound.
Actual when using, the rules such as the length of sound and sounding number of times can be controlled and encode, carry out corresponding various action, when fire drill, the action of the various instruction of signalling means and correspondence can be drilled, when reality uses, this signalling means can be utilized to organize masses suffering from disaster to escape.This signalling means can act on professional fire-fighting team and use, also can for general public, simple to operate, facilitates.
