Description
Technical field
Originally practical to belong to firefighting cartridge apparatus field, and in particular to be that a kind of emit for firefighting cartridge uses nitrogen for medium
Pop-up engine.
Background technique
Currently, increasing with skyscraper, high level is put out a fire the problem of becoming people's critical concern, and aerial ladder of fire truck is only
10 layers of fire below can be put out, at present for high-rise no effective measures of putting out a fire, need to start in view of the transmitting of current fire extinguisher bomb
Machine provides big power, guarantees fire extinguisher bomb in regulation flight range, bullet declines in allowed band, this just needs fire extinguisher bomb to start
Machine pressure vessel can bear high pressure, to provide big power, existing unmanned aerial vehicle onboard fire extinguisher bomb launch power source is rocket
There are the standard pressure vessels needed for the management of priming system and transportation safety, existing suitable firefighting cartridge emit in transmitting,
It bears pressure and is not able to satisfy mission need.
Summary of the invention
This practical purpose is in view of the above shortcomings of the prior art, and to provide a kind of firefighting cartridge pop-up engine, it
It is that gas storage shell is filled with to a certain amount of pressure nitrogen, by relieving mechanism abrupt release gas, is realized and emitted using thrust gas
Firefighting cartridge, has taken leave of using and managing for priming system, and emission process Recoilless does not impact unmanned plane, using carbon fiber
Dimension winding storage cylinder mitigates pop-up engine weight, improves gas storage pressure.
To achieve the above object, originally practical to provide the following technical solutions: a kind of firefighting cartridge pop-up engine, before it includes

Sealing sleeve pipe of the spinning in connection housing；The front end of the gas storage shell is connected with seal plug by sealing ring；It is described close
Cylinder body is coaxially arranged with by multiple connecting ribs being uniformly arranged in big envelope pipe；Unlatching piston is provided in the cylinder body；Institute
State open piston outer end and sealing sleeve pipe compressed gas liberation port sealing cooperate, open piston be located at the intracorporal one end of cylinder and
Reset compressed spring is provided between cylinder base；It is provided in the rear end for being located at cylinder body for compressed air in release cylinder body
Relieving mechanism；The relieving mechanism is opened by the electric initiator for being connected to relieving mechanism rear end, the cylinder body and relieving mechanism it
Between offer air hole for being connected to inner chamber of cylinder block Yu relieving mechanism inner cavity.
Preferably, the relieving mechanism includes that the release shell for being connected to rear end of the cylinder block and sealing are slidably mounted on release
Piston in housing cavity, described discharge radially offer multiple gas vents around release shell axis setting on shell.
Preferably, the outer end end face of the piston and the sealing cooperation of the compressed gas liberation port of sealing sleeve pipe is provided with screw thread
Plug.
Preferably, the gas storage hull outside is wound with carbon fiber layer.
This practical principle is: general mechanical mechanism cannot achieve moment unlatching relieving mechanism under high pressure, will store
Gas abrupt release, firefighting cartridge pop-up engine need quick using pilot-operated type opener, pilot section therein
It is accurate to open channel, and guarantee unimpeded；Fire extinguisher bomb pop-up engine nozzle is changed to Bearing score nozzle, is discharging high pressure gas
Pilot mechanism opens moment formation high-pressure nozzle channel, substantially increases the utilization rate of gas, this design makes pop-up engine
It is compact-sized, alleviate fire extinguisher bomb pop-up engine overall weight, high pressure gas when emitting fire extinguisher bomb using Bearing score nozzle
Steadily quickly through to improve transmitting precision, it is ensured that fire extinguisher bomb accurately steadily emits to target；Connect housing and storage
Gas cylinder connection type is changed to O-ring end face seal and adds smearing screw thread glue form, solves screw thread because one-sided sealant is smeared not
Uniformly lead to seal bad, gas leak phenomenon, replacement easy to disassemble provides safe guarantor for firefighting cartridge pop-up engine use
Barrier.
The firefighting cartridge pop-up engine is that high pressure gas emits no priming system, not will cause the secondary destruction in scene, therefore
It can be used for scene of fire fire fighting and rescue.Firefighting cartridge pop-up engine does not have recoil when emitting, and normally flies to unmanned plane
Row does not influence, and is adapted to multi-model unmanned plane suspension mission need.If unmanned plane power is big, can be assembled with multiple groups firefighting cartridge
Cluster emits together, it is ensured that fire-fighting fire extinguishing is safe and reliable.It replaces and repeats through disassembled simply because of fire extinguisher bomb pop-up engine
It uses, and single emission cost, well below rocket launching cost, easy to operate, filled media is nitrogen, emission process
It not can cause environmental pollution, it is originally practical to can be used for the usual training exercise of army.
This practical beneficial effect is: on the basis of carbon fiber winding, pressure vessel storage pressure is considerably increased, from
And increase transmitting range, it is lighted a fire using pilot mechanism, opens air cavity channel, the nitrogen of abrupt release storage reaches hair
The purpose for penetrating fire extinguisher bomb, improving high pressure gas capacity usage ratio using nozzle makes fire extinguisher bomb smooth flight, and it is accurate to improve transmitting
Degree；Existing unmanned aerial vehicle onboard fire extinguisher bomb launch power source is rocket launching, there are problems that the management of priming system and transportation safety,
And this patent uses nitrogen as medium and is emitted, no pollution to the environment, solves priming system problem of management, and actuating mechanism
It is simple and efficient, can under high pressure moment open, firefighting cartridge pop-up engine may be reused by simple cleaning after transmitting.
Made using Bearing score nozzle compact-sized, improves gas energy utilization rate；This it is practical can using carry in small drone as
Emit fire extinguisher bomb power source, which employs nitrogen as filled media, no pollution to the environment, Neng Gouan
Complete reliable storage 26MPa high pressure gas, and can quickly, accurately open release channel, general mechanical mechanism is under high pressure
It cannot achieve.Recoilless in emission process will not impact unmanned plane, improve the accuracy of transmitting.The patent is adopted
With carbon fiber winding storage cylinder, Lai Tigao compressive resistance guarantees safe and reliable.It is reusable by disassembled simply.
