Abstract
The utility model is a kind of liquid carbon dioxide vaporization shooting throwing arm, and the rear port of launching tube is arranged on the front side wall of air accumulator; The front side wall of air accumulator also offer a through-hole and be fixed with the transition conduit that a section is positioned at launching tube; Described transition conduit and described through-hole are coaxially arranged and the internal diameter of transition conduit is greater than the aperture of described through-hole; Pressure limiting sheet for through-hole described in shutoff is installed in described transition conduit, the fastening bolt for withstanding pressure limiting sheet backward is also installed.Rely on liquid carbon dioxide to be propelled fire extinguisher bomb by the high velocity air adding thermal initiation generation, structure is simple, and low cost of manufacture is easy to operate, is convenient to transport, safe and reliable.
Description
Technical field
The utility model relates to a kind of fire extinguishing bullet launching device of fire-fighting domain.
Background technology
The existing emitter of fire extinguisher bomb is generally rocket launcher or mortar.Its major defect is: rely on fuel combustion or gunpowder explosion as propelling power, complex structure, cost is high, has strict demand to operator, and security is poor.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of liquid carbon dioxide to vaporize and shoots throwing arm, utilizes liquid carbon dioxide to ignite the high velocity air produced and propels throwing fire extinguisher bomb, to overcome the defect that existing fire extinguisher bomb launches dress.
In order to solve this technical problem, the utility model by the following technical solutions:
A kind of liquid carbon dioxide vaporization shooting throwing arm, comprise the launching tube for loading fire extinguisher bomb and the air accumulator for loading liquid carbon dioxide, described air accumulator is connected with apparatus to cause bursting, it is characterized in that: the rear port of described launching tube is arranged on the front side wall of air accumulator; The front side wall of air accumulator also offer a through-hole and be fixed with the transition conduit that a section is positioned at launching tube; Described transition conduit and described through-hole are coaxially arranged and the internal diameter of transition conduit is greater than the aperture of described through-hole; Pressure limiting sheet for through-hole described in shutoff is installed in described transition conduit, the fastening bolt for withstanding pressure limiting sheet backward is also installed.
Described fastening bolt with endoporus and outer wall be connected with the inner thread of described transition conduit.
Described launching tube is also provided with sight.
Good effect of the present utility model is:
The utility model relies on liquid carbon dioxide to be propelled fire extinguisher bomb by the high velocity air adding thermal initiation generation, and structure is simple, and low cost of manufacture is easy to operate, is convenient to transport, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As Fig. 1, embodiment of the present utility model comprises the launching tube 3 for loading fire extinguisher bomb 5, also comprising the air accumulator 9 for loading liquid carbon dioxide, air accumulator 9 being separately installed with Pressure gauge 8 and charge valve 11.
Described air accumulator 9 is connected with apparatus to cause bursting 10, and can be arranged on launching tube 3 for the voltage flame proof switch 2 starting apparatus to cause bursting 10, also can be a remote control switch.
The rear port of described launching tube 3 is fixed on the front side wall of air accumulator 9.The front side wall of air accumulator 9 also offer a through-hole and be fixed with the transition conduit that a section is positioned at launching tube 3.Described transition conduit and described through-hole are coaxially arranged and the internal diameter of transition conduit is greater than the aperture of described through-hole.Pressure limiting sheet 7 for through-hole described in shutoff is installed in described transition conduit, the fastening bolt 6 for withstanding pressure limiting sheet 7 backward is also installed in described transition conduit.
Described fastening bolt 6 with endoporus and outer wall be connected with the inner thread of described transition conduit, such as it can be hexagonal plug in a kind of external screw thread.
Described launching tube 3 is also provided with fore sight 1 and rear sight 4.
By having manipulated voltage flame proof switch 2, apparatus to cause bursting 10 is started, the pressurized liquid carbon dioxide in air accumulator 9 detonates rapidly, and high velocity air breaks through pressure limiting sheet 7, enters in launching tube 3, propel fire extinguisher bomb 5 through fastening bolt 6 endoporus.After battery has fired, air accumulator 9 is separated with launching tube 3, unloads fastening bolt 6, change pressure limiting sheet 7, the recycling of emitter can be realized.
Claims (3)
1. a liquid carbon dioxide vaporization shooting throwing arm, comprise the launching tube (3) for loading fire extinguisher bomb (5) and the air accumulator (9) for loading liquid carbon dioxide, described air accumulator (9) is connected with apparatus to cause bursting (10), it is characterized in that: the rear port of described launching tube (3) is arranged on the front side wall of air accumulator (9); The front side wall of air accumulator (9) also offer a through-hole and be fixed with the transition conduit that a section is positioned at launching tube (3); Described transition conduit and described through-hole are coaxially arranged and the internal diameter of transition conduit is greater than the aperture of described through-hole; Pressure limiting sheet (7) for through-hole described in shutoff is installed in described transition conduit, the fastening bolt (6) for withstanding pressure limiting sheet (7) backward is also installed.
2. liquid carbon dioxide vaporization shooting throwing arm as claimed in claim 1, is characterized in that: described fastening bolt (6) with endoporus and outer wall be connected with the inner thread of described transition conduit.
3. liquid carbon dioxide vaporization shooting throwing arm as claimed in claim 1 or 2, is characterized in that: (3) are also provided with sight to described launching tube.
