The two ends of the bomb storage shell 2 are penetrated and are respectively set as a bomb throwing end and a bomb adding end, and the bomb storage shell 2 is downwardly inclined and distributed towards the bomb throwing end. The inclined design is beneficial to the movement of the fire extinguishing bombs to the bomb throwing end under the action of gravity.
[0027] Further, the bomb releasing mechanism is arranged at the bomb throwing end of the bomb storage shell 2 and is used for forming a fire extinguishing bomb retention cavity at the bomb throwing end of the bomb storage shell 2. The fire extinguishing bomb retention cavity can only accommodate a single fire extinguishing bomb, and the bomb releasing mechanism can throw the single fire extinguishing bomb. Specifically, the bomb releasing mechanism comprises a first bomb throwing baffle 3 and a second bomb throwing baffle 4 which are arranged at the bomb throwing end of the bomb storage shell 2 and are inserted from the side wall of the bomb storage shell 2. A push-pull piece 5 is arranged on the bomb storage shell 2 and is used for driving the first bomb throwing baffle 3 and the second bomb throwing baffle 4 to be separately inserted into or separated from the bomb storage shell 2. In the embodiment, the push-pull piece 5 is a mechanical transmission structure connected with the first bomb throwing baffle 3 and the second bomb throwing baffle 4, and the push-pull control can be realized through external operation. The space between the first bomb throwing baffle 3 and the second bomb throwing baffle 4 in the bomb storage shell 2 is the fire extinguishing bomb retention cavity.
[0028] Further, in the present embodiment, the loading end of the cartridge 2 is provided with a loading blocking plate 7, which can limit the falling of the fire extinguishing bomb from the loading end of the cartridge 2, and the loading blocking plate 7 can be pulled out from the top of the cartridge 2, facilitating the addition of the fire extinguishing bomb into the cartridge 2. The top wall of the cartridge 2 is provided with a plug hole 11 for the insertion of the first bomb throwing baffle 3, the second bomb throwing baffle 4 and the loading blocking plate 7, and the top end of the first bomb throwing baffle 3, the second bomb throwing baffle 4 and the loading blocking plate 7 is provided with a lug 9, which facilitates the insertion and pulling out of the first bomb throwing baffle 3, the second bomb throwing baffle 4 and the loading blocking plate 7.

[0030] Working principle:
[0031] When the fire extinguishing bomb needs to be thrown and released, the controller 17 is first used to control the electric push rod 10 to pull out the second bomb throwing baffle 4 from the cartridge 2. Since the cartridge 2 is inclined downward towards the bomb throwing end, under the action of gravity, a single fire extinguishing bomb will enter the fire extinguishing bomb retention cavity between the first bomb throwing baffle 3 and the second bomb throwing baffle 4. Then, the controller 17 controls the electric push rod 10 to insert the second bomb throwing baffle 4 into the cartridge 2, so as to limit the fire extinguishing bomb in the fire extinguishing bomb retention cavity. Then, the controller 17 controls the electric push rod 10 to pull out the first bomb throwing baffle 3 from the cartridge 2, at this time, the fire extinguishing bomb in the fire extinguishing bomb retention cavity loses the block of the first bomb throwing baffle 3, and is thrown and released from the bomb throwing end under the action of gravity. Through the continuous operation, the insertion and pulling out of the first bomb throwing baffle 3 and the second bomb throwing baffle 4 can be accurately controlled by the controller 17, so as to realize the single throwing and releasing of the fire extinguishing bomb.
[0032] All the technical features in the present embodiment can be freely combined according to actual needs.
