Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing bombs, and in particular to a fire extinguishing bomb unmanned aerial vehicle delivery pod and a launching device. Background Art

[0002] As drone technology matures, fire extinguishing bombs are installed at the bottom of drones, and the use of drop-type fire extinguishing in forests and other fire areas has become increasingly popular. Existing fire extinguishing bombs mainly include two detonation methods: one is the pull-type (active) detonation, and the other is the ignition type (passive) detonation. The pull-type requires pulling out the cable, and the explosion will occur after seven seconds. The ignition type only requires tearing open the cover, taking out the superconducting thermistor and throwing it into the fire to start the combustion. Both of the above detonation methods are not suitable for use on drones. When the fire extinguishing bomb is installed at the bottom of the drone, the fire extinguishing bomb uses a foam shell PVC ball and a dry chemical agent to immediately extinguish the fire through a small explosion. The system uses drones to send fire extinguishing balls into the fire. When it comes into contact with the fire, the ball explodes with a fire extinguisher to extinguish the fire. However, the disadvantage of this structure is that it is not suitable for large-scale fire fighting. Summary of the invention

[0004] In order to achieve the above technical objectives, the present invention adopts a fire-extinguishing bomb drone delivery pod and a launching device, wherein the fire-extinguishing bomb drone delivery pod is composed of a first cylinder and a second cylinder connected in series by a pull rod to form a combined pod structure; a plurality of fire-extinguishing bomb storage compartments in an upper and lower open state are arranged around the pod structure, and a slide rail structure for supporting the fire-extinguishing bomb and launching the fire-extinguishing bomb is arranged in the middle of the storage compartment;

A plurality of fire extinguishing bomb storage compartments 3 in an upper and lower open state are arranged around the pod structure, and a slide rail structure 4 for supporting the fire extinguishing bomb 11 and ejecting the fire extinguishing bomb 11 is arranged in the middle of the storage compartment 3.

[0020] A plurality of air ducts 5 are radially arranged between the first cylinder 1 and the second cylinder 13 . In the present invention, the number of the air ducts 5 is equal to the number of the fire bomb storage compartments 3 . Meanwhile, a high-pressure gas generator 6 is arranged at the center of the first cylinder 1 .

[0021] A four-beam structured handle 8 is provided on the upper end surface of the first cylinder 1, and the four-beam structured handle 8 is mechanically fixedly connected to an equal number of pull rods 2, a fixing frame 9 is provided at the waist of the four-beam structured handle 8, and a fire pulling line 12 is connected between the fixing frame 9 and the tail of the fire extinguishing bomb 11.

[0022] In the present invention, the preferred high-pressure gas generator 6 includes: a central gas chamber tube 61, a gas-producing powder package 62, an electric ignition component 63 and a conductive column 64; wherein, one end of the electric ignition component 63 is connected to a socket at one end of the conductive column 64 through a plug; an ignition head is provided at the other end of the electric ignition component 63, and the ignition head is inserted into the blind hole in the center of the gas-producing powder package 62.

[0023] In the above structure, a triple component consisting of a gas-generating powder package 62, an electric ignition component 63 and a conductive column 64 is placed in the inner cavity of a central gas chamber tube 61; the conductive column 64 is mechanically connected to the central gas chamber tube 61; and two power transmission wires 65 extending from one exposed end of the conductive column 64 are connected to the output terminal of a remote control power circuit fixed on the drone.

[0024] Depend on Figure 4 It can be seen that a plurality of air outlet holes 14 are provided at the waist of the central air chamber tube 61, and the number of the air outlet holes 14 is equal to the number of the air duct 5; the air duct 5 is connected to the air outlet holes 14 through the first port 15, and the air duct 5 is connected to the fire extinguisher bomb storage compartment 3 through the second port 16.

[0025] An arresting ring 10 is sleeved on the outer circumferential wall of the first cylinder 1 and the second cylinder 13 to limit the fire extinguishing bomb 11 in the fire extinguishing bomb storage compartment 3 from sliding out freely. The outer circumferential wall of the arresting ring 10 is provided with strong breaking grooves 101 which will forcibly break the fire extinguishing bomb 11 when the fire extinguishing bomb 11 is ejected, and the number of the strong breaking grooves 101 is the same as the number of the fire extinguishing bombs 11.

[0026] The structure of the present invention is specifically used as follows: near the fire scene, the fire extinguishing bombs 11 are placed in the fire extinguishing bomb storage compartment 3 of the pod, the arresting circle 10 is sleeved on the first cylinder 1 and the second cylinder 13 of the pod, and the fire pulling wire 12 at the tail of the fire extinguishing bomb 11 is fixed to the fixing frame 9 of the handle 8 of the four-beam structure.

The power switch is turned on manually through remote control to supply power and ignite the gas-generating powder bag 62. The high-pressure airflow generated by the gas-generating powder bag 62 rushes into the fire-extinguishing bomb storage compartment 3 through the air guide pipe 5. The high-pressure airflow pushes the fire-extinguishing bomb 11 to break through the arresting circle 10 and is ejected in a circular shape. While the fire-extinguishing bomb 11 is ejected, the fire line 12 is pulled to start the delayed ignition device. The fire-extinguishing bomb 11 detonates when it freely falls to a preset height, and the ejected fire extinguishing agent covers the flame to achieve a fire-extinguishing effect.
