Description

Technical Field

[0001] The utility model relates to the field of fire extinguishing bomb throwing, in particular to a hanging throwing device for aviation fire extinguishing bombs. Background Art

[0002] Aerial fire bombs are a type of ammunition used for fire fighting, usually dropped by aircraft or drones. Its main function is to quickly release fire extinguishing agents at the scene of a fire to extinguish or control the fire. Aerial fire bombs usually consist of a bomb body, a fire extinguishing agent, a fuse, and a parachute. The bomb body is generally made of metal materials and is filled with a fire extinguishing agent. The fire extinguishing agent can be dry powder, foam, water, etc., and the appropriate fire extinguishing agent is selected according to different fire types and fire fighting needs. The fuse is used to detonate the fire extinguishing bomb so that it releases the fire extinguishing agent at the appropriate time and height. The parachute is used to slow down the descent speed of the fire extinguishing bomb to ensure its safe delivery. The advantages of aerial fire bombs are that they can quickly and accurately deliver fire extinguishing agents, have a large coverage area, and have a good fire extinguishing effect. It is suitable for various fire scenes such as forest fires, grassland fires, and urban fires, and can effectively protect people's lives, property, and ecological environment.

[0003] Existing aerial fire extinguishing bombs generally include two types: small-volume and small-weight fire extinguishing bombs and large-volume and large-weight fire extinguishing bombs. Among them, small-volume and small-weight fire extinguishing bombs can be directly hung or vertically hung on the lower part of an aircraft or drone by a single person, but large-volume and large-weight fire extinguishing bombs, such as fire extinguishing bombs weighing 25kg or more, often require the cooperation of multiple people to hang on an aircraft or drone, which is time-consuming and labor-intensive, and has low hanging efficiency.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to improve or solve the technical problem of low suspension efficiency of large-volume and heavy-weight fire-extinguishing bombs in the prior art, the utility model provides a suspension and throwing device for aerial fire-extinguishing bombs. The suspension and throwing device for aerial fire-extinguishing bombs includes: a main body, which is suitable for installation on a drone; a throwing structure, which is installed on the main body; the throwing structure includes a ratchet tensioner installed on the main body, a thrower installed on the main body, and an elastic tensioning belt connecting the ratchet tensioner and the thrower; one end of the elastic tensioning belt is fixed on the ratchet tensioner, and the other end is suspended on the thrower; the thrower is configured to selectively suspend or release the elastic tensioning belt.

[0006] The utility model is used for the suspension and throwing device of the aerial fire extinguishing bomb, which includes a main body and a throwing device, wherein the main body is suitable for being installed on a drone, so as to facilitate the hanging of the aerial fire extinguishing bomb on the drone in cooperation with the throwing structure. The throwing structure includes a ratchet tensioner, a thrower and an elastic tensioning belt, one end of the elastic tensioning belt is fixed on the ratchet tensioner, and the other end can be optionally hung on the thrower. When loading the aerial fire extinguishing bomb, the elastic tensioning belt is pulled out from the ratchet tensioner and laid flat on the ground, the aerial fire extinguishing bomb is moved above the elastic tensioning belt, and then the elastic tensioning belt is hung on the thrower, and the elastic tensioning belt is wound in with the ratchet tensioner to complete the loading of the aerial fire extinguishing bomb. The loading process is simple and convenient, and the loading of the aerial fire extinguishing bomb can be realized by a single person, and the loading efficiency is high. The thrower can selectively hang or release the elastic tensioning belt, so that the aerial fire extinguishing bomb can be automatically thrown after being lifted off. Through the above arrangement, the loading process of the aviation fire extinguishing bomb in the suspension throwing device for the aviation fire extinguishing bomb of the utility model is simple and convenient, and the loading of the aviation fire extinguishing bomb can be realized by a single person, and the loading efficiency is high.

[0007] In the preferred technical solution of the above-mentioned suspension and throwing device for aerial fire extinguishing bombs, a fixed carbon plate is arranged on the main body, and a mounting bracket suitable for connecting to the drone is arranged on the fixed carbon plate. Through the above-mentioned arrangement, the fixed carbon plate has high strength and is light, which can reduce the overall weight of the suspension and throwing device; the mounting bracket can be connected to the drone more conveniently, making the entire suspension and throwing device compact in structure and flexible and convenient to use.

[0008] In the preferred technical solution of the suspension throwing device for aviation fire extinguishing bombs, the throwing device is connected to a controller, and the controller is installed on the fixed carbon plate. Through the above arrangement, the arrangement of the controller facilitates the remote control of the throwing device.

[0009] In the preferred technical solution of the suspension throwing device for the above-mentioned aerial fire extinguishing bomb, an arc plate is arranged on the main body, and the arc plate has an arc surface suitable for matching with the aerial fire extinguishing bomb, and the arc surface faces the elastic tensioning belt. Through the above-mentioned arrangement, the arrangement of the arc plate can make the aerial fire extinguishing bomb close to the arc surface, thereby enhancing the connection stability between the aerial fire extinguishing bomb and the suspension throwing device.

[0010] In the preferred technical solution of the suspension throwing device for the above-mentioned aerial fire extinguishing bomb, a hanging ring is provided at one end of the elastic tensioning belt away from the ratchet tensioner; and a hook matching the hanging ring is provided on the throwing device.

The elastic tensioning belt will interfere with the falling posture of the aerial fire extinguishing bomb at the moment of throwing, causing the aerial fire extinguishing bomb to somersault or not head down during the falling process, affecting the spraying effect of the fire extinguishing agent after the explosion of the aerial fire extinguishing bomb. Through the above-mentioned setting, the setting of the elastic belt can make the elastic tensioning belt shrink to one side of the ratchet tensioner as a whole after the throwing device releases the elastic tensioning belt, reducing the interference of the elastic tensioning belt with the gravity free fall posture of the aerial fire extinguishing bomb at the moment of throwing, thereby obtaining a better fire extinguishing effect.

[0012] In the preferred technical solution of the above-mentioned suspension and throwing device for the aerial fire extinguishing bomb, the ratchet tensioner includes a shell mounted on the main body, a ratchet in rotational connection with the shell, a rotating column that rotates synchronously with the ratchet, a handle that drives the ratchet to rotate, and a locking baffle that forms a sliding connection with the shell and abuts against the ratchet; the elastic tensioning belt is fixed on the rotating column. Through the above-mentioned arrangement, the handle is used to drive the ratchet to rotate, thereby winding the elastic tensioning belt to lock the aerial fire extinguishing bomb on the suspension and throwing device; the locking baffle is used to prevent the ratchet from rotating in the opposite direction.

[0013] In the preferred technical solution of the above-mentioned suspension and throwing device for aerial fire extinguishing bombs, a slide groove for limiting the sliding direction of the locking baffle is provided on the outer shell, and a limit plate for plug-in cooperation with the locking baffle is formed on the outer shell; a compression spring is arranged between the limit plate and the locking baffle.
