Description

Technical Field

[0001] The utility model relates to the technical field of forest fire fighting and extinguishing, and particularly relates to an unmanned aerial vehicle (UAV) forest fire fighting and extinguishing throwing structure. Background Art

[0002] The situation of forest fire prevention is severe, and the frequency and scale of forest fires are on the rise. Traditional fire fighting tools are unable to cope in complex terrains and large-scale fires. Fire extinguishing bombs are often used in forest and grassland fires, with advantages such as great power, remarkable fire extinguishing effect, and wide application range. Using UAVs to load fire extinguishing bombs and throw them at the fire starting point brings new breakthroughs to forest fire prevention. UAVs can reach locations that are difficult for rescue personnel to reach, improve the fire extinguishing efficiency and speed, and contribute to protecting forest resources and the ecological environment.

[0003] The patent publication number "CN218777684U" discloses "a UAV forest fire extinguishing bomb throwing device", which includes a receiving shell with an open top and a throwing mechanism; the throwing mechanism includes a guiding cylinder with one end open, the guiding cylinder is horizontally fixedly connected to one side of the bottom of the receiving shell, the other end of the top of the guiding cylinder is vertically communicated with a connecting pipe, and the top end of the connecting pipe is communicated with one side of the inner cavity bottom of the receiving shell. In this UAV forest fire extinguishing bomb throwing device, after the driving motor drives the cross plate to rotate and the blocking block is located below the through hole, the electric telescopic rod contracts to drive the blocking block to block the through hole, so that after the spherical fire extinguishing bomb falls into the guiding cylinder, the electric slide rail drives the moving plate to move, and then the spherical fire extinguishing bomb inside the guiding cylinder is pushed out and falls in a parabola, improving the safety of the UAV during the fire extinguishing process and facilitating the throwing of the spherical fire extinguishing bomb into the buildings of forest sanitation workers' residences for fire extinguishing.

[0004] The device in the above patent can be conveniently connected and fixed to the UAV through the connecting plate and the threaded hole, so as to facilitate installation and use. However, if the connecting plate and the threaded hole cannot effectively perform multi-directional movement adjustment, then in actual application scenarios, it may be difficult to efficiently connect and fix to UAVs of different models. Once such a situation occurs, the connection method will appear to be relatively single and difficult to adapt to many types of UAVs and other related problems. Summary of the Utility Model

[0051] The pushing mechanism 4 drives the push plate 44 installed at the sliding end to move by means of the electric slide rail 43 installed between the two ends of the inner wall of the sliding slot 42. The moving push plate 44 can effectively push the falling fire extinguishing bombs for throwing operations. In this way, it is possible to throw and extinguish the flames burning at relatively high positions, thereby preventing the flames from roasting the operation of the drone and ensuring that the drone can work stably and safely when performing fire - extinguishing tasks. The sliding slot 42 is opened on one side of the inner wall of the connection channel 41 and penetrates through the interior. One end of the push plate 44 penetrates through one side of the sliding slot 42 and is installed at the sliding end of the electric slide rail 43.
