Description

Technical Field

[0001] The invention belongs to the technical field of drone bombing, and in particular relates to a drone bombing device suitable for firefighting. Background Art

[0002] Firefighting drones are unmanned aircraft controlled by radio remote control equipment and self-contained programs, and are mainly used in the field of firefighting and rescue. They include many types, such as unmanned helicopters, fixed-wing aircraft, multi-rotor aircraft, unmanned airships and unmanned paragliders. When using drones to drop fire bombs, drone bombing devices are required.

[0003] The existing fire-fighting drone bomb-dropping devices still have some defects. Most of them are prone to jamming when dropping bombs. Since the fire-extinguishing bombs are fixed by two semicircular pipes, when the pipes are opened, their inner walls will block the fire-extinguishing bombs, causing the fire-extinguishing bombs to deviate from the route. The delivery accuracy is low and the delivery structure is complex. For this reason, we propose a drone bomb-dropping device suitable for firefighting. Summary of the invention

[0004] The object of the present invention is to provide a drone bomb dropping device suitable for firefighting, so as to solve the problem in the above-mentioned background technology that most of the bombs are prone to jamming during dropping, causing the fire extinguishing bomb to deviate from the course.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A drone bombing device suitable for fire fighting comprises a drone body and a fixed block, a fixed block is fixed at the bottom of the drone body, a mounting frame is provided on one side of the fixed block, a pressure ring is provided on the top of the fixed block, the pressure ring and the fixed block are fixedly connected, a side ring is provided on one side of the pressure ring, the side ring and the pressure ring are rotatably connected, a support ring is provided on one side of the side ring, the support ring and the side ring are rotatably connected, an insert block is provided at one end of the support ring, the insert block and the support ring are fixedly connected, a storage groove is embedded on one side of the insert block, a first spring is fixed inside the storage groove, a buckle is provided inside the storage groove, a clamping slot is provided at one end of the mounting frame, the buckle and the clamping slot are fixed by clamping, a fixed frame is provided on one side of the mounting frame, an electric telescopic rod is provided on the inner side of the fixed frame, and a pressure block is provided at the output end of the electric telescopic rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The fire extinguishing bomb is fixed and released by means of the mounting frame, the pressing ring, the side ring, the supporting ring, the inserting block, the storage slot, the first spring, the buckle, the slot, the fixing frame, the electric telescopic rod and the pressing block. The fixing is completed by inserting the inserting block into the inner side of the mounting frame and snapping the buckle into the inside of the slot. When releasing the bomb, it is only necessary to start the electric telescopic rod to drive the pressing block to squeeze the buckle to complete the release. The release will not be blocked and the release will be more accurate.

[0016] 2. The fire extinguishing bomb can be better fixed by the fixed sleeve, buffer block, limit block, second spring and pressure plate. When fixing the fire extinguishing bomb, the pressure plate will squeeze the fire extinguishing bomb, thereby driving the buffer block to retract into the interior of the fixed sleeve and compressing the second spring at the same time. After the fixing is completed, the pressure plate will press the fire extinguishing bomb under the reaction force of the second spring, thereby improving stability.

[0017] 3. The flying capability of the UAV is realized through the provided support rod and propeller. The provided support frame makes the UAV more stable when landing. The provided connectors, camera and motor can be used to check the fire situation, so as to drop bombs more accurately. BRIEF DESCRIPTION OF THE DRAWINGS
