Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing bomb installation technology, and in particular to a fire extinguishing bomb installation structure for a hybrid electric unmanned aerial vehicle. Background Technology

[0002] Hybrid drones are unmanned aerial vehicles powered by hybrid electric power technology. They combine the high energy density of fuel with the high efficiency of electric drive, providing long endurance and high-efficiency flight capabilities. These drones combine the advantages of both fuel engines and electric motors, allowing them to use the fuel engine when high power output is needed and switch to electric mode during cruising to save energy and reduce noise. In recent years, with the frequent occurrence of natural disasters and emergencies, traditional emergency rescue methods have been unable to quickly cover and respond. Hybrid drones, with their unique technological advantages, have become an important innovative tool in the field of emergency rescue. In the event of a fire, by installing fire extinguishing bombs on the underside of the drone, the drone can throw the fire extinguishing bombs at the fire source from a high altitude, allowing the fire extinguishing bombs to extinguish the fire.

[0003] Existing fire extinguishing bombs have the following drawbacks when installed in actual use: Currently, when installing fire extinguishing bombs on the underside of drones, most methods involve suspending the fire extinguishing bombs under the drone using a suspension device. This causes the fire extinguishing bombs to sway after the drone lifts them into the air. Furthermore, when multiple fire extinguishing bombs are suspended, the continuous collision between adjacent fire extinguishing bombs can increase the swaying amplitude, thus affecting the flight stability of the drone. Utility Model Content

[0004] In view of the existing technology, when installing fire extinguishing bombs on the underside of a drone, most of them are suspended by a suspension device. This causes the fire extinguishing bombs to sway after the drone lifts them into the air. Furthermore, when multiple fire extinguishing bombs are suspended, the continuous collision between adjacent fire extinguishing bombs can increase the swaying amplitude, thus affecting the flight stability of the drone. Therefore, this utility model provides a fire extinguishing bomb mounting structure for a hybrid electric drone.

[0005] The technical solution adopted by this utility model is: a fire extinguishing bomb installation structure for a hybrid electric drone, including a drone body and an installation mechanism. The installation mechanism includes a fixed cover, a container, and a limiting plug-in plate. The limiting plug-in plate is fixedly installed on the upper side of the container. A limiting slot is opened on one side of the fixed cover, and the limiting plug-in plate is inserted into the limiting slot. An installation cavity is opened on one side of the fixed cover. A rotating shaft is rotatably installed in the installation cavity. A gear is fixedly installed around the rotating shaft. L-shaped sliding plates are slidably installed on both sides of the inner wall of the installation cavity. A toothed plate is fixedly installed on one side of the L-shaped sliding plate, and the toothed plate meshes with the gear. A limiting block is fixedly installed on one side of one end of the L-shaped sliding plate, and the limiting block is slidably disposed between the limiting slot and the installation cavity.

[0006] Furthermore, there are two L-shaped sliding plates and two toothed plates, with the two L-shaped sliding plates being arranged correspondingly and the two toothed plates being located on both sides of the gear.

[0007] Furthermore, a rotating knob is rotatably mounted on one end of the rotating shaft, and the rotating knob is located on one side of the fixed cover.

[0008] Furthermore, a groove is provided on one side of the rotating knob, and an elastic retaining bead is provided in the groove; a slot is provided on one side of the fixing cover, and the elastic retaining bead is engaged in the slot.

[0009] Furthermore, a connecting column is fixedly installed on the upper side of the fixed cover, and the connecting column is installed on the lower side of the drone body by bolts.

[0010] Furthermore, the container is equipped with a placement cylinder, the upper side of which is provided with a fire extinguishing bomb placement slot, and a mounting slot is provided on one side of the placement cylinder. An electric telescopic rod is fixedly installed in the mounting slot, and a connecting block is fixedly installed at the output end of the electric telescopic rod. A limit plate is fixedly installed on one side of the connecting block.

[0011] Furthermore, two limiting grooves are provided on the lower side of the placement cylinder, and two limiting slide plates are fixedly installed on the upper side of the limiting plate, with the limiting slide plates slidably installed in the limiting grooves.

[0012] The beneficial effects of this utility model are: 1. This utility model, through its installation mechanism, can limit the installation of fire extinguishing bombs when they are mounted on the main body of a drone, thus preventing the fire extinguishing bombs from swaying after the drone takes off, which could affect the flight stability of the drone and improve the practicality of the device.

[0013] 2. Secondly, this utility model, through the electric telescopic rod and the limiting plate, allows the fire extinguishing bomb to be confined within the placement slot after it has been installed. Furthermore, by activating the electric telescopic rod, the limiting plate moves, releasing the sealing of the placement slot and allowing the fire extinguishing bomb to fall towards the fire source, thus further improving the practicality of the device.
