Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting unmanned aerial vehicles, and in particular to a loading platform for fire-fighting unmanned aerial vehicles. Background Art

[0002] Firefighting drones are a new type of drone technology used in the field of firefighting. They have multiple functions and advantages and play an important role in fire rescue and forest fire prevention. First of all, firefighting drones can be equipped with various firefighting equipment, such as fire extinguishers and water guns, and can directly participate in firefighting. They can quickly reach the scene of the fire, conduct high-altitude reconnaissance and monitoring, provide rescue personnel with real-time and accurate fire information, and help to formulate more scientific and effective rescue plans. Secondly, firefighting drones also have remote control and autonomous flight capabilities, and can carry out rescue operations in dangerous environments to reduce the risk of casualties. They can carry out real-time monitoring and early warning of the fire scene by carrying cameras, infrared detectors and other equipment, timely discover the source of the fire and control the spread of the fire. In addition, firefighting drones can also be used for forest fire prevention. They can fly over complex terrain and vegetation, conduct all-round and no-dead-angle monitoring and patrol of the forest, and promptly discover the fire and alarm. At the same time, firefighting drones can also carry fire extinguishing agents for aerial firefighting operations to effectively curb the spread of forest fires.

[0003] Firefighting drones should minimize the volume of the items being transported, and the boxes carrying the items need to avoid being hit hard during landing. However, the volume of the boxes currently used for transportation is fixed, and the capacity is not easy to adjust. No matter how many items are transported, the volume is fixed, which occupies a large space, and the boxes are easily hit hard when they land. To solve the above problems, we propose a loading platform for firefighting drones. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a loading platform for a fire-fighting drone.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A loading platform for a firefighting drone comprises a main storage box body, an auxiliary storage box body is slidably sleeved inside the main storage box body, a base is installed at the bottom of the main storage box body through a buffer mechanism, a height adjustment mechanism for adjusting the height of the auxiliary storage box body is installed inside the auxiliary storage box body, a plurality of fan-shaped holes are opened on the top of the auxiliary storage box body, a box cover is hinged in the fan-shaped holes, and a hook assembly is installed on the box cover.

[0007] Preferably, the buffer mechanism comprises a damper, a pressure plate, an inclined block, a sliding column, and a spring. The sliding column is T-shaped, fixed to the bottom of the main receiving box body, and the sliding column is slidably sleeved in the base. The damper is installed at the bottom of the main receiving box body. A pressure plate is fixed to the buffer end of the damper, and an inclined block is fixed to the pressure plate. The inner wall of the base is an inclined surface structure matching the inclined block.

[0008] Preferably, a T-shaped sliding hole is provided on the base, the sliding post is slidably sleeved in the sliding hole, and a spring is connected between the sliding post and the inner wall of the sliding hole.

[0009] Preferably, the base is an annular structure, and a rubber gasket is fixed to the bottom of the base.

[0010] Preferably, the height adjustment mechanism includes a second stud, a boss, a first nut, and a second nut. The second stud is fixed in the main storage box body. The second stud is movably sleeved with a boss. The boss is fixed on the inner wall of the auxiliary storage box body. The second stud is threadedly sleeved with a first nut and a second nut. The first nut is located above the boss, and the second nut is located below the boss.

[0011] Preferably, a plurality of partitions are fixed inside the main storage box.

[0012] Preferably, a sliding block is fixed to the side of the auxiliary storage box body, and a sliding groove is provided on the inner wall of the main storage box body, and the sliding block is slidably installed in the sliding groove.

[0013] Preferably, the hook assembly includes a first stud, a first lifting ring, a wire rope, and a second lifting ring, wherein the second lifting ring is connected to a plurality of first lifting rings via a wire rope, the first lifting ring is fixed with a first stud, and the first stud is threadedly sleeved in the box cover.

[0014] Preferably, the auxiliary storage box body and the box cover are fixed by bolts.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, when the base contacts the ground, the base slides on the sliding column. At this time, the inclined surface structure of the inner wall of the base will squeeze the inclined block, and the inclined block will translate and squeeze the damper through the pressure plate to achieve buffering, reduce the impact on the stored items, and have a protective effect;

[0017] 2. In the present invention, the position of the boss on the second stud can be adjusted by adjusting the positions of the first nut and the second nut, thereby adjusting the height of the boss. Since the boss is fixed to the inner wall of the auxiliary storage box, the height of the auxiliary storage box can be adjusted synchronously. By sliding the auxiliary storage box in the main storage box, the size of the storage space formed by the main storage box and the auxiliary storage box can be adjusted, which is convenient for adjustment according to actual needs and does not need to occupy too much space under the condition of satisfying the installation.

[0018] 3. In the present invention, the hook assembly is used for the overall suspension and lifting of the drone. The first stud is connected to the box cover by threads for easy disassembly and assembly, and the second lifting ring is connected to the hook of the drone. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figure 2 The buffer mechanism 3 includes a damper 31, a pressure plate 32, an inclined block 33, a sliding column 34, and a spring 35. The sliding column 34 is T-shaped, the sliding column 34 is fixed to the bottom of the main storage box body 1, and the sliding column 34 is slidably sleeved in the base 4. The damper 31 is installed at the bottom of the main storage box body 1, and the buffer end of the damper 31 is fixed with a pressure plate 32, and the inclined block 33 is fixed on the pressure plate 32. The inner wall of the base 4 is an inclined structure matching the inclined block 33. A T-shaped sliding hole is opened on the base 4, and the sliding column 34 is slidably sleeved in the sliding hole. A spring 35 is connected between the sliding column 34 and the inner wall of the sliding hole. The base 4 is an annular structure, and a rubber gasket 13 is fixed to the bottom of the base 4. When the base 4 contacts the ground, the base 4 slides on the sliding column 34. At this time, the inclined surface structure of the inner wall of the base 4 will squeeze the inclined block 33, and the inclined block 33 translates and squeezes the damper 31 through the pressure plate 32 to achieve buffering.
