Description

Technical Field

[0001] This utility model relates to the field of material delivery, specifically to an unmanned aerial vehicle (UAV) urban fire emergency material delivery device. Background Technology

[0002] In urban fire emergency rescue scenarios, sudden accidents such as fires, earthquakes, and building collapses occur frequently, often resulting in road blockages and blocked rescue channels, making it difficult for ground rescue forces to reach the scene quickly. At this time, drones, with their advantages of flexibility, mobility, and rapid response, have become an important carrier for emergency material delivery and play a key role in improving the efficiency of emergency rescue. As a supporting core equipment, the drone urban fire emergency material delivery device directly determines whether emergency materials can be delivered safely and intact to the target location.

[0003] Most commercially available drone-based emergency supply delivery devices currently on the market adopt a container structure. The design concept is to centrally store fire emergency supplies inside the container, then use a drone to carry the container to the target rescue area, and finally release the container via a delivery mechanism, allowing the container carrying the supplies to fall to the ground. However, due to the complex ground environment in urban rescue scenarios, the container experiences a violent impact when it falls from the air to the ground. Most existing container structures lack effective cushioning and vibration reduction designs, and this impact is directly transmitted to the emergency supplies inside the container. Among fire emergency supplies, whether it is first aid medicine, precision detection instruments, or fragile fire-fighting equipment, they are all unable to withstand the violent impact, often resulting in problems such as medicine failure, instrument damage, and equipment deformation, rendering the delivered supplies unusable and delaying rescue opportunities.

[0004] To address this, a drone-based urban fire emergency material delivery device is proposed. Utility Model Content

[0005] In view of the problems existing in the current UAV urban fire emergency material delivery device, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an unmanned aerial vehicle (UAV) urban fire emergency material delivery device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A drone-based urban fire emergency material delivery device includes a housing and a lid on top of the housing, with a lifting head fixed at the center of the top of the lid. A counterweight is fixedly installed at the center of the bottom of the box. An elastic telescopic rod is fixedly installed at the bottom of the counterweight. An arc-shaped buffer plate is fixedly installed at the lower end of the elastic telescopic rod. A rubber airbag is fixedly installed at the bottom of the box. The counterweight, elastic telescopic rod and arc-shaped buffer plate are all located inside the rubber airbag.

[0008] Preferably, the weight is a conical block, and the tip of the weight is set downwards.

[0009] Preferably, the elastic telescopic rod includes a square sleeve fixedly disposed at the bottom of the weight block, a square connecting rod slidably disposed at the lower end of the square sleeve, a first spring fixedly disposed between the upper end of the square connecting rod and the inner wall of the square sleeve, and the lower end of the square connecting rod fixedly connected to the inner wall of the arc-shaped buffer plate.

[0010] Preferably, the curvature of the outer side of the arc-shaped buffer plate matches the curvature of the inner sidewall of the rubber airbag.

[0011] Preferably, an anti-tipping ring is fixedly provided at the bottom of the outer side wall of the box, and the surface of the anti-tipping ring is provided with a plurality of evenly distributed drag-reducing holes.

[0012] Preferably, the lid and the body of the box are connected by threads.

[0013] Preferably, the interior of the box is symmetrically provided with two arc-shaped clamps, and a second spring is fixed between the side walls of the two arc-shaped clamps and the inner side wall of the box.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: The conical counterweight at the bottom of the container in this invention can precisely adjust the center of gravity, ensuring that the container and its contents remain horizontal during descent, avoiding tilting or overturning caused by airflow interference, and solving the problems of uncontrolled descent and landing point deviation in traditional containers. At the same time, the anti-tipping ring at the bottom of the outer wall of the container can prevent it from tipping over after landing, and the drag-reducing holes can reduce the impact of air resistance on the descent trajectory, allowing emergency supplies to accurately reach the target rescue area and meet the delivery needs in complex urban environments.

[0015] This utility model adopts a dual external buffer structure of "initial buffering with rubber airbags + secondary energy absorption with elastic telescopic rods". The rubber airbags can directly absorb part of the impact force upon landing. The arc-shaped buffer plate, together with the deformation of the first spring of the elastic telescopic rod, can further offset the remaining impact force and prevent the impact force from being directly transmitted into the box. At the same time, the arc-shaped clamping plate inside the box clamps the materials through the second spring, reducing the shaking and collision of the materials. The dual protection can effectively protect emergency medicines, precision detection instruments, vulnerable fire-fighting equipment and other materials, preventing problems such as medicine failure, instrument damage, and equipment deformation, and ensuring that the materials can be used normally after delivery.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides, for example Figure 1-5The device shown is a drone-based urban fire emergency material delivery device, comprising a housing 1 and a cover 2 on top of the housing 1. The cover 2 is threadedly connected to the housing 1, which not only improves the sealing between the housing 1 and the cover 2, but also facilitates the opening of the cover 2. A lifting head 3 is fixedly installed at the center of the top of the cover 2. The lifting head 3 is connected to the drone via a mechanical structure for quick assembly and disassembly. Opening the mechanical structure allows the housing 1 to be lowered. A counterweight 4 is fixedly installed at the center of the bottom of the housing 1. The counterweight 4 is a conical block with its tip pointing downwards. The counterweight 4 ensures that the bottom center of gravity of the housing 1 is always downwards, ensuring that the housing 1 and the materials inside are always facing downwards. An elastic telescopic rod 5 is fixedly installed at the bottom of the counterweight 4, and the lower end of the elastic telescopic rod 5 is fixed... An arc-shaped buffer plate 6 is provided, and a rubber airbag 7 is fixedly provided at the bottom of the box body 1. The counterweight 4, the elastic telescopic rod 5, and the arc-shaped buffer plate 6 are all located inside the rubber airbag 7. The curvature of the outer side of the arc-shaped buffer plate 6 matches the curvature of the inner side wall of the rubber airbag 7. The elastic telescopic rod 5 includes a square sleeve 51 fixedly provided at the bottom of the counterweight 4. A square connecting rod 52 is slidably provided at the lower end of the square sleeve 51. A first spring 53 is fixedly provided between the upper end of the square connecting rod 52 and the inner wall of the square sleeve 51. The lower end of the square connecting rod 52 is fixedly connected to the inner wall of the arc-shaped buffer plate 6. The square structure design here makes it so that the square connecting rod 52 will not rotate inside the square sleeve 51, and the square sleeve 51 can only slide up and down inside the square connecting rod 52.

[0021] An anti-tipping ring 8 is fixedly installed on the bottom of the outer side wall of the box 1. The surface of the anti-tipping ring 8 has multiple evenly distributed drag-reducing holes 9, which can reduce air resistance during the fall. When the box 1 lands, it will tilt. At this time, the edge of the anti-tipping ring 8 will contact the ground to prevent the box 1 from tipping over. Two arc-shaped clamps 10 are symmetrically arranged inside the box 1. A second spring 11 is fixed between the side wall of the two arc-shaped clamps 10 and the inner side wall of the box 1. When the materials are placed between the two arc-shaped clamps 10, the arc-shaped clamps 10 can clamp the materials through the action of the second spring 11.

[0022] Working principle: The device is connected to the drone through the lifting head 3 on the top of the box cover 2 to realize the loading and transportation of emergency supplies. The threaded connection between the box cover 2 and the box body 1 can ensure that the supplies are sealed during transportation and prevent them from falling. The weight block 4 fixed at the bottom center of the box 1 adopts a cone-shaped design with the tip pointing downwards. It can use its own weight to adjust the center of gravity of the box 1, so that the box 1 and the contents inside can always maintain a horizontal posture during the fall from the air, preventing the box from tilting or flipping due to airflow interference and other factors, ensuring accurate landing position and uniform force when in contact with the ground. When the box 1 falls to the ground and makes contact, the first thing to come into contact with the ground is the rubber airbag 7 at the bottom of the box 1. The rubber airbag 7 can absorb part of the impact force of the landing and play an initial buffering role. At the same time, the arc-shaped buffer plate 6 inside the rubber airbag 7 will also come into contact with the ground. The curvature of its outer side matches the curvature of the inner side wall of the rubber airbag 7, which can evenly transmit the impact force to the elastic telescopic rod 5 connected above. The square connecting rod 52 in the elastic telescopic rod 5 will slide upward along the square sleeve 51 and squeeze the first spring 53 inside. The first spring 53 further absorbs and offsets the remaining impact force through its own deformation, realizing secondary buffering. In addition, the two arc-shaped clamps 10 symmetrically arranged inside the box 1 can clamp and fix the internal materials through the second spring 11 on the side wall, reducing the shaking of the materials inside the box, and forming double protection in conjunction with the external buffer structure. The anti-tipping ring 8 at the bottom of the outer wall of the container 1 can prevent the container from tipping over after landing. The drag-reducing holes 9 on its surface can reduce air resistance during the descent, further ensuring the stability of the delivery process and ultimately achieving comprehensive buffer protection for the emergency supplies inside the container 1.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
