Description

Technical Field

[0001] This utility model relates to the field of firefighting drone technology, and in particular to a firefighting drone that is easy to resupply. Background Technology

[0002] Firefighting drones are unmanned aerial vehicles equipped with specialized equipment for firefighting, detection, and rescue, specifically designed to assist or perform firefighting missions. Through real-time image and data analysis, firefighting drones can accurately locate fire sources, assess the spread of fire, monitor toxic gases, and provide decision-making support for command centers. They can also directly drop extinguishing agents, open rescue routes, or airdrop emergency supplies to trapped personnel. Compared to traditional firefighting methods, they offer advantages such as rapid response, flexible perspective, low risk, and high cost-effectiveness, making them an indispensable aerial force in modern intelligent firefighting systems. However, drones have limited payload capacity, meaning they can only carry a limited amount of extinguishing materials per mission, necessitating frequent resupply of water or dry extinguishing powder. Therefore, a drone capable of efficient resupply is needed to improve firefighting efficiency.

[0003] A search revealed a Chinese patent publication number CN114602083B, which discloses an automatic resupply and docking system based on laser vision fusion and its working method. The system includes a resupply platform, a water supply unit, and a drone. The resupply platform is mounted on a mobile fire truck, and the water supply unit is installed on the resupply platform. The drone and the water supply unit can achieve automatic docking through laser vision information fusion. The water supply unit includes a water supply pipe, one end of which is connected to a water tank inside the fire truck.

[0004] To address the issue that each resupply operation in the aforementioned technologies requires the drone to land for docking, which is cumbersome and causes frequent takeoffs and landings that impact internal connectors and affect the lifespan of internal components, a firefighting drone that facilitates resupply is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a firefighting drone that is easy to resupply, so as to solve or alleviate the technical problems existing in the prior art, or at least provide a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: a fire-fighting drone that is easy to resupply includes a drone body and a resupply box. A storage tank is fixedly connected to the lower part of the drone body. A nozzle is fixedly connected to one side of the storage tank. A hose reel is rotatably connected to the lower part of the nozzle. A resupply pipe is wound around one side of the hose reel. An installation plate is fixedly connected to the lower part of the resupply pipe. A docking cone is fixedly connected to the lower part of the installation plate. A docking plate is fixedly connected to the upper part of the resupply box.

[0007] In some embodiments, a water supply pipe is fixedly connected to the inner side of the docking plate, and the water supply pipe is fixedly connected to the supply box through a pipeline. A retaining ring is opened in the middle of the docking plate.

[0008] In some embodiments, the inner side of the mating cone has multiple translation grooves, and an L-shaped plug is slidably connected to the inner side of the translation groove. The bottom of the L-shaped plug has a ramp, and a spring is fixedly connected to one end of the L-shaped plug and the translation groove.

[0009] In some embodiments, a drive ring is rotatably connected inside the mounting plate, and multiple guide platforms and limiting platforms are fixedly connected to the outside of the drive ring.

[0011] In some embodiments, a spray pump is fixedly connected to the bottom of the storage tank, and a spray pipe is fixedly connected to the outlet of the spray pump.

[0012] In some embodiments, a supply pump is fixedly connected to one end of the main body of the drone, a supply pipe is fixedly connected to one end of the supply pump inlet, a supply pump outlet is fixedly connected to the inside of the storage tank, a receiver / discharger is fixedly connected to one end of the nozzle, and the power output end of the receiver / discharger is fixedly connected to the reel.

[0013] In some embodiments, a plurality of magnets are fixedly connected to one side of the mounting plate, and a plurality of electromagnets are fixedly connected to the inner side of the docking plate.

[0014] The present invention has the following advantages due to the adoption of the above technical solution: 1.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example 1: As Figure 1-5As shown, a fire-fighting drone that is easy to resupply includes a drone body 1 and a resupply box 2. Preferably, the drone body 1 is a commercially available drone with a load-bearing capacity. The resupply box 2 is a water tank that stores water. A storage tank 3 is fixedly connected to the lower part of the drone body 1. A nozzle 5 is fixedly connected to one side of the storage tank 3. A hose reel 6 is rotatably connected to the lower part of the nozzle 5. A resupply pipe 7 is wound around one side of the hose reel 6. An installation plate 11 is fixedly connected to the lower part of the resupply pipe 7. A docking cone 12 is fixedly connected to the lower part of the installation plate 11. A docking plate 8 is fixedly connected to the upper part of the resupply box 2. The upper part of the docking plate 8 has a circular arc with an opening in the middle that matches the shape of the docking cone 12. A water supply pipe 14 is fixedly connected to the inner side of the docking plate 8. The water supply pipe 14 is fixedly connected to the supply box 2 through a pipe. A retaining ring 15 is opened in the middle of the docking plate 8. A supply pump 9 is fixedly connected to one end of the main body 1 of the drone. A supply pipe 7 is fixedly connected to one end of the feed inlet of the supply pump 9. The discharge outlet of the supply pump 9 is fixedly connected to the inside of the storage tank 3. A receiver / discharger 10 is fixedly connected to one end of the nozzle 5. The power output end of the receiver / discharger 10 is fixedly connected to the reel 6. When it is necessary to store the storage tank 3, the main body of the drone 1 can be hovered directly above the docking plate 8. Then the reel 6 rotates to lower the mounting plate 11 and docking cone 12 below the supply pipe 7, so that the docking cone 12 can disengage from the arc surface above the docking plate 8. Then, under the influence of gravity, the docking cone 12 will slide down to the opening in the middle of the docking plate 8. After the docking cone 12 is inserted into the opening, its lower part connects with the water supply pipe 14. Then the replenishment pump 9 is started, which can draw water from the replenishment box 2 into the storage tank 3 to replenish the fire extinguishing water. This eliminates the need for precise docking and frequent takeoffs and landings of drones during resupply. Instead, drones can simply hover in the approximate location and use the resupply pipe 7 to pump water for resupply. This makes the operation simpler and causes less impact on drone components.

[0024] In this embodiment, the inner side of the docking cone 12 has multiple translation grooves 17, and an L-shaped plug rod 18 is slidably connected to the inner side of the translation groove 17. The bottom of the L-shaped plug rod 18 has a ramp, and a spring 19 is fixedly connected to one end of the L-shaped plug rod 18 and the translation groove 17. A drive ring 22 is rotatably connected inside the mounting plate 11, and multiple guide platforms 24 and limiting platforms 25 are fixedly connected to the outer side of the drive ring 22. A drive gear ring 23 is fixedly connected above the drive ring 22, and a docking motor 20 is fixedly connected to the inner side of the mounting plate 11. A docking gear 21 is fixedly connected to the power output end of the docking motor 20, and the docking gear 21 and the drive gear ring 23 mesh with each other. When the docking cone 12 is inserted into the hole of the docking plate 8, the docking motor 20 can be started to make the drive ring 22 rotate counterclockwise through the docking gear 21 and the drive gear ring 23. During the rotation, the L-shaped insert rod 18 can be squeezed outward by the arc-shaped guide platform 24. This allows the inclined platform at the bottom of the L-shaped insert rod 18 to be inserted into the retaining ring 15. Then, the inclined platform is used to squeeze the entire docking cone 12 downward, making the docking cone 12 and the water supply pipe 14 below more firmly connected. This prevents the docking from becoming loose due to the shaking of the drone and the wind blowing the supply pipe 7. At the same time, it can also realize the continuous supply mode of pumping water and extinguishing fire at the same time.

[0025] In this embodiment, a spray pump 4 is fixedly connected to the bottom of the storage tank 3, and a spray pipe 5 is fixedly connected to the outlet of the spray pump 4. The spray pump 4 can spray water from the spray pipe 5 at the bottom to extinguish the fire.

[0026] In this embodiment: when it is necessary to store the storage tank 3, the main body of the drone 1 can be hovered directly above the docking plate 8, and then the reel 6 rotates to lower the mounting plate 11 and docking cone 12 below the supply pipe 7, so that the docking cone 12 can release the arc surface above the docking plate 8. Then, under the influence of gravity, the docking cone 12 will slide down to the opening in the middle of the docking plate 8. After the docking cone 12 is inserted into the opening, its lower part connects with the water supply pipe 14. Then the replenishment pump 9 is started, which can draw water from the replenishment box 2 into the storage tank 3 to replenish the fire extinguishing water. This eliminates the need for precise docking and frequent take-offs and landings of drones during resupply. Instead, drones can simply hover in the approximate location and use the resupply pipe 7 to pump water for resupply. This makes the operation simpler and causes less impact on drone components. When the docking cone 12 is inserted into the hole of the docking plate 8, the docking motor 20 can be started to make the drive ring 22 rotate counterclockwise through the docking gear 21 and the drive gear ring 23. During the rotation, the L-shaped insert rod 18 can be squeezed outward by the arc-shaped guide platform 24. This allows the inclined platform at the bottom of the L-shaped insert rod 18 to be inserted into the retaining ring 15. Then, the inclined platform is used to squeeze the entire docking cone 12 downward, making the docking cone 12 and the water supply pipe 14 below more firmly connected, preventing the docking from becoming loose due to the shaking of the UAV and the wind blowing the supply pipe 7. The spray pump 4 can spray water from the bottom nozzle 5 to extinguish the fire.

[0027] Example 2: A firefighting drone that is easy to resupply. This example is an improvement on Example 1, as follows: Figure 1-5 As shown, a plurality of magnets 16 are fixedly connected to one side of the mounting plate 11, and a plurality of electromagnets 13 are fixedly connected to the inner side of the docking plate 8. Preferably, the mounting plate 11, docking cone 12, L-shaped insert rod 18, drive ring 22, guide platform 24 and limiting platform 25 are all made of non-metallic materials. This way, when docking cone 12 and docking plate 8 are docked, the electromagnet 13 can be activated to attract magnet 16, which can make docking faster and improve docking replenishment efficiency.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
