Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicle (UAV) transportation technology, and in particular to a novel dual-link refrigerant fire-fighting UAV. Background Art

[0002] Firefighting drones are an emerging firefighting tool. Equipped with infrared thermal imaging cameras and visible light cameras, they can quickly locate fire sources in complex environments such as dense smoke and at night. Using AI algorithms, they analyze fire spread trends in real time. Using lidar and multispectral sensors, drones generate three-dimensional models of the fire scene, assisting with post-disaster damage assessment and rescue route planning. Drones can carry water-based, dry powder, or foam fire extinguishing bombs, and utilize GPS and obstacle avoidance algorithms to precisely deliver them to the core of the fire source. These drones are suitable for fires in high-rise buildings and involving hazardous chemicals.

[0003] However, existing firefighting drones still have the following defects:

[0004] 1. Payload Capacity and Endurance Limitations

[0005] Problem: Most drones have limited payload (usually less than 50kg), making it difficult to carry enough fire extinguishing agents or large equipment. Furthermore, their battery life is short (approximately 30-60 minutes), making it difficult to handle long-term missions.

[0006] Reason: The contradiction between the technical bottleneck of the power system (such as the low energy density of lithium batteries) and the lightweight design of the fuselage.

[0007] 2. Firefighting Efficiency and Coverage Limitations

[0008] Problem: Traditional spraying drones rely on close-range operations, and the spread of fire extinguishing agents is greatly affected by wind, making it difficult to cover the tops of high-rise buildings or narrow spaces.

[0009] Cause: The sprinkler system design is simple and lacks the ability to deliver fire in a targeted manner to high-altitude fire sources. Diversified fire bomb types can fill the blind spots that traditional sprinklers cannot reach.

[0010] Therefore, it is urgent to design a new type of dual-link refrigerant fire-fighting drone. Summary of the Invention

[0011] The purpose of the present invention is to provide a new type of dual-link refrigerant fire-fighting drone to solve the problems raised in the above background technology.

[0043] Example

[0044] See also Figure 1-Figure 7The present invention provides a novel dual-link refrigerant firefighting drone, comprising a drone body 1. An air reservoir 2 and a cannon barrel 3 are disposed above the drone body 1. A sealing assembly 41 is provided at the junction of the cannon barrel 3 and the air reservoir 2. A fixed bracket 5 is disposed outside the air reservoir 2. A loading assembly 6 is disposed on the fixed bracket 5. The outlet of the loading assembly 6 is connected to the inlet of the cannon barrel 3. A wing assembly 7 and a camera assembly 8 are disposed below the drone body 1. The camera assembly 8 is disposed at the front of the drone body 1.

[0045] An air outlet is provided on the side of the gas reservoir 2 closest to the barrel 3, and a cap 21 is provided on the other side of the gas reservoir 2, away from the barrel 3. A rotating drum 9 is sheathed around the barrel 3, with a through opening that mates with the inlet. A groove 31 is defined in the middle of the barrel 3, and a corresponding ridge 91 is provided on the inner side of the rotating drum 9. This ridge 91 is a rubber strip that mates with the groove 31 for sealing. Grease lubricates the rubber strip and the groove 31.

[0046] Both ends of the barrel 3 are provided with annular grooves, each containing a plurality of rotating balls 32. These balls 32 are in contact with the rotating drum 9, enabling the drum 9 to rotate about the barrel 3. A friction wheel 93 is provided below the rotating drum 9. The friction wheel 93 is fixedly mounted on the output end of a friction motor 92, which is fixed to the drone body 1. The rotation of the friction motor 92 drives the friction wheel 93 to rotate, which, in conjunction with the rotating balls 32, drives the rotating drum 9, which is in contact with the friction wheel 93, to rotate, sealing the drug inlet on the barrel 3.

[0047] The plug 41 assembly includes a plug 41, a cam 42, and a plug 43. One end of the plug 43 passes through the air outlet and is arranged inside the gas cylinder 2. The plug 43 and the gas cylinder 2 are designed with a magnetic buckle and are connected by magnetic attraction. The other end of the plug 43 is connected to one end of the plug 41, and the other end of the plug 41 is connected to the barrel 3 via a sealing ring 44. The plug 43 is provided with a perforation, which is passed through by one end of a rocking arm 45. The other end of the rocking arm 45 is connected to the cam 42, and the cam 42 is connected to the output end of the rocking motor 46. The rotation of the output end of the rocking motor 46 drives the cam 42 to rotate continuously, so that the air outlet of the gas cylinder 2 and the air inlet of the barrel 3 are opened, and the gas pushes the fire bomb out.

[0048] The loading assembly 6 includes a fixing rod 61 provided on the fixing bracket 5. One end of the fixing rod 61 passes through the annular plate 62 and is connected to the arc plate 63. The arc plate 63 is provided above the ball hole. The other end of the fixing rod 61 passes through the top cover 64 and is connected to the rotating cover 65. Figure 6As shown, multiple fixing rods 61 are provided and arranged in a ring shape to form an annular channel for loading fire bombs. The fire bombs are first stored in the annular channel. When the sealing component 41 opens the air inlet and the air outlet at both ends, as the fire bombs in the barrel 3 are continuously fired, the fire bombs in the annular channel are continuously replenished from the medicine inlet. After the loading is completed, the rotating drum 9 rotates under the action of friction and closes the medicine inlet.

[0049] The wing assembly 7 includes a wing support 71, which is provided with multiple sub-frames. Each sub-frame is also provided with an actuator 75 at the lower middle position. Actuator 75 is used to coordinate with the wing to take off. Actuator 75 is prior art in this technical field and will not be described in detail here. Each sub-frame is provided with a blade 72, a cover 73, and a drive motor 74. Drive motor 74 is fixedly mounted at the end of the sub-frame. Blade 72 is connected to the output end of drive motor 74. Cover 73 is provided on the top of blade 72 to prevent blade 72 from falling out. The rotation of drive motor 74 drives blade 72, thereby causing the drone to take off.

[0050] A cavity is provided below the center of the wing bracket 71 , and a signal receiver 76 is provided in the cavity. The signal receiver 76 is used to receive remote control signals to control the UAV.

[0051] The camera assembly 8 includes a camera 81 and a protective cover 82. The protective cover 82 is arranged on the outside of the camera 81 to play a protective role. The situation at the fire scene can be observed through the camera 81 and transmitted to the cloud.

[0052] A through slot 11 is provided at the upper tail portion of the drone body 1 , a long rod 12 is provided in the through slot 11 , and a hanging ring 13 is provided on the long rod 12 .

[0053] During specific use, first load the fire bomb, rotate and remove all the rotating covers 65, then remove the top cover 64, fill the fire bomb, and the fire bomb enters the barrel 3 along the medicine inlet through the channel composed of multiple fixed rods 61. After loading is completed, the top cover 64 and the rotating cover 65 are screwed back and installed. The drone is controlled to reach the fire scene, and the rocking motor 46 is started to drive the cam 42 to rotate. Through the transmission of the rocker 45, the rotation drives the embolism 43 to move back and forth, releasing the gas in the gas tank into the small chamber of the barrel 3. As the cam 42 rotates, the plug 41 is further pushed up and down, so that the air inlet between the plug 41 and the barrel 3 is opened, the gas is released, and the fire bomb is ejected. During use, the situation at the fire scene can be observed through the camera 81.

[0054] Therefore, the present invention adopts the above-mentioned new dual-link refrigerant fire-fighting drone with an integrated magazine, which saves the time of loading ammunition at the fire scene, flexibly selects the type of ammunition according to different fires, and improves the fire-fighting efficiency; it uses a magnetic buckle design, which is flexible to rotate, tightly fits, and convenient to disassemble and replace the gas tank.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
