Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to an airborne high-pressure fire extinguishing system for UAVs. Background Technology

[0002] In recent years, drone technology has developed rapidly, demonstrating enormous potential in the field of firefighting, especially in scenarios where traditional firefighting methods struggle to quickly and effectively cover high-rise buildings, forest canopies, complex terrain, and initial fires. Using drones for firefighting operations offers significant advantages such as rapid response, high mobility, lack of terrain limitations, and the ability to conduct close-range reconnaissance and operations.

[0003] Currently, the drone firefighting systems used in the firefighting field mainly take the following forms:

[0004] Portable fire extinguishing devices: such as suspended dry powder or gas fire extinguishing canisters, fire extinguishing bombs, etc. Although this method can be deployed quickly, the extinguishing agent capacity is limited, the coverage area of ​​a single deployment is small, it is difficult to deal with fires that require continuous suppression or cover a large area, and it cannot perform precise and continuous spraying. Its suppression effect on high-altitude or concealed fire points is limited, and it is mainly used for rapid intervention in specific scenarios.

[0005] Airborne water tank fire suppression system: Drones carry small water tanks and airborne water pumps to spray water for fire suppression. This method solves the problem of continuous spraying, but due to the limitations of the drone's payload and endurance, the water tank capacity is usually small, resulting in a short continuous spraying time and the need for frequent returns to refill water, which greatly reduces fire suppression efficiency and operational radius. For fires requiring long-term suppression or large-area fires (such as in the initial spread stage), its sustained combat capability is clearly insufficient.

[0006] Tethered power / water supply system: This system provides power or water to the drone via cables. Theoretically, it can solve the problems of endurance and continuous water supply, but the heavy cables greatly limit the drone's flight altitude, maneuverability, and operating range. They are also prone to entanglement in complex urban environments or forests, posing high safety risks and being relatively cumbersome to deploy.

[0007] The main problem with existing technology is that:

[0008] Insufficient sustainability: Whether it is a portable device or a small water tank, the extinguishing agent / water volume is limited, making it difficult to meet the needs of long-term, continuous suppressive water spraying at the fire scene (especially the initial or high-altitude fire points).

[0009] Low operational efficiency: Frequent back-and-forth trips to replenish water or replace fire extinguishing equipment significantly shorten the effective operating time, resulting in low fire extinguishing efficiency.

[0010] Weak ability to respond to high-altitude / initial fires: Traditional firefighting equipment (such as ladder trucks and high-pressure water guns) are limited by height and terrain, making it difficult to quickly and effectively reach initial fire points in high-altitude or complex environments; the shortcomings of existing drone firefighting solutions in terms of sustained suppression capabilities also limit their effectiveness in such scenarios.

[0011] Inconvenient deployment and maintenance: Existing systems are often highly integrated or have complex structures, making them difficult to disassemble and assemble, which is not conducive to rapid deployment, transportation, and on-site maintenance and component replacement.

[0012] Therefore, there is an urgent need to develop a fire-fighting system suitable for drones that can solve the problem of continuous water supply to achieve long-term water spraying operations, effectively extinguish high-altitude and initial fires, and at the same time have the characteristics of convenient operation, easy transportation and maintenance and replacement, so as to give full play to the unique advantages of drones in the field of fire fighting.

The water pipe tee 1530, the tee connector 1540 and the tee plug 1560 are installed together in the second arc surface 15701 of the tee fixing frame 1570, and its displacement is restricted by the tee limiting bosses 15702 set on the left and right. At the same time, two pressure pieces 1520 are used above to fix it on the tee fixing frame 1570. The vertical joint of the water pipe tee 1530 is equipped with a first water hose quick connector 1550.

[0078] The water spray bracket 150 is mounted on the water spray bracket mounting base 1103 at the bottom of the drone body 110 via the second quick-release structure 1510 at its top. The electro-optical pod 120 is mounted on the electro-optical pod mounting base 1101 at the bottom of the drone body 110 via the first quick-release structure 1201 at its top. At the same time, the electro-optical pod electrical plug 1202 of the electro-optical pod 120 is plugged into the electro-optical pod electrical socket 1102 at the bottom of the drone body 110, thereby realizing the mechanical and electrical connection between the electro-optical pod 120 and the water spray bracket 150.

[0079] The strut fixing slots 1404 on the two strut fixing seats 1403 at the rear end of the diagonal strut 140 are fitted onto the diagonal strut fixing platforms 1105 of the diagonal strut fixing seats 1104 symmetrically arranged on the left and right sides of the landing gear of the UAV body 110. At the same time, the plunger pin 1406 at the end of the plunger pin 1405 is inserted into the first round hole 1106 on the diagonal strut fixing platform 1105, and one end of the diagonal strut 140 is fixed to the landing gear of the UAV body 110.

[0080] Open the water pipe fixing seat 1401 on the assembly diagonal brace 140 to expose the water pipe fixing groove 1402.

[0081] The third water pipe connector 13202 at the rear end of the second water pipe 1320 is threadedly connected to the tee connector 1540 on the water spray bracket 150. The first water pipe connector 13103 at the rear end of the first water pipe 1310 is threadedly connected to the second water pipe connector 13201 at the front end of the second water pipe 1320.

[0083] At this point, the assembly between the airborne high-pressure fire extinguishing system and the main body of the drone is complete. The disassembly process is the reverse operation. During conventional packaging and transportation, all unit modules can be disassembled and assembled simply by hand. It features a simple structure, convenient operation, and facilitates the transportation, maintenance, and replacement of the drone's airborne high-pressure fire extinguishing system.

[0084] The drone is equipped with a high-pressure fire extinguishing system connected to a stable water source. After a fire breaks out, the drone quickly takes off and uses the visible light and infrared lenses of the electro-optical pod 120 to continuously scan the area near the target to confirm the specific location of the fire. After detecting an anomaly, the electro-optical pod 120 locks the direction angle and coordinates the drone to descend into the target area. After the operator at the rear confirms that there is heat smoke or flames, the high-pressure water pump 220 is activated. The high-pressure water pump 220 pressurizes the ground water source and sends it to the bottom of the drone. The water is then sprayed out from the spray hole 13102 in the middle of the nozzle 13101 through the water pipe tee 1530, the second water pipe 1320 and the first water pipe 1310 until the heat source or flames are eliminated.

[0085] After completing an operation and returning to the ground, the drone can be taken off again after the battery is replaced. It has the advantages of high operational efficiency, long continuous water spraying time, and effective extinguishing of high-altitude or initial fires.
