Abstract
Description
Technical Field
[0001] This invention belongs to the field of forest fire emergency equipment technology, specifically relating to a water-pumping firefighting drone that can be airdropped and deployed by an aerial carrier, is suitable for operations in confined water sources, and can achieve remote, one-time laying of water pipelines. This device is particularly suitable for emergency rescue scenarios in mountainous forest fires with complex terrain and limited nearby water sources, including typical mountainous forest areas such as the Ailao Mountains in Yunnan and the mountainous regions of Chongqing. Background Technology
[0002] In recent years, forest fires have occurred frequently in mountainous areas of my country. In rescue operations during forest fires in regions such as the Ailao Mountains in Yunnan and the mountainous areas of Chongqing, traditional firefighting equipment has proven significantly inadequate in dealing with such complex terrain conditions. Specifically, in the Ailao Mountains fire rescue case in Yunnan, although a small reservoir existed approximately 1 kilometer from the fire line, its limited area prevented firefighting helicopters from safely landing to collect water. Only hovering water collection was possible, which suffers from limited water volume per trip, low efficiency in round-trip operations, and high operational risks. At the Chongqing mountain forest fire rescue site, due to steep terrain, complex road conditions, and dense vegetation, large fire trucks could not pass, and conventional fire hoses were difficult to lay effectively by hand. Rescue operations primarily relied on personnel using motorcycles to transport water. This operational mode not only resulted in low water supply efficiency but also required rescue personnel to enter high-risk areas surrounding the fire, facing significant safety risks. Existing technologies lack a dedicated water-pumping and fire-fighting device capable of being directly air-dropped to narrow water surfaces, floating stably on the water, and remotely and disposablely laying water hoses and cables. Most fire-fighting drones currently on the market only possess aerial reconnaissance or fire-extinguishing bomb delivery capabilities, unable to perform water-pumping operations or remote pipeline laying. Some water-pumping equipment suitable for water surfaces requires manual transport to the water source, making it difficult to adapt to the complex terrain of mountainous areas. A few fire-fighting devices with air-drop potential lack effective buffering and attitude adjustment structures, resulting in susceptibility to damage upon landing and unstable floating. Furthermore, they lack a disposable pipeline laying design, still requiring manual assistance for pipeline installation, thus failing to fundamentally solve the core technical problems of "difficulty in utilizing narrow water sources, difficulty in laying pipelines in mountainous areas, and high risks to personnel." Based on this technical background, this invention proposes a highly targeted and integrated air-droppable mountain forest fire-fighting and water-pumping drone, aiming to fill the existing technological gap and effectively improve the efficiency and safety of emergency rescue for mountain forest fires. Summary of the Invention
[0003] Purpose of the invention To address the technical shortcomings of existing mountain forest fire fighting equipment, this invention aims to provide an airdroppable mountain forest fire pumping drone. This drone features airdrop descent capability, adaptive attitude adjustment, stable water surface floating capability, long-range continuous pumping capability, and one-time long-range water pipeline laying capability. This invention is specifically designed for typical mountain forest fire scenarios such as the Ailao Mountains in Yunnan and the mountains of Chongqing, to solve the core technical problems existing in current technologies. Core technical issues and solutions This invention addresses three core technical problems in mountain forest fire fighting operations and proposes systematic technical solutions: Airdrops are easily damaged when they fall into water. To address the technical problem of potential equipment damage due to impact during airdrops, this invention employs a dual design combining an "active descent mechanism" and a "passive buffer structure" to ensure the safety of the airdrop upon landing. Active descent mechanism: The main body of the drone is equipped with four sets of rotors. After being airdropped from the carrier aircraft, the four sets of rotors immediately start, and their rotation speed is precisely controlled by the flight control system to achieve a controllable deceleration descent process, avoiding free fall motion, thereby significantly reducing the initial speed when landing in the water. Passive buffer structure: The bottom floating platform adopts a lotus-shaped inverted cone-shaped sealed chamber structure and is made of a buffer composite material with elastic properties. Combined with its streamlined shape design, it can effectively absorb and disperse the impact energy when falling into the water, protecting the internal precision equipment. Center of gravity optimization design: The overall design ensures that the center of gravity is lower than the center of buoyancy, and with the specific structural form of the floating platform, the drone can quickly achieve automatic stabilization after entering the water, avoiding tipping or overturning, and further reducing the risk of equipment damage caused by impact. Unstable floating posture on the water surface To ensure the operational stability of UAVs in complex aquatic environments, this invention utilizes a collaborative design of an adaptive attitude adjustment mechanism and a biomimetic buoyancy structure to guarantee stable floating. Attitude adjustment mechanism: A universal linkage adjustment mechanism consisting of an adjustment base, an adjustment seat, and an adjustment ball head can achieve adaptive attitude adjustment of the fuselage within a range of ±5°. When encountering unilateral water flow or the influence of wind and waves, this mechanism can automatically fine-tune the fuselage angle to keep the fuselage in a horizontal position. Stable buoyancy structure: The floating platform adopts an inverted frustum-shaped, lotus-pod-like sealed structure that is larger at the top and smaller at the bottom. This structure provides a large water surface contact area and uniformly distributed buoyancy, giving it strong resistance to wind and waves, thus enabling stable floating in complex aquatic environments. Problems of tension damage during remote pipeline laying To prevent equipment from being damaged by tensile forces during the long-distance pipeline laying process, this invention adopts a technical strategy that combines "cooperative laying operation" with "tensile material design". Collaborative operation mode: When the carrier aircraft flies along the planned path from the water source to the fire site to lay pipelines, the UAV floats on the water surface and maintains its relative position with the carrier aircraft through its own rotor power system, rather than being forcibly dragged by the carrier aircraft, thereby greatly reducing the tensile load on the fuselage. Material tensile properties: The water supply pipeline uses disposable lightweight high-strength fire hoses, and the power supply cable uses waterproof and flame-retardant high-strength signal cable. Both have excellent tensile strength and flexibility, and can withstand the tension generated during long-distance laying. Connection disconnection protection: After the water delivery operation is completed, the UAV can actively disconnect from the water pipeline and power cable and return to its home using its own rotor power system, avoiding overload damage caused by long-term stress. Overall structure The airdroppable mountain forest fire-fighting and water-pumping drone provided by this invention comprises, from top to bottom, the following components: drone body (1), adjustable base (2), battery system (3), adjustable seat (10), adjustable ball head (11), floating platform (7), and water pump device (4). It also includes a filter assembly (5), water delivery pipeline (6), power supply cable (9), and camera monitoring device (8). The entire drone adopts an inverted truncated cone structure, with the floating platform (7) being a lotus-shaped sealed cabin structure. All components work together to achieve integrated functions including airdrop, slow descent, floating, water pumping, remote pipeline laying, and autonomous return. Specific structure and function of each component The main body of the drone (1): Located at the top of the entire aircraft, it is equipped with four sets of rotor mechanisms, which provide the power support required for the drone's airdrop descent, flight control, hovering, and autonomous return. Its flight control system can precisely control the rotational speed parameters of each rotor mechanism, realize precise adjustment of descent speed and real-time adjustment of the aircraft's attitude, ensure the stability of the airdrop process and the safety of landing in the water, and avoid damage to the equipment due to impact. Adjustment base (2), adjustment seat (10), and adjustment ball head (11): The adjustment base (2) is fixedly connected to the lower part of the UAV body (1). The adjustment seat (10) and the adjustment ball head (11) together form an angle adjustment mechanism, wherein the adjustment ball head (11) is connected to the floating platform (7). This mechanism can achieve adaptive attitude adjustment within ±5° of the fuselage, and can maintain the stability of the whole aircraft in various operating states such as airdrop, water landing and floating, effectively preventing the fuselage from tilting or overturning, thereby improving the stability of the flight and operation process. Battery system (3): It adopts a sealed waterproof battery structure and is fixedly installed below the adjustment base (2). This battery system provides a stable power supply for all electrical equipment such as the UAV's rotor mechanism, flight control system, water pump device (4), and camera monitoring device (8). Its sealing performance meets the environmental requirements for long-term underwater operation, ensuring that there is no risk of water ingress when the equipment is operating on the water surface. Floating Platform (7): As the main support and floating structure of the whole machine, it adopts an inverted frustum-shaped lotus-shaped sealing structure with a larger top and a smaller bottom, and is made of high-strength waterproof composite material. During the airdrop into the water, its special structural shape can play a buffering and vibration reduction role, absorb impact energy, and protect the internal equipment. After entering the water, thanks to its optimized center of gravity and center of buoyancy design and evenly distributed buoyancy characteristics, it can achieve stable floating in various narrow water source environments such as reservoirs and ponds, effectively resisting the risk of capsizing and sinking, and adapting to complex water surface operation environments. Water pump device (4): It adopts a submersible pump structure and is fixedly installed at the center of the floating platform (7). After entering the water, it can directly draw water from the source below to provide power support for remote water delivery operations. This water pump device is suitable for long-term continuous underwater operation and can realize the function of continuous water supply from the water source to the fire site. Filter assembly (5): Fixedly installed at the inlet of the water pump device (4), used to filter out mud, sand particles, debris and floating matter in the water, preventing these impurities from clogging the water inlet channel of the water pump device (4), thereby ensuring that the pumping system can work continuously and reliably, and avoiding equipment failure caused by blockage. Water supply pipeline (6) and power supply cable (9): The water supply pipeline (6) is a disposable lightweight fire hose, and the power supply cable (9) is a waterproof and flame-retardant power supply and signal transmission cable. The two can be bundled together and stored on the side of the main body of the drone (1). During the laying operation, the carrier aircraft tows it in the air and releases it synchronously along the planned path from the water source to the fire front, thereby quickly forming a remote water supply and power supply channel. Considering that forest fires often last for weeks or months, the terrain at the fire site is complex, and the subsequent cleanup is difficult, the water supply pipeline (6) and power supply cable (9) do not need to be recycled after use. This design not only significantly reduces the difficulty of laying and recycling pipelines in mountainous environments, but also avoids the additional manpower and material costs incurred during the recycling process, further optimizing the overall cost-effectiveness of rescue operations. Video monitoring device (8): The whole machine is equipped with multiple video monitoring devices (8), which are installed around the main body of the UAV (1) and on the side of the floating platform (7). These video monitoring devices are used to collect video information such as the UAV's landing status, floating attitude on the water surface, surrounding environment of the operation, and pipeline connection status in real time, and transmit the video signals to the ground control terminal, thereby significantly improving the intuitiveness of operation and the visibility of the operation process, and ensuring the safety of operation. Manufacturing and assembly processes To ensure reliable production of this invention, its manufacturing and assembly processes are as follows: Shell molding process: The floating platform (7) (i.e., the lotus-shaped sealed cabin structure) is made of high-strength waterproof composite material and formed into an inverted truncated cone structure with a larger top and smaller bottom through injection molding or rotational molding. This process ensures the overall sealing performance of the shell without any splicing gaps, thereby guaranteeing its buoyancy and water-falling buffer performance. After molding, strict waterproof performance testing is required to ensure that there is no leakage. Adjustment mechanism processing technology: The adjustment base (2) and adjustment seat (10) are made of aluminum alloy and manufactured by CNC cutting process to ensure structural dimensional accuracy. The adjustment ball head (11) is a precision universal ball head structure, manufactured by CNC lathe processing technology, and the surface needs to be treated with anti-rust process. Then, the adjustment ball head (11) and adjustment seat (10) are assembled by interference fit to ensure the flexibility of angle adjustment and the stability of the connection structure, and finally realize the free adjustment function within the range of ±5°. Sealing and waterproofing processes: The battery system (3) installation compartment and all circuit interface locations are sealed with silicone sealant rings combined with waterproof glue to completely prevent water ingress. The water pump device (4) uses commercially available, mature waterproof submersible pumps and is directly assembled in a standardized manner. All cable joints and pipeline interfaces must be strictly waterproofed and sealed. The above process measures together ensure that the whole machine has excellent waterproof performance and meets the environmental requirements for long-term underwater operation. Overall assembly process: The main body (1) of the drone is fixedly connected to the adjustment base (2) with high-strength bolts to ensure that the connection structure is firm and reliable. Install the sealed waterproof battery system (3) into the battery compartment below the adjusting base (2), seal and lock it, and complete the connection of all electrical circuits. The adjusting seat (10), adjusting ball head (11) and floating platform (7) are coaxially assembled to ensure that the angle adjustment process is smooth and unobstructed. Install the water pump device (4) into the reserved installation hole in the center of the floating platform (7), and install the filter assembly (5) at the water inlet of the water pump device (4) to complete the connection of the relevant pipeline system. Camera monitoring devices (8) are installed around the main body of the drone (1) and on the side of the floating platform (7). After the wiring work is completed, all line interfaces are waterproofed. The water supply pipeline (6) and the power supply cable (9) are bundled together and their ends are connected to the outlet and power supply interface of the water pump device (4) to ensure reliable connection. A comprehensive functional test is conducted on the entire machine, including flight attitude testing, rotor speed control testing, water pumping function testing, and waterproof performance testing. Once the test is passed, the machine can be delivered for use. Material selection scheme: Structural components materials: The main body (1), adjustment base (2), adjustment seat (10) and other structural components of the UAV can be made of carbon fiber composite materials, aluminum alloy materials or high-strength engineering plastic materials to take into account the technical requirements of lightweight design and structural strength. Sealing materials: Silicone, waterproof rubber and other sealing materials are used to ensure the sealing performance requirements of each connection point. Water supply pipeline materials: Lightweight, high-strength disposable fire hoses should be selected, which must have good tensile strength and waterproof performance. Cable materials: Waterproof and flame-retardant power supply and signal transmission cable materials should be selected, and the materials should have high strength and anti-aging properties. This process is mature and reliable. The required materials and processing equipment are all existing conventional industrial equipment. Those skilled in the art can complete the manufacturing and assembly of the whole machine by following the above process. No special equipment or specialized technology is required. It has good practicality and manufacturability. Working principle The drone of this invention operates according to the following workflow: Airdrop deployment phase: The drone is transported by a fire-fighting aircraft to a small water source (such as a reservoir or pond) near the fire site. Upon arrival at the designated drop point, the airdrop procedure is initiated, separating the drone from the carrier aircraft. Slow descent phase: After the UAV detaches from the carrier aircraft, its four rotor mechanisms immediately activate. The flight control system precisely controls the rotational speed parameters of each rotor mechanism, enabling the UAV to achieve a controllable slow descent process and finally land smoothly on the water surface. The structure of the floating platform (7) can effectively buffer the impact of falling into the water, and at the same time, it achieves automatic stabilization after entering the water by relying on its own structural design. At this time, the attitude adjustment mechanism starts to work, finely adjusting the fuselage angle parameters to maintain the fuselage in a horizontal state. Remote pipeline laying phase: The carrier aircraft flies along the predetermined planned path from the water source to the fire front. During this process, the water supply pipeline (6) and power supply cable (9) bundled and stored on the side of the drone are simultaneously dragged and released, thereby quickly completing the remote water supply pipeline laying operation from the water source to the fire site. Water pumping and supply stage: Connect the end of the laid water pipeline (6) to the water inlet of the fire truck or other fire extinguishing equipment near the fire scene, and connect the power supply cable (9) to the power supply. Start the water pump device (4), and the water pump draws clean water that has been filtered through the filter assembly (5) and continuously supplies water to the fire truck or front-line fire extinguishing equipment through the water pipeline (6) to form a stable long-distance water supply link. Recovery Decision Phase: After the firefighting operation is completed, the drone can initiate a separation procedure through its flight control system to actively disconnect from the water supply pipeline (6) and power supply cable (9). Subsequently, the drone restarts its rotor mechanism, autonomously ascends, and returns to the preset recovery point. Considering the sporadic nature of forest fires and the technical condition of equipment after prolonged high-load operation, rescue commanders can comprehensively assess the difficulty of on-site recovery operations, the cost of recovery, and the potential value of equipment repair and reuse, and flexibly choose to discard the drone on-site or organize professional forces to salvage and recover it after the fire is completely extinguished. This flexible recovery decision mechanism helps optimize the overall rescue cost structure and avoids the potential safety risks of reusing equipment after use in the harsh environment of a fire. Beneficial effects Compared with existing technical solutions, the present invention has the following significant advantages: Highly targeted to specific scenarios: It is specifically designed for forest fire scenarios with complex terrain features, such as the Ailao Mountains in Yunnan and the mountainous areas of Chongqing, where the nearest water sources are mostly small bodies of water. It precisely solves the core technical problems of existing equipment, such as "difficulty in utilizing small water sources, difficulty in water transport operations in mountainous areas, and high risk of personnel transporting water". High airdrop safety: The dual protection design, which combines a quadcopter active controllable descent mechanism with a lotus-shaped sealed cabin passive buffer structure, effectively ensures the safety of the airdrop process and significantly reduces the risk of structural damage to the equipment, resulting in high equipment reliability. Excellent floating stability: Through the collaborative design of the adaptive attitude adjustment mechanism and the lotus-shaped wide-body floating platform, the UAV has excellent wind and wave resistance and can maintain a stable floating state under complex water surface environment conditions, effectively preventing capsizing or sinking. High deployment efficiency: Utilizing a combined airdrop and aerial coordinated pipeline laying operation mode, a long-range water supply channel can be rapidly established from remote water sources to the fire site within minutes. Its continuous water supply capacity far exceeds that of the traditional airdrop operation mode, significantly improving firefighting efficiency. High terrain adaptability: The entire deployment and operation process is basically completed through aerial operations, completely unrestricted by complex terrain conditions such as mountains, steep slopes, dense forests, and loose rocks. Rescue personnel do not need to risk entering the vicinity of the fire site to lay pipelines, significantly reducing the risk to their lives. Cost-effective and highly practical: The water supply pipeline and power supply cable adopt a disposable design, eliminating the need for recycling and maintenance after use. The material costs are significantly lower than the overall costs of organizing manpower for laying and recycling, or using reusable equipment. Furthermore, the manufacturing process of this invention is mature and reliable, easily enabling mass production and demonstrating excellent practical performance. Safe and reliable operation: The drone is equipped with cameras located in multiple positions on the fuselage to provide visual monitoring of the entire operation process. Combined with the adaptive adjustment function of the fuselage attitude and the excellent waterproof sealing performance of the whole machine, the drone can adapt to harsh rescue environment conditions and ensure the safety and stability of the operation process.

Detailed Implementation
[0005] To make the technical solutions and advantages of the present invention clearer, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be particularly noted that the following embodiments are only used to explain the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Example 1 This embodiment demonstrates the specific application of the UAV of the present invention in an emergency rescue scenario for forest fires in the Ailao Mountains region of Yunnan Province. Airdrop deployment operation: The fire-fighting aircraft carrying this drone flew to the airspace above a small reservoir near the Ailao Mountain fire site. Upon reaching the designated drop coordinates, the airdrop procedure was initiated, and the drone separated from the carrier aircraft. After separation, the drone's four rotor mechanisms immediately started operating, adjusting the rotation speed parameters under the precise control of the flight control system to achieve a controlled, slow descent, ultimately landing smoothly on the reservoir surface. Automatic attitude stabilization: During the UAV's descent into the water, the floating platform (7) structure at its bottom effectively buffers the impact of the water flow. At the same time, the universal adjustment mechanism, consisting of the adjusting ball head (11) and the adjusting seat (10), works together to automatically fine-tune the fuselage angle parameters, ensuring that the UAV maintains a horizontal floating attitude on the water surface and avoiding tilting. Remote pipeline laying operation: The carrier aircraft then flies along the planned operation route from the reservoir to the fire front. During the flight, the water supply pipeline (6) and power supply cable (9) that are pre-tied and stored on the side of the drone are simultaneously dragged and released, thereby quickly completing the water supply pipeline laying operation from the water source to the fire. Water pumping and supply operation: Ground rescue personnel connect the end of the laid water pipeline (6) to the water inlet of the fire truck near the fire scene, and connect the power cable (9) to the mobile power supply device or generator set. Then, the water pump device (4) is remotely started. The water pump draws water from the reservoir through the filter component (5) at its water inlet and continuously supplies water to the fire truck through the water pipeline (6), establishing a stable remote water supply operation link. Operation process monitoring: Throughout the operation, ground control personnel can observe the water attitude of the UAV, pipeline docking operation and surrounding environmental conditions in real time through multiple sets of camera monitoring devices (8) arranged around the main body of the UAV (1) and the side of the floating platform (7), ensuring the safety and stability of the entire operation process. Recovery Plan Decision: When the firefighting operation is basically completed and the remote water supply operation is no longer needed, the UAV initiates the separation procedure through the flight control system to cut off the connection with the water supply pipeline (6) and the power supply cable (9). Subsequently, the UAV restarts its rotor mechanism, autonomously takes off, and flies back to the preset rendezvous point. The on-site rescue command comprehensively evaluates the complexity of the terrain in the fire area, the difficulty and cost of the equipment recovery operation, and the technical condition of the UAV after a long period of high-intensity operation, and decides whether to discard it on-site or organize professional rescue forces to salvage and recover it after the fire is completely extinguished. This flexible decision-making mechanism adapts to the actual needs and cost-effectiveness considerations of fire emergency rescue scenarios. In this application scenario, the UAV of the present invention successfully solved the technical challenges of forest fire fighting in the Ailao Mountains region caused by complex terrain and limited water resources. This device eliminates the need for rescue personnel to risk entering the mountains to lay pipelines, enabling the rapid establishment of a remote water supply system. This significantly improves the efficiency of rescue operations while greatly reducing the operational risks faced by rescue personnel, fully demonstrating the practicality and scenario-specificity of the invention.
