Description

TECHNICAL FIELD

[0001] The present application relates to the field of special operation unmanned aerial vehicle and fluid delivery technology, and particularly relates to an integrated flight water pump system capable of realizing large-flow, long-time aerial mobile water delivery operation and landing on water surface to stably float and take water. BACKGROUND

[0002] In the field of fire fighting in high-rise buildings, forest fire fighting and fire fighting in chemical industry parks and the like, the existing technology faces the core bottleneck of continuous large-flow water supply. The physical upper limit exists in the operation height and range of traditional equipment such as a ladder fire engine, and the equipment is limited by roads and terrain. The currently used fire-fighting unmanned aerial vehicle mostly belongs to the mode of carrying a liquid tank, and has the fundamental defects of limited liquid carrying capacity and short operation time, and needs frequent return for liquid supplement, and cannot realize continuous large-flow water supply. In addition, although there is an attempt of unmanned aerial vehicle hanging a water pipe for water delivery, the unmanned aerial vehicle needs to be continuously suspended in the air, and has the problems of high energy consumption and poor stability, and it is difficult to efficiently take water from an open water source such as a lake or a pond. Therefore, a new type of aerial fluid delivery equipment capable of overcoming the above defects and having high mobility, continuous operation capability and open water source utilization capability is urgently needed. SUMMARY

[0003] Technical problem to be solved The technical problem to be solved by the present application is to overcome the deficiencies of the existing aerial fire fighting / water delivery equipment in poor continuous operation capability, high energy consumption and low water source utilization efficiency in a harsh and complex environment, to provide a flight water pump system capable of supporting large-flow, long-time continuous water supply operation, and supporting multiple collaborative operations to cope with the water supply demand of super-large and complex scenes.

[0004] Technical scheme A water surface floating type flight water pump system for large-flow long-time operation, comprising: A multi-rotor flight platform: providing flight and aerial mobility capability of the system.

[0005] A buoyancy stabilizing device: fixedly arranged at the bottom of the multi-rotor flight platform, so that the system can stably land on the water surface and float.

[0006] A large-flow water pump module: installed below the buoyancy stabilizing device, with an inlet below the water surface, and adapted to 220-380V mains power supply or vehicle-mounted generator power supply.

[0007] A high-strength flexible water delivery pipeline: using a general large-diameter fire hose connected to the water pump outlet for long-distance water delivery.

[0008] An intelligent control system: coordinating and controlling the flight attitude and water pump operation of a single device, and supporting networked control of multiple devices, distribution of water supply area and flow.

[0009] Traffic Calculation Method The system flow rate is calculated as **70%** of the pump's rated flow rate. This value takes into account factors such as water source impurities clogging the filter screen, pipeline pressure loss, and power supply voltage fluctuations, which contribute to efficiency degradation during actual operation.

[0010] Calculation formula: Actual water flow rate per unit = Rated flow rate of water pump × 70% Formula for calculating the flow rate of multiple coordinated units: Total actual water delivery flow rate = Actual water delivery flow rate per unit × Number of coordinated units Application example: If the rated flow of a single water pump is 100 m³ / h, then the actual continuous water delivery flow of a single pump is 70 m³ / h; when 5 devices work together, the total actual water delivery flow can reach 350 m³ / h, which can meet the water supply needs for fighting ultra-large fires.

[0011] Beneficial effects It achieves continuous water supply with high flow rate: By adopting the floating water intake mode, it breaks through the limitation of the liquid capacity of drones, and can use high-power water pumps to directly draw water from open water sources with high flow rate, and reduce water delivery resistance with large-diameter fire hoses; multiple units working together can further increase the total water supply flow rate to cope with ultra-large fire scenarios.

[0012] It achieves an ultra-long operating time: when the system lands on the water surface for operation, the flight platform does not need to provide hovering lift, which greatly reduces energy consumption and extends the continuous operation time by several times; at the same time, it is compatible with a wide voltage power supply of 220-380V to ensure flexible power supply in field and urban scenarios.

[0013] Excellent mobility and deployment capabilities: Unrestricted by terrain or roads, it can quickly fly to and utilize natural water sources that are inaccessible to fire trucks; multiple units can be deployed at different water sources or different areas of the same water source, improving water supply flexibility and redundancy.

[0014] The system boasts high compatibility and task flexibility: it can operate independently, serve as an "aerial extension arm" for existing firefighting forces, and allow multiple units to network and coordinate operations; its application scenarios cover urban firefighting, forest fire prevention, flood drainage, and emergency water supply.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1: Independent Open Water Source Intake Operation Mode As shown in Figure 3, this system can operate completely independently in scenarios lacking fixed water supply facilities, such as in the wild or forests. The flying water pump unit flies over an open water source (such as a pond or river) and then lands on the water surface. Its bottom buoyancy stabilization device provides sufficient buoyancy to keep the entire system stable. Connecting the tethered cable to a 220-380V vehicle-mounted generator and starting the pump allows for direct water pumping from the open water source, which is then delivered to fire trucks or distant target locations via large-diameter fire hoses. The actual water flow rate is calculated at 70% of the pump's rated flow rate, ensuring a stable and controllable water supply.

[0023] Example 2: Structural Details of the Flight Water Pump Unit Figure 4 illustrates two specific structural implementations. The buoyancy stabilization device is a platform composed of multiple independent floats, with the pump module fixed beneath it. This design provides excellent buoyancy and water surface stability. The pump outlet is compatible with quick-connect fittings for universal large-diameter fire hoses, enabling rapid assembly and disassembly of the pipeline and improving emergency operation efficiency.

[0024] Example 3: Multi-device collaborative operation mode For complex scenarios such as large-scale forest fires and fires covering the entire chemical industrial park, multiple mobile water pump systems can be networked and operated collaboratively.

[0025] The intelligent control system plans the water source area in a unified manner, and deploys multiple devices at different water intake points of the same open water source, or at multiple nearby water sources, to avoid the problems of water level drop and impurity accumulation caused by water intake in a single area.

[0026] Each piece of equipment independently completes the water surface landing, water intake, and water delivery operations, and delivers water to designated collection points or directly to different fire extinguishing areas through large-diameter fire hoses.

[0027] The intelligent control system monitors the flow rate and water pressure data of each device in real time, dynamically allocates water supply tasks, and ensures that the total water supply flow meets the fire extinguishing needs. When a single device fails, the system automatically allocates its water supply task to the remaining devices to ensure uninterrupted water supply.
