[0025] The frame 103 serves as a support structure, used to fix key components such as the motor, electronic speed controller 202, and battery, ensuring overall structural stability. The housing 1 is made of high-density polyethylene (HDPE) and covers the outside of the frame 103. The device dimensions are ≥1100mm×1150mm×270mm, with a tolerance of ±10.5mm. It forms a closed protective structure with a dedicated cover 104, protecting internal components from water splashes and impact damage. The overall structure is compact, lightweight, and has strong casting stability. The power components include four brushless motors 2, four electronic speed controllers 202, four 18-inch composite carbon fiber propellers 201, and two underwater thrusters 4. The brushless motors 2 and propellers 201 are one-to-one, and the electronic speed controllers 202 achieve precise speed control. The control system features a single motor with a propeller blade 201 having a maximum pull of ≥5.0kg, providing ample power for the device's flight. The propeller blade 201 has a 4.5-inch pitch, and each blade is equipped with a mesh cover, totaling four covers. These covers, along with the propeller blade protective ring 101, are integrally molded to effectively prevent collisions between the blades and foreign objects, enhancing safety during flight and rescue operations. Two underwater thrusters 4 are symmetrically mounted at the bottom of the casing 1, providing power for the device's surface navigation, enabling a surface speed of 3m / s. The device uses a 58V / 12Ah lithium-ion battery, installed in the middle of the frame 103, providing stable power to all electrical components, including the brushless motor 2, electronic speed controller 202, flight controller, single-axis camera 3, and horn, ensuring the equipment's stability. Continuous operation; a single-axis camera 3 is mounted on the front of the housing 1, with a single-axis movement range of +90° to -90° and a resolution of 720P. The camera can flexibly adjust its shooting angle, acquiring real-time video footage of the rescue scene and transmitting it to the remote controller and command platform. The device's flight controller has a communication range of 1.1 km on water and 10 km at an altitude of 100 m. It is equipped with a 5-inch display screen to show real-time operating parameters. The device integrates one-key takeoff and one-key return functions, automatically triggering an autonomous return procedure when the remote control signal is lost to ensure safe recovery of the equipment. The overall structural design can withstand winds of force 6 and sea state 2, adapting to complex weather and aquatic environments. The built-in speaker is installed inside the housing 1, not protruding from the surface, with a diameter ≤6 cm, and communicates with the flight controller via a wire. The device's power amplifier module is connected to enable voice communication, facilitating rescuers to deliver rescue instructions to drowning victims. During use, a remote control and receiver are required. The receiver is fixed to rack 103 and connects wirelessly to the remote control. The remote control features a real-time battery level display and can simultaneously receive real-time footage from the onboard camera, allowing operators to remotely monitor equipment status and the rescue scene, and precisely control the device's flight and trajectory. The device has a pre-reserved open-source interface integrated into the flight controller, supporting video transmission and fusion video dispatch access. It can seamlessly connect to the mobile command platform resource tree of local provincial and municipal fire and emergency management bureaus. Through this platform, the command center can perform operations such as video retrieval, two-way voice communication, issuing rescue commands, and adjusting equipment parameters.

[0026] In this embodiment of the invention, each blade 201 is made of composite carbon fiber. Two reinforcing rods 102 are provided at the bottom of the housing 1. Four brushless motors 2 are respectively installed at the bottom of the two reinforcing rods 102 and located at the center point of the protective ring 101. The electronic speed controller 202 is embedded inside the reinforcing rods 102. Each blade 201 is installed at the output end of the brushless motor 2. A mesh cover is fixedly installed inside the protective ring 101. The protective ring 101 and the mesh cover are integrally molded, and the mesh cover and the protective ring 101 are on the same horizontal plane. A recess is provided on one side of the bottom of each of the two reinforcing rods 102, and an underwater thruster 4 is fixedly installed inside each recess.

[0027] The flying lifeboat sends commands via remote control, which are transmitted to the flight controller via receiver. The flight controller then sends a signal to the electronic speed controller 202 embedded inside the reinforcing rod 102, precisely adjusting the speed of the brushless motor 2 at the center point of the protective ring 101 at the bottom of the reinforcing rod 102. This drives the composite carbon fiber propeller 201 to rotate, generating sufficient thrust to achieve flight, turning, and other maneuvers. When switching to water navigation mode, the two underwater thrusters 4 embedded in the recess of the reinforcing rod 102 control the equipment's trajectory through speed difference. Simultaneously, the protective ring 101 and the net are integrally molded on the same plane, ensuring both safety and stability. This solution ensures safety during flight and navigation while reducing drag. Leveraging the lightweight and high-strength characteristics of the composite carbon fiber blade 201, combined with the integrated load-bearing design of the reinforcing rod 102 for the motor and ESC, and the optimized integration of the thruster and protective structure, this solution not only improves the equipment's structural compactness, power output stability, and operational safety, effectively preventing component damage and secondary injuries, but also enhances its adaptability to complex waters and harsh environments. It achieves seamless integration of flight and water rescue, significantly improving rescue efficiency and filling the application gap of traditional rescue equipment in complex scenarios.

[0028] Before each rescue, the following checks must be performed: Check that the connection between the frame 103 and the housing 1 is secure, that the cover 104 is tightly closed, and that screws, nuts, propellers 201, and the mesh cover are not loose, damaged, or deformed; check that the wiring of the brushless motor 2, ESC, and underwater thruster 4 is intact and free from short circuits or open circuits; confirm that the lithium-ion battery has sufficient power and the remote control has enough power for operation; test the communication functions of the single-axis camera 3, horn, remote control, and receiver to ensure they are normal, and that the flight controller parameters are stable; after testing, select an open, unobstructed area, free of power lines and trees, as the takeoff point to avoid collisions during flight; operators must operate the equipment within visual range, and are strictly prohibited from operating under the influence of alcohol, ensuring normal reaction and judgment abilities; during operation, fingers must not leave the remote control joystick, maintaining continuous control of the equipment and being prepared to respond to sudden airflow, signal interference, etc.; the equipment's flight altitude is strictly limited to within 100 meters and must not exceed the safe altitude; when operating... If the remote control interface displays a voltage of 50.4V, reaching the low battery alarm threshold, the equipment must be immediately operated to return to base and land to avoid battery depletion and equipment malfunction. During rescue, power on the equipment and trigger the one-button takeoff function via the remote control to quickly fly the flying rescue boat over the rescue site. Use the remote control to view the real-time image from the single-axis camera 3 to accurately locate the drowning victim and adjust the equipment's flight trajectory to land smoothly in the water near the victim. Switch to water navigation mode and use the underwater propulsion device 4 to move the equipment closer to the drowning victim, while simultaneously using the voice command function to guide the victim to grab onto the equipment casing 1 or the dedicated handrail. After confirming the victim is safely attached, operate the equipment to return to shore or proceed to the designated assembly point according to the command center's instructions. After the rescue is completed, power off the equipment, remove the cover 104 to clean and inspect the internal components to ensure normal operation next time. If the remote control signal is lost during the rescue, the equipment will automatically activate the autonomous return function, and the operator must wait at the takeoff point for the equipment to be retrieved.
