Description

Technical Field

[0001] This invention relates to the field of meteorological unmanned aerial vehicle (UAV) technology, specifically to a rotary-wing meteorological UAV and its marine recovery method. Background Technology

[0002] A weather drone is an unmanned aerial vehicle (UAV) system used for meteorological observation and research, capable of collecting atmospheric and environmental data. Weather drones typically operate in two modes: fixed-wing and rotary-wing. Rotary-wing UAVs can take off and land vertically and fly at low altitudes. They are primarily used for low-altitude meteorological observation, such as measuring wind speed and air pressure in tropical cyclones. When operating at sea, weather drones require appropriate recovery systems to ensure they can be recovered upon return after collecting meteorological data, preventing them from crashing into the ocean.

[0003] A search revealed that patent publication number CN110654538B discloses a weather detection drone, relating to the field of weather detection technology. The drone includes a body with a mounting plate fixedly installed on its upper surface and a battery compartment fixedly installed on its lower surface. Four wings are evenly distributed in a circular array on the outer side of the body. A weather detector is fixedly installed on the top of the mounting plate, and a fixing plate is fixedly installed on the bottom of the weather detector. A fixing mechanism is installed at the connection between the fixing plate and the mounting plate. This invention has a reasonable structure, is simple to operate, and can automatically open and close the compartment cover, facilitating battery installation. It not only saves manpower but also effectively improves work efficiency, making it highly practical. The fixing mechanism allows for quick installation and removal of the weather detector, facilitating maintenance and replacement. Furthermore, the weather detector can be removed when not in use, allowing the drone to operate independently.

[0004] Although the aforementioned drone can achieve the purpose of rapid installation and disassembly of weather detectors, it lacks corresponding anti-capsulation and anti-seawater erosion protection devices when operating in water. When the drone runs out of power and falls into the sea for recovery, it is very easy for the motherboard and motor to leak water, resulting in damage to the aircraft. Secondly, for more diverse and changeable external conditions, such as strong winds and waves, weather drones cannot effectively avoid risks and protect themselves. Therefore, this invention proposes a rotary-wing weather drone and its marine recovery method. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rotary-wing weather drone and its marine recovery method, which solves the problem that existing weather drones cannot effectively avoid risks and protect themselves.

[0046] A method for recovering a rotary-wing weather drone at sea includes the following steps:

[0047] Step 1: After the weather drone flies to the designated sea area, the protective shell on top opens, and then the electric telescopic boom is activated to extend the mounting platform and the measurement components installed on top of it into the main cabin, so as to detect and collect meteorological data. At the same time, in order to cope with some complex terrain along the coast and meet the needs of low-altitude detection, the length of the adjustable wings is adjusted to meet the operational needs of the weather drone.

At the same time, the power supply module will provide power support for the operation of the drone.

[0049] Step 3: When the remaining battery power is low, the actuator module on the drone will retract the measuring components into the main cabin and drive the four protective shells on the top to close, sealing the weather drone and preventing seawater from entering the main cabin. At the same time, when the bottom of the main cabin touches the sea surface, the liquid level sensor unit will detect and send a signal, and the controller will start the inflation unit to inflate the safety airbag at the bottom of the main cabin. The airbag will then be released through the airbag release unit to pop the safety airbag out of the main cabin, ensuring that the drone can stay on the sea surface.

[0050] Step 4: The recovered vessel then moves to the sea area near the drone using the recovery positioning module. The real-time images on the visual sensor unit quickly locate the position between the drone and the vessel. When recovering at night, the sound and light alarm unit can emit sound and light signals to help the personnel on the vessel quickly locate the drone's position.

[0051] This invention provides a rotary-wing weather drone and its marine recovery method. It has the following beneficial effects:

[0052] 1. This invention uses a hydrophobic coating to waterproof the drone, which enhances the drone's corrosion resistance. It also seals the drone's body, greatly reducing its weight and size, reducing its windward surface area, and achieving better endurance.

[0053] 2. Through the cooperation between the main cabin, electric telescopic rod, mounting platform, sensor bushing, measurement components, protective shell and actuator module, this invention can avoid strong winds or waves and reduce the risk of damage to the UAV's airframe structure. Secondly, the four protective blades can be completely closed, which also completes the waterproofing treatment to a certain extent, reducing the risk of the exposed measurement module being affected by seawater, rainfall and other factors during operation.

[0054] 3. Through the cooperation of the actuator module, the cabin emergency protection module and the recovery positioning module, this invention can ensure that the UAV can safely remain on the sea surface during recovery in complex marine environments, while also making it easier for recovery personnel to locate and recover the UAV.

It can also be used to identify and avoid obstacles, ensuring safe flight and successful recovery of the drone.

[0106] A lidar positioning unit is used to locate unmanned aerial vehicles (UAVs) using lidar. It achieves real-time monitoring and control of the UAV by utilizing lidar for high-precision positioning. Lidar is a ranging and sensing device that calculates distance and orientation by emitting a laser beam and receiving the reflected laser signal. Compared to traditional positioning technologies, lidar positioning units offer higher accuracy and reliability, especially in complex marine environments.

[0107] During operation, the lidar positioning unit first scans the drone to create a 3D point cloud of its surrounding environment. By processing and analyzing this data, information such as the drone's position, speed, and attitude can be obtained. This information is then compared with pre-set parameters to achieve precise control of the drone. Furthermore, the lidar positioning unit can monitor the drone's status in real time and make adjustments accordingly, ensuring the drone's stability and safety during flight.

[0108] The audible and visual alarm unit is another key component of the recovery and positioning module.
