Description

Technical Field

[0001] This invention relates to the field of hydrogen-powered drone technology, specifically to an AEM fuel cell hydrogen-powered drone designed to prevent crashes. Background Technology

[0002] In the field of drones, the APU (Auxiliary Power Unit), though small in size, plays a crucial, versatile role. When drones perform high-altitude, long-endurance missions, the APU can optimize energy distribution, share the load with the main power system, and extend the overall flight time. This is especially true for reconnaissance drones carrying multiple sets of reconnaissance equipment, as it can prevent the main engine from experiencing performance degradation due to continuous high-load operation.

[0003] The main components of a hydrogen-powered drone are a hydrogen fuel cell stack, a hydrogen storage tank, a power motor, a flight control system, and auxiliary equipment. The hydrogen storage tank is typically made of lightweight composite materials and stores high-pressure gaseous hydrogen. The fuel cell stack converts hydrogen energy into electrical energy to power the motor and flight control system. The power motor drives the propeller to generate thrust. Before use, first check the sealing and pressure of the hydrogen storage tank to ensure there are no leaks, then install it onto the fuselage. Connect the circuits of the fuel cell, motor, and flight control system, and power on the drone to perform a self-check of all parameters. Plan the flight path via the ground station and unlock the motor for a test flight. During the mission, monitor hydrogen consumption and battery status in real time. After completion, gradually reduce thrust and control the drone to return to base. After landing, turn off the power, disassemble the hydrogen storage tank for proper storage, and clean the fuselage components for future use.

[0004] While most high-pressure gaseous hydrogen storage cylinders currently in use have passed basic impact tests, they still face multiple risks in actual drone operation scenarios. When a drone crashes, even if the fuselage's cushioning structure absorbs some of the impact force, the sealing gasket at the hydrogen storage cylinder interface may deform due to instantaneous stress concentration. After long-term use, the rubber material is prone to aging and hardening, leading to a small amount of hydrogen leakage. Furthermore, the high-frequency vibration during high-speed drone flight will subject the cylinder to alternating stress for a long time: the interlayer bonding strength of composite materials will gradually weaken, micro-delamination will occur between the fiber fabric and the resin matrix, and the connection between the metal valve and the cylinder will loosen due to resonance, posing a potential threat to flight safety. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is that although the current mainstream high-pressure gaseous hydrogen storage cylinders have basic impact resistance, they may suffer from hidden dangers such as interface sealing aging and micro-cracks in the cylinder body under conditions such as drone crashes and extreme temperature differences, and may exacerbate material fatigue under high-frequency vibration.

Multiple slots are formed on the side wall of the support rod 3, with equal spacing and the same size between each slot. The bolt 11 on the positioning plate 1 secures the support rod 3. These slots are mostly streamlined and distributed along the axial direction of the rod, eliminating redundant material and reducing overall weight, while also guiding airflow smoothly through the slots and reducing the formation of air vortices. During high-speed flight, the pressure difference is reduced after the airflow is diverted through the slots, reducing wind resistance and mitigating rod vibration, thus improving the drone's attitude stability.

[0034] Reference Figures 1-5 A connecting plate 43 is fixedly installed on one end of the support rod 3 near the positioning plate 1, and the connecting plate 43 and the positioning plate 1 are in close contact with each other.

[0035] Reference Figures 1-5 A telescopic vertical rod 31 is fixedly installed at the bottom end of the support rod 3, and an anti-slip plate is fixedly installed at the bottom end of the vertical rod 31.

A buffer pad 52 is fixedly installed at the connection between the transmission device 5 and the fan blade 51. The vertical rod 31 installed at the bottom end of the support rod 3 ensures the support of the device body, and the anti-slip plate installed on the vertical rod 31 ensures good stability of the UAV during takeoff and ensures safety during takeoff. The buffer pad 52 installed between the fan blade 51 and the transmission device 5 prevents impurities from getting tangled in the fan blade 51 shaft during flight and ensures the normal operation of the device.

[0039] Reference Figures 5-8 A horizontal plate 731 is fixedly installed on the positioning tube 73, and a connection port 732 is opened on the horizontal plate 731. The output end of the hydrogen storage tank 8 is fixedly connected to the connection port 732. A connector 733 is fixedly installed on both ends of the horizontal plate 731, and the connector 733 is controlled by the APU processor 2. The horizontal plate 731 on the positioning tube 73 fixes the position of the hydrogen storage tank 8. When the device is operating, the operator can control the operating status of the connector 733 through the APU processor 2, so that when the device is hit by a collision and the power is insufficient, the APU processor 2 can start the backup power to maintain the operation of the drone and prevent it from falling.

[0040] Reference Figures 6-8 An adjusting cap 721 is rotatably mounted on the outer circumferential surface of the long pipe 72, and multiple evenly arranged anti-slip ridges are fixedly mounted on the outer circumferential surface of the adjusting cap 721.

[0042] Specifically, the solution is as follows: the APU processor 2, mounted on the positioning plate 1, controls the various processing units in the device; the fan blades 51 mounted on the support rod 3 ensure stable power for the UAV; the bolts 11 mounted on the positioning plate 1 secure the support rod 3; the slots on the support rod 3 are mostly streamlined and distributed along the axial direction of the rod, which not only removes redundant materials and reduces overall weight, but also guides airflow smoothly through the slots, reducing the formation of air vortices. During high-speed flight, the pressure difference is reduced after the airflow is diverted through the slots, which reduces wind resistance and also reduces rod vibration, improving the attitude stability of the UAV. The connecting plate 43 mounted on the support rod 3 facilitates the positioning and fixation of the support rod 3, and the controller 4 mounted on the support rod 3 can control the tilt angle of the support rod 3, thereby controlling the UAV's steering to achieve its goal. Furthermore, when the UAV encounters insufficient power supply during flight, the APU processor 2 can control the hydrogen storage tank 8 on the bracket 61 via the circuit board 12 to provide backup energy supply and prevent the UAV from crashing.
