Description

Technical Field

[0001] This utility model relates to the field of marine inspection equipment technology, and in particular to a marine wind power inspection system based on a hydrogen-powered drone. Background Technology

[0002] The hydrogen-powered drone-based offshore wind power inspection system is an innovative solution that utilizes hydrogen fuel cell-powered drones, combined with advanced sensors and artificial intelligence technology, to conduct efficient and safe inspections of offshore wind power equipment. This system achieves long-endurance and environmentally friendly flight capabilities through hydrogen-powered drones, carries multiple sensors to collect real-time wind turbine status data, and uses AI algorithms to analyze the data and generate inspection reports. Its advantages include improved inspection efficiency, reduced human error risks, reduced environmental pollution, and applicability to the inspection needs of offshore wind power and other infrastructure.

[0003] Currently, offshore wind power inspection is generally carried out by drones. However, traditional battery-powered drones have limited endurance, making them unable to perform long-duration operations. Furthermore, due to strong winds at sea, the lightweight design of traditional drones results in significant shaking during inspections, making it difficult to obtain clear and complete real-time images. This leads to misinterpretations of inspection information and affects normal offshore inspection work. Therefore, this invention proposes an offshore wind power inspection system based on a hydrogen-powered drone to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a marine wind power inspection system based on a hydrogen-powered drone.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A marine wind power inspection system based on a hydrogen-powered drone includes a drone body, which comprises a fuselage and wings. A base is fixedly installed on the lower part of the drone body fuselage. The base contains a hydrogen fuel cell, a hydrogen tank, and a reaction chamber. Several guide plates are rotatably connected to the lower periphery of the base, and several connecting blocks corresponding to the guide plates are provided on the lower periphery of the base. The guide plates and connecting blocks are rotatably connected to the lower part of the base. A monitoring camera is fixedly installed on the outer end of the guide plate.

[0007] Preferably, a motor is fixedly installed inside the base, the motor is electrically connected to the internal hydrogen fuel cell, and a gear is fixedly connected to the lower end of the motor output shaft.

[0008] Preferably, the connecting block has a slot corresponding to the guide plate inside, and the slot has a sliding groove at both the top and bottom, and the guide plate has a sliding shaft that slides in the sliding groove.

[0009] Preferably, a plurality of meshing gears are provided on one side of the gear, and a connecting bar is fixed on the lower side of the gears.

[0010] Preferably, a sliding shaft is fixed to the outer end of the linkage bar, and a second sliding groove corresponding to the sliding shaft is provided on the lower side of the connecting block.

[0011] Preferably, a water collection box is provided at each of the four corners of the lower part of the base, the water collection box is connected to the internal reaction chamber of the base, and a water leakage hole is provided on the lower side of the outside of the water collection box.

[0012] Preferably, the main body of the UAV is equipped with several motors corresponding to the wings, and all of the motors are electrically connected to the hydrogen fuel cell in the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a hydrogen fuel cell as a power source, which has high energy density and long endurance, far exceeding that of traditional battery-powered drones. It is suitable for long-term offshore wind power inspection missions. The chemical reaction of the hydrogen fuel cell only produces water and has no harmful emissions, making it particularly suitable for environmentally sensitive offshore wind power inspection missions.

[0015] 2. The main body of this utility model drone is made of lightweight high-strength composite material, which reduces the weight of the fuselage and improves flight efficiency and endurance. The base integrates a hydrogen fuel cell, hydrogen tank and reaction chamber, which is compact and easy to maintain and upgrade.

[0016] 3.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A marine wind power inspection system based on a hydrogen-powered drone includes a drone body 1, which includes a fuselage and wings. A base 2 is fixedly installed on the lower part of the drone body 1. The base 2 contains a hydrogen fuel cell, a hydrogen tank, and a reaction chamber. The chemical reaction between hydrogen and oxygen in the reaction chamber generates electricity, which is stored inside the hydrogen fuel cell. The hydrogen tank is used to store hydrogen, and the hydrogen fuel cell is used to supply power to the drone's drive mechanism. The drone body 1 also includes a power management system, a flight control system, a sensor system, and a communication system to ensure the normal marine wind power inspection work of the hydrogen-powered drone. The drone body 1 is made of lightweight, high-strength composite materials and is equipped with a high-efficiency hydrogen fuel cell stack to ensure long-distance flight capability while reducing environmental impact.

[0024] Furthermore, several guide plates 5 are rotatably connected to the lower periphery of the base 2, and several connecting blocks 6 corresponding to the guide plates 5 are provided on the lower periphery of the base 2. The guide plates 5 and the connecting blocks 6 are rotatably connected to the lower part of the base 2. A monitoring camera 12 is fixedly installed on the outer end of the guide plate 5. The connecting block 6 has a slot 10 corresponding to the guide plate 5 inside. The slot 10 has a sliding groove 11 at both the top and bottom. The guide plate 5 is provided with a sliding shaft 14 that slides in the sliding groove 11. Therefore, when the outer connecting block 6 is rotated open, the inner guide plate 5 slides in the sliding groove 11 due to the sliding of its outer end sliding shaft 14. Yes, the guide vane 5 on one side rotates outward, and the monitoring camera 12 at the outer end of the guide vane 5 rotates outward as well. The outward-extended monitoring camera 12 is more conducive to the inspection of the wind power system and obtains a more detailed and comprehensive real-time picture of the wind power system. At the same time, the structure of the outward-extended guide vane 5, together with the connecting blocks 6 of the four-sided counterweight, can maintain a relatively stable attitude when the drone hovers in the air, which is more conducive to the inspection of the wind power system. The base 2 also includes thermal imagers and environmental monitoring sensors. By adjusting the angle of the guide vane 5, a detailed inspection of key components such as wind turbine towers and blades can be achieved.

[0025] Furthermore, a motor is fixedly installed inside the base 2, and the motor is electrically connected to the internal hydrogen fuel cell. A gear 7 is fixedly connected to the lower end of the motor output shaft. Several meshing gears 9 are arranged around the gear 7, and a connecting bar 8 is fixed to the lower side of the gear 9. A sliding shaft 14 is fixed to the outer end of the connecting bar 8. A sliding groove 13 corresponding to the sliding shaft 14 is opened on the lower side of the connecting block 6. The hydrogen fuel cell supplies electrical energy to the motor inside the base 2. The motor drives the connected gear 7 to rotate. The gear 7 drives the several meshing gears 9 around it to rotate. The gears 9 rotate outward. Through the sliding of the outer end sliding shaft 14 in the sliding groove 13, the connecting block 6 is rotated open.

[0026] Furthermore, water collection boxes 3 are installed at the four corners of the lower part of the base 2. The water collection boxes 3 are connected to the internal reaction chamber of the base 2, and a drain hole 4 is opened on the lower side of the outside of the water collection box 3. Several motors corresponding to the wings are installed on the body of the drone 1. The motors are electrically connected to the hydrogen fuel cell inside the base 2. Since the chemical reaction in the reaction chamber produces water, the water in the reaction chamber will flow into the water collection boxes 3 on the lower side and be discharged through the external drain hole 4. The hydrogen fuel cell also supplies power to the motors of the body to ensure the long-endurance flight mission of the drone. The hydrogen fuel cell has high energy density and is suitable for heavy-load or long-endurance missions. The flight time is far longer than that of traditional battery-powered drones, and it is environmentally friendly and pollution-free.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
