Description

Technical Field

[0001] This utility model relates to the field of defrosting equipment technology, and in particular to defrosting drone components. Background Technology

[0002] As offshore wind farms continue to expand and the number of wind turbines increases, the drawbacks of traditional defrosting technologies in terms of labor costs, workflow complexity, and cost control are becoming increasingly prominent. Currently, most defrosting is done manually or by drones. Manual defrosting is highly dangerous, inefficient, and inflexible in terms of location. While drone defrosting can improve efficiency, it lacks adaptability and inevitably has blind spots. Given these industry challenges, there is an urgent need for an innovative defrosting technology to overcome these limitations.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, we have specially provided defrosting drone components to solve the technical problems of low defrosting efficiency, poor defrosting adaptability, and defrosting blind spots. Utility Model Content

[0004] The purpose of this invention is to provide a defrosting drone component to solve the technical problems of low defrosting efficiency, poor defrosting adaptability, and defrosting blind spots.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A defrosting drone assembly, comprising a defrosting drone and a defrosting robot, wherein the defrosting robot is suspended from the bottom of the defrosting drone using an automatic release hook;

[0007] The defrosting drone includes a drone body, which is equipped with a drone arm, a drone high-pressure nozzle, and a drone camera. The drone body also includes a battery, a controller, a de-icing agent tank, and two solenoid valve assemblies. The drone high-pressure nozzle is connected to the de-icing agent tank.

[0008] The defrosting robot includes a robot body, on which a high-pressure nozzle and a camera are mounted. The robot body is connected to multiple mechanical legs, and the ends of the mechanical legs are equipped with vacuum suction cups.

[0009] In a preferred embodiment, the drone arm is provided with multiple arms, each arranged symmetrically, and the end of each drone arm is provided with a motor blade assembly.

[0010] In a preferred embodiment, the bottom of the drone is provided with two symmetrical bottom supports, and a connecting rod is provided between the bottom supports. The top of the automatic release hook is connected to the connecting rod.

[0011] The top of the robot body is equipped with a hook, and the bottom of the automatic unlocking hook is connected to the hook.

[0012] In a preferred embodiment, the automatic release hook includes a lifting ring, a steel wire rope, and an automatic release device. The top and bottom of the steel wire rope are respectively connected to the lifting ring and the automatic release device, and the lifting ring is connected to a connecting rod.

[0013] The hook consists of a lifting ring, a steel wire rope, and an automatic release device (available for direct purchase). The automatic release device can automatically release the hook based on gravity. When the drone descends and the materials land, the vertical tension decreases sharply. The hook is subjected to gravity and rotates to the right, creating an offset angle that causes the defrosting robot to automatically release the hook.

[0014] The typical application of defrosting drones is for offshore wind turbine defrosting, and this equipment is mounted on a ship. The drone is remotely controlled and takes off. The drone is positioned at an appropriate distance from the center of the wind turbine's rotation, and a camera captures images. Visual analysis can detect if frost is affecting the blade's speed. The drone then defrosts the blades. The defrosting principle is as follows: the drone connects to the ship's air compressor, which in turn connects to a solenoid valve assembly. Two solenoid valves control high-pressure spray guns, which spray de-icing agent to defrost the blades.

[0015] The compressor is on the ship and connected to the drone's solenoid valve via a long air pipe, without affecting the drone's flight. The solenoid valve is connected to a water tank for the de-icing agent, which in turn is connected to a high-pressure spray gun. The drone then sprays the de-icing agent. However, the drone has blind spots, namely the gaps between the impeller and blades, which it cannot access, requiring a defrosting robot for defrosting.

[0016] The defrosting robot consists of a welded frame, joint motors, a controller, a solenoid valve plate assembly, a PLC, a wireless IP, a battery, and a vacuum generator. The mechanical legs include several arm segments connected by joint motors.

[0017] The defrosting robot is hoisted onto the wind turbine rotor by a drone and automatically detaches. The robot's two solenoid valves connect to the de-icing agent tank and air compressor on the ship, and are connected to high-pressure nozzles. Six solenoid valves connect the air compressor and vacuum generator. The vacuum generator creates a vacuum in the vacuum suction cups, allowing the defrosting robot's legs to adhere to the blade surface, overcoming gravity to adhere to the blade surface, much like a gecko climbing a wall. It can crawl at any position on the blade to spray de-icing agent.

[0018] The beneficial effects of this utility model are:

[0019] This solution employs a combination of drone defrosting and vacuum adsorption robot defrosting. The advantages of this approach are that drone defrosting significantly improves defrosting efficiency, while robot defrosting can adapt to terrain and defrost areas that drone defrosting cannot reach. Therefore, this solution not only offers high efficiency but also good adaptability, reduces defrosting blind spots, and solves the technical problems of low defrosting efficiency, poor adaptability, and blind spots in current defrosting methods. It also reduces manual operation and ensures high safety.

[0020] After extensive defrosting by drones, a defrosting robot is deployed. Equipped with high-pressure nozzles and cameras, the robot can target specific frosted areas on the blades or areas blinded by the drone's defrosting. Using images fed back from the camera, operators can precisely control the robot, ensuring the aerodynamic performance of critical blade components. This precise defrosting method avoids unnecessary defrosting of the entire blade, reducing maintenance costs.

[0021] The defrosting robot, equipped with multi-segment mechanical legs and a vacuum suction cup, can firmly attach to the blades for defrosting. Compared to traditional simple defrosting equipment, it offers higher defrosting efficiency and more effectively removes stubborn frost layers. This efficient defrosting operation reduces downtime caused by frost buildup in wind turbines, improves power generation efficiency, and brings economic benefits. The defrosting robot operates stably on the blades, causing minimal damage and reducing additional maintenance costs. Furthermore, this defrosting robot requires only a small number of operators for remote control, and its stable and reliable operation reduces the frequency of manual inspections and maintenance, lowering labor costs.

[0039] The hook 19 consists of a lifting ring 15, a steel wire rope 16, and an automatic unhooking device 17 (available for direct purchase). The automatic unhooking device 17 can automatically unhook according to gravity. When the drone descends and the materials land, the vertical tension decreases sharply. The hook is subjected to gravity and rotates to the right to generate an offset angle, which causes the defrosting robot 3 to automatically unhook.
