Description

Technical Field

[0001] This utility model relates to the field of wind turbine nacelle cleaning technology, and in particular to a foam spraying structure for a wind turbine nacelle cleaning robot. Background Technology

[0002] Wind power is a key clean energy source being developed globally. As an important component of wind turbine generators, the outer wall of the wind turbine nacelle may accumulate debris during long-term operation and requires cleaning. Existing cleaning drone robots have been found to fail to spray foam onto the wind turbine nacelle due to high-altitude operation and the influence of airflow from the drone. Therefore, a foam spraying structure for a wind turbine nacelle cleaning robot is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a foam spraying structure for a wind turbine nacelle cleaning robot, comprising a suspended frame with steel cables at both ends of the top of the suspended frame. The top ends of the steel cables are fixed to a drone. A magnetic spraying assembly is fixedly connected to the bottom of the suspended frame for magnetically covering the surface of the wind turbine nacelle. A spraying pipe is provided inside the suspended frame, and several branch pipes are provided at the bottom of the spraying pipe. The branch pipes are evenly distributed on the magnetic spraying assembly. The top end of the spraying pipe is connected to a foam storage mechanism at the bottom of the drone.

[0004] Furthermore, the magnetic spraying assembly includes an unfolding plate that is fixedly connected to the suspension frame as an integral part, with a number of spraying holes evenly opened on the unfolding plate, and branch pipes placed inside the spraying holes.

[0005] Furthermore, several electromagnetic components are arranged in an array below the unfolding plate, and movable components are movably connected between adjacent electromagnetic components. Several lifting rings are fixedly connected to the lower surface of the unfolding plate. The electromagnetic components at the top are movably connected to the lifting rings of the unfolding plate through movable components. A tarpaulin is fixedly connected to and covered the outside of the electromagnetic components.

[0006] Furthermore, a buffer pad is fixedly connected to the end of the electromagnetic component used for magnetic attraction.

[0007] Furthermore, the electromagnetic component includes a housing, on the outer wall of which four hanging rings are arranged in a circumferential array, and the hanging rings of adjacent electromagnetic components are connected by movable parts.

[0008] Furthermore, an iron core is fixedly connected inside the outer casing, and a coil is wound around the outer periphery of the middle part of the iron core.

[0009] Furthermore, the movable component includes two parallel plates arranged in parallel, with a pivot between each end of the two parallel plates, and the pivot is movably connected to the lifting ring and the hanging ring. Beneficial effects

[0010] When cleaning a wind turbine nacelle by spraying foam, the drone approaches the nacelle, bringing the magnetic spraying assembly close to it. The assembly is then energized, generating electromagnetic force. Under this magnetic force, the assembly magnetically adheres to the surface of the nacelle. The foam storage mechanism at the bottom of the drone then sprays foam through the spray nozzle, allowing it to enter the gap between the magnetic spraying assembly and the nacelle. This process effectively avoids the influence of airflow, preventing the foam from being sprayed onto the nacelle.

[0011] Electromagnetic components are used to generate magnetic force when energized, which magnetically attracts and covers the wind turbine nacelle. The tarpaulin prevents foam from flying out. The movable components are used to connect several electromagnetic components, reducing the influence between adjacent components and ensuring that all electromagnetic components can be magnetically covered on the wind turbine nacelle. It can adapt to the curved surface of the wind turbine nacelle. When spraying foam, the foam is sprayed into the gaps between adjacent electromagnetic components through branch pipes. After spraying, the gaps are filled with foam, and the foam spraying of the wind turbine nacelle is completed.

[0012] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0020] Combined with appendix Figures 1 to 6 A foam spraying structure for a wind turbine nacelle cleaning robot includes a suspended frame 1. Steel cables 3 are provided at both ends of the top of the suspended frame 1, with the top ends of the steel cables 3 fixed to a drone. A magnetic spraying assembly 4 is fixedly connected to the bottom of the suspended frame 1 for magnetically covering the surface of the wind turbine nacelle. A spraying pipe 2 is provided inside the suspended frame 1, with several branch pipes at the bottom end of the spraying pipe 2. The branch pipes are evenly distributed on the magnetic spraying assembly 4. The top end of the spraying pipe 2 is connected to a foam storage mechanism at the bottom of the drone.

[0021] In practical implementation, when foam needs to be sprayed for cleaning the wind turbine nacelle, the drone approaches the wind turbine nacelle, bringing the magnetic spraying component 4 close to the nacelle. The magnetic spraying component 4 is then energized, generating electromagnetic force. Under the influence of this magnetic force, the magnetic spraying component 4 magnetically covers the surface of the wind turbine nacelle. Then, the foam storage mechanism at the bottom of the drone sprays foam through the spraying pipe 2, allowing the foam to enter the gap between the magnetic spraying component 4 and the wind turbine nacelle, thus completing the spraying of foam onto the wind turbine nacelle. This effectively avoids the influence of airflow and prevents the foam from being sprayed onto the wind turbine nacelle due to airflow.

[0022] Furthermore, the magnetic spraying assembly 4 includes an unfolding plate 41 that is fixedly connected to the suspension frame 1 as an integral part, and a plurality of spraying holes 42 are evenly opened on the unfolding plate 41, with the branch pipe located inside the spraying holes 42.

[0023] In practical implementation, the unfolded version 41 and the suspended frame 1 are used to unfold the whole structure, and the branch pipes are used to spray foam.

[0024] Furthermore, several electromagnetic components 43 are arranged in an array below the unfolding plate 41, and movable components 44 are movably connected between adjacent electromagnetic components 43. Several lifting rings 46 are fixedly connected to the lower surface of the unfolding plate 41. The electromagnetic components 43 located at the top are movably connected to the lifting rings 46 of the unfolding plate 41 through the movable components 44. A tarpaulin 47 is fixedly connected to and covered the outside of the several electromagnetic components 43.

[0025] In practical implementation, the electromagnetic component 43 is used to generate magnetic force when energized, and covers the wind turbine nacelle cover by magnetic attraction. The tarpaulin 47 is used to prevent foam from flying out. The movable component 44 is used to connect several electromagnetic components 43 to reduce the influence between adjacent electromagnetic components 43, so that all electromagnetic components 43 can be magnetically covered on the wind turbine nacelle cover. It can adapt to the curved surface of the wind turbine nacelle cover. When spraying foam, the foam is sprayed into the gaps between adjacent electromagnetic components 43 through the branch pipe. After the spraying is completed, the gap is filled with foam, and at this time the foam spraying of the wind turbine nacelle cover is just completed.

[0026] Furthermore, a buffer pad 45 is fixedly connected to one end of the electromagnetic component 43 for magnetic attraction.

[0027] In practical implementation, the setting of buffer pads 45 reduces the impact force generated by the electromagnetic component 43 when it is magnetically attracted, thereby reducing damage to the wind turbine nacelle.

[0028] Furthermore, the electromagnetic component 43 includes a housing 431, on the outer wall of which four hanging rings 432 are arranged in a circumferential array, and the hanging rings 432 of adjacent electromagnetic components 43 are connected by a movable component 44.

[0029] In practice, adjacent electromagnetic components 43 are connected through hanging ring 432 and movable component 44.

[0030] Furthermore, an iron core 443 is fixedly connected inside the outer casing 431, and a coil 434 is wound around the middle periphery of the iron core 443.

[0031] In practice, when magnetic force is generated, coil 434 is energized, causing the iron core 443 and coil 434 to generate magnetic force as a whole.

[0032] Furthermore, the movable component 44 includes two parallel plates 441 arranged in parallel, with a pivot 442 between each end of the two parallel plates 441. The pivot 442 is movably connected to the lifting ring 46 and the hanging ring 432.

[0033] In practical implementation, the curved surface of the wind turbine nacelle can be effectively adapted by setting the movable part 44.
