Description

Technical Field

[0001] This utility model relates to the field of fan blade shell technology, and in particular to a fan blade shell for wind power generation. Background Technology

[0002] The outer casing of a wind turbine blade is a protective structure covering the outside of the wind turbine blades. It is generally made of composite materials, such as glass fiber and carbon fiber reinforced resin-based composites. The blade casing plays a crucial role. Firstly, it protects the internal structural materials and components of the blade from erosion and damage caused by natural factors such as wind, rain, ultraviolet radiation, and sandstorms, extending the blade's lifespan. Secondly, it improves the aerodynamic performance of the blade. By optimizing the shape and surface finish of the casing, it reduces airflow resistance, increases wind energy conversion efficiency, and allows the blade to rotate more efficiently in the wind, thereby enhancing the overall efficiency of wind power generation. Currently, blade casings simply wrap the blades; during use, a large amount of dust and other impurities remain on the surface, causing erosion and damage, leading to a reduced lifespan.

[0047] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a wind turbine blade housing.

[0048] A wind turbine blade housing includes a mounting component 1 and multiple blades 2. The housing also includes a fixing mechanism mounted on the mounting component 1 for mounting the blades 2, and a cleaning mechanism mounted on the blades 2 for cleaning them. The cleaning mechanism includes: a housing 3 mounted on and fixedly connected to the blades 2; multiple fixing grooves 4 mounted on and fixedly connected to the housing 3; multiple guide rails 5 positioned within and fixedly connected to the fixing grooves 4; multiple sliding members 6 mounted on and slidably connected to the guide rails 5; a moving device mounted on the sliding members 6 for moving the components; and multiple scrapers 7 mounted on the moving device for cleaning the housing 3.

[0049] refer to Figure 1 and Figure 4 In a preferred embodiment, the moving device includes: a mounting part disposed on the sliding member 6 for mounting the component; and a moving part disposed on the mounting part for moving the component.

[0050] refer to Figure 5 In a preferred embodiment, the mounting part includes: a mounting bracket 8, which is disposed on the sliding member 6 and fixedly connected to the sliding member 6; and a plurality of mounting slots 9, which are disposed on the mounting bracket 8 and fixedly connected to the mounting bracket 8.

[0051] refer to Figure 5 In a preferred embodiment, the moving part includes: a plurality of cylinders 10, wherein the plurality of cylinders 10 are disposed in the mounting groove 9 and fixedly connected to the mounting groove 9; and a plurality of mounting plates 11, wherein the plurality of mounting plates 11 are disposed on the cylinders 10 and fixedly connected to the cylinders 10.

[0052] In this configuration, a sensor is installed on the top of the outer casing 3, which activates the cylinder 10 when the slider 6 slides to the top, thereby causing the scraper 7 to leave the surface of the outer casing 3 and preventing impurities from being carried to the bottom when the slider 6 drives the scraper 7 back to the bottom; the cylinder 10 is used to adjust the position of the scraper 7; a drive component and a sensor component are installed inside the slider 6, which can identify when the slider 6 can move with gravity and provide power through the drive component to perform the scraping work.

[0053] refer to Figure 2 In a preferred embodiment, the fixing mechanism includes: a connecting part disposed on the mounting member 1 and the fan blade 2 for connecting the components; and a fixing part disposed on the connecting part for fixing the components.

[0054] refer to Figure 2 In a preferred embodiment, the connecting part includes: a plurality of connecting grooves 12, which are disposed on the mounting member 1 for fixing the component; and a connecting member 13 disposed on the fan blade 2 and fixedly connected to the fan blade 2.

[0055] refer to Figure 3 In a preferred embodiment, the fixing part includes: a fixing post disposed on the connector 13 and fixedly connected to the connector 13; and a fixing head, having multiple fixing heads disposed on the connector 13 and fixedly connected to the connector 13.

[0056] This device, by incorporating a cleaning mechanism, effectively protects the fan blades 2 inside the device through the outer casing 3, preventing them from being eroded and damaged by natural factors such as wind, rain, ultraviolet rays, and sandstorms, thus extending the service life of the fan blades 2. The cleaning mechanism also effectively cleans the surface of the outer casing 3, protecting it from corrosion and damage, and further extending its service life.

[0057] Working Principle: In use, the outer casing 3 is fixed to the connector 13 to protect the fan blade 2. Then, the fixing post and fixing head are inserted into the connecting groove 12 to initially fix the fan blade 2. Finally, the fan blade 2 is fixed to the mounting part 1 with bolts, completing the installation of the fan blade 2. When the fan blade 2 is in operation, as it rotates, the sliding part 6 moves along the guide rail 5 under the action of gravity, simultaneously driving the mounting frame 8 to move. This allows the scraper 7 to move along the surface of the outer casing 3, scraping and cleaning the surface of the outer casing 3. The surface dust and other impurities are cleaned to prevent damage and corrosion to the outer casing 3, thus effectively protecting the outer casing 3. When the sliding member 6 slides to the side away from the mounting member 1, the sensor detects the position of the sliding member 6 and starts the cylinder 10. The cylinder 10 drives the mounting plate 11 and the scraper 7 to retract, allowing the scraper 7 to leave the surface of the outer casing 3. Then the fan blade 2 continues to rotate, allowing the sliding member 6 to return to the side close to the mounting member 1 along the guide rail 5. At the same time, the cylinder 10 extends again to allow the scraper 7 to contact the surface of the outer casing 3, waiting for the next scraping operation.

[0058] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
