Description
Technical Field
[0001] The present invention relates to the technical field of wind turbine tower protection devices, and in particular to an anti-corrosion protection device for the exterior of an offshore wind turbine tower. Background Art
[0002] Offshore wind towers are structures used to support offshore wind turbines, usually made of steel or concrete, and designed to withstand strong winds and waves in the marine environment. Offshore wind power has higher power generation efficiency and lower land use conflicts. Offshore wind farms refer to offshore wind power with a water depth of about 10 meters. Compared with onshore wind farms, the advantages of offshore wind farms are mainly that they do not occupy land resources, do not occupy land resources, and reduce conflicts with other land uses.
[0003] However, offshore wind power also faces some challenges, such as high construction and maintenance costs, complex construction environment and potential impact on marine ecology. In particular, the exterior of the wind turbine tower is immersed in seawater for a long time, which can easily cause corrosion to the exterior of the tower and there will be more attachments, which will affect the service life. Usually a layer of protective plate is installed on the outside of the tower, but some existing protective groups on the outside of offshore wind turbine towers are not convenient to disassemble after long-term use. Usually, the entire protective device needs to be dismantled for maintenance, which makes it difficult to replace it later. Moreover, the positions on the surface of the protective device that need maintenance may be different, but the entire device can only be replaced at the same time, which increases the difficulty of maintenance. Therefore, the above problems need to be solved. Summary of the invention

[0022] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
