Technical Field
[0001] This utility model relates to the field of wind power generation technology, specifically a crystal penetration embedded toughening and waterproofing system at the junction of wind turbine tower and foundation. Background Technology
[0002] In the field of wind power generation, since wind towers are exposed to the natural environment for a long time, the tower and wind turbine foundation are easily eroded by natural factors such as rainwater and sandstorms, resulting in structural damage and affecting the normal operation and lifespan of the wind turbine. Protection is required. However, existing waterproof structures are not only simple and unstable, but also have poor waterproof performance and are easily penetrated by water, which leads to structural damage between the wind turbine foundation and the tower and affects the service life of the wind turbine. In view of this, a crystal penetration embedded toughening waterproof system is proposed at the junction of the wind turbine tower and the foundation. Utility Model Content

[0012] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0015] See Figure 1-2A crystal-penetrating embedded toughening waterproof system for the junction of a wind turbine tower and its foundation includes a wind turbine foundation 2 and a tower 1. A waterproof layer 7 is provided on the surface of the tower 1 and the wind turbine foundation 2. The waterproof layer 7 is made of polymethyl methacrylate coating. Two protective plates 3 are provided on the waterproof layer 7. A triangular strip 4 is provided between the two protective plates 3 and in contact with the tower 1 and the wind turbine foundation 2. A rigid edge 5 is provided on the triangular strip 4. A rubber barrier 6 is provided on the rigid edge 5. The rubber barrier 6 is seamlessly connected to the two protective plates 3.
[0016] This structure, through the waterproof layer 7 formed by the polymethyl methacrylate coating applied to the surfaces of the tower 1 and the wind turbine foundation 2, and the rubber enclosure 6, possesses excellent water resistance and weather resistance. Combined with two protective plates 3, triangular strips 4, and rigid edge 5, it forms a complete and stable waterproof barrier, like putting a protective armor on the tower 1. It achieves seamless sealing, super strong adhesion, and excellent weather resistance, effectively preventing water penetration, protecting the wind turbine foundation 2 and the tower 1 from the erosion of the humid environment, and extending the service life of the wind turbine.
[0017] In some embodiments, the rubber enclosure 6 is a solid structure, and a connecting ring 51 is provided on the rigid side 5. The connecting ring 51 is connected to the rubber enclosure 6, and the cross-section of the connecting ring 51 is T-shaped. The T-shaped connecting ring 51 can not only be stably connected to the rubber enclosure 6, but also better disperse stress when the rubber enclosure 6 is subjected to external force, preventing breakage or deformation.
[0018] In some embodiments, the rubber enclosure 6 is smooth on the side near the tower 1 and protrudes on the side near the wind turbine foundation 2. The rubber enclosure 6 on the side near the tower 1 not only fits better against the surface of the tower 1, reducing gaps, but also prevents water from accumulating on the rubber enclosure 6, helping to guide water flow away quickly. The protrusion on the side near the wind turbine foundation 2 allows for connection with the wind turbine foundation 2, increasing the contact area, improving waterproofing, and to some extent enhancing the support strength and stability of the rubber enclosure 6. In some embodiments, the protective plate 3 is provided with a flat steel channel. This enhances the overall strength of the protective plate 3, giving it better resistance to deformation when facing external impacts or pressures. At the same time, the flat steel channel can serve as a reserved position for installing other components or connecting structures, facilitating subsequent functional expansion or the installation of other waterproof structures according to actual needs.
[0019] In some embodiments, the triangular strip 4 is made of rubber, and anti-slip textures are provided on the side of the triangular strip 4 near the tower 1 and the wind turbine foundation 2. The rubber triangular strip 4 can fit tightly against the surface of the tower 1 and the wind turbine foundation 2, effectively preventing water penetration. The anti-slip textures can increase the friction between the triangular strip 4 and the tower 1 and the wind turbine foundation 2, preventing the triangular strip 4 from sliding or shifting due to external forces or environmental factors during long-term use, thereby ensuring the stability and reliability of the entire waterproof structure and further improving the waterproof effect.
[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
