In recent years, by virtue of the characteristics of stable offshore resources, high power generation, convenience in consumption and the like, the offshore wind power generation industry has been rapidly developed, and the offshore wind power generation has a wide market prospect. The offshore wind turbine mainly comprises three parts: fan basis, tower section of thick bamboo, upper portion unit. In order to facilitate the wind turbine landing, a wind turbine foundation is usually provided with a ship-leaning system, a platform and other components in a matching manner. With the development of offshore wind power, the requirements on the basic accessory components of the wind turbine are higher and higher.
The offshore wind turbine foundation platform has less wind acting force and increases the rigidity of the platform, and generally adopts a grid structure; to facilitate grid installation, the grid size is typically combined with the platform beam system. Due to the complexity of offshore operations and construction time conditions, grilles often have no way to guarantee a 25 year life and are therefore typically designed as replaceable structures.
The traditional grid and fan platform beam system is fixed by saddle clamps, grid fixing hooks and other modes. The saddle clamp is generally used for connecting 2 grids, and the grids cannot be connected and fixed with the platform beam; the grid fixing hook is designed and synthesized by a saddle clamp and a beam hook by adopting round steel matched with a beam system, and the beam is fixedly connected with the adjacent grid. In the actual construction process, the problem of adaptation between the grid fixing hook and the beam system is more prominent, and if the fixing hook is completely matched with the beam system, the construction operation is difficult; if the fixed hook is slightly larger than the beam system, the problems of looseness and the like easily occur in the construction process.
