Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power piles, in particular to an offshore wind power protection device. Background Art

[0002] Offshore wind turbine piles are an important part of offshore wind turbines and are used to support and fix wind turbines. The following are some detailed introductions to offshore wind turbine piles: Type: Single pile foundation: Currently, it is the most widely used foundation type in offshore wind power projects. It is mainly composed of steel pipe piles and is fixed by inserting pile legs below the seabed. The single pile foundation has a simple structure, fast construction, and relatively low cost, but the structural stiffness is small, the natural frequency is low, it is greatly affected by seabed scouring, and has high requirements for construction equipment. Gravity foundation: It was born earlier and is generally applicable to water depths of no more than 40 meters. It relies on the deadweight of the foundation to resist the load of wind turbines and various environmental loads. It generally adopts a prefabricated reinforced concrete caisson structure, which is filled with sand, gravel, slag or concrete ballast materials. The gravity foundation has good stability, but has high requirements for the foundation (preferably a hard seabed with a shallow cover layer). Multi-pile foundation: It was first invented in China. Before it was applied to the foundation of wind turbines, it was a common structure for coastal docks and bridge piers. It was developed from the foundation structure of port engineering. Multi-pile foundations are stable enough in soft seabed conditions and can play a unique role in wind farms near shipping routes. Jacket foundation: usually has 3-4 pile legs, which are connected to each other by struts to form a spatial truss structure with sufficient strength and stability. Jacket foundation is suitable for waters with a depth of 20-50 meters and is one of the most commonly used types.

[0003] According to the patent number published on the China Patent Network: CN220107542U, the utility model discloses an offshore wind power cable ecological protection device, including a J-shaped conduit, a front sacrificial pile and a plurality of mud-entry end protectors connected to the submarine cable in sequence, one end of the submarine cable is connected to the offshore wind power pile through the J-shaped conduit; the front sacrificial pile is inserted and fixedly connected to the bottom of the seabed, and the submarine cable passes through the front sacrificial pile; the other end of the submarine cable passes through a plurality of mud-entry end protectors in sequence and extends to the bottom of the seabed; the outer side of the submarine cable is provided with a plurality of end-to-end connected bending limiters from the outlet of the J-shaped conduit to the end of the mud-entry end protector. The front sacrificial pile structure in the device can produce a shielding effect on the upstream water flow, and can also backfill the mud near the front sacrificial pile to the offshore wind power pile through the wave current for local scouring protection, while reducing the swing amplitude of the submarine cable; the mud-entry end protector can effectively reduce the friction between the bending limiter and the submarine cable and the bed surface, and reduce the cable breaking accident.
