Problems solved by technology

In the prior art, under the sea surface, the foundation around the foundation is relatively loose under the immersion of seawater, and there is a lack of effective protective measures to prevent the foundation from being washed away. The foundation around the foundation is easily affected by seabed erosion, for example, tidal changes or storms Weather will cause scours. Seabed scours will wash away the foundation around the foundation, causing the height of the foundation around the foundation to decrease, affecting the stability of the foundation, thereby reducing the service life of offshore wind turbines and affecting the safety of offshore wind turbines.

Embodiment 1

[0030] figure 1 A schematic diagram showing the protection device for the tower foundation of the offshore wind power generating set in this embodiment is shown in . The protective device includes a protective tube 1 sleeved on the periphery of the foundation 2, and forms a cavity 3 with the foundation 2 for storing solid materials; the bottom of the protective tube 1 is fixed on the seabed 13, and is provided with an opening 18 to protect The top of the barrel 1 is fixed on the bottom of the workbench 14; the workbench 14 is provided with at least one feeding port 7 for filling solid materials.

[0031] It should be noted that although figure 1 The foundation 2 of the offshore wind power generating set shown in the figure adopts a single-pile foundation, but the protection device in this embodiment is not limited to be applied to a single-pile foundation, and can also be applied to a multi-pile foundation.

[0032] The protective device of this embodiment is provided with a...

Abstract

The invention provides a protection device of an offshore wind turbine generator system tower foundation. The protection device comprises a protection cylinder coating the outer periphery of the foundation; a cavity is formed between the protection cylinder and the foundation for storing a solid material; the bottom of the protection cylinder is fixed on a seabed, and is provided with an opening; the top of the protection cylinder is fixed at the bottom of a worktable; and the worktable is provided with at least one feed port for charging the solid material. The protection device of the offshore wind turbine generator system tower foundation can effectively make up the influence of seabed scouring on the ground around the foundation, forms effective protection for seabed scouring, stably fixes the foundation in the sea, reduces maintenance of the foundation, and effectively prolongs the service life of the foundation.

Description

technical field [0001] The invention relates to the field of offshore wind power generating sets, in particular to a protection device for a tower foundation of an offshore wind generating set. Background technique [0002] Offshore wind turbines are wind turbines erected on the sea for offshore power generation. In the prior art, the tower of the offshore wind power generation unit is usually supported on the sea surface by the foundation. The foundation usually adopts a single pile structure or a multi-pile structure. pylon. In the prior art, under the sea surface, the foundation around the foundation is relatively loose under the immersion of seawater, and there is a lack of effective protective measures to prevent the foundation from being washed away. The foundation around the foundation is easily affected by seabed erosion, for example, tidal changes or storms Weather will cause scours, and seabed scour will wash away the foundation around the foundation, causing the...
