Title:
SELF-MAINTAINING ANTI-SCOURING DEVICE FOR OFFSHORE WIND FARM PILE FOUNDATION
Document Type and Number:
WIPO Patent Application WO/2023/151318
Kind Code:
A1
Abstract:
The present invention discloses a self-maintaining anti-scouring device for an offshore wind farm pile foundation, which relates to the technical field of pile foundation anti-scouring. The self-maintaining anti-scouring device comprises a fixing portion which is fixedly arranged on the seabed; a mounting portion which is arranged above the fixing portion and is used for mounting wind power equipment; and a sand screening portion which comprises a sand screening ring and an impeller arranged below the mounting portion. The sand screening ring is sequentially provided with a water inlet, a stirring cavity and a sand outlet from top to bottom. A drainage hole in communication with the stirring cavity is formed in the side face of the sand screening ring. The impeller is rotatably arranged in the stirring cavity. In the present invention, the impeller rotates horizontally in the sand screening ring such that silt and seawater are separated under the action of centrifugal force and are respectively discharged from the sand outlet and the drainage hole. At the same time, seawater enters the stirring cavity from the water inlet, and the separated silt falls to the periphery of the fixing portion, so as to prevent the foundation layer on the periphery of the fixing portion from falling off and being pitted due to wave scouring, thereby achieving anti-scouring purposes.
