摘要： The present invention relates to a rotating construction platform based on a single pile foundation, comprising a rotary connecting mechanism which is disposed on the top part of a single pile foundation and a working platform which is disposed on the rotary connecting mechanism. The rotary connecting mechanism comprises an upper connecting cylinder, a lower connecting cylinder, and a rotary support structure located between the upper connecting cylinder and the lower connecting cylinder. The working platform is fixedly connected to the upper connecting cylinder, the lower connecting cylinder is removably fixed to the top part of the single pile foundation, and at least one side of the working platform extends out of a side edge of the single pile foundation. The rotating construction platform of the present invention is stable and reliable, and can replace original methods which require the use of offshore construction work vessels or temporary construction platforms, improving the continuity of construction work, saving construction time and costs, preventing ship machines from being rocked by waves and hitting a single pile foundation when the construction space is small, improving the construction positioning accuracy, and ensuring construction quality.

摘要： 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.
