Aquaculture net cage structure based on offshore wind power multi-pile foundation and construction method

Abstract

The invention belongs to the field of offshore wind power engineering, and particularly relates to an aquaculture net cage structure based on an offshore wind power multi-pile foundation and a construction method. The structure comprises the pile foundation and a net cage surrounding the pile foundation, the pile foundation comprises a plurality of annularly arranged pile legs, the net cage comprises a plurality of netting arranged between the adjacent pile legs, the netting and the pile legs are arranged in a matched mode through a sleeve assembly, the sleeve assembly comprises a plurality ofring beams arranged outside the pile legs in a sleeving mode, the plurality of ring beams are fixedly connected together through at least one stand column, a fixing rod is fixedly matched with the stand column, an anchor chain ring of the netting and the stand column are arranged in a matched mode, and the edge of the netting is connected with the fixing rod in a matched mode. The structure has the beneficial effects that a fixing method of the sleeve assembly is adopted, and the underwater construction is not needed, so that the construction difficulty is reduced; the net cage is fixed through a draught fan foundation, so that the cost of a net cage anchoring system is reduced; and a draught fan utilizes resources above the sea level, and the net cage utilizes resources below the sea level, so that the three-dimensional development of ocean resources is achieved.

Description

technical field [0001] The invention belongs to the field of offshore wind power engineering, and in particular relates to a culture cage structure and construction method based on a multi-pile foundation of offshore wind power. Background technique [0002] As a renewable energy source, offshore wind power has developed rapidly in recent years. Among them, high pile caps are used in many places in our country. The foundation structure of the high pile cap includes a concrete cap above sea level and a group of steel pipe piles at the bottom of the cap. It is connected with the wind power tower through the flange, so that the wind turbine and the foundation are integrated. [0003] For my country's marine fishery cage culture, it began in the late 1970s and developed rapidly in the 1990s, and the number of cultured species is also increasing day by day. However, due to the harsh marine environment and frequent extreme weather, this is a great challenge to the material, str...

Problems solved by technology

The existing breeding cages based on multi-pile foundations for offshore wind power are usually installed on the foundation of the caps and pile foundations when the caps have been built, but for offshore wind power multi-pile foundations and breeding cages Whether there is a better and faster way to build aquaculture cages, especially when the foundation piles have been built but the caps have not been built, the existing technology has not given a corresponding plan in this regard
