Abstract

The invention discloses an air curtain noise reduction device for an offshore wind power farm. The air curtain noise reduction device comprises a bubble curtain arranged in the mode of surrounding theinner side of a steel pipe pile, and an aquiculture area is located in the bubble curtain; the bubble curtain is connected with the steel pipe pile; and the bubble curtain comprises an inner-layer waterproof layer and an outer-layer waterproof layer, a hollow structure is formed between the inner-layer waterproof layer and the outer-layer waterproof layer, a bubble generating device is arranged between the inner-layer waterproof layer and the outer-layer waterproof layer, and the bubble generating device is located on the lower part of the bubble curtain. According to the air curtain noise reduction device provided by the invention, shock absorption and noise reduction can be achieved, and oxygen can be continuously supplied to the aquiculture area to improve the living condition of fishschools.

Description

technical field [0001] The invention belongs to the technical field of offshore wind farms, and in particular relates to an air curtain noise reduction device for offshore wind farms. Background technique [0002] China's current offshore wind power technology is developing rapidly. In order to make full use of marine resources, current offshore wind power is usually combined with offshore pasture farming. For example, the Chinese patent document with the publication number CN106172122A discloses a method for marine farming based on offshore wind farms, including the following steps : a. Insert a single-pile wind power foundation to form an enclosed wind farm area, and fix breeding facilities between the wind power foundations; b. Set up an equipment platform at the center of the wind farm area, and the equipment platform and each wind power foundation There are reinforcing rods connected between them, and the algae culture device is fixed below the reinforcing rods to form ...
