Abstract

The invention discloses a device for abating offshore draught fan foundation piling noise. The device comprises a steel cofferdam, wherein the outer wall of the steel cofferdam is provided with a noise reduction wall, the inner wall of the steel cofferdam is provided with a rectangular tube with air pores, in the piling process, the compressed air is discharged through the air pores, multiple layers of air bubble curtains are formed between a steel tube pile and the steel cofferdam, and the noise in the piling process can be reduced by adopting the double means of the multiple layers of air bubble curtains and the noise reduction wall. The device is simple in structure, easy to realize and low in cost, the noise pollution in the offshore piling construction process can be effectively reduced, the ocean ecological system can be protected, and the balance of the novel energy development and the ecological environment can be maintained.

Description

technical field

[0001] The invention relates to a noise reduction device, in particular to a noise reduction device for reducing noise during the piling process of an offshore fan foundation. Background technique

[0002] At present, the foundations of offshore wind turbines at home and abroad mostly adopt foundation forms such as single piles, tripods, and jackets, and most of these foundation forms require underwater piling construction. The high-decibel noise generated by underwater piling construction is harmful to those living around the sea How to effectively control the noise impact caused by piling construction during the construction of offshore wind farms and maintain the balance between new energy development and the ecological environment has become an industry urgent problem to be solved. Contents of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a noise reduction device for offshore wind turbine ...
