Embodiment Construction

[0022] The present invention will be further explained in detail below in conjunction with the accompanying drawings and specific embodiments, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0023] Such as figure 1 As shown, the piling noise reduction device in the present invention includes a noise reduction mechanism, an underwater air bag 1 arranged on the noise reduction mechanism from top to bottom, and a ballast device 2 arranged at the second end of the noise reduction mechanism. The noise reduction mechanism It is a cone structure with a large opening at one end and a small opening at the other end. It can also be called a trumpet structure. The large mouth end and the small mouth end are connected, and neither the large mouth end nor the small mouth end is closed. The large mouth end of the structure is connected to the ballast device 2, and the underwater airbag 1 is arranged from top to bot...

Abstract

The invention relates to a new type of piling noise reduction device, which includes a noise reduction mechanism, an underwater air bag arranged on the noise reduction mechanism from top to bottom, and a ballast device arranged on the noise reduction mechanism. The noise reduction mechanism is open at one end. A cone structure with a small opening at one end, the underwater air bag provides buoyancy for the cone, the large mouth end of the cone structure is connected to the ballast device, the noise reduction mechanism includes a high-pressure tube spirally coiled, the high-pressure The tube spirally extends from the small mouth end of the noise reduction mechanism to the large mouth end of the noise reduction mechanism. A number of air holes are arranged along the side wall of the high-pressure pipe. The high-pressure pipe is connected to an air compressor. The side wall of the noise reduction mechanism is provided with elastic small ball. The noise reduction device forms a bubble curtain and simultaneously forms a noise reduction mechanism together with the elastic balls to achieve a noise reduction effect.

Description

technical field [0001] The invention relates to an underwater noise reduction device, in particular to a novel underwater piling noise reduction device. Background technique [0002] At present, as clean energy is more and more popularized and utilized, offshore wind turbine piling technology is also receiving more and more attention. Offshore wind turbine piling projects are mainly distributed in offshore coastal areas with abundant wind energy, and operations are carried out in shallow waters with a water depth of 10-30m. [0003] However, the impact piling noise emitted by offshore wind turbine piling not only affects the normal living activities of human beings, but also causes various serious noise pollution to the marine environment and affects the living environment of marine organisms. It is imperative to take noise reduction measures for offshore wind turbine piling. Contents of the invention [0004] In order to effectively reduce noise for underwater operation...
