Embodiment Construction

[0022] The present invention will be further explained in detail below with reference to the 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 7 noise reduction device of the present invention includes a noise reduction mechanism, an underwater airbag 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 mechanism is a vertebral structure with one end opening and the other opening small. It can also be called a horn structure. The large mouth end of the body structure is connected to the ballast device 2, and the underwater airbag 1 is arranged from top to bottom, which can make the buoyancy provided during the sinking process become greater and greater, which can ensure that the gravity of the ballast device is greater than the ove...

Abstract

The invention relates to a novel pile driving noise reduction device. The novel pile driving noise reduction device comprises a noise reduction mechanism, an underwater air bag which is arranged on the speed reduction mechanism and from top to bottom and a ballast device arranged on the second end of the noise reduction mechanism. The speed reduction mechanism is of a cone structure with a large opening in one end and a small opening in the other end, the underwater air bag provides buoyancy for the cone structure, the large opening end of the cone structure is connected with the ballast device, the speed reduction mechanism comprises a high-pressure pipe which is spirally circled, a high-pressure rubber pipe circles from the small end of the noise reduction mechanism and extends to the large opening end of the noise reduction mechanism, multiple air holes are formed along the side wall of the high-pressure pipe, the high-pressure pipe is connected with an air compressor, and elastic small balls are arranged on the side wall of the noise reduction mechanism. The noise reduction device forms a bubble curtain, meanwhile, the curtain and the elastic small balls jointly form the noisereduction mechanism, and the noise reduction effect is achieved,

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 used, 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 are operated in shallow waters with a depth of 10-30m. [0003] However, the impact piling noise generated by offshore wind turbine piling not only affects the normal living activities of human beings, but also causes serious noise pollution to the marine environment and affects the living environment of marine organisms. Noise reduction measures for offshore wind turbine piling are imperative. Summary of the invention [0004] In order to effectively reduce noise and noise in subsea operations, the present invention provides a piling noi...
