Abstract
The utility model discloses a denoising device for offshore wind turbine foundation piling. The denoising device for offshore wind turbine foundation piling comprises a steel cofferdam. A silencing wall is arranged on the outer wall of the steel cofferdam. Rectangular tubes provided with air holes are arranged on the inner wall of the steel cofferdam. In the process of piling, compressed air is discharged from the air holes, and a multi-layer bubble curtain is formed between a steel pipe pile and the steel cofferdam. The double means including the multi-layer bubble curtain and the silencing wall are taken to achieve denoising in the process of piling. According to the denoising device for offshore wind turbine foundation piling, the structure is simple, implementation is easy, manufacturing cost is low, noise pollution caused in the construction process of offshore piling can be effectively reduced, protection of the marine ecosystem is facilitated, and balance between new energy development and ecological environment is kept.
Description
Technical field
The utility model relates to a kind of noise reduction apparatus, the noise reduction apparatus of particularly in a kind of offshore wind turbine foundation piling process, noise being subdued.
Background technology
At present, offshore wind turbine foundation adopts the base forms such as single pile, tripod, jacket more both at home and abroad, and these base form major parts need to be carried out underwater pile driving construction, the construct high-decibel noise that produces of underwater pile driving produces and has a strong impact on living in this marine site biology around, grievous injury and interference marine organisms, destroy marine ecosystems balance, how effectively controlling the caused noise of piling construction in marine wind electric field process of construction impacts, keep the balance between new energy development and ecological environment, become industry and need badly the problem of solution.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can effectively reduce the noise vibration producing in the fluid of underwater pile driving when construction coastal waters, and cost of production is low, easily manufacture, firm and durable for offshore wind turbine foundation piling noise reduction apparatus.
The utility model solves the technical scheme that its technical problem adopts:
A kind of offshore wind turbine foundation piling noise reduction apparatus that is used for, comprises steel cofferdam, and described steel cofferdam outer wall is provided with noise reduction wall.
The inwall of described steel cofferdam is provided with some rectangular tubes that are circumferentially arranged, and described rectangular tube is provided with pore, and described rectangular tube connects air compressor machine by appendix.
Described noise reduction wall is by assembled formation of some monolithic silencing blocks.
Described monolithic silencing block is provided with inside and empties structure.
The beneficial effects of the utility model are: steel cofferdam outer wall of the present utility model is provided with noise reduction wall, the inwall of steel cofferdam is provided with the rectangular tube with pore, in piling process, compressed air is discharged by pore, between steel pipe pile and steel cofferdam, form MLV curtain, adopting MLV curtain and noise reduction wall two methods to realize subdues the noise in piling process, simple in structure, easily realize, cheap, can effectively reduce the noise pollution in marine guidance piling work progress, contribute to protect marine ecosystems, keep the balance between new energy development and ecological environment.
