Description
Technical field
The present invention relates to a kind of noise reduction apparatus, the noise reduction apparatus particularly in a kind of offshore wind turbine foundation piling process, noise cut down.
Background technology
At present, the base forms such as domestic and international offshore wind turbine foundation many employings single pile, tripod, jacket, and these base form major parts need to carry out underwater pile driving construction, the construct high-decibel noise that produces of underwater pile driving produces the biology lived in around this marine site and has a strong impact on, grievous injury and interference marine organisms, destruction marine ecosystems balance, how the noise effectively controlled in marine wind electric field process of construction caused by piling construction impacts, keep the balance between new energy development and ecological environment, become the problem that industry needs solution badly.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of noise vibration produced in coastal waters fluid when effectively can reduce underwater pile driving construction, cost of production is low, easily manufactures, firm and durable for offshore wind turbine foundation piling noise reduction apparatus.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of for offshore wind turbine foundation piling noise reduction apparatus, comprise steel cofferdam, described steel cofferdam outer wall is provided with noise reduction wall.
The inwall of described steel cofferdam is provided with some rectangular tubes be 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 formed by some monolithic silencing blocks are assembled.
Described monolithic silencing block is provided with inside and empties structure.
The invention has the beneficial effects as follows: steel cofferdam outer wall of the present invention is provided with noise reduction wall; the inwall of steel cofferdam is provided with the rectangular tube of band pore; in piling process; compressed air is discharged by pore; MLV curtain is formed between steel pipe pile and steel cofferdam; MLV curtain and noise reduction wall two methods is adopted to realize the noise abatement in piling process; structure is simple; easy realization; cheap; effectively can reduce the noise pollution in marine guidance piling work progress, contribute to protecting marine ecosystems, keep the balance between new energy development and ecological environment.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is noise reduction apparatus structural representation of the present invention;
Fig. 2 is noise reduction apparatus top view of the present invention;
Fig. 3 is monolithic silencing block sectional view.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of for offshore wind turbine foundation piling noise reduction apparatus, comprise steel cofferdam 11, described steel cofferdam 11 outer wall is provided with noise reduction wall 1, described noise reduction wall 1 is formed by some monolithic silencing blocks 2 are assembled, described monolithic silencing block 2 is provided with inside and empties structure 20, monolithic silencing block 2 can be block, also can be strip, noise reduction wall 1 can be designed to circle, also can be designed to square or polygon, can also make left and right two halves docking, monolithic silencing block 2 is made up of rubber, glass fiber, pelelith etc.
The inwall of described steel cofferdam 11 is provided with some rectangular tubes 33 be circumferentially arranged, described rectangular tube 33 is provided with pore 34, described rectangular tube 33 connects air compressor machine 31 by appendix 32, air compressor machine is by after air compressing, pressure-air delivers to rectangular tube 33 by appendix 32, then spray from pore 34, between steel pipe pile and steel cofferdam, form MLV curtain.
During work; noise reduction apparatus of the present invention is lifted to stake position; put between water steel cofferdam 1 and steel pipe pile and be full of seawater; compressed air is ejected between steel pipe pile and steel cofferdam by pore 34 and forms MLV curtain; these bubble curtains are as first silencing apparatus; the noise reduction wall of steel cofferdam outer wall is as second silencing means; effectively can reduce the noise vibration produced in the fluid of coastal waters when underwater pile driving is constructed; cost of production is low; easy manufacture; firm and durable, contributes to protecting marine ecosystems, keeps the balance between new energy development and ecological environment.
