Abstract
The invention discloses the steel cofferdam device of a kind of offshore wind farm abatement steel pipe pile noise, steel cofferdam, steel cofferdam inwall is attached with one deck extruded without sulphur rubber wedge absorber layer, the rubber hose of helical form arrangement is provided with in steel cofferdam of the present invention, rubber hose is provided with pore, compressed air is entered between steel pipe pile and steel cofferdam by rubber hose and forms bubble, as first silencing apparatus, one deck that steel cofferdam inwall adheres to without sulphur rubber wedge absorber layer 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, contribute to protecting marine ecosystems, keep the balance between new energy development and ecological environment.
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, domestic and international offshore wind turbine foundation many employings single pile, tripod, the base forms such as jacket, and these base forms mostly 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, the steel cofferdam device of the novel offshore wind farm abatement steel pipe pile noise of firm and durable.
The technical solution adopted for the present invention to solve the technical problems is:
A steel cofferdam device for offshore wind farm abatement steel pipe pile noise, comprises steel cofferdam, described steel cofferdam inwall is attached with one deck extruded without sulphur rubber wedge absorber layer.
The stiffener of some longitudinal extensions is provided with in described steel cofferdam.
Some reinforcing rings are provided with in described steel cofferdam.
Be provided with the rubber hose of helical form arrangement in described steel cofferdam, described rubber hose is provided with pore.
Describedly to absorb sound that monolithic is stacked is formed without sulphur rubber wedge absorber layer without sulphur rubber by some.
The invention has the beneficial effects as follows: the rubber hose being provided with helical form arrangement in steel cofferdam of the present invention, rubber hose is provided with pore, compressed air is entered between steel pipe pile and steel cofferdam by rubber hose and forms bubble, as first silencing apparatus, one deck that steel cofferdam inwall adheres to without sulphur rubber wedge absorber layer 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, contribute to protecting marine ecosystems, keep the balance between new energy development and ecological environment.
