Abstract
The utility model discloses a novel offshore wind power steel pipe pile noise removing steel cofferdam device. A sulfur-free rubber sound absorption wedge layer formed in a squeezing mode is attached on the inner wall of a steel cofferdam. A spiral-arranged rubber soft pipe is arranged in the steel cofferdam. An air hole is formed in the rubber soft pipe. Compressed air enters the position between a steel pipe pile and the steel cofferdam through the rubber soft pipe to form air bubbles, the rubber soft pipe is used as a first noise removing device, and the sulfur-free rubber sound absorption wedge layer attached on the inner wall of the steel cofferdam is used as a second noise removing device. Noise vibration generated in inshore fluid during underwater piling construction can be effectively lowered, production cost is low, manufacturing is easy, firmness and durability are achieved, a marine ecosystem can be well protected, and the 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 single pile more both at home and abroad, 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 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, cost of production is low, easily manufactures, and the novel offshore wind farm of firm and durable is subdued the steel cofferdam device of steel pipe pile noise.
The utility model solves the technical scheme that its technical problem adopts:
Novel offshore wind farm is subdued a steel cofferdam device for steel pipe pile noise, comprises steel cofferdam, on described steel cofferdam inwall, be attached with one deck extrusion modling without sulphur rubber wedge absorber layer.
In described steel cofferdam, be provided with the stiffener of some longitudinal extensions.
In described steel cofferdam, be provided with some reinforcing rings.
In described steel cofferdam, be provided with the rubber hose that helical form is arranged, in described rubber hose, be provided with pore.
It is described that without sulphur rubber wedge absorber layer, without sulphur rubber sound absorption, monolithic is stacked forms by some.
The beneficial effects of the utility model are: in steel cofferdam of the present utility model, be provided with the rubber hose that helical form is arranged, in rubber hose, be provided with pore, compressed air is entered between steel pipe pile and steel cofferdam and is formed bubble by rubber hose, as first silencing apparatus, the one deck adhering on steel cofferdam inwall without sulphur rubber wedge absorber layer as second silencing means, the noise vibration producing in the fluid of coastal waters can effectively reduce underwater pile driving construction time, cost of production is low, easily manufacture, firm and durable, contribute to protect marine ecosystems, keep the balance between new energy development and ecological environment.
