Abstract
The invention discloses a device for abating offshore draught fan foundation piling noise. The device comprises a steel cofferdam, wherein the outer wall of the steel cofferdam is provided with a noise reduction wall, the inner wall of the steel cofferdam is provided with a rectangular tube with air pores, in the piling process, the compressed air is discharged through the air pores, multiple layers of air bubble curtains are formed between a steel tube pile and the steel cofferdam, and the noise in the piling process can be reduced by adopting the double means of the multiple layers of air bubble curtains and the noise reduction wall. The device is simple in structure, easy to realize and low in cost, the noise pollution in the offshore piling construction process can be effectively reduced, the ocean ecological system can be protected, and the balance of the novel energy development and the ecological environment can be maintained.
Description
Technical field
The present invention 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.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides and a kind ofly can effectively reduce the noise vibration producing in the fluid of underwater pile driving when construction coastal waters, cost of production is low, easily manufacture, 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 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 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 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.
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;
