Honeycomb array spoiler type sound field damping net and noise control method in offshore piling

Abstract

The invention discloses a honeycomb array spoiler type sound field damping net and a noise control method in offshore piling. The honeycomb array spoiler type sound field damping net comprises a buoyant box, a sound field damping box and a sinking box which coaxially sleeve the outside of a pile body sequentially from top to bottom. The sound field damping box comprises a plurality of cylindricalhoneycomb structure turbulent flow boxes which are coaxially arranged sequentially from top to bottom. Each honeycomb structure turbulent flow box is formed by densely laying a plurality of spoiler fins. Each spoiler fin comprises a hexagonal connecting frame, an inclined supporting frame and a turbulent flow piece. Each turbulent flow piece is in an arc shape and can rotate. The middle of each turbulent flow piece is connected with the corresponding inclined supporting frame through a tensioning and compressing spring rod. In the honeycomb array spoiler type sound field damping net, the relative position of the sound field damping box and the pile body can be fixed through the buoyant box, meanwhile the stability of the whole damping net in water is ensured, the working space is providedfor above-water construction, and the noise of piling can be passively and effectively weakened with zero energy consumption through the compound honeycomb structure turbulent flow boxes; and by meansof the sinking box, it can be ensured that the honeycomb structure turbulent flow boxes sufficiently divide a central pile base high-noise water body and an external environment water body and no noise is emitted out.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a honeycomb array spoiler-type sound field damping net and a noise prevention method during piling at sea. Background technique [0002] Since the 19th century, the development and utilization of marine resources by humans has shifted from traditional fisheries to the field of energy and resources. Some coastal countries have begun to exploit seabed coal mines, seaside placer and seabed oil. With the development of society and the advancement of science and technology, humans have begun to use offshore wind turbines and offshore drilling platforms to effectively use marine resources, and the amount of resource development and construction has increased year by year. In the development of marine resources, offshore wind power, oil and combustible ice mining It is an important part, and the construction of wind turbines, drilling wells and scientific research platforms i...

Problems solved by technology

All countries have environmental protection standards for marine environment construction, and the European Union has established relatively strict standards, but the sound-absorbing construction measures for the piling process in various countries are not perfect and effective, and some areas even find it difficult to take this standard into consideration during construction
