专利汇可以提供Method and apparatus for surface regeneration of underwater structure专利检索，专利查询，专利分析的服务。并且PURPOSE: To make the effective shooting range of jet water markedly long and to efficiently remove seaweeds or shells harmful and useless to a fish farm by providing a structure for ejecting an air jet stream from the periphery of high speed jet water in each nozzle of a support.
CONSTITUTION: Each nozzle 9 communicates with a water passage 10 and an air passage 11 and high speed jet water is ejected from the center of said nozzle and compressed air is ejected from the periphery thereof. By this method, the effective shooting range of a water jet stream in water can be extended. Further, by rotating the whole of a support 1 equipped with a plurality of the nozzles 9, the water jet stream nozzles 9 are effectively utilized to efficiently remove seaweeds or the like from a fish farm.
