专利汇可以提供Water intake device专利检索，专利查询，专利分析的服务。并且PURPOSE:To prevent the occurrence of vortex flow in a pump as well as permit the sending of water to the other pit without power by a method in which water is sent to a pit other than an intake port by utilizing the static head of water and the water suction speed of a pump while preventing the occurrence of vortex flow during the water circulation period by the pump. CONSTITUTION:A water-circulating pump 1 is actuated, and sea water or fresh water deprived of contaminants through a travel screen 2 and a fine screen 3 is taken by a suction port 11 with a butterfly valve, provided to a water conveyance duct 10. The water is sent to a various purpose water pit utilizing the head of water and the speed of the water-circulating pump 1. suction ports are provided to each waterway, a water conveyance duct 10 is supported by a support bar 13 hung down from an intake cover 12, and the butterfly valve 11 of the suction port is opened or closed by a handle 14 above the intake port. By this, the occurrence of vortex flow in the pump can be prevented and also water can be sent to the various purpose water pit without power.，下面是Water intake device专利的具体信息内容。
