The floater 110 is far away from the double-pulse turbine 300, the generator 200 is installed on the floater 110, so that the maintenance is convenient, but the transmission efficiency is reduced under the condition of long-distance transmission, so that the generator 200 system is directly installed on the double-pulse turbine 300, the upper connecting rod and the lower connecting rod do not transmit mechanical energy, and the upper connecting pipe and the lower connecting pipe only pass through a cable to transmit electric energy converted by the generator 200 system.
