Tide energy and wave energy coupled power generation and freshwater production system

The present invention discloses a power generation system and the freshwater flow system coupling and wave energy, comprising a pillar, with a buoy wave energy collecting apparatus, means to capture the trend, the fuel tank, hydraulic energy storage system, manufactured by means of fresh water, power generating device . Pillar is fixed to the seabed, the wave energy collecting means mounted in the base column, the trend capture device is mounted on the float. Wave energy collection means for the fuel tank and the fuel supply device can capture trends. Wave energy collection means to capture the fluid flow and the output of the device is connected to the input of a hydraulic fluid system can be stored, respectively, the output end of the hydraulic fluid energy storage system is connected to the fluid generator and the input device are made fresh . The present invention can simultaneously use two kinds of wave and tidal current energy energy, more stable single wave energy or energy supply can become the trend with respect to electricity while still fresh prepared, so that full use of energy, minimize the energy storage, thereby reducing energy waste.
