Power generation device and power generation system using same

Abstract

The invention discloses a power generation device which comprises a wind driven generator, a hydroelectric generator, a solar generator, a first variable gear, a second variable gear, a circular flatplate, a wind plate, a floating plate, a water wheel blade, a connecting rod, anchoring equipment and a vertical shaft. According to the vertical shaft combined type floating comprehensive power generation device, two single-energy power generation devices, namely the vertical shaft fixed deflection angle type water turbine and the wind turbine with good self-starting performance, are organicallycombined, so that based on that the starting torque of the wind turbine is large, the vertical shaft water turbine is assisted to be started, and the vertical shaft water turbine can be started to rotate in any wind direction; thus, operation efficiency of water turbine is improved. The power generation device is a comprehensive power generation body and achieves diversified power generation, water and underwater all-weather power generation can be achieved at the same time, the stability and reliability of operation of a generator set are improved, the unit power generation cost is reduced, and the unit power generation efficiency is improved.
