The invention relates to a vertical shaft tidal current energy power generating device and an application thereof. The vertical shaft tidal current energy power generating device comprises a first base, a second base, a power generator, an upper impeller and a lower impeller; the power generator comprises a rotor and a stator; the rotor is assembled to a first rotating shaft; one end of the first rotating shaft is connected with the power generator and the other end of the rotating shaft is connected with the upper impeller; the other end of the upper impeller is connected with the first base through a connecting device; the lower end of the power generator is connected with a second rotating shaft; one end of the second rotating shaft is connected with the stator and the other end is connected with the lower impeller; the upper impeller and the lower impeller are SAVONIUS type blades; the blades comprise concave surface blades and convex surface blades; an overlap ratio S/D of the concave surface blades and the convex surface blades is 0.2. The vertical shaft tidal current energy power generating device has the advantages of being good in self-starting performance, improving the device stability and the working condition of the connecting device; improving the power generation efficiency and saving complex mechanical component such as a gear transmission mechanism.
