Submersible tidal current energy power generation device

The invention discloses a submersible type tidal current energy power generation device which comprises a fusiform floating body. The number of the elastic anchoring systems is two, and the two elastic anchoring systems are arranged at the front end and the rear end of the fusiform floating body correspondingly; the buoy assembly is fixedly connected to the top of the fusiform floating body; and the number of the horizontal shaft tidal current energy water turbines is two, and the two horizontal shaft tidal current energy water turbines are symmetrically arranged on the two sides of the fusiform floating body. According to the invention, the stable suspension state of the fusiform floating body in water is ensured by virtue of the elastic mooring system and the buoy arranged on the water surface; water flow impacts the horizontal shaft tidal current energy water turbines on the two sides of the fusiform floating body for power generation. And then the electric energy is transmitted to the outside of the syste
