A tidal power generation device includes a container assembly and a power generation device arranged in the container assembly. A water inlet of the container assembly allows a tidal water flow to enter. An entrance guide plate of the container assembly causes the water flow to advance in the direction of the power generation device to push the power generation device's thrust plates, and thereby driving the power generation device's thrust plate traction mechanism to make a power generator of the power generation device convert kinetic energy into electrical energy. After the water flow pushes the thrust plates, it enters a pressure accumulating pool of the container assembly. Then, the water flow in the pressure accumulating pool flows to a backflow guide plate of the container assembly, and flows to a first pressure relief pool of the container assembly to continue pushing the thrust plates.

An energy conversion device for converting water energy, in some cases water energy from waves and/or a flow such as an ocean current, into electric energy, comprises at least one rotor having a rotor rotational axis, the alignment of which is in some cases fixed by a supporting frame, and a flow housing which comprises a rotor shell which surrounds the rotor radially to the rotor rotational axis.

The present invention relates to the utilization of wave energy and its conversion into operating motion of an electrical energy generating system. The system for generation of electrical energy through the conversion of aquatic wave motion includes floating bodies and a constant rotation mechanism, which converts the two-way linear motion of an inflexible transmission shaft or a flexible transmission shafts into one-way rotation of an output shaft of the constant rotation mechanism. This mechanism allows utilization of wave energy in two directions caused by the rise and fall of waves. The output shaft of the constant rotation mechanism is coupled to a force multiplier that is further coupled to a generator which generates electrical energy. Constant rotation mechanism can be driven by inflexible transmission shaft pivotally coupled to the floating bodies at one end, and the other end to an input gear of the constant rotation mechanism. Depending on the height of the wave and the wavelength, various constructions of floating bodies are used. Certain floating bodies are designed for the waves of a smaller amplitude and smaller wavelength, while other floating bodies are designed for bigger amplitude and bigger wavelength.

A displacement system for a submersible electrical system such as a tidal turbine system, the displacement system comprising a base for the turbine or related electrical components, a vessel having a buoyant body and at least three rigid legs each displaceable relative to the body between a raised and a lowered position, and in which the base is adapted to be secured to and displaceable by the three legs in order to allow the base to be deployed or retrieved from the seabed using the legs, which legs can also be utilised to raise the body of the vessel out of the water to provide a stable work platform above the deployment site.

Disclosed herein is a turret mooring system for a tidal turbine assembly 150, which increases the ratio of the torque exerted by the turret 100 relative to frictional forces between the turret 100 and the assembly 150 moored to the turret 100. In some examples, the frictional forces are reduced by the turret providing an upward force to the assembly, which also resists pitching moments. In other examples, the torque exerted by the turret 100 is increased by the use of a bifurcated mooring line 106, 108 which couples to two spaced apart attachment points 128 on a chain table 104 of the turret 100 and to a single point 114 on the water bed.
