Abstract
A tidal current generator relates to a tidal current generator that can efficiently generate power by separating an on-water power generation unit and an in-water power collection unit, that allows for easy management of facilities on the water because the facilities in the water can be easily pulled up on the water even if they break, that can maximally use the flow of tides using a connection rope and a groove formed on a rotary propeller, and that can maximize efficiency by controlling the number of power connections between a rotary unit and an on-water power generator in accordance with the states of the flow of tides to prevent waste or deficit of power transmission.
Claims4
A tidal current generator comprising:
- an on-water power generation unit that is installed on the seawater to generate power through power generators;
- and
- an in-water power unit that is disposed under the seawater to support the on-water power generation unit and transmit power to the power generators using the flow of tides as a power source,
- wherein the in-water power unit includes:
- one or more supports that support the bottom of the on-water power generation unit on the sea bottom;
- one or more rotary bars that are installed perpendicular to the surface of the seawater with the upper ends exposed to the on-water power generation unit to transmit torque to the power generators;
- propeller assemblies that each include multiple propellers spaced a predetermined angle apart from one another on sides of the rotary bars to be rotated by the flow of tides;
- a bottom support that maintains balance of the rotary bars by connecting sides of the lower ends of the rotary bars and sides of the supports;
- and
- lifters that are disposed at the joints between the supports and the bottom support so that the rotary bars can be moved up and down along the supports,
- wherein multiple power generators of the on-water power generation unit can be connected to one rotary bar, and power can be disconnected between a specific power generator and the rotary bar by power disconnection members, if necessary.
