Abstract

A floating wind power generation device comprises: a main buoyant body which has buoyancy and a space portion provided in the center; an auxiliary buoyant body which has buoyancy and is connected to the main buoyant body by being inserted into the space portion of the main buoyant body; a plurality of wind power generators which are vertically provided on top of the auxiliary buoyant body and generate power; a location control means which is connected to the main buoyant body and controls the location of the main buoyant body; an oscillation inhibiting means which is connected to the main buoyant body and enables the main buoyant body to maintain an equilibrium state by absorbing the sea waves; and a dock connection unit which is connected to the main buoyant body and enables a ship to lie at anchor on the sea.

First claim

The invention claimed is:

1. A floating wind power generation device comprising:
a main buoyant body which has buoyancy, so as to float on the sea, and has a space portion provided in the center;
an auxiliary buoyant body which is connected to the main buoyant body by being inserted into the space portion of the main buoyant body, the auxiliary buoyant body including a plurality of plate-shaped individual structures having buoyancy which are disposed in parallel and are connected to each other;
a plurality of wind power generators which are vertically provided on top of the auxiliary buoyant body and generate power;
a location control means which is connected to the main buoyant body and controls the location of the main buoyant body;
an oscillation inhibiting means which is connected to the main buoyant body and enables the main buoyant body to maintain an equilibrium state by absorbing the sea waves; and
a dock connection unit which is connected to the main buoyant body and enables a ship to lie at anchor on the sea,
wherein the oscillation inhibiting means comprises:
a plurality of first absorption plates which are spaced apart from each other in the circumferential direction of the main buoyant body and each have one end rotatably coupled to the main buoyant body in a vertical direction by means of a hinge;
a plurality of second absorption plates rotatably hinge-coupled to the other end of each of the plurality of first absorption plates in the vertical direction; and
a connection wire having a structure of a ring that connects the second absorption plates.

2. The floating wind power generation device of claim 1 , wherein the location control means comprises:
a plurality of support frames which comprise a pair of basic bar members disposed to face each other at one side and the other side thereof and a support bar connecting the pair of basic bars and which are spaced apart from each other in a circumferential direction of the main buoyant body;
a motion plate which has an airfoil cross-sectional structure and of which both sides are rotatably connected to the basic bar members by being disposed between the basic bar members;
a plate-shaped linkage plate having elasticity, which is connected to one end of the motion plate by being disposed between the basic bar members and has both sides on which a connection bar is formed;
a rotation power generator which is connected to the connection bar at one side of the linkage plate by being installed at the basic bar member at one side thereof and produces power by rotation of the linkage plate that makes a vertical motion due to the waves on the sea;
a rotation driving unit which is connected to the connection bar at the other side of the linkage plate installed at the basic bar member at the other side thereof, is electrically connected to the rotation power generator and generates a driving force by power supplied from the rotation power generator so that the linkage plate is rotated; and
a driving controller which is electrically connected to the rotation power generator and the rotation driving unit and controls whether power produced by the rotation power generator is supplied to the rotation driving unit.

3. The floating wind power generation device of claim 2 , wherein the rotation power generator comprises:
a power generation gear box comprising a first crank shaft having one end coupled to a first rotation shaft and the other end on which a first fly wheel is disposed and a first link member having one end coupled to the first fly wheel and the other end connected to the connection bar at one side of the linkage plate; and
a power generator which is connected to the first rotation shaft of the power generation gar box and produces power by a rotational force of the first rotation shaft.

4. The floating wind power generation device of claim 2 , wherein the rotation driving unit comprises:
a driving gear box comprising a second crank shaft having one end coupled to a second rotation shaft and the other end on which a second fly wheel is disposed and a second link member having one end coupled to the second fly wheel and the other end connected to the connection bar at the other side of the linkage plate;
a deceleration gear box connected to the second rotation shaft of the driving gear box; and
a driving motor connected to the deceleration gear box.

5. The floating wind power generation device of claim 1 , wherein the dock connection unit comprises:
a bar-shaped connection arm connected to an outside surface of the main buoyant body to protrude in a direction of an outside of the main buoyant body; and
a transportation rail which is installed at a top surface of the connection arm in a longitudinal direction and enables articles to be unloaded from the ship to be transported.

6. The floating wind power generation device of claim 1 , wherein each of the wind power generators produces a total amount of power of 1 to 1.2 GW, and a substation facility connected to the wind power generators is further installed on top of the individual structures of the auxiliary buoyant body.
