Abstract

A floating wave power generator is capable of lifting under remote control, and includes a linear generator fixed to a seabed and a floating assembly connected with the linear generator, where the floating assembly includes a lower floating body connected with a motor of the linear generator through an anchor chain, an upper floating body connected with the lower floating body through a rigid rod and floating on the sea surface, where the upper floating body is used for collecting wave energy and controlling the buoyancy of the whole floating assembly, the lower floating body is used for assisting the upper floating body to collect wave energy and controlling a distance between the whole floating assembly and the linear generator, the motor of the linear generator is used for cutting magnetic induction lines to generate electric power according to a lift-up/down movement of the whole floating assembly.

First claim

We claim:

1. A floating wave power generator apparatus comprising:
a linear generator adapted to be affixed to a seabed, said linear generator having a rotor;
a floating assembly connected to said linear generator, said floating assembly comprising:
a lower floating body connected to the rotor of said linear generator through an anchor chain; and
an upper floating body connected to said lower floating body through a rigid rod, said upper floating body adapted to float on a sea surface, wherein said upper floating body is adapted to collect wave energy and to control buoyancy of said floating assembly and to control a distance between said floating assembly and said linear generator, wherein the rotor of said linear generator generates electric power in relation to an upward and downward movement of said floating assembly; and
a remote control system connected to said upper floating body and said lower floating body, wherein said upper floating body has an upper chamber and a lower chamber, the upper chamber having a two-way water pump mounted thereto, the lower chamber being a ballast tank, said upper floating body controlling an amount of water flowing into the ballast tank by the two-way water pump so as to control the buoyancy of said floating assembly.

2. The floating wave power generator apparatus of claim 1 , wherein water pipes are symmetrically arranged on opposite sides of the two-way water pump, the water pipes being adapted to communicate with sea water.

3. The floating wave power generator apparatus of claim 1 , wherein a water pipe is positioned at a bottom of the two-way water pump, the water pipe communicating with the ballast tank.

4. The floating wave power generator apparatus of claim 1 , wherein the two-way water pump is connected to the remote control system through a control cable.

5. The floating wave power generator apparatus of claim 1 , wherein a buoyancy of said upper floating body is greater than a weight of said upper floating body when the ballast tank has no sea water therein such that said upper floating body floats on the sea surface, wherein the buoyancy of said upper floating body is less than the weight of said upper floating body when the ballast tank is fill of sea water such that said upper floating body sinks below the sea surface.

6. The floating wave power generator apparatus of claim 1 , further comprising:
a windlass fixed to an interior of said lower floating body, said windlass being connected to the anchor chain, said windlass adapted to control a distance between said floating assembly and said linear generator by retracting or releasing the anchor chain.

7. The floating wave power generator apparatus of claim 4 , wherein said windlass is connected to the remote control system through the control cable.

8. The floating wave power generator apparatus of claim 1 , wherein said windlass controls a position of the rotor of said linear generator by retracting or releasing the anchor chain such that the rotor is positioned at a center of said linear generator when the sea surface is calm.

9. The floating wave power generator apparatus of claim 4 , wherein the rigid rod is hollow, the control cable extending through the rigid rod.
