Abstract

An AUV/UUV docking station is provided that is tethered to a wave energy converter that is in turn tethered to a flotation buoy. The AUV/UUV docking station has a cone for directing an AUV/UUV into a charging dock that is rotatable between a horizontal docking position and a vertical charging position such that in the vertical position the docking station and docked AUV/UUV have a reduced profile so as not to interfere with the operation of the wave energy converter. Energy from the wave energy converter is directed to the dock to charge the AUV/UUV.

Claims (34)

1 . A docking system for an underwater vehicle comprising:

a support frame;

a cylinder for receiving an AUV/UUV to be charged, said cylinder pivotally attached to said support frame and movable between a horizontal docking position and a vertical charging position;

a cone affixed to a bottom end of the cylinder; and

a weight movable along a length of the cylinder;

wherein said weight is selectively movable from one end of the cylinder to an opposing end of the cylinder to change a center of gravity of the cylinder and effect pivoting of the cylinder between said horizontal and vertical positions.

2 . The docking system of claim 1 , said frame further comprising:

at least two vertical frame members; and

a horizontal member connecting a lower end of said two vertical frame members,

wherein said cylinder in said horizontal docking position rests against said horizontal member.

3 . The docking system of claim 1 , further comprising:

a charging port on an interior of said cylinder.

4 . The docking system of claim 3 , wherein said charging port is a direct connection type charging port.

5 . The docking system of claim 3 , wherein said charging port is an inductive charging port.

6 . The docking system of claim 3 , further comprising:

an electrical connection extending from said charging port to a mooring tether at a top end of said support frame.

7 . The docking system of claim 1 , wherein said docking system is attached to a wave energy converter device by a mooring tether, said docking system including a charging port on an interior of said cylinder and an electrical connection extending from said charging port to an output on said wave energy converter.

8 . A charging apparatus for an underwater vehicle comprising:

a wave energy converter device;

a docking station mechanically and electrically coupled to said wave energy converter device,

said docking station comprising:

a support frame;

a cylinder for receiving an AUV/UUV to be charged, said cylinder pivotally attached to said support frame and movable between a horizontal docking position and a vertical charging position;

a cone affixed to a bottom end of the cylinder; and

a weight movable along a length of the cylinder;

wherein said weight is selectively movable from one end of the cylinder to an opposing end of the cylinder to change a center of gravity of the cylinder and effect pivoting of the cylinder between said horizontal and vertical positions.

9 . The charging apparatus claim 8 , said frame further comprising:

at least two vertical frame members; and

a horizontal member connecting a lower end of said two vertical frame members,

wherein said cylinder in said horizontal docking position rests against said horizontal member.

10 . The charging apparatus claim 8 , further comprising:

a charging port on an interior of said cylinder, said charging port electrically coupled to said wave energy converter.

11 . The charging apparatus claim 10 , wherein said charging port is a direct connection type charging port.

12 . The charging apparatus claim 10 , wherein said charging port is an inductive charging port.
