Kinetic energy recovery wind-wave integrated system

A kinetic energy recovery wind-wave integrated system comprising:

• a semi-submersible platform with an installation groove;
• a fan arranged on the semi-submersible platform;
• a wave energy device arranged inside the installation groove of the semi-submersible platform, wherein the wave energy device comprises:
• a sliding rod;
• at least two counterweight blocks, each one is fixed on either ends of the sliding rod;
• a shell configured to be received within the installation groove, wherein the shell is configured to receive a PTO system, wherein:
• the PTO system comprises an active controller and a permanent magnet synchronous linear motor comprising a stator and a mover;
• the stator is fixedly connected to the shell;
• the mover is fixed on the sliding rod;
• the at least two counterweight blocks are disposed outside the permanent magnet synchronous linear motor;
• one of the at least two counterweight blocks is connected to top portion of the shell via a plurality of springs, wherein one end of the plurality of springs are connected to the one of the at least two counterweight blocks and another end of the plurality of springs are connected to the top portion of the shell;
• and
• at least two limiters, wherein one limiter is disposed towards interior of the shell and fixedly connected to the top portion of the shell and the other limiter is disposed towards the interior of the shell and fixedly connected to bottom portion of the shell;
• wherein the sliding rod is disposed in the shell along an axial direction of the shell;
• one end of the sliding rod passes through the one limiter and the top portion of the shell and is connected to the one limiter and the top portion of the shell in a sliding manner, the other end of the sliding rod passes through the other limiter and the bottom portion of the shell and is connected to the other limiter and the bottom portion of the shell in a sliding manner;
• and
• a battery, wherein the battery is configured to store electrical energy converted by the wave energy device, wherein:
• the active controller is electrically connected to the limiters and the battery;
• the wave energy device is configured to operate in any one of a working mode or a survival mode using the electrical energy stored in the battery wherein:
• in the working mode, the wave energy device is configured to turn on a power generation mode of the wave energy device;
• and
• in the survival mode, the active controller in the wave energy device is configured to turn off the power generation mode of the wave energy device;
• and
• the at least two limiters are configured to mechanically limit movement of the at least two counterweight blocks during the working mode and the survival mode of operation of the wave energy device.
