Flexible Wave Compensation Platform Mechanism

Abstract

The present invention discloses a flexible wave compensation platform mechanism. The mechanism comprises a chassis installed on a ship or offshore operation platform, a support platform movably connected to the chassis, and three compensation components arranged uniformly around the chassis between the chassis and the support platform. When the support platform undergoes displacement due to wave motion, the three compensation components apply different tension forces to the support platform to satisfy the displacement in the opposite direction to the displacement of the support platform, keeping the support platform level to compensate for its wave motion. Compared with the prior art, the present invention enables the wave motion of the support platform to be flexibly compensated, making the compensation more accurate and stable.
