The device places the power generation device on the offshore platform 102, so that on one hand, the installation is more convenient, the manpower and material resources are saved, on the other hand, the device loss caused by seawater corrosion is reduced, and the service life of the device is prolonged.
In the floating body rope wheel type wave energy device capable of being combined with the offshore platform, the oscillating buoy 101 is arranged on one side of the offshore platform 102 and moves relative to the offshore platform 102. The oscillating buoy 101 is driven by waves, generates a relative displacement with the offshore platform 102 and drives the rigid rope 103 to rotate the fixed pulley 302, thereby activating the pulley system.
