Abstract
The invention relates to a high efficiency waterwheel apparatus having track-type blades and a track-type blade set thereof, which includes at least one track disk, a plurality of moving elements and a plurality of blades. The track disk has at least one track surrounding a central axis of the track disk. The moving elements move in the track. The blades are connected to the moving elements. The blades are pushed by water flow to revolving around a central axis. The moving elements connected to the blades are guided by a track so that the blades have different angles while revolving to different positions of the track. Thus, the blade set rotate at a variable angular velocity. When the track-type blade set is applied for power generation, the power generation efficiency is improved in a low-speed ocean current.
