Abstract: A wave-direction-adaptive wave focusing type wave energy convertor with multiple water channels, comprising an energy acquisition system, an energy conversion system and a support system. Wave focusing is carried out through double water channels, so that the movement amplitude of water particles behind a box is doubled. A device is connected with a fixed pile through universal bearings, so that an opening of the device is always faced to a wave flow direction, which adapts to different seasons and water conditions, has low environmental requirements, and can be used in a wide sea area. Several coils of pretension spring compression are arranged in a winding barrel, so that a nylon rope connected to a buoy is ensured to be always in a straightened state and not derail from pulley blocks to work abnormally due to looseness whether the buoy is at a wave crest or a wave trough.
