High-speed light boat stern part wave-compressing apparatus

The invention discloses a high-speed light boat stern part wave-compressing apparatus comprising a plurality of wave-compressing plates, a plurality of connection rods and a wave-compressing plate adjusting device. The middle of the inner side of each wave-compressing plate is fixedly connected with the external end of each connection rod in a vertical way; the inner ends of the plurality of connection rods are fixedly connected with a shaft sleeve in a radial and vertical way; the wave-compressing plate adjusting device is disposed in a stern transom plate and equipped with a stepping motor, a horizontal transmission shaft and two bearing seats; the external end of the horizontal transmission shaft is fixedly connected with the shaft sleeve; the stepping motor is supported in an internal supporting seat; one end of the internal supporting seat is perpendicularly fixed on the inner side surface of the stern transom plate; one end of an external supporting seat is vertically fixed on the external side surface of the stern transom plate; and two ends of the horizontal transmission shaft are respectively supported on the external supporting seat and the internal supporting seat via the bearing seats. The high-speed light boat stern part wave-compressing apparatus is simply structured and has light weight and simple operation; load of the high-speed light boat stern can be effectively reduced; and various functions of a normal wave-compressing apparatus can be met and unfavorable effects on quickness and operability upon the high-speed light boat at states of reversing, turning over, sliding and topspeed can be reduced.
