  • Publication number: 20210131397
    Abstract: A water-flow power generating apparatus for generating electricity by a force of a water flow in water includes a main body including one rotor configured to rotate by a force received by blades from a water flow, a generator generating electricity by a rotation force of the rotor, and a pod accommodating the generator; a mooring cable for mooring the main body to a bottom of water; and a connecting mechanism for connecting the mooring cable to the pod. The mooring cable and the pod are relatively movable along a vertical plane orthogonal to a center axis of the rotor. A center of buoyancy of the apparatus main body is on a vertical upper side with respect to a center of gravity of the apparatus main body.

  • Patent number: 10731623
    Abstract: A water-flow power generating apparatus includes a blade, a rotary part, a power generating unit, a nacelle, and a bearing unit. The blade rotates with power of a water flow. The rotary part is connected to the blade and rotates integrally with the blade. The power generating unit is connected to the rotary part and generates electricity with a rotation force of the rotary part. The nacelle covers the power generating unit, forms a boundary between an inner space in which the power generating unit is disposed and an underwater in which the blade is disposed. The bearing unit supports the rotary part. The bearing unit includes a thrust bearing disposed in the inner space and supporting the rotary part from an axial direction of the rotary part, and a journal bearing disposed between the nacelle and the blade and supporting the rotary part from a radial direction.

  • Patent number: 6767166
    Abstract: A motion reduced floating structure includes a main hull structure and a wave damping structure connected with the main hull structure. The wave damping structure may include a back board, a lower horizontal board and vertical members. The back board is connected with the main hull structure, and the lower horizontal board is connected with a lower portion of the back board to extend in a horizontal direction and is under a seawater surface in case of mooring. The vertical members are connected with the lower horizontal board and the back board. A vertical direction hole is provided for the lower horizontal board.
