Abstract: A buoyant kinetic energy apparatus, used for solving the problem that the kinetic energy generation efficiency of an existing buoyant kinetic energy apparatus is low, comprises: a base (1), provided with a liquid tank (11); a rotor (2), provided with a rotary body (21) and a shaft part (22), the shaft part (22) combining the rotary body (21) and the liquid tank (11), and the rotary body (21) being rotatably arranged in the liquid tank (11) by means of the shaft part (22); a float (3), telescopically arranged on the rotary body (21); and a telescoping control module (4), arranged in the liquid tank (11) and controlling the float (3) to telescope relative to the rotary body (21) when the rotary body (21) rotates.

Abstract: A buoyancy-driven kinetic energy generating apparatus includes a base having a tank. A rotor includes a rotor body rotatably received in the tank. At least one float telescopes relative to the rotor body to a rotating axis of the rotor body while the rotor body rotates. A telescopic movement control module is mounted in the tank and controls the telescopic movement of the at least one float. A method generates kinetic energy by using the buoyancy-driven kinetic energy generating apparatus. The method includes filling a liquid into the tank to provide the rotor body with a pre-buoyancy and controlling the at least one float to telescope relative to the rotor body, causing a change in local buoyancy of the rotor body to imbalance the rotor body and to cause rotation of the rotor body about the rotating axis.

Abstract: An apparatus for wave energy harnessing includes at least one slide shaft, a buoyant unit, an energy-transmitting unit, and a rotate unit. The slide shaft is firmly mounted on the seabed. The buoyant unit is movably engaged with the slide shaft and has a reservoir and an adjusting board, so as to control the vertical position of the buoyant unit relative to sea level. The energy-transmitting unit is mounted on the buoyant unit. The rotate unit rotatably engages with the energy-transmitting unit and connects with an energy-transfonning unit through a transmission shaft. Thereby, the buoyant unit is driven by waves to vertically slide along the slide shaft, the energy-transmitting unit rotates the transmission shaft of the rotate unit, and, thus, the energy-transforming unit generates power.

Abstract: A wave energy power generating apparatus includes a fixed base, a buoyant float unit and at least one gearing mechanism. The fixed base has a slide shaft mounted thereon for connecting with the buoyant float unit. The buoyant float unit includes a buoyant float slidably connected with the slide shaft, and at least one rack mechanism formed with a pair of rack members. The gearing mechanism includes a transmission shaft, and a pair of one-way gears connected with the transmission shaft and engaged with the rack members. The rack members can drive the one-way gears to rotate the transmission shaft in a single predetermined direction when an upward or downward movement of the buoyant float unit occurs.
