The floating apparatus for wave power generation according to the present invention includes; a floating unit floating on a sea surface; an energy unit configured to convert a kinetic energy of the floating unit to an electric or hydraulic energy; and a transfer unit configured to transfer the kinetic energy of the floating unit to the energy unit.

A device and a method for converting wave motion energy into electric power are described. The device includes at least one support structure and a support frame to connect the floating element to the support structure. A linear element of motive power mounted on the support frame is movable with respect to the floating element and transfers motion to a motion conversion and transmission unit that converts linear motion into rotary motion, which drives kinetic energy accumulation elements and one or more electric power generators. The motion conversion and transmission unit, the kinetic energy accumulation elements and the electric power generators are all incorporated in the floating element.

The present disclosure discloses anti-drought and anti-flood by still water circulation generation. A pit (4) is dug near water (1), a water turbine (6) and a generator (7) are placed at the bottom of the pit, the water (1) on the pit (4) is released in a planned way along a water discharge pipe to drive a water turbine (6) to operate, a blade (11) and a chain (12) are meshed with an upper gear (9) and a lower gear (10), the upper gear (9) is driven by an electric motor (13) to drive the blade (11) to rotate such that the blade (11) inside a water outlet pipe moves upwards with water (1) circularly, thereby driving the generator to continuously generate power. The present invention is able to meet the power generation demand of users and is also capable of adjusting and meeting the local water consumption.

A wind turbine (11) comprising a tower structure (12, 13) and two or more rotors (1). Each rotor (1) comprises a hollow king pin (2) and a hub (4) carrying one or more rotor blades (14). The hollow king pin (2) is formed in a single cylindrical piece, and is mounted on the tower structure (12, 13). The hub (4) is rotatably mounted on the hollow cylindrical king pin (2). A generator (6) is operationally coupled to the hub (4) in such a manner that rotational movements of the hub (4) are transferred to the generator (6). The tower structure comprises a main tower part (12) being anchored, at a lower part, to a foundation structure, and at least two arms (13), each arm (13) extending away from the main tower part (12) along a direction having a horizontal component. Each arm (13) carries at least one rotor (1).

The device for conversion of wave energy into electrical energy consists of a supporting structure, the first working body, an anchor and anchor cables. The supporting structure is connected to the anchors by anchor cables, while the first working body is slidably connected to the supporting structure. The motion transformation system is firmly connected to the supporting structure and comprises rigid gears toothed with gears with rolls on one side while on the other side they are hinged to the first working body, on the other side of the gears with the rolls, rigid gears are connected at one end, while their other end is hinged to other working body. The gears with rolls are connected by shafts with a multiplier that drives the generator that further produces electricity. The device constructed in this way has the possibility of transport to the place of exploitation, because it floats stably on its own. The anchor system is transported to the place of exploitation using a transport body that also has the ability to float on its own and to submerge.

A vertical axis wind turbine includes two or more cells arranged one above the other along a vertical machine axis, in which each of the cells includes a plurality of vertical blades which are arranged within the cell distributed on a concentric circle about the machine axis and which are connected so as to be able to move together on this circle and which are rotationally fixed with a main shaft, and in which the blades in the cell are each individually mounted so as to be able to rotate about a vertical axis of rotation which in particular runs internally through them. Assigned to each of the blades are means by which the blade is made to adopt, a rotational position, about its axis of rotation, which is predetermined and can be changed at any time.
