LV14830B - The device for conversation of energy of sea waves or river current - Google Patents

Abstract

The invention concerns devices for transformation of the kinetic energy from the movement of waves or river current energy. The device consists of one or several modules. Each module includes wings (1) attached to an axle (2) and rotating in the bracket (3), in addition axle (2) and bracket (3) are mounted on a float (4), which is filled with water to a needed level to change the depth of the draft. There is a pulley (5) mounted on the axle (2). The rotation movement is transferred from the pulley (5) to the generator (7) and flywheel (8). Module is working efficiently only when wings are submerged into water just to the point to receive the kinetic energy from the waves. Level, to which the wings are submerged, is controlled by sensor, which, depending on the height of the waves, gives command to pump water into the float or out of it. The device for the transformation of the kinetic energy from the movement of waves consists of several modules, each additionally comprising a one way clutch (6). All the modules are flexibly connected with couplers (9) and common gear (10), which, depending on movement of waves, allow each module to move independently up and down. The first module is anchored. To convert energy of stream into electricity the module is equipped with confusers and diffusers in accordance with the velocity of the stream in which it is being placed. This significantly increases efficiency of the module when it is used for this purpose.

Description

The invention relates to energy devices for the use of kinetic energy of motion of sea waves. The object of the invention is to increase the net power available in an environmentally friendly manner.

Known state of the art

A device that converts the kinetic energy of sea waves into electrical energy is known (Patent CN101487442 A) and consists of a cylinder with wings exposed to sea waves. However, the efficiency of such a device is low because only one of the wings is in a vertical plane that is affected by the entire wave stream. All other wings are at an angle relative to the direction of the wave flow.

Known device for converting kinetic energy of sea waves into electrical energy (patent WO2010102005 A3) and consisting of a circuit conveyor with mounted plate spams. The plates, which are axially secured and capable of resting on the conveyor (at the top of the chain) in the supine position, move out of the water and move along the surface of the conveyor to the starting point to start their downward movement again. As the chain wraps around the roller, it is necessary to raise the plate to its starting position, and this force forces the chain to resist, thereby reducing the total amount of energy that can be generated.

DETAILED DESCRIPTION OF THE INVENTION

The construction (Fig. 1) consists of several modules. Each module (Figures 2, 3) consists of conveyor-type wings (1), which are fixed to the axles (2) and rotate in the bracket (3). The shaft (2) with the bracket (3) is mounted on the float (4), which can be filled with water as needed by changing the draft of the float. The pulley (5) and the one-way clutch (6) are located on the shaft (2). The rotational movement from the pulley (5) is transmitted to the generator (7) and the flywheel (8).

Each module is interconnected movably with a connector (9) and a common gear (10) allowing each module to move independently up / down depending on the wave motion. The first module is anchored.

The control system includes an echo-probe, which measures the distance from the wave ridge and depression to the sea floor, and the computing unit calculates half the wave amplitude (distance from the wave depression to the ridge) and compares it to the blade draft controlled by the blade draft sensor. In the event of a discrepancy between these values, the control system gives a command to switch on or off the pump which supplies or pumps the water to / from the floats. In this way, the most efficient blade work is achieved, because only at the top of the wave amplitude, water particles circularly move in the direction of the wave, bringing the working blades along.

The structure works as follows: the waves rotate the first module, which rotates the pulley (5) and the gear generator (7) and the flywheel (8). When the wave passes the first module and begins to rotate the second module, the first module stops and the pulley (3), overall gear and the one-way clutch (6) continue to rotate due to the second module. In this way, the wave travels under each module and, through the wings of subsequent modules, transmits a continuous rotational movement to the first pulley (3) and further to the generator (7) and the flywheel (8).

If the generator is transformed into a river stream for power conversion, the structure consists of a single module (Fig. 4), and since the river stream flows in one direction, a one-way clutch (6) is not required here.

A confuser (11) is used to increase the speed of the slow river stream and thus the capacity of the plant. The configurator (collector) housing (12) has cut-out windows which, together with the float (13) configuration (similar to the collector), give the module additional power.

There is a grille (14) to protect the module from floating objects.

The River Stream Generator works as follows: The confluent (11) narrows the river stream, increasing the stream speed. The float (13) has configurators (collectors) located on the sides of the float hull and directing additional power from the river stream. At the back of the case is a diffuser (15) with perpendicular to the flow edges, which also provides additional power.
