Embodiments of the inventions

As shown in the drawings, the electric device from the ocean waves of the present invention includes a float 2, the electric generator 3, the turbine wheel 4 and the accelerator Wodan the th stream 5. The electric generator 3 is fixed on the float 2, the water intake 8 with vertically directed the receiver box is located at the base of the float 2, the water intake 8 is connected in a fixed position with the float 2, the vertical plate 81 is located on the side of the water intake 8 and is designed to prevent its rotation. The rotating shaft 1, which rotates in coordination with the float 2 and the accelerator of the water stream 5, is located between the accelerator water flow 5 and the float 2, the upper end of the rotating shaft 1 passes through the float 2 and is connected with the rotor of the electric generator 3, the lower end of the rotating shaft 1 passes through the water flow accelerator 5 and is connected in a fixed position with the turbine wheel 4, a channel for passing water stream 51 is located in the water flow accelerator 5 and serves for the formation of a high-speed water flow, thereby causing the turbine wheel 4 in a rotational movement in one direction. Since the turbine wheel 4 induces the electric generator 3 for generating electric power through a rotating shaft 1, the driving force having the same direction as the rotation direction of the rotating shaft 1, has an effect on the electric generator 3 as the vertical plate 81, which is located on the side surface is different recipient 8, immersed in sea water, the driving force acting on the electric generator 3 is transmitted to the recipient 8. Since the rotation of the vertical plate 81 is necessary to overcome the resistance of the sea water, the resistance to rotation of the vertical plate 81 is designed to be much larger than the driving force acting on the electric generator 3 during the generation of electricity, which ensures the absence of rotation of the housing 30 during power generation by the electric generator 3.

Three versions of the invention, the rotating shaft 1 is a vertically situated a long rod, and the water flow accelerator 5 is a vertically positioned cylinder. The float 2 is quite large, so it is always on the surface of the water during the wave process. Float 2 includes the upper pressure plate 21, the lower pressure plate 23 and the floating insert 22 that is located between the plates. The upper clamping plate 21, the lower pressure plate 23 and the floating insert 22 is connected in fixed position to each other. Numerous connecting straps 24 are located at the base of the lower pressure plate 23 and the base connecting straps 24 are connected in a fixed position with the base is m of water intake 8. Mounting bracket 9 is located on the upper surface of the upper pressure plate 21 of the float 2, one end of the mounting bracket 9 is connected in a fixed position with the upper pressure plate 21 and the other end of the mounting bracket 9 is connected in a fixed position with the housing 30 of the electric generator 3.

Numerous blades 41 are evenly distributed on the side surface of the turbine wheel 4 and the blade 41 is a smooth arcuate plate. The accelerator of the water flow 5 is located above the turbine wheel 4, a channel for passing water stream has a spiral shape and the inner diameter of the channel for the passage of the water flow 51 gradually decreases from its input to output. The entrance channel for the passage of the water flow 51 forms an inlet for the water 52 in the upper surface of the accelerator of the water flow 5, and the output channel for the passage of the water flow 51 forms the water outlet 53 on the lower plane of the accelerator of the water flow 5. The water outlet 53 is the deviation from the center of the water flow accelerator 5 and the inlet for the water 52 is significantly more outlet openings for water 53. As the inlet for the water 52 is significantly more outlet openings for water 53 and an inner diameter of the channel for the passage of the water flow 51 gradually the mind is leetse, sea water in the channel for the passage of the water flow 51 forms a high-speed flow in the outlet for water 53, which has an impact on the blade 41 of the turbine wheel 4 and causes the rotating shaft 1 in a rotational movement in a clockwise direction, thereby generating energy.

The second water flow accelerator is located under the turbine wheel 4, the lower end of the rotating shaft is extended and passes through the second water flow accelerator 6 and the channel for the passage of the water flow 61 is located in the second water flow accelerator 6 and serves for the formation of a high-speed water flow, thereby causing the turbine wheel 4 in a rotational movement in one direction. The channel for the passage of the water flow 61 has a spiral shape, the inner diameter of the channel for the passage of the water flow 61 gradually decreases from its input to output, input channel for the passage of the water flow 61 forms a second inlet for water 62 to the lower surface of the second accelerator water flow 6, the output channel for the passage of the water flow 61 forms a second outlet for water 63 on the upper surface of the second accelerator water flow 6, the second the water outlet 63 is the deviation from the center of the second accelerator water flow 6, and a second inlet for the odes 62 substantially greater than the second exhaust holes for water 63. Because the second inlet for the water 62 is substantially greater than the second outlet for water 63 and an inner diameter of the channel for the passage of the water flow 61 gradually decreases, the sea water in the channel for the passage of the water flow 61 forms a high-speed stream in the second exhaust hole for water 63, which has an impact on the blade 41 of the turbine wheel 4 and causes the rotating shaft 1 in a rotational movement in a clockwise direction, thereby generating energy.

As shown in FIGURE 1-7, in the first embodiment of the invention, the channel for the passage of the water flow 51 is located in the water flow accelerator 5, and a channel for the passage of the water flow 61 is located in the second accelerator water flow 6. The rotating shaft 1 is connected in a free position with the accelerator of the water flow 5 and the second water flow accelerator 6, the locking sleeve 11 is located on the rotating shaft 1 and is intended to prevent axial movement of the accelerator of the water flow 5 and the second water flow accelerator 6. Thus, in the process, the rotating shaft 1 can rotate in coordination with the water flow accelerator 5 and the second water flow accelerator 6 and at the same time move in the direction up and down the water flow accelerator 5 and the second uskoritel the water flow 6. Pair limiter 64 is located on the side of the water flow accelerator 5 and the second water flow accelerator 6 and serves to obstruct their rotation. Pair limiter 64 is designed to address resistance provided by high-speed water flow generated in the accelerator of the water flow 5 and the second water flow accelerator 6, and also to prevent rotation of the accelerator of the water flow 5 and the second water flow accelerator 6, thereby increasing the conversion efficiency.

The principle of operation of the first variant embodiment of the invention is as follows.

In the first phase, the float 2 moves upward together with the wave, the turbine wheel 4 rises in fixed water layer, the flow of sea water passes through the inlet opening for water 52, a channel for passing water stream 51 and the water outlet 53 in the accelerator of the water flow 5, while the outlet for water 53 is formed of high-speed water stream, which moves much faster than the flow in the inlet hole of the water 52. High-speed water flow affects the turbine wheel 4 and causes the rotating shaft 1 in a rotational movement in a clockwise direction, thereby the first phase of generating energy. At this time, the second accelerator water flux is and 6 is in an unusable state. During the ascending movement of the float 2, the top is uneven. Upon reaching the top of the wave accelerator of the water flow 5 stops the upward movement in still water layer, the turbine wheel 4 by inertia continues its rotation. At this time, the rotating shaft 1 continues its rotation. Then under the influence of gravity, the float 2, the water intake 8 located thereon, and the water in the water intake 8 enter the second phase, together with the descent of the waves.

In the second phase of the accelerator of the water flow 5 is in an unusable state. The flow of sea water passes through the second inlet for the water 62, a channel for the passage of the water flow 61 and the second the water outlet 63 in the second water flow accelerator 6, while in the second the outlet for water 63 is formed of high-speed water stream, which moves much faster than the flow from the second inlet opening for water 62. High-speed water flow affects the turbine wheel 4 and causes the rotating shaft 1 in a rotational movement in a clockwise direction, thus comes the second phase of generating energy. During the descent movement of the float 2 down is uneven. Upon reaching the bottom of the second wave accelerator water flow 6 stops the downward movement in still water layer, tour the other wheel inertia continues its rotation. After this, the invention again rises with the wave and cycle power generation. The result is that in the time of ascent and descent of the invention the rotating shaft 1 rotates continuously in a clockwise direction, thus preventing the loss of energy during the rotation of the rotating shaft 1 in different directions.

Operation of the invention occurs in the ocean. The object located at a certain depth near the surface of the water, produces a swimming motion with the wave and is the layer waves. The object is motionless water layer, if it is located at a certain depth under water, where the water is stationary. When using the invention, the float 2 is located above sea level and on the level of the waves, float 2 produces a swimming motion up and down with the wave. The turbine wheel 4, the water flow accelerator 5 and the second water flow accelerator 6 are fixed aqueous layer. Thus, the invention uses the motion of ocean waves and converts the wave energy into mechanical kinetic energy and then to mechanical kinetic energy into electrical energy. As the float 2 is located on the surface of the water, the rotating shaft 1 and the electric generator 3 are arranged vertically, the turbine wheel 4, the accelerator vodnogospodarska 5 and the second water flow accelerator 6, supplying energy, are below sea level, and the electric generator 3 is located above sea level, this prevents the electric generator 3 and its components from the corrosive effects of sea water and increases its service life.

In practice, the rotating shaft 1 carries out its clockwise rotation, it is also possible to use the rotation of the rotating shaft 1 a counterclockwise direction by changing the direction of the spiral-shaped channel for passing water stream 51 and a channel for the passage of the water flow 61, while the principles of the invention remain unchanged. In the use and accommodation in a specific area on the sea surface numerous electric devices from ocean waves, the amount of electricity generated by all devices is collected and transmitted to shore for further processing, while the accumulation of power all devices can be implemented using a floating frame. To the electric power accumulation is also possible first processing power of each device, and then its accumulation, or the accumulation of power all devices, then its processing, or ionization of the surrounding water, resulting in a generated hydrogen, the cost is transferred to shore for further use.

As shown in FIG and 9, in the second embodiment of the invention two channels for the passage of water flows 51 is located in the water flow accelerator 5 and the inlet water 52 and an outlet for water 53 corresponding to the channels for the passage of water streams 51, further improve the conversion efficiency.

Two channel for the passage of water streams 61 are located in the second water flow accelerator 6 and the second inlet for water 62 and second outlet openings for water 63 corresponding to the channels for the passage of water flows 61, further improve the conversion efficiency. The rotating shaft 1 is connected in a free position with the accelerator of the water flow 5 and the second water flow accelerator 6, the locking sleeve 11 is located on the rotating shaft 1 and is intended to obstruct axial movement of the accelerator of the water flow 5 and the second water flow accelerator 6. Thus, in the process, the rotating shaft 1 can rotate in coordination with the water flow accelerator 5 and the second water flow accelerator 6 and at the same time to move up and down the water flow accelerator 5 and the second water flow accelerator 6. Numerous paired delimiters, 64 are located on the side of the water flow accelerator 5 and Vtorov the accelerator water flow 6. In the second embodiment of the invention in addition to adding channels passing water stream 51 or channels passing water flow 61, numerous groups of accelerators water flow 5 is located on the lower end of the rotating shaft 1 at a certain interval. The mechanism of generating power (not shown), consisting of the turbine wheel 4 and the second water flow accelerator 6, significantly increases the conversion efficiency of the present invention.

As shown in FIGURE 10, in the third embodiment of the invention one or more channels for the passage of water streams can be located in the water flow accelerator 5 and the second water flow accelerator 6 (not shown). The rotating shaft 1 passes through the water flow accelerator 5 and the second water flow accelerator 6 rotatably. The water flow accelerator 5 and the second water flow accelerator 6 is connected in a fixed position with the receiving water 8 by means of the coupling casing 7. Since the vertical plate 81, which is located on the side surface of the specified recipient, blocking its rotation, the water flow accelerator 5 and the second water flow accelerator 6 is not able to rotate, thus rotating water flow accelerator 5 and the second water flow accelerator 6 takes a severe toll is conducted on the effectiveness of the conversion.

SUBSTANCE: present invention pertains to hydraulic power development. A support arm with a hinge, enabling rotation and fixing the water pipeline in the direction of flow of water, allows for using the power installation as a flow power installation or as a wave power installation. Functional capabilities of the power installation are widened due to use of water pipelines with orthogonal turbines and an electric power generator under water on the support arm. The amount of electrical power generated can also be increased due to that, the blades are oriented in opposite directions for rotation of orthogonal turbines in opposite, unchanged directions, independent of the direction of flow through the orthogonal turbines. The inductor coil of the electric power generator is immoveable, has two-directional operation and is between neighbouring short-circuited rotors, each connected to its axle of the orthogonal turbine. The short-circuited rotors rotate in opposite directions, are fitted with small clearances from the inductor coil and are fixed using lining made from material with low sliding friction. As a result, there is increased efficiency of using energy of water passing through the flow part of the convergent-divergent water pipeline.

EFFECT: wider functional capabilities of a power installation with orthogonal turbines.
