Description

MARINE WAVES ENERGY SYSTEM

Technical field

The invention relates to a system of receiving energy from the sea waves and will find application in the production of clean electricity.

BACKGROUND OF THE INVENTION

It is known that tidal waves and wind waves on the surface of water basins carry a huge amount of kinetic energy, which, if converted to electricity, can improve the environmental performance of the environment in which we live.

There are numerous technical solutions for extracting electricity from the sea waves. A marine wave generator [US 20100026000A1] is known, wherein interconnected floating or partially submerged hinges are anchored unilaterally, with mobile connections provided with a stator of an electric generator, and a second electrical part made up of or connected to the rotor in an electric generator, whereby by moving the two adjacent bodies connected to the movable links in which a rotor and a stator of an electric generator are respectively generated energy that is output by cable. The apparatus is assembled in a compact form for ship and water disposition and serves as a source of electricity during emergencies. The disadvantage of the above solution is that its effectiveness depends on directing the floating bodies in the direction of the waves, whereby obviously the best effect will be obtained in the case of perpendicular targeting.

Technical nature

It is an object of the invention to provide a system for extracting electric energy from tidal waves, sea currents and wind waves on the surface of water basins, the energy generated by the swinging of mass wheels with weights and the operation of the generator not to be connected with the operation of the generator. targeting its floating organs.

The task is solved by an offshore power generation system comprising energy generating means, an electric generator and a main electrical cable, characterized in that the energy generating means comprise at least one insulated housing housing at least three weight wheels with each gear wheel connected to a power cylinder with a non-return valve or to a hydraulic pump powered by a permanent oil tank and the insulated housings housed in the water basin. but either on the platform is anchored to the bottom of the water basin and provided with ballast, in which a tension cylinder or a hydraulic pump is connected to the pressure vessel and the hydraulic motor which drives the electric generator.

The high pressure tank, the hydraulic motor and the electric generator are housed in the insulated housing, with the main electrical cable connected to an electrical transformer located on a pontoon or ashore.

The high pressure tank, the hydraulic motor and the electric generator are placed on a pontoon, the main electrical cable being connected to an electrical transformer located on the pontoon, the connection being made between the hydraulic pump and the hydraulic motor by means of lead cables.

The housings are secured to the bottom of the water basin by means of anchors, to which anchor ropes are fitted, fitted with spring shock absorbers.

DETAILED DESCRIPTION OF THE INVENTION

Option 1 - stand alone buoy.

In a separate and insulated housing 1, three swing wheels 2 with weights 3 are mounted, which are connected to gearboxes 10 and are also connected to a hydraulic pump via gearboxes. In motion of the housing 1 as a result of the sea waves, the swing wheels 2 with weights 3 activate the hydraulic pump 4, which is fed by a constant oil tank 7, and in turn the hydraulic pump 4 supplies pressurized oil to a high pressure tank 6, driving a hydraulic motor 5, which rotates the generator 8. At the end of this cycle the oil is returned to the tank 7 for constant mass lo. The self-contained and insulated housing 1 is provided with ballast 9 and is secured to the bottom of the water basin by means of anchors 14, to which anchor ropes 13 are provided, provided with spring shock absorbers 15, and the electricity generated from the generator 8 is passed to transformer 16 , which was exported to pontoon 19. El. energy is brought to shore by a power cable 12.

Option 2 - several stand-alone buoy or gondola enclosures with a common generator.

Several self-contained housing 1 type buoy or gondola type (for example as shown in Fig. 3-6) are connected to a pontoon 19 on which a high pressure tank 6, a hydraulic motor 5, an electric generator 8 and a transformer are mounted. 16, the pumped oil from the hydraulic pumps 4 of each separate housing 1 is transported to a high pressure tank 6 to the hydraulic motor 5 by means of lead cables 11, and the electricity generated in the generator 8 is sent to a transformer 16, from where through the main electrical cable 12 is carried by 19 tons to shore.

Option 3 - a combination of gondola type float housings and buoyancy type float housings with common ones: a high pressure tank 6, a hydraulic motor 5, an electric generator 8, and an electrical transformer 16 that are suspended on a floating platform.

Gondola type 1 floats and buoyancy type 1 floats, which are provided at the bottom with ballast 9 and anchored to the bottom of the water basin by means of anchors 14, to

which have anchor ropes 13 fitted with spring shock absorbers 15, wherein four, eight or more flywheels 2 with weights 3 are mounted in the housing 1 of the gondola, and three flywheels 2 with weights are mounted in the housing 1 of the buoy. 3. The swing wheels 2 are connected to the hydro pump 4 by gearboxes 10, whereby the hydraulic pump 4 is fed by a constant oil tank 7 and pushed by the oil to a common high pressure tank 6, a hydraulic motor 5, a drive electric generator 8. The generated from the generator 8 the electricity is transferred to the electric transfo formers 16, which is on the shore or off the private pontoon 19.

Application (use) of the invention

From the movement of water waves, wind gusts and sea currents, the housing 1 swings, which in turn drives the gear wheels 2 with weights 3, which in turn drive the gearboxes 10. The gearboxes of the gearboxes 10 increase the torque of the pump 4 several times. which in turn creates the oil pressure that enters the high pressure tank 6. As soon as the required pressure is obtained, the oil moves to the hydraulic motor 5, which drives the required speed and power of the generator. a 8, which results in the generation of electricity that is output to the transformer via a main electrical cable 12.

The advantages of the invention are that in the construction and operation of the generator:

1. The environment is not polluted;

2. Part of the coastline shall not be taken away;

3. The equipment can be placed in places with different dynamics of waves and wind and can be moved without adversely affecting the environment;

4. There are no restrictions to assemble a multi-element power plant;

5. The generator uses not only the energy from the waves in the water basins, but also the energy from the wind;

6. The tides do not adversely affect the operation of the generator.
