CLAIMS

1. At least one power plant for generating electrical power from the waves which occur on the sea surface, wherein the subject matter power plant comprises at least one pump (4) which functions by using mineral oil for absorbing the hydro-mechanical power of waves, at least one hydro-motor (7) driven by said pump and where movement energy is obtained, and at least one alternator (8) driven by said hydro motor (7) and which transforms movement energy into electrical energy.

Description:
A WAVE POWER PLANT

TECHNICAL FIELD

The present invention relates to generation of electrical power by receiving the hydro mechanical power of waves, which occur on the sea surface, by means of pumps by using mineral oil, by storing of said hydro-mechanical power, by balancing the flow rate, which comes from the pumps, through the tank, and by turning the alternator by means of the drive of the hydro-motor.

PRIOR ART

In the present art, the power plants made in the wave energy subject do not exceed the capacity of 0.5 MW. Australia (Document No: 1 ), England University of Edinborough Wave Power Group, Scotland Islay island Limpet research team’s plant (Document No: 2), Japanese Marine Science and Technology Centre, Norwegian Wave Power Group and German Mannesmann-Rexroth and Denmark (Document No: 3 - 4) continue their researches about wave energy area. These researches are delimited by the studies of evaluating the hydro-mechanical energy of waves, which arrive at the shore and which leave the shore, at the structures fixed at the shore and rotating a turbine or rising of the waves, which arrive at the shore, by means of hydro-mechanical energy, and filling a reservoir fixed at the shore and obtaining electrical energy by means of a turbine through the height difference formed with respect to the sea level. However, the researches made with the partnership of the German Mannesmann Rexroth and Denmark are based on the lifting power of the waves which occur on the sea surface by means of fiber ropes connected to the sea base inside the sea.

These systems are not suitable for high-powered plants. Because in the systems realized at shores, very wide reservoir areas are required.

Since only shore is taken as a base, the amount of energy which can be generated cannot exceed a specific size. Therefore, it will be more suitable to view the event of receiving the unlimited hydro mechanical power of waves, existing on the sea for realizing wave power plant with the desired size, from another perspective.

As a result, because of all of the abovementioned problems, an improvement is required in the related technical field.

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a wave power plant, for eliminating the above mentioned disadvantages and for bringing new advantages to the related technical field.

The object of the present invention is to meet the energy requirement of our world by setting up clean and environment-friendly power plants which do not have any dirt and which have the desired size and by receiving the wave energy, which occurs naturally, by means of hydro-mechanical control mechanisms in a technological manner.

In order to realize the abovementioned object, the present invention has been designed to provide receiving of hydro-mechanical energy of waves which occur on the sea surface, to receive energy by means of mineral oil pumps connected to sensor tanks which are in number which is suitable for the amount of desired energy, to control said energy in the hydro-accumulator and to rotate the alternator by means of the drive of hydro-motor and to receive electrical energy; wherein the system is modular and thus, the system can be developed in big size and in small size as desired acccording to the requirement and according to the wave size.

BRIEF DESCRIPTION OF THE FIGURES

Figure 2 is the cross-section of the hydro-accumulator.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter wave power plant is explained with references to examples without forming any restrictive effect only in order to make the subject more understandable. The subject matter wave power plant comprises the following parts: Main steel construction, sensor tanks connected to this steel construction in a rotary manner, pumps, mineral oil, hoses, check valves, valves, throttle valves, pressure adjustment valves, pressure regulators, hydraulic potential energy accumulator, hydro-motors, alternator, voltage regulator, energy generation control panel, conductors.

In the wave power plant represented by Figure No: 1 , the sensor tanks, described by number 1 , are connected to the chassis, described by number 2, by means of the bearing, described by number 3, by their movements on the wave, and they transfer the energy, formed by wave movements, to the hydro-motor (7) by pumping mineral oil by means of pumps (4). The low pressure hydro-accummulator, shown by number 5 on the absorption line for the pumps, controls the required flow rate and pressure on the absorption line. The high pressure hydro accumulator, shown by number 6 on the press line, controls the pressure of the circuit by means of pressure adjustment regulators according to the energy requirement obtained from the alternator. At the same time, the required stock volume in the circuit is formed and the required flow rate and balance in the system is provided and the alternator, shown by number 8, is turned by means of the hydro-motor, shown by 7, and the desired energy is obtained. Thus, the hydro-mechanical energy of the waves is transformed into electrical energy, and the Wave Power Plant is implemented which does not have any other expense except the first cost and the maintenance expense.

The hydro-accumulator, represented by Figure No: 2, stores the pressured mineral oil, which is needed by the system, in the steel body shown by number 1 . The piston, shown by number 2, separates the mineral oil and the gas from each other. The check valve, shown by number 3, provides storage of the mineral oil with maximum pressure and in variable volume. The line, shown by number 4, feeds the hydro-motor.

Since this system comprises a system which can receive energy at each wavelength, it is designed according to the smallest wavelength and the desired electrical energy is obtained. There is no specific wave size for this system.

This system is excellent for clean environment and cheap energy, and it will provide incentive for realizing heating by means of electricity since it provides cheap energy in dense populated cities.

The connection of the wave power plants to the inter-connected circuit will provide the water reserves in the barrages to wait as energy stock. The cost of the energy, which will be generated by means of the wave power plant, is delimited with the first installation cost and maintenance costs and there is no other additional cost. Since the Wave Power Plant which does not have any polluter is completely environment-friendly, a clean nature will be reached by means of unlimited and clean energy.

The protection scope of the present invention is set forth in the annexed claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
