Definitions
- SUBSTANCE group of inventions relates to the hydropower industry and is intended for generating electricity from the energy of sea waves.
- Hydropower namely: hydrowave energy is a kind of non-traditional energy, which is based on the use of the energy of sea waves by converting the kinetic energy of the waves into hydraulic energy of hydraulically driven mechanisms for use in electric generators to generate electricity.
- the energy of sea waves is a renewable source of energy, it is virtually inexhaustible, environmentally friendly, and contributes to the preservation of the environment.
- wave energy there are various ways to generate wave energy, the main, more commonly used, is the use of the movement of a large wave up and down to create a flow of air or water and direct its pressure to drive a turbine or floating buoy to generate electricity. Also, torque gyroscopes are often used in methods for generating wave energy.
- the process of generating electricity consists of the following steps: transferring the force from the movement of sea waves to the rotation shaft of the rotary gyroscope due to the pressure of the lever and transferring the rotational movement from the gyroscope shaft to the generator armature shaft.
- the process of generating electricity occurs as follows: the rotation of the generator armature shaft, which generates electricity, is created by the drive wheel of the rotor shaft, which is rotated by two drive wheels of the gyroscope.
- the rotation of the drive wheel of the rotary gyroscope is created due to the pressure of the lever, which transmits the force from the sea waves to the rotation shaft of the rotary gyroscope (see, for example, international application with publication number DE 102009032930, IPC F03B 13/18 dated 14.07.2009).
- a method of using the energy of sea waves which includes the perception of the energy of sea waves with the help of buoyancy objects and the transfer of this energy to the actuator using vertical rods fixed on the buoyancy objects, and a gear train, where the buoyancy objects that perceive the wave energy are placed in the guide shafts, which are openwork, they transfer energy to the actuator using gear racks, which are installed in box-shaped rods with the ability to move in them, and ratchet gears, which are installed on the main shaft, while the rods are parallel to the guide shafts, toothed racks are inserted engage with the ratchet gears when the buoyancy objects move up and disengage them when the buoyancy objects move down, accumulating mechanical energy on the line of the main shaft, which is placed horizontally with a flywheel and transmitted through a gearbox to an electric generator, (see, for example, m international application with publication number RU02221933 , IPC F03B 13/18 dated February 14, 2002).- [4]
- this method is relatively inefficient, because it requires sophisticated equipment. By intermittent spinning of the flywheel and acceleration of the main shaft of the actuator, it is difficult to regulate the uniform supply of electricity to the consumer. Therefore, this method has a relatively insufficient reliability in operation.
- a material that accumulates pressure in a reservoir of variable capacity from liquid under high pressure, with its further use for springs, tires, shock-absorbing materials, seismic isolation materials, and so on.
- the residual energy produced by the generator is used to concentrate sea water and obtain mineral substances from it by electrolytic synthesis, (see, for example, international application with publication number JP203185582, IPC F03B 13/22 dated 19.09.2013) - [5]
- this method is relatively ineffective, since it requires complex equipment in accordance with the tasks that it solves, mainly for obtaining minerals from sea water by converting the energy of sea waves into the electricity needed to perform the electrolytic synthesis.
- a device for a wave power plant for generating electricity from the energy of sea waves, which contains a screw energy converter made in the form of a bladed screw connected by a coupling to the shaft and through a step-up gearbox with a generator, a casing, a water craft and additionally contains a rod that is rigidly fixed to the watercraft; a rod pivotally connected to the rod; a rack in which a shaft is installed in bearings; a bracket that is attached to the stem on one side and to the rack on the other; a water flow concentrator with guide vanes, which is connected to the rack using holders; moreover, the blades of the blade propeller are flexible and elastic, and are rigidly fixed on one side on the spoke axles, (see, for example, the patent of Ukraine for utility model No. 59023, IPC F03B 13/14, F03B 13/16, F03B 13/20, F03B 13/22, dated 26.04.201 1) - [6]
- the known installation device is relatively ineffective. It requires complex additional equipment such as a water flow concentrator, and a vane screw energy converter at high waves has a relatively insufficient reliability in operation.
- a device is known as a marine wave power plant, which contains a central pontoon, along the outer perimeter of which the main pontoons are mounted, on which high-pressure cylinders (HPC) and a hydraulic turbine are located, along the outer perimeter of the central pontoon several main pontoons are connected by horizontal axial hinges, on which high pressure cylinders were mounted, connected from one end to the main pontoon by a horizontal axial hinge parallel to the axial hinge between the central and main pontoons, a piston is placed in the middle of each cylinder in the form of a three-dimensional frame, in which a rotary-blade hydroturbine (PLGT) is mounted with a blade rotation angle from - (D to + ⁇ , a hollow rod, at one end attached to a piston made in the form of a spatial frame, at the other end connected to the platform, which is located on horizontal axial hinge, parallel to the axial hinge of the HPC, which connects it to the main pontoon, the PLGT and the electric generator
- the known installation device is relatively ineffective. To reduce the gust of equipment, the working fluid from the high-pressure cylinders and the tank is directly fed to the variable-blade hydraulic turbine connected to the electric generator.
- the equipment of the known device is relatively complex and has a relatively insufficient reliability in operation.
- a marine wave power plant in which six pairs of pontoons are mounted around the central pontoon along its outer perimeter, the closest one to the central one is the main one, and the far one is the auxiliary pontoons, the central, main and auxiliary pontoons are connected to each other in series by horizontal axial hinges.
- the mentioned well-known power plant installation consists of a central pontoon, in the upper part of which there is an engine room with a softening high-pressure tank, a hydraulic turbine and an electric generator, a hold for the waste liquid is provided under the engine room.
- main pontoons are installed in pairs and auxiliary pontoons interconnected by horizontal axial hinges.
- the main pontoons are equipped with high pressure cylinders (HPC) with a system of inlet and outlet valves, flexible high pressure piping and vacuum piping.
- HPC high pressure cylinders
- the piston rods of the HPC are pivotally connected to the body of the central pontoon and the auxiliary pontoon.
- the installation is anchored with at least two anchors.
- the proposed installation foresees twice as many modules of similar size, and all the energy received from the waves is utilized into electrical energy in one turbine hall, which is located on the central pontoon.
- the installation is placed on at least two anchors to prevent the rotation of the central pontoon around its axis, which will allow the transmission of the received electricity through an underwater power cable (see, for example, the patent of Ukraine for the invention No. dated August 25, 2009). - [8]
- this marine wave power plant is relatively inefficient, since there is a possibility of rotation of the central pontoons around its axis, which is inconvenient during its operation and therefore has a relatively insufficient reliability in operation.
- Known marine power station which contains a floating platform made in the form of a float frame, for example, in the form of a hollow metal structure to ensure its buoyancy, with at least one mounting module, which contains an electric generator and a screw energy converter, made in the form of a bladed propeller with a shaft , which is located in the zone of the underwater flow and is connected to the shaft of the electric generator through a transmission mechanism and is additionally provided with an underwater platform, which is connected by at least one rigid armature to the floating platform, and the propeller of each module is placed on a support, the lower part of which is installed in the groove, which is made on the underwater platform, the upper part is attached to the floating platform by means of removable fasteners, and the underwater platform is provided with at least four chains for fastening to the bottom, and the mounting modules are electrically connected to each other.
- the overall dimensions of the floating platform are such as to ensure the unsinkability of the entire structure. Also, the overall dimensions of the floating platform depend on the number of mounting modules designed to convert the energy of the water flow into electricity. Accordingly, if it is necessary to use power plants of greater capacity (ie, with a large number of mounting (energy) modules), then the area of the floating platform should be larger. If necessary, the number of mounting modules can be changed by their mechanical attachment or separation. (See, for example, a patent of Ukraine for a utility model No. 93412, IPC F03B 13/18, F03B 13/22, dated 09/25/2014). - [nine]
- the well-known offshore power station is relatively inefficient, since its platforms, both the lower underwater and the upper floating ones, are movable, which makes it insufficiently convenient for its operation and makes it impossible to use the station as an island.

- the movement of the float through the rod, chain and sprockets is transmitted to the rod of the hydraulic cylinder, which performs a vertical up and down movement.
- the lower and upper cylinders of the hydraulic pump 9 the body of which is fixedly fixed by fastening 16 on the frame 15, respectively suck and pump water to the high-pressure accumulator 10. With each movement of the float 1, namely: at 17
- FIXED SHEET moving up with the help of a low pressure hose 13, water is sucked into the lower cylinder of the hydraulic pump 9 from the drain tank 12 and at the same time, using a high pressure hose 14, fluid is supplied from the upper cylinder of the hydraulic pump 9 to the accumulator 10.
- the liquid is sent to the hydro generator 1 1 to generate electricity, while the waste fluid from the hydrogenerator 1 1 is sent to the drain tank 12 and then again to the hydraulic pump 9, ensuring the continuity of the power generation process.
- a valve opens, through which the liquid under pressure in a few seconds leads to the operation of the hydrogenerator, while the main energy parameters are frequency, current strength and voltage are constant and and given.
- the claimed device the constructive solution of which makes it possible to obtain wave energy, convert it into the energy of a liquid under high pressure, accumulate it, store it and use it, turning it into electricity, at any necessary time, for any need, ensures efficient generation of electricity from the energy of sea waves that solves the problem set before him.
- Figure 3 shows the flow diagram of the placement of floats sections of the marine power station-island (MES-island) in accordance with the vertical movement of the wave up and down.
- MES-island marine power station-island
- Fig. 4 shows a view of a fragment of the engine room from sections of a marine power station-island (MES-island), made from the combined structures of sections and platforms.
- MES-island marine power station-island
- a marine power station is a man-made island (MES-island), which consists of many interconnected sections (devices for generating electricity from the energy of sea waves). Each section consists of four vertical tube-shaped supports, horizontal tubes welded to the supports in several places, at least two platforms, forming the frame of the engine room of the MES-island. On the platforms, energy storage devices, drain tanks, generators, a working mechanism that transmits movement through a rod and a chain mechanism to a hydraulic or pneumatic pump are installed. Some sections have aisles for attending staff. Other sections are equipped only with a float and devices for obtaining technical water from sea water without the use of electricity, that is, water obtained directly through a hydraulic pump.
- Offshore power islands can be of different sizes, their pumps and accumulators can operate both on compressed air and on a "compressed” liquid and use both pneumatic accumulators and hydraulic accumulators. So, bringing the pressure in them to a predetermined values, turn on the generator by opening the valve and receive electricity in a convenient way.
- a frame of the MES-island is made, on which all the necessary equipment is installed, the performance of the station is tested, and then the MES-island is transported to the installation site, attached to the seabed, cables are laid on land and the equipment is started.
- the sea wave shakes up and down the float chamber, which is one-third submerged in sea water.
- the movement of the float is strictly vertical thanks to special hydraulic guides.
- the movements that pump the float “up and down” are transmitted to a hydraulic pump (compressor), which pumps liquid (or air) into the accumulator (high pressure vessel).
- the hydroelectric generator or pneumogenerator
- the hydroelectric generator due to the flow of liquid (air) under pressure to it, generates electrical energy of specified parameters (frequency, voltage, current strength), which is transmitted to the "mainland” (land) to the general electrical network or to a specific consumer.
- the accumulated pressure energy in the form of compressed air or liquid
- a float which has an area of 0.78 m 2 in horizontal section (for a section with dimensions in section 1x1 m) up to 80 m 2 (for section with dimensions in section 9x9 m).
- a section with a float area of 0.78 m 2 generates electricity of 4.5 kW/h
- a section with a float area of 80 m 2 generates electricity of 2400 kW/h.
- a valve opens, through which the liquid under pressure brings the hydrogenerator to work in a few seconds, while the main energy parameters are: frequency , current and voltage are constant and given.
- a marine power station-island (MES-island) is installed in the sea (ocean), where the depth is from 12 m to 30 m and where the average annual wave (up and down) is from 1 m to 14 m. From one square meter of the sea (by area bottom of the float), if you use air as an energy storage device, it is possible to receive an average of 6-8 kW / h of electricity when using a pneumatic generator (or 120-150 kW / h from one section) and 20 - 30 kW / h of electricity from 1 m 2 (or 400 - 600 kW / h from one section) when using hydrogenerators with a float area of 19.6 - 22.9 m 2 .
- each section of the MES is provided with several generators (pneumatic or hydro), which can be both quickly (in a few seconds) put into operation and quickly (in a few seconds) stopped.
- the system is controlled by an industrial computer.
- new generators are automatically connected, and when the voltage in the network increases, the "extra” (at the moment) generators are automatically turned off.
- competing energy systems no the "extra” electricity at a given moment goes to the ground.
- the energy system of the MES-island cannot endlessly accumulate energy in batteries (pneumatic or hydro). Therefore, excess (“surplus”) energy is directed to the operation of electric hydraulic pumps installed directly at the station to obtain process water.
- the MES-island energy system makes it possible to quickly start the process of turning on and off the power generation and transmission system due to the lack of the need for stabilizers and limiters when transferring high-pressure fluid movement to the electric generator.
- offshore power stations-islands are created mainly for two “products”: electricity and water.
- Industrial water at the station can also be obtained by another method:
- the mechanical hydraulic pump will direct the sea water under pressure to the sea water desalination system. Therefore, some sections of the MES-island are performed without generators and batteries, but with large water tanks. Due to the fact that there will be a lot of technical water on the MES-island, somewhere around 5-7 thousand m 3 per hour or more, some sections will be "empty", that is, not equipped with floats, but only water tanks .
- the claimed method, device and marine energy system-island for generating electricity from the energy of sea waves the constructive solution of which allows you to get wave energy, turn it into liquid (or gas) energy under high pressure, accumulate it, save it, turn it into electric and use at any necessary time for further transmission to the consumer and use the island for utilitarian purposes, provide efficient generation of electricity from the energy of sea waves, thereby solving their task.
