Abstract

The invention solves the problem of efficient and environmentally friendly production of electricity, which is solved by a multi-stage hydraulics, which allows the pumping of liquid in a closed system. The closure of the system solves the problem of the use of one and the same liquid or gas, therefore it is independent of the constant supply of natural sources of energy. A multistage hydraulics solution solves the problem of consuming a minimum amount of energy for the system itself, ie for its optimum utilization. The multi-stage hydraulics are designed by pushing the hydraulic cylinder in a larger hydraulic system through a small hydraulic system through the handle. A multistage hydraulic power plant with a compressor consists essentially of a tank (A), a lower hydraulic compressor station (B), an installation duct (C), a traveling element (D), an upper compressor station with a winding system (E) F), additional fluid reservoirs (G, H, I) and pumping station (J). Depending on the medium used in the reservoir (A), the multi-stage hydraulic power plant with the compressor can be implemented in two ways: either using liquid and gas or using two gases of different densities.

Description

The subject of the invention is a multi-stage hydraulic power station with a compressor, which can be placed anywhere on earth or in space, where there is an adequate force of gravity and a temperature that allows permanent liquid and gas stability in a closed system. A multi-stage hydraulic power plant with a compressor does not depend on natural energy sources, such as for example. coal, oil, gas, running water, uranium, wind, sun, and the like, so it can generate electricity anywhere, anytime, 24 hours a day, all days of the year. The gas and liquid used in the hydraulic compressor plant are in a closed system, so the same gases and the same liquid can be used throughout the life of the plant. A multi-stage hydraulic compressor power plant does not pollute the environment. It is built as a building partially or fully embedded in the ground or under water, e.g. to the bottom of the sea or lake.

The invention solves the problem of efficient and environmentally friendly electricity generation. Existing hydroelectric, thermal and nuclear power plants represent a major interference with and pollute the natural environment. Gas power plants depend on the proximity of large natural gas reserves. Wind farms depend on the presence of wind. Solar power plants are dependent on the sun and can only produce electricity during the day. Power plants that take advantage of the waves or tides of the sea can only be installed at appropriate locations in the sea. The technical problem of carrying out the invention is solved by multi-stage hydraulics, which allows the fluid to be pumped in a closed system. The closedness of the system solves the problem of using the same liquid or gas, so it is independent of the constant supply of natural energy sources. Multi-stage hydraulics solves the problem of consuming the minimum amount of energy for the system to function, ie for optimal efficiency. The multi-stage hydraulics are designed by pushing the hydraulic cylinder over the larger hydraulic system with the help of a smaller hydraulic system.

The principle of using buoyancy and gravity forces to generate electricity is already known and is proposed, for example, in patent applications. Patents SI 22556, SI 22815, SI 22762, US 2009/0293471, US 5944480, US 4718232, SI 20651, US2011 / 0162356, US 2006/0064975, and in an article on energy generation by buoyancy published at the International Technology Conference (2013) and Entrepreneurship (International Conference on Technology and Business

Management). The disadvantage of some of these solutions is that they work only theoretically and not actually, since the inventor has forgotten about certain factors, such as. friction, and in some others the power plant or engine itself consumes more energy than it produces. In addition, the present invention has certain advantages over the prior art according to the prior art. During the operation of a multi-stage hydraulic power plant, the compressor operates several generators simultaneously, which enables the production of more electricity.

It is closed type and can be placed anywhere. It can be placed close to power consumers, so it reduces the length of power lines. The multi-stage hydraulic system enables low power consumption for the operation of the power plant. During operation, it also utilizes the heat of generators to heat domestic water and living quarters. None of the above solutions uses the principle of gear-wheel operation and does not envisage the use of lighter gas, which enables a stronger buoyancy force.

* ·

Element A is a tall hollow structure with element C in the middle. The C element is constructed as a hollow pillar with evenly spaced Cl gears along the outer circumference. The toothed rails may be 2 or more and extend from the top to the ground of the C element. A gear wheel D3 is fitted to each gear bar with a built-in D17 generator. The D17 generator can also (second version) be mounted separately from the D3 gear wheel and connected to it via the clutch of the rotary adjuster. The D3 gears are mounted on the bearings on the bearings, to which ballast tanks Dl are also attached. The D3 gear wheels with the built-in Dl7 generator together with the Dl ballast tanks form a traveling element D.

Depending on the medium used in element A, a multi-stage hydraulic power plant with a compressor can be implemented in two ways:

Method of implementation I:

Using any suitable fluid with a specific density pi (preferably water) in element A and any suitable specific gas density p ₂ (preferably helium) in the ballast tanks D1 of the traveling element D. Where pi »p ₂ . The transmission of electricity is carried out through the cables El, which are simultaneously unwound and bent during movement of the traveling element D, so electrically conductive fluids in element A may also be used.

Method II:

With the corresponding gas of specific density P3 (preferably air) in element A and the corresponding gas of specific density p ₂ (preferably helium) in inflatable balloons of traveling element D. Where p3 »p ₂ . The transmission of electricity is done via the spring metal wheels D2 which roll on the C2 rails. Element A may also be implemented as an open system.

A multi-stage hydraulic power plant with a compressor utilizes gravity, the force of buoyancy on ballast tanks Dl, and torque as a product of the force and lever on the gear wheel D3 and the length of the path traveled by the traveling element D. Efficiency • · The generation of electricity depends on the length of the path perform the traveling element D, the size of the generator Dl7 and the difference in density between the fluid used in the element A and the gas in the traveling element D in embodiment I, respectively. from the difference in density between used gas 1 in element A and gas 2 in traveling element D in embodiment II.

In embodiment I, the hollow portion of element A is filled with fluid Al and the traveling element D has ballast tanks D1 properly constructed. When the traveling element D is in the lower end position, as shown in Figure 4, it is blocked by the hydraulic lock D4 shown in Figure 5. Automation via switches activates the hydraulic D5, which seals the connection between the ballast tanks Dl and the gas tank BI and at the same time activates D6 hydraulics, which seals the connection between ballast tanks D1 and hydraulic system B2. The automatics then opens the valves D7 and D8 via the hydraulics and activates hydraulic system B2 to pull the piston B4 to its initial position, thereby transferring fluid from the ballast tanks to the free-fall Div piston cylinder B3 and drawing gas from the BI gas tank. The gas is pressurized, further accelerating the process of draining fluid from the ballast tanks Dl. Liquid is driven by an additional generator with folding blades B5, which charges the B6 batteries, or, if they are already full, through the compressor B7, provides optimum pressure in the BI gas tank, or. Hydraulic system B2 provides optimum pressure for the hydraulic system to store energy for later use. When all the fluid is drained, the automatic valve closes the valves D7 and D8, releasing the sealing D5 and D6 and the hydraulic lock D4. At full throttle ballasts Dl, a buoyancy force is applied which causes the gears D3 to rotate and the travel of the traveling element D towards the top of the element A. The rotation of the gear wheels D3 causes the rotation of the Dl7 generators and the production of electricity. Electricity is transmitted through El cables, through the winding system E2 and the transformer station FI to the grid.

While traveling the traveling element D towards the top of element A, the automatic system starts hydraulic system B2 in the lower hydraulic compressor station B, which pushes the piston • ·

Β4 of piston cylinder B3 in the upper position, thus returning fluid from piston cylinder back to element A. During fluid flow from piston cylinder B3 to element A, generator B5 is not activated because it has folding blades in this direction of flow, as shown in Figure 6 In the case of high pressures, when fluid Al is used in element A, a multi-stage hydraulic system with lever is used, thus reducing the energy consumption to return the fluid to element A - Figure 6. Multi-stage hydraulics are designed so that the smaller hydraulic system B9 pushes the clamped lever. B8 on the larger hydraulic system B2. Hydraulic system B2 generates a pressure that pushes piston B4 of piston cylinder B3 which presses fluid Al back into element A.

At the appropriate distance in front of the upper end position of the traveling element D, the automatics initiates regenerative braking of the traveling element D with regenerative braking generators D10. They produce additional electricity and recharge the Dll batteries, or, if they are already fully charged, provide the hydraulic system with optimum pressure through the D12 hydraulic system, thus storing energy for later use. When the traveling element D reaches the upper end position, the automatic element locks the traveling element with the hydraulic lock D4. Then, the automation triggers the Dl3 hydraulics of sealing the connection between the Dl ballast tanks and the upper compressor tube E3. Now the automatics open the hydraulic valves D14, D9 and D7 and allow the fluid to flow freely inside the ballast tanks Dl of the traveling element D. The compressor E3 sucks the gas from the ballast tanks Dl, which speeds up the process of filling the ballast tanks Dl of the traveling element D with the fluid. When the ballast tank is full, the floating ball Dl 5 closes the fluid passage to the gas pipe system D16, which activates the closing of valves D14, D9, D7, release the hydraulic seal Dl3 between the ballast tanks Dl and the upper compressor hose E3, and release D4. The gravity force on the traveling element D with full ballast fluid reservoirs, causes the rotation of the gear wheels D3 and the rotation of the generators D17 and the production of electricity during the free fall of the traveling element D. At the appropriate distance from the lower end position of the traveling element D, the automatic triggers element D with D10 generators. When the traveling element D reaches the lower end position, the automatic locks the traveling element D with hydraulics D4.

D10 generators perform regenerative braking and control the speed of rotation of the D3 gear wheels - Dl7 generators and thereby control the electricity production. Hydraulic lock D4 locks the traveling member D in the lower and upper extremities and enables emergency locking. The communication between the control and control room F and the D10 braking generators and the D4 hydraulic interlock is via the communication cable El, which is bent and unwound together with the power transmission cable El via the winding system E2.

Dl ballast tanks may be made of metal or other suitable high pressure materials. The inside of the ballast tanks is surrounded by a Teflon glaze. The cross section of element A is of circular shape due to high pressures. If the system of element A is hermetically sealed, an expansion vessel E6 is provided in the upper part which allows the liquid Al to stretch. The heat pump E4 through the heat exchanger E5 cools the liquid Al in element A, which is heated by the generators D17. A4 heat pump heats Al fluid in case of very low temperatures at power plant startup. In the case of maintenance work, fluid Al is drained from element A into the additional reservoir of fluid I via flap A3. Elevator A2 is used to access element J - room with pump JI for pumping fluid from the additional fluid reservoir I into the additional fluid reservoir G and H via the fluid pumping pipe 12. The pump JI pumps the fluid from the suction basket II through the pipe 12 via the flow diversion valve fluid 13 to the auxiliary reservoir of fluid G and H. After the maintenance work in element A is completed, fluid Al is re-flowed to element A, first from the additional reservoir H through the flow hatch HI and then from the additional reservoir G via the flap Gl.

In the case of embodiment II, using two gases of different specific densities (p ₃ > p ₂ ), the transmission of electricity is carried out via the spring metal wheels D2 which roll on the rails C2. The operation procedure is the same as in Mode I, except that balloons are used instead of ballast tanks and quick-release couplings instead of hydraulic connection valves D9, D8, D7, D14. In this embodiment, we do not need the elements G, H, I and J and their components.

In case of a need for uninterrupted supply of electricity, two identical power plants shall be installed such that when the traveling element D of one is stationary, the traveling element D of the other travels.
