Pumped storage power plant for the generation of electricity

Abstract

The pumped storage power plant continuously generates an excess of energy (current) during operation, the level of the excess being dependent on the size of the plant. The mode of operation is simple and efficient. During operation, the pumped storage power plant consumes only a very small proportion of the energy / current that it produces, that is to say consumes less energy. Photovoltaic elements, which allow the start-up of the plant, fails or lead none of the energy yield, are described in the request.

Description

Name: Pumped storage power plant for generating electrical energy Description

[0001] The system requires a tower with several floors. Depending on the required * The towers are constructed according to the size and number of systems. According to claim 1, the tower consists of six floors. Each floor has openings to the upper and lower floors. The ground floor and the top floor contain the storage and inlet basins. The other floors ► The systems are located. The conveyor blades and conveyor chains are installed vertically in the openings on the rotor shafts: The water is fed from the upper reservoir or inlet basin through supply lines into the uppermost conveyor blade. The weight of the filled conveyor blades creates a pulling force, which sets the impellers in rotation. The impellers rotate the impeller shafts or ' Rotor shafts. The impeller shafts are coupled to transmission gears. They generate enormous revolutions. The transmission gears are coupled to generators and generate electricity. The electricity is then fed directly into the power grid. At the bottom of the tower is the storage basin, or lower basin, which collects the runoff water. The collected water is pumped back to the upper basin. Photovoltaic systems will be installed on the tower's exterior. They will generate electricity for the pumped-storage power plant, water pumps, and energy storage batteries. Once the plant is operational, it can also be operated autonomously using a fraction of the electricity it generates itself, and no longer requires an external power supply (e.g., via the solar panels on the outer shell). The entire system is operated by a system control system. This controls, monitors, and switches on the pumped-storage power plant and ensures that any excess electricity is fed into the grid. The plant's own electricity consumption represents only a fraction of the total amount of electricity produced. State of the art in renewable energy

[0002] Most pumped-storage power plants are unique to nature and operate on a single site. They require enormous amounts of water and land, which aren't available everywhere. This is not the case with this invention. It can be a good solution for expanding renewable energy generation. It can also be installed on large cargo ships and cruise ships to at least help reduce fuel consumption or even replace it entirely.

[0000] The pumped storage power plant can be expanded in the drive and transmission area if necessary. If powerful rotation of the transmission shaft is required, several impellers are connected to each other with cardan shafts and then to the gearboxes and generators. In Figure 5, for example, the system is arranged with nine impellers on the rotor shafts of the system platforms.

[0004] Each gearbox is preferably designed with multiple stages to achieve high speeds per minute, enabling the use of lighter and heavier generators. 1 REPLACEMENT SHEET (RULE 26) The gear ratio of the transmission can be set as required. The gear stages of the transmission can also be expanded if necessary, provided the load capacity of the individual components allows it.

[0005] To facilitate installation and repair work, an extension of the rotor shaft is provided on both sides of all impellers and can also be used for the extension of the system.

[0006] The extension of the rotor shaft 4 first passes through the braking system 28 then the first bearing block ► 12 of the transmission gear 50, where bearing block 12 is also the gear frame, then the shaft gear 11 and ends in the second bearing block 14 of the gear.

[0007] The first gear stage comprises the rotor shaft 4 as the first gear shaft, which is mounted in a first bearing block 12 and a second bearing block 14. The two bearing blocks are fixedly connected to the platform 40. The rotor shaft 4 therefore passes through the first bearing block 12 and ends in the second bearing block 14. At a distance from the first gear shaft or rotor shaft 4, a second gear shaft 6 is mounted in the two bearing blocks 12 and 14. This second gear shaft 6 begins in the first bearing block 12 and passes through the second bearing block 14 and ends in the third bearing block 16. Between the two bearing blocks 12 and 14, a shaft gear 11 is arranged on the first gear shaft 4 and a second shaft gear 13 is arranged on the second gear shaft 6. The two shaft gears 11 and 13 are mechanically coupled to one another.

[0008] The second gear stage comprises a third shaft gear 15 mounted on the second gear shaft 6 and a fourth shaft gear 17 mounted on the third gear shaft 8. The two shaft gears 15 and 17 are mechanically coupled to each other.

[0009] The third gear stage comprises a third gear shaft 8, which terminates in the bearing block 18 and extends through the third bearing block 16 with a protruding end 22. A fifth shaft gear 19 is arranged on the third gear shaft 8 between the two bearing blocks 16 and 18. A sixth shaft gear 21 is arranged on the fourth gear shaft 10. The two shaft gears 19 and 21 are mechanically coupled to each other.

[0010] The fourth gear stage comprises the fourth gear shaft 10, which ends in the bearing block 20, which also serves as the gear frame, and extends with a protruding end 24 through the fourth bearing block 18. A seventh shaft gear 23 is arranged on the gear shaft 10 between the two bearing blocks 18 and 20. A fifth gear shaft 26 is mounted in the bearing block 20 at a distance from the fourth gear shaft. The eighth shaft gear 25 is arranged on the protruding end 44 of the gear shaft 26, between bearing blocks 18 and 20. The gear shaft 26 passes through the bearing block 20 and, in the outer area, the bearing block 27.

[0011] After passing through the bearing block 27, the drive shaft 26 is provided with an extension. This extension is then coupled to the generator 29.

[0012] The endless conveyor chains and endless roller or bolt chains are tensioned with chain tensioners.

[0013] The design of the other gearboxes is identical. 0014] The conveyor blades are mounted on the endless conveyor chain, shown in Figure 1, for example, with 54 conveyor blades. Each conveyor blade has a capacity of approximately 100 liters of water. 2 REPLACEMENT SHEET (RULE 26) On the filling side, 24 of these are filled with 100 liters of water. A total of 2.4 tons of weight pulls the conveyor chain downwards, generating the rotation of the impellers, which are coupled to the generators via transmission gears. A tensile force of approximately 23,540 Newtons acts on the impellers or rotors. With each expansion of the drive area by one impeller on the system platforms A and D, the tensile force increases by approximately 11,770 Newtons. Figure 7 shows a combination of nine impellers arranged in the transmission area, achieving a tensile force of approximately 105,950 Newtons. This allows large generators to be operated.

[0015] The endless conveyor chains, the multiple sprockets, the impellers or rotors, the transmission shaft, the shaft gears, the cardan shafts, and the bearing blocks are made of hard, rust-proof materials such as stainless steel. The conveyor blades are made of lightweight yet robust, rust-proof and hard materials.

[0016] The drive area is wet and is covered with a protective device to protect the transmission area.

[0017] It shows: Fig. 1 a schematic representation of the system Fig. 2 is a schematic representation of the system without the tower. Fig. 3 shows a schematic detailed view of the upper plant platform A. Fig. 4 a schematic detailed view of a transmission gear, top view. Fig. 5 shows a schematic detailed view of the plant extension on plant platform A. Fig. 6 shows a schematic detailed view of the upper or inlet basins.

[0018] Fig. 1 shows a schematic representation of a first embodiment of the invention with a tower 1 comprising an upper end or tower roof 2 and a lower end or tower base 3. Several PV systems are shown at the top of the tower, which can be extended to the bottom of the tower to harvest more solar energy. Labels have been added to clarify the power storage batteries 35 and system control system 32. The tower offers ample space for the storage batteries and system control system.

[0019] The pumped storage power plant is a smaller version consisting of four plant platforms and two inlet and storage basins. The number of turbine platforms and the drive range can be increased. The drive range is extended with cardan shafts. This creates enormous pulling and torque, allowing the use of large generators.
