Description

The utility model relates to hydroelectric construction. Intended for the operation of damless water resources. A vivid example of damless hydropower is the Kuril ridge through which, in innumerable great quantities (tens of Guat of easily extracted electricity), carries the Pacific Ocean to the northern part of the Sea of Okhotsk with ebb and flow. Hydro generators are divided into low-speed rotating up to 100 rpm, high-speed more than 100 rpm. In the proposed utility model, the generator rotates up to 10,000 (ten thousand) rpm. Two radial-axial hydraulic turbines rotate one generator.

Hydraulic units are known: USSR author's certificate No. 314921 of 11/11/1970, author's certificate No. SU 1227827 of 10/22/1984. Their disadvantages are low-speed because of arch-bulkiness, high labor and material costs. They require the construction of dams and reservoirs, are not able to process damless hydro resources, and repeatedly limit the capacity of hydraulic units according to the generator. Judge for yourself the largest hydraulic unit with a capacity of 640 MW has a diameter of 20 m. A generator weighing 1,680 tons rotates it with a radial-axial hydraulic turbine with a diameter of only 6 (six) meters. The technical task of the utility model is the efficient operation of damless water resources.

To solve the technical problem, in addition to the features similar by analogs: the presence of a turbine hall, turbine wheel, hydraulic generator shaft, hydraulic generator shaft, bearing base, bearing assembly, water shutter, pressure pipe, suction pipe, there are new distinctive features, the foundation of a hydraulic pump, the base of a hydraulic pump , pump casing, pump rotor, pump shaft, turbine wheel vanes reverse, Reducer-bearing differential speed converter.

The utility model proposed for patenting differs from its analogues in that the pressure of water on the hydraulic turbines does not come from the reservoir, but from the hydraulic turbine pump that processes low-pressure, natural, damless energy into high-pressure supplying it to radial-axis turbines. Damless hydraulic units are built 5 (five) times faster, with 3 times less investment (after all, no dams and reservoirs need to be built). At the hydropower plant under construction, no more than 30% of investments will be spent. The main capital will be mastered at the plants building damless

hydraulic units. Here, the hydraulic unit is completely and completely constructed, debugged, run-in and, after minor dismantling, is towed by waterways to the hydropower station under construction. Where it is installed over an already constructed foundation, it is flooded, completely fixed to the foundation and brought to a working state.

A superfast, damless twin-engine hydraulic unit is schematically depicted in the drawing. It contains 1 machine room, 2 turbine wheel, 3 hydro turbine shaft, 4 hydro generator, 5 hydro generator shaft, 6 bearing unit base, 7 bearing unit, 8 water lock, 9 discharge conduit, 10 suction pipe, 11 foundation of the turbine pump, 12 base of the turbine turbine pump, 13 pump casing, 14 pump rotor, 15 pump shaft, 16 reverse turbine wheel blades, 17 "Reducer-bearing" differential speed transducer.

A machine room was built on the shore of a reservoir with damless hydraulic resources. 1 a hydraulic generator was mounted in it 4, a kind of turbine generator of the KTA-1200-K brand, the elongated shaft ends 5 of which rotate at differential speeds "Bearing Reducer" 17. They also rotate along one of the shaft ends 3 hydraulic turbines other parts of the shafts of 3 hydraulic turbines are mounted in the bearing assemblies 7. Two turbines operate on one generator, and thanks to the reducer-bearing dps 17, the rotational speed of the shaft 3 of the hydraulic turbine increases ten orders of magnitude and can reach 10,000 (ten thousand) rpm. The hydrogenerator has a capacity of 1200-1300 Mwat; its weight does not exceed 140 (one hundred forty) tons. With an increase in the rotation speed of the hydrogenerator, as well as a decrease in its power, for example, up to 700 MW. its weight can be noticeably less than a hundred tons.

At the bottom of a pond with damless hydraulic resources, there is 11 foundation of a turbine pump; on it are 12 bases of a turbine pump, 13 pump housing, 14 pump rotor, 15 pump shaft, 16 reverse turbine wheel blades. 3 The shaft of the hydraulic turbine pump is mounted in the gearbox of the “Bearing-bearing” 17 which allow it to rotate at a speed much faster than the 3 hydraulic turbine shafts ie up to 10000 rpm. Hydroturbines rotate slowly of the order of 100 rpm, the rotor 14 of the pump is tens of thousands of rpm. The rapidly rotating rotor 14 of the hydraulic turbine pump creates a high pressure in the 9 pressure pipe which is fed to the radial-axis turbine of the hydraulic unit. For each hydraulic turbine of a hydraulic unit several hydraulic turbine pumps can operate. A flow of about 4 atm acts on the turbine wheel of a pump mounted at a depth of a reservoir having damless hydro resources. the same pressure is present at the suction of the hydroturbine

pump if it increases the pressure only 5 times, then the pressure will be applied to the turbine unit 20 atm, which is equivalent to the pressure of the water of a 200 meter dam.

Statics: Reverse 16 turbine wheel blades set the blades (not shown in the drawing) parallel to the water flow. The latter does not interact with the turbine wheel by the pump shaft 15, the rotor 14 of the hydraulic turbine pump does not rotate, there is no pressure in the pressure pipe 9, the hydraulic unit does not give electric current.

The superfast, damless twin-engine hydraulic unit works like this. The reverse of 16 blades (not shown in the drawing) of the turbine wheel of the turbine pump installed them at an angle to the flow of water, they interact, the turbine wheel, shaft 15, rotor 14 of the turbine pump rotate creating energy pressure in the pressure duct 9 rotates the radial-axial turbine of the shaft 3 dps “Reducer-bearing”, increasing the rotation speed of the generator shaft by orders of magnitude up to 1000 rpm. The generator spinning generates an electric current.

The superfast two-engine hydraulic unit is stopped by installing reverse 16 blades (not shown in the drawing) parallel to the water flow. The turbine wheel, shaft 15, the rotor 14 of the turbine pump does not rotate, there is no water pressure in the pressure conduit 9, the hydrogenerator does not give electric current.

Owing to the differential reducer-bearing speed converter 17 in which the shaft 3 of the radial-axial hydraulic turbine rotates, the generator 4 rotates at a speed of 3000 rpm or more similar to KTA-1200-K. For the same reasons, the shaft 15 of the rotor of the turbine pump rotates orders of magnitude faster than the shaft of the turbine. The energy of free-flowing waters of large high-water rivers also refers to free hydro resources. There is a project of Nizhne - Lenskaya hydroelectric power station with a capacity of 20 Gwat. This indicates the huge reserves of damless hydro resources of the Siberian rivers. Processing it will provide these places with very cheap electricity (costing less than 10 kopecks per 1 kW / hour. In some areas of these places they pay more than 20 rubles per 1 kW / hour.)

The differential gearbox bearing “Reducer-Bearing” is described excellently in the journal “Expert” for 2002 on pages 52-55 No. 34 continued in No. 37.

The enormous efficiency of the utility model is provided by 2 stages of “Reducer-Bearings” differential speed converters increasing the rotation speed of the respective shafts by 2-2.5 orders of magnitude each.
