Description

The utility model relates to hydroelectric engineering. Intended for the operation of damless water resources. A striking example of damless hydroresources is the ebb and flow energy coming from the Pacific Ocean through the Kuril ridge to the northern part of the Sea of Okhotsk. Bearing an incalculably large amount (tens of Gwat) of easily recoverable hydropower. The northern rivers carry even more damless energy. Nizhne Lenskaya hydroelectric station (project) has a capacity of 20 (twenty) Gwat. confirmation of this. Known hydraulic units avt.sv. USSR No. SU 1227827 dated 10/22/1984, auth. USSR No. 314921 dated 11/11/1970. Their shortcomings are slow-moving because they are arch-cumbersome, high labor intensive, require the creation of dams and reservoirs, are unable to process damless hydraulic resources, and repeatedly limit the capacity of the hydraulic unit according to the generator. Judge you, the largest hydrogenerator in Russia, with a capacity of 640 mVat, has a diameter of 20 m, weighs 1,680 tons, it is rotated by a radial-axis hydraulic turbine with a diameter of only 6 (six) m.

The utility model presented for patenting does not have these disadvantages. It is intended for the operation of damless hydro resources.

To solve the technical problem, in addition to similar features with an analogue of a turbine wheel, a shaft of a turbine turbine, a capsule of a hydrogenerator, there are new distinctive features of a high-speed hydrogenerator, reverse of the blades of a turbine wheel differential speed reducer “Bearing-bearing”. The drawing schematically shows the right side of the high-speed damless multi-turbine hydroelectric unit. The left mirror image of the hydraulic unit remained behind the dashed line (figure 2).

The high-speed damless multi-turbine wheeled hydraulic unit contains.! foundation foundation of the hydraulic unit, 2 hydraulic unit bases, 3 turbine wheel, 4 hydraulic turbine shaft, 5 hydraulic generator capsule, 6 high-speed hydraulic generator, 7 hydraulic turbine blade reverse, 8 communicating tunnel, 9 bearing assembly, 10 high-speed hydraulic generator rotor shaft, 11 “Reducer- bearing".

A foundation 1 was built at the bottom of a reservoir with damless hydro resources, a base 2 of a hydraulic unit was mounted on it, a capsule 5, a high-speed hydraulic unit 6 was mounted in its central part, an elongated shaft 10 of the hydraulic generator was mounted in the village with “Reducer-bearing” 11. Shafts of 4 hydraulic turbines and the right and left hydraulic turbines in the village with “Reducer-bearing” 11 and in the bearing assemblies 9. Two turbine wheels are mounted on each shaft 4 of the turbine turbine 3. Therefore, the multi-turbine hydraulic unit has at least 4 turbine wheels 3 The cavity of the capsule 5 of the hydrogenerator is connected with the shore by a communicating tunnel 8 and power cables are laid in it , staff moves along it, the capsule is being ventilated. The reverse of the 7 blades (not shown in the drawing) of the turbine wheels 3 set them parallel to the flow of water. They do not interact with each other because the turbine wheel 3, the turbine shaft 4, the shaft 10 of the hydrogenerator are stopped, the hydrogenerator 6 does not create an electric current voltage.

The high-speed damless multi-turbine hydraulic unit works like this. The reverse of the 7 blades of the turbine wheels 3 mounted them at an angle to the flow of water. Due to the interaction of the blades (not shown in the drawing) and the flow of water, the turbine wheel 3, the shaft

Hydroturbine rotating shaft 4. Torque through d.p. with "Reducer-bearing" is transmitted to the shaft 10 of the high-speed hydrogenerator. Moreover, it is not only transmitted but increases the speed by a hundred or more times. The generator rotates up to 10,000 (ten thousand) rpm, creates an electric current voltage.

The hydraulic unit is stopped by installing the reverse of the 7 blades of the turbine wheel in a position parallel to the flow of water, the turbine wheel 3, the turbine shaft 4, the hydro generator shaft 10 are stopped, the generator does not generate an electric current voltage. A high-speed hydrogenerator can serve as a similarity to the KTA-1200-K brand turbogenerator rotating at a speed of 3000 rpm. It is two times more powerful than its counterpart and twelve times lighter - it weighs one hundred and forty tons. A high-speed damless multi-turbine hydraulic unit is constructed 5 (five) times faster and 5 times cheaper (no need to build a dam and a reservoir) In addition, no more than 30% of investments are mastered directly on the construction of a hydroelectric power station. The rest of the capital is mastered at the plants producing these hydraulic units. There it is assembled, debugged, run-in and, after a small dismantling, is towed by waterways to the hydropower station under construction. Where it is installed over an already constructed foundation, it is flooded and is wholly attached to the foundation and brought to a working state. The cost of electricity of a multi-turbine hydraulic unit is only a few cents per 1 quatt / hour. With an increase in the speed of rotation of the hydrogenerator to 6000 rpm and a decrease in capacity to 600 MW, the weight of the hydrogenerator will decrease noticeably less than a hundred tons.

To the existing recorded water resources, the unaccounted damless hydro resources should be added. Damless water resources are mainly located in the north and northeast of the country in some areas. 1 quatt of electricity costs more than 20 rubles.

The utility model “High-speed damless multi-turbine hydraulic unit” is distinguished by the fact that it works on damless hydraulic resources. It has a huge unit capacity of up to 1200-1500 Mwat, a modest size, the diameter of the generator is 4.2 (four) m. It weighs one hundred and forty tons. It is built five times faster and 5 times cheaper (no need to build a dam and reservoir). The cost of 1 Quatt / hour of electricity costs a few cents. Able to provide the north of the country with cheap electricity.

Differential speed transducer "Reducer-bearing" patent No.RU 2179272 C1 F16H 25/06 21 02.2002 excellently described in the journal "Expert" for 2002 in No. 34 p.52-55, continued No. 37. The patent is very hard to read.
