(57) Abstract:The unit is designed to convert the energy of water flow in electric and can be used for power supply. The unit contains two turbines and rotating the hydrogenerator. One of the turbines is connected with the rotor shaft of the hydro generator and the other to the shaft of the stator with opposite rotation. Each of the turbines is located in one of two separate parallel tubes receiving water. Turbine shafts are separate, horizontally, along a single line parallel to the dam, and secured in a pair of radial bearings. Between the bearings are slip rings and brushes. The design of the unit allows you to increase power while maintaining its size. 1 Il. Hydraulic unit with two non-axial, in separate tubes, turbines on separate horizontal shafts of the rotor and counter-rotating stator refers to the units (antrotomy), is intended to power.Analogue and prototype is antrotomy unit (hydraulic unit) (Polytechnical dictionary. / Chief editor A. Y. mechanics. - 2nd edition. Moscow: Soviet encyclopedia, 1980, S. 240). The prototype includes the Bina is located inside another shaft of the turbine). The generator rotor is attached to the outer hollow shaft of one of the turbine, the stator (contrator) attached to the inner shaft of the other turbine splined connection). The rotor and contractor (stator) of the generator rotate in opposite directions. The plane of the rotor and stator are parallel and closely approximated. The axis between the poles of the magnets are parallel to the shafts. Matching the characteristics of the prototype and the present invention: two turbines and rotating the hydrogenerator with cooling of the windings with the rotor attached (splined connection to the shaft of one of the turbine, and the stator with opposite direction of rotation, attached (splined connection to the shaft of the other of the turbine (the plane of the rotor and stator are parallel and closely approximated), with the axis between the poles of the magnets are parallel to the shafts. The reason which prevents the prototype to get the increased power of the hydrogenerator 4 times while maintaining its size, to ensure the effectiveness and fourfold compactness of the generator due to double the total speed of the rotor and stator and a small hydraulic losses is consistent placement of two coaxial turbines in a single tube. This is 2 times reduces the speed and 4 times reduces the capacity of the generator Jah, turbines on a separate horizontal shafts of the rotor and counter-rotating stator refers to the units (antrotomy), is intended to power. This invention provides a capacity increase of hydrogenerator 4 times while maintaining its size and in the presence of two separate non-axial turbines due to double the total speed of the rotor and stator (due to the opposite directions of their rotation), efficiency and fourfold compactness of the generator, the lack of hydraulic losses inherent in coaxial controlarea unit. This invention includes two turbines and rotating the hydrogenerator with cooling of the windings with the rotor attached (splined connection to the shaft of one of the turbine, and the stator with opposite direction of rotation, attached (splined connection to the shaft of the other of the turbine (the plane of the rotor and stator are parallel and closely approximated), with the axis between the poles of the magnets are parallel to the shafts. This invention from contrating unit (hydraulic unit) differs in that the turbine and the shaft is not connected coaxially one shaft is located inside the other), each of the two turbines is located in one of the two separate parali maintaining its size (if not changed number of poles) due to double the total speed of the rotor and stator (due to the opposite directions of their rotation), to ensure the effectiveness and fourfold compactness of the generator and the absence of hydraulic losses inherent in coaxial controlarea unit). The shafts are separate (not coaxial), horizontally, along a single line parallel to the dam, and secured in a pair of radial bearings. Between the bearings are electrical slip rings and brushes.Hydraulic unit with two non-axial, in separate tubes, turbines on separate horizontal shafts of the rotor and counter-rotating stator.Hydraulic unit with two non-axial, in separate tubes, turbines on separate horizontal shafts of the rotor and counter-rotating stator (graphic image) includes two turbines 1 and 2 and the rotary hydro generator 3 with the stator 4 with the electromagnets 5 with a cooled windings 6 and rotor 7 with a cooled windings 8. The rotor 7 is attached (splined connection to the shaft 9 of one of the turbine 1. The stator 4 with the opposite direction of rotation attached (splined connection to the shaft 10 other turbine 2 (the plane of the rotor 7 and the stator 4 are parallel and closely approximated). The axis between the poles of the magnets 5 and 11 parallel to the shafts 9 and 10. Turbines 1 and 2 and the shafts 9 and 10 are not soy is from two separate parallel tubes 12 and 13. The shafts 9 and 10 are separate (not coaxial), horizontally, along a single line parallel to the dam 14, and secured in a pair of radial bearings 15 and 16. Between the bearings 15 and 16 are electrical contact ring 17 and the brush 18.Turbines 1 and 2 convert the kinetic energy of the water into kinetic energy of the rotor 7 and oppositely rotating electric machine stator 4 hydro generator 3. The hydro generator 3 with the electromagnets 5 with the windings 6 of the stator 4 and the magnets 11 with the windings 8 of the rotor 7 converts the kinetic energy of rotation into electrical energy (electromagnetic induction). The shafts 9 and 10 connect the turbines 1 and 2 with the rotor 7 and the stator 4 (respectively). A separate tube 12 directs the flow of water on a separate (non-axial) turbine 1, a separate tube 13 directs the flow of water on a separate (non-axial) turbine 2. Individual turbines 1 and 2 accept individual streams of water. This allows 4 times to increase the power output of the generator 3 while maintaining its size (if not changed number of poles), as it provides double the total speed of the rotor 7 and the stator 4 (due to the opposite directions of their rotation), provides efficiency and fourfold compactness of the generator 3 and otstroennaya generator (3) proves his four power and compactness:
P = U2/R = v2B2L2/R
where P is the power generator 3 (without regard to the number of poles);
U is the voltage generated by the generator 3;
R is the electrical resistance of the windings 8 of the rotor 7;
v is the sum of the peripheral speed of rotation of the windings 8 of the rotor 7 and the magnets 5 of the stator 4 (without regard to the number of poles);
B - magnetic induction created by the magnets 5 of the stator 4;
L is the length of the windings 8 of the rotor 7.The formula for calculating the power generator 3 shows that the increase in total speed 2 times increases the power generator 3 to 4 times, while maintaining its size. This is equivalent to saving power generator while reducing its weight by 4 times (with the same number of poles and diameter). Dam of 14 creates the water pressure. The bearings 15 and 16 are fixed to the shafts 9 and 10 and reduce friction. Electrical contact ring 17 and the brush 18 output electric current (energy) of the rotor 7 and serves the electric current to the stator 4. The location of the contact rings 17 and brushes 18 between the bearings 15 and 16 provides additional compactness. The unit includes two turbines and rotary hydro generator with a rotor attached to the shaft of one of the turbine, and with the regatta, characterized in that each of the two turbines is located in one of two separate parallel tubes for receiving turbines separate streams of water, for increasing the power output of the generator while maintaining its size with the same number of poles due to double the total speed of the rotor and stator due to the opposite directions of rotation, for efficiency and compactness of the generator shafts are separate, horizontally, along a single line parallel to the dam, and secured in a pair of radial bearings between which are located the electrical contact rings and brushes.
