Description

The invention relates to the field of electrical engineering and physico-chemical technologies and relates to devices that are used for electrolysis of water.

A device for powering an electrolyzer is known, which is an electric generator (RF patent No. 2230197, IPC Н02К 57/00, 2004), containing brush-shaped electrodes with tungsten needles directed at each other and installed with a proper gap. The electrodes are mounted in a rectangular or cylindrical container, coaxial to each other. A perforated aerator-catalyst tube is installed at the bottom of the electrolytic tank; the tube is connected to the compressor. The capacity of the electrolyzer is connected by an inlet tube to a section of the condensate storage tank through a condensate line, to an electric pump and to a liquid alkali tank through a metering device, which is equipped with a solenoid and a time relay. In addition, the capacitance of the electrolyzer is connected through tubes to a plasmatron located in the ionization chamber, in which a plasma jet and water vapor reflector, a collector and steam tubes located at different angles of inclination and directed to the plasma jet are installed. The electrodes of the electrolyzer are connected to an alternating current source through an electric machine converter, an electric pulse sensor, and switches.

Also known is a device for producing electrical energy for water electrolysis, comprising a housing, a stator in the form of a magnetic circuit with a winding, a rotor and a current collector (RF patent No. 2284629, IPC Н02К 21/20, Н02К 31/02, 2006). In the known technical solution, radial electromagnets and circular electromagnets are installed in the generator excitation circuit, while the end magnetic circuits of both inductors rotating on the shaft of the generator rotor together with the radial and circular electromagnets face the opposite poles through the air gap to the magnetic circuits with the armature winding, which provides in the end magnetic circuits both inductors the constant presence of residual magnetism, contributing to the excitation of the generator, while the circuit The depot is equipped with two brush-contact units, including current collection brushes and continuous contact rings.

The closest in technical essence is a pulsed electromechanical power source (RF patent No. 2340996, IPC Н02К 57/00, 2006 - prototype), consisting of a housing in which an electric motor is installed, on the shaft of which there is a rotor with permanent magnets installed along the magnetic circuit stator windings, which are rigidly connected to the housing, and the magnets are located opposite each other with the possibility of ensuring penetration by the magnetic lines of force of the stator winding, while the inner surfaces of the magnets have r opposite poles, and used as a current collector terminals of the stator windings.

A disadvantage of the known devices is the separate layout of the electric motor and the electromechanical generator of electrical pulses, which complicates the design and increases mechanical loss.

The technical solution to the problem is to increase the reliability of the device by simplifying its design and reducing mechanical losses.

The solution to this problem is achieved by the fact that the electromechanical switching power supply containing a housing, an electric motor, on the shaft of which is located a rotor with magnets mounted along the stator winding magnetic circuit, rigidly connected to the housing, and current collectors in the form of stator winding leads, according to the invention, is equipped with an electromechanical pulse generator mounted on the shaft of the electric motor, having with the electric motor mounted on the shaft in its middle part a common rotor, the magnets of which are in quantity at least two are located along the stator of the electromechanical pulse generator, made in the form of a magnetic circuit mounted on the shaft of the electric motor, rigidly connected through rolling bearings to the housing, the stator of the electromechanical pulse generator is located inside the rotor, and the stator of the electric motor is above the rotor, while the stators have separate current collectors .

According to the scientific, technical and patent literature, no combination of features was found, similar to the claimed one, which allows one to judge the inventive step of the proposal.

Since the proposed technical solution can be applied in industry to save electrical energy during electrolysis of water, it can be argued that the proposal meets the criterion of "industrial applicability".

The invention is illustrated by drawings, where figure 1 shows a General view in longitudinal section of a pulsed electromechanical power source, figure 2 is a cross section of an electromechanical pulse generator, view aa.

The electromechanical switching power supply contains an electric motor 1 and an electromechanical pulse generator 2, which are located on one shaft 3 and have a common rotor 4, which is mounted in its middle part on a shaft 3, rigidly connected to the housing 5 through rolling bearings 6 and 7. Stator 8 of the electric motor 1 is located above the rotor 4, and the stator 9 of the electromechanical pulse generator 2 is located inside the rotor 4. The stators 8 and 9 have separate current collectors 10 and 11 and are rigidly connected to the housing 5. Magnets 12 of the electromechanical generator ora pulses of at least two stator arranged along an electromechanical pulse generator provided in the form of a magnetic circuit mounted on the motor shaft, is rigidly connected via bearings to the hull. The common rotor 4 in the part of the electromechanical generator of electrical pulses 2 has a smaller number of magnets (no more than 2, which are located opposite to each other, with the possibility of ensuring penetration by the magnetic lines of the stator winding, and the inner surfaces of the magnets have opposite poles) than in the part of the electric motor (not shown in the drawings). The number of magnets of the motor 1 can be 10, 20, etc. depending on engine design. The magnets of the rotor 4, interacting with the magnetic cores of the stators 8 and 9, provide a large duty cycle of the electrical pulses of the electromechanical generator. Separate current collectors 10 and 11 of the electric motor 1 and the electromechanical generator of electrical pulses 2 and the large duty cycle of the electrical pulses of the electromechanical generator 2 reduce the consumption of electrical energy for generating electrical pulses by the electromechanical generator and reduce the energy cost of electrolysis of water.

Electromechanical switching power supply operates as follows.

Voltage is supplied through the current collector 10 to the stator 8 of the electric motor 1. The common shaft 3 of the electric motor 1 and the electromechanical electric pulse generator 2 starts to rotate together with their common rotor 4. The magnets 12 of the rotor of the electromechanical pulse generator 2 interact with the magnetic circuit 9 of its stator and induce pulses in its winding voltage, which are removed from the current collector 11 and supplied to the electrolyzer.

It was found that the value of the mechanical moment of the rotor rotation resistance decreases in proportion to the square duty cycle of the electrical pulses. Since the current collectors of the electric motor and the electromechanical generator are separated and the mechanical losses on the drive of the electric motor and the electromechanical pulse generator having a common shaft and a common rotor are significantly less than the energy costs for generating the electric pulses by the electromechanical generator, as a result, the energy costs for driving the electromechanical generator of electric pulses are reduced in proportion squared duty cycle of pulses generated by an electromechanical pulse generator. This leads to energy savings on the drive of the electromechanical power source and on the electrolysis of water. As a result, the cost of hydrogen and oxygen obtained from water decreases.
