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 H02K 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 coaxially 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 H02K 21/20, H02K 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 H02K 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 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 a pulsed electromechanical power source 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, while the electric motor and the electromechanical pulse generator are mounted on the shaft in its middle parts of the common rotor, whose magnets are at least two in part of the electromechanical pulse generator located along its stator, made in the form of a magnetic circuit mounted on the shaft of an electric motor rigidly connected through rolling bearings to the housing, and the stators of the electromechanical pulse generator and electric motor 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 pulsed electromechanical power source contains an electric motor 1 and an electromechanical pulse generator 2, which have (Fig. 1) a common external rotor 3, mounted in its middle part on the shaft 4 of the electric motor 1. The stators 5 of the electric motor 1 and 6 of the electromechanical pulse generator 2 are made in the form of magnetic cores are located on the same common shaft 4 and have separate current collectors 7 and 8 in the form of terminals of the windings of the stators 5 and 6. The shaft 4 and the stators 5 and 6 are rigidly connected to the housing 9 through rolling bearings 10 and 11. On the inner surface The two rotors 12 are opposed to each other in the part of the rotor 3 in the part of the electromechanical pulse generator 2, so that the stator windings can be pierced by magnetic lines of force, and the inner surfaces of the magnets have opposite poles, which allows it to work with a greater duty cycle of electrical pulses, and reduces the moment of resistance to rotation its part of the rotor is proportional to the squared duty cycle of the pulses and reduces the consumption of electrical energy, for example, for electrolysis of water. On the rotor 3, the magnets 12 of the electromechanical pulse generator 2 and the magnets (not specified) of the motor 1, which may be 10, 20, etc. depending on the design of the engine, located along the magnetic circuits of the stators 5 and 6 of the electromechanical pulse generator 2 and electric motor 1.

Switching electromechanical power source operates as follows.

Voltage is supplied through the current collector 7 to the stator 5 of the electric motor 1. The shaft 4 of the electric motor 1, on which the electromechanical pulse generator 2 is mounted, starts to rotate together with their common external rotor 3. The magnets 12 of the rotor 3 of the electromechanical pulse generator 2 interact with the magnetic circuit of its stator 6 and induce in the winding of the magnetic circuit voltage pulses that are supplied to the electrolyzer through current collectors 8.

It was found that the value of the mechanical moment of resistance during rotation of the rotor decreases in proportion to the square duty cycle of electrical pulses. Since the electric motor 1 and the electromechanical pulse generator 2 have a common shaft and a common rotor, and the current collectors are separated, the mechanical losses on the drive of the electric motor and the electromechanical generator of electrical pulses are significantly less than the energy costs for generating an electromechanical generator of electrical pulses. As a result, the energy consumption for driving an electromechanical generator of electrical pulses decreases in proportion to the square duty cycle of the pulses, which leads to savings in electrical energy for driving an electromechanical power source of the electrolyzer. In addition, the cost of hydrogen and oxygen obtained from water is significantly reduced.
