The proposed method of conversion relates to power engineering and can be used to convert the mechanical energy of motion of a fluid medium in electrical energy.

A method of converting wind energy (fluid) into electrical energy, which device is illustrated comprising a support, elements-transducers of mechanical stress into electrical signals (pulses) based on piezoelectric elements, and the battery electrical energy, wherein the elements-transducers mounted in the flexible fabric of the cloth, mounted on a support device, and flexibly connected to pianoconcerto-Converter impulsive electrical signals into a DC voltage which is connected to the electricity consumers (RU 2297710 C1, 20.04.2007). Specified known method of transformation may serve as a prototype of the proposed method.

The disadvantage of this method is the mechanism for converting translational motion of the fluid in oscillatory motion by means of flexible panels with built in elements such as transmitters. The presence of flexible cloth requires sufficient space for the implementation of such oscillations, it is necessary to ensure the mechanical strength of the cloth and flexible joints in it when you did not comply with the�chivay the condition of flexibility of the cloth, depending on external conditions - temperature, humidity, possible mechanical damage.

The technical result of the proposal is to convert the translational motion of the fluid in the oscillatory motion of this fluid, followed by converting mechanical oscillations into electrical oscillations in a solid-state device with no moving mechanical parts to produce electrical energy.

The technical result is achieved in that in the process of converting mechanical energy of a fluid medium in electrical energy translationally moving the fluid serves to jet generator, transform it in the translationally moving the fluid in oscillatory motion, the output of the jet generator converts the oscillatory motion of the fluid transducer of mechanical stress into electrical signals, which then convert the current Converter in unipolar electric current and is served to the consumer.

Implementation of the proposed method is explained by the diagram in the drawing.

The schema contains 1 - jet generator, 2 and 3 control channels, 4 and 5 - feedback channels, 6 - cavity jet generator, 7 - a Converter of mechanical stress into electrical signals, 8 and 9 - the drain holes 10 and 11 of the discharge channels 12-current Converter, 13 - power consumer, a 14 - unit conversion.

The fluid serves to meet the jet generator 1, orienting it relative to the fluid flow, for example, with wind vane (not shown). Under the action of alternating control signals on the control channels 2 and 3, flows through the channels 4 and 5 feedback, the fluid oscillates in the cavity 6 of the jet generator providing alternating impact on both sides of the Converter 7. The spent fluid from the jet generator is discharged to the outside through the discharge openings 8 and 9 through the channels 10 and 11. Electrical impulses from the transmitter 7 is received in a current Converter 12 and obtained a unipolar current is fed to the electricity consumer 13, such as battery electrical energy. Jet generator 1 with a Converter 7 and a current inverter 12 form a unit conversion 14 mechanical fluid energy into electrical energy, which can be made in a single solid-state performance.

A method of converting mechanical energy of motion of a fluid medium into electric energy, characterized by the fact that in the process of converting mechanical energy of a fluid medium in electrical energy translationally moving the fluid serves to jet generator, convert� in it translationally moving the fluid in oscillatory motion, at the outlet of the jet generator converts the oscillatory motion of the fluid transducer of mechanical stress into electrical signals, which then convert the current Converter in unipolar electric current and is served to the consumer.

SUBSTANCE: invention relates to wind power engineering and may be used to produce wind energy and convert it into electrical, mechanical, thermal energy or their different combinations. Air flow is captured from wind and accelerated in a narrowing channel, and is supplied into a device with a water jet by a pump, where water and air flow is produced. The water-air flow is accelerated to supersonic speed, and is then turned into subsonic water-air flow of the fuel. Energy is extracted from the specified subsonic flow in the turbine, and then the flow arrives into the receiving reservoir, where water and air are separated. The residual pneumatic energy of the separated compressed air is additionally converted into electrical or mechanical energy. The residual thermal energy of compressed air and water is used accordingly for air and water heating or hot water supply.

EFFECT: usage of the invention makes it possible to exclude a blade wind turbine, to reduce weight and dimensions of a device, to increase reliability and to ensure uninterrupted power supply to loads with various types of energies.

SUBSTANCE: invention relates to the field of heat power engineering and may be used to provide hot water supply and heating of buildings and structures located in areas with no centralised heat and power supply. A thermal wind turbine comprises a rotor wind engine with a vertical shaft, which transmits rotary motion via a reducer to a round plate, to which vertical cylindrical partitions are fixed at the bottom, being submerged into a heat insulated tank with water. Cylindrical partitions are also fixed to the bottom of the tank, and partitions fixed on the round plate move between those. Water arriving into the tank, flowing via movable (rotary) and fixed partitions is heated due to friction. Since the gap between movable and fixed partitions is chosen as minimum possible for water passage, water heating is carried out quite effectively, which is also supported by a roll arranged in the form of a net increasing friction made on the surfaces of cylindrical partitions. Blades mounted on the outer side of the external (relative to the central axis) movable (rotary) cylindrical partition help to pump water into the outlet nozzle of the tank and back to the load.

EFFECT: higher efficiency.
