The invention relates to a battery power supply, and in particular to methods of use of the fluid in the pipeline for the generation of electric power.

This method is designed for power automation devices piping (valves, sensors) water supply systems, gas and oil pipelines.

There is a method allowing the supply of such devices, where energy conversion is carried out by pressure pulsations in the flow. How is that pressure pulsations in the pipe compensate by converting energy of a fluid flow so that the energy conversion of fluid flow in the hydraulic shock carried out partially into electrical energy, using the property of the piezoelectric elements to produce an electrical charge when their deformation, and the remaining part of the energy offset due to the deformation of series-connected elastic or viscoelastic elements (RU 2422715 C1, RF, MPK F16L 55/045).

The disadvantage of the described device is the inability to work offline and the lack of automatic regulation of liquid flow.

A known way of converting the flow energy (EN 2424444 C1, RF, MPK F03B 3/00, F03B 13/00):

- the way of energy conversion was, namely, that the conversion done by what is by changing the translational motion of the flow into rotational motion of the fluid and the rotor of the turbine, moreover, this change of movement is determined by the formation of two vortices of opposite rotation direction, where the conversion is carried out by changing the translational motion of the flow into rotational motion of the fluid and the rotor of the turbine in a limited from the main stream of the first stage due to cutting off the water flow to the turbine and the gradual narrowing of the conduit to increase the speed of the translational movement, the second phase is due to the rotation of the water simultaneously around two axes lying in perpendicular planes, rotation around the rotor axis of the turbine and vortex process veroobrazno form the basis of the limited volume, the third stage is due to the formation accelerated upward rotation-and-forth flow directed to the unwinding of the rotor and performs regenerative function.

- the way of energy conversion was according to claim 1, where the conversion is carried out with the possibility of the formation of rotation as many additional radial vortex flows, leading to an effective redistribution of energy was.

- vortex turbine containing a frame with vertically located a hollow container which is placed in the PTO shafts installed one above the other two blade that the bins, coaxially to the axis of rotation, and the inner wall is made in the form of a pipe of variable cross-section with the formation of the tapering upward channel, where the vertical hollow container fixed and made in the form of glass form a bottom in the form of polutropos surface, forming in the bottom of the axial through hole in the upper part of the glass on its periphery installed nozzle input input socket, parallel to the direction of the primary was the first turbine blade located on one level with nozzle input, a radial, the second turbine blade axial performed.

- vortex turbine according to claim 3, where the blades of the first turbine is equipped videobrasil surfaces, and the opposite surface of the glass is a reflective annular zone.

- vortex turbine according to claim 3 or 4, where the vertical wall of the nozzle with variable cross-section with the formation of confused, narrow, cylindrical and cone parts.

To implement this method, there are several various designs, however it does not provide for the accumulation of energy to power the device itself or other elements of the valves.

The prototype was taken to the patent of the Russian Federation 2431758 C1 IPC F03B 13/00, F03B 17/06. This method of generating electricity includes bringing in the movement of the magnets relative to the part of the windings of insulated conductive wires under the action of the energy of water flow, supplied through the conduit and discharge voltage windings, which in pulsating mode, change the water pressure in the conduit, causing the throbbing walls of the conduit and lead magnets that are installed on or in the walls of the conduit in a radial reciprocating motion, acting field magnets winding.

The disadvantages of this method is that to get the power you need to call a water pressure surge in the pipeline and its walls, which negatively affects the quality of water and causes increased wear of the pipeline system.

It is assumed that electricity consumers are divided into two groups: low power, operating long-term (the first type) and higher power working short-term (the second type). Based on this, you want a system that will allow the conversion of mechanical energy of the flow into electricity, which you will be able to accumulate and use for power systems automation pipelines.

The objective of the invention is to provide a method for converting mechanical energy derived from the exhaust portion of the fluid flow, electrical, which can be used to power elements of the automation devices and actuators valves pipelines.

Supplied with the I problem is solved using the method of obtaining energy for power automation devices pipelines, which is to move the permanent magnets relative to the coils of insulated conductive wires under the action of energy of the fluid in the pipeline and discharge voltage windings, where the magnets result in rotational movement under the action part of the fluid flow directed into the turbine, which produces the conversion of flow energy into mechanical energy to rotate the shaft of the generator and turn mechanical energy into electrical energy and then electrical energy transform, accumulate and exercise power.

Figure 1 shows the block diagram of the system.

The proposed method is carried out using a system that consists of turbine 1, generator 2, the power converters 3, 5 and the drive power 4. To generate electricity is used selected from the main thread portion of the fluid generated in a separate thread. For this purpose, the turbine 1 is installed in otodrom channel 6. The formed thread in otodrom channel results in rotational movement of the turbine rotor 1, resulting in the energy of the fluid flow is converted into mechanical energy, which is then converted into electricity using an electric generator 2. Recent falls in the static Converter SPA 3, which is for the realizatsii charging of power storage 4 net-EN, later in SPA 5, where the conversion of this energy to a form convenient for use by consumers.

The method of obtaining energy for power automation devices pipelines, which consists in bringing the movement of the permanent magnets relative to the coils of insulated conductive wires under the action of energy of the fluid in the pipeline and discharge voltage windings, characterized in that the magnets result in rotational movement under the action part of the fluid flow directed into the turbine, which produces the conversion of flow energy into mechanical energy to rotate the shaft of the generator and turn mechanical energy into electrical energy and then electrical energy transform, accumulate and exercise power.
