The invention relates to the field of power engineering and can be used in the construction of low-pressure or non-pressure river power plants, tidal or wind power plants.

Known orthogonal energy unit containing the orthogonal turbine blades hydrodynamic profile, fixed between the flat rings, and generator, while the orthogonal turbine made bunk, with each tier turbines are made with blades sagittate shape, curved spiral lines and symmetrically inclined from the vertical in opposite to the blades adjacent tier orthogonal turbine direction, the ring located between the adjacent layers, the pinned ends of the blades of both tiers of the orthogonal turbine (see patent RU 2380566, CL F03B 13/10, 27.01.2010).

In this orthogonal energy unit achieved a sharp reduction reaction loads that occur during operation of the orthogonal turbine with blades hydrodynamic profile, which allows to increase the reliability and efficiency of the unit. However, this unit does not fully use the energy of the incident driving environment - air or water, which reduces the energy efficiency of water or air flow.

The closest is to the invention of the technical essence and the achieved result is an energy unit, with a vertical tower is made in the side wall which the blade apparatus for forming inside the tower swirling whirling motion of rolling tower flow moving environment, and from the side of one of the end faces of the tower in the axial region last entered the outlet pipe, at least one channel, to increase the rotation, and in the channel of the installed turbine, the shaft of which is connected to the generator (see patent US 4070131, CL F03D 7/00, 24.01.1978).

In this power unit is mostly used energy flow. However, the supply channels in the axial region of the vertical tower in the axial direction leads to an increase of hydraulic losses and, consequently, to decrease the energy efficiency of the unit.

Task to be solved by the present invention is directed, is the reduction of hydraulic losses during the energy conversion flow of water or air during its flow through the power unit.

The technical result is achieved by improving the energy efficiency of the unit by increasing the utilization of the kinetic energy of flow of water or air

This problem is solved and the technical result is achieved due to the fact that orthogona the capacity energy unit includes a vertical tower with made in the side wall which the blade apparatus for forming inside the tower swirling whirling motion of rolling tower stream of the moving medium, and from the side of one of the end faces of the tower in the axial region last entered the outlet pipe, at least one channel, and the channel is installed turbine, the shaft of which is connected to an electric generator, an outlet pipe, at least one channel, to increase the rotation introduced in the axial region of the tower in the direction of rotating inside the tower environment, the channel section from the inlet to the turbine is made tapering, turbine made orthogonal multi-tier, each tier turbines are made with blades sagittate shape, curved spiral lines and symmetrically inclined from the pair of adjacent blades tiers in the form of the tip of the boom in opposite to the blades adjacent tier orthogonal turbine direction, the ring located between adjacent layers, the pinned ends of the blades adjacent tiers of the orthogonal turbine, the output section of the channel is made with the axis parallel to the direction of the vortex flow inside the tower, and the axis of the output section of the channel is located from the axis of the vertical tower at a distance of 0.3 to 0.6 of the radius of the tower in the transverse section passing through the output section of the channel.

Cross-section of the channel is made, preferably, rectangular, and the axis of the output section of the channel may be located in horizontal the real plane of the cross-section of a vertical tower.

The blades, which device is preferably arranged vertically in a circle around the vertical axis of the tower can be rotated, acting on the end of each blade is fixed to the vertical plate forming together with the blades in cross section of the blade smoothly streamlined G-shaped

The blades, which device can be made hollow with the ability to use them as pneumotachometer.

Cavity of the blades can be connected to the compressor.

By the end of the vertical tower opposite end, where there is at least one channel, can be installed deflector made in the form of a concave in the direction of the end face of the vertical tower plates forming the latter with the end face of the tower gradually narrowing in the direction of the vertical axis of the vertical tower of the flow part.

The channel can be performed with multiple output sites located at different levels along the height of the vertical tower.

In the course of the study identified the possibility of creating orthogonal energy unit, which allows to ensure that the conversion of the energy of wind or water flow, in which the incident on the vertical tower flow within a vertical tower in the whirlwind, giving the store a decrease in pressure in the center of the vortex 7-10 speed of the heads of the oncoming free stream. In this channel, the outlet pipe which is introduced into the tower in the direction of rotation of the vortex, made mostly of rectangular cross-section and the axis of the output section of the channel is located from the axis of the vertical tower at a distance of 0.3 to 0.6 of the radius of the tower in the transverse section passing through the output section of the channel that allows you to collect, in the case of wind energy, the air is heated from the bottom layers of the atmosphere outside of the vertical tower and sends it inside the tower tangent to the vortex, rotating inside the tower above the zone of maximum pressure reduction, which increases the stability of the vortex in the vertical tower and allows to reduce the relative height and to increase the efficiency of the unit. At the location of the outlet area closer than 0.3 of the radius of the tower is unable to make full use of an area of low pressure due to the increasing turbulence in the flow in the zone of the outlet area with the formation of counter-flows. If the location is further than the 06 on the radius of the tower, the pressure rise along the inner vertical walls of the tower does not create any significant pressure drop, which would increase the efficiency of the unit. In the result set in the channels multilevel orthogonal turbine type with the arrow-shaped blades can trigger standard, gearless and brushless generators with speed from 375 to 3000 rpm (for different capacities and modifications), and described a multilevel orthogonal turbines provide at any position of the turbine is practically constant in time, the total resistance to the flow and balancing of the turbine is achieved using the swept blades that not only provides constant torque, but the constancy forces support reactions, and the use of balanced turbines with swept blades and small Shader channels eliminates multipliers and apply standard high-speed and high-efficiency generators.

Thus, the orthogonal energy unit allows to generate electricity for electrification of Autonomous objects in remote and inaccessible regions of the country, as well as for high-power electrical systems, including hydroelectric power plants as objects of storage and backup power.

The blade, which blade device can be made hollow with the ability to use them as pneumotachometer that allows you to accumulate air from the high pressure in the variable energy of the windmill or provide buoyancy orthogonal energy agrega is and when it is used as a hydraulic system.

Performing orthogonal energy unit with deflector allows the use of the latter as to provide additional low pressure in the center of the vertical tower (ejection), and to prevent the promotion of the vortex outside of the tower.
