The invention relates to vetrogidroenergetica plants, which convert the energy of air and water flow into electrical.Known confused wheel along.with. N 1550206 F 03 D 1/04. The energy potential is determined by the input confusor diameter, which is not protected against ingress of foreign objects on the blades of the propeller. The scheme design has no aerodynamic qualities that reduces its reliability when the storm winds and limits the extent to which energolecenie. the multi-items, being in the flow, which limits the scope of energolecenie and durability.It is also known a device for the application N 94022974 IPC 6 F 030 D 5/00 containing the turbine and generator, the diffuser, the site of the diversion of the flow behind the turbine, axial fairing outer shell located over the site of the diversion of the flow.Implementation the design of this device is a complex technical task, which will require the use of high-precision aviation equipment and technology. This relates primarily to the manufacture of parabolic axial shell 1 and axisymmetric annular channel 8.The possibility of ingress of foreign objects in the stream, at the mouth of the diffuser 2 reduces the reliability and durability of the installation, increases operating costs.The opening of the air flow on the bottom slice of installation affects the aerodynamic quality, resulting in complicated by the possibility of orientation of its flow. Stripped thread on this cut leads to undesirable vortex formation and loss of energolecenie.The aim of the invention is to simplify the design of the device and the zoom is against installation turboelectric module (TDM).TDM contains the first 1 and second 2 fairings, the ends of which are connected to the power jumpers 3, the ring confused belt 4, policosanol 5, which is installed turbine 6, the axis of which is the generator 7, the protective device 8 and the keel 9.When working TDM Kiel 9 orients the device to flow, the orientation can be carried out in any known manner.The flow of the medium (air or water), passing area of the annular active zone (KAZ) between cones 1 and 2, located on the diameter of the device at a speed greater than the speed of free environment due to the compression lines flow around the chassis TDM, creates a pressure difference in KAZ. Confused ring 4 located above the gap between the ends of the fairing 1 and 2, forming the working area, also contributes to the concentration of energy flow, which leads to a further increase in flow rate in the working area, inside the fairings movement speed environment is close to zero, so in the cavities of the fairings and the pressure exceeds the pressure in the flow inside the annular confused belt 4. This leads to the fact that the air (or water) inside the cavity of the fairing 1 and 2 will be extended through Protanopia turbine 6. The flow of air (or water) goes through the turbine from the other open end policosanol device 5 and enters the cavity of the fairing, and then out through the gap between the ends of the fairing 1 and 2 in the free stream at the output diameter of the ring confused belt 4.The energy of the device is determined by the square of the input diameter of the ring confused belt 4.The optimal ratio of the diameters of the belt 4 and the diameters of the ends of the fairing 1 and 2 are determined during the development of working drawings of the device. The device can be used in air and water environments.1. In the air as the wind turbine to generate electricity.2. In the conditions of the ocean and sea currents. We offer cylindrical construct more sophisticated in comparison with the installation of "Coriolis - 1" described in the book A. Goldin "Oceans of energy" M. "Knowledge" 1983, page 87.The proposed construction will increase the problem of increasing energolecenie in the stream.The average size of wing assemblies, rotary vane (Daria) and rotary with rotary blades leads to reverse economic result.There is blunt the ASS="ptx2">The increase of the same size (diameter) of the fairings of the device leads to a proportional increase in energolecenie.In addition, the use of a combination of turbo-generators with storage units will allow you to use the full energy of storm winds at wind speeds higher than the wing or rotor units. Bell and confused units - "the mighty wind" - does not withstand any criticism regarding environmental performance, aerodynamics and, respectively, economic feasibility.Offer turboelectric module will expand the range of flow rates.The turbine will operate at very low wind speeds, for example when V = 1 - 2 m/s, and will function properly when the storm winds, if the generator load on accumulating Energoproekt known type.The protective device 8 installed at the entrance of petokomorna 5, eliminates the possibility of ingress of foreign objects in the stream, such as birds, respectively, increased sustainability and reduced costs of operation of the device. Turboelectric module for air and water potokovom, and the ring confused the belt, characterized in that turboelectric module contains the first and second fairings located ends some distance between them, United power jumpers, forming an annular active zone in diameter, above which is located at some distance ring confused belt, and a protective device mounted on the input end of policeservice.
