INVENTION
Russian Federation Patent RU2070662
DEVICE Wind Turbine
Name of the inventor: Kharitonov Valentin; Kharitonov, Igor V.
The name of the patentee: Kharitonov Valentin; Kharitonov, Igor V.
Address for correspondence:
Starting date of the patent: 1994.04.13
Usage: used in the wind industry. The inventive device comprises a windmill tubular support, flexible shafts with blades, shafts kinematically connected with an electric generator. The supports are set in an area of the cell order interconnected flexible shafts, arranged symmetrically with respect to the supports and in parallel with each other.
DESCRIPTION OF THE INVENTION
The invention relates to wind energy. The purpose of the invention, decrease of metal, increasing the efficiency in the construction of wind turbines (windmills) high total power.
FIG. 1 shows a wind power plant unit (WPU); FIG. 2 is a section AA of Fig. 1; FIG. 3 a schematic representation of the wind turbine at a constant wind direction; FIG. 4 schematic representation of wind turbine in variable wind directions, top view; FIG. 5 a schematic representation of wind turbines in mountainous terrain, in cross section in FIG. 3.

Turbine comprises a tubular support 6 stretched between two supports flexible shafts in the bearings 1. Along the flexible shaft 2 are alternately disposed impeller 3 made in the form of a plate with elastic side member 7 mounted thereon envelope 8 (see. Fig. 2). The outer ends of outer blades 3 are provided with balancing counterweights 5. During twisting and bending of the shaft 2 are eliminated by the drawn blades 3. Flexible shaft 2 energy is converted into electrical power generator 4 through the multiplier 9 and transmitted through electrical cables 10 to the step-up transformer 11. In order to protect by weathering equipment (multiplier, generator, power and control cables, 12 service staircase) is mounted inside the tubular support 6. The tubular supports 6 mounted on the base 14, are mounted on the perimeter of angled extensions 13.
The proposed technical solution multiplier involves the installation of vertical supports 6 of tubular form in size in a cellular manner interconnected flexible shafts 2 arranged symmetrically with respect to the supports and in parallel with each other, the distance between the flexible shaft 2 in a vertical plane by a height of the supports and hence the blades size 3 located on flexible shafts, increases from the ground, while flexible shaft 2 provides the function of stretching between adjacent supports 6 that maximizes the energy of the wind in the upper part of the air flow.
At constant wind direction honeycomb supports advisable to mount elongated wind direction perpendicular to the front (FIG. 3), at varying wind directions supports 6 may be mounted on the circuit of Fig. 4 (top view), which provides for any direction of the wind can be rotated about the same number of flexible shafts with blades 2 and 3, respectively, to produce a constant amount of electricity. Installation of the supports (cell procedure) in mountainous areas (Fig. 5). The distance between supports wind turbine is determined by the settlement, depending on the maximum wind velocity, and the tensile strength and used construction materials. Wind Turbine proposed design allows the use of standardized steel tubular support, the same types of flexible shafts with blades, stretching, same type of electrical equipment, quickly and economically build large wind turbines of total power.
