Abstract

A wind wheel of wind-driven power plant has a horizontal shaft on which outer cylinder course is installed, and conical axial splitter of air flow, between those blades are rigidly mounted, inner cylindrical ring that is rigidly connected to conical axial air splitter and horizontal shaft of wind wheel. At that between the outer and inner cylindrical rings blades of rig type are rigidly mounted.

Description

of the useless area of the sails to the area of the annular gap between the The essence of the useful model, which is claimed, is explained by the drawings: 0.6 to 10, and the ratio of the diameter of the inner circle - in Fig. 1, a schematic view of the cylindrical wheel of the wind wheel to diameter of the wind wheel on the side; of the inner cylindrical joint is from 1:2 to - Fig. 2 presents an isometric view of 6:7. windmills in front;

The blades of the sailing type, rigidly mounted between - in Fig. 3 is an isometric view of the external and internal cylindrical parts of the windmill from the back without a casing with a partial cut, create a dense sailing windmill, in windmills; which has an increased working area. Windwheel with - Fig. 4 shows the schematic effect of the flow due to the increased aerodynamic resistance of the annular air under increased wind load. of the sail slot when the wind vane is raised Windwheel 1 of a wind power installation, which does not ensure the passage of the entire volume is declared, has a horizontal shaft 2 install air and its excess goes outside the windwheel, len on a vertical rack From the rotary frame 4 without creating overloads from torque of the wind power plant along the axis of its rotation. relative to the wind direction. Behind the windmill 1 is installed

At the ratio of the diameter of the inner cylindrical executive mechanisms (not shown in the figure), the wind wheel's inner diameter to the outer diameter is covered by a casing 5. The windmill 1 has an outer 6 and a cylindrical sleeve within the stated limits - an inner 7 cylindrical sleeve, between which are moving, we move the air flow from the center to the fixed blades 8 of the sailing type, the conical periphery of the windmill with the help of a conical axial air flow splitter 9, a rigidly connected axial air flow splitter, we get a chenie with an internal 7 cylindrical shell and the center of application of the wind force on 5/6 of the radius west- horizontal shaft 2 with the help of the radial area spitted by the windmill, while increasing the wind speed by two beams 10. times, that the wind turbine The wind wheel of the wind power plant drives the area, while increasing the speed by two times as follows. of the wind passing through the annular sail gap - When the wind hits the windmill, at the expense of well. In the preferred option of increasing the twisting own aerodynamic resistance, the windmill of 1 moment in comparison with the blade of the windmill of the prototype is turned towards the wind flow. The flow is (5/6)x2/(/1/2)-3.6 times for each blade, where the air moves from the center to the periphery, the center of force application: 5/6 of the radius for the invention of the windmill using a conical axial distribution , which is declared, 1/2 radius for the prototype; 2 - air flow splitter 9, while the ratio of the filling of the blades to the captured frontal resistance decreases and the wind speed increases, which is the area of the invention to the prototype. When approaching, it passes through the annular sail gap. The torque of the filling factor increases to 0.6-10. The moment from the horizontal shaft of 2 windmills is destroyed. The aerodynamic resistance of the annular gap is due to the multiplier of the hydrostatic trans-air flow with a speed of movement greater than the mixture or an electric generator (not shown in Fig. 18m/sec. . The excess amount of air, without having it possible) and is transferred to the executive mechanisms (in Fig. the gusts pass through the annular sail gap, exit is not shown) for the performance of technological filters beyond the boundaries of the outer shell and bypasses the wind shears. leso, without creating a torque higher than When the wind speed increases higher than the calculated one. calculation (Fig. 4) an excessive amount of air cannot

Due to the increase in aerodynamic resistance, the windmill can work in any range of the windmill, which ensures its preservation. winds At the same time, the blades of the wind turbines operating in the sail mode (the movement of the blade is less than the speed of the installation, which is declared, with small, normal wind) do not create high-frequency oscillations, they and increased wind loads have harmful effects on humans , which allows you to establish high efficiency and reliability, at the same time it allows you to wind the windmill next to residential buildings and obtain the necessary torque by windmill enterprises. sa and the maximum coefficient of energy production z

Parts of the windmill can be made from the wind flow, without having a harmful effect on the cradle of soft metals and alloys such as duralumin, or duralumin, thanks to which it can be used for thin sheet stamped to give shape and obtain environmentally clean renewable energy of stiffness of stainless steel, or synthetic in in close proximity to residential and industrial buildings reinforced with glass or synthetic roof structures. And, in addition, it allows to be curtains, as well as fabrics based on them. completely autonomous for any business, as well as safe for birds due to the low frequency of rotation of the windmill.
