Description

Description of the invention

The invention relates to the field of wind energy, namely to wind energy installations of the orthogonal type. 2 A similar rotor of a wind engine is known (application FRG 3734106, class ROZO 33/06, printed 04.27.89) with a vertical axis of rotation, which is formed in the form of a cylinder with plate blades fixed on it with a constant step perpendicular to the radius, coaxial with the shaft rotor, a rotating air flow guide device is installed on it.

The disadvantage of this wind engine is low operational reliability, since the central shaft is loaded by the lateral force from the wind load, which acts on the air flow guide device, in addition to 70 of its own load. It causes a cyclic alternating load on the central shaft, fatigue of the metal and the possibility of its destruction.

As a prototype, an orthogonal type wind power installation was chosen (patent of Ukraine Мо18214 А, РЕ 03 О 3/01, 9/00, printed on 12/25/97), which contains a rotor with a vertical axis of rotation, which is formed in the form of 12 cylinders with a central shaft, vertical blades, which are fixed on it with a constant pitch, the lower support of the central shaft contains a cardan joint with a bearing, the upper support of the cable type with a bearing in the housing is connected by radial rods with brackets, which are located on the tail parts of the end ribs of all the rods of the sectional guide device of the air flow and fixed with the possibility of adjusting the length on the brackets, which are installed on the bow parts of the following rudders, and the last brackets are connected by tension cables with eyebolts, which are embedded in the fundamental blocks. A sectional air flow guide device with convex-concave agrodynamic profile baffles, which are installed around the rotor in the form of a circular deflector with a fixing gap from the rotor with slots in a clockwise direction and fixed stationary with bolted connections to the foundation blocks. The drive to the electric generator contains a free-wheel clutch, a multiplier, an inertial battery, shafts, pulleys, clutches 22. "

The disadvantage of the wind power plant is the limited efficiency (efficiency), since the limited power of the generators does not allow to fully use the maximum kinetic energy of a strong wind at a speed of 5Ω/s.

The invention is based on the task of improving the wind energy installation, in which the conversion of the kinetic energy of the wind at any speed, including 5Ω/s, is ensured by converting the mechanical work of the rotating impeller into thermal energy in the boiler, and due to this, the coefficient increases efficiency (efficiency) of the wind energy installation, hot water is provided for heating homes, apartments, greenhouses, etc. with

The task is solved by the fact that the wind energy installation, which contains an impeller with

With" a gap, slots along the course of rotation of the clock hand, according to the invention, the lower shaft of the cardan hinge is made in the form of a vertical rod with bearing supports on the upper and lower bottom of the thermal boiler with water and contains radial blades fixed in rows on the side surface at an angle A to its asi, which are installed with a minimum interval of 5 from the rows of blades, and fixed at an angle Я on the inner side surface of the heat boiler, connected by pipelines through a float valve to a waste tank with water, with (os heating batteries, with faucets of the bathroom, shower , sinks, the installation is equipped with an electric generator, which is installed in a carriage with rail guides and interacts with the help of a toothed mesh with a gear,

Ф which is fixed on the upper shaft of the Cardan hinge. (in 50 It is these distinguishing features from the prototype in combination with other significant features that allow to increase the efficiency of the wind power plant, using the wind speed range from sl 2 to 5Ω/s

Fig. 1 shows a cross-section of a wind power plant; Fig. 2 - cross-section A-A of Fig. 1; Fig. 3 is a section B-B of Fig. 1; in Fig. 4 - node 1 of Fig. 1; in Fig. 5 - node 2 of Fig. 1. 99 The proposed orthogonal wind power plant (Fig. 1) contains an impeller 1 with vertical blades 2, vertical axis of rotation Z, central shaft 4 with upper support 5

Byte type, which is connected by radial rods 6 to brackets 7, 8, located on the upper ends 9 of the slats 10 of the sectional air flow guide device 11. Customs 10 have a convex-concave aerodynamic profile 12 and are installed around the impeller 1 in the form of a circular deflector 13 with 60 slots 14 in a clockwise direction (Fig. 2). The lower support 15 of the central shaft 4 contains a hinge

Cardan 16 with a bearing 17, which is fixed on the upper bottom 18 of the boiler 19. Under the lower support 15 there is a dense cuff 20 with a pressed ring 21. The lower shaft 22 of the Cardan 16 hinge contains radial blades 23 fixed in rows on its side surface at an angle A to the axis , which are installed with a minimum gap of 5 from the rows of blades 24, fixed at an angle Y on the inner surface of the boiler 19. The lower end 25 of the lower shaft 22 is installed in the support 26, which is fixed on the lower bottom 27 of the boiler 19

(fig. 5)

The hot water supply system from the boiler 19 includes a hot water pipeline 28, which is connected to the heating radiators 29, the bathroom ZO, the shower 31, the sink 32, the return water pipeline 33, the cold water pipeline 34 from the pump, the flow tank 35 is connected by the pipeline 36 with heat boiler 19. At the lower end of the central shaft 4, a gear 41 is fixed, which interacts with a gear wheel 37, fixed on the output shaft of the electric generator 38, which is installed in the carriage 39 with the possibility of movement along the guide rails 40 (Fig. 1)

The wind power installation works as follows: 70 The air flow of the oncoming wind blows from the outside the sectional air flow guide device 11 (fig. 1, 2), the nozzles 10 of which separate the air flow into the left part of the flow and the right part of the flow (in the direction of the wind) . The left part of the air flow, which passes through the narrow gaps between the convex-concave slats 10 of the air flow guide device 11, blows the vertical blades 2 (Fig. 2) of the impeller 1, while the right part of the flow is delayed, shielded by the slats 10 and /5 Leaning to the right from the guide device 11 does not blow the right, back part of the blades 2.

Due to the difference in the pressure of the high-speed wind pressure on the left and right parts of the impeller 1, the moment of rotation M about occurs. Relative to the axis of rotation Z according to the course of rotation of the clock hand. The torque is transmitted by the central shaft 4 of the impeller 1 through the cardan joint 16 to the lower shaft 22, which rotates in the bearing supports 15 and 26 inside the boiler 19, which is filled with water to a certain 2o level. Radial blades 23, which are fixed on the lower shaft 22 with a minimum gap from the blades 24 installed on the side surface of the thermal boiler 19, move water in the thermal boiler 19. The friction of the blades 23 against the water, the water against the blade 24 and against the walls of the thermal boiler 19 and friction layers of water between each other causes the water to heat up. The transformation of the mechanical work of the rotating shaft 22 with blades 23 inside the boiler 19 with water obeys the "Law of Conservation of Energy"! According to R. Mayer-G. Helmholtz, the "Mechanical equivalent of heat" is equal to 427 kHm per 1 kilocalorie, and 1 kilocalorie corresponds to 4.2 joules. Hot water through pipeline 28 enters heating radiators 29 of housing, greenhouses, bathroom, shower, sink. Water circulation in the heating system is ensured by radial blades 23, which are installed at an angle to the axis of the lower shaft 22, like a fan. The consumption of water from the boiler 19 for the bathroom, shower, sink is replenished through the float valve from the waste tank 35, into which water is supplied by the pipeline 34 from the pump (or water supply). In order to light the house, it is necessary to turn on the electric generator 38, which moves the carriage 39 along the guide rails 40 to the engagement of the gear wheel 37 with the gear 41 on the lower shaft 22. In normal times, the electric generator is turned off and the wind power plant works in autonomous water heating mode. "at

The wind power plant has the following advantages compared to the prototype: 1. It increases the efficiency (efficiency) due to the use of the entire range of wind speeds up to 5Ω/s. "E 2. Allows to convert the mechanical work of the wind power plant into thermal energy in an autonomous mode, without human intervention.

C. It expands the possibility of using wind turbines to obtain heat, electricity, and water supply, which is important for autonomous agriculture and farming. "
