The invention relates to wind power and can be used in the creation of wind power stations, but also for driving deep pumps for lifting water. The technical result consists in simplifying the design of an installation with increasing its efficiency and improving reliability in operation due to the fact that in a wind plant comprising a concentrator, a flow accelerator, a rotor with blades, according to the invention, the concentrator is made in the form of a hollow cylinder with vertical through slits , The concentrator interacting with a flow accelerator positioned inside it in the form of guiding elements made in the form of smoothly bent plates connected to each other in a ring, the ends of the plates being smoothly bent and forming slots coinciding with the slots of the concentrator, in addition, the ring is made With the ability to move around the vertical axis, and inside the ring is made at least one rotor with blades.
DESCRIPTION OF THE INVENTION
The invention relates to wind power and can be used in the creation of wind power plants, but also for the drive of deep-water pumps for the duration of water lifting. A wind-powered high-speed aggregate is known, consisting of a generator whose stator is located inside the rotor and fixed to a fixed hollow axis, and the outlet part of the channels of the air intake device is provided with nozzles enclosing the rotor (Patent of Russia 2032832, F 03 D 9/00, F 03 D 3/04 From 12.02.1991, published on 10.04.1995). The disadvantage of this wind turbine is the low coefficient of wind energy use. A wind turbine is known comprising a flow concentrator in the form of a telescopically dual confuser with a curved vortex chamber, a flow accelerator and a rotor with elliptical turbo blades and telescopically retractable blades (Patent of Russia No. 2078995, F 03 D 9/00 of May 26, 1992, published on 10/05/1997 - prototype ). This wind turbine has an increased efficiency of using wind, but it is difficult to manufacture and operate, but also insufficient reliability in operation at high wind speeds.
The task of the proposed invention is to simplify the design of the plant with increasing efficiency, and reliability of the plant.
This problem is solved by a wind power plant including a concentrator, a flow accelerator, a rotor with blades, according to the invention a concentrator made in the form of a hollow cylinder with vertical through slots, the concentrator interacting with a flow accelerator inside it, made in the form of guiding elements made in the form of a smooth Curved plates connected to each other in a ring, the ends of the plates being smoothly bent and forming slits coinciding with the slots of the concentrator, in addition, the ring is arranged to be moved around the vertical axis, and at least one rotor with blades is inside the ring.
Analysis of the proposed solution with the prototype allowed to distinguish features that distinguish the proposed solution from the prototype, which corresponds to the criterion of "novelty". Comparative analysis of the proposed solution with the known did not reveal solutions whose characteristics coincide with the characteristics of the proposed solution, which corresponds to the criterion of "inventive level".
The invention is explained in the drawings, in which FIG. 1 shows a general view of the wind farm, FIG. 2 shows a section along AA, and FIG. 3 shows a flow accelerator. FIG.

The wind power plant includes a concentrator 1 made in the form of a hollow cylinder, a flow accelerator 2, a rotor 3 with blades 4. Vertical through slots 5 are provided in the concentrator 1. A flow accelerator 2 is provided in the concentrator 1 in the form of guiding elements 6 made in the form Smoothly bent plates connected to each other in the ring 7, the ends 8 of the plates 6 being smoothly bent and forming the slits 9. The ring 7 is movable about a vertical axis by a special mechanism (not shown in the drawing), for example, by means of a rack with a serrated Wheel.
WINDOWS WORK AS FOLLOWING
A wind farm is installed, for example, on the roof of a building (car, etc.). The airflow (wind) penetrating through the through slots 5 of the concentrator 1 enters the slots 9 formed by the smoothly bent ends of the plates 6. And since these slots are made in the form of a confuser and a diffuser, the air stream compressing accelerates its movement, while The air is ejected and a larger airflow passes through the slots 9 than through the through slots 5 of the concentrator 1. Therefore, in the cavity formed by the ring 7 in front of the rotor 3, in the direction of air movement, an excessive air pressure is created, and behind the rotor 3, the normal atmospheric one. Excessive pressure acts on the blades 4 of the rotor 3, which starts to rotate. The exhaust air is discharged through the through slots 5 of the concentrator located on the opposite side in the course of air movement. Rotors 3 can be several. The diameter of the concentrator increases. With increasing wind speed, in order to avoid breakage of the rotor 3 or blades 4, the ring 7 rotates about a vertical axis, for example, by means of a rack and a gear wheel, while the guide elements 6 partially overlap the through vertical slits 5, reducing the air pressure on the rotor blades 4 3. In case of a hurricane wind, in order to avoid breakage of the rotor 3 or blades 4, the ring 7 is rotated until the through vertical slots 5 are blocked by the guiding elements 6. Thus, the air stream penetrating through the through vertical slots 5 of the concentrator 1 will flow around the ring 7 And be discharged through the same slots from the back of the concentrator 1.
This performance of the wind turbine makes it possible to simplify the design and increase its efficiency. In addition, such a wind farm can be permanently installed both on the roofs of multi-storey buildings and on the roofs of moving objects, for example rail cars for generating electricity, and a wind turbine can be used to drive deep-water pumps for lifting water.
