Definitions
- the invention relates to the field of wind energy, that is, to installations that produce electrical energy through the use of airflow force.
- the main disadvantages of this installation are: significant metal consumption, the drive of the generator shaft from the horizontal axis of rotation of the wind wheel through the gearbox, and the fact that the working blades of the wind wheel are mounted on the fingers and spring-loaded, that is, they can change the spatial position depending on the wind speed.
- the objective of the invention is the creation of a compact, portable (mobile) wind power installation that provides the generation of electrical energy at low (over 4 m / s) air velocity.
- the technical result of the invention is to reduce the weight of the wind power installation and the possibility of generating electrical energy at low (over 4 m / s) air velocity.
- a rotary device is made in the form of a multi-segment diffuser mounted on a power ring with an input an opening having a diameter smaller than the diameter of the outlet.
- the wind wheel has blades with an aerodynamic profile twisted in length
- the installation is equipped with a base plate pivotally connected to the support, and the diffuser segments and the wind wheel blades are made of composite polymer materials.

- FIG. 3 shows its layout
- FIG. 4 is a diagram of an assembly and installation in a working position of a wind power installation.
- a wind power installation (hereinafter referred to as a wind turbine) (Fig. 1) contains a wind receiving part 1, including a power (mounting) ring 2, a support 3, a rotary device 4, a self-orienting diffuser 5, consisting of several segments 6 with tie straps 7, a pylon 8, a generator 9, a rotor 10 of an electric generator mounted for rotation, a shaft-stator 11, a blade 12, a cooker 13, a fairing 14, a wind wheel 15, a support plate 16, a support section 17, cable ties 18, steel crutches 19, the front of the diffuser 20, rear of diffuser 21, hinge 22, flange connected 23.
- a wind receiving part 1 including a power (mounting) ring 2, a support 3, a rotary device 4, a self-orienting diffuser 5, consisting of several segments 6 with tie straps 7, a pylon 8, a generator 9, a rotor 10 of an electric generator mounted for rotation, a shaft-stator 11, a blade 12, a cooker 13, a fairing 14, a
- the support 3 consists of several sections 17 made of pipes interconnected by flanges 23. It is fixed and supported in vertical position by cable braces 18 with screw pairs 25.
- a support plate is installed with a hole in the center, for passing the lower part of the rotary device 4, with a pylon 8 installed on it.
- a pylon 8 is mounted on which a reverse circuit generator 9 is fixed, that is, its housing containing permanent magnets rotates, and the shaft with wires is stationary.
- a hinge plate 22 is welded for mounting purposes.
- the multi-segment diffuser 5 of circular cross section in the front part 20 has a cylindrical shape, passing in the rear part 21 in cylindrical larger diameter, which creates an aerodynamic effect, leading to the main technical result of the invention (figure 2).
- a support plate 16 is made with a support stand 26 welded to it, at the end of which a plate is welded for swiveling with a plate-hinge 22 of the support 3.
- Segments 6 of the diffuser 5 are formed by a "sandwich” type structure, placed around the outer circumference of the power (mounting) ring 2, fixed with their grooves and pulled together with bandage bands-ties 7 based on a polymeric material, for example, capron.
- the blades (blades) 12 of the wind wheel are mounted on the generator body with fastenings in the form of a “dovetail”, which makes it convenient to mount or remove them.
- the blades are made of a composite material, for example, fiberglass, by the laying and pressing method, and have a calculated twist angle.
- Blades of the wind wheel and diffuser segments made of composite or combined materials greatly reduce the noise level of the installation due to their absorption of acoustic vibrations from air flow disturbances.
- the wind power installation operates as follows.
- the diffuser is self-orientating towards the oncoming air flow without the use of additional devices, such as a remote flat vane (wind vane).
- the used air flow is forcedly formed by the diffuser so that the speed of the air flow running onto the blades of the wind wheel installed in a narrow section of the diffuser increases sharply compared to the flow rate at the inlet of the diffuser, which increases the speed of the wind wheel.
- the power of the used electric generator is from 1 to 1.5 kW, which allows the unit to be used for the autonomous supply of electricity to individual houses, cottages, radio centers, meteorological stations (posts), remote cattle pastures, tourist camps, etc.
- a base plate 16 is installed horizontally along the level gauge and fastened by driving four (in the corners of the plate) steel crutches 17 into the ground.
- the first lower section 17 of the support 3 is attached to which the subsequent sections are fastened inside the section 17 of the electric cable and brake cable (not shown in Fig.) Using a flange connection 23 until the required height of the support 3.
- a rotary device is mounted, in the eyes of which the ends of the extensions 18 are attached with screw pairs 25 unscrewed to the stop.
- Climbing is recommended in relatively quiet, slightly windy weather.
- the stretch marks (three pieces) are spread apart at an angle of 120 ° to each other and their second ends connected with crutches driven into the ground are pulled by screw pairs, and the hinge-plate 22 is connected to the upper mounting plate of the rack 26 the base plate is fixed with bolts and nuts.
- Dismantling and disassembling wind turbines are carried out in the reverse order.
