Description

The proposed utility model relates to the field of wind energy, in particular, to wind motors with an axis of rotation perpendicular to the direction of the wind and with a movable diffuser.

Closest to the claimed utility model and adopted by the authors for the prototype is a wind turbine installation (VTU) containing a friction type rotor made in the form of a shaft placed vertically with the possibility of rotation of the rotor inside the housing and provided with plates installed one relative to the other at a given vertical distance (see A.S. No. 2240442, Cl. F03D 3/00). The VTU case is made in the form of a guide apparatus. The input edges of the guide vanes are rotatable and connected to the weather vane.

The disadvantage of the prototype is the low efficiency and lack of wind flow concentrators.

The technical problem solved by the proposed device is to increase efficiency and ensure the concentration of air flow.

The problem is solved in that the known wind turbine installation containing a rotor made in the form of a shaft, placed vertically, with the possibility of rotation inside the housing of the guide apparatus, according to a utility model is equipped with a diffuser, the outer surface of which is made in the form of a truncated pyramid, and the inner surface consists of two parts: internal confuser and internal diffuser, the junction of which is the outer edge of the guide vane, consisting of vertically arranged blades, avnomerno

fixed around the circumference between two flat disks at an angle relative to the rotor blades, made in the form of rims, with the help of spokes attached to the shaft on which the generator is located, and at a predetermined vertical distance relative to each other with blades uniformly fixed between them, the installation is additionally equipped with a monorail made in the form of a closed circle coaxially with the rotor shaft, on which the diffuser output rests with the possibility of movement along it.

The figures show a wind turbine installation:

Figure 1 is a horizontal section of a wind turbine installation;

Figure 2 is a vertical section of a wind turbine installation;

Figure 3 - the location of the rotor blades and vanes of the guide apparatus.

The installation comprises a rotor 1 (figure 1, 2), made in the form of a shaft 2 (figure 1, 2) placed vertically inside the guide apparatus 3 (figure 1, 2) with the possibility of rotation in the bearings 4 (figure 2). To the shaft 2 with the help of knitting needles 5 (Fig. 1), the rims 6 (Figs. 2, 3) are attached at a predetermined vertical distance from each other. Between the rims 6 uniformly fixed around the circumference of the blade 7 (Fig.1, 3). The guide apparatus 3 consists of vertically arranged blades 8 (Fig.1,3), which are uniformly fixed around the circumference between two flat disks 9 (Fig.2, 3). The blades of the guide vane 8 are located at an angle relative to the blades of the rotor 7. On the same shaft with the rotor 2 there is a generator 10 (figure 2). The diffuser 11 (figure 1, 2) is designed in such a way that it can rotate around the axis of the shaft 2 around the circumference of the monorail 12 (figure 1), being oriented according to the direction of the wind. The inner surface of the diffuser 11 consists of two parts: the internal confuser 13 and the internal diffuser 14, the junction of which is the outer edge of the guide apparatus 3.

The device operates as follows.

The air flow, accelerated in the internal confuser 13 due to the discharged air at the outlet of the internal diffuser 14, passing through the blades 8 of the guide apparatus 3, flows in the tangential direction to the package of blades 7 of the rotor 1. When it moves in the gaps between the blades 7, wind energy, thanks the forces of surface friction and aerodynamic interaction are transmitted to the package with blades 7, which causes the rotor 1 in rotational motion. The air flow moving toward the center, having given energy, exits in the radial direction through the slots in the guide apparatus 3. Using the generator 10, all the energy is converted into electricity.

The technical result achieved by the implementation of the utility model consists in the fact that at high specific values of the wind turbine installation its cost is reduced, the dimensions of the rotating parts are reduced and the efficiency is significantly increased due to the presence of a diffuser 11 made of an internal confuser 13 and an internal diffuser 14 concentrating the flow air in a certain direction.
