Abstract

The wind turbine (2) comprises the blades in a horizontal position and is located on top of a concentric trough composed of the blocks (12). The front arms (9), a lower arm (14) and an upper arm (3) are connected by the ropes (5) to increase the resistance to bracing. A fan (4) and a balance (8) in controlled position change remove the moment load on a base (11) with a wind axis (10) of the wind power system. The low weight and the low torque load allow for portability of the device without the need for the stable foundations.

Description

Technical field

The technical solution relates to wind-energy systems for placement in economically problematic areas or hard to reach areas.

BACKGROUND OF THE INVENTION

Vetemo-energy systems use various construction elements of turbines, masts and anchors. Three basic types of turbines are turbines with horizontal axis, vertical axis and in conjunction with concentrator The most common are turbines with horizontal axis two- and three-blade. The application of low power at low altitudes is problematic due to the increase in specific costs. The problem is also to apply wind-energy systems in hard-to-reach places with difficult foundations or anchoring platforms (mountains, seas). Paradoxically, just in places with even and intense winds away from the dwellings.

The essence of the technical solution

The essence of the solution is to place a wind turbine with blades lying on top of the gutter with a wind energy concentrate, which comprises blocks drawn by drawbars pivotally mounted on ropes, which stiffly form a system between the front arms, lower arms and upper arms. The pulling of the ropes in conjunction with the weight alone or additionally reinforces the strut strength of the load-bearing structure. The swinging blocks maintain the channel shape for the nominal wind. Above its value they are opened by control or flexibility of the connecting rods. At the end of the upper arm, a wing with an angle of attack upstream of the air flow vectorized from the horizontal flow and the upward flow above the wind turbine from the residual concentrated flow is located. The wing is attracted from below by a tether with a branch on its span. The lashing rope is attached at the bottom on the bottom, which is on a rotating seed base. The vertical sections of the sash and the swivel axis allow the wind direction.

The stability of the wind power system is also maintained by servomotors on the front arms, which control the position of the weight depending on the wind force. The weight will move forward with increased flow, increasing system rigidity in conjunction with wing lift at the end of the upper arm.

EXAMPLES

A wind power system in a small wind power plant for placement in rugged terrain.

The wind turbine 2 with the generator 1 is light weight without a gearbox, without a blade turning mechanism, which allows a higher concentrated air flow and a horizontal position of the blades. The generator 1 is mounted on a lower arm 14, which is supplied to an upper arm 3, on which a concentric trough composed of blocks 12 is attached. Each block 12 is clamped separately and pivotable on any of a plurality of ropes 5 which are preloaded by the weight of the device; additional. This makes it possible to increase the bracing resistance of the lower arm 14 and to reduce its weight at a relatively high position of the wind turbine 1. The low mass blocks 12 in sufficient quantity are resistant to wind force due to the small unit size. With nominal wind in the trough closed state, with excessive wind in the trough open state, which allows the blocks 12 (Fig. 3) to be swiveled by pulling the resilient drawbars 13. On the resiliently curved upper arm 3, the wing 4 is secured over the lashing 6 . The wing area 4 is determined by its position and decreases with the height and oblique intensified air flow over the wind turbine 2. Its buoyancy adds vector resistance with the wind concentrate and the resultant is directed to the base 11 without the torque load of the axis 10 which is the whole wind power system. in the wind direction by the vertical part of the wing 4.

Another embodiment of the wind-power system is a high-performance power plant on a mountain top or on a floating platform. The balancing torque is supplemented by the weight of the weight 8, whose position is variable with the wind force under the influence of the servomotor 7, which may have the design of a savonius turbine with a winch and

S K 8637 U1 Booster The wind force sensor is dropped, the turbine pulls the weight to the end of the front arms 9 in proportion to the wind force. The low residual load torque on the axis 10 simplifies laying and anchoring both in the mountains and in the seas by laying the foundation 11, the complete elimination of the moment of forces at the root of the system allows the wing angle of attack 4 to be controlled according to the wind force. Thus, the foundation 11 is only loaded by a force without torque 5 and the weight of the device, which can thus be fitted from the air by lowering the bearing into the base 11, the load being additionally inflated, or using a weight 8 lowered to be secured. . This allows the construction of wind farms even at depths of over 200 m without the need for demanding anchoring of the torque load of the platform.

The weight of the wind-energy system according to the technical solution is 10 to 20 tons per 1 MW. Another stage of assembly is the lay-up and lift by rotating at the pivot point of the foundation by pulling the end of the front arms 9. The low weight of the device and the base 11 makes it possible to operate the wind power systems as portable at low power without categorization.
