Abstract

The wind vortex wall consists of at least a pair of multi-rotor turbines (2), the shafts (3) of which are mounted on the partitions (1) clamped on a rear beam (4), the weight of which is supported in several points by the cables (8) guided from above a front beam (9). A surface (7) initiates two opposing vortices, which collide and amplify the flow at the site of the multi-rotor turbines (2). The wind wall enables the economical application of wind energy capacities to mountains, seas and buildings.

Description

Technical field

The technical solution concerns wind vortex walls for capturing wind energy and converting it into electricity without the need for large turbine blades and without the need for permanent foundations.

Prior art

The conversion of wind energy is currently applied mainly by means of large-diameter three-bladed rotors placed on towers with a height approximately the size of the rotor diameter. The towers are anchored in foundations or floating platforms, which must withstand extreme load moments. Large diameters cause an exponential increase in weight and at low speeds the demands on an expensive transmission system. The high weight of these components limits the economy and environmental friendliness of the production and installation of equipment, especially in the mountains, so the most advantageous high speeds.

The essence of the technical solution

The essence of the technical solution are a pair of multi-rotor wind turbines - each with a common shaft. The shafts are placed on a support structure consisting of front beam, rear beam and crossbars, with front and rear beams . The lower parts of the front beam and the rear beam are connected on a rotating axle at the top of the column. The lower part of the shafts opens into rectangular gears and the torque is further transmitted to the center to the generator, which may have a rotating housing and a counter-rotating shaft.

Below the front beam is a suspended surface which initiates at its edges the formation of induction vortices, which are maintained by the flow of air over the entire rectangular vortex wall. Two opposing vortices formed on the gutters and inclined surfaces collide in the middle of the wall and accelerate the flow through the multi-rotor turbines in a direction close to the axis of the turbines.

On the partitions, the buoyancy surfaces in the functional wings between the pairs of turbines and their flow direction around the edge edges accelerate the eddy currents and optimize the flow direction according to the variable angle of attack.

The buoyancy forces from the buoyancy surfaces create a counter-moment against the resistance forces from the wind, so that the resultant of the vector sum of forces is in the plane of anchorage of the column or at the level of the water level.

The surface under the front beam has a corrugated shape reinforced by transverse stripes and is suspended on ropes in each corrugation. This makes it easily portable and harmonically compressible into a transport shape.

Examples of embodiments

The mountain wind vortex wall is designed for the use of favorable wind conditions in the mountains without harm to the environment and without higher costs during installation and massive foundation. The column 10 is only clamped in the middle of its height by three struts or ropes and the construction is rotatably mounted on its top from the air. Both the front beam 9 and the rear beam 4 are divided and joined by ropes 8, so that they have a low weight similar to multirotor turbines 2, which have a low diameter and thus exponentially lower weight. The surface 7 suspended below the front beam 9 concentrates the flow and creates a vortex flow around the vortex wind wall. It is transported to the top of the mountain or ridge separately in the closed state, during assembly it expands harmonically to a higher span and the inductive flow of vortices around the extreme edges increases the active front diameter of the active wind. In relation to the basic frontal section, the achievable efficiency of the conversion of wind kinetic energy into electricity generated by generator 5 after transmission in rectangular gears 6 with input from shafts 3 driven by multi-rotor pairs of turbines . Buoyancy surfaces on the partitions 1 increase the vortex effect and optimize the flow direction on the turbine blades 2. Overloading by excessive wind is eliminated by the so-called by battling the buoyancy surfaces around the partitions 1 as well as the surface 7 by the elasticity of the rear reinforcing ropes. Buoyancy buoyancy2

With K 8944 Υ1 surfaces, it allows the entire rotating part to be directed directly on the vertical axis in the direction of the wind direction.

Another embodiment of the technical solution is a floating wind vortex wall. All functions are as in the previous example, with the post 10 being a hollow floating buoy, the upper half of which is above the surface up to a height of 20 m, the lower half being clamped by ropes to the seabed. The low weight of the system and the torque-free post 10 5 in the shape of a hollow tube make it possible to reduce the cost of the platform and its attachment.

Another embodiment is a small wind farm on a flat or saddle roof. The height of the column 10 is chosen so that the vortex wall itself is in the zone of highest flow around the edge of the roof. Area 7 is not necessary if a microturbine of 0.5 to 1 kW is applied. The vortex wind wall can be used to heat water in the boiler and heat the building directly or via a heat pump. The capacity factor is about 2.5 times higher in winter 10 than with solar systems. The application of hybrid systems of vortex wind walls and solar collectors is ideal. The medium-capacity design can be operated on high-rise buildings, preferably by simply clamping the column 10 with cables anchored on vertical walls.

Another embodiment is a wind source for electrically powered ships. The side of the ship serves as a surface 7 and creates an upward current to the wind vortex wall in crosswinds. Sailing is also possible in the headwind at a reasonable speed. The ship can serve as a charging station, which is kept in the headwind without anchoring by means of multi-rotor propellers and consuming part of the power. The front beam 9 and the rear beam 4 can be telescopically retracted, the wind vortex wall as a whole can be pivoted on the ship in the direction of the propeller.
