MULTI-VOLTAGE WIND POWER STATION

MULTI-VOLTAGE WIND POWER STATION

The name of the inventor: Fedchishin Vitaly Grigorievich
The name of the patentee: Fedchishin Vitaly Grigorievich

Date of commencement of the patent: 1993.12.14

Use: in wind power and can be used to create new types of high-power wind farms. SUMMARY OF THE INVENTION: The supporting frame is made in the form of interconnected three rotatable masts inclined to the central axis, the central and lateral rotors being connected by cables through blocks to the winch drums and held in the upper position by retractable clamps.

DESCRIPTION OF THE INVENTION

The invention relates to power engineering and can be used in the creation of high power wind farms (VES).

Rotary systems known as Darje, Masgrove and the type "Zhyromil" are known [1]

A multi-rotor wind power station is known, comprising a supporting frame, an outer carriage with rollers arranged in parallel guides, a lifting carriage cable connected via a block to the drum of the ground winch [2]

The aim of the invention is to increase the efficiency of leeward ("shaded") rotors and simplify rigging during the installation of wind farms.

The goal is achieved by the fact that the supporting frame is made up of three inclined masts rigidly connected at the top by ties, and at the bottom rotatably with brackets of foundation blocks, each of which is equipped with a winch with two paired alternate drums, one of which is connected through the upper block to one From the arms of the hull of the central wind farm, and the cable of the other with the carriage of the side wind turbine, while in the upper (working) position the central wind-driven unit is additionally held by three, and each side platform by one, remotely controlled retractable fixators. The cable of each side carriage is connected to a spring-loaded pivoting cam that stops the carriage when the rope is accidentally weakened or broken.

The author does not know the sources of scientific and technical and patent information containing information on similar technical solutions that have features similar to those that distinguish the claimed solution from the prototype, but also properties that coincide with the properties of the claimed solution, so we can assume that it has significant differences , Allowing in practical implementation to create new powerful and convenient in operation wind farm.

In Fig. 1 shows: a) side view; C) the clamp of the central wind power unit; C) the locking device of the side carriage.

In Fig. 2: a) top view; C) fixing the rollers to the carriage; (C) Top view of the winch.

In Fig. 3: a) fastening the guide cable to keep from swinging the central rotor when it is raised or lowered; C) the way of lifting one of the turning masts during installation of the wind farm.

The multi-rotor wind farm contains four twin rotors (central 1 and lateral 2-4) with vertical axes of rotation.

The multi-rotor wind farm additionally comprises three double-support swing masts 5, each of which is connected at the bottom by trunnions 6 to brackets 7 and is kept in a vertical position (under a slight inclination to the central axis) by means of masts 8.

The tops of the masts 5 of the frame 9 are connected to each other by ties 10 and bolted connections 11, forming a rigid hexagonal contour.

The central rotor 1 is connected by three brackets 12 through the blocks 13 by means of cables 14 to the drums 15 of the winches 16 and locked in the uppermost (working) position by remotely controlled retractable latches 17.

Each of the lateral rotors 2-4 is disposed on a separate horizontally located carriage 18 connected through the unit 19 via a cable 20 to the drum 21 of the winch 16. The bases of the carriages 18 are held in the guides 22 by means of the rollers 23 and are provided with stopping devices: a working 24 and a cable Anti-damage 25. The reduction gear 26 of the winch 16 is provided with a switching sleeve with an outwardly driven handle 27, by means of which the reels 26 or 15 are alternately connected to the reduction gear 26.

Each frame 9 has a U-shaped vertical frame 28 with a block 29 and a remotely controlled sliding lock 30, on top of each vertical frame 28 there is a bracket 31 connected through an opening in the bracket 12 by means of a guide cable 32 and a tensioning device (lanyard) ) 33 with bracket 34 foundations.

MULTI-ROUTINE VES WORKS AS FOLLOWS:

The masts 5 assembled from the component sections are placed on the installation site angularly at 120 ° relative to each other and after connection of the pins 6 with the brackets 7 are alternately raised and connected to each other.

After lifting the rotors to the upper position, the mutual kinematic connection between the rotor blades is remotely closed, and therefore they are spontaneously installed relative to the wind direction with the required orientation.

In this case, no additional adjustment of the rotors is required.

The carriages 18 can have the following design:

Stationary (I);

With a change in the distance from the rotor to the central axis (II);

With transverse movement of the carriage relative to the mast and additional displacement of the rotor on the carriage (III);

With balancing two rotors placed on the lateral outer sides of the transverse carriage (IV).

Once installed on separate carriages, the rotors operate as stand-alone wind turbines.

In regions with a frequently changing direction of the wind, variants II and III of the design of carriages are more preferable.

In order to obtain the maximum output power without increasing the occupied area, two rotors can be placed on each carriage, simultaneously balancing each other (IV).

The central rotor has two working positions I and II (Figure 1, a). When the central rotor is positioned in position II, there is no need for radial or lateral movement of the side rotors on the carriages.

The tensioned guide cables 22 protect the central rotor from swinging during its lowering or ascent.
