WIND-HEATING AND HYDROGEN

Date of commencement of the patent: 1992.06.23

Use: in the field of energy, to create new converters of wind energy or water into electricity. SUMMARY OF THE INVENTION: The wind turbine comprises a co-axially installed second similar wind turbine with an orientation of the blades that rotates its rotor in the opposite direction from the upper one, and the nonrotating windmill cases are attached to each other on a cruciform frame joined by the ends of the brackets with a supporting frame located outside the trajectory of rotation of the blades. For a high-altitude wind power station, the supporting frame is secured from below by an aerostat held by cables and raised or lowered by a lifting cable with a winch. When the wind turbine is placed on a ship (instead of sails and in addition to them), the supporting frame is fitted with a trunnion with eyelets on the bracket and holds the cables, occupying the minimum useful space on the deck. With the coaxial installation of several wind turbines above each other, their supporting frames are fixed to each other and mounted on a platform of the mast held by three twin cables in an upright position. For the hydrogenerator, the supporting frame is fixed from below the floating platform, which is held afloat or set to depth using cable ropes attached to the bottom ballast anchors.

DESCRIPTION OF THE INVENTION

The invention relates to power engineering and can be used in the creation of new converters of wind and water energy into electricity.

A wind turbine is known, which includes a housing, a rotor reducer, blades, a worm gearbox, a weathervane, a drive gear and gears of energy converters (electric generators), and a conical central nonrotating pinion, kinematically connected by satellite links in the form of a two-section shaft with conical gears Driven by conical gears, on whose shafts the blades are paired in pairs (top and bottom) and both parts of each of the satellite shafts are connected by a releasable coupling, the movable sleeve of which through the pusher, the conical sleeve, eccentric and the flag is connected to the central axis, the bracket with contact groups connected Two springs with freely positioned on the axis of the weather vane, the electromagnetic tappet of the cone bushing.

However, such an electric motor generates uncompensated twisting forces acting on a non-rotating body.

It is an object of the invention to provide a powerful wind energy converter or water flowing system to an electric one, which provides balancing of the axial deployment forces of the housing for the possibility of securing the supporting frame to the wire rope stretching or a balanced installation on the deck of the vessel.

This goal is achieved by the fact that the wind power unit additionally comprises a co-axially installed second similar wind turbine with an orientation of the blades that rotates its rotor in the opposite direction from the upper one, and the non-rotating windmill cases arranged by the bases to each other are fixed to a cross-shaped frame connected by the ends of the brackets to an out- Rotation of the blades with a supporting frame.

When using a wind turbine as a high-altitude wind farm (VES), its supporting frame is fixed from below to the balloon held by wire ropes at the required height. Lifting and lowering of the balloon is carried out by means of a lifting cable fixed to the supporting frame, and on the bottom of the winch drum, while simultaneously it supports the power and remote cables.

To accommodate the wind power unit on the deck of the ship (instead of sails or in addition to them), a landing pin with eyes attached to the bracket is provided in the lower part of the reinforced frame, while the wind turbine held in vertical position by four cables (stretches) practically does not occupy a useful space on Deck.

The structure of the supporting frame provides the possibility of a coaxial compact multi-tier installation (vertical modular build-up) of several wind turbines, which allows to increase the output power in the same proportion, without occupying an additional floor at the same time.

When the wind turbine is used (in hermetically sealed and reinforced version) as a hydrogenerator in the non-navigable sections of shallow rivers, the supporting platform remains afloat and anchored, and in deep sea currents and in the channels, the platform is set to the required depth and held by cables fixed in a stretch to Ballast bottom cargo or anchors.

The author does not know the sources of patent and scientific and technical information that contain information about similar technical solutions that have features similar to those that distinguish the claimed solution from the prototype, and 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 a new type of wind turbine and its modification of the hydrounit.

FIG. 1 shows the appearance of a wind turbine with a bearing frame; In Fig. 2 high-altitude wind turbine with a wind-driven aerial hanging to the balloon; FIG. 3 shows a variant of installing a wind power unit on a walking catamaran; FIGS. 4 and 5 show a pairing of four wind turbines on a cargo and passenger vessel in two projections; In Fig. 6 schematically shows multi-stage high-power wind farms installed on high masts; FIG. 7 shows the arrangement on the flexible connections of a sealed hydraulic unit in places of intense undercurrents (I position when towing to the installation site, II position afloat before immersion, III working position at depth).

Wind turbine contains wind turbine 1 without mast and platform. The wind power unit additionally comprises a second wind turbine 2 coaxially installed and deployed 180 degrees downward (with a weathervane), and the bases 3 and 4 located to each other are located on a cross-shaped frame 5, the ends of the brackets 6 of which are connected to the supporting frame 7 fixed to the high-altitude wind farm by the rods 10 To the rim 11 of the balloon 12, on the deck 13 of the ship with cables 14 and a pin 15 to the bracket 16, with a multi-tiered arrangement on the platform 17 of the mast 18; In the hermetic version in the form of a hydraulic unit 19 under a floating or depth-mounted platform 20. The balloon 12 is held laterally fixed at six places along the contour of the rim 11 by three twin cables 21, and in the center by a cable 22 connected by clamps 23 to the cable 24 and fixed at the bottom to Drum winch 25.

The submarine cable 24 is held along the shortest path to the shore by enclosing floats and is connected to a distribution substation 26.

WINDOWS WORKS AS FOLLOWING

Before installing the wind turbine, the blades of both wind turbines 1 and 2 are set in such a way that the plane of each upper blade 27 is perpendicular to the plane of the blade 28 below it. This should usually be done when the planes of the weather vanes 29 and 30 coincide, i.e. Spontaneously (Fig.1), and then automatically, regardless of the change in wind direction.

In contrast to a sailing vessel with a wind turbine, it is possible to move directly against the wind (in the leftist), to continue the movement in the calm due to the consumption of the accumulated excess energy, and constantly replenish it, even in high winds, including in open winds . Exhausting team work with rigging here and eliminated.

In the hydrogenerator version, the vane systems of orientation in a unidirectional flow are absent as unnecessary, and the initial orientation of the blades is carried out from the control panel of the distribution substation 26 via a cable by the remote inclusion of worm gears connected to the central non-rotating axis kinematically connected to the blades.

The pre-set orientation of the blades excludes this operation.
