Abstract

Wind turbines (wind turbines), which are created on land or in the coastal apron, use the wind power to thereby drive the rotor blades of the plant so that electricity is generated in a generator. Since the wind does not blow constantly strong, but also weak wind befalls occur, this time can not be used to generate electricity. By storing the energy in strong winds, the weak-wind bevel can be bridged. The storage of energy is achieved by the following invention, characterized in that each wind turbine has its own tower on which the machine house is mounted, the tower can be integrated as an important part of construction. In order to be able to make optimal use of the tower, weights (5) / (6) are installed in the inner or outer side of the wind turbine tower (3) and are fastened to traction ropes.

Description

Wind turbines are designed as wind turbines (WTG) / wind turbines (wind turbines) to use wind energy by the wind setting the rotor in motion and generating a generator of electrical energy, which is then fed into a grid. The rotor and the machine house are mounted on a mast, which reaches in different lengths, partly up to 140 m height. Wind turbines can be used in all climates. They are created on land (onshore) and in offshore wind farms in the coastal apron of the seas. The mast can be constructed as a concrete mast, as a steel mast, as a steel lattice mast, as a wooden mast or in hybrid construction.

The power of common systems is around 2 to 5 MW for onshore installations and 3.5 to 8 MW for offshore installations. Even systems in the power range from a few 100 watts to several kW can be economical.

The specified in the protection claim 1 invention is based on the problem of using the wind range in strong winds so that excess energy is stored in order then to use the stored energy at windstep.

This problem is solved with the features listed in the protection claim 1.

With the invention it is achieved that for the excess energy a construction, namely the existing tower of the wind turbine, with weights, winches with motors and pulleys for storage is available.

By controlling the plant it is achieved that the existing excess wind supplies energy to lift the arranged weight / weights. The weight / weight weighs several hundred tons and by lifting the positional energy can be stored. If necessary, the weight is drained off and the potential energy is generated which is converted into a generator and fed into the power grid.

This can be used in low wind chimney stored energy and the efficiency of the wind turbine (WKA) can be increased.

Embodiments of the invention are shown in FIG 1 to 5 shown.

1 Wind turbine after 1 with tower ( 3 ) on the foundation ( 1 ), with the nacelle ( 7 ), the rotor blades ( 8th ) the external weights ( 5 ) when they are in position above and the outside weights ( 6 ) when they are in position down the winches with motors ( 9 ), the brackets for the winches with motors ( 14 ), the traction cables ( 4 ) and with the generator ( 2 ). The weights ( 5 ) are replaced by guide rollers ( 11 ) in the guide rails ( 12 ) and can thereby also with towers, which increase down their outer diameter, are guided along.

2 In 2 is the tower ( 3 ) of the wind turbine after (1) shown in vertical section. You can see the tower ( 3 ) with the enclosure ( 10 ) over the pulleys ( 13 ) with the tension cables ( 4 ) two of several winches with motor ( 9 ) which are stored on consoles ( 14 ) which are installed at any height or on the ground.

3 3 is a horizontal section below the pulleys ( 13 ) where the segments of the weight ( 5 ) are recognizable. Depending on the design, the weights can be executed in two or more parts. After the number of weights then the number of winches with motor ( 9 ) certainly.

4 Here is the detail of the guide rails ( 12 ) at the tower ( 3 ) are recognized. The guide rollers ( 13 ) are attached to the weight and are guided in the guide rails.

5 differs from 1 in that the weights are mounted on the inside of the tower instead of on the outside of the tower.

It is also possible to use a combination with weights inside and outside. This possibility is only pointed out, but the situation is not shown graphically.

Wind turbine after 5 with tower ( 3 ) on the foundation ( 1 ), with the nacelle ( 7 ), the rotor blades ( 8th ) the inside weights ( 5 ) when they are in position above and the weights ( 6 ) when they are in position down the winches with motors ( 9 ), with the pulleys ( 13 ), the brackets for the winches with motors ( 14 ), the traction cables ( 4 ), with the generator ( 2 ).

The weights ( 5 ) are replaced by guide rollers ( 11 ) in the guide rails ( 12 ) and can thereby also with towers, which increase their inner diameter down, are guided along.
