Description

DESCRIPTION

Hydroelectric power station

A hydroelectric power station is a well-known type of power plant where the kinetic energy of the water is converted into mechanical energy and subsequently into electrical energy. In this regard, known power plant type u. a. Tidal power plants, which in particular uses the Tidenhub, ocean current power plants, which uses the kinetic energy of ocean currents, or wave power plant, which, unlike a tidal power plant, not the Tidenhub, but exploits the energy of the continuous ocean waves themselves.

Hydropower plants are used in hydroelectric power plants, which convert the potential and / or kinetic energy stored in the water into electrical work.

In particular, the potential energy of water, in particular dammed up, is used

Flowing water, such as streams, rivers, streams, the kinetic energy (kinetic energy) of the water of streams and the kinetic energy of the tides, which caused by the gravity of the moon, the sea water rise and fall.

Among the hydroelectric engines include u. a. the water turbine and the waterwheel.

A water turbine converts the kinetic energy of water into mechanical energy. This resulting rotational movement is used, for example, to drive a generator which serves to generate electric power.

CONFIRMATION COPY A water wheel is rotated by water power, thereby the potential and kinetic energy of the water is used, for example, to drive a generator from a hydroelectric power plant.

Hydroelectric power plants, which can be used both in the area of the Exclusive Economic Zone (EEZ), the continental shelf, on the high seas, in running waters or from confluence of waters into the sea with relatively little technical effort and low costs, are not known. In the aforementioned areas are different types of flow of ocean currents, such as sea waves, Tidenhub, buoyancy, salinity or thermohalinity found. In addition, there are different air currents, such as Euler wind, geostrophic wind,

Gradients wind and cyclostrphical winds, and mixtures of water and air (spray) can be found. Hydroelectric power plants which use different types of flow of the ocean current and at least partially different air currents for the generation of electric power are not known.

Hydroelectric power plants for only some of the o. G. Areas are known, but technically very complex and have not been able to prevail in practice, although there is a high demand in this regard for a long time.

The object of the invention is to provide a hydroelectric power plant, which overcomes the disadvantages of the prior art, has a technically simple structure and is universally applicable.

In addition, the energy yield per location of a conventional

Wind turbine located in the Exclusive Economic Zone (EEZ), the continental shelf, on the high seas, in flowing waters or estuaries of

Waters into the sea is planned or already exists to be increased.

The object of the invention is achieved by a hydroelectric power plant with the features according to claim 1. It is essential to the invention that at least one water turbine is arranged horizontally on the mast, wherein this water turbine at least comprises: an electric generator and blade body and a wind turbine is arranged on the mast.

This basically allows:

• Use in water in the different types of flow

Ocean currents (outflows into the sea, buoyancy, salinity, thermohalinity, tidal flow,)

• Use in the air (in different air currents such as Euler wind, geostrophic wind, gradient wind, cyclostrophic winds and

• Use in the mixtures of water and air (waves and

Wave mixtures with air).

The generation of electric current is based on the fact that the attachment to the ground is particularly mass-rich.

The use of the invention can take place in the zones:

It is also possible, the hydroelectric power plant according to the invention in existing wind turbines, for example by attachment to the shaft of

Wind turbines, nachzurösten or integrate and thus a larger

to achieve energetic performance per site. This combination of use of wind and current is very effective and very ecological.

An advantage is that in the planning of wind turbines, the energy yield per site is significantly increased by the combination of the wind turbine with the hydroelectric power plant according to the invention, the investment costs only increase disproportionately.

The dependent claims 2 to 13 give further advantageous embodiments of the invention according to claim 1 again, without limiting these.

It is preferred that the foundation is one of the foundation types: Monopile, Jacket, Tripod, Tripile, Gravity Foundation, Bucket Foundation, or Floating Foundation.

It is preferred that at least a pair of two water turbines is arranged on the mast, wherein these are arranged one above the other, separate from one another and the blades of the blade body of the first water turbine in a direction of rotation and the blades of the blade body of the second water turbine in a counter-rotating

Turn direction

By opposite rotational movement of the two blade body, d. H. right-turning and left-turning, the lifting of forces is realized in the simplest way, otherwise to instabilities, for example, in the case where both would be right-turning.

It is preferred that the blade body consists of at least two segments which are detachably connected to each other. This allows a modular design, so that the individual segments can be cost-effectively floated and mounted on site. By virtue of the fact that these segments are capable of being ligated, they can be positioned precisely, in particular with an exact height, by trimming, ie corresponding filling or evacuation of the water. Due to the modular structure, several individual parts are available as in a pie slice. These should not exceed the dimension so that the individual modules or segments can be transported easily and inexpensively.

To transport a suitable measure of production well with a normal pusher boat. No custom-made special ships necessary, as often necessary in wind turbines.

It is preferred that the segments each have a legible base body. This makes it possible in a simple manner trimming by using bilge pumps of the respective blade body and a height adjustment. In addition, this opens up the possibility of obtaining buoyancy of the blade body in certain desired operating states.

It is preferred that the blade body is arranged perpendicular to the center line of the mast and the mast is guided centrally through the blade body. For a structurally simple way a stable construction is realized.

It is preferred that at least the uppermost blade body can be acted upon by the ocean current, swell and / or wind.

Thus, the hydroelectric power plants according to the invention can use different flow types of the ocean current and at least partially different air flows for the generation of electric current.

It is preferred that a photovoltaic system and / or a platform is or are arranged on the mast.

By means of this design solution, further functionalities can be made possible in a simple manner and with relatively little technical effort.

The waves absorb the energy of the water and thus transfer the energy of the air flow to that of the water (energy conservation law). The thus transferred energy of the water can thus be absorbed by the hydropower plants. Thus, the entire energy of the water surface, which is located around the area of wind turbines, can be energetically exploited.

Thus, in addition to the flow energies, the converted energy of the air flow can be converted into electricity.

The additional attachment of a photovoltaic system also allows the effective use of solar energy for electric power generation.

It is preferred that the electric generator is arranged in the blade body.

The arrangement of the generators on the mast has an advantageous effect on the statics, since by the mass distribution and thus focus down center of gravity results in an advantageous result.

Due to the arrangement of the generators on the mast, the flow energy (Kolkung), which kills the foundations from the bottom of the foundations is reduced or completely

added. There are no or lower costs for the repair (repair).

The object of the invention is also achieved in each case by the features of claims 14 and 15.
