Description

The invention relates to a hydropower plant, the Use of very high energy potential of water in the Should enable high mountains.

Dams have largely been known and proven and pumped storage plants in the high mountains and z. T. on average mountains prevailed. There are drops of several here hundreds of meters, in some cases several thousand Meters reached. Pumped storage plants under of auxiliary energy are also known, but have not yet made it through can put.

The problem with the dams is that the water a considerable amount due to the inflow into a reservoir Loses some of its potential energy as this spokes mostly have to be created in valley locations.

So far, the possibility of the water in the high mountains at the highest possible place of the beginning to drain and energetically to use.

The object of this invention is a hydropower plant to describe the bill of this aforementioned claim wearing. The hydropower plant developed from this can because of a more or less abundant water supply or primarily when using limited storage spaces used as a short storage system to cover peak loads will.  

This restriction will then lapse if greater water supply and storage offer opportunities.

The object is achieved in that one or more related underground (1,25) Storage rooms in a mountain or several mountains be installed.

Below are explanations of each of the Energy generation with reference to the corresponding Given drawings (sketches). It shows

Fig. 1
A high pressure hydropower plant is shown. The height differences between the machine house ( 6, 7 ) and the storage chamber ( 1 ) should be between 1000 and 2000 m.

The underground high storage chamber ( 1 ) is to be designed accordingly in accordance with the intended storage volume in several interconnected, level storage spaces.

The rainwater, spring water, brook water, melt water and glacier runoffs are conducted into the high-volume storage space ( 1 ) via surface-mounted manifold systems ( 4 ), ring manifolds ( 3 ) and connecting pipes ( 2 ). From here the force descent takes place via a pressure shaft ( 5 ), water shaft ( 10 ), turbine ( 6 ), generator ( 7 ), drain line ( 8 ) to the lower storage tank ( 9 ).

The volume of the underground high storage rooms ( 1 ) must always be assessed depending on the water supply, the electrical output to be achieved, geological and ecological considerations.

This general definition also applies to everyone variants described below.

Fig. 2
The ultra-high pressure hydropower plant with pump storage is characterized in that the water collects the precipitation, spring, stream, melt water and glacier drains in the upper storage area ( 1 ) via surface collecting pipes ( 4 ), ring collecting pipes ( 3 ) and connecting pipes ( 2 ) after the decrease in power via downpipes or pressure shafts ( 5 ) and generation of electrical energy in the turbine / generator ( 6, 7 ) in the lower, underground storage space ( 25 ) is caught. In low-load night times, it is conveyed by means of one or more pumps ( 16 ) via the suction ( 12 ) and pressure line or pressure shafts ( 13 ) into the upper, un-underground storage space ( 1 ).

The water lock ( 10 ) serves to dampen the pressure surges.

Fig. 3
In order to cover a larger water catchment area, one can arrange several underground high storage basins in different mountain ranges and / or one chooses the storage option described below with cascade-like storage rooms.

The underground high storage rooms are in different whose heights are arranged in a cascade-like manner.

The water is supplied to the storage spaces ( 1 ) via surface collecting systems ( 4 ), ring lines ( 3 ), connecting lines ( 2 ). The water reaches the turbine ( 6 ) and generator ( 7 ) via downpipes or pressure shafts ( 5 ).

The pressure shafts ( 5 ) connect the individual storage spaces in such a way that each storage space can be used separately for energy purposes ( Fig. 3a). After the energy has been generated in the generator ( 7 ), the water either flows into a lower storage basin ( 9 ) or into an underground storage space ( 25 ) from which it is drawn through suction lines ( 12 ) via pumps ( 14 ) and associated pressure lines / pressure shafts arranged at the appropriate altitude ( 13 ) is pumped back into the individual high storage rooms ( 1 ). This is done with inexpensive nighttime electricity.

Fig. 3a
The individual underground high storage rooms ( 1 ) are connected to the pressure shaft ( 5 ) by separate branch lines / shafts, which are to be shut off by slides ( 17 ).

Fig. 4
The surface collecting lines ( 4 ) are laid directly below the surface of the earth and represent the actual water collection systems. These surface collecting lines conduct the water via connecting lines ( 18 ), ring collecting lines ( 3 ) to the storage spaces via connecting lines ( 2 ). Flowing surface water as well as natural flowing water ( 26 ) can be used for water storage.

Fig. 5
This illustration shows the arrangement of the individual pipe systems in vertical section.

Fig. 6a
The surface collecting lines ( 4 ) are arranged in trenches ( 19 ). Coarse-grained rock gravel ( 20 ) is located above it, which is separated from the collecting pipe by expanded metal sieves or perforated plates ( 21 ). This arrangement has several functions. On the one hand, the rock pebble is used to adapt to the surrounding terrain in accordance with the local rock formation. On the other hand, this training has protective functions against pollution and frost effects.

Fig. 6b
The collecting tube is provided as a single tube with suitable perforations (opening cross-sections). A double pipe arrangement is also possible in which two pipes ( 22, 23 ) pushed into one another and equipped with opening cross sections can close or release the entry cross section by twisting or moving (drives required).

This type of collection of surface water is particularly suitable in water-endangered zones (torrents, Muren) as well as in the area of glaciers and Snow fields.

When water is drawn from streaming fluid beds, it is recommended the installation of a local sampling valve.

Fig. 7
The arrangement of the rock pebble above the collecting pipe ( 4 ) is also possible in a removable cassette ( 24 ) with floor openings in order to enable cleaning of the rock pebble better.
