Fig. 1 and Fig. 2 show schematically an exemplary embodiment of the power plant of the invention, which has a storage device 1, which is installed in a river 2 or river with slope.

The storage device 1 has a first barrage 1.1 and a second barrage 1.2, which is angordnet downstream with distance to the first barrage 1.1. The first barrage 1.1 has a foundation 1.11, which is installed in the bottom 3 of the river 2, and a vertical dam wall 1.12, which dammed the river water. Likewise, the second barrage 1.2 has a foundation 1.21, which in turn is built into the bottom 3 of the river 2, and a vertical dam wall 1.22, which dammed again the river water. The two stowage walls 1.12 and 1.22 are each constructed as a continuous cross-construction in the riverbed 2.1. Between the two barrages thus a storage chamber 8 is formed for the river water. The entire storage device 1 is made of reinforced concrete.

The baffle wall 1.12 of the barrage 1.1 has a passage 4 with a rectangular cross-section at the level of the bottom 3 of the flow 2. In the passage 4 is a rotary device 5 with an integrated electric generator housed as a generator.

According to EP 2191129 Bl, the rotary device 5, in order to gain energy from the flow movement of the flow 2 with increased Strö ^¬ mungsgeschwindigkeit within the passage 4, a main rotator, which is fixedly connected to a central axis of rotation of the rotary device, and one or more rotational surfaces which are rotatably mounted on the main rotator about their axes of rotation spaced from the central axis of rotation such that the main rotator can rotate about the central axis of rotation through the one or more rotational surfaces, the axes of rotation being parallel to the axis of the main body extend. Further, the rotary device has a shuttle or control means for controlling or adjusting the position of the rotating surface or rotating surfaces relative to a flow direction of the river or water body having an adjusting sleeve and / or an adjusting frame for each rotating surface, wherein the adjusting sleeve or the adjusting frame about the central axis of rotation is freely rotatably disposed about, but is not rigidly or frictionally connected to the central axis of rotation radially, and is coupled to the associated surface of rotation to transmit their pendulum motion on the surface of rotation for adjusting the rotational surface. The main axis of the rotary device is fixedly coupled to an electrical generator for generating electrical current.

Assuming the undisturbed river 2 has a water cross-sectional area of A = 5m ² and a flow velocity vi = 1 m / sec, the volume flow of the river water is vi x A = 5 m ³ / sec. By increasing the damming height of the river 2 by means of the barrage 1.1 of the storage device 1 of the invention, however, the flow rate of the water in the passage 4 is increased, namely to a value v2 = about 4 m / sec. The estimated electric power P of the first barrage 1.1 of the power plant then results in a cross section of the passage 4 of about 1.25 m ² to P = 37.5 kW. If the second storage stage ^¬ arranged 1.2 so far from the first storage step 1.1, that again ungestauter flow rate of 5 m ³ / sec results due to the flux gap, can by means of the second storage stage 1.2, and of the power generator of rotary device 7 and the generator within the passage 6 more P = 37.5 kW to be generated. With the power plant of Fig. 1 and 2, thus, a total electrical power of P = 75 kW can be generated.

Figures 3 and 4 show schematically another exemplary embodiment of the power plant of the invention having a stowage device 10 installed in a flow 2 and occupying only part of the cross section of the riverbed.

The storage device 10 is constructed as a dry pool 10.1 with a total of five juxtaposed chambers 15.1, 15.2, 15.3, 15.4 and 15.5, by a continuous side wall 11, a further parallel thereto side wall 11.1 and a total of six transverse walls 12.1, 12.2, 12.3, 12.4, 12.5 and 12.6 are formed, which are arranged one behind the other, parallel and at a distance from each other. The transverse walls 12.1 to 12.6 are perpendicular to the floor 13 and contain except for the transverse wall 12.6 at the end of each passage 14.1, 14.2, 14.3, 14.4 and 14.5. The last transverse wall 12.6 is thus a barrier wall.

In the passages 14.1 to 14.5, respectively, a rotary device 15 or turbine with generator for generating electrical power is housed. At least the passage 14.1 is provided with a closure 16, for example a slide, in order to close or block the passage 14.1, which is fluidically connected to the flow 2. In alternative, each of the passages 14.1 to 14.5 could also be equipped with a nem closure 16 may be provided. The passageway 14.1 is located at a level, for example, 1 m below the Wasseroberf ^¬ Smile Friend. The passage 14.2 is then provided at a level of 2 m below the water surface 2.3, while the passage 14.3 and the passage 14.4 is at a level of 3 m and 4 m below the water surface 2.3. Finally be ^¬ there is the passage 14.5 at the level of the bottom 13, or about 5 m below the water surface 2.3.

In Fig. 4, the state of the dry pool 10.1 of the power plant is shown when the entire drying basin 10.1 so the chambers 15.1 to 15.5 'filled with water from the river 2 or waters and thus has been generated via the rotary devices 15 with generators maximum electrical energy , In this case, the shutter 16 is opened.

If the drying basin 10.1 is filled, the passage 14.1 is blocked by the closure 16 and, if there is an excess of electricity, the drying basin 10.1 can be empty by means of an electric pump which is fluidically coupled to the last chamber 15.5 of the drying basin via corresponding lines be pumped, the pumped water is simply fed back to the river 2. Consequently, in contrast to conventional pumped storage power plants, in which, as is known, the dry pool is filled in surplus power, in the invention, the dry pool 10.1 is pumped empty in excess of electricity. The electric power for supplying the pump is provided by a secondary power plant, such as a wind power plant or a water wheel, in surplus power, which may be constructed, for example, as said rotary device with a coupled generator. When electricity is required, the shutter 16 can then be opened again in order to supply electrical energy in the rotary devices 17 with coupled generators. through the water flowing into the drying basin 10.1 until the drying basin 10.1 is filled again.

Fig. 5 and Fig. 6 schematically show yet another game-like wherein ^¬ embodiment of the power plant of the invention, which has a storage device 20 which is installed in a flow 2 and occupies only a portion of the cross section of the river bed. Here is the storage device 20 as a displacement channel

26 constructed and has a base 23 at the bottom of the river 2 with the water level 2.3, a vertical transverse wall 22 at which the water jams, and parallel side walls 25 and

27 on. In the transverse wall 22, a passage 24 is provided, in which a rotary device 21 is housed with an electric generator. Also by this stowage device 20, the flow velocity of the water is increased in the passage 24, whereby a higher current efficiency is made possible. The passage 24 is located, for example, 1 m below the upcoming water surface 2.3. An outlet 28 of the displacement channel is preferably removed from the rotary device 21 or turbine so far that a water gradient of 1 m is achieved.

Fig. 7 and Fig. 8 schematically show another exemplary embodiment of the power plant of the invention having a stowage device 1 installed in a river 2 or a river with a slope.

The storage device 1 has a first barrage 1.1 and a second barrage 1.2, which is spaced downstream of the first barrage 1.1. The first barrage 1.1 has a foundation 1.11, which is installed in the bottom 3 of the river 2, and a vertical dam wall 1.12, which dammed the river water. Similarly, the second barrage 1.2 has a foundation 1.21, which in turn is built into the bottom 3 of the river 2, and a vertical retaining wall 1.22, which dammed up the river water again. The two stowage walls 1.12 and 1.22 are each constructed as a continuous cross-construction in the riverbed 2.1. Between the two barrages thus a storage chamber 8 is formed for the river water. The entire storage device 1 is made of reinforced concrete.

The baffle wall 1.12 of the barrage 1.1 has a passage 4 with a rectangular cross section at the level of the bottom 3 of the river 2. In the passage 4, a rotary device 5 is housed with an integrated electric generator as a power generator.

As shown schematically in Fig. 7 only by the double arrow shown, the passage 4 can be vertically adjustable in height. Consequently, a stationary, relatively large opening may be provided in the stowage wall 1.1 and a slide may be provided which is arranged in or at the opening in which the passage is formed and which is vertically movable so that a vertical movement of the slide Adjusted height of the passage 4 on the storage device, wherein the slide covers the opening of the retaining wall 1.1 in any vertical position. Furthermore, at the bottom of the stowage device 1 may be provided a vertical countersink, which is recessed in the ground and in which the slider can engage or retracts when it is moved vertically.

According to EP 2191129 B1, in order to be able to obtain energy from the flow movement of the flow 2 with increased flow velocity within the passage 4, the rotary device 5 can have a main turning device fixedly connected to a central rotation axis of the rotation device and one or more turning surfaces are mounted rotatably about their axes of rotation at a distance from the central axis of rotation on the main revolving device such that the main revolving elements Device can perform a rotational movement about the central axis of rotation by a rotating surface or by a plurality of rotating ^¬ surfaces, wherein the rotational surface axes extend parallel to the axis of the main body. Furthermore, the Rotationsvor ^¬ direction has a pendulum device or control device for controlling or adjusting the position of the rotating surface or rotating ^¬ surfaces relative to a flow direction of the river or body of water, which has an adjusting sleeve and / or an adjusting frame for each surface of rotation, wherein the adjusting sleeve or the adjusting frame is freely rotatably disposed about the central axis of rotation, but is not connected rigidly or frictionally with the central axis of rotation radially, and is coupled to the associated rotary surface to transmit their pendulum motion on the rotational surface for adjusting the rotational surface. The main axis of the rotary device is fixedly coupled to an electrical generator for generating electrical current.

Figures 9 and 10 schematically show another exemplary embodiment of the power plant of the invention having a stowage device 10 installed in a flow 2 and occupying only part of the cross section of the riverbed.

In the passages 14.1 to 14.5 is in each case a rotary device 15 or turbine with generator for generating Electricity housed. At least the passage 14.1 is provided with a closure 16, for example a gate valve, in order to be able to close off or block the passage 14.1, which is connected to the flow 2 by the fluid. In ^alternative , each of the passages 14.1 to 14.5 could also be provided with a closure 16. The passage 14.1 is at a level, for example, 1 m below the water surface. The passage 14.2 is then provided at a level of 2 m below the water surface 2.3, while the passage 14.3 and the passage 14.4 is at a level of 3 m and 4 m below the water surface 2.3. Finally, the passage 14.5 is at the level of the bottom 13 or about 5 m below the water surface 2.3.

As shown schematically in FIG. 9 only by the double arrows shown, each or only part of the passages 14.1 to 14.5 can be set vertically adjustable in height. Consequently, in each case a relatively large opening can be provided in the transverse walls and there can be one slide per transverse wall arranged in or at the associated opening, in which the corresponding passage is formed and which is vertically movable such that a vertical Movement of the slider adjusts the height of the passage on the transverse wall, wherein the slider covers the opening of the transverse wall in each vertical position. Furthermore, in each case a vertical countersink can be provided at the bottom of the respective transverse wall into which the associated slide can engage during adjustment.

In Fig. 10, the state of the dry pool 10.1 of the power plant is shown when the entire drying basin 10.1 so the chambers 15.1 to 15.5 is filled with water from the river 2 or waters and thus on the rotary devices 15 with Generators maximum electrical energy has been generated. In this case, the shutter 16 is opened.

If the drying basin 10.1 is filled, the passage 14.1 is blocked by the closure 16 and, if there is an excess of electricity, the drying basin 10.1 can be empty by means of an electric pump which is fluidically coupled to the last chamber 15.5 of the drying basin via corresponding lines be pumped, the pumped water is simply fed back to the river 2. Consequently, in contrast to conventional pumped storage power plants, in which, as is known, the drying basin is filled with surplus of electricity, in the invention the drying basin 10.1 is pumped empty when there is an excess of electricity. The electrical power to power the pump is supplied by a secondary power plant, e.g. a wind power plant or a water wheel, provided with excess current, the e.g. can also be constructed as said rotary device with coupled generator. When power is required, the shutter 16 can then be reopened to generate electrical energy in the rotary devices 17 with coupled generator through the water flowing into the dry pool 10.1 until the dry pool 10.1 is refilled.

Figures 11 and 12 schematically show yet another exemplary embodiment of the power plant of the invention having a stowage device 20 installed in a flow 2 and occupying only part of the cross section of the riverbed. Here is the storage device 20 as a displacement channel

27 on. In the transverse wall 22, a passage 24 is provided, in which a rotary device 21 is housed with an electric generator. Also by this stowage device 20, the flow rate of the water is increased in the passage 24, whereby a higher current efficiency is made possible. The transit passage 24 is located, for example, 1 m below the pending ^¬ the water surface 2.3. An outlet 28 of the Verdrängungska ^¬ Nals is ^¬ Trains t of the rotation device 21 or turbine prior to such an extent that a water drop of 1 m is obtained.

As shown schematically in FIG. 11 only by the double arrow shown, the passage 24 can be vertically adjustable in height. In the transverse wall 22 a stationä ^¬ re, continuous, relatively large opening can thus be provided and a slider may be provided, which is arranged in or on the opening, in which the passage is formed and which is vertically movable such that a vertical Movement of the slider, the height of the passage 24 is adjusted to the storage device 20, wherein the slider covers the opening of the transverse wall 22 in each vertical position. The passage 24 has compared to the opening only a relatively small clear cross-section or corresponds to only a portion of the opening in the transverse wall. Furthermore, a vertical countersink can be provided at the bottom of the storage device 1, in which the slider can engage during adjustment.

Figures 13 and 14 are schematic views of another embodiment of the invention having a stowage device 90 having a reservoir 96 and a height-adjustable passage 92 which here serves as an outlet for the water 94 from the reservoir 96 or pumping basin into the water 95 e.g. a river serves.

The reservoir 96 has vertical basin walls 102 and is located on the shore 101 of the body 95. In one of the basin walls 102, a continuous and relatively large opening 100 is excluded (indicated by dash-dotted lines in FIG a bottom 103 of the reservoir 96 up to an upper edge 104 of the pool wall 102 or the reservoir 96 vertically he ^¬ stretches and has a rectangular cross-section. A senkrech ^¬ ter-lowering shaft 98 with an associated shaft wall 97 extends from concrete from the bottom 103, starting downward in the extension region of the opening 100. In the opening 100 and the shaft 98 is housed a plate-shaped or wall-shaped slide ^¬ about 93 and vertically movably guided, the dimension fits into the opening 100 of the reservoir 96 and into the well 98. The passage 92 is recessed in the slider 93 so that water 94 from the reservoir 96 through the opening 100 and the passage 92 and therefore flow or by the housed therein turbine in the body of water 95 flow away ^¬ SEN, in order to generate electric power.

As can be seen in FIG. 13, the slide 93 with the passage 92 is in a vertical position which is relatively high up, the slide with its upper end 91 already protruding beyond the edge 104 of the reservoir 96, but still into the Shaft 98 engages with its lower end 105. The passage 92 with turbine is thereby below a level 99 of the water 94 in the reservoir 96, but still above a level 95.1 of the water body 95, so that water from the reservoir 96 can flow through the passage 92 with turbine into the water to be able to exploit the gap between the water 94 in the reservoir 102 and the water body 95 for electrical energy production.

Decreases the level 99 in the reservoir 96, the slide 93 is moved with the Duchlass 92 starting from the altitude in Fig. 13 vertically downwards in the Senkschacht 98 accordingly, adjusted or tracked, he reached the altitude, shown in Fig. 14 is. At this altitude, the end 91 of the slider 93 is flush with the edge 104 of the reservoir 96 and the lower end 105 of the slider 93 extends further into the Senkschacht 98 into it. Since a Ge ^¬ falls is also in this position between the levels 99 and 95.1, can flow into the passage 92 by the water turbine (106) to generate electricity.

An electromotive drive can be provided, which is coupled to the slider 93 in order to effect its vertical height adjustment. Furthermore, a Verstellsteuereinrichtung for controlling the electric motor drive and / or the slider 93 depending on the level 99 in the reservoir 96 may be coupled to the electric motor drive. The adjustment control device may in turn have a level detector for detecting the level 99, wherein the level detector is provided for example with a float which floats on the water surface of the water 94 in the reservoir 96 and moves with the level 99. The movement of the float can be converted, for example, into an electrical signal, which in turn is fed to the input control of a program-controlled microprocessor of the adjustment control device by polling. The microprocessor evaluates the electrical signal and controls the electric motor drive in such a way that the slider 93 is tracked to the level 99. The electromotive drive can e.g. an electric motor, which is coupled to a gear, which in turn engages in a rack, which is connected to the slider 93. The movement of the electric motor is then converted via the gear and the rack into a corresponding vertical movement of the slider 93 and thus also of the passage 92.
