- the second channel can be provided with shut-off devices on both sides. These shut-off devices can either reduce the flow cross-section or block it by one
- shut-off devices If one of the shut-off devices is at least partially closed, or if no water runs into or through the second channel, it is generally necessary to remove the rest of the partial flow. This takes place via the first channel, in the course of which an energy conversion device for generating energy is arranged. At least part of the partial flow is therefore used synergistically to generate energy. As a further synergetic effect, at least the flow that emerges from the first channel is used as a guide flow for the fish and for large-scale detection.
- first ones Computing arrangement In order to prevent floating material and, if necessary, debris from entering the first channel and thus the energy conversion device, there are first ones Computing arrangement and optionally a bed load threshold provided.
- This first rake arrangement covers the first channel in the headwater area in such a way that the partial flow can enter the first channel, but screenings are diverted.
- this derivation can take place in - and in particular through - the second channel, with which the second channel not only serves as a fish lock, but also for the derivation of screenings and preferably also attachments.
- This inclination also means that the fish are also directed from the rake towards the second channel.
- a computing arrangement can also be provided on the underwater side as a second computing arrangement. In this area too, the computing arrangement can be inclined in the direction of the second channel, so that a section converging in the direction of the second channel is formed.
- the speed difference between the leading flow and the water should be greater than about 0.3m / s, so that the leading flow has a speed which is at least 0.3m / s higher than the surrounding water in the underwater area.
- the energy conversion device can be designed as a hydropower plant, in particular as a turbine. Is preferred by the inclination
- Computing arrangement formed a converging section.
- the converging profile of this section is preferably in a horizontal plane.
- the section is thus narrowed sideways, towards the second channel.
- the outflow speed from the first channel is lower than from the second channel.
- the amount of water emerging from the second channel is smaller than that emerging from the first channel
- the water level can be lowered by actuating one or more shut-off elements, for example the inlet closure element, so that the screenings can be detached from the rake arrangement and removed.
- shut-off elements for example the inlet closure element
- Rake cleaning machine can be provided.
- the second arithmetic arrangement allows the outlet cross-sectional area to be enlarged and thus the outlet velocity of the water from the first channel in the
- the second computing arrangement can have larger rod spacings of the computing rods than the first computing arrangement, since the second
- Computing arrangement does not necessarily have the protective function for the fish or the
- a further computing arrangement in particular a fine rake, can be arranged just before or in the area directly after the energy conversion device.
- the bars of the rake of the second rake arrangement can cantilever freely at the rear end or can be designed without attachment in order to be able to remove the screenings better. Designs as rope rakes, louvers or the like are also possible.

- FIGS. 1 comprises a first computing arrangement 8, which is arranged in the upper water area 4 and serves as a computing arrangement for protecting the energy conversion device 6 or the first channel 3. This first
- Computing arrangement 8 is, as in this embodiment, opposite to the
- Flow direction 1 inclined In particular, the first computing arrangement 8 is inclined in such a way that a section converging along the flow direction 1 towards the second channel 7 is or will be formed.
- the screenings retained by the first rake arrangement 8 are, if appropriate, automatically conveyed in the direction of the second channel 7. The screenings can subsequently be removed through the second channel 7.
- an attachment threshold 12 is preferably provided.
- This bedlock threshold 12 is preferably arranged in the area of the base plate 10 and also preferably seals this area with the base plate 10 in such a way that the bedload along the bedlock threshold 12 is at least stopped, but is preferably also directed towards the second channel 7. As a result, the second channel 7 can also be used to remove the attachment.
- the shutoff element 13 on the upper water side can be closed.

- Energy conversion device 6 provided a rake in this

- shut-off device 13 on the underwater side can then be closed, with which the fish in the second channel 7 temporarily
- shut-off device 13 can be opened, which in turn
- shut-off device 13 on the upper water side can then be closed and the shut-off device 13 on the underwater side can be opened. That part of the partial flow 2 that does not flow through the second channel 7 is conducted into the first channel 3 and used there for energy generation.
- a cleaning mode can be started after a certain time.
- Cleaning mode open the two shut-off devices 13 of the second channel 7, with which water from the headwater area 4 is passed through the second channel 7 relatively quickly and the bed load and / or screenings are discharged through the second channel 7.
