Definitions
- This invention relates to an apparatus for generating energy from flowing water, in particular to a hydroelectric installation of comparatively modest size.
- Hydropower plants are for instance known for the drive of machinery in the form of watermills and for generating electric energy with the aid of artificially constructed reservoirs. This latter form is
- the invention provides an apparatus for generating energy from flowing water, as defined in one or more of the appended claims. More particularly, the apparatus according to the invention comprises a paddle wheel rotatable around a horizontally disposed shaft, with a plurality of paddles arranged along an outer circumference of the paddle wheel, channeling means for channeling a water stream in a range of the paddle wheel that is located under the horizontally disposed shaft, a generator for electric energy, driven by the paddle wheel, and setting means for automatically setting a position taken up by the waterwheel relative to a water surface of the water stream.
- an interaction taking place between the water stream and individual paddles of the plurality of paddles arranged along the outer circumference of the paddle wheel is optimized.
- the automatic setting of an optimum position taken up by the paddle wheel relative to a water surface is especially important with locally placed, comparatively small-scale energy-generating devices which would otherwise be difficult to observe and monitor.
- the generator driven by the paddle wheel is preferably a permanent magnet generator.
- the generator to be driven by the paddle wheel can have a shaft drive with a right-angle transmission, and in other cases a toothed-belt drive. In the latter case, a low-speed permanent magnet generator is preferred.
- the setting means may be expanded to include an intelligent data system.
- the paddle wheel may have a core drum, whose centerline coincides with the horizontal shaft.
- the core drum may then be provided at each of its opposite axial ends with a side or end flange, extending radially from an outer
- the paddle wheel rotatable around the horizontal shaft may, in the invention, also comprise a plurality of individually movable paddles. These individual paddles may then each be movable between a passive tangential position, in which it can pass in a water stream with minimal resistance, and an active radial position, in which it can be optimally driven by a water stream.
- each individually movable paddle is pivotable about a paddle pivot extending parallel to the horizontal shaft and can then be pivotable about a paddle pivot situated at the outer circumference of the core drum.
- each paddle pivot extending parallel to the horizontal shaft can comprise a pivot arranged between two opposite end flanges of a core drum.
- each paddle from its passive tangential position to its active radial position may be limited by a projecting stop, in which case each individually movable paddle in its active position can abut by an outwardly facing side thereof against the stop.
- the stops may be positioned in circumferential direction of the paddle wheel between two successive pivots and may also serve as stops for the passive position in that an inwardly facing side of each paddle comes to a stop against a stop trailing in circumferential direction. If desired, it is also possible to have the movable paddles in their passive position abut, overlapping by their inner side, against an outer side of a trailing adjacent paddle.
- Each paddle may further comprise a convexly shaped outer side and a convexly shaped inner side. In the active position a respective paddle receives water in the concavely shaped inner side.
- the automatic setting means for optimally setting a position to be taken up by the paddle wheel can make use of parameters selected from a group comprising: water supply, water flow rate, water height, speed of the paddle wheel, position of the paddle wheel, energy requirement, electric tension, as well as signals of limit switches and charging current control devices.
- the automatic setting means may then be configured for, starting from measurements, by software, giving a command to set the waterwheel at a different height position relative to the water surface.
- the automatic setting means may then also comprise at least a communication module and/or a monitoring module, at least one of which is configured for, at a low electric tension, limiting the power consumption by partly switching off the automatic setting means.
- the automatic setting means may comprise a monitoring module which is configured for, in a predetermined time interval, activating a PLC unit and a communication module of the automatic setting means to carry out measurements and to process obtained measuring data to optimize, or keep optimal, the position taken up by the paddle wheel relative to the water surface.
- the monitoring module may then be configured for continuously measuring a water level upstream of the paddle wheel, so that when a pre-set limit is exceeded within the
- a camera registration may be part of the automatic setting means.
- the apparatus is part of a weir with a fall in height between an inlet water surface at an upstream side and an outlet water surface at a downstream side.
- This weir is arranged for water management of a polder, and the channeling means are then advantageously implemented as a movable water guide on the upstream side.
- the setting means for optimizing then preferably comprise at least a single carrying arm which carries the horizontally disposed shaft and which extends from a fixed pivoting point at the downstream side up to a height-adjustable slide at the upstream side.
- the at least single arm is then movable up and down about the fixed pivoting point, together with the horizontally disposed shaft, along with the height-adjustable slide, and the movable water guide with the carrying arm.
- the means with which a position taken up by the waterwheel relative to a water surface of a water stream is automatically set comprise a water level tube, which can deliver a signal for operation of a spindle slide motor.
- the water guide implemented as a fish/water slideway is connected with the height-adjustable shde implemented as a spindle slide.
- the spindle shde is driven by an electronic spindle slide motor.
- the water level tube delivers a signal so that the spindle slide motor moves the shde up and down to the desired liquid height set.
- a command can be given to the spindle motor to set the waterwheel at a different height position relative to the water surface, by having the spindle or spindles turn clockwise or anticlockwise.
- the height-adjustable slide can then set a fall in height between the inlet water surface and the outlet water surface of between 20cm and 200cm.
- Such a polder weir may further comprise a technical space, which is arranged underground.
- the technical space then serves for
- measures may have been taken for protecting the water population.
- measures for protecting the water population can comprise a grid placed on the upstream side.
- the measures for protecting the water population can also comprise a fish-friendly water guide and a fish-friendly paddle shape for the individual paddles.
- a fish-friendly water guide and a fish-friendly paddle wheel are obtained in that in the polder weir the water guideway implemented as a fish/water shdeway, as it were, lays each fish in a water tray formed by the paddle and lets it go down with its own water. Thus, the fish does not fall down and cannot become jammed by the paddle. Also, the paddle wheel mostly turns at a sufficiently low speed.
- the apparatus according to the invention can also be part of a hydroelectric plant placed off the fairway in the surface water along the bank of a river.
- the channeling means are then formed by at least a single (buoyancy) float, and the setting means for optimizing then comprise at least a single ballast tank and a pump which is arranged in the at least single float and is in fluid communication with the surface water and that ballast tank.
- the hydroelectric plant is then anchored to a river groyne in a manner so as to be movable up and down.
- the part of the at least single float remote from the groyne may then be guided in a vertical direction along a pole anchored in the river bed, to which pole also a beacon for navigation may be mounted.
- the horizontally disposed shaft of the paddle wheel may be bearing-mounted to the at least single float.
- the paddle wheel may also be arranged between the at least single float and a second float.
- This first and second float may then be connected with each other, so that also the second float can be part of the channeling means.
- the number of pumps that is needed or that is used per float of this river unit for filling or emptying two ballast tanks per float may in each case be at least a single pump per float and per ballast tank. In total, there are preferably two pumps and four ballast tanks. For each float, this is preferably a (liquid level control) float pump. Per float there are preferably two ballast tanks in order that in the event of collision damage or of leakage, there is less chance of sinking.
- ballast tanks per float can be set more accurately and are more stable in case of wash.
- the second float may then also comprise at least a single ballast tank which is part of the setting means, but preferably also has two ballast tanks.
- this river unit also, an automatic setting of a position taken up by the
- waterwheel or paddle wheel relative to the water surface can be obtained by automatic control of the pump. Starting from measurements and by means of software, here too, a command can be given to the ballast pump system to set the waterwheel at a different height position relative to the water surface by means of the floats.
- a part of the circumference of the paddle wheel that is located above the horizontally disposed shaft may be covered with a protective hood.
- a trash or dirt guide may be arranged at least upstream of the paddle wheel at the inlet side.
- dirt guide may also be arranged on the outlet side (downstream), because many rivers have ebb and flow and so have two flow directions.
- a grid floor extending in a horizontal plane above the floats may be arranged.
- Generating energy may further, in the polder weir according to the invention, be combined with the carrying out of measurements, as of precipitation, flow rate, soil hydrology, and electric tension present.
- the waterwheel turns in the flow direction, around a horizontally disposed shaft.
- the (liquid level control) float system of the river variant arranges that if a floating obstacle is signaled, the wheel comes clear of the water by virtue of this system.
- the wheel with this float system besides serving for energy production, can also serve to retain water in a river or to discharge additional water if desired, the settability of this measure may be automated.
- the river variant can be sustainably utilized for flexible water level management.
- Measurements that can be used for the automatic height adjustment can comprise parameters such as: water supply (liquid flow), water height, speed of the waterwheel, energy requirement, and/or electric tension. It is also important that principal components of the apparatus, such as paddle wheel and water guides, can be made from recycled plastic.
- An automatically height-adjustable waterwheel which can also be lifted completely out of the water in the case of obstacles and/or a large water afflux that must not be impeded.
- An ecological paddle shape can be used.

- a polder weir hydroelectric plant 1 which comprises an apparatus for generating energy from flowing water.
- the apparatus comprises a waterwheel or paddle wheel 3, which is set up rotatably for rotation around a horizontally extending shaft 5.
- channeling means for channeling a water stream along the circumference of the paddle wheel 3 is here implemented as a movable water guide 9.
- the horizontal shaft 5 is bearing-mounted on a carrying arm 11 which on the downstream side is pivotable about a pivot 13.
- the non-visible opposite end of the horizontal shaft 5 is likewise bearing- mounted to this identical carrying arm.
- the water guide 9 and the end of the carrying arm 11 at the upstream side are mounted to a height- adjustable slide 15, as shown in Figure 2.
- This height-adjustable slide is driven by a spindle motor 17 so as to be adjustable in height, and as the slide 15 moves up and down, the carrying arm 11 and the water guide 9 move up and down concurrently with the slide.
- the carrying arm 11 then pivots about the pivot 13 and thereby moves the horizontal shaft 5 with the paddle wheel 3 up and down, simultaneously with the water guide 9.
- the water guide 9 preferably extends to over the slide 15.
- an inlet water surface 19 at the upstream side of the polder weir hydroelectric plant 1 is higher than a water surface 21 at the outlet side.
- a fall in height between the inlet water surface 19 and the outlet water surface 21 can be set by the height-adjustable slide 15.
- Such adjusting in height of the slide 15 can be done automatically and be controlled remotely.
- the setting means necessary for this can comprise a water level tube (not shown but conventional) which delivers a signal for operation of the spindle motor 17.
- the slide 15 of the polder weir 1 may be designed to be adjustable in height over a distance of approximately 2 m.
- an underground technical space may be provided for arranging appendages, such as a generator to be driven by the paddle wheel 3 and/or operating and monitoring means of the polder weir.
- the drive by the paddle wheel 3 of the generator (not shown, but conventional) may be implemented as a right- angle transmission or a toothed-belt drive, conventional in themselves.
- Measures for protecting the water population may have been provided by having a fish-friendly water guide put together with a fish- friendly paddle shape.
- a grid may be placed on the upstream side (not visible in the Figures, but conventional).
- FIG. 3 An alternative embodiment of the invention is shown in Figures 3 through 5.
- This concerns a river hydroelectric plant 101 preferably placed off the fairway along the bank of a river.
- this river hydroelectric plant 101 is anchored to a river groyne 150 in a manner so as to be movable up and down.
- This anchoring is implemented as a swiveling frame 102, which is hinged both to the groyne 150 and to an inner float 104 of the river hydroelectric plant 101.
- a paddle wheel 103 is set up rotatably for rotation around a horizontal shaft, which is bearing-mounted between the inner float 104 and an outer float 106.
- the inner and outer floats 104, 106 then serve also as channeling means for channeling a water stream under the horizontal shaft and within the range of the paddle wheel 103.
- a generator (not shown, but conventional) driven by the paddle wheel 103 may be accommodated in one of the inner or outer floats 104, 106. Also, there may be a generator for generating electric energy in each float.
- the outer float 106 is guided in its vertical movement relative to the river groyne 150 along a pole 108 anchored in the river bed, to which a beacon 110 for navigation is mounted.
- ballast tanks 112, 114 in the floats 104, 106 are implemented as ballast tanks 112, 114 in the floats 104, 106, as shown in Figure 5.
- a pump 116 is then in fluid communication with the ballast tanks 112, 114 by means of connecting conduits 118, 120 and with the surface water by means of an access conduit 122.
- the automatic setting of a position taken up by the waterwheel or paddle wheel 103 relative to the water surface 152 of the water stream can then be achieved by automatic control of the pump 116.
- the float 104, 106 as shown in Figure 5 has an open top, but is preferably closed, as can be seen in Figures 3 and 4.
- the channeling means may further also comprise a water guiding plate 109, as can be seen in Figure 4.
- This water guiding plate 109 may further, together with paddles of the paddle wheel 103, be made of fish- friendly design again.
- a trash or dirt guide 124 is arranged upstream, but in the case of river stretches subject to ebb and flow also downstream, of the paddle wheel 103.
- Such dirt guide can also serve to connect the inner and the outer floats 104, 106 with each other.
- a protective hood 126 which may be made of transparent material.
- grid floors 128 which extend in a horizontal plane above the floats 104, 106. These grid floors 128 also may be used to connect the inner and outer floats 104, 106 with each other.
- the paddle wheel of Figures 6 through 8, designated with reference numeral 301, is suitable for application both as the paddle wheel 3 in the implementation variant according to Figures 1 and 2 and as the paddle wheel 103 in the implementation variant according to Figures 3 through 5.
- the paddle wheel 301 has a core drum 303 which is rotatable around its own centerline, which coincides with a horizontally extending rotary shaft 305.
- a plurality of movable paddles 307 are arranged around the outer circumferential surface of the core drum 303. These paddles 307 are movably mounted between end flanges 309, which bound the core drum 303 at each axial end.
- each paddle 307 is mounted between the two end flanges 309 with a pivot 311. By means of the pivot 311, each paddle 307 can rotate between an active, substantially radial position, as shown for the left-hand half in Figures 6 and 7, and a passive, substantially tangential position, as shown in the right-hand half of Figures 6 and 7.
- Each paddle 307 further has a convexly shaped outer side 307A and a concavely shaped inner side 307B.
- a respective paddle 307 receives water from the water level 313 in the concavely shaped inner side 307B.
- the paddle wheel 301 is set into rotation in the direction of arrow 315.
- water is transported from the water level 313 to the lower-lying water level 317.
- the pivots 311 extend parallel to the centerline of the core drum 303 and hence are also parallel to the central horizontal shaft 305.
- the active position of each of the paddles 307 is defined in that the convexly shaped outer side 307A butts against a projecting stop 319, only one of which is visible in Figure 6.
- Figures 7 and 8 show these stops 319 more clearly.
- the paddle wheel 301 can also function as an overshot waterwheel. Also, when only the water level 317 is at hand, the paddle wheel 301 can also be driven in the same direction if the water level 317 is subject to a flow from left to right in Figure 6. In that case, an application variant such as that according to Figures 3 through 5 is involved.

- the I/O extension is configured to operate a switch 425, allowing a current source 427 to be connected, or not, with the supply 405 of the PLC unit 403.
- a monitoring module 429 which at low battery voltage can also switch off the communication module 417 by operation of a switch 431.
- the circuit in the monitoring module 429 switches on the communication module 417, and indirectly the PLC unit 403, every six hours so that a measurement can be done and the measuring data can be transmitted to a server via antenna 433.
- the monitoring module 429 measures the upstream water level via a sensor input 435. Should this water level within the period of six hours rise quickly (settable limit), the communication module 417 and the PLC unit 403 are switched on
- a signal connection 437 is connected from a charging current controller and limit switches to an input of the digital input module 411.
- a signal connection 439 is present for forwarding parameters such as: water levels, paddle wheel position, generator voltage, battery voltage, water flow rate, energy requirement, paddle wheel speed and camera registration.
