Description
Marina system with a hydroelectric power plant, and a pump module The invention relates to a marina system with a hydroelectric power plant. The inven-tion also relates to a corresponding pump module.
A marina, also called a marina, is a port with moorings, berths and facilities for sailing and motor yachts. The marina provides shelter for the vessels inside and has sluices between a main basin and the open sea.
During each sluice operation, water losses from the main basin into the sea can oc-cur, which must be compensated for again in order to maintain as continuous a water level as possible in the main basin and thus in the berths. For this purpose, corre-sponding pumps with the associated energy input are required.
The document WO 2013/006136 Al describes several fluid pumping devices and their applications for power generation from waves or currents. The pumping devices are driven by a float, an oscillating pontoon and an oscillating paddle, an impeller, a vertical rotating wheel or a pendulum element. The pumped fluid (water and/or air) is fed to drive a fluid motor M or a turbine T, which in turn drives a generator G to pro-duce electrical energy.
In the context of ever-increasing demands for environmental sustainability and simul-taneous cost containment, there is a need for improved and energy-saving equip-ment.
Therefore, the object of the present invention is to provide an improved marina sys-tem with hydroelectric power plant.
The task is solved by a marina system with the features of claim 1.
A marina system according to the invention comprises at least one berth for boats, at least one sluice chamber with two sluice gates each, and a hydroelectric power plant for supplying the marina system with water. The hydroelectric power system com-prises at least one pump module driven by wave motions of a sea section.
With this pump module, which is driven by wave movements, it is possible to continu-ously feed a water balance of the marina system in an advantageous energy-saving manner.

2 A pump module according to the invention for a marina system described above is created.
This pump module can also be used in other scenarios, e.g. pumping and conveying water, generating compressed air for example on oil rigs, etc.
Advantageous further embodiments of the invention are indicated by the objects of the subclaims.
In one embodiment, the at least one pump module of the hydroelectric power plant is connected to a storage device via a flow-through unit, wherein the flow-through unit comprises a turbine with a power generator. An advantage here is that not only a storage device can be used as a buffer storage, but that the flow energy of the water can be utilized at the same time.
This is even more advantageous if the accumulator is equipped with at least one fur-ther flow unit as an outlet with a turbine with power generator.
In one embodiment, an outlet of the reservoir opens into a manifold unit that branches the outlet into a basin feed line for a main basin of the marina and a sluice feed line with a sluice manifold, the main basin having at least one main outlet that has a flow unit with power generator and control valve, the sluice manifold having an overflow with a flow unit with power generator. In this way, the energy of many water flows can be advantageously utilized.
It is also of great advantage if an intermediate storage device is associated with the marina, fed by a float chamber via at least one inlet turbine with a directional valve, the float chamber being filled by the tidal range of a sea section and supplying the water thus stored to the intermediate storage device, since in this way it can be used even in the event of level changes of long duration, such as during tidal surges.
In a further embodiment, additional storage devices for water, electricity storage and/or compressed air storage are associated with the marina, which are filled di-rectly or indirectly by at least one pump module. The advantage here is that such a pump module can not only pump water, but is also capable of compressing air and thus generating compressed air. Furthermore, the water pumping can also drive power generators with corresponding turbines and thus provide electrical energy, which can then be used to supply or provide emergency power to the marina's facili-ties.

In order to exploit wave movements in different directions, the hydroelectric power plant can have at least one pump module around which several drive devices are ar-ranged in a circle. Naturally, other geometric shapes, such as oval, polygon, etc., can be used instead of a circle.

correspond-ing control system is provided for this purpose so that water loss during sluicing oper-ations can be reduced.
The inner sluice gates 15, 15a open only when the respective level of a sluice cham-ber 14, 14a corresponds to the level of the main basin. The outer sluice gates 16, 16a open only when the chamber water level corresponds to the outer water level.

6 .. pump stator 21 is connected to the stationary pump frame 20 and has the outlet line 3 in its upper region.
The float unit 24 is moved by water movements of the sea section M so that it trans-mits these movements to the drive frame 23 for actuating the pump module 2 to pump water.
The pump stator 21 and the pump actuator 22 are formed as tubes with a circular cross-section and are arranged coaxially with respect to each other and with respect to the vertical axis H. The pump stator 21 has an end region with an inlet 29 on its underside, which is surrounded by a circumferential wall 29a with inlet openings 29b.
The underside may also be additionally provided with a filter material. Above this, a first valve unit 27 is mounted in the pump stator 21. A first pump chamber 21a is ar-ranged above the first valve unit 27, in which the pump actuator 22 is displaceably guided. At least one circumferential seal 26 seals the first pump chamber 21a from the atmosphere communicating with the upper opening of the pump stator 21.
The pump actuator 22 is provided with a second valve unit 28 on its underside.
The space above is referred to as the second pump chamber 22a and is closed at the top. The outlet line 3 communicates with the second pump chamber 22a.
The first valve unit 27 and the second valve unit 28 are connected in series, whereby valve planes of the valve units 27, 28 move relative to each other during operation of the pump module 2. They may also have more than two valve flaps 31, 31a.
The hydroelectric power plant 1 is actuated by shaft movements via the drive frame 20. In the process, the pump actuator 22 is moved axially in the direction of the verti-cal axis H towards the underside with the first valve unit 27 of the pump stator 21, which is fixed in this case. Thereby, the first valve unit 27 closes and the water lo-cated in the section of the first pump chamber 21a flows through the opening second valve unit 24 into the second pump chamber 22a. When the pump actuator 22 moves upward, the second valve unit 24 closes and the water in the second pump chamber 22a is compressed and forced out through the outlet line 3. At the same time, the first valve unit 27 opens and water flows through it into the first pump chamber 21a, as-sisted by a negative pressure forming in the first pump chamber 21a triggered by the upwardly moving pump actuator 22.

7 The valve unit 27, 28 is designed here as a flap valve with two valve flaps 31, 31a, both of which can be pivoted about a common pivot axis 30a in a valve frame 30. In the open state, the valve flaps 31, 31a are open in the direction of flow (arrow) of the medium flowing through, in this case water. If the direction of flow of the medium changes, the valve flaps 31, 31a close again. The valve unit 27,28 is a directional valve.
Fig. 6 shows a schematic view of the pump module 2 according to Fig. 2-3 with an exemplary drive device 33.
In this example, the drive device 33 has lever arms 33a and 33b which are articu-lated to each other and to the float unit 24 by joints 33c, 33d. The lever arm 33a is ar-ticulated to an input of a gear unit 32 and coupled via the latter to the drive frame 23 and to the pump actuator 22, respectively. For example, the gear unit 32 may have a gear pinion in engagement with a gear rack, the gear pinion being connected to the lever arm 33a and the gear rack being attached to the pump actuator 22. Of course, other types of gearing are possible which convert the reciprocating motion of the float unit 24 into reciprocating axial motion of the pump actuator 22.
In order to convert wave movements from and in all possible directions into pumping movements, several drive devices 33 can be arranged, for example, in a circle.
This is shown in Fig. 7, which is a schematic top view of a variant of the marina system according to Fig. 1.
The float units 24 are coupled to the pump module 2 or multiple pump modules 2 via float arms 24a and float joints 24b. The float units 24 may also be float units 24' filla-ble with a medium. In addition, weights 36 may be provided as a balance on the drive devices 33. In the arrangement of pump modules 2 shown here, an empty chamber 37 and an interception chamber 38 are also arranged, which can have protective and filter functions.
As shown, the pump modules 2 can fill additional storage devices 6 with water.
In ad-dition, in an embodiment not shown but imaginable, they can generate electricity in conjunction with turbine generators, which can be stored in a current storage 35 and fed into an electricity grid in a suitable manner or consumed on site.
Between the sluice chambers 14, 14a, a float chamber SK with an intermediate stor-age ZS is also arranged here, which is shown in Fig. 8 in a schematic sectional view of the intermediate storage ZS of the marina system.

8 The intermediate storage ZS is connected via at least one inlet turbine 42 with a di-rectional valve (not shown) to an intermediate inlet ZL, which in turn is fed by the float chamber SK. The float chamber SK has a float 39 with a turbine chamber 40 mounted thereon with a turbine 41, both of which are movably arranged in the float chamber SK up and down in a float stroke SH.
The sea section M is located on one side of the float chamber SK. The sea section M
has a tidal range TH with high water HW and low water NW. In front of an inlet 40a formed in the side of the float chamber SK facing the sea section M, a ramp device 44 is provided which is connected to the float 39 and moves with it. The ramp device 44 serves to allow waves 45 to pass through the inlet 40a into the float chamber SK
and operate the turbine 41. In this way, the tidal range TH of the sea section M can also be exploited, filling the float chamber SK through it and supplying the water thus stored to the intermediate storage ZS via the intermediate inlet ZL. At the same time, the flow energy of the incoming (and also outgoing) water can be utilized.
Additionally, the ramp device 44 carries a protective screen and filter, not shown, which both prevents contaminants from flowing in and provides a barrier to marine life.
When the high water HW is reached, the water in the intermediate storage ZS
also has this level. The water stored in the intermediate storage ZS can now be used in turn by feeding it through a discharge turbine 43 with directional valve via a discharge line 43a to a pump module 2 which fills the sluice chamber 14, 14a via its outlet line 3. The water draining from turbine 41 (or float chamber SK) can also be fed via tur-bine line 41a to still another pump module 2, which also fills sluice chamber 14, 14a with its outlet line 3.
The two further pump modules 2 (or also several) can be driven, for example, by electric motors or compressed air motors by means of stored energy from the current storage 35 or/and compressed air storage 34. Drive devices 33 as described above are of course also conceivable.
The invention is not limited by the embodiments disclosed above, but may be modi-fied within the scope of the claims.
For example, it is conceivable that the pump stator 21 may also be driven.
