Definitions
- the invention relates to a shaft system for generating an artificial water wave according to the preamble of claim 1.
- the shaft systems described here are not only suitable for mobile, but especially for stationary use with increased reliability requirements.
- wave surfing develops a strong attraction for many water and recreational athletes.
- the surfer uses the formation of waves in a liquid, which is typically water.
- the wave must therefore be suitable to carry the surfer on a surfboard. It is therefore a standing wave.
- the surfer can ensure his stay on the wave or the wave crest.
- the surfer is typically dependent on suitable conditions prevailing in natural moving waters, such as rivers or the open sea, which allow the formation of waves. These waves can then be used for surfing. Depending on the boundary conditions, these are either standing waves, such as in rivers or canals with barrages, or even running waves, such as in the open sea.
- An artificial wave system is described in EP 2 180 927 A2 with a wave basin and a main basin.
- the water used as liquid is pumped by means of several pumps from a main pool in a wave pool in which a wave is excited by a guide element. From the wave pool, the water then flows back into the main pool.
- the required pumps are located directly in the water of the main basin in order to ensure the high throughputs.
- a disadvantage of the known wave systems that the water is circulated more or less continuously in wave operation of the plant of the wave pool due to the large flow rates.
- the wave plant In the wave plant but is in different areas and basins, especially in the wave pool and / or in the main pool, but also in the conveyor line and / or in the lines, larger and smaller amounts of stagnant water.
- the required drinking water quality in stationary operation can not be achieved.
- a risk to the surfer and other persons should be prevented or at least reduced by a lack of water quality.
- a shaft system for generating an artificial wave with the features of claim 1 solves this problem.
- Such a wave device is provided for generating an artificial water wave for surfing.
- At least one wave basin which can be flowed through by a liquid, in particular water, from an inlet to a drain.
- a liquid in particular water
- the wave pool is preferably a particular adjustable guide device for exciting arranged for a while in the flowing liquid.
- a guiding element for example, serve a plate or a flow wedge.
- At least one feed pump is provided for conveying liquid emerging from the outlet of the wave pool via one or at least one conveying line to the inlet for flowing through the wave tank.
- At least one electrical component preferably at least one electrical device or at least one electrical component of the at least one feed pump, in the region of the conveying path between the outlet and inlet of the wave pool.
- the shaft system is characterized in that an at least substantially continuous flow through the wave pool is provided even without shaft operation. This ensures that stagnant water is prevented and thus the water quality increases.
- the flow serves the regular or continuous exchange of water, in particular as circulation or as circulation. Since such a system is usually classified as a swimming pool system, at least during stationary operation, correspondingly high demands are placed on the water quality. Above all, the so-called swimming pool standard must be adhered to in this case.
- At least substantially a continuous flow takes place in comparison to the wave operation low throughput of water. This means that much less water per unit of time is expended for the flow than for the wave operation.
- wave operation typically several thousand liters of water are pumped per minute. Meanwhile, to maintain flow only throughputs of typically a few liters per minute up to several hundred liters per minute are required. This can also be a throughput split over several nozzles.
- a regular exchange of water in the system preferably the entire water in the system. This is preferably true for virtually all areas of the plant.
- the at least one pump ensures the substantially continuous flow.
- one or more of the pumps is preferably operable individually. These are preferably the pumps for operating the wave generation.
- the existing pumps are also used to provide the flow. Additional pumps are then preferably not required.
- diversions and / or branches for parts of the existing water flow can be provided. Thus, a targeted flow of water through the pool can be made to flow, which can differ from that in wave operation.
- At least one additional flow-through pump is provided for ensuring the substantially continuous flow, preferably of the at least one basin, in particular wave pool.
- a flow pump may be adapted to the specific requirements of the flow, for example with regard to throughput and adjustability. It can also be provided for this purpose corresponding water pipes, optionally as additional lines, and / or nozzles. Thus, a targeted flow can be achieved.
- the at least one pump and / or the at least one flow-through pump are / can be regulated and / or switched in their performance.
- the at least one pump for wave generation as well as the at least one flow pump can optionally be operated individually and / or with lower power.
- the required throughput can be adapted to the requirements of the flow. This is particularly necessary in the case of the at least one pump for generating waves, since these are typically provided for large throughputs of water.
- the continuous flow in the main flow direction of the wave operation is provided. This means that the water flows through it virtually the same way as in wave operation. Thus, additional installations and precautions can be avoided.
- the pumps and lines of wave operation are used. If necessary, even additional pumps and / or lines and / or nozzles can be dispensed with. At least, however, this particular but their number and throughput compared to the usual required level can be reduced.
- the substantially continuous flow is provided in a preferred embodiment of the invention at an angle to the main flow direction of the Welien horrs, preferably at least substantially perpendicular thereto. This allows a particularly targeted flow. This ensures optimal flow.
- the substantially continuous flow through is provided in all basins or nearly all basins, in particular at least wave basins and / or main basins, and / or conveying sections and / or lines.

- a plurality of water nozzles are arranged to flow through.
- Such nozzles are used specifically for the purpose of flow. Their design and / or arrangement can be optimally adapted to the purposes of the flow. Thus, a special flow can also be achieved depending on the position of the respective nozzle.
- At least one water treatment plant is provided to ensure the water quality.
- the water treatment plant is preferably at least partially integrated into the water cycle for continuous flow and / or the water cycle of the Weilen worriess.
- the water treatment plant can work in the usual way by means of filters and / or chemical and / or biological water treatment. It can also be provided several water treatment plants, possibly also different. This ensures that the water quality can be maintained at a high level, preferably on drinking water quality.
- At least one additional basin is provided for the provision and / or temporary storage of water in different operating states of the wave installation.
- the at least the additional basin may preferably be used as a water reservoir for use as extinguishing water and / or Sprinklerwasser be provided.
- the additional basin can be used to flexibly adapt the water level or the water levels in the basins and / or conveyor lines and / or lines of the wave system to the particular desired application.
- the water in the additive tank but possibly also the water in the rest of the wave system, used as fire extinguishing water and / or sprinkler water in a fire or similar situations.
- the wave plant preferably at least the wave basin and / or the main basin, is flooded or flooded so that the Welienstrom, preferably at least the wave pool and / or the main pool, is usable as a swimming pool.
- a further use of the wave system can be achieved as a swimming pool.
- a continuous water surface is provided. This is achieved in particular by covering the entire water-bearing areas of the plant with water, so practically a complete flooding of the plant.
- a water level can be provided up to the top of a wall or wall, especially in the manner of a basin without clearly visible edge, such as a so-called "infinity pool".
- transparent components in particular made of glass or plastic, for walls and other elements of the wave plant and / or their sub-areas can be used, so that a clear view into the pool or out of the pool is possible.
- at least some elements in the pool, such as parts of the wave pool itself, can be virtually invisible when the wave plant flooded.
- a cover for at least part or all of the water surface preferably at least at least one of the basins, the main basin and / or the wave pool is provided.
- the cover is particularly designed such that use of the covered area can be done for other purposes. For example, a use as event space, sales area, catering area or the like can serve.
- the cover serves in particular as the bottom of the corresponding surface. In this case, the continuous flow is of particular interest, because the Welienstrom is under the cover and so automatically maintain the water quality.
- the cover or the area created by it is therefore particularly accessible.
- it is loadable with the usual ceiling loads, for example, up to 250 kilograms per square meter or even up to 500 kilograms per square meter or more, possibly even only reduced by up to 125 kilograms per square meter or less.
- the cover is composed of a plurality of elements, wherein preferably the elements are interchangeable, optionally at least partially against each other.

- FIG. 1 is a side sectional view of a shaft system according to the invention at rest
- Fig. 2 is a side sectional view of the shaft system of FIG. 1 in operation
- FIGS. 1 and 2 a shaft system 10 according to the invention is shown in a lateral, partial sectional view at rest or in operation.
- the shaft system 10 has a wave basin 11 with a guide device 12.
- the guide device 12 serves to excite a wave 14 in a flowing liquid, such as the water 13 shown here, as shown in FIG. 2.
- a guide 12 here a quarter-circle-shaped element is used, which is pivotable about a horizontal axis of rotation up and down.
- the guide device 12 is completely retractable in a recess or depression at the bottom of the wave tank 11 in order to achieve a smooth bottom. In operation, the guide device 12 is pivotable out of this recess in order to be able to excite a shaft 14.
- a simple baffle can be used as a guide 12.
- the water 13 is in the illustrated embodiment by means of a pump 15 or feed pump from a main basin 16 via a Conveyor line 17 promoted in the wave pool 1 1.
- a pump 15 or feed pump from a main basin 16 via a Conveyor line 17 promoted in the wave pool 1 1.
- a tubular pump chamber 18 is provided. This is shown here as a U-shaped pump chamber 18. But it can also take other suitable forms, such as L-shaped or as a simple vertical tube. Also conical tube profiles are conceivable.
- the pump chamber 18 may have a round, oval, rectangular or polygonal design, possibly also partially different.
- the electric drive 19 is namely outsourced entirely from the area of the liquid 13.
- the drive 19 and also other components such as the power supply, the drive 19 and so on are arranged here in a separate space 27.
- This is not shown here in detail implementation through the walls of the pump housing 17 as well as the room 27 required together with a corresponding storage and sealing.
- These mechanical seals which are not shown here in detail, can be used without endangering the surfer. For example, glands or the like can be used for this purpose.
- the pump 15 shown here as an impeller is arranged, which has a motor drive 19.
- the motor drive 19 is an electric motor.
- the pump chamber 18 in this case has a Einiass 20 for sucking water 13 and an outlet 21 for discharging the sucked water 13.
- the Einiass 20 is arranged for this purpose in the main basin 16, in particular below the water level.
- a ramp 22 is shown, via which the water 13 is conducted into the actual wave basin 11. Because of the sloping at a shallow angle down ramp 22 develops here typically an accelerated, but rather substantially laminar flow of the liquid 13,
- a drain 23 for the water 13 is present. Through this drain 23 through the water 13 can flow back into the main basin 16.
- the drain 23 may be formed, for example, as a perforated plate or grate to let pass the large amounts of water can occur.
- only a single pump 15 is shown in the sectional view. In practice, however, a plurality of pumps 15 are typically arranged next to one another, ie actually one behind the other, perpendicular to the plane of the drawing, thus concealed in this representation and therefore not visible. This is necessary in order to be able to provide the required throughput of water 13 on the widest possible surface of the wave pool 11.
- the at least one pump 15 ensures that the water 13 is conveyed out of the main basin 16 into the wave basin 11.
- the main basin 16 thus serves as a reservoir for the water 13.
- the conveyed into the wave pool 1 1 13 flows through this water in the direction of the drain 23. There it flows down into the main basin 16.
- the flow direction of the water 13 is indicated by arrows
- the shaft system 10 is in the present embodiment, the water level below the lower edge of the wave tank 11. Accordingly, the water 13 flows almost completely out of the wave pool 1 1 after switching off the pump 15. After this short drainage phase, the water level in the wave basin 11 in the idle state of the pumps, the water 13 is virtually zero.
- the wave pool 11 fills immediately back up to a certain minimum level, So in the operating state, a certain amount of water 13 in the wave tank 11 is always present. Conversely, however, it is also avoided at the same time that a significant amount of water 13 is still present in the wave tank 1 1 in the resting state, which may need to be monitored and possibly cleaned. Since the amount of water delivered by the pumps 15 is relatively large in comparison to the outlet 23 , In the operating state, a certain amount of water 13 will be permanently present in the wave pool 11. Thus, this water 13 in the wave pool 11 can ensure that a shaft 14 can be excited by means of the guide device 12.
- the drain 23 may for this purpose also have a water level-dependent or height-dependent permeability.
- different free cross sections of the drain 23 may be provided, so that depending on the water level different throughputs of water 13 are possible. This means that a lower throughput of water 13 per unit of time is possible in the lower region of the outlet 23 than in its upper region. This can be ensured, for example, by differently formed openings in the outlet 23, that is to say in concrete terms, for example, different number of holes, hole size and / or hole spacing.
- a height-dependent variation of the free cross-section may provide for a lower throughput at the bottom and higher throughput at the top.
- the wave pool 1 1 but also include a lot of water. This is achieved by the tank 1 1 is not completely empty due to the sequence design.
- the drain 23 may, for example, have a water-impermeable bottom-side section, so that a remainder Water in the pool 11 stops. This water should then be circulated regularly to avoid contamination and stagnant water.
- the already mentioned at least one drive motor 19 is provided.
- a separate drive 19 is typically provided.
- a plurality of pumps 15 may have a common drive 19.
- the drive 19 is arranged in the present case within the pump chamber 18 and thus in the water 13.
- a cable 24 serves to supply the drive 19 with electrical energy. Accordingly, both the drive motor 19 and the cable 24 is consuming to isolate electrically. This applies to each drive 19 together with cable 24 individually or together for several pumps 15th
- the cable 24 connects the drive 19 with a power supply 26 for the pump 15.
- the power supply 26 is disposed outside the water 13, here in a separate housing or space 27.
- the drive 19 and the actual pump 15 are in the usual way connected by a short drive shaft 28.
- a plurality of nozzles 25 are shown in each case. These nozzles 25 serve to provide a flow through the water-bearing areas of the shaft system 10.
- 17 nozzles 25 arranged in the basin 11 and 16 as well as conveyor line.
- By means of these nozzles 25 shown here water is introduced laterally into the respective water-bearing areas. The direction of introduction thus runs essentially perpendicular to the main flow direction, which is marked here with arrows.
- an additional, not shown here flow pump is provided for the promotion or circulation of the water by means of the nozzles 25.
- This flow pump conveys the water through the nozzles 25 into the respective areas.
- a water treatment plant not shown here, may be provided, for example with filters and / or chemical and / or biological purification.
- the pumps 15 can be used for the shaft operation for the flow. These are then to operate with low power or only individually.
- the shaft assembly 10 is shown with a cover 29 also in a side, partial sectional view.
- the cover 29 is placed here on a peripheral edge 30 of the shaft system 10. As shown here, the cover 29 may be laid up. It may also be provided guide rails or the like. The cover 29 forms a substantially flat surface. This area is particularly suitable as an event space, sales area or the like. It is therefore particularly walkable and resilient.
- the cover 29 is formed here of individual elements 31. These elements 31 are assembled to the cover 29. The elements 31 are made to fit each other, for example, according to a tongue and groove principle.
- at least one seal may be provided, in particular for the abutting areas of the elements 31 to each other.
- Also for the edge region of the cover 29 may be provided a seal.
- the elements 31 can be removed from the pelvic area and then stored at a suitable location, for example in a specially provided frame or room.
- a high water level 32 is additionally shown in FIG. This is to show the case of the use of the wave system 10 and the wave pool 11 as a swimming pool. It can be seen here that virtually all internals in the shaft system 10 are below the water level of the high water level 32. This allows a smooth water surface in swimming pool operation can be achieved. LIST OF REFERENCE NUMBERS
