Definitions

  • the invention relates to a wave system for generating an artificial water wave according to the preamble of claim 1.
  • the wave systems described here are not only suitable for mobile, but above all for stationary use with increased demands on operational safety.
  • wave surfing develops a strong attraction for many water and recreational athletes.
  • the surfer takes advantage of 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 that he remains on the wave or the crest of the wave.
  • the surfer is typically dependent on suitable conditions in natural moving waters, such as rivers or the open sea, that enable waves to develop. 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 moving waves, such as in the open sea.
  • An artificial wave system describes the EP 2 180 927 A2 with a wave pool and a main pool.
  • the water used as a liquid is pumped from a main pool into a wave pool by means of several pumps, in which a wave is excited by a guide element.
  • the water then flows from the wave pool back into the main pool.
  • the pumps required for this are located directly in the water of the main basin in order to be able to ensure the high throughputs.
  • the disadvantage of the known wave systems is that the water is circulated more or less continuously during wave operation of the system of the wave pool due to the large flow rates.
  • the wave system there are larger and smaller amounts of standing water in various areas and pools, such as in particular in the wave pool and / or in the main pool, but also in the conveyor line and / or in the lines.
  • the required drinking water quality in particular cannot be achieved in stationary operation.
  • a wave system for generating an artificial wave with the features of claim 1 solves this problem.
  • Such a wave system is provided for generating an artificial water wave for surfing.
  • it has at least one wave pool through which a liquid, in particular water, can flow from an inlet to an outlet.
  • a liquid in particular water
  • a plate or a flow wedge, for example, can serve as the guide element.
  • At least one feed pump is provided for conveying liquid emerging from the drain of the wave pool via one or at least one conveying path to the inlet for flowing through the wave pool.
  • At least one electrical component preferably at least one electrical device or at least one electrical component of the at least one delivery pump, in the area of the delivery path between the outlet and inlet of the wave basin.
  • the wave system is characterized in that an at least substantially continuous flow through the wave basin is provided even without wave operation. This ensures that standing water is prevented and thus the water quality increases.
  • the flow serves the regular or continuous exchange of the water, in particular as circulation or recirculation. Since such a system is usually classified as a swimming pool system, at least in stationary operation, there are correspondingly high demands on the water quality. Above all, the so-called swimming pool standard must be observed in this case.
  • a low throughput of water compared to wave operation.
  • wave operation several thousand liters of water are typically pumped per minute. Meanwhile, only throughputs of typically a few liters per minute up to a few hundred liters per minute are required to maintain the flow.
  • This can also be a throughput divided between several nozzles. In this way, the water in the system can be regularly exchanged with a low throughput, preferably all of the water in the system. This preferably applies to practically all areas of the system.
  • the at least one pump ensures the essentially continuous flow.
  • one or more of the pumps can preferably be operated individually. These are preferably the pumps for operating the wave generation. This is how they are Existing pumps are also used to provide the flow. Additional pumps are then preferably not required. If necessary, diversions and / or branches can also be provided for parts of the existing water flow. This allows a targeted flow of water through the basin to flow through, which can deviate from that in wave operation.
  • At least one additional flow pump is provided to ensure the essentially continuous flow, preferably the at least one basin, in particular the wave basin.
  • a flow pump can be adapted to the special requirements of the flow, for example with regard to throughput and adjustability.
  • Corresponding water lines, if necessary as additional lines, and / or nozzles can also be provided for this purpose. In this way, a targeted flow can be achieved.
  • the output of the at least one pump and / or the at least one flow pump can be regulated and / or switched.
  • the at least one pump for generating waves and the at least one through-flow pump can each be operated individually and / or with a lower power, if necessary.
  • the required throughput can thus be adapted to the requirements of the flow. This is necessary in particular 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 is provided in the main flow direction of the wave operation. This means that the water flows along practically the same path to flow through as it does when operating waves. This means that additional installations and precautions can be avoided.
  • the pumps and lines for shaft operation are used here. If necessary, additional pumps and / or lines and / or nozzles can then even be dispensed with. At the very least, their number and throughput can thereby be reduced compared to the amount usually required.
  • An additional, essentially continuous flow is provided in a preferred embodiment of the invention at an angle to the main flow direction of the wave operation, preferably at least essentially perpendicular thereto. This enables a particularly targeted flow. In this way, an optimal flow can be ensured.
  • the essentially continuous flow is provided in all basins or almost all basins, in particular at least wave basins and / or main basins, and / or conveyor lines and / or lines. This ensures that all water-bearing areas of the wave layer are traversed. In this way, standing water with the risk of contamination can be optimally avoided.
  • a plurality of water nozzles are arranged for flow through.
  • Such nozzles are used specifically for the purpose of flow. Their design and / or their arrangement can be optimally adapted to the purposes of the flow. A special flow can thus also be achieved depending on the position of the respective nozzle.
  • At least one water treatment system is particularly preferably provided to ensure the water quality.
  • the water treatment system is preferably at least partially integrated into the water circuit for continuous flow and / or the water circuit of the shaft operation.
  • the water treatment system can work in the usual way by means of filters and / or chemical and / or biological water treatment. Several water treatment systems can also be provided, possibly also different ones. This ensures that the water quality can be kept at a high level, preferably drinking water quality.
  • At least one additional basin is provided for the provision and / or intermediate storage of water in different operating states of the wave system.
  • the at least one additional basin can preferably be used as a water reservoir for use as extinguishing water and / or Sprinkler water may be provided. This may result in double use.
  • 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 intended use.
  • the water in the additional basin in particular, but possibly also the water in the rest of the wave system, can be used as extinguishing water and / or sprinkler water in the event of a fire or similar situations.
  • the wave system preferably at least the wave pool and / or the main pool, is floodable or floodable in such a way that the wave system, preferably at least the wave pool and / or the main pool, can be used as a swimming pool.
  • a continuous water surface is preferably provided. This is achieved in particular by covering the entire water-bearing areas of the system with water, that is to say practically complete flooding of the system.
  • a water level up to the upper edge of a wall or wall can also be provided, in particular in the manner of a basin without a clearly visible edge, such as a so-called "infinity pool".
  • transparent components in particular made of glass or plastic, can be used for walls and other elements of the wave system and / or their sub-areas, so that a clear view into the water basin or out of the basin is possible. In this way, at least some elements in the pool, such as parts of the wave pool itself, can be practically invisible when the wave system is flooded.
  • a cover is preferably provided for at least part or the entire water surface, preferably at least one of the pools, the main pool and / or the wave pool.
  • the cover is designed in particular in such a way that the covered area can be used for other purposes. For example, it can be used as an event area, sales area, restaurant area or the like.
  • the cover serves in particular as the bottom of the corresponding surface. In this case the continuous flow is of particular interest, because the wave system is located under the cover and must therefore automatically maintain the water quality.
  • the cover or the area created by it is therefore particularly accessible. It can preferably be loaded 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 only reduced to up to 125 kilograms per square meter or less.
  • the cover can preferably be composed of a plurality of elements, the elements preferably being interchangeable, optionally at least partially with one another.
  • the cover can thus be assembled from several components in a simple manner. If necessary, individual elements of the cover can be replaced in the event of defects, for example. If necessary, for the sake of simplicity, at least individual elements can also be exchanged for one another, at least if they have the same dimensions.
  • the elements are preferably manufactured to fit one another with an exact fit, for example according to a tongue and groove principle. If necessary, at least one seal can also be provided for joint areas and / or edge areas of the cover and / or the elements. In particular, the elements can be removed from the pelvic area. They can be stored in a suitable place, for example in a frame and / or room provided for this purpose.
  • the cover or its parts or elements can be moved by a motor, preferably moved, but optionally also manually.
  • the parts or elements can preferably be locked, in particular with one another.
  • the locking can be done by a motor, in particular electrically, but also manually if necessary.
  • a partially automatic or even fully automatic opening and / or closing of the cover can thus be made possible.
  • Guide rails or other guide means can also be provided for the elements of the cover. In particular in the case of guide rails that run essentially horizontally, guidance by means of sliding or rolling elements can be provided, preferably in or on the guide rail. Also can get funding and / or tension elements such as belts, toothed belts, motorized drives or the like can be provided.
  • a shaft system 10 according to the invention is shown in a lateral, partial sectional view at rest or in operation.
  • the wave system 10 has a wave pool 11 with a guide device 12.
  • the guide device 12 serves to excite a wave 14 in a liquid flowing past, such as the water 13 shown here, as in FIG Fig. 2 is sketched.
  • a quarter-circle-shaped element is used here as the guide device 12, which element can be pivoted upwards and downwards about a horizontal axis of rotation.
  • the guide device 12 can be completely lowered into a recess or depression on the bottom of the wave basin 11 in order to achieve a smooth bottom. During operation, the guide device 12 can be pivoted out of this recess in order to be able to excite a shaft 14.
  • a simple guide plate can also be used as guide device 12.
  • the water 13 is in the embodiment shown by means of a pump 15 or feed pump from a main basin 16 via a Conveyor line 17 promoted into the wave pool 11.
  • a pump 15 or feed pump from a main basin 16 via a Conveyor line 17 promoted into the wave pool 11.
  • only one pump 15 will be used as an example, although several pumps 15 are always conceivable or, conversely, only one pump 15 instead of several.
  • a tubular pump chamber 18 is initially provided here. This is shown here as a U-shaped pump chamber 18. However, it can also take on other suitable shapes, for example L-shaped or as a simple vertical tube. Conical tube profiles are also conceivable. In cross section, the pump chamber 18 can have a round, oval, rectangular or also polygonal design, possibly also different in sections.
  • the electric drive 19 is completely removed 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 in a separate room 27 here.
  • the drive shaft 28 is used here to connect the actual pump 15 to the separate drive 19 in the separate space 27.
  • a passage through the walls of the pump housing 17 and space 27, not shown in detail, is required along with a corresponding bearing and sealing.
  • the pump 15, shown here as an impeller and having a motor drive 19, is arranged in this pump chamber 18.
  • the motor drive 19 is an electric motor.
  • the pump chamber 18 has an inlet 20 for sucking in water 13 and an outlet 21 for ejecting the sucked water 13.
  • the inlet 20 is arranged in the main basin 16, in particular below the water level.
  • a ramp 22 is shown here, via which the water 13 is directed into the actual wave pool 11. Because of the ramp 22 running obliquely downwards at a shallow angle, it develops here typically an accelerated but rather essentially laminar flow of the liquid 13.
  • the drain 23 can for example be designed as a perforated plate or grate in order to allow the large amounts of water to pass through.
  • the at least one pump 15 ensures that the water 13 is conveyed from the main pool 16 into the wave pool 11.
  • the main basin 16 thus serves as a reservoir for the water 13.
  • the water 13 conveyed into the wave basin 11 flows through it in the direction of the drain 23. There it flows down into the main basin 16.
  • the direction of flow of the water 13 is indicated by arrows.
  • the water level in the wave pool 11 is practically zero when the pumps are at rest.
  • the wave pool 11 immediately fills up again to a certain minimum height. In this way, a certain amount of water 13 is always present in the wave pool 11 in the operating state. Conversely, this avoids, however, at the same time that a significant amount of water 13 is still present in the wave pool 11 even in the resting state, which water may have to be monitored and possibly cleaned.
  • the drain 23 can also have a water level-dependent or height-dependent permeability. Different free cross-sections of the drain 23 can therefore be provided, so that different throughputs of water 13 are possible depending on the water level. This means that a lower throughput of water 13 per unit of time is possible in the lower region of the drain 23 than in its upper region. This can be ensured, for example, by differently designed openings in the outlet 23, that is to say specifically, for example, different numbers of holes, hole sizes and / or hole spacings.
  • a height-dependent variation of the free cross section can, for example, ensure a lower throughput at the bottom and a higher throughput at the top.
  • the wave pool 11 can also contain a lot of water. This is achieved in that the basin 11 does not run completely empty due to the design of the drain.
  • the drain 23 can, for example, have a water-impermeable bottom section, so that a remainder Water in the basin 11 remains. This water must then be circulated regularly to avoid contamination and stagnant water.
  • the at least one drive motor 19 To drive the at least one pump 15, the at least one drive motor 19 already mentioned is provided. A separate drive 19 is typically provided for each pump 15. If necessary, several pumps 15 could also have a common drive 19. In the present case, the drive 19 is arranged within the pump chamber 18 and thus in the water 13. A cable 24 is used here to supply the drive 19 with electrical energy. Accordingly, both the drive motor 19 and the cable 24 have to be electrically insulated in a complex manner. This applies to each drive 19 together with the cable 24 individually or also jointly for a plurality of pumps 15.
  • the cable 24 connects the drive 19 to a power supply 26 for the pump 15.
  • the power supply 26 is arranged 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 to one another by a short drive shaft 28.
  • nozzles 25 are shown in each case. These nozzles 25 are used to ensure a flow through the water-carrying areas of the wave system 10. For this purpose, nozzles 25 are arranged in the area of the basins 11 and 16 as well as the conveyor line 17.
  • An additional flow pump is provided for conveying or circulating 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 system (not shown here) can be provided, for example with filters and / or chemical and / or biological cleaning.
  • the pumps 15 for shaft operation can also be used for the flow. These are then to be operated with low power or only individually.
  • the cover 29 is placed here on a circumferential edge 30 of the shaft system 10. As shown here, the cover 29 can be placed on top. Guide rails or the like can also be provided. The cover 29 forms an essentially flat surface. This area is particularly suitable as an event area, sales area or the like. It is therefore particularly accessible and resilient.
  • the cover 29 is formed here from individual elements 31. These elements 31 are assembled to form a cover 29.
  • the elements 31 are manufactured to fit one another precisely, for example according to a tongue and groove principle.
  • at least one seal can also be provided, in particular for the abutment areas of the elements 31 against one another.
  • a seal can also be provided for the edge region of the cover 29.
  • the elements 31 can be removed from the pelvic area and then stored in a suitable location, for example in a specially provided frame or room.
  • a high water level 32 is also shown. This should show the case of the use of the wave system 10 or the wave pool 11 as a swimming pool. It can be seen here that practically all of the built-in components in the wave system 10 are below the water level of the high water level 32. This enables a smooth water surface to be achieved in swimming pools.
