Description

Apparatus and method for generating a wave profile in water

The invention relates to an apparatus and a method for producing a wave profile in water.

Conventionally, a variety of devices are known with which wave profiles can be generated in water with a suitable for surfing wave slope. In the present case, the term "wave profile with a suitable wave surfing suitable for surfing" is to be interpreted broadly, including all constellations in which a slope-like section is formed with water, which can be surfaced by utilizing the gravitational force.This is the formation of a wave in the strict sense not necessary In the simplest case, the wave slope is simply formed by a water flow, which is pumped against the gravitational force up an inclined plane.

Systems for generating artificial wave profiles are known e.g. from WO 2010/054850 AI, US 2003/0180095 AI or WO 03/092460 AI known. In these systems, water is conveyed through a flow channel or through a tank in which a disruptive body is arranged, which is flowed by the water or flows around. The bluff body is designed so that it forms a wave profile in water.

The known systems have the disadvantage that a considerable energy input is required to promote the water through the flow channel or through the basin. This can be done by correspondingly powerful electric pumps, which feed the water directly into the flow channel. Alternatively, the water supply by providing suitable storage tank o. The like. Take place, which are also to be filled with appropriate electric pumps.

Furthermore, devices for generating wave profiles in natural streams are known, for. B. from DE 200 19 358 Ul. In such a device, an amount of water, which is naturally present in sufficient quantity, passed over a bluff body, whereby a result

desired water wave, z. B. a standing wave is generated. However, such a system is subject to the disadvantage of a large installation effort, so that a mobile use system is not possible.

The invention is based on the problem to provide an apparatus and a method for generating a wave profile in water, such that the wave generation is portable and with low energy use possible.

The above problem is solved by a device having the features of claim 1 and by a method having the features of claim 15. Advantageous developments of the invention are defined in the dependent claims.

Essential to the invention is the consideration that a wave profile is generated in a wave pool, which is located in a buoyant platform that floats in its operating state in a preferably natural waters. The platform and the wave pool formed therein are designed so that water from the waters surrounding the platform can flow into the wave pool and then flow back out of the wave pool back into the water. The inflow and outflow of the water into and out of the wave pool is ensured via an inlet opening and an outlet opening. The wave pool is thus preferably continuously flowed through by the water which originates from the surrounding waters. In the wave pool a Störkörperanordnung is provided, which forms a wave profile with a suitable for surfing wave slope in the water flow. The term "wave profile with a suitable for surfing wave slope" is to be interpreted broadly, as explained in the introductory part of the description.

The provision of a sufficient amount of water that is required for the flow through the wave pool, is unproblematic insofar as the platform is embedded with the wave pool located therein in a preferably natural water and from this the required water is obtained.

For the purposes of the invention, the 8ί0Λ0 6Γ3ηοΓ <_ ^ Ηη ^ is the wave generation. This means that the targeted in the wave pool 12 004986

- 3 -

the water is flowing and while the water is diverted or deflected, such that in the wave pool the desired wave profile is generated.

The proposed solution for the first time a device for generating a wave profile in water is realized, which is mobile by their buoyancy. Advantageously, the platform is designed in the manner of a pontoon, which may possibly even have a traction drive.

In a particularly preferred embodiment, the proposed device is used in a flowing body of water, which has a certain body of water. In this case, the arrangement according to claim 2 is such that at stationary fixed platform, the generated wave profile in any case partly due to the already existing water flow. This allows an additional use of energy by the use of pumps o. The like., Which may be required for the generation of the wave profile, reduce, and even completely eliminate in certain cases. Preferably, the wave profile in this sense is at least 40%, in particular at least 60%, generated by the stream of water.

Conveniently, the generated wave profile may have at least one standing wave, which is highly popular for recreational applications, in particular for surfing (claim 3).

In a further preferred embodiment, the bluff body assembly can be replaced and / or changed with respect to its inflow profile. As a result, the wave profile can be changed in the desired manner, for. B. in terms of its amplitude or in terms of a course of the wave within the wave pool.

A particularly advantageous embodiment of the invention results from the fact that the Störkörperanordnung is at least partially made of a flexible material. With a suitable design, the outer dimensions can then be changed without removal from the water, for example by inflation o. The like .. According to another variant, the Störkörperanordnung can be moved up or down in the wave pool. This means that the height of the arrangement of the bluff body arrangement in the wave basin is variable, whereby 12 004986

- 4 -

out a different flow of the Störkörperanordnung and thus result in a modified wave profile. In this way, a change in the contour of the Störkörperanordnung to produce a modified wave profile with inexpensive means and in particular in a short time is possible.

In particular, overturning waves can be easily realized that the Störkörperanordnung is formed on its inflow surface concave with respect to a main flow direction (claim 4).

In the further preferred embodiment according to claim 5, two bluff bodies are arranged in the wave pool, wherein the water flows through in the wave pool between these bluff bodies. Such a multi-part, in particular two-part, Störkörperanordnung has proven itself in practice.

Conveniently, the two bluff bodies can be attached or attached to opposite side edges of the wave pool. This leads to the advantage that the widest possible width of the wave pool for the purpose of surfacing o. The like. Is available and is not collected by the Störkörpern.

The inlet opening may be provided in a lower portion of the wave pool so that the water flows into the wave pool near its bottom surface. In other words, after leaving the inlet opening, the water flows directly onto the bottom surface of the wave pool without overflowing a step or the like, which would lead to undesirable turbulence in the flow. In the further preferred embodiment according to claim 6, the inlet opening opens below the water surface of the surrounding water in the wave pool. With a suitable design, the inflow of water into the wave pool is thereby promoted gravitationally.

Another measure for achieving a uniform flow within the wave pool is that the inlet opening is adapted with its width to a side edge of the wave pool, so that the inlet opening extends over the entire width of this side edge (claim 7). 12 004986

In the further preferred embodiment according to claim 8 upstream of the inlet opening is provided or preceded by a calming zone, by means of which the speed and the direction of the flow is made uniform. The calming zone is designed such that the water flows in via the inlet opening into the wave basin at the same speed and / or the same direction. The wave flow is preferably homogeneous over the entire inlet opening in terms of speed and direction. In this case, the water preferably enters the wave basin with a laminar flow without turbulence occurring.

The calming zone ensures that irregularities in the flow of water that can result from the natural waters outside the platform are leveled out in the same way. This can be realized, for example, in that the water flowing through is passed through nozzles or the like which bring about a corresponding homogenization of the water flow. Here and preferably, the calming zone comprises a baffle arrangement, with which the water is guided in the direction of the inlet opening.

According to the advantageous development according to claim 9, a regulation zone is provided upstream of the inlet opening, by means of which a water flow rate in the direction of the inlet opening of the wave basin can be regulated. This is particularly advantageous in the case of a strong natural flow, in order to reduce the water throughput through the regulation zone.

In the preferred embodiment according to claim 10 may be provided upstream of the inlet opening, a pumping device, through which water can be conveyed in the direction of the inlet opening of the wave pool. This is advantageous if the natural flow of the water to fill the wave pool is not sufficient. Thus, a use of the device in natural waters with little or possibly no water flow is possible. Conveniently, the pumping means may be arranged in the regulation zone, in view of a compact design of the device.

In the preferred embodiment according to claim 11, it is provided that the platform has an inlet chute leading to the inlet opening of the wave tank. T / EP2012 / 004986

- 6 -

Nal, which is further preferably upstream of the calming zone. Such an inlet channel allows the influence of the inflowing water in many ways, as will be explained.

An above-mentioned, naturally occurring stream of water flow can be optimally utilized for the purposes of this invention in that, according to the embodiment of claim 12, an inlet channel in the platform leading to the inlet opening of the wave basin, is formed funnel-shaped in the flow direction. Such inflow may be in both the vertical and horizontal directions. As a result, the flow cross-section is narrowed in the direction of the inlet opening, whereby the flow velocity is increased accordingly.

If an above pumping device is provided upstream of the emissive opening, the inlet channel formed inside the platform upstream of the pumping device may expediently be adapted with its cross-sectional width substantially to a diameter of the pumping device. More preferably, the inlet channel may have a uniform or constant cross-section and be cylindrical, so that the water that is sucked in the direction of the pumping device remains as free of turbulence as possible.

The device according to the proposal can advantageously be used as a sundeck, as a terrace or the like. In the preferred embodiment according to claim 13, it is such that the platform has on its surface in particular adjacent to the wave pool at least one tread area, which is at least accessible by a person. According to a further variant of claim 13, a particularly compact arrangement results from the fact that the above-mentioned tread area sweeps over at least part of the inlet channel and, preferably, that the tread area substantially sweeps over the inlet channel. The inlet channel thus runs under the tread area and causes no restriction on the extent of the tread area.

In a further preferred embodiment, congestion within the wave pool at the downstream end, ie in a basin area opposite to the inlet opening, is effectively prevented. For this purpose can itself EP2012 / 004986

- 7 -

extend the outlet opening over the entire width of a side edge of the wave pool, which is opposite to the inlet opening.

A further optimized delivery of the water out of the wave pool can be ensured by at least one flow support device with which the outlet opening communicates, preferably in such a way that this flow support device is a pumping device which is arranged inside the outlet opening. Depending on the amount of water that flows through the wave pool, two or more than two pumping devices may be provided, for. B. also in the region of the outlet opening. A particularly targeted discharge of water from the wave pool can be further achieved by the fact that the pumping device can be adjusted in the region of the outlet opening with respect to their position on the side edge of the wave pool. This is particularly advantageous when the wave profile generated in the wave pool is asymmetrical, with a main flow e.g. at the right portion of the side edge of the wave pool where the outlet opening is provided. Accordingly, in this case, the pumping means is also positioned in this right region of the side edge of the wave pool. If a different wave profile is produced when the arrangement of the at least one disruptive element within the wave pool changes and the flow impinges on another point of the side edge of the wave pool, the position of the pumping device in the region of the outlet opening can be suitably adapted thereto.

The above flow support device may also be formed by a suitable flow channel, which is formed, for example, on an underside of the buoyant platform and there flows through the natural flow of the surrounding water. If this flow channel has a flow cross-section which causes a venturi effect, it can be achieved by the fluid communication with the outlet opening of the wave pool that water is conveyed out without a supply of electrical energy from the wave pool in order to avoid unwanted congestion in the wave pool , Taking into account such a flow channel can be dispensed with a use of a pump in the region of the outlet opening of the wave pool, so that operation of the device is possible even without a supply of electrical energy. 6

According to another teaching according to claim 15, which has independent significance, a method for producing a wave profile in water is claimed. After this further doctrine floating in a water platform is provided with a wave pool therein, with water from the water is introduced into the wave pool and out of the wave pool out back into the water, so that the wave pool preferably continuously from the water of the water is flowed through.

It is essential that an arranged in the wave pool structure Störkörperanordnung is so flown with the water of the water that in the wave pool water flowing through a wave profile is generated with a suitable for surfing wave slope. As already explained, the term "wave profile with a surfel suitable for surfing" is to be understood widely, for example the wave profile may comprise a standing wave.

Advantageous developments of the inventive method will become apparent from the above developments of the device according to the invention, to which reference is made to avoid repetition.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. In the drawing shows:

1 is a simplified plan view of an inventive device (a) for a first type of possible wave profile, and (b) for a second type of possible wave profile,

2 is a plan view of an inventive device for generating wave profiles in water,

Fig. 3 is a longitudinal sectional view taken along the line A-A of Fig. 4, and

4 is a cross-sectional view taken along the line B-B of FIG. 3.

The device shown in the drawing is used to generate an artificial wave profile 1 in water and consists essentially of a platform 2, in which a wave pool 3 is formed. The platform 2 is buoyant and embedded in a natural body of water. In the two views a) and b) of Fig. 1, the platform 2 is in principle greatly simplified, each shown in a plan view. The arrow HS symbolizes a main flow direction, with which the platform 2 and in particular the wave pool 3 is traversed by water, in the drawing plane of Fig. 1 from left to right.

The view a) of Fig. 1 illustrates a variant of the device in which within the wave pool 3, a bluff body assembly 6 is arranged in the form of a survey, which may be attached to a bottom surface of the wave tank 3. If water flows through the wave pool 3 along the main flow direction HS, water is flowed over the bluff body arrangement 6 on its surface, from which a wave profile 1 forms above this. Essential for such a wave profile 1 is the fact that it has a wave slope 1a, which is preferably stationary with respect to an edge region of the wave pool 3. An amplitude of this wave slope la is sufficiently high, so that the wave slope la is suitable for surfing or surfing. The wave profile 1 according to the view a) of Fig. 1 goes back to a wave that does not overturn.

The view b) of Fig. 1 shows a further variant for generating a wave profile, in which the Störkörperanordnung 6 is formed on its inflow surface concave with respect to the main flow direction HS. As a result, the water overflows when the disturbing body arrangement 6 flows on, thereby forming a pronounced wave trough. Even with the resulting wave profile according to the view b) of Fig. 1, a characteristic wave slope la, which is very well suited for surfing or surfing. Conveniently, the inflow surface of the bluff body arrangement 6 can extend obliquely with respect to the main flow direction HS within the wave tank 3. This causes a lateral outflow of water from the inflow surface, which can overlap with the explained overturning of the shaft.

Hereinafter, a concrete embodiment of the device is explained in detail in FIGS. 4986

- 10 -

In Figs. 2 and 3, the device is shown in a plan view. Through an inlet opening 4 and an outlet opening 5, water from the surrounding water can flow into and out of the wave pool 3 (FIG. 3). The arranged in the wave pool 3 Störkörperanordnung 6 consists in detail of a first interfering body 6a and a second interfering body 6b, which are flowed in the wave pool 3 of water. Adjacent to the wave pool 3, the platform 2 has on its surface at least one tread area 7, which can be entered by at least one person. The carrying capacity of the platform 2 is preferably designed so that several people can stay on the tread area 7, without the platform 2 comes in an inclined position or even submerged.

The plan view of Fig. 2 illustrates that the two interfering bodies 6a, 6b of the interfering body assembly 6 are each attached to a longitudinal side edge 8 of the wave pool 3. Thus, the bluff bodies 6a, 6b face each other so that the water in the wave pool 3 can flow between the bluff bodies 6a, 6b. The bluff bodies 6a, 6b are targeted by the water, so that the result is a targeted wave profile 1 is generated with a suitable for surfing wave slope la. The wave slope 1a is shown very schematically in FIG. It may be pointed out that very different possibilities are conceivable to form a wave slope 1a from a water flow.

The wave pool 3 is formed closed down and has a corresponding bottom surface 9 (see detail view I of Fig. 4). The term "closed" is to be understood here broadly and includes, for example, a wave pool 3 with porous or latticed wall areas.

The bluff bodies 6a, 6b are here and preferably arranged in the wave basin 3 in such a way that they are in any case also fastened to the bottom surface 9. The detail of Fig. 3 illustrates that the inlet opening 4 opens at a front transverse side edge 10 of the wave pool 3, namely in a lower region thereof, in the wave pool 3. The width of this inlet opening 4 corresponds essentially to the width of the front transverse side edge 10 of the wave pool 3. T EP2012 / 004986

- 11 -

Upstream of the inlet opening 4, a calming zone 11 is arranged (FIGS. 3, 4). The calming zone 11 shows a baffle arrangement I Ia in such a way that there is no sharp-edged jump towards the inlet opening 4 and insofar a laminar water flow is ensured.

Within the platform 2, an inlet channel 13 is formed upstream of the calming zone 11 (FIG. 3). Through this inlet channel 13, water from the water surrounding the platform 2 can flow in the direction of the calming zone 11. A synopsis of the sectional views according to FIGS. 3 and 4 illustrates that the inlet channel 13 is funnel-shaped tapering, namely both in a plane substantially parallel to the water surface, as well as in a plane orthogonal to the water surface. This embodiment of the inlet channel 13 has the purpose of increasing the flow velocity of the water in the direction of the calming zone 11. Subsequently, the water flow in the calming zone 11 is harmonized such that the flow components of the water have both a substantially equal velocity and a substantially same direction and are free from turbulence.

To regulate a water flow, which results from a natural stream of water, a regulation zone 12 is provided, in particular the calming zone 11 upstream. In a variant, the regulation zone 12 is associated with a flap element 14, as can be seen in detail II of FIG. 4. The flap element 14 is adjustable by motor. By adjusting the flap element 14, a desired amount of water can be adjusted, which flows through the regulation zone 12 and then flows into the water basin 3 through the inlet opening 4. The flap member 14 satisfies e.g. the function to reduce an optionally too strong natural flow with respect to their water flow, so that as a result, a sufficient amount of water can flow into the wave pool 3. In this connection it should be pointed out that the inlet opening 4 is arranged below a water surface of the water surrounding the platform 2.

The device is suitable for use in a flowing body of water with a flow, wherein a fixed position of the platform 2 by suitable fastening means 2a, z. B. Taue o. The like., Is guaranteed, with which the platform P2012 / 004986

- 12 -

Form 2 is attached to the shore area. The natural body of water flow is usually sufficient to achieve a preferably continuous flow in the wave pool 3 of the platform 2. If the natural flow is too strong, the flow or volume of water that is passed through the wave pool 3 can be regulated by means of the illustrated flap element 14.

4 shows a further variant for the regulation zone 12. Hereinafter, a pump 15 is provided upstream of the inlet opening 4, through which water is conveyed into the wave pool 3. This pump 15 may be provided alternatively or in addition to the flap member 14. During operation of the pump 15, water from the upstream region, i. H. sucked in the inlet channel 13. The power level of the pump 15 can be variably adjusted to promote a different volume of water into the wave pool 3 as needed. The pump 15 is used when a natural body of water, in which the platform 2 is embedded, either has only a weak flow or possibly no flow at all.

At a front end face 2b of the platform 2, a filter device in the form of a sieve 16 is mounted, with which an influx of flotsam or similar debris from the water into the inlet channel 13 is effectively prevented. Fig. 3 illustrates that the screen 16, starting from a central axis M of the platform 2 in the direction of the respective side edges of the platform 2 extends obliquely. This causes an automatic sliding of foreign matter on the screen 16 to the side, so that a water flow for the inlet channel 13 is not clogged.

At a rear transverse side edge 17 of the wave tank 3, the outlet opening 5 is provided. In the same way as the inlet opening 4, the outlet opening 5 extends over the entire width of a rear transverse side edge 17 of the wave tank 3. The detailed view I of Fig. 4 illustrates that adjacent to the outlet opening 5, a pump 18 is provided, the water from the wave pool 3 promotes out. This is illustrated by the arrow S. By means of a holder 19, the pump 18 is positioned in the outlet opening 5, wherein the position of the pump 18 in the outlet opening 5 is variable along the rear transverse side edge 17, as explained in more detail below.

The operation of the device for generating an artificial wave profile 1 in water, i. within the wave pool 3 is provided as follows:

After the platform 2 has been let into a body of water, an inflow of water into the inlet channel 13, e.g. caused by the natural stream of water. In FIG. 2 and FIG. 3, this is indicated by the block arrow E in each case. If the natural body of water flow is insufficient to achieve a continuous flow of the wave pool 3, optionally the pump 15, which may be provided upstream of the inlet opening 4, can be put into operation. In this context, the term "continuous flow" is to be understood in terms of time, namely to the effect that the wave pool 3 is continuously traversed by water, without causing the water flow breaks off.

After flowing into the inlet channel 13, the water first passes through the regulation zone 12 into the calming zone 11, before it is subsequently introduced through the inlet opening 4 into the wave pool 3. The influx of water into the wave pool 3 is u. a. favors that the inlet opening 4 opens below a water surface of the water in the wave pool 3. As already explained above, the pump 15 preferably ensures sufficient flow in the wave pool 3 even in calm waters.

The platform 2 is traversed by the water in a main flow direction HS. The term "main flow direction HS" is understood here to mean a direction along which the water flows longitudinally through the platform 2. To this extent, for the exemplary embodiment according to FIGS. 2-4, this main flow direction HS is congruent with a longitudinal axis of the platform 2. After entering The water flows selectively into the wave pool 3, the two baffles 6a, 6b of the baffle arrangement 6, from which the flow pattern indicated in the drawing results The water then flows through the outlet opening 5 over the entire width of the rear transverse side edge 17, which is shown in FIG 3 is indicated by the block arrow. 4986

- 14 -

It may be noted with respect to the first obstruction body 6a that its inflow surface is concave with respect to the main flow direction HS and thus corresponds to the inflow surface of the obstruction assembly 6, which has been explained above with reference to the view b) of FIG. FIG. 2 further illustrates that the inflow surface of the first obstruction body 6a extends obliquely within the corrugation basin 3 with respect to the main flow direction HS. As a result, water which has formed at the inflow surface of the first interfering body 6a to form a roll-over shaft, as viewed in the direction of flow, is diverted to the right in the direction of the second disruptive body 6b. As a result, this results in a wave profile, preferably in the form of a so-called standing wave whose longitudinal extent extends obliquely within the wave pool 3. Such a standing wave follows the principle "water travels through the wave", wherein the characteristic wave slope 1a is substantially stationary relative to the wave pool 3. In the detail illustration I of FIG. 4, the wave profile which results from the overturning on the leading surface of the forms first flow body 6a, shown again in a sectional view.

In the example of FIG. 3, the flow from the two disturbing bodies 6 a, 6 b is directed in the direction of the right region of the rear transverse side edge 17 of the wave pool 3. The pump 18, which is provided in the outlet opening 5, in this case fulfills the function to request the water from the downstream part of the wave tank 3. As a result, an undesirable congestion in the downstream part of the wave pool 3 is prevented. The required by the pump 18 amount of water is indicated in Fig. 3 by the block arrow A ₂ . The capacity of the pump 18 is sufficiently large, so that a flow of accumulation in the downstream part of the wave pool 3 is prevented and thus the desired wave profile 1 is not impaired.

The efficiency of the pump 18 is further improved by the fact that its lateral position with respect to the rear transverse side edge 17 is adapted to the flow pattern which is generated by the two disruptive bodies 6 in the wave pool 3. In the example of the illustration of FIG. 2, the pump 18 is specifically arranged in the right region of the rear transverse side edge 17, because there the flow impinges after passing through the two disruptive bodies 6. T EP2012 / 004986

- 15 -

It should be noted that the number of the obstruction bodies 6a, 6b which can be arranged in the wave pool 3 and the shape thereof are not limited. Notwithstanding the representation in FIG. 2, either only one disruptive body 6 or more than two disruptive bodies 6 can be mounted in the wave pool 3. In this context, it is important that the lateral position of the pump 18 in the region of the outlet opening 5 at the rear transverse side edge 17 can be changed, namely in adaptation to a respective flow pattern within the wave tank 3. This ensures that the pump 18 is always there is positioned where the flow impinges on the rear transverse side edge 17 of the wave pool 3. In this regard, it is understood that two or more pumps 18 can be arranged side by side in the outlet opening 5 in order to ensure an even greater delivery rate out of the wave pool 3. In addition, a plurality of juxtaposed pumps advantageously occupy a greater width in the outlet opening 5 in order to prevent undesired stagnation flows in front of the outlet opening.

As explained above, the wave profile 1 can have at least one standing wave, which is suitable, for example, for surfing. However, any other wave profiles are possible, which are either adapted to leisure activities for people who are in the wave pool 3, or merely for purely optical purposes. An adaptation of the resulting wave profile 1 can be achieved by changing the flow rate of water passing through the wave pool 3, e.g. by a control of the flap element 14 and a control of the pump 15. Additionally or alternatively, it is also possible to use bluff bodies with a changed contour in the wave tank 3.

If, as explained above in the wave pool 3, a desired wave profile 1 has been generated by the wave pool 3 is continuously traversed by water, so a person can proceed from the tread area 7 of the platform 2 in the wave pool 3 to z. For beginners, it may be helpful that above the wave pool 3 (not shown in the drawing) bar facilities o. The like. Are provided, where the person can hold on while surfing , Such rod devices are suitably padded to a risk of injury excluded. In the same way, the tread areas of the Weüenbeckens 3 are suitably padded, but in any case created such that there are no sharp edges and thus a risk of injury is excluded.

It should again be pointed out that the device is optimized with regard to the energy which is necessary for the generation of an artificial wave. This is largely due to the fact that the inlet opening 4 opens into the wave pool 3 below a water surface of the surrounding water. If the platform 2 is in a flowing natural water with a sufficient flow, at least no pump is required for pumping water into the wave pool 3. Only the pump 18 in the outlet opening 5, and possibly the motor control of the flap element 14, require electrical energy. If optionally the pump 15 is provided, by means of which water is conveyed in the direction of the inlet opening 4, it is to be noted that the energy consumption of this pump is also moderate, because the water is only conveyed into the wave tank 3, but not to a higher level to pump is.

The proposed invention allows in a body of water at any location the production of an artificial wave profile 1. The anchoring of the platform 2 via the ropes 2a o. The like. At a bank area of the water body. Alternatively, the attachment of the platform 2 is also possible on a larger ship o. The like. Amidst a body of water. According to yet another alternative, it is also possible to drag the platform 2 - in the manner of a raft - in tow behind a ship. The necessary water flow through the wave tank 3 can be ensured here by the pump 15, with which the water is conveyed into the wave pool 3 inside. The device can be used both in stationary and in flowing waters and thus allows a variable use.
