Definitions
- the invention relates to a shaft system according to the preamble of claim 1.
- the shaft systems described here are not only suitable for mobile, but especially for stationary use with generally increased demands on operational safety.
- the wave surfing developed as a sport as well as a recreational activity, an increasing appeal to water and recreational athletes.
- the surfer uses the formation of waves in a liquid, which is typically water.
- the wave must therefore be suitable for carrying the surfer on a surfboard.
- these are so-called standing waves, ie essentially stationary wave crests.
- progressive waves can be used.
- the surfer can reach his position on the wave or wave crest.
- the surfer In the practice of his sport, the surfer is typically dependent on suitable conditions in natural moving waters, such as rivers or even the open sea, prevail, just allow the formation of appropriate waves in order to then use them for surfing.
- waves are either standing waves, such as in rivers or canals with barrages, obstacles or the like, or even running waves, such as in the open sea.
- At least one pump As a subsidy or possibly also by using a flow from an existing flowing water for a liquid flow in or through a wave pool.
- the liquid may flow from an inlet to an outlet of the wave pool.
- This ideally laminar flow of liquid can then, in particular due to a disturbance, form a substantially stationary wave crest on which the surfer can then surf with his surfboard.
- at least one wave exciter such as an unevenness, an edge, a guide element or the like, serves as a disturbance.
- An artificial wave plant which has a wave pool and a reservoir.
- the water used as liquid is pumped simultaneously by means of several serving as a conveyor pumps by separate conveyor lines directly from a storage tank and a sloping ramp in a wave pool in which a standing wave is excited by a guide. From the wave pool, the water then flows back into the reservoir.
- the disadvantage of this is in particular that in case of failure or shutdown already a pump, the flow in the wave pool is at least inhomogeneous or even turbulent. A failure of a conveyor therefore already puts the whole system down. In addition, no energy-saving operation by switching off individual funds is possible without considerable effort in driving and operation of the funds used is driven. It is therefore an object of the invention to eliminate the disadvantages described. In particular, the most cost-effective, reliable and energy-saving construction and operation of the shaft system should be ensured.
- This object is achieved by an artificial wave system with the features of claim 1.
- Such a wave system is provided for generating an artificial water wave for surfing. For this purpose, it has a reservoir (reservoir) and a wave pool.
- the basins can at least partially also be closed tanks.
- At least one conveying means in particular at least one pump, is provided for conveying liquid from the supply basin into the wave basin.
- the wave pool is formed by a liquid from an inlet to a Ausiass for forming a standing wave can be flowed through, wherein at least one arranged in the wave pool wave excitation element is provided.
- the shaft system according to the invention is characterized in that an intermediate basin is provided, which has a Ausiass, which is in flow communication with the inlet of the wave pool.
- the intermediate basin serves to receive the liquid conveyed by the at least one conveying means and to discharge into the wave basin. The liquid is thus promoted in particular by the wave pool in the intermediate basin to be discharged from there back into the wave pool.
- the at least one intermediate basin can be used as a buffer for the delivery of the liquid.
- the outflow of liquid through the Ausiass depends on the funding in particular practically only on the flow rate or the liquid level in the basin. It can thus be achieved a particularly uniform outflow.
- the intermediate basin is arranged fluidically between the reservoir and wave pool.
- the intermediate basin is arranged in the flow direction or conveying direction after the reservoir tank and before the waves basin, so in fact between these two.
- the spatial position of the pelvis may differ.
- the intermediate basin does not have to, but may be located spatially between the reservoir and the wave pool.
- a flow path is provided in the region between the outlet of the intermediate basin and the inlet of the wave basin. This can contribute to the reduction of turbulence as well as to the formation of a laminar flow.
- the flow path is further preferably formed at least in sections in the form of a preferably sloping surface or ramp.
- the flow path is further preferably formed at least partially adjustable in their inclination. Thus, the flow velocity can be varied at the flow path.
- discharge of liquid into the wave pool occurs just when a particular condition occurs.
- a discharge of liquid in the wave pool preferably a discharge of liquid in the wave pool.
- the liquid capacity of the intermediate basin is preferably smaller than that of the wave pool, but may also be similar or even larger.
- the intermediate basin can also be designed variably in size or capacity, for example by adjustable wall or floor elements. This can be done to adjust the amount of liquid contained in the pool or dispensed. An adjustment may also be provided for varying the fluid intake and / or fluid delivery during operation of the system.
- the at least one conveying means is arranged in the region of a fluidic connection between supply basin and intermediate basin.
- This makes it possible to directly convey the liquid from the storage tank into the intermediate tank.
- Further preferably acts it is in the fluidic connection to a breakthrough and / or pipe section, which is respectively arranged between the storage tank and the intermediate basin and this preferably connects to each other.
- a fluidic connection while a connection between two containers is considered, which is provided for the forwarding of liquid.
- each of the conveying means is arranged in or on a separate fluidic connection between the reservoir and the intermediate basin.
- a separate connection is provided for each conveyor.
- it can be a flow channel, such as a pipeline, a channel, a hose, a gutter, a basin or the like. So promotes each funding through its own fluidic connection, preferably its own flow channel.
- the flow channel preferably has a similar cross-section as the conveyor. Thus, an optimal, preferably laminar or turbulence-free promotion of the liquid can be achieved.
- the at least one conveying means preferably a plurality of the conveying means or all conveying means, is associated in each case with one or at least one reflow prevention means. This ensures that when the conveyor is deactivated no liquid can escape through the flow channel of the opposite to the conveying direction. This prevents the intermediate basin from emptying when individual conveyors are at a standstill.
- the backflow prevention means is designed in particular as a non-return valve, valve or the like. This allows a simple but reliable function, especially in a design as a non-return valve.
- the at least one backflow prevention means works in particular automatically, so it opens and / or closes preferably automatically.
- an alternative or additional manual and / or mechanical, in particular motor operation of the backflow prevention means may be provided, so a corresponding opening and / or closing.

- the outlet of the intermediate basin is in particular adjustable. The adjustability is preferably provided at least with respect to the cross section of the outlet and / or the liquid level in the intermediate basin.
- the discharged amount of liquid can be regulated, in particular with regard to the flow behavior.
- At least one adjusting means can be provided.
- This may in particular be a preferably adjustable and / or pivotable flap, ramp, gutter, a slide, a valve or the like.
- the adjustment can be done manually, but preferably by motor, in particular electrically, hydraulically, pneumatically or in another suitable manner.
- the outlet of the intermediate basin is designed as at least one overflow.
- at least one overflow edge is provided.
- the overflow is formed on or in the wall of the intermediate basin.
- An overflow ensures a trouble-free drainage of the liquid from the intermediate basin into the wave basin. In particular, thus, a laminar flow of the liquid can be achieved in the wave pool.
- the outlet of the intermediate basin is formed in a preferred embodiment of the invention as at least one breakthrough and / or pipe section.
- the outlet is located in a wall of the intermediate basin.
- the overflow may be adjustable, in particular height adjustable.

- Fig. 1 is a side sectional view of a Wellenaniage invention
- FIG. 1 the shaft system of FIG. 1 is in operation, FIG. 2
- Fig. 3 is a side detail view of a shaft system according to the invention
- Fig. 4 is a plan view of the area of the intermediate basin.
- FIG. 1 a Wellenaniage 10 is shown in a side, partial sectional view.
- 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.
- the guide device 12 is pivotable out of this recess in order to be able to excite a shaft 14.
- it may alternatively also be a wing-like or louvered construction of the guide device 12.
- the water 13 is conveyed in the illustrated embodiment by means of a pump 15 or feed pump as a subsidy from a main basin or storage tank 16 via a conveyor line 17 into the wave pool 1 1.
- a pump 15 or feed pump as a subsidy from a main basin or storage tank 16 via a conveyor line 17 into the wave pool 1 1.
- an intermediate basin 17 is present. This is mitteis the pump 15 filled with water 13 as a liquid.
- 16 pipe sections 18 are arranged in the lower region of the intermediate basin 17 as well as the reservoir. These pipe sections 18 serve as a fluidic connection between the tanks 16 and 17.
- the pumps 15 are arranged there.
- the pumps 15 are arranged with their pump rotors just inside the pipe sections 18. The pump rotors ideally fill the respective cross-section of the pipe sections 18 for a flow that is as laminar as possible. When operating the pumps 15, the water is pumped into the intermediate basin 17.
- the pumps 15 each shown here as an impeller are each arranged with a motor drive 19.
- the motor drive 19 is an electric motor.
- the pipe section 18 serves in this case as an inlet 20 for sucking water 13 into the intermediate basin 17.
- the inlet 20 is arranged for this purpose in the storage tank 16, usefully below the water level.
- a ramp 22 At the top of the drawing and then to the outlet 21 of the intermediate basin 17 is here still exemplified a ramp 22, through which the water 13 is passed into the actual wave pool 11. This ramp 22 may optionally be omitted. Because of the ramp 22 running down at a shallow angle, a flow of the liquid 13 which is accelerated but rather essentially laminar develops here.
- the laminar instead of turbulent flow is in particular due to the water 13 flowing out of the intermediate basin 17 instead of directly turbulently pumped water 13 reached.
- 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.
- FIGS. 1 and 2 an arrangement of the check valves 29 in front of the pumps in the pipe section 18 is shown by way of example.
- FIGS. 3 and 4 show, for the sake of completeness, exemplary arrangements of the check valves 29 in terms of flow, downstream of the pumps 15, that is to say in the intermediate basin 17.
- a controllable pump 15 By selective connection of pumps 15 and setting of intermediate values by a controllable pump 15 can be virtually any Flow rates set between zero and maximum power of all pumps 15.
- the pump power can also be controlled in addition, in particular continuously variable, but it does not have a sufficient number of independent pumps 15.
- the intermediate basin 17 serves to store and calm a lot of water 13 between.
- the effluent from the intermediate basin 17 via an overflow edge at the outlet 21 is practically almost always laminar, regardless of which and in which composition the pumps 15 operate.
- the shaft system 10 is initially shown at rest or in sleep mode. So here are the pumps 15 are not in operation, so that no water 13 is promoted. Consequently, no wave 14 can form in this case.
- the at least one pump 15 ensures that the water 13 is conveyed from the reservoir 16 into the wave pool 11.
- the reservoir tank 16 serves accordingly as a reservoir for the water 13.
- the conveyed into the wave pool 11 water 13 flows through this in the direction of the drain 23. There it flows down into the reservoir 16.
- the flow direction of the water 13 is indicated by arrows.
- the water level in the rest state of the wave system 10 is in the present embodiment, the water level here below the lower edge of the wave tank 11. Accordingly, the water 13 after switching off the pump 15 flows almost completely out of the wave pool 1 1 out. 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 again up to a certain minimum height.
- a certain amount of water 13 in the wave tank 1 1 available.
- this avoids, however, at the same time, that even when at rest, there is still a significant amount Water 13 is present in the wave pool 11, which may need to be monitored and possibly cleaned.
- the drain 23 may for this purpose also have a water level-dependent or height-dependent permeability. Thus, 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.
- 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 engine room 25.
- a cable 24 serves to supply the drive 19 with electrical energy.
- the cable 24 connects the drive 19 with a power supply 26 for the pump 15.
- the power supply 26 is disposed outside of the water 13.
- the drive 19 and the actual pump 15 are connected to each other in the usual way by a drive shaft 28. Serves here the drive shaft 28 for connecting the actual pump 15 with the separated drive 19 in a separate room 27. This is not shown here in detail implementation through the walls of the pump housing 17 as well as the space 25 required together with a corresponding storage and sealing.
