Definitions

  • the invention relates to a mobile or stationary usable artificial surfing system according to the preamble of patent claim 1.
  • Such a surfing system is known from US Pat. No. 6,019,547.
  • the water flows down a fixed inclined plane and meets successively below two solid flow-forming elements, which are spaced apart and produce a standing wave on a rising flank of the second element.
  • Fixed installations mean increased effort and can easily lead to injury in an arrangement in the surfing area in falls of Surfenden.
  • the object of the invention is to provide an artificial surfing system that generates a standing wave with simpler means and without such installations.
  • the generation of a standing wave takes place in that the inclined plane is connected in the form of a ramp at its upper end to a collecting space and its lower end is mounted in a wave basin.
  • the standing wave is generated in the surfing system according to the invention in that the water flowing rapidly down the ramp reaches a defined level Mass of relatively slow flowing water impinges in the wave pool and is thereby pushed up.
  • the collecting space from which the water flows to the upper end of the ramp a plurality of pump chambers are upstream.
  • the plenum is a large reservoir that homogenizes the amount of water delivered by the various pump chambers.
  • the pump chambers are separated from the plenum by a partition overflowed by the water whose upper edge is higher than the upper end of the ramp.
  • the height difference (Hi) between the upper edge of the partition and the upper end of the ramp by means of at least one adjusting mechanism is changeable.
  • the wave pool, the pump chambers and the collecting space are surrounded by a main pool.
  • the separation of the higher wave basin from the main basin also guarantees that only a defined mass of water - namely that in the wave pool - forms the resistance to the water flowing down from the ramp. The formation of a standing wave is thus much easier to calculate and more clearly reproducible.
  • each of the plurality of pump chambers is provided with one pump each, which suck water from the main basin and into the collecting space promote.
  • the delivery rate of the pumps can preferably be regulated to regulate the total amount of water conveyed to the collecting space and / or the several pumps can be switched on and off individually.
  • a buoyant body floating in the wave basin is arranged below the lower end of the ramp.
  • the free-floating lower end of the ramp can also be adjusted in height independently of the flow velocity on the ramp if required.
  • either differently sized buoyancy bodies can be attached for the trimming of the lower end of the ramp, or the buoyancy force of the buoyant body can preferably be regulated by a gas filling variable by means of a pump.
  • a device for influencing the flow is preferably arranged pivotably.
  • the device for influencing the flow and the wave shape in the wave basin at the lower end of the ramp is designed as a wing-like end profile.
  • a straight board which has an at least slightly increasing component with respect to the inclination in the lower region of the ramp is also sufficient.
  • This is preferably pivotally attached to the lower end of the ramp and optionally adjustable by means of an adjustment mechanism.
  • the end profile is not in the area of the surfaced by the surfers standing wave, but clearly upstream of it, so that fall-related injuries can not be caused by this component.
  • Another trim option is preferably formed in that the height of the upper bearing of the ramp can be adjusted by means of an adjusting mechanism. This adjustment is preferably made synchronously with an adjustment of the lower edge of an outlet opening from the collecting space, wherein the amount the inflowing over the upper end of the ramp water is adjustable by means of an adjacently defining a boundary wall of the collecting space in its height changing adjusting mechanism.
  • the water level in the wave basin can be regulated by an overflow which is preferably adjustable by means of an adjustment mechanism at the front wall downstream of the lower end of the ramp, from where the water flows back into the main basin.
  • Figure 1 is a schematic longitudinal section through the surfing system in the lateral region of the main basin according to the section line l-l in Fig. 2.
  • Fig. 2 is a plan view of the surfing facility
  • FIG. 3 shows a schematic longitudinal section through the surfing system in the lateral region of the main basin according to the section line I-I in FIG. 2.
  • the surfing system 10 shown in FIGS. 1 to 3 is formed by a trough-shaped main basin 20, which accommodates all other components and keeps the water required for the operation of the surfing system 10 in a closed circuit.
  • a wave basin 30 is arranged elevated on supports 32 opposite its bottom.
  • the wave pool 30, apart from the left-hand part of the main basin 20, extends over a large part of its length and width (see FIG. 2). However, it has due to the opposite of the main basin 20 raised bottom 31 to a much smaller depth.
  • the wave pool 30 is delimited on both sides by two side walls 30, on its right front side by a front wall 34 and on its left front side by a rear wall 35.
  • an overflow 36 is formed, via which Water from the wave pool 30 can flow back into the main basin 20 (see Figure 3).
  • the lower edge of the overflow 36 is adjustable by a double, relative to the front wall 34 by means of an adjustment 37 adjustable wall part in height, so that thereby the height of the water level in the wave pool 30 and thus the entire existing in the wave pool 30 body of water is variable.
  • a generally designated 40 water tower is arranged, which consists of three juxtaposed in the transverse direction pump chambers 41, 42 and 43 and a on the Width of all three pump chambers extending collecting space 46 composed.
  • a powerful volumetric pump 44 is arranged, which sucks water from the bottom portion of the main basin 20 and pushes up.
  • the pump chambers 41, 42 and 43 are separated from the plenum by a partition 45. The pumped by the pump 44 water passes through an overflow 47 above the partition wall 45 into the plenum 46 and is homogenized there to a large reservoir.
  • an outlet opening 48 is provided in the upper region.
  • a ramp 50 sloping downwards towards the wave pool 30 is mounted with an upper bearing 51.
  • the ramp 50 dives with its lower end 52 in the wave pool 30 a.
  • the lower end 52 is thus in the water of the wave pool 30.
  • a pivotable mounting of the ramp 50 in the upper bearing 51 and a floating mounting of the lower end 52 may be provided in the wave pool 30.
  • At least one additional buoyant body 54 is disposed on the underside of the ramp 50 near the lower end 52 thereof, preferably by means of a pump with a variable gas filling can be applied and thereby generates an additional variable buoyancy force, by means of which the lower end 52 is variable in its altitude or its pivot angle relative to the upper bearing 51.
  • an additional airfoil-like end profile 55 may be preferably pivotally mounted and changeable by means of an adjusting mechanism 56 in its pivoting angle.
  • the end profile 55 may be formed in its simplest form by a relative to the lower end 52 of the ramp 50 in the direction of flow slightly rising board.
  • the end profile 55 may be freely floating in the flow, fixed or mechanically adjustable in its angle with respect to the lower end 52 of the ramp 50.
  • Another possibility of influencing the amount of water and the flow velocity on the ramp 50 - and thus the shape and the size of the standing wave 60 - is the upper wall 51 of the ramp 50 facing rear wall of the collecting space 46 preferably together with the upper bearing 51st height adjustable to arrange.
  • Adjustment mechanism 53 for height adjustment of the upper bearing 51 is indicated as well as an adjustment mechanism 49 for height adjustment of a displaceable wall portion of the rear wall of the collecting space 46 in Figure 1.
  • a strainer 38 is arranged for safety reasons, to ensure that only water from the wave pool 30 flows back into the main basin 20 and no persons who are entrained due to a fall of the flow in the wave pool 30 or of these lost objects in the main basin 20 and thus in the intake of the pump 44 could be pulled.
  • the area to the right and left of the wave pool 30 and beyond the front wall 34 of the wave pool 30 can be walked on by webs 21.
  • the webs 21 are secured by railing 22 and accessible by stairs 23 at an end face of the main basin 20.
  • Wave pool 30 corresponding to the height of the lower edge of the overflow 36.
  • the pumps 44 start and very quickly promote water from the bottom of the main basin 20 via the overflow 47 of the pump chambers 41, 42 and 43 in the plenum 46th
  • the further pumped by the pump 44 water flows from the plenum 46 through the outlet opening 48 via the upper bearing 51 on the ramp 50 and shoots at high speed in a certain layer thickness to the lower end 52 of the ramp 50 down , At the lower end 52, this fast flowing water meets the relatively calm water in the wave pool 30.
  • the water flowing down the ramp 50 is shaped upwardly from the inert mass of the near-standing water in the wave pool 30 to a standing wave 60 , which sets in the wave pool 30 as a stationary state, and thus forms a surfable wave.
  • the water flows through the screen 38 via the overflow 36 back into the main basin 20 and is sucked in there again on the opposite end face of the main basin 20 of the pump 44.
  • the sieve 38 accommodating partition wall between wave pool 30 and main basin 20 is preferably formed inclined in the flow direction (not shown).
