Definitions

  • the invention relates to a method for stopping a partial collapse of an upward flow of the water, which is conducted upwards over a rising floor surface, as a result of an accumulation of water partial quantities braked by friction on boundary surfaces of a water sports device, and a water sports device for carrying out the method.
  • DE-C-17 03 746 describes a water sports device of this type which is particularly suitable for practicing gliding sports, such as surfing, water skiing, etc.
  • the water sports facility has a water tank in which the water is directed upwards over the rising floor at a flow speed that is greater than the fundamental wave speed, whereby the weight component of the athlete on the gliding device, which can be changed at an angle due to a shift in the center of gravity, has the opposite flow resistance is at least partially compensated. It is therefore also the hands-free, longer-lasting exercise of the sport types possible.
  • the water is preferably circulated in a circuit from a lower inflow nozzle over the rising floor surface upwards in a flowing flow and via an overflow provided along the upper edge and a return channel to the lower inflow nozzle.
  • a size 7 is formed.
  • Angle of inclination for example, wedge-shaped accumulations of decelerated water, and these partial quantities strive downwards due to their weight.
  • the amount of water flowing up is further increased by the wedge formation at the angle of inclination, thereby suffering a further loss of flow, as a result of which the slowed down amount of water increases again.
  • the invention has now set itself the task of improving the degree of utilization of the energy supplied in such a water sports device. This means that with unchangeable energy supply, an increase in the achievable water level, in particular an increase in the maximum angle of inclination, is possible, and if necessary but a reduced energy supply should also be necessary with unchanged level or maximum inclination angle.
  • At least those water partial elements in the boundary surface area that are braked by the friction are discharged from the upward flow and / or accelerated by supplying water at an increased flow rate to achieve this object.
  • Some of the braked water portions can be sucked off, accelerated, and returned to other water portions, for example by pumps.
  • a preferred water sports device for carrying out the method with a water tank with a rising floor area, in which water is directed upwards from an inflow nozzle along the lower edge of the floor area to an overflow along the upper edge of the floor area, is characterized in that the water tank at least in The areas of each boundary surface, in which the upward flowing subsets are braked by friction, have openings which form the mouths of drain pipes for the discharge of braked water subsets or inflow pipes for the supply of water with increased flow velocity to accelerate the braked water subsets.
  • FIG. 1 shows, according to the prior art, a water sports device in a vertical section (FIG. 1) and enlarged a section I (FIG. 2) and the section along the line III-III (FIG. 3).
  • FIG. 5 is also a section along the line V-V of FIG. 6.
  • Fig. 6 shows a plan view of a side wall area of an embodiment according to the invention
  • Fig. 7 shows a section along a line VII-VII of Fig. 6
  • Fig. 8 shows a section through a side wall-free embodiment, the right half being the rest or starting position and the left half shows the operating position.
  • FIGS. 1-3 A water sports device according to the prior art is shown in FIGS. 1-3.
  • a water tank 12 there is an obliquely upward, in particular concave, bottom surface 1, which is surrounded by two side walls 4 and an upper and a lower wall 16.
  • a mostly multi-part nozzle 2 extends through the lower edge of the base surface 1, through which water 3 is directed upwards in a flowing flow parallel to the side walls 4.
  • the water 3 flows over the overflow-side area 7 of the bottom surface 1 and a return channel 5 back to the nozzle 2.
  • the thickness of the water layer 3 over the rising bottom surface 1 increases from the bottom up to the overflow-side area 7, since the flow velocity V increases increasing altitude decreased.
  • Most of the kinetic energy of water is transformed into potential energy. To generate a circuit, therefore, only a relatively small amount of energy is required to compensate for the flow losses, which is introduced by one or more water screws 6.
  • This force therefore increases with increasing inclination of the ground due to an increasing weight component of the water subset 3 'and due to an increasing difference in depth h 2 -h 1 .
  • This is counteracted by the ever-decreasing thrust force which is exerted with the decreasing speed V and which is exerted by the main part of the water 3 on the partial water quantity 3 '.
  • the upper, steepest part of the concave bottom surface 1 can therefore have a wedge-like increase in the braked water portion, which is denoted by 3 ".
  • the thickness of the accumulated water portion 3" increases excessively as a result of backflow and increases the slope and the losses of the overlying flow of the Water 3 additional.
  • Fig. 3 shows that this premature breakdown of the circulating flow will begin in the vicinity of the side wall 4 in the edge region 8, since there is a larger, decelerated partial water quantity 3 "'. Furthermore, a partial water quantity 3""that can be supplied by the water sportsman to the Wall is sprayed and falls there, have a braking effect on the main part of the water 3. Maintaining the flow to a certain extent could only be achieved by increased energy supply, which would mainly increase the operating costs.
  • FIG. 4 shows an illustration corresponding to FIG. 2 of a detail I in a first embodiment according to the invention.
  • V out at least the most heavily braked by friction
  • Water subsets 3 ", 3"' is either derived or accelerated.
  • the formation of a water accumulation is prevented and thereby the formation of a wedge-shaped partial water quantity 3 "moving downwards, that is to say opposite to the direction of flow, is prevented.
  • the partial water quantities 3", 3 "' are preferably suctioned off through openings 13 which open the mouths of drain lines 14 in Form overflow area 7 of the bottom surface 1 or in the edge area 8.
  • the remaining partial water quantity 3 ' is small, so that it cannot cause any appreciable disturbance of the flow.
  • the drainage or suction of water is easily possible in these areas without impairing the usability, since it is mainly carried out in those areas where due to the reduced flow a greater depth existed anyway and the amount of water removed is 3 "small compared to the amount of water shooting up at speed V.
  • the angle of inclination of the floor surface 1 or its length and thus the achievable height is thereby increased without a substantial increase in the energy supply being necessary the suction power of the drain lines 14 is preferably also provided in a variable manner. With a constant inclination of the bottom surface 1, a lower drive power of the water screws 6 is required in order to maintain the circuit in comparison with the prior art.
  • a series of openings 13 is provided in the fillet 18 in the mouth region of a drain line 14, through which the water is drained, in particular suctioned off.
  • the fillet 18 is interrupted upstream. This interruption constitutes an opening 20 through which water from the inflow line 19 is introduced at an increased speed.
  • This accelerated water serves to accelerate the partial water quantity 3 "'(FIG. 3) which is braked in the edge region 8, which forms again after the discharge openings 13, and also to accelerate the temporarily occurring quantity of splash water 3"".
  • the water 3 becomes the water sports device in the circuit out, it is preferably provided, as indicated in FIG. 8, that the water discharged through the openings 13 and the drain lines 14 provided with valves 15 is fed back into the return channel 5.
  • a drain line 14 can be reintroduced at other points, for example upstream, at an increased speed to accelerate the amounts of water via the feed line 19 (FIG. 6).
  • a common line 21 is therefore provided between the openings 13 and 20, into which a pump 17, for example that of the filter system, is inserted, as is often prescribed for water purification in water sports facilities.
  • the embodiment according to FIG. 8 is opposite the state 1 has yet another special feature.
  • the water tank 12 is round or polygonal, the inclined bottom surface 1 being ring-like. It represents the outer surface of a truncated cone or truncated pyramid, the generatrix preferably being concave.
  • partial amounts of water 3 "', 3"" are avoided from the outset without removal or acceleration by virtue of the fact that the bottom surfaces do not limit any side walls 4 extending parallel to the direction of flow
  • the bottom surface 1 can already be more inclined with the same energy supply than in a water container delimited by side walls according to FIG.
  • a raised tank 11 is provided centrally, which serves to start the flow (right half of FIG. 8).
  • the peripheral nozzle 2 ' is closed, the elevated tank to level n 2 , and the return channel 5 filled with water 3.
  • the latter was previously sucked through the bottom openings 22 by means of the pump 17 into the elevated tank 11.
  • a film or flap 10 bears against the grate 9 from behind, as a result of which the elevated container 11 is essentially leak-proof.
  • the nozzle 2 With the water screw 6 running, the nozzle 2 is now opened quickly, so that the water 3 is shot up.
  • the films 10 also allow the passage onto the grate 9, since the total pressure of the water initially shooting up corresponds approximately to the level n 2 , but the water level in the elevated tank 11 has meanwhile almost dropped to the level n 1 .
  • the partial amounts of water 3 ′′ braked by the friction are then partially sucked off through the openings 13, which, for example, form an annular gap, and are fed into the return channel 5 via the now open lines 14.
  • the pump 17 can be a water jet pump or can be replaced by an even simpler barometric downpipe.
  • the outlay on equipment for implementing the invention is therefore preferably low, since the pump device is either that of the obligatory water purification or is distinguished by great simplicity.
