Definitions

  • the invention relates to a wave installation for generating waves in a pool or water tank, comprising a conduit connected, at least at both ends, via a hole in the wall of pool or tank to the pool or tank, piston means essentially closing off the cross-section of the conduit, and a power source in order to move the piston means backwards and forwards.
  • One of said methods comprises supplying compressed air in turn to chambers which are closed at the top and at the bottom protrude into the water in the pool or tank. If the compressed air is introduced into the various chambers at the natural frequency of the pool, this method requires relatively little energy, but the major drawback is that the tank or swimming pool has to have an adapted, relatively expensive design.
  • a ball which has a weight which is movable up and down therein floats in the middle of the tank.
  • a ball of this type takes up a relatively large amount of space and must be able to be suspended from the ceiling by a hoist construction.
  • a long electric cable to the ball is needed underwater, the length of said cable being subject to regulations. Further the ball is a heavy weight and may hurt people during movement.
  • DE-A-2811623 describes a swimming pool wherein a niche filled with water joins one of the sides of the swimming pool is in open communication with the swimming pool and is divided into three chambers by means of two partitions.
  • the two partitions are each connected by means of a rod to a piston which is movable in a hydraulic cylinder. Waves can be generated in the swimming pool by moving the two partitions by means of the pistons.
  • This construction requires expensive structural facilities and is not suitable for adding to an existing swimming pool as a recreation element in a simple manner.
  • the aim of the invention is to overcome the drawbacks of known wave installations and to provide a wave installation indicated in the preamble, for which the means for generating waves are simple and relatively inexpensive and can be installed in existing pools or tanks without special structural facilities (apart from possibly raising the hight of the walls of the pool or tank). Moreover, the wave facilities must not give rise to obstacles for swimmers and there must be no cables or leads present in the pool or tank.
  • the wave installation is characterized in that said conduit consists of one single pipe not belonging to the building structure of the pool or tank, and that said pipe is divided by one single piston into two flow chambers.
  • the length of the pipe corresponds to at most half of the resonance wave length of the water in the pool or tank.
  • each pipe will be provided on the other side of a central section, in which said piston is movable, with two or more channels connected to a hole in the wall of the swimming pool.
  • the cross-sectional area of the channels will have to be greatest at locations where the amplitude of the wave is greatest, and visa versa. Therefore, the cross-sectional area of the channels will be greatest at the ends of the pipe and that of the channels at the side of the means will be smallest and the cross-sectional area of the channels will decrease from the largest channel to the smallest channel.
  • the power sources will operate in phase with one another and adjacent pipes will have opposing directions of flow.
  • the walls of the wave pool or tank shown are indicated by 1.
  • Two wave installations each consisting of a pipe 2 having a central section 3 and two connecting sections 4 fitted on either side thereof, are installed on one side wall.
  • the connecting sections 4 each have three inlet and outlet channels 7a, 7b, 7c, which are connected by flange connections to openings 8a, 8b, 8c in the side wall of the pool or tank.
  • Figure 3 shows the flange connection between a channel 7a and the side wall of the pool or tank.
  • a pipe 9 is fixed by means of resin in the opening 8a to provide a seal.
  • Said pipe has a flange 10, which is fixed by means of bolts 11 to a flange 12 of the channel 7a.
  • the length of a pipe 2 corresponds to at most half the resonance wavelength of the pool or tank.
  • the two pipes shown generate waves which have twice a half resonance wavelength.
  • the one pipe operates in the same phase but in the reverse direction of flow to the preceding pipe.
  • the shape of the waves is shown by a broken line in Figure 2.
  • the channels 7a and the openings 8a at the ends of a pipe 2 have a larger cross-section than the channels 7b and openings 8b, which, in turn, have a larger cross-section than the channels 7c and openings 8c. Consequently, the size of the cross-section follows the size of the wave amplitude.
  • the first impulse will take a great deal of power, but as the wavelength of the generated wave follows the resonance wavelength of the pool or water tank, it becomes increasingly easier.
  • the installation according to the invention has considerable advantages. It is easy to install. No structural facilities are needed for wave generation. It may be necessary to raise the height of the sides of the pool or tank, or the water level could be lowered.
  • the apparatus can be fixed to the outside of existing pools or tanks by simply drilling a few holes in the wall of the pool or tank. The apparatus does not constitute any obstacles for the swimmer and there are no cables or leads through the area. It is very suitable for use in tanks containing mammals or fish and produces no noise.
