Definitions

  • the invention relates to an installation for the practice of aquatic activities.
  • the document US 4,539,719 describes an example of such a pool comprising at one end of the pool, a tank communicating with the pool floor, with a suction for sucking and storing in the tank a volume of water above the level of the pool. the pool water.
  • a valve makes it possible to expel the volume of water stored in the tank to the pool by gravity at high speed.
  • This device allows to produce in the pool a wave for surfing, similar to a natural wave, and with a depth of water corresponding to the depth of the pool.
  • the wave advances in the pool and the surfer's evolution is limited by the length of the pool.
  • creating a new wave requires some time to refill the tank.
  • documents US 5,236,280 and US 2006/026746 A1 describe another example of an installation for the practice of aquatic activities in which a sheet of water is forced to flow on a surface whose shape makes it possible to obtain the equivalent of a wave, which is perfectly stationary.
  • Various forms of surfaces under the water table make it possible to obtain different wave shapes, ranging from the continuous wave to a tunnel type wave.
  • the sheet of water used has a small thickness, which prohibits the use of means requiring a relatively large water depth, such as a finboard usually used at sea, and when the user If it falls, it may hit the solid surface without the surface's impact being effectively retarded by the water level.
  • the present invention aims to overcome the disadvantages of each of the two previous installations which until now seemed difficult to reconcile.
  • the invention relates to an installation for the practice of aquatic activities as specified in claim 1, and to a method for generating a stationary wave as specified in claim 10.
  • Preferred embodiments are specified in the dependent claims.
  • the shape of the deflector makes it possible to obtain a regular wave created downstream of the deflector in the basin without forming a roll.
  • This wave has a shape substantially identical to a natural wave.
  • the continuous feed means allow to obtain a stationary wave, without displacement in the basin, for a quick and easy learning of the practice of surfing.
  • the depth of water under the wave, in the basin allows the practice of surfing with fin surfboards, such as used at sea. Unlike the prior art, with such an installation it is possible to have any type of water activity, such as kayaking, canoeing, canoeing, surfing, or body surfing.
  • the deflector in the method of the invention, can be tilted 10 to 30 degrees to the horizontal and preferably 2.5 to 17.5 degrees to the horizontal.
  • the figure 1 is a top view of the aquatic activity facility 25 essentially comprising a pond 3 of substantially rectangular shape, a flow path 20 upstream of the basin 3, and supply means 12, 13, 14 in water of the flow path 20.
  • a large amount of water flows continuously in the feed path 20 from an upstream weir 1 to an upstream end 20a of the flow path 20 to a downstream end 20b of said flow path 20.
  • This continuous feed provides a stationary wave, without displacement in the pool, for easy access and quick learning of surfing.
  • the flow path has a deflector 7 through which the water in the basin 3.
  • Said basin 3 has a bottom 3a and side walls 3b, 3c, 3d, 3e including an upstream wall 3b and a downstream wall 3c.
  • the basin 3 has respectively a downstream weir 5 located behind the downstream wall 3c and side weirs 4 located behind the side walls 3d, 3e.
  • the downstream weir and the lateral weirs 4 are covered with safety grids 11 to prevent a user or a lost object from being sucked into the channels of the aquatic activity facility.
  • the figure 2 has a longitudinal sectional view of the installation, for viewing in profile the upper part of the installation with the flow path 20, the basin 3 and a curve 15 representing the surface of the water, and the part bottom of the installation including the water supply means.
  • the flow path 20 consists of a lower inclined section 2 on which the water flows and takes speed by gravity.
  • the inclined pan can be fixed or movable with an adjustable slope value of between 5 and 30%, in other words between 2.5 degrees and 17.5 degrees. In the latter case, a sealing device makes it possible to prevent any leakage of water with side guides 9 of the flow path 20.
  • the variation of the slope of the inclined plate 2 varies the speed and the energy of the the water in the flow path 20, which allows to vary the shape and height of the wave 15.
  • a baffle 7 making the full width of the flow path 20 is located at its downstream end 20b, while the water from the flow path 20 has taken a maximum speed.
  • the deflector 7 is articulated about a substantially horizontal axis and disposed transversely to the flow path 20, along the downstream end 20b, near the upstream wall 3b.
  • the inclination of the deflector 7 is adjustable by any means of mechanical actuation, hydraulic, pneumatic, electrical, or manual.
  • the deflector 7 may have a cross-section, as illustrated in FIG. figure 2 a rectilinear profile so as to initiate a particular movement and laminar with water from the flow path 20 to obtain a wave having a shape substantially identical to a natural wave, and without forming a roll.
  • a rectilinear profile so as to initiate a particular movement and laminar with water from the flow path 20 to obtain a wave having a shape substantially identical to a natural wave, and without forming a roll.
  • the deflector 7 may optionally consist of several sectors extending in the direction of its hinge axis, to give each sector different inclinations. In addition, each sector may have a different profile. However we prefer a deflector 7 formed of a single section to obtain a wave 15 the most regular possible over the entire width of the basin 3 allowing a user as a surfer to have broad evolution on said wave 15.
  • the deflector 7 has at its downstream end a trailing edge 7a extending into the basin 3, away from the bottom 3a of the basin, said deflector 7 being inclined upwards towards its trailing edge 7a.
  • the trailing edge 7a will be below the level of the water in the basin.
  • the water is accelerated by the flow path 20, is guided by the deflector 7 and meets the water of the basin 3, producing in said basin 3 downstream of the deflector 7 a wave 15 by the contribution of the water coming from the flow path 20 and the water already present in the basin 3 under the baffle 7 and downstream of the upstream side wall 3b of the basin.
  • the trailing edge 7a of the deflector 7 is located at a distance d of between 50 cm and 1 meter from the bottom 3a of the basin.
  • This water level located under the deflector 7 is important to create a large wave 15, implementing water movements producing a realistic wave shape and representative of what a user can find at sea or river .
  • lateral deflectors 8 may be integrated upstream of the deflector 7 and on each lateral side of the flow path 20 called guide 9, and to modify the shape of the wave 15 at its ends, so that by example a surfer can easily perform a U-turn.
  • the lateral deflectors 8 can be actuated by any means of mechanical, hydraulic, pneumatic, electric, or even manual actuation, from a complete erasure state to a state of projection in the flow path 20.
  • movable guide walls 18 are arranged and are each mounted to rotate in a vertical axis on each side of the deflector 7. When they are positioned in the extension of the guides 9, they limit the width of the wave 15. When they are in an open position with respect to the direction of the flow, they can modify the shape of the wave 15 and especially cause the creation of a second wave downstream Wave 15, useful for the practice of aquatic activities, such as canoeing or canoeing.
  • the opening of these movable guide walls can be increased until it is in a folded position, perpendicular to the extension of the guides 9 of the flow path 20.
  • Means 10 for regulating the water level in the basin 3 are arranged at the periphery thereof and limit lateral weirs 4 and downstream weir 5. They consist for example of flat valves or nozzles adjustable in height disposed at the upper end of the downstream wall 3c and optionally the side walls 3d and 3e. These means for regulating the water level make it possible to adjust the water level of the pool, so that it is above the trailing edge of the deflector 7, which is a paramount parameter for adjusting the shape characteristics. and height of the wave 15.
  • Each of these channels 12 is provided with a device for pumping 13 to force the water back into a water still and guiding device 14 allowing it to go up, in the upper part, upstream of the flow path 20, where is installed a mask 6 which allows to smooth the surface of the water entering the upstream weir 1 supplying the flow path 20.
  • Said mask 6 contributes to the formation of a smooth and smooth sheet of water in the flow path 20, making it possible to obtain a wave 15 itself regular and smooth.
  • Each of the pumping devices 13 of the side channels are located under the tracks 16 of the installation, as illustrated in FIG. figure 3 . Therefore, the presented facility uses all available space to circulate the water in a closed circuit, and the areas where the pumping devices 13 are located are ideally located to maximize the energy transferred to the circuit water. is giving it a big speed.
  • the invention may take the form of a fixed structure on the ground using any type of construction, or the shape of a mobile structure constructed in one or more elements.
  • the structure of the installation can be installed in a floating barge.
  • the facility for the practice of aquatic activities allows the regular practice of aquatic activities through the creation of at least one stationary wave similar to natural waves.
  • the water depth of the pool under the wave also allows for a variety of activities, such as fin surfing, free-style canoeing or rodeo.
