- Fig. 6 shows a detailed view in longitudinal section of the compartment 20. It will be noted that four pumps 34 are arranged in the pumping zone 38. It can be seen further in FIG. 6 that the intermediate chamber 39 has a ceiling 37 which is designed as a water pipe 40.
- the water pipe 40 has two sections 44 and 46 which form an angle between them and which conduct the water in the device of evacuation 36 with the least loss of pressure and possible speed.
- the evacuation device 36 has the flow rectifier 84 which soothes the water and in particular creates a laminar flow. The water is directed inter alia by the flow rectifier 84 in the discharge direction 74 and conducted on the ramp 78 through the discharge opening 60.
- the blade 50 is disposed behind the discharge opening 60 the evacuation device 36 in the flow direction.
- Fig. 7 shows a cross-sectional view of the device 10 with a view of the
- the ramp 78 will be noted.
- the discharge opening 60 has a width 66 which corresponds substantially to the width of the blade 50 and to the width of the ramp 78.
- the water return channel 18 comprises three parallel partial channels. It is in particular provided that the walls 19 of the water return channel 18 support the ramp 78.
- Fig. 8 shows in isolation the blade 50 in longitudinal section through the device 10, the blade 50 having a downstream side 70 and an upstream side 71.
- the blade 50 also has a blade height 56 which is greater than the opening height 62 (see FIG 4) of the discharge opening 60, in particular to completely cover it.
- the blade height is 70 cm.
- the cutting edge 54 has a bevel 68 on the downstream side 70.
- the angle 73 of the cutting edge 54 with respect to the blade height 56 is about 45 °.
- the cutting edge 54, especially the bevel 68 is designed so that the angle 72 with respect to the flow direction 74 is about 45 °.
- Fig. 9 shows in detail another longitudinal section of the device 10 with the ramp 78 and the obstacle 100. Both the ramp 78 and the obstacle 100 is disposed in the wave pool 16.
- the ramp 78 is directly adjacent to the opening In particular, the evacuation wall forming the bottom 94 extends the ramp 78.
- the ramp 78 comprises a first water flow surface 104.
- the obstacle 100 comprises a second water flow surface 106.
- the ramp 78 and the obstacle 100 are adjacent to each other at the interface 102. It can be seen in FIG.
- the slope of the first water flow surface 104 of the ramp 78 is substantially identical to the slope of the second water flow surface 106 of the obstacle 100
- the obstacle 100 is designed in the form of a springboard and has in particular a curvature which descends to a point of inflection 107 which constitutes its lowest point and rises after the point of inflection 107.
- the obstacle 100 has a stall edge 108 which notably has a stub edge height 1 14 from the bottom of the wave zone 22 of about 25 cm.
- the obstacle has a deflector 1 10 which is associated with the stall edge 108.
- the deflector 1 10 may be provided, but is not essential. It can be adjusted to a variable angle 1 16 relative to a horizontal plane 1 1 7.
- the deflector 1 10 further has a length January 18 which is in particular about 20 cm.
- the angle 1 16 is preferably adjustable in the direction of flow above the horizontal plane 1 1 7.
- the height 1 1 2 of the obstacle 100 with the deflector 1 10, which has in particular a positive angle 1 16, that is, an angle 1 1 6 above the horizontal plane 1 1 7, is about 30 cm.
- Fig. 10 shows a schematic view of another compartment 20.
- the compartment has a ceiling 37 forming a water pipe 40 which has a curved section 46.
- the change of direction over an extent of the curved section 46 is therefore progressive.
- the water is driven with a change of flow direction progressively between a pumping chamber 38 and an evacuation device 36.
- the flow rectifier provides an accurate evacuation of water on the ramp.
- the accuracy, adjustment and aesthetics of the exhaust are further enhanced by the presence of the blade on the discharge opening.
- wave formation is improved by the presence of the ramp and the obstacle which have the same slope at the interface.
