Description

[0001] Divisional application

[0002] This application is a divisional application of the Chinese invention patent application with application number 2022800308195, filing date February 25, 2022, entitled “Chamber, control system and method for generating waves”.

[0003] CROSS-REFERENCE TO RELATED APPLICATIONS

[0004] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 153,923, filed on February 25, 2021. Background Art

[0005] Water rides bring multi-generational fun to different groups of people in different geographic locations. Water rides allow people in different geographic locations to get simulated experiences from other locations. For example, a wave pool can simulate the experience of a beach.

[0006] Various water rides can be used to simulate natural environments to allow users to experience sports and activities from these other environments. For example, sheet surfing devices simulate the experience of surfing or bodyboarding, which allows surfers to surf with their bodies or a sheet of water formed by the contours of the underlying surfing surface. Sheet surfing does not provide a realistic surfing experience because the sheet of water does not allow for wave breaking or the use of a real surfboard.

[0007] The present application provides a deep water wave surfing system that attempts to create a surfing experience in a more accurately simulated natural environment. U.S. Patent Nos. (USPN) 8,434,966; USPN 9,103,133; USPN 9,279,263; USPN 10,145,135; USPN 10,280,640; and USPN 10,526,806 disclose deep water wave surfing simulators, each of which is incorporated herein by reference in its entirety.

[0008] Deep water wave surfing devices present unique challenges in managing the large volumes of water used in the surfing device. For example, currents and eddies may form to disrupt wave formation. Managing the air and water in and out of the chamber is also problematic. The air in the chamber can act like a spring, and the momentum of the water leaving and returning to the chamber can create undesirable forces and oscillations and other motions on the water. These forces may in turn create undesirable wave effects, turbulence, and other adverse characteristics within the waves generated. Summary of the invention

[0009] The invention discloses a pool wave generator, which has a pool area and a plurality of chambers for generating waves in the pool area. The plurality of chambers can be used to store or release water into the pool to generate desired waves.

[0010] Exemplary embodiments described herein may include unique pool and chamber configurations for managing fluid flows, including water and air within a chamber, to affect desired wave morphology and control or minimize undesirable wave effects. Exemplary embodiments of the systems and methods described herein may be used to control various features of waves, such as water level height in a chamber, which may be used to suppress residual waves after waves are generated in a pool. Such exemplary configurations may be used to generate and maintain desired wave formations and allow for repeated wave formations, either continuously along the length of a pool, or in a timely manner with desired time interfaces, such as repeated over the length of time between waves. Exemplary embodiments may also be used to control and define customized waves, which may have controllable or programmable individual features.

[0011] Although deep water wave pools with specific features are described herein, including the shape of the pool, the chambers for releasing water, and the troughs for controlling the return of water to the pool, these embodiments are exemplary only. Exemplary embodiments of the chambers and control systems and methods for generating waves can be used in different water environments. For example, the embodiments described herein can be used to generate waves for surfing, or just for wave pools. Exemplary embodiments can be used in other water surfing devices where water is stored and released in a controlled manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following detailed description illustrates the principles of the present invention by way of example and not limitation. This specification will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, modifications, variations, substitutions and uses of the invention, including what is currently believed to be the best mode for carrying out the invention. It should be understood that the drawings are general and schematic representations of exemplary embodiments of the invention, and do not limit the invention and are not necessarily drawn to scale.

[0034] Exemplary embodiments described herein include a pool configured to generate waves. The pool may include one or more chambers at one or more ends configured to receive and release water into the pool to generate waves. Exemplary chambers are provided to reduce turbulence, customize the time between waves, and generate better waves. The pool may be configured to generate different areas. To define or generate waves of different profiles, or to be used by individuals of different experience levels. The pool may also be configured as a floor construction or include additional water features, such as lagoons and channels for controlling water flow to dissipate wave energy and control water flow.

[0035] Although embodiments of the present invention may be described and illustrated herein in terms of pool wave generators having unique and novel features, it should be understood that embodiments of the present invention do not require or necessarily include every feature. The present disclosure does not require any particular component, configuration, or feature, and any combination of features may be incorporated or combined and remain within the complete description of the present invention. For example, including an elongated chamber between the chamber and the pool to reduce eddies may be used in any conventional feature of a pool wave generator. Similarly, including a spectator area or bottom contour to generate different wave zones may similarly be used alone or in combination with other features described herein.

[0036] Figure 1A An exemplary wave pool according to an embodiment of the present invention is shown. An exemplary pool wave generator 10 may include a pool area 12 and one or more chambers 14 for generating waves within the pool area. Waves 16 may propagate away from chambers 14 and toward a terminal end 18 of the pool.

[0037] In an exemplary embodiment, the pool area 12 may be a concave pool configured to hold water. The terminal 18 may be a wall for holding water. The wall may be vertical or may be inclined. In an exemplary embodiment, the terminal is formed by an inclined bottom of the pool to simulate or resemble a beach area. When water is pushed through the pool area 12 by releasing water from the chamber 14, the water may travel toward the terminal 18 and travel through and up the inclined bottom until the water stops and eventually returns to the pool area along the inclined bottom under the influence of gravity.

[0038] Figure 1A An exemplary pool wave generator is shown including two sides where waves can propagate from a chamber to opposite ends of the pool. Figure 1A The view in is depicted as looking down into the pool from above. The pool wave generator of this embodiment can be used to generate different zones that can have similar or different wave profiles for use by different surfers. The different zones can be used to create waves for surfers or participants with different experience levels. Exemplary embodiments include a pool wave generator in which waves propagate in a single direction, such as Figure 1B as shown in .

[0039] As shown in the arrow of adjacent chamber 14, chamber 14 can release water into the pool area 12 sequentially. Chamber can be aligned linearly along one side of the pool. Chamber can also include different directions, configurations and orientations. Releasing water from the chamber can be used to control wave properties, such as time intervals between wave height, direction, shape, waves, etc. As shown in the figure, the chamber in the middle of multiple chambers is released together, and then the chamber can be released outwards in order, thereby moving outwards towards the opposite end of multiple chambers. Chamber can also be configured to release in different directions or in different sequences, such as from one end to the other end or from the opposite end towards the middle of multiple chambers.

[0040] Figure 1A An exemplary embodiment is shown in which a linear array of chambers is provided along one edge of a pool area 12. The chambers may traverse a portion or the entire length of the pool edge. As shown, extending directly from the end of the last chamber on the pool edge, the lateral sides of the pool wall 19 may extend at a non-zero angle, the angle being measured from the linear extension of the pool edge defined by the chambers. In other words, the sidewall may extend directly forward from the end of the chamber. The sidewall may also have a component extending outwardly on a continuous extension of the chamber linear direction, thereby forming a non-zero, non-perpendicular angle with the linear extension of the pool edge including the chambers. Angling the pool wall may reduce the amount of water required to fill the pool and reduce the pool area where less than ideal wave action may occur.

[0041] Figure 2A-2CAn exemplary wave generation chamber and its associated controls are shown for generating waves in a wave pool as described herein. The chamber 20 may be configured to hold water at a chamber water level 28, and when water is released into the pool, the pool water level 26 increases to generate waves 26' that propagate across the pool away from the chamber 20. The chamber may include one or more valves 22, 23, 24 for controlling the holding and release of water in the chamber. In an exemplary embodiment, a first valve 22 may control the flow of water into and out of the chamber 20. In an exemplary embodiment, a second valve or valves may control the flow of air or fluid into and out of the chamber 20. As shown in FIG. Figure 2A-2C As shown, an exemplary inlet valve 24 may be used to introduce pressurized gas into the chamber. An exemplary exhaust valve 23 may be used to remove gas from the chamber by exhausting the gas or applying negative pressure to the chamber.

[0042] In an exemplary embodiment, the wave generating system may include a control system. The control system may include a sensor in the chamber. The sensor may include one or more sensors. In an exemplary embodiment, the sensor may include a water level sensor, a pressure sensor, or a temperature sensor. In an exemplary embodiment, the water level sensor may be used to determine or simulate the water level in the chamber. In another embodiment, the pressure sensor may be used to determine or simulate the water level in the chamber. Other control sensors may be combined, such as in the plenum, at the exhaust port, at the intake valve or intake valve actuator, at the pressure blower or at the blower motor, or at the control panel that controls the blower motor. Any combination of sensors may be configured as inputs to the control system to help operate or control the chamber. In an exemplary embodiment, the control system is configured to receive inputs from one or more sensors and control one or more valves in response to the received sensor inputs.

[0043] In an exemplary embodiment, the control system may include an actuator for setting the position of one or both of the valves 23, 24 to transition the valve from fully open to fully closed, or any intermediate position between fully open and fully closed. For example, if fully closed is considered to be zero degrees and fully open is considered to be ninety degrees, the valve can be positioned at any angle from 0 to 90 degrees. In an exemplary embodiment, one or both of the intake valve and the exhaust valve are equipped with a position controller so that one or more valves can be opened to any position from fully open to fully closed, and any position between fully open and fully closed.

[0044] In an exemplary embodiment, the height of the water level in the chamber can be measured using one or more sensors in the chamber. In an exemplary embodiment, the sensor is positioned at the top of the chamber. In an exemplary embodiment, the sensor is configured to provide an input to a control system so that the control system can determine the height of the water level in the chamber. The control system can be configured to control an exhaust valve or an intake valve to control the desired water level in the chamber.

[0045] In an exemplary embodiment, the chamber includes a pressure sensor. The control system can be configured to control the exhaust valve and the intake valve to maintain a desired pressure within the chamber. In an exemplary embodiment, the pressure sensor within the chamber can be in fluid communication with the chamber.

[0046] Exemplary embodiments described herein may include a control system capable of setting the position of one or more valves to fully open and fully closed.The control system may be configured to control the corresponding wave height by controlling a variable frequency drive (VFD) to achieve a desired pressure.

[0047] Exemplary embodiments described herein may include a control system capable of setting the position of one or more valves from any position from fully open to fully closed and any intermediate position therebetween. Exemplary embodiments include positioning one or more valves in intermediate positions between fully open and fully closed. The control system may be configured to control the corresponding wave height via a height set point rather than a VFD frequency.

[0048] like Figure 2A As shown, the system may have been released so that there is no water in the chamber 20 or the water level 28 in the chamber is at a low level (e.g. Figure 2C 23 can be opened to exhaust air from the chamber. The chamber 20 can be configured to evacuate air from the chamber 20 so that the chamber is negatively pressurized. The second valve 23 can also be opened so that the chamber 20 is at a neutral pressure and the air in the chamber is allowed to exhaust when the chamber is filled with water. The first valve 22 is opened and water is rushed into the chamber to raise the water level in the chamber.

[0049] like Figure 2B As shown, the first valve 22 is closed to maintain the chamber water level 28 above the pool water level 26. The chamber is then filled with pressurized gas to apply additional pressure to the water in the chamber. The second valve 23 is then closed and the first valve is then opened.

[0050] like Figure 2C As shown, the pressurized air in the chamber pushes the water level 28 in the chamber, which in turn causes the water to surge out of the chamber to create waves 26' that propagate across the pool. The first valve 22 may be closed and the air in the chamber exhausted, for example through the second valve 23.

[0051] The first valve 22 may be closed to limit the amount of water returning to the chamber, thereby minimizing disruption to the forming wave 26'.

[0052] The first valve 22 may also remain open to allow water to return to the chamber, and as with Figure 2B Closed as discussed.

[0053] In an exemplary embodiment, the control system can be configured to control a second valve 24 for providing air into the chamber and a third valve 23 for removing air from the chamber. The system can also include one or more sensors used as inputs to the control system for determining the height of the water level in the chamber or the air pressure in the chamber or the air pressure in a portion of the system in fluid communication with the chamber. In an exemplary embodiment, the control system includes a feedback loop so that the second valve 23 and the third valve 24 are positioned to control the height of the water level in the chamber and / or maintain a desired pressure in the chamber.

[0054] Exemplary embodiments may include a user interface, wherein the control system may be programmed. The user interface may be configured to display information to a user and may receive input from a user. The user interface may be used to provide settings for the control system, such as when determining the desired relationship between the position of a valve and a sensor input. In an exemplary embodiment, the user interface is configured to receive from a user desired water height profile information describing desired wave characteristics, such as a water height profile in a chamber, wherein the system is thereafter configured to determine control parameters in order to achieve the desired wave characteristics. Thus, exemplary embodiments of the control system may be used to control wave height during wave generation. Exemplary embodiments of the control system may be used to control wave shape, wave characteristics, and the like. The system may be used to generate unique and fully customized waves, as each chamber may be fully actuated to produce a combined effect with the water, thereby constructing almost any wave.

[0055] In an exemplary embodiment, the system is configured to cycle through the process of releasing water from the chamber and allowing the water to surge back into the chamber. The system may also include a delay after any number of cycles to allow the water in the pool to settle and reduce turbulence that may affect wave generation.

[0056] In the exemplary embodiment provided, three valves are shown, a first valve 22 for water control, a second valve 23 and a third valve 24 for gas control. Any combination of valves can be used and are within the scope of the present disclosure. For example, multiple gas valves can be used to vent the chamber, inject pressurized gas, etc., and multiple fluid valves can be used to release or keep water in the chamber. The order and cycle of the valves described here are merely exemplary. Any number of different ways can be used to release waves using valves, gates or other methods. The valves can be opened and closed in different ways. For example, the system can use a cleaning system to remove gas from the chamber before the water surges back, thereby raising the water level returned to the chamber. For example, the system can drain water into the pool without using a pressurized gas system. For example, a one-way valve can be used so that the valve does not need to be actuated separately to open and close. The valves of each chamber can be controlled individually or in sequence as part of a larger operation of the entire pool system.

[0057] Exemplary embodiments of the control system described herein can be used to control power consumption or reduce the power consumption required to generate waves of the same size. Lower power consumption can be achieved because no additional energy has to be consumed by suppressing the residual waves generated by the water oscillations in the chamber. Exemplary embodiments of the control system described herein can be used to control the generation (or reduction) of water flow in a pool. The exemplary embodiments described herein can result in more efficient operation of a wave pool and also extend the useful life of the equipment.

[0058] Figure 3 An exemplary wave pool 30 is shown for generating different areas with different wave characteristics in accordance with an embodiment of the present invention. In an exemplary embodiment, a pool profile 32 and pool floor 34 may be contoured to define a desired wave profile and create multiple wave zones 36, 37, 38.

[0059] In an exemplary embodiment, multiple wave zones 36, 37, 38 may be created. The creation of multiple wave zones may result from a single wave generation cycle of chambers. For example, chambers may be released in sequence to form a first wave. The first wave may change profile, height, direction, etc. The wave may also deteriorate or reshape based on the underlying topography of the pool floor. As shown, on one side of the pool, three wave zones are generated for a single wave generation cycle. The pool may have a mirrored configuration so that the entire pool has six wave zones. However, three of the wave zones are independent of the other three wave zones because the waves or portions of the waves that generate the first three wave zones are different from the waves or other portions of the waves that generate the second three wave zones. Any combination of wave zones may be generated, and the combination of two sides of three zones for a total of six zones is merely illustrative. In an exemplary embodiment, the wave pool may have one, two, three or more wave zones. The pool may have a mirrored configuration, such as Figure 1AThe structure in the embodiment of FIG. 1 can double the wave zone, or the pool can be as follows Figure 1B Opposite sides of the pool may also be configured differently so that different wave zones can be created across the entire pool.

[0060] As shown, the first wave zone 36 is adjacent to the wave generating chamber. The waves in this section are the highest. This area can be for the most experienced surfers. It can also be used for short board surfers.

[0061] As shown, after the wave leaves the chamber, the second wave zone 37 may be located in an area of ​​the pool that extends along the sidewall or edge of the pool. After the wave propagates out of the chamber, the wave will dissipate energy and lose height. Thus, this area is created for intermediate surfers and longboarders.

[0062] As shown, the third wave zone 38 may be adjacent to a side of the pool away from the chamber. This edge may correspond to the bank area 46' of the pool. This area may have a shallow depth and may have an inclined floor bottom. The first wave zone 36 may be used by surfers who are just beginning to learn about waves. This area may also be used for bodyboards, foam boards, kayaks or surfboards. This area may also be used for body surfing or wave jumping.

[0063] The pool floor may have regions corresponding to or influencing wave zones. For example, a first region 42' of the pool floor may generally correspond to the first wave zone 36, while a second region 44' of the pool floor may generally correspond to the second wave segment 37, and a third region 46' of the pool floor may generally correspond to the third wave zone 38. The fourth region 48' and other regions may be used to create and separate different wave zones and to shape waves as they propagate from the chamber. The different regions of the pool floor will be referred to as Figure 4 Have a fuller discussion.

[0064] Different floor bottom areas can be used to influence the wave profile. For example, the depth of the floor can affect the wave size, and the tilt of the floor can affect the wave shape, so the first area 42' adjacent to the chamber can generate a wave zone 36 for the most experienced surfers. This area can be about 2-6 meters deep. Therefore, this area can have a floor bottom with a larger tilt or tilt toward the opposite side of the pool shore or pool edge, or can have the greatest depth. The third area 46' can be adjacent to the short side or edge of the pool and away from the chamber, and can generate a wave zone 38 for the least experienced surfers. Therefore, this area can have a floor bottom with the smallest tilt or tilt toward the edge, or can have the shallowest depth. A gentler tilt can make the wave braking softer.

[0065] In an exemplary embodiment, the edge of the pool away from the chambers can also be contoured to affect wave characteristics. For example, in the area of ​​the third wave zone, or in the beginner's area, the edge can be raised toward the middle of the pool, on the side of the pool opposite the middle chamber of the chamber sequence. This high ground can form a shore or dry impression on the side of the pool. When the waves propagate through the pool from the chamber toward the shore, the waves can extend around the high ground into the pool area. Other or additional high ground can be set along the short section to create additional wave zones. In an exemplary embodiment, the high ground can be used to separate or redirect waves.

[0066] As shown, the chamber can release water sequentially into the pool, thereby generating waves. If the chamber is first opened in the middle of the chamber sequence, and then opened sequentially in the opposite direction toward each end, the left and right waves will propagate from the chamber and break almost simultaneously. The chamber sequence can also be delayed or offset so that the left and right breaking waves can be staggered. The expert wave zone can be defined as an area adjacent to or close to the chamber. The waves in the expert wave zone can break along the wave generation wall. Since the continuous release of water from the chamber can be used to keep the wave formation, the wave can maintain an approximately constant height. In an exemplary embodiment, the wave height in the expert wave zone can be about 1.5 to 3.5 meters. After the wave leaves the area close to the chamber, the wave will dissipate energy, and the wave height will decrease. The wave extending away from the chamber along the side edge of the pool can form a medium wave zone, and its wave height decreases from the expert wave zone. In an exemplary embodiment, the wave height in the medium wave zone can be about 1-2 meters. When the wave leaves the chamber, the wave height can continue to decrease. The wave can then break along the opposite side of the pool in the shallow water zone to create a larger wave zone. In an exemplary embodiment, the wave height in the beginner wave zone can be approximately 0-1.5 meters.

[0067] Figure 4 Shown with Figure 3 Exemplary bottom profiles corresponding to different wave zones of the pool wave system 40 described in FIG. Figure 5A yes Figure 4 Exemplary bottom cross-section view with reference line 50 . Figure 5B Shown along Figure 5A A cross-sectional perspective view of reference line 50 in FIG. 5 is provided to illustrate the pool floor. As shown, the bottom profile may include at least three regions.

[0068] In an exemplary embodiment, the first region 42 may correspond to a region adjacent to the chamber 14. Figure 5BAs shown, the pool floor 52 of the area may include a gradual upward slope so that the pool adjacent to the chamber is deeper than the pool on the side of the area 42 opposite the chamber. The slope may move from deeper to shallower across the area away from the chamber at an angle α. The first area 42 may be generally rectangular and as shown Figure 4 The first region 42 may also flare outwardly at the end so that the region traverses the front of the chamber and extends outwardly beyond the end of the chamber as the region tilts away from the chamber, as shown. Figure 3 Other shapes of the region are also conceivable.

[0069] In an exemplary embodiment, the third area 46 may correspond to an area on the end of the pool opposite to the chamber 14. The third area 46 may be on one side of the pool, corresponding to the end of the wave travel opposite to the starting point of the wave. The pool floor 56 of this area may have a gradual inclination that is gentler than the inclination of the area adjacent to the chamber. The pool floor 56 may include a gradual inclination upward so that the pool is deeper toward the first area 42 than the area on the opposite side thereof. The terminal of this area may have a zero depth so that the water washes the side to the surface. This area may simulate a beach area. The inclination may traverse the area from deeper to shallower at an angle β in the direction away from the chamber. This area may correspond to a band or width at the terminal of the wave on one side of the pool opposite to the chamber. Since the chamber may generate waves that propagate away from the chamber at an oblique angle rather than directly perpendicular to the chamber, the opposite end of the pool may be offset and include a portion of the pool that ends at the lateral end of the chamber. Therefore, based on the propagation of the waves generated from the chamber, opposite may include direct or geometric opposite as well as opposite.

[0070] As shown in the figure, the third region 46 can be shaped as a curve so that the part in this region is further away from the chamber than other parts in this region. For example, the bank region 46 ' can be curved so that the lateral side of the pool corresponding to the end of the chamber is adjacent and is positioned to be closer to the chamber than the region therebetween towards the middle part (for the mirror image pool) of the pool bank or the part of the relative lateral side (for the single-sided pool) of the pool. As shown in the figure, the bank region or the side of the pool relative to the chamber, therefore can include three curved regions, two outer regions on the opposite ends of the bank region, wherein the region is recessed towards the chamber with an inward concavity, and the inner curved region between the two outer regions in the middle of the bank region protrudes towards the chamber with an outward concavity.

[0071] As shown, the second region 44 may extend from the first region 42 to the third region 46. The region may be similarly sloped. The slope of the region may be linear, curvilinear, or curved. The region may include a gradual slope of the transition bottom surface from the first region 42 to the third region 46. The region may also be contoured to transition to any other region that may be included in the bottom contour. The second region 44 may thus provide a transition surface between two or more other floor bottom surfaces or regions.

[0072] The pool may include one or more other floor areas that define one or more other areas. For example, a first wave zone may be separated from a third wave zone. Spacing may create floor profiles to recreate a desired wave shape. Spacing may allow space between the various wave zones for the safety and enjoyment of the surfer. Figure 3 , 4 As shown in Figures 5 and 6, transition regions 48, 48' may be used. The transition regions 48, 48' may correspond to a substantially flat floor bottom 58. The transition regions may be located between the first region 42 and the third region 46 and the shore region. Figure 3 As shown, the first region 42' may be in contact with the third region 46' in the middle of the pool, while the transition portion 48' separates the first region 42' from the third region 46' and separates the outer lateral side of the pool near the second region 44'. Figure 4 As shown, a transition region 48 may separate the first region 42 from the third region 46 along the length of the pool such that the first region 42 does not contact the third region 46 .

[0073] In an exemplary embodiment, the gradient of the pool floor bottom 52 corresponding to the first area 42, 42' is greater than the gradient of the pool floor bottom 56 corresponding to the third area 46, 46' (α>β). In an exemplary embodiment, the gradient of the pool floor bottom of the second area 46, 46' is generally equal to either of the gradients of the first area and the second area, or between the gradients of the first area and the second area (α≥θ≥β). The pool floor bottom 52 may have a slope between 3 and 10 degrees. The pool floor bottom 56 may have a slope greater than 0 to 5 degrees. The pool floor bottom corresponding to the second area 46, 46' may have a slope of 2 to 10 degrees.

[0074] The configuration, shape, height, slope and other features of the pool floor bottom described herein are exemplary only. Other or additional features may be added and are within the scope of this specification. For example, additional inclined floors or one or more other horizontal floor areas may also be included to create additional wave zones or separate wave zones. Other elements may also be included, such as floor configurations, walls, dividers, high ground, shore features, etc., to further enhance the surfing experience or provide additional benefits to the pool wave generator described herein. These may include features for splitting, redirecting, reshaping or otherwise affecting the generated waves.

[0075] Figure 6 An exemplary wave generating chamber according to an embodiment of the invention is shown.

[0076] Conventional chamber configurations, where the chamber and pool share a common wall, or where the chamber and pool are in close proximity, create vortices through the area between the chamber and pool. The vortices may interfere with the shape and stability of the waves generated. USPN 10,526,806 discloses a blade located between or near the chamber and pool interface to control and direct the movement of water and reduce the formation of vortices. Since the blades must be supported and maintained internally, such a system incurs construction and maintenance costs. The exemplary embodiments described herein allow for the formation of a wave pool that can manage or reduce the formation of vortices without the use of blades or internal structures within or near the water flow path between the chamber and pool.

[0077] The chamber 62 and the configuration of the chamber 62 to the pool 64 can be used to generate waves with desired characteristics. The exemplary embodiment uses the chamber width (CW) and the width (wall width) WW between the pool and the chamber. In the exemplary embodiment, the width WW between the pool and the chamber is greater than 2 meters. However, the greater distance in this transition area between the chamber and the pool can affect and reduce the height of the waves generated. Therefore, traditionally, it is desirable to keep this area as short as possible. However, this distance can be used to reduce turbulence and generate a better wave profile. In the exemplary embodiment, the distance between the edge of the pool and the edge of the chamber is between 2 meters and 7 meters. CW may affect the final height of the waves generated. Similar to WW, this size is traditionally reduced because the additional width requires additional power for controlling and releasing the waves. For example, additional gas is required to generate the same pressure on the water surface. CW is preferably 1.3 to 5 meters.

[0078] In an exemplary embodiment, chamber 62 may be coupled to pool 64 via flow channel 66. The flow channel may be located at a lower depth than pool 64 so that water exits the chamber at or near the bottom of the pool and enters the pool. The flow channel may be shaped so that the direction of water exiting the flow channel may have a vertical component. The flow channel may include an inner wall 68B and an outer wall 68A. The inner wall 68B and the outer wall 68A may be curved to reduce turbulence imposed on the water as it passes from the chamber through the flow channel to the pool.

[0079] Exemplary embodiments described herein include chambers and control systems and methods. Exemplary embodiments of chambers and control systems and methods described herein may be used alone or in combination with any of the features described herein. For example, exemplary chambers and control systems may be used in configurations where chambers share a common wall with a pool. Exemplary embodiments may be used where water is stored and released from one or more chambers to control the flow of fluid into and out of a chamber.

[0080] like Figure 6 As seen in the figure, an exemplary embodiment may include a chamber 62 as described herein for storing and releasing water into a wave pool 64 to generate waves or other water effects in the pool. In an exemplary embodiment, the chamber 62 may have one or more valves to allow water and air to enter and exit the chamber. As shown, an exhaust valve 602 and an injection valve 604 are each used to exhaust air from the chamber and supply air to the chamber. In one embodiment, these valves may be the same valve. Therefore, the valve may be a one-way valve or a two-way valve. The chamber 62 may also be in fluid communication with a plenum 606 so as to supply additional air to the chamber as required. The plenum 606 may be coupled to a pump 608 to supply pressurized air to the chamber 62. In an exemplary embodiment, the chamber may also be configured to exhaust air under pressure, such as by a pump or other suction force, to provide a negative pressure in the chamber, or to quickly evacuate air from the chamber.

[0081] In an exemplary embodiment, one or more valves may be an opening or closing valve such that the valve transitions from fully open to fully closed.

[0082] In an exemplary embodiment, one or more valves may be actuated so that the valves may be controlled to be fully open, fully closed, or partially open. In an exemplary embodiment, one or more valves may be actuated mechanically, pneumatically, or otherwise to allow a full range of positions between open and closed. In an exemplary embodiment, one or more valves may be actuated mechanically, pneumatically, electrically, or otherwise to allow the valves to be gradually positioned within a range between fully open and fully closed. Exemplary embodiments of chambers and control systems described herein may use intermediate positioning of one or more valves to control the amount of water discharged in the chamber. In an exemplary embodiment, control systems and methods may be used to adjust wave frequencies to avoid or minimize conflicts between main waves and residual waves. In an exemplary embodiment, the control system may include one or more parameters that may be used to customize wave characteristics. Wave characteristics may include wave height, wave shape, wave profile, etc. Exemplary embodiments may use a combination of valve controls, including the allowable intermediate positioning of valves, as one or more parameters of wave generation, which may be used to generate more wave combinations. Exemplary embodiments of control systems described herein may reduce power consumption by approximately 10%. Exemplary embodiments of control systems described herein may reduce the total installed power of a facility.

[0083] Fig. 7A is from Figure 6 An exemplary progression of waves generated by a wave generating chamber. Fig. 7A The first step shown in is when the wave chamber and wave pool are ready to be launched to generate waves. In this initial state, the exhaust valve 702 is fully closed and the inlet valve 704 is fully open. The inlet valve 704 allows the pressurized air in the plenum chamber to enter the chamber and exert pressure on the water in the chamber to create a low water level below the water level in the wave pool. Fig. 7A In the second step shown, the chamber pressure is released. The exhaust valve 702 is fully opened and the intake valve 704 is fully closed. The air pressure in the chamber is thus released and the water in the chamber rises. As water moves from the wave pool into the chamber, the rising water in the chamber creates a void of water in the wave pool. This movement causes a localized decrease in the height of the water level in the pool near the chamber. Fig. 7A In the third step shown, the chamber pressure is increased again to release water from the chamber. As shown, the exhaust valve 702 is fully closed, while the intake valve 704 is fully opened. This allows the pressurized air to push the water and eject the water from the chamber through the flow channel into the wave pool. As shown, when the water is pushed from the chamber into the pool, waves are generated in the pool.

[0084] When the valve is used in this configuration, such that the valve is configured to transition between fully closed and fully open states, the air in the chamber can act as a spring. When the water in the chamber reaches a maximum or minimum height, the water level can rebound as the air is compressed and released, thereby creating an oscillating wave surface.

[0085] Figure 7B Shown in Fig. 7A An exemplary graph of the water level in the chamber at different times associated with an exemplary progression of a wave. Fig. 7A As seen in the comparison of the water states of the first and second conditions, the water level in the chamber starts out at a lower point / resting level 706. As the air is expelled, water enters the chamber and the water level increases to a maximum position 708. As the air is injected, water leaves the chamber and the water reaches a minimum. As best shown between the second and third conditions, where the chamber transitions between a vented state and a pressurized state, and water is drawn into the chamber and then released from the chamber, the water level recovers after reaching a minimum. However, the residual air in the chamber creates another oscillation in the chamber water level height, a residual wave, before the water level returns to the original lower point / resting water level position 710.

[0086] Figure 7C It is shown that the Figure 7B FIG. 7 is an exemplary wave pattern formed in a wave pool of a wave amplitude graph. The water level in the chamber produces the desired rideable waves or main waves 712 at the maximum and minimum values. However, the intermediate oscillations that may occur in the chamber may cause disturbing water effects between the desired waves. The disturbing water effects may be similar to fewer or smaller residual waves 714 between the desired wave effects.

[0087] In an exemplary embodiment, the valve system may be controlled to position one or more valves in an intermediate position between open and closed to dampen oscillations within the chamber caused by the movement of air and water within the chamber. For example, in an exemplary embodiment, between steps 2 and 3, rather than the exhaust valve transitioning from fully open to fully closed while the intake valve transitions from fully closed to fully open, the exhaust valve may be fully closed and thereafter may remain partially open or remain partially open through the transition between steps 2 and 3. Alternatively or additionally, the intake valve may be opened by varying amounts during the transition between steps 2 and 3 in order to control the flow of air into the chamber and dampen any spring action caused by the injected air within the chamber.

[0088] Figure 8An exemplary comparison of water amplitudes in a chamber on a time course graph for controlling a desired wave form in a wave pool using a chamber and control system according to embodiments described herein is shown. As shown, when water re-enters the chamber, the original water amplitude in the chamber oscillates between a minimum wave height and a maximum wave height. This can occur when one or more exhaust valves or inlet valves are set between fully open and fully closed states. The comparison graph shows an exemplary embodiment in which the inlet valve is partially opened so that the water level in the chamber does not result in the same sharp minimum, but rather includes a wave shape profile with a defined maximum and a truncated minimum, thereby minimizing the oscillation. As shown, the uncontrolled profile results in residual waves, while the controlled profile mitigates the generation of residual waves in the chamber. The adjustment parameters can be varied to achieve different water level height profiles and different performance characteristics.

[0089] Fig.9A and Fig. 9B An exemplary comparison of waves generated in a wave pool using the chambers and control systems and methods described herein is shown. Fig.9A Waves generated using the chamber and control system and methods described herein are shown, resulting in mitigation of residual waves. Fig. 9B Waves generated without the benefit of the systems and methods described herein are shown, wherein residual waves occur.

[0090] Fig. 9C and Fig.9D An exemplary comparison of water currents generated in a wave pool using the chambers and control systems and methods described herein is shown. Mitigating residual waves significantly reduces water currents in the pool, allowing for better wave quality, such as Fig. 9C (with controls) and results in a better and safer guest / surfing experience than when controls are not used, as shown Fig.9D shown.

[0091] Fig.11 An exemplary cross-sectional profile of a wave pool according to an embodiment of the present invention is shown. The exemplary wave pool 70 can include any combination of features as described herein. For example, the system can include a pool 64 having a pool floor. The pool floor can have one or more distinct regions, such as a first sloping region 52 adjacent to a chamber 62 that transitions to a third sloping region 56 via a generally flat transition region 54. As described herein, the chamber 62 can control the flow of water into and out of the chamber via one or more valves 22, 23, 24.

[0092] In an exemplary embodiment, the wave generating system may have a control system associated therewith for actuating one or more valves 22, 23, 24 to control the flow of water between the chamber and the pool. In an exemplary embodiment, the system includes an exhaust valve 23 for allowing air to flow out of the chamber and an injection valve 24 for allowing air to flow into the chamber.

[0093] In an exemplary embodiment, one or more valves including an exhaust valve or an injection valve may be coupled to an independent controller, such as a proportional integral derivative (PID) controller, a proportional integral (PI) controller, or a proportional derivative (PD) controller, to facilitate a control loop between one or more sensors of the system and the position of one or more valves. In an exemplary embodiment, a PID controller may follow the formula:

[0094]

[0095] u(t)=PID control variable

[0096] K p = Proportional gain

[0097] e(t) = error value

[0098] K i =Integral gain

[0099] de = change in error value

[0100] dt = change in time

[0101] The error may be the difference between the valve angle recorded by the sensor and the set point. In an exemplary embodiment, the feedback control loop for the exhaust valve position may be based on the difference between the pressure sensor and the set pressure point, and the feedback control loop for the injection valve position may be based on the difference between the water level in the chamber sensor and the set height point. Fig. 10A An exemplary feedback control loop is shown in which the valves are compared to determine valve position.

[0102] Fig. 10BAn exemplary control device for use with an injection valve is shown. In an exemplary embodiment, as the water returns to the chamber, the height of the water oscillates until it reaches a final height. The water level height oscillations in the chamber can be suppressed by reducing the opening of the inlet valve to reduce the pressure given to the chamber by the boost chamber. The water level can be measured by a level transmitter. Air pressure can be provided to the chamber through a valve, the position of which is controlled between fully closed and fully open (0 to 100% open). In an exemplary embodiment, a PID, PI or PD loop controller can be used to control the percentage of inlet valve opening to affect the water level to a set height point, and or optionally suppress wave harmonics. The set water level height point can be determined based on the wave shape or size generated. The selection of the set height point can be customized to affect the wave characteristics and more fully customize the waves generated.

[0103] The present invention includes a position control valve mounted on the chamber to control the amount of air delivered to the chamber from the plenum. A set of sensors connected to the chamber include, but are not limited to, a water level height sensor W for measuring the water level in the chamber, a pressure sensor P for measuring the pressure in the chamber. Other sensors may also be used, such as a temperature sensor for measuring the temperature in the chamber, a humidity sensor for measuring the humidity in the chamber, or a flow sensor mounted on the valve for measuring the flow rate through the valve. The plenum of one or more blowers pressurized by the blower is equipped with a temperature sensor to measure the temperature in the plenum. A power sensor is connected to the motor to measure the amount of power drawn by the blower motor. Alternatively, these sensors may be replaced by an ampere sensor mounted on the motor electrical conductor. For a motor controlled by a variable frequency drive (VFD), data calculated by the VFD may be used to replace the sensor. In addition, one or more temperature and humidity sensors are installed in the machine room to measure the air density in the machine room.

[0104] like Fig.11 As shown, the terminal end of the pool 64 towards the chamber can be separated by the chamber with a width WW. In an exemplary embodiment, the interval between the chamber and the pool can allow onlookers to observe. As shown, the space between the pool 64 and the chamber 62 includes a floor 78 on which observers can stand. The floor can be located around the water level of the pool 64, or at a higher position, so as to provide better observation for surfers in the area adjacent to the chamber or the rest of the pool. This area can include a stand 76 or other seating area or walkway to allow pedestrians or observers to pass by or observe the activities in the pool.

[0105] In an exemplary embodiment, in addition to or in place of a bystander's observation, the interval between the chamber and the pond can allow the storage of system components. For example, the zone between the pond 64 and the chamber 62 above the flow channel 66 can include the space for air plenum, pump equipment, blower, electronics, controller, equipment room or other system components. As shown in the figure, stands or seating area can include equipment room 86. Below the floor 78 or the space between the chamber and the pond can include other component parts, for example, the space for air plenum, electronics, controller or other equipment. As shown in the figure, the zone between the pond and the chamber includes the space for air plenum 84, and is positioned with an electrical room behind the chamber 86.

[0106] In an exemplary embodiment, the space between the pool 64 and the area 72 between the pool and the chamber 62 can be open and unobstructed. In this case, surfers, swimmers and lifeguards can enter the pool area from the floor 78 on the wave-generating side of the pool. In an exemplary embodiment, the wall 74 can extend beyond the height of the water to separate the space between the pool and the chamber from the pool itself. The wall 74 can be an extension of the side of the pool above the flow channel entrance. The wall 74 can be acrylic, plastic or other translucent or transparent material to allow observation of activities in the pool from a location outside the pool. The wall 74 can protect observers from getting wet or accidentally falling into the pool.

[0107] The exemplary embodiments described herein may include unique pool configurations for managing water flow to affect currents. Such exemplary configurations may be used to generate and maintain desired wave formations and allow wave shapes to be formed continuously or repeatedly in time along the length of the pool to minimize the elapsed time between wave formations. Thus, exemplary embodiments may include lagoons and troughs at the shallow end of the pool to direct water at the end of the wave. The lagoons or troughs may be used to absorb and dissipate currents within the pool.

[0108] As previously mentioned Figure 1A As described, an exemplary wave pool generator may include a pool area and one or more chambers for generating waves in the pool area. Waves 16 may propagate away from the chamber and toward the terminal of the pool. The terminal of the pool may be formed by the inclined bottom of the pool to simulate a beach area. When water is pushed through the pool area by releasing water from the chamber, the water may travel toward the terminal, travel through the inclined bottom and travel upward along the inclined bottom until the water stops, and eventually return to the pool area along the inclined bottom under the influence of gravity. However, the water returned to the pool may generate water currents that interfere with repeated wave generation. Therefore, exemplary embodiments may include additional water features to handle the movement of water.

[0109] Fig.12An exemplary embodiment of a wave pool is shown having a pool area 181 and one or more chambers 14 to generate waves 182 that move from the chambers to a shore area 185. The shore area can be created by a pool floor that tapers upward so that the water level of the pool area 181 meets the pool floor. An incoming wave 182 can push water upward onto a beach area 185 so that the location where the water meets the shore varies with the course of the wave. Thus, the shore area 185 can include a high water mark 184, which can be the highest level that the water can reach on the beach area 185 (or further away from the chamber) under a given wave course. The high water mark 184 can depend on factors of the wave generating device, including chamber release timing, pressure within the chamber, etc. The low water mark can be the location where the water along the beach area 185 naturally rests on the pool floor without waves, or the lowest location (closest to the chamber) where the water rests when a wave is generated.

[0110] Exemplary embodiments described herein may include a pool or trough where the pool floor reaches a peak in the beach area 185. The floor may then taper away or lower so that water may be captured in the second pool area 183. The second pool area 183 may be shallow to form a wading pool or lagoon, or may be deeper to form a trough or channel that directs water. The second pool area 183 may be used to capture water from the pool area 181 that passes through the beach area 185 and into the waves 182 of the second pool area 183. This water capture may reduce water returning to the pool area 181 and reduce the adverse effects of water currents generated from receding water.

[0111] Before transitioning to the second pool area 183, the highest point of the beach area may occur between the low water mark and the high water mark of the pool area 181, adjacent to the low water mark, at the low water mark, or a combination thereof along the beach area. For example, as shown, the highest point of the beach area on the lateral outer edge of the beach area 185 may be adjacent to the low water mark or within the low water mark, so that the pool area 181 and the second pool area 183 can be fluidly connected regardless of the generation of waves. The highest point of the beach area toward the central area of ​​the pool can be located outside or at the high water mark 184, so that the pool area 181 and the second pool area 183 are separated by the gap 186 of the raised floor, so that these pools are not fluidly connected through the gap (but can pass along other areas of the beach area). The highest point of the beach area can also be located between the low water mark and the high water mark, so that only when waves are generated and propagated through the beach area, the pool area 181 and the second pool area 183 will be fluidly connected along part of the beach area. In this case, water is captured as it is pushed up the shore and does not return directly to the pool area 181 from the exit location.

[0112] like Fig.12As shown, a combination of relative positions and spacings of the first pool area 181 and the second pool area 183 can be used. As shown, the first pool area and the second pool area can be in fluid communication along the length of the beach area from the outside to the edge toward the middle of the beach area during wave generation. The highest height of the pool floor between the first pool area 181 and the second pool area 183 can be approximately equal to the low water mark or between the low water mark and the high water mark. Towards the center of the pool area, the first pool area 181 can be separated from the second pool area 183 by a gap 186, so that the highest height of the pool floor between the first pool area 181 and the second pool area 183 along the gap is approximately equal to or above the high water mark.

[0113] like Fig.12 As shown, additional pool features may also be included. For example, lagoon 187 may be in fluid communication with second pool section 183 and first pool section 181. Lagoon 187 may be a shallow area to allow water to flow from second pool section 183 back to first pool section 181. As shown by the arrows, water may be controlled to flow through second pool section 183 so that water is captured from the first pool section when waves are generated. The water then flows along second pool section 183 to be recirculated back into the first pool section at a desired location. Fig.12 As shown, the desired location may be in the central area of ​​the beach area. Fig.14 In this case, water can be removed from the second pool area and reintroduced anywhere within the system. Fig.15 As shown, water may move along the second pool area to be reintroduced into other areas of the pool, such as lateral sides of the first pool area.

[0114] Exemplary embodiments of a wave generating device may include a beach area 188 adjacent to a second pool area or lagoon or other water feature where water may not be accessible and where onlookers may gather. Other viewing areas 189 may be provided along other sides of the wave generating device, such as on lateral sides of the pool area 181.

[0115] Exemplary embodiments may therefore include a pool configuration in which wave energy floods into a secondary pool area at a floor level corresponding to a desired water level (e.g., low water mark). The secondary pool area may be a deeper lagoon or trough. The secondary pool area may be configured to absorb and dissipate water flow from a primary pool or a pool for wave generation. In an exemplary embodiment, the primary pool and the secondary pool may be fluidly connected by a deep water channel, thereby maintaining the water levels of the primary pool and the secondary pool at equal heights without the need for a surge tank or pump.

[0116] Fig.13An optional pool configuration is shown having a first pool area 191 and a second pool area 193 to dissipate energy generated by waves 192. The main or first pool area 191 may include a low water line and a high water line as waves are generated and dissipated along a beach area 195. A desired water line 194 may be selected where the first pool area 191 and the second pool area 193 may be in fluid communication. The desired water line 194 may be located at the low water line, below the low water line, between the low and high water lines, or a combination thereof along the length of the beach area. The desired water line 194 may correspond to the highest height of the pool floor at a point between the first pool area and the second pool area. Similar to Fig.12 As illustrated, a gap 196 may be formed between a portion of the first pool area 191 and the second pool area 193 along the length of the beach area.

[0117] Fig.13 The embodiment may create a larger lagoon area at the beach area adjacent to the lateral sides of the main pool 191 at the opposite end of the beach area 195. The second pool area may thus include a slope extending into the main pool area 191. The second pool area 193 may then create a passage towards the center of the wave generating device to re-enter the main pool area at a location in the middle of the beach area.

[0118] In an exemplary embodiment, the wave generating device may include a deep water return channel 197. The deep water return channel 197 may fluidly couple the one or more secondary pools 193 to the main pool 191 away from the beach area 195 of the main pool. As shown, the deep water return channel 197 extends below the beach area 195 of the first pool 191 to fluidly couple to the floor of the first pool 191 adjacent to the chamber or closer to the chamber than the beach area.

[0119] Therefore, an exemplary embodiment may include a wave generating device having a first pool and one or more second pools. The first pool and one or more second pools may be configured so that the wave energy from the first pool washes over the desired water line or water level and enters the one or more second pools. As shown, two second pools may be used at opposite ends of the beach area of ​​the first pool. The second pool area may then be deepened and provide a water level and return channel to absorb and dissipate the water flow from the main pool. In an exemplary embodiment, the water may be returned to the first pool.

[0120] Fig.14An optional pool configuration is shown having a first pool area 111 and a second pool area 113 to dissipate the energy generated by waves 112. When waves are generated and dissipated along a beach area 115, the main or first pool area 111 may include a low water mark (L) and a high water mark (H). A desired water mark 114 may be selected, wherein the first pool area 111 and the second pool area 113 may be fluidly connected. The desired water mark 114 may be located at the low water mark, below the low water mark, or between the low water mark and the high water mark, or a combination thereof, along the length of the beach area. The desired water mark 114 may correspond to the highest height of the pool floor at a point between the first pool area and the second pool area. Similar to the description of FIG. 9, a gap 116 may be formed between a portion of the first pool area 111 and the second pool area 113 along the length of the beach area.

[0121] exist Fig.14 In an exemplary embodiment, water from one or more secondary pools may be removed from the wave generating device or main pool 111. In this case, the water may be directed to a water collection tank or other water feature, such as a lazy river or wading pool. In an exemplary embodiment, the other body of water may have a lower static water level to allow water to drain from the one or more secondary pools or channels formed thereby and enter the other body of water. In an exemplary embodiment, water from the other body of water may be pumped back into the main pool 111 or chamber 14. The flow rate and pump inlet location may vary depending on the pool configuration or other water body features.

[0122] In an exemplary embodiment, the second pool area 113 may be covered. The second pool area consists of a deeper channel that can capture water when it overflows from the main pool 111 during waves. The second pool area may be covered by a porous floor so that water can pass through the holes, but customers can walk on top of the second pool area. Therefore, all or part of the second pool area may not be used as part of the active area for water absorbing materials. Instead, the second pool area may be located below the beach area.

[0123] Exemplary embodiments provided herein include wave generating devices wherein wave energy can flow over static water level dividers and into one or more secondary pool sections. Thus, water can be discharged to a sump or other water structure at a lower static water level than the primary pool. Thereafter, water can be pumped from the pool or sections back into the pool to maintain the operating water level.

[0124] Fig.15An optional pool configuration is shown having a first pool area 1111 and a second pool area 1113 to dissipate the energy generated by waves 1112. When waves are generated and dissipated along a beach area 1115, the main or first pool area 1111 may include a low water mark (L) and a high water mark (H). A desired water mark 1114 may be selected, wherein the first pool area 1111 and the second pool area 1113 may be fluidly connected. The desired water mark 1114 may be located at the low water mark, below the low water mark, or between the low water mark and the high water mark, or a combination thereof along the length of the beach area. The desired water mark 1114 may correspond to the highest height of the pool floor at a point between the first pool area and the second pool area. In this exemplary embodiment, the ideal water mark 1114 is located at the low water mark or below the low water mark for a portion of the length of the beach area, and is approximately equal to the high water mark along another portion of the length of the beach area. In an exemplary embodiment, the desired water line may be located at the low water line or between the low water line and the high water line along the entire length of the beach area so that no gap is created between the first pool and the second pool, or a gap is only temporarily created between the first pool and the second pool during water generation.

[0125] like Fig.15 As shown by the arrows in FIG. 1 , the water in the one or more second pools may flow toward a lateral end of the beach area opposite the lateral side of the main pool 1111. The second pool 1113 may extend along the side of the pool 1111 and may be in fluid communication with the first pool 1111. In an exemplary embodiment, the bottom of the main pool 1111, either along the lower edge of the lateral side wall or through the floor of the pool 1111, may include a grid or holes to fluidly couple to the second pool 1113. Water may return to the first pool 1111 through the lower portion or bottom of the first pool 1111.

[0126] Exemplary embodiments described herein may include a wave generating device wherein wave energy may wash over a divider having a height at a desired water level and enter a secondary pool. The secondary pool may include a channel having a covering. The covering may allow water to pass through the covering, but may not allow a person or body part to pass through the covering. In an exemplary embodiment, the covering may conceal the channel within the beach area of ​​the first pool. In an exemplary embodiment, the flow of water in the channel may be weakened. The channel and the first pool may be fluidly connected by an opening in the bottom of the pool, thereby allowing the two bodies of water to maintain the same water level without pumping. Users and customers may also walk over the covering of the channel.

[0127] Provided herein are exemplary configurations of systems and methods for dissipating wave energy and controlling water flow in a main pool. Illustrative combinations are provided only by way of example. Any exemplary feature may be used in conjunction with any combination of other exemplary features. For example, any representative example may include a shallow open pool that may serve as a wading pool or lagoon as a second pool. Any representative example may include a channel with a cover so that the second pool does not produce a moving part. Any representative example may include a deep water return channel for connecting the second pool to the bottom of the first pool. Any representative example may include one or more pumps to help fluid flow and move water in a desired direction. Any representative example may have a first pool and a second pool that are fluidly connected during the entire wave generation period. Any representative example may have a desired water level line of any configuration that separates the top of the first pool from the top of the second pool to allow water from the first pool to overflow the desired water level line and enter the second pool. For example, any representative examples may position the desired water line below a low water line, approximately equal to the low water line, between the low water line and the high water line, or above the high water line, or any combination thereof, along the length between the first pool and the one or more second pools.

[0128] Exemplary embodiments described herein may include a pool wave generator having a pool area and a plurality of chambers on one side of the pool area for releasing water into the pool area to generate waves in the pool area. The pool area may include a first linear wall, and the plurality of chambers are configured to release water into the pool area along the entire length of the first linear wall. The pool area may also include two lateral side walls extending from a terminal end of the first linear wall at an oblique angle.

[0129] Exemplary embodiments may also include a pool wave generator having pool sections and any method of generating waves to propagate through the pool sections. The pool wave generator may also include one or more second pool sections. The first pool section and the second pool section may be separated by a divider having a desired water level. The height of the divider may vary along the length of the divider between the first pool section and the second pool section. The height of the divider may be at a low water level of the pool section during wave generation, at a still water level of the pool section when waves are not being generated, at or above a low water level of the pool section during wave generation, below a high water level of the pool section during wave generation, and combinations thereof.

[0130] The second pool may be located between the pool area and the chamber. The second pool may be configured to form a channel for water to travel laterally across the length of the pool area and minimize the amount of water returning to the pool at the exit location of the water leaving the pool area after a wave. The second pool may be positioned to receive water leaving the pool area during a wave to minimize direct return of water back into the pool area.

[0131] The second pool area may be in fluid communication with the first pool area via a deep water channel located below the floor of the first pool area.

[0132] The water received in the second pool can be transferred to another water structure. For example, the other water structure can be a separate water activity area, such as a wading pool, a pool, a lazy river or a combination thereof.

[0133] The second pool may include a channel. The channel may be configured to extend around the lateral sides of the pool area. The channel may be configured to reintroduce water from the channel into the pool area at the bottom of the pool area.

[0134] The second pool may be covered, wherein the cover includes perforations to allow fluid to flow therethrough but to prevent body parts from passing through the cover.

[0135] Fig.16 Shows something like Figure 4 1201. As shown, the pool floor may include a return channel 1201 located in the center of the pool. The return channel may be a floor profile to facilitate the movement of water flow from the first pool or the second pool as described herein. For example, the exemplary floor may include a continuous, gradually narrowing area to allow the return water to smoothly transition back into the pool. The return channel 1201 may promote a phenomenon similar to an eddy current. All or a portion of the return channel 1201 may be at one or more locations or lengths, at a lower height relative to the pool floor on the opposite lateral sides of the return channel.

[0136] Fig.17 1702 is a valve group including one or more valves 1702 equipped with a position control actuator 1701 that allows the valve to open to 0 degrees (fully open) or 90 degrees (fully closed) and any position in between, where the position of the valve is provided to the actuator controller by a main controller signal. The reaction of the actuator in response to the signal can be tuned by the actuator controller. Fig.17 As shown, valve 1702 is fully open.

[0137] Fig.18 A typical throttle valve characteristic is shown, showing that the pressure drop across the valve or throttle increases as the degree of opening increases. By controlling the degree of opening of the valve, one can control the pressure drop across the valve and the amount of air transmitted through the valve.

[0138] Fig.19 is a block diagram describing the calculation of the valve opening required to meet the target water level. A controller method is shown for calculating the valve opening based on the water level target, the current water level in the chamber, the pressure in the chamber, the temperature in the plenum chamber, the power consumed by the blower motor, and the temperature and humidity in the mechanical chamber, and using known laws of fluid dynamics to measure. set is the target height received from the user interface. Z w is the actual water level measured by the sensor. The error is given by e in Indicates that in It's Z set and Z w This error calculates the angle needed to reach the target, which then sends a signal to the actuator to open the valve to the appropriate degree. This process repeats as the system continually measures, recalculates, and adjusts as needed.

[0139] Figures 20A-20D Shown in Fig.19 The position of the valves and water levels of the systems and methods at each of the points 1, 2 and 3 shown in FIG. Although certain sensors are shown and described in these figures, additional or alternative sensors may be used as described above.

[0140] Fig.21 The evolution of the water level in different chambers is shown. As described above, the pool wave generator and the pool can be configured to generate two waves in the same pool. For example, one wave moves generally toward the left side of the pool, while the second wave moves generally toward the right side of the pool. The present invention allows the ability to have different water level height targets in the chambers, thereby allowing the chambers to generate waves of different sizes simultaneously. For example, a more skilled surfer may require a larger wave, while a novice surfer in the same pool may require a smaller wave. Fig.21 This depicts a situation where the first wave produces a larger amplitude, while the second wave is relatively smaller. This allows the pool to accommodate groups of different competitive levels simultaneously and reduces peak power consumption.

[0141] Fig. 22 A method of generating waves with a maximum amplitude that is greater than the normally possible amplitude for a given equipment setup is shown. In this method, the height of the water in the chamber is controlled to rise, allowing the system to generate a first, small amplitude wave (excitation) to get the water moving, thereby generating larger waves later. Fig. 22As shown, the dashed line represents the maximum wave amplitude for a given system. Compared to an uncontrolled method, the maximum wave height can be increased by 25%, resulting in waves exceeding the normal maximum amplitude. Also as described above, when the valve is used in this configuration, such that the valve is configured to transition between fully closed and fully open states, the air in the chamber can act as a spring. When the water in the chamber reaches a maximum or minimum height, the water level can rebound as the air is compressed and released, thereby generating an oscillating wave surface.
