[0001] Divisional application

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

[0005] Water park facilities bring enjoyment to diverse groups of people from different geographical locations across generations. They allow people from different regions to experience simulated experiences from other places. For example, a wave pool can simulate the experience of a beach.

[0006] Different water attractions can be used to simulate natural environments, allowing users to experience sports and activities derived from these other environments. For example, a sheetboard surfing device simulates the experience of surfing or skating, allowing surfers to use their bodies or sheetboards to surf on a sheet of water formed by the contours of the underlying surf surface. Because the sheet-like water flow does not allow for wave breaking or the use of a real surfboard, sheetboard surfing does not provide a realistic surfing experience.

[0007] This application provides a deep-water wave surfing system that attempts to create a more accurate simulation of the surfing experience in a natural environment. US Patent Nos. 8,434,966; 9,103,133; 9,279,263; 10,145,135; 10,280,640; and 10,526,806 disclose deep-water wave surfing simulators, the entire contents of each of which are incorporated herein by reference.

[0008] Deepwater wave surfing devices present unique challenges in managing the large amounts of water used in the equipment. For example, currents and eddies can form, disrupting wave formation. Managing the air and water entering and leaving the chambers is also problematic. Air within the chambers can act like springs, and the momentum of water leaving and returning to the chambers can generate undesirable forces, oscillations, and other motions on the water. These forces, in turn, can create undesirable wave effects, turbulence, and other adverse characteristics within the resulting waves. Summary of the Invention

[0009] This invention discloses a pool wave generator having a pool area and multiple chambers for generating waves in the pool area. The multiple chambers can be used to store or release water into the pool to generate desired waves.

[0010] The exemplary embodiments described herein may include unique pool and chamber configurations for managing fluid flow, including water and air within the chambers, to influence desired wave morphology and control or minimize undesired wave effects. Exemplary embodiments of the systems and methods described herein can be used to control various characteristics of waves, such as water level height within the chambers, which can be used to suppress residual waves after wave generation in the pool. Such exemplary configurations can be used to generate and maintain desired wave formation and allow for repetitive wave formation, either continuously repeated along the length of the pool or timely repetition of desired time interfaces, such as repetition over the time length between waves. Exemplary embodiments can also be used to control and define customized waves, which may have controllable or programmable individual characteristics.

[0011] Although the description herein pertains to a deep-water wave pool with specific features, including the pool shape, the chamber for releasing water, and the channel for controlling the return of water to the pool, these embodiments are merely exemplary. Exemplary embodiments of the chambers and control systems and methods for generating waves can be used in various aquatic environments. For example, the embodiments described herein can be used to generate waves for surfing, or simply for wave pools. Exemplary embodiments can be used in other water surfing devices in which water is contained and released in a controlled manner. Attached Figure Description

[0033] The following detailed description illustrates the principles of the invention by way of example rather than limitation. This specification will clearly enable those skilled in the art to make and use the invention, and describes various embodiments, modifications, variations, substitutions, and uses of the invention, including those currently considered to be the best mode for carrying out the invention. It should be understood that the accompanying drawings are schematic and illustrative representations of exemplary embodiments of the invention and are not intended to limit the invention, nor are they necessarily drawn to scale.

[0034] The 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 zones to define or generate waves of different profiles, or for use by individuals with different levels of experience. The pool may also be configured as a floor structure or include additional water features, such as lagoons and channels for controlling water flow to dissipate wave energy and control water flow.

[0035] While embodiments of the invention are described and illustrated herein with reference to a pool wave generator having unique and novel features, it should be understood that embodiments of the invention do not require or need to include every feature. This disclosure does not require any particular component, construction, or feature, and any combination of features may be incorporated or combined and remain within the full description of the invention. For example, including an elongated chamber between the chamber and the pool to reduce eddies can be used in any conventional feature of a pool wave generator. Similarly, including an observer region or bottom profile to generate different wave zones can be used similarly 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. The 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 the chambers 14 and toward the end 18 of the pool.

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

[0038] Figure 1A An exemplary pool wave generator including two sides is shown, wherein waves can propagate from the chamber to the opposite end of the pool. Figure 1A The view in the image is depicted as a view of the pool from above. The pool wave generator of this embodiment can be used to generate different zones, which may have similar or different wave profiles for use by different surfers. Different zones can be used to create waves for surfers or participants of varying experience levels. An exemplary embodiment includes a pool wave generator in which waves propagate in a single direction, for example... Figure 1B As shown in the image.

[0039] As indicated by the arrows adjacent to chamber 14, chamber 14 can sequentially release water into pool area 12. The chambers can be linearly aligned along one side of the pool. The chambers can also include different orientations, configurations, and orientations. Releasing water from the chambers can be used to control wave properties such as wave height, direction, shape, and time intervals between waves. As shown, the chambers facing the middle of a plurality of chambers are released together, and then the chambers can be released sequentially outwards, thus moving outwards towards opposite ends of the plurality of chambers. The chambers can also be configured to release water in different directions or in different sequences, such as from one end to the other or from opposite ends towards the middle of the plurality of chambers.

[0040] Figure 1A An exemplary embodiment is shown, wherein chambers are arranged linearly 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 side of the pool wall 19 may extend at a non-zero angle, 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 components extending outward along a continuous extension in the linear direction of the chambers, thus forming a non-zero, non-perpendicular angle with the linear extension of the pool edge including the chambers. Angling the pool walls reduces the amount of water required to fill the pool and reduces the pool area that may generate less desirable wave effects.

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

[0042] In an exemplary embodiment, the wave generation system may include a control system. The control system may include sensors within the chamber. The sensors may include one or more sensors. In an exemplary embodiment, the sensors 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 within the chamber. In another embodiment, a pressure sensor may be used to determine or simulate the water level within the chamber. Other control sensors may be combined, for example, in the pressurization chamber, at the exhaust port, at the intake valve or intake valve actuator, at the pressure blower, at the blower motor, or at a control panel controlling the blower motor. Any combination of sensors may be configured as input to the control system to aid in the operation or control of the chamber. In an exemplary embodiment, the control system is configured to receive input from one or more sensors and to control one or more valves in response to the received sensor input.

[0043] In an exemplary embodiment, the control system may include actuators for setting the position of one or both of valves 23, 24 to transition the valve from fully open to fully closed, or to 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 exhaust valve are equipped with position controllers such that one or more valves can be opened to any position from fully open to fully closed, and to any position between fully open and fully closed.

[0044] In an exemplary embodiment, one or more sensors within the chamber may be used to measure the water level height within the chamber. In an exemplary embodiment, the sensors are positioned at the top of the chamber. In an exemplary embodiment, the sensors are configured to provide input to a control system, enabling the control system to determine the water level height within the chamber. The control system may be configured to control an vent valve or an inlet valve to control the desired water level height within 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 may be in fluid communication with the chamber.

[0046] The exemplary embodiments described herein may include a control system capable of setting the position of one or more valves to be 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] The exemplary embodiments described herein may include a control system capable of positioning one or more valves from any position fully open to fully closed, and any intermediate position between fully open and fully closed. An exemplary embodiment includes positioning one or more valves in an intermediate position between fully open and fully closed. The control system may be configured to control the corresponding wave height via a height setpoint rather than a VFD frequency.

[0048] like Figure 2A As shown, the system may have been released, resulting in no water in chamber 20 or a low water level 28 in the chamber (e.g., Figure 2C (As shown). The second valve 23 can be opened to vent air from the chamber. The chamber 20 can be configured to evacuate air from the chamber 20, thereby negatively pressurizing the chamber. The second valve 23 can also be opened to neutralize the pressure in the chamber 20 and allow air to escape from the chamber when it is filled with water. The first valve 22 is opened, and water rushes into the chamber, raising the water level in the chamber.

[0049] like Figure 2B As shown, the first valve 22 is closed to maintain the water level 28 in the chamber above the water level 26 in the pool. 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, pressurized air in the chamber pushes the water level 28 in the chamber, which in turn causes water to gush out of the chamber, generating waves 26' that propagate across the pool. The first valve 22 can be closed, and the air in the chamber is expelled, for example, through the second valve 23.

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

[0052] The first valve 22 can also remain open to allow water to return to the chamber, and as per [the relevant regulations] Figure 2B Close it as discussed.

[0053] In an exemplary embodiment, the control system may be configured to control a second valve 24 for supplying air into the chamber and a third valve 23 for removing air from the chamber. The system may also include one or more sensors used as inputs to the control system for determining the water level height within the chamber or the air pressure within 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 such that the second valve 23 and the third valve 24 are positioned to control the water level height within the chamber and / or maintain a desired pressure within the chamber.

[0054] Exemplary embodiments may include a user interface in which the control system can be programmed. The user interface may be configured to display information to a user and to receive input from the user. The user interface may be used to provide settings for the control system, such as when determining a desired relationship between valve position and sensor inputs. In an exemplary embodiment, the user interface is configured to receive desired water level profile information, such as a water level profile in a chamber, describing desired wave characteristics from the user, wherein the system is subsequently configured to determine control parameters to achieve the desired wave characteristics. Therefore, 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, etc. The system may be used to generate unique and fully customized waves because each chamber can be fully actuated to produce combined effects with water, thereby constructing virtually any wave.

[0055] In an exemplary embodiment, the system is configured to circulate the process of releasing water from the chamber and allowing the water to flow 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 could affect wave generation.

[0056] In the exemplary embodiments provided, three valves are shown: a first valve 22 for water control, a second valve 23 for gas control, and a third valve 24 for gas control. Any combination of valves can be used, and such combinations are within the scope of this 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 retain water in the chamber. The order and circulation of the valves described herein are merely exemplary. Any number of different methods can be used to release waves using valves, gates, or other methods. Valves can be opened and closed in different ways. For example, the system can use a purging system to remove gas from the chamber before water flows back, thereby raising the water level returning to the chamber. For example, the system can discharge water into the pool without using a pressurized gas system. For example, a one-way valve can be used, such that the valve does not require individual actuation to open and close. The valves in each chamber can be controlled individually or sequentially as part of the 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 is required to suppress residual waves generated by water oscillations within the chamber. Exemplary embodiments of the control system described herein can be used to control the generation (or reduction) of water flow within the pool. The exemplary embodiments described herein can lead to more efficient operation of the wave pool and also extend the lifespan of the equipment.

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

[0059] In an exemplary embodiment, multiple wave zones 36, 37, and 38 can be created. The creation of multiple wave zones can be achieved by a single wave generation cycle within a chamber. For example, the chamber can be released sequentially to form a first wave. This first wave can vary in profile, height, direction, etc. The wave can also be altered or reshaped 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 can have a mirrored configuration, resulting in six wave zones throughout the pool. However, three of these wave zones are independent of the other three, because the wave or part of the wave generating the first three wave zones is different from the wave or part of the wave generating the second three wave zones. Any combination of wave zones can be generated, and the combination of the two sides of the three zones for a total of six zones is merely illustrative. In an exemplary embodiment, the wave pool can have one, two, three, or more wave zones. The pool can have a mirrored configuration, for example... Figure 1AThe structure within the pool can double the wave zone, or the pool can be configured as follows: Figure 1B One side of the pool. The opposite sides of the pool can also be constructed differently, allowing different wave zones to be created across the entire pool.

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

[0061] As shown in the diagram, after the wave leaves the chamber, the second wave zone 37 can be located in an area extending along the side wall or edge of the pool. After the wave propagates out of the chamber, it dissipates energy and decreases in height. Therefore, this zone is designed for intermediate and longboard surfers.

[0062] As shown in the figure, the third wave zone 38 can be located adjacent to the side of the pool away from the chamber. This edge can correspond to the pool's edge area 46'. This area can have a shallow depth and can have a sloping floor bottom. The first wave zone 36 is available for surfers learning to wave. This area can also be used with surfboards, foam boards, kayaks, or surfboards. This area can also be used for body surfing or wave jumping.

[0063] The bottom of the pool may have areas corresponding to or influencing wave zones. For example, a first area 42' of the pool bottom may substantially correspond to a first wave zone 36, a second area 44' of the pool bottom may substantially correspond to a second wave zone 37, and a third area 46' of the pool bottom may substantially correspond to a third wave zone 38. A fourth area 48' and other areas can be used to generate and separate different wave zones and to modify waves as they propagate from the chamber. The different areas of the pool floor will be referenced... Figure 4 To have a more thorough discussion.

[0064] Different areas of the floor can be used to influence the wave profile. For example, the depth of the floor can affect the wave size, while the slope of the floor can affect the wave shape. Therefore, the first area 42' adjacent to the chamber can generate wave zone 36 for the most experienced surfers. This area can be approximately 2-6 meters deep. Thus, this area can have a floor bottom with a large slope or a lateral slope towards the pool shore or edge, or it can have the maximum 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 wave zone 38 for the least experienced surfers. Thus, this area can have a floor bottom with the smallest slope or a slope towards the edge, or it can have the shallowest depth. A gentler slope can make the waves more gentle.

[0065] In an exemplary embodiment, the pool edge away from the chambers may also be contoured to influence wave characteristics. For example, in the region of the third wave zone, or in the beginner zone, the edge may rise towards the center of the pool, on the side of the pool opposite to the middle chamber in the chamber sequence. This elevation may form a bank or dry indentation on the side of the pool. As waves propagate from the chambers towards the bank across the pool, the waves may extend around the elevation into the pool area. Other or additional elevations may be provided along short sections to create additional wave zones. In an exemplary embodiment, the elevation may be used to separate or redirect waves.

[0066] As shown in the figure, chambers can sequentially release water into a pool, thereby generating waves. If the chambers first open in the middle of the chamber sequence and then sequentially open towards each end in opposite directions, left and right waves will propagate from the chambers and break almost simultaneously. The chamber sequence can also be delayed or offset so that the left and right breaking waves can stagger. An expert wave zone can be defined as the area adjacent to or near the chambers. Waves within the expert wave zone can break along the wave-generating walls. Since the continuous release of water from the chambers can be used to maintain wave formation, the waves can maintain an approximately constant height. In an exemplary embodiment, the wave height in the expert wave zone can be approximately 1.5 to 3.5 meters. After the waves leave the area near the chambers, the waves dissipate energy, and the wave height decreases. Waves extending away from the chambers along the side edges of the pool can form a medium wave zone, whose wave height decreases from the expert wave zone. In an exemplary embodiment, the wave height in the medium wave zone can be approximately 1-2 meters. The wave height can continue to decrease as the waves leave the chambers. The waves can then break along the opposite side of the pool in the shallow water area to create a larger wave zone. In an exemplary embodiment, the wave height in the novice wave zone can be approximately 0-1.5 meters.

[0067] Figure 4 It shows the relationship with Figure 3 An exemplary bottom profile corresponding to the different wave zones of the pool wave system 40 described herein. Figure 5A yes Figure 4 An exemplary bottom cross-section view with reference line 50. Figure 5B It shows along Figure 5A The cross-sectional perspective view of reference line 50 in the figure shows the pool floor. As shown, the bottom section may include at least three areas.

[0068] In an exemplary embodiment, the first region 42 may correspond to a region adjacent to the chamber 14. For example... Figure 5BAs shown, the pool floor 52 of this region may include a gradual upward slope, such that the pool adjacent to the chamber is deeper than the pool on the opposite side of this region 42. This slope may move at an angle α from deeper to shallower across a region away from the chamber. The first region 42 may be generally rectangular, and as shown... Figure 4 As shown, it extends directly in front of the chamber. The first region 42 may also flare outwards at its ends, such that it traverses the front of the chamber and extends outwards beyond the ends of the chamber when the region is inclined away from it. Figure 3 As shown. Other shapes for this area are also conceivable.

[0069] In an exemplary embodiment, the third region 46 may correspond to a region on the end of the pool opposite to chamber 14. The third region 46 may be on one side of the pool, corresponding to the end of the wave's propagation opposite the origin of the wave. The pool floor 56 of this region may have a gentler, gradual slope than the region adjacent to the chamber. The pool floor 56 may include an upward gradual slope such that the pool is deeper toward the first region 42 than the region on its opposite side. The end of this region may have zero depth, allowing water to wash laterally to the surface. This region may simulate a beach area. The slope may traverse the region at an angle β from deeper to shallower in a direction away from the chamber. This region may correspond to a band or width at the end of a wave on the side of the pool opposite to the chamber. Because the chamber can generate waves that propagate out of the chamber at an 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 terminates at the lateral end of the chamber. Therefore, based on the propagation of the waves generated from the chamber, the opposite may include direct or geometrically opposite and reverse.

[0070] As shown, the third region 46 can be shaped as a curve such that a portion of this region is further away from the chamber than other portions of the region. For example, the bank region 46' can be curved such that a portion of the pool's lateral side adjacent to and toward the middle of the pool bank (for a mirrored pool) or the opposite lateral side of the pool (for a single-sided pool) at the end of the chamber is positioned closer to the chamber than the regions in between. As shown, the bank region or side of the pool opposite the chamber can therefore include three curved regions: two outer regions at the opposite ends of the bank region, where the outer regions are concave inward toward the chamber, and an inner curved region between the two outer regions in the middle of the bank region convex outward toward the chamber.

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

[0072] The pool may include one or more additional floor zones defining one or more other areas. For example, a first wave zone may be separated from a third wave zone. The intervals may be created by establishing floor profiles to recreate the desired wave shape. These intervals may allow space between the various wave zones, providing safety and enjoyment for surfers. Figure 3 , 4 As shown in Figure 5, transition regions 48 and 48' can be used. Transition regions 48 and 48' may correspond to the generally flat floor bottom 58. The transition regions may be located between the first region 42 and the third region 46 and the shoreline region. Figure 3 As shown, the first region 42' may contact 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 portion of the pool near the second region 44'. In an exemplary embodiment, as... Figure 4 As shown, the transition region 48 can separate the first region 42 and the third region 46 along the length of the pool, so 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 regions 42, 42' is greater than the gradient of the pool floor bottom 56 corresponding to the third regions 46, 46' (α > β). In an exemplary embodiment, the gradient of the pool floor bottom of the second regions 46, 46' is typically equal to either the gradient of the first region or the gradient of the second region, or between the gradients of the first region and the second region (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 regions 46, 46' may have a slope between 2 and 10 degrees.

[0074] The construction, shape, height, slope, and other features of the pool floor bottom described herein are merely exemplary. Other or additional features may be added, and these features are within the scope of this specification. For example, additional sloping floor sections or one or more other horizontal floor sections may be included to create additional or separate wave zones. Other elements, such as floor construction, walls, dividers, elevations, shoreline features, etc., may also be included to further enhance the surfing experience or provide additional benefits to the pool wave generator described herein. These may include features for breaking, redirecting, reshaping, or otherwise influencing the generated waves.

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

[0076] Traditional chamber constructions, where the chamber and pool share a common wall or are very close together, generate eddies through the area between the chamber and pool. These eddies can interfere with the shape and stability of the resulting waves. USPN10,526,806 discloses a blade located between or near the interface between the chamber and pool to control and guide water movement and reduce eddy formation. Such a system incurs construction and maintenance costs because the blade must be internally supported and maintained. The exemplary embodiments described herein allow for the formation of wave pools that manage or reduce eddy formation without using blades or internal structures within or near the water flow path between the chamber and pool.

[0077] The configuration of chamber 62 and the connection between chamber 62 and pool 64 can be used to generate waves with desired characteristics. Exemplary embodiments use a chamber width (CW) and a width (wall width) WW between the pool and the chamber. In an exemplary embodiment, the width WW between the pool and the chamber is greater than 2 meters. However, a greater distance in this transition region between the chamber and the pool can influence and reduce the height of the generated waves. Therefore, it is conventionally desirable to keep this region as short as possible. However, this distance can be used to reduce turbulence and generate a better wave profile. In an exemplary embodiment, the distance between the edge of the pool and the edge of the chamber is between 2 meters and 7 meters. CW can affect the final height of the generated waves. Similar to WW, this dimension is conventionally reduced because the additional width requires additional power for controlling and releasing the waves. For example, additional gas is needed 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 connected to pool 64 via flow channel 66. This flow channel may be located at a depth lower than pool 64, allowing water to exit the chamber and enter the pool at or near the bottom of the pool. The flow channel may be shaped such that the direction of water exiting the flow channel can have a vertical component. The flow channel may include an inner wall 68B and an outer wall 68A. The inner wall 68B and outer wall 68A may be curved to reduce turbulence applied to the water as it flows 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 the 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 a construction where a chamber shares a common wall with a pool. Exemplary embodiments may be used where water is stored and released from one or more chambers to control fluid inflow and outflow from the chambers.

[0080] like Figure 6 As seen herein, exemplary embodiments 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 within the pool. In exemplary embodiments, 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 respectively used to exhaust air from the chamber and supply air into the chamber. In one embodiment, these valves may be the same valve. Thus, the valves may be one-way or two-way valves. Chamber 62 may also be in fluid communication with a pressurization chamber 606 to supply additional air to the chamber as needed. The pressurization chamber 606 may be coupled to a pump 608 to supply pressurized air to the chamber 62. In exemplary embodiments, the chamber may also be configured to exhaust under pressure, for example by a pump or other suction, to provide negative pressure within the chamber or to rapidly evacuate air from the chamber.

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

[0082] In exemplary embodiments, one or more valves may be actuated such that the valves can be controlled to be fully open, fully closed, or partially open. In exemplary embodiments, one or more valves may be mechanically, pneumatically, or otherwise actuated to allow the full range of positions between open and closed. In exemplary embodiments, one or more valves may be mechanically, pneumatically, electrically, or otherwise actuated to allow the valves to be progressively positioned within a range between fully open and fully closed. Exemplary embodiments of the chamber and control system described herein may use intermediate positioning of one or more valves to control the amount of water drained from the chamber. In exemplary embodiments, the control system and method may be used to adjust wave frequencies to avoid or minimize conflicts between the primary wave and residual waves. In exemplary embodiments, the control system may include one or more parameters that can be used to customize wave characteristics. Wave characteristics may include wave height, wave shape, wave profile, etc. Exemplary embodiments may use combinations of valve controls, including permissible intermediate positioning of the valves, as one or more parameters of wave generation, to generate more wave combinations. Exemplary embodiments of the control system described herein may reduce power consumption by approximately 10%. Exemplary embodiments of the control system described herein may reduce the total installed power of the facility.

[0083] Figure 7A From Figure 6 An exemplary process of wave generation chambers generating waves. Figure 7A The first step shown 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 intake valve 704 is fully open. The intake valve 704 allows pressurized air in the pressurization chamber to enter the chamber and apply pressure to the water in the chamber to create a low water level below the water level in the wave pool. Figure 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 voids in the wave pool. This movement causes a localized decrease in the water level in the pool near the chamber. Figure 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 open. This allows pressurized air to push the water and spray it from the chamber through the flow channel into the wave pool. As shown, waves are generated in the pool as the water is pushed from the chamber into the water pool.

[0084] When the valve is used in this configuration, it is designed to transition between a fully closed and fully open state, with the air inside the chamber acting as a spring. When the water in the chamber reaches its maximum or minimum height, the water level can rebound as the air is compressed and released, thus creating an oscillating wave surface.

[0085] Figure 7B It shows that in relation to Figure 7A An exemplary graph showing the water level in the chamber at different times associated with an exemplary wave process. (As shown in...) Figure 7A As can be seen from the water state comparison, the water level in the chamber initially begins at a lower point / static level 706. When air is expelled, water enters the chamber and the water level increases to a maximum position 708. When air is injected, water leaves the chamber, and the water level reaches a minimum. As best illustrated between the second and third states, where the chamber transitions between a ventilated state and a pressurized state, and water is drawn into and then released from the chamber, the water level recovers after reaching a minimum. However, before the water level returns to its original lower point / static water level position 710, the residual air in the chamber creates another oscillation in the chamber water level height, a residual wave.

[0086] Figure 7C It shows the corresponding Figure 7B The wave amplitude curve illustrates an exemplary wave pattern formed in a wave pool. The water level height in the chamber generates the desired rideable wave or main wave 712 at its maximum and minimum values. However, intermediate oscillations that may occur within the chamber can cause interfering water effects between the desired waves. This interfering water effect can resemble fewer or smaller residual waves 714 between the desired wave effects.

[0087] In an exemplary embodiment, the valve system can be controlled to position one or more valves in an intermediate position between open and closed to suppress oscillations within the chamber caused by the movement of air and water within the chamber. For example, in an exemplary embodiment, instead of transitioning from fully open to fully closed between steps 2 and 3, the exhaust valve transitions from fully closed to fully open simultaneously with the intake valve. The exhaust valve can be fully closed and subsequently held partially open or held partially open during the transition between steps 2 and 3. Alternatively or additionally, the intake valve can be opened by a varying amount during the transition between steps 2 and 3 to control airflow into the chamber and suppress any spring action caused by the injected air within the chamber.

[0088] Figure 8An exemplary comparison of water amplitude within a wave pool using a chamber and control system according to embodiments described herein to control a desired wave pattern is shown on a time-varying graph. As shown, when water re-enters the chamber, the initial water amplitude within the chamber oscillates between a minimum wave height and a maximum wave height. This can occur when one or more vent valves or inlet valves are positioned between fully open and fully closed states. The comparison graph illustrates an exemplary embodiment where the inlet valve is partially open, so that the water level within the chamber does not result in the same abrupt minimum, but rather comprises a wave shape profile with a defined maximum and a truncated minimum, thereby minimizing oscillation. As shown, an uncontrolled profile results in residual waves, while a controlled profile mitigates the generation of residual waves in the chamber. Adjustment parameters can be varied to achieve different water level profiles and different performance characteristics.

[0089] Figure 9A and Figure 9B An exemplary comparison of waves generated in a wave pool using the chambers and control systems and methods described herein is shown. Figure 9A The wave generated using the chamber and control system and method described herein is shown, resulting in the mitigation of residual waves. Figure 9B The diagram shows waves generated without benefiting from the systems and methods described herein, where residual waves occur.

[0090] Figure 9C and Figure 9D An exemplary comparison of water flow generated within a wave pool using the chamber, control system, and method described herein is shown. Mitigating residual waves significantly reduces water flow within the pool, thereby allowing for better wave quality, such as… Figure 9C (With controls) as shown, and resulting in a better and safer guest / surfing experience than when controls are not used, such as Figure 9D As shown.

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

[0092] In an exemplary embodiment, the wave generating system may have an associated control system 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 exit the chamber and an injection valve 24 for allowing air to enter the chamber.

[0093] In an exemplary embodiment, one or more valves, including an exhaust valve or an injection valve, may be coupled to a separate 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 positions of one or more valves. In an exemplary embodiment, the 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 over time

[0101] The error can 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 vent valve position can be based on the difference between the pressure sensor and the set pressure point, and the feedback control loop for the injection valve position can be based on the difference between the water level height in the chamber sensor and the set height point. Figure 10A An exemplary feedback control loop is shown, in which these valves are compared to determine the valve position.

[0102] Figure 10BAn exemplary control device for use with an injection valve is shown. In an exemplary embodiment, the water level oscillates as water returns to the chamber until it reaches a final height. The pressure supplied to the chamber by the pressurization chamber can be reduced by decreasing the opening degree of the air intake valve, thereby suppressing the oscillation of the water level height within the chamber. The water level can be measured by a level transmitter. Air pressure can be supplied to the chamber via a valve whose position 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 the air intake valve opening to influence the water level at a set height point and, optionally, suppress wave harmonics. The set water level height point can be determined based on the shape or size of the generated waves. The selection of the set height point can be customized to influence wave characteristics and more fully customize the generated waves.

[0103] This invention includes a position control valve mounted on a chamber to control the amount of air delivered from the pressurization chamber to the chamber. A set of sensors connected to the chamber includes, but is not limited to, a water level sensor W for measuring the water level in the chamber and 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 to measure the velocity of the flow through the valve. The pressurization chamber of one or more blowers pressurized by a blower is equipped with a temperature sensor to measure the temperature in the pressurization chamber. 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 ampere sensors mounted on the motor's electrical wires. For motors controlled by a variable frequency drive (VFD), data calculated by the VFD can be used instead of sensors. 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 Figure 11 As shown, the end of the pool 64 facing the chamber can be separated by the chamber by a width WW. In an exemplary embodiment, the spacing between the chamber and the pool allows for observation by a bystander. As shown, the space between the pool 64 and the chamber 62 includes a floor 78 where an observer can stand. The floor may be located around the water level of the pool 64 or at a higher position to provide a better view for surfers in the area adjacent to the chamber or the rest of the pool. This area may include a bleacher 76 or other seating area or walkway to allow pedestrians or observers to pass by or observe activities within the pool.

[0105] In exemplary embodiments, the space between the chamber and the pool, in addition to or replacing observer observation, may allow for the storage of system components. For example, the area between the pool 64 and the chamber 62, located above the flow channel 66, may include space for an air pressurization chamber, pump equipment, blowers, electronics, controllers, equipment rooms, or other system components. As shown, the grandstand or seating area may include an equipment room 86. The space below the floor 78 or located between the chamber and the pool may include other component portions, such as space for an air pressurization chamber, electronics, controllers, or other equipment. As shown, the area between the pool and the chamber includes space for an air pressurization chamber 84, and an electrical room is located behind the chamber 86.

[0106] In an exemplary embodiment, the space between pool 64 and area 72 between the pool and 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, wall 74 may extend beyond the height of the water to separate the space between the pool and chamber from the pool itself. Wall 74 may be a pool-side extension above the flow channel inlet. Wall 74 may be acrylic, plastic, or other translucent or transparent material to allow observation of activities in the pool from a location outside the pool. Wall 74 can protect observers from getting wet or accidentally falling into the pool.

[0107] The exemplary embodiments described herein may include unique pool constructions for managing water flow to influence the flow. Such exemplary constructions can be used to generate and maintain desired wave formation and allow wave shapes to form continuously or temporally repeatingly along the length of the pool to minimize the elapsed time between wave formations. Therefore, exemplary embodiments may include lagoons and channels located at the shallow end of the pool to guide water at the end of the waves. The lagoon or channel can be used to absorb and dissipate water flow within the pool.

[0108] As previously mentioned Figure 1A The exemplary wave pool generator may include a pool area and one or more chambers for generating waves within the pool area. Waves 16 may propagate away from the chambers and toward the end of the pool. The end of the pool may be formed by a sloping bottom to simulate a beach area. As water is propelled through the pool area by releasing water from the chambers, it may travel toward the end, through the sloping bottom, and upwards along the sloping bottom until it stops and eventually returns to the pool area along the sloping bottom under the influence of gravity. However, the water returning to the pool may create a flow that interferes with the generation of repeating waves. Therefore, the exemplary embodiment may include additional water features to handle the movement of the water.

[0109] Figure 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 may be created by a pool floor that gradually narrows upwards, such that the water level of the pool area 181 is in contact with the pool floor. The incoming waves 182 push water upwards onto the shore area 185, such that the point where the water meets the shore changes with the wave's progression. Therefore, the shore area 185 may include a high water level line 184, which may be the highest level (or further away from the chambers) that water can reach on the shore area 185 at a given wave progression. The high water level line 184 may depend on factors of the wave generating apparatus, including chamber release timing, pressure within the chambers, etc. A low water level line may be the location where water naturally rests on the waveless pool floor along the shore area 185, or the lowest point where water rests when waves are generated (closest to the chambers).

[0110] The exemplary embodiments described herein may include a pool or trough, wherein the pool floor reaches the highest point in beach area 185. The floor may then gradually move away or lower, allowing water to be trapped in a second pool area 183. The second pool area 183 may be shallow to form a wading pool or lagoon, or it may be deeper to form a channel or ditch guiding water. The second pool area 183 may be used to trap water from pool area 181 that has crossed beach area 185 and entered the second pool area 183 due to waves 182. This water trapping reduces water returning to pool area 181 and reduces the adverse effects of water flow generated from backflow.

[0111] Before transitioning to the second pool area 183, the highest point of the beach area may occur between, adjacent to, at, or along the low and high water lines of pool area 181. For example, as shown, the highest point of the beach area on the lateral outer edge of beach area 185 may be adjacent to or within the low water line, allowing pool area 181 and the second pool area 183 to be fluidly connected regardless of wave generation. The highest point of the beach area facing the center of the pool may be located externally or at the high water line 184, allowing pool area 181 and the second pool area 183 to be separated by a gap 186 in the raised floor, thus enabling fluid communication between the pools without passing through this gap (but allowing passage along other areas of the beach area). The highest point of the beach area may also be located between the low and high water lines, allowing pool area 181 and the second pool area 183 to be partially fluidly connected along the beach area only when waves are generated and propagate through the beach area. In this case, the water is captured when it is pushed ashore and does not return directly to pool area 181 from the outlet location.

[0112] like Figure 12As shown, a combination of relative positions and spacings between the first pool area 181 and the second pool area 183 can be used. As illustrated, the first and second pool areas are fluidly connected along the length of the beach area from the outer edge toward the center 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 or between the low water level and the high water level. 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, such that the highest height of the pool floor between the first pool area 181 and the second pool area 183 along this gap is approximately equal to or higher than the high water level.

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

[0114] Exemplary embodiments of the wave generating device may include a beach area 188 adjacent to a second pool area, lagoon, or other water feature in which water may be inaccessible and onlookers may gather. Other observation areas 189 may be provided along other sides of the wave generating device, such as on the lateral side of the pool area 181.

[0115] Exemplary embodiments may therefore include a pool configuration in which wave energy flows into a second pool area at a floor height corresponding to a desired water level (e.g., the low water line). The second pool area may be a deeper lagoon or channel. The second pool area may be configured to absorb and dissipate water flow from the main pool or the pool used to generate waves. In an exemplary embodiment, the main pool and the secondary pool may be fluidly connected via deep-water channels, thereby maintaining the water levels of the main pool and the secondary pool at equal heights without the need for buffer tanks or pumps.

[0116] Figure 13An alternative pool configuration is shown, having a first pool area 191 and a second pool area 193 to dissipate energy generated by waves 192. As waves are generated and dissipate along beach area 195, the main or first pool area 191 may include a low water level and a high water level. A desired water level 194 can be selected, wherein the first pool area 191 and the second pool area 193 are fluidly connected. This desired water level 194 may lie along the length of the beach area at, below, between, or a combination thereof, the low water level and the high water level. This desired water level 194 may correspond to the highest point of the pool floor at the point between the first and second pool areas. Similar to... Figure 12 As explained, gap 196 may be formed along the length of the beach area between a portion of the first pool area 191 and the second pool area 193.

[0117] Figure 13 An embodiment could create a larger lagoon area at the opposite end of beach area 195, adjacent to the lateral side of main pool 191. The second pool area could therefore include an incline extending into main pool area 191. The second pool area 193 could then create a channel toward 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 apparatus may include a deep-water return channel 197. The deep-water return channel 197 fluidly connects one or more second pools 193 to a main pool 191 located in a beach area 195 remote from the main pool. As shown, the deep-water return channel 197 extends below the beach area 195 of the first pool 191 to fluidly connect to the floor of the first pool 191 adjacent to or closer to the chamber than the beach area.

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

[0120] Figure 14An alternative pool configuration is shown, having a first pool area 111 and a second pool area 113 to dissipate energy generated by waves 112. As waves are generated and dissipate along beach area 115, the main or first pool area 111 may include a low water level (L) and a high water level (H). A desired water level 114 may be selected, wherein the first pool area 111 and the second pool area 113 are fluidly connected. This desired water level 114 may lie along the length of the beach area at, below, between, or a combination thereof, the low water level and the high water level. This desired water level 114 may correspond to the highest point of the pool floor at the point between the first and second pool areas. Similar to the illustration in Figure 9, a gap 116 may be formed along the length of the beach area between a portion of the first pool area 111 and the second pool area 113.

[0121] exist Figure 14 In an exemplary embodiment, water from one or more second pools may be removed from the wave-generating device or the main pool 111. In this case, the water may be directed to a collection tank or other water feature, such as a lazy river or wading pool. In an exemplary embodiment, the other water body may have a lower static water level to allow water to drain from the one or more second pools or channels formed therefrom and enter the other water body. In an exemplary embodiment, water from the other water body 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 construction or other water feature characteristics.

[0122] In an exemplary embodiment, the second pool area 113 may be covered. The second pool area comprises deeper channels that trap water as it overflows from the main pool 111 during waves. The second pool area may be covered by a porous floor, allowing water to pass through the openings, 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 an area for absorbing water. Instead, the second pool area may be located below the beach area.

[0123] The exemplary embodiments provided herein include a wave generating device, wherein wave energy can surge onto a static water level separator and flow into one or more second water tank areas. Therefore, water can be discharged to a collection tank or other water structure at a static water level lower than that of the main water tank. Subsequently, water can be pumped back from the tank or component to maintain the operating water level.

[0124] Figure 15An alternative pool configuration is shown, having a first pool area 1111 and a second pool area 1113 to dissipate energy generated by waves 1112. As waves are generated and dissipate along a beach area 1115, the main or first pool area 1111 may include a low water level (L) and a high water level (H). A desired water level 1114 may be selected, wherein the first pool area 1111 and the second pool area 1113 are fluidly connected. The desired water level 1114 may lie along the length of the beach area at, below, between, or a combination thereof, the low water level and the high water level. The desired water level 1114 may correspond to the highest point of the pool floor at a point between the first and second pool areas. In this exemplary embodiment, the ideal water level 1114 lies at or below the low water level for a portion of the length of the beach area and is substantially equal to the high water level for another portion of the length of the beach area. In an exemplary embodiment, the desired water level may be located at the low water level or along the entire length of the beach area between the low water level and the high water level, such that no gap is created between the first pool and the second pool, or only a temporary gap is created between the first pool and the second pool during water production.

[0125] like Figure 15 As indicated by the arrows, water flow in one or more second pools may be directed toward the lateral end of a beach area opposite the lateral side of the main pool 1111. The second pool 1113 may extend along the side of pool 1111 and may be in fluid communication with the first pool 1111. In an exemplary embodiment, the bottom of the main pool 1111, or along the lower edge of the lateral sidewall or through the floor of pool 1111, may include a grid or perforations to fluidly connect to the second pool 1113. Water may return to the first pool 1111 through the lower part or bottom of the first pool 1111.

[0126] The exemplary embodiments described herein may include wave generating devices, wherein wave energy may be flushed across a separator at a desired water level and enter a secondary pool. The secondary pool may include a channel with a cover. The cover may allow water to pass through the cover, but not people or body parts. In an exemplary embodiment, the cover may conceal the channel within a beach area of ​​the first pool. In an exemplary embodiment, the water flow in the channel may be weakened. The channel and the first pool may be fluidly connected through openings at the bottom of the pools, thereby allowing the two bodies of water to maintain the same water level without pumping. Users and customers may also walk over the cover of the channel.

[0127] This document provides exemplary constructions of systems and methods for dissipating wave energy and controlling water flow in a main pool. Illustrative combinations are provided by way of example only. Any exemplary feature may be used in any combination of other exemplary features. For example, any representative example may include a shallow, open pool that can function as a wading pool or lagoon as a second pool. Any representative example may include a covered channel such that the second pool does not generate an active portion. 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 assist fluid flow and move water in a desired direction. Any representative example may have a first pool and a second pool in fluid communication throughout the wave generation period. Any representative example may have a desired waterline of any construction 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 waterline and enter the second pool. For example, any representative example could be that the desired water level is positioned along the length between the first pool and one or more second pools below the low water level, approximately equal to the low water level, between the low water level and the high water level, or above the high water level, or any combination thereof.

[0128] The 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 transverse sidewalls extending from the ends of the first linear wall at an inclined angle.

[0129] Exemplary embodiments may also include a pool wave generator having pool areas and any method for generating waves to propagate through the pool areas. The pool wave generator may also include one or more second pool areas. The first and second pool areas may be separated by a separator having a desired water level height. The height of the separator may vary along the length of the separator between the first and second pool areas. The height of the separator may be at a low water level height of the pool area during wave generation, at a static water level height of the pool area when no waves are generated, at or above a low water level height of the pool area during wave generation, below a high water level height of the pool area during wave generation, and combinations thereof.

[0130] A second pool can be located between the pool area and the chamber. The second pool can be configured to form a channel of length for water to travel laterally through the pool area, and to minimize the amount of water returning to the pool at the outlet location of the water leaving the pool area after a wave. The second pool can be positioned to receive water leaving the pool area during a wave, so as to minimize the direct return of water to the pool area.

[0131] The second water tank area can be fluidly connected to the first water tank area through a deep water channel located below the bottom of the first water tank area.

[0132] 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 laterally around the pool area. The channel may be configured to reintroduce water into the pool area from the channel at the bottom of the pool area.

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

[0135] Figure 16 It shows something similar to Figure 4 A portion of the exemplary floor bottom. As shown, the pool floor may include a return channel 1201 located at the center of the pool. The return channel may be a floor profile to facilitate water flow from a first or second pool as described herein. For example, the exemplary floor may include a continuous, gradually narrowing region to allow a smooth, horizontal transition back into the pool. The return channel 1201 may promote a phenomenon similar to eddies. All or part of the return channel 1201 may be located at one or more positions or along one or more lengths at a lower height relative to the pool floor on opposite lateral sides of the return channel.

[0136] Figure 17 This indicates a valve assembly comprising 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 intermediate position, wherein the valve position is provided to the actuator controller by a signal from the main controller. The actuator's response to the signal can be tuned via the actuator controller. Figure 17 As shown, valve 1702 is fully open.

[0137] Figure 18 Typical throttle valve characteristics are shown, illustrating how the pressure drop across the valve or throttle valve increases with increasing opening degree. By controlling the valve opening degree, one can control the pressure drop across the valve and the amount of air transmitted through it.

[0138] Figure 19 This is a block diagram describing the calculation of the valve opening degree required to meet a target water level. It illustrates a controller method for calculating the valve opening degree based on the target water level, the current water level in the chamber, the pressure in the chamber, the temperature in the pressurization chamber, the power consumed by the fan motor, and the temperature and humidity of the mechanical chamber, using well-known laws of fluid dynamics. set This is the target height received from the user interface. Z w It is the actual water level height measured by the sensor. The error is given by e. in It means, e in It is Z set and Z w The difference between the two values ​​is used to calculate the angle required to reach the target, which is then used to send a signal to the actuator to open the valve to the appropriate degree. This process is repeated as the system continuously measures, recalculates, and adjusts as needed.

[0139] Figures 20A-20D It shows in Figure 19 The locations of valves and the water levels in the system and method at each of points 1, 2, and 3 shown. Although some sensors are shown and described in these figures, additional or alternative sensors may be used as stated above.

[0140] Figure 21 The water level evolution in different chambers is illustrated. 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 towards the left side of the pool, while the second wave moves generally towards the right side. This invention allows for the ability to target different water level heights within the chambers, thus allowing the chambers to generate waves of different sizes simultaneously. For example, a more skilled surfer might require larger waves, while a novice surfer in the same pool might require smaller waves. Figure 21 This scenario is depicted, 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] Figure 22 A method for generating waves with a maximum amplitude greater than the normal possible amplitude for a given device setting is illustrated. In this method, the height of the water in a control chamber is increased, allowing the system to generate an initial, small-amplitude wave (excitation) to move the water, thereby generating larger waves thereafter. Figure 22As shown, the dashed line represents the maximum wave amplitude of a given system. Compared to an uncontrolled method, the maximum wave height can be increased by 25%, causing waves to exceed the normal maximum amplitude. Also as mentioned above, when the valve is used in this configuration, such that it is configured to transition between fully closed and fully open states, the air within the chamber can act as a spring. When the water in the chamber reaches its maximum or minimum height, the water level can rebound as the air is compressed and released, thus generating an oscillating wave surface.
