DETAILED DESCRIPTION

[0053] Some embodiments include an activity pool that can have a number of different functions or configurations. In some embodiments, an activity pool may include an axial flow pump that is not submersed within the water and can direct water from a reservoir, through an intake, and out an output nozzle. The output nozzle may further include a water pressurizer, which may increase pressure in the output nozzle, before directing the water into the channel. Some embodiments may include a detachable or removable wave form that can be disposed within an activity channel.

[0054] For example, water may be stored in a water reservoir. An axial flow pump may include an intake in communication with the water reservoir and houses an impeller and shaft coupled with a motor. The intake may include one or more guide vanes oriented generally parallel or off-axis relative to an axis of the intake. The guide vanes, for example, may be configured to reduce turbulence of water and/or water rotation as it flows through the intake. When the axial flow pump is active, the axial flow pump may direct water from the water reservoir, through the intake, and out the output nozzle. The output nozzle can expand laterally and/or vertically for a first distance from the intake and then contract laterally and/or vertically for a second distance from the first distance to a channel. In some embodiments, water may flow from the output nozzle into the activity channel. The water may approach a wave form in the channel, which disturbs a flow of the water such that the water forms a wave in the channel. The water flows through the channel to a return, which directs the water to the reservoir.

[0055] FIG. 1 is an illustration of a perspective view of an activity pool 100 according to some embodiments. The activity pool 100 may include a water reservoir 110, an axial flow pump housing 120, an outlet nozzle 130, one or more water return channels 140, and an activity pool reservoir 150. In some embodiments, water may be pumped from the water reservoir 110, through an intake in an axial flow pump 160 disposed within the axial flow pump housing 120, out the outlet nozzle 130 into an activity channel 155 of the activity pool reservoir 150. Water may return to the water reservoir 110 from the activity pool reservoir 150 via the one or more water return channels 140. In some embodiments, the axial flow pump 160 may pump water into the activity channel 155 of the activity pool reservoir 150 with a variable flow rate. In other words, the flow may be adjusted based on a user selected activity.

[0056] In some embodiments, the activity pool 100 may include one or more drain gates disposed between the activity pool reservoir 150 and the one or more water return channels 140. Water can flow from the activity pool reservoir 150 back to the water reservoir 110 via the water return channels 140.

[0057] In some embodiments, water return channels 140 may be disposed on one or both sides of the activity pool reservoir 150 and/or the back of the activity pool reservoir 150. The return channels 140 may be fluidically coupled with the water reservoir 110. Water can flow from the activity pool reservoir 150 back to the water reservoir 110 via the water return channels. In some embodiments, the water return channels 140 may include grates at the top surface of the water return channels 140. The grates, for example, may be made from fiberglass, ABS plastic, metal, composites, plastics, etc.

[0058] In some embodiments, the activity channel 155 may have longitudinal side walls that span a portion or all of the activity channel 155 from an end proximate to the outlet nozzle 130 to a distal end of the activity channel 155 opposite the outlet nozzle 130. The activity channel 155 may have an activity deck which can be adjusted to various heights to create various depths of water in the activity channel 155. The position of the activity deck may be described as a height (e.g., relative to a bottom surface of the activity pool reservoir 150) or a depth (e.g., relative to a water surface level within the activity pool reservoir 150). In some implementations, the activity channel 155 may have a bottom surface may have a sloped portion at or near the distal end of the activity channel 155.

[0059] The activity pool reservoir 110 may include an upper portion, a sloped portion and a lower portion. The bottom of the upper portion may be level with the bottom of the activity pool reservoir 150. This can, for example, guide water in the activity pool reservoir 110 toward the bell end 310 at the lower portion of the axial flow pump. In some embodiments, the activity pool reservoir 110 may be adjacent to the water return channel 140, rather than directly below the water return channel 140.

[0074] In some embodiments, each of a plurality of vertical lifting screws may be coupled with a bottom of the activity deck 230 and a corresponding one of the plurality of lifts 240. Each of a plurality of vertical lifting screws may be threaded and/or may move vertically from the bottom 270 of the activity pool reservoir 150 to the top surface 210 of the activity pool 100. The top of each of the plurality of vertical lifting screws may be attached with the bottom of the activity deck 230 such as, for example, via an load pad that rotates relative to the vertical lifting screw. The plurality of lifts 240 may rotate each of the vertical lifting screws causing the top of the vertical lifting screw to travel upwards or downwards.

[0075] FIG. 8 is a top view of the activity pool 100 with the plurality of lifts 240 arranged in an H-configuration on the side of the activity deck 230 according to some embodiments. In the H-configuration, the motor 605 may be coupled with lift 240A and 240B of the plurality of lifts 240 such as, for example, via a worm gear. The lift 240A may be coupled with lift 240C and 240E such as, for example, via two different worm gears.

[0078] In some embodiments, each of a plurality of vertical lifting screws may be coupled with a side of the activity deck 230 and a corresponding one of the plurality of lifts 240. Each of a plurality of vertical lifting screws may be threaded and/or may extend from the bottom 270 of the activity pool reservoir 150 to the top surface 210 of the activity pool 100. Each of the plurality of vertical lifting screws may be attached with a side of the activity deck 230 via a threaded attachment mechanism. The plurality of lifts 240 may rotate each of the vertical lifting screws causing the threaded attachment mechanism to travel upwards or downwards.

[0079] In some embodiments, a sensor may determine the vertical height of the activity deck 230. The sensor, for example, may be disposed within the plurality of screw jack system and may measure rotations corresponding to an activity deck height. The sensor, for example, may be disposed within the activity deck and measures vertical distance relative to the side of the pool or the bottom 270 of the activity pool reservoir 150 or the top surface 210 of the activity pool 100. The sensor may send a signal to a controller indicating the height of the activity deck 230. The controller, for example, may adjust the speed of water flow produced by the axial flow pump 160 based on the height of the activity deck.

[0080] For example, when the activity deck 230 is set to a height configured for surfing (e.g., as shown in FIG. 6), the speed of the axial flow pump may increase with an increased depth of the activity deck 230. The options of the different configurations may allow the user to customize the height of the activity deck 230 and speed of water produced by the axial flow pump 160 depending on the specific type of activity they choose.

[0081] Although six lifts are shown in some of the figures and described above, any number of lifts may be used without limitation. Moreover, these lifts may be arranged in any manner and in any configuration without limitation.

[0082] The lifts shown in some of the figures and described above, may include any type of lift may be used such as, for example, screw jacks, scissor lifts, hydraulic lifts, and/or cable and pulleys. Any other type of lift may be used.

[0083] FIG. 10 is a side view of an axial flow pump 160 according to some embodiments. The axial flow pump 160 may include an axial housing that includes a water flow channel 320, a nozzle 130, a bell end 310, a bottom portion 311, and a apertures 312. The bell end 310, for example, may be located near the bottom of the axial flow pump housing. The axial flow pump housing, for example, may include a plurality of apertures 312 through which water may be pulled from the water reservoir 110 and may be pumped out the nozzle 130. These apertures, 312 for example, may be found within the bottom portion 311 and/or the bell end 310.

[0084] In some embodiments, the axial flow pump housing can be shaped with a bell end 310. The bell end 310 may be shaped to improve water flow into the axial flow pump housing. For example, the bell end 310 may improve uniformity of the water as water enters the axial flow pump housing from the water reservoir 110. The axial flow pump housing may also include guide vanes 410 as shown in FIG. 12. In some embodiments, the guide vanes 410 may extend along an axis of the axial flow pump housing that is generally in the path of the water when the axial flow pump is in operation. The guide vanes 410, for example, may include any number of vertical components. The guide vanes 410, for example, may include between 3 and 6 vertical components. The guide vanes 410, for example, may be coupled to an inner surface of an wall of the axial flow pump housing. The guide vanes 410, as another example, may not be coupled to the inner surface of the wall of the axial flow pump housing. The guide vanes 410, for example, may interact with an element of the inner surface of the out wall of the axial flow pump housing such that the guide vanes are restricted from rotating.

[0085] In some embodiments, the bell end 310 may be elevated from a floor of the water reservoir 110 by one or more supports or the bottom portion 311. The one or more supports may couple the axial flow pump housing to the water reservoir 110 via horizontal components and/or vertical components. Additionally or alternatively, the axial flow pump housing may be mounted to a cap of the water reservoir 110 (e.g., via the axial flow pump housing) and/or suspended above the floor of the water reservoir 110.

[0086] In some embodiments, the bell end 310 may have generally smooth curve along an edge of its cross section. In some embodiments, the bell end 310 may be implemented with any shape that narrows along an axis that generally follow the flow of water through the axial flow pump housing. In some embodiments, water may enter the bell end 310 from all 360 of the surface of the bell end 310. This could possibly help reduce vortices and turbulence in the water. The bell end 310 may be shaped like a bell and/or may have a diameter that is larger than the diameter of the water flow channel 320. In some embodiments, the bell end 310 may include grooves on the inside of the bell end 310, which may possibly reduce the rotational influence of the axial flow pump.

[0087] FIG. 11 is an illustration of an example axial flow pump motor 330 and impeller 430 according to some embodiments. In some embodiments, the axial flow pump motor 330 may be coupled with the impeller 430 via a drive shaft 420. In some embodiments, the axial flow pump may include a shaft seal to maintain a seal between the axial flow pump motor 330 (e.g., at the drive shaft 420) and a surface of the axial flow pump housing. The axial flow pump motor 330 may also include one or more reduction gears. The one or more reduction gears may be used to adjust a rotation rate of the drive shaft 420 and impeller 430.

[0088] The axial flow pump motor 330 may be configurable for operation at multiple speeds, which may be characterized by a rotation speed of the impeller 430 such as, for example, a volume per second of water that is driven through the intake, or a linear speed of water as it the axial flow pump propels the water through a portion of the axial flow pump housing, nozzle 130, or water flow channel 320.

[0089] The axial flow pump motor 330 may be a combustion engine or an electrical engine. In some implementations, the axial flow pump motor 330 may be powered via a connection to a battery, which may in turn be charged via a renewable power supply such as a solar panel. The axial flow pump motor 330 may be positioned above an upper surface of the axial flow pump housing and/or above the water surface 220.

[0090] In some embodiments, the axial flow pump motor 330 may be positioned to the side of the axial flow pump housing.

[0091] The drive shaft 420 may extend along a path of the water flow when the axial flow pump is in operation. The drive shaft 420 may extend along a path of the water flow through one or more of the plurality of portions.

[0092] The impeller 430 may be attached to the drive shaft 420, which may rotate to spin the various blades 435 of the impeller 430. The drive shaft 420 may extend from a hub of the impeller 430, through the intake and to the axial flow pump motor 330. In some embodiments, the drive shaft 420 may extend past a bulkhead at an end of axial flow pump housing, through a shaft seal, and to the axial flow pump motor 330. In some embodiments, the blades 435 of the impeller 430 may be attached to an impeller hub and extend outwardly toward an inside wall of the axial flow pump housing. The blades 435 may be shaped so that the impeller provides thrust on the water when rotated to draw water further into the axial flow pump housing. For example, the impeller may direct water along a path that is generally parallel with the drive shaft 420.

[0093] In some embodiments, the diameter of the impeller 430 may be about the same diameter as an inner diameter of the axial flow pump housing and/or an inner diameter of the water flow channel 320 and/or an inner diameter of the axial flow pump housing. In some embodiments, the impeller 430 may be shaped to create a force on the water that draws it at least partially in a vertical direction and further into the axial flow pump housing. In some embodiments, the impeller 430 may draw the water in a horizontal direction or another direction that influences the water to be drawn farther into the axial flow pump housing. The impeller 430 may, for example, have a bell-shaped dome on the bottom side and/or directly over the hub to help draw the water more efficiently around the impeller 430 and into the axial flow pump housing. The impeller 430 may, for example, be flat or have another shape that may help draw water around the hub and into the axial flow pump housing.

[0094] In some implementations, the axial flow pump 160 may be coupled with a controller that can control the speed of the axial flow pump motor 330. The controller may control power or to the axial flow pump such that it achieves the requested operational speed. For example, the controller may receive an input requesting a flow rate of 20 cubic feet per second. The controller may increase or decrease power to the axial flow pump until the controller receives input (e.g., from a sensor within the wave flow apparatus). Alternatively, the controller may receive an input to increase or decrease a flow rate, responsive to which the controller correspondingly increases or decreases power to the axial flow pump.

[0095] FIG. 12 is an illustration of a guide vane structure 410 that may be disposed within the axial flow pump housing according to some embodiments. In some embodiments, the guide vane structure may be in positional context with an optional bell end 310, the impeller 430, and/or the drive shaft 420.
