Abstract
Description
Technical Field
[0001] This application relates to the field of pool surfing technology, specifically to a flow channel structure for a pool surfing device and a pool surfing device. Background Technology
[0002] To enhance pool entertainment, users often add surfers that generate high-volume jets of water. Right-angled flow channels are a common design in surfers, where the water inlet and outlet are at a 90° angle. Specifically, water is propelled into the channel from below by a motor propeller, flows vertically upwards through a rectifier channel, and then exits from a 90° bend.
[0003] Given a fixed water spray volume, the outlet water velocity and range are important evaluation indicators affecting user experience. (Refer to...) Figure 1 The existing surfer has a right-angled flow channel with a large inlet and a small outlet (i.e., the cross-sectional area of the inlet is larger than that of the outlet). Although this structure can increase the flow rate, the small area of the outlet reduces the range of water flow.
[0004] Along the direction of water flow within the channel, from the inlet 11 to the outlet 12, the cross-sectional area of the channel gradually decreases. Therefore, the direction of water flow at different locations will also be different. Figure 1 The arrows in the diagram indicate the direction of water flow at certain locations, with the water flow velocity reaching its maximum at the outlet. At this point, water flows in different directions collide with each other, leading to increased turbulence and poor stability of the outlet velocity. Summary of the Invention
[0005] The purpose of this application is to overcome the deficiencies of the prior art and provide a flow channel structure and a pool surfer to solve the problems in the prior art.
[0006] To address the aforementioned issues, a first aspect of this application provides a flow channel structure for a pool surfer, comprising a housing. The housing includes a first component and a second component. The first component has a first flow channel for draining water, and the second component has a second flow channel for inlet water. The first flow channel and the second flow channel are interconnected.
[0007] The first flow channel has a rectangular cross-section, and the second flow channel has a circular cross-section;
[0008] The first flow channel is provided with a flow branching structure, which is used to form multiple branch channels with the same flow rate;
[0009] The second flow channel is provided with a flow rectification structure, which is used to rectify the flow to eliminate eddies.
[0010] In one possible implementation, the first flow channel includes an upper wall surface and a lower wall surface, both of which include arcuate curved surfaces.
[0011] The flow diversion structure includes a plurality of flow guide plates, which are located between the upper wall and the lower wall.
[0012] Each of the aforementioned guide plates is spaced apart from the upper wall surface and the lower wall surface, and each of the aforementioned guide plates has a branch channel on both sides in the thickness direction;
[0013] The side of the guide plate closest to the upper wall is the upper guide surface, and the side closest to the lower wall is the lower guide surface; the upper guide surface and the lower guide surface are respectively located on both sides of the thickness direction of the guide plate; wherein, the upper guide surface and the lower guide surface are both arc-shaped curved surfaces.
[0014] In one possible implementation, the first flow channel further includes a first side wall and a second side wall arranged in parallel, wherein the upper wall, the first side wall, the lower wall and the second side wall are sequentially connected and enclose to form the first flow channel;
[0015] The two sides of the guide plate in the width direction are respectively sealed and connected to the first side wall and the second side wall.
[0016] In one possible implementation, one end of the guide plate extends toward the drainage side of the first flow channel in the longitudinal direction, and the other end extends toward the second flow channel.
[0017] In one possible implementation, the curvature of the deflector is 60–90°.
[0018] In one possible implementation, the rectifier structure includes a plurality of rectifier guide vanes arranged in a ring array;
[0019] The end of the second flow channel closest to the first flow channel is the end of the second flow channel, wherein the rectifier guide vane is disposed at the end of the second flow channel.
[0020] In one possible implementation, an impeller is provided in the second flow channel, and the impeller is mounted on the drive shaft of a drive motor, wherein the drive motor is located outside the housing.
[0021] In one possible implementation, both the drive motor and the housing are fixed to a mounting bracket.
[0022] In one possible implementation, the housing includes a water inlet and a water outlet, the central axes of which are perpendicular to each other; wherein the water inlet is located at the end of the second flow channel and the water outlet is located at the end of the first flow channel;
[0023] The cross-sectional areas of the water inlet and the water outlet are the same.
[0024] A second aspect of this application provides a pool surfer, including a drive device and a flow channel structure as described above; wherein the drive device is used to drive water to flow within the flow channel of the flow channel structure.
[0025] The beneficial effects of this application include at least the following:
[0026] The flow channel structure for a pool surfer proposed in this application includes a shell, a first flow channel disposed within a first component of the shell, and a second flow channel disposed within a second component. Water enters through the second flow channel and flows out through the first flow channel.
[0027] The first flow channel is equipped with a diversion structure to form multiple branch channels with consistent flow rates. This ensures that the outflow velocities of each branch channel are similar, thereby reducing turbulence and improving the stability of the outflow velocity without reducing the overall flow rate. The first flow channel has a rectangular cross-section, which facilitates the installation of the diversion structure to obtain multiple branch channels with consistent flow rates.
[0028] The second flow channel is equipped with a flow-rectifying structure to eliminate eddies. The cross-section of the second flow channel is circular. Because a circular cross-section has no sharp corners, it reduces water separation at corners, lowers local resistance losses, and also reduces eddies.
[0029] This flow channel structure has advantages such as flow rectification and vortex reduction, turbulence reduction, and stable water outlet velocity. Attached Figure Description

[0042] Example
[0043] like Figure 2 and Figure 3 As shown, in this embodiment, a flow channel structure for a pool surfer is proposed, including a housing 100. The housing 100 includes a first component 110 and a second component 120. The first component 110 is provided with a first flow channel 130 for drainage, and the second component 120 is provided with a second flow channel 140 for water inlet. The first flow channel 130 and the second flow channel 140 are interconnected. Figure 3 The dotted lines in the diagram do not exist in the actual product; they are only for easy distinction between the first flow channel 130 and the second flow channel 140. The first flow channel 130 and the second flow channel 140 are connected by an intermediate flow channel 150.
[0044] The first component 110 can be a square curved cylinder, and the second component 120 can be a circular straight cylinder.
[0045] The first flow channel 130 has a rectangular cross-section, and the second flow channel 140 has a circular cross-section.
[0046] A diversion structure 200 is provided within the first flow channel 130, which is used to form multiple branch channels 201 with consistent flow rates. Consistent flow rates mean that the flow rates of each branch channel 201 are the same or the difference is within a certain range.
[0047] A rectifier structure 300 is provided inside the second flow channel 140. The rectifier structure 300 is used to rectify the flow and eliminate eddies.
[0048] After the pool surfer is started, the water in the pool enters the flow channel structure through the second flow channel 140, and then exits through the first flow channel 130, thus forming a water flow field.
[0049] A diversion structure 200 is provided within the first flow channel 130 to form multiple branch channels 201 with consistent flow rates. This ensures that the outflow velocities of each branch channel 201 are similar, thereby reducing turbulence and improving the stability of the outflow velocity without reducing the overall flow rate. The first flow channel 130 has a rectangular cross-section, which facilitates the installation of the diversion structure 200 to obtain multiple branch channels 201 with consistent flow rates.
[0050] A flow-rectifying structure 300 is provided inside the second flow channel 140. The flow-rectifying structure 300 is used to rectify the flow and eliminate eddies. The cross-section of the second flow channel 140 is circular. Since the circular cross-section has no sharp corners, it can reduce the separation of water flow at corners, reduce local resistance loss, and reduce eddies.
[0051] This flow channel structure has advantages such as flow rectification and vortex reduction, turbulence reduction, and stable water outlet velocity.
[0052] The first flow channel 130 includes an upper wall surface 131 and a lower wall surface 132, both of which include arc-shaped curved surfaces. The upper wall surface 131 is an arc-shaped curved surface; the portion of the lower wall surface 132 near the second flow channel 140 is an arc-shaped curved surface, while the portion extending to the drain outlet 102 is a flat surface.
[0053] The flow divider structure 200 includes several guide vanes, which are located between the upper wall surface 131 and the lower wall surface 132.
[0054] In this embodiment, one guide vane is used to divide the first flow channel 130 into two almost equal parts, thus obtaining two branch channels 201 with the same flow rate. In other embodiments, the number of guide vanes can be set as needed, such as two or three. In this case, multiple parallel guide vanes can be used to divide the first flow channel 130 into multiple branch channels 201 with the same flow rate.
[0055] Since the cross-section of the first flow channel 130 is rectangular, it is very convenient to determine the installation position of the guide vane and to install the guide vane.
[0056] Each guide vane is spaced apart from the upper wall surface 131 and the lower wall surface 132, and each guide vane has a branch channel 201 on both sides in the thickness direction. When there is one guide vane, there are two branch channels 201; when there are two guide vanes, there are three branch channels 201, and so on. In some embodiments, when there are multiple guide vanes, the guide vanes may be arranged parallel to each other and at equal intervals.
[0057] The side of the guide vane closest to the upper wall surface 131 is the upper guide surface 210, and the side closest to the lower wall surface 132 is the lower guide surface 220. The upper guide surface 210 and the lower guide surface 220 are located on opposite sides of the guide vane in the thickness direction. Both the upper guide surface 210 and the lower guide surface 220 are curved surfaces and can have the same curvature.
[0058] The first flow channel 130 also includes a first side wall 133 and a second side wall that are parallel and opposite to each other. The upper wall 131, the first side wall 133, the lower wall 132, and the second side wall are connected in sequence and enclose each other to form the first flow channel 130. Due to the perspective, the second side wall is not shown in the attached drawings.
[0059] The two sides of the guide plate in the width direction are respectively sealed to the first side wall 133 and the second side wall. The sealing connection can be achieved by welding or sealant.
[0060] One end of the guide plate extends toward the drainage side of the first flow channel 130 (i.e., the drainage port 102 of the flow channel structure); the other end extends toward the second flow channel 140, specifically, into the intermediate flow channel 150.
[0061] In this embodiment, the curvature of the deflector is 60–90°.
[0062] The rectification structure 300 includes multiple rectification guide vanes arranged in a ring array, with a rectification space formed between two adjacent rectification guide vanes. The end of the second flow channel 140 closest to the first flow channel 130 is the end of the second flow channel 140, wherein the rectification guide vanes are disposed at the end of the second flow channel 140.
[0063] The rectifier guide vane is fixedly installed inside the second flow channel 140. One side of the rectifier guide vane is fixed and sealed to the inner wall of the second flow channel 140, and the other side is fixed and sealed to the side wall of the central column 310.
[0064] An impeller 410 is installed inside the second flow channel 140. The impeller 410 is mounted on the drive shaft of the drive motor 420, which is located outside the housing 100. The impeller 410 is closer to the inlet 101 than the rectifier guide vanes.
[0065] Reference Figure 3 When the pool surfer is started, the drive motor 420 begins to work, thereby driving the impeller 410 to rotate. The rotating impeller 410 draws water from the pool into the second flow channel 140. The water entering the second flow channel 140 will rotate violently due to the action of the impeller 410, thus forming a vortex. After the rotating water flows into the rectification space, its rotation speed will gradually decrease due to the obstruction of the rectification guide vanes, thereby achieving rectification and eliminating vortices. Subsequently, the water flows through the middle flow channel 150 into the first flow channel 130. During this process, under the action of the guide plate, the water flow is divided into two streams: one stream flows in the branch channel 201 below the guide plate, and the other stream flows in the branch channel 201 above the guide plate. Due to the centrifugal force, the water in the lower branch channel 201 flows at high speed along the lower guide surface 220, and the water in the upper branch channel 201 flows at high speed along the upper wall surface 131. Thus, when the water is discharged from the drain outlet 102, it can have a high flow velocity, thereby obtaining a water flow field with greater impact force and a larger coverage area.
[0066] The cross-sectional areas of each branch channel 201 are approximately the same, and the water flow velocity in each branch channel 201 is also approximately the same. Therefore, the water flow rate of each branch channel 201 can be kept consistent.
[0067] Both the drive motor 420 and the housing 100 are fixed on the mounting bracket 430.
[0068] The housing 100 includes a water inlet 101 and a water outlet 102, the central axes of which are perpendicular to each other. (Refer to...) Figure 3 The central axis of the inlet 101 is parallel to arrow x, and the central axis of the outlet 102 is parallel to arrow y.
[0069] The centerline of the first flow channel 130 coincides with the guide plate. Specifically, both the centerline of the first flow channel 130 and the guide plate are arc-shaped, and their radii are the same. The radius of the centerline of the first flow channel 130 is not less than the diameter of the inlet 101, thereby ensuring that the water flow completes a 90° deflection with high efficiency.
[0070] The inlet 101 is located at the end of the second flow channel 140, and the outlet 102 is located at the end of the first flow channel 130.
[0071] The cross-sectional areas of the inlet 101 and the outlet 102 are the same; specifically, their cross-sectional areas are either identical or the difference is within a certain range.
[0072] like Figure 4 As shown, the cross-sections of inlet 101 and outlet 102 are stacked together, and their geometric centers coincide. Compared to inlet 101, outlet 102 has a smaller vertical dimension and a larger horizontal dimension. Because the first flow channel 130 changes in the corresponding direction compared to the second flow channel 140, this can increase the discharge velocity of the water flow to a certain extent. Combined with the centrifugal force mentioned above, this increases the drainage velocity of each branch channel 201.
[0073] In this embodiment, a pool surfer is also proposed, including a drive unit and the aforementioned flow channel structure. The drive unit is used to drive water to flow within the flow channel of the flow channel structure, wherein the drive unit includes an impeller 410 and a drive motor 420.
