Abstract
Description
Technical Field
[0001] This invention relates to the field of swimming training equipment technology, and in particular to a swimming training device and control method with adaptive flow rate adjustment function. Background Technology
[0002] Existing swimming training devices, especially counter-current swimming pools, infinity pools, and small home training pools, typically use water pumps, propellers, or jet components to create a training water flow towards the swimmer within the pool, enabling the swimmer to perform in-situ swimming training in a limited space.
[0003] In existing technologies, the adjustment of training water flow is mainly achieved by changing the output power, rotational speed, or flow rate of the propulsion module. That is, by increasing or decreasing the pump output intensity, the training water flow velocity is altered to adapt to the needs of different training subjects and training modes. However, this method still has certain shortcomings in practical applications: 1) In miniaturized swimming training devices with short pool lengths, the training water flow is output from the front end of the pool and flows to the tail end within a short path. The water at the tail end cannot be guided into the return path in time, which can easily cause stagnation, deceleration, accumulation, backflow, or local reverse disturbance in the tail area. This affects the tail boundary conditions of the main training flow, reduces the stability and continuity of the training water flow, and consequently affects the swimmer's training experience and training effect. 2) In existing technologies, the adjustment of training load mainly relies on the output adjustment of the propulsion module itself. Although the propulsion module can change the intensity of the training water flow, it essentially changes the input energy. When relying solely on the propulsion module for adjustment, the tail discharge capacity and tail boundary conditions of the main training flow are still difficult to control effectively. Especially when the tail discharge is not timely and the backflow disturbance is significant, the flow rate and energy output by the propulsion module are difficult to be effectively converted into a stable main training flow, thus limiting the effective improvement of the average flow velocity of the main training flow and resulting in a relatively simple training load adjustment method.
[0004] Therefore, it is necessary to provide a new swimming training device and control method with adaptive flow rate adjustment function to solve the problems of untimely pool tail discharge, difficulty in adjusting the boundary conditions of the main training stream tail, and single training load adjustment method in the existing technology. Summary of the Invention
[0005] The purpose of this invention is to solve the problems in the prior art, such as untimely drainage at the tail of miniaturized swimming pools, difficulty in adjusting the boundary conditions at the tail of the main training stream, and the single method of training load adjustment. Therefore, this invention proposes a swimming training device and control method with adaptive flow rate adjustment function.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a swimming training device with adaptive flow rate adjustment function, comprising: The pool body has an outlet on the upper side of the inner wall at the front end, a return water outlet on the lower side of the inner wall at the front end, and a tail drain outlet on the upper side of the inner wall at the tail end. A partition plate is disposed inside the pool body to divide the pool body into an upper training water area and a lower functional water area. A throttling window component is provided at one end of the partition plate near the drain outlet at the end of the pool. The upper training water area and the lower functional water area are selectively connected through the throttling window component. An adjustment mechanism, which is connected to the partition plate, is used to drive the partition plate to move vertically and to drive the throttling window assembly to open or close or adjust its opening. A propulsion module is located at the end of the pool body. The outlet end of the propulsion module is connected to the outlet, and the suction end of the propulsion module is connected to the return water inlet and the pool tail outlet respectively. The pool tail outlet is connected to the suction end of the propulsion module to form a pool tail bypass return path. The lower functional water area is connected to the return water inlet to form a lower return path. When the partition plate moves vertically, it is used to change the relative flow cross-section between the upper training water area and the lower functional water area, as well as the flow distribution relationship between the pool tail bypass return path and the lower return path to the pool tail water body, thereby adjusting the tail discharge capacity and training load of the main training flow.
[0007] Preferably, the adjustment mechanism includes a horizontal guide rail and at least two sets of parallel transmission arms. The lower end of the parallel transmission arms is hinged to the pool bottom fixed seat, and the upper end is hinged to the horizontal guide rail. The bottom surface of the partition plate is fixedly installed with a guide rail that is slidably connected to the horizontal guide rail, so that the partition plate can be vertically translated during the adjustment process.
[0008] The adjustment mechanism also includes a hydraulic cylinder, the two ends of which are rotatably connected to the bottom of the pool and the horizontal guide rail, respectively, for driving the parallel transmission arm to flip.
[0009] Preferably, when the partition plate moves upward, the effective flow cross-section of the upper training water area decreases, and the proportion of the main return flow task undertaken by the pool tail bypass return path increases, so that the average flow velocity of the upper training water area tends to increase; when the partition plate moves downward, the effective flow cross-section of the upper training water area increases, and the pool tail bypass return path and the lower return path jointly undertake the return flow task, so that the average flow velocity of the upper training water area tends to decrease and the training load is reduced.
[0010] Preferably, the throttling window assembly includes a matrix of orifices disposed on the partition plate and a baffle slidably mounted on the lower side of the partition plate. The baffle is fixedly connected to the horizontal guide rail. When the horizontal guide rail slides relative to the partition plate, the baffle blocks or opens the matrix of orifices to adjust the opening degree of the throttling window assembly.
[0011] Preferably, when the partition plate moves downward, the opening of the throttling window assembly increases to enhance the connectivity between the upper training water area and the lower functional water area, allowing the tailwater to enter the lower return path through the throttling window assembly, thereby improving the tail discharge capacity of the main training stream.
[0012] Preferably, the upper surface of the partition plate is provided with a front detection area and a rear detection area, and one or more millimeter-wave radar sensors are provided in each of the front detection area and the rear detection area to detect the swimmer's front and rear position relative to a predetermined training position interval.
[0013] This invention also proposes a control method for a swimming training device with adaptive flow rate adjustment function, comprising: Obtain the swimmer's forward and backward position relative to a predetermined training position range; Based on the previous and subsequent position states, determine whether the current training load deviates from the preset training load range; When a swimmer is detected to have moved forward relative to the predetermined training position range, the control partition is moved up to reduce the effective flow cross-section of the upper training water area and increase the proportion of the main return flow task undertaken by the bypass return path at the end of the pool, thereby increasing the training load. When a swimmer is detected to have moved backward relative to the predetermined training position range, the control partition moves downward to increase the effective flow cross-section of the upper training water area and to allow the pool tail bypass return path and the lower return path to share the return task, thereby reducing the training load.
[0014] The front and rear position states are obtained by millimeter-wave radar sensors located in the front and rear detection areas of the partition plate.
[0015] The present invention has the following beneficial effects: 1. This invention divides the pool into an upper training water area and a lower functional water area by setting up an adjustable partition plate inside the pool. Combined with the bypass return path at the end of the pool and the return path in the lower layer, a double return structure is formed. This allows the tail discharge capacity of the main training flow to be adjusted according to the position of the partition plate, thereby improving the problems of water stagnation, deceleration and return disturbance at the end of the pool, improving the stability of the main training flow, and solving the problems in the prior art where the training water flow path to the end of the pool is short, the tail discharge is not timely, and stagnation and return disturbance are easy to form when the pool length is short.
[0016] 2. This invention adjusts the relative flow cross-section between the upper training water area and the lower functional water area by changing the height of the partition plate. Under the condition that the output of the propulsion module remains unchanged or changes in a controlled manner, it achieves the adjustment of the average flow velocity trend of the upper training water area. Specifically, when the partition plate moves upward, the effective flow cross-section of the upper training water area decreases, corresponding to a decrease in water volume. The flow rate and energy output by the propulsion module are more conducive to acting on a smaller area of the upper training water area, thus making it more conducive to forming a higher-velocity training mainstream and increasing the average flow velocity of the upper training water area. When the partition plate moves downward, the effective flow cross-section of the upper training water area increases, corresponding to an increase in water volume. The average flow velocity of the upper training water area shows a decreasing trend, thereby achieving adaptive adjustment of the training load and solving the problem of fixed boundary conditions of the training mainstream flow field and limited adjustment of the average flow velocity of the training water area in the prior art.
[0017] 3. This invention enhances or weakens the connectivity between the upper training water area and the lower functional water area by setting a throttling window component on the partition plate and making the opening of the throttling window component change with the adjustment of the partition plate. This allows the tailwater to enter the lower functional water area more rationally according to the working conditions. The lower functional water area can serve as a buffer transfer space for the tailwater and share the return flow task with the tailwater bypass return path. This improves the tailwater discharge capacity of the main training flow and the dual return path distribution and adjustment capacity, solving the problem of fixed return path distribution relationship and difficulty in rationally diverting tailwater according to working conditions in the prior art.
[0018] 4. This invention sets up a front detection area and a rear detection area on the partition plate and uses a millimeter-wave radar sensor to detect the forward and backward positional offset of the swimmer relative to the predetermined training position range. This enables the control system to control the partition plate to move up or down according to the swimmer's forward or backward movement, thereby adjusting the average flow rate trend of the upper training water area. This allows for training load adjustment without solely relying on the propulsion module's speed regulation, improving the device's intelligence level and adaptability to different training stages.

[0029] Example 1
[0030] Reference Figures 1-7 A swimming training device with adaptive flow rate adjustment function includes a pool body 100, a partition plate 200, an adjustment mechanism, a propulsion module 500, and a throttling window assembly.
[0031] like Figure 1 As shown, the pool body 100 is used to contain circulating water and form a swimming training space. A water outlet 101 is provided on the upper side of the inner wall at the front end of the pool body 100, a water return outlet 102 is provided on the lower side of the inner wall at the front end, and a pool tail drain outlet 103 is provided on the upper side of the inner wall at the rear end of the pool body 100.
[0032] like Figure 4As shown, the propulsion module 500 is disposed at the end of the pool body 100. The propulsion module 500 may be a water pump, a propeller, a jet assembly, or a combination thereof. In this embodiment, the propulsion module 500 preferably includes a water pump and inlet and outlet water pipes connected to the water pump. The outlet end of the propulsion module 500 is connected to the outlet 101 for outputting the main training stream into the pool body 100; the suction end of the propulsion module 500 is connected to the return water port 102 and the pool tail drain port 103, respectively.
[0033] A partition 200 is installed inside the pool body 100 to divide the pool body 100 into an upper training area and a lower functional area. Swimmers mainly train against the current in the upper training area, while the lower functional area mainly serves functions such as backflow, buffering, and transferring water at the end of the pool.
[0034] A throttling window assembly is provided at one end of the partition plate 200 near the end drain outlet 103 of the pool. The upper training water area and the lower functional water area are selectively connected through the throttling window assembly. An adjustment mechanism is driven by the partition plate 200 to drive the partition plate 200 to move vertically and to drive the throttling window assembly to open, close, or adjust its opening. Thus, the end drain outlet 103 of the pool is connected to the suction end of the propulsion module 500, forming a bypass return path at the end of the pool; the lower functional water area is connected to the return water inlet 102, forming a lower return path.
[0035] In this embodiment, when the partition plate 200 moves vertically, it not only changes the relative flow cross-section between the upper training water area and the lower functional water area, but also changes the flow distribution relationship between the pool tail bypass return path and the lower return path on the pool tail water body, thereby adjusting the tail discharge capacity and training load of the main training flow.
[0036] By setting up a partition plate 200, the pool body 100 is divided into an upper training water area and a lower functional water area. Combined with the bypass return path at the pool tail and the lower return path, a dual return structure is formed, which allows the formation process of the main training flow, the discharge process at the pool tail, and the distribution process of the return path to coordinate with each other. As a result, the problems of untimely discharge of training water after it reaches the pool tail, which easily leads to stagnation, deceleration, and return disturbance under short pool conditions can be improved.
[0037] Example 2
[0038] Based on Example 1, in order to realize the vertical movement of the partition plate 200, this example further describes the specific structure of the adjustment mechanism.
[0039] like Figure 3 As shown, the adjustment mechanism includes a horizontal guide rail 301, at least two sets of parallel transmission arms 302, a guide rail 303, and a hydraulic cylinder 304.
[0040] like Figure 5As shown, the lower end of the parallel transmission arm 302 is hinged to the bottom fixed seat of the pool body 100, and the upper end is hinged to the horizontal guide rail 301. A guide rail 303, which is slidably connected to the horizontal guide rail 301, is fixedly installed on the bottom surface of the partition plate 200. Both ends of the hydraulic cylinder 304 are rotatably connected to the pool bottom and the horizontal guide rail 301, respectively. When the hydraulic cylinder 304 extends or retracts, it drives the parallel transmission arm 302 to rotate, thereby causing the horizontal guide rail 301 to move along the X and Y axes. Because the partition plate 200 is limited by the inner wall of the pool body 100 and cannot move along the X axis, relative sliding occurs between the guide rail 303 and the horizontal guide rail 301, thereby causing the partition plate 200 to move vertically along the Y axis.
[0041] In this embodiment, the parallel transmission arms 302 are preferably configured as at least two sets that are symmetrical from left to right, so as to improve the stability and uniformity of force during the up-and-down adjustment of the partition plate 200 and avoid significant tilting of the partition plate 200 during the lifting process.
[0042] Through the above structure, the partition plate 200 can maintain a relatively stable horizontal state during the up-down adjustment process, thereby controlling the relative spatial relationship between the upper training water area and the lower functional water area, and also providing a structural basis for the linkage adjustment of the opening of the throttling window component.
[0043] In other embodiments, the hydraulic cylinder 304 may be replaced by a pneumatic cylinder, an electric push rod, or other drive assembly capable of vertically adjusting the partition plate 200; the parallel transmission arm 302 may also be configured as two, three, or more sets depending on the size of the device.
[0044] Example 3
[0045] Based on Example 1 or Example 2, in order to adjust the degree of connectivity between the upper training water area and the lower functional water area, this example further describes the specific structure of the throttling window component.
[0046] like Figure 3 As shown, the throttling window assembly is located at one end of the partition plate 200 near the pool tail drain outlet 103. The throttling window assembly includes a matrix of orifices 401 disposed on the partition plate 200 and a baffle 402 slidably mounted on the lower side of the partition plate 200.
[0047] The matrix-type orifices 401 are preferably arranged along the width and / or length direction of the partition plate 200 to form multiple orifices, so as to achieve different degrees of communication between upper and lower layers under different opening conditions. The baffle 402 is disposed on the lower side of the matrix-type orifices 401 and is fixedly connected to the horizontal guide rail 301.
[0048] like Figure 7As shown, when the horizontal guide rail 301 slides relative to the partition plate 200, the baffle 402 moves along the X-axis in the positive or negative direction, blocking or opening the matrix-type orifice 401, thereby changing the opening degree of the throttling window assembly. Thus, when the partition plate 200 moves up and down, it not only changes the relative flow cross-section between the upper training water area and the lower functional water area, but also causes the opening degree of the throttling window assembly to change.
[0049] like Figure 5 As shown, when the throttling window component opening is small, the connectivity between the upper training water area and the lower functional water area is weakened; for example... Figure 6 As shown, when the throttling window component has a larger opening, the connectivity between the upper training water area and the lower functional water area is enhanced. In this way, the degree of fluid exchange between the upper and lower layers can be adjusted according to the position change of the separator 200.
[0050] In this embodiment, the main function of the throttling window component is to control the ease with which water in the upper training water area enters the lower functional water area in the tail area of the pool, so that the water at the tail of the pool can enter the lower return path more rationally through the throttling window component according to the working conditions, thereby improving the tail discharge capacity of the main training stream.
[0051] Example 4
[0052] Based on Examples 1 to 3, this example further illustrates the collaborative working process of the upper training water area, the lower functional water area, the throttling window component, and the dual return path when the partition plate 200 is in different positions.
[0053] In this embodiment, the partition plate 200 can move vertically under the drive of the adjustment mechanism, thereby changing the relative flow cross section between the upper training water area and the lower functional water area, and changing the opening of the throttling window component, thereby adjusting the return flow distribution relationship of the pool tail bypass return path and the lower return path to the pool tail water body.
[0054] (1) Divider plate moving upwards like Figure 5 As shown, when the partition plate 200 moves upward, the effective flow section S1 of the upper training water area decreases, the relative space of the lower functional water area increases, and the opening of the throttling window component decreases, thus weakening the connectivity between the upper training water area and the lower functional water area.
[0055] Under this operating condition, the effective flow cross-section of the upper training water area decreases, and consequently, the corresponding water volume also decreases. With the output flow rate of the propulsion module 500 remaining constant or subject to controlled variation, based on the relationship between flow rate, flow cross-section, and flow velocity, the upper training water area is more conducive to forming a higher average flow velocity. In other words, the flow rate and energy output by the propulsion module 500 can act on a smaller area of the upper training water area, thus being more conducive to forming a higher-velocity training mainstream.
[0056] Meanwhile, since the upper training water area has a smaller water volume, the establishment and adjustment of the training mainstream is more easily concentrated in a smaller range, which is more conducive to the rapid formation of the flow field state corresponding to the current working conditions.
[0057] Furthermore, due to the smaller opening of the throttling window component, the likelihood of water from the lower functional water area entering the upper training water area through the throttling window component is reduced, thereby minimizing the interference of lower-level return water on the upper training mainstream. Simultaneously, water at the pool tail more easily enters the pool tail bypass return path through the pool tail drain outlet 103, and then is output through the propulsion module 500 to form the main training circulation. Therefore, when the partition plate 200 moves upward, the pool tail bypass return path undertakes a higher proportion of return tasks, meeting the needs of the main training circulation under high training load conditions.
[0058] Therefore, under the condition of the separator 200 moving upward, on the one hand, the average flow velocity trend of the upper training water area can be improved by reducing the effective flow cross-section of the upper training water area; on the other hand, the possibility of the lower water flowing back to the upper layer through the throttling window component can be reduced, thereby reducing the interference of the lower backflow water on the upper training mainstream. This condition is suitable for scenarios such as intensive training, sprint training, or scenarios requiring a higher training mainstream level.
[0059] (2) Divider plate moving down condition like Figure 6 As shown, when the partition plate 200 moves downward, the effective flow section S2 of the upper training water area increases, the relative space of the lower functional water area decreases, and the opening of the throttling window component increases, thus enhancing the connectivity between the upper training water area and the lower functional water area.
[0060] Under this condition, the effective flow cross-section of the upper training water area increases, and the corresponding water volume also increases. With the output flow rate of the propulsion module 500 remaining constant or under controlled variation, the average flow velocity of the upper training water area shows a decreasing trend, thus helping to reduce the training load.
[0061] Meanwhile, due to the increased water volume in the upper training water area, the scope of water involved in establishing and adjusting the main training current is larger, and its flow field response tends to be gentler. In other words, the water in the upper training water area cannot easily complete the state change in a short period of time, so it is more necessary to use tail-end discharge and return path adjustment to coordinate and achieve changes in training load.
[0062] With the increased opening of the throttling window component, the water at the tail of the pool can more easily enter the lower functional water area through the throttling window component. At this time, the lower functional water area, in addition to serving as part of the lower return path, can also act as a buffer transfer space for the water at the tail of the pool. That is to say, the water at the tail of the pool does not have to rely entirely on the direct return from the tail outlet 103, but can partially enter the lower functional water area first, and then return to the propulsion module 500 through the lower return outlet 102 at the front end, so that the tail bypass return path and the lower return path jointly undertake the return task.
[0063] Therefore, when the separator 200 moves downward, it can, on the one hand, reduce the average flow velocity trend of the upper training water area by increasing the effective flow cross-section, and on the other hand, enhance the connection between the upper and lower layers by increasing the opening of the throttling window component. This makes it easier for the water at the tail of the pool to transfer to the lower functional water area, and utilizes the lower functional water area to buffer and return the water at the tail of the pool. This improves the tail discharge capacity of the main training stream and reduces the impact of pool tail stagnation, deceleration, accumulation, and return disturbance on the upper training stream. This operating condition is suitable for warm-up training, recovery training, protection mode, or load reduction adjustment scenarios when swimmers' physical strength declines.
[0064] In this embodiment, the upward and downward movement of the partition plate 200 not only changes the relative flow cross-section between the upper training water area and the lower functional water area, but also alters the opening of the throttling window component and the return flow distribution relationship between the pool tail bypass return path and the lower return path. Specifically, when the partition plate 200 moves upward, the corresponding water volume in the upper training water area decreases, which is more conducive to increasing the average flow velocity in the upper training water area and reducing the interference of the lower return water on the upper training mainstream. When the partition plate 200 moves downward, the corresponding water volume in the upper training water area increases, which is more conducive to reducing the average flow velocity in the upper training water area and allowing the lower functional water area to act as a buffer transfer space for the pool tail water body, sharing the return flow task with the pool tail bypass return path. Through the above adjustment methods, the combined adjustment of training load and tail discharge capacity can be achieved without solely relying on the speed regulation of the propulsion module 500.
[0065] Example 5
[0066] Based on Examples 1 to 4, this example further illustrates the control method of the above-mentioned swimming training device.
[0067] First, the swimmer's forward and backward position relative to a predetermined training position range is acquired. Preferably, a forward detection area 201 and a backward detection area 202 are provided on the upper surface of the partition plate 200, and one or more millimeter-wave radar sensors are provided in each of the forward and backward detection areas 201 and 202 to detect the swimmer's forward and backward position shift relative to the predetermined training position range.
[0068] Then, based on the previous and next position states, it is determined whether the current training load deviates from the preset training load range.
[0069] When a swimmer is detected to have moved forward relative to the predetermined training position range, the control partition 200 is moved upward to reduce the effective flow cross-section of the upper training water area and to make the pool tail bypass return path bear a higher proportion of the return flow task, thereby increasing the average flow velocity trend of the upper training water area and increasing the training load.
[0070] When a swimmer is detected to have moved backward relative to the predetermined training position range, the control partition 200 is moved downward to increase the effective flow cross-section of the upper training water area and to make the pool tail bypass return path and the lower return path share the return task, thereby reducing the average flow velocity trend of the upper training water area and reducing the training load.
[0071] The predetermined training position range refers to the preset position range that swimmers should maintain during training. This predetermined training position range is located within the upper training water area and can be preset according to the training mode, training load, or user conditions. In some embodiments, the predetermined training position range corresponds to a predetermined spatial range between the front detection area 201 and the rear detection area 202 on the upper surface of the partition plate 200.
[0072] In this embodiment, the separator 200 is the main adjustment means, while the output of the propulsion module 500 remains constant or changes in a controlled manner. That is to say, the present invention does not simply rely on the speed adjustment of the propulsion module 500, but rather adjusts the position of the separator 200 and the opening of the throttling window component to change the relationship between the upper training water area, the lower functional water area, and the dual return path, thereby achieving training load adjustment.
[0073] In other embodiments, the propulsion module 500 can also serve as an auxiliary adjustment means. For example, when the partition plate 200 has been adjusted to the preset upper or lower limit position but the training load has not yet reached the preset training load range, the output of the propulsion module 500 can be further adjusted to expand the training load adjustment range of the device.
[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The lower functional water area is connected to the return water inlet (102) to form a lower return path. When the partition plate (200) moves vertically, it is used to change the relative flow cross section between the upper training water area and the lower functional water area, as well as the flow distribution relationship between the pool tail bypass return path and the lower return path to the pool tail water body, thereby adjusting the tail discharge capacity and training load of the main training flow.
2. The swimming training device with adaptive flow rate adjustment function according to claim 1, characterized in that: The adjustment mechanism includes a horizontal guide rail (301) and at least two sets of parallel transmission arms (302). The lower end of the parallel transmission arm (302) is hinged to the bottom fixed seat of the pool, and the upper end is hinged to the horizontal guide rail (301). The bottom surface of the partition plate (200) is fixedly installed with a guide rail (303) that is slidably connected to the horizontal guide rail (301) so that the partition plate (200) can be vertically translated during the adjustment process.
3. A swimming training device with adaptive flow rate adjustment function according to claim 2, characterized in that: The adjustment mechanism also includes a hydraulic cylinder (304), the two ends of which are rotatably connected to the bottom of the pool and the horizontal guide rail (301) respectively, for driving the parallel transmission arm (302) to flip.
4. A swimming training device with adaptive flow rate adjustment function according to claim 1, characterized in that: When the partition plate (200) moves upward, the effective flow cross section of the upper training water area decreases, and the proportion of the main return flow task undertaken by the pool tail bypass return path increases, so that the average flow velocity of the upper training water area tends to increase; when the partition plate (200) moves downward, the effective flow cross section of the upper training water area increases, and the pool tail bypass return path and the lower return path jointly undertake the return flow task, so that the average flow velocity of the upper training water area tends to decrease and the training load is reduced.
5. A swimming training device with adaptive flow rate adjustment function according to claim 1, characterized in that: The throttling window assembly includes a matrix-type orifice (401) disposed on the partition plate (200) and a baffle (402) slidably mounted on the lower side of the partition plate (200). The baffle (402) is fixedly connected to the horizontal guide rail (301). When the horizontal guide rail (301) slides relative to the partition plate (200), the baffle (402) blocks or opens the matrix-type orifice (401) to adjust the opening degree of the throttling window assembly.
6. A swimming training device with adaptive flow rate adjustment function according to claim 5, characterized in that: When the partition plate (200) moves down, the opening of the throttling window assembly increases to enhance the connectivity between the upper training water area and the lower functional water area, allowing the tail water to enter the lower return path through the throttling window assembly, thereby improving the tail discharge capacity of the main training stream.
