[0054] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0055] like Figures 1-11 As shown, the vortex type ocean current simulation generating device 100 for a diving pool according to an embodiment of the present invention includes a vortex generating tube 1, a water inlet system 2, a vortex generating component 3, an vortex detection component 4 and a controller 5.

[0056] Diving pool 200 is preferably built in the indoor diving pool of large commercial center, is used for diving recreational sports, certainly also can be used for diver's training and training.It is understandable that diving pool 200 also can be built in other suitable places, for example is built in outdoor outdoor diving pool.

[0057] The vortex generating tube 1 is along its axial direction ( Figure 1 in the up-down direction) has a first end ( Figure 1 The upper end of the middle) and the second end ( Figure 1 The vortex generating cylinder 1 has a vortex outlet 11 for discharging the vortex at the first end, and the vortex generating cylinder 1 has a water inlet 12 adjacent to the second end.

[0058] exist Figure 1 In the illustrated embodiment, the vortex generating tube 1 extends axially in the vertical direction, with the upper end of the vortex generating tube 1 extending into the submersible pool 200, i.e., the vortex outlet 11 is located within the submersible pool 200. It will be appreciated that the vortex generating tube 1 can extend axially in the horizontal direction or at an angle, and the vortex generating tube 1 can be appropriately positioned based on the desired ocean current conditions within the submersible pool 200. Alternatively, a submersible pool 200 can be provided with multiple vortex generating tubes 1, i.e., multiple vortex ocean current simulation generating devices 100, to generate the desired vortex ocean current within the submersible pool 200.

[0059] Water inlet system 2 is connected to water inlet 12 and is used to supply water into vortex generating cylinder 1. Vortex generating assembly 3 is disposed within vortex generating cylinder 1 and is used to generate vortices (or swirling currents) within vortex generating cylinder 1. The vortex generated by vortex generating assembly 3 within vortex generating cylinder 1 is discharged through vortex outlet 11 into submersible pool 200, thereby generating vortex currents within submersible pool 200 that simulate natural ocean vortex currents.

[0060] The vortex generating assembly 3 includes a first impeller 31 and a first impeller rotation driving motor 32. The first impeller rotation driving motor 32 is connected to the first impeller 31 and is used to drive the first impeller 31 to rotate and generate vortex in the vortex generating cylinder 1. Figure 1-11 As shown, the first impeller rotation drive motor 32 is a shaft motor. Preferably, the rotation axis of the first impeller 31 is consistent with the axial direction of the vortex generating cylinder 1. Figure 1 Optionally, the rotation axis of the first impeller 31 may be at a predetermined angle to the vertical direction. The angle cannot be too large, otherwise the vortex will easily collide with the inner wall of the vortex generating cylinder 1, increasing energy consumption. For example, the angle is less than 10 degrees.

[0061] The eddy current detection assembly 4 is disposed within the vortex generating cylinder 1, downstream of the first impeller 31, and is used to detect at least one vortex parameter within the vortex generating cylinder 1: the vortex velocity and the vortex pressure. In other words, along the direction of water flow within the vortex generating cylinder 1, the vortex detection assembly 4 is located downstream of the first impeller 31, i.e., the vortex detection assembly 4 is closer to the vortex outlet 11 than the first impeller 31. Preferably, the vortex detection assembly 4 is adjacent to the vortex outlet 11.

[0062] The controller 5 is connected to the first impeller rotation drive motor 32 and the eddy current detection assembly 4. The controller 5 controls the first impeller rotation drive motor 32 to drive the first impeller 31 to rotate based on at least one eddy current parameter, thereby generating the desired simulated eddy current. It is understood that the controller 5 may be pre-set with a control program. The controller 5 may periodically control the first impeller 31 according to the pre-set control program, for example, controlling the speed of the first impeller 31, intermittently controlling the rotation and stopping of the first impeller 31, etc., and simultaneously adjusts the control of the first impeller 31 in real time based on the detected eddy current parameter to comply with the pre-set program and meet the design requirements for the eddy current.

[0063] The vortex ocean current simulation generating device for a diving pool in an embodiment of the present invention utilizes the rotation of a first impeller to generate a vortex in a vortex generating cylinder and discharges it into the diving pool through a vortex outlet, thereby simulating a vortex ocean current in the diving pool. The simulated vortex ocean current simulates the natural vortex ocean current of the ocean realistically and the simulation is controllable, so that the vortex intensity level can be controlled according to different needs, such as beginner practice, leisure sports, professional diver diving training, etc., thereby improving safety and diving training effects, and enhancing the experience of diving leisure sports.

[0064] In some embodiments, the vortex generating assembly 3 also includes a first blade angle adjustment motor 33, which is connected to the first blade 312 of the first impeller 31 to drive the first blade 312 to swing around its own axis and change the deflection angle of the first blade 312 relative to its rotation plane. The controller 5 is also connected to the first blade angle adjustment motor 33 to control the first blade angle adjustment motor 33 to drive the first blade 312 to swing according to at least one vortex parameter. The first blade angle adjustment motor 33 and the first impeller rotation drive motor 32 can rotate independently of each other. By adjusting the rotation speed of the first impeller 31 and the deflection angle of the first blade 312, the controllability of the vortex can be further improved and the intensity level range of the simulated vortex can be expanded.

[0065] In some embodiments, the vortex generating assembly 3 further includes a second impeller 35 and a second impeller rotation drive motor 36, the second impeller rotation drive motor 36 being connected to the second impeller 35, the second impeller rotation drive motor 36 driving the second impeller 35 to rotate to generate a vortex in the vortex generating cylinder 1, the first impeller 31 and the second impeller 35 being connected to each other by a coupling 39 and being able to rotate independently of each other, in other words, the second impeller 35 and the first impeller 31 can be said to be connected in series. The controller 5 is also connected to the second impeller rotation drive motor 36 to control the second impeller rotation drive motor 36 to drive the second impeller 35 to rotate according to at least one vortex parameter. Preferably, the first blade 312 of the first impeller 31 is larger than the second blade 352 of the second impeller 35 and the first impeller 31 is located downstream of the second impeller 35.

[0066] In this embodiment, by providing a second impeller, the controllability of the vortex can be further improved and the range of intensity levels of the simulated vortex can be expanded.

[0067] In some embodiments, the vortex generating assembly 3 further includes a second blade angle adjustment motor 37, which is connected to the second blade 352 of the second impeller 35 to drive the second blade 352 to swing about its own axis, thereby changing the deflection angle of the second blade 352 relative to its rotation plane. The controller 5 is also connected to the second blade angle adjustment motor 37 to control the second blade angle adjustment motor 37 to drive the second blade 352 to swing according to at least one vortex parameter.

[0068] In this embodiment, by adjusting the deflection angle of the first blade 312 , the controllability of the vortex can be further improved, and the range of intensity levels of the simulated vortex can be expanded.

[0069] Reference below Figure 1-11 The eddy current simulation generating device 100 according to a specific embodiment of the present invention is described.

[0070] like Figures 1-11As shown, eddy current simulation device 100 is used to generate artificial eddy currents within a diving pool 200 that simulates natural ocean eddy currents. Diving pool 200 is an indoor diving pool used for recreational diving, enthusiast diving training, and professional diver training. Eddy current simulation device 100 includes a eddy current generating tube 1, a water inlet system 2, a eddy current generating assembly 3, an eddy current detection assembly 4, and a controller 5.

[0071] like Figure 2 and Figure 3 As shown, the vortex generating cylinder 1 is cylindrical, and the upper end of the vortex generating cylinder 1 is open to form a vortex outlet 11. Preferably, the upper end of the vortex generating cylinder 1 is trumpet-shaped, and the lower end of the vortex generating cylinder 1 is closed. The vortex generating cylinder 1 is provided with a water inlet 12 connected to the water inlet system 2 near the lower end. The upper end of the vortex generating cylinder 1 extends into the diving pool 200. Figure 1 In the example shown, the vortex generating tube 1 extends into the diving pool from the bottom of the diving pool 200. Optionally, the vortex generating tube 1 can be extended from the side of the diving pool 200, or multiple vortex generating tubes 1 can be provided (that is, the diving pool is provided with multiple vortex ocean current simulation generating devices), which extend into the diving pool from different positions of the diving pool 200 to obtain the vortex ocean current required by the design in the diving pool 200.

[0072] like Figure 4 As shown, the water inlet system 2 includes a water pump 21, a control valve 22, and a flow meter 23 and a pressure gauge 24 arranged between the outlet of the water pump 21 and the water inlet 12. The inlet of the water pump 21 is connected to a water source. Preferably, the water inlet system 2 is provided with a water tank 25, and the water pump 21 is arranged in the water tank 25. Water first enters the water tank 25, and the water level in the water tank 25 is maintained within a certain height range. When the water pump 21 pumps water, it is not affected by fluctuations in the amount of incoming water, thereby preventing the water pump 21 from sucking water empty. The outlet of the water pump 21 is connected to the water inlet 12 of the vortex generating cylinder 1. The flow meter 23 is used to detect the water supply flow rate of the water pump 21 to the vortex generating cylinder 1, and the pressure gauge 24 is used to detect the water supply pressure of the water pump 21 to the vortex generating cylinder 1. The control valve 22 can be a solenoid valve, which is arranged between the outlet of the water pump and the water inlet 12. The control valve 22 is connected to the controller 5. The controller 5 can control the on-off of the water inlet pipeline and the size of the water flow by controlling the control valve 22.

[0073] like Figure 5-Figure 7 As shown, the vortex generating assembly 3 is arranged in the vortex generating cylinder 1, and is used to generate vortex in the vortex generating cylinder 1. Figure 2 As shown, a bracket 6 is provided in the vortex generating tube 1, and the vortex generating assembly 3 is mounted on the bracket 6. The vortex generating assembly 3 includes a first impeller 31, a first impeller rotation drive motor 32, a first blade angle adjustment motor 33, a second impeller 35, a second impeller rotation drive motor 36, and a second blade angle adjustment motor 37.

[0074] The first impeller 31 includes a first impeller shell 311, a plurality of first blades 312, and a first moving body 34. The first blades 312 are connected to the first impeller shell 311 and can rotate relative to the first impeller shell 311 around their own axis X. The root of the first blade 312 is located in the first impeller shell 311 and is provided with a first blade actuator 3121. The first moving body 34 is provided in the first impeller shell 311. The first moving body 34 rotates relative to the first impeller shell 311 along the axial direction of the first impeller (such as Figure 5 and Figure 6 When the first moving body 34 moves up and down, the first blade actuator 3121 can be actuated to swing the first blade 312 around its own axis X, thereby changing the first blade 312 relative to its rotation plane ( Figure 7 The first moving body 34 is limited by the inner wall of the first impeller shell 311, so that the first moving body 34 can translate along the axial direction of the first impeller but is restricted from rotating relative to the first impeller shell 311.

[0075] The second impeller 35 includes a second impeller shell 351, a plurality of second blades 352, and a second moving body 38. The second blades 352 are connected to the second impeller shell 351 and can rotate around their own axes relative to the second impeller shell 351. The root of the second blade 352 is located in the second impeller shell 351 and is provided with a second blade actuator. The second moving body 38 is arranged in the second impeller shell 351 and is relative to the second impeller shell 351 along the axial direction of the second impeller (such as Figure 5 and Figure 6 The second movable body 38 is movable (in the vertical direction) within the second impeller housing 351. When the second movable body 38 moves, it actuates the second blade actuator to cause the second blade 352 to swing about its own axis, thereby changing the deflection angle of the second blade 352 relative to its rotation plane. The second movable body 38 is restrained by the inner wall of the second impeller housing 351, allowing translation within the second impeller housing 351 but being restricted from rotation relative to the second impeller housing 351.

[0076] The rotation axis of the first impeller 31 and the second impeller 35 coincides with the axial direction of the vortex generating cylinder 1. Figure 6 The first impeller 31 and the second impeller 35 are connected to each other via a coupling 39 and can rotate independently of each other. In other words, the first impeller 31 and the second impeller 35 can rotate simultaneously, at the same or different speeds. Alternatively, the first impeller 31 and the second impeller 35 can rotate at different speeds, for example, one rotating while the other does not, thereby obtaining different vortices and improving the simulation of natural ocean currents.

[0077] Specifically, the first impeller 31 and the second impeller 35 are arranged along the axial direction of the vortex generating cylinder 1 ( Figure 5 and Figure 6 The first impeller 31 and the second impeller 35 are arranged at intervals (in the up and down directions), and the second impeller 35 is located upstream of the first impeller 31. A first connecting shaft 3111 is provided on the first impeller shell 311 of the first impeller 31, and a second connecting shaft 3511 is provided on the second impeller shell 351 of the second impeller 35. The first connecting shaft 3111 is rotatably connected to one end of the coupling 39, and the second connecting shaft 3511 is rotatably connected to the other end of the coupling 39. The coupling 39 can connect the first impeller 31 and the second impeller 35 along the axial direction of the vortex generating tube 1. Therefore, when the first impeller 31 and the second impeller 35 rotate, the stability of the first impeller 31, the second impeller 35 and the transmission components connected to the two can be improved, and the failure rate can be reduced. Preferably, the first blade 312 of the first impeller 31 is larger than the second blade 352 of the second impeller 35 and the first impeller 31 is located downstream of the second impeller 35, so as to balance the load of the motor driving the first impeller 31 and the second impeller 35, and avoid excessive load on the second impeller 35 located upstream at the early stage of vortex formation.

[0078] like Figure 6-Figure 9 As shown, the first impeller rotation drive motor 32 and the first blade angle adjustment motor 33 are both shaft-type motors. The first impeller rotation drive motor 32 and the first blade angle adjustment motor 33 are located below the first impeller 31. The first impeller rotation drive motor 32 has a hollow first rotation drive shaft 321. The first rotation drive shaft 321 is connected to the first impeller shell 311 of the first impeller 31 via a hollow first rotation drive connecting shaft 322 to drive the first impeller 31 to rotate. A first fixed disk 323 is provided at the end of the first rotation drive shaft 321 away from the first impeller 31. The first blade angle adjustment motor 33 is fixedly connected to the first fixed disk 323, so that the first impeller rotation drive motor 32 and the first blade angle adjustment motor 33 are stacked along the axial direction of the first impeller rotation drive motor 32, reducing the space occupied by the vortex generating tube 1. The first impeller rotation drive motor 32 and the first blade angle adjustment motor 33 are both located in the center area of ​​the vortex within the vortex generating tube 1, reducing the disturbance to the water flow.

[0079] The first blade angle adjustment motor 33 includes a first blade angle adjustment shaft 331, which is provided with a first external thread 3311. The first movable body 34 is provided with a first internal thread 341. The first external thread 3311 of the first blade angle adjustment shaft 331 passes through the first rotation drive shaft 321 and the first rotation drive connecting shaft 322, and then engages with the first internal thread 341 on the first movable body 34, thereby driving the first movable body 34 to move up and down relative to the first impeller housing 311 to adjust the deflection angle of the first blade.

[0080] When the first impeller rotation drive motor 32 drives the first rotation drive shaft 321 to rotate, the first impeller housing 311, the first blades 312, the first moving body 34, the first blade angle adjustment motor 33, and the first blade angle adjustment shaft 331 all rotate synchronously with the first rotation drive shaft 321. If the deflection angle of the first blade 312 needs to be adjusted while the first impeller 31 is rotating, the first blade angle adjustment motor 33 can be used to drive the first blade angle adjustment shaft 331 to rotate. The rotation of the first rotation drive shaft 321 and the first impeller 31 does not affect the independent operation of the first blade angle adjustment motor 33.

[0081] like Figure 6 、 Figure 7 、 Figure 10 and Figure 11 As shown, the second impeller rotation drive motor 36 and the second blade angle adjustment motor 37 are both shaft-type motors. The second impeller rotation drive motor 36 and the second blade angle adjustment motor 37 are located upstream of the second impeller 35. The second impeller rotation drive motor 36 has a hollow second rotation drive shaft 361, which is connected to the second impeller shell 311 of the second impeller 35 via a hollow second rotation drive connecting shaft 362 to drive the second impeller 35 to rotate. A second fixed disk 363 is provided at the end of the second rotation drive shaft 361 away from the second impeller 35. The second blade angle adjustment motor 37 is fixedly connected to the second fixed disk 363, so that the second impeller rotation drive motor 36 and the second blade angle adjustment motor 37 are stacked along the axial direction of the second impeller rotation drive motor 36, reducing the space occupied by the vortex generating tube 1. The second impeller rotation drive motor 36 and the second blade angle adjustment motor 37 are both located in the central area of ​​the vortex in the vortex generating tube 1, thereby reducing the disturbance to the water flow.

[0082] The second blade angle adjustment motor 37 has a second blade angle adjustment shaft 371, a second external thread 3711 is set on the second blade angle adjustment shaft 371, and a second internal thread 381 is set on the second movable body 38. The second external thread 3711 of the second blade angle adjustment shaft 371 passes through the second rotation drive shaft 361 and the second rotation drive connecting shaft 362 and is threadedly engaged with the second internal thread 381 on the second movable body 38 to drive the second movable body 38 to move up and down along the second impeller 35 relative to the second impeller shell 311 to adjust the deflection angle of the second blade.

[0083] When the second impeller rotation drive motor 36 drives the second rotation drive shaft 361 to rotate, the second impeller housing 311, the second blades 312, the second movable body 38, the second blade angle adjustment motor 37, and the second blade angle adjustment shaft 371 all rotate synchronously with the second rotation drive shaft 361. If the deflection angle of the second blades 312 needs to be adjusted while the second impeller 35 is rotating, the second blade angle adjustment motor 37 can be used to drive the second blade angle adjustment shaft 371 to rotate. The rotation of the second rotation drive shaft 361 and the second impeller 35 does not affect the independent operation of the second blade angle adjustment motor 37.

[0084] The vortex generating assembly in this embodiment has a high degree of integration and a compact structure, which reduces the space volume occupied in the vortex generating cylinder and reduces the disturbance to the flow of water in the vortex generating cylinder. The first impeller and the second impeller can improve the controllability of the vortex and expand the range of simulated vortex styles and intensity levels.

[0085] like Figure 2 As shown, there are multiple brackets 6 arranged on the inner wall of the vortex generating cylinder 1, wherein the first rotary drive shaft 321 and the second rotary drive shaft 361 are rotatably connected to the corresponding brackets 6 through bearings, the first impeller rotary drive motor 32 and the second impeller rotary drive motor 36 are fixedly connected to the corresponding brackets 6, and the coupling 39 is fixedly connected to the corresponding bracket 6.

[0086] Each bracket 6 includes multiple support rods arranged circumferentially on the inner wall of the vortex generating cylinder 1. This structural form can reduce the obstruction of the water in the vortex generating cylinder 1. For example, the number of support rods in each bracket 6 can be 2 to 4. The support rods can be round rods or flat plates. When the support rods are flat plates, they can be arranged at an angle along the flow direction of the water.

[0087] like Figure 1 As shown, the eddy current detection assembly 4 includes a flow meter 41 and a pressure sensor 42, which are provided on the eddy current generating cylinder 1 and downstream of the first impeller 31. The flow meter 41 is used to detect the flow velocity of the eddy current, and the pressure sensor 42 is used to detect the pressure of the eddy current. Optionally, the number of flow meters 41 and pressure sensors 42 can be one or more. For example, multiple flow meters 41 and multiple pressure sensors 42 are spaced apart along the circumference of the eddy current generating cylinder 1, so that more reliable eddy current parameters can be obtained by collecting multiple data information.

[0088] In addition, if it is necessary to detect the water flow between the first impeller 31 and the second impeller 35 in the vortex generating cylinder 1, a flow meter 41 and a pressure sensor 42 can also be arranged between the second impeller 35 and the first impeller 31.

[0089] The controller 5 is connected to the flow meter 41, the pressure sensor 42, the flow meter 23 and the pressure gauge 24 to obtain the detection values ​​of the flow meter 41, the pressure sensor 42, the flow meter 23 and the pressure gauge 24. The controller 5 is connected to the first impeller rotation drive motor 32, the second impeller rotation drive motor 36, the first blade angle adjustment motor 33, the second blade angle adjustment motor 37, the water pump 21 and the control valve 22 to control the operation of the first impeller rotation drive motor 32, the second impeller rotation drive motor 36, the first blade angle adjustment motor 33, the second blade angle adjustment motor 37, the water pump 21 and the control valve 22 according to the above detection values.

[0090] It is understandable that the controller 5 is capable of regulating the rotation speed of the first impeller 31, the deflection angle of the first blade 312, the rotation speed of the second impeller 35, the deflection angle of the second impeller 352, and the flow rate and pressure of the water pumped into the vortex generating cylinder 1 by the water pump 21. By adjusting the parameters of at least some of the above components, the vortex is controlled, vortices of different styles and intensity levels are obtained, and conversion between different vortices is achieved, thereby improving the controllability of the vortex and expanding the range of intensity levels of the simulated vortex. At the same time, the formation speed of the vortex can be increased by rationally optimizing the control strategy, thereby improving the experience of diving.

[0091] For example, during the startup phase, at the initial stage of vortex formation, the controller 5 controls the rotation of one of the first impeller 31 and the second impeller 35 to form a vortex with a relatively small intensity level in the vortex generating cylinder, and then controls the two impellers to rotate simultaneously, and gradually increases the pumping flow and pressure of the water pump 21, and increases one or more parameters of the first impeller 31, the deflection angle of the first blade 312, the rotation speed of the second impeller 35, and the deflection angle of the second blade 352 until the desired vortex pattern and intensity level are achieved. In this process, the first impeller rotation drive motor 32, the second impeller rotation drive motor 36, the first blade angle adjustment motor 33, the second blade angle adjustment motor 37, and the water pump 21 can operate within a normal load range to avoid overload of the motor.

[0092] For another example, after the vortex in the vortex generating cylinder is maintained at a certain intensity level, when the intensity level of the vortex needs to be increased, the intensity level of the vortex can be increased by increasing the pumping pressure of the water pump, increasing the speed of the first impeller, increasing the speed of the second impeller, or by changing the deflection angle of the first blade or the second blade; accordingly, when the intensity level of the vortex needs to be reduced, the intensity level of the vortex can be reduced by reducing the pumping pressure of the water pump, reducing the speed of the first impeller, reducing the speed of the second impeller, or by changing the deflection angle of the first blade or the second blade. This embodiment has more parameter combinations to achieve the adjustment of the vortex intensity level, and can perform the adjustment of the vortex parameters by selecting a more reasonable strategy to increase the adjustment speed, reduce energy consumption, and improve user satisfaction.

[0093] For another example, when the operating loads of the first impeller, the second impeller and the water pump are increased rapidly at the same time, the vortex intensity level can be quickly increased and the sudden changes in vortex ocean currents in a real environment can be simulated, so that simulated training can be carried out under dangerous conditions where the vortex intensity level suddenly changes, thereby improving the diving training effect and the experience of diving sports.
