[0054] 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 Figure 1-Figure 11 As shown, the vortex type ocean current simulation generating device 100 for a diving pool according to an embodiment of the present invention comprises a vortex generating tube 1, a water inlet system 2, a vortex generating component 3, a vortex detecting 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 can also 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 first end of the vortex generating cylinder 1 has a vortex outlet 11 for discharging the vortex, 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 axial direction of the vortex generating tube 1 extends in the up-down direction, and the upper end of the vortex generating tube 1 extends into the submersible pool 200, that is, the vortex outlet 11 is located in the submersible pool 200. It is understandable that the axial direction of the vortex generating tube 1 can extend in the horizontal direction or extend obliquely, and the vortex generating tube 1 can be appropriately arranged according to the ocean current conditions required to be generated in the submersible pool 200. Optionally, a submersible pool 200 can be provided with multiple vortex generating tubes 1, that is, multiple vortex ocean current simulation generating devices 100 are arranged to generate the required vortex ocean current in the submersible pool 200.

[0059] The water inlet system 2 is connected to the water inlet 12, and is used to supply water to the vortex generating cylinder 1. The vortex generating assembly 3 is arranged in the vortex generating cylinder 1, and is used to generate a vortex (or vortex flow) in the vortex generating cylinder 1. The vortex generated by the vortex generating assembly 3 in the vortex generating cylinder 1 is discharged from the vortex outlet 11 into the submersible pool 200, thereby generating a vortex current in the submersible pool 200 that simulates the vortex current of the natural ocean.

[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 to 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 tube 1. Figure 1 Optionally, the rotation axis of the first impeller 31 may be at a predetermined angle to the vertical direction, and the angle cannot be too large, otherwise the vortex easily collides 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 component 4 is arranged in the eddy current generating cylinder 1 and is located downstream of the first impeller 31, and is used to detect at least one eddy current parameter of the eddy current velocity and the eddy current pressure in the eddy current generating cylinder 1. In other words, along the water flow direction in the eddy current generating cylinder 1, the eddy current detection component 4 is located downstream of the first impeller 31, that is, the eddy current detection component 4 is closer to the eddy current outlet 11 than the first impeller 31. Preferably, the eddy current detection component 4 is adjacent to the eddy current outlet 11.

[0062] The controller 5 is connected to the first impeller rotation drive motor 32 and the eddy current detection component 4. The controller 5 controls the first impeller rotation drive motor 32 to drive the first impeller 31 to rotate according to at least one eddy current parameter, so as to generate the desired simulated eddy current. It is understandable that the controller 5 may be preset with a control program. The controller 5 may periodically control the first impeller 31 according to the preset control program, for example, control the speed change of the first impeller 31, intermittently control the rotation and stop of the first impeller 31, etc., and adjust the control of the first impeller 31 in real time according to the detected eddy current parameters to comply with the preset 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 has a realistic simulation effect on the natural vortex ocean current in the ocean, and the simulation is controllable, so that the vortex intensity level can be controlled according to different needs, such as beginner practice, leisure sports, and professional diver diving training, 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 is connected to the second impeller 35, the second impeller rotation drive motor 36 drives 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 are connected to each other through a coupling 39 and can rotate independently of each other, in other words, the second impeller 35 and the first impeller 31 can be referred to as a series connection. 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 around its own axis to change 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 the intensity level 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 Figure 1-Figure 11As shown, the eddy current simulation generating device 100 is used to generate artificial simulated eddy currents simulating natural eddy currents in a diving pool 200. The diving pool 200 is a diving pool built indoors and is used for diving leisure sports, training of diving enthusiasts and professional training of divers. The eddy current simulation generating device 100 includes a eddy current generating tube 1, a water inlet system 2, an eddy current generating component 3, an eddy current detection component 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 submersible 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 the fluctuation of the incoming water volume, so as to avoid 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 may be a solenoid valve, which is disposed between the outlet of the water pump and the water inlet 12 . The control valve 22 is connected to the controller 5 , and the controller 5 may control the on-off of the water inlet pipeline and the size of the water flow rate 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 arranged in the first impeller shell 311. The first moving body 34 is 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 make the first blade 312 swing 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 limited to rotate 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 When the second moving body 38 moves, it can actuate the second blade actuating portion to make the second blade 352 swing around its own axis to change the deflection angle of the second blade 352 relative to its rotation plane. The second moving body 38 is limited by the inner wall of the second impeller shell 351, so that it can translate in the second impeller shell 351 but is limited to rotate relative to the second impeller shell 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 through a coupling 39 and can rotate independently of each other. In other words, the first impeller 31 and the second impeller 35 can rotate at the same time, and the speeds can be the same or different. Optionally, the first impeller 31 and the second impeller 35 can rotate at different times, for example, one rotates and the other does not rotate, so that different vortices can be obtained, thereby improving the simulation effect of natural ocean currents.

[0077] Specifically, the first impeller 31 and the second impeller 35 are arranged along the axial direction ( Figure 5 and Figure 6 The first impeller 31 and the second impeller 35 are arranged at intervals (in the up and down direction), 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 initial 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 motors. The first impeller rotation drive motor 32 and the first blade angle adjustment motor 33 are located below the first impeller 31, and the first impeller rotation drive motor 32 has a hollow first rotation drive shaft 321, and the first rotation drive shaft 321 is connected to the first impeller shell 311 of the first impeller 31 through a hollow first rotation drive connecting shaft 322 to drive the first impeller 31 to rotate. A first fixed disk 323 is provided at one end of the first rotation drive shaft 321 away from the first impeller 31, and 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 in the vortex generating cylinder 1, and the first impeller rotation drive motor 32 and the first blade angle adjustment motor 33 are both in the central area of ​​the vortex in the vortex generating cylinder 1, reducing the disturbance to the water flow.

[0079] The first blade angle adjustment motor 33 has a first blade angle adjustment shaft 331, and the first blade angle adjustment shaft 331 is provided with a first external thread 3311. The first moving body 34 is provided with a first internal thread 341, and 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 is threadedly matched with the first internal thread 341 on the first moving body 34, so as to drive the first moving body 34 to move up and down relative to the first impeller shell 311, so as 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 blade 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 when the first impeller 31 rotates, the first blade angle adjustment motor 33 can drive the first blade angle adjustment shaft 331 to rotate, and the rotation of the first rotation drive shaft 321 and the first impeller 31 does not affect the independent action of the first blade angle adjustment motor 33.

[0081] like Figure 6 , Figure 7 , Fig.10 and Fig.11 As shown, the second impeller rotation drive motor 36 and the second blade angle adjustment motor 37 are both shaft 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. The second rotation drive shaft 361 is connected to the second impeller shell 311 of the second impeller 35 through a hollow second rotation drive connecting shaft 362 to drive the second impeller 35 to rotate. A second fixed disk 363 is provided at one 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 overlapped along the axial direction of the second impeller rotation drive motor 36, reducing the space occupied in the vortex generating cylinder 1, and the second impeller rotation drive motor 36 and the second blade angle adjustment motor 37 are both in the central area of ​​the vortex in the vortex generating cylinder 1, 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 outer thread 3711 is arranged on the second blade angle adjustment shaft 371, and a second inner thread 381 is arranged on the second movable body 38. The second outer 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 then threadably cooperates with the second inner 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 blade 312, the second moving body 38, the second blade angle adjustment motor 37, and the second blade angle adjustment shaft 371 will all rotate synchronously with the second rotation drive shaft 361. If the deflection angle of the second blade 312 needs to be adjusted when the second impeller 35 rotates, the second blade angle adjustment motor 37 can drive the second blade angle adjustment shaft 371 to rotate, and the rotation of the second rotation drive shaft 361 and the second impeller 35 does not affect the independent action 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 controllability of the vortex can be improved through the first impeller and the second impeller, and the range of simulated vortex styles and intensity levels can be expanded.

[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 rotation drive shaft 321 and the second rotation drive shaft 361 are rotatably connected to the corresponding bracket 6 through bearings, the first impeller rotation drive motor 32 and the second impeller rotation drive motor 36 are fixedly connected to the corresponding bracket 6, and the coupling 39 is fixedly connected to the corresponding bracket 6.

[0086] Each bracket 6 includes a plurality of support rods arranged in a circumferential manner on the inner wall of the vortex generating tube 1. This structural form can reduce the obstruction to the water in the vortex generating tube 1. For example, the number of support rods in each bracket 6 is 2 to 4, and the support rods can be round rods or flat plates. When the support rods are flat plates, the support rods can be arranged obliquely along the flow direction of the water flow.

[0087] like Figure 1 As shown, the eddy current detection assembly 4 includes a flow meter 41 and a pressure sensor 42 disposed on the eddy current generating cylinder 1 and located 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 the flow meter 41 and the pressure sensor 42 can be one or more, for example, a plurality of flow meters 41 and a plurality of pressure sensors 42 are arranged at intervals along the circumferential direction of the eddy current generating cylinder 1, so that more reliable eddy current parameters can be obtained by collecting a plurality of 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 may 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 can adjust 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, the flow rate and pressure of the water pumped into the vortex generating tube 1 by the water pump 21, and control the vortex by adjusting the parameters of at least some of the above elements, obtain vortices of different styles and intensity levels, and realize the conversion between different vortices, improve the controllability of the vortex, and expand the range of intensity levels of the simulated vortex. At the same time, the formation speed of the vortex can be increased by reasonable optimization of the control strategy, and the experience of diving sports can be improved.

[0091] For example, in the startup phase, at the beginning of the gradual formation of the vortex, the controller 5 controls one of the first impeller 31 and the second impeller 35 to rotate, forming 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 the normal load range to avoid the situation where the motor is overloaded.

[0092] For another example, after the vortex in the vortex generating cylinder is maintained at a certain intensity level, when it is necessary to increase the intensity level of the vortex, the intensity level of the vortex can be increased by increasing the pumping pressure of the water pump, increasing the rotation speed of the first impeller, increasing the rotation speed of the second impeller, or by changing the deflection angle of the first blade or the second blade; accordingly, when it is necessary to reduce the intensity level of the vortex, the intensity level of the vortex can be reduced by reducing the pumping pressure of the water pump, reducing the rotation speed of the first impeller, reducing the rotation speed of the second impeller, or by changing the deflection angle of the first blade or the second blade. The present 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 of vortex ocean currents in the real environment can be simulated, so as to carry out simulated training under dangerous conditions of sudden changes in the vortex intensity level, thereby improving the diving training effect and the experience of diving sports.
