Description

Technical Field

[0001] The invention relates to the technical field of swimming pool equipment, and in particular to a laminar propeller and a swimming pool. Background Art

[0002] Laminar flow propellers have been widely used in swimming pools, especially in infinity pools. Laminar flow propellers suck the water in the pool into the machine to do work and then push it out. Swimmers can swim forward in the narrow space of the pool with the help of the water flow, so that swimmers can achieve the purpose of swimming and fitness in the countercurrent. The existing laminar flow propellers, due to the defects involved in the internal structure, not only have a low flow rate of the water flow finally pushed out by the propeller, but also make swimmers feel that the water flow is sometimes large and sometimes small, and it is easy to swing left and right, which greatly reduces the swimming experience. Summary of the invention

[0009] Wherein, the first flow stabilizer and the second flow stabilizer both have a blade assembly, the blade assembly is coaxially arranged with the propeller, and when the propeller rotates, the blade assembly is in a stationary state.

[0010] Wherein, the blade assembly includes a plurality of sub-blades, and the plurality of sub-blades extend from the blades toward the water inlet.

[0011] Wherein, the driving assembly includes a hydraulic motor, the hydraulic motor is provided with a rotating shaft, the propeller is fixed to the rotating shaft, and the rotating shaft passes through the center of the blade assembly.

[0012] The flow-pushing base further comprises a propeller duct, the propeller is arranged in the propeller duct, and the first flow stabilizer and the second flow stabilizer are respectively arranged on both sides of the propeller duct.

[0013] Wherein, both the first rectifier and the second rectifier have a honeycomb plate.

[0025] Hereinafter, with reference to the accompanying drawings, the preferred embodiments of the present invention will be described in detail. In the following description, the same symbols are given to the same components, and repeated descriptions are omitted. In addition, the accompanying drawings are only schematic diagrams, and the ratio of the dimensions of the components or the shapes of the components may be different from the actual ones.

[0026] like Figures 1 to 5 As shown, the present embodiment relates to a laminar flow propeller 1. The laminar flow propeller 1 includes a flow-pushing base portion 10 and a flow-pushing machine head portion 20. The flow-pushing base portion 10 includes a water inlet 11, a driving assembly 12, a first flow stabilizer 13, a propeller 14, a second flow stabilizer 15, and a first rectifier 16. The driving assembly 12 is used to drive the propeller 14 to rotate. The propeller 14 is arranged between the first flow stabilizer 13 and the second flow stabilizer 15. The second flow stabilizer 15 is arranged between the propeller 14 and the first rectifier 16. The first flow stabilizer 13 is arranged close to the water inlet 11.

[0027] Further, the flow pusher head 20 includes a water outlet 21, a deflector 22 and a second rectifier 23. The second rectifier 23 is arranged at the water outlet 21. The deflector 22 includes a plurality of deflectors 221. The deflector 221 has a flat section 2211 and an extension section 2212. The flat section 2211 is arranged close to the second rectifier 23, and the flat section 2211 is arranged perpendicular to the second rectifier 23. Specifically, the flat section 2211 and the extension section 2212 on the same deflector 221, the flat section 2211 is closer to the second rectifier 23 than the extension section 2212.

[0028] Further, the flow pusher head 20 is arranged on the flow pusher base 10. The flat section 2211 is arranged parallel to the first rectifier 16. The extension section 2212 extends toward the first rectifier 16, and the extension section 2212 is arranged close to the first rectifier 16. The second rectifier 23 is arranged perpendicular to the first rectifier 16. Specifically, the flat section 2211 and the extension section 2212 on the same guide plate 221, the extension section 2212 is closer to the first rectifier 16 than the flat section 2211.

[0029] In this case, the driving component drives the propeller to rotate and generates suction, so that water flows in from the water inlet, and the water flows through the first stabilizer, the propeller, and the second stabilizer in sequence. In this process, the first stabilizer and the second stabilizer can significantly eliminate the turbulent structure generated by the propeller, so that the water flows through the first rectifier and completes the first-level rectification. Since the extension section is close to the first rectifier, the water flow after the first-level rectification can be prevented from generating a large number of turbulent structures again. Therefore, the water flow can quickly change the flow direction after passing through the extension section and the flat section and complete the second-level rectification through the second rectifier, eventually forming a uniform and stable water flow flowing out of the water outlet.

[0030] In this embodiment, the flow-pushing machine head 20 is connected and fixed to the flow-pushing base portion 10. In the working state, the flow-pushing machine head 20 is located above the flow-pushing base portion 10. The water inlet 11 is located at the bottom of the laminar flow propeller 1. Specifically, water flows in from the water inlet 11, flows upward and changes the flow direction of 90° to flow out from the second flow stabilizer 23.

[0031] In this embodiment, the first flow stabilizer 13 and the second flow stabilizer 15 both have blade assemblies (131, 151). The blade assemblies (131, 151) are coaxially arranged with the propeller 14, and when the propeller 14 rotates, the blade assemblies (131, 151) are in a stationary state. Thus, the turbulent structure generated by the propeller can be effectively cut off by the stationary blade assemblies arranged on both sides of the propeller.

[0032] In this embodiment, the blade assembly (131, 151) includes a plurality of sub-blades (not shown). The plurality of sub-blades extend in the direction of the water inlet 11. This is conducive to cutting off the turbulent structure.

[0033] In this embodiment, a plurality of blades are arranged at equal angles.

[0034] In this embodiment, the driving assembly 12 includes a hydraulic motor. The hydraulic motor is provided with a rotating shaft 121. The propeller 14 is fixed to the rotating shaft 121. The rotating shaft 121 passes through the center of the blade assembly (131, 151).

[0035] In this embodiment, the flow-propelling base 10 further includes a first bearing seat 17 and a second bearing seat 18. The first bearing seat 17 is disposed below the first flow stabilizer 13, and the second bearing seat 18 is disposed above the second flow stabilizer 15. The first bearing seat 17 and the second bearing seat 18 are used to support both ends of the rotating shaft 121 and enable it to rotate in a centered manner.

[0036] In this embodiment, the flow-pushing base portion 10 further includes a propeller duct 19. The propeller duct 19 includes a base 191. The base 191 has a circular hole 192 at its center. The base 191 is used to block the water flow entering from the water inlet 11, so that the water flow flows through the circular hole 192. The propeller 14 is disposed in the circular hole 192. The first flow stabilizer 13 and the second flow stabilizer 15 are respectively disposed on both sides of the base 191. In this case, it is beneficial for the first rectifier and the second rectifier to stabilize the water flow flowing through the propeller.

[0037] In this embodiment, the first rectifier 16 and the second rectifier 23 both have a honeycomb plate. The equivalent aperture of the holes of the honeycomb plate is D. The thickness of the honeycomb plate is T. Preferably, T=5-10D.

[0038] In this embodiment, the water inlet 11 also has a honeycomb hole structure. The water inlet 11 is provided with a mounting fixture having a honeycomb hole structure. The mounting fixture may be semi-cylindrical.

[0039] In this embodiment, the flow-propelling base 10 further includes a first shell 111. The water inlet 11 and the first rectifier 16 are respectively disposed at both ends of the first shell 111. The driving assembly 12, the first flow stabilizer 13, the propeller 14, and the second flow stabilizer 15 are all disposed inside the first shell 111.

[0040] In this embodiment, the laminar propeller 1 further includes a wall-mounted structure 30. The wall-mounted structure 30 is disposed on the flow-pushing machine head 20. The wall-mounted structure 30 allows the laminar propeller 1 to be hung at a specified position. Specifically, the wall-mounted structure 30 allows the laminar propeller 1 to be hung on the side wall of the swimming pool. The wall-mounted structure 30 can be fixed to the flow-pushing machine head 20. The wall-mounted structure 30 can have a bracket. The bracket can be provided with a mounting hole. The mounting hole is used to fix the wall-mounted structure 30 at a specified position.

[0041] In this embodiment, the guide vanes 221 are arranged at equal intervals.

[0042] In some examples, the lengths of the flat sections 2211 of the guide plates 221 may be different. In some examples, the guide plates 221 may not be provided with the flat sections 2211 but only with the extension sections 2212 due to space limitations.

[0043] In some examples, the number of guide vanes 221 is n. n = 2.13X (r / b) -1 , r is the curvature of the extension section 2212, b is the width of the flow-pushing machine head 2, specifically, the flow-pushing machine head 2 may have a second shell 24, b is the width of the second shell 24. Preferably, r / b=0.2, and the number of guide vanes is 7≤n≤11.

[0044] In this embodiment, the extension section 2212 is arc-shaped. The curvature radius of the extension section 2212 is r, and the length of the flat section 2211 is L, where L=1.2r. In this case, the mutual interference between the water flows separated by the guide plates can be significantly weakened, thereby increasing the flow rate.

[0045] like Figure 6 As shown, the present invention also provides a swimming pool 100. The swimming pool 100 includes the laminar propeller 1 as described above. The specific implementation of the laminar propeller 1 is not described here. The swimming pool 100 has a side wall 110, the laminar propeller 1 is suspended on the side wall 110, and the second rectifier 23 faces the direction away from the side wall 110. In this case, the driving component drives the propeller to rotate and generates suction, so that the water flows in from the water inlet, and the water flows through the first stabilizer, the propeller, and the second stabilizer in sequence. In this process, the first stabilizer and the second stabilizer can significantly eliminate the turbulent structure generated by the propeller, so that the water flows through the first rectifier and completes the primary rectification. Since the extension section is close to the first rectifier, it can avoid the water flow after the primary rectification from generating a large number of turbulent structures again. Therefore, the water flow can quickly change the flow direction after the extension section and the flat section and complete the secondary rectification through the second rectifier, and finally form a uniform and stable water flow flowing out of the outlet.

[0046] In some examples, pool 100 may be an infinity pool.

[0047] The above-mentioned implementation modes do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-mentioned implementation modes shall be included in the protection scope of the technical solution.
