Description

Technical Field

[0001] The invention relates to the technical field of swimming pool equipment, in particular to a water flow propeller device and a manufacturing method thereof. Background Art

[0002] As a popular place for fitness and leisure, swimming pools continue to attract a large number of enthusiasts. In modern swimming pool design, a popular trend is to deploy swimming pool water pushers at the bottom of the pool. The equipment absorbs water from the bottom of the pool and pushes it upward to the surface area, pulling the water flow and spraying it to the surface. With the help of swimming pool water pushers, the pleasure and experience of swimming can be greatly improved.

[0003] However, the existing swimming pool water pushing equipment has many defects. First, the equipment is not removable. The existing equipment generally adopts an integrated structure of water inlet, water outlet and driving water pump; this fixed installation method greatly limits the flexibility and maintainability of the equipment. Once the equipment fails or needs maintenance, due to its non-removable characteristics, the staff often need to spend more time and energy to carry out maintenance, which not only increases the maintenance cost, but also may cause the equipment to be unable to be used normally for a long time, affecting the normal use of the swimming pool. In addition, long-term fixed installation may also cause dirt and impurities to accumulate around the equipment, further increasing the difficulty of cleaning.

[0004] Secondly, due to the choice of production materials during the manufacturing of these water-pushing devices, they are prone to produce suspended matter after being immersed in water for a long time, such as tiny particles, flocs, foam, and possible chemical residues. These suspended matter not only affects the clarity of the water and reduces the swimming experience, but more importantly, they may bring potential health risks to people who swim in the water for a long time; the tiny particles in the suspended matter may irritate the skin and cause allergic reactions; and the chemical residues may cause long-term harm to the human body.

[0030] The following will be combined with the drawings in the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The components of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed for protection, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] The following is combined with Figures 1 to 8 The specific implementation methods of the present application will be described in detail.

[0032] Figure 1 An exemplary structural diagram of a water current propeller device according to some embodiments of the present application is shown. As shown in the figure, the device may include a water current propeller mechanism, which is provided with a water inlet mechanism 1, a connecting mechanism 2 and a reducing pipe water outlet mechanism 3 connected in sequence, and the connecting mechanism 2 is also connected to a driving mechanism 4. The water inlet mechanism 1 is used to draw water from the external pool body into the pipeline, the reducing pipe water outlet mechanism is used to eject the water flow inside the pipeline out of the pool body, the connecting structure is used to connect the water inlet mechanism 1 and the reducing pipe water outlet mechanism 3, and is installed with a driving mechanism 4, which is used to provide power to suck water from the water inlet mechanism and then press it out from the water outlet mechanism to complete the water circulation movement.

[0033] refer to Figures 2 to 4 In other embodiments of the present invention, the different-diameter pipe water outlet mechanism 3 is provided with a third water inlet end 31, a water outlet channel 32, and a third water outlet end 33. Specifically, the cross-sectional area of ​​the water outlet channel 32 gradually increases from the third water inlet end 31 toward the third water outlet end 33. Since the cross-sectional area of ​​the water outlet channel 32 gradually increases from one end to the other end, it can be seen that the pipe of the water outlet channel 32 also gradually increases from one end to the other end. The gradual increase mentioned here can be that the diameter of the pipe section increases according to a fixed increasing ratio, or can be increased according to a non-fixed increasing ratio. The adopted increasing ratio does not affect the implementation of the embodiments of the present invention.

[0034] In other embodiments of the present invention, the water outlet channel 32 may be provided with a first water outlet channel 321, a second water outlet channel 322 and a third water outlet channel 323 in sequence. That is, the water outlet channel 32 may be provided in three regions with different flow rates. The number of subdivided water outlet channels and the corresponding regions described here are only for describing the incremental situation of the water outlet channel 32 in the different-diameter pipe water outlet mechanism 3 of the present invention. Further, the water outlet channel 32 may be N water outlet channel regions, where N is a natural number greater than zero. The number of subdivided water outlet channels provided after the number N is selected falls within the protection scope of the present invention.

[0035] In other embodiments of the present invention, the first water outlet channel 321 is composed of a third water inlet end 31 extending to the first water outlet channel water outlet end 3211. The third water inlet end 31 is the water inlet end of the entire different-diameter pipe water outlet mechanism 3, and in this embodiment, it is also the first water outlet channel water inlet end. At this time, in the channel area, the cross-sectional geometric figures of the third water inlet end 31 and the first water outlet channel water outlet end 3211 are the same, which is circular in this embodiment, and can also be any geometric figure such as an ellipse, a rectangle, etc. The adopted geometric figure structure does not affect the implementation of the embodiments of the present invention.

[0036] The second water outlet channel 3232 is the second water outlet channel water inlet end and the second water outlet channel water outlet end, and the second water outlet channel water inlet end is also the first water outlet channel water outlet end 3211, that is, the second water outlet channel 32 is composed of the first water outlet channel water outlet end 3211 extending to one side at an arc-shaped bending angle to the second water outlet channel water outlet end 3221, and the second water outlet channel water inlet end section and the second water outlet channel water outlet end 3221 section are different geometric cross-sections; at this time, the second water outlet channel water inlet end section is circular, and the second water outlet channel water outlet end 3221 section is rectangular, and the second water outlet channel 32 gradually increases from a circular shape along the water flow direction and transitions to a rectangular shape, and the arc-shaped bending angle ranges from 60° to 90°. In this channel, the conversion of the different diameters and directions of the entire different diameter pipe water outlet mechanism 3 is completed.

[0037] As one of the embodiments of the present invention, the first water outlet channel 321 is composed of the third water inlet end 31 extending upward at an angle ∠1 to the vertical line to the first water outlet channel water outlet end 3211, and 90°≤∠1≤100°. In this embodiment, ∠1=94° is selected.

[0038] As one of the embodiments of the present invention, the second water outlet channel 32 is composed of a first water outlet channel outlet end 3211 extending to a second water outlet channel outlet end 3221 at an arc-shaped bend angle ∠2 to one side, 60°≤∠2≤90°, and ∠2=84° is selected in this embodiment; this angle is selected so that the direction of the water flow can be changed while reducing the resistance of the pipeline to the water flow, thereby achieving a smooth transition and change of direction.

[0039] The third water outlet channel 33 has a third water outlet channel water inlet end and a third water outlet channel water outlet end, and the third water outlet channel water inlet end is also the second water outlet channel water outlet end 3221, and the third water outlet channel water outlet end is also the third water outlet end 33 of the entire different-diameter pipe water outlet mechanism 3, so the third water outlet channel 33 is formed by extending from the second water outlet channel water outlet end 3221 to the third water outlet end 33. At this time, the pipe diameter and cross-sectional changes of the channel have been completed in the second water outlet channel 32, so the cross-sectional shapes and areas of the third water outlet channel water outlet end and the third water outlet end 33 are equal, and equal to the second water outlet channel water outlet end 3221, and the flow direction and speed of the water flow can be effectively controlled by designing water outlet channels with different geometric cross-sections. The cross section of the outlet end 3211 of the first water outlet channel is circular, which can keep the water flow in a stable flow state in the initial stage; while the cross section of the outlet end 3221 of the second water outlet channel is rectangular, and the transition setting from circular to rectangular can gradually increase the cross-sectional area of ​​the water flow, thereby increasing the flow rate and flow of the water flow. In addition, the arc bending angle range is 60°~90°, which can effectively adjust the direction of the water flow into the pool body while reducing the resistance of the pipeline, avoiding excessive reduction of the water flow speed, resulting in reduced propulsion.

[0040] Specifically, the outlet end 3211 of the first water outlet channel is circular, which can reduce the turbulence of the water flow and ensure the stability of the water flow; the outlet end 3221 of the second water outlet channel is rectangular, which can increase the coverage area of ​​the water flow and improve the pushing effect of the water flow. The transition setting from circular to rectangular allows the water flow to gradually increase the cross-sectional area during the flow process, thereby increasing the flow rate and flow rate of the water flow. The arc bending angle range is 60°~90°, which can effectively adjust the direction of the water flow, so that the water flow is more evenly distributed in the swimming pool, avoiding the water flow from concentrating in a certain place and affecting the swimmer's experience. This structure can effectively solve the problem that the water flow in the existing swimming pool water pushing equipment is difficult to control the direction, strength and speed, improve the uniform distribution of the water flow in the swimming pool, and enhance the swimming experience of the swimmer. At the same time, through the design of different geometric cross-sections, the flow rate and flow rate of the water flow can be increased, the water pushing effect can be improved, and the pleasure and experience quality of swimming can be further enhanced.

[0041] In other embodiments of the present invention, a method for manufacturing a water propeller device includes a method for manufacturing a splicing assembly. In this embodiment, the splicing assembly is a different-diameter pipe water outlet mechanism 3. Since the assembly is a different-diameter pipe, it is not easy to demould by an integrated molding method, so a splicing method is used to overcome the above disadvantages. The specific steps are as follows: S1. Forming by acrylic sheet: First, heat the acrylic sheet in a forming furnace at a temperature of 150℃-210℃ for 2-5 minutes to soften the sheet; after the acrylic sheet is softened, adsorb the acrylic sheet and the surface of the component mold together to form; this step can ensure the accuracy of the shape and size of the component; here, the component mold is a left-right symmetrical half-diameter pipe water outlet mechanism 3 mold.

[0042] S2. Demolding: Demolding the molded spliced ​​components; the half-structure mold used ensures that the molded components can be smoothly taken out of the mold and are easy to demold; after demolding, proceed to the next step.

[0043] S3, fiber spraying: perform fiber spraying on the demoulding splicing components; since the strength of the acrylic board is not enough, fiber material is sprayed on the demoulding components to enhance the structural strength of the components; after the fiber spraying is completed, the sprayed material is completely cured; after the material is cured, the splicing components are cut; after the cutting operation is completed, the edges of the splicing components after cutting are polished to make the edges of the components flat and smooth; the edges of the components are polished to be flat and smooth in order to carry out the next step of splicing and bonding, so that the bonding is neat and no gaps will be generated due to the unevenness of the splicing surface, which will damage the performance of the components; after completing the above steps, proceed to the next step.

[0044] S4. Overall fiber coating: The splicing structure is bonded by adhesive materials to form a whole. After the splicing is completed, the surface of the spliced ​​parts is coated with glass fiber felt and resin to further enhance the structural strength and durability of the components.

[0045] The use of resin fiber coating technology on the outer surface not only enhances the wear resistance, corrosion resistance and aging resistance of the outer surface of the component, but also enables the components to be more tightly and firmly connected through fiber coating during installation, thereby improving the stability and reliability of the overall structure.

[0046] Specifically, in the step of forming the acrylic sheet, the temperature is controlled between 150℃-210℃ and the heating time is 2-5 minutes to ensure that the acrylic sheet is softened without being damaged. During the fiber spraying process, the thickness of the sprayed fiber material is 5-10mm to ensure the structural strength of the component. In the overall fiber coating step, glass fiber mat is used to apply resin to further enhance the durability and structural strength of the component.

[0047] Through the four steps of acrylic plate molding, demoulding, fiber spraying and overall fiber coating, the problems of complex manufacturing and insufficient structural strength of the water jet propeller device in the prior art are solved. The shape and size of the component are accurate by precisely controlling the molding temperature and time; the structural strength and durability of the component are enhanced by fiber spraying and overall fiber coating. This method improves the manufacturing efficiency and quality of the component and has high practical value.

[0048] The different-diameter pipe water outlet mechanism 3, the water inlet mechanism 1 and the flange components of the present invention are all made of acrylic plates formed by vacuum forming. This manufacturing method ensures the smoothness and flatness of the inner surface of the mechanism, effectively avoiding the potential pollution of water quality caused by rough or uneven material surfaces, thereby ensuring the hygienic standards of water use. At the same time, the smooth inner surface can also reduce the friction resistance of water flow and improve the efficiency of water flow.

[0049] Acrylic sheet is a lightweight, high-strength, easy-to-process material with good weather resistance, chemical resistance and high safety. It has excellent wear resistance, hardness and electrical insulation performance, and is green and environmentally friendly. Therefore, the present invention selects acrylic sheet as the main component material, which not only inherits these advantages, but also ensures that the pipeline or pool body will not produce pollutants under long-term water immersion, effectively keeps the water clean, and thus protects the health and safety of users.

[0050] In some other embodiments of the present invention, in step S3: First, spray n layers of mixed resin on the surface of the splicing component, with a thickness of 5-10 mm, where n≥1. After the mixed resin is cured, spray n layers of the first composite unsaturated resin on the inner cylinder surface of the splicing component, with a thickness of 1-3 mm, where n≥1. After the fiber spraying is completed, use a rolling mechanism to roll the first composite unsaturated resin layer to compact the material. Spray n layers of the second composite unsaturated resin again on the rolled inner cylinder surface, with the thickness of the second composite unsaturated resin layer controlled within the range of 3-7 mm, where n≥1. Roll the second composite unsaturated resin layer to roll and compact the material to enhance the structural strength of the component.

[0051] When spraying mixed resin, the number of spray layers and thickness can be adjusted according to actual needs to adapt to different usage environments; during the rolling process, different rolling equipment can be selected to adapt to the characteristics of different materials. In addition, the resin ratio and curing time can also be adjusted according to actual conditions to achieve optimal strength and durability.

[0052] Through multi-layer spraying and rolling treatment, the problem of insufficient material strength faced by existing swimming pool water pushing equipment during manufacturing is solved. By spraying multiple layers of mixed resin and composite unsaturated resin on the surface of the spliced ​​components and rolling them, the structural strength of the components can be effectively enhanced, avoiding the problem of suspended matter after long-term immersion in water, thereby improving the service life and stability of the equipment; ensuring the clarity of the swimming pool water quality and the health and safety of swimmers.

[0053] In a further embodiment, the mixed resin is 901-P vinyl resin containing methyl ethyl ketone; the first composite unsaturated resin is 279P unsaturated resin containing glass fiber; and the second composite unsaturated resin is 188-B unsaturated resin with glass fiber.

[0054] In other embodiments of the present invention, 901-P vinyl resin containing methyl ethyl ketone is used as a mixed resin and sprayed on the surface of the splicing component; 901-P vinyl resin containing methyl ethyl ketone (methyl ethyl ketone peroxide, referred to as MEKP) mainly refers to the curing agent used in the curing process of the resin as methyl ethyl ketone peroxide. 901-P vinyl resin is a high-performance thermosetting resin, usually synthesized by the reaction of methacrylic acid and epoxy resin (such as bisphenol A epoxy resin). In the curing process of 901-P vinyl resin, methyl ethyl ketone plays a role in initiating double bond crosslinking in the resin, thereby converting the resin from liquid to solid, forming a cured product with high strength and stability, so that the surface of the splicing component has corrosion resistance.

[0055] In other embodiments of the present invention, when setting the protective layer of the inner wall of the water outlet mechanism cylinder, 279P unsaturated polyester resin reinforced with glass fiber is used as the first composite unsaturated resin. First, 279P unsaturated polyester resin belongs to the category of unsaturated polyester resins, and its significant characteristics are low viscosity and moderate reactivity; this characteristic makes the resin easy to operate during the spraying process, and can be evenly covered on the inner wall of the cylinder to form a dense protective layer. At the same time, the moderate reactivity ensures that the resin can quickly form a stable structure during the curing process, meeting the requirements of the water outlet mechanism for material strength and durability.

[0056] As the reinforcing phase of the composite material, the low density of glass fiber enables the overall composite material to achieve a lightweight design while maintaining high strength. In addition, glass fiber is also corrosion-resistant and can effectively resist corrosion even when exposed to harsh environmental conditions such as moisture, concentrated acid, and concentrated alkali for a long time, avoiding material embrittlement or aging, thereby greatly extending the overall service life of the composite material.

[0057] Combining the advantages of glass fiber and 279P unsaturated polyester resin, the composite material not only has high strength and light weight, but also has corrosion resistance. For the water outlet mechanism, it is necessary to keep the surface smooth and easy to clean while bearing external loads such as water weight and pressure. In addition, the composite material also has water resistance and pollution resistance, which further enhances the reliability and durability of the water outlet mechanism and ensures the long-term stable operation of the water outlet mechanism.

[0058] In some other embodiments of the present invention, the second complex unsaturated resin is 188-B unsaturated resin with glass fiber.

[0059] 188-B unsaturated resin with glass fiber usually refers to a composite material that uses 188-B unsaturated resin as a base material and is reinforced by glass fiber; 188-B unsaturated resin has excellent chemical corrosion resistance and can effectively resist the erosion of the inner wall of the pipe by swimming pool water (often containing disinfectants such as chlorine) and other chemicals. This corrosion resistance ensures that the pipe will not leak or be damaged due to chemical corrosion during long-term use, thereby extending the service life of the pipe. And no harmful substances will be produced, reducing the pollution to the water body; the addition of glass fiber significantly improves the strength and toughness of the material, making the pipe more durable when subjected to external forces such as water pressure and water flow. This high strength and toughness ensures the safety and stability of the pipe during the operation of the swimming pool. Unsaturated resin has excellent process properties and can be easily brushed or sprayed on the surface of the pipe to form a uniform protective layer. This construction method is not only simple and quick, but also can ensure the uniformity and integrity of the protective layer. Since the protective layer composed of unsaturated resin and glass fiber has excellent durability and stability, the maintenance cost during use is relatively low.

[0060] As another embodiment of the present invention, when the above-mentioned splicing module is a different-diameter pipe water outlet mechanism 3, the manufacturing method that can be adopted is: First, the acrylic sheet is placed in a molding furnace and heated at 170-195° for 3-4 minutes to soften the sheet. After the acrylic sheet softens, the acrylic sheet is adsorbed together with the mold surface. The air pipe on the side of the mold is vacuum-suctioned to form the outer shape of the different-diameter pipe outlet mechanism 3; the different-diameter pipe outlet mechanism 3 is a gooseneck outlet shape, that is, it extends from one end to the other end, bends to one side in the middle, and the cross-section changes from a circle to a rectangle.

[0061] Surface fiber spraying: For the gooseneck outlet after molding and demolding, first use a spray gun to spray a layer of 901-P vinyl resin mixed with methyl ethyl ketone on the surface. After the 901-P vinyl resin is cured, use a spray gun to spray a layer of 279P unsaturated resin with glass fiber 2mm thick on the cylinder body. After the fiber spraying is completed, use a roller to roll the glass fiber to compact it, and then spray a layer of 188-B unsaturated resin with glass fiber 5mm again. Repeat the rolling of the glass fiber to enhance its structural strength.

[0062] Resin curing: Wait for the resin on the surface of the gooseneck outlet to fully cure to ensure the stability and durability of the material.

[0063] Cutting and edging: The solidified gooseneck outlet is cut and the edges are processed to facilitate subsequent splicing operations.

[0064] Smooth jointing: Use a clamp to precisely joint two semi-finished outlet products with processed edges to ensure the smoothness of the joint surface.

[0065] Overall fiber coating: After the splicing is completed, the surface of the spliced ​​outlet is coated with glass fiber felt and resin to achieve a more solid and sealed structure.

[0066] refer to Figure 5 In other embodiments of the present invention, the water inlet mechanism 1 includes a first water inlet end 11, a water inlet channel 12, and a first water outlet end 13. The cross-sectional area of ​​the water inlet channel 12 gradually decreases from the first water inlet end 11 to the first water outlet end 13. The cross-sectional area of ​​the first water inlet end 11 is rectangular, and the first water outlet end 13 is circular. The water inlet channel 12 is provided with a first water inlet channel 121, a second arc-shaped channel 122, and a third arc-shaped channel 123 in sequence. The first water inlet channel 121 is formed by extending from the first water inlet end 11 to the first water inlet channel outlet end 1211. The cross-sectional area of ​​the first water inlet channel outlet end 1211 is less than half of the cross-sectional area of ​​the first water inlet end 11. The second arc-shaped flow channel 122 is formed by extending from the first water inlet flow channel outlet end 1211 to the second arc-shaped flow channel outlet end 1221, and one side of the second arc-shaped flow channel 122 is a first arc-shaped side wall 1222. The third arc-shaped flow channel 123 is formed by extending from the second arc-shaped flow channel outlet end 1221 to the first water outlet end 13, and one side of the second arc-shaped flow channel 122 is a second arc-shaped side wall 1231. The first arc-shaped side wall 1222 and the second arc-shaped side wall 1231 are arranged on opposite sides.

[0067] In this embodiment, the cross-sectional area of ​​the water inlet channel 12 is gradually reduced from the first water inlet end 11 to the first water outlet end 13, and the first water inlet channel 121, the second curved channel 122 and the third curved channel 123 are provided. The arc design can effectively control the direction, force and speed of the water flow, while reducing the resistance generated when the water flow collides with the channel, thereby avoiding the problem of uneven water flow distribution. Specifically, the provision of the first water inlet channel 121 allows the water flow to gradually concentrate when entering the device, and the second curved channel 122 and the third curved channel 123 further adjust the direction and speed of the water flow, so that the water flow can enter the pipeline more smoothly.

[0068] As a further improvement of the embodiment of the present invention, the implementation methods of the water inlet mechanism 1 include but are not limited to the following: the cross-sectional shape of the first water inlet channel 121 can be adjusted according to actual needs, and can adopt an elliptical or other polygonal shape; the curvature and length of the second arc flow channel 122 and the third arc flow channel 123 can be set according to different water flow requirements to achieve the best water flow control effect; in addition, guide plates or other auxiliary structures can be added to the water inlet channel 12 to further optimize the distribution and speed control of the water flow. The above-mentioned technical feature selections all fall within the protection scope of the present invention.

[0069] As other embodiments of the present invention, a method for manufacturing a water propeller device includes a method for manufacturing an integrally formed component. In this embodiment, the integrally formed component includes a water inlet mechanism 1, a fixing member and a pool body. The specific steps are as follows: S1. Forming through acrylic sheet: First, place the acrylic sheet in a forming furnace at a temperature of 150℃-210℃ and heat it for 2-5 minutes to soften the sheet. After the acrylic sheet is softened, the acrylic sheet and the surface of the one-piece forming component mold are adsorbed together for forming.

[0070] S2, demoulding: demoulding the molded one-piece component; after demoulding, proceed to the next step.

[0071] S3, Fiber Spraying: Spraying resin fiber material on the surface of the one-piece molded component with a thickness of 5-10mm to enhance the structural strength of the one-piece molded component.

[0072] This method uses the heating and softening of acrylic sheets and the adsorption molding of molds to form an integrated component, which is then demoulded and sprayed to ensure the structural strength and durability of the component. Compared with traditional splicing components, the integrated component has higher strength and better sealing, reducing the risk of possible leakage.

[0073] Specifically, through acrylic sheet molding and fiber spraying, the integrated manufacturing of components can be achieved, avoiding gaps and weaknesses that may occur during the splicing process. Fiber spraying not only enhances the strength of the components, but also makes their surface smoother, reduces water flow resistance, and improves water flow propulsion efficiency.

[0074] It can be seen that the one-piece molded component manufacturing method described in the present application solves the problems of insufficient strength and poor sealing of spliced ​​components in the prior art, and significantly improves the performance and service life of the water flow propeller device.

[0075] In other embodiments of the present invention, the water inlet mechanism 1 is detachably connected to the water inlet of the connecting mechanism 2 through a fixing member 6, the water outlet of the connecting mechanism 2 is detachably connected to the reducing pipe water outlet mechanism 3 through a fixing member 6, and the middle section of the connecting mechanism 2 is also connected to a driving mechanism 4.

[0076] In other embodiments of the present invention, the driving mechanism 4 is installed in the middle section of the connecting mechanism 2. The middle section mentioned here refers to the position between the water inlet and the water outlet of the connecting mechanism 2, and does not specifically refer to the middle position. The driving mechanism 4 is selected to be installed at a section point of the connecting mechanism 2, which can absorb water and pressurize water, and does not affect the implementation of the embodiments of the present invention.

[0077] In another embodiment of the present invention, the driving mechanism 4 is an axial flow pump, and the specific installation method can be: First, fill the recessed positions of the water inlet and outlet of the axial flow pump with glass glue, then put the silicone gasket 61, and then fix the different-diameter pipe outlet mechanism 3 and the flange to the axial flow pump with bolts; Use a tooling vehicle to adjust the height of the axial flow pump to match the water outlet hole of the different-diameter pipe outlet mechanism 3, and then match the water inlet mechanism 1 with the axial flow pump, and the installation position of the tail opening of the water inlet mechanism 1 is matched with the flange; The axial flow pump and the support frame are fixed by the compensation mechanism 5. In the embodiment here, the compensation mechanism 5 can be an adjustment screw and rubber foot structure, and the axial flow pump is adjusted to be horizontal in the XY direction by the nut.

[0078] In other embodiments of the present invention, the connecting mechanism 2 is an elbow flow channel, and the elbow flow channel is provided with a second water inlet end 21 and a second water outlet end 22. The second water inlet end 21 is connected to the first water outlet end 13 through a fixing member 6, and the second water outlet end 22 is connected to the third water inlet end 31 through a fixing member 6. The elbow flow channel is provided with a third opening in the middle of the flow channel, and the third opening is connected to the driving mechanism 4. This structure adopts a detachable connection method, which significantly improves the maintainability and flexibility of the equipment and solves the limitations and cleaning difficulties brought by the traditional integrated pipeline structure. The fixing member 6 is used to connect different ports, which simplifies the maintenance and replacement process in case of failure and improves the efficiency and reliability of the equipment. In addition, the elbow flow channel optimizes the direction and distribution of water flow, enhances the ability to control water flow, and through the connection with the driving mechanism 4, more flexible water flow regulation is achieved to meet diverse usage needs.

[0079] refer to Figure 1In other embodiments of the present invention, the fixing member 6 may be a flange; in this embodiment, a plurality of small holes are provided on the outer circumference of the flange. Specifically, one side of the flange is connected to the first water outlet end 13 of the water inlet mechanism 1 by bolts, and the other side is connected to the second water inlet of the connecting mechanism 2 by bolts passing through the small holes and the silicone gasket 61; a small hole is provided on the third water inlet end 31, and is connected to the second water outlet end 22 of the connecting mechanism 2 by bolts passing through the silicone gasket 61; this structure connects the different-diameter pipe water outlet mechanism 3 to the water inlet mechanism 1 detachably; this embodiment adopts a modular design, so that the water inlet mechanism 1, the connecting mechanism 2 and the different-diameter pipe water outlet mechanism 3 can be disassembled and replaced respectively, which greatly improves the flexibility and maintainability of the equipment. Through this setting, when the equipment fails or needs maintenance, the staff can quickly disassemble the corresponding module for inspection and repair, reducing the maintenance cost and equipment downtime. When the pipeline needs to be cleaned, the components can also be disassembled for cleaning, which is convenient and simple.

[0080] In other embodiments of the present invention, the water flow propulsion device also includes a pool body 7, and the shape of the pool body 7 can be any geometric figure without hindering the implementation of this embodiment; the water flow propulsion mechanism is arranged on one side of the pool body 7, and the one side here can be any position around the pool, such as the left side, right side, upper side, lower side, corner side, etc.

[0081] In other embodiments of the present invention, the integrally formed components may be the water inlet mechanism 1 and the flange; specifically, the manufacturing method of the water inlet mechanism 1 may be: Acrylic molding: First, the shape of the water inlet mechanism 1 is manufactured using an acrylic plate through a vacuum forming process.

[0082] Surface fiber spraying: After molding, the surface of the water inlet mechanism 1 is sprayed with resin fiber material to a thickness of 7-8 mm to enhance its structural strength.

[0083] Demolding and edge punching: After the resin on the surface of the water inlet mechanism 1 is cured, it is demoulded, the edges are edge punched according to the designed size, and then a hole is opened at the edge of the first water outlet end 13 of the water inlet mechanism 1.

[0084] Structure: The tail of the water inlet mechanism 1, i.e., the first water outlet 13, adopts an arc transition shape to reduce the local resistance of the water flow when passing through the tail, thereby reducing the turbulence and eddy current of the fluid, and further reducing the loss of the water flow caused by cavitation. The arc transition setting can effectively reduce the energy loss and equipment damage caused by cavitation, and improve the efficiency and reliability of the system.

[0085] As another embodiment of the present invention, when the integrally formed component is a flange, the specific manufacturing method may be: Acrylic molding: Use acrylic sheet to perform vacuum molding of the gooseneck outlet and flange using the same mold, ensuring precise fit between components and stability of the overall structure.

[0086] Surface fiber spraying: After molding and demoulding, the flange shape is cut out, and the flange surface is coated with glass fiber felt and resin to a thickness of 7-8mm to enhance its structural strength.

[0087] Trimming and drilling: After curing, the flange is trimmed according to the designed height and the edges are drilled as required.

[0088] In other embodiments of the present invention, the first water inlet end 11 in the water flow propulsion mechanism is arranged at the bottom of the pool body 7, and the first water inlet end 11 is provided with a water inlet mask 14; the specific installation method is the existing technology and does not affect the implementation of this embodiment.

[0089] In other embodiments of the present invention, the third water outlet 33 is arranged at the upper end of the pool body 7. The upper end this time is a position defined relative to the bottom position of the pool and is not limited to the top of the pool. It only needs to be higher than the water inlet position of the water inlet mechanism 1 to be the upper end described in this embodiment.

[0090] In other embodiments of the present invention, the third water outlet 33 is provided with a water outlet mask 34 and a filter mechanism 35. The filter mechanism 35 is filled inside the third water outlet 33, and the water outlet mask 34 is snap-fitted and installed outside the third water outlet 33.

[0091] In some embodiments, the water outlet mask 34 is a laminar flow device, which can make the water flow evenly sprayed to the pool body 7.

[0092] In some embodiments, the filter mechanism 35 may be a honeycomb filter plate, a mesh filter plate or a filter structure that can filter water, all of which fall within the protection scope of the present invention; the filter mechanism 35 may be made of materials including but not limited to activated carbon, glass fiber, AFM active filter media or diatomaceous earth, etc.; the filter mechanism 35 may be a detachable structure; using components such as laminar flow devices and honeycomb filter plates to form a strong and smooth water flow, provide a smoother water outlet effect, reduce water flow loss, and thus enhance the user experience.

[0093] In a further embodiment, the detachable structure can be fixed by a slide groove and a pressure plate structure. During installation, the filter plate only needs to be docked with the pressure plate, and then pressed downward to smoothly install and fix the filter plate in the filtration system. When the swimming pool water passes through the filtration system, it will first enter the filter medium layer of the filter plate. In this layer, impurities such as suspended matter, colloids, and organic matter in the water will be effectively intercepted by the filter medium and adsorbed on its surface. Over time, a layer of impurities, namely the filter cake, will gradually form on the surface of the filter medium. The formation of the filter cake can improve the filtration efficiency to a certain extent, but it will also increase the filtration resistance. Therefore, in order to ensure the normal operation of the filtration system, the filter medium needs to be cleaned or replaced regularly; in addition, the filter mechanism 35 adopts a detachable design, The detachable structure not only improves the efficiency of installation and disassembly, making it easier to clean or replace the filter medium, but also improves the convenience of maintenance and helps to extend the overall service life of the filtration system.

[0094] refer to Figures 6 to 8 In some other embodiments of the present invention, a support frame 8 is further included, and the support frame 8 is arranged outside the pool body 7, and the water current propeller mechanism is installed on the support frame 8. The support frame 8 is provided with a first support frame 81 and a second support frame 82. The first support frame 81 is arranged outside the pool body 7 and is used to fix and support the pool body 7; the second support frame 82 is arranged on the outer wall of the pool body 7 connected to the water current propeller; it is used to fix one side of the pool body 7 and install the water current propeller. When the water current propeller is running, both the inflow and outflow of water will generate force on this side of the pool, so the second support frame 82 is arranged to play a role of reinforcement. In other embodiments of the present invention, the second support frame 82 is a triangular column-shaped support frame formed by an I-shaped steel crossbeam and a triangular support side frame 823. Specifically, the I-shaped surface of the first I-shaped crossbeam 821 abuts against the side wall of the pool, and the other I-shaped surface is connected to the triangular support side frame 823; the I-shaped surface of the second I-shaped crossbeam 822 is connected to the first support frame 81 in the ground direction, and the other I-shaped surface is connected to one side of the triangular support side frame 823; this structure can effectively offset the force of the side wall of the pool and play a role in stabilizing the pool body 7.

[0095] In other embodiments of the present invention, the driving mechanism 4 in the water propeller mechanism is connected to the support frame 8 through the driving mechanism 5; the compensation device is provided with an adjusting screw and a rubber foot structure, the driving mechanism 4 is placed on the support frame 8, and the position of the axial flow pump in the XY direction is adjusted by the nut; the structure has low cost and is easy to operate; Furthermore, the driving mechanism 5 can be implemented in a variety of other ways, such as a spring or a hydraulic device. Specifically, the spring can provide a rebound force when subjected to an external force, and selecting a spring with an adaptive stiffness can achieve a compensation effect; the hydraulic device can flexibly adjust the position and angle of the device through changes in liquid pressure to adapt to different use environments. This structure has high adjustment accuracy, but there are problems such as high cost.

[0096] The drive mechanism 5 can improve the adjustability and adaptability of the equipment; since the size of the tank body 7, the height of the support frame 8, and the size of the drive mechanism 4 are non-standard parts, there will be certain work errors during installation, so the drive mechanism 5 is provided so that the water flow propeller mechanism can adapt to various tank bodies 7, support frames 8 and other external workpieces. This fixing method of the drive mechanism 4 can provide stable support for axial flow pumps, etc., to ensure that the pump body will not shake or slide during use. It can also effectively absorb and isolate the vibration generated by the pump body during operation, reducing the interference of vibration on the operation and precise measurement of the device.

[0097] In summary, after reading the present invention document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the present invention without creative mental work, which all fall within the scope of protection of the present invention.
