Description

Technical Field

[0001] This invention relates to the field of switch technology, and more particularly to a switch device and method for circulating water in swimming pools. Background Technology

[0002] With the popularization of the national fitness concept and the booming development of the cultural tourism industry, the construction scale of commercial and home swimming pools continues to expand. As a core link in ensuring water quality safety and realizing water resource recycling, the operational stability, ease of operation and maintenance, and environmental protection and energy saving of swimming pool circulation systems have become the core focus of the industry. As a key component for controlling water flow and regulating water pressure, the performance of the circulation switch device directly determines the operating efficiency, water quality protection effect, and energy consumption level of the swimming pool circulation system. However, existing swimming pool circulation switch devices still have many problems that need to be solved in practical applications, making it difficult to meet the current development needs of environmental protection, energy saving, and intelligent operation and maintenance. Existing devices have poor compatibility in pressure stabilization and high energy consumption. Traditional swimming pool circulation switches mostly use manual adjustment of valve opening to control water pressure, requiring maintenance personnel to monitor water flow fluctuations in real time and operate manually. This not only results in high operation and maintenance costs but also makes it impossible to quickly adapt to scenarios such as circulation pump start-up and shutdown, pool water replenishment, and multiple people entering the water. The instantaneous changes in water flow make unattended operation difficult. Existing devices lack efficient self-cleaning functions, easily leading to blockages and cumbersome maintenance. Pool circulating water contains impurities such as hair, silt, and suspended solids. The outlet channels of existing switching devices often lack targeted cleaning structures. After long-term use, impurities easily adhere to and accumulate on the inner wall of the outlet, causing poor water flow and abnormal pressure, which in turn affects the operating efficiency of the circulation system. Existing devices have low functional integration and poor coordination. In existing technologies, functions such as pressure stabilization and cleaning are mostly designed as independent modules, requiring multiple independent drive structures to be added inside the valve body. This not only makes the valve body structure complex and difficult to manufacture and assemble, but also increases the size and manufacturing cost of the equipment. At the same time, each functional module operates independently and cannot achieve coordinated linkage according to changes in water flow conditions, making it difficult to adapt to the long-term continuous circulation operation requirements of the pool and not in line with the current development trend of equipment integration and environmental protection. Therefore, we propose a switching device and method for pool circulating water. Summary of the Invention

[0013] Preferably, a method for switching on / off a swimming pool circulating water system includes the following steps:

[0014] S1: The circulating water of the pool enters the vertical channel of the valve body through the inlet hole, and the electric switch plug is ready to control the on / off state.

[0015] S2: The water flow impacts the one-way blade on the positioning rod, causing the positioning rod to rotate in the forward direction under the limit of the ratchet and pawl.

[0016] S3: Driven by the locking block and sliding groove, the protrusion and threaded groove, the double cleaning frame is rotated to scrape the impurities in the water outlet, and the impurities are discharged with the water flow.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0020] 1. This invention proposes a switching device and method for swimming pool circulating water. The device uses a push plate inside a buffer hole where water flow impacts the pump. A push rod and rack drive a gear and bevel gear set to drive the rotating ring and sealing plate to open and close. When the water flow impact force is large, the opening increases to reduce pressure; when the impact force is small, the spring resets, reducing the opening to maintain pressure. This automatically adapts to water flow fluctuations in various scenarios, such as starting and stopping the swimming pool circulating pump and water replenishment, without requiring real-time manual adjustment. It is suitable for the unattended operation needs of commercial and home swimming pools. The constant outlet water pressure effectively protects the core equipment of the swimming pool circulating system, preventing damage to the filter sand tank and pipe interfaces due to excessively high water pressure, or problems caused by excessively low water pressure leading to idling and overheating of the circulating pump and reduced efficiency of the disinfection heating device. This significantly extends the service life of the entire circulating system. Stable water flow pressure ensures uniform effects in subsequent water treatment processes such as filtration and disinfection, improving the swimming pool water quality compliance rate. Compared to traditional manual or electrically controlled pressure regulating devices, this device has a simpler structure, lower cost, and requires no electricity, making it suitable for the safe operation requirements of humid swimming pool environments.

[0021] 2. This invention proposes a device and method for switching on / off swimming pool circulating water. The water flow impacts the unidirectional impeller blades on the positioning rod, which, under the limiting effect of a ratchet and pawl, drive the connecting plate to rotate. Through the transmission cooperation of a locking block, sliding groove, protrusion, and threaded groove, the dual cleaning frames rotate synchronously to scrape impurities from the inner wall of the water outlet. The impurities are discharged with the water flow. No additional motors, cylinders, or other driving components are required; self-cleaning is achieved entirely through the flow of water. This method is suitable for the humid and chlorine-rich environment of swimming pools, has a low failure rate, and is energy-efficient. For scenarios where the circulating water contains hair, sediment, and other impurities, it can remove impurities adhering to the hole wall in real time, preventing problems such as poor water flow and abnormal pressure caused by blockage of the water outlet from the root. It reduces the frequency of manual disassembly and cleaning, lowers the workload and maintenance costs for maintenance personnel, and avoids damage to the sealing structure during disassembly. The synchronous operation of the dual cleaning frames expands the cleaning coverage area, improves cleaning thoroughness, and ensures long-term unobstructed water flow.

[0022] 3. This invention proposes a switching device and method for swimming pool circulating water. Powered by water flow, the devices operate synchronously without interference. When the flow rate fluctuates, the pressure stabilization opening adjustment and cleaning intensity are automatically matched and linked. This eliminates the need for independent cleaning and pressure stabilization drive structures within the valve body, simplifying the internal layout and reducing manufacturing, assembly difficulty, and production costs. When the swimming pool circulating water flow rate increases and the impurity content increases simultaneously, the pressure stabilization mechanism reduces pressure while simultaneously increasing the cleaning intensity, ensuring both stable pressure and smooth water flow. This coordinated operation reduces the independent operational losses of each functional module, further improving the overall reliability of the device, reducing the probability of failure, and adapting to the long-term continuous circulation requirements of swimming pools. It eliminates the need for frequent switching of functional modes, reducing mechanical wear, extending the device's service life, and lowering subsequent maintenance costs, thereby enhancing the product's market competitiveness.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Example 1, such as Figure 1 - Figure 7As shown, a swimming pool circulating water switch device includes a valve body 1. A pressure stabilizing mechanism 2 is disposed inside the valve body 1. The pressure stabilizing mechanism 2 includes a support frame 201. A rotating rod 202 is rotatably connected to the inner surface of the support frame 201 via a bearing. A first bevel gear 203 is fixedly connected to the outer surface of the rotating rod 202. A fixing plate 204 is fixedly connected to the outer surface of the valve body 1. A sealing plate 205 is rotatably connected to the outer surface of the fixing plate 204 via a bearing. A rotating ring 206 is rotatably connected to the outer surface of the fixing plate 204. A connecting rod 207 is rotatably connected between 06 and sealing plate 205 via a bearing. A rotating plate 208 is fixedly connected to the outer surface of rotating ring 206. An incomplete toothed ring 209 is fixedly connected to the outer surface of rotating plate 208. A connecting rod 210 is rotatably connected to the outer surface of fixed plate 204 via a bearing. A first gear 211 and a second bevel gear 212 are fixedly connected to the outer surface of connecting rod 210. The first gear 211 and the incomplete toothed ring 209 are meshed together. The first bevel gear 203 and the second bevel gear 212 are meshed together.

[0034] The effect achieved by the entire embodiment 1 is that the rotating rod 202 and the first bevel gear 203 on the rod rotate synchronously. The first bevel gear 203 meshes with the second bevel gear 212 on the connecting rod 210, transmitting the rotational power of the rotating rod 202 to the connecting rod 210, driving the connecting rod 210 and the first gear 211 on the rod to rotate. The first gear 211 meshes with the incomplete toothed ring 209 on the rotating ring 206, driving the rotating ring 206 to rotate on the outer surface of the fixed plate 204. At this time, the limiting block 19 on the fixed plate 204 slides along the limiting groove 9 of the rotating ring 206, thereby limiting the rotation direction and stroke of the positioning ring. During the rotation of the rotating ring 206, the sealing plate 205 is driven to rotate on the surface of the fixed plate 204 through the connecting rod 207, ultimately increasing the opening of the sealing plate 205, thereby increasing the flow area to reduce water pressure.

[0035] Example 2, as Figure 1 - Figure 7 As shown, a buffer hole 4 is provided on the inner surface of the valve body 1. A push plate 5 and a push rod 6 are slidably connected to the inner surface of the buffer hole 4. The push plate 5 and the push rod 6 are fixedly connected. A rack 7 is fixedly connected to the outer surface of the push rod 6. A second gear 8 is fixedly connected to the outer surface of the rotating rod 202. The second gear 8 is meshed with the rack 7. A limit block 19 is fixedly connected to the outer surface of the fixed plate 204. A limit groove 9 is provided on the outer surface of the rotating ring 206. The limit block 19 is slidably connected to the limit groove 9. A spring 10 is fixedly connected between the push plate 5 and the buffer hole 4.

[0036] The effect achieved by the entire embodiment 2 is that the water flow directly impacts the push plate 5 inside the buffer hole 4. The magnitude of the water flow impact force directly determines the degree to which the push plate 5 compresses the spring 10. When the water flow impact force is large, the push plate 5 experiences increased thrust, compressing the spring 10 and causing the push rod 6, which is fixedly connected to it, to slide into the valve body 1. When the push rod 6 slides, the rack 7 on its outer surface moves synchronously. The rack 7 drives the second gear 8, which meshes with it, to rotate. The second gear 8 is fixed on the rotating rod 202. When the water flow impact force is small, the restoring force of the spring 10 pushes the push plate 5 to slide in the opposite direction, causing the push rod 6 and rack 7 to move in the opposite direction. Through the reverse transmission of the aforementioned gears and bevel gears, the rotating ring 206 is driven to rotate in the opposite direction, thereby pulling the sealing plate 205 to reduce the opening, thereby reducing the flow area to ensure stable water pressure.

[0037] Example 3, as Figure 1 - Figure 7 As shown, a cleaning mechanism 3 is also provided inside the valve body 1. The cleaning mechanism 3 includes a positioning rod 301, a blade 302 fixedly connected to the outer surface of the positioning rod 301, a connecting plate 303 fixedly connected to the outer surface of the positioning rod 301, a locking block 304 fixedly connected to the outer surface of the connecting plate 303, a positioning groove 305 opened on the inner surface of the valve body 1, a moving frame 306 slidably connected to the inner surface of the positioning groove 305, a sliding groove 307 opened on the outer surface of the moving frame 306, the locking block 304 slidably connected to the sliding groove 307, a first cleaning frame 308 fixedly connected to the other end of the moving frame 306, a water inlet 309 and a water outlet 310 opened on the inner surface of the valve body 1, the first cleaning frame 308 movably connected to the water outlet 310, a support rod 11 rotatably connected to the inner surface of the water outlet 310 via a bearing, and the outer surface of the support rod 11... A mounting bracket 12 is fixedly connected to the surface of the valve body 1. Telescopic rods 13 are fixedly connected to both ends of the outer surface of the mounting bracket 12. The output ends of the two telescopic rods 13 are rotatably connected to positioning blocks 14 via rotating shafts. A second cleaning bracket 15 is movably connected to the inner surface of the water outlet 310. Arc grooves 16 are opened on the outer surfaces of the first cleaning bracket 308 and the second cleaning bracket 15. The two positioning blocks 14 are slidably connected to the arc grooves 16. Protrusions 17 are fixedly connected to the outer surfaces of the first cleaning bracket 308 and the second cleaning bracket 15. Threaded grooves 18 are opened on the inner surface of the water outlet 310. The two protrusions 17 are slidably connected to the threaded grooves 18. The positioning rod 301 is rotatably connected to the valve body 1 via bearings. The water outlet 310 is connected to the water inlet 309. The support frame 201 is fixedly connected to the valve body 1. The fixing plate 204 is fixedly connected to the support frame 201.

[0038] The overall effect of embodiment 3 is that the water flow impacts the one-way impeller blades 302 on the positioning rod 301 installed in the vertical channel. Because the connection between the positioning rod 301 and the valve body 1 is provided with a ratchet and pawl structure, this structure restricts the positioning rod 301 to rotate only in the forward direction. The reverse water flow cannot drive it to rotate. When the positioning rod 301 rotates in the forward direction, the connecting plate 303 on its outer surface rotates synchronously. The locking block 304 on the connecting plate 303 slides along the slide groove 307 of the moving frame 306, thereby driving the moving frame 306 to perform reciprocating linear motion along the positioning groove 305 of the valve body 1. During the movement of the moving frame 306, it pushes the first cleaning frame 308 closer to the water outlet 310. The protrusions on the outer surface of the first cleaning frame 308 17 then slides along the pre-set threaded groove 18 on the inner wall of the water outlet 310. Under the guidance of the threaded groove 18, the first cleaning frame 308 rotates as it moves toward the water outlet 310. At the same time, the first cleaning frame 308 drives the positioning block 14 to slide through the arc groove 16 on its outer surface. The positioning block 14 drives the telescopic rod 13 connected to it to extend and retract. The extension and retraction of the telescopic rod 13 causes the mounting frame 12 and the second cleaning frame 15 to rotate synchronously. In the rotating state, the first cleaning frame 308 and the second cleaning frame 15 are in close contact with the inner wall of the water outlet 310 to scrape off the hair, mud and other impurities attached to the inner wall of the water outlet 310. The scraped-off impurities are discharged with the water flow, thereby realizing the self-cleaning of the water outlet 310.

[0039] like Figure 1 - Figure 7 As shown, a method for switching on / off a swimming pool circulating water system includes the following steps:

[0040] S1: The circulating water of the pool enters the vertical channel of the valve body 1 through the inlet hole 309, and the electric switch plug is ready to control the on / off state.

[0041] S2: The water flow impacts the one-way blade 302 on the positioning rod 301, which drives the positioning rod 301 to rotate in the forward direction under the limit of the ratchet and pawl.

[0042] S3: Through the transmission of the locking block 304, the sliding groove 307, the protrusion 17 and the threaded groove 18, the double cleaning frame is driven to rotate and scrape the impurities in the water outlet 310, and the impurities are discharged with the water flow.

[0043] S4: The water flow impact buffer hole 4 and push plate 5 drive the sealing plate 205 to open and close through gear and bevel gear transmission, adaptively adjusting the opening degree to stabilize the pressure.

[0044] S5: The electric switch plug moves up and down to block and open the water outlet 310, completing the stable delivery and on / off control of circulating water.

[0045] Working principle: After the circulating water from the pool enters the pre-set vertical channel inside the valve body 1 through the inlet 309, it works in conjunction with the electric switch plug in the upper part of the vertical channel to control the flow. The water flow impacts the one-way impeller blade 302 on the positioning rod 301 installed in the vertical channel. Because the connection between the positioning rod 301 and the valve body 1 is equipped with a ratchet and pawl structure, this structure restricts the positioning rod 301 to rotate only in the forward direction. The reverse water flow cannot drive it to rotate. When the positioning rod 301 rotates in the forward direction, the connecting plate 303 on its outer surface rotates synchronously. The locking block 304 on the connecting plate 303 slides along the slide groove 307 of the moving frame 306, thereby driving the moving frame 306 to perform reciprocating linear motion along the positioning groove 305 of the valve body 1. During the movement of the movable frame 306, the first cleaning frame 308 is pushed closer to the water outlet 310. The protrusion 17 on the outer surface of the first cleaning frame 308 then slides along the pre-set threaded groove 18 on the inner wall of the water outlet 310. Guided by the threaded groove 18, the first cleaning frame 308 rotates as it moves towards the water outlet 310. Simultaneously, the first cleaning frame 308 drives the positioning block 14 to slide through the arc-shaped groove 16 on its outer surface. The positioning block 14 drives the connected telescopic rod 13 to extend and retract. The extension and retraction of the telescopic rod 13 causes the mounting frame 12 and the second cleaning frame 15 to rotate synchronously. In the rotating state, the first cleaning frame 308 and the second cleaning frame 15 scrape against the inner wall of the water outlet 310, thus... Hair, mud, and other impurities adhering to the inner wall of the water outlet 310 are scraped off and discharged with the water flow, thus achieving self-cleaning of the water outlet 310 and preventing impurities from clogging and affecting water output. At the same time, the water flow directly impacts the push plate 5 in the buffer hole 4. The magnitude of the water flow impact force directly determines the degree to which the push plate 5 compresses the spring 10. When the water flow impact force is large, the pushing force on the push plate 5 increases, compressing the spring 10 and driving the push rod 6, which is fixedly connected to it, to slide into the valve body 1. When the push rod 6 slides, the rack 7 on its outer surface moves synchronously. The rack 7 drives the second gear 8, which meshes with it, to rotate. The second gear 8 is fixed on the rotating rod 202, thereby driving the rotating rod 202 and the first bevel gear 203 on the rod to rotate synchronously. The first bevel gear 203 meshes with the second bevel gear 212 on the connecting rod 210, transmitting the rotational power of the rotating rod 202 to the connecting rod 210, causing the connecting rod 210 and the first gear 211 on the rod to rotate. The first gear 211 meshes with the incomplete toothed ring 209 on the rotating ring 206, driving the rotating ring 206 to rotate on the outer surface of the fixed plate 204. At this time, the limiting block 19 on the fixed plate 204 slides along the limiting groove 9 of the rotating ring 206, thereby limiting the rotation direction and stroke of the positioning ring. During the rotation of the rotating ring 206, the sealing plate 205 is driven to rotate on the surface of the fixed plate 204 through the connecting rod 207, ultimately increasing the opening of the sealing plate 205, thereby increasing the flow area to reduce water pressure.When the water flow impact force is small, the return force of spring 10 pushes push plate 5 to slide in the opposite direction, causing push rod 6 and rack 7 to move in the opposite direction. Through the reverse transmission of the aforementioned gears and bevel gears, the rotating ring 206 rotates in the opposite direction, thereby pulling the sealing plate 205 to reduce the opening, thus reducing the flow area to ensure stable water pressure. At the same time, the electric switch plug in the upper part of the vertical channel can directly achieve complete blocking or complete opening of the outlet hole 310 by moving up and down, completing the stable delivery and on / off control of the pool circulating water.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
