Description

Technical Field

[0001] This invention belongs to the field of circulating pump technology, and specifically relates to a circulating pump control device and control system. Background Technology

[0002] A circulating pump is a type of centrifugal water pump that accelerates liquid through centrifugal force and circulates it through pipes. The principle of a circulating pump is that a motor drives the pump shaft to rotate, causing the pump impeller to rotate as well. This generates centrifugal force that draws the liquid into the pump body, and the rotating impeller pumps the liquid out through the outlet at a certain pressure. Because the outlet of the circulating pump is connected to the inlet via a pipe, the fluid, after being pumped out, can naturally form a certain flow state along the pipe, thus achieving liquid circulation. The fluid is then returned to its original source or sent to the desired location through the pipe. Circulating pumps are widely used in HVAC, air conditioning, water supply, and industrial circulation fields, mainly for fluid circulation, transfer, pressurization, and depressurization. Circulating pumps are a very important piece of equipment. However, the following disadvantages exist in the current use of circulating pumps:

[0003] 1. When the water pressure is low, it will take longer for the water to fill the pump body, which will also make the subsequent transmission time longer. Usually, a booster pump will be used in environments with low water flow, which will increase the purchase cost of the equipment, as well as the operating and maintenance costs.

[0004] 2. At the same time, circulating pumps are often used to transport hot water, which easily causes scale to form in the water. When the circulating pump is stopped, impurities enter the gap between the pump impeller and the pump body. When it is restarted, internal jamming or abnormal rotating noise may occur. This will reduce the service life of the circulating pump and make maintenance complicated. Summary of the Invention

[0005] The purpose of this invention is to provide a circulating pump control device and control system, which has the advantages of facilitating water pressurization, enabling rapid water flow, and facilitating the cleaning of internal impurities, thus preventing internal jamming of the pump body.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a circulating pump control device and control system, comprising a pump body structure, the pump body structure comprising a motor end, a shaft and a pump casing, a control structure provided at the bottom of the pump casing, a pipeline structure connecting the pump casing and the control structure, the control structure comprising a housing assembly, the housing assembly comprising a water-conducting housing and a control housing, a scraping assembly provided inside the water-conducting housing, the scraping assembly comprising a middle plate, the middle plate and the water-conducting housing being rotatably connected to each other by a waterproof bearing, a telescopic assembly provided inside the scraping assembly, the telescopic assembly comprising a movable collar, a pressure supply drive assembly provided at the top of the telescopic assembly penetrating into the interior of the control housing, the pressure supply drive assembly comprising a screw, the screw being rotatably connected to the interior of the control housing by a bearing.

[0007] Using the above technical solution, in the use of the circulating pump, the inlet pipe is connected to the external water supply equipment. The operation of the control structure generates centrifugal force inside the pump casing, thus circulating the water connected to the inlet pipe through the pipeline structure. When the water first enters the water-passing shell through the inlet pipe, it is located between the middle plate and the first moving plate. The impeller rotates due to the water flow. At this time, the scraping assembly drives the scraper to contact the inner wall of the water-passing shell, thereby descaling and cleaning the portion of the water-passing shell between the middle plate and the fixed top plate. The cleaned water containing scale is then discharged through the discharge pipe. The metal mesh removes the scale and allows it to enter the pump casing. Simultaneously, it intercepts some impurities in the water before it enters the pump casing. The moving scraper blades also contact the metal mesh, helping to remove the scale and impurities intercepted on the surface of the metal mesh. This design facilitates the entry of water into the pump casing. The water undergoes a purification process to prevent long-term circulation of hot water, as scale buildup can affect the pump impeller inside the pump casing. Water entering the pump casing then re-enters the water passage housing through the second water pipe before being discharged to the desired location via the outlet pipe. During water transfer, when the water reaches between the middle plate and the first shifting plate, the telescopic component contracts and expands in accordance with the water flow, transmitting this movement to the pressure drive component. This pressure drive component then moves the second shifting plate longitudinally, pressurizing the water about to enter the second water passage pipe, allowing it to reach the desired location more quickly. Simultaneously, the spring-loaded extension of the first shifting plate also accelerates the flow of water into the pump casing. This control device facilitates the use of the circulation pump even with low water flow, reducing the waiting time for the water to slowly fill the pump casing and reach its destination, thus promoting rapid water circulation.

[0008] The present invention is further configured such that: the motor end and the shaft are fixedly sleeved together; a fixed plate is fixedly installed at the bottom of the shaft; a ring and a pump wheel are fixedly installed at the bottom of the fixed plate; the pump wheel is located outside the ring; and both the fixed plate and the pump wheel are located inside the pump casing.

[0009] Using the above technical solution, the operation of the motor end will drive the shaft, fixed plate, ring and pump wheel to rotate, so that the ring and pump wheel will introduce water into the pump casing through the centrifugal force generated, so as to realize the circulation of the circulating pump.

[0010] The present invention is further configured such that: a mounting flange 1 is fixedly installed at the bottom of the motor end, a bolt 1 is provided at the top of the mounting flange 1 to the inside of the pump casing, a mounting flange 2 is fixedly installed at the bottom of the pump casing, a mounting flange 3 is fixedly sleeved at the top of the water-passing housing, and a bolt 2 is provided at the top of the mounting flange 2 to the inside of the mounting flange 3.

[0011] Using the above technical solution, flange one and bolt one are used to connect and install the motor end to the pump casing, while flange two and flange three and bolt two are used to secure the pump casing to the water supply casing.

[0012] The present invention is further configured such that: the pipeline structure includes a water inlet pipe, the water inlet pipe is connected to one side of the water-conducting shell, the other side of the water-conducting shell is connected to a water inlet pipe and a water outlet pipe, one end of the water inlet pipe is connected to the water inlet of the pump casing, and the water outlet of the pump casing is connected to a water outlet pipe connected to one side of the water-conducting shell.

[0013] Using the above technical solution, external water enters the water-conducting shell through the inlet pipe, then enters the pump casing through the first water-conducting pipe, and then re-enters the water-conducting shell through the second water-conducting pipe, before being discharged to the desired location through the outlet pipe.

[0014] The present invention is further configured such that: a connecting rod is fixedly installed inside the middle layer plate; the top of the middle layer plate is provided with an impeller one, a shift plate one, and a fixed top plate that are sleeved on the surface of the connecting rod in sequence; the bottom of the middle layer plate is provided with an impeller two and a shift plate two that are sleeved on the surface of the connecting rod in sequence; the impeller one and the impeller two are both fixedly sleeved with the connecting rod; the fixed top plate is fixedly connected with the connecting rod; and the fixed top plate and the water-conducting housing are rotatably connected to each other through a waterproof bearing.

[0015] Using the above technical solution, both the middle plate and the fixed top plate support the connecting rod and cooperate with its rotation. Impeller 1 and impeller 2 will rotate in the same direction due to the flow of water, and then drive the connecting rod, the middle plate, and the fixed top plate to rotate. The waterproof bearing cooperates with the fixed top plate to support it and cooperate with its smooth rotation.

[0016] The invention is further configured such that: a scraper is embedded in one side of the middle layer plate, the top of the scraper is fixedly connected to the top layer plate, a convex scraper strip is fixedly installed on one side of the scraper, and a slot is provided on one side of both the middle layer plate and the first sliding plate to accommodate the scraper. A scale discharge pipe located at the top of the middle layer plate is connected to the surface of the water-conducting shell, a control valve is installed on the scale discharge pipe, and a metal mesh is embedded in one side of the water inlet pipe.

[0017] Using the above technical solution, the scraper moves along with the middle layer plate and the fixed top layer plate, and is slidably engaged with the moving plate through the slot. During the rotation of the scraper, the convex scraper blades contact the inner wall of the water-passing shell, thereby descaling and cleaning the part of the water-passing shell between the middle layer plate and the fixed top layer plate. The cleaned water containing dirt is then discharged through the scale drain pipe. The control valve is opened and closed in coordination with the scale drain pipe. The metal mesh draws the dirt into the pump casing, and at the same time, it can also intercept some impurities in the water before it enters the pump casing. During the scraping process of the convex scraper blades, they also contact the metal mesh, which helps to remove the dirt and impurities intercepted on the surface of the metal mesh.

[0018] The invention is further configured such that: there are two movable collars, which are respectively fixedly installed with movable plate one and movable plate two; one end of each of the two movable collars is rotatably connected to a fixing member via a bearing; both ends of the connecting rod are fixedly installed with snap-fit ​​blocks; the movable collar has a snap-fit ​​groove inside for engaging with the snap-fit ​​blocks; a spring is fixedly installed on the top of movable plate one and fixedly connected to the bottom of the fixed top plate; the top of movable plate one has a positioning support rod one fixedly connected to the fixing member and extending through to the top of the fixed top plate; and the fixed top plate has a sliding hole inside for engaging with the positioning support rod one.

[0019] Using the above technical solution, the movable collar, through the locking block and locking groove, helps the first and second movable plates move smoothly longitudinally on the surface of the connecting rod. Simultaneously, the rotation of the connecting rod still drives the first and second movable plates to rotate, thus achieving the desired effect. The spring installed between the first movable plate and the fixed top plate helps the first movable plate move longitudinally according to the water flow rate. When the water flow entering the water-conducting housing through the inlet pipe is small, the spring extends, and the position of the first movable plate is closer to the middle plate. When the water flow is large, the spring contracts, and the position of the first movable plate is closer to the fixed top plate. Simultaneously, the rotation of the connecting rod synchronously drives the fixed top plate and the first movable plate to rotate, preventing the spring from becoming twisted and unusable. Furthermore, during the longitudinal movement of the first movable plate, the fixing component synchronously drives the first positioning rod to move longitudinally. The bearing between the movable collar and the fixing component prevents the rotation of the movable collar from affecting the first positioning rod. The first positioning rod, in conjunction with the sliding hole, guides the movement of the first movable plate.

[0020] The present invention is further configured such that: a bevel gear one is fixedly sleeved on the top of the screw, a bevel gear two meshes with the surface of the bevel gear one, a rod body rotatably connected to the inside of the bevel gear two is fixedly sleeved inside the control housing, a gear is fixedly sleeved on one end of the rod body, a rack meshes with the surface of the gear, a connecting rod one fixedly installed on the rear side of the rack and fixedly connected to the top of the positioning support rod one, a threaded block is threadedly connected to the bottom surface of the screw, a connecting rod two is fixedly installed on one side of the threaded block, and positioning support rod two fixedly connected to the bottom of the fixing component is fixedly installed at both ends of the top of the connecting rod two.

[0021] Using the above technical solution, the movement of the positioning support rod one will drive the connecting rod one and the rack to move longitudinally at the same time. The rack will cause the longitudinal movement to mesh with the gear, thereby driving the gear to rotate. The gear will drive the rod body and the bevel gear two to rotate. At this time, the bevel gear one meshing with the bevel gear two will be transmitted and drive the screw to rotate. During the rotation of the screw, the threaded block and the connecting rod two will move longitudinally. The connecting rod two will drive the positioning support rod two and the moving plate two to move. Through a series of meshing transmissions, the final movement of the moving plate two is opposite to that of the moving plate one.

[0022] The present invention is further configured such that: a controller is fixedly installed on the surface of the motor end, an inlet flow meter is installed on the inlet pipe, and an outlet flow meter is installed on the outlet pipe.

[0023] Using the above technical solution, the controller controls the motor to open and close, which is the existing conventional structure. The inlet flow meter will detect the water flow in the inlet pipe, and the outlet flow meter will detect the water flow in the outlet pipe.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. In the use of the circulating pump, the water connected by the inlet pipe is transferred sequentially through the inlet pipe, water passage housing, water passage pipe one, water passage pipe two, and outlet pipe by the operation of the motor end, and discharged from the outlet pipe to the required place, realizing the use of the circulating pump. The impeller one will rotate due to the flow of water, and drive the scraper to move. The scraper contacts the inner wall of the water passage housing through the convex scraper, thereby descaling and cleaning the part of the water passage housing between the middle plate and the fixed top plate, and at the same time helping to remove dirt and impurities intercepted on the surface of the metal mesh. This setting helps to clean the water entering the pump housing, and at the same time avoids the long-term circulation of hot water, which may affect the pump impeller inside the pump housing due to scale.

[0026] 2. During water transfer, when the water reaches between the middle plate and the first transfer plate, the first transfer plate contracts and expands in accordance with the water flow, and transmits this movement trend to the second transfer plate. This causes the second transfer plate to apply pressure to the water about to enter the second water pipe, making it easier for the water to reach the required position more quickly. At the same time, the first transfer plate can also accelerate the flow of water to the pump casing through the movement and expansion of the spring. This control device facilitates the use of the circulation pump even when the water flow is small, while reducing the waiting costs of water slowly filling the pump casing and slowly reaching the destination, and making it easier to use the water quickly.

A control structure 3 is located at the bottom of the pump casing 103. A pipe structure 2 connects the pump casing 103 and the control structure 3. The control structure 3 includes a housing assembly 301, which includes a water-passing housing 3011 and a control housing 3012. A scraping assembly 302 is located inside the water-passing housing 3011. The scraping assembly 302 includes a middle plate 3021, which is rotatably connected to the water-passing housing 3011 via a waterproof bearing. During the use of the circulating pump, the operation of the motor end 101 causes water connected by the inlet pipe 201 to flow sequentially through the inlet pipe 201 and the water-passing housing 3012. 011, Water pipe 1 202, Water pipe 2 203 and Water outlet pipe 204 transmit water and discharge it to the required place from Water outlet pipe 204, realizing the use of this circulating pump. Impeller 1 3025 will rotate due to the flow of water and drive scraper 3027 to move. Scraper 3027 contacts the inner wall of water housing 3011 through convex scraper 3028, thereby descaling and cleaning the part of water housing 3011 between middle plate 3021 and fixed top plate 30210, and at the same time helping to remove dirt and impurities intercepted on the surface of metal mesh 30213. This setting helps to clean the water entering the pump housing 103, and at the same time avoids long-term transmission of circulating hot water, as scale will affect the pump wheel 108 inside the pump housing 103.

[0043] refer to Figure 1 , Figure 2 The motor end 101 and the shaft 105 are fixedly connected to each other. A fixed plate 106 is fixedly installed at the bottom of the shaft 105.

The fixed plate 106 and the pump wheel 108 are both located inside the pump casing 103. The operation of the motor end 101 will drive the shaft 105, the fixed plate 106, the ring 107 and the pump wheel 108 to rotate, so that the ring 107 and the pump wheel 108 will introduce water into the pump casing 103 through the centrifugal force generated, so as to realize the circulation of the circulating pump.

The other side of the water-passing housing 3011 is connected to a first water-passing pipe 202 and an outlet pipe 204. One end of the first water-passing pipe 202 is connected to the inlet of the pump housing 103. The outlet of the pump housing 103 is connected to a second water-passing pipe 203, which is connected to one side of the water-passing housing 3011. External water enters the interior of the water-passing housing 3011 through the inlet pipe 201, then enters the interior of the pump housing 103 through the first water-passing pipe 202, and then re-enters the water-passing housing 3011 through the second water-passing pipe 203, and is then discharged to the required location through the outlet pipe 204.

[0046] refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 A connecting rod 3022 is fixedly installed inside the middle layer plate 3021. The top of the middle layer plate 3021 is provided with an impeller 3025, a sliding plate 3023, and a fixed top layer plate 30210, which are sleeved on the surface of the connecting rod 3022. The bottom of the middle layer plate 3021 is provided with an impeller 3026 and a sliding plate 3024, which are sleeved on the surface of the connecting rod 3022. Both impeller 3025 and impeller 3026 are fixedly sleeved with the connecting rod 3022. The fixed top layer plate 30210 is fixedly connected with the connecting rod 3022. The fixed top plate 30210 and the water-conducting shell 3011 are rotatably connected to each other via waterproof bearings. Both the middle plate 3021 and the fixed top plate 30210 support the connecting rod 3022 and cooperate with its rotation. Impeller 1 3025 and impeller 2 3026 will rotate in the same direction due to the flow of water, which will then drive the connecting rod 3022, the middle plate 3021, and the fixed top plate 30210 to rotate. The waterproof bearings cooperate with the fixed top plate 30210 to support it and facilitate its smooth rotation.

[0047] refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 A scraper 3027 is embedded in one side of the middle layer plate 3021. The top of the scraper 3027 is fixedly connected to the top fixed layer plate 30210. A raised scraper strip 3028 is fixedly installed on one side of the scraper 3027. A slot 3029 for accommodating the scraper 3027 is provided on one side of both the middle layer plate 3021 and the first moving plate 3023. A scale discharge pipe 30211 located at the top of the middle layer plate 3021 is connected to the surface of the water inlet pipe 2011. A control valve 30212 is installed on the scale discharge pipe 30211. A metal mesh 30213 is embedded in one side of the water inlet pipe 201. The scraper 3027 moves with the movement of the middle layer plate 3021 and the top fixed layer plate 30210, and is connected to the first moving plate 30210 through the slot 3029. A sliding snap-fit ​​is formed between the three layers. During the rotation of the scraper 3027, the convex scraper 3028 contacts the inner wall of the water-passing housing 3011, thereby descaling and cleaning the part of the water-passing housing 3011 between the middle layer plate 3021 and the fixed top layer plate 30210. The water containing dirt that has been cleaned will be discharged through the scale discharge pipe 30211. The control valve 30212 is opened and closed in conjunction with the scale discharge pipe 30211. The metal mesh 30213 will push the dirt on the surface into the pump housing 103. At the same time, it can also intercept some impurities in the water before it enters the pump housing 103. During the scraping process of the convex scraper, it also contacts the metal mesh 30213, which can help remove the dirt and impurities intercepted on the surface of the metal mesh 30213.

[0048] Brief description of usage: In the use of the circulating pump, the inlet pipe 201 is connected to the external water supply equipment. The controller 4 controls the motor end 101 to open and close. This is the existing conventional structure. The operation of the motor end 101 drives the shaft 105, the fixed plate 106, the ring 107, and the pump wheel 108 to rotate. This causes the ring 107 and the pump wheel 108 to use centrifugal force to transfer the water connected to the inlet pipe 201 through the inlet pipe 201, the water passage housing 3011, the first water passage pipe 202, the second water passage pipe 203, and the outlet pipe 204, and then discharge it from the outlet pipe 204 to the desired location, thus achieving... In the operation of this circulating pump, when water preferentially enters the water-conducting housing 3011 through the inlet pipe 201, the water is located between the middle plate 3021 and the first moving plate 3023. The impeller 3025 rotates due to the water flow, driving the connecting rod 3022, the middle plate 3021, and the fixed top plate 30210 to rotate. A waterproof bearing supports the fixed top plate 30210 and facilitates its smooth rotation. Furthermore, both the middle plate 3021 and the fixed top plate 30210 support the connecting rod 3022 and facilitate its rotation. The scraper 3027 follows the middle plate 3021 and... The fixed top plate 30210 moves, and a sliding engagement is formed between the slot 3029 and the moving plate 3023. During the rotation of the scraper 3027, the convex scraper 3028 contacts the inner wall of the water-passing housing 3011, thereby descaling the portion of the water-passing housing 3011 between the middle plate 3021 and the fixed top plate 30210. The cleaned water containing dirt is then discharged through the scale discharge pipe 30211. The control valve 30212, in conjunction with the scale discharge pipe 30211, opens and closes. The metal mesh 30213 draws the surface dirt into the pump housing 103, and simultaneously... The water entering the pump housing 103 is partially impurities intercepted by the moving convex scraper blades, which also come into contact with the metal mesh 30213. This helps remove the dirt and impurities intercepted on the surface of the metal mesh 30213, causing the scraper rod 3027 to contact the inner wall of the water passage housing 3011. This setup helps to clean the water entering the pump housing 103, while preventing the long-term circulation of hot water from affecting the pump impeller 108 inside the pump housing 103 due to scale buildup. The water entering the pump housing 103 then flows back into the water passage housing 3011 through the water passage pipe 203, and is then discharged to the desired location through the outlet pipe 204.

[0049] Example 2:

[0050] refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7A circulating pump control device and control system includes a pump body structure 1, a telescopic component 303 provided inside a scraping assembly 302, the telescopic component 303 including a movable collar 3031, and a pressure supply drive component 304 extending through to the inside of a control housing 3012 at the top of the telescopic component 303. The pressure supply drive component 304 includes a screw 3041, which is rotatably connected to the inside of the control housing 3012 via bearings. During water transfer, when water reaches between the middle plate 3021 and the first moving plate 3023, the first moving plate 3023 coordinates with the water flow... The pump expands and contracts, and transmits this movement to the second sliding plate 3024, which pressurizes the water about to enter the second water pipe 203, making it easier for the water to reach the desired position more quickly. At the same time, the sliding plate 3023, through the movement and extension of the spring 3034, can also accelerate the flow of water to the pump casing 103. This control device facilitates the use of the circulation pump even when the water flow is small, while reducing the waiting costs of the water slowly filling the pump casing 103 and slowly reaching the destination, making it easier to circulate the water quickly.

[0051] refer to Figure 5 , Figure 6There are two movable collars 3031, which are fixedly installed to the first movable plate 3023 and the second movable plate 3024 respectively. One end of each movable collar 3031 is rotatably connected to a fixing member 30411 via a bearing. Both ends of the connecting rod 3022 are fixedly installed with locking blocks 3032. The movable collar 3031 has a locking groove 3033 inside for engaging with the locking blocks 3032. A spring 3 is fixedly installed on the top of the first movable plate 3023 and fixedly connected to the bottom of the fixed top plate 30210. 034, the top of the first moving plate 3023 is provided with a positioning support rod 3035 that is fixedly connected to the fixing member 30411 and extends through to the top of the fixed top plate 30210. The interior of the fixed top plate 30210 is provided with a sliding hole 3036 for sliding with the positioning support rod 3035. The moving collar 3031 will assist the first moving plate 3023 and the second moving plate 3024 to move smoothly longitudinally on the surface of the connecting rod 3022 through the locking block 3032 and the locking groove 3033. At the same time, it can also ensure that the rotation of the connecting rod 3022 still drives the first moving plate 3023. 3. The rotating plate 3024 achieves the desired effect. The spring 3034 between the moving plate 3023 and the fixed top plate 30210 helps the moving plate 3023 move longitudinally according to the water flow rate. When the water flow entering the water-conducting housing 3011 through the inlet pipe 201 is small, the spring 3034 extends, and the moving plate 3023 is closer to the middle plate 3021. When the water flow is large, the spring 3034 retracts, and the moving plate 3023 is closer to the fixed top plate 30210. At the same time, the connecting rod 302... The rotation of 2 will synchronously drive the fixed top plate 30210 and the moving plate 3023 to rotate, preventing the spring 3034 from becoming twisted and unusable. During the longitudinal movement of the moving plate 3023, the positioning support rod 3035 will be driven to move longitudinally through the fixing member 30411. The bearing between the moving collar 3031 and the fixing member 30411 prevents the rotation of the moving collar 3031 from affecting the positioning support rod 3035. The positioning support rod 3035 and the sliding hole 3036 cooperate with the movement of the moving plate 3023 to guide it.

[0052] refer to Figure 3 , Figure 4 , Figure 5 , Figure 7A bevel gear 3042 is fixedly sleeved on the top of the screw 3041. A bevel gear 3043 meshes with the surface of the bevel gear 3042. A rod 3045, rotatably connected to the inside of the control housing 3012, is fixedly sleeved inside the bevel gear 3043. A gear 3044 is fixedly sleeved on one end of the rod 3045. A rack 3046 meshes with the surface of the gear 3044. A connecting rod 3047, fixedly connected to the top of the positioning support rod 3035, is fixedly installed on the rear side of the rack 3046. A threaded block 3048 is threadedly connected to the bottom surface of the screw 3041. A connecting rod 3049 is fixedly installed on one side of the threaded block 3048. A positioning support rod 30410, fixedly connected to the bottom of the fixing part 30411, is fixedly installed at both ends of the top of the connecting rod 3049. The movement of the support rod 3035 will drive the connecting rod 3047 and the rack 3046 to move longitudinally simultaneously. The rack 3046 will mesh with the gear 3044, causing the gear 3044 to rotate. The gear 3044 will then drive the rod 3045 and the bevel gear 3043 to rotate. At this time, the bevel gear 3042 meshing with the bevel gear 3043 will be transmitted and drive the screw 3041 to rotate. During the rotation of the screw 3041, the threaded block 3048 and the connecting rod 3049 will move longitudinally. The connecting rod 3049 will drive the positioning support rod 30410 and the moving plate 3024 to move. Through a series of meshing transmissions, the final direction of movement of the moving plate 3024 is opposite to that of the moving plate 3023.

[0053] refer to Figure 1 , Figure 2 A controller 4 is fixedly installed on the surface of the motor end 101, an inlet flow meter 5 is installed on the inlet pipe 201, and an outlet flow meter 6 is installed on the outlet pipe 204. The controller 4 controls the motor end 101 to open and close. This is the existing conventional structure. The inlet flow meter 5 will detect the water flow of the inlet pipe 201, and the outlet flow meter 6 will detect the water flow of the outlet pipe 204.

[0054] Brief description of usage: During water transfer, when water reaches between the middle plate 3021 and the first moving plate 3023, the spring 3034 installed between the first moving plate 3023 and the fixed top plate 30210 helps the first moving plate 3023 move longitudinally according to the water flow rate. When the water flow entering the water-conducting housing 3011 through the inlet pipe 201 is small, the spring 3034 extends, and the position of the first moving plate 3023 is closer to the middle plate 3021. When the water flow is large, the spring 3034 retracts, and the position of the first moving plate 3023 is closer to the fixed top plate 30210. At the same time, the rotation of the connecting rod 3022 will synchronously drive the fixed top plate 30210 and the first moving plate 3023 to rotate, without... In the event of spring 3034 becoming twisted and unusable, and during the longitudinal movement of the first sliding plate 3023, the moving collar 3031, through the locking block 3032 and the locking groove 3033, facilitates the smooth longitudinal movement of the first sliding plate 3023 and the second sliding plate 3024 on the surface of the connecting rod 3022. Simultaneously, the rotation of the connecting rod 3022 still drives the first sliding plate 3023 and the second sliding plate 3024 to rotate, thus achieving the effect of synchronously driving the positioning support rod 3035 longitudinally via the fixing member 30411. Furthermore, the bearing between the moving collar 3031 and the fixing member 30411 prevents the rotation of the moving collar 3031 from affecting the positioning support rod 3035. The sliding plate 3023 moves in conjunction with the sliding hole 3036 to guide the movement of the sliding plate 3023. The sliding plate 3023 expands and contracts according to the water flow. Simultaneously, the movement of the positioning support rod 3035 drives the connecting rod 3047 and the rack 3046 to move longitudinally. The rack 3046's longitudinal movement causes it to mesh with the gear 3044, thus driving the gear 3044 to rotate. The gear 3044 then drives the rod 3045 and the bevel gear 3043 to rotate. At this time, the bevel gear 3042, which meshes with the bevel gear 3043, is transmitted and drives the screw 3041 to rotate. During the rotation of the screw 3041, the threaded block 3048 and the connecting rod 3047 are moved together. The longitudinal movement of 49 causes the connecting rod 3049 to drive the positioning support rod 30410 and the moving plate 3024 to move. Through a series of meshing transmissions, the final movement of the moving plate 3024 is opposite to that of the moving plate 3023, so that the moving plate 3024 applies pressure to the water that is about to enter the water pipe 203, making it easier for the water to reach the required position more quickly. At the same time, the moving plate 3023 can also accelerate the flow of water to the pump casing 103 through the extension of the spring 3034. This control device makes it easier to use the circulation pump when the water flow is small, reduces the waiting cost of the water slowly filling the pump casing 103 and slowly reaching the destination, and makes it easier to use the water quickly.
