Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Many 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 different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0021] Example 1: Refer to Figures 1-6 This is the first embodiment of the present invention, which provides a water supply and drainage pipeline end treatment device.

[0022] Specifically, the water delivery assembly 10 includes a support platform 11, a cam member 12 disposed on the end face of the support platform 11, a guide pipe 13 disposed on the end face of the support platform 11, the guide pipe 13 includes a buffer pipe 131, a one-way valve is provided inside the guide pipe 13 and the one-way valve is distributed on the upper and lower sides of the buffer pipe 131, a piston 14 disposed inside the buffer pipe 131, a first hinge rod 15 and a second hinge rod 16 disposed between the piston 14 and the cam member 12, and a jet pipe 17 communicating with the guide pipe 13. The filter assembly 20 includes a mixing tank 21 located below the spray pipe 17, a support frame 22 located at one end of the mixing tank 21, and a driven shaft 23 passing through the support frame 22. An intermittent component 30 is provided between the water supply component 10 and the filter component 20.

[0023] A guide tube 13 is installed at the upper end of the support platform 11. A buffer tube 131 is connected to the outer wall of the guide tube 13 facing the cam component 12. A one-way valve is fixedly connected to the inner wall of the guide tube 13. The function of the one-way valve is to allow liquid to flow from bottom to top along the guide tube 13 when liquid flows from bottom to top, and to prevent backflow. A simple one-way valve with a ball and spring combination can be used here, which will not be described in detail here. At the same time, a piston 14 is slidably installed inside the buffer tube 131. A first hinge rod 15 is connected to the outer wall of the piston 14 near the cam component 12. At the same time, a second hinge rod 16 is connected to the other end of the first hinge rod 15. Both the first hinge rod 15 and the second hinge rod 16 are provided with rings at the connection point. The two rings are interlocked. At the same time, in order to prevent the piston 14 from sliding and blocking, the first hinge rod 15 and the piston 14 are connected by a ball joint.

[0024] In this design, the main function of the cam 12 is to drive the piston 14 to slide back and forth inside the buffer tube 131 when the cam 12 rotates. The second hinge rod 16 is rotatably mounted on the outer wall of the cam 12. When the cam 12 rotates, it drives the piston 14 to slide back and forth inside the buffer tube 131. Specifically, a servo motor is installed inside the support platform 11, and the drive shaft of the servo motor is connected to the cam 12. When the cam 12 rotates, it drives the piston 14 to move back and forth inside the buffer tube 131. Furthermore, the one-way valves are arranged inside the guide pipe 13 and distributed on the upper and lower sides of the buffer pipe 131. When the piston 14 moves towards the one-way valve, the one-way valve at the lower end of the buffer pipe 131 closes and the one-way valve at the upper end of the buffer pipe 131 opens, allowing the water to flow upward. Subsequently, the piston 14 moves away from the one-way valve, the internal air pressure decreases, the one-way valve at the lower end of the buffer pipe 131 opens, and the water flows into the buffer tank 131, reciprocating to achieve the goal of the water flowing into the guide pipe 13 along the lower end of the guide pipe 13 and moving upward along the guide pipe 13.

[0025] Meanwhile, a spray pipe 17 is connected to the upper end of the guide pipe 13. The spray pipe 17 is located above the filter assembly 20, and each spray pipe 17 has a spray port below it. That is, there are through holes in a straight line along the outer wall of the spray pipe 17, and the through holes connect the inside and outside of the spray pipe 17. When the liquid is transported into the spray pipe 17 through the guide pipe 13, the inside of the spray pipe 17 is filled with liquid. When the piston 14 moves toward the one-way valve, it squeezes the liquid inside, and the liquid is sprayed out along the through holes.

[0026] The mixing tank 21 of the filter assembly 20 is as follows Figure 1 As shown, a cylindrical structure has multiple channels arrayed on its surface, and a filter screen is wrapped around the inner wall of the mixing tank 21. One end of the mixing tank 21 is connected to a drainage pipe. After the rainwater inside the drainage pipe enters the mixing tank 21, the filter screen filters out impurities such as silt and sand that cannot be removed from the mixing tank 21. At the same time, when the mixing tank 21 rotates, it will be washed by the sprayed liquid when it passes under the spray pipe 17, thus preventing surface blockage.

[0027] The main function of the water conveying assembly 10 is to transport the filtered rainwater into the spray pipe 17, and then clean the surface of the mixing tank 21. At the same time, an intermittent assembly 30 is set between the water conveying assembly 10 and the filter assembly 20. The main function of the intermittent assembly 30 is to make the rotation speed of the mixing tank 21 and the cam 12 different, and to transmit the power of the cam 12 to the mixing tank 21 through the intermittent assembly 30. Using the same power source can save the installation space of other power sources. At the same time, by reducing the speed through the intermittent assembly 30, the mixing tank 21 is prevented from moving too fast, which would result in excessive centrifugal force and cause the internal sludge to be thrown away.

[0028] In summary, one end of the mixing tank 21 is connected to a drainage pipe, and rainwater is discharged into the mixing tank 21 through the drainage pipe. Then, the filter screen on the inner wall of the mixing tank 21 filters out mud, sand, silt, etc. from the rainwater. Subsequently, the rainwater passes through the mixing tank 21. It should be noted that the guide pipe 13 is connected to the filtered rainwater, and the cam component 12 is rotated by the servo motor, which then continuously transports the rainwater into the spray pipe 17, and then rinses the mixing tank 21.

[0029] Example 2: Refer to Figures 1-6 This is the second embodiment of the present invention, which differs from the previous embodiment.

[0030] Specifically, the mixing tank 21 shown is equipped with a conveying pipe 24 inside.

[0031] Among them, such as Figure 2 As shown, a conveying pipe 24 is connected to the outside of the mixing tank 21. The conveying pipe 24 is located below the spray pipe 17. The advantage of this design is that when the mixing tank 21 rotates, it will carry some silt, sand and other impurities. The spray pipe 17 can wash away the silt, sand and other impurities attached to the filter screen and then drop them into the conveying pipe 24. At the same time, the washed rainwater is transported along the conveying pipe 24 to other places for treatment, which effectively avoids the mixing tank 21 from clogging. At the same time, it can also separate impurities.

[0032] Preferably, one end of the injection pipe 17 branches into two guide pipes 13.

[0033] like Figure 3 As shown, the spray pipe 17 branches into guide pipes 13 on both sides from one end near the water conveying component 10. The advantage of this design is that rainwater is transported synchronously through the two guide pipes 13, ensuring the water pressure inside the spray pipe 17 and improving the rinsing efficiency of the mixing tank 21.

[0034] Furthermore, the cam component 12 includes a first disk 121, and a first limiting rod 1211 is provided at a non-circular position on the end face of the first disk 121; A driven rod 122 is provided on the end face of the first disk 121. The driven rod 122 includes a first slide groove 1221 for sliding of the first limiting rod 1211. A first hinge rod 15 is connected to the outer wall of the driven rod 122.

[0035] The cam component 12 includes a first disk 121, which is rotatably mounted on the upper surface of the support platform 11. A servo motor is installed inside the support platform 11 and connected to the first disk 121 to drive its rotation. A first limiting rod 1211 is fixedly mounted on the upper surface of the first disk 121. The first limiting rod 1211 is a cylindrical structure and its installation position is not at the center of the first disk 121. A driven rod 122 is sleeved on the outer surface of the first limiting rod 1211. When the first disc 121 rotates, the first limiting rod 1211 slides along the inner wall of the first groove 1221 inside the driven rod 122, thereby driving the driven rod 122 to rotate left and right. At the same time, the first hinge rod 15 is connected to the outer wall of the driven rod 122. When the driven rod 122 rotates, it pushes the first hinge rod 15, thereby realizing the reciprocating motion of the piston 14 along the inside of the buffer tube 131. Figure 3 As shown, both sides of the driven rod 122 are connected to the first connecting rod 15. The advantage of this design is that when the driven rod 122 turns to one of the buffer tubes 131, the rainwater is squeezed upwards inside the buffer tube 131. At the same time, the rainwater is stored inside the other buffer tube 131. When the driven rod 122 rotates again, during the process of the driven rod 122 turning to the buffer tube 131, the rainwater inside the buffer tube 131 begins to push into the spray pipe 17. This achieves continuous rainwater replenishment from the two buffer tubes 131 to the spray pipe 17, ensuring the water pressure inside the spray pipe 17 and ensuring the washing effect.

[0036] Preferably, the end face of the support platform 11 is provided with a first fixed shaft 111, and the driven rod 122 is sleeved on the outer wall of the first fixed shaft 111.

[0037] A first fixed shaft 111 is fixedly installed on the upper surface of the support platform 11. The end of the driven rod 122 away from the first disc 121 is sleeved on the outer wall of the first fixed shaft 111 to ensure that the rotation point of the driven rod 122 remains unchanged and to ensure stable transportation of the conveying assembly 10.

[0038] Example 3: Reference Figures 1-6 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0039] Preferably, the outer wall of the first disk 121 is arrayed with a first cylinder 1212, and the support platform 11 includes a first support frame 112; The intermittent component 30 includes a drive shaft 31 that passes through the first support frame 112, the outer wall of the drive shaft 31 is provided with a second cylinder 311, and the other end of the drive shaft 31 is connected to a second support frame 32.

[0040] The first cylinder 1212 is arranged in a circumferential array on the outer wall of the first disk 121. At the same time, a first support frame 112 is fixedly installed on the upper surface of the support platform 11. The drive shaft 31 passes through the first support frame 112. A second cylinder 311 is arranged in a circumferential array on the outer wall of the drive shaft 31 near the first disk 121. The first cylinder 1212 and the second cylinder 311 are staggered. When the first disk 121 rotates, the first cylinder 121 pushes the second cylinder 311, which in turn drives the drive shaft 31 to rotate.

[0041] The second support frame 32 is installed at one end of the drive shaft 31 near the mixing tank 21, and works with the first support frame 112 to support the drive shaft 31.

[0042] Preferably, the outer wall of the drive shaft 31 is provided with a bidirectional threaded groove 312, the outer wall of the drive shaft 31 is fitted with an arc-shaped plate 33, and the inner wall of the arc-shaped plate 33 is rotatably provided with a first slider that can slide along the inside of the bidirectional threaded groove 312. The outer wall of the driven shaft 23 is provided with a spiral groove 231 and a bell mouth 232, and the spiral groove 231 and the bell mouth 232 are connected. The intermittent assembly 30 includes a sleeve 34 fitted on the outer wall of the driven shaft 23, and a second slider 35 that can slide along the inside of the spiral groove 231 is rotatably provided on the outer wall of the sleeve 34. Sleeve 34 is connected to arc plate 33.

[0043] The drive shaft 31 has a bidirectional threaded groove 312 on the outer wall of the first support frame 112 near the filter assembly 20. The bidirectional threaded groove 312 is formed by two staggered helical grooves with opposite directions, and the two helical grooves are connected at both ends. Simultaneously, an arc-shaped plate 33 is fitted onto the outer wall of the drive shaft 31. A first slider is rotatably mounted on the inner wall of the arc-shaped plate 33. When the drive shaft 31 rotates, the arc-shaped plate 33 can slide along the surface of the drive shaft 31. The arc-shaped plate 33 has a structure exceeding a semicircle, allowing it to fit onto the surface of the drive shaft 31 and preventing it from detaching from the drive shaft 31. Simultaneously, the arc-shaped plate 33 slides along the upper surface of the second support frame 32, ensuring that the arc-shaped plate 33 moves back and forth along the surface of the drive shaft 31 when the drive shaft 31 rotates. The other end is fixedly connected to the sleeve 34, which is sleeved on the surface of the driven shaft 23. A second slider 35 is rotatably installed on the side of the sleeve 34 near the stirring 21. At the same time, a spiral groove 231 is provided on the outer wall of the driven shaft 23. A bell mouth 232 is connected to the end of the spiral groove 231 near the sleeve 34. The bell mouth 232 is an outwardly opening groove. When the arc plate 33 slides along the surface of the drive shaft 31, and the sleeve 34 is close to the driven shaft 23, the second slider 35 on the outer wall of the sleeve 34 slides along the inner wall of the bell mouth 232 into the spiral groove 231, and then drives the driven shaft 23 to rotate. The advantage of this design is that the sleeve 34 and the driven shaft 23 do not need to be in a specific position. The second slider 35 can be slid into the spiral groove 231 at any position.

[0044] Furthermore, the outer wall of the sleeve 34 is provided with a first notch 341 for the second slider 35 to rotate, and a first elastic element 36 is provided between the first notch 341 and the second slider 35. The second slider 35 includes a first arc surface 351.

[0045] The sleeve 34 has a first notch 341 on its outer wall near the mixing tank 21. The second slider 35 is an L-shaped structure, with one end rotatably mounted inside the first notch 341 and the other end having a first arc surface 351 on its outer wall. A first elastic element 36, a compression spring, is provided between the outer wall of the first notch 341 and the inner wall of the first notch 341. This design allows the second slider 35 to slide along the inner wall of the flared opening 232 into the spiral groove 231, subsequently driving the driven shaft 23 to rotate. When the sleeve 34 enters the bottom of the spiral groove 231, it begins to move towards the water conveying assembly 10. Then, the first arc surface 351 of the outer wall of the second slider 35 slides along the inner wall of the spiral groove 231, and the second slider 35 rotates. At the same time, it squeezes the first elastic element 36. Then, the sleeve 34 disengages from the driven shaft 23. When the sleeve 34 moves towards the mixing tank 21, the end of the second slider 35 near the first arc surface 351 abuts against the outer wall of the sleeve 34 to prevent the second slider 35 from rotating inward. Then, the second slider 35 enters the spiral groove 231 along the flared opening 232, thereby driving the driven shaft 23 to rotate. The sleeve 34 reciprocates, continuously pushing the driven shaft 23 to rotate.

[0046] Preferably, the number of turns of the bidirectional threaded groove 312 is different from the number of turns of the helical groove 231.

[0047] The bidirectional threaded groove 312 has more turns than the spiral groove 231. The advantage of this design is that when the drive shaft 31 rotates multiple times, the driven shaft 23 will only rotate once, which will not affect the conveying component 10 or the mixing tank 21.

[0048] Preferably, a third support frame 37 is provided on the outer wall of the driven shaft 23 near the intermittent assembly 30; The outer wall of the sleeve 34 is provided with a reflux plate 342.

[0049] Among them, a third support frame 37 is provided on the outer wall of the driven shaft 23 near the drive shaft 31 to support the driven shaft 23; at the same time, an L-shaped return plate 342 is fixedly installed at the lower end of the sleeve 34. The advantage of this design is that the return plate 342 can push some water back to the direction of the mixing tank 21 as the sleeve 34 moves back and forth, which can rinse the end of the mixing tank 21 near the water supply component 10 and prevent the filter screen of the mixing tank 21 near the water supply component 10 from becoming clogged. It should be noted that the first support frame 112 and the second support frame 32 support the drive shaft 31 and can be connected by bearings to reduce friction.

[0050] In summary, after the servo motor starts, it drives the first disc 121 on the end face of the support platform 11 in the water delivery assembly 10 to rotate. The first limiting rod 1211 at the non-center of the first disc 121 slides along the first sliding groove 1221 of the driven rod 122, causing the driven rod 122 to swing left and right around the first fixed axis 111 of the support platform 11. Then, through the cooperation of the first hinge rod 15 and the second hinge rod 16, the piston 14 in the buffer tube 131 is pushed to slide back and forth. Since the one-way valves in the guide tube 13 are distributed on the upper and lower sides of the buffer tube 131, when the piston 14 moves towards the one-way valve, the one-way valve at the lower end of the buffer tube 131 closes and the one-way valve at the upper end opens, and the water flow is squeezed upward. When the piston 14 moves away from the one-way valve, the air pressure inside the buffer tube 131 decreases, the one-way valve at the lower end opens, and the filtered rainwater enters the buffer tube 131. This process is repeated to achieve continuous delivery of rainwater to the spray pipe 17. Two guide pipes 13 branch off from one end of the spray pipe 17, which simultaneously replenish rainwater into the spray pipe 17 to ensure stable water pressure inside the spray pipe 17. The rainwater is evenly sprayed out through the through holes on the outer wall of the spray pipe 17 to rinse the surface of the mixing tank 21 below.

[0051] Simultaneously, water is transferred from the water supply assembly 10 to the filter assembly 20 via the intermittent component 30: when the first cylinder 1212 on the outer wall of the first disc 121 rotates, it alternately pushes the second cylinder 311 on the outer wall of the drive shaft 31, causing the drive shaft 31 to rotate around the first support frame 112 and the second support frame 32; the bidirectional threaded groove 312 on the outer wall of the drive shaft 31 causes the arc plate 33 sleeved on it to slide back and forth, and the sleeve 34 connected to the arc plate 33 moves synchronously with it. Under the action of the first elastic element 36, the second slider 35 on the outer wall of the sleeve 34 slides into the spiral groove 231 along the flared mouth 232 of the driven shaft 23, thereby driving the driven shaft 23 to rotate, and finally driving the stirring tank 21 fixedly connected to the outer wall of the driven shaft 23 to rotate. During the rotation of the mixing tank 21, the filter screen on its inner wall filters out impurities such as mud and silt from the rainwater discharged through the drainage pipe. Rainwater sprayed from the spray pipe 17 washes the surface of the mixing tank 21, preventing the filter screen from clogging. The washed-off impurities, along with the wash water, enter the conveying pipe 24 inside the mixing tank 21 and are transported to a designated location for processing. Simultaneously, the return plate 342 on the outer wall of the sleeve 34 reciprocates with the sleeve 34, pushing some rainwater back towards the mixing tank 21 to assist in rinsing the end of the mixing tank 21 near the water supply component 10, further preventing clogging. Furthermore, the bidirectional threaded groove 312 and the spiral groove 231 have different numbers of turns, creating a speed difference between the drive shaft 31 and the driven shaft 23. This prevents the mixing tank 21 from rotating too fast, generating excessive centrifugal force that could cause impurities to fly off, ensuring stable operation of the device.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
