Description

Technical Field

[0001] This application relates to the field of urban drainage technology, and in particular to a smart city stormwater and sewage pipe separation system. Background Technology

[0002] Urban drainage is a drainage system that collects, transports, treats, and discharges urban sewage and rainwater, playing an important role in urban flood control.

[0003] In related technologies, to meet drainage needs, most municipal drainage systems adopt a diversion system with high drainage efficiency. The intricate drainage pipes can effectively enhance the connectivity of municipal drainage and share the urban drainage pressure. This is a drainage method widely used in smart cities.

[0004] Regarding the aforementioned technologies, the inventors discovered that during drainage, rainwater and sewage wash away some impurities as they enter the drainage pipes, causing these impurities to enter the drainage system together. In a separate drainage system, due to the large number of pipes, if some parts are blocked by impurities, it can lead to blockage or even paralysis of the entire drainage system, thus requiring improvement. Summary of the Invention

[0005] In order to separate impurities from rainwater and sewage, reduce the probability of blockage in the diversion system, and maintain the normal operation of the drainage system, this application provides a smart city rainwater and sewage pipeline diversion system.

[0006] The smart city stormwater and sewage pipeline separation system provided in this application adopts the following technical solution:

[0007] A smart city stormwater and sewage pipe separation system includes a main shaft, in which a primary filter screen is installed. A connecting pipe is connected to the side wall of the main shaft, and the end of the connecting pipe opposite to the main shaft is connected to a debris removal shaft. Impurities on the surface of the primary filter screen enter the debris removal shaft through the connecting pipe. A filter plate is installed in the debris removal shaft, and the filter plate is used to drain the moisture carried by the impurities entering the debris removal shaft.

[0008] By adopting the above technical solution, when the drainage system is in operation, rainwater or sewage discharged into the system through the main shaft will pass through the primary filter screen, thus leaving impurities in the water on the surface of the primary filter screen. Then, it will enter the impurity removal shaft through the connecting pipe. The impurities entering the impurity removal shaft will fall onto the surface of the filter plate. After the filter plate further drains the water, the impurities are separated from the liquid. The separated impurities are collected in the impurity removal shaft for unified cleaning. This effectively improves the problem of blockage in the main shaft due to excessive impurities in the water, which can lead to blockage or even paralysis of the entire drainage system. It maintains the normal operation of the drainage system and has high practicality.

[0009] Preferably, the filter plate surface is recessed towards the center to form a drainage cavity, and a cleaning port is provided through the filter plate on the side away from the connecting pipe along the thickness direction. The cleaning port is connected to a drain pipe. The filter plate is provided with a dirt removal component, which is used to transport impurities in the drainage cavity into the drain pipe. The end of the drain pipe away from the filter plate passes through the dirt removal well and is connected to a dirt removal box.

[0010] By adopting the above technical solution, the surface of the filter plate is concave towards the center, thus forming a conical structure. Under the inclined structure inside the drainage chamber, it is easier for water to drain out. After the water drains out, the impurity removal component can move the impurities in the drainage chamber. When the impurities move to the cleaning port, they lose the contact with the filter plate and enter the impurity removal box through the drain pipe, waiting for unified treatment. This application can increase the impurity handling capacity of the impurity removal channel by setting the impurity removal component, improve the problem of the filter plate being blocked due to excessive impurities on its surface, and thus help to expand the impurity capacity that the impurity removal channel can bear, extend the cleaning cycle of the impurity removal channel, and reduce the workload.

[0011] Preferably, the impurity removal component includes a driving component, a connecting shaft, a first baffle, and a second baffle. The driving component is connected to the bottom wall of the filter plate, and the connecting shaft is disposed in the draining cavity. The connecting shaft is vertically arranged, and the output end of the driving component passes through the filter plate and is connected to the connecting shaft. The driving component drives the connecting shaft to rotate. The first baffle and the second baffle are both connected to the peripheral wall of the connecting shaft and abut against the inner wall of the draining cavity. The first baffle and the second baffle are used to prevent impurities in the draining cavity from entering the cleaning port.

[0012] By adopting the above technical solution, when impurities enter the draining chamber, the cleaning port is separated from the draining chamber by the first and second baffles, allowing the impurities to be fully drained within the draining chamber. After the water has drained, the driving component will drive the connecting shaft and the first and second baffles to rotate. The first baffle will push the impurities in the draining chamber to rotate. When the rotation coincides with the cleaning port, the impurities will enter the impurity removal box through the drain pipe, thus completing the cleaning of the impurities. This allows the filter plate to restore its load-bearing capacity and perform more impurity draining work, which has high convenience and practicality.

[0013] Preferably, the side wall of the cleaning well is connected to a return pipe, and the end of the return pipe away from the cleaning well is connected to the main well. The water accumulated in the cleaning well enters the main well through the return pipe.

[0014] By adopting the above technical solution, after the water mixed with impurities is drained by the filter plate, the accumulated water will be deposited at the bottom of the impurity removal well. When the height of the accumulated water rises to the height of the return pipe, the accumulated water will enter the main well through the return pipe to complete the discharge of the accumulated water. This allows the impurity removal well of this application to treat impurities and accumulated water at the same time, saving the time of cleaning the impurity removal well.

[0015] Preferably, the bottom wall of the impurity removal well is provided with a partition, and a rotating shaft is rotatably connected to the partition. The rotating shaft is hollow inside, and a scraper is connected to the peripheral wall of the rotating shaft extending out of the partition. A venting cavity is opened inside the scraper, and the venting cavity communicates with the hollow part inside the rotating shaft. An air outlet is opened on the side wall of the scraper, and a one-way valve is provided on the inner wall of the air outlet. A rotating component for driving the rotating shaft to rotate is provided on the bottom wall of the partition. A venting disc is sleeved on the peripheral wall of the rotating shaft below the partition. The venting disc is connected to an air pump. An air inlet is opened on the peripheral wall of the rotating shaft, and the air inlet communicates with the inside of the venting disc.

[0016] By adopting the above technical solution, the rotating component drives the rotating shaft and scraper to rotate, thereby scraping the sediment deposited on the bottom wall of the cleaning well channel, effectively improving the problem of solidification inside the cleaning well channel and maintaining the cleanliness of the cleaning well channel; at the same time, during the rotation of the scraper, the air pump introduces gas into the venting plate, the gas enters the venting chamber through the rotating shaft, and leaves the scraper through the air outlet, thereby forming bubbles. The generated bubbles carry the sediment scraped by the scraper to float to the surface of the water, making it easier for mud and other sediments to be discharged from the return pipe, thus improving the problem of sedimentation at the bottom of the cleaning well channel.

[0017] Preferably, a cleaning box is provided on the side wall of the sewage pipe, a cleaning roller is provided on the side wall of the cleaning box facing the return pipe, bristles are provided on the peripheral wall of the cleaning roller, and a driving component is provided inside the cleaning box. The driving component drives the cleaning roller to move toward the return pipe and cleans the inner wall of the return pipe.

[0018] By adopting the above technical solution, when the return pipe returns the accumulated water, some sludge will adhere to the inner wall of the return pipe, which will cause blockage of the return pipe after a long time. By driving the cleaning roller to move towards the return pipe through the drive component, the inner wall of the return pipe can be cleaned, thereby effectively reducing the probability of blockage of the return pipe and having high practicality.

[0019] Preferably, the drive assembly includes a drive motor, a drive sleeve, a drive screw, a splined shaft, and a splined tube. The drive tube passes through the cleaning box. The drive screw is threaded to the inner wall of the drive sleeve. The cleaning roller is sleeved on the peripheral wall of the cleaning box extending from the drive screw. The drive motor is located on the inner wall of the cleaning box. The output shaft of the drive motor is connected to the splined shaft. The splined tube is connected to the end of the drive screw near the drive motor. The end of the splined shaft away from the drive motor is inserted into the inner wall of the drive sleeve. The drive motor drives the drive screw to rotate through the transmission of the splined shaft and the splined tube.

[0020] By adopting the above technical solution, the drive motor drives the spline shaft to rotate, and then through the cooperation between the spline shaft and the spline tube, the spline tube is driven to rotate. The spline tube will further drive the drive screw to rotate. Due to the threaded cooperation between the drive screw and the drive sleeve, the drive screw will move towards or away from the return pipe during the rotation. During this process, the spline shaft and the spline tube gradually separate, so that the drive screw can drive the cleaning roller to move towards the return pipe. The cleaning roller can also clean the inner wall of the return pipe during rotation, thereby improving the cleaning power and reducing the probability of blockage in the return pipe.

[0021] Preferably, the spline tube end wall is provided with a plurality of oil passage holes, which are in communication with the inner cavity of the spline tube.

[0022] By adopting the above technical solution, the oil passage hole can be opened to lubricate the inside of the spline tube, thereby reducing the friction between the spline shaft and the spline tube, so that the drive assembly can drive the cleaning roller more smoothly.

[0023] Preferably, a secondary filter is provided below the primary filter, and the primary and secondary filters are arranged in parallel. A connecting rod is provided on the bottom wall of the primary filter, and the end of the connecting rod away from the primary filter is connected to the secondary filter. A sliding groove is provided on the inner wall of the main shaft for the connecting rod to be embedded and slide.

[0024] By adopting the above technical solution, setting up primary and secondary filters can perform graded filtration of rainwater or sewage, thereby screening out smaller impurities in rainwater or sewage, improving the filtration effect, and further reducing the probability of blockage in the main well channel; when there are impurities between the primary and secondary filters, the connecting rod can be slid by sliding the sliding groove to align the space between the primary and secondary filters with the connecting pipe, thereby discharging sewage.

[0025] Preferably, a drive pipe is provided on the side wall of the connecting pipe, the drive pipe is connected to the connecting pipe, a drive cylinder is provided inside the drive pipe, the base of the drive cylinder is hinged to the inner wall of the drive pipe, an opening and closing door is hinged at the connection between the drive pipe and the connecting pipe, the piston rod of the drive cylinder is hinged to the side wall of the opening and closing door, and the opening and closing door is used to block the main shaft and the cleaning shaft.

[0026] By adopting the above technical solution, an opening and closing gate is set up to block the main shaft and the impurity removal shaft. This effectively improves the problem of liquid directly rushing into the impurity removal shaft during large-volume drainage, causing the water level in the impurity removal shaft to rise and flow into the impurity removal box, resulting in impurities in the impurity removal box being backflowed into the impurity removal shaft. This solution has high practicality.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the drainage system is in operation, rainwater or sewage discharged into the system through the main shaft will pass through the primary filter screen, which will retain impurities on the surface of the primary filter screen. Then, it will enter the impurity removal shaft through the connecting pipe. The impurities entering the impurity removal shaft will fall onto the surface of the filter plate. The filter plate will further drain the water and separate the impurities from the liquid. The separated impurities will be collected in the impurity removal shaft for unified cleaning. This effectively improves the problem of blockage in the main shaft due to excessive impurities in the water, which can lead to blockage or even paralysis of the entire drainage system. It maintains the normal operation of the drainage system and has high practicality.

[0029] 2. The filter plate surface is concave towards the center, thus forming a conical structure. The inclined structure inside the drainage chamber facilitates water drainage. After drainage, the impurity removal component moves the impurities within the drainage chamber. When the impurities reach the cleaning port, they lose contact with the filter plate and enter the impurity removal box through the drain pipe for unified processing. This application, by setting the impurity removal component, increases the impurity handling capacity of the impurity removal channel, improving the problem of filter plate blockage due to excessive surface impurities, thus helping to expand the impurity capacity of the impurity removal channel, extending the cleaning cycle of the impurity removal channel, and reducing workload.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] Example 1:

[0039] Embodiment 1 of this application discloses a smart city stormwater and sewage pipeline separation system. (Refer to...) Figure 1 The system includes a main shaft 1, a cleaning shaft 3, and a connecting pipe 2 for connecting the main shaft 1 and the cleaning shaft 3. A primary filter 11 is installed in the main shaft 1 to filter impurities mixed in with rainwater or sewage entering the main shaft 1, thereby reducing the probability of blockage in the main shaft 1. The cleaning shaft 3 is arranged parallel to the main shaft 1. The connecting pipe 2 connects the main shaft 1 and the cleaning shaft 3. In this embodiment, the height of the connection between the connecting pipe 2 and the main shaft 1 is higher than the connection height between the connecting pipe 2 and the cleaning shaft 3. At the same time, the primary filter 11 is inclined and kept parallel to the connecting pipe 2. When impurities are retained on the surface of the primary filter 11, they will roll along the surface of the primary filter 11 under the influence of gravity and then enter the cleaning shaft 3 through the connecting pipe 2.

[0040] Reference Figure 1The impurity removal channel 3 is equipped with a filter plate 4, which has several filter holes. Impurities entering the impurity removal channel 3 will fall onto the surface of the filter plate 4, draining the water trapped in the impurities. After draining, it can be cleaned at the same time.

[0041] The implementation principle of the smart city rainwater and sewage pipeline diversion system in Embodiment 1 of this application is as follows: During the use of the drainage system, impurities in rainwater or sewage can be filtered out through the primary filter screen 11, and then the impurities are discharged into the impurity removal well 3 through the connecting pipe 2 for unified cleaning. This achieves the separation of liquid and impurities, effectively reducing the probability of drainage system blockage or even paralysis, and maintaining the normal operation of the drainage system.

[0042] Example 2:

[0043] The difference between Embodiment 2 and Embodiment 1 of this application is as follows:

[0044] Reference Figure 2 A secondary filter 12 is provided below the primary filter 11. The primary filter 11 and the secondary filter 12 are parallel to each other and are connected by a connecting rod 13 by welding. A sliding groove 14 is provided on the inner wall of the main shaft 1 in the vertical direction for the connecting rod 13 to be embedded and slide. In this embodiment, the mesh size of the secondary filter 12 is smaller than that of the primary filter 11, so that sewage or rainwater can be filtered more finely, which helps to further reduce the content of impurities in the liquid and further reduce the probability of drainage system blockage. When it is necessary to clean the impurities on the surface of the secondary filter 12, simply slide the connecting rod 13 along the sliding groove 14 so that the space above the secondary filter 12 is aligned with the connecting pipe 2, and the impurities can slide into the connecting pipe 2, thereby achieving the cleaning of impurities, which has high convenience.

[0045] Reference Figure 2 A drive pipe 21 is welded to the side wall of the connecting pipe. The drive pipe 21 is connected to the connecting pipe 2. An opening and closing door 23 is hinged to the inner wall of the connection between the drive pipe 21 and the connecting pipe 2. When the opening and closing door 23 rotates into the connecting pipe 2, it will block impurities or liquid from entering the impurity removal well 3. This effectively prevents a large amount of water from flowing into the impurity removal well 3 when the drainage volume is large, which would cause impurities in the impurity removal well 3 to be backflowed and cause blockage of the main well 1.

[0046] Reference Figure 2 A drive cylinder 22 is hinged to the top wall inside the drive tube 21. The base of the drive cylinder 22 is hinged to the inner wall of the drive tube 21. The piston rod of the drive cylinder 22 is set towards the opening and closing door 23 and is hinged to the side wall of the opening and closing door 23. When the drive cylinder 22 is started, it can push the opening and closing door 23 to rotate, thereby closing the connecting tube 2.

[0047] Reference Figure 2 and Figure 3 The filter plate 4 is cone-shaped, with its surface recessed towards the center to form a drainage cavity 41, allowing impurities to drain more quickly after entering the drainage cavity 41. A cleaning port 42 is provided on the side of the filter plate 4 away from the connecting pipe 2 along its thickness direction. The bottom wall of the cleaning port 42 is connected to a drain pipe 43 by welding. The end of the drain pipe 43 away from the filter plate 4 passes through the impurity removal well 3 and is connected to an impurity removal box 44. An impurity removal component 5 is provided on the filter plate 4 to transport the impurities into the cleaning port 42 after they have drained, thereby reducing the water content of the impurities entering the impurity removal box 44 and facilitating the cleaning of the impurities.

[0048] Reference Figure 2 and Figure 3 The impurity removal component 5 includes a drive unit 51, a connecting shaft 52, a first baffle 53, and a second baffle 54. In this embodiment, the drive unit 51 is a motor. The stator of the drive unit 51 is bolted to the bottom wall of the conical portion of the filter plate 4. The rotor of the drive unit 51 passes through the filter plate 4 and is connected to the connecting shaft 52 by a key. The connecting shaft 52 is disposed in the draining chamber 41 and is vertically arranged. The drive unit 51 can drive the connecting shaft 52 to rotate within the draining chamber 41. The first baffle 53 and the second baffle 54 are both welded to the peripheral wall of the connecting shaft 52 and are both vertically arranged. Both the bottom walls of the first baffle 53 and the second baffle 54 are inclined and abut against the inner wall of the draining cavity 41. In the initial state, the cleaning port 42 is located within the space enclosed by the first baffle 53 and the second baffle 54, which prevents impurities from entering the draining cavity 41 and falling further into the cleaning port 42. After the draining is completed, the drive component 51 will drive the connecting shaft 52, the first baffle 53 and the second baffle 54 to rotate. The first baffle 53 pushes the impurities into the cleaning port 42, completing the emptying of the draining cavity 41. This allows the draining cavity 41 to accommodate more impurities for draining, reducing the cleaning cycle of the impurity removal well 3 and making it highly practical.

[0049] Reference Figure 2 The side wall of the impurity removal well 3 is connected to a return pipe 6, which is used to recirculate the accumulated water at the bottom of the impurity removal well back into the main well 1. In this embodiment, the connection between the return pipe 6 and the impurity removal well 3 is higher than the connection between the return pipe 6 and the main well 1, thereby effectively improving the problem of liquid in the main well 1 flowing into the impurity removal well 3 through the return pipe 6, so that the accumulated water can flow in one direction.

[0050] Reference Figure 2 and Figure 4A cleaning box 8 is welded to the side wall of the sewage pipe 43. A drive assembly 9 is installed inside the cleaning box 8. A cleaning roller 81 is installed on the drive assembly 9. The cleaning roller 81 is coaxially arranged with the return pipe 6. Several bristles 811 are provided on the periphery of the cleaning roller 81. The drive assembly 9 drives the cleaning roller 81 to move towards the return pipe 6. During the movement, the cleaning roller 81 is driven to rotate, thereby cleaning the sludge and other deposits attached to the inner wall of the return pipe 6 and reducing the probability of blockage of the return pipe 6.

[0051] Reference Figure 2 and Figure 4 The drive assembly 9 includes a drive motor 91, a drive sleeve 92, a drive screw 93, a spline shaft 94, and a spline tube 95. The drive sleeve 92 passes through the inner wall of the cleaning box 8 and is coaxially arranged with the return pipe 6. The drive screw 93 is threaded to the inner wall of the drive sleeve 92. The cleaning roller 81 is sleeved on the peripheral wall of the drive screw 93 extending out of the cleaning box 8. When the drive screw 93 and the drive sleeve 92 are threaded together, the cleaning roller 81 can be driven to rotate and move towards the return pipe 6, thereby cleaning the inner wall of the return pipe 6.

[0052] Reference Figure 2 and Figure 4 The stator of the drive motor 91 is bolted to the inner wall of the cleaning box 8. The output shaft of the drive motor 91 is coaxially arranged with the drive sleeve 92. The spline shaft 94 is welded to the end wall of the output shaft of the drive motor 91. The spline tube 95 is welded to the end wall of the drive screw 93 inserted into the cleaning box 8. The end of the spline shaft 94 facing away from the drive motor 91 is inserted into the inner wall of the spline tube 95.

[0053] Reference Figure 4 and Figure 5 The spline tube 95 has several oil passage holes 951 on its end wall, which are filled with lubricating oil and are connected to the inner cavity of the spline tube 95. This lubricates the spline shaft 94 and the spline tube 95, reducing the friction between them. Through the snap-fit ​​engagement between the spline shaft 94 and the inner cavity of the spline tube 95, the drive screw 93 is driven to rotate under the drive of the drive motor 91. At the same time, the spline shaft 94 will gradually extend out of the spline tube 95. However, due to the snap-fit ​​relationship between the two, the transmission function can continue, so that the cleaning tube rotates and moves towards the return tube 6 to clean the inner wall of the return tube 6.

[0054] Reference Figure 2 and Figure 6A baffle 7 is provided on the bottom wall of the cleaning well 3. A rotating shaft 71 is provided through the baffle 7 along its thickness direction. The rotating shaft 71 is rotatably connected to the baffle 7 through a bearing. Several scrapers 72 are welded to the peripheral wall of the end of the rotating shaft 71 that extends out of the baffle 7. The scrapers 72 abut against the surface of the baffle 7. A rotating component 73 is provided at the bottom of the baffle 7. In this embodiment, the rotating component 73 is a motor. The output shaft of the rotating component 73 is connected to the rotating shaft 71 by a key connection, so as to drive the rotating shaft 71 and the scrapers 72 to rotate, thereby scraping the sediment carried by the water on the surface of the baffle 7 to prevent solidification.

[0055] Reference Figure 2 and Figure 6 The rotating shaft 71 is hollow inside, and a venting chamber 721 is provided inside the scraper 72. The venting chamber 721 is connected to the hollow part inside the rotating shaft 71. Several air outlets 722 are provided on the side wall of the scraper 72, and all air outlets 722 are connected to the venting chamber 721. Each air outlet 722 is equipped with a one-way valve 723 on its inner wall, allowing gas to enter the impurity removal well channel 3, while preventing water in the impurity removal well channel 3 from entering the venting chamber 721. A venting disc 74 is fitted on the peripheral wall of the rotating shaft 71 below the partition 7. The venting disc 74 is connected to the partition 721. The bottom wall of plate 7 is connected to the air vent 74, which is hollow inside. Several air pumps 75 are connected to the air vent 74. An air inlet 711 is opened on the peripheral wall where the rotating shaft 71 abuts against the air vent 74. The air in the air vent 74 will enter the air vent 721 through the air inlet 711. While the scraper 72 is rotating, the gas is discharged from the air outlet 722, forming bubbles. The silt and other impurities scraped by the scraper 72 are wrapped and formed into foam, which is carried to the surface of the water and discharged through the return pipe 6 to prevent silt blockage inside the impurity removal well channel 3.

[0056] The implementation principle of the smart city rainwater and sewage pipeline diversion system in Embodiment 2 of this application is as follows: After rainwater or sewage enters the main shaft 1, it is filtered through the primary filter 11 and the secondary filter 12 and discharged smoothly. Meanwhile, the impurities on the surface of the primary filter 11 and the secondary filter 12 enter the impurity removal shaft 3 and fall into the drainage chamber 41 for drainage. After the drainage is completed, the impurity removal component 5 will discharge the impurities into the impurity removal box 44 through the cleaning port 42 for unified cleaning. This allows the impurity removal shaft 3 to carry more impurities for drainage treatment, reducing the cleaning frequency of the impurity removal shaft 3 and reducing labor intensity.

[0057] When the water level in the cleaning well 3 becomes too high, it can enter the main well 1 through the return pipe 6 to drain the water. During this process, the drive assembly 9 will drive the cleaning roller 81 to clean the inner wall of the return pipe 6 to prevent blockage. At the same time, the scraper 72 will rotate and generate air bubbles to prevent dust and dirt in the water from settling, thereby effectively protecting the cleanliness of the inside of the cleaning well 3 and reducing the frequency of cleaning the cleaning well 3. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
