DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0020] Please refer to Figures 1-10 The present application provides a technical solution: a self-cleaning environment-friendly drainage pipeline, comprising a filter screen 3 arranged inside a water pipe 1 for filtering impurities in water, further comprising: a first cleaning unit 4 arranged inside the water pipe 1 and connected with a power unit 2 arranged on the water pipe 1, for cleaning the inner wall of the water pipe 1; and a second cleaning unit 5 arranged inside the water pipe 1 and connected with the power unit 2, for cleaning the filter screen 3.

[0021] It should be noted that in operation, the first cleaning unit 4 and the second cleaning unit 5 are installed inside the water pipe 1 and connected with the power unit 2 inside the water pipe 1, sewage flows in from the water inlet end 11 and then flows out from the water outlet end 12, and then passes through the filter screen 3 inside the water pipe 1 to clean the impurities in the sewage. When it is necessary to clean the water pipe 1 and the filter screen 3 inside it, the power unit 2 is turned on to drive the second cleaning unit 5 to rotate, thereby cleaning the impurities on the filter screen 3, and the power unit 2 drives the first cleaning unit 4 to rotate, thereby cleaning the impurities on the inner wall of the water pipe 1. The first cleaning unit 4 and the second cleaning unit 5 are driven by the same power source, realizing synchronous cleaning of the inner wall of the water pipe 1 and the filter screen 3, effectively removing the dirt attached to the inner wall of the water pipe 1 and the impurities remaining in the filter screen 3 to prevent the mesh from being blocked, and the double-unit cooperative work ensures the cleaning of the entire pipeline, significantly reducing the problem of reduced drainage efficiency caused by impurity deposition or filter screen blockage.

[0022] In an embodiment, the power unit 2 comprises: a motor 21 arranged on the water pipe 1; a rotating shaft 22 arranged at the power output end of the motor 21 and penetrating through the water pipe 1, that is, the rotating shaft 22 penetrates through the pipe wall of the water pipe 1 and forms a dynamic seal with the pipe wall; a transmission member 23 arranged on the filter screen 3 away from the water inlet end 11 of the water pipe 1 and connected with the rotating shaft 22; and a transmission shaft 24 penetrating through the filter screen 3 and connected with the transmission member 23.

[0023] In this way, referring to Figures 1-9 , a single motor 21 is used as a power source, and the first cleaning unit 4 and the second cleaning unit 5 are synchronously driven through the linkage of the rotating shaft 22 and the transmission member 23. Compared with the traditional multiple motor 21 distributed driving scheme, the number of power equipment is reduced, the installation space is saved, the narrow environment inside the water pipe 1 is adapted, the transmission member 23 is arranged on the side of the filter screen 3 away from the water inlet end 11 and directly connected with the rotating shaft 22, and the power is transmitted to the first cleaning unit 4 and the second cleaning unit 5 through the transmission shaft 24. This layout shortens the power transmission path and reduces energy loss. The transmission member 23 transmits the kinetic energy of the rotating shaft 22 to the transmission shaft 24, and then drives the first cleaning unit 4 and the second cleaning unit 5 inside the water pipe 1 to clean the inner wall of the water pipe 1 and the filter screen 3.

[0024] In an embodiment, the transmission member 23 comprises: a protective box 231 fixed on the filter screen 3; a first gear 232 fixed on the side of the rotating shaft 22 away from the motor 21 and located inside the protective box 231; and a second gear 233 fixed on the transmission shaft 24 and located on the side of the protective box 231 and meshed and connected with the first gear 232.

[0025] In this way, referring to Figure 9 , the meshing connection of the first gear 232 and the second gear 233 realizes precise power transmission between the rotating shaft 22 and the transmission shaft 24, ensures stable power output to the first cleaning unit 4 and the second cleaning unit 5, and seals the gear set inside the protective box 231 to protect the gear set.

[0026] In an embodiment, the first cleaning unit 4 comprises: a mounting disc 41 arranged on the side of the transmission shaft 24 close to the water inlet end 11; a support assembly 42 arranged on the mounting ring 411 of the outer circular end face of the mounting disc 41 at an equal angle; and a cleaning plate 43 arranged on the side of the support assembly 42 away from the mounting disc 41 and abutting against the inner wall of the water pipe 1, used for cleaning impurities on the inner wall of the water pipe 1.

[0027] In this way, referring to Figures 1-8The support assembly 42 is equiangularly arranged on the mounting ring 411 of the mounting disc 41, which ensures that the cleaning plates 43 are uniformly distributed around the inner wall of the water pipe 1, so that the cleaning plates 43 can effectively clean the impurities on the surface of the water pipe 1. The adjustable feature of the support assembly 42 enables the cleaning plates 43 to adapt to water pipes 1 of different diameters. When the inner wall of the water pipe 1 is uneven or the thickness of the dirt changes, the support assembly 42 can automatically adjust the radial displacement of the cleaning plates 43 to maintain close contact with the water pipe 1, thereby avoiding damage to the water pipe 1 caused by hard scraping.

[0028] In an embodiment, the support assembly 42 comprises a moving rod 421 arranged in the mounting ring 411, a connecting plate 422 arranged on the side of the moving rod 421 away from the mounting disc 41 and fixedly connected with the cleaning plate 43, and an elastic member 425 arranged inside the mounting ring 411 between the mounting disc 41 and the moving rod 421. The elastic member 425 is made of a spring with damping or an elastic pad.

[0029] In this way, referring to Figures 4-8 , the moving rod 421 is arranged in the mounting ring 411 and can slide freely in the radial direction, so that the cleaning plates 43 can automatically adjust their positions according to the actual state of the inner wall of the water pipe 1 (such as changes in the pipe diameter and the thickness of the dirt). The elastic member 425 is arranged inside the mounting ring 411. When the cleaning plates 43 are installed inside the water pipe 1, the cleaning plates 43 are pressed towards the inside of the mounting ring 411. At this time, the moving rod 421 presses the elastic member 425 inside the mounting ring 411. Then, when the cleaning plates 43 are released after being installed inside the water pipe 1, the cleaning plates 43 can abut against the inner wall of the water pipe 1 under the action of the elastic member 425. When the motor 21 rotates, the rotational shaft 22 transmits kinetic energy to the transmission shaft 24, and then the rotational shaft 22 drives the cleaning plates 43 to rotate inside the water pipe 1, thereby cleaning the impurities attached to the inner wall of the water pipe 1. When the inner wall of the water pipe 1 is uneven or dirt accumulates, the elastic member 425 absorbs the displacement change by compression or stretching, thereby ensuring that the cleaning plates 43 always closely adhere to the pipe wall and avoiding cleaning dead angles.

[0030] In an embodiment, the mounting disc 41 is provided with a mounting groove 4101 for placing the elastic member 425.

[0031] In this way, referring to Figure 8 , the mounting groove 4101 provides a specific mounting position for the elastic member 425. Through the axial constraint of the groove wall, the elastic member 425 is prevented from deviating or falling off during compression or stretching, thereby ensuring that it always exerts force in the radial direction stably.

[0032] In one embodiment, the support assembly 42 further includes: a fixing frame 412 disposed on the side of the mounting ring 411 away from the mounting plate 41; a guide rod 423 disposed on the side of the connecting plate 422 near the fixing frame 412 and passing through the fixing frame 412; and a limiting block 424 disposed on the side of the guide rod 423 away from the connecting plate 422.

[0033] This design is for reference. Figure 7 ,as well as Figure 8 The guide rod 423 passes through the guide hole of the fixed frame 412 and has a certain guiding function, forming a linear motion pair. The cleaning plate 43 is forced to move only radially, avoiding tilting, swaying or jamming caused by uneven force applied by the elastic element 425 or water flow impact in the pipe. This allows the cleaning plate 43 to move in the specified direction, improving the cleaning efficiency of the cleaning plate 43.

[0034] In one embodiment, the second cleaning unit 5 includes: a mounting bracket 51 disposed on the drive shaft 24; and a cleaning assembly 52 disposed on the mounting bracket 51 for cleaning impurities on the filter screen 3.

[0035] This design is for reference. Figures 4-8 The mounting bracket 51 is directly fixed to the drive shaft 24 and rotates synchronously with the drive shaft 24. Its rotation trajectory is completely in contact with the surface of the filter screen 3, ensuring that the cleaning component 52 can cover the entire effective filtration area of ​​the filter screen 3. The cleaning component 52 can be close to the surface of the filter screen 3 or embedded in the gap of the filter screen, improving the cleaning efficiency of the filter screen 3.

[0036] In one embodiment, the cleaning component 52 includes: a cleaning shaft 521 disposed on the mounting bracket 51; and cleaning brushes 522 disposed at intervals on the cleaning shaft 521 for brushing impurities in the filter screen 3.

[0037] This design is for reference. Figure 7 ,as well as Figure 8 When the cleaning shaft 521 rotates under the drive of the mounting bracket 51, it can drive the cleaning brush 522 to rotate on the surface of the filter screen 3, so that the cleaning brush 522 can brush the surface of the filter screen 3. The cleaning brush 522 contacts the surface of the filter screen 3, effectively removing tiny particles and adhesive dirt from the pores of the filter screen 3. The cleaning brush 522 rotates at high speed with the cleaning shaft 521, and through the high-frequency friction and beating action of the bristles, it accelerates the removal of impurities, which is especially suitable for removing entangled fibrous dirt.

[0038] In one embodiment, the second cleaning unit 5 further includes a transmission assembly 53 disposed between the cleaning shaft 521 and the water pipe 1, for driving the cleaning shaft 521 to rotate; the transmission assembly 53 includes a main gear 531 fixed on the side of the cleaning shaft 521 away from the transmission shaft 24 and a driven gear 532 disposed on the inner wall of the water pipe 1 and meshing with the main gear 531.

[0039] Thus designed, referring to Figure 10 , the main gear 531 on the cleaning shaft 521 engages with the fixed gear 532 on the inner wall of the water pipe 1 during rotation, so that the cleaning shaft 521 rotates on the mounting frame 51, and the cleaning brush 522 can make the bristles have a downward insertion action during rotation, thereby pushing out the impurities attached in the mesh of the filter screen 3, and improving the cleaning efficiency of the filter screen 3.

[0040] In addition, if the description of "first", "second" and the like is involved in the embodiments, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features with "first", "second" can explicitly or implicitly include at least one of the features.
