DETAILED DESCRIPTION

[0019] Embodiment 1, as Figures 1 to 6As shown, a municipal road traffic drainage system disclosed in the present invention includes a main drainage pipe 1 and a branch drainage pipe 2 vertically arranged on the upper side of the main drainage pipe 1. The cross-sections of the main drainage pipe 1 and the branch drainage pipe 2 are both circular. The main drainage pipe 1 extends in a horizontal direction. One main drainage pipe 1 may correspond to multiple branch drainage pipes 2. The main drainage pipe 1 is used to collect sewage discharged from the branch drainage pipe 2 and then discharge it.

[0020] Among them, in the present invention, a protective tube 3 is coaxially installed on the inner wall of the main drainage pipe 1, and a rounded corner can be set at the front end of the protective tube 3 to avoid the accumulation of foreign matter. A through hole 4 connected to the branch drainage pipe 2 is opened on the pipe wall of the protective tube 3. By setting the protective tube 3, sewage enters the protective tube 3 through the through hole 4. The inner surface of the protective tube 3 is smooth, and it is used to replace the main drainage pipe 1 to receive the sewage above, avoiding the damage caused by the long-term erosion of sewage to the inner surface of the main drainage pipe 1, thereby reducing the problem of pipe blockage caused by dirt staying and accumulating at the damaged place.

[0021] Furthermore, a scraper assembly 5 is slidably installed on the inner side of the protection pipe 3. The scraper assembly 5 is in the shape of a circular ring as a whole. The scraper assembly 5 is connected to an impeller assembly 7 through a transmission system 6. The impeller assembly 7 is installed on the inner side of the branch drainage pipe 2. The scraper assembly 5 includes a bottom ring 8 and a digging ring 9 coaxially connected to the bottom ring 8. The water flows from the front end to the rear end of the main drainage pipe 1. The bottom ring 8 is located at the front end, and the digging ring 9 is located at the rear end. The scraper assembly 5 is connected to the transmission system 6 through the bottom ring 8. After the sewage enters the branch drainage pipe 2, the gravity of the sewage can act on the impeller assembly 7. The gravity of the sewage drives the impeller assembly 7 to rotate. The impeller assembly 7 can act on the scraper assembly 5 through the transmission system 6. The digging ring 9 at the rear end of the scraper assembly 5 contacts the dirt. The transmission system 6 can drive the scraper assembly 5 to move axially to scrape the dirt on the inner wall of the protection pipe 3.

[0022] In the embodiment of the present invention, the outer diameters of the bottom ring 8 and the excavation ring 9 correspond to the inner diameter of the protective tube 3, thereby cleaning the protective tube 3. The movement of the scraper ring assembly 5 is powered by the impeller assembly 7, thereby reducing energy waste. In addition, the mechanical structure is adopted to ensure more stable operation.

[0023] In this embodiment, a threaded ring 10 is coaxially fixed to one end of the tunneling ring 9, and correspondingly, an internal thread is provided on the inner side of the bottom ring 8, and an annular groove 11 is provided on the other end of the tunneling ring 9. The threaded ring 10 cooperates with the inner thread of the bottom ring 8, and a first support spring 12 is fixed to the end face of the bottom ring 8. The first support spring 12 is also fixed with an annular guide rail 13, and the annular guide rail 13 is rotatably engaged in the annular groove 11. When the bottom ring 8 starts to move from front to back along the axial direction, it can drive the tunneling ring 9 to move together. When the tunneling ring 9 encounters accumulated dirt, the dirt can react on the tunneling ring 9 and compress the first support spring 12, and the tunneling ring 9 and the bottom ring 8 are relatively displaced. At this time, the tunneling ring 9 can rotate around the axis under the cooperation of the thread. The combination of rotation + displacement is more conducive to the removal of dirt.

[0024] In this embodiment, the transmission system 6 includes a bracket 15, a rack 16, a first spur gear 17, a first transmission shaft 18, a first support 19, a first bevel gear 20, a second bevel gear 21, a second transmission shaft 22, a second support 23, a second spur gear 24 and a ring gear 25. One end of the bracket 15 is connected to the scraper ring assembly 5, and the other end of the bracket 15 is connected to the rack 16. The rack 16 is slidably matched with the main drainage pipe 1, and the rack 16 is also arranged in the horizontal direction. One end of the rack 16 extends into the branch drainage pipe 2 and is connected to the bracket 15, and the other end of the rack 16 extends out of the branch drainage pipe 2 and meshes with the first spur gear 17.

[0025] Among them, the first spur gear 17 is coaxially connected to the first bevel gear 20 through the first transmission shaft 18, the first transmission shaft 18 is supported by the first support 19 installed on the outer wall of the main drainage pipe 1, the first bevel gear 20 is meshed with the second bevel gear 21, the second bevel gear 21 is transmission-connected to the second spur gear 24 through the second transmission shaft 22, the first transmission shaft 18 is perpendicular to the second transmission shaft 22, the second spur gear 24 is meshed with the ring gear 25, the ring gear 25 is installed on the outside of the impeller assembly 7, the first transmission shaft 18 is rotatably installed on the main drainage pipe 1 through the first support 19, the second transmission shaft 22 is rotatably installed on the branch drainage pipe 2 through the second support 23, and the transmission system 6 also includes an elastic reset component 26 for restoring the position of the rack 16 to its original position.

[0026] In specific operation, when the impeller assembly 7 rotates under the action of water flow, the ring gear 25 on the outside of the impeller assembly 7 can drive the second spur gear 24 to rotate, the second spur gear 24 drives the second bevel gear 21 to rotate through the second transmission shaft 22, the second bevel gear 21 drives the first bevel gear 20 meshing therewith to rotate, the first bevel gear 20 drives the first spur gear 17 to rotate through the first transmission shaft 18, the first spur gear 17 drives the rack 16 meshing therewith to move, the rack 16 can drive the bottom ring 8 to move together through the bracket 15, thereby realizing the scraping of dirt.

[0027] Of course, in order to facilitate the normal transmission of the transmission system 6, a channel can be set on the outside of the transmission system 6, which is beneficial to the normal transmission of the transmission system 6 and avoids interference problems caused by contact with the formation.

[0028] In this embodiment, the elastic reset assembly 26 includes a reset torsion spring, and a reset torsion spring is installed between the first transmission shaft 18 and the first support 19. After the water flow stops impacting, the rack 16 can be restored to its original position under the action of the reset torsion spring, facilitating the smooth progress of the next cleaning cycle.

[0029] In this embodiment, a filter screen 27 is installed above the impeller assembly 7. The filter screen 27 is arranged in the branch drainage pipe 2, and can filter the sewage entering the impeller assembly 7 to reduce the accumulation of foreign matter. Later, the debris on the filter screen 27 can be cleaned in time to prevent the pipe from being blocked. The impeller assembly 7 includes a rotating ring 28 and a plurality of blades 29 evenly spaced inside the rotating ring 28. The rotating ring 28 is in rotational sealing cooperation with the middle part of the main drainage pipe 1, and the outer circle of the rotating ring 28 is in cooperation with the transmission system 6. After the water flow acts on the blades 29, the blades 29 can be driven to drive the rotating ring 28 to rotate. Ball bearings are arranged between the rotating ring 28 and the branch drainage pipe 2 to reduce the resistance during rotation.

[0030] In this embodiment, the protective tube 3 includes an upper semicircular tube 30 and a lower semicircular tube. The lower semicircular tube is formed by a plurality of fixed arc plates 31 and movable arc plates 32 staggered in the circumferential direction. The fixed arc plates 31 are fixed on the inner side of the main drainage pipe 1, and the movable arc plates 32 are connected to the bottom ring 8 through an elastic support assembly. If there is dirt accumulation, the dirt will cross multiple fixed arc plates 31 and movable arc plates 32 along the circumferential direction. The present invention arranges multiple movable arc plates 32. When the bottom ring 8 moves along the axial direction, the bottom ring 8 can drive the movable arc plates 32 to move together. The movement of multiple movable arc plates 32 staggered with the fixed arc plates 31 can cause relative displacement between the movable arc plates 32 and the fixed arc plates 31, thereby loosening the bottom of the dirt and preventing the dirt from solidifying on the inner wall of the lower semicircular tube, which is more conducive to the removal of foreign matter.

[0031] In this embodiment, a slide groove 33 is provided on the inner side of the movable arc plate 32, and a pin shaft 34 is fixed on the outer side of the bottom ring 8. The pin shaft 34 is slidably arranged in the slide groove 33, and the slide shaft is connected to the inner wall of the slide groove 33 through a second support spring 35. The second support spring 35 is used to elastically support the movable arc plate 32, so that the staggered distances between the multiple movable arc plates 32 and the fixed arc plate 31 can be kept irregular, which is more conducive to the removal of foreign matter.

[0032] Embodiment 2, as Figure 7As shown, the difference between this embodiment and embodiment 1 is that in this embodiment, a digging tooth 14 is provided on the end face of the digging ring 9 on the side away from the bottom ring 8. The digging teeth 14 are evenly spaced along the circumferential direction on the end face of one end of the digging ring 9. The digging teeth 14 are wedge-shaped and extend along the circumferential direction. In some other embodiments, the shape of the digging teeth 14 can be changed as needed. The main purpose is to crush the dirt through the digging teeth 14 before the digging ring 9 scrapes the inner wall of the protective pipe 3, so that the dirt can be removed more conveniently.

[0033] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
