The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering. In order to prevent road surface water accumulation, drainage pipes are often arranged underground for drainage;

[0003] After retrieval, a Chinese patent with the publication number of CN220847926U discloses a drainage device for municipal drainage. It is recorded in this patent that air quickly enters the next section of the drainage pipe and impacts the inner wall of the drainage pipe, which can effectively disperse the garbage inside the drainage pipe. And a filter screen is arranged in the air inlet groove to prevent impurities from entering the inside of the air guide pipe. By arranging an air guide pipe above the drainage pipe and using the water flow to drive the air to flow quickly when it enters the inside of the drainage pipe, the garbage in the next section inside the drainage pipe can be dispersed and cleaned, effectively playing a role in preventing blockage.

[0004] In this scheme, the cleaning effect of the air impact force is affected by various factors, such as air flow rate, pressure, impact angle, etc. These factors lead to inconsistent cleaning effects and cannot completely solve the garbage problem. And under the long-term action of the air impact force, the filter screen will be damaged or worn, thus reducing its service life and increasing the maintenance cost. To solve this technical problem, the utility model proposes a drainage device for municipal use. Summary of the Invention

SPECIFIC EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] Embodiment 1: A drainage device for municipal use includes a drainage elbow 1. The drainage elbow 1 consists of a vertical end and a horizontal section. A motor 6 is fixedly connected to the outer wall of the vertical section of the drainage elbow 1. The output end of the motor 6 is fixedly connected to a rotating rod 8. A support block 7 is fixedly connected to the outer wall of the vertical section of the drainage elbow 1, and the rotating rod 8 is rotatably connected within the support block 7. The other end of the rotating rod 8 is fixedly connected to a first bevel gear 9. A connecting rod 11 is rotatably connected inside the horizontal section of the drainage elbow 1. At the same time, a second bevel gear 10 is fixedly connected to the left end of the connecting rod 11, and the second bevel gear 10 meshes with the first bevel gear 9. A second filter screen 16 is fixedly connected inside the horizontal section of the drainage elbow 1. A positioning sleeve 15 is fixedly connected to the outer wall of the second filter screen 16. A connecting frame 13 is fixedly connected to the outer wall of the right end of the connecting rod 11. A plurality of scraping rods 14 are fixedly connected to the outer wall of the connecting frame 13, and the scraping rods 14 are slidably connected within the second filter screen 16. The connecting rod 11 passes through the drainage elbow 1 and extends to the outside of the drainage elbow 1, and the right end of the connecting rod 11 is rotatably connected within the positioning sleeve 15. The connecting rod 11 is connected to the drainage elbow 1 through a sealing ring 12.

[0026] After the wastewater is filtered through the second filter screen 16, it will become clogged over time. To solve this problem, by starting the motor 6 outside the drainage elbow 1, the rotating rod 8 is driven, and then the first bevel gear 9 is driven to rotate. The movement of the first bevel gear 9 causes the second bevel gear 10 to rotate, and then the connecting rod 11 and the connecting frame 13 are driven. The movement of the connecting frame 13 drives the plurality of scraping rods 14 on the outer wall to reciprocally rotate along the filter grooves within the second filter screen 16, and the impurities in the filter screen are removed by the scraping rods 14. At the same time, the connecting rod 11 is accurately positioned through the positioning sleeve 15. This process effectively improves the smoothness of wastewater discharge, reduces the complex operations that require manual cleaning, and thus significantly improves the work efficiency.

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that a manhole cover 2 is provided at the top of the drainage elbow 1. At the same time, a first filter plate 3 is fixedly connected inside the upper part of the vertical section of the drainage elbow 1, and the first filter plate 3 is inclined to the right. A first sewage discharge pipe 4 is provided on the right side of the output end of the drainage elbow 1. The other end of the first sewage discharge pipe 4 is provided with a cover 5, and the first sewage discharge pipe 4 corresponds to the inclined direction of the first filter plate 3. A second sewage discharge pipe 17 is vertical at the bottom of the vertical section of the drainage elbow 1, and the other end of the second sewage discharge pipe 17 is provided with a cover 18.

[0028] The first filter plate 3 is arranged obliquely to filter larger debris in the wastewater. These debris will be intercepted on the first filter plate 3 and enter the first sewage discharge pipe 4 along the inclined angle. When the debris accumulates to a certain extent, the cover 5 can be directly opened to take out the accumulated debris. In addition, the impurities accumulated at the bottom of the drainage elbow 1 can also be removed through the sewage discharge pipe 17 by opening the cover 18.

[0029] Working principle: When the municipal uses this device for drainage, first, the wastewater enters through the vertical section of the drainage elbow 1. After passing through the first filter plate 3 and being filtered, larger debris will be intercepted on the first filter plate 3. Since the first filter plate 3 is inclined, it will drain into the first sewage outlet pipe 4. When there is a large accumulation, the cover 5 can be directly opened and the debris can be taken out. The pumped wastewater continues to flow downward. At this time, the wastewater passes through the second filter net 16 to filter out smaller debris. After long-term filtration, it may become blocked. At this time, the motor 6 outside the drainage elbow 1 is started. Under the action of the motor 6, the rotating rod 8 is driven to rotate. When the rotating rod 8 rotates, it drives the first bevel gear 9 to rotate. When the first bevel gear 9 rotates, it drives the meshing-connected second bevel gear 10 to rotate. When the second bevel gear 10 rotates, it drives the connecting rod 11 and the connecting frame 13 to rotate. When the connecting frame 13 rotates, it drives the multiple scraping rods 14 on the outer wall to rotate. And the scraping rods 14 will rotate reciprocally along the filter grooves in the second filter net 16. At the same time, when the connecting rod 11 rotates, it is positioned through the positioning sleeve 15. Through the rotation of the scraping rods 14, the impurities in the second filter net 16 are cleaned up. At the same time, the cover 2 can also be opened, and the impurities accumulated at the bottom of the drainage elbow 1 can be cleaned through the sewage outlet pipe 17, so that the wastewater is discharged more smoothly, reducing the complex operation of manual cleaning and improving the work efficiency.
