DETAILED DESCRIPTION

[0027] The application will be further described in detail below with reference to the drawings.

[0028] The embodiment of the application discloses a city drainage pipe which is convenient to dredge and prevent blockage, referring to Figure 1 , comprising a pipe body 1, and the pipe body 1 is internally provided with an anti-blocking structure 2; the pipe body 1 comprises a vertical water inlet pipe 11 and a horizontally extended water outlet pipe 12, and the anti-blocking structure 2 is arranged to reduce the blockage of the water outlet pipe 12.

[0029] Referring to Figure 1The anti-clogging structure 2 includes a water storage pipe 21 disposed on the side wall of the water inlet pipe 11; the water storage pipe 21 extends upward to the inlet of the water inlet pipe 11, and a number of drainage holes 211 are provided on the upper side wall of the water storage pipe 21; the water storage pipe 21 extending upward to the inlet of the water inlet pipe 11 is easier to store water; the drainage holes 211 provided on the upper side wall of the water storage pipe 21 prevent excessive water accumulation in the water storage pipe 21, and only maintain a certain amount of water storage at the bottom of the water storage pipe 21.

[0030] Reference Figure 1 , 2 The anti-blocking structure 2 also includes an anti-blocking plate 22, which consists of an annular ring 221 that fits the shape of the inner wall of the water outlet pipe 12 and a number of connecting rods 222 that radiate circumferentially from the center of the annular ring 221 to the inner side wall of the annular ring 221. Drainage holes 211 are formed between the spaced connecting rods 222. The annular ring 221 fits better against the inner wall of the water outlet pipe 12 to achieve a sludge removal effect, and the connecting rods 222 improve the structural strength and can intercept debris such as tree branches.

[0031] Reference Figure 1 , 2 The anti-blocking structure 2 also includes a movable block 23 fixed on the anti-blocking plate 22. A movable groove 121 is provided in the water outlet pipe 12, and the movable groove 121 is connected to the water storage pipe 21. The movable block 23 is slidably connected to the movable groove 121.

[0032] Reference Figure 1 , 2 The anti-blocking structure 2 also includes a float 24 connected to the moving block 23. A downwardly recessed positioning groove 3 is provided at the connection between the moving groove 121 and the water storage pipe 21, and the float 24 is positioned in the positioning groove 3. An extension rod 231 is fixedly extended from the side wall of the moving block 23. A connecting rope 232 is fixed to the end of the extension rod 231, and the other end of the connecting rope 232 is fixed to the float 24. The rigid extension rod 231 improves the stability of the float 24 during movement.

[0033] Reference Figure 1 A reset rope 241 is connected to the side of the float 24 away from the extension rod 231. The other end of the reset rope 241 is wrapped around and connected to the port of the water inlet pipe 11 for resetting the float 24 and the anti-blocking plate 22 after they have moved. It should also be noted that there is a sliding groove between the moving groove 121 and the positioning groove 3 for the float 24 to slide. The float 24 will not fall into the moving groove 121, which makes it easy to pull the reset rope 241 to achieve convenient resetting of the float 24.

[0034] Reference Figure 1 , 2A sealing sleeve is fixed on the side wall of the movable block 23, so that the movable block 23 is sealed when it is placed in the movable groove 121, which can cut off the water flow and make the water overflow the positioning groove 3, causing the float 24 to float. It should be noted that the height of the movable groove 121 is the same as the height of the float 24, which facilitates the movement of the float 24 in the movable groove 121 and realizes the operation of resetting the float 24 to be placed in the positioning groove 3.

[0035] Reference Figure 1 , 2 The movement of the movable block 23 within the movable groove 121 is driven by the drive structure 4. The drive structure 4 includes a drive rod 41 and a drive spring 42. The drive rod 41 is fixed to the opposite side of the movable block 23 and the float 24 and passes through the side wall of the water outlet pipe 12. The drive spring 42 is fixed between the drive rod 41 and the side wall of the water outlet pipe 12. A sealing sleeve is also fixed on the drive rod 41 to prevent water flow from eroding the drive spring 42. The elastic force of the drive spring 42 causes the movable block 23 and the anti-blocking plate 22 to have a force to move in the direction of water outlet of the water outlet pipe 12. When the float 24 is dislodged from the positioning groove 3, the annular ring 221 and the connecting rod 222 move, which facilitates the cleaning of branches, debris and silt.

[0036] 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 in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
