The side of the drain pipe 10 is uniformly provided with the blockage removing groove 11, and the edge position of the blockage removing groove 11 is provided with the sawtooth-shaped sawtooth blade 20, so that when the blade body 18 moves in the blockage removing groove 11, the blade body 18 and the sawtooth blade 20 simultaneously generate a crushing effect on sundries, so that the sundries can be better crushed and further can be better discharged. The drain pipe 10 overcoat is equipped with clear stifled sleeve pipe 12, is provided with the installation pipe 13 of sliding with clear stifled sleeve pipe 12 on the well lid body 2, and the inboard of clear stifled sleeve pipe 12 is provided with clear stifled sword 14, and clear stifled sword 14 is gone deep into the drain pipe 10 through clear stifled groove 11 and is removed. A fixed connecting rod 2715 is arranged between the blockage removing sleeve 12 and the driving column 5, and a hidden groove 16 for installing the fixed connecting rod 15 is arranged on the well lid body 2.

The fixed connecting rod 15 is hidden in the hidden groove 16, and can ensure that the driving column 5 and the blockage removing sleeve 12 synchronously move up and down.

Because the blockage removing sleeve 12 is arranged in the mounting pipe 13 for sliding movement and the fixed connecting rod 15 is fixedly arranged between the blockage removing sleeve 12 and the driving column 5, when the driving column 5 moves up and down, the blockage removing sleeve 12 can also move up and down at the same time. The inner side of the blockage removing sleeve 12 is provided with the blockage removing knife 14, and the side surface of the drain pipe 10 is provided with the blockage removing groove 11, so that the blockage removing knife 14 can extend into the knife drain pipe 10 to crush sundries in the drain pipe 10, and the sundries in the drain pipe 10 are cleaned.

The lower extreme of drain pipe 10 still is provided with the mechanism of rocking that promotes drain pipe 10 and rock, rock the mechanism and include ejector pin 26, be connected with connecting rod 27 between ejector pin 26 and drain pipe 10, the both ends of connecting rod 27 rotate with ejector pin 26 and drain pipe 10 respectively and be connected, be provided with the slide opening 28 that slides with ejector pin 26 and be connected on the well lid body 2, slide opening 28 is in the diameter direction of well lid body 2, ejector pin 26 is provided with the oblique slider 29 that the inclined plane is downward for the other end that is connected with connecting rod 27, the drive post 5 lower extreme sets up the actuating lever 30 with oblique slider 29 contact, displacement about actuating lever 30 upper and lower displacement drive oblique slider 29, still be provided with between slide opening 28 and ejector pin 26 and make ejector pin 26 resume initial position third spring 31, when ejector pin 26 is located initial position, actuating lever 30 is located the position on the top of oblique slider 29.

Through setting up the rocking mechanism, and the articulated effect of articulated seat and articulated portion, reciprocate when drive post 5, actuating lever 30 reciprocates simultaneously, then actuating lever 30 drive ejector pin 26 horizontal migration, under the effect of third spring 31, actuating lever 30 makes drain pipe 10 swing on the horizontal direction through connecting rod 27, owing to the swing can make debris in the drain pipe 10 and clear stifled sword 14 produce relative displacement, consequently can be better smash debris, and the wobbling drain pipe 10 can be better discharge the debris after smashing, thereby reach the purpose of preventing blocking up.

The blockage clearing knife 14 comprises a knife body mounting seat 17 arranged on the inner wall of the blockage clearing sleeve 12, a knife blade body 18 which is arranged obliquely downwards is rotatably connected to the knife body mounting seat 17, and a second compression spring 19 is arranged on the knife blade body 18 and the inner wall of the blockage clearing sleeve 12. The blade body 18 comprises an upper blade 21 positioned above and a lower blade 22 positioned below, and the arrangement of the upper blade 21 and the lower blade 22 can enable the blockage removing sleeve 12 to generate a crushing effect on sundries in the processes of upward movement and downward movement, so that the blockage removing effect is better.

The blockage removing knife 14 is arranged in the structure, so when the sleeve moves downwards, the second compression spring 19 is in a stretching state, the knife edge body 18 is opened to better clean sundries, the sundries can be pulled by the pulling force of the second compression spring 19 to be discharged from the blockage removing groove 11 or the lower part of the drainage pipe 10, when the sleeve moves upwards, the sundries pile up the knife edge body 18 to generate pressure, the second compression spring 19 is in a compression state, the knife edge body 18 is in a contraction state, and the knife edge body 18 is easier to rise due to smaller resistance. The tip of the blade body 18 is provided with a sharpening mechanism which is a sharp body 23 having a gradually decreasing cross-sectional area from bottom to top when the second compression spring 19 is in a compressed state. Since the blade body 18 is made to rely on the elastic force of the spring when moving upward, the sharp body 23, which is provided such that the sectional area is gradually reduced from bottom to top, can reduce the resistance when moving upward, and at the same time, can generate enough pressure to the sundries when moving downward so that the sundries can be discharged out of the drain pipe 10 from below. The sharp body 23 in this embodiment is a cone or a regular tetrahedron.

When the drain hole 3 is filled with impurities, when a vehicle passes through the drainage well cover, the working state is as follows, firstly, the impurities are filled in the drain hole 3, meanwhile, the blade body 18 moves downwards, and due to the resistance of the second compression spring 19 and the impurities, the second compression spring 19 is in a stretching state, so that the blade body 18 is in an opening state, at the moment, the lower blade 22 generates a crushing effect, and simultaneously, the impurities are easier to be discharged due to the pressure generated by the lower surface of the sharp body 23 on the impurities; when the knife edge body 18 moves upwards, the second compression spring 19 is in a compressed state due to the resistance of the sundries, the knife edge body 18 is in a closed state, the shape design of the sharp body 23 enables the resistance of the upward movement to be small, and the upper knife edge 21 can also generate a smashing effect on the sundries. In addition, as the driving column 5 moves downwards, the top rod 26 is driven by the driving rod 30 to enable the clean water pipe to swing in the horizontal direction, the swinging can enable sundries in the drain pipe 10 and the blockage removing knife 14 to generate relative displacement, the sundries can be better crushed, and the crushed sundries can be better discharged by the swinging drain pipe 10.

In summary, the invention utilizes the pressure of the vehicle to make the blockage removing sleeve 12 move up and down, the blockage removing knife 14 arranged at the inner side of the blockage removing sleeve 12 generates blockage removing effect on sundries in the drain pipe 10, the existence of the shaking mechanism can further improve the crushing effect and is beneficial to discharging the crushed sundries, and meanwhile, the blockage removing knife 14 in the invention can be used for corresponding crushing during the upward and downward movement, thereby having good blockage removing effect.
