[0030] Preferably, the crushing blade 10 and the movable rod 82 can be connected by bolts to facilitate replacement of the crushing blade 10 .
[0031] The cleaning component 9 includes a water pump 91, a connecting pipe 92 and a water outlet cover 93. The water pump 91 is fixed on the inner side of the protection box 5. The water inlet end of the water pump 91 is connected to the water inlet pipe. The water inlet pipe passes through the side wall of the protection box 5 and extends to the outside of the protection box 5. The end of the water inlet pipe extends into the water tank or the pool. The water outlet end of the water pump 91 is connected to the water outlet cover 93 through the connecting pipe 92. The water outlet cover 93 is movably mounted on the annular outer end of the movable rod 82. A hollow sleeve 84 is arranged at the lower end of the water outlet cover 93. The hollow sleeve 84 is mounted on the outer side of the movable rod 82 and the bottom end of the hollow sleeve 84 is fitted with the bottom end of the inner part of the protection box 5. The water is transported to the water outlet cover 93 by the water pump 91 and discharged through the water outlet cover 93, so as to flush out the crushed impurities inside the drain pipe and effectively alleviate the problem of water pipe blockage.
[0032] Two electric cylinders 7 are fixed on the upper end of the transverse support plate 4, and the shell of the electric cylinder 7 vertically penetrates the transverse support plate 4 and the top of the protection box 5. The lower end of the piston rod of the electric cylinder 7 is fixed to a connecting plate 85, and the connecting plate 85 is rotatably mounted on the annular outer end of the movable rod 82.

The buckle can be a flat-mouth buckle. The door panel 6 can be opened to facilitate the inspection and maintenance of the components inside the protection box 5.
[0035] Working process: When the municipal drainage needs to be dredged inside the drainage pipe after long-term use, move the support frame 1 to a suitable position, make the crushing knife 10 face the drainage pipe, press the switch of the electric cylinder 7, turn on the power of the electric cylinder 7, and the electric cylinder 7 drives the connecting plate 85 to move downward, thereby driving the movable rod 82 to move downward, and then drives the crushing knife 10 to move downward. When the crushing knife moves to a suitable position inside the drainage pipe, turn off the power of the electric cylinder 7, and then press the switch of the motor 3 to turn on the power of the motor 3. The motor 3 drives the hollow cylinder 81 and the movable rod 82 to rotate, thereby driving the crushing knife 10 to rotate, and the rotating crushing knife 1 0 crushes the impurities in the drainage pipe, and at the same time presses the power of the water delivery pump 91, uses the drain pump 91 to convey water to the water outlet cover 93, and discharges from the water outlet cover 93, and rushes into the drainage pipe along the hollow sleeve 84, and the crushed impurities are rushed into the lower pipe connected to the drainage pipe. The two-way action of the crushing knife 10 and the water flow punching can effectively remove the impurities in the drainage pipe and solve the blockage problem. Compared with the prior art, it saves the steps of pulling the dredging pipe outwards for many times during cleaning and removing the impurities on the surface of the dredging pipe, effectively improving the dredging efficiency, and water can be used as a lubricant to reduce the wear of the blade and increase the service life.
[0036] The electric cylinder 7 can adjust the position of the crushing knife 10 in the drainage pipe, so as to crush impurities at different positions in the drainage pipe. The electric cylinder 7 and the motor 3 can work simultaneously, so that the crushing knife 10 can rotate and move vertically at the same time to realize the impurity crushing work.
[0037] Embodiment 2:
[0038] See also Figure 3 and Figure 4 The water outlet cover 93 includes an annular hollow cylinder 931 connected to the connecting pipe 92, the outer end of the annular hollow cylinder 931 is fixedly connected to the inner wall of the protection box 5, a rotating annular plate 932 is arranged at the lower end of the annular hollow cylinder 931, and a rotating driving member is installed on the outer side of the rotating annular plate 932. A plurality of through holes 938 are provided at the lower end of the annular hollow cylinder 931, and a plurality of large water outlet holes 936 and small water outlet holes 937 that pass through the upper and lower parts are provided in the rotating annular plate 932. The rotating annular plate 932 is arranged at the upper end of the hollow sleeve 84, and the annular hollow cylinder 931 and the rotating annular plate 932 are both rotatably mounted on the annular outer end of the movable rod 82.
[0039] Working process: When water is flushed into the sewer pipe as described in the first embodiment, the through hole 938 at the lower end of the annular hollow cylinder 931 corresponds to the position of the large water outlet hole 936 on the rotating annular plate 932. At this time, it is only necessary to ensure the water flow rate without a large water pressure. After the impurities in the drainage pipe are initially removed, the electric cylinder 7 is used to remove the crushing knife 10 from the drainage pipe. At this time, some impurities will inevitably adhere to the crushing knife 10. The rotating driving member is used to drive the rotating annular plate 932 to rotate. The rotating drive member stops rotating until the through hole 938 at the lower end of the annular hollow cylinder 931 corresponds to the small water outlet hole 937 on the rotating annular plate 932. At this time, since the water outlet aperture becomes smaller and the water volume remains unchanged, the water discharged from the small water outlet hole 937 has a greater pressure than the water originally discharged from the large water outlet hole 936. The crushing knife 10 is driven to rotate by the motor 3, and the large water pressure is flushed on the rotating crushing knife, which makes it easy to remove impurities adhering to the crushing knife 10, thereby cleaning the crushing knife 10.
[0040] The diameter of the annular hole between the annular hollow cylinder 931 and the rotating annular plate 932 is slightly larger than the shaft diameter of the movable rod 82, so as to facilitate the rotation and up and down movement of the movable rod 82.
[0041] Embodiment three:
[0042] See also Figure 3 and Figure 4 The rotating driving member includes a ring gear 933 embedded in the outer end of the rotating ring plate 932 and a rack 934 meshed with the rear end of the ring gear 933. The right end of the rack 934 is connected to the electric telescopic rod 935, and the electric telescopic rod 935 is fixedly connected to the inner wall of the protection box 5.
[0043] By pressing the switch of the electric telescopic rod 935 , the power of the electric telescopic rod 935 can be turned on. The electric telescopic rod 935 drives the rack 934 to rotate, thereby driving the ring gear 933 to rotate and adjust the position of the ring gear 933 .
[0044] Embodiment 4:
[0045] See also Figure 5 A square groove 811 is provided inside the hollow cylinder 81 , a square plate 821 is fixed on the top of the movable rod 82 , and the square plate 821 is movably installed inside the square groove 811 .
[0046] The square plate 821 can move up and down inside the square groove 811 , and the design of the square plate 821 and the square groove 811 enables the hollow cylinder 81 and the movable rod 82 to rotate simultaneously, and the movable rod 82 can move up and down along the hollow cylinder 81 .
