[0032] The following describes the steps of using the urban sewer dredging device in conjunction with FIG. 1 to FIG. 5 in detail:

[0033] Initially, the telescopic shaft 16 is contracted into the telescopic cavity 15, and the lower end of the push block 29 abuts against the limiting block 39. At this time, the compression spring 28 is stretched, and the second bevel gear 23 meshes with the first bevel gear 13, and the spline sleeve 27 is not connected to the rotating shaft 40, the telescopic rod 68 is contracted in the telescopic groove 67, and the telescopic spring 72 is in a compressed state.

[0034] In use, the mounting block 10 is lowered to the desired position in the sewer by the rope 11, and the power motor 24 is operated to drive the driving gear 25 to rotate, and the second bevel gear 23 drives the first bevel gear 13 to rotate, thereby causing the two-way screw 14 to rotate, the telescopic shaft 16 moves backwards, and the abutting block 18 is closely attached to the inner wall of the sewage pipe, so that the mounting block 10 is fixedly installed in the sewer;

[0035] Thereafter, the driving motor 32 operates to drive the first gear 33 to rotate, so that the second gear 34 drives the threaded shaft 35 to rotate. Under the action of the limiting block 39, the drill shaft 36 is lowered, so that the filtering rotating rod 64 is located at the debris congested position. On the lower side, the smashing blade 62 is wrapped by the congested debris. At this time, the lowering of the limiting block 39 causes the pushing block 29 to descend, and the power block 20 is lowered, so that the second bevel gear 23 is separated from the first bevel gear 13. And the spline sleeve 27 is splined to the rotating shaft 40;

[0036] When the filter 71 is installed, when the power motor 24 is operated to rotate the rotating shaft 40, the six-sided cylinder 54 is lowered, so that the curved rack 65 drives the filter rotating rod 64 to rotate, so that the extending block 69 drives the filter 71 to rotate into the receiving cavity. 56 outside, when the filter rotating rod 64 is rotated to the horizontal position, the filter 71 is fully deployed, and during the rotation of the rotating shaft 40, the driving gear 45 is rotated, and the third bevel gear 48 is rotated, and the winding pulley is rotated by the transmission belt 51. When the rotation 80 is performed, the pull cord 66 is released, and the telescopic rod 68 is slid away from the side away from the curved rack 65 by the elastic restoring force of the telescopic spring 72, so that the extension block 69 is fitted to the inner wall of the sewage pipe. Then, the expanded area of the filter 71 is matched with the inner diameter of the sewer;

[0037] When the dredging is unblocked, the rotating motor 60 rotates to drive the spur gear 59 to rotate, so that the outer rotating cylinder 37 and the inner rotating cylinder 61 rotate, and the pulverizing knife 62 on the rotating knives can stir and crush the congested garbage or sludge. Therefore, the impurities are dispersed, and then, high-pressure water is injected into the sewer, and the crushed congested materials are washed away, and the fluid waste or the flowing sludge flows downward to the drainage system, and the solid waste is filtered and collected through the filter 71. Avoid being washed by high pressure water to the next sewer to cause blockage;

[0038] During the collection, when the driving motor 32 rotates in the reverse direction, the drill shaft 36 drives the garbage on the filter net 71 to rise, and when the drill shaft 36 rises to the initial position, the limiting block 39 pushes the push block 29 to rise, and the second bevel gear 23 and the second bevel gear 23 When the first bevel gear 13 is engaged and the spline sleeve 27 is disengaged from the rotating shaft 40, the power motor 24 operates to drive the second bevel gear 23 to rotate, and the bidirectional screw 14 rotates, so that the telescopic shafts 16 are close to each other, thereby mounting the mounting block 10 with The sewer is separated, the rope 11 is wound, and the mounting block 10 is pulled up to the ground, so that the solid waste in the filter 71 is taken out and collected.

[0039] The invention has the beneficial effects that the small volume of the invention can be directly placed in the sewer, fixedly installed by the telescopic fixing device and the sewer, and is suitable for use in sewers of different inner diameter ranges and depth ranges, and is crushed during the dredging process. The device smashes the clogged debris and the stuck sludge in the sewer, disperses between them, facilitates the subsequent high-pressure water scouring, clears the dredging speed, saves the water source, and the solid waste after the crushing is filtered through the filter. The collection can ensure the smooth flow of the sewer. The device has high automation, high efficiency, and safe operation.

[0040] In the above manner, those skilled in the art can make various changes depending on the mode of operation within the scope of the present invention.
