[0052] It should be noted that in use, the pipeline dredging robot is placed entirely inside the pipeline 100, so that the propulsion unit 1 is supported inside the pipeline 100, the forward cleaning assembly 21 and the reverse cleaning assembly 22 are tightly attached to the inner wall of the pipeline 100 and rotate synchronously in opposite directions, so that the sludge adhering to the inner wall of the pipeline 100 is scraped off by the forward cleaning assembly 21 and the reverse cleaning assembly 22, thereby achieving the effect of completely cleaning the sludge adhering to the inner wall of the pipeline 100 without cleaning dead angles.

[0053] As an improvement, as shown in Figures 1-3 , the propulsion unit 1 comprises:

[0058] The guide rod 15 is connected to one end of the bracket 10.

[0059] The push block 14 is slidably sleeved outside the guide rod 15.

[0060] The jacking spring 16 is sleeved outside the guide rod 15 and is used to jacking the top rod 12 through the push block 14.

[0062] A driving motor 211 is installed inside the propelling unit 1.

[0063] A driving shaft 212 is rotatably connected to one end of the driving motor 211.

[0064] A transmission mechanism 213 is arranged outside the driving shaft 212, and is used for rotating the inner wall of the pipe piece 100 in a forward direction.

[0065] Further, as shown, Figures 4-5 the transmission mechanism 213 comprises:

[0066] A transmission gear 2131 is fixedly sleeved outside the driving shaft 212, and a mounting base 21321 is sleeved outside the driving shaft 212, and the mounting base 21321 is fixedly connected to one end of the propelling unit 1.

[0067] A reversing gear 2132 is engaged with the outside of the transmission gear 2131, and one end of the reversing gear 2132 is rotatably connected to the inside of the mounting base 21321.

[0068] An inner tooth ring 2133 is engaged with the reversing gear 2132.

[0069] Forward cleaning teeth 2134 are arranged outside the inner tooth ring 2133, and are used for cleaning the sludge adhered to the inner wall of the pipe piece 100 by rotating in a forward direction.

[0070] Further, the forward cleaning teeth 2134 are arranged at equal angles outside the first scraping groove 21341, and are used for scraping the sludge adhered to the inner wall of the pipe piece 100.

[0071] The bottom of the first scraping groove 21341 is provided with a first guide surface 21342, which is used for guiding the sludge accumulated in the first scraping groove 21341 in a timely manner.

[0072] In addition, as shown, Figures 6-7 the reverse cleaning assembly 22 comprises:

[0073] Reverse cleaning teeth 221 are connected to one end of the driving shaft 212.

[0074] A second scraping groove 222 is arranged at equal angles outside the reverse cleaning teeth 221, and the opening direction of the second scraping groove 222 is opposite to that of the first scraping groove 21341, and is used for maintaining the force balance between the forward cleaning assembly 21 and the reverse cleaning assembly 22 when the rotating directions of the forward cleaning teeth 2134 and the reverse cleaning teeth 221 are opposite.

[0075] The second guide surface 223 is arranged at the bottom of the second scraping opening 222 and is used for guiding the accumulated sludge in the second scraping opening 222 out of the second scraping opening 222 in time.

[0076] It should be noted that, in the process of placing the pipeline dredging robot into the pipeline 100, the plurality of driving wheels 13 are simultaneously pressed downward, the driving wheels 13 drive the jacks 12 to rotate around the supports 10, the jacks 12 drive the push blocks 14 to move along the guide rods 15 and compress the compression springs 16, so that the periphery of the plurality of driving wheels 13 is smaller than the inner diameter of the pipeline 100, and then the pipeline dredging robot is placed into the pipeline 100, the driving wheels 13 are released, and under the pushing force of the compression springs 16 on the push blocks 14, the push blocks 14 drive the driving wheels 13 to be tightly pressed against the inner wall of the pipeline 100 through the jacks 12, and under the action of the plurality of driving wheels 13 being tightly pressed against the inner wall of the pipeline 100, the pipeline dredging robot can be stably installed in the pipeline 100;

[0077] Subsequently, water is sprayed along the inside of the pipeline 100 by using a water gun, the motors on the sides of the driving wheels 13 and the driving motor 211 are started, the motors drive the driving wheels 13 to move along the extension direction of the pipeline 100, so that the dredging unit 2 also moves continuously along the extension direction of the pipeline 100, at the same time, the driving motor 211 drives the reverse cleaning teeth 221 to rotate through the driving shaft 212, and the reverse cleaning teeth 221 continuously scrape the sludge adhered to the inner wall of the pipeline 100 through the second scraping opening 222, so that the sludge adhered to the inner wall of the pipeline 100 can be scraped without dead angle;

[0078] As shown in Figures 6-7 for the sludge gathered in the second scraping opening 222 after being scraped, the sludge scraped first is pushed out of the second scraping opening 222 by the sludge scraped later along the second guide surface 223 and falls to the bottom of the pipeline 100, and finally is taken out of the pipeline 100 by the water sprayed along the pipeline 100, so that the sludge in the second scraping opening 222 can be guided out in time, and the sludge scraped by the second scraping opening 222 is prevented from being hindered;

[0079] As shown in Figures 4-6As shown, while the driving shaft 212 drives the reverse cleaning tooth 221 to rotate reversely, the driving shaft 212 also synchronously drives the inner tooth ring 2133 to rotate through the reversing gear 2132, the inner tooth ring 2133 drives the forward cleaning tooth 2134 to rotate forwardly, and the forward cleaning tooth 2134 drives the first scraping opening 21341 to scrape the silt on the inner wall of the pipeline piece 100 for the second time. In this way, the inner wall of the pipeline piece 100 cannot be further cleaned completely, and for some parts that are firmly adhered to the inner wall of the pipeline piece 100, if only the reverse cleaning tooth 221 is used to scrape and clean, the silt will have a large resistance to the reverse cleaning tooth 221, which will cause the driving wheel 13 to slide circumferentially relative to the inner wall of the pipeline piece 100, and thus the dredging cannot continue. The forward cleaning tooth 2134 and the reverse cleaning tooth 221 are arranged to rotate reversely synchronously, so that the silt at the firmly adhered part of the inner wall of the pipeline piece 100 can be cleaned synchronously, the resistance of the silt to the forward cleaning tooth 2134 and the reverse cleaning tooth 221 is opposite, the entire pipeline dredging robot can be balanced as much as possible, and the effect that the pipeline dredging robot slides sideways when scraping the silt at the firmly adhered part can be effectively avoided.
