[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0020] A sewage pipe dredging device, such as Figures 1-4 As shown, the device includes a cleaning device and a propulsion pipe 1. The cleaning device includes a scraper assembly 2 and a motor 3. The scraper assembly 2 is fixedly mounted on the output end of the motor 3. When the motor 3 is running, the scraper assembly 2 is driven to rotate and scrapes the inner wall of the pipe, thus forming the basic function of this sludge removal device. A water pipe is fixedly mounted on the propulsion pipe 1, and a front spray hole 4 and multiple rear spray holes 5 are opened. The front spray hole 4 faces the scraper assembly 2, and the rear spray holes 5 are opened on the side facing the water pipe. The front spray hole 4 and multiple rear spray holes 5 on the propulsion pipe 1 are designed to work on the same principle as a "water rat," with water flowing towards the depth of the pipe and both sides of the outlet, creating the effect of spraying out the accumulated debris. The scraper assembly 2 is equipped with an abutment strip 6, which is used to abut the scraper assembly 2 again after it has made initial contact with the sludge on the pipe wall. This prevents the scraper assembly 2 from cutting too deeply while also creating a second contact with the sludge on the pipe wall.
[0021] The scraper assembly 2 comprises a tapered cylinder 21, a first scraper 22 and a second scraper 23, a plurality of positioning pieces 24 are arranged on the tapered cylinder 21, the ends of the positioning pieces 24 away from the tapered cylinder 21 are rotationally connected with the first scraper 22, the end of the first scraper 22 away from the positioning pieces 24 is rotationally connected with the second scraper 23, the elastic ropes 25 are arranged between the positioning pieces 24 and the first scraper 22 and between the first scraper 22 and the second scraper 23, and the first scraper 22 and the second scraper 23 form a retracted state through the elastic ropes 25, which is the position in the initial state, when the motor 3 operates, the first scraper 22 and the second scraper 23 will be unfolded under the action of centrifugal force and swing towards the inner wall of the pipeline, so as to form scraping on the inner wall of the pipeline and achieve the cleaning effect, when the motor 3 gradually stops, the first scraper 22 and the second scraper 23 will be recovered and gradually return to the initial state when the centrifugal force is smaller than the pulling force of the elastic rope. Figure 1
[0022] The abutting strip 6 is fixedly arranged at the edge area of the second scraper 23, a plurality of convex edges are formed on the abutting strip 6, the convex edges are used to enhance the cleaning effect formed by the abutting and scraping of the second scraper 23 on the inner wall of the pipeline, and the centrifugal force formed by the second scraper 23 is also increased, so as to enhance the abutting force on the inner wall of the pipeline.
[0023] The rotating rod 8 is rotationally arranged on the advancing pipe 1, the elastic member is arranged between the rotating rod 8 and the advancing pipe 1, the end of the rotating rod 8 away from the advancing pipe 1 is rotationally arranged with the wheel 9, the elastic member is arranged as the clock spring 10, and the arrangement among the rotating rod 8, the wheel 9 and the clock spring 10 is used to support the height of the advancing pipe 1, support the advancing pipe 1 to extend into the pipeline to form the pushing, and reduce the moving resistance of the advancing pipe 1 in the pipeline.
[0024] The motor 3 is fixedly arranged with the electric wire, and the electric wire and the water pipe are arranged with the protective pipe 11, the arrangement of the protective pipe 11 forms the protection of the circuit and the water pipe, and the damage to the circuit and the water pipe is reduced to the maximum extent.
