[0003] In the patent publication CN219188014U, a water conservancy project pipeline cleaning device is disclosed, which drives the counterweight body through the driving mechanism on the outer side wall of the counterweight body, and the counterweight body can move with the scraping mechanism and the cleaning mechanism in the pipeline through the driving mechanism, and the scraping mechanism and the cleaning mechanism are driven to rotate through the rotating mechanism to clean the inner wall of the pipeline. The scraping mechanism is located upstream of the cleaning mechanism. In the cleaning process, the stubborn dirt on the inner wall is first scraped loose by the scraping mechanism, and then cleaned by the cleaning mechanism. The whole cleaning process is efficient, and workers do not need to enter the pipeline, reducing the risk of workers.

[0004] The cleaning brush of the cleaning assembly in the above-mentioned patent is attached to the inner wall of the pipeline through the elastic force of the first spring, and the scraping plate is attached to the inner wall of the pipeline in the same way. In actual application, it is found that the elastic force of the spring is fixed and suitable for a certain diameter of pipeline. When the diameter of the pipeline increases, the spring may not be able to provide enough pressure to make the cleaning brush tightly attached to the inner wall, resulting in incomplete cleaning.

[0005] Although different sizes of scraping discs can be selected according to the size of the pipeline in the above-mentioned patent, the hardness of the deposits in the pipeline may be different in the same diameter pipeline, and the harder deposits may need stronger pressure to clean. Therefore, a water conservancy project pipeline cleaning device is proposed. UTILITY MODEL CONTENTS

[0011] Specifically, a ball groove is formed in the limiting block, and a ball in contact with the second cavity is arranged in the ball groove.

[0012] Further, one end of the pull rope extending to the outer side of the fixed plate is fixed with a pull ring, and an outer contour of the pull ring is rectangular.

[0013] Specifically, an inner contour of the sliding groove is larger than an outer contour of the limiting block.

[0014] Further, a height of a top surface of the cleaning brush in a horizontal state is higher than a height of a top surface of the limiting rod.

[0016] The water conservancy project pipeline cleaning device has the following beneficial effects:

[0017] 1. The water conservancy project pipeline cleaning device drives the cleaning brush to the position of the inner wall of the pipeline by starting the second electric push rod, drives the eccentric block to rotate by pulling the pull rope through the pull ring, and then drives the rotating rod and the limiting block to rotate in turn through the eccentric block, the limiting block corresponds to the sliding groove, and under the elastic force of the compression spring, the mounting plate drives the cleaning brush to slide on the limiting rod, the cleaning brush tightly abuts against the inner wall of the pipeline, and when the pipeline of different sizes is targeted, the cleaning brush and the pipeline can maintain stable pressure.

[0018] 2. When the sediment in the pipeline is hard, the pipe cleaning device can be used to pull the rope by pulling the ring, so that the limit block no longer limits the mounting plate. Then, the cleaning brush, mounting plate, and pressure spring can be removed in sequence. Next, a pressure spring with stronger elasticity is put on the limit rod. The cleaning brush and mounting plate are reinserted into the limit rod and the replaced pressure spring is squeezed. Then, the ring is released. Under the action of the spring elasticity, the eccentric block will drive the rotating rod and the limit block to reset. The limit block limits the mounting plate again. This device makes it easy to replace the pressure spring according to the hardness of the sediment in the pipeline. Attached Figure Description
