Description

Technical Field

[0001] The utility model belongs to the technical field of sludge cleaning, and in particular relates to a sludge cleaning device for a water conservancy concrete pipeline. Background Art

[0002] After a period of use, silt and other debris are easily deposited inside hydraulic concrete pipes, causing pipe blockage.

[0003] In the prior art, the silt inside the pipe is cleaned by using a silt cleaning device. For example, the Chinese utility model patent document with the authorization announcement number CN218990415U discloses a drainage pipe desilting device, which contacts the inside of the pipe through a rolling ball, has a small contact area, and has poor movement stability. The rolling ball is supported by an adjustment shaft, and by adjusting the length of the adjustment shaft, the rolling ball can be in close contact with the inner wall of different pipe diameters. However, once the adjustment shaft is adjusted, it provides rigid support for the rolling ball, and the inside of the concrete pipe interface is uneven, which easily causes the rolling ball to move poorly.

[0004] Therefore, it is necessary to design a sludge cleaning device for a hydraulic concrete pipe that can move smoothly and stably with the inside of the pipe to solve the technical problems currently faced. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a sludge cleaning device for a hydraulic concrete pipe which can move stably and smoothly inside the pipe.

[0007] A sliding section is arranged on the outer side of the end of the waterproof shell away from the dredging cone head, the slip ring is slidably mounted on the outer side of the sliding section, an adjusting ring is arranged on the outer side of the sliding section away from the dredging cone head, and a spring is mounted on the outer side of the sliding section between the adjusting ring and the slip ring.

[0008] A threaded section is arranged on the outer side of one end of the sliding section away from the dredging cone head, and the adjusting ring is threadedly connected with the threaded section.

[0009] A ring plate is fixedly arranged on the outer side of one corresponding end between the slip ring and the adjustment ring, and the ring plate corresponds to the end of the spring.

[0010] The walking wheel group comprises a support rod, and pulleys are rotatably arranged on both sides of the two ends of the support rod, and one end of the support connecting rod which is away from the waterproof shell is hinged to the support rod.

[0011] The driving component is a reduction motor drivingly connected to the dredging cone head.

[0012] Beneficial effects of the utility model:

[0013] (1) In the present invention, the walking wheel groups around the waterproof housing are in contact with the inner wall of the pipeline, which can increase the contact area with the pipeline and improve the stability of the movement of the device;

[0014] (2) The supporting connecting rod, adjusting connecting rod and elastic supporting slip ring provide elastic support for the walking wheel group along the radial direction of the waterproof shell, keeping the walking wheel group in close contact with the inner wall of the pipe. At the same time, when encountering the uneven pipe wall environment inside the pipe, it can provide a certain elastic buffer to ensure its smooth movement. BRIEF DESCRIPTION OF THE DRAWINGS
