Title:
DREDGING DEVICE FOR HYDRAULIC ENGINEERING
Document Type and Number:
WIPO Patent Application WO/2022/052301
Kind Code:
A1
Abstract:
The present invention relates to the technical field of hydraulic engineering, and provides a dredging device for hydraulic engineering, comprising a machine body. One end of the machine body is movably connected to a water pipe, the lower part of the machine body is movably connected to a driving box, and the other end of the machine body is fixedly connected to a connecting block. The outer surface of one end of the connecting block is provided with a high-pressure spray head, and the side surface of the other end of the connecting block is movably connected to guide rods. According to the present invention, a guide mechanism is added on the side surface of the machine, such that when the machine carries out a dredging operation on a drainage pipeline, the orientation of guide wheels can be automatically changed according to the change of the extending length of the guide mechanism, the machine is automatically steered, and the situations that when conventional pipeline dredging devices carry out automatic dredging on the pipeline, due to pipeline bending, wall collisions and the like are generated during dredging of the machine are avoided. The dredging efficiency of the machine is guaranteed, the service life of the machine is prolonged, and the damage of dredging work to the inner wall of the pipeline is reduced.
