Dredging device for water conservancy project

Abstract

The desilting device comprises a high-pressure water pipe used for desilting a river channel and a high-pressure spray head arranged at one end of the high-pressure water pipe and used for impacting sludge, a waistband is arranged on the outer side of the high-pressure water pipe, a first side plate and a second side plate are arranged on the two sides of the waistband correspondingly, and a connecting plate is arranged on the outer side of the second side plate; according to the desilting device for the water conservancy project, the waistband is fixed to the waist of a worker, so that on one hand, a high-pressure water pipe is supported by a certain force through the supporting mechanism arranged on the desilting device, and on the other hand, the high-pressure water pipe is supported by a certain force through the supporting mechanism arranged on the desilting device for the water conservancy project; and on the other hand, the pressing and pulling mechanism is arranged on the other side of the waistband, so that the part, close to a worker, of the water pipe can be pressed, and the phenomenon that the high-pressure water pipe moves disorderly due to large impact force of the high-pressure water pipe is prevented.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a dredging device for hydraulic engineering. Background technique [0002] my country's water conservancy projects have developed very rapidly in recent years, laying the foundation for my country's economic construction and development. At present, with the progress of urbanization, the construction of river courses in urban development has gradually become the key. A complete set of river treatment projects needs to be linked from the planning of relevant departments, to river treatment, improvement of sewage supporting facilities, and then to the construction of a good river water ecosystem. Therefore, a good river management project can not only resolve the problems that may arise in the process of river management in advance, but also promote the sustainable development of society and provide a positive impact on the protection of the water resources environme...

AI Technical Summary

Problems solved by technology

[0004] In the process of clearing river silt, two methods are usually used for dredging, one is dredging by excavating, and for narrower rivers, because the river has a certain slope and its If the bottom is narrow, the method of manual dredging is usually adopted: that is, manually hold a high-pressure water pipe, and at the same time, one end of the high-pressure water pipe is connected to a high-pressure nozzle. At the same time, in order to prevent a section of high-pressure water pipe close to the high-pressure nozzle from moving, it is necessary to manually fix it with feet, that is, to fix a section of the water pipe in the river channel by stepping on it. However, due to the diameter of the high-pressure water pipe itself Larger, the high-pressure water flowing inside it makes the high-pressure water pipe have a strong impact, making it difficult to fix, and at the same time, a large amount of silt is attached to the pipe, resulting in a relatively smooth surface. When artificial feet are stepped on, on the one hand, there will still be pipe The phenomenon of scurrying in the silt will lead to unstable standing during manual dredging. On the other hand, the attention of manual dredging will be distracted, which will affect the efficiency of river dredging.
