Description

Technical Field

[0001] The utility model relates to the technical field of silt removal devices, in particular to a silt removal device for a water conservancy project pipeline. Background Art

[0002] In the prior art, after a long period of use, a large amount of silt will adhere to the inner wall of the water conservancy project pipeline. If the silt is not removed in time, the inner diameter of the pipeline will become smaller. When the city faces heavy rainfall, the smaller pipe diameter will cause a smaller water flow, resulting in poor drainage of urban roads.

[0003] After searching, the Chinese patent application No. 202323006666.1 discloses a pipeline dredging device for water conservancy projects, including: a driving mechanism; a transmission member; a traveling mechanism, wherein the driving mechanism has multiple traveling mechanisms distributed in an annular manner, and the traveling mechanism is connected to the driving mechanism through a transmission member, and the transmission member is retractable; a dredging mechanism, wherein the dredging mechanism is provided with multiple ones and distributed in an annular manner, and the dredging mechanism is connected to the driving mechanism through a transmission member; adjusting the spacing between the dredging mechanism and the driving mechanism so as to adjust the dredging mechanism so that the dredging mechanism can fit on the inner wall of different pipelines, and through the telescopic adjustment of the transmission member, the traveling mechanism can fit on the inner wall of pipelines with different diameters, and the driving mechanism drives the traveling mechanism so that the dredging device moves along the pipeline, and in this process, the inner wall of the pipeline can be cleaned in a rotating manner by the rotating and moving dredging mechanism, so as to improve the cleaning effect of the inner wall of the pipeline.

[0004] The above patent has the following shortcomings: the device drives the moving mechanism through the driving mechanism so that the dredging device moves along the pipeline, and in this process, the inner wall of the pipeline can be cleaned in a rotating manner through the rotating and moving dredging mechanism; however, the pipelines of water conservancy projects are generally prefabricated concrete pipelines with a high inner wall roughness, and silt is generally deposited at the bottom of the inner wall of the pipeline. The use of a rotating dredging mechanism can easily cover the inner wall of the pipeline with silt. Although the amount of silt inside the pipeline is reduced, the dredging effect is relatively poor.
