Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, and more specifically, to a river channel desilting device for water conservancy projects. Background Art
[0002] When a river is used for a long time, silt is easy to accumulate at the bottom of the river, thus affecting the normal operation of various functions such as flood control, irrigation and navigation. It is necessary to use dredging equipment to dredge the river at regular intervals. Most dredging devices use sewage pumps as a power source to extract silt. Although this dredging method can suck out the silt in the river, when discharging, the silt is not treated, so the silt is easy to be blocked inside the dredging device, resulting in difficulty in discharge; and most of the existing river dredging equipment does not have the function of cleaning the filter plate. Therefore, when the filter plate is used for a long time, the holes on the filter plate are easily blocked by impurities in the silt, which affects the subsequent dredging work. Utility Model Content
