[0002] In water conservancy construction, in order to resist the invasion of floods, people usually build dams to block the water flow. The water flow will carry impurities such as mud and sand, which will accumulate at the dam over time, causing the riverbed at the dam to rise, and ultimately affecting the barrier effect of the dam. Therefore, it is necessary to dredge the riverbed.

[0003] An existing anti-silt accumulation device for construction of water conservancy and hydropower projects can refer to the utility model patent with Chinese patent publication number CN217781879U. It is specifically a anti-silt accumulation device for construction of water conservancy and hydropower projects, including a silt cleaning cylinder, a loading disc is provided at the rear end of the silt cleaning cylinder, a loading plate is provided at the front end of the silt cleaning cylinder, a silt cleaning auger rod is rotatably installed between the loading disc and the loading plate, a silt discharge pipe is provided on the rear lower side of the silt cleaning cylinder, and a silt suction component is provided on the front side of the silt cleaning cylinder.

[0004] However, during the actual use of the device, it was found that although the device can change the angle of the silt suction pipe, thereby making the silt suction effect of the silt suction pipe better, the mixture of silt and water sucked out by the silt suction pipe will increase the weight during transportation when cleaning and transferring these mixtures, and cause water pollution along the way. Therefore, the present application provides a dredging device for water conservancy construction to meet the needs. Utility Model Content
