Description

Technical Field

[0001] The utility model relates to the technical field of dredging devices, in particular to a river channel dredging device for water conservancy construction. Background Art

[0002] Dredging engineering refers to the earthwork engineering carried out by underwater excavation with dredgers or other machines and manual labor to widen and deepen the water area. The trench design of dredging engineering should try to change the geometric boundary of the river flow, causing changes in the internal structure of the water flow, so that the newly formed water flow structure can not only ensure that the silt will no longer accumulate in the waterway, but also transport the silt entering the trench to the lower deep trench to maintain the stability of the waterway. Water conservancy projects are used to control and allocate natural surface water and groundwater, and are built for the purpose of eliminating harm and promoting benefits. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and disasters, and regulate and distribute water to meet the needs of people's lives and production for water resources. The existing river dredging and silt removal devices for water conservancy construction still have some defects, such as:

[0003] For example, a river dredging device with announcement number CN219137814U includes a dredging box, an inclined plate is fixedly connected to the dredging box, a guide plate is slidably connected to the inclined plate, a spring is fixedly connected between the inclined plate and the guide plate, a rack I is fixedly connected to the inclined plate, a fixed seat is fixedly connected to the inclined plate, a rack II is slidably connected to the fixed seat, a gear is rotatably connected to the fixed seat, both rack I and rack II are meshed with the gear, a marking tip is connected to rack II, the lower end of the guide plate is an arc surface, and also includes a vertical plate slidably connected to rack II, a threaded hole I is provided on the fixed seat, and the vertical plate can be fixed by screwing a bolt into the threaded hole I, so that hard silt, rocks or other solid obstacles at the bottom of the river can be avoided during the dredging process, and marks are left at corresponding positions on the river bank, which provides convenience for subsequent manual inspection.

[0004] The above technical solution has the following problems:

[0005] The river channel silt removal device is not provided with multiple anti-blocking mechanisms, so that the river channel silt removal device cannot prevent silt from blocking the inside of the device when in use, and the working efficiency is low and the use is not convenient enough;
