Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, in particular to an environmentally friendly river channel desilting device for water conservancy construction. Background Art

[0002] River dredging generally refers to the management of rivers, which belongs to water conservancy projects. Through mechanical equipment, the silt deposited on the bottom of the river is blown and stirred into turbid water, which flows away with the river water, thereby playing a role in dredging. The dredging mainly adopts the construction method of manual cleaning combined with mechanical transportation and unloading. Application No. 202120731910.2 discloses an environmentally friendly river dredging device for water conservancy construction, including a top cover, a motor box is provided on the bottom outer surface of the top cover, and electric telescopic rods are provided on both sides of the motor box and the top cover. A support frame is provided on the outside of the corresponding electric telescopic rod, a threaded rod is provided inside the support frame, and a slider is provided on the outside of the threaded rod and located on the inside of the support frame, and an insert is provided on the bottom outer surface of the motor box, and a rotating rod is provided inside the insert and located on the bottom outer surface of the motor box. A propeller is provided on the outer surface of the rotating rod, and storage boxes are provided on both sides of the insert and located on the bottom outer surface of the electric telescopic rod.

[0003] However, this device relies on two electric motors to simultaneously rotate the threaded rod to drive the propeller to rise and fall to clear the silt. This method not only leads to excessively high equipment costs for the entire device, but also there is a problem of the two motors running out of sync, which may cause the entire device to get stuck and fail to operate smoothly.

[0004] Therefore, we propose an environmentally friendly river channel desilting device for water conservancy construction. Utility Model Content
