Technical Field

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

[0002] River desilting is a crucial water conservancy project, designed to remove sediment from the riverbed to restore and improve its flood-carrying capacity, water resource efficiency, and ecological environment. Numerous factors must be considered during river desilting. Detailed surveys and planning must be conducted to understand the riverbed's sedimentation, topography, and surrounding environment. Desilting typically involves extraction.

[0003] Since the extracted silt will be discharged on both sides of the river through pipes, and since the pipe heads are mostly placed in one place when discharging silt, this will cause the silt to accumulate in one place, which will affect the subsequent discharge of silt, making it inconvenient to discharge a large amount of silt; therefore, a river silt clearing device for water conservancy projects is proposed to address the above problems. Utility Model Content

[0009] Preferably, the rotating rod is located above the tube head and is rotated to penetrate the upper surface of the mounting frame. A gear is fixed to one end of the rotating rod that penetrates the outside, and the rack is engaged with the gear caliper.

[0010] Preferably, a bearing seat is fixed at one end of the installation groove, and a screw is rotatably installed in the installation groove through the bearing seat, and the screw rotates through the slider and is threadedly connected to it.

[0011] Preferably, the other end of the screw is rotated to penetrate the surface of one end of the mounting bar, and a motor for driving the screw is fixedly mounted on the surface of the one end of the mounting bar.

[0012] The utility model is beneficial in that:

[0013] 1. The utility model installs the installation frame to one side of the river channel through the support. When extracting silt, the pipeline is first connected to the pipe head. When discharging silt from the pipe head, the adjusting mechanism on the installation bar can be used to drive the rotating rod to rotate to control the pipe head to swing back and forth, thereby increasing the discharge and accumulation range of the silt, preventing the silt from accumulating in one place, and facilitating the accumulation of a large amount of silt.

[0014] 2. The utility model can rotate the worm by turning the knob, and when the worm rotates, it drives the worm gear to rotate. The rotation of the worm gear drives the adjusting rod to rotate, so that the angle of the tube head can be adjusted. At the same time, under the self-locking action of the worm gear transmission mechanism, it can be positioned after adjustment. The worm is installed on a set of pillars through the side plate, thereby achieving the purpose of driving the worm gear to rotate and adjust. By driving the slider to slide, the slider will drive the rack to move together when it slides, and the rack will drive the rotating rod to rotate when it moves, so as to adjust the tube head.
