Desilting structure and hydraulic engineering desilting device

Abstract

The invention discloses a desilting structure and a hydraulic engineering desilting device and belongs to the technical field of hydraulic engineering. The desilting structure comprises a bucket bodyand prodding claws. The bucket body comprises a feeding portion, a connecting portion and a silt storage portion which are connected in sequence. The bottom of the feeding portion is arranged obliquely. The bottom of the silt storage portion is arranged horizontally. The highest end position of the feeding portion and the silt storage portion are connected through the connecting portion. The prodding claws are fixed to a drum. The multiple prodding claws are distributed in the radial and circumferential directions of the drum. A gap exists between every two adjacent prodding claws. The prodding claws are each of an L-shaped structure. The outer edges of the prodding claws are opposite to the feeding portion. An impurity portion is arranged on the upper portion of the silt storage portion.An oblique partition plate is arranged between the impurity portion and the silt storage portion. The top end of the partition plate is opposite to the outer edges of the prodding claws. The desiltingstructure and the hydraulic engineering desilting device have the beneficial effects that when desilting is performed, silt is separated from stones, large-size impurities and the like inside, separated storage is achieved, the stones, large-size impurities and the like in the silt are prevented from damaging equipment or the device in the moving process, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a dredging structure and a dredging device for hydraulic engineering. Background technique [0002] A water conservancy project is a project built for the purpose of controlling and deploying natural surface water and groundwater to achieve the purpose of eliminating harm and increasing profits. Also known as water engineering. 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 flood disasters, and adjust and distribute water to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, embankments, spillways, sluice gates, water inlets, channels, ferries, rafts, fishways, etc., to achiev...

AI Technical Summary

Problems solved by technology

[0003] At present, the rivers in cities and towns are not treated in time due to the perennial sedimentation and silt, which leads to the scrapping of some water conservancy facilities. Once a flood occurs, there will be serious consequences, which brings great difficulty to the water conservancy project staff.

[0004] The existing dredging devices generally realize the treatment of sludge by suction, but because there are some stones and impurities in the sludge, it is easy to block the pipeline during suction, and in severe cases, the suction pump will be damaged.
