AI Technical Summary

Technical Problem

The traditional twisted suction dredging device has blind spots when dealing with special-shaped areas such as river corners and bottoms of bridge piers. The reel and suction system are prone to jamming large-sized stones, resulting in overload and shutdown of equipment and increasing the workload of personnel.

Method used

A water conservancy project silting device was designed. The rotary frame and side reamer bracket were driven to move around the circumference of the main mud conveying pump through a telescopic cylinder, expanding the crushing range of the reamer rotating head, and changing the spacing between the side reamer bracket and the main mud conveying pump, reducing the risk of stuck stones. At the same time, an external rotary cleaning rack was equipped to scrape away silt and shear debris on the surface of the filter mesh to ensure smooth equipment.

Benefits of technology

It improves the dredging efficiency in blind spots such as bridge pier and river corners, reduces equipment downtime, reduces workload for personnel, improves dredging efficiency and mud solids content, expands the operating space, and facilitates maintenance.

Abstract

The invention provides a hydraulic engineering desilting device convenient to clean, and relates to the technical field of hydraulic engineering desilting, the hydraulic engineering desilting device convenient to clean comprises a main supporting frame, a main slurry conveying pump, side reamer supports and a side connecting frame, the lower portion of the main supporting frame is fixedly connected with the main slurry conveying pump, and the side reamer supports are arranged on the two sides of the main supporting frame; the upper portion of the side reamer support is in axial sliding connection with the side connecting frame, the upper portion of the main supporting frame is rotationally connected with a lower connecting rotating frame in the circumferential direction, the main supporting frame is fixedly connected with an upper sliding groove disc above the lower connecting rotating frame, and outer arc-shaped sliding grooves are formed in the two sides of the upper sliding groove disc. The main supporting frame is rotationally connected with an upper connecting rotating frame in the circumferential direction above the upper sliding groove disc. The distance between the side reamer support and the main slurry conveying pump is changed, the situation that machine halt is caused due to the fact that stones are clamped between the main slurry conveying pump and the reamer rotating head is reduced, and the problem that due to the design of the fixed distance between the reamer and the suction opening, the stones with the large particle size are prone to being clamped between the reamer and the suction opening, and equipment overload machine halt is caused is solved.
