self-propelled dredging vessel

Abstract

The invention discloses manual canal dredging equipment suitable for Yellow River diversion project and south-to-north water diversion project, and particularly a self-propelled dredging ship. The dredging ship is provided with a self-propelled dredging twisting and sucking head in connection with both a dredging pump and a water injection pump; the water injection pump is utilized to provide motive power to the twisting and sucking head, and the dredging pump is utilized to suck sludge, so that dredging of the canal is finished; the twisting and sucking head comprises hydraulically driven sludge twisting impellers which are arranged in a horizontally arranged volute; water inlet pipes for driving the impellers are arranged at the periphery of the volute; a sludge suction hole is formed in the center of the impellers and is communicated with a sludge suction pipe port which is located at the middle part of one side of the volute; one side of the periphery of the volute, which is opposite to the water inlet pipes, is provided with a sludge inlet; the sludge inlet enables the impellers to be exposed out of the volute, so that convenience is brought to the sludge mixing and the sludge suction of the sludge suction hole in the center of the impellers. The self-propelled canal dredging ship has a simple structure, a small number of moving parts, reliable operation, low energy consumption, high efficiency, a self-propelling function, strong adaptability, wide popularization and application foreground, and very remarkable social and economic benefits.

Description

technical field [0001] The invention discloses an artificial canal dredging equipment suitable for water diversion from the Yellow River and south-to-north water diversion projects, in particular to a self-propelled canal dredging ship. Background technique [0002] The history of water diversion from the Yellow River or South-to-North Water Diversion Project is not long, and a large part of the canals are large and medium-sized canals dug manually. There are few dredging machinery and equipment specially used for these canals, and the existing dredging machinery for rivers, lakes and ponds is generally used for their dredging operations. For example, the SLQY-30 amphibious dredger has dual characteristics of single-bucket hydraulic excavation for land and water excavation. The machine uses a flat-bottomed boat as the body, side pontoons increase buoyancy, and is equipped with 4 outriggers with swamp wheels controlled by hydraulic cylinders, which can operate synchronously ...

AI Technical Summary

Problems solved by technology

The above-mentioned existing dredging machinery and equipment have their own specialties, but they are not very suitable for dredging operations in artificial canals of the Yellow River Water Diversion Project or the South-to-North Water Diversion Project
