Embodiment 1

[0031] Example one, refer to the attached figure 1 , 2 , 3, 5.

[0032] A self-propelled cutter suction dredging device for water channels, which is characterized in that it comprises a volute 1, an impeller 5 is arranged in the volute, and a water inlet pipe 4 for pushing the impeller is arranged around the volute; a mud suction port is arranged in the center of the impeller, and The mud suction pipe port 2 in the center of one side of the shell is communicated, and a mud inlet is provided on the side of the periphery of the volute opposite to the water inlet pipe to expose the impeller to the volute.

[0033] The volute is in the shape of a flat truncated cone, the bottom 7 is in a closed state with the periphery of the volute, and the water inlet pipe 4 that pushes the impeller is smoothly and excessively connected along the tangent to the periphery of the volute 1;

[0034] The bottom 7 and the periphery of the volute are in a closed state, which means that the bottom of the volu...

Embodiment 2

[0043] Example two, refer to the attached figure 1 , 2 , 3, 4.

[0044] A self-propelled cutter suction dredging device for water channels, which is characterized in that it comprises a volute 1, an impeller 5 is arranged in the volute, and a water inlet pipe 4 for pushing the impeller is arranged around the volute; a mud suction port is arranged in the center of the impeller, and The mud suction pipe port 2 in the center of one side of the shell is communicated, and a mud inlet is provided on the side of the periphery of the volute opposite to the water inlet pipe to expose the impeller to the volute.

[0045] The volute is in the shape of a basin, the bottom and the periphery of the volute are in a semi-closed state, and the water inlet pipe pushing the impeller is smoothly and excessively connected along the tangent line of the volute circle;

[0046] The bottom 7 and the periphery of the volute are in a semi-closed state, which means that the part of the bottom of the volute near...

Embodiment 3

[0055] Example three, refer to the attached figure 1 , 2 , 3, 6.

[0056] A self-propelled canal dredging vessel includes a hull 10, power equipment and a mud conveying mechanism. It is characterized in that: a silt pump 13 and a water injection pump 11 are arranged on the dredging vessel, and the silt pump and the water injection pump are connected to a self-propelled cutter suction cleaning The silt suction device 16, said cutter suction dredging device includes a hydraulically driven dredged mud impeller 5 arranged in a flat volute 1, a water inlet pipe 4 pushing the impeller is arranged around the volute, and a mud suction port is formed in the center of the impeller, and The mud suction pipe port 2 in the middle of one side of the volute is connected, and a mud inlet is provided on the side opposite to the water inlet pipe 4 on the periphery of the volute. The mud inlet exposes the impeller to the volute, which is convenient for agitating the mud and the mud suction port in t...

Abstract

The invention discloses a self-propelled cutter suction desilting device and a driving method for artificial canals suitable for diversion of water from the Yellow River and diversion of water from the South to the North. The volute is equipped with a hydraulically driven mud-cutter impeller, and the water inlet pipe for driving the impeller is arranged around the volute, and a mud suction port is formed in the center of the impeller, which is connected with the mud suction pipe on one side of the volute, and the periphery of the volute is connected with the water inlet pipe. The mud inlet is set on the opposite side, and the water injection pump is used to input high-pressure water flow from the water inlet pipe installed in the volute, and the impeller in the volute is driven to rotate, and the silt at the bottom of the channel is mixed with water to form a slurry, and the mud suction port in the center of the impeller is used Sludge pump sucks out. It has simple structure, less moving parts, reliable operation, low energy consumption, high efficiency, self-propelled function and strong adaptability. It is used in conjunction with various dredging ships to solve the problem of dredging artificial canals in the Yellow River Water Diversion Project or the South-to-North Water Diversion Project. The professional subject of the assignment.

Description

Technical field [0001] The invention discloses an artificial water channel dredging device suitable for water diversion from the Yellow River and the South-to-North Water Diversion project, in particular a self-propelled cutter suction dredging device and a driving method. Background technique [0002] The history of water diversion from the Yellow River or the South-to-North Water Diversion Project is not long, and a large part of the canals are large and medium-sized channels excavated manually. There are very few dredging machinery and equipment dedicated to these water channels, and the existing river and lake dredging machinery is generally used for its dredging operations. For example, the SLQY-30 amphibious dredger has the dual characteristics of land-use single-bucket hydraulic excavation and water excavation. The machine uses a flat-bottomed boat as the body, with side pontoons to increase buoyancy, and is equipped with 4 outriggers with swamp wheels controlled by hydra...
