Hydraulic engineering desilting device with stirring function and desilting method thereof

Abstract

The invention discloses a hydraulic engineering desilting device with a stirring function and a desilting method thereof. The desilting device comprises a fixed pipe and a fixed plate; a motor is mounted at the top end of the fixed pipe; an output end of the motor is fixedly connected with a shaft rod through a coupling; the bottom of the shaft rod is fixedly pinned with a stirring rod; a fixed sleeve is fixedly welded on the fixed plate; a connecting base is fixedly welded on one side of the fixed plate; the fixed pipe penetrates through the internal of the fixed sleeve; an impeller bin is arranged at the upper part of the fixed pipe; one side of the impeller bin is connected with a dirt discharge pipe through a flange; a dirt sucking cover is fixedly welded at the bottom end of the fixedpipe; and walking wheels are mounted on the two sides of the dirt sucking cover. The device uses the motor for driving the shaft rod to synchronously drive a stirring rod and an impeller to rotate, achieves multiple purposes by one machine, can be automatically adjusted according to the sludge depth to adapt to cleaning of sludge in different water depth places, and can realize flexible movementin areas through cooperation with movement of a desilting ship body to finish the sludge cleaning work in appointed areas.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering devices, in particular to a water conservancy dredging device with stirring function and a dredging method thereof. Background technique [0002] There are currently two main types of equipment used for dredging: one is a split hydraulic dredger, which is suitable for small and medium-sized dredging equipment; the other is a dredging ship, which belongs to large and medium-sized dredging equipment. The hydraulic desilting machine is composed of a bank clear water centrifugal pump and a mud pump with a buoy in the water. The role of the bank clear water pump is to flush and stir the dredging site with hydraulic power, so that the mud near the suction port of the mud pump will be in a suspended state, so that the mud pump can pump away the mud water (concentration ≤ 30%). The dredging ship equipment is composed of a mud pump installed on the ship and a mechanical agitator inst...

AI Technical Summary

Problems solved by technology

Existing problems: (1) Both the mud pump and the agitator have their own motors, which are heavy and need to be installed on the dredging ship, which is inconvenient to move and use flexibly, and is not conducive to miniaturization. It is only suitable for large-scale dredging sites

(2) High energy consumption

[0004] However, the above-mentioned scheme has the following defects in use: in the cleaning process, the dredging depth cannot be adjusted with the ups and downs of the silt, and the silt at a certain depth can only be cleaned, and the depth exceeds the depth of the detachable short pipe installed for the first time. After the total length, it will be difficult to meet the dredging requirements
