Trailing suction device for dredger

Abstract

The invention provides a trailing suction device for a dredger. The trailing suction device for the dredger comprises a trailing casing which is defined by side plates and a rear cover which is arranged at the rear end; the silt inlet is reserved at the front end of the trailing casing; the silt outlet is formed under the rear end of the trailing casing and connected with a silt discharging pipe; a plurality of vertical partition plates are arranged in the trailing casing; the outer side of the trailing casing is provided with a water supply pipe which is connected with a high-pressure water gun; the water supply pipe is connected with a plurality of water distributive pipes; the ends of the water distributive pipes are located under the trailing casing. The inner side of the trailing casing is provided with the partition plates and accordingly the strength of the trailing casing is improved, silt can enter into between the adjacent partition plates, and accordingly the silt sucked into the inner chamber of the trailing casing can be uniform to the greatest extent. The water supply pipe is connected with a high pressure water supply device arranged on the ship through a pipeline, a water source of the water supply device is the sea water or the river water and the like from the operational area, the high pressure water can be ejected out of the water distributive pipes during water supply, the silt deposited at the trailing suction position can be smashed due to the fact that the distributive pipes are connected with the trailing suction device, and the silt can be mixed with the water to form loose mud which can be sucked into a mud pump conveniently.

Description

technical field [0001] The invention relates to a dredging ship component, in particular to a dredging ship raking device. Background technique [0002] Desilting treatment is required during the construction of ports and rivers or in normal times, and dredging ships are mainly used for operations. The dredging ship is equipped with equipment such as a mud pump mechanism and a winch mechanism. The suction port of the mud pump is connected with a suction device through a pipeline. At the same time, the ship is relatively fixed by the anchor, and the mud pump is used to suck out the underwater mud. The mud first enters the suction device and is discharged through the pipeline. The rake suction device is the entrance of the silt. The existing rake suction device is just a shell, and the underwater moving position is realized by dragging and dragging by the winch mechanism. The current raking suction device enters uneven sludge during operation, and the shell strength is poor,...

AI Technical Summary

Problems solved by technology

The current raking suction device enters uneven sludge during operation, and the shell strength is poor, and it is easy to deform after being stressed. More importantly, the sludge will have a certain hardness after a long time of deposition, and it cannot be completely sucked and removed. Sometimes it needs to be operated. Personnel dive into the water and use hand-held air compressors to carry out local dredging operations, which is time-consuming, laborious, low work efficiency, and poor safety
