Equipment for improving loading efficiency of trailing suction hopper dredger

Abstract

The invention relates to equipment for improving the loading efficiency of a trailing suction hopper dredger. The equipment is arranged in a cabin of the dredger, is used for preventing silt from flowing out of an overflow cylinder in the cabin, and comprises air injection devices and lifting devices, each air injection device comprises an air pump, an air delivery hose and at least one bubble curtain generating pipe, each air delivery hose is communicated with the corresponding air pump and the corresponding bubble curtain generating pipes, the air outlet ends of the bubble curtain generatingpipes face the overflow cylinder, and the lifting devices are connected with the bubble curtain generating pipes in a one-to-one correspondence mode and can drive the bubble curtain generating pipesto ascend and descend. The equipment for improving the loading efficiency of the trailing suction hopper dredger has the following beneficial effects that the air pumps can generate a large number ofbubbles near an overflow pipe through the bubble curtain generating pipes to form a bubble curtain, and when water containing silt flows towards the overflow pipe, the bubbles prevent the silt from continuously moving along with water flow, so that the silt is left in the cabin, the water flows away from the overflow pipe, the silt loss at the overflow cylinder is greatly reduced, and the loadingefficiency of the dredger is effectively improved.

Description

technical field [0001] The invention relates to the technical field of dredgers, in particular to a device for improving the loading efficiency of a trailing suction dredger. Background technique [0002] The trailing suction dredger is a common equipment used in dredging construction. Its equipped rake head and hydraulic dredging device can excavate and transport the sediment, gravel and other materials on the riverbed or seabed into the cabin, and then remove the soil and gravel Move it to a suitable place to clear the river, widen the river bed, and improve the navigation capacity of the river. [0003] The sediment is excavated from the rake head and transported by the mud pump and pipeline, and then settles in the cabin. As an important link in dredging, the efficiency of loading directly affects the dredging output of the dredger. In the process of loading, the amount of mud Settlement is very critical. In the previous loading process, the mud entered the tank at a hi...

AI Technical Summary

Problems solved by technology

[0004] In view of this, it is necessary to provide a device for improving the loading efficiency of trailing suction dredgers, in order to solve the technical problem in the prior art that muddy water is easy to flow away from the overflow tank and reduce the loading efficiency
