Dredger of improved structure

Abstract

The invention provides a dredger of an improved structure and belongs to the technical field of ships. The dredger of the improved structure comprises a ship body and a mud delivery pipe. A mud bin is arranged inside the ship body, and an energy dissipation tank is arranged in the mud bin. Two mud outlets are formed in the side wall of the energy dissipation tank. A fixing rack is hinged to the bow portion of the ship body. A dredge pump is arranged on the fixing rack. An inlet of the dredge pump communicates with one end of a dredge pipe, and an outlet of the dredge pump is connected with one end of a mud discharging pipe. The other end of the mud discharging pipe communicates with the interior of the energy dissipation tank. One end of the mud delivery pipe is a free end, and the other end of the mud delivery pipe is connected with one of the mud outlets in the energy dissipation tank. The mud delivery pipe is sleeved with a plurality of floating bodies with buoyancy in the axial direction, and the floating bodies are in clearance fit with the mud delivery pipe. The mud delivery pipe is made of a non-magnetic material. Each floating body is internally provided with a cavity, and electromagnets are arranged in each cavity and located at the two ends of the corresponding floating body. A limiting block is further arranged at the free end of the mud delivery pipe. The dredger of the improved structure has the advantage that the space of the mud bin can be fully utilized through the mud delivery pipe.

Description

technical field [0001] The invention belongs to the technical field of ships and relates to a dredger with an improved structure. Background technique [0002] The task of the dredger is to carry out underwater sand construction, specifically: digging deep, widening and cleaning existing channels and ports; excavating new channels, ports and canals; dredging piers, docks, locks and other water It is a sharp tool for blowing sand and reclamation, such as the foundation trench of industrial buildings and throwing the excavated sand into the deep sea or dredging and filling in land depressions to make fields. [0003] The cutter suction dredger extends the suction pipe to the surface of the underwater mud layer from the side or stern of the ship, and starts the suction pump in the cabin to suck, transport, load and unload the river bottom sediment to the transport ship or directly to the shore; Due to the deposition and compaction of the river bottom sediment layer, it is not ...

AI Technical Summary

Problems solved by technology

[0004] The current dredger pumps up the sediment and discharges the sediment into the mud tank through the mud discharge pipe. A large amount of sediment will accumulate near the outlet of the mud discharge pipe, while other positions in the mud tank will deposit less sediment. , resulting in the space in the mud tank not being fully utilized
