Environment-friendly modular dredger

Abstract

The invention discloses an environment-friendly modular dredger. The dredger comprises a buoyant box module, a positioning pile system module, a bridge system module, a digging device module, a portal module, a supporting platform module, a power system module, a propelling system module, a living and control system module and a manipulation module. The environment-friendly modular dredger is convenient to transport by land and assemble and disassemble with the adoption of the standard functional modules and can operate after being transported to a designated lake and reservoir areas and assembled, and the standard modules can be used for series of vessels as required.

Description

technical field [0001] The invention relates to the technical field of environmental protection dredging, in particular to a modular environmental protection dredging ship, which is suitable for environmental protection dredging of rivers, lakes and reservoirs. Background technique [0002] After years of operation, lakes and reservoirs will gradually develop serious sedimentation, which greatly reduces the effective storage capacity of lakes and reservoirs and endangers the reservoir dam. At the same time, harmful pollutants in the sediment have formed an internal source of pollution to the water body. In order to solve the problem of siltation and internal source pollution in the reservoir area, it is necessary to use dredging ships and other dredging machinery for dredging. [0003] Compared with traditional dredging, environmental protection dredging of lakes and reservoirs has greater technical difficulties. At the same time, reservoir dredging has its own characteristi...

AI Technical Summary

Problems solved by technology

[0005] (2) In order to prevent under-excavation and over-excavation when removing pollutants, without damaging the original soil or mixing the sludge layer with the sediment, the excavation accuracy is high. Usually, the construction accuracy of environmental protection dredging is about 5-10cm, while The accuracy of engineering dredging is about 50cm, and traditional dredging equipment cannot meet the accuracy requirements

[0007] (4) Reservoirs are mostly located in inland and alpine valley areas, and traditional dredging equipment (such as cutter suction dredgers, trailing suction dredgers, etc.) cannot reach them, and dredging equipment can only be sent to designated construction sites by land transportation , so the weight and size of the dredging equipment are required to be as small and light as possible

[0008] (5) The water depths of different reservoirs and reservoir areas vary greatly, and the maximum water depth is relatively deep, which requires high adaptability to the excavation depth of dredging equipment

[0009] (6) The topographic conditions and sediment composition of the reservoir bottom are complex (such as polluted mud layer, coarse sand layer, pebbles, etc.), which requires high excavation equipment, and single excavation equipment is difficult to meet the construction requirements

Or carry out transformation on the basis of traditional ships, but it is difficult to solve the above technical difficulties
