Abstract

The invention aims to provide an ROV-based dredging device and method for a hectometer-level deep water environment. The ROV-based dredging device for the hectometer-level deep water environment comprises an ROV body, a three-dimensional panoramic sonar recognition system and an air lifting dredging system are carried on the ROV body, the ROV body can be fixed to the surface of a hydraulic structure, the three-dimensional panoramic sonar recognition system is used for scanning the underwater environment to determine the fixed position of the ROV body, and the air lifting dredging system is used for dredging the periphery of the fixed position of the ROV body. Compared with an existing dredging mode, the ROV-based dredging device for the hectometer-level deep water environment is lighter indesign, can be flexibly assembled and disassembled, and has certain help for deep water dredging work in a narrow space; and meanwhile, the advantages of underwater work of the ROV body can replace traditional manual diving dredging, the diving cost is reduced, and the life safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of underwater dredging, in particular to an ROV-based dredging device and method for a 100-meter deep water environment. Background technique [0002] Most of the rivers in our country have high sediment content. After many years of operation, reservoirs, culverts and river courses generally have different degrees of siltation. Serious siltation may even affect the normal work of hydraulic structures, such as gates that cannot be closed, river beds that are excessively lifted higher. At the same time, the deposited silt accumulates a large amount of pollutants, which are easily released into the water body over time to cause secondary pollution. Therefore, the silt cleaning work is related to the operation safety of hydraulic structures and the ecological safety of water environment, and is an important problem to be solved urgently in the operation and management of hydraulic structures. [0003] In recen...
