In general, sediments such as abandoned shells, rubbish, sludge, and soil are accumulated due to currents, typhoons, and sediments in the sea, rivers, and lakes. Since these sediments cause eutrophication, in the case of the ocean, red tide occurs and the aquatic ecosystem is destroyed.

In addition, the surface of the sea, rivers, lakes, etc. are suspended from foreign matter moving along the typhoon or algae, and the building and household waste from the land, such floating filth also causes eutrophication and adversely affect seafood production It also interferes with the safe operation of the ship and damages its aesthetics.

Accordingly, countries around the world are developing various devices for removing underwater sediment and floating surface, and at the same time, researching various solutions. However, the method of removing the floating surface of the water still remains at the level of technology that the worker removes by using the removal tool or the forceps by the removal tool while boarding the ship, and the method of removing the sediment in the water is also an underwater pump. B. The level of the conventional technology is being followed to inhale and remove foreign substances by using a robot.

For example, as a system for removing sediment in water, a dredging device configured to remove sediment by a conveyor is disclosed, as shown in Korean Patent Registration No. 10-1012750 filed by the present applicant, and registered in Korea.
