The present invention relates to an underwater bottom soil removal system configured to be suitable for dispersing contaminants, sediments or trash at the bottom of water into high-pressure water streams and inhaling and transporting them to floating bodies such as ships and boats on the surface.

In the past, sediments such as pollutants or sediments that enter the sea, rivers, and lakes, destroy the ecosystem in the water, and in order to remove them, a suction pipe is generally placed on the sediment to remove the sediment by the suction force of the pump. Although there was a device for transporting on a vessel close to the ground or on the surface of the water, it was difficult to use due to the low sediment collection effect and efficiency. Another way to solve this is to use dredgers, but until now, dredgers developed for the purpose of mass dredging have been used to make large pits in the excavated floor, or to generate unnecessary excessive drilling work. In addition, secondary floats are generated by excavation work, and contaminants are diffused by algae, currents, etc., further contaminating the surrounding environment, which is a problem.

Moreover, these methods will not work unless there is an underwater obstacle, such as a cable, in the farm, unless the entire facility is moved or the obstacles are completely removed.

The water-based unit has a remote control device that controls the underwater device while checking the underwater work in real time by the CCD monitor.

The traveling device uses an endless track system in order to have a characteristic that can run on soft ground. In addition, this method consumes less power for driving and has a characteristic of not consuming extra energy to secure a magnetic position.

Uniform excavation work such as contaminants or sediments can be carried out to match the shape of the bottom surface, and the work is done in the closed space by attaching a carver to the excavation device, thus preventing the spread of contaminants held on the floor during excavation work. can do. In addition, since the bottom surface of the excavation work is flat, there is no need for a separate flat work like the existing excavation work, and the work content is monitored in real time, thereby improving the efficiency of the excavation work.
