The present invention relates to an underwater sediment removing device, which is a sediment removing device (1) for preventing the contamination of water by filtering after sucking and collecting sediment accumulated on the bed of a lake or a river. The underwater sediment removing device comprises: a boat unit (10) which moves on the surface of water; a lift unit (20) which is connected with the lower part of the boat unit (10) and whose length is variable; a caterpillar unit (30) which is connected with the lower part of the lift unit (20); a sediment collecting unit (40) which is connected with one side of the lift unit (20) in order to collect sediment accumulated on the water bed; a discharge pipe unit (50) which is connected with the sediment collecting unit (40); and a filter unit (60) which is connected with the discharge pipe unit (50). The underwater sediment removing device includes: a caterpillar which is seated on the water bed and moves in order to accurately move the sediment removing device connected with the lower part of a boat; a crossed rod type lift means which easily changes the height of the boat and the caterpillar depending on the depth of water; and a connection rotating bar which is connected by a hinge and rotates freely in order to prevent the damage to a connection unit due to the curved water bed. |
