Referring to FIG. 9, when the first propellant 410a and the second propellant 410b generate propulsive force in the direction shown in the drawing, and the third propellant 410c does not generate propulsive force, The sediment suction apparatus 100 according to the example moves to the top of the figure by the sum of the vectors.

In this case, when the propulsive forces of the first propellant 410 to the third propellant 410 are different, since the suction body 200 moves in the direction of the sum of the vectors of the propulsive forces generated by the three propellants 410, It is possible to move in any horizontal direction by adjusting the driving portions of the first propellant 410a to the third propellant 410c.

Referring to FIG. 10, when each propellant 410 generates propulsive force in one direction, the suction body portion 200 rotates in place.

In other words, the sediment suction apparatus 100 according to an embodiment of the present invention can freely move in any vertical and horizontal directions, so that the underwater sediment at any point can be easily removed.

However, the above-mentioned water tank means a state in which a certain amount of liquid such as water collects, and does not mean only a state filled in a specific container. That is, the sediment suction apparatus according to an embodiment of the present invention has a right range not only in the case of removing the sediment that is filled in the fixed vessel but also in the open space such as river and sea where the sediment is deposited in the water .

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be understood by those skilled in the art that the present invention can be easily understood by those skilled in the art.
