Abstract

A load distribution apparatus of magnetic wheel, includes: a plurality of cylinder parts including one sides respectively connected to a plurality of magnetic wheels and an upper space portion and a lower space portion whose interiors do not communicate to each other; and a passage part which serves as a moving path of fluid and interconnects the plurality of cylinder parts. The passage part is configured to evenly distribute a load applied to the magnetic wheels by moving fluids in the upper space portion and the lower space portion in such a manner that the fluids are not mixed.

Claims

1. A load distribution apparatus of magnetic wheel, comprising:

a plurality of cylinder parts including one sides respectively connected to a plurality of magnetic wheels and an upper space portion and a lower space portion whose interiors do not communicate to each other; and

a passage part which serves as a moving path of fluid and interconnects the plurality of cylinder parts,

wherein the passage part is configured to evenly distribute a load applied to the magnetic wheels by moving fluids in the upper space portion and the lower space portion in such a manner that the fluids are hot mixed.

2. The load distribution apparatus according to claim 1, wherein each of the plurality of cylinder parts includes:

a cylinder body partitioned into the upper space portion and the lower space portion by a piston elevatably provided in the cylinder body; and

a piston rod including one side connected to the piston and the other side connected to the magnetic wheel.

3. The load distribution apparatus according to claim 2, wherein a stopper to limit the descent height of the cylinder body is provided in the cylinder body or the piston rod.

4. The load distribution apparatus according to claim 3, wherein the stopper is provided in the cylinder body or the piston rod located in the forefront and in the cylinder body or the piston rod located in the rearmost.

5. The load distribution apparatus according to claim 2, wherein the cylinder bodies have the same inner diameter.

6. The load distribution apparatus according to claim 1, wherein the passage part includes:

a first passage interconnecting the upper space portions of the cylinder parts to communicate to each other; and

a second passage interconnecting the lower space portions of the cylinder parts to communicate to each other.

7. The load distribution apparatus according to claim 1, wherein the load distribution apparatus is used for cleaning of the bottom of a ship.
