[0023] Working principle: When the water tank 1 is moved by the universal wheel 2, the water inside the water tank 1 moves under the action of inertia. During the movement of the water, it hits the partition 8 inside the water tank 1. The multiple partitions 8 can evenly distribute the impact force of the water flow, and when the water flow passes through the buffer hole 9 of the partition 8, the impact force of the water flow can be reduced, so that the movement and placement of the water tank 1 can be more stable;
