[0025] Submersible pump 4 pumps water from the bottom of the water supply pipe 1, which then sprays it out of outlet pipe 2 at high speed, ensuring a constant flow of water around the tower's water inlet and preventing ice from forming on the surface. Furthermore, a lifting device 5 and lifting rails 6 allow the position of water supply pipe 1 to be adjusted to suit varying water levels, enhancing the device's versatility.

[0026] Example 2:

When the submersible pump 4 approaches the plane of the water supply pipe 1, the pressure difference between the water inlet of the submersible pump 4 and the water outlet of the outlet pipe 2 decreases, and the flow rate of the water ejected from the outlet pipe 2 increases. When the submersible pump 4 moves away from the plane of the water supply pipe 1, the pressure difference between the water inlet of the submersible pump 4 and the water outlet of the outlet pipe 2 increases, and the flow rate of the water ejected from the outlet pipe 2 decreases.
