Sludge bricks as a product have objective economic benefit.

The invention relates to a novel hovercraft ice breaking device and a method thereof, and belongs to the technical field of ice breaking. As that electromagnetic induction principle is utilize, a high-energy electromagnetic inductor is adopted in the induction heating ice breaking system, At the same time, the main engine of the ice breaker drives the icebreaker to rotate, and the ice breaker breaks the ice surface rapidly through mechanical collision and thermal effect in the process of contacting with the ice. After combining with the technology of the air cushion vehicle, there are three ice breaker modes to cause the ice layer damage. The invention realizes the non-contact rapid heating of the ice breaking teeth, improves the low-temperature ice breaking adaptability and the ice breaking efficiency of the ice breaking system, and enhances the ice breaking ability of the ice breaking system. Flexible ice breaking at any position on the ice surface; the required equipment is simple in structure, smaller in overall size, and much thicker and more suitable for ice breaking than other icebreakers. It can be used as the main ice breaking method in inland rivers and lakes and coastalwaters, as well as the auxiliary ice breaking method for ships in polar ice areas.
