Method for cleaning ice in canal

专利摘要:
The method and the apparatus for removing ice from a ship's channel or from around the ship, to ease its navigation. The invention is characterized in that the propeller stream is used for removing the ice by turning the propeller stream up to the surface where the ice is. The removing influence of the stream can be further strengthened by diverting it also to the sides. Turning up the stream can be done for instance by mixing air into the propeller stream. Mechanical foils (8), for instance tilted ploughing rudders (9,10), can be used for turning the stream up and to the sides. The same air blowing apparatus can be used also for other applications, as loading the payload, or for biological aeration of water.

The method of removing ice in the channel, which consists in the direction of the water flow from the main propellers to the sides of the diametrical plane of the vessel. that _g in order to increase the efficiency ί purification ice in the channel, the water flow from the propellers deflect upwardly to the surface water area by feeding into it an air flow over the propellers.
