An unmanned ice-breaking submersible

Abstract

The invention provides an unmanned under-ice ice-breaking submersible. The tail part of a hull is a hull ballast tail provided with ballast; an ice-breaking drill is arranged at the front end of a bowof the hull; a watertight transverse bulkhead is arranged at the middle in the middle part of the hull; the watertight transverse bulkhead divides the space in the middle part of the hull into a first ballast tank and a second ballast tank; the top ends of the first ballast tank and the second ballast tank are respectively provided with high-pressure air cylinders and high-pressure air pipes; oneend of each high-pressure air pipe communicates with the corresponding high-pressure air cylinder and the other end of each high-pressure air pipe is a closed end; the first ballast tank and the second ballast tank are both provided with seacocks and air vent valves at the bottom ends; each high-pressure air pipe is also provided with a corresponding high-pressure air valve switch; the two high-pressure air cylinders communicate with each other; and the high-pressure air cylinder in the second ballast tank also communicates with an external umbilical cable. The unmanned under-ice ice-breakingsubmersible is simple in structure. When a polar ship encounters an ice area requiring higher ice-breaking capacity than the ice-breaking capacity of the ship, the polar ship can break the ice and navigate by virtue of the unmanned under-ice ice-breaking submersible, so that the ice-breaking capability of the ship under extreme conditions at the ice area can be greatly improved.

Description

technical field [0001] The invention relates to an unmanned submerged ice-breaking submersible, which belongs to the technical field of ice-breaking. Background technique [0002] At present, icebreakers or other icebreaking equipment mainly achieve icebreaking by applying load to the ice surface on the ice to overload the ice surface. The icebreaker tilts the bow to squeeze or collide with the ice surface to generate load. , vibration and other ways to generate loads on the ice surface, traditional icebreaking equipment often has problems with large structural design or complicated control. Have not yet seen that there is an ice-breaking equipment that only utilizes its own buoyancy and ice-breaking structure to break ice by changing its own drainage state. Contents of the invention [0003] The purpose of the present invention is to provide an unmanned submerged ice-breaking submersible specially for breaking ice from below the ice surface in order to be different from ...
