Abstract

The invention discloses a submarine surfacing device. The submarine surfacing device comprises at least one submarine surfacing unit arranged in a water ballast space of a submarine; each submarine surfacing unit comprises a compressible water sac and an osmotic membrane. The compressible water sac is connected with a fresh water source arranged in the submarine and used for receiving fresh water from the fresh water source at least when submarine is to surface; one side of the osmotic membrane is connected with the compressible water sac, while the other side of the osmotic membrane is connected to the outside of the submarine, and the osmotic membrane is used for draining the fresh water in the compressible water sac out of the submarine. The submarine surfacing device is capable of draining the fresh water in the compressible water sac when the submarine has a fault and thus reducing the weight of the submarine to achieve the purpose of surfacing.

Description

technical field [0001] The invention belongs to the technical field of submarines, in particular to a submarine floating device. Background technique [0002] When submarines perform various combat missions and conduct training, they need to perform various complex maneuvers. Due to the complex and changeable submarine hydrological environment, densoclines and ocean internal waves can be seen everywhere, and some unpredictable failures of submarine system equipment, All of these will have a great impact on the normal navigation of the submarine that has been dynamically balanced. [0003] Submarine malfunctions under water will directly endanger the safety of the crew on board, and emergency flotation measures are often adopted for malfunctioning submarines. Submarine emergency flotation usually refers to the process of removing part or all of the seawater in the main ballast water tank when the submarine navigating underwater is in a dangerous state due to an accident and ...
