Emergency ventilation device applied to underwater vehicle and submersible

Abstract

The invention discloses an emergency ventilation device applied to an underwater vehicle and a submersible. The device comprises an inflation float ball, the middle of the inflation float ball is provided with a through hole which is used for a ventilation extending pipe to penetrate through, the bottom of the ventilation extending pipe is provided with an air guiding hole which is communicated with one end of a connecting hose, the other end of the connecting hose is communicated with the interior of a cabin of the vehicle, the bottom of the ventilation extending pipe is movably connected with an emergency handle, and the emergency handle is arranged in the cabin. According to the emergency ventilation device, natural buoyant force of the float ball is utilized, emergency come-up is conducted by carrying the ventilation hose under emergency situations, so that the restriction of the diving depth is greatly improved theoretically, an end ventilation pipe can automatically extends out under illumination sensing to allow the ventilation pipe to be reach the part above the sea level with safety distance, so that it is ensured that the ventilation pipe can be normally used under certain wind-wave situations, and the sea water back flooding is avoided. The emergency ventilation device has the advantages that the overall operation is simple, it is only needed to pull the emergency handle hard under emergency situations to achieve the emergency ventilation function, and the safety performance is greatly improved.

Description

Technical field [0001] The present invention relates to the technical field of underwater vehicles, in particular to an emergency venting device applied to underwater vehicles and submersibles, and is suitable for emergency venting of various underwater vehicles and submersibles in the case of loss of cabin ventilation. Use to ensure the safe use of underwater vehicles. Background technique [0002] Ventilation and ventilation is an indispensable and important function of underwater vehicles and submersibles. It directly affects the life and safety of personnel in underwater vehicles and submersibles. Therefore, sufficient ventilation and ventilation means must be provided. At the present stage, fixed rod type venting devices are mostly used, but this type of venting device has higher requirements for diving depth. When the depth exceeds a certain depth, the function fails due to the inability to reach the water surface. At the same time, external force is required to extend the...

Problems solved by technology

At this stage, fixed-rod ventilation devices are mostly used, but this type of ventilation device has high requirements for diving depth. When the depth exceeds a certain depth, the function will fail because it cannot protrude out of the water.

At the same time, an external force is required to make the air-permeable rod protrude, which is inconvenient to operate and low in efficiency, especially in an accident state, and the safety is not high
