Problems solved by technology

Using this way of leaving the cabin increases the complexity of the underwater vehicle system, reduces reliability, and increases the manufacturing cost of the underwater vehicle, and the above-mentioned way of leaving the cabin cannot maintain the dynamics of the weight and buoyancy of the underwater vehicle. Balance, so that the underwater vehicle cannot always maintain a flat state, which can easily cause collision accidents between the underwater vehicle and the bottom or obstacles

Embodiment Construction

[0013] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, the present invention includes the access cabin 3 and the dry cabin 1 that are adjacently arranged in the underwater vehicle, usually the access cabin 3 and the dry cabin 1 are adjacently arranged near the center of gravity of the underwater vehicle, the access cabin 3 and the dry cabin 1 are adjacent to each other. A watertight hatch 6 is provided between the dry cabin 1, and the watertight hatch 6 can be used for frogmen to enter and exit between the access cabin 3 and the dry cabin 1; Enter the outboard from the access cabin 3 for frogmen or enter the access cabin 3 from the outside. In the access cabin 3, a replacement water cabin 4 is provided, and the volume of the replacement water cabin 4 is slightly larger than the volume of the remaining space of the access cabin 3 except the fro...

Abstract

The invention relates to an extravehicular conversion cabin device of the underwater vehicle staff, which is characterized by comprising an access cabin and a dry-type cabin which are adjacently arranged in an underwater vehicle, a watertight cabin door is arranged between the access cabin and the dry-type cabin, the access cabin is provided with a water replacing cabin, the capacity of which is slightly more than that of the remaining space of the access cabin except frogmen; the dry-type cabin is provided with at least one surge tank, the capacity of which is slightly more than drainage volume of frogmen; the water replacing cabin is connected with the access cabin through a pipeline and a pump, and the surge tank is connected with the access cabin through a pipeline and a pump. The extravehicular conversion cabin device of the underwater vehicle staff of the invention has simple structure, good reliability and low manufacturing cost; utilizes water to be replaced to convert back and forth among the access cabin, the water replacing cabin and the surge tank, ensures that buoyancy weight and dynamic equilibrium of floating state of the underwater vehicle in the process of gettingin and out the cabin of the frogmen, and leads the underwater vehicle to be kept in a stable floating state, thus reducing the probability of collision accident occurring between the underwater vehicle and water bottom or between the underwater vehicle and obstacles.

Description

technical field [0001] The invention relates to an underwater vehicle, in particular to an underwater vehicle personnel exit cabin switching device. Background technique [0002] At present, when the underwater personnel of underwater vehicles such as shallow-depth manned submersibles and underwater sightseeing boats go out of the cabin, a transition cabin is usually set up in the middle of the underwater vehicle near the center of gravity. The dry compartment enters the transition compartment, closes the watertight door of the dry compartment to enter the transition compartment, and allows the outboard water to enter the transition compartment. After the transition compartment and the outboard pressure are balanced, open the watertight door of the transition compartment leading to the outboard, and the personnel leave the compartment; Then discharge the water in the transition chamber, and the second person repeats the above-mentioned process of leaving the chamber. During...
