Variable-gravity buoyancy adjusting cabin

Abstract

The invention discloses a variable-gravity buoyancy adjusting cabin, and particularly relates to the technical field of underwater submerging, the variable-gravity buoyancy adjusting cabin comprises a first cabin shell, a second cabin shell matched with the first cabin shell is arranged on one side of the first cabin shell, a buoyancy adjusting mechanism is arranged between the first cabin shell and the second cabin shell, and a connecting assembly is arranged on the outer side of the buoyancy adjusting mechanism; and a quick pressure discharging assembly is arranged in the buoyancy adjusting mechanism. Through corresponding cooperative use of all the structures, the water pressure in the flexible water bag can be detected in real time, accurate control over buoyancy is achieved, meanwhile, a load rejection block is rapidly close to a flow guide pipe along the screw pitch of a lead screw in the mode that the load rejection block is subjected to load rejection, accumulated water in the flexible water bag is rapidly pushed to the flow guide pipe, and the water storage effect is achieved. The buoyancy adjusting cabin can rapidly reduce the weight of the buoyancy adjusting cabin in an extremely short time in a mode that water can be rapidly discharged, so that the buoyancy of the buoyancy adjusting cabin is rapidly increased, potential safety hazards are avoided, and the buoyancy adjusting cabin has good practicability.

Description

technical field [0001] The invention relates to the technical field of underwater diving, and more specifically, the invention relates to a variable-gravity buoyancy adjustment cabin. Background technique [0002] Underwater submersibles are a new type of ocean detection platform, which can carry a variety of detection equipment, and carry their own energy, and carry out detection in the ocean according to the established tasks. Therefore, it is more and more widely used in the ocean field. The buoyancy adjustment system is an underwater An important part of submersible ascent, dive and attitude adjustment. The adjustable ballast buoyancy adjustment system, that is, the buoyancy adjustment system that changes the system weight, is widely used in deep-submersible underwater self-propelled vehicles; [0003] However, this buoyancy adjustment system is generally equipped with a ballast water tank. When working, the sea water pump is used to fill or drain the ballast water tank,...

Problems solved by technology

[0003] However, this buoyancy adjustment system is generally equipped with a ballast water tank. When working, the sea water pump is used to fill or drain the ballast water tank, so that the weight of the submersible can be changed to adjust the buoyancy. The ballast water tank is in operation. It is necessary to meet both external pressure requirements and certain internal pressure requirements. The external pressure is mainly the diving depth pressure of the submersible, and the internal pressure is when the seawater pump fills the ballast water tank with water. When the maximum adjustment is reached, the cabin is compressed The internal pressure generated by the air is difficult to change adaptively with the amount of water, which makes it difficult for the buoyancy control module to achieve accurate buoyancy adjustment control. At the same time, in case of an emergency, the water inside the buoyancy control module cannot be discharged quickly, resulting in the buoyancy. increase, there is a greater security risk
