Phase-transition buoyancy adjustment device utilizing residual heat of reactor

Abstract

The invention relates to a phase-transition buoyancy adjustment device utilizing residual heat of a reactor. The phase-transition buoyancy adjustment device comprises a rigid cavity, wherein the uppersurface of the rigid cavity is closed; a plurality of openings are formed at the lower surface of the rigid cavity; a heat insulation elastic cavity is arranged inside the rigid cavity and tightly glued to the inner surface of the rigid cavity; and the inner cavity of the heat insulation elastic cavity is filled with a temperature-sensitive working medium. The phase-transition buoyancy adjustmentdevice also comprises a heat exchange pipeline, wherein the heat exchange pipeline is arranged in the temperature-sensitive working medium except nozzles; and the nozzles on two ends of the heat exchange pipeline both penetrate through the heat insulation elastic cavity and are distributed on two sides of the rigid cavity. The phase-transition buoyancy adjustment device utilizing the residual heat of the reactor can avoid the problem of pump noise of high-pressure seawater and improve the concealment of a submersible; at the same time, the phase-transition buoyancy adjustment device can solvethe problem of energy supply of a traditional phase-transition buoyancy adjustment device, so that the applicability of the phase-transition buoyancy adjustment device is improved; and the buoyancy adjustment amount is adjusted according to the temperature-sensitive working medium stored inside the phase-transition buoyancy adjustment device so as to improve the accuracy of the buoyancy adjustment and facilitate the maintenance in the later period.

Description

technical field [0001] The invention relates to the field of buoyancy adjustment systems, in particular to a phase-change buoyancy adjustment device utilizing reactor waste heat. Background technique [0002] The buoyancy adjustment system is one of the subsystems of the underwater submersible. When the submersible is navigating and working underwater, many factors will affect the buoyancy or gravity of the submersible, such as the change of seawater density in different waters, and the deformation of the submersible under high pressure. , the increase or decrease of gravity caused by dumping or sampling. In order to compensate for changes in the buoyancy of the submersible or to adjust the underwater depth or attitude of the submersible, the buoyancy adjustment system is very important. [0003] Commonly used buoyancy adjustment systems are mainly divided into adjustable ballast type and variable volume type. The former adjusts the buoyancy by adjusting its own ballast qua...
