Back-heat accumulator of gliding type underwater launch vehicle

Abstract

A regeneration accumulator of glide underwater vehicle is provided, which belongs to the technical filed of ocean engineering. The invention comprises a cylinder body, a perfusion tube, a floating piston, a cylinder lid, a regeneration layer, an O-shaped cushion rubber, energy transmission liquid, working gas, a piston ring and a plug. The invention utilizes that the working substance of temperature induction generates solid liquid phase change, the working gas storages energy when being compressed and the temperature of the working gas increases and produces temperature difference, the working gas experiencing constant volume exothermic process, the regeneration layer adsorbs the heat discharged from the working gas; then, the working substance of temperature induction starts the a new round of solid liquid phase change, the working gas adsorbs the heat stored by the regeneration layer, during the constant volume exothermic process, the pressure of the working gas returns to the original inflation pressure and thus realizing the whole cycling work. The invention utilizes the energy storage technology of regeneration layer, which makes the accumulator enter the seasonal constant working situation of heat cycle to realize the normal working of the glide underwater vehicle, thus having significant utility value.

Description

technical field [0001] The invention relates to an energy accumulator, in particular to a regenerative energy accumulator of a gliding underwater vehicle, and belongs to the technical field of marine engineering. Background technique [0002] The gliding underwater vehicle, which uses the ocean temperature difference as the driving energy, operates in the thermocline of the ocean. The phase-change working medium in its power system absorbs ocean heat energy, undergoes a phase change, and then causes a volume change, causing the buoyancy of the vehicle to increase and decrease periodically, so that the vehicle can glide up and down the thermocline. In the process of changing buoyancy, the energy is transferred to the energy transfer liquid depending on the volume change of the phase change working medium, and the energy transfer liquid stores the energy in the working gas of the accumulator for timely release when the buoyancy needs to be adjusted. In order to realize the co...

AI Technical Summary

Problems solved by technology

However, since the working gas in the accumulator cannot return to the initial state of the cycle, the power system of the glider cannot continue to work smoothly

[0005] At present, all the accumulators disclosed in the literature do not properly guarantee the cyclic working characteristics when applied in the ocean thermocline
