The hybrid power underwater glider comprises a front immersion cabin section, a front pressure-resistant cabin section, a middle pressure-resistant cabin section, a rear pressure-resistant cabin section, a rear immersion cabin section, heat exchangers and horizontal wings, wherein the cabin sections are fixedly connected in sequence along a cylindrical rotation axis to form a hybrid power underwater glider body part, the heat exchangers are externally hung on a bellypart of the body, the horizontal wings are horizontally arranged on two sides of the rear pressure-resistant cabin section, the hybrid power underwater glider battery pack has two degrees of freedom of translation and rotation, and can be used for adjusting a pitching attitude angle and a course angle of the underwater glider; a hydraulic device in the main machine body and the heat exchangers form a hydraulic oil path, and in the diving preparation stage of the hybrid power underwater glider, an oil return path works, in the diving gliding stage, a solidification oil path works, in the floating conversion stage, the energy release oil way and the oil pumping oil way work, and in the floating gliding stage, the energy storage oil way works, and the buoyancy driving process is completed bycompounding two forms of energy, namely battery electric energy and ocean temperature difference energy.

Description

technical field [0001] The invention belongs to the technical field of new marine unmanned vehicles, and in particular relates to a composite power underwater glider using two energy sources, the electric energy of a self-carrying battery and the ocean temperature difference energy in a natural environment. Background technique [0002] Underwater glider is a kind of ups and downs in seawater relying on the change of buoyancy state. It uses wings to convert buoyancy into horizontal driving force. The trajectory-moving unmanned underwater vehicle has the advantages of strong self-sustainability, long endurance, and high cost-effectiveness. It is suitable for carrying out large-scale, long-sequence three-dimensional continuous ocean observation activities, and has broad application prospects in the field of ocean observation. [0003] At present, commercial underwater gliders rely on their own battery power to meet the energy required for the gliding buoyancy drive process and...

AI Technical Summary

Problems solved by technology

[0004] However, the temperature difference energy underwater glider scheme still has many deficiencies: 1. The temperature difference energy drives the underwater glider. There is no other buoyancy driving energy except the temperature difference energy of the ocean environment. If the temperature difference energy conversion and utilization system fails, the temperature difference energy underwater glider will lose its continuous navigation. 2. The sea area and seaworthy time range of the thermoelectric energy glider are limited, and limited by the thermophysical properties of the phase change material that captures the ocean thermal energy, a temperature difference of more than 10°C must exist in the ocean to satisfy the thermal energy water. The continuous operation requirements of the glider are affected by the solar radiation intensity of the surface seawater and the latitude of the earth. The sea area that meets the temperature difference condition for the continuous operation of the underwater glider generally only exists between the earth's north and south latitudes of 35°, and some sea areas are only navigable in summer. ; 3. Unconventional temperature profile ocean phenomena such as weak temperature difference and inverse temperature difference randomly exist in the ocean. When encountering such ocean phenomena, the temperature difference can cause the glider to lose power underwater, and there is a risk of not being able to surface and being lost
