Underwater glider

Abstract

The invention discloses an underwater glider. The underwater glider includes a sealing shell, a temperature difference energy buoyancy regulating device and a separate type posture adjustment device,wherein the temperature difference energy buoyancy regulating device and the separate type posture adjustment device are arranged in the shell, the sealing shell is divided into a main cabin, a horizontal wing and a vertical tail. The main cabin is composed of a front compartment, a middle compartment, a rear compartment and a tail compartment, and all the compartments are separated through support plates; an energy accumulator and an inside leather bag of the temperature difference energy buoyancy regulating device are arranged in the middle cabin, and an outer leather bag is arranged at therear end of the tail compartment; when the glider is in work, the buoyancy is changed through the temperature difference energy buoyancy regulating device, up-going and down-going are achieved, the pitch angle of a glider body is adjusted through a pitch adjusting device, placed in the rear compartment, of the separate type posture adjustment device, the rolling posture of the glider body is adjusted through a rocking posture adjusting device placed in the tail compartment, and advancing and turning of the underwater glider are achieved. By more rationally installing the devices of the underwater glider, work is more stable, and a survey can be better completed according to the navigation trajectory.

Description

technical field [0001] The invention belongs to the fields of marine environment monitoring and seabed resource exploration, and in particular relates to a more stable underwater glider. Background technique [0002] With the increasing frequency of ocean activities, humans have gradually expanded from offshore waters to deep sea waters. In this case, the underwater glider was born out of the process of exploring the ocean. Now it is mainly used to detect the parameters of the marine environment, and it also has a high impact on military application value. It is suitable for large-scale, long-distance, and vertical areas of the ocean, and has become a general platform for marine environmental monitoring and applied to actual marine environmental surveys. However, when the underwater glider is working in the ocean, the fuselage is easily affected by the resistance of seawater and the vortex of ocean currents.

Problems solved by technology

However, when the underwater glider is working in the ocean, the fuselage is easily affected by the resistance of seawater and the vortex of ocean currents. This problem increases the difficulty and instability of underwater glider snorkeling, and greatly affects the accuracy of ocean survey data. sex

At present, people have been working hard to design an underwater glider that improves the stability of the fuselage. For example, a shuttle-type underwater glider disclosed in the application document with the patent publication number 201410100504. The resistance of the fuselage improves the stability of the fuselage to a certain extent, but the posture adjustment module in the fuselage front shell of the invention occupies a large space in the cabin, and the battery compartment at the front of the fuselage is also loaded with spare batteries, which causes the fuselage The weight of the front end is relatively large, while the rudder module at the rear of the fuselage takes up less space and is lighter in weight. Due to the random space distribution of each cabin and the unbalanced weight of each cabin in this invention, it is easy to be damaged when working underwater. Due to the influence of ocean currents, the survey cannot be carried out accurately according to the navigation trajectory, and the stability of the underwater glider cannot be guaranteed.
