Load rejection module of autonomous underwater vehicle

Abstract

The invention discloses a load rejection module of an autonomous underwater vehicle. A rotating shaft penetrates through an end cover, one end, located on the outer side of an AUV shell, of the rotating shaft is provided with a check block, and the other side of the rotating shaft is connected with a driving unit through a rotating shaft connecting piece. When the driving unit rotates by a certain angle, the rotating shaft is driven to rotate by the same angle. A load rejection heavy block comprises a first load rejection part and a second load rejection part, a circular pit is formed in the middle of the first load rejection part and used for accommodating the check block on the rotating shaft to rotate in the pit, the second load rejection part is fixed on the first load rejection part, a groove with the size larger than that of the check block on the rotating shaft is formed in the second load rejection part, and the shape of the groove is matched with that of the check block. When the check block rotates to the position parallel to the groove of the second load rejection part, the load rejection heavy block falls off, and when the check block rotates by 90 degrees again, the load rejection heavy block can be installed on the AUV. The invention provides a simple and reliable mechanical load rejection mechanism, and the shape of the heavy block can be matched with that of an AUV body, so that the sailing resistance of the AUV body is reduced.

Description

Technical field [0001] The present invention relates to the field of underwater aircraft, and more particularly to a bahunch module of autonomous waterfoot. Background technique [0002] In recent years, the exploration research activities of ocean and lakes have increased more increasingly, and many advantages of autonomous underwater steam (AUV) have become more and more favored by researchers. Due to the complexity of underwater environment, AUV will inevitably have special conditions when performing autonomous tasks. At this time, it is best to quickly float the water surface and recycle to advance for further examination. Therefore, there will be a bahunch module on the general underwater robot. When the central control system determines the failure, the AUV will automatically throw the weight, so that AUV buoyancy is greater than gravity, which can face the water relatively quickly to ensure the safety of equipment. . [0003] A solution of the current AUV is a solution tha...

AI Technical Summary

Problems solved by technology

This scheme has relatively many structural parts and a complex system. At the same time, the shape of the weight is relatively simple, which cannot fit well with the AUV body, and will generate additional resistance during navigation.
