Description

Ultra-deep load rejection device and underwater vehicle Technical Field The invention relates to the field of underwater vehicles, in particular to an ultra-deep load rejection device. Background Unmanned Underwater Vehicles (UUVs) are widely used in the field of underwater exploration by means of their automatic route planning and autonomous navigation. When encountering a large ocean current influence or sudden change of the sea water density, the underwater vehicle may generate ultra-deep navigation due to the limitation of the control performance of the underwater vehicle, particularly for the low-speed navigation, once the ultra-deep phenomenon occurs, the floating is difficult to realize based on steering, and the structural strength of the vehicle is destructively influenced. For large-sized aircrafts, a water storage cabin is arranged in the large-sized aircrafts, the large-sized aircrafts can float upwards through water drainage under the ultra-deep condition, and the small-sized aircrafts float upwards in a throwing and loading mode. The common mode is to detect the depth through a pressure sensor, the control device gives out a signal to release the throwing load, or the electromagnetic adsorption type or the explosion bolt type is adopted, the electromagnetic adsorption type needs the aircraft to provide a control program and energy for a long time, and the explosion bolt has a certain initiating explosive risk and is unfavorable for noise reduction and safety. Aiming at the problems of the electromagnetic adsorption type and explosion bolt type load rejection device, no effective solution exists at present. Disclosure of Invention In order to solve the problems, the invention provides an ultra-deep load rejection device and an underwater vehicle, which complete the release of load through the cooperation of a mechanical structure, do not need long-time energy and program supply, reduce noise and improve the safety so as to improve the reliability and concealment of the load rejection process.
