Autonomous underwater vehicle capable of separating payloads

Abstract

The invention relates to an autonomous underwater vehicle capable of separating payloads. The autonomous underwater vehicle capable of separating the payloads comprises an underwater vehicle body, anunderwater vehicle payload bay and a separating device. The payload bay comprises a shell, a separating device and a payload; and the separating device consists of a pneumatic system and a spring separator. According to the autonomous underwater vehicle capable of separating the payloads, by using a vacuum mode, the end part of the payload bay is connected with the bow of the underwater vehicle body by means of the difference between internal and external pressures at the connected part of the payload bay body; and therefore, the structure with the connecting mode is simple and reliable. Whenthe autonomous underwater vehicle moves to a payload laying area, the pneumatic system of the separating device is started, the vacuum environment at the connected part of the payload bay body is released, and the difference between the internal and external pressures is reduced; and after the difference between the internal and external pressures reaches a separating threshold, the spring separator ejects out of the payload bay. The separating device can rapidly separate the payload bay, the attitude of the separating device is stable, and the separating device is uneasy to collide with the underwater vehicle body; and therefore, payload laying safety and stability of the autonomous underwater vehicle are enhanced, and higher practical significance is realized.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to an autonomous underwater vehicle capable of separating loads and completing load deployment. Background technique [0002] The ocean contains abundant resources, which play a vital role in the development of human beings. As an important means of exploring the ocean, the main role of autonomous underwater vehicles is as a diving equipment and carrier for humans to conduct comprehensive inspections and research on the ocean. Research and complete a variety of assignments. In the military field, autonomous underwater vehicles can carry different types of functional loads, such as mines, detectors, underwater prefabricated weapons, etc., and carry out concealed deployment in predetermined areas to complete monitoring or strike tasks. At present, the main deployment methods of underwater vehicle loads are as follows. For example, the method of explosive bolt ...

AI Technical Summary

Problems solved by technology

At present, the main deployment methods of underwater vehicle loads are as follows. For example, the method of explosive bolt + rotating shaft is used. This method requires that one end of the load is disconnected and separated after turning to a specific angle range. This method is difficult to control, and After separation, the load has a certain rotational angular velocity, which is easy to collide with the carrier and cannot sink in a relatively stable attitude; However, blunt bosses are formed on the front and rear end surfaces of the separated load compartment, which will increase the navigation resistance, reduce the endurance of the aircraft, and cannot achieve long-range deployment.
