A full-sea unmanned submersible

Abstract

The invention discloses a full-sea-depth unmanned submersible. The full-sea-depth unmanned submersible is characterized in that low-cost easily-available lightweight common materials resistant to seawater corrosion and collision and having a certain structural strength are used for making a dimensional shell of the submersible; the interior of the submersible and all interior gaps of all equipment, facilities and components carried by the submersible are filled with liquid, so that a closed space type pressure resisting mode that an exterior hard pressure-resistant dimensional shell of a previous submersible bears all pressure is converted into a material-type pressure resisting mode that materials for manufacturing the dimensional shell of the submersible as well as the equipment, the facilities and the components carried inside the submersible bear pressure jointly. The full-sea-depth unmanned submersible has the advantages that the characteristics that liquid is incompressible, liquid with a roughly consistent density bears no larger pressure and the pressure is conductible are used, so that manufacturing cost of the submersible is reduced significantly, and the submersible is not restricted by a submerged depth.

Description

technical field

[0001] The invention belongs to the technical field of submersibles, and in particular relates to an unmanned submersible for full sea depth. Background technique

[0002] In recent years, with the rapid development of a series of marine development undertakings such as deep-sea prospecting, oil exploration, and sample collection, cable and pipeline laying, cross-sea bridge construction, and a series of marine development undertakings such as scientific research and surveying, photography and observation, the construction of deep submersibles and demand has increased dramatically.

[0003] However, in the deep sea environment, the natural environment is very harsh and dangerous, and there are a series of problems such as seawater corrosion, resistance, power supply, communication means, observation and position maintenance. In particular, the water pressure-resistant lightweight container, material, and cost of deep submersibles are much more difficult than ...
