Floating device of deep water unmanned submarine

Abstract

The invention discloses a floating device of a deep water unmanned submarine. The floating device of the deep water unmanned submarine comprises a deep water submarine. The deep water submarine is provided with an inflatable chamber for holding a gas source, a fairing, and a floating bag positioned in the fairing. The floating bag is provided with a safety valve, a differential pressure valve, and an inflatable nozzle communicated to the interior of the inflatable chamber, the floating bag is internally provided with an inflatable manifold connected with the inflatable nozzle, the inflatable manifold is connected with a plurality of flexible air ducts, a plurality of exhaust vents are sequentially provided on the flexible air ducts along the pipeline, and the inflatable nozzle, the inflatable manifold, the flexible air ducts and the floating bag form a loop. According to the invention, the inflatable manifold is provided, so that gas becomes multi-point output from single-point input, the instantaneous inflation pressure around the inflatable nozzle is decreased, and the synchronization of inflation is improved; the flexible air ducts are additionally provided, so that gas flows to the folding end of the inside of the bag in the first time, the synchronization and uniformity of rapid inflation are improved, and the risk of bursting of the bag caused by too high local pressure due to uneven inflation is avoided.

Description

technical field [0001] The invention belongs to the field of marine technical equipment, and in particular relates to a floating device for a deep-water unmanned submersible. Background technique [0002] Deepwater unmanned submersibles need to be recovered at different depths, and the recovery method of floating bladder inflation is a commonly used recovery method. When the unmanned submersible is navigating in the deep water area (100m ~ 200m), the floating bag is restrained in the fairing of the submersible by folding, and the deep water pressure acts on the outer surface of the unmanned submersible. Entering between the fairing and the floating bag, the floating bag is in a strong folded state due to the action of water pressure. When the floating inflation mechanism quickly inflates the floating bag, the floating bag cannot be inflated synchronously due to the folding constraints, and the inflation speed is too high. Fast and the folded floating bag opens slowly under ...

Problems solved by technology

When the unmanned submersible is navigating in the deep water area (100m ~ 200m), the floating bag is restrained in the fairing of the submersible by folding, and the deep water pressure acts on the outer surface of the unmanned submersible. Entering between the fairing and the floating bag, the floating bag is in a strong folded state due to the action of water pressure. When the floating inflation mechanism quickly inflates the floating bag, the floating bag cannot be inflated synchronously due to the folding constraints, and the inflation speed is too high. Fast and the folded floating bag opens slowly under the limitation of water pressure, which may cause the local pressure near the inflation port of the floating bag to be too high and the floating bag has not yet opened; thus making the pressure near the inflation mouth exceed the pressure limit that the floating bag can withstand , leading to the rupture of the floating bag and the failure of inflation

[0003] At the same time, due to the high water pressure in the deep water area, the volume of the inflated gas that the flotation device of the unmanned submersible vehicle needs to carry increases relatively, so that the folding space of the floating bag is further compressed. zone inoperable state
