Abstract

The invention provides an external navigation power system of a ship and a use mode thereof. The power pod can be positioned in a docking area of the vessel and can be fixedly but detachably connected to the vessel in the docking area, or in use, the power pod is separated from the hull, positioned in the water, at a distance from the vessel, and remains connected thereto by a connecting wire.

Description

External navigation power system of ship and use mode

Technical Field

The invention relates to an external navigation power system of a ship and a use mode, relates to the field of underwater exploration, monitoring and measuring systems and the field of marine defense, and particularly relates to an autonomous underwater external power cabin system for launching and recovering preprogramming or remote operation, which is used for exploration, detection and naval defense in a water environment.

Background

Automatic underwater propulsors are commonly referred to as AUVs. Different systems are known for launching and retrieving automatic underwater propulsors from transport vessels or on land. These systems may be recovery ramps, floats or baskets, or may be simple lifting devices such as cranes or gantries. Such systems are effective for autonomous underwater pod launch, but are less efficient for recovery of underwater vehicles.

One of the difficulties relates to the docking work to recover the propeller. In fact, whether or not ramps or manipulators are used, it is in most cases necessary to stop the propeller beforehand. Without manual operation, it is difficult to install the thruster on the vessel at sea and it is essentially impossible to do so when it is desired to recover the thruster from the vessel, whether it is autonomous or remotely operated.

Disclosure of Invention

In order to remedy the above-mentioned drawbacks of the prior art, the present invention proposes an underwater remote external power pod system which is operated by wire, is therefore wire-guided, and remains underwater during launch and recovery. The power pod is transported by the thruster unit before launch and after recovery. After launching and before recovery, the propeller is separated from the power cabin body and can be automatically navigated.

The underwater power pod is mobile, comprising propulsion and guiding means, and since it is provided with stabilizing means at the same time, it is able to maintain its stable position under water according to all the axes, i.e. three axes, six degrees of freedom, so that it is not affected by waves and by the ship's movements during launch and recovery of the power pod, since the outboard pod is completely in the underwater position.

The underwater power cabin comprises a docking station, and at least one power cabin in or beside the docking station can be automatically accommodated. The shape of the docking station is generally similar to the shape of a cylinder with a flare, i.e., funnel-shaped, and is equipped with a pod-based self-docking station system. Such a submerged vehicle with docking station may be launched from a manned or unmanned vehicle, or in the latter case, from an automated or wired lead or tow vehicle. The invention therefore relates firstly to a system for launching and recovering an automated underwater vehicle using a surface carrier comprising a hull and an automated underwater vehicle (power pod) comprising propulsion means.

Drawings

FIG. 1 shows one embodiment of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, the carrier vessel 2 of the system is a single hull, sea-going vessel and includes a keel 20 for stabilizing it. For conventional mechanically propelled craft, particularly high speed craft, where this is not required, the single hull wave-transparent carrier vessel 2 includes a keel 20 which, due to its inverse mandrel shape to that of conventional mechanically propelled craft, contributes to its stability. Such single hull transport vessels are used in particular for acoustic measurements in water, the keel of which comprises, in addition to the underwater vehicle to be transported, also measuring devices which have to be left in the water. The ship must therefore be able to penetrate the waves thanks to a blade-shaped bow 25, while sailing at high speed and with reduced energy consumption. The vessel 2 has a removable keel which at its underwater lower end comprises an area 21 forming a storage area for the power pod 3. A sensor, in particular an acoustic sensor 27, is mounted in close proximity to this region 21. In fig. 1, a propulsion device 4 is mounted in a power pod 3. Such an arrangement of storing the power pod 3 on board the vessel may correspond to a displacement towards the area of use where the propeller 4 is to be released.

The keel 20 is removable and can be raised and lowered through the keel shaft of the hull. It is noted that the cab 22 is located on the axis of the keel 20.
