Description

DESCRIPTION

Unmanned underwater rescue and surveillance system.

Object of the invention 5

It is the object of the present invention to offer an unmanned underwater vehicle and piloted by remote control for rescue and surveillance tasks.

Background of the invention 10

At present, rescue systems at sea are ships or manned aircraft that respond to signals sent by the crews or by automatic assistance systems and currently the use of remotely piloted aircraft is started.

 fifteen

The rescue systems mentioned in the previous paragraph have to deal with atmospheric and marine conditions and as accidents or shipwrecks at sea usually occur during storms, relief teams or have serious difficulties in going to the place of the event, risking their lives, or even cannot come to help.

 twenty

On the other hand, it is known that the storm does not affect the conditions of the sea from a certain depth where navigation is calm, this is used by manned submarines since the beginning of underwater operations.

The present invention offers a rescue system that navigates in depth, so that it is not affected by the state of the sea, and that is piloted remotely so that the "crew" do not risk their lives in the operations of rescue.

Description of the invention

 30

The unmanned underwater rescue and surveillance system object of the present invention comprises:

to. A remote control and pilot system and

b. An unmanned underwater vehicle of those that include a propellant system and a heading and depth government system, which in turn comprises: 35

 A closed compartment with doors that can be operated at will that houses inside an inflatable raft by means of an automatic inflation device,

 One or more lithium-ion rechargeable electric batteries that power the propulsion system, the government system and the rest of electronic devices,

 One or more compressed air tanks,

 A watertight compartment in which the following systems are arranged inside:

o One or more global satellite navigation systems, 10

o One or more radio frequency communication systems,

o Surveillance systems through at least a television camera, infrared camera, radar, sonar and

o One or more control computers of the systems and devices for processing the signals of the communications and surveillance systems.

 One or more lighting and signaling devices.

Preferred Embodiment of the Invention

Figure 1 shows a preferred embodiment of the unmanned underwater vehicle (1) that is controlled and governed by a remote control and pilot system, located either on the ground, either in an aircraft or in a ship. 5

The underwater vehicle comprises a closed compartment (2) where an inflatable raft is stored that has an automatic inflation device that acts when the raft is released, between the raft and the underwater vehicle there are towing means that allow the invention to tow the rafts to a safe place or where they can get help. Of course, the raft is provided with food, drinking water, first aid equipment and communications.

To increase the safety and maneuverability of the underwater vehicle, it has two thrusters (5) powered by one or more rechargeable electric batteries (3), preferably lithium-ion batteries, and in the event that greater autonomy is required for some Auxiliary electric batteries (7), also preferably lithium-ion, which are located at the ends of the stabilizers (6), which are one of the components of the steering system.

 twenty

To facilitate rescue and surveillance work, one or more signaling and lighting devices (8) are conveniently available that allow the vehicle to be located more easily and that illuminate the areas required for the fulfillment of the mission entrusted.

 25

Depending on the depth to which the underwater vehicle is required, it can be made of steel or fiberglass.

In addition to salvage work, the invention can carry out surveillance and control operations of marine traffic, fight against smuggling or location and monitoring of 30 marine animals such as cetaceans.

Claims (7)
