TECHNICAL FIELD OF THE INVENTION

The present invention relates to the area of search and rescue equipment at sea, remotely controlled and applicable to all situations of shipwrecked people rescue, able to be used from land, sea and air.

The present invention may also be included in the recreational nautical equipment.

STATE OF THE ART

Various search and rescue equipment at sea are known from the prior art, which however present several limitations in what concerns the format itself, the mobility and the navigational capabilities in adverse conditions.

Document WO 2012139044 A1 discloses a buoy with a motor comprising a hull, a floating device coupled to the hull that is configured to maintain the buoy in an upright position, a motor embedded in the hull and a mechanism activated by remote control device. However, this device, considered the most representative of the state of the art, can only navigate in the position in which it is placed on the water.

The present invention solves the technical problem of being able to navigate in all conditions, regardless of how it is placed or thrown into the water, or when it turns upside down. Basically, the device can navigate on any of its sides by automatically switching the water inlets.

SUMMARY OF THE INVENTION

The present invention relates to a U-shaped self-propelled craft directly and remotely controlled, running through two turbines and respective motors that allow navigation on any of the sides.

The manoeuvrability achieved with the present vehicle features an extraordinary performance, and even in the most demanding sea conditions the behaviour and control of the self-propelled vehicle show to be very effective. This is achieved by the high power propulsion system and turbine operation system of the invention.

Experiments in those sea conditions show that the rescue of shipwrecked people is facilitated, either because the device arrives very quickly to the place of the shipwreck, or because the remote control is reliable and robust.

The vehicle can be used both on beaches, as auxiliary equipment of lifeguards, and on board ships, interacting with a safety device that automatically releases the vehicle when someone falls overboard and allowing it to be guided by the electronic control module to the place where the person to be rescued is, or even on unsupervised or remotely supervised beaches, in this case being in stand-by on a support platform automatically released into the water by an electronic alarm.

Additional advantages of the invention are:

• • quick aid to the shipwrecked person;
  • ease of use, by both the rescuer and the shipwrecked person;
  • navigation capability in adverse sea conditions;
  • reduced dimensions that facilitate the storage on land, sea or air means, and consequent versatility of use;
  • usage as recreational nautical equipment.

Another feature of the device is its “U” shape, which facilitates the navigation and the entry of the shipwrecked person, thus replacing the traditional circular “lifebuoy”. The shape design allows it to navigate on rough seas and waters, reaching rapidly the shipwrecked person and being able to be launched from land, from ships or aircrafts.

Equipped with full mobility, the device can quickly reach the shipwrecked person and will be able to bring him/her to shore or to the nearest support point. To achieve these features it was developed starting from the basic concept intended to be replaced, the static buoy, now provided with propulsion. The final form reached is the one that best meets the requirements: ease of use, both by the lifeguard and by the shipwrecked person; navigation capability in difficult sea conditions; reduced dimensions that facilitate its storage on vessels; versatility of use, whether used from land, with or without a lifeguard, or from a vessel or an aircraft, and also as a recreational vehicle.

One of the great difficulties of a shipwrecked person is to put himself on the circular buoy, a situation that is totally overcome with this device.

This vehicle has an electronic module for navigation and orientation. The electronic module is placed on the front and inside the device. It consists of a magnetometer, an accelerometer and a gyroscopes, a GPS, a system of audio/video and a traction control which is activated in critical situations at sea and which provides a more balanced propulsion of the turbines.

The self-propelled craft may also include a surveillance/tracking optical system, consisting of cameras and software that detects requests for assistance through movements performed by the shipwrecked person warning the lifeguard, or it may be released to water automatically.

The present invention is designed to provide assistance to persons in situations of drowning in seas, rivers and lakes, and for recreational use.

The remote control was integrated into a small, robust and completely waterproof equipment, intended for ease utilization in one hand, by any person. It is provided with a telemetry system that controls the batteries level and that can be monitored in the command itself through visual and audible indication.

The device can be recharged directly on a mains plug or by induction. The slow and/or maintenance charging is done by induction, while rapid charging is done by direct connection. The charging will be made through a solar panel or other alternative energy sources integrated in the holder where the device is.

DETAILED DESCRIPTION OF THE INVENTION

The present invention comprises a self-propelled craft with a U-shaped main body provided with two turbines (7), one on each flap (2) of the U-shaped main body, which propel the self-propelled craft (1) through turbine operation in a chamber (8), fed by water received by water intakes (4) that is ejected by the ejection openings (3), and which turbines (7) move inside the turbine operation chamber (8) adopting automatically one of two possible positions due to the casing (15) which is placed in two different positions within the turbine operation chamber (8), which positioning results from the placement of the device on the water being done by side A or B, the water intake being done through existing water entrances (4) on side A or B of the device.

The casing (15) can be a part with the inner shape of the turbine operation chamber (8) that allows an easy sliding of the turbine (7), or it may be the interior of the turbine operation chamber (8) itself, as long as it has the necessary surface finish for an easy sliding of the turbine (8).

The self-propelled craft also comprises a battery (5), an electronic control module (16) and drives (10).

The drives (10) are of the speed drive type, providing a smooth operation of the turbines (7), avoiding power surges that would increase the batteries consumption and allowing for easier manoeuvrability of the craft.

The self-propelled craft communicates with a communication device at a distance (12), which allows controlling of said vehicle.

Beyond the self-propelled craft and the distance communication device, the system further includes a seating platform and a charging platform for the craft and device.

In a preferred embodiment of the invention, the self-propelled craft has handles (14) on the flaps to facilitate rescue.
