"ROTATING FLOATING PLATFORM"

Technical Field

The present application describes a rotating floating platform.

Background art

Current energy production centrals based on photovoltaic cells, ranging different scales, are installed either on ground (onshore) or on pre-existing structures. These systems are rarely installed in water surfaces such as lakes, lagoons, ponds, dam reservoirs, rivers, among others.

The document WO 2012/131543 describes a solar panel floating structure which is made up of a floating platform rotating about its vertical axis by means of a rail system, anchored to the bottom of the hydrographic basin and its margin. The rotation movement of the structure is limited to pre-defined positions and held in place by fixation means of the rotating platform in reference to the fixed structure.

The document FR 2988164 describes a system where a rigid structure designed to accommodate solar panels revolves around a central axis by means of floating components traveling within a well-defined path.

The document US 4786795 describes a platform that is designed only to track the solar movement, by using a plurality of solar tracking subsystems which provide information for the control system to activate the motors which can work forwards or backwards, rotating the platform about a fixed structure.

The platform can also be floating without being fixed to a central structure by means of a cable and pulley system that is fixed to the bottom of the basin and is connected to the platform on its extremities .

General description

The technology now developed describes a rotating floating platform, providing rotational movement to the entire structure, on the plane of the aquatic medium where it floats .

The system herein described is designed, but no limited to, floating platforms adapted to accommodate energy production systems, namely solar panels but not limited to these systems .

The main innovation in the present application is the ability to deploy the rotating floating platform in any aquatic medium, being its rotation capacity independent of fixed and rigid structures. In order to achieve this independency, the rotating floating platform comprises a central floating module connected directly or indirectly to a plurality of propulsion modules, where the connection to the bottom of the basin being provided through a flexible mooring unit, forming a rotation floating structure where the momentum and the rotation axis act as one, thus creating a rotation platform.

The central floating module comprises a central floating component and an outer component that can rotate independently from the central floating component by means of a bearing type connection, thus granting rotational freedom of said outer component.

The platform is assembled by attaching any other floating components to the outer component by using a fixation mechanism like a rope, therefore granting the platform a freedom to rotate around the central floating component. The central floating component is a buoy with means for fixating both the outer component and the mooring unit.

The rotating floating platform is free from fixed structures, and comprises a mooring unit of an anchor type, fixed to the central module by means of a swivel and rope connection, thus connecting it to the bottom of the basin. In the context of this application, anchor type connection should be understood as a flexible connection type made of a flexible connection element such as a rope, having in one of its extremities an anchor mechanism to provide the mooring of the entire platform. This approach has the advantage of not limiting the planar movement of the platform along the water plane .

The propulsion module comprises a motor unit, which is coupled to at least one floating component. Said motor unit comprises an engine operated by a control unit having processor means configured to operate the respective motor, and therefore defining the rotational movement direction of the propeller attached to it, according to instructions received by external entities responsible for controlling the rotational movement of the platform. For that purpose, the control unit also comprises a communication module configured to establish wired/wireless communication links to said external entities. The connection between the control unit and the motor is provided by a vertical stick, which holds the motor in a pre-defined distance between the bottom surface of the platform and the ground.

The motor unit comprises additionally a fixation mechanism to attach the referred unit to the floating component. The fixation mechanism comprises a rigidly mechanical tubular frame that is attached to the floating structure, namely, to two floating components, by means of a connection mechanism. Said connection mechanism could be of a clamp and screw type. The motor is coupled to the fixation mechanism by a plate, serving as a spacer, using a screw type connection.

By combining both these sub systems, we can create a floating platform that revolves freely around an axis, created by the central module, driven by the momentum generated by the propulsion modules, creating a floating platform with rotational ability. For the sake of this solution, the propulsion modules are mounted on the extremities of the floating platform, thus maximizing the moment of the movement .
