Detailed description of the invention
The present invention relates to an omnidirectional wind-capture modular device (1), comprising at least one energy generating module and comprising two main parts, the outer section (4) and the inner section (3) that includes the rotor and the electronic component.
The substantially quadrangular outer section (4) is comprised of a plurality of removable wind capture means (4A), having three predefined widths and which are in synchronization with the capture means (3) of the inner section (2), thus forming flow channels (5) with angles of attack as a function of the wind conditions. The inner section (2) also comprises a plurality of wind capture means (3) that are constituted by two arcuate surfaces (3A) with predetermined angles and by three flat surfaces (3B) . This inner section (2) and all its component parts define a substantially circular area, which is coupled around a rotor 6, which functions within this area.
The rotor 6 is comprised of a steel shaft which has coupled at least three displacement means 6A, two discs of magnetic material 7 with a plurality of neodymiums disposed about the axis of said rotor (6) and a circular printed circuit board located between the two disks (7), where the excitation coils, the power coils and the power management electronic controller 8 are located.
The operating mode of the omnidirectional wind-capture modular device (1) is relatively simple and the main characteristic lies in the way it performs the wind capture. The combination and synchronization between the capture means (3) of the inner section (2) and the removable capture means (4A) of the outer section (4) enable the capture of light breezes, as well as the extraction of the surplus when high wind speeds occur. The flow channels (5) formed by said capture means (3) and (4A) have a tapered shape, progressively narrowing, which allows the increase of wind speed at the inlet, creating the necessary pressure to start rotation and consequent operation of the rotor (6) . The wind capture is carried out laterally at any position and from the moment of entry into the device (1) and, after traversing the flow channels (5), starting the process of operation of the rotor 6, the captured air will leave through the opposite side of the entrance, since the device (1) is provided with an enclosed top and base.
The rotor 6 has permanent assistance and control via the electronic controller 8 that performs the programmed power management and control by its own software (not shown) .
The omnidirectional wind-capture modular device (1) is further provided with a local synoptic table, where anomalies and functions can be checked at the time, as well as parameter change functions.
In a preferred embodiment of the invention, the removable capture means (4A) is constructed of composite material .
In a preferred embodiment of the invention, the omnidirectional wind-capture modular device (1) can conjugate several modules, creating a tower that will act as a reverse chimney, directing the wind flow from any direction to the rotors of each of the said modules.
In a further preferred embodiment of the invention, the device (1) will play the role of supplying power to a network inverter by simply inputting the parameters of that inverter, in order to take the most advantage of its operation.
