Definitions

  • the present invention relates to an electrical power transmission system between one ore more pairs of conductors, particularly for electricity transmission to a propulsion and steering module for naval ships of the POD type.
  • the electrical power transmission between a power supply housed in the ship hull and a motor housed inside the pod of the propulsion and steering module is performed by means of a series of brushes integral to the ship frame, and therefore always fixed, and a series of conductive rings mounted on the propulsion and steering module stem, solidly rotating with it.
  • electrical power transmission can also be performed by means of brushes solidly rotating with the propulsion and steering module stem, and conductive rings integral to the ship frame, and therefore fixed.
  • the main task of the present invention is therefore to realize an electrical power transmission system between one or more pairs of conductors, which allows to obtain an optimal conduction, avoiding wear between brushes and contacts.
  • one object of the present invention is to provide an electrical power transmission system between one or more pairs of conductors which allows to avoid the forming of a coat due to oxidation phenomena facilitated by the marine environment.
  • Another object of the present invention is to provide an electrical power transmission system between one or more pairs of conductors, which can be used in propulsion and steering module naval ships.
  • an electrical power transmission system between one or more pairs of conductors characterised by the fact that it comprises a first sliding contact means connected to a first conductor of said one or more pairs of conductors, a second sliding contact means, connected to a second conductor of said one or more pairs of conductors, and a third sliding contact means in continuous relative motion in relation to said first and second sliding contact means.
  • FIG 1 shows a naval ship 1 on the hull of which a propulsion and steering module 2 of the POD type is mounted, comprising a pod 40 and a support 50, electrically fed by means of the electrical power transmission system 3.
  • Figure 2 and 3 show a preferred embodiment of the electrical power transmission system.
  • a pair of conductive cables 6 and 14 are connected to, respectively, a first sliding contact means 7 and a second sliding contact means 25 of the electrical power transmission system according to the invention.
  • the second sliding contact means are electrically insulated from the stem 5 by insulating means 13. Between the brushes 7 and the graphite rings 12, a third sliding contact means 8 are provided, fixed on the support means 10 and electrically insulated by insulating means 9.
  • the sliding contact means 8 are made of rotating conductive rings and the support means 10 are made of a rotating roll holding rings.
  • the first sliding contact means 7 can be made of graphite rings, and the graphite rings 12 can be made of brushes.
  • the rotating roll 10 can be realised with metallic material or plastic-composite material thus making the insulating means 9 useless.
  • the supporting means 10 can be made of a set of rotating stems holding the rings or the brushes.
  • Driving and guiding means 17 directly operate on said rotating roll 10, comprising in the illustrated embodiment, a motor 16 driving a gear 18-pinion 15 system and a sliding guide 20.
  • the guide 20 can be made of a circular rail, or anyway of sliding means facilitating the rotation of the roll 10.
  • the electric motor 16 acts on the gear 18-pinion 15 system which operates on the rotating roll 10, making it rotate inside the guide 20. In this way, being the rotating rings 8 constrained to said roll 10, they also rotate generating a continuous sliding contact, both with the brushes 7 and the graphite rings 12, along all the surface of the rotating ring 8 itself, even when the ship navigates at cruise speed, and the propulsion and steering module is fixed in relation to the ship hull.
  • a particular application of the electrical power transmission system according to the invention occurs when a propulsion and steering module for naval ships comprising a submerged watertight pod, inside which an electric motor is housed, and a substantially vertical support, the bottom part of which is joined to the pod and the top part of which is connected to the hull of said naval ship in such a way as to be able to rotate in relation to the longitudinal axis of the hull and inside which electronic power and control modules are housed.
  • the power supply between the fixed part (hull) and the mobile part (pod and support) conveniently occurs by means of two direct current conductors only, and, as a consequence, the electrical power transmission system according to the invention comprises two rotating conductive rings only.
  • the power supply between the fixed part (hull) and the mobile part (pod and support) occurs by means of alternate current, and the number of conductors ranges accordingly from 3 to 8, in case of synchronous motor, asynchronous motor, three-phase motor, or hexa phase motor; as a consequence, the electrical power transmission system also comprises a number of rotating conductive rings ranging from 3 to 8.
  • the electrical power transmission system as conceived is capable of numerous modifications and variants that are all within the inventive concept; moreover all the details may be substituted by other technically equivalent elements.
  • the dimensions and materials used can be of any kind to suit the requirements of the state of technology, providing they are compatible with the specific use.
