Definitions
- the invention relates to a device for establishing an electrical connection between a multiphase distribution network of a ship and a multi-phase shore-side supply network, with an electrical plug unit arranged on the ship side and an electrical coupling unit arranged on the shore for electrical contacting with the electric plug unit of the ship, wherein the on the electrical side disposed coupling unit along at least a portion of the ship is designed to run verfahrbar.
- the diesel engines are usually run for power generation even in ships anchored in the harbor.
- the diesel engines of container ships not only have a high fuel consumption, but also represent a significant environmental burden due to the nitrogen oxide and soot emissions. Due to stricter environmental protection laws and the fact that individual port operating companies plan the operation of marine diesel engines Shutting off power generation in the harbor means that the shore power supply of the ships anchored in the harbor is becoming more and more important, since shore-side electricity supplies can be used to switch off the diesel engines of the ships.
- the electrical plug unit In contrast to training on cruise ships, in which the electrical coupling unit is arranged on board the ship, the electrical plug unit is arranged on board the ship, usually in a container, and must be connected to a shore-side electrical coupling unit in container ships.
- the ship-side electrical plug unit consists of two electric cables wound up on a common cable drum and end-fitted with plugs. The two cables are unwound from a cable drum or wound up again.
- the containers with the electrical plug units can be arranged at different positions on the ship and also the mooring position of a ship on the quay wall varies, it is necessary, several of these equipped with the electrical coupling units pits in the To provide the quay wall. Transporting the cables lowered from the container vessel to an electrical coupling unit several meters away is extremely problematic since each plug weighs approx. 15 kg and each cable connected to the plugs weighs approx. 10 kg per meter per meter.
- this known device of the electrical coupling units in pits arranged in the quay wall is very complex from the point of installation and, moreover, associated with high investment costs.
- the system e-chain® reel is known by Igus GmbH, in which the land-side coupling unit is arranged on a movable trolley, which is connected via an attached cable chain with a shore-side supply network.
- the process of the rolling stock provided with the coupling unit along the side of a ship takes place by means of a separate vehicle, for example a forklift truck.
- the invention is based on the invention to provide a device for establishing an electrical connection between a multi-phase distribution network of a ship and a multi-phase shore supply network, which allows a fast, secure and flexible creation of electrical Kontak- t ist.
- the solution of this problem is inventively characterized in that the shore-side electrical coupling unit is rail-guided movable, wherein the shore-side electrical coupling unit has a receiving and guiding device for the wired connector of the electrical connector unit of the ship.

- the drive of the movable coupling unit is designed so that the rail system has at least one rack or pinion rail along which the coupling unit can be moved by means of at least one driven pinion.
- the spacing of individual rollers of the roller system in the direction of travel from one another is such that at least four rollers arranged in series one behind the other always have at least three rollers in contact with the rails or the anti-flooding wall. In this way, it is ensured that the movable coupling unit is always guided sufficiently stable even when crossing a gap in the rail system.
- the receiving and guiding device for each wired connector of the electrical connector unit has a semi-circular in cross-section guideway, each guideway has two at an angle to each other arranged portions which are interconnected by a radius.
- the two subregions of each guideway are arranged in a win angle of 70 ° to 110 °, that is substantially perpendicular to each other.
