Description

[0001] The invention relates to a device for supplying a consumer, for example a ship, whose position cannot initially be determined precisely but can later be determined to be essentially stationary, for example on a harbor quay, with energy from a stationary supplier, with a movable carriage or slide which is connected to an arm which is movable between a first position and a second position and which has at least one plug-in connector part for connection to a first energy supply line, the energy supply line of the consumer, wherein the plug-in connector part is connected to the supplier via a second energy supply line.

[0002] A device for supplying a consumer is known from WO 2012 / 116919 A1. This device is a power supply device for a ship moored at a berth in a harbor. The guide device comprises a horizontally movable carriage arranged on land, to which a power supply line provided with a plug connector part is arranged for supplying the ship with electrical power. The power supply line is electrically connectable to a shore-based power supply network. A plug-side section of the power supply line is arranged on the carriage so that it can be moved vertically via an arm.

[0003] With the horizontally movable carriage or sled, the section of the supplier-side power supply line equipped with the connector can be variably positioned, for example, along the ship's berth and also along a ship berthed at the berth. This allows the section of the supplier-side power supply line equipped with the connector to be moved to the location of the berth where it is needed for the ship berthed there. This is particularly advantageous because a wide variety of ships can dock at a port's berth, differing, for example, in size and design.The carriage, which can be moved on a suitable guide device which can also accommodate the section of the supplier-side power supply line provided with the connector part, prevents the supplier-side power supply line from lying loose and unprotected over long distances on or at the ship's berth.

[0004] Due to the high voltage applied, connecting the connector part connected to the supplier's power supply line to the consumer's power supply line poses the risk of arc ignition and a resulting explosion, which could cause hot gases to escape into a space occupied by people and / or containing flammable objects. In particular, such an arc explosion can endanger people and flammable objects, such as vehicles, on the quayside of a ship's berth.

[0005] The present invention is therefore based on the object of proposing a device for supplying a consumer, in particular a ship, with energy from a stationary supplier which is technically improved compared to the prior art.

[0006] Furthermore, a device for supplying a consumer of the above-mentioned type should preferably be provided which largely protects a space at risk for persons and flammable objects from the effects of a possible arc ignition between the plug-in connector part of the second, supplier-side power supply line and the first, consumer-side power supply line connected to the plug-in connector part and at the same time considerably facilitates handling for operators.

[0007] The object is achieved by the subject matter of independent claims 1, 13 and 26. Preferred embodiments are specified in the subclaims.

[0008] In the first position of the arm, the arm can be in a ready position in which the connector part is not connected to a first, consumer-side power supply line. With this position of the arm, the carriage or slide can be moved to the location where the consumer is located and the first, consumer-side power supply line can be fed to the device for supplying the consumer. From this first position, the arm connected to the carriage or slide can be moved to its second position in which the first, consumer-side power supply line can be connected to the connector part. After the first, consumer-side power supply line has been connected to the connector part, the arm with the first, consumer-side power supply line can be moved from its second position to the first position.In this position, the arm is then in its operating position, in which the consumer can be supplied with energy by the fixed supplier.

[0009] A cover part can be arranged on the arm in its first position so that it at least partially covers the connector part. The cover part can be used to shield a hazardous area, e.g., on a quayside at a ship's berth, against possible arcing at the connection point between the connector part and the consumer-side power supply line.

[0010] In its second position, the arm is preferably arranged such that the connector part is easily accessible to an operator located on a stationary base surface relative to which the carriage or slide is movable, so that he or she can easily connect, in particular, a first, consumer-side power supply line having a greater weight and thickness to the connector part.

[0011] The cover part can have a wall facing away from the consumer, which covers the plug part in the first position of the arm. Furthermore, the cover part can have side walls adjoining its wall facing away from the consumer, which side walls point in the direction of the carriage or slide's travel path. These side walls, together with the wall facing away from the consumer, cover the plug part in the first position of the arm.

[0012] The cover part can be locked to the arm in the first position.

[0013] The movement of the cover part can be coupled to the movement of the arm between its first and second position, in particular by a mechanical coupling between the cover part and the arm.

[0014] In a preferred embodiment of the invention, the arm is pivotable between its first position and its second position, wherein the pivot axis can be arranged horizontally and / or parallel to the travel path of the carriage or slide.

[0015] The carriage or sledge can be arranged in a shaft in the stationary base area, e.g. a quay, so that the arm connected to the carriage or sledge can be arranged in its second position substantially horizontally, but at least at an angle of less than 30°, in particular less than 20°, relative to the horizontal, for the purpose of easy accessibility of the connector part by an operator.

[0016] If it is an energy supply device for a ship lying at a berth in a port, the carriage or sledge is preferably arranged in a guide device attached to the ship's side on the quay wall, so that the arm connected to the carriage or sledge can also be arranged in its second position substantially horizontally, but at least at an angle of less than 30°, in particular less than 20°, to the horizontal at a height above the quay that is easily accessible to an operator.

[0017] In its first position, the arm can be pivoted out from its second position such that the connector part is arranged higher than in the second position of the arm. In its first position, the arm can be arranged at an angle greater than 60°, in particular greater than 70°, to the horizontal. In this position, the carriage or slide, together with the arm, takes up a relatively small space extending horizontally and perpendicular to the travel path of the carriage or slide. On the stationary base surface, e.g. a quay, the carriage or slide, together with the arm in its first position, therefore takes up a relatively small space that hardly restricts the freedom of movement of people and vehicles located there.

[0018] In a preferred embodiment of the invention, the cover part can be designed as a flap that can be pivoted on the arm about an axis parallel to the pivot axis of the arm. The axis can, in particular, be arranged at a distance from the connector part toward the free end of the arm.

[0019] When the arm is in its first position, preferably approximately vertical, the flap can also be in a vertical pivot position. The wall facing away from the consumer and the side walls of the flap facing in the direction of travel of the carriage or slide can then also be vertical.

[0020] For example, by coupling the pivoting movement of the flap with the pivoting movement of the arm, the flap can be pivoted away from the arm when the arm pivots from its first position to the second position, so that the connector part is exposed in the second position of the arm. The flap can also be in a vertical position in the second position of the arm.

[0021] The arm and the flap can be designed in such a way that the flap, in the second position of the arm in which it is pivoted away from the arm, is supported on a stationary base surface, e.g. the quay of a ship's berth.

[0022] The flap can have a preferably substantially rectangular wall facing away from the consumer and laterally adjoining, preferably substantially rectangular, side walls facing in the direction of the carriage or sled's travel path. The flap can then protect a vulnerable spatial area away from the consumer and laterally from the effects of an arc explosion in the connection area between the connector part and the consumer-side power supply line. When the device according to the invention is used to supply power to a ship moored at a quay in a port, this design of the flap provides protection perpendicular to the carriage or sled's travel path toward the quay and in both directions of the travel path.

[0023] The wall facing away from the consumer and, where appropriate, the side walls of the flap may be arranged substantially perpendicular to the arm in the second position of the arm.

[0024] The flap can be coupled to the arm by a lever mechanism, in particular in such a way that it is pivoted simultaneously by the pivoting movement of the arm between its first and second position.

[0025] For this purpose, the lever mechanism can have an articulated rod which is pivotally mounted on the flap in one of its end regions and pivotally mounted on a lever arm which is fixedly connected to the carriage or slide and points away from the consumer in its other end region.

[0026] A cable duct extending along the arm can be arranged on or in the arm, in which the at least one power supply line is arranged in the region of the arm.

[0027] The arm can be plate-shaped, with the cable duct arranged on the arm.

[0028] In particular, a cable duct can be arranged in the area of ​​one of the two long sides of the arm.

[0029] The cable duct can be designed to be flexible in the pivoting direction, at least in the area of ​​the pivoting connection of the arm to the carriage or slide.

[0030] A housing can be arranged on the arm, particularly in the area of ​​the free end of the arm, into which the power supply cable from the supplier is inserted and led to a connector part provided on the housing, particularly one that protrudes toward the consumer. The cable duct can end at the housing.

[0031] In the first position of the arm, the cover part can be flush with the housing on the side facing away from the consumer, the sides facing in the direction of the carriage or slide's travel path, and the side facing away from the carriage or slide. Thus, in the first position of the arm, the cover part with the housing can form a largely closed cover of the connector part in the direction facing away from the consumer, as well as in the lateral direction of the carriage or slide's travel path and in the direction of the arm facing away from the carriage or slide. Hot gases generated by arc ignition can thus be diverted into a safe space.

[0032] The cover part designed as a flap can be pivotably mounted on the housing.

[0033] The second, supplier-side power supply line can be laid in an area between the stationary supplier and the carriage or slide in at least one energy guide chain, which has a first connection arranged stationary relative to the supplier and a second connection arranged on the carriage or slide, from which the power supply line is guided via at least one cable duct to the pivotable arm.

[0034] The energy guiding chain can have a first strand connected to the first connection and a second strand connected to the second connection, which are connected to each other via a deflection region. The two strands can be arranged one above the other, with the lower strand preferably connected to the first connection and the upper strand preferably connected to the second connection.

[0035] The energy guiding chain can be arranged in a guide device, particularly one that is trough-shaped. When using the device according to the invention for a ship moored at a quay in a port, the guide device with the energy guiding chain can be arranged on the side of the quay wall facing the ship.

[0036] Alternatively, the guide device with the energy guide chain can also be arranged in a shaft provided in a stationary base, relative to which the carriage or sled is movable, e.g., a quayside at a port. The guide device can also be arranged on the stationary base, e.g., a quayside at a port.

[0037] An embodiment of the present invention is described in more detail below with reference to the drawing. In the drawing: Fig. 1: a frontal plan view of a device for supplying a consumer, wherein the arm connected to the carriage or slide with the connector part is in its second position, with the first position and an intermediate position shown in dashed lines, Fig. 2: a perspective top view of the device for supplying a consumer according to Fig. 1, wherein the arm connected to the carriage or slide is in its second position, and Fig. 3: a perspective top view of the device for supplying a consumer according to Fig. 1, with the arm connected to the carriage or slide in its first position.

[0038] As can be seen from the drawing, the device 1 for supplying a consumer (not shown in the drawing), whose position cannot initially be precisely determined but can later be essentially fixed, comprises a movable carriage or slide 2 connected to a pivotable arm 3. The arm has at least one connector part 4 for connection to a power supply line 5 of the consumer, wherein the connector part 4 is connected to the stationary supplier (not shown in the drawing) via a second power supply line 6.

[0039] As is particularly evident from Fig. 1, the arm 3 connected to the carriage or slide 2 is pivotable between a first position 7 and a second position 8. In the example shown, a cover part 9 is arranged on the arm 3 in the region of its free end, which cover part 9 can be pivoted with the pivoting movement of the arm 3, the pivoting movement of which cover part 9 is coupled to the pivoting movement of the arm 3 in such a way that the cover part 9 at least partially covers the plug connector part 4 in the first position 7 of the arm 3 and the plug connector part 4 is exposed in the second position 8 of the arm 3 for connection to the consumer-side power supply line 5.

[0040] The carriage or slide 2 is perpendicular to the drawing plane of the Fig. 1 is movable in both directions. The axis about which the arm 3 connected to the carriage or slide 2 is pivotable is arranged parallel to the travel path of the carriage or slide 2 in the example shown. As can also be seen from the drawing, the arm 3 is arranged essentially vertically in its first position 7 and essentially horizontally in its second position 8.

[0041] At the Fig. In the intermediate position of the pivotable arm 3 shown in Figure 1, the first energy supply line 5 on the consumer side is not shown for the sake of clarity of the drawing.

[0042] In the exemplary embodiment considered, the arm 3 can be pivoted via a hydraulic drive 10 which engages in an articulated manner on a hood-shaped cover 11 of the carriage or slide 2 and on a fork-shaped web 12 arranged on the arm 3 at its end region opposite the free end.

[0043] The cover part 9 is designed as a flap 13, which is pivotable on the arm 3 about an axis parallel to the pivot axis of the arm 3, wherein the axis is arranged at a distance from the connector part 4 in the direction of the free end of the arm 3. As can be seen from the drawing, the flap 13 has a substantially rectangular wall 14 facing away from the consumer and, laterally adjoining it, substantially rectangular side walls 15, 16 facing in the direction of the travel path of the carriage or slide 2. The flap can thus protect a hazardous spatial area, which according to the drawing is a quay for a ship (consumer) to be berthed there, away from the consumer and laterally from the effects of a possible arc explosion in the connection area between the connector part 4 and the consumer-side power supply line 5.

[0044] In the vertical position of the arm 3 in its first position 7, the flap 13 is also in its vertical pivot position, with the wall 14 facing away from the consumer and the side surfaces 15, 16 of the flap 13 facing in the direction of travel of the carriage or slide 2 also running vertically. The flap 13 is in the Fig. 1, the arm 3 is coupled by a lever mechanism 17 such that it is simultaneously pivoted by the pivoting movement of the arm 3 between its first position 7 and second position 8. The lever mechanism 17 has a joint rod 18, which is pivotably mounted on the flap 13 in one of its end regions and pivotably mounted on a lever arm 19 that is fixedly connected to the carriage or slide 2 and points away from the consumer in its other end region.

[0045] As in particular the Fig. 2 and Fig. 3, the arm 3 is plate-shaped, with a cable duct 20 being located in the region of one of the two longitudinal sides of the plate-shaped arm 3, in each of which an arm-side region of the power supply line 6 is arranged.

[0046] The two cable ducts 20 are, as can be seen in particular from the Fig. 2 and Fig. 3, is designed to be flexible in the pivoting direction of the arm 3.

[0047] In the area of ​​the free end of the arm 3, a housing 21 is arranged, into which the cable ducts 20 end and the area of ​​the power supply line 6 arranged therein is guided to the connector part 4 projecting on the housing 21 in the direction of the consumer.

[0048] The flap 13 is pivotably mounted on the housing 21. As in Fig.3, in the first position 7 of the arm 3, the flap 13 closes with the housing 21 on the side facing away from the consumer, the sides facing in the direction of the travel path of the carriage or slide 2, and the side facing away from the carriage or slide 2 with the housing 21, without any significant gaps being created between the flap 13 and the housing 21 on these sides, through which hot gases generated in the event of a possible arc ignition can escape in the aforementioned directions. Such hot gases generated by an arc ignition can thus be diverted into a safe space, in the present example between the quay wall 22 and the ship (not shown in the drawing). It should be noted that in this example, the ship is spaced far enough from the quay wall 22 by means of folders (not shown in the drawing) that the carriage or slide 2 and its guide device are not touched by the ship.

[0049] The supplier-side power supply line 6 is laid in the area between the stationary supplier and the carriage or slide 2 in a power guide chain 23, which has a first connection (not shown in the drawing) fixed to the supplier and a second connection 24 arranged on the carriage or slide 2, from which the second power supply line 6 is guided via at least one cable duct 25 to the pivotable arm 3. The power guide chain 23 has a lower run 26 connected to the first connection and an upper run 27 connected to the second connection 24, which are connected to one another via a deflection region. The power guide chain 23 is arranged in a guide trough 28, which also guides the carriage or slide 2, connected to the second connection 24, along its travel path on rollers 29. The guide trough is fixedly arranged on brackets 30 on the quay wall 22.

[0050] Due to the guide channel 28 attached to the side of the quay wall 22 with the carriage or slide 2 arranged thereon, the pivot axis of the arm 3 is arranged relatively low with respect to the base surface 31 of the quay, so that the arm 3, in its second, substantially horizontal position with the connector part 4, is easily accessible to an operator located on the quay. In the second position 8 of the arm 3, the flap 13 rests on the base surface 31 of the quay with one or more support elements 32. The connector part 4 can be connected by the operator to the consumer-side first power supply line 5, and the connection can be locked by a locking mechanism 33. Likewise, after the power supply to the consumer has been terminated, the consumer-side first power supply line 5 can be detached from the connector part 4 in the second position 8 of the arm 3 by releasing the lock.

[0051] Furthermore, a locking device (not shown in the drawing) is provided on the arm 3 and the flap 13, with which the flap 13 can be locked to the arm 3 in the first position 7 of the arm 3, so that in the event of an arc explosion between the connector part 4 and the consumer-side first power supply line 5 connected to the connector part 4, the flap 13 cannot be swung open by the explosion pressure.
