Abstract
Description
[0001] This application is a divisional application of the invention patent application with application number 202080037619.3, application date April 23, 2020, and invention name “Device for supplying consumers”. Technical Field
[0002] The invention relates to a device for supplying a consumer with energy from a fixed-position supply, the position of which consumer cannot be determined exactly at first but can subsequently be arranged essentially fixedly, the device comprising a movable carriage or slide, which is connected to an arm that can be moved between a first position and a second position, the arm having at least one plug element for connection to an energy supply line of the consumer, wherein the plug element is connected to the supply via the energy supply line. Background Art
[0003] Such a device is known from WO 2012 / 116919 A1. This device relates to an energy supply device for a ship located at a ship berthing position in a port. The guide device has a horizontally movable slide arranged on land, on which an energy supply line with a plug piece is arranged to supply the ship with electrical energy. In this case, the energy supply line can be electrically connected to the energy supply network on the land side. The plug-side section of the energy supply line is arranged on the slide so as to be vertically movable by an arm.
[0004] By means of a horizontally movable carriage or slide, the section of the energy supply line provided with a plug piece can be variably arranged, for example, along the ship docking position and also along the ship located at the ship docking position. Thus, the section of the energy supply line provided with a plug piece can be moved to the position of the ship docking position, where the section is needed for the ship located there respectively. Therefore, this is particularly advantageous, because the ship docking position in the port can dock the most different ships, which differ, for example, in their size and structure. In each of these ships, an energy supply line guided from the consumer with a plug piece will be needed at other positions along the ship docking position. By means of a slide that can be moved on a suitable guide device (the guide device can also receive the section on the supplier side of the energy supply line), it is avoided that the section on the supplier side of the energy supply line is located loosely and unprotected on the ship docking position or next to it on a distant section.
[0005] The connection of the plug piece (connected to the energy supply line of the supplier) to the energy supply line of the consumer is subject to the risk of arc ignition and thus explosion due to the high voltage applied, as a result of which hot gases can escape into rooms used by people and / or containing flammable objects. In particular, such an arc explosion can endanger people and flammable objects (such as vehicles) that are located on the dock equipment at the ship's berth. Summary of the invention
[0006] The object of the present invention is therefore to provide a device of the type mentioned above for supplying a consumer, which largely protects a dangerous space for people and flammable objects from the consequences of a possible arc ignition between a plug piece (of an energy supply line on the supplier side) and an energy supply line on the consumer side (connected to the plug piece).
[0007] According to the invention, this object is achieved in the following way: a cover part that can move with the movement of a movable arm connected to a movable sliding frame or slide is arranged, and the cover part at least partially covers the plug part in a first position of the arm and exposes the plug part in a second position of the arm for connection to an energy supply pipeline on the consumer side.
[0008] By means of a cover part whose movement is coupled to the movement of the arm, hazardous spatial areas (for example on a docking station at a ship's berth) can be shielded from possible arc ignition at the connection point between the plug part and the energy supply line on the consumer side.
[0009] In the first position of the arm, the arm can be in a supply position in which the plug piece is not connected to the energy supply line on the consumer side. In this position of the arm, the carriage or the slide can be moved into a position in which the consumer is present and the energy supply line on the consumer side can be fed to the device for supplying the consumer. Starting from this first position, the arm connected to the carriage or the slide can be moved into its second position in which the cover exposes the plug piece, whereby the energy supply line on the consumer side can be connected to the plug piece. After the energy supply line on the consumer side has been connected to the plug piece, the arm with the energy supply line on the consumer side can be moved from its second position into the first position in which the cover at least partially covers the plug piece. In this position, the arm is in its operating position in which the consumer can be supplied with energy by a fixed supply.
[0010] In the first position of the arm, the cover can be arranged on the arm in such a way that it covers the plug element in a direction pointing away from the consumer and preferably also in both directions of the movement path of the carriage or slide.
[0011] In the second position of the arm, the arm is preferably arranged so that the plug piece is easily accessible to an operator who is located on a fixed base surface, relative to which the slide or carriage can be moved, so that the operator can connect a consumer-side energy supply line with a greater weight and thickness to the plug piece in a particularly simple manner.
[0012] The cover can have a wall directed away from the consumer, with which the cover covers the plug piece in the first position of the arm. Furthermore, the cover has, on its wall directed away from the consumer, a subsequent side wall directed in the direction of the movement path of the carriage or carriage, which side wall, together with the wall directed away from the consumer, covers the plug piece in the first position of the arm.
[0013] In the first position of the arm, the cover can be locked on the arm.
[0014] The movement of the cover can be coupled to the movement of the arm between its first and second position, in particular by means of a mechanical coupling between the cover and the arm.
[0015] In a preferred embodiment of the invention, the arm can be pivoted between its first position and its second position, wherein the pivot axis can be arranged horizontally and parallel to the displacement path of the carriage or slide.
[0016] The sliding frame or slide can be arranged in a shaft in a fixed base surface (for example, a pier) so that the arm connected to the sliding frame or slide can be arranged in its second position essentially horizontally, but at an angle of at least less than 30°, in particular less than 20°, to the horizontal line in order to enable an operator to easily reach the plug piece.
[0017] If it is an energy supply device for a ship located at a berth in a port, the carriage or slide is preferably arranged in a guide device mounted on the quay wall on the ship side, so that the arm connected to the carriage or slide can also be arranged in its second position essentially 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 the operating personnel.
[0018] In the first position of the arm, the arm can be swung upwards from its second position so that the plug element is arranged higher than in the second position of the arm. In its first position, the arm can be arranged at an angle of more than 60°, in particular more than 70°, to the horizontal. In this position, the carriage or carriage together with the arm occupies a relatively small space extending horizontally and perpendicularly to the movement path of the carriage or carriage. Thus, on a fixed base surface (e.g. of a dock installation), the carriage or carriage together with the arm in its first position occupies a relatively small space which hardly restricts the freedom of movement of persons and vehicles located there.
[0019] In a preferred embodiment of the invention, the cover can be designed as a cap which is pivotable on the arm about an axis parallel to the pivot axis of the arm, wherein the axis is arranged at a distance from the plug element in the direction of the free end of the arm.
[0020] In the preferably substantially vertical position of the arm in its first position, the cover can also be in a vertical pivot position. The wall pointing away from the consumer and the side walls of the cover pointing in the direction of the movement path of the carriage or slide can also extend vertically.
[0021] By coupling the pivoting movement of the cover with the pivoting movement of the arm, the cover can be pivoted away from the arm when the arm is pivoted from its first position to the second position, so that the plug element is exposed in the second position of the arm. The cover can also be in a vertical position in the second position of the arm.
[0022] The arm and the cover can be designed such that the cover, in the second position of the arm in which the cover is pivoted away from the arm, rests on a stationary base surface (eg, of a dock installation at a ship's berth).
[0023] The cover can have a preferably substantially rectangular wall pointing away from the consumer and side walls adjoining the wall laterally pointing in the direction of the travel path of the carriage or carriage, preferably substantially rectangular. In this case, the cover can protect the critical spatial area away from the consumer and laterally from the consequences of an arc explosion in the connection area between the plug piece and the energy supply line on the consumer side. When using the device according to the invention to supply energy to a ship at a dock facility in a port, this design of the cover provides protection perpendicular to the travel path of the carriage or carriage towards the dock facility and in both directions of the travel path.
[0024] In the second position of the arm, the wall pointing away from the consumer and (if necessary) the side wall of the cover can be arranged essentially perpendicular to the arm.
[0025] The cover can be coupled to the arm via a lever mechanism in such a way that the cover is swiveled synchronously with the arm as a result of the swiveling movement of the arm between its first and second position.
[0026] For this purpose, the lever mechanism can have a connecting rod which is pivotably arranged in one of its end regions on the cover and pivotably arranged in its other end region on a lever arm which is fixedly connected to the carriage or the slide and is oriented away from the consumer.
[0027] A cable duct extending along the arm, in which cable duct at least one energy supply line is arranged in the region of the arm, can be arranged on or in the arm.
[0028] The arm can be of plate-shaped design, wherein the cable duct is arranged on the arm.
[0029] In particular, a cable duct can be arranged in each case in the region of one of the two longitudinal sides of the arm.
[0030] The cable duct can be designed to be flexibly flexible in the pivoting direction at least in the region of the pivoting connection of the arm to the carriage or slide.
[0031] In the region of the free end of the arm a housing can be arranged, into which the energy supply line on the supply side is led and to a plug piece protruding on the housing in the direction of the consumer. The cable channel can end at the housing.
[0032] In the first position of the arm, the cover can terminate with the housing on the side oriented away from the consumer, the side pointing in the direction of the movement path of the carriage or carriage and the side pointing away from the carriage or carriage. Thus, in the first position of the arm, the cover with the housing forms a largely closed cover of the plug piece in the direction pointing away from the consumer and in the lateral direction of the movement path of the carriage or carriage and in the direction of the arm pointing away from the carriage or carriage. Thus, the hot gases generated by the arc ignition can be discharged into a non-hazardous space.
[0033] A cover part designed as a lid can be mounted on the housing in a pivotable manner.
[0034] The energy supply line on the feeder side can be laid in at least one energy guide chain in the area between the fixed feeder and the carriage or slide, the energy guide chain having a first joint fixed in position relative to the feeder and a second joint arranged on the carriage or slide, from which the energy supply line is guided via at least one cable channel to a pivotable arm.
[0035] The energy transmission chain can have a first section connected to a first connection and a second section connected to a second connection, wherein the first section and the second section are connected to each other via a deflection region. The two sections are arranged one above the other, wherein the lower section is preferably connected to the first connection and the upper section is preferably connected to the second connection.
[0036] The energy guide chain can be arranged in a particularly trough-shaped guide device. When using the device according to the invention for ships located on a quayside facility in a port, the guide device with the energy guide chain can be arranged on the side of the quayside wall facing the ship.
[0037] Alternatively, the guide device with the energy guide chain can also be arranged in a shaft arranged in a fixed base (for example, a dock equipment of a port), relative to which the carriage or slide can be moved. The guide device can also be arranged on a fixed base (for example, a dock equipment of a port). BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 2 :according to Figure 1 A three-dimensional top view of a device for supplying a consumer, wherein the arm connected to the carriage or the slide is in its second position, and
[0041] Figure 3 :according to Figure 1 A three-dimensional top view of a device for supplying consumers, wherein the arm connected to the carriage or slide is in its first position. DETAILED DESCRIPTION
[0042] As can be seen from the drawing, a device 1 for supplying a consumer (not shown in the drawing) comprises a movable carriage or slide 2, the position of which cannot initially be determined exactly but which can subsequently be arranged substantially fixedly, which is connected to a pivotable arm 3. The arm has at least one plug piece 4 for connection to an energy supply line 5 of the consumer, wherein the plug piece 4 is connected to a stationary supply (not shown in the drawing) via an energy supply line 6.
[0043] Especially from Figure 1 It can be seen that the arm 3 connected to the carriage or slide 2 can be pivoted between a first position 7 and a second position 8. On the arm 3, in the region of its free end, a cover 9 is arranged which can pivot with the pivoting movement of the arm 3, the pivoting movement of the cover being coupled to the pivoting movement of the arm 3, more precisely in such a way that the cover 9 at least partially covers the plug element 4 in the first position 7 of the arm 3 and exposes the plug element 4 in the second position 8 of the arm 3 for connection to the energy supply line 5 on the consumer side.
[0044] The carriage or slide 2 can be perpendicular to Figure 1 The arm 3 connected to the carriage or slide 2 can be pivoted about an axis which is arranged parallel to the movement path of the carriage or slide 2. As can also be seen from the figures, the arm 3 is arranged essentially vertically in its first position 7 and essentially horizontally in its second position 8.
[0045] In the swingable arm 3 Figure 1 In the intermediate position shown in FIG. , the energy supply line 5 on the consumer side is not drawn in for reasons of clarity of the drawing.
[0046] In the embodiment under consideration, the arm 3 can be pivoted by a hydraulic drive 10 which acts in an articulated manner on a roof-like covering device 11 of the carriage or slide 2 and is arranged on a fork-shaped web 12 which is arranged on the arm 3 in its end region opposite the free end.
[0047] The cover 9 is designed as a cap 13 which can be pivoted 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 plug piece 4 in the direction of the free end of the arm 3. As can be seen from the figure, the cover 13 has a substantially rectangular wall 14 pointing away from the consumer and substantially rectangular side walls 15, 16 adjoining the wall laterally pointing in the direction of the movement path of the carriage or carriage 2. The cover can thus be moved away from the consumer and laterally protect a critical space region from the consequences of a possible arc explosion in the connection region between the plug piece 4 and the energy supply pipe 5 on the consumer side, which, according to the figure, is a quayside installation for ships (consumers) moored there.
[0048] In the vertical position of the arm 3 in its first position 7, the cover 13 is also in its vertical pivoted position, wherein the wall 14 of the cover 13 pointing away from the consumer and the side faces 15, 16 pointing in the direction of the movement path of the carriage or carriage 2 also extend vertically. Figure 1 As is known, the cover 13 is coupled to the arm 3 via a lever mechanism 17 so that the cover is swiveled synchronously with the swiveling movement of the arm 3 between its first position 7 and its second position 8. The lever mechanism 17 has a connecting rod 18 which is swiveled in one of its end regions on the cover 13 and in its other end region on a lever arm 19 which is fixedly connected to the carriage or slide 2 and is directed away from the consumer.
[0049] As especially Figure 2 and 3 As shown, the arm 3 is of plate-shaped design, wherein the respective cable duct 20 is located in the region of one of the two longitudinal sides of the plate-shaped arm 3 , in which the arm-side region of the energy supply line 6 is arranged in each case.
[0050] Especially from Figure 2 and 3 It is apparent that the two cable ducts 20 are designed to be flexibly flexible in the pivoting direction of the arm 3 .
[0051] In the region of the free end of the arm 3 a housing 21 is arranged, in which the cable duct 20 ends and in which the region of the energy supply line 6 arranged therein is guided to the plug piece 4 which protrudes on the housing 21 in the direction of the consumer.
[0052] The cover 13 is supported on the housing 21 in a swingable manner. Figure 3 As shown in the figure, the cover 13 in the first position 7 of the arm 3 ends with the housing 21 on the side oriented away from the consumer, the side pointing in the direction of the movement path of the carriage or carriage 2 and the side pointing away from the carriage or carriage 2, without any significant intermediate space between the cover 13 and the housing 21 on these sides, through which hot gases generated in the event of a possible arc ignition could escape in the mentioned direction. Such hot gases generated by the arc ignition can thus be discharged into a non-hazardous space, in the present embodiment between the quay wall 22 and the ship (not shown in the figure). It can be seen that in this embodiment, the ship is spaced so far from the quay wall 22 by the folding element (not shown in the figure) that the carriage or carriage 2 and its guide cannot be touched by the ship.
[0053] The energy supply line 6 on the supply side is laid in an energy guide chain 23 in the region between the stationary supply and the carriage or slide 2, which has a first connection (not shown in the drawings) arranged stationary relative to the supply and a second connection 24 arranged on the carriage or slide 2, from which the energy supply line 6 is guided through at least one cable channel 25 toward the pivotable arm 3. The energy guide chain 23 has a lower section 26 connected to the first connection and an upper section 27 connected to the second connection 24, which are connected to each other via a deflection region. The energy guide chain 23 is arranged in a guide groove 28, which also guides the carriage or slide 2 connected to the second connection 24 along its travel path on rollers 29. The guide groove is arranged stationary on a bracket 30 on the quay wall 22.
[0054] Due to the guide groove 28 fastened laterally to the quay wall 22 and the carriage or carriage 2 arranged thereon, the pivot axis of the arm 3 is arranged relatively low relative to the base surface 31 of the quay, so that the arm 3 is easily accessible to an operator located on the quay with the plug piece 4 in its substantially horizontal second position. In the second position 8 of the arm 3, the cover 13 is supported on the base surface 31 of the quay by one or more supporting elements 32. The plug piece 4 can be connected to the energy supply line 5 on the consumer side by the operator and this connection can be locked by a locking mechanism 33. Likewise, after the energy supply to the consumer has ended, in the second position 8 of the arm 3, the energy supply line 5 on the consumer side can be released from the plug piece 4 by releasing the locking mechanism.
[0055] Furthermore, locking devices (not shown in the drawings) are provided on the arm 3 and the cover 13, by means of which the cover 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 plug piece 4 and the energy supply line 5 on the consumer side connected to the plug piece 4, the cover 13 cannot swing upwards due to the explosion pressure.
