Description

description

Energy supply facility On ships in ports, the electrical energy required on board is usually generated by onboard diesel generator sets. When operating these diesel generator sets, considerable quantities of diesel exhaust gases are generated, which contain, among other things, carbon dioxide and nitrogen oxides and are harmful to the environment.

Currently, there are considerations to supply a ship lying in the harbor by means of a flexible power supply line, a so-called hawser line, from the country with electrical energy (shore power). This electrical energy (electric power) is by means of a port located in the electrical energy supply network

provided and transmitted by means of the hawser / line to the ship. It can be one with a plug

provided end of the hawser line / line from aboard the

Ship to be handed over to the country

To connect the hawser line / line on land with the power supply network. The invention has for its object to provide a device with which a power supply line of the

Ship can be easily and safely connected to a power grid. This object is achieved by a

Energy supply device according to claim 1.

Advantageous embodiments of such

Energy supply device are in the dependent

Claims specified.

This power supply device for a on a

Shipyard of a port lying ship, in particular for a container ship, has a land arranged (stationary, fixed) stand on which at least one electrical contact means for a plug a

Power supply line of the ship is arranged, wherein the contact means is electrically connected to a landside

Power supply network is connected or connected and the contact means on the stand horizontally displaceable

is arranged. In particular, the contact means on the stand is horizontal along the ship berth

slidably arranged. This is in particular

advantageous that the contact means (for example, an electrical socket or socket) along the

Schiffsanlegeplatzes and thus along on the

Ship berth lying ship is arranged slidably. As a result, the contact agent to the point of

Mooring berth are moved to where it is needed for each ship there. This is

especially advantageous because at one

Ship berth of a harbor the most diverse

Ships can create, so z. B. Ships

different size and design. From each one of these

Ships out of the power line with the

Plugs are transferred to another location of the ship berth towards the land. By moving the

Contact agent is to the respective transfer point

successfully avoided that the plugged end of the power supply line to shore over wide

Distances must be transported to a suitable contact means. Rather, the contact agent is transported or moved to the point at which the

Power supply line leaves the ship. This advantage becomes particularly clear when one considers that the energy supply lines are preferably

Highly flexible medium voltage lines or

Medium voltage cable is, which often have a mass in the order of about 15 kg per meter in length. Therefore, it is associated with considerable effort, one transport such heavy energy supply line over long distances of the port area. In addition, such lying over long distances of the port area energy supply line is a significant source of danger because the energy supply line, for example, approached by driving in the harbor vehicles and thereby damaged or because pedestrians on the

Power supply line can trip. By the

horizontal displacement of the contact agent along the ship berth is achieved that the

Power supply line can be laid in the shortest possible way to the contact means, namely, e.g. at right angles from the longitudinal outer wall of the

Ship to the pushed to this point contact means.

The energy supply device can advantageously be designed so that the contact means is additionally arranged vertically displaceable. As a result, the contact means may also be vertically, e.g. pushed to the height at which the power supply line leaves the ship. This ensures that the power supply line between the point where it leaves the ship, and the

Contact must travel only a very short way. In addition, the power line can be routed over the heads of dock workers or on vehicles moving around the ship berth hanging, which accident risks are largely excluded.

The power supply device can also be designed so that on the stand a roof to protect the

Contact agent is arranged from the weather.

This roof protects the contact agent, in particular from rain, snow and moisture and from associated corrosion or short-circuit hazards. The power supply device can be realized in such a way that a horizontally movable carriage (drive slide, slide) for moving the contact means is arranged on or on the stand. By means of this carriage, the contact means can be moved to almost any desired position along the stand.

The power supply device can also be designed so that the contact means is attached to the carriage. In this case, the contact means is conveyed by the car safely and reliably to the desired location or

postponed .

The power supply device can be realized so that on or on the stand an electrical cable to

Connection of the contact means is arranged with the power supply network. Here is the electrical cable

advantageously arranged on or on the stand and not on the ground of the port area, where it could form a risk of accident.

The power supply device can also be designed so that the cable is guided within a chain (chain of cables), which consists essentially of movably connected chain links and which limits the minimum bending radius of the cable during movement of the carriage. The leadership of the cable in such a chain provides a mechanical

Protection for the cable and also limits the minimum bending radius of the cable, so that the cable can not be unduly sharply bent when moving the contact means; This will prevent damage to the cable.

The power supply device can be designed such that the cable is arranged on or on the stand at a height of between 2 and 8 meters (above the ground). A cable arranged at this height advantageously prevents neither workers walking around in the harbor nor people traveling around Vehicles, so that the safety is increased with respect to collisions or damage to the cable.

The energy supply device can also be configured such that a plurality of contact means which are displaceable independently of one another (horizontally and / or vertically) are arranged on the stand. This advantageously results in a particularly flexible energy supply device. It is advantageous that along the stand on the

Ship berth e.g. can create several shorter ships or a longer ship and one for each ship

own, independently displaceable contact means for

Available. Ie. in each case, a contact means can be moved to the corresponding ship and the

Energy supply line of the corresponding ship to be connected to this contact means. As a result, the ship berth can be flexibly used for ships of different lengths, with several ships simultaneously at the same time

Can create mooring.

The power supply device can also be designed so that at least two common to the stand

slidable contact means and an independent of these displaceable further contact means are arranged. This embodiment of the energy supply device can advantageously be used in particular for ships of different energy requirements. So z. B. the

Power supply line of a small ship, which has a low demand for electrical energy to be connected to the other contact means, because a single contact means is sufficient to the required electrical

Transfer energy. However, if a large ship with a large demand for electrical energy on the

Mooring berth, then the case may occur that a single contact means is not able to transmit the required electrical power. In this case, advantageously, the two common displaceable contact means to the transfer point of

Power supply line of the large ship to be moved and the power supply line can (possibly with the aid of an adapter) with the two common

slidable contact means are connected. If the big ship has two power supply lines ashore

passes, the two plugs can this

Power supply lines with the two in common

slidable contact means are connected. As a result, it is possible to use uniform contact means for the entire power supply device, which can each transmit electrical powers up to a specific maximum value, for example up to 5 MVA of electrical power.

In the following the invention is based on a

Embodiment explained in more detail. This is in

Figure 1 is a schematic sectional view of a

Energy supply device with connected power supply line, in

Figure 2 is a view of the power supply device seen from a ship and in

Figure 3 shows an embodiment of a within a

Cable chain guided cable shown.

1 shows a schematic sectional view of a power supply device 1, to which a

Plug 3 a power supply line 5 of a ship 7 is connected. The ship 7 is at a

Mooring (mooring) 9 of a harbor moored. From this ship berth 9 only a section of the quay wall 9 is shown schematically. The ship 7 is located in the water 10 in front of the quay wall 9 and is connected in a known manner with the quay wall 9, for example by means of ropes and bollards. The ship 7 may in particular be a container ship.

On the quay wall 9 is a stand constructed in the

Embodiment two columns (support) 11, preferably steel columns, and arranged on these columns 11 platform 13 has. On the platform 13 of the stand are on rails horizontally movable carriage, of which in the embodiment, a first car

(Drive slide, carriage) 15 and a second car

(Drive slide, carriage) 17 are shown. On the first carriage 15, a first electrical contact means 19 is arranged, which is horizontally movable with the first carriage 15. In the first electrical contact means 19 is a socket, which with the plug 3 of the power supply line 5 of the ship. 7

corresponds. In the same way, a second electrical contact means 21 is disposed on the second carriage 17, which is horizontally movable with the second carriage 17. From the first electrical contact means 19 extends

electrical cable 25 via the first carriage 15 to a

Line chain 27, which runs along the longitudinal extent of the stator. This line chain 27 protects

Method of the first carriage 15, the electrical cable 25 and in particular prevents this cable 25 sharp

kinked and thereby damaged. The line chain 27 consists essentially of movably interconnected chain links and limited in the process of the car, the minimum bending radius of the cable 25. In the same way, the second contact means 21 is electrically connected to a further electrical cable 30, which from the second contact means 21 via the second Car 17 is guided to another line chain 32. The first carriage 15 and the second carriage 17 are equipped with wheels 35 which do not explicitly refer to FIG Run rails shown and allow the horizontal mobility of the carriage 15 and 17.

On the platform 13 of the stator a roof 37 is fixed, which serves to protect the first electrical contact means 19 and the second electrical contact means 21 and the carriage 15 and 17 from the weather.

The first electrical contact means 19 and the second

electrical contact means 21 are independently horizontally displaceable / movable, because the first electrical contact means 19 carrying the first carriage 15, the line chain 27 is assigned, while the second electrical contact means 21 carrying the second carriage 17, the line chain 32 is assigned. Consequently, the first carriage 15 and the second carriage 17 are independently horizontally displaceable / movable.

In Figure 2, the power supply device 1 is shown in a side view seen from the ship 7 from.

It is good to see in Figure 2 that the first

Contact means 19 by means of the first carriage 15, regardless of the other contact means to the stand horizontally

slidably arranged. At the first electric

Contact means is schematically illustrated an opening 20 for insertion of the plug 3.

The second electrical contact means 21 is mechanically connected to a third electrical contact means 50, wherein the third electrical contact means 50 is attached to a third carriage 52 and is supported by this. The second

Contact means 21 is jointly displaceable with the third contact means 50, d. H. the second contact means 21 can only together with the third contact means 50th

horizontally along the stand (ie, along platform 13). Furthermore, the power supply device 1 has a fourth electrical contact means 60, which is attached to a fourth carriage 62 and is supported by this. This fourth contact means 60 can be moved horizontally independently of the other contact means.

The third contact means 50 is supplied via a third cable 54 with electrical energy. This third cable 54 is - as described in connection with the figure 1 for the cables 25 and 30 - by means of a not shown line chain on the platform 13 movably installed or guided. In the same way, the fourth contact means 60 is supplied with electrical energy by a fourth cable 64. Also, this fourth cable 64 is movably guided on the platform 13 in an associated, not shown line chain.

The cables 25, 30, 54 and 64 may also be highly flexible cables (so-called cable lugs).

These cables are mechanically guided safely on the stand consisting of steel columns and platform (carrier system). The cables are therefore located outside the danger area of the quay and are thus damaged by the

Transport traffic on the quayside protected.

The right part of FIG. 2 shows how the cable 25, the second cable 30, the third cable 54 and the fourth cable 64 are lowered from the platform to the ground and connected to a cable junction box 70. In this case, the cables 25, 30, 54 and 64 can advantageously be lowered in the interior of one of the columns 11 from the platform to the ground, whereby the cables against contact and

Damages are arranged protected. Of the

Cable junction box 70 can also be arranged in the interior of the column 11 or integrated into the column 11. In the cable junction box, the cables 25, 30, 54 and 64 with one or more medium voltage cables 72 of a medium voltage power supply network 74 shown only schematically. The or the

Medium voltage cable 72 is in the harbor area in one

Teaching system or a cable shaft laid in the ground.

Together with the cables 25, 30, 54 and 64 can continue to control lines or fiber optic cable of the

Cable junction box 70 are led to the contact means 19, 21, 50 or 60 to a communication between

port facilities and the ship. Alternatively, instead of a cable box 70 also a transition sleeve can be used. By way of example, in the first contact means 19, the

horizontal displacement along the stand 11, 13 symbolized by an arrow 80. The others, too

Contact means 21, 50 and 60 are horizontally displaceable. Optionally, one or more / all of these contact means 19, 21, 50, 60 may additionally be designed to be vertically displaceable. This is indicated by way of example for the contact means 19 by means of an arrow 82. The vertical displaceability of the contact means can for example be achieved by e.g. the first contact means 19 is lowered or pulled up on the cable 25. The vertical one

Displaceability of the first contact means 19 can, however, alternatively also be achieved, for example, by connecting the first contact means 19 to the first carriage 15 by means of a scissors grid or cross linkage, not shown in FIG. 2, so that the first contact means 19 is obtained by extending or retracting this scissors grid can be moved downwards or upwards. Such a scissors lattice / cross linkage is also referred to as a Ruthmannsteiger and resembles an aerial work platform. In another embodiment, the vertical displaceability of the first contact means 19 can also be realized by means of hydraulics or electrically. The platform 13 of the power supply device 1 and thus extending in the cable chains cable 25, 30, 54 and 64 are arranged in the embodiment in a height of 4 meters above the ground. In general, the height of the platform 13 and thus the height of the cables between 2 and 8 meters above the ground can be arranged. Such a choice of height has the advantage that conveniently located below the contact means pedestrian and on the quay wall 9 moving vehicles, without that of the contact means

be hampered or touched.

In Figure 3, a line chain is shown, as for example, as a chain 27 (or as

Line chain 32) is used. It can be clearly seen that this chain of cables is made of movably connected

Chain links 90, 92, 94, etc., which is a bend of the cable chain and the cable 25 guided therein

while limiting the minimum bending radius of the cable. In the left part of Figure 3, the cable 25 has this minimum bending radius, which coincides with the illustrated minimum bending radius of the line chain 27. Through this line chain 27, the cable 25 is on the

Platform 13 guided protected and movement of the first carriage 15 along the longitudinal extent of

Power supply device 1 allows.

In the described power supply device, the electrical contact means (which are also known as

Plug receiving systems can be designated) always horizontally displaceable (movable) and can optionally be carried out additionally vertically displaceable (movable). With this power supply device so the electrical contact means in almost every conceivable position along the quay wall or along the

Ship berth. When the respective contact means is in the desired position, then the plug of the power supply line lowered from the ship into the

appropriate contact means introduced and mechanically

and / or electrically locked with this contact means. After establishing the electrical connection between the plug and electrical contact means then the operation of the shore power supply can be added, the control can be done manually or automatically. Any tidal or vertical movement of the vessel due to loading or unloading is compensated on the ship's side, e.g. from the ship

is decreased or tightened. This can be done for example by a cable reel installed on the ship.

By means of the power supply device 1 ships with a high electric energy demand (high shore power demand) by means of the second contact means / contact system 21 and the third contact means / contact system 50, which are arranged displaceably together, are supplied with electric energy. The second contact means 21 and the third

Contact means 50 are mechanically connected and form a multiple socket. By contrast, ships with low electrical energy requirement (low shore power requirement) can preferably be connected to the first contact means 19 or to the fourth

Contact means 60 are supplied with electrical energy. These contact means 19 and 60 are each as one

Simple socket designed. Because the contact means

arranged horizontally and / or vertically displaceable, the location of the individual ships to be supplied at the ship berth (that is, at the quay wall) plays no role;

Regardless of the location, the ships can

Electric power / shore power are supplied.

If the power supply device 1 is out of operation, then the contact means can be moved into a position, in which they are against the weather and / or against

mechanical damage are protected. Such a protected position may, for example, be located just below the platform 13 or in a housing (not shown in the figures), for example, which is arranged at the end of the platform 13 and in which the contact means can be retracted.

By means of the energy supply device 1, several ships with different electrical energy requirements (i.e., different levels of electrical power consumption) at a berth to a shore power supply can be electrically

be connected. The location of the individual ships on the quay wall does not matter. The operation or

Control of the power supply device can be done manually, fully automatically and / or radio remote controlled.

A power supply device has been described which makes it possible to electrically connect ships lying at ship berths in the harbor with the shore power supply. In this case arranged on a stand contact means are arranged horizontally and / or vertically displaceable, so the most diverse at the ship berth investing ships (possibly also simultaneously) safely and easily to the

Shore power can be connected. The location of the individual ships at the quay wall does not matter.
