Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ship electrical wiring apparatus for electrically wiring electrical equipment provided around the upper deck of a ship.

[0002]

2. Description of the Related Art In tankers, liquefied natural gas transport ships, and other general ships, electrical wiring for supplying electric power to and transmitting electric signals to and from electrical equipment provided around the upper deck is provided on the upper deck. It is located in.

An example of a conventional electric wiring device for a ship for electric equipment provided around the upper deck will be described with reference to the longitudinal front view of FIG.
A plurality of mounts c are arranged side by side in the front-rear direction of the hull a, electric wiring d housed in a conduit or the like is installed on the mount c, and is placed in an instrument box e provided on the upper deck b. For electrical equipment (not shown) and deck length warehouse installed on the bow, etc., electrical wiring d installed on the platform c
Therefore, the branch circuit f housed in the conduit tube or the like is appropriately branched and connected.

[0004]

However, in the conventional electric wiring device for a ship shown in FIG. 4, the pedestal c and the electric wiring d interfere with the passage on the upper deck b, and are exposed to wind, rain and waves. Therefore, a special pedestal c having strength is required, and further, it is necessary to provide watertightness by taking measures such as accommodating the electric wiring d in a conduit or the like, and take measures against waves.
There was a problem that maintenance was troublesome.

The present invention solves these conventional problems,
The purpose of the present invention is to provide an electric wiring device for a ship that does not obstruct the passage on the upper deck, does not need to be provided with a stand for electric wiring, does not require special measures against waves, and is easy to maintain. is there.

[0006]

An electric wiring device for a ship according to the present invention is characterized in that a cable duct extending in the longitudinal direction of a hull is attached to a lower surface of an upper deck, and the electric wiring is provided in the cable duct. The upper deck directly above the cable duct can be provided with a hatch that can be opened and closed from above the upper deck.

[0007]

[Function] Since the cable duct for accommodating the electric wiring is attached to the lower surface of the upper deck and the electric wiring is provided in the cable duct, it is not necessary to provide a mount on the upper deck, and the electric wiring is not exposed on the upper deck. There is no obstruction to the passage of the upper deck, no special wave countermeasures are required for the electrical wiring, and maintenance work is reduced.

By providing a hatch on the upper deck just above the duct, which can be opened and closed from the upper deck, the installation and maintenance of the electric wiring can be performed using the hatch, so that the installation and maintenance of the electric wiring can be easily performed. become.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, a plurality of cable ducts 3 and 4 are attached to the lower surface of the upper deck 2 of the hull 1 so as to extend in the front-rear direction of the hull 1, and the cable duct 3 is attached. Electrical wirings 5 and 6 are housed and wired in the interiors of the wirings 4 and 4, respectively.

One electrical wiring 5 is classified as a wiring for transmitting electric signals for an intrinsically safe circuit, and the other electrical wiring 6 is classified as a wiring for transmitting electric power such as wiring for a general circuit. In order to protect the electric wiring 5 and 6 against the shaking of the expansion box 7 in place (buffer tray)
Is installed.

On the upper deck 2 directly above the cable ducts 3 and 4, hatches 8 that can be opened and closed from the upper deck 2 are provided at appropriate distances, and by opening the hatch 8, the inside of the cable ducts 3 and 4 from the upper deck 2 is opened. You can enter and leave.

For an electric device (not shown) arranged in an instrument box 9 provided on the upper deck 2, a branch circuit 10 housed in a conduit or the like is appropriately connected from the electric wiring 5. For electrical equipment such as an illumination lamp 12 (see FIG. 1) that is branched and connected and is mounted on the lamp post 11, a branch that is branched from the electrical wiring 6 and is housed in a conduit tube or the like. The circuit 13 is connected.

In the figure, reference numeral 14 is living equipment, 15 is a wheelhouse, and 16
Is an engine room, 17 is a main switchboard provided beside the engine room 16, 18 is a cable trunk space vertically formed in the living facility 14, 19 is a horizontal cableway, and 20 is a deck length warehouse provided at the bow. Show.

The electric wirings 5 and 6 arranged in the cable ducts 3 and 4 have one end extending to the deck length warehouse 20 and the other end passing through the cable trunk space 18 to the steering room 15 or a horizontal cable. It extends through the way 19 to the main switch board 17 in the engine room 16.

According to the above embodiment, in order to send and receive electricity to the electrical equipment provided in the instrument box 9, lamp post 11, deck length warehouse 20 and the like arranged around the upper deck 2, Since the electric wirings 5 and 6 are provided in the cable ducts 3 and 4 provided on the lower surface of the upper deck 2, it is not necessary to provide the electric wiring and the pedestal for the electric wiring on the upper deck 2, thus There is an advantage that passage over the upper deck 2 is facilitated and no countermeasures against waves of electric wiring are required.

Further, since the hatch 8 which can be opened and closed from the upper deck 2 is provided on the upper deck 2 directly above the cable ducts 3, 4, the electric wiring 5, 5 is utilized from the upper deck 2.
6 can be installed and maintained easily.

[0018]

According to the present invention, since there is no electric wiring on the upper deck of a ship, it is not necessary to provide a cradle for electric wiring on the upper deck, and the electric wiring of the upper deck hinders the passage of the upper deck. Therefore, there is no need to take measures against the waves of the electric wiring, and there is an effect that maintenance is not troublesome.

Furthermore, on the upper deck directly above the cable duct,
Since the hatch that can be opened and closed from the upper deck is provided, there is an effect that installation and maintenance of electric wiring can be easily performed by using the hatch from the upper deck.
