Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric line in a ship, and more particularly to a pit formed under the floor of a steering room to form an electric line.

[0002]

2. Description of the Related Art Ships are equipped with navigational instruments such as radars, and wiring to these electrical devices is required. In this conventional wiring cable, a cable is guided into a steering room where necessary for each device from an electric path formed on the back surface of a deck (hereinafter referred to as a floor deck) below the steering room as shown in FIG. In the figure, 1 is a steering room, 2 is a floor deck of the steering room 1, 3 is a cabin, 4 is a ceiling of the cabin 3, and 5 is a partition wall of the cabin 3.

Reference numeral 6 denotes an electric line formed between the floor deck 2 of the wheelhouse 1 and the ceiling 4 of the cabin 3, and a cable hanger 7 is installed in the electric line 6 and the cable hanger 7 is provided. A cable 9 is held via a cable band 8. The base of the cable 9 is connected to a power source (not shown).

Since each cable 9 is introduced into each device, the floor deck 2 of the wheelhouse 1 is located at an appropriate position for each device.
A wiring hole 10 is formed in the steering wheel 1 and is guided into the steering room 1. In addition, A, B, C, D, E, F, and G indicate respective devices. In this case, it is necessary to partition the steering room 1 and the cabin 3 by the standard A60 of the human life safety regulation (SOLAS), and each wiring hole 10 is provided with a comb containing a filler.

By the way, the innovation and development (function upgrade, version upgrade) of this kind of equipment is remarkable, and each equipment is often newly installed or replaced. At this time, in the above-mentioned conventional electric circuit 6, the ceiling 4 of the cabin 3 is once removed for additional wiring of the cable 9.

Further, wiring holes 10 must be provided in the floor deck 2 at appropriate positions for equipment to be newly installed or replaced, and after the cables 9 have been set through the cables 9, combing with a filler must be performed. Furthermore, the removed ceiling 4 had to be repaired. These operations are large operations and are complicated operations, and in some cases, the strength of the deck 2 may be reduced.

DISCLOSURE OF THE INVENTION The present invention provides an electric circuit in a ship which can very easily carry out the wiring of a cable to a new or replaced device without affecting the disaster prevention standard between the steering room and the cabin. Aim to get.

[0008]

[Means for Solving the Problems] In the electric circuit of a ship, a pit surrounded by a steel plate and sealed to the cabin is formed on the back surface of a floor deck of a steering room, and a cable hanger is provided in the pit. A maintenance hatch was provided on the floor deck at predetermined intervals along the pit position to form an electric circuit. In addition, the maintenance hatch was equipped with a removable lid.

Similarly, it is an electric circuit in a ship, and a pit is formed on the back surface of the floor deck of the steering room, surrounded by a steel plate, opened toward the steering room, and sealed to the cabin. A cover is provided, and openable and closable pit covers are provided at predetermined intervals on the pit cover.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. 1 is a sectional view showing an outline of an electric circuit according to the present invention, FIG. 2 is a plan view of the same, and FIG. 3 is a sectional view of an electric circuit structure. The same parts as those of the conventional type shown in FIG. 4 are designated by the same reference numerals, and detailed description thereof will be omitted.

Reference numeral 11 is a pit formed on the back surface of the floor deck 2 of the wheelhouse 1. As shown in FIG. 2, the pit 11 is provided under a main device in a wide range of the steering room 1, and the inside of the pit 11 serves as an electric path 12. The pit 11 is formed as an airtight groove-like enclosure made by welding a steel plate. For example, a girder, which is a structural member arranged in the longitudinal direction of the hull, can be constructed by welding a floor plate of the pit 11 and a steel plate serving as an end plate in the longitudinal direction.

A cable hanger 13 is fixed in the pit 11, and a cable 9 is attached to the cable hanger 13.
Are secured by the cable band 14. 15
Is a maintenance hatch provided on the floor deck 2 along the pit 11 at predetermined intervals.
The 5 is equipped with a removable lid.

The floor deck 2 may be cut out along the pit 11, the pit 11 may be opened toward the inside of the steering room 1, and the open surface may be covered with a pit cover. In this case, the pit cover is provided with a narrow pit cover which can be easily opened and closed along the pit 11 at a predetermined interval.

In the present invention, the steering room 1 and the cabin 3 are partitioned by the pit 11 which is sealed with respect to the cabin 3. Therefore, as the constituent material of the pit 11, a material that clears the standard A60 described above is used, but the lid of the maintenance hatch 15, the pit cover, and the like may be simple.

The configuration of the present invention is as described above, and when the cable 9 is additionally wired to the electric line 12 when the equipment A, B, C, D, E, F, G is newly installed or replaced, the steering room 1 Open the lid of the maintenance hatch 15 or the openable pit cover from the side, and perform each device A, B, C, D, E,
Wiring to F and G is performed by making a wiring hole 16 in the floor deck 2 or the pit cover at a position suitable for each device. The pit 11 also serves as a reinforcement for the floor deck 2 of the wheelhouse 1.

EFFECTS OF THE INVENTION The present invention forms a pit, which is surrounded by a steel plate and is sealed with respect to a cabin, on the back surface of the floor deck of the wheelhouse, and a cable hanger is provided in the pit. A maintenance hatch is provided at a predetermined interval to form an electric circuit, and the maintenance hatch is equipped with a removable lid.

Further, a pit surrounded by a steel plate, opened to the inside of the steering room, and sealed to the cabin is formed on the back surface of the floor deck of the steering room, and a pit cover is provided on the opening surface. A small width pit cover that can be easily opened and closed is provided at predetermined intervals.

With such a structure, when the electric cable is additionally wired in the electric line, it can be easily performed by opening the maintenance hatch or the openable pit cover from the steering room side. In addition, since the steering room and the cabin are reliably separated by the pits, there is no need for a filling material for the combing for introducing electric wires into each device.
