In recent years, advances in electric and electronic related devices such as communication, navigation and radio related to ships have been remarkable, and accordingly, the operation of the operator in the steering room has been simplified. On the one hand, the processing by the electric/electronic related devices is complicated, and since the number of components increases, the console tends to be large. Moreover, a plurality of devices such as a console or other devices are usually arranged in the steering room.

However, when arranging a plurality of large consoles or other devices in the steering room of a limited space, there is a fear that the operator's working space is limited or the operator is under pressure.

The present invention has been made in view of the above circumstances, and its object is to provide a steering wheel structure of a ship that simplifies the operation space of the steering chamber and realizes an improvement in workability.

The steering room structure of the ship according to one aspect of the present invention,

That is, in the conventional console, the computing processing device accommodated in the cabinet is installed in the lower chamber. For this reason, the input device and the output device, which are usually installed in the upper room where the operator stays, are miniaturized compared to a conventional cabinet type console. That is, it is possible to simplify the equipment installed in the operation space (ie, the upper chamber) of the steering chamber without reducing the number of equipment provided in the steering chamber. Thereby, the operator's operation space in the steering room is expanded, and workability can be improved. In addition, the floor area of the steering room can be reduced while securing the operator's operation space equivalent to that of the prior art.

In addition, in the ship's steering room structure, a cable for connecting an arithmetic processing unit and an input device and a cable for connecting an arithmetic processing unit and an output device are inserted through the wiring hole of the partition bottom plate, but a conventional fire-retardant processing is performed in this wiring hole Is unnecessary. Thereby, the trouble and cost associated with wiring of a cable can be reduced.

In the ship's steering chamber structure, the height of the lower chamber may be 900 mm or more and less than 2,000 mm. In addition, the height of the lower chamber is a vertical distance from the upper surface of the bottom of the steering room to the lower surface of the partition bottom plate.

Thereby, sufficient room height is secured in the lower chamber for an operator or operator to perform inspection or construction work.

In the steering room structure of the ship, the partition bottom plate may be provided with a permeable portion for viewing the inside of the lower chamber from the upper chamber.

Thereby, the operator or the operator can visually recognize the state of the arithmetic processing apparatus installed in the lower chamber through the transmission portion without moving to the lower chamber.

In the structure of the steering room of the ship, a check hole for acknowledging the lower chamber from the upper chamber may be provided on the partition bottom plate.

Thereby, the operator or the operator can visually recognize the state of the arithmetic processing apparatus installed in the lower chamber through the inspection port without moving to the lower chamber.

In the ship's steering chamber structure, an access hatch for human access from the upper chamber to the lower chamber may be provided on the partition bottom plate.

Thereby, an operator and an operator can move between an upper chamber and a lower chamber through an access hatch.

The steering chamber structure of the ship may be provided with an air conditioning device that independently performs air conditioning of the upper chamber and the lower chamber.

Thereby, the lower chamber in which the calculation processing apparatus for generating heat is disposed, and the upper chamber serving as the operator's operation space can be adjusted to a temperature and humidity environment for each purpose.

The ship's steering chamber structure may be provided with a fire alarm in each of the upper chamber and the lower chamber.

Thereby, even if a fire occurs in either the upper chamber or the lower chamber, the fire is quickly alerted.

The ship's steering chamber structure may be provided with an automatic diffusion type fire extinguisher in the lower chamber.

By this, when a fire occurs in the lower chamber, rapid initial fire extinguishing is performed by an automatic diffusion type fire extinguisher.

In the steering room structure of the ship, a plurality of pillar members supporting the partition bottom plate may be erected and installed on the bottom of the steering chamber, and the arithmetic processing device may be mounted on the pillar members.

In this way, the pillar member for supporting the partition bottom plate is provided with a function for supporting the computational processing device, so that the supporting member for the computational processing device can be omitted. Therefore, it is possible to secure the working space of the operator or the operator while securing the wiring space and the arrangement space of devices such as a computation processing device in the lower chamber.

Next, embodiments of the present invention will be described with reference to the drawings. 1 is a schematic cross-sectional view of a steering chamber 2 of a vessel 1 and its surroundings, showing a steering chamber structure of a vessel 1 according to an embodiment of the present invention. In Fig. 1, a steering chamber 2 installed in the ship 1 and a cabin 9 disposed immediately below the steering chamber 2 are shown. The cabin 9 may be a cargo room or a machine room.

The ship 1 is provided with a steering chamber 2, which is a space surrounded by a window, a partition, or an upper and lower deck. The bottom (deck) 20 of the steering chamber 2 is formed by spreading and blocking a steel sheet, while performing heat dissipation processing with a non-combustible material or a non-combustible seal material. The non-combustible material may be, for example, one or more of glass fiber, ceramic fiber, and rock wool. The floor 20 of the steering chamber 2 has a fire protection structure that complies with the fire prevention standard (A60 class partition) of the bulkheads and decks between the control place of the SOLAS treaty and the adjacent place.

Although not shown, the ceiling of the steering chamber 2, the partition wall partitioning between the steering chamber 2 and the surrounding cabin, etc. are also formed of steel plates, and a predetermined heat dissipation process is performed. That is, the steering room 2 is provided with a fire protection structure that complies with the fire prevention standard (A60 class partition) of the partition walls and decks between the control place of the SOLAS treaty and the adjacent place.

When the height of the lower chamber 22 is 900 mm or more, a sufficient indoor height is secured in the lower chamber 22 for an operator or operator to perform inspection or construction work. However, if the height H of the lower chamber 22 is excessively high, the height of the steering chamber 2 is excessively high, so the height H of the lower chamber 22 is operated by an operator or operator by bending or sitting down. It is desirable to suppress it to a height as high as possible.

2 is a view showing a supporting structure of the partition bottom plate 3. As shown in Fig. 2, the partition bottom plate 3 is placed on a frame 30 installed on the floor 20 of the steering chamber 2 and installed.

In addition, the input device 53 is a means for inputting commands or information to the arithmetic processing device 51, and has an adjustment function for various situations of the ship 1. In addition, the device mounted on the console 50 is not limited to the above, for example, a communication device may be mounted.

In addition, in FIG. 1, one console 50 included in the navigation and steering workstation of the steering room 2 and an operation processing device 51 corresponding thereto are described, but a plurality of consoles ( 50) may be provided. In the steering room 2, in addition to the voyage and control workstations, an berthing work workstation, a surveillance and auxiliary voyage workstation, a safety workstation, a voyage planning workstation, and the like are installed, but one or more consoles are installed in each workstation. It may be. Each console is equipped with a device or instrument according to the function of the workstation.

The console 50 has an approximately horizontal operating table, and an input device 53 is installed on the operating table. Further, the output device 52 is disposed at the end of the operator's gaze toward the operation table from the console 50.

The output device 52 mounted on the console 50 may be, for example, at least one of a display, a touch panel, an alarm lamp, and an alarm. Further, the output device 52 mounted on the console 50 may include a display unit for various instruments such as a gyro compass or a GPS device.

Various input devices 53, such as an operation panel of an operation unit, an electronic chart unit, a navigation light and a miracle control panel, a thruster and a steering control panel, may be mounted.

The calculation processing device 51 and the output device 52 are electrically connected (ie, capable of transmitting and receiving signals) by a communication cable. Then, the output signal from the operation processing device 51 is output from the output device 52. Similarly, the arithmetic processing device 51 and the input device 53 are electrically connected by a communication cable. Then, a signal including a command or information input from the input device 53 is input to the calculation processing device 51. In addition, an electrical supply cable for supplying electricity from an on-board power supply (not shown) is connected to the calculation processing device 51, the output device 52, and the input device 53. Hereinafter, a communication cable, an electric supply cable, etc. are called cables 60.

A wiring hole 55 through which the cables 60 pass is formed in the partition bottom plate 3. The wiring hole 55 passes through the partition bottom plate 3. In order to conceal the wiring hole 55 from the steering chamber 2 and improve the aesthetics, the wiring hole 55 may be provided on the partition bottom plate 3 below or near the leg portion of the console 50.

Since the partition bottom plate 3 is not applicable to the partition and the deck between the control place and the adjacent place, the fire prevention process of the conventional through portion is unnecessary. The fire prevention process of the conventional penetration part is, for example, filling a refractory sealing material between the coaming and the cables 60 forming the penetration part, and covering the penetration part again with a heat sink material.

The calculation processing device 51 is preferably provided directly below the wiring hole 55 in order to shorten the length of the cables 60 and to facilitate wiring. The arithmetic processing apparatus 51 is attached to the frame 30 for supporting the partition bottom plate 3. In the present embodiment, the device support 37 is provided so as to span the plurality of struts 31 constituting the frame 30, and the arithmetic processing device 51 is fixed to the device support 37. In this way, the support member 31 (column member) for supporting the partition bottom plate 3 is provided with a function for supporting the calculation processing unit 51, thereby omitting the support member for the calculation processing unit 51 only. I can do it. Thereby, while securing the wiring space and the arrangement space of devices, such as the calculation processing apparatus 51, in the lower chamber 22, the working space of an operator or an operator can be secured.

A cable hanger 39 may be provided on the frame 30. The cable hanger 39 is for guiding and supporting the cables 60 attached to the lower chamber 22 at the same time. Here, the cable hanger 39 may be provided on the upper portion of the frame 30. Thereby, ducts, pipes, and the like, not shown, can be laid under the cables 60, and interference of the cables 60 with ducts, pipes, and the like can be avoided. In addition, in the space of the limited lower chamber 22, ducts, piping, cables 60, arithmetic processing devices 51 and the like can be arranged neatly.

As described above, in the structure of the steering chamber 2 of the ship 1 according to the present embodiment, the arithmetic processing apparatus 51 accommodated in the cabinet in the conventional console is installed in the lower chamber 22, The input device 53 and the output device 52 are mounted on the console 50 installed in the upper chamber 21. Therefore, compared to the conventional cabinet-integrated console, the console 50 according to the present embodiment is miniaturized. By miniaturization of the console 50 as described above, the operator's operation space in the steering chamber 2 can be enlarged, and the operability of the steering chamber 2 can be improved. In addition, the floor area of the steering chamber 2 can be reduced while securing the operator's operation space equivalent to that of the prior art. In addition, by adopting the miniaturized console 50, the degree of freedom of layout of each device of the steering chamber 2 is increased compared to the conventional steering chamber 2.

In order to further miniaturize the console 50, the number of alarms installed in the console 50 may be reduced. In this case, a small number of representative alarms are installed in the console 50, and individual alarms are displayed in the lower chamber 22 to display the contents of individual specific alarms. A typical alarm is an alarm for notifying the operator of the presence or absence of a defect when a defect occurs.

The individual alarms are installed in the case of or near the operation processing unit 51 disposed in the lower chamber 22, and receive signals from the operation processing unit 51 or other instruments to output an alarm. Here, the representative alarm may be at least one of an alarm lamp and an alarm speaker, and the individual alarm may be an alarm lamp or the like. When a defect is detected, the arithmetic processing unit 51 outputs an alarm from both a typical alarm and an individual alarm. And the operator who finds out that there is a defect by a representative alarm can recognize the specific contents of the alarm by observing the individual alarms installed in the lower chamber 22 from the upper chamber 21.

In order for the operator to visually recognize various devices including an arithmetic processing unit 51 or an alarm installed in the lower chamber 22 from the upper chamber 21, a transmission portion 35 is installed on at least a portion of the partition bottom plate 3 It may be. The permeable portion 35 of the partition bottom plate 3 is formed of a transparent material that can form the same plane as the surrounding partition bottom plate 3 and can pass through the lower chamber 22 from the upper chamber 21. As the transparent material, a plate material having strength that can withstand the load of the operator, such as tempered glass or polycarbonate, is employed.

In addition, an inspection port 36 for visually recognizing the inside of the lower chamber 22 from the upper chamber 21 may be provided in place of or in addition to the permeable portion 35 in the partition bottom plate 3. The inspection port 36 is an opening for the operator to look into the lower chamber 22 from the upper chamber 21 or insert a hand to perform the work. The inspection port 36 may be provided with a transparent or opaque lid.

As described above, through the permeable portion 35 and/or the inspection port 36 of the partition bottom plate 3, the operator or the operator does not move to the lower chamber 22, and the situation of various devices installed in the lower chamber 22 Can be admitted. In addition, if necessary, the operator or the operator may move from the upper chamber 21 to the lower chamber 22 through the access hatch 38 to perform maintenance of various devices.

Fire alarms 41 and 42 are provided in each of the upper chamber 21 and the lower chamber 22 of the steering chamber 2. Thereby, even if a fire occurs in any one of the upper chamber 21 and the lower chamber 22, the fire is quickly alerted to the operator or the crew. In addition, in the conventional under-floor wiring structure, it is not mandatory to install a fire alarm in the under-floor wiring space.

In the lower chamber 22 of the steering chamber 2, an automatic diffusion type fire extinguisher 43 is provided. The automatic diffusion type fire extinguisher 43 is configured to dissipate a powder fire extinguishing agent by rupturing itself in response to heat when the environment temperature becomes higher than a predetermined temperature. In this way, by providing a fire extinguisher for dissipating the powder extinguishing agent automatically by detecting the temperature rise due to the fire in the lower chamber 22, rapid initial fire extinguishing can be performed. In addition, in the conventional under-floor wiring structure, installation of a fire extinguisher is not mandatory in the under-floor wiring space.

In addition, the steering chamber 2 is provided with an air conditioning device that independently performs air conditioning of the upper chamber 21 and the lower chamber 22. That is, the indoor units 56 and 57 of the air conditioning apparatus are provided in each of the upper chamber 21 and the lower chamber 22. Moreover, one outdoor unit corresponding to these indoor units 56 and 57 may be used, or an outdoor unit may be provided corresponding to each of these indoor units 56 and 57.
