BACKGROUND ART In recent years, advances in electrical and electronic equipment related to ships, such as communication, navigation, and wireless, have been noticeable, and work of operators in the wheelhouse has been simplified. On the other hand, the processing by the electric / electronic equipment becomes complicated, and the number of components increases, so that the console tends to be large. Moreover, a plurality of devices such as a console or other devices are usually disposed in the wheelhouse.

However, when arranging a plurality of large consoles or other devices in a wheelhouse of a limited space, there is a fear that the work space of the operator may be limited or the operator may feel pressure.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a steering column structure of a ship that simplifies an operation space of a steering column and improves workability.

In a preferred embodiment of the present invention,

A partition plate for partitioning the steering chamber into an upper chamber and a lower chamber is provided above a floor of a steering chamber formed of a steel plate and subjected to heat radiation processing,

A console in which at least one of an input device and an output device of the arithmetic processing device is mounted is provided in the upper chamber and a cable connecting the arithmetic processing device and the input device, At least one wiring hole through which a cable connecting the arithmetic processing unit and the output device passes is formed in the partition bottom plate.

According to the steering chamber structure of the ship, an input device and an output device are provided in the upper chamber, and an arithmetic processing device connected to the input device and the output device is provided in the lower chamber. That is, the arithmetic processing unit accommodated in the cabinet in the conventional console is installed in the lower room. Therefore, the input device and the output device provided in the upper chamber, where the operator usually stays, are miniaturized as compared with the conventional cabinet type console. That is, it is possible to simplify the equipment installed in the operation space of the wheelhouse (i.e., the upper chamber) without reducing the number of devices provided in the wheelhouse. As a result, the operation space of the operator in the wheelhouse can be expanded and the workability can be improved. Further, it is possible to reduce the floor area of the wheelhouse while securing the operation space of the operator equivalent to the conventional one.

In addition, in the ship's wheelhouse structure, a cable connecting an arithmetic processing unit and an input unit and a cable connecting an arithmetic processing unit and an output unit are inserted into the wiring hole of the partition bottom plate. However, Is unnecessary. Thus, it is possible to reduce labor and cost associated with cable wiring work.

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

As a result, an indoor height sufficient for the operator or the operator to perform the inspection or construction work is secured in the lower room.

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

Thereby, the operator and the operator can visually confirm the state of the arithmetic processing unit provided in the lower chamber through the transmitting portion without moving to the lower chamber.

In the boat room structure of the ship, an inspection port for observing the lower chamber from the upper chamber may be provided on the partition bottom plate.

Thus, the operator and the operator can visually confirm the state of the arithmetic processing unit provided in the lower chamber through the check port without moving to the lower chamber.

An access hatch for accessing a person from the upper chamber to the lower chamber may be provided on the partition bottom plate of the ship's steering column structure.

Thereby, the operator and the operator can move between the upper and lower chambers through the access hatch.

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

Thereby, the lower chamber, in which the arithmetic processing unit for generating heat is disposed, and the upper chamber, which is the operation space of the operator, can be adjusted to the temperature and humidity environment for each purpose.

The ship's wheelhouse structure may include a fire alarm in each of the upper chamber and the lower chamber.

Thus, even if a fire occurs in any of the upper thread and the lower thread, the fire is quickly alarmed.

The steering column structure of the ship may include an automatic diffusion type fire extinguisher in the lower chamber.

This allows rapid initial extinguishment by an automatic diffusion fire extinguisher when a fire occurs in the lower chamber.

A plurality of column members for supporting the partition bottom plate may be erected on the bottom of the wheelhouse in the ship's wheelhouse structure and the arithmetic processing unit may be mounted on the column member.

As described above, since the column member for supporting the partition bottom plate has a function for supporting the processor, the support member for only the processor can be omitted. Therefore, it is possible to secure a work space for an operator or an operator while securing a space for arranging devices such as a wiring space and an arithmetic processing unit in a lower room.

According to the present invention, it is possible to provide a steering column structure of a ship that simplifies the operation space of the steering column and improves workability.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic cross-sectional view of a ship's steering column and its surroundings, showing a ship's ship's room structure according to an embodiment of the present invention; Fig.
2 is a view showing the support structure of the partition bottom plate.
Fig. 3 is a schematic cross-sectional view of a steering chamber of a ship and a periphery thereof, showing a modification of the steering chamber structure of the ship of Fig. 1;

Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a schematic sectional view of a steering chamber 2 of a ship 1 and a periphery thereof showing a steering chamber structure of a ship 1 according to an embodiment of the present invention. 1 shows a steering wheel 2 installed on a ship 1 and a cabin 9 arranged directly below the steering wheel 2. As shown in Fig. 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 bulkhead, or upper and lower decks. The bottom (deck) 20 of the wheelhouse 2 is formed by unfolding and sealing the steel sheet, while heat-radiating is performed by a non-combustible material or a non-combustible seal material. The non-combustible material may be one or more of, for example, glass fiber, ceramic fiber, and rock wool. The floor 20 of the wheelhouse 2 has a fireproof structure along the partition wall and the deck fireproof standard (A60 class partition) with the place adjacent to the control place of the SOLAS Convention.

Although not shown in the drawings, the ceiling of the wheel barrel 2, the partition walls partitioning the wheel barrel 2 and the surrounding cabin are formed by steel plates, and a predetermined heat radiation process is performed. In other words, the wheelhouse 2 is provided with a fireproof structure along the partition wall and deck fire protection standard (A60 class partition) with the place adjacent to the control place of the SOLAS Convention. A60 class divisions are those made of steel or other equivalent materials, (2) suitably reinforced, (3) heat-insulated with non-combustible materials, (4) Means a partition made up of bulkheads or decks complying with the requirements of those specified to prevent the passage of smoke and flames until the end of the standard fire test.

A partition bottom plate 3 is placed above the bottom 20 of the wheel barrel 2 so as to be spaced apart from the bottom 20 by a predetermined distance in the vertical direction. This partition bottom plate 3 divides the steering chamber 2 into two upper and lower spaces of the upper chamber 21 and the lower chamber 22. The upper surface of the bottom 20 of the wheelhouse 2 and the upper surface of the partition bottom plate 3 are parallel. The vertical distance from the upper surface of the bottom 20 of the wheelhouse 2 to the lower surface of the partition bottom plate 3, that is, the height H of the lower chamber 22 is 900 mm or more and less than 2,000 mm. If the height of the lower chamber 22 is 900 mm or more, a sufficient indoor height is secured for the operator or operator to perform the inspection or construction work in the lower chamber 22. However, if the height H of the lower chamber 22 is excessively increased, the height of the wheelhouse 2 becomes excessively high, so that the height H of the lower chamber 22 can be set by the operator or the operator, It is desirable to suppress the height to such an extent as to be possible.

2 is a view showing the supporting structure of the partition bottom plate 3. Fig. 2, the partition bottom plate 3 is mounted on a frame 30 erected on the floor 20 of the wheel barrel 2. As shown in Fig. The frame 30 is constituted by a plurality of pillars 31 provided on the floor 20 of the wheelhouse 2 and a beam 32 connecting the pillars 31 together.

The partition bottom plate 3 may be made of at least one material selected from, for example, a wooden plate, a wooden or resin panel, and a thin steel plate. The partition bottom plate 3 is not limited to the structural member defined by the structural member of the vessel 1 but may have a strength enough to support the load placed on the apparatus or the operator placed on the partition bottom plate 3. [ The partition bottom plate 3 is preferably made of a nonflammable material, but it is not required to be suitable for the requirement for passage of smoke and flames required for class A or class B partitions, and for limiting temperature rise.

The partition bottom plate 3 is provided with an access hatch 38 for an operator or an operator to access from the upper chamber 21 to the lower chamber 22 or vice versa. A plurality of access hatches 38 may be provided in one wheelhouse 2. The access hatch 38 is a door provided with the opening / closing lid 33. The moving manner of the opening / closing lid 33 may be any of a sliding method, an upwardly facing method and a separating method. The lower chamber 22 is provided with a ladder 34 for accessing the access hatch 38.

An arithmetic processing unit 51 and a power supply unit are provided in the lower chamber 22 and an output unit 52 and an input unit 53 are provided in the upper chamber 21 in the steering chamber 2 of the above- And a console 50 on which at least one of them is mounted. The output device 52 has means for outputting information from the arithmetic processing unit 51 and has an information transfer function and / or a situation presentation function. The input device 53 is a means for inputting a command or information to the arithmetic processing unit 51 and has an adjustment function for various situations of the ship 1. [ The device mounted on the console 50 is not limited to the above. For example, a communication device may be mounted.

1 shows a single console 50 included in the navigation and control workstation of the wheelhouse 2 and an arithmetic processing unit 51 corresponding to the single console 50. The plurality of consoles 50 may be provided. In addition to the navigation and maneuvering workstations, the steering room (2) is equipped with a docking workstation, a surveillance and auxiliary navigation workstation, a safety workstation, and a navigation planning workstation, but each workstation has one or more consoles . Each console is equipped with a device or instrument according to the function of the workstation.

The console 50 has a substantially horizontal operation table on which an input device 53 is provided. Further, the output device 52 is disposed at the end of the line of sight of the operator from the console 50 to the operation table.

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. The output device 52 mounted on the console 50 may include a display unit for various instruments such as a gyro compass and a GPS device. For example, various output devices 52 such as an engine monitor, a remote radar, a screen of a ship bridge information unit, a screen of an electronic chart unit, and a near-field radar are mounted on the console of the navigation and control workstation .

The input device 53 mounted on the console 50 may be at least one of a keyboard, a lever, a joystick, a button, a switch, a dial, and a touch panel, for example. For example, the console of a navigation and maneuvering workstation may include an autopilot dial, an engine telegraph, a thruster dial, a joystick lever, a whistle switch, a steering wheel, Various input devices 53 such as an operation unit, an operation panel of an electronic chart unit, a navigation light and a miracle control panel, a thruster, and a steering control panel may be mounted.

The arithmetic processing unit 51 and the output unit 52 are electrically connected (that is, capable of transmitting and receiving signals) by a communication cable. Then, the output signal from the arithmetic processing unit 51 is outputted from the output unit 52. Similarly, the arithmetic processing unit 51 and the input unit 53 are electrically connected by a communication cable. A signal including a command or information input from the input device 53 is input to the arithmetic processing unit 51. An electric supply cable for supplying electricity from an in-line power source (not shown) is connected to the arithmetic processing unit 51, the output unit 52 and the input unit 53. Hereinafter, a communication cable, an electric supply cable, or the like is referred to as a cable type 60.

A wiring hole 55 through which the cable flow 60 passes is formed in the partition bottom plate 3. The wiring hole 55 penetrates through the partition bottom plate 3. The wiring hole 55 may be provided below the leg portion of the console 50 or on the partition bottom plate 3 in the vicinity thereof so as to conceal the wiring hole 55 from the wheelhouse 2 and improve the appearance.

Since the partition bottom plate 3 does not correspond to the partition wall and the deck with respect to the place adjacent to the control place, the conventional penetration process of the penetration portion is unnecessary. The fireproofing of this conventional penetrating portion means, for example, filling a refractory sealing material between a coaming portion forming a penetrating portion and a cable flow 60, and covering the penetrating portion with a heat sink material again.

It is preferable that the arithmetic processing unit 51 is disposed directly below the wiring hole 55 in order to shorten the length of the cable flow 60 and facilitate the wiring. The arithmetic processing unit 51 is mounted on a frame 30 for supporting the partition bottom plate 3. In the present embodiment, a device support 37 is provided so as to extend over a plurality of pillars 31 constituting the frame 30, and an arithmetic processing unit 51 is fixed to the device support 37. As described above, since the support 31 (column member) for supporting the partition bottom plate 3 has a function of supporting the processor 51, the support member for only the processor 51 is omitted I can do it. As a result, it is possible to secure a work space for an operator or an operator while securing a wiring space and a space for arranging apparatuses such as the arithmetic processing unit 51 in the lower chamber 22.

The frame 30 may be provided with a cable hanger 39. The cable hangers 39 are for guiding and supporting the cable streams 60 attached to the lower chamber 22. Here, the cable hanger 39 may be provided on the upper portion of the frame 30. [ As a result, unillustrated ducts, piping, and the like can be laid under the cable flow 60, and interference with the cable flow 60 and the duct, piping, and the like can be avoided. In addition, ducts, pipes, cables 60, an arithmetic processing unit 51, and the like can be arranged in a limited space in the limited lower chamber 22.

As described above, in the structure of the steering column 2 of the ship 1 according to the present embodiment, the arithmetic processing unit 51 housed in the cabinet in the conventional console is installed in the lower chamber 22, An input device 53 and an output device 52 are mounted on the console 50 installed in the upper chamber 21. [ Therefore, the console 50 according to the present embodiment is smaller than the conventional console integrated type console. Such miniaturization of the console 50 can enlarge the operation space of the operator in the wheelhouse 2 and improve the workability of the wheelhouse 2. Further, it is possible to reduce the floor area of the wheel barrel 2 while securing the operation space of the operator equivalent to the conventional one. Further, by adopting the miniaturized console 50, the degree of freedom of each device layout of the wheelhouse 2 is increased as compared with the conventional wheelhouse 2.

In order to further reduce the size of the console 50, the number of alarms installed on 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 alarms. A representative alarm is an alarm for informing the operator of the presence of a fault when a fault occurs.

The individual alarm is installed in the case of the arithmetic processing unit 51 disposed in the lower chamber 22 or in the vicinity thereof and receives a signal from the arithmetic processing unit 51 and other instruments to output an alarm. Here, the typical 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 the arithmetic processing unit 51 detects a defect, it outputs an alarm from both the representative alarm unit and the individual alarm unit. The operator who is found to be defective by the representative alarm recognizes the individual alarms installed in the lower chamber 22 from the upper chamber 21 to know the specific contents of the alarm.

The operator has installed the transmission section 35 on at least a part of the partition bottom plate 3 in order to view various devices including the calculation processor 51 and the alarm installed in the lower chamber 22 from the upper chamber 21 There may be. The transmissive portion 35 of the partition bottom plate 3 is made of a transparent material that is coplanar with the peripheral partition bottom plate 3 and is transparent from the upper chamber 21 to the lower chamber 22. [ As the transparent material, for example, a plate material having strength capable of withstanding the operator's load such as tempered glass or polycarbonate is employed.

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

The operator or the worker does not move to the lower chamber 22 through the transmission portion 35 and / or the inspection port 36 of the partition bottom plate 3 as described above and the situation of various devices installed in the lower chamber 22 Can be seen. If necessary, the operator or the operator can move from the upper chamber 21 to the lower chamber 22 through the access hatch 38 to perform maintenance of various devices.

Smoke detectors 41 and 42 are provided in each of the upper chamber 21 and the lower chamber 22 of the above-described steering wheel 2. Thus, even if a fire occurs in any of the upper chamber 21 and the lower chamber 22, the fire is quickly alerted to the operator or the crew. Further, in the conventional under-floor wiring structure, it is not obligatory to install a fire alarm in the under-floor wiring space.

An automatic diffusion type fire extinguisher (43) is provided in the lower chamber (22) of the wheel barrel (2). The automatic diffusion type fire extinguisher 43 is structured such that it self-ruptures in response to heat to dissipate the powder fire extinguishing agent when the environmental temperature becomes a predetermined temperature or more. As described above, by providing the lower chamber 22 with a fire extinguisher that automatically detects the temperature of the powder fire extinguishing agent due to a fire, the initial fire extinguishing can be performed quickly. In addition, in the conventional under-floor wiring structure, it is not obligatory to install a fire extinguisher in the under-floor wiring space.

An air conditioning apparatus for independently performing air conditioning between the upper chamber 21 and the lower chamber 22 is provided in the wheelhouse 2. [ That is, the indoor units 56 and 57 of the air conditioner are provided in the upper chamber 21 and the lower chamber 22, respectively. One of the outdoor units corresponding to the indoor units 56 and 57 may be provided and an outdoor unit corresponding to each of the indoor units 56 and 57 may be provided. By providing such an air conditioner, it is possible to adjust each of the lower chamber 22 in which various devices including the arithmetic processing unit 51 that generates heat is disposed and the upper chamber 21 as the operation space to an appropriate temperature and humidity environment There is a number.

Although the preferred embodiments of the present invention have been described above, the structure of the steering chamber 2 of the ship 1 can be modified as follows.

For example, in the above-described embodiment, the output device 52 and the input device 53 are integrally mounted on the console 50. However, the output device 52 and the input device 53 may be provided independently of each other. Fig. 3 shows a modified example of the structure of the steering chamber 2 of the ship 1 according to the above embodiment. In the modification shown in Fig. 3, the display, which is an example of the output device 52, and the operation table, which is an example of the input device 53, are independently provided in the upper chamber 21. [ The cables 60 for connecting the output device 52 and the arithmetic processing unit 51 and the cables 60 for connecting the input unit 53 and the arithmetic processing unit 51 are connected to a separate wiring And is introduced into the lower chamber 22 through the hole 55. Note that the detailed description of the modification shown in Fig. 3 is omitted by omitting the same reference numerals as the members similar or similar to those of the embodiment described in Fig.

From the above description, many modifications and other embodiments of the present invention will be apparent to those skilled in the art. Accordingly, the above description is to be construed as illustrative only, and is provided for the purpose of teaching those skilled in the art the best mode of carrying out the invention. The details of the structure and / or function thereof can be substantially changed without departing from the spirit of the present invention.
