Description

Description: TECHNICAL FIELD The present invention relates to a fire monitoring device for ship construction, and in particular,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction fire monitoring device for a ship that detects a fire that occurs on the back side of the construction and issues an alarm when performing a fire construction on a ship.

[Prior Art] Generally, in the construction or repair / remodeling work of a ship, fire work such as welding or fusing work is performed. At the time of the fire work, combustible materials on the back surface side of the floor or wall where the work is performed burn and a fire occurs, which may cause a great disaster.

In order to prevent this, conventionally, an observer has been arranged on the back side of a floor or a wall or the like where a fire work is performed to prevent a fire from occurring.

[Problems to be Solved by the Invention] However, in the above-described method, when the number of construction sites increases, a large number of observers must be arranged according to the construction sites, and the monitoring area is narrow and the monitoring area is narrow. Monitoring may be overlooked because a person cannot enter, causing a fire. Further, there is a problem that the number of workers is increased due to the necessity of a large number of supervisors, which increases costs.

The present invention has been made in order to solve the above-described problems, and an object of the present invention is to prevent a fire from occurring without placing a supervisor on the back side of the work, thereby reducing costs. An object of the present invention is to provide a fire monitoring device for ship construction which can be planned.

[Means for lashing the object] In order to achieve the above object, the present invention relates to a device for monitoring a fire occurring on the back side of a floor or a wall, etc., on which a hot work is performed in a ship. A fire detector comprising a smoke sensor and a flame sensor provided in each room located on the back side of a floor or a wall, and a monitoring unit connected to the fire detector and centrally monitoring these fire detectors; An alarm that is provided in the monitoring unit and that issues an alarm when a fire is detected by the fire detector.

[Action] When performing hot work such as fusing or welding on board a fire detector is installed in each room located on the back side of the floor or wall in the room where the work is performed, and general work while working on the ship The monitoring unit may be installed at a place where the user can confirm, and the monitoring unit and each fire alarm may be connected.

During the fire work, a fire that occurs on the back side is detected by a smoke sensor or a flame sensor, and is detected by a monitoring unit via a fire detector, and at the same time, an alarm is issued from an alarm device. Workers in the vicinity who have confirmed the alarm immediately engage in fire fighting, so that the fire can be extinguished at an early stage.

In this way, a fire can be detected at an early stage without specially placing a supervisor for fire detection, thereby preventing fires from occurring and reducing the number of workers. Cost can be reduced.

Embodiment An embodiment of the present invention will be described with reference to the accompanying drawings.

1 to 3 show an embodiment of a fire monitoring device for construction of a ship according to the present invention.

FIG. 1 shows a plan view of the interior of the ship, and the interior of the ship is constituted by arranging a number of cabins 2 around a corridor 17 around an engine room 16.

A portable fire detector 1 is arranged in each of the rooms 2 on the back side where the fire work is performed. That is, the fire detector 1 is installed in each cabin 2, whereby the fire detection area 1 is installed in the cabin 2 on the back side of the wall 18 such as a partition that divides the cabin 2 where fire work is performed. Further, in addition to the cabin 2, the fire detector 1 may be installed under the floor or above the ceiling, which is a room on the back side of the cabin 2 where the fire work is performed.

These fire detectors 1 include a smoke sensor 3 for detecting a fire.
And a flame sensor 4.

A monitoring unit 5 for centrally monitoring the fire alarms 1 is provided at a required place on the ship, for example, in a corridor 17, and this monitoring unit 5 and each fire detector 1 are connected via a cable 6. I have.

As shown in the block diagram of FIG. 2 and the electric circuit diagram of FIG. 3, the monitoring unit 5 includes a logic control unit 7 that processes signals from the smoke sensor 3 and the flame sensor 4 of the fire detector 1, The control unit 7 is connected to a power supply unit 8 for supplying power thereto. The logic control unit 7 is connected to a display unit 9 for displaying a fire scene, and is provided with an electronic buzzer 11 and a rotating light 12 as an alarm device 10 for issuing an alarm simultaneously with detection of a fire. The rotating lamp 12 is lit through a timer unit 13 only for a certain period of time after the fire is detected.

In the figure, reference numeral 14 denotes a fire detector for detecting a fire occurring in the vicinity of the monitoring unit 5, and reference numeral 15 denotes a logic control unit 7 when power from the power supply unit 8 cannot be obtained due to a power failure or the like. This is a battery for supplying power to the battery.

 Next, the operation of the above embodiment will be described.

First, as shown in FIG. 1, when performing a fire work such as fusing or welding inside a ship, the fire detector 1 is installed in the cabin 2 below the floor or behind the partition wall 18 in the room where the work is performed. At the same time, the monitoring unit 5 is installed at a place where a general worker working on the ship can check.
And the monitoring unit 5 may be connected by a cable 6.

During the construction work, the fire that occurs on the back side is detected by the smoke sensor 3 or the flame sensor 4, detected by the logic control unit 7 of the monitoring unit 5 via the fire detector 1, and simultaneously by the alarm device 10. An alarm is issued. Workers in the vicinity who have confirmed the alarm immediately engage in fire fighting, so that the fire can be extinguished at an early stage.

In this way, a fire can be detected at an early stage without specially arranging a supervisor for fire detection, thereby preventing the occurrence of a fire and reducing the number of workers. Cost can be reduced.

Further, since the fire detector 1 is portable, it can be appropriately selected and arranged easily even in a desired place or a narrow place.

Further, since the battery 15 is provided in the monitoring unit 5, even if a power outage or a ship under construction is moored offshore and power cannot be obtained from an external power supply, it is possible to monitor the occurrence of a fire.

In the above embodiment, a fire alarm is issued only to the onboard worker. However, the monitoring unit 5 is connected to an alarm provided at a guardhouse or a fire station using a telephone line or the like. If this is done, it is possible to detect a fire that occurs when there are few workers at night or after the construction is completed.

[Effects of the Invention] According to the present invention, a fire detector is provided in the room on the back side of the floor or wall where fire work is performed, and monitoring is performed by the monitoring unit, so that it is possible to prevent fire from occurring. In addition, since it is possible to monitor the fire without specially arranging a supervisor, it is possible to reduce the number of workers and to achieve excellent effects such as reduction in construction cost.
