7 (b) The main body moving driving part 33 rotates the moving rail 31, so that the moving body 31 screwed with the moving rail 31 is moved to the right. Thereafter, the vertical double pipe 351 expands downward by the driving of the vertical driving unit 352, and vertically moves the vertical moving body 34 downward.

8 is a modified example of the mobile fire sensor 20.

When the moving rail 31 is provided with a closed loop chain, the main body moving driving unit 33 is provided with a roller driving motor 332 to rotate the roller on which the sprocket is installed to rotate the closed loop chain, and the moving body installed on the closed loop chain ( 32).

The moving rail 31 made of the closed loop may be provided horizontally or vertically with respect to the user space.

9 is an exemplary view of the vertical moving body (34).

The horizontal rotation part 341 is provided to be rotatable in the horizontal direction with respect to the vertical moving body 34. The horizontal rotation driving part 342 is connected to a horizontal rotation axis to the central axis of the horizontal rotation part 341, and the horizontal driving motor rotates the horizontal rotation axis so that the horizontal rotation part 341 rotates with respect to the horizontal direction. Accordingly, the moving fire detector 20 rotates in the horizontal direction of the vertical moving body 34.

The vertical rotation part 343 is provided to be rotatable in the vertical direction with respect to the vertical moving body 34. The vertical rotation driving unit 344 is connected to the vertical rotation axis on the hinge axis of the vertical moving body 34 and the vertical rotation unit 343, so that the vertical rotation motor rotates the vertical rotation axis so that the vertical rotation unit 343 is rotated with respect to the vertical direction. do. Accordingly, the moving fire detector 20 rotates in the vertical direction of the vertical moving body 34.

Modifications other than the above-described embodiments will be described.

The fire suppression device 1 further includes a communication unit, and can transmit information about the fire to the outside of the central control unit and the fire department. Information about the fire is related to the location of the fire, the type of fire, the extent of the fire, the direction of the fire, the speed of the fire, the video of the fire, the evacuation route, and the like.

One of the suppressing body and the moving rail may be provided with a locking portion and the other with a locking jaw, and if necessary, the suppressing body may not be directed only downward, but may be directed to the side and upward. Accordingly, the fire suppression efficiency of the fire suppression unit may be further improved.

The control unit updates information on the location, height, and type of the items accumulated in the user space, and it is desirable to apply a different fire determination temperature according to the distance between the flame of the fire and the detector. Update the temperature.

The control unit continuously tests the fire detection using the fixed position lighting to determine the presence or absence of a plurality of detectors, compares the detected fire position with the fixed lighting position to determine whether it is within a predetermined range, and determines the information. Inform the user.

Due to the above-described fire suppression device 1, as the mobile fire detector 20 moves, the angle and distance of a location that is identified as a fire at different locations are analyzed to accurately determine the location of the fire and to effectively extinguish the fire. Can be.

The detector driving unit 30 includes at least one moving rail 31, at least one moving main body 32, and a main body moving driving unit 33, so that the moving fire detector 2 is moved around the fire location to determine whether a fire occurs. Can quickly and accurately grasp.

The moving rail 31 is composed of a circulating moving rail 311 disposed with a closed loop, and at least one moving body 32 is periodically moved to periodically rotate the circulating moving rail 311 to detect a fire. By doing so, even if a fire occurs, it can be detected early.

It is possible to quickly and accurately grasp the fire by moving the moving fire detector 20 that was moving the upper area of the user space to the lower area suspected of fire. After the moving fire detector 20 is moved to the lower region suspected of fire, the horizontal and vertical rotation can accurately identify the fire region.
