Description

Technology Field

[0001] The present invention relates to a firefighting device capable of rapid fire suppression. Background Technology

[0002] Generally, when a fire breaks out, it spreads to the surrounding area and develops into a large-scale fire.

[0003] Therefore, there is a need to rapidly suppress the fire in its initial stages when it occurs.

[0004] In addition, fire doors generally serve the function of preventing the intrusion or spread of smoke and heat in the event of a fire. In particular, fire doors are installed at the entrances of multi-unit dwellings such as apartments or at the doorways of office buildings to prevent the spread of fire.

[0052] The above fire water spraying device (90) is equipped with a sprinkler (91), a fire water supply line (92), and a fire water discharge valve (93), as shown in FIGS. 1 and FIGS. 6.

[0053] The sprinkler (91) is installed on the ceiling (C) of the building. In this embodiment, the sprinkler (91) is a dry sprinkler and is positioned adjacent to the fire door (30). In addition, in this embodiment, multiple sprinklers (91) are provided so that they can be installed at various locations within the building.

[0054] The above fire water supply line (92) supplies fire water to the sprinkler (91). In this embodiment, the fire water supply line (92) is installed in a building and connected to the sprinkler (91), and supplies fire water to the sprinkler (92) when the fire water pump (94) is driven.

In this embodiment, the control unit (110) is electrically connected to the temperature sensor (60), the first and second warning displays (70, 70'), the first and second cooling operation buttons (80, 80'), and the fire detection sensor (100), as shown in FIG. 6. Meanwhile, in this embodiment, the control unit (110) can perform control functions, and its installation location can be varied in various ways.

[0059] FIGS. 7 and 8 are diagrams illustrating the operation of the present invention. With reference to FIGS. 7 and 8, the operation of the present invention is described as follows.

[0060] When the present invention is installed, if a fire occurs in a building, the fire detection sensor (100) detects it and outputs a fire detection signal to the control unit (110).

[0061] Then, the control unit (110) opens the fire water discharge valve (93) to supply fire water to the sprinkler (91). At this time, the control unit (110) drives the fire pump (94) to supply fire water to the fire water supply line (92).

[0062] When firefighting water is supplied to the sprinkler (91) in this manner, the water is sprayed into the passage (P) of the building as shown in Fig. 7, and fire suppression is achieved.

[0063] Meanwhile, the cooling method of the handle mechanism (40) installed on the fire door (30) in the present invention is as follows.

[0064] If a fire occurs inside the building, evacuees will encounter a fire door (30) while evacuating.

[0065] At this time, if the handle mechanism (40) is heated by the heat from the fire, the evacuee may get burned if they carelessly grab the first and second handles (42, 42') in a hurry.

[0066] For example, if a fire occurs in the first passage (P1) as in Fig. 1 and an evacuee must open the fire door (30) and evacuate to the second passage (P2), the evacuee may get burned if they inadvertently grab the first handle (42).

[0067] However, in the present invention, when the temperature of the handle mechanism (40) rises above a reference value, the control unit (110), which receives the abnormal measured temperature value from the temperature sensor (60), displays a request to operate the cooling operation button on the first and second warning displays (70, 70'). For example, the first and second warning displays (70, 70') display a warning message such as, "The handle is hot. Press the front cooling operation button to cool the handle."

[0068] Afterwards, when the evacuee presses the first cooling operation button (80), the control unit (110) opens the coolant discharge valve (54).

[0069] Then, the rapid coolant of the coolant container (51) is sprayed into the latch assembly (41) through the spray nozzle (53) as shown in Fig. 8.

[0070] At this time, the rapid coolant is sprayed into the coolant receiving portion (41b) of the latch assembly (41) to cool the latch assembly (41), and the coolant receiving portion (41b) is equipped with a plurality of cooling fins (41b1) so that the latch assembly (41) is cooled more quickly.

[0071] When the latch assembly (41) is cooled in this way, the first and second handles (42, 42') are cooled together by heat transfer, so that an evacuee can use the first handle (42) to open the fire door (30) and quickly evacuate to a safe place.

[0072] Meanwhile, when the handle mechanism (40) is cooled by the rapid cooling agent spray and the temperature of the handle mechanism (40) returns to a normal state, or when the fire is suppressed and the temperature of the handle mechanism (40) returns to a normal state, the control unit (110) causes the warning message displayed on the first and second warning displays (70, 70') to disappear.

[0074] The present invention, as described above, has the effect of enabling rapid fire suppression within a building by spraying firefighting water through a sprinkler (91) when a fire occurs.

[0075] In addition, the present invention has the effect of allowing a evacuee to safely use the first and second handles (42, 42') without burns and evacuate quickly by rapidly spraying a rapid cooling agent onto the latch assembly (41) when a fire occurs and the fire door (30) and the handle mechanism (40) become hot due to high heat.

[0077] Meanwhile, the title and claims of the present invention are defined as a "firefighting device capable of rapid fire suppression," in the sense that the present invention includes various structures applicable to firefighting structures, such as a structure capable of rapidly suppressing a fire using a sprinkler and a structure capable of safely using a fire door.
