Abstract
Description
Technology Field
[0001] The present invention relates to a firefighting safety evacuation guidance device. Background Technology
[0002] Generally, since suffocation from smoke is the most common cause of fire in buildings, people can evacuate quickly by following evacuation guidance lights; recently, technology combining these evacuation guidance lights with fire hydrants has been developed and is being implemented.
[0003] The above fire hydrant is a facility installed to suppress a fire when a fire occurs in a building. An example of a conventional indoor fire hydrant is disclosed in Korean Registered Patent Publication No. 10-2206116, which comprises: a main body having an angle valve and a nozzle inside a space that is opened and closed by a door, and having an externally exposed sound device and an indicator light; a transmitter mounted in an exposed state on the main body and triggering the operation of the sound device and indicator light by pressing; a detection means for detecting an operation mode through a mode switch mounted on the main body; and a controller for controlling the operation of the main body and the transmitter in response to a signal from the detection means.
[0004] These conventional indoor fire hydrants increased operational flexibility by selectively controlling key functions, such as alarm transmitters, in response to various situations, thereby enhancing not only fire alarming and suppression but also maintenance efficiency.
[0005] Meanwhile, in the case of conventional fire hydrants, if you want to unwind the hose in a direction other than forward (left or right), the reel member and the fire hose are bent at a 90-degree angle, so it does not unwind easily; therefore, you have to unwind the hose completely and then carry it to the point of ignition, but there was a very serious problem that it could get tangled if you went in that unwinded state.
[0006] In particular, in the case of buried indoor fire hydrants, the structure prevents the door from opening completely, which causes interference between the door and the fire hose, resulting in damage to the fire hose or the door. Prior art literature

[0041] The present invention has the effect of inducing rapid evacuation because, by separating the first door from the first enclosure and then standing the separated first door upright like a signboard using a door support, the evacuation direction is displayed through an evacuation route guidance unit installed on the first door, thereby allowing the evacuation direction to be intuitively confirmed in an emergency situation.
[0042] In addition, when a fire approaches the vicinity of the fire hydrant box, the user can directly extinguish the fire using the firefighting water discharged from the spray gun while holding it, or indirectly extinguish the fire using the firefighting water discharged from the spray gun while the user mounts the spray gun on the mounting hole and stand, thereby contributing to rapid fire suppression.
[0043] In addition, since the first door is separated from the first enclosure and the first fire hose is withdrawn with the first door removed, interference with the first door can be fundamentally prevented, allowing the first fire hose to be withdrawn quickly in any direction and the fire to be extinguished.
[0044] In addition, since the bobbin mounting tube rotates around a vertical axis and the first hose reel is installed on the bobbin mounting tube and rotates around a horizontal axis, when the first fire hose is pulled out, its position naturally changes in the direction of the pull-out, facilitating easy unwinding. This allows the user to operate the device without considering the pull-out direction of the first fire hose, and fundamentally resolves the problem of the first hose reel getting caught during the pull-out process, thereby significantly improving user convenience.

[0047] The following is a detailed explanation based on the attached drawings.
[0049] FIG. 1 is a perspective view of a fire safety evacuation guidance device according to the present invention with the first door closed, FIG. 2 is a perspective view of a fire safety evacuation guidance device according to the present invention with the first and second doors open, FIG. 3 is a front view of a fire safety evacuation guidance device according to the present invention with the first and second doors open, FIG. 4 is a partial side cross-sectional view of a fire safety evacuation guidance device according to the present invention, FIG. 5 is a plan cross-sectional view showing part “A” of FIG. 4 separately, and FIG. 6 is an exploded perspective view showing the first door of a fire safety evacuation guidance device according to the present invention separately.
[0051] Referring to FIGS. 1 to 4, the firefighting safety evacuation guidance device according to the present invention comprises a fire hydrant box (10), a transfer unit (20), a first hose reel (30), a second hose reel (40), an angle valve (50), a first fire hose (60), a second fire hose (70), a pressure regulating pressure reducing valve (80), a transmitter push switch (90), a control unit (100), a speaker (110), a warning light unit (120), and an evacuation route guidance unit (130). According to this, safe evacuation can be induced in that the first door (12) is separated from the first enclosure (11), and the separated first door (12) is set up like a signboard using a door support (13), and the evacuation direction can be visually indicated to the evacuee through the evacuation route guidance unit (130). When a fire approaches the vicinity of the fire hydrant box (10), the user can directly extinguish the fire using the fire extinguishing water discharged from the spray gun (71) while holding the spray gun (71), or indirectly extinguish the fire using the fire extinguishing water discharged from the spray gun (71) while the user is mounted on the mounting hole (12b) and the mounting stand (15), thereby contributing to rapid fire suppression. Additionally, since the first door (12) is separated from the first box (11) and the first fire hose (60) is pulled out with the first door (12) removed, interference with the first door (12) can be fundamentally prevented, allowing the first fire hose (60) to be pulled out quickly in any direction and the fire to be suppressed. This is a technical feature.
[0053] Referring to FIGS. 1 to 6, the fire hydrant box (10) is composed of a first housing (11), a first door (12), a door support (13), a spray gun support (14), a stand (15), and a viewing window (16).
[0054] The first housing (11) is a metal member in the shape of a rectangular parallepiped with an opening in the front, and in the case of this embodiment, it is embedded in a wall (W) so that the front is exposed to the outside, and a round bar (11a) is installed vertically on one side of the open front.
[0055] The first door (12) is installed in the first enclosure (11) in a hinged manner and serves to open and close the front opening of the first enclosure (11).
[0056] A connector (12a) is installed on the upper, lower, and middle portions of the side of the first door (12), and the connector (12a) is detachably connected to a round bar (11a) and rotates around the round bar (11a).
[0057] Additionally, a circular mounting hole (12b) communicating with the interior of the first housing (11) is formed on the front of the first door (12), pin holes (12c) are integrally formed on both sides of the upper part, and a handle (12d) is formed on the front so that the first door (12) can be easily opened and closed.
[0058] Regarding the separation and connection of the first housing (11) and the first door (12), as shown in FIG. 5, when the first door (12) is pushed strongly backward while the first housing (11) and the first door (12) are open and perpendicular to each other, the connection between the rod (11a) and the connector (12a) is released and they are separated from each other. When the first door (12) separated in this way is moved sequentially to the right and forward, the first door (12) is completely separated from the first housing (11), and the connection of the first housing (11) and the first door (12) can be carried out in the reverse order of the method described above.
[0059] The above door support (13) is installed on the first door (12) and serves to support the first door (12) so that it does not fall over when the first door (12), separated from the first enclosure (11), is set up like a signboard. In the case of this embodiment, it is installed so that it can be folded or unfolded by means of a pin (P) that is positioned on the rear of the first door (12) and connected to pass through the pin hole (12c).
[0060] In addition, the upper part of the door support (13) is formed to be tapered at a predetermined angle so as to limit the unfolding angle.
[0061] In addition, height adjustment grooves (13a) are formed at regular intervals along the vertical length direction on one side of the door support (13).
[0062] The above-mentioned spray gun support (14) is a rectangular block, and at one end, a fitting projection (14a) is integrally formed to be detachably coupled to a height adjustment groove (13a).
[0063] The above-mentioned spray gun support (14) is detachably coupled to the height adjustment groove (13a) via the insertion projection (14a) to support the spray gun (71) and to adjust the mounting angle of the spray gun (71).
[0064] For example, when the spray gun support (14) is attached to the middle height adjustment groove (13a), the spray gun (71) is positioned horizontally, when the spray gun support (14) is attached to the upper height adjustment groove (13a), the discharge port of the spray gun (71) is positioned at a downward slope, and when the spray gun support (14) is attached to the lower height adjustment groove (13a), the discharge port of the spray gun (71) is positioned at an upward slope, so it is very useful to be able to spray firefighting water at various angles depending on the location of the fire (ceiling, wall, floor).
[0065] The above-mentioned mounting bracket (15) is a Y-shaped member and, in the case of this embodiment, is installed on the upper surface of the spray gun support (14) and serves to support the spray gun (71) so that it can be mounted together with the mounting hole (12b).
[0066] The above-mentioned viewing window (16) is a transparent synthetic resin plate and, in the case of this embodiment, is rotatably installed on the front of the first door (12) to open and close the mounting hole (12b) (see FIG. 11).
[0067] As in the present embodiment, if the first door (12) is manufactured in a structure that allows it to be separated from the first enclosure (11), interference with the first door (12) during the process of drawing out the first fire hose (60) can be fundamentally prevented, so the first fire hose (60) can be drawn out quickly in any direction and then the fire can be extinguished.
[0068] In addition, the separated first door (12) can be set up like a signboard using a door support (13) and visually inform the evacuee of the evacuation direction through the evacuation route guidance unit (130), thereby having the effect of inducing safe evacuation.
[0069] Finally, when the spray gun support (14) is attached to the middle height adjustment groove (13a), the spray gun (71) is positioned horizontally, and when the spray gun support (14) is attached to the upper height adjustment groove (13a), the discharge port of the spray gun (71) is positioned at a downward slope, and when the spray gun support (14) is attached to the lower height adjustment groove (13a), the discharge port of the spray gun (71) is positioned at an upward slope, so it is very useful to be able to spray firefighting water at various angles depending on the location of the fire (ceiling, wall, floor).
[0071] Referring to FIGS. 2 to 4, the transfer unit (20) is composed of a guide part (21), a rail part (22), a sub-box (23), a stopper (24), and a bobbin mounting tube (25). In the case of the present embodiment, it is installed inside the fire hydrant box (10) and serves to allow the first thruster (30) to rotate around a vertical axis while being withdrawn from the fire hydrant box (10) or stored in the fire hydrant box (10).
[0072] The above guide section (21) and rail section (22) are known LM guides, the guide section (21) is installed parallel to the inner bottom surface of the fire hydrant box (10), and the rail section (22) is installed to slide along the guide section (21).
[0073] The above sub-box (23) is composed of a second box (23a) and a second door (23b). In the case of the present embodiment, it is installed on the upper surface of the rail section (22) and moves together with the rail section (22) when it moves, so that it is withdrawn from the fire hydrant box (10) to the outside or stored in the fire hydrant box (10).
[0074] Inside this sub-box (23), a second hose reel (40) with a second fire hose (70) wound around it is stored.
[0075] The above stopper (24) is installed on the lower surface of the sub-box (23) so as to be positioned between the rail sections (22) and serves to limit excessive withdrawal of the sub-box (23).
[0076] For example, when the stopper (24) gets caught on the inner lower part of the first housing (11) during the process of the sub-box (23) being withdrawn via the rail part (22), the withdrawal of the sub-box (23) is restricted.
[0077] The above bobbin mounting tube (25) is a pipe bent in multiple stages, and in the case of this embodiment, the lower end is installed so as to be rotatable around a vertical axis by penetrating the upper surface of the sub-box (23).
[0078] For example, the bobbin mounting tube (25) is positioned to be erected in the sub-box (23), and its lower end is installed in the sub-box (23) via a bearing so as to rotate clockwise or counterclockwise around a vertical axis.
[0079] At the upper end of the bobbin mounting tube (25), the first shaft tube (31) of the first thruster (30) is installed via the first anti-twisting means (TP1) and rotates clockwise or counterclockwise around the horizontal axis, and at the lower end of the bobbin mounting tube (25), the second shaft tube (41) of the second thruster (40) is installed via the third anti-twisting means (TP3) and rotates clockwise or counterclockwise around the vertical axis.
[0080] Additionally, as the interior of the bobbin mounting tube (25) is structured to be mutually connected with the interiors of the first shaft tube (31) and the second shaft tube (41), firefighting water introduced through the first shaft tube (31) is supplied to the second shaft tube (41) via the bobbin mounting tube (25).
[0081] According to the present embodiment, since the bobbin mounting tube (25) rotates around a vertical axis and the first hose reel (30) is installed on the bobbin mounting tube (25) and rotates around a horizontal axis, when the first fire hose (60) is pulled out, the position of the first fire hose (60) naturally changes in the direction of the pull-out and helps to unwind easily. This allows the user to use the first fire hose (60) without considering the pull-out direction, and also fundamentally resolves the problem of the first hose reel (30) getting caught during the pull-out process of the first fire hose (60), thereby greatly improving convenience of use.
[0083] Referring to FIGS. 2 to 4, the first hose reel (30) is composed of a first shaft tube (31), a connecting tube (32), and a first bobbin (33). In the case of the present embodiment, it is installed at the upper end of the bobbin mounting tube (25) so as to be rotatable around a horizontal axis and serves to wind or unwind the first fire hose (60).
[0084] The first shaft tube (31) is a pipe with a through hole in the interior, and one end is rotatably installed via the upper end of the bobbin mounting tube (25) and the first anti-twist means (TP1), and the first shaft tube (31) thus installed rotates around a horizontal axis.
[0085] A first branch pipe (31a) is integrally formed on the outer surface of the first shaft pipe (31) and is in communication with the interior of the first shaft pipe (31), and one end of the first fire hose (60) is detachably connected to the first branch pipe (31a).
[0086] The above connecting pipe (32) is an elbow pipe, and one end is rotatably installed through the other end of the first shaft pipe (31) and the second anti-twist means (TP2), and the connecting pipe (32) thus installed rotates around a horizontal axis.
[0087] A connecting hose (51) of an angle valve (50) is detachably connected to the other end of this connecting pipe (32).
[0088] The first bobbin (33) is integrally formed on the outer surface of the first shaft tube (31) so as to be positioned between the first and second anti-twist means (TP1, TP2), and rotates together with the first shaft tube (31) when it rotates, and serves to wind or unwind the first fire hose (60).
[0090] Referring to FIGS. 2 to 4, the second hose reel (40) is composed of a second shaft tube (41) and a second bobbin (42). In the case of this embodiment, it is installed in the sub-box (23) so as to be rotatable around a vertical axis and serves to wind or unwind the second fire hose (70).
[0091] The second shaft tube (41) is a pipe with a through hole in the interior, and one end (upper end) is rotatably installed via the lower end of the bobbin mounting tube (25) and the third anti-twist means (TP3), and the other end (lower end) is rotatably installed via a bearing in the sub-box (23), and the second shaft tube (41) installed in this way rotates clockwise or counterclockwise around a vertical axis.
[0092] A second branch pipe (41a) is integrally formed on the outer surface of the second shaft pipe (41) and communicates with the interior of the second shaft pipe (41), and one end of the second fire hose (70) is detachably connected to the second branch pipe (41a).
[0093] The second bobbin (42) is integrally formed on the outer surface of the second shaft tube (41) and rotates together with the second shaft tube (41) when the second shaft tube (41) rotates, and serves to wind or unwind the second fire hose (70).
[0095] Referring to FIGS. 3 and 4, the angle valve (50) is installed in the fire hydrant box (10) and serves to control the flow of fire extinguishing water.
[0096] This angle valve (50) is equipped with a connecting hose (51) that is interconnected with a connecting pipe (32). When the angle valve (50) is opened, firefighting water is supplied sequentially through the connecting hose (51) → connecting pipe (32) → first shaft pipe (31) → bobbin mounting pipe (25) → second shaft pipe (41). During this process, the firefighting water supplied to the first shaft pipe (31) is supplied to the first fire hose (60) through the first branch pipe (31a), and the firefighting water supplied to the second shaft pipe (41) is supplied to the second fire hose (70) through the second branch pipe (41a).
[0098] Referring to FIGS. 2 to 4, the first fire hose (60) is installed to be wound and unwound on the first hose reel (30) and serves to receive firefighting water and spray firefighting water.
[0099] One end of the first fire hose (60) is provided with a nozzle (61), and the other end is detachably connected to the first branch pipe (31a) to receive firefighting water through the first branch pipe (31a) and spray firefighting water through the nozzle (61).
[0100] For example, the first fire hose (60) is wound on the first hose reel (30), and when the user pulls the first fire hose (60) as needed, it is unwound from the first hose reel (30).
[0102] Referring to FIGS. 2 to 4, the second fire hose (70) is installed to be wound and unwound on the second hose reel (30) and serves to receive firefighting water and spray firefighting water.
[0103] The above-mentioned second fire hose (70) is provided with a spray gun (71) at one end and the other end is detachably connected to a second branch pipe (41a) to receive depressurized firefighting water through the second branch pipe (41a) and spray firefighting water through the spray gun (71).
[0104] For example, the second fire hose (70) is wound on the second hose reel (40), and when the user pulls the second fire hose (70) as needed, it is unwound from the second hose reel (40).
[0105] In addition, the spray gun (71) is provided with a catch (71a) to prevent the spray gun (71) from being unintentionally detached from the stand (15).
[0107] Meanwhile, the second fire hose (70) is used as a temporary measure when a fire approaches the fire hydrant box (10) or when a fire around the fire hydrant box (10) needs to be urgently suppressed in the absence of the first fire hose (60).
[0108] Therefore, since the second fire hose (70) does not need to be supplied with high-pressure firefighting water like the first fire hose (60), it does not need to be made of a material capable of withstanding high pressure. However, if high-pressure firefighting water flows into the second fire hose (70), there is a risk that the second fire hose (70) will burst because it cannot withstand the pressure.
[0109] Accordingly, in this embodiment, such a problem was resolved by applying a pressure regulating pressure reducing valve (80).
[0110] Referring to FIGS. 2 to 4, the pressure regulating pressure reducing valve (80) is a known pressure reducing valve, and in the case of this embodiment, it is installed in the bobbin mounting pipe (25) and serves to reduce the pressure of firefighting water flowing into the bobbin mounting pipe (25) and discharge it to the second shaft pipe (41).
[0111] As described above, the firefighting water reduced in pressure by the pressure regulating pressure reducing valve (80) is supplied to the second fire hose (70) through the second shaft pipe (41), thereby easily solving the problem of damage to the second fire hose (70) caused by high pressure.
[0113] Referring to FIGS. 1 to 3, the transmitter push switch (90), control unit (100), speaker (110), and warning light unit (120) are described as follows.
[0114] The above-mentioned transmitter push switch (90) is installed on the front of the fire hydrant box (10) so that a discoverer can notify in case of fire, and serves to output a fire signal to the control unit (100).
[0115] The above control unit (100) receives a fire signal from the transmitter push switch (90) and controls the operation of the speaker (110) and the warning light unit (120), respectively. For example, when a fire signal is input to the control unit (100) from the transmitter push switch (90), the control unit (100) transmits the fire signal to a control room where a manager is stationed, controls the operation of the speaker (110) so that a fire warning sound is output from the speaker (110), and controls the operation of the warning light unit (120) so that a red light is turned on (or flashes) from the warning light unit (120).
[0116] The above speaker (110) is installed on the front of the fire hydrant box (10) and is operated by the control unit (100) to output a fire warning sound such as a voice (e.g., fire!) or a siren.
[0117] The above warning light unit (120) is installed on the front of the fire hydrant box (10) and is operated by the control unit (100) to light up (or flash) a red light.
[0119] Referring to FIGS. 1, 2, 4, and 6, the evacuation route guidance unit (130) is composed of a power supply unit (131), an operation switch (132), a direction selection switch (133), and a display (134). In the case of the present embodiment, it is installed on the first door (12) and serves to visually indicate the evacuation direction.
[0120] The above power supply unit (131) is a replaceable known battery and, in the case of this embodiment, is installed on the rear of the first door (12) to supply power.
[0121] The above-mentioned operation switch (132) is a type of ON / OFF switch and, in the case of this embodiment, is installed on the rear of the first door (12) to control the power supply to the display (134).
[0122] The above direction selection switch (133) is installed on the rear of the first door (12) and serves to selectively switch the evacuation direction visually displayed on the display (134).
[0123] The above display (134) is installed on the front of the first door (12) and serves to visually indicate the evacuation direction.
[0125] For example, when the user presses the operation switch (132) to turn it ON, power from the power supply unit (131) is supplied to the display (134) through the operation switch (132), and the display (134) receives power and visually displays an evacuation direction arrow.
[0126] At this time, if the user wants to change the evacuation direction displayed on the display (134) to another direction, the user presses the direction selection switch (133), and the evacuation direction arrow displayed on the display (134) is changed to the opposite direction.
[0128] According to the present embodiment, by displaying the evacuation direction through the evacuation route guide unit (130) installed on the first door (12) as described above, the evacuation direction can be intuitively checked in an emergency situation, thereby having the effect of inducing rapid evacuation.
[0130] FIGS. 7 to 13 are drawings for explaining the effects of a firefighting safety evacuation guidance device according to the present invention, and with reference thereto, the explanation is as follows.
[0131] When a fire occurs in a building and a fire discoverer presses the transmitter push switch (90), a fire signal is output from the transmitter push switch (90) and input to the control unit (100). The control unit (100) receives the fire signal and transmits it to a control room where an administrator is stationed, and also controls the operation of the speaker (110) and the warning light unit (120).
[0132] The above speaker (110) is controlled by the control unit (100) to output a fire warning sound such as a voice (e.g., fire!) or a siren, and the warning light unit (120) is controlled by the control unit (100) to turn on (or flash) a red light.
[0133] Meanwhile, when two facility managers arrive at the fire hydrant box (10) near the fire scene to provide fire suppression and evacuation guidance, as shown in FIGS. 7 to 10, one person separates the first door (12) from the first box (11), and when the first door (12) is separated, the other person uses a transfer unit (20) to pull out the first hose reel (30) on which the first fire hose (60) is wound out of the fire hydrant box (10).
[0134] As described above, when the first reel (30) is pulled out, the facility manager moves the first fire hose (60) to the fire scene while holding the nozzle (61). During this process, the first reel (30) rotates around a horizontal axis, causing the first fire hose (60) wound around the first reel (30) to unwind. In addition, as the bobbin mounting pipe (25) on which the first reel (30) is installed rotates naturally around a vertical axis in the direction the first fire hose (60) is being pulled, the first fire hose (60) unwinds smoothly without getting caught.
[0135] As described above, when the facility manager arrives at the fire scene and the other facility manager opens the angle valve (50), the firefighting water flows into the first shaft pipe (31) through the connecting hose (51) and the connecting pipe (32), and the firefighting water flowing into the first shaft pipe (31) flows into the first fire hose (60) through the first branch pipe (31a), and the firefighting water flowing into the first fire hose (60) is sprayed into the surroundings through the nozzle (61) to quickly suppress the fire.
[0136] Meanwhile, the first door (12), which was separated from the first enclosure (11), can be placed near the fire scene or around the fire hydrant box (10). As shown in FIG. 11, the door support (13) is unfolded so that the first door (12) can be installed, and the first door (12) is supported by the door support (13). When the operation switch (132) is pressed to turn ON, power from the power supply unit (131) is supplied to the display (134) through the operation switch (132), and the display (134) receives power and visually displays an evacuation direction arrow.
[0137] At this time, if the user wishes to switch to a different direction because the evacuation direction displayed on the display (134) is displayed in the opposite direction, the user presses the direction selection switch (133), and the evacuation direction arrow displayed on the display (134) is switched to the opposite direction.
[0139] Meanwhile, when a fire approaches a fire hydrant box (10) where a facility manager is waiting while the fire is being extinguished using the first fire hose (60), as shown in FIG. 12, the first door (12) is moved near the fire hydrant box (10), and then the first door (12) is positioned toward the direction in which the fire is approaching, and as shown in FIG. 11, the viewing window (16) is rotated so that the mounting hole (12b) is opened.
[0140] Next, as illustrated in FIG. 9, the facility manager opens the second door (23b) of the sub-box (23) and, while holding the spray gun (71) stored in the sub-box (23), pulls the second fire hose (70) connected to the spray gun (71). As the second hose reel (40) rotates around the vertical axis, the second fire hose (70) wound on the second hose reel (40) is unwound.
[0141] When the facility manager opens the pressure regulating pressure reducing valve (80) while holding the spray gun (71), high-pressure firefighting water flows into the second shaft pipe (41) in a state where it is reduced by the pressure regulating pressure reducing valve (80) while passing through the bobbin mounting pipe (25), and the incoming firefighting water flows into the second fire hose (70) through the second branch pipe (41a), and the reduced-pressure firefighting water flowing into the second fire hose (70) is sprayed through the spray gun (71) to suppress the fire in the surrounding area.
[0142] Meanwhile, when attempting to suppress a fire while holding the spray gun (71) in a mounted state, as shown in FIG. 12, the facility manager hooks the tip of the spray gun (71) into the mounting hole (12b) and the other end onto the mounting stand (15). Then, the spray gun (71) is mounted by the mounting hole (12b) and the mounting stand (15). In this mounted state, firefighting water is sprayed from the spray gun (71), thereby suppressing the fire in the surrounding area and allowing the facility manager to proceed with other work tasks.
[0143] In addition, depending on the placement angle of the spray gun (71), fire suppression at both long and short distances is possible. When the spray gun (71) is mounted with the spray gun support (14) attached to the middle height adjustment groove (13a), the spray gun (71) is positioned horizontally. When the spray gun (71) is mounted with the spray gun support (14) attached to the upper height adjustment groove (13a), the discharge port of the spray gun (71) is positioned at a downward slope (firefighting water is fired at a short distance compared to when the spray gun is in a horizontal state). When the spray gun (71) is mounted with the spray gun support (14) attached to the lower height adjustment groove (13a), the discharge port of the spray gun (71) is positioned at an upward slope (firefighting water is fired at a long distance compared to when the spray gun is in a horizontal state). Therefore, firefighting water can be sprayed at various angles depending on the location of the fire (ceiling, wall, floor, long distance, short distance), which is very It is useful.
[0145] According to the present embodiment, since the first door (12) can be separated from the first enclosure (11), interference with the door (12) can be fundamentally prevented when the first fire hose (50) is pulled out, allowing the fire hose (50) to be pulled out quickly in any direction and the fire to be extinguished. Additionally, since the separated door (12) can be set up like a signboard using a support (13), the evacuation direction can be visually indicated to the evacuee, thereby inducing safe evacuation.
[0147] According to the present embodiment, after separating the first door (12) from the first enclosure (11), the separated first door (12) is set up like a signboard using a door support (13), and the evacuation direction is indicated through an evacuation route guide unit (130) installed on the first door (12), so that the evacuation direction can be intuitively checked in an emergency situation, thereby having the effect of inducing rapid evacuation.
[0148] In addition, when a fire approaches the vicinity of the fire hydrant box (10), the user can directly extinguish the fire using the fire extinguishing water discharged from the spray gun (71) while holding the spray gun (71), or indirectly extinguish the fire using the fire extinguishing water discharged from the spray gun (71) while the user mounts the spray gun (71) on the mounting hole (12b) and the mounting stand (15), thereby contributing to rapid fire suppression.
[0149] In addition, since the first door (12) is separated from the first enclosure (11) and the first fire hose (60) is pulled out with the first door (12) removed, interference with the first door (12) can be fundamentally prevented, allowing the first fire hose (60) to be pulled out quickly in any direction and the fire to be extinguished.
[0150] In addition, since the bobbin mounting tube (25) rotates around a vertical axis and the first hose reel (30) is installed on the bobbin mounting tube (25) and rotates around a horizontal axis, when the first fire hose (60) is pulled out, the position of the first fire hose (60) naturally changes in the direction of the pull-out and helps to unwind easily. This allows the user to use the first fire hose (60) without considering the pull-out direction, and also fundamentally resolves the problem of the first hose reel (30) getting caught during the pull-out process of the first fire hose (60), thereby greatly improving convenience of use.
[0152] Although the present invention has been described in detail only with respect to the specific embodiments described, it is obvious to those skilled in the art that various modifications and variations can be made within the scope of the technical spirit of the invention, and such modifications and variations are naturally included in the appended claims.
