Description
Technology Field
[0001] The present invention relates to a sprinkler-equipped multi-functional fire prevention device. Background Technology
[0002] Generally, a 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.
[0003] 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.
[0004] 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.
[0005] 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
[0006] 1. Republic of Korea Registered Patent No. 10-1761721 2. Republic of Korea Registered Patent No. 10-2557987 The problem to be solved
[0007] The purpose of the present invention is to provide a sprinkler-equipped multi-functional fire prevention device that can guide safe evacuation while blocking evacuees from moving toward the fire by separating the first door from the first enclosure and then standing the separated first door upright using a door support.

[0042] Since the present invention has a structure in which the first door can be separated from the first enclosure, interference with the door can be fundamentally prevented when the first fire hose is withdrawn, allowing the fire hose to be quickly withdrawn in any direction and the fire to be extinguished. Additionally, because the separated door can be stood upright like a signboard using a support, it is easy to store and can block access by evacuees, making it very useful.
[0043] 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.
[0044] In addition, it is very useful in that, when a fire approaches the fire hydrant cabinet or its vicinity while the first fire hose is in use, the fire around the fire hydrant cabinet can be suppressed through the spray of the second fire hose and the sprinkler of the sprinkler assembly.
[0045] 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.

Specific details for implementing the invention
[0048] The following is a detailed explanation based on the attached drawings.
[0050] FIG. 1 is a bottom perspective view of a sprinkler-equipped multi-functional fire prevention device according to the present invention with the first door closed, FIG. 2 is a perspective view of a sprinkler-equipped multi-functional fire prevention device according to the present invention with the first and second doors open, FIG. 3 is a front view of a sprinkler-equipped multi-functional fire prevention device according to the present invention with the first and second doors open, FIG. 4 is a partial side cross-sectional view of a sprinkler-equipped multi-functional fire prevention device according to the present invention, FIG. 5 is a plan cross-sectional view showing part “A” of FIG. 4 separately, FIG. 6 is an exploded perspective view showing the first door separately in a sprinkler-equipped multi-functional fire prevention device according to the present invention, and FIG. 7 is an exploded perspective view showing the sprinkler assembly separately in a sprinkler-equipped multi-functional fire prevention device according to the present invention.
[0052] Referring to FIGS. 1 to 7, the sprinkler-equipped multi-functional fire prevention 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 first pressure regulating pressure reducing valve (80), a sprinkler assembly (90), a second pressure regulating pressure reducing valve (100), a transmitter push switch (110), a control unit (120), a speaker (130), and a warning light unit (140). According to this, when a fire approaches the vicinity of the fire hydrant box (10), the user may directly extinguish the fire using the fire extinguishing water discharged from the spray gun (71) while holding the spray gun (71), or the user may separate from the first box (11) and set up a signboard-style device. There is a technical feature that allows the fire to be extinguished indirectly through the firefighting water discharged from the spray gun (71) while the spray gun (71) is mounted in the mounting hole (12b) and mounting bracket (15) of the first door (12), thereby contributing to rapid fire suppression, and the fire can be extinguished even more quickly because the sprinkler (93) of the sprinkler assembly (90) can be moved together with the firefighting water discharged from the spray gun (71) to suppress the fire intensively, and the fire can be extinguished even more quickly because 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, thereby fundamentally preventing interference with the first door (12), so the first fire hose (60) can be pulled out quickly in any direction and the fire can be extinguished.
[0054] 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).
[0055] 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.
[0056] The first door (12) is installed in a hinged manner on the first housing (11) and serves to open and close the front opening of the first housing (11). On the side of the first door (12), a connector (12a) is installed at the top, bottom, and middle sections, and the connector (12a) is detachably connected to a round bar (11a) and rotates around the round bar (11a). Additionally, a circular mounting hole (12b) is formed on the front of the first door (12) to communicate with the interior of the first housing (11), a pin hole (12c) is integrally formed on both sides of the top section, and a handle (12d) is formed on the front to allow the first door (12) to be easily opened and closed.
[0057] Referring to FIG. 5, the separation and connection between the first housing (11) and the first door (12) can be explained as follows: when the first door (12) is opened so that the first housing (11) and the first door (12) are perpendicular to each other, the first door (12) is pushed strongly backward, and the connection between the rod (11a) and the connector (12a) is released and 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 between the first housing (11) and the first door (12) can be performed in the reverse order of the method described above.
[0058] 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 present 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). The upper part of the door support (13) is formed to be tapered at a predetermined angle so that the unfolding angle is limited by this, and height adjustment grooves (13a) are formed at regular intervals along the vertical length direction on one side of the door support (13).
[0059] The above-mentioned spray gun support (14) is a rectangular block, and at one end, a fitting projection (14a) is integrally formed that is detachably coupled to the height adjustment groove (13a). The spray gun support (14) is detachably coupled to the height adjustment groove (13a) via the fitting projection (14a) and supports the spray gun (71) while adjusting the mounting angle of the spray gun (71).
[0060] 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).
[0061] 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).
[0062] 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).
[0063] 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.
[0064] Additionally, the separated first door (12) can be used in a standing position using the door support (13) to mount the spray gun (71). To explain this in more detail, 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. 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. Therefore, it is very useful as it allows firefighting water to be sprayed at various angles depending on the location of the fire (ceiling, wall, floor, distant, near).
[0066] Referring to FIGS. 2 to 4, the transfer unit (20) is composed of a guide part (21), a first 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) to allow the first thruster (30) and the second thruster (40) to be withdrawn from the fire hydrant box (10) or stored in the fire hydrant box (10), and it serves to allow the first thruster (30) to rotate around a vertical axis.
[0067] The above guide section (21) and the first 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 first rail section (22) is installed so as to be slidable in the forward and backward directions on the guide section (21).
[0068] The above sub-box (23) is composed of a second housing (23a) and a second door (23b). In the case of the present embodiment, it is installed on the upper surface of the first rail section (22) and moves together with the movement of the first rail section (22) to be withdrawn from the fire hydrant box (10) to the outside or stored in the fire hydrant box (10). Inside this sub-box (23), a second hose reel (40) with a second fire hose (70) wound around it is stored.
[0069] The above stopper (24) is installed on the lower surface of the sub-box (23) so as to be positioned between the first rail section (22) and serves to limit the excessive withdrawal of the sub-box (23). For example, during the process of withdrawing the sub-box (23) via the first rail section (22), the stopper (24) gets caught on the inner lower part of the first box (11), thereby limiting the withdrawal of the sub-box (23).
[0070] The bobbin mounting tube (25) is a pipe bent in multiple stages, and in the present embodiment, the lower end is installed to penetrate the upper surface of the sub-box (23) and rotate around a vertical axis. For example, the bobbin mounting tube (25) is installed upright on the sub-box (23), and the lower end is installed on the sub-box (23) via a bearing so as to rotate clockwise or counterclockwise around a vertical axis. At the upper end of the bobbin mounting tube (25), the first shaft tube (31) of the first thruster (30) is installed via a first anti-twist means (TP1) so as to rotate clockwise or counterclockwise around a 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 a third anti-twist means (TP3) so as to rotate clockwise or counterclockwise around a vertical axis. 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).
[0071] 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 (rotates) in the direction of the first fire hose (60) being pulled out, thereby helping to easily unwind it. This allows the user to use the first fire hose (60) without considering the direction of the first fire hose (60) being pulled out, and also fundamentally resolves the problem of the first hose reel (30) getting caught during the process of pulling out the first fire hose (60), thereby greatly improving convenience of use.
[0073] 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).
[0074] 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. A first branch tube (31a) is integrally formed on the outer surface of the first shaft tube (31) and communicates with the interior of the first shaft tube (31), and one end of the first fire hose (60) is detachably connected to the first branch tube (31a).
[0075] The above connecting pipe (32) is an elbow pipe, and one end is rotatably installed via 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. A connecting hose (51) of an angle valve (50) is detachably connected to the other end of the connecting pipe (32).
[0076] 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).
[0078] 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).
[0079] 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 manner rotates clockwise or counterclockwise around a vertical axis. A second branch tube (41a) is integrally formed on the outer surface of the second shaft tube (41) and communicates with the interior of the second shaft tube (41), and one end of the second fire hose (70) is detachably connected to the second branch tube (41a).
[0080] 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).
[0082] 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.
[0083] This angle valve (50) is equipped with a connecting hose (51) that is interconnected with a connecting pipe (32) and a fire water supply pipe (52) that is embedded in a wall (W), with one end interconnected with the angle valve (50) and the other end protruding outward through the wall (W). When the angle valve (50) is opened, fire water is supplied simultaneously to the connecting hose (51) and the fire water supply pipe (52).
[0084] The firefighting water supplied through the above connecting hose (51) 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 through the first shaft pipe (31) is supplied to the first fire hose (60) through the first branch pipe (31a), and the firefighting water supplied through the second shaft pipe (41) is supplied to the second fire hose (70) through the second branch pipe (41a).
[0085] In addition, the firefighting water supplied through the firefighting water supply pipe (52) is supplied sequentially through the firefighting water supply pipe (52) → third fire hose (94) → sprinkler (93).
[0087] 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. The first fire hose (60) is provided with a nozzle (61) at one end 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).
[0088] 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).
[0090] 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. The second fire hose (70) is provided with a spray gun (71) at one end and the other end is detachably connected to the second branch pipe (41a) to receive depressurized firefighting water through the second branch pipe (41a) and spray firefighting water through the spray gun (71). A catch (71a) is provided on the spray gun (71) to prevent the spray gun (71) from being unintentionally detached from the stand (15).
[0091] 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).
[0093] Meanwhile, the second fire hose (70) is used as a temporary measure in conjunction with a sprinkler (93) 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).
[0094] Therefore, since the firefighting water supplied to the second fire hose (70) or sprinkler (93) does not need to be supplied with high-pressure 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 third fire hose (94) connected to the second fire hose (70) and sprinkler (93), there is a risk that the second fire hose (70) and the third fire hose (94) will burst because they cannot withstand the pressure.
[0095] Accordingly, in this embodiment, the first pressure regulating pressure reducing valve (80) and the second pressure regulating pressure reducing valve (100) are applied to resolve such problems.
[0096] Referring to FIGS. 3 and 4, the first 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 passing through the bobbin mounting pipe (25) and discharge it into the second shaft pipe (41).
[0097] As described above, the firefighting water reduced in pressure by the first 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.
[0098] Referring to FIGS. 3, 4, and 7, the second pressure regulating pressure reducing valve (100) is a known pressure reducing valve, and in the case of this embodiment, it is installed in the fire water supply pipe (52) and serves to reduce the pressure of the fire water passing through the fire water supply pipe (52) and discharge it to the third fire hose (94).
[0099] As described above, the problem of damage to the third fire hose (94) caused by high pressure can be easily resolved as the fire water reduced by the second pressure regulating pressure reducing valve (100) is supplied to the third fire hose (94).
[0101] Referring to FIGS. 1 and 7, the sprinkler assembly (90) is composed of a second rail section (91), a plurality of movable blocks (92), a sprinkler (93), and a third fire hose (94). In the case of this embodiment, it is movably installed on the ceiling (C) and serves to quickly suppress a fire approaching the fire hydrant box (10) together with the spray gun (71) of the second fire hose (70).
[0102] The second rail section (91) serves to guide a plurality of movable blocks (92) that are installed on the ceiling (C) to be movable. For example, when installing such a second rail section (91) in a corridor of a building, it is preferable to install it in the middle of the ceiling (C) along the length direction of the corridor.
[0103] The above plurality of movable blocks (92) are installed to be individually movable on the second rail section (91). For example, a sprinkler (93) is installed on one of the plurality of movable blocks (92), and a third fire hose (94) is inserted and mounted through the remaining movable blocks (92) with sufficient length.
[0104] The above sprinkler (93) is installed on the movable block (92) and receives depressurized firefighting water to spray firefighting water. Since this sprinkler (93) is a widely known technology in the field, a detailed description thereof will be omitted.
[0105] Meanwhile, a traction rope (L) may be installed in the sprinkler (93), and when a user pulls the traction rope (L), the moving block (92) on which the sprinkler (93) is installed moves along the second rail section (91).
[0106] The above third fire hose (94) serves as a medium for connecting the fire water supply pipe (52) and the sprinkler (93). In this embodiment, it is mounted by being inserted through the movable block (92) with sufficient length, and one end is connected to the fire water supply pipe (52), and the other end is connected to the sprinkler (93).
[0107] For example, when the sprinkler (93) is pulled using the above-mentioned traction rope (L), the movable block (92) on which the sprinkler (93) is installed moves along the second rail section (91), and as the third fire hose (94) is pulled by the movement of the sprinkler (93), the movable block (92) on which the third fire hose (94) is mounted moves sequentially along the second rail section (91), and the third fire hose (94) that was folded is unfolded by such movement.
[0108] When the second pressure regulating pressure reducing valve (100) is opened in the above state, the firefighting water flowing along the firefighting water supply pipe (52) is discharged in a reduced pressure state and supplied to the third fire hose (94), the firefighting water supplied to the third fire hose (94) is supplied to the sprinkler (93), and the firefighting water supplied to the sprinkler (93) is sprayed through the sprinkler (93) to quickly suppress the fire.
[0109] According to the present embodiment, when a fire approaches the fire hydrant box (10) or its vicinity while the first fire hose (60) is in use, the fire around the fire hydrant box (10) can be suppressed through the spray (71) of the second fire hose (70) and the sprinkler (93) of the sprinkler assembly (90).
[0111] Meanwhile, the above second pressure regulating pressure reducing valve (100) is replaced by the preceding description.
[0113] Referring to FIGS. 1 to 3, the transmitter push switch (110), control unit (120), speaker (130), and warning light unit (140) are described as follows.
[0114] The above-mentioned transmitter push switch (110) 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 (120).
[0115] The above control unit (120) receives a fire signal from the transmitter push switch (110) and controls the operation of the speaker (130) and the warning light unit (140), respectively. For example, when a fire signal is input to the control unit (120) from the transmitter push switch (110), the control unit (120) transmits the fire signal to a control room where a manager is stationed, controls the operation of the speaker (130) so that a fire warning sound is output from the speaker (130), and controls the operation of the warning light unit (140) so that a red light is turned on (or flashes) from the warning light unit (140).
[0116] The above speaker (130) is installed on the front of the fire hydrant box (10) and is operated by the control unit (120) to output a fire warning sound such as a voice (e.g., fire!) or a siren.
[0117] The above warning light unit (140) is installed on the front of the fire hydrant box (10) and is operated by the control unit (120) to light up (or flash) a red light.
[0119] FIGS. 8 to 14 are drawings for explaining the effects of a sprinkler-equipped multi-functional fire prevention device according to the present invention, and with reference thereto, the explanation is as follows.
[0120] When a fire occurs in a building and a fire discoverer presses the alarm button (110), a fire signal is output from the alarm button (110) and input to the control unit (120). The control unit (120) receives the fire signal and transmits it to a control room where an administrator is stationed, and also controls the operation of the speaker (130) and the warning light unit (140).
[0121] The above speaker (130) is controlled by the control unit (120) to output a fire warning sound such as a voice (e.g., fire!) or a siren, and the warning light unit (140) is controlled by the control unit (120) to turn on (or flash) a red light.
[0122] 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. 8 to 11, 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).
[0123] 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.
[0124] As described above, when the facility manager arrives at the scene of the fire and the other facility manager opens the angle valve (50), the firefighting water is supplied simultaneously through the connecting hose (51) and the firefighting water supply pipe (52). The firefighting water supplied through the connecting hose (51) flows into the first shaft pipe (31) via 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). The firefighting water flowing into the first fire hose (60) is sprayed around through the nozzle (61) to quickly suppress the fire.
[0125] In addition, the first door (12) that was separated from the first enclosure (11) can be placed near the fire scene or around the fire hydrant box (10).
[0127] 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 the viewing window (16) is rotated so that the mounting hole (12b) is opened.
[0128] Next, as illustrated in FIG. 10, 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.
[0129] When the facility manager opens the first 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 first 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.
[0130] 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.
[0131] 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.
[0133] Meanwhile, as illustrated in FIG. 14, if the flames are not completely extinguished even though the fire is being suppressed using the spray gun (71) of the second fire hose (70), the user can suppress the fire using the sprinkler (93) of the sprinkler assembly (90), which is explained in detail as follows.
[0134] First, when a facility manager pulls the sprinkler (93) using a traction rope (L), the movable block (92) on which the sprinkler (93) is installed moves along the second rail section (91), and as the third fire hose (94) is pulled by the movement of the sprinkler (93), the movable block (92) on which the third fire hose (94) is mounted moves sequentially along the second rail section (91), and the third fire hose (94) that was folded is unfolded by this movement.
[0135] When the second pressure regulating pressure reducing valve (100) is opened in the above state, the firefighting water flowing along the firefighting water supply pipe (52) is discharged in a reduced pressure state and supplied to the third fire hose (94), the firefighting water supplied to the third fire hose (94) is supplied to the sprinkler (93), and the firefighting water supplied to the sprinkler (93) is sprayed through the sprinkler (93) to quickly suppress the fire.
[0136] In the case of this embodiment, it is described and illustrated that if the fire cannot be extinguished by the spray gun (71), the fire is extinguished using the sprinkler (93) of the sprinkler assembly (90), but if necessary, the sprinkler (93) of the sprinkler assembly (90) may be prepared in advance before the fire enters the fire hydrant box (10).
[0138] 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, the separated door (12) can be set up like a signboard using a support (13), making it easy to store and very useful for blocking access by evacuees.
[0139] 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.
[0140] In addition, it is very useful in that when a fire approaches the fire hydrant box (10) or its vicinity while the first fire hose (60) is in use, the fire around the fire hydrant box (10) can be suppressed through the spray gun (71) of the second fire hose (70) and the sprinkler (93) of the sprinkler assembly (90).
[0141] 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.
[0143] 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.
