Description

rotary extinguishing device

[0001] The present invention relates to a fire extinguishing device for extinguishing flames generated inside a panel such as an electrical room.

[0002] Panels for power control and management are installed in various spaces (hereinafter referred to as “electrical rooms, etc.”) including electrical rooms, electrical and electronic rooms, and designated rooms where electrical devices, control devices, and servers are located, both inside and outside the building.

[0003] In the case of an electrical room with multiple panels, if a fire breaks out, significant losses may occur if access to the area is blocked and the fire cannot be quickly extinguished.

[0004] When considering fire extinguishing devices installed in electrical rooms and other locations to suppress fires, sprinkler systems are typically used in buildings. A sprinkler system is a device that, when the indoor or surrounding temperature exceeds the sprinkler's preset temperature, the head nozzles installed at the sprinkler's tip open, spraying a extinguishing agent to extinguish the fire.

[0005] Sprinkler systems are installed on the ceiling of a building and are suitable for extinguishing fires in the entire building or in open spaces, but they are not effective for extinguishing fires in confined spaces such as the interior of panels installed in electrical rooms.

[0006] Additionally, there is a method of extinguishing a fire by installing a simple sprinkler inside the panel as a fire extinguishing device for distribution, but this technology also sprays the fire extinguishing agent from above, and there is a problem that the fire extinguishing agent cannot sufficiently reach the point of fire due to the curvature of the inside of the panel.

[0007] In this way, existing fire extinguishing devices have limitations in that they cannot completely extinguish fires inside panels even when spraying extinguishing agents, and as a result, there is a problem in that fires remaining inside panels can spread again throughout the building.

[0008] Therefore, a device is needed that can quickly extinguish a fire by effectively spraying fire extinguishing agents at the location of a fire inside a panel such as an electrical room.

[0009] The present invention is intended to solve the above-described problem and to provide a rotary fire extinguishing device that can effectively extinguish a major fire outbreak point by avoiding bending inside the panel.

[0010] In order to solve the above-described problem, the rotary fire extinguishing device of the present invention comprises a fire extinguisher provided on one side of a panel and supplying a fire extinguishing agent, a fire extinguishing device installed on the inner upper part of the panel, and a first tube having one end connected to the fire extinguishing agent and the other end connected to the fire extinguishing device to guide the fire extinguishing agent to the fire extinguishing device, wherein the fire extinguishing device includes a fixed part installed and fixed on the inner upper part of the panel and a rotating part detachably connected to the fixed part, and when the fire extinguishing agent is supplied from the fire extinguisher, the rotating part may be configured to separate from the fixed part, descend, rotate, and spray the fire extinguishing agent to extinguish a fire.

[0011] In one embodiment of the present invention, the rotating part may rotate at a pressure that sprays the extinguishing agent.

[0012] In one embodiment of the present invention, the rotating part may be connected to the fixed part by rotating in one direction, and separated from the fixed part by rotating in the other direction.

[0013] In one embodiment of the present invention, the fixed part may include a fixed body installed and fixed on the inner upper part of the panel, and a second tube having one end connected to the other end of the first tube inside the fixed body to guide the extinguishing agent to the rotating part.

[0014] In one embodiment of the present invention, the second tube may be stored inside the fixed body while the rotating part is connected to the fixed part.

[0015] In one embodiment of the present invention, the second tube may include at least one first injection hole through which the extinguishing agent can be injected on the outer surface.

[0016] In one embodiment of the present invention, the second tube may be thinner than the first tube.

[0017] In one embodiment of the present invention, the rotating part may include at least one rotating connection part that is connected to the other end of the second tube and rotates independently with respect to the second tube, a rotating body that is connected to the rotating connection part and rotates together with the rotating connection part and is detachably connected to the fixed body, and a rotating blade that has one end connected to the rotating body and communicates with the second tube, and the other end extending away from the rotating body.

[0018] In one embodiment of the present invention, the rotary blade may include at least one second injection hole that injects the extinguishing agent in a tangential direction of a circle centered on the rotational axis of the rotary body, and may rotate the rotary part with the pressure for injecting the extinguishing agent.

[0019] In one embodiment of the present invention, the fire extinguishing device may further include a lighting unit.

[0020] The present invention has the advantage of positioning the fire extinguishing device at a critical fire occurrence point within the panel to avoid bending according to the above-described configuration and connection relationship, and effectively extinguishing the fire through rotary spraying.

[0021] Additionally, it has the advantage of efficiently utilizing the space inside the panel when combined with lighting devices that are generally installed inside the panel.

[0033] Fig. 1 is an exemplary diagram showing an inactive state of a rotary fire extinguishing device according to an embodiment of the present invention. Fig. 2 is an exemplary diagram showing an operating state of a rotary fire extinguishing device according to an embodiment of the present invention.

[0034] Referring to FIGS. 1 and 2, the present invention can effectively suppress a fire inside a panel (10) installed in an electrical room or the like, and can include a fire extinguisher (100) that supplies a fire extinguishing agent, a first tube (300) that guides the fire extinguishing agent supplied by the fire extinguisher (100) to a fire extinguishing device (200), and a fire extinguishing device (200) that receives the fire extinguishing agent and sprays it to the point where a fire has occurred.

[0035] In one embodiment of the present invention, the fire extinguishing device (200) may include a fixed part (210) that is installed and fixed inside the panel (10) and supports the rotation of a rotating part (220) that is directly or indirectly connected thereto, and may also include a rotating part (220) that is detachably connected to the fixed part (210) so that when a fire occurs, it is separated from the fixed part (210), descends, rotates, and sprays a fire extinguishing agent.

[0036] Specifically, referring to FIG. 1, when a fire does not occur and the fire extinguishing device (200) is in an inactive state where it does not spray a fire extinguishing agent, the rotating part (220) can be connected to the fixed part (210) and positioned at the upper part inside the panel (10). Referring to FIG. 2, which shows an operating state where a fire occurs and the fire extinguishing device (200) sprays a fire extinguishing agent, the rotating part (220) is separated from the fixed part (210), descends, rotates, and sprays a fire extinguishing agent, thereby effectively extinguishing a fire that occurred at a point where it descended inside the panel (10).

[0037] In addition, the second tube (212) to be described later connects the fixed part (210) installed on the upper part of the panel (10) and the rotating part (220) separated from the fixed part (210) and lowered, and sprays the fire extinguishing agent through the first injection hole (213) formed on the outer surface, so that it has the advantage of being able to effectively extinguish a fire without any missing points from the upper part of the panel (10) to the lower part of the panel (10).

[0038] Hereinafter, each component of a fire extinguishing device (200) according to one embodiment of the present invention will be examined in detail with reference to FIGS. 1 to 5.

[0039] Fig. 3 is an exploded perspective view illustrating a detailed configuration of a fire extinguishing device according to one embodiment of the present invention. Fig. 4 illustrates a method for separating a fixed portion and a rotating portion in a fire extinguishing device according to one embodiment of the present invention. Fig. 5 is a drawing illustrating an operating state of a fire extinguishing device according to another embodiment of the present invention.

[0040] Fire extinguisher (100)

[0041] The fire extinguisher (100) has a built-in fire extinguishing agent and discharges the fire extinguishing agent at high pressure. The fire extinguishing agent can be supplied to the fire extinguishing device (200) through the first tube (300) connected to the fire extinguisher (100).

[0042] A fire extinguisher (100) may be installed on one side of a panel (10) installed in an electrical room, etc. As an example, the fire extinguisher (100) may be installed on the outside of the panel (10) as illustrated in FIG. 1. However, the present invention is not limited thereto and may also be installed inside the panel (10) depending on the size of the internal space of the panel (10) or the environment in which the panel (10) is installed.

[0043] <Tube 1 (300)>

[0044] The first tube (300) has one end connected to the fire extinguisher (100) and the other end connected to the fire extinguishing device (200), and serves to guide the fire extinguishing agent discharged at high pressure from the fire extinguisher (100) to the fire extinguishing device (200). As an example, as shown in Fig. 1, the first tube (300) may have one end connected to the fire extinguisher (100) located outside the panel (10) by penetrating the panel (10), and the other end connected to the fixing part (210) of the fire extinguishing device (200).

[0045] <Fire extinguisher (200)>

[0046] A fire extinguishing device (200) is a device installed on a panel (10) installed in an electrical room, etc., and sprays a fire extinguishing agent into the interior of the panel (10). As an example, it may be installed on the upper part of the inner side of the panel (10) as illustrated in Fig. 1. However, the present invention is not limited thereto.

[0047] The fire extinguishing device (200) has a first tube (300) connected to one side to receive fire extinguishing agent from the fire extinguisher (100) and sprays the supplied fire extinguishing agent to the point of fire to be extinguished.

[0048] A rotary fire extinguishing device (200) according to one embodiment of the present invention may include a fixed part (210) and a rotating part (220).

[0049] The fixed part (210) is installed and fixed on the inside of the panel (10), receives a fire extinguishing agent from the first tube (300) connected to one side, guides the supplied fire extinguishing agent to the rotating part (220), and supports the rotating part (220) connected directly or indirectly to the other side so that it can rotate.

[0050] In one example, the fixed part (210) may include a fixed body (211) and a second tube (212), and in some cases, may further include a connector (215).

[0051] The fixed body (211) can support the rotating part (220) connected to the fixed body (211) so that it can be positioned on the upper part of the panel (10) when the rotating part (220) is connected to the fixed body (210) in an inactive state, and can store or house the second tube (212) to be described later when in an inactive state. To this end, the fixed body (211) can be installed and fixed on the inner upper part of the panel (10) and can be formed in a cylindrical shape. However, the present invention is not limited thereto.

[0052] In one embodiment, the fixed body (211) may be provided in a cylindrical shape having a diameter wider than the diameter of the second tube (212), thereby allowing the second tube (212) to be stored inside the fixed body (211).

[0053] In one embodiment, the fixed body (211) may be provided in a cylindrical shape having a diameter wider than the diameter of the rotating body (222) of the rotating part (220) to be described later, and accordingly, the rotating body (222) may be connected to the fixed body (211) in a manner in which it is inserted into the interior of the fixed body (211).

[0054] In addition, the inner side of the lower part of the cylindrical fixed body (211) may include a rotary coupling groove (211-1) (or female screw portion) and may be detachably connected to a rotary coupling protrusion (222-1) (or male screw portion) formed on the outer surface of the rotary body (222). However, this is not limited thereto.

[0055] In one embodiment, the fixed body (211) may further include a connecting member (214) for a rigid or detachable connection with the panel (10), and may be indirectly connected to and fixed to the panel (10) through the connecting member (214). For example, the connecting member (214) may be a bracket or the like.

[0056] Referring to FIGS. 1 to 4, in one embodiment, the fixed body (211) can be indirectly connected to the panel (10) through a connecting member (214) that is provided with a larger area than the fixed body (211) and is rigidly connected to the panel (10).

[0057] The second tube (212) can serve to guide the extinguishing agent to the rotating part (220) and to rotatably support the rotating part (220). To this end, one end of the second tube (212) can be directly or indirectly connected to the first tube (300), and the other end of the second tube (212) can be directly or indirectly connected to the rotating part (220).

[0058] Referring to FIG. 3, in one embodiment, the second tube (212) is connected to the first tube (300) through a connector (215) at one end inside the fixed body (211), and the other end can be connected to a rotational connection part (221) of a rotational part (220) to be described later. However, this is not limited thereto.

[0059] The second tube (212) can effectively suppress a fire occurring in the section from the inner upper part of the panel (10) to the rotating part (220) connected to the lower part by spraying the fire extinguishing agent guided from the first tube (300). To this end, the second tube (212) can include at least one first spray hole (213) on the outer surface through which the fire extinguishing agent can be sprayed.

[0060] The first injection hole (213) may be a micro hole provided on the outer surface of the second tube (212) and may penetrate the inside and outside of the second tube (212). In one embodiment, a plurality of first injection holes (213) may be provided on the outer surface of the second tube (212), and may be uniformly arranged on the outer surface of the second tube (212) so that the second tube (212) does not rotate or shake during the process of discharging the extinguishing agent through the first injection hole (213).

[0061] In one embodiment, the second tube (212) may be formed as a tube having a smaller diameter than the first tube (300). Accordingly, even if the supply pressure of the extinguishing agent guided from the first tube (300) to the rotating part (220) through the second tube (212) is partially reduced due to the first injection hole (213) of the second tube (212), the injection pressure at the second injection hole (224) can be sufficiently formed.

[0062] The connector (215) serves to connect the first tube (300) and the second tube (212) and to support the axis of the second tube (212) so that it is positioned at the center of the fixed body (211). To this end, the connector (215) may be installed and fixed inside the fixed body (211) or may be formed integrally with the fixed body (211), and may be formed in a form in which the other end of the first tube (300) can be connected to one side and one end of the second tube (212) can be connected to the other side.

[0063] Referring to FIG. 3, in one embodiment, the connector (215) is positioned inside the fixed body (211) and is provided as a tube bent in an 'ㄱ' shape, with one end of the first tube (300) connected to the other end, and the other end of the connector (215) is positioned so that the central axis of the tube coincides with the central axis of the cylindrical fixed body (211) and can be connected to one end of the second tube (212). However, this is not limited thereto.

[0064] When the extinguishing agent is supplied from the fire extinguisher (100), the rotating part (220) is separated from the fixed part (210) and descends, and while rotating, sprays the extinguishing agent. In one embodiment, the rotating part (220) may rotate with the pressure to spray the extinguishing agent. To this end, the rotating part (220) may include a rotating connection part (221), a rotating body (222), and a rotating blade (223).

[0065] The rotary connecting part (221) is positioned between the second tube (212) and the rotary body (222), and connects the rotary body (222) so that it can rotate independently with respect to the second tube (212), and is connected to the second tube (212) to guide the extinguishing agent guided by the second tube (212) to the rotary body (222). To this end, the rotary connecting part (221) is provided as a cylindrical member including a bearing or the like, and the other end of the second tube (212) can be connected, and the rotary body (222) can be connected to the other end. However, the present invention is not limited thereto.

[0066] The rotary body (222) is connected to the rotary connection part (221) and rotates independently with respect to the second tube (212), and serves to guide the extinguishing agent to the rotary blade (223) that is connected to the outer surface of the rotary body (222) and communicates with the second tube (212). To this end, the rotary body (222) may be provided in a tubular shape that shares a rotary axis with the rotary connection part (221).

[0067] Referring to FIGS. 3 to 5, in one embodiment, the rotary body (222) may be provided in a cylindrical shape that shares a rotary axis with the rotary connecting part (221) and is connected to the second tube (212). However, the present invention is not limited thereto.

[0068] The rotating body (222) is detachably connected to the fixed body (211), and is connected to the fixed body (211) in an inactive state in which the extinguishing agent is not sprayed, and is separated from the fixed body (211) in an operating state in which the extinguishing agent is sprayed. In one embodiment, the rotating body (222) may be connected to the fixed part (210) by rotating in one direction and separated from the fixed part (210) by rotating in the other direction.

[0069] To this end, the rotary body (222) may be provided in a form that corresponds to the fixed body (211) and can be inserted into the fixed body (211), and may include a coupling part corresponding to the rotary coupling part provided in the fixed body (211) on the outer surface.

[0070] Referring to FIG. 3, in one example, the rotating body (222) may be provided in a cylindrical shape having a diameter smaller than the inner diameter of the fixed body (211) provided in a cylindrical shape, and the outer circumferential surface of the rotating body (222) may include a rotating coupling protrusion (222-1) (e.g., a male screw portion) provided in a shape corresponding to a rotating coupling groove (211-1) (e.g., a female screw portion) provided on the inner side of the fixed body (211).

[0071] The rotary blade (223) sprays the extinguishing agent guided from the rotary body (222) and rotates the rotating part (220) with the spray pressure. To this end, the rotary blade (223) may have one end connected to the outer surface of the rotary body (222) and communicated with the second tube (212) and the rotary body (222), and the other end formed in a form extending away from the rotary body (222), and may include at least one second spray hole (224) on the outer surface for spraying the guided extinguishing agent.

[0072] In one embodiment, the rotary blade (223) may be provided in the form of a square pillar connected to the outer surface of a rotary body (222) provided in a cylindrical shape and communicating with the rotary body (222), and a plurality of rotary blades (223) provided in the same shape may be arranged in opposing positions with the rotation axis of the rotary body (222) interposed therebetween.

[0073] For example, referring to FIGS. 3 to 5, the first rotary blade (223-1) and the second rotary blade (223-2) are connected to the outer surface of the rotary body (222) and communicate with the rotary body (222), and are arranged in the same square pillar shape, and are arranged on a line that intersects the rotation axis of the rotary body (222) perpendicularly with the rotary body (222) in between.

[0074] Accordingly, the rotation of the rotating part (220) can be balanced. However, the present invention is not limited thereto, and the shape and extended length of the rotating blade (223) and the number of the rotating blades (223) can be modified according to the shape and size of the internal space of the panel (10) in which the rotating fire extinguishing device (200) according to the present invention is installed.

[0075] The second injection hole (224) is a hole provided on the outer surface of the rotary blade (223) and connects the inside and outside of the rotary blade (223), and the rotating part (220) rotates due to the injection pressure of the extinguishing agent injected through the second injection hole (224). To this end, the second injection hole (224) can be positioned to inject the extinguishing agent in the tangential direction of a circle centered on the rotation axis of the rotary body (222) on the outer surface of the rotary blade (223).

[0076] Additionally, in one embodiment, the second injection hole (224) may be positioned adjacent to the end of the rotary blade (223) that is away from the rotary body (222). Accordingly, a large rotational force can be generated for the rotation of the rotary part (220) with the rotary body (222) as the rotation axis.

[0077] A rotary fire extinguishing device according to one embodiment of the present invention may further include a lighting unit (230) as a component of the fire extinguishing device (200). It is common for a panel (10) installed in an electrical room or the like to be provided with a lighting device that illuminates the interior of the panel (10) so that a worker can perform his / her work.

[0078] Accordingly, in one embodiment of the present invention, as illustrated in FIGS. 1 to 5, a lighting unit (230) attached to a rotary blade (223) to illuminate the lower portion may be further included. However, the present invention is not limited thereto, and a lighting unit (230) may also be installed on a rotary body (222) or a fixed body (211), and a lighting unit (230) attached to a rotary blade (223) to illuminate the upper portion may also be included in the present invention.

[0079] A rotary fire extinguishing device according to one embodiment of the present invention has the advantage of efficiently using space while exhibiting both the fire extinguishing function and the lighting function required for the panel (10) by combining a lighting unit (230) with the fire extinguishing device (200).

[0080] Hereinafter, an operating method for extinguishing a fire by separating the rotating part (220) from the fixed part (210) and descending when a fire occurs and the rotary fire extinguishing device according to the present invention is operated will be described.

[0081] Referring to FIGS. 1, 2, 4 and 5, in an inactive state where no fire occurs inside the panel (10) and no extinguishing agent is sprayed, the rotating body (222) of the rotating part (220) and the fixed body (211) of the fixed part (210) are connected by a rotary joint, and when a fire occurs and the extinguishing agent is supplied from the fire extinguisher (100), the rotating part (220) rotates while the extinguishing agent is sprayed through the fire extinguisher (100), the first tube (300), the second tube (212), the rotating body (222), the rotating blade (223) and the second injection hole.

[0082] By the rotation of the rotating part (220), the rotating body (222) is separated from the fixed body (211) and descends, and continues to rotate from the descended position to spray the extinguishing agent. At the same time, the second tube (212) sprays the extinguishing agent through the first injection hole (213) to extinguish a fire occurring in the section between the fixed part (210) and the rotating part (220).

[0083] According to the aforementioned configuration and operating method, the rotary fire extinguishing device disclosed in the present invention can effectively extinguish a fire up to the lower part of the panel (10) where the fire extinguishing agent is difficult to reach due to the curve formed inside the panel (10) compared to the existing fire extinguishing device (200), and at the same time, has the advantage of continuously and effectively supplying the fire extinguishing agent from the upper part of the panel (10) to the lower part of the panel (10) where the rotating part (220) is located.

[0084] In addition, since the second tube (212) is built into the fixed body (211) and the lighting unit (230) is provided in an inactive state where the rotating unit (220) is connected to the fixed unit (210) without a fire occurring, even if the fire extinguishing device (200) is installed, there is an advantage in that all functions required inside the panel (10) can be maintained without excessively occupying the internal space of the panel (10) or narrowing the working space inside the panel (10).

[0085] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will readily appreciate that modifications to other specific forms can be made without altering the technical spirit or essential characteristics of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.

[0086] For example, although the present invention has been described with reference to an embodiment illustrated in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and variations of the embodiments are possible from this.

[0087] Therefore, the true technical protection scope of the present invention is indicated by the technical idea of ​​the patent claims described below, and all changes or modified forms derived from the image and scope of the patent claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
