[0022] FIG. 1 is a schematic diagram of the installation of a fire keeper according to one embodiment. Referring to FIG. 1, the fire keeper (100) can be installed in a facility (200). In this embodiment, the facility (200) may include a street light shown in FIG. 1 (a) or a tree shown in FIG. 1 (b). Such facility (200) is not limited to a street light or a tree, and any structure (e.g., a building) on ​​which the fire keeper (100) can be installed may be included in the facility (200).

[0023] Referring to FIG. 1(a), an example is illustrated in which a fire keeper (100) is installed on the top of a facility (200) serving as a street light. An enlarged portion illustrates the fire keeper (100) being activated and the fire extinguishing agent filled inside being discharged around the street light. When a fire occurs, the temperature rises and cracks form in the fire keeper (100), allowing the fire extinguishing agent to be discharged to the outside. The fire keeper (100) installed on the street light can be installed to respond to fires in the surrounding area.

[0024] Referring to FIG. 1(b), an example is illustrated in which a fire keeper (100) is installed on a facility (200) that is a tree. The enlarged portion illustrates the fire keeper (100) being activated and the fire extinguishing agent filled inside being discharged around the tree. When a fire occurs, the temperature rises and cracks form in the fire keeper (100), allowing the fire extinguishing agent to be discharged to the outside. The fire keeper (100) installed on the tree can be installed to respond to fires in the surrounding area as well as the tree itself.

[0025] In this embodiment, the fire keeper (100) can be installed on a facility (200) using various fixing members (not shown), such as screws, strings, and clamps. Additionally, the fire keeper (100) can be installed suspended from the ground on a facility (200).

[0026] In this embodiment, the fire keeper (100) is installed in an external environment, so it may be composed of an eco-friendly material that prevents human and ecological damage when it comes into contact with or flows into the soil.

[0027] FIG. 2 is an example diagram of a housing of a fire keeper according to one embodiment. In the following description, parts that overlap with the description of FIG. 1 will be omitted. Referring to FIG. 2, the fire keeper (100) may include a housing (110).

[0028] The housing (110) may be an outer case that protects the fire keeper (100) from external environments and ensures that the fire extinguishing agent and non-combustible agent filled in the fire keeper (100) are properly maintained. The shape of the housing (110) may be determined according to the location and function where it is to be installed. Basic shapes of the housing (110) include box-shaped (cuboidal or rectangular), cylindrical, spherical, and conical shapes, and may be custom-made according to the user's requirements. Depending on the shape of the housing (110), the diffusion direction and range of the fire extinguishing agent may be controlled.

[0029] FIG. 3 is a cross-sectional view of a fire keeper according to one embodiment. In the following description, parts that overlap with the description of FIG. 1 and FIG. 2 will be omitted. Referring to FIG. 3, the fire keeper (100) may include a housing (110) composed of a housing body (111) and an discharge part (112), and a first space (120) and a second space (130).

[0030] When a fire occurs, including a wildfire, the ambient temperature rises to approximately 200~300℃ or higher, the smoke temperature in the adjacent area rises to approximately 600℃ or higher, and the temperature at the center of the fire can rise up to 1,100℃. When the ambient temperature of the fire keeper (100) rises to a certain temperature, cracks may occur in the housing (110).

[0031] The shape of the housing (110) can be box-shaped (cuboid or rectangular), cylindrical, spherical, conical, etc., and depending on the shape of the housing (110), the diffusion direction and diffusion range of the fire extinguishing agent filled in the first space (120) can be controlled. For example, in the case of a spherical housing (110), all surfaces are uniform, so the fire extinguishing agent can be discharged uniformly. In the case of a conical housing (110), the material is concentrated at a narrow end, so the fire extinguishing agent can be discharged in a point shape. In the case of a cuboid housing (110), the fire extinguishing agent can be discharged evenly in the direction where the surface exists. Therefore, the shape and size of the housing (110) can be selected by considering the installation location, diffusion direction, and diffusion range.

[0032] In the present embodiment, the housing (110) may include a housing body (111) and a discharge part (112) provided in either the housing body (111) to discharge a fire extinguishing agent. In the above-described embodiment, the occurrence of a crack in the housing (110) may include a crack occurring in the discharge part (112) so that the fire extinguishing agent is discharged through the discharge part (112). In the present embodiment, the material of the housing (110) may be applied differently so that the discharge part (112) cracks faster than the housing body (111) at the same temperature.

[0033] In this embodiment, the housing (110) may be composed of one layer, two layers, or multiple layers. The more layers it is composed of, the higher the heat resistance of the fire keeper (100). In this embodiment, when the housing (110) is composed of a first layer and a second layer, the first layer may be made of a first material, and the second layer may be made of a second material and located on top of the first layer. Here, the first material may include at least one of a material composed of polyamide, polyimide, polyetheretherketone, polypropylene, polylactic acid, polycarbonate, and glass wool. Additionally, the second material may include one of a material composed of a thermosetting material, a glass fiber material, and a thermoreactive material.

[0034] In the present embodiment, when the housing (110) is composed of a first layer and a second layer, the housing body (111) is composed of a first layer and a second layer, and the discharge portion (112) may be composed of either the first layer or the second layer. With such a configuration, the discharge portion (112) may crack faster than the housing body (111) at the same temperature.

[0035] In this embodiment, the first space (120) may be filled with a fire extinguishing agent. The fire extinguishing agent may be composed of a composite material comprising water, a fire retardant, and other performance agents. The fire extinguishing agent may be composed of a material in granular or liquid form. In this embodiment, the fire retardant may include at least one of a material composed of ammonium polyphosphate, diammonium phosphate, ammonium sulfate, urea, potassium bicarbonate, potassium carbonate, potassium acetate, sodium carbonate, trisodium phosphate, and potassium acetate. In this embodiment, the other performance agent may include at least one of a material composed of hydropropylpolymer, loess, monoethylene glycol, and polypropylene glycol.

[0036] In this embodiment, the second space (130) may be filled with a non-combustible agent. The non-combustible agent is a non-combustible gas or non-combustible liquid that expands above a set temperature, and as the fire extinguishing agent moves due to the expansion or vaporization of the non-combustible agent and pressurizes the housing (110), cracks may occur in the housing (110).

[0037] In this embodiment, the second space (130) may be provided in a space opposite to the discharge section (112) within the housing (110). Additionally, the second space (130) may be provided in a space facing the facility (200) within the housing (110). Thus, the first space (120) may be provided between the second space (130) and the discharge section (112) within the housing (110).

[0038] FIG. 4 is an example diagram of the range of fire extinguishing agent discharge of a fire keeper according to one embodiment. In the following description, parts that overlap with the description of FIG. 1 to FIG. 3 will be omitted. Referring to FIG. 4, four fire keepers (100) are installed around a facility (200) that is a tree. Two of these fire keepers (100) are activated and fire extinguishing agents are discharged. The discharged fire extinguishing agents are discharged in a manner that surrounds the tree, which can help prevent fire from approaching the tree or help cool down the tree that is already on fire and suppress the fire. In this embodiment, the range of fire extinguishing agent discharge may vary depending on the shape and size of the housing (110).

[0039] FIG. 5 is a schematic diagram of the installation of a fire keeper according to another embodiment. In the following description, parts that overlap with the descriptions of FIG. 1 to 4 will be omitted. Referring to FIG. 5, FIG. 5 (a) illustrates a fire keeper (100) installed on a tree in a forest where a wildfire has occurred, spraying a fire extinguishing agent in response to the fire. FIG. 5 (b) illustrates a fire keeper (100) installed on a street light in a residential area where a fire has occurred, spraying a fire extinguishing agent in response to the fire. FIG. 5 (c) illustrates the placement of fire keepers in the overall regional environment. It illustrates that multiple fire keepers (100) are installed on trees and street lights in the vicinity of residential areas, cultural properties, and major facilities, and are prepared to discharge a fire extinguishing agent within a range capable of protecting the surrounding area in the event of a fire.

[0040] The fire keeper (100) according to the present embodiment can play an important role in fire prevention and response not only in forest areas but also in urban areas. When the fire keeper (100) is installed in an appropriate location to suit various terrains and environments, it can effectively protect houses, cultural properties, and major facilities from fire.
