The present invention relates to a high-rise building fire monitoring and suppression system. More specifically, in the event of a high-rise building fire, one or more drone devices that spray fire extinguishing liquid are flown to prevent the spread of combustion in the upper floors of the building through early extinguishment and rapid response to the high-rise building fire. It is about a fire monitoring and suppression system for high-rise buildings that can be prevented in advance.

The number of high-rise buildings in Korea has been steadily increasing from 2010 to 2018, and at the same time, the number of fires in high-rise buildings is increasing, exceeding 100 cases per year.

Most high-rise buildings built in Korea use exterior materials using the drybeat method or aluminum composite panels. Since both exterior materials are combustible exterior materials, combustion spreads quickly, and they cannot withstand the resulting load, causing a collapse process and secondary damage.

In recent high-rise buildings, gaps are likely to form near the end of the floor plate and the contact point between the exterior wall surface in the curtain wall construction of the exterior walls. These gaps are a fire protection weakness and the flame spreads to the upper floors of the combustion path, causing fire suppression to fail. There is a problem.

Due to the nature of high-rise buildings, it is difficult to reach the accident site (ignition point), so the golden time can be exceeded, and a lot of property and human damage can occur due to limitations in fire-fighting rescue activities.

The fire extinguishing charcoal of the present invention may have a charcoal shape extending in a certain length direction, and this fire briquette may be composed of a rigid body, a body, and a fire extinguishing agent.

It is also possible to have gunpowder built into the rear end of the projectile to provide propulsion during launch or to explode the body (in this case, it is possible to store the gunpowder to provide propulsion and the gunpowder to explode the body separately).

After these fire extinguishers are launched, they can approach the area where the fire occurs by destroying obstacles (e.g., glass windows, etc.) using a rigid body, and the shock transmitted from the rigid body is transmitted to the body to release the extinguishing agent inside the body (e.g. For example, it can mean the action of spreading the fire extinguishing agent by exploding the body. At this time, because there is a distance difference between the obstacle and the fire occurrence area, the body does not explode immediately after receiving the impact from the rigid body, but rather explodes several seconds (preferably 3 to 5 seconds) after the impact of the rigid body, exploding the fire extinguishing agent inside. It is desirable to design it to be released. For this purpose, the fire extinguisher is equipped with a timer and an impact detection sensor, so that the timer checks the preset time after the shock detection sensor detects the impact, and explodes the body when the time expires. In this way, the fire extinguisher is fired with a time difference. Since exploding an explosive is the same as the principle of a well-known bomb, a separate detailed explanation will be omitted.

The rigid body is located at the tip of the fire extinguisher and may have a cone shape made of metal. At this time, since the rigid body is the first to reach the object when the fire extinguisher is launched, it is desirable to use a metal that has sufficient strength to destroy glass, wooden boards, etc. in order to approach the fire outbreak area. Additionally, the metal may be a single metal such as aluminum, steel, or copper, an alloy, or a lamination of multiple types of metals.

The body is connected to the bottom of the rigid body and has a cylindrical shape including a receiving space therein. In detail, it has a cylindrical shape with an accommodating space inside, but the surface facing the rigid body may be closed or may have a cover that can be opened and closed when necessary. At this time, the body releases the internal fire extinguishing agent by being destroyed by an impact received from a rigid body or by the explosion of separately built-in gunpowder. Therefore, it safely accommodates the internal fire extinguishing agent in normal times, but it is desirable to have enough strength to be destroyed in the event of a strong impact. And, for example, the body may be a carbon pipe made of carbon material.

The extinguishing agent may be accommodated in the accommodation space of the body, and serves to suppress the fire using effects such as cooling the fire or blocking air. At this time, the extinguishing agent may be a commercially available solid or liquid extinguishing agent and may include substances such as sodium bicarbonate, casein, and carbon dioxide.

In some embodiments, the main body 750 of the fire suppression drone 700 may further include a speaker unit 783. The speaker unit 783 may be disposed on the upper surface of the main body 750, but is not limited thereto.

In some embodiments, the speaker unit 783 may output a warning sound when a fire occurs and may output a warning of firing a fire extinguisher.

In some embodiments, the main body 750 may further include a light emitting unit 785, and the light emitting unit 785 may output a warning light source when a fire occurs.

As shown in FIG. 9 , in some embodiments, a plurality of light emitting units 785 may be disposed on the leg 770. Such a light emitting unit 785 may be a light emitting device such as LED or OLED. Through this light emitting unit 785, the movement of the fire suppression drone 700 can be visually clearly indicated to prevent collisions between people and the fire suppression drone 700, and at the same time, the fire suppression drone 700 can be extinguished. You can clearly see where the powder will be sprayed.

In some embodiments, a fire extinguishing powder box 789 may be disposed on the leg 770. For example, the fire extinguishing powder box 789 may be placed on the lower side of the leg in the direction in which the leg extends. In this fire extinguishing powder box 789, fire extinguishing powders such as sodium bicarbonate, casein, and carbon dioxide are placed, and in accordance with the fire extinguishing powder injection control signal from the flight control unit 250, the fire extinguishing powder box 789 is opened and the fire extinguishing powder is released. It is possible to spray downwards.

A temperature detection label (LA) may be placed on the outer surface of the fire extinguishing powder box 789. Thermosensitive labels (LA) are labels that use thermosensitive ink and have the characteristic of changing color depending on temperature. The thermal inks have a first discoloration range of 30°C to 40°C, a second discoloration range of 41°C to 70°C, and may have a third discoloration range when the temperature exceeds 70°C. For example, the thermosensitive label LA may display yellow in the first color change section, blue in the second color change section, and red in the third color change section.

If the third discoloration section continues, the shape of the fire extinguishing powder box 789 may be deformed and the opening of the fire extinguishing powder box 789 may malfunction, so this is to visually display the third discoloration section.

In some embodiments, the fire extinguishing powder box 789 may include an open/close line (OP). The opening/closing line (OP) is located at the bottom of the fire extinguishing powder box (789), and the fire extinguishing powder box (789) is opened through the opening/closing line (OP), and fire extinguishing powder is sprayed. If the fire extinguishing powder box 789 is deformed by heat, spraying through the opening/closing line (OP) may malfunction, so heat blocking members 787 may be disposed on both sides of the opening/closing line (OP). Specifically, the heat blocking members 787 are formed in a plurality of semicircular shapes, and may be alternately arranged on the left and right sides with respect to the opening and closing line (OP). For example, the heat blocking member 787 disposed on the right side may be spaced apart in the second direction (Y-axis direction), and the heat blocking member 787 disposed on the right side may be spaced apart in the second direction (Y-axis direction). It can be placed spaced apart. Additionally, the heat blocking members 787 may not overlap each other in the first direction (X-axis direction).

The heat blocking member 787 includes a plurality of heat blocking units arranged in a zigzag shape along the opening/closing line OP, and the plurality of heat blocking units may be formed in a semicircular shape.

The heat barrier member 787 may be a mixture of glass fire, phenolic resin, and calcium carbonate. For example, the heat barrier member 787 may include 75% by weight of glass fiber, 17% by weight of phenolic resin, and 8% by weight of calcium carbonate.

As such, the heat blocking member 787 prevents deformation of the opening and closing line (OP) of the fire extinguishing powder box 789.
