Abstract

The present invention relates to an automatic fire extinguishing device for fire suppression and an automatic fire extinguishing system including the same, and more specifically, to an automatic fire extinguishing device including a remaining life monitoring function and an automatic fire extinguishing system applying the same. The automatic fire extinguishing device according to the present invention includes a structure capable of measuring the pressure inside the housing in a sealed state, thereby enabling real-time monitoring of the remaining amount of fire extinguishing agent. This allows for diagnosing the remaining lifespan of the device and more accurately determining the replacement time. Furthermore, since the first housing and the second housing are formed with a structure that allows for the adjustment of the connection angle, the length and placement of the housing can be flexibly adjusted according to the size or shape of the electrical and electronic device, thereby providing the effect of improved ease of installation. In addition, since it can be installed without separate structural modifications or fixing members by utilizing the existing structure of the electrical and electronic device, costs can be reduced. In addition, the automatic fire extinguishing system according to the present invention includes a communication function that transmits internal pressure information measured by the automatic fire extinguishing device to a central control unit or a user terminal, thereby enabling remote monitoring and maintenance of the status of multiple devices. This improves system management efficiency and enhances the speed and reliability of fire prevention and response.

Description

Automatic Fire Suppression Apparatus and System Capable of Monitoring Remaining Lifespan The present invention relates to an automatic fire extinguishing device for fire suppression and an automatic fire extinguishing system including the same, and more specifically, to an automatic fire extinguishing device including a remaining life monitoring function and an automatic fire extinguishing system applying the same. With the recent advancement of fire prevention and suppression technologies, various types of compact automatic fire extinguishing devices are being developed. Representative automatic fire extinguishing devices include sprinkler systems, gas fire extinguishing systems, aerosol fire extinguishers, and tube-type fire extinguishers, each of which is used differently depending on the type of fire and the application environment. In particular, fire extinguishing devices used in small, enclosed spaces are designed with key elements such as autonomous operation that does not require a power supply and rapid fire detection capabilities. Tube-type fire extinguishers, which suppress fires by releasing the extinguishing agent filled inside when the tube ruptures upon heating above a certain temperature, are particularly effective for responding to fires in confined spaces. However, it is difficult to diagnose the remaining lifespan of conventional tube-type fire extinguishers or predict when they should be replaced. Since it is difficult to diagnose or predict in advance even when their service life has expired, there is a problem where the tube is not destroyed when a fire actually occurs, leading to a failure in fire suppression. This is because the pressure inside the tube containing the fire extinguishing agent can gradually decrease over time. For example, pressure may fluctuate as the internal agent expands or contracts due to changes in external temperature, or it may gradually decrease due to minute leaks or partial vaporization of the agent. This pressure drop is a phenomenon that can naturally occur even under normal operating conditions and is difficult to detect visually from the device. In particular, when internal pressure drops below a certain threshold, the housing may not rupture even if the external temperature rises rapidly upon the outbreak of a fire, preventing the release of fire extinguishing agents. This can lead to a serious problem of failure in initial fire suppression. This is a potential risk factor that could result in actual loss of life and property damage, rather than just a simple functional degradation. Therefore, a means to monitor these pressure changes in real time and determine whether the fire extinguishing device can operate normally is essential. If the internal pressure of the automatic fire extinguishing device can be constantly detected and the replacement timing accurately determined based on this, users can ensure the reliability of the device and prevent unexpected fire extinguishing failures in advance. Accordingly, there is an increasing need for automatic fire extinguishing devices and systems equipped with technical means to monitor remaining lifespan. Currently, Korean registered patent No. 10-2298097 discloses a fire extinguisher management system and Korean registered patent No. 10-2467365 discloses a battery storage box fire prevention system; however, there is no disclosure regarding an automatic fire extinguishing device that monitors remaining lifespan by detecting changes in internal pressure of a fire extinguishing agent, or an automatic fire extinguishing system including the same.
