Description

Technical Field

[0001] The utility model relates to the field of fire-fighting facilities, in particular to a fixed fire-fighting device. Background Art

[0002] In China, with the continuous advancement of informatization, the number and scale of IDC (independent data center) rooms are rapidly increasing, and fire safety requirements are becoming increasingly stringent. Traditional fire protection systems are no longer able to meet the needs of IDC rooms for comprehensive, intelligent, and networked fire safety monitoring and management. To address this, various IDC room fire safety detection and control devices and systems have emerged. These systems use IoT sensors to collect real-time status data on key equipment and components within the IDC room, including temperature, humidity, and smoke concentration. Smoke concentration is typically detected using smoke sensors. Smoke sensors are important safety devices that can sensitively detect smoke concentration in the air. Utilizing principles such as the photoelectric effect or the ionization effect, they quickly trigger an alarm when smoke is detected, alerting personnel to the risk of fire.

[0003] During the detection process, indoor smoke will enter the smoke sensor through the air inlet. The air inlet of the smoke sensor varies in size. In actual use, smaller insects can easily enter the smoke sensor through the larger air inlet and damage the internal components. When the air inlet is small, fine impurities can easily clog the air inlet. Therefore, a fixed fire-fighting device is proposed. Utility Model Content

One end of the pressure spring is fixed on the pressure cap, and the other end of the pressure spring is connected to the cleaning frame.
