Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting devices, in particular to a fire fighting device for a server chassis. Background Art

[0002] A server chassis is a shell used to store and protect the hardware components of a server. It is a large metal or plastic box, mostly with removable side panels, front panels and rear panels. Its interior is mainly used for convenient installation and maintenance of designed hardware components. These hardware components will generate a lot of heat when working, causing the temperature inside the cabinet to be too high, which can easily lead to fire inside the memory.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN211481837U proposes a network chassis with good safety performance. The device detects the fire signal through the smoke sensor and feeds the signal back to the controller. The controller controls the solenoid valve to open, so that the carbon dioxide or dry powder in the fire extinguisher is sprayed into the interior of the box, thereby extinguishing the fire and preventing the fire from spreading.

[0004] However, although the above-mentioned network chassis with good safety performance can sense fire through the smoke sensor and use the controller to make the fire extinguisher to extinguish the fire inside the chassis, when the fire extinguisher of the network chassis with good safety performance extinguishes the fire inside the chassis through the fire extinguishing pipe, the air inlet and outlet holes opened on the chassis will continue to provide air to the inside of the chassis, which will cause the fire source inside the chassis to continue to burn, resulting in a decrease in the fire extinguishing efficiency of the device. Therefore, the utility model provides a fire fighting device for a server chassis to meet the demand. Utility Model Content

[0036] Working principle:

[0037] When a fire occurs inside the box 1, the smoke sensor 13 and the temperature sensor 14 inside the box 1 will sense and send a signal to the controller 19, so that the controller 19 controls the motor 61 to rotate, the motor 61 drives the threaded rod 62 to rotate, the threaded rod 62 drives the movable block 63 to move, thereby driving the baffle 22 to move along the movable groove 18 and sealing the ventilation hole 15 to isolate the outside air from entering the box 1.

The gas in the fire extinguisher 11 is sprayed into the box body 1 along the injection pipe 20 through the through pipe 5, thereby extinguishing the fire source in the box body 1. While extinguishing the fire through the fire extinguisher 11 and the injection pipe 20, the device isolates the box body 1 from the outside through the baffle 22, thereby preventing external air from entering the box body 1, isolating the necessary conditions for the fire source to burn, accelerating the efficiency of fire extinguishing, and ensuring the safety of the inside of the box body 1. It solves the problem that when a fire occurs inside the existing server chassis, the air inlet and air outlet holes opened on the box body 1 will continue to provide air to the inside of the box body 1, which makes the fire source inside the box body 1 continue to burn, resulting in reduced fire extinguishing efficiency of the device.
