[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-7 The utility model discloses a distribution box capable of automatically extinguishing fire, comprising a box body 1, a distribution room 2 is arranged inside the box body 1, a mounting frame 11 is installed inside the distribution room 2, the mounting frame 11 is used to install components such as electric meters, instruments, and wires, and a fire detector is installed inside the distribution room 2 to detect whether a fire source is generated.

[0029] A control room 3 and a fire extinguishing room 4 are provided on one side of the distribution room 2. A fire extinguishing controller 12 is arranged inside the control room 3, and an aerosol automatic fire extinguishing device 7 is arranged inside the fire extinguishing room 4. The aerosol automatic fire extinguishing device 7 is a mature existing technology. For example, the QRR0.1G / SQ series automatic fire extinguishing device produced by Andun can be selected. The distribution room 2 and the fire extinguishing room 4 are connected by an aerosol connecting window 14. The connecting window 14 is evenly arrayed with connecting holes 17. When the aerosol automatic fire extinguishing device 7 is working, the sprayed aerosol fire extinguishing agent enters the distribution room 2 through the aerosol connecting window 14, and automatically fills the distribution room 2, surrounding the fire point to extinguish the fire.

[0030] The control room 3 and the fire extinguishing room 4 in the present application are arranged outside the distribution room 2, which has little impact on the internal structure of the existing distribution box and facilitates the transformation and application of the existing distribution box.

[0031] The fire detector includes a temperature sensor 10 and a smoke alarm 13 . The smoke alarm 13 is installed on the top of the power distribution room 2 . There are multiple temperature sensors 10 , which are distributed at intervals and stand on the inner wall of the power distribution room 2 .

[0032] The smoke alarm 13 is installed at the bottom of the inner top plate of the power distribution room 2, or the top of the side plate, and is used to detect the smoke generated when a fire occurs.

[0033] The temperature sensor 10 is used to detect the temperature of different areas in the distribution room 2. When a fire occurs, at the early stage of the fire, when the local temperature in the distribution room 2 changes, the temperature sensor 10 in the corresponding area can detect the temperature change, avoiding the situation where the temperature sensor is far away from the fire point and the temperature change can only be detected after the overall temperature in the distribution room 2 rises after a period of time after the fire occurs.

[0034] A UPS uninterruptible power supply 8 and a communication alarm module 9 are arranged inside the control room 3 . A signal antenna is arranged on the top of the communication alarm module 9 , and a signal wire is connected to the side wall of the control room 3 .

[0035] The communication alarm module 9 can select the TC35-4G alarm communication module. The distribution room 2, the control room 3 and the fire extinguishing room 4 are made of metal materials. The side wall of the control room 3 is used as a signal amplifier of the antenna of the communication alarm module 9 to reduce the signal weakening when the communication alarm module 9 is installed in the control room 3.

[0037] The top of the box body 1 is provided with an audible and visual alarm 15 and a spraying display light 16 , and the audible and visual alarm 15 and the spraying display light 16 are electrically connected to the fire extinguishing controller 12 .

[0038] When the fire detector detects a fire in the distribution room 2, it sends a signal to the fire extinguishing controller 12. The fire extinguishing controller 12 controls the aerosol automatic fire extinguishing device 7 to start the fire extinguishing, and at the same time starts the sound and light alarm 15 to alarm, prevent people from approaching, and pay attention to the danger.

[0039] A distribution room door 5 is arranged in front of the distribution room 2, and the distribution room door 5 is used alone with the distribution room 2 to facilitate the use of the distribution room 2 alone. A fire extinguishing room door 6 is arranged in front of the fire extinguishing room 4, and the fire extinguishing room door 6 covers the front of the control room 3 and the fire extinguishing room 4 at the same time.

[0040] The edges of the distribution room door 5 and the fire extinguishing room door 6 are installed with sealing strips. After closing the distribution room door 5 and the fire extinguishing room door 6, a connected enclosed space is formed in the distribution room 2 and the fire extinguishing room 4, reducing leakage when the aerosol fire extinguishing agent is sprayed.

[0041] The inner walls of the power distribution room 2 and the fire extinguishing room 4 are provided with fire retardant coatings to improve the fire resistance of the power distribution room 2 and the fire extinguishing room 4 and reduce the impact on the control room 3.

[0042] A heat insulation layer is provided on the inner wall of the control room 3 to reduce the high temperature impact on the UPS uninterruptible power supply 8, the communication alarm module 9 and the fire extinguishing controller 12 in the control room 3 in case of fire.

[0043] Working principle: When a fire occurs in the fire extinguishing chamber 2, the fire is detected by the temperature sensor 10 and the smoke alarm 13, and the communication alarm module 9 and the aerosol automatic fire extinguishing device 7 are simultaneously started through the fire extinguishing controller 12. The aerosol automatic fire extinguishing device 7 sprays an aerosol fire extinguishing agent, and the aerosol fire extinguishing agent automatically passes through the aerosol connecting window 14 into the fire extinguishing chamber 2 due to the pressure difference, fills the fire extinguishing chamber 2, surrounds the fire point and extinguishes the fire.
