Wherein, the longitudinal section of box 14 that goes out fires is the cambered surface to can make box 14 that goes out fires arrange around cable joint 4, in order to improve box 14's that goes out fires extinguishing efficiency.
A plurality of spray holes 16 are spaced apart at the bottom of the fire box 14, and each spray hole 16 is arranged toward the cable connector 4.
The fire extinguishing medium 15 is arranged in the fire extinguishing box 14, and under the condition that the cable joint 4 is in a fire, the fire extinguishing medium 15 can be sprayed to the cable joint 4 through the spray holes 16 at the bottom of the fire extinguishing box 14, so that the cable joint 4 is extinguished, and the fire is prevented from spreading.
Preferably, the fire extinguishing medium 15 is liquid at normal temperature and is easily vaporized by heat, for example, the fire extinguishing medium 15 may be perfluorohexanone.
The sealing films 17 are correspondingly arranged in the plurality of spray holes 16 one by one, and are used for blocking the spray holes 16 under the condition that no fire breaks out in the joint box 1, so that the fire extinguishing medium 15 in the fire extinguishing box 14 is prevented from flowing out.
In some of these embodiments, in case of a fire in the cable joint 4 inside the closure 1, the temperature inside the closure 1 rises at this time, the fire extinguishing medium 15 inside the fire extinguishing box 14 is gasified, resulting in an increase in pressure inside the fire extinguishing box 14, and the fire extinguishing medium 15 breaks through the sealing membrane 17 in case the pressure difference between the inside of the fire extinguishing box 14 and the outside of the fire extinguishing box 14 reaches a pressure threshold, thereby extinguishing the cable joint 4.
In some of these embodiments, in case the sealing membrane 17 is breached by the extinguishing medium 15 inside the extinguishing chamber 14, the staff may replace the sealing membrane 17 after adding the extinguishing medium 15.
The pressurization pipeline 20 is arranged on the side wall of the fire extinguishing box 14, communicated with the interior of the fire extinguishing box 14 and hermetically connected with one end of the electromagnetic valve 8. In case of fire in the cable joint 4 and the pressure inside the fire extinguishing box 14 is not sufficient to break through the sealing membrane 17, the pressure inside the fire extinguishing box 14 is increased by the pressure increasing pipe 20, avoiding that the fire extinguishing medium 15 inside the fire extinguishing box 14 cannot be sprayed to the cable joint 4 through the spray holes 16 in case of insufficient pressure inside the fire extinguishing box 14.
Wherein, solenoid valve 8 is used for sealed pressure boost pipeline 20, avoids the inside fire extinguishing medium 15 of box 14 of putting out a fire to flow out to the box 14 outside of putting out a fire through pressure boost pipeline 20.
Further, in order to facilitate the addition of the fire extinguishing medium 15 to the interior of the fire extinguishing box 14, the fire extinguishing unit 6 further comprises liquid filling screw holes 18 and sealing screws 19.
The liquid injection screw hole 18 is disposed on a side wall of the fire extinguishing box 14 and communicated with the inside of the fire extinguishing box 14. In case of shortage of the fire extinguishing medium 15 inside the fire extinguishing box 14, the worker can add the fire extinguishing medium 15 into the fire extinguishing box 14 through the liquid filling screw hole 18.
The sealing screw 19 is arranged in the liquid injection screw hole 18 and is used for sealing the liquid injection screw hole 18 and preventing the fire extinguishing medium 15 from flowing out through the liquid injection screw hole 18.
The pressurizing unit 7 is detachably arranged on the inner side wall of the joint box 1 and is communicated with the fire extinguishing unit 6. The pressurizing unit 7 is used for increasing the pressure inside the fire extinguishing box 14 in case of fire in the cable joint 4 and insufficient pressure inside the fire extinguishing box 14, so that the fire extinguishing medium 15 inside the fire extinguishing box 14 is sprayed to the cable joint 4 through the spray holes 16.
Wherein, the pressurizing unit 7 comprises a pressurizing bottle 21 and an air outlet pipeline 22.
The pressurizing bottle 21 is detachably arranged on the inner side wall of the joint box 1, and high-pressure inert gas is arranged in the pressurizing bottle. Such as a pressurized bottle 21, may be attached to the inside wall of the joint box 1 by screws.

In some of the embodiments, in the case that the worker detects that the electromagnetic valve 8 is opened, the worker may detach the pressure-increasing bottle 21 from the inner sidewall of the joint box 1 and then separate the air outlet pipe 22 from the electromagnetic valve 8, so that the worker may add the inert gas to the inside of the pressure-increasing bottle 21 through the air outlet pipe 22.
Wherein, because one end of the solenoid valve 8 is connected with the pressure increasing pipeline 20 on the fire extinguishing box 14 in a sealing manner, under the condition that the solenoid valve 8 is opened, the pressure increasing bottle 21 is communicated with the fire extinguishing box 14 through the air outlet pipeline 22 and the pressure increasing pipeline 20, so as to increase the pressure inside the fire extinguishing box 14, and the fire extinguishing medium 15 inside the fire extinguishing box 14 is sprayed to the cable joint 4 through the spray holes 16.
In some of these embodiments, in case of a fire not occurring inside the closure 1, the solenoid valve 8 may be closed to prevent the high-pressure gas inside the booster cylinder 21 from flowing inside the fire extinguishing box 14, causing the fire extinguishing medium 15 inside the fire extinguishing box 14 to spray towards the cable connector 4.
Specifically, in case of a fire at the cable joint 4, the electromagnetic valve 8 is opened at this time, and then the pressure boosting bottle 21 is communicated with the fire extinguishing box 14 through the air outlet pipe 22 and the pressure boosting pipe 20, so as to increase the pressure inside the fire extinguishing box 14, and the fire extinguishing box 14 sprays the fire extinguishing medium 15 to the cable joint 4; with the electromagnetic valve 8 closed, the booster cylinder 21 is not communicated with the fire extinguishing box 14, so that the fire extinguishing medium 15 inside the fire extinguishing box 14 can be maintained inside the fire extinguishing box 14.
The high-pressure gas may be a high-pressure inert gas, such as helium, or may be nitrogen.
