Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a DC power distribution device for communication, including a communication power supply box 1. A protective door 4 is rotatably connected to the front end of the communication power supply box 1 via a hinge. An air pump 3 is fixedly connected to the upper end of the communication power supply box 1, and an air pipe 2 is fixedly connected to the air pump 3's suction end. A smoke sensor 16 is fixedly connected to the rear inner wall of the communication power supply box 1. A tapered tube 6 is fixedly connected between the air pipe 2 and the communication power supply box 1. A vent 5 is provided at the right end of the communication power supply box 1, and a support frame 11 is fixedly connected to the right inner wall of the communication power supply box 1. A door 10 is rotatably connected to the inside of the device via a hinge. A pull rope 8 is fixedly connected to the upper right end of the door 10, and a suction plate 7 is fixedly connected to the right end of the pull rope 8. A limit ring 9 is fixedly connected inside the tapered tube 6, and the suction plate 7 is slidably connected inside the tapered tube 6. An air extraction hole 13 is provided on the right side of the door 10. This design solves the problems of the original device, which required manual water to be introduced into the water tank before use, and the fact that when a fire occurred inside the communication power supply box 1, the airbag needed time to collect the heat from the flames, which made it impossible to extinguish the smoke in time, causing the fire to grow larger and damaging the electronic components inside the communication power supply box 1.

[0021] As the first embodiment of this utility model: a traction rope 12 is fixedly connected to the upper end of the barrier door 10 on the right inner wall of the communication power supply box 1. The traction rope 12 and the pull rope 8 are made of fireproof cotton. By limiting the barrier door 10, it can prevent the barrier door 10 from damaging the electronic components inside the communication power supply box 1 after resetting. The traction rope 12 and the pull rope 8 are made of fireproof cotton, which can prevent the flame from burning through the pull rope 8 and the traction rope 12 when the flame spreads. The barrier door 10 and the tapered tube 6 are made of fireproof material, which can reduce the damage to the barrier door 10 and the tapered tube 6 when a fire occurs inside the communication power supply box 1, so that the barrier door 10 and the tapered tube 6 can be recycled. A magnetic frame 15 is fixedly connected to the front end of the communication power supply box 1. The magnetic frame 15 is attracted to the protective door 4. The magnetic frame 15 installed at the front end of the communication power supply box 1 attracts the protective door 4, which can increase the sealing effect between the communication power supply box 1 and the protective door 4, allowing the air pump 3 to completely extract the air from the communication power supply box 1. A fireproof layer is fixedly connected inside the communication power supply box 1. A fireproof and breathable shell is provided on the surface of the smoke sensor 16. The fireproof layer inside the communication power supply box 1 can prevent the flame inside the communication power supply box 1 from spreading to the outside. The fireproof and breathable shell on the surface of the smoke sensor 16 can detect the smoke inside the communication power supply box 1 while preventing the smoke sensor 16 from being burned. A protective pad 14 made of fireproof cotton is fixedly connected to the upper right end of the baffle door 10. The protective pad 14 installed on the baffle door 10 can reduce the impact and deformation of the baffle door 10 caused by the communication power supply box 1, thereby preventing the deformation of the baffle door 10 from affecting the fire extinguishing of the air pump 3.

[0022] As a second embodiment of this utility model: when the electronic components inside the communication power supply box 1 emit smoke, the smoke sensor 16 detects the smoke and controls the air pump 3 to draw air into the communication power supply box 1. The suction plate 7 moves to the right under the suction force of the air pump 3, and at the same time, the pull rope 8 drives the baffle 10 to fit into the communication power supply box 1, so that the communication power supply box 1 is sealed. The air pump 3 draws air from the communication power supply box 1 through the conical tube 6 and the air extraction hole 13, thereby reducing the oxygen in the communication power supply box 1 and preventing the electronic components inside the communication power supply box 1 from burning.
