DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Embodiment 1:
[0023] See also Figure 1-4 In this embodiment, a distribution box with a protective structure includes a distribution box body 1, a partition 2 is fixedly connected to the inside of the distribution box body 1, a sealing door 3 is hinged on the front of the distribution box body 1, and a fire protection mechanism is provided inside the distribution box body 1;
[0024] The fire protection mechanism includes a flame sensor 4 and a temperature sensor 5 which are respectively fixedly installed on the left and right sides of the inner wall of the distribution box body 1. A groove 6 is opened on the top of the partition 2, and a discharge pipe 7 is fixedly installed on the bottom of the partition 2. A carbon dioxide fire extinguishing agent storage tank 8 is placed inside the groove 6. A connecting pipe 9 is installed on the top of the carbon dioxide fire extinguishing agent storage tank 8. An electromagnetic container valve 10 is fixedly installed on the outer surface of the connecting pipe 9. A high-pressure hose 11 is fixedly installed at the front end of the connecting pipe 9. The high-pressure hose 11 is connected to the discharge pipe 7. A controller 12 and a buzzer alarm 13 are fixedly installed on the front of the sealing door 3. When a short circuit and fire occur inside the distribution box body 1, the temperature sensor 5 can detect changes in the internal temperature, and the infrared receiving tube inside the flame sensor 4 will receive the infrared rays emitted by the flame, and convert this signal into an electrical signal, which is transmitted to the controller 12.
[0025] At this time, the controller 12 will open the electromagnetic container valve 10 and start the buzzer alarm 13. When the electromagnetic container valve 10 is opened, the carbon dioxide fire extinguishing agent inside the carbon dioxide fire extinguishing agent storage tank 8 will be introduced into the discharge pipe 7 through the high-pressure hose 11 and finally discharged. At the same time, the volume of the carbon dioxide fire extinguishing agent will expand sharply and absorb a large amount of heat, thereby reducing the internal temperature of the distribution box body 1 and diluting the oxygen concentration to achieve the effect of suffocation and fire extinguishing.
[0026] In addition, the buzzer alarm 13 will sound an alarm to alert nearby staff, and compared with the existing distribution box, the fire inside the distribution box can be extinguished in time, thereby achieving the effect of preventing the fire from getting worse, and its safety is better.
[0027] Among them, the inner bottom wall of the distribution box body is fixedly connected with an equipment tray 14, and a rubber insulating pad 15 is arranged on the inner side of the equipment tray 14 to prevent leakage. By arranging the equipment tray 14 and the rubber insulating pad 15, it can play an insulating effect when leakage occurs in the electrical equipment, thereby preventing the current from affecting the cable through the distribution box body 1.
[0028] Among them, a door handle is welded on the front of the sealed door 3, a heat dissipation hole 16 is opened on the front of the sealed door 3, the controller 12 is electrically connected to the flame sensor 4, the temperature sensor 5, the electromagnetic container valve 10 and the buzzer alarm 13, and the number of carbon dioxide fire extinguishing agent storage tanks 8 is two. By setting the heat dissipation holes 16, the effect of ventilation and heat dissipation is achieved.
[0029] It should be noted that the left and right sides of the distribution box body 1 are fixedly connected with mounting frames 17, and through holes 18 are opened on the left and right sides of the mounting frame 17. Threaded columns 19 are arranged inside the through holes 18. The outer surface of the threaded column 19 is fixedly connected with a butt plate 20. The outer surface of the threaded column 19 is threadedly sleeved with a fixing nut 21, and the side of the fixing nut 21 is pressed against the side of the mounting frame 17. By arranging the mounting frame 17, the threaded column 19 and the butt plate 20, the butt plate 20 can be pressed against the ground, thereby enhancing the stability of the distribution box body 1 and reducing the probability of tipping over.
[0030] Among them, when it is necessary to place the distribution box body 1 side by side, the staff can release the fixing nut 21 to limit the threaded column 19, and then place the abutment 20 vertically to avoid the abutment 20 occupying too much space. After the vertical placement is completed, re-tighten the fixing nut 21 to re-limit the threaded column 19 and the abutment 20.
[0031] Embodiment 2:
[0032] See also Figure 1On the basis of the first embodiment, the distribution box body 1 is in the shape of a rectangular parallelepiped, and pads are fixedly connected around the bottom of the distribution box body 1. By setting the pads, the effect of padding the bottom is achieved, thereby preventing the bottom of the distribution box body 1 from directly contacting the ground.
[0033] In the distribution box with a protective structure, when a short circuit and fire occur inside the distribution box body 1, the temperature sensor 5 can detect the change of the internal temperature, and the infrared receiving tube inside the flame sensor 4 will receive the infrared rays emitted by the flame, and convert this signal into an electrical signal, and transmit it to the controller 12. At this time, the controller 12 will open the electromagnetic container valve 10 and start the buzzer alarm 13. When the electromagnetic container valve 10 is opened, the carbon dioxide fire extinguishing agent inside the carbon dioxide fire extinguishing agent storage tank 8 will be introduced into the discharge pipe 7 through the high-pressure hose 11, and finally discharged. At the same time, the volume of the carbon dioxide fire extinguishing agent will expand sharply and absorb a large amount of heat, thereby reducing the internal temperature of the distribution box body 1 and diluting the oxygen concentration to achieve the effect of suffocation and extinguishing the fire. In addition, the buzzer alarm 13 will sound an alarm to remind nearby staff, and compared with the existing distribution box, the internal fire of the distribution box can be extinguished in time, thereby achieving the effect of avoiding the aggravation of the fire, and its safety is better.
