The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0019] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0020] Example: Refer to Figure 1-3 , a fireproof structure of a rail transit bidirectional converter, comprising a cabinet 1, a rail transit bidirectional converter 2 is mounted on the lower wall of the cabinet 1, a delivery box 3 is embedded in the upper wall of the cabinet 1, and plug rods 4 are movably inserted on the two side walls of the delivery box 3, and two electric push rods 5 are respectively mounted on the two side walls of the delivery box 3, and two connecting rods 6 are connected between the telescopic ends of the two electric push rods 5 and the two plug rods 4, and rubber clamps 7 are respectively mounted on the opposite walls of the two plug rods 4, and a fire extinguishing ball 8 is clamped between the two rubber clamps 7; fans 9 are respectively embedded in the two side walls of the cabinet 1; filters 10 are respectively mounted in the two side walls of the cabinet 1 and on both sides of each fan 9; a smoke alarm 11 is mounted on the upper wall of the cabinet 1 and on one side of the delivery box 3; air intake pipes 12 are respectively embedded in the upper wall of the cabinet 1 and on both sides of the delivery box 3, and an electric valve 13 is respectively mounted on each air intake pipe 12; a warning light 14 is mounted on the upper wall of the delivery box 3;

[0021] The specific working principle is as follows:

[0022] During normal use, one of the fans 9 installed on the cabinet 1 rotates forward to draw external air into the cabinet 1, and the other fan 9 rotates forward to draw air in the cabinet 1 for exhaust, thereby accelerating the air flow rate in the cabinet 1 and improving the heat dissipation efficiency during daily use. When the smoke alarm 11 installed in the cabinet 1 senses that the smoke concentration in the cabinet 1 exceeds the set value, it sends a signal, and the main control installed thereon receives the signal, processes it and sends a control command, the fan 9 stops running, and the warning light 14 installed on the delivery box 3 lights up to warn, so that the staff can find the fire cabinet 1 in time. At the same time, the telescopic end of the electric push rod 5 installed on the delivery box 3 drives the connecting rod 6 to move horizontally, so that the insertion rod 4 moves to both sides , the rubber clamp 7 no longer clamps the fire extinguishing ball 8, the fire extinguishing ball 8 falls into the cabinet 1 and is roasted by the open flame, the fire extinguishing ball 8 is broken, and the dry powder in the fire extinguishing ball 8 splashes out, and the cabinet 1 is extinguished. After the fire is extinguished, wait for the staff to arrive. After the staff arrives, control the operation through the main control, and the electric valve 13 installed on the air intake pipe 12 is opened. One fan 9 rotates in the opposite direction and the other fan 9 rotates forward to extract the air in the cabinet 1 to accelerate the air flow rate, and the air is discharged through the filter 10 to filter the dry powder floating in the cabinet 1, so that the floating dry powder adheres to the filter 10, which is convenient for the staff to open the cabinet 1 to replace and repair the internal rail transit bidirectional converter 2.
