A through groove 906 is opened at the top end of the inner cylinder 903, and the through groove 906 is connected to the inner cavity of the inner cylinder 903. When the inner cylinder 903 rotates to the side where the through groove 906 is close to the heat dissipation holes 902, external air can enter the inner side of the bridge through the connecting pipe 904 and the heat dissipation holes 902, facilitating heat dissipation. When the inner cylinder 903 rotates to the side where the through groove 906 is away from the heat dissipation holes 902, the heat dissipation holes 902 are closed to block the air and prevent moist air and rainwater from entering the bridge to protect the cables.

[0027] The cable lifting module includes first fixing plates 2 fixedly installed at equal intervals on the inner side of the chassis 1. Both ends of the first fixing plates 2 are fixedly connected to the two side walls of the chassis 1 respectively. First placement grooves 3 are opened at equal intervals at the top ends of the first fixing plates 2. Second fixing plates 5 are installed at equal intervals at the bottom end of the top cover 4. The second fixing plates 5 are located above the first fixing plates 2. Second placement grooves 6 are opened at equal intervals at the bottom ends of the second fixing plates 5. The first placement grooves 3 and the second placement grooves 6 form a cable limiting groove. Card slots 7 are opened at equal intervals on the two side walls of the chassis 1. The two card slots 7 on both sides correspond to each other, and the corresponding two card slots 7 are symmetrically arranged on both sides of the second fixing plate 5.

[0028] The clamping and fixing module 8 includes movable grooves 801 symmetrically opened inside the second fixing plate �. The top ends of the movable grooves 801 penetrate through to the top end of the top cover 4. Rod grooves 802 are opened at one ends of the two movable grooves 801 away from each other. Movable plates 803 are slidably installed inside the movable grooves 801. A clamping rod 804 is fixedly installed on one side of the movable plate 803 close to the rod groove 802.

During installation, the clamping rods 804 at both ends of the second fixing plate 5 are inserted into the card slots 7, which is convenient for clamping and fixing the chassis 1 and the top cover 4.

[0029] Working principle: During installation, first install the cables in the first placement groove 3 on the first fixing plate 2 in sequence, then install the top cover 4 on the top of the base frame 1, so that the second fixing plate 5 on the top of the top cover 4 corresponds to the first fixing plate 2 one by one, and the first placement groove 3 and the second placement groove 6 form a cable limiting groove to limit the cable, which is convenient for cable installation;

[0030] When installing the base frame 1 and the top cover 4, the two connecting plates 806 above the top cover 4 are pushed closer to each other, so that the clamping rod 804 enters the rod groove 802. After the second fixing plate 5 and the first fixing plate 2 are assembled, the connecting plates 806 are loosened, so that the clamping rod 804 moves outward under the elastic force of the spring 805, so that the clamping rod 804 is clamped into the inside of the clamping groove 7, thereby clamping and fixing the base frame 1 and the top cover 4, making installation convenient;

[0031] When heat dissipation is required, the inner cylinder 903 is rotated by the motor 905 to the position corresponding to the through slot 906 and the heat dissipation hole 902, and the outside air can enter the inside of the bridge through the connecting pipe 904 and the heat dissipation hole 902 to dissipate heat. When the external environment is rainy or the air is relatively humid, the inner cylinder 903 is rotated by the motor 905 to the state where the through slot 906 and the heat dissipation hole 902 are separated, and the heat dissipation hole 902 is closed, so that the outside air will not enter the inside of the bridge, thereby protecting the cable.
