[0017] (3) When the trough-type straight-through bridge frame 2 and the trough-type straight-through bridge frame 3 are moved and expanded, the U-shaped extension frame is driven to move out from the inside of the U-shaped inner groove and expand, thereby filling and sealing the gaps between the trough-type straight-through bridge frame 1 and the trough-type straight-through bridge frame 2, and the trough-type straight-through bridge frame 2 and the trough-type straight-through bridge frame 3, thereby effectively protecting the cables; when the trough-type straight-through bridge frame 2 and the trough-type straight-through bridge frame 3 are moved and expanded, the trough-type straight-through bridge frame 3 is driven to move the cover plate B by connecting the hook and the slot, and the movement of the cover plate B drives the extension cover plate to move, and at the same time, the slider B is moved inside the horizontal sliding slot B, so that the four extension cover plates and the two cover plates C are moved and expanded, thereby shielding and sealing the tops of the expanded trough-type straight-through bridge frame 1, the trough-type straight-through bridge frame 2 and the trough-type straight-through bridge frame 3;
