The auxiliary ventilation assembly includes an auxiliary ventilation net 5, a first rotating rod 51, and a winding roller 52; the first rotating rod 51 is rotatably mounted on the ventilation net box 12. One end of the first rotating rod 51 is connected to the take-up roller 52, on which an auxiliary ventilation net 5 is installed. A first gear 42 is installed on the first rotating rod 51. By setting the auxiliary ventilation net 5, when the motor 9 starts, it drives the second rotating rod 7 to rotate. When the second rotating rod 7 rotates, it drives the second gear 62 to rotate.

When the second gear 62 rotates, it drives the second rack 6 to descend. When the second rack 6 descends, it drives the protective box 2 to descend. At this time, the main extrusion block 21 descends away from the auxiliary extrusion block 3, the spring 35 returns to its original position, and drives the protective top plate 32 to move and open the support frame 1. When the protective top plate 32 moves, it drives the first rack 4 to move, which in turn drives the first gear 42 to rotate. When the first gear 42 rotates, it drives the first rotating rod 51 to rotate. When the first rotating rod 51 rotates, it drives the take-up roller 52 to rotate. At this time, the protective box 2 moves, pulling the auxiliary ventilated net 5 to move. With the rotation of the take-up roller 52, the auxiliary ventilated net 5 is moved out of the ventilated net box 12.
[0023] In summary, in this embodiment, the outdoor high-voltage drop-out fuse protection device according to this embodiment, by setting the support frame 1, can easily support the fuse body 13; by setting the ventilated mesh box 12, can easily store the auxiliary ventilated mesh 5; by setting the bottom rod 22, can easily support the main extrusion block 21; by setting the guide ring 36 and the guide rod 33 in a sliding connection, can easily guide and limit the protective top plate 32; by setting the third connecting rod 37, can easily support the protective top plate 32; by setting the second connecting rod 31, can easily support the auxiliary extrusion block 3; by setting the second support rod 92 and the support frame 91 in cooperation, can easily support the motor 9; and by setting the connecting block 72, can easily...

The sliding ring 81, slidably connected to the sliding rod 8, facilitates guiding and limiting the protective box 2. The side rod 82 also facilitates support for the protective box 2. A motor 9 is installed; when it starts, it drives the second rotating rod 7 to rotate. When the second rotating rod 7 rotates, it drives the second gear 62 to rotate. When the second gear 62 rotates, it facilitates the upward movement of the second rack 6. When the second rack 6 rises, it facilitates the upward movement of the protective box 2. When the protective box 2 rises, it facilitates the upward movement of the bottom rod 22 and the main extrusion block 21. When the main extrusion block 21 connects with the auxiliary extrusion block 3... Upon contact, the protective box 2 continues to rise, and the main extrusion block 21 can extrude the auxiliary extrusion block 3. At this time, the guide ring 36 slides on the guide rod 33, the spring 35 extends, and thus drives the protective top plate 32 to move, thereby closing the support frame 1. At this time, the protective box 2 can shield the front and sides of the support frame 1, which can facilitate rain protection for the front and sides of the fuse body 13. At this time, the protective top plate 32 shields the top of the support frame 1, which can facilitate rain protection for the top of the fuse body 13.

The internal structure of the fuse body 13 is designed to prevent damage. The first support rod 41 facilitates support for the first rack 4. The auxiliary vent mesh 5 allows the motor 9 to start, driving the second rotating rod 7 to rotate. This rotation of the second rotating rod 7 drives the second gear 62 to rotate, which in turn drives the second rack 6 to descend. This descent of the second rack 6 facilitates the descent of the protective box 2. At this point, the main pressing block 21 descends away from the auxiliary pressing block 3, and the spring 35 returns to its original position, causing the protective top plate 32 to move and open the support frame 1. The movement of the protective top plate 32 moves the first rack 4, which in turn drives the first gear 42 to rotate. The rotation of the first gear 42 then drives the first rotating rod 51 to rotate.When the first rotating rod 51 rotates, it drives the take-up roller 52 to rotate. At this time, the protective box 2 moves, which can pull the auxiliary ventilated net 5 to move. With the rotation of the take-up roller 52, the auxiliary ventilated net 5 can be moved out of the ventilated net box 12. By setting the auxiliary ventilated net 5, it is convenient to provide ventilation protection on both sides of the fuse body 13, making the fuse body 13 less susceptible to collision damage. By setting the main ventilated net 14, it is convenient to provide ventilation protection on the top and front of the fuse body 13, making the fuse body 13 less susceptible to collision damage. The fuse body 13 has an inspection port, which allows the staff to use the inspection rod to pull and close the fuse body 13. When the protective box 2 and the protective top plate 32 move to close the support frame 1, it is convenient to roll up and store the auxiliary ventilated net 5.
