[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] To improve overall security, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a bus duct body 1, a storage box 2, a pull-out plate 3 and a limiting mechanism. The storage box 2 is arranged on the bus duct body 1, and the storage box 2 is connected to the bus duct body 1. The pull-out plate 3 is arranged in the storage box 2, and dry powder is placed on the surface of the pull-out plate 3. The limiting mechanism is used to move the dry powder on the surface of the pull-out plate 3 to the conductive copper sheet 4. When the bus duct body 1 is installed and fixed, the cover plate 5 is rotated by rotating the hinge 6 to move the dry powder toward the storage box 2. The dry powder can be directly dropped onto the surface of the pull-out plate 3. When an open flame appears on the conductive copper sheet 4 inside the bus duct body 1, the handle 9 is pulled to slide the slider 8 in the slide groove 7 to pull the pull-out plate 3 toward the outside of the storage box 2. As the pull-out plate 3 moves, the powder contact 11 comes into contact with the dry powder on the surface of the pull-out plate 3, thereby intercepting the dry powder. The dry powder can be directly dropped onto the conductive copper sheet 4, thereby extinguishing the open flame and improving the overall safety.
[0020] In order to facilitate the extinguishing of the open flame in the bus duct body 1, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper surface of the storage box 2 is provided with a feeding port, and a cover plate 5 is arranged outside the feeding port. The cover plate 5 is movably arranged by a hinge 6. The rotation of the hinge 6 drives the rotation of the cover plate 5, so that the staff can add new dry powder to the storage box 2. Slide grooves 7 are provided on both sides of the storage box 2, and sliders 8 adapted to the slide grooves 7 are provided on both sides of the pull-out plate 3. The sliders 8 can slide along the length direction of the slide grooves 7. The slides 8 slide in the slide grooves 7 to drive the movement of the pull-out plate 3. A fixed-point protrusion (not shown) is provided at the end of the slide groove 7 to prevent the pull-out plate 3 from derailing. A handle 9 is provided at one end of the pull-out plate 3 away from the storage box 2, and the handle 9 is used to facilitate pulling and pushing the pull-out plate 3. The limiting mechanism includes a limiting plate 10 disposed outside the storage box 2 and close to the pulling direction of the pull-out plate 3. The lower surface of the limiting plate 10 is provided with a powder-dumping contact 11. The powder-dumping contact 11 is provided in a plurality and arranged at equal intervals. When the pull-out plate 3 moves outward, the dry powder on the surface of the pull-out plate 3 is abutted by the powder-dumping contact 11, so that the dry powder is moved to the conductive copper sheet 4 to achieve the purpose of extinguishing the fire. The conductive copper sheet 4 is provided in a plurality and is provided in the busbar trunking body 1.
[0021] When in use, first, after the bus duct body 1 is installed and fixed, the cover plate 5 is rotated by rotating the hinge 6 to add dry powder toward the storage box 2, and the dry powder can directly fall on the surface of the pull-out plate 3. When an open flame appears on the conductive copper sheet 4 inside the bus duct body 1, pull the handle 9, and slide the slider 8 in the slide groove 7 to drive the pull-out plate 3 to be pulled toward the outside of the storage box 2. As the pull-out plate 3 moves, the powder contact 11 will contact the dry powder on the surface of the pull-out plate 3, thereby intercepting the dry powder, and the dry powder can directly fall onto the conductive copper sheet 4, thereby extinguishing the open flame.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
