[0014] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate the understanding of technicians.

[0015] like Figure 1-3 As shown, the utility model provides a power transmission and transformation engineering distribution box, including a box body 1, a box door 2, a movable mounting plate 3, and a driving mechanism 4; the box door 2 is installed on the box body 1, and the movable mounting plate 3 is installed in a slide groove 6 provided on the inner wall of the box body 1 by sliding blocks 5 arranged around it; the driving mechanism 4 is installed on the box body 1 and is drivingly connected to the movable mounting plate 3, and each component in the box body 1 is installed on the movable mounting plate 3. When the distribution box is inspected, the box door 2 is opened, and the driving mechanism 4 is started to drive the movable mounting plate 3 to slide forward along the slide groove 6 provided on the inner wall of the box body 1, so that the components on the movable mounting plate 3 move forward out of the box body 1, and then the components are inspected. After the inspection is completed, the movable mounting plate 3 drives the components to return to the box body 1 through the driving mechanism 4, and the box door 2 is closed, so as to facilitate the inspection of the components in the distribution box, improve the efficiency of the inspection of the distribution box, and avoid the narrow space in the distribution box and the inconvenience of operation.

[0016] The driving mechanism 4 includes a screw 7, a dual-axis motor 8, and a transmission rod 9. The screw 7 is installed in the slide grooves 6 set on both sides of the box body 1 and is threadedly connected to the slider 5; the dual-axis motor 8 is installed in the protective frame 10 set on the back of the box body 1, and the two output shafts are respectively connected to the transmission rods 9, and the ends of the two transmission rods 9 are respectively connected to the ends of the screw 7 on both sides through worm gear transmission. The dual-axis motor 8 drives the transmission rod 9 to rotate, and the transmission rod 9 drives the screw 7 to rotate through the worm gear. The screw 7 and the sliders 5 on both sides of the movable mounting plate 3 rotate relative to each other through the threads, thereby pushing the movable mounting plate 3 to move along the slide groove 6, pushing the components out of the box body 1, and facilitating maintenance. The driving mechanism 4 can conveniently and quickly move the components, thereby improving the maintenance efficiency of the distribution box.

[0017] The back of the box body 1 is provided with a fixing mechanism for facilitating the installation of the distribution box, and the fixing mechanism includes an adjusting screw 11, an arc-shaped fixing piece 12, and a locking bolt 13. The adjusting screw 11 is installed in a strip groove 14 provided on the protective frame 10 through a bearing, and two arc-shaped fixing pieces 12 are provided, one end of which is threadedly connected to the adjusting screw 11, and the other end is connected through the locking bolt 13. When installing the distribution box, the two arc-shaped fixing pieces 12 are clamped on both sides of the electric pole, and then the adjusting screw 11 is rotated, and the adjusting screw 11 and the arc-shaped fixing piece 12 are threadedly rotated, so that the arc-shaped fixing piece 12 moves on the adjusting screw 11 and is clamped on the electric pole, and then the end of the arc-shaped fixing piece 12 is locked by the locking bolt 13, so that the distribution box is installed on the electric pole. The distribution box is installed on the electric pole through the fixing mechanism, which is stable and easy to install, thereby improving the efficiency of the distribution box installation.

[0018] The two arc-shaped fixing pieces 12 are connected to the adjusting screw rod 11 in opposite directions of the screw thread. When the adjusting screw rod 11 is rotated, the two arc-shaped fixing pieces 12 can be moved in opposite directions, so that the arc-shaped fixing pieces 12 can be clamped and fixed on the electric pole.

[0019] The upper and lower parts of the back of the box body 1 are equipped with support blocks 15 with arc grooves at the ends. When the distribution box is installed on the electric pole, the arc groove of the support block 15 is stuck on the electric pole, which can support and fix the distribution box, thereby increasing the stability of the distribution box installation.

[0020] Working process:

[0021] When inspecting the distribution box, open the box door 2, start the driving mechanism 4 to drive the mobile mounting plate 3 to slide toward the slide groove 6 set on the inner wall of the front box body 1, and drive the transmission rod 9 to rotate through the dual-axis motor 8. The transmission rod 9 drives the screw rod 7 to rotate through the worm gear. The screw rod 7 and the sliders 5 on both sides of the mobile mounting plate 3 rotate relative to each other through the thread, thereby pushing the mobile mounting plate 3 to move along the slide groove 6, so that the components on the mobile mounting plate 3 move forward out of the box body 1, and then the components are inspected. After the inspection, the mobile mounting plate 3 is driven by the driving mechanism 4 to move the components back into the box body 1, and the box door 2 is closed, so as to facilitate the inspection of the components in the distribution box, improve the efficiency of the distribution box inspection, and avoid the narrow space in the distribution box and the inconvenient operation.

[0022] When installing the distribution box, two arc-shaped fixing pieces 12 are clamped on both sides of the electric pole, and then the adjusting screw 11 is rotated to make the arc-shaped fixing piece 12 move on the adjusting screw 11 and clamped on the electric pole, and then the end of the arc-shaped fixing piece 12 is locked by the locking bolt 13, so that the distribution box is installed on the electric pole. At the same time, the arc-shaped groove of the support block 15 is stuck on the electric pole, which can support and fix the distribution box. The distribution box is installed on the electric pole through the fixing mechanism, which is stable and easy to install, thereby improving the efficiency of the distribution box installation.
