The protective member includes a connecting plate 3, a connecting rod 31 is fixedly connected to the surface of the connecting plate 3, and a protective plate 32 is rotatably connected to the surface of the connecting rod 31. Three horizontal mounting plates 21 are screwed to the upper surfaces of the two vertical mounting plates 2 on the same side, and a vertical mounting plate 22 is screwed to the center of the surface of the horizontal mounting plate 21, and five horizontal mounting plates 23 are screwed to the surface of the vertical mounting plate 22.

[0044] Implementation process: Rotate and open the cabinet door 11, select protective plates 32 of different specifications according to different sizes of GGD electric control cabinets, align the protective plates 32 with the live copper bus and wires installed on the surface of the horizontal mounting plate 23 to isolate them, and insert the fixing parts connected to the inner surface of the connecting plate 3 into the position of the fixed protective plate 32 in the vertical mounting plate 2. The protective plate 32 is made of insulating acrylic plate.

[0045] Implementation benefits: It realizes the protection of live copper busbars, allowing electrical maintenance personnel to conduct daily inspections of the electric control cabinet.

[0046] Example 2

[0047] The fixing part includes a latch 4, a rotating ring 41 is fixedly connected to the outer surface of the latch 4, and a sliding hole matching the rotating ring 41 is provided inside the connecting plate 3. A rotating block 42 is slidably connected to the upper side of the inner surface of the latch 4, a spring 1 43 is fixedly connected between the upper surface of the rotating block 42 and the top of the inner part of the latch 4, and a sliding rod 44 is rotatably connected to the lower surface of the rotating block 42. A fixed block 45 is fixedly connected to the outer surface of the rotating block 42, and a fixed slide 46 is provided on the surface of the latch 4 at the position of the fixed block 45. The fixed block 45 passes through the fixed slide 46 and is slidably connected to the fixed slide 46, and the fixed slide 46 is provided in a heptagonal shape. Two notches 47 are symmetrically provided on the surface of the lower side of the latch 4 and the sliding rod 44, a connecting rod 2 48 is fixedly connected to the inner wall of the lower side of the sliding rod 44, a fixed plate 49 is rotatably connected to the outer surface of the connecting rod 2 48, a spring 2 410 is fixedly connected between the fixed plate 49 and the sliding rod 44, and the notch 47 is provided in a rectangular shape.

[0048] Implementation process: When installation is required, push the latch 4 to insert into the through hole opened on the surface of the vertical mounting plate 2. The fixing plate 49 rotates close to both sides under the elastic force of the spring 2 410. When passing through the through hole on the vertical mounting plate 2, the spring 2 410 drives the fixing plate 49 to unfold, so that the fixing plate 49 is against the surface of the bottom side of the vertical mounting plate 2 for fixing. When maintenance and disassembly are required, push the fixing block 45 to slide to the inner surface close to the rotating ring 41 under the restriction of the fixed slide groove 46. The sliding of the fixing block 45 drives the sliding rod 44 inside the latch 4 to move to the side close to the connecting rod 2 48. Because the connecting rod 2 48 is rotatably connected to the fixing plate 49, the connecting rod 2 48 is fixedly connected to the inner wall of the sliding rod 44, and the notch 47 is opened. On the sliding rod 44 and the latch 4, moving the sliding rod 44 will drive the connecting rod 2 48 and the fixed plate 49 to move downward. Under the restriction of the bottom end of the latch 4, the fixed plate 49 rotates in the direction close to the sliding rod 44 to the inside of the groove 47, and the rotating block 42 is connected to the sliding rod 44 through the rotation of the sliding block 42. The fixing block 45 is rotated clockwise to drive the rotating block 42 to rotate. Under the elastic force of the spring 1 43, the fixing block 45 is stuck into one end of the fixed slide groove 46, thereby fixing the position of the fixing plate 49, and the latch 4 is pulled out. Under the action of the connecting rod 1 31, the connecting plate 3 is rotated to release the protective effect of the protective plate 32 at one end, and the protective plate 32 at the other end continues to be fixedly connected to the vertical mounting plate 1 2 through the latch 4, the connecting rod 1 31 and the connecting plate 3.

[0049] Implementation benefits: Easy to disassemble and repair internal electrical equipment.
