However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] See Figure 1-3 In this embodiment of the utility model, the multi-terminal DC distribution network frame includes an installation frame 1, and further includes: a symmetrically arranged fixed frame 3, with a fixed base plate 4 at the bottom of the fixed frame 3; a first screw 6, the bottom of the first screw 6 being rotatably connected to the fixed base plate 4, and a rotation drive assembly for driving the first screw 6 to rotate is installed on the fixed base plate 4; a movable plate 11 is threadedly connected to the first screw 6, the movable plate 11 being fixedly connected to an L-shaped support frame 2, the L-shaped support frame 2 being symmetrically installed at both ends of the bottom of the installation frame 1; a bearing frame 15, the bearing frame 15 being fixedly connected to the center of the installation frame 1; an elastic clamping plate 19, the inner end of the elastic clamping plate 19 having a plurality of first cable routing holes 20 at equal intervals, the elastic clamping plate 19 being elastically connected to the bearing frame 15 through an elastic connection assembly; and a movable clamping plate 21, the inner end of the movable clamping plate 21 having a plurality of second cable routing holes 22 at equal intervals, and a movable drive assembly for driving the movable clamping plate 21 to clamp is provided at the center of the installation frame 1.

[0024] This invention uses a rotation drive assembly to drive the first screw 6 to rotate. The first screw 6 drives the threaded movable plate 11 to move up and down. The movable plate 11 simultaneously drives the L-shaped support frame 2 to move. The L-shaped support frame 2 simultaneously drives the mounting frame 1 to adjust its height. After the mounting frame 1 is adjusted in height, the elastic clamping plate 19 is driven to move through the elastic connection assembly. In conjunction with the movement drive assembly, the movable clamping plate 21 is driven to achieve stable clamping of multi-terminal DC power distribution cables, thereby facilitating the load-bearing processing of multi-terminal DC power distribution networks.

[0025] See Figure 1 In one embodiment of this utility model, the four corners of the fixed base plate 4 are threaded with mounting bolts 5. The mounting bolts 5 facilitate the fixed installation of the multi-terminal DC distribution network frame.

[0026] See Figure 1 In one embodiment of this utility model, the rotation drive assembly includes a drive motor 7 connected to a fixed base plate 4. A drive gear 8 is mounted on the motor shaft of the drive motor 7. A driven gear 9 is meshed on the drive gear 8. The driven gear 9 is fixedly connected to a first screw 6. When the drive motor 7 works, the drive motor 7 drives the drive gear 8 to rotate, and the drive gear 8 drives the meshed first screw 6 to rotate.

[0027] See Figure 1 In one embodiment of this utility model, a limiting block 10 is provided at the top of the first screw 6. The limiting block 10 can limit the movement plate 11 threadedly connected to the first screw 6, thereby ensuring the safe operation of the frame.

[0028] See Figure 1 In one embodiment of this utility model, guide screws 12 are fixedly provided at the four corners of the fixed frame 3. The guide screws 12 are slidably connected to the L-shaped support frame 2. Brake nuts 13 are threadedly connected to the guide screws 12 on both sides of the guide screws 12. After the height of the L-shaped support frame 2 is adjusted, the brake nuts 13 at both ends are driven to achieve stable installation of the L-shaped support frame 2, thereby facilitating stable load-bearing treatment of the frame after the position is adjusted.

[0029] See Figure 2 In one embodiment of this utility model, a plurality of cable fixing mounting brackets 14 are provided at equal intervals on the outer walls of the left and right ends of the mounting frame 1. The cable fixing mounting brackets 14 facilitate the installation and clamping of cables.

[0030] See Figure 2 In one embodiment of this utility model, the elastic connection assembly includes a plurality of connecting tubes 16 fixedly connected to the support frame 15. Each connecting tube 16 has a sliding member 18 at both ends. The sliding members 18 are interconnected by clamping springs 17. The outer end of the sliding member 18 is connected to an elastic clamping plate 19. When a cable is placed between the first cable hole 20 and the second cable hole 22, the elastic clamping plate 19 pushes the sliding member 18 to move inward. The clamping spring 17 is compressed to generate elastic force, thereby enabling the cable to be elastically clamped.

[0031] See Figure 2 In one embodiment of this utility model, guide rods 23 are provided at the four corners of the outer end of the movable clamping plate 21. The guide rods 23 are slidably connected to the mounting frame 1. The guide rods 23 can guide the movable clamping plate 21.

[0032] See Figure 2In one embodiment of this utility model, the moving drive assembly includes a second screw 24 threadedly connected to the center of the mounting frame 1. A knob 25 is provided at the outer end of the second screw 24, and the inner end of the second screw 24 is rotatably connected to the moving clamping plate 21. By driving the second screw 24 to rotate and move inward by driving the knob 25, the moving clamping plate 21 can be adjusted to move inward to clamp the cable.

[0033] Working principle: This utility model operates through a drive motor 7, which drives the active gear 8 to rotate. The active gear 8 drives the meshing driven gear 9 to rotate, and the driven gear 9 drives the first screw 6 to rotate. The first screw 6 drives the threaded movable plate 11 to move up and down adaptively. The movable plate 11, through the L-shaped support frame 2, enables the mounting frame 1 to be adjusted in height. The DC distribution network cables are sequentially embedded in the cable fixing mounting frame 14 for external cable storage. Each cable is then placed into the first cable hole 20 and the second cable hole 22. The drive knob 25 drives the second screw 24 to rotate and move inward. The second screw 24 drives the movable clamping plate 21 to move inward. With the help of the elastic clamping plate 19 set at the outer end of the elastic connection component, each cable is clamped, thus facilitating the installation of cables in multi-terminal DC distribution networks.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
