[0002] Cable bridging devices in nuclear power plants require sealed protection for cables due to the special nature of their operating environment. Existing nuclear power cable bridging devices, such as the "Adjustable Direction Nuclear Power Cable Tray" disclosed in application publication number CN102635733A, include at least two cable tray bodies, with a turning device between adjacent cable tray bodies.

[0028] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0029] Please see Figures 1-5 As shown, this invention proposes a nuclear power bridging device with adjustable routing function, including a mounting frame 1, a bridging frame 2 on the mounting frame 1, and multiple first cable troughs 3 on the bridging frame 2. Two first cable troughs 3 are respectively arranged on both sides of the bridging frame 2. One end of the bridging frame 2 is horizontally rotatably connected to two separation frames 4. Each of the two separation frames 4 is provided with a second cable trough 5, and the two second cable troughs 5 are respectively connected to the two first cable troughs 3. The two separation frames 4 are arranged opposite to each other. The bridging frame 2 is provided with two adjusting components to drive the two separation frames 4 to rotate. Nuclear power cables are placed in the two first cable troughs 3 respectively. The cables in the two first cable troughs 3 can be connected to different positions through the two second cable troughs 5 respectively. The two adjusting components drive the two separation frames 4 to rotate horizontally, thereby adjusting the horizontal angle of the two separation frames 4 and the second cable troughs 5 on them, thereby adjusting the horizontal transmission angle of the cables in the second cable troughs 5, and adjusting the transmission position of the cables to facilitate the bridging installation of the cables.

[0030] Each adjusting component includes a rotating rod 6 and a first adjusting gear 7. The separating frame 4 is rotatably connected to the bridging frame 2 via the rotating rod 6. The first adjusting gear 7 is installed at one end of the rotating rod 6. The bridging frame 2 is provided with a first transmission gear 8 that meshes with the first adjusting gear 7. The first transmission gear 8 is provided with a handle 9. The cable passes through the first cable trough 3 to the second cable trough 5. The handle 9 drives the first transmission gear 8 and the first adjusting gear 7 to rotate, thereby driving the separating frame 4 to rotate horizontally. This adjusts the horizontal angle of the separating frame 4 and the cable in the second cable trough 5, facilitating cable installation and wiring.

[0031] The first transmission gear 8 has multiple first fixing holes 17, which are arranged along the axis of the first transmission gear 8. The bridge frame 2 has a second fixing hole communicating with the first fixing holes 17. The throttle 9 is vertically slidably installed in the first fixing hole 17 and the second fixing hole. After the horizontal angle of the cable in the separation frame 4 and the second cable trough 5 is adjusted, the throttle 9 is vertically slidably installed in the second fixing hole and the corresponding first fixing hole 17, thereby fixing the horizontal angle of the cable in the separation frame 4 and the second cable trough 5.

[0032] Each separator 4 has a vertically rotatable connector 10 at the end furthest from the bridging frame 2. Each connector 10 has a third cable trough 11 that communicates with the second cable trough 5. The separator 4 has a drive mechanism for vertically rotating the connector 10. Cables pass through the first cable trough 3 and the second cable trough 5 to the third cable trough 11. The drive mechanism rotates the connector 10 vertically, adjusting the vertical alignment angle of the connector 10 and the cables within the third cable trough 11, thus facilitating cable connection.

[0033] The driving component includes a drive shaft 12 and a drive gear 13. The connector frame 10 is vertically rotatably connected to the separator frame 4 via the drive shaft 12. The drive gear 13 is located at one end of the drive shaft 12. A second adjusting gear 14, which meshes with the drive gear 13, is rotatably connected to the separator frame 4. The second adjusting gear 14 is equipped with a handle 15. The connector frame 10 is equipped with a fixing component for securing the drive gear 13 and the separator frame 4. By rotating the handle 15, the second adjusting gear 14 and the drive gear 13 are driven to rotate, thereby driving the drive shaft 12 and the connector frame 10 to rotate vertically, thus adjusting the vertical alignment angle of the connector frame 10 and the cables in its third cable tray 11.

[0034] Specifically, the fixing component includes a threaded bolt 18, a drive gear 13 with multiple first threaded holes 19 arranged along the rotation axis of the drive gear 13, and a separator 4 with a second threaded hole communicating with the first threaded holes 19. The threaded bolt 18 is threaded into the second threaded hole and the first threaded hole 19. After the vertical alignment angle of the cables in the connector 10 and its third cable trough 11 is adjusted, the threaded bolt 18 is threaded into the second threaded hole and the corresponding first threaded hole 19 to fix the vertical angle of the connector 10.

[0035] The first cable trough 3, the second cable trough 5, and the third cable trough 11 are equipped with multiple interconnected cable clamp slots 20. The bridge frame 2 is equipped with multiple cable stabilizers, which are located above the first cable trough 3. Multiple cables are installed and fixed by the multiple cable clamp slots 20, and the cables within the cable clamp slots 20 are fixed by the multiple cable stabilizers, thereby preventing cable movement.

[0036] The cable stabilizing component includes a rotating pressure plate 21, which is vertically rotatably connected to the bridge frame 2 and positioned above the cable clamping groove 20. A fixing pad 22 is provided on the side of the rotating pressure plate 21 closest to the cable clamping groove 20. The bridge frame 2 has a clamping groove for engaging the rotating pressure plate 21. When the cable is installed into the cable clamping groove 20, the rotating pressure plate 21 is engaged into the groove, thereby securing the cable within the clamping groove 20 with the fixing pad 22 on the rotating pressure plate 21, preventing cable movement.

[0037] The bridging frame 2, the separating frame 4, and the terminal frame 10 are all equipped with multiple snap-fit ​​holes 23. Each snap-fit ​​hole 23 contains a sealing plate 24, which sequentially seals the first cable trough 3, the second cable trough 5, and the third cable trough 11. After the cables are installed, the sealing plates 24 are sequentially snapped into the snap-fit ​​holes 23, thus sealing the first cable trough 3, the second cable trough 5, and the third cable trough 11 and protecting the cables.

[0038] The bridging frame 2 is located above the mounting frame 1. A threaded lifting rod 25 is vertically rotatably connected to the mounting frame 1. The bridging frame 2 is threadedly connected to the threaded lifting rod 25. Multiple telescopic guide cylinders 26 are vertically arranged between the mounting frame 1 and the bridging frame 2. By rotating the threaded lifting rod 25, the bridging frame 2 and its components are moved vertically, thereby moving the cable to the corresponding height position, facilitating the installation and fixing of the cable.

[0039] In use, the present invention uses a throttle 9 to drive the first transmission gear 8 and the first adjusting gear 7 to rotate, thereby driving the separator 4 to rotate horizontally and adjusting the horizontal angle of the cables in the separator 4 and the second cable trough 5. After the horizontal angle of the cables in the separator 4 and the second cable trough 5 is adjusted, the throttle 9 is vertically slidably installed in the second fixing hole and the corresponding first fixing hole 17 to fix the horizontal angle of the cables in the separator 4 and the second cable trough 5. By rotating the handle 15, the second adjusting gear 14 and the drive gear 13 are driven to rotate, thereby driving the drive shaft 12 and the connector 10 to rotate vertically, thereby adjusting the vertical alignment angle of the cables in the connector 10 and the third cable trough 11. After the vertical alignment angle of the cables in the connector 10 and the third cable trough 11 is adjusted, the threaded bolt 18 is threaded into the second threaded hole and the corresponding first threaded hole 19 to fix the vertical angle of the connector 10. By rotating the threaded lifting rod 25, the bridge frame 2 and its components are vertically moved, thereby moving the cables to the corresponding height position for easy installation and fixing of the cables.

[0040] Multiple cables are installed and fixed by multiple cable clamping slots 20. The rotating pressure plate 21 is clamped into the clamping slot, so that the fixing pad 22 on the rotating pressure plate 21 fixes the cable in the cable clamping slot 20 to prevent the cable from moving. Then, multiple sealing plates 24 are clamped into multiple clamping holes 23 in sequence, thereby completing the sealing of the first cable groove 3, the second cable groove 5 and the third cable groove 11, thus sealing and protecting the cable.
