[0001] The utility model relates to a 500kv high-voltage cable through-wall sealing structure, specifically a 500kv high-voltage cable through-wall sealing structure, belonging to the technical field of high-voltage cable through-wall. Background Technique

[0002] In the layout of high-voltage cable lines, especially when the cable needs to pass from one environment to another, such as from land to underwater or into different safety zones, in order to prevent flames, smoke, gases, and water from passing through the cable and pipe penetrations to adjacent structural parts, strict sealing measures must be adopted. This sealing structure not only protects the cable but also ensures the safety of personnel and property while maintaining the continuous operation ability of the equipment.

[0003] The existing high-voltage cable through-wall sealing structure is that the flange sleeve B on the cable is sealed and installed on the flange sleeve A. The sealing effect between the flange sleeve B and the flange sleeve A is ensured by the flange plate and the sealing gasket. The fixation between the two flange plates is carried out by multiple bolts. To ensure the sealing effect between the two flange plates, the bolts need to be tightened in a cross-sectional and segmented manner, so it is necessary to slowly and repeatedly tighten multiple bolts. This bolt fixation method requires multiple turns of the bolts and is rather cumbersome. Content of the Utility Model

The inner wall of the fixed seat is rotatably connected to a rotating shaft, and the fixed seat serves as a guide for the rotation of the rotating shaft.

[0010] One end of the rotating shaft close to the arc-shaped rack is fixedly connected with a gear, and the gear is meshed with the arc-shaped rack. When the rotating shaft is rotated, the rotating tube can be driven to rotate through the gear and the arc-shaped rack.

[0011] Furthermore, the driving mechanism also includes a supporting slide fixedly connected to the outer surface of the flange sleeve A, and a rotating disk is fixedly connected to one end of the rotating shaft close to the supporting slide.
