AI Technical Summary

Technical Problem

Existing cable clamping and sealing devices have difficulty in accurately controlling the tightening torque, which makes the cable prone to axial movement or shielding layer breakage, resulting in poor assembly quality consistency.

Method used

The clamping device includes a platform, a fixing plate, T-bolts, and an adapter sleeve. Combined with a torque wrench, the precise control of the clamping plug can be achieved by setting the torque value and the number of tightening turns.

Benefits of technology

This ensures the cable remains stable under high voltage, protects the shielding layer from damage, and improves the assembly quality and production efficiency of the sealing device.

Abstract

The application discloses a clamping device and a sealing method for a cable pressing sealing device, and belongs to the technical field of underwater sealing. In order to solve the technical problem that the cable is prone to axial movement or the shielding layer is broken due to the difficulty in controlling the tightening torque when the existing cable pressing sealing device is assembled, the application first provides a special clamping device, which comprises a platform, a fixed plate, a T-shaped bolt, an adapter sleeve with an open slot and a torque wrench. Based on the clamping device, the application further provides a sealing method, wherein the sealing hole cover is fixed to the clamping device, the torque wrench is connected with the pressing screw plug through the adapter sleeve, and the pressing screw plug is tightened step by step with an accurate torque value and the number of tightening turns. The torque value is 15 N.m, and the number of tightening turns is 2 turns. The application accurately controls the compression amount of the rubber pad by combining the tightening torque and the number of tightening turns, ensures the position stability of the cable and prevents the damage of the shielding layer, and significantly improves the assembly quality and the qualification rate of the product.
