Sealing device for submarine cable water resistance test

Abstract

The invention discloses a sealing device for a submarine cable water resistance test. The sealing device comprises a test tank, a temperature measuring port, a pressure gauge port, a water inlet, a flange gland, a movable pulley, and a water outlet; the temperature measuring port, the pressure gauge port and the water inlet are respectively arranged at the top of the test tank; the flange gland is respectively arranged on two ends of the test tank; the movable pulley and the water outlet are arranged at the bottom of the test tank; multiple cable core through holes are formed in the middle of the flange gland; multiple cable core fixing screw sockets arranged radially are arranged around the cable core through holes; multiple screw fixing holes are radially arranged on the side of the flange gland. In the sealing device, water temperature monitoring, water pressure monitoring and a movable structure are adopted; through online water temperature monitoring, test time nodes can be effectively controlled and test time is ensured; based on design of real-time water pressure monitoring, the tank pressure can be monitored so that the water pressure of the submarine cable is ensured in the design scope, effective test data are provided for research and development test and the watertight test capacity of the submarine cable is greatly increased.

Description

technical field [0001] The invention relates to a sealing device for a submarine cable water blocking test, in particular to a sealing tank for a longitudinal water blocking test of a submarine photoelectric composite cable core. The invention belongs to the technical field of electric wire and cable inspection. Background technique [0002] Submarine cables are laid in wading work such as oceans or lakes. In order to ensure the normal operation of the submarine cable, it is necessary to do a good job of waterproofing and sealing of the submarine cable. The water resistance of the submarine cable is an important indicator of the entire submarine cable. Corresponding Watertight test The test device also needs to simulate the seabed water pressure to verify the water resistance performance of the submarine cable. At present, ordinary watertight pressure tanks can no longer meet the water resistance test of large cross-section, high voltage and deep water submarine cables. Con...

[0002] Submarine cables are laid in wading work such as oceans or lakes. In order to ensure the normal operation of submarine cables, it is necessary to do a good job of waterproofing and sealing of submarine cables. The water resistance performance of submarine cables is an important indicator of the entire submarine cable. Corresponding Watertight test The test device also needs to simulate the seabed water pressure to verify the water resistance performance of the submarine cable. At present, ordinary watertight pressure tanks can no longer meet the water resistance test of large cross-section, high voltage and deep water submarine cables.
