Watertight connecting device for underground cable connector

Abstract

The invention provides a watertight connecting device for an underground cable connector. The device comprises an inner sealing barrel and an outer sealing barrel; the outer sealing barrel is arranged at an outer layer of the whole device, and the inner sealing barrel is arranged in the outer sealing barrel, and the two ends of the inner sealing barrel are symmetric; a cable A and a cable B are respectively arranged in the middle parts of the outer sealing barrel and the inner sealing barrel; the inner sealing barrel comprises an inner barrel watertight locking structure, an extruding rubber ring and an inner barrel body; the outer sealing barrel comprises an outer barrel watertight locking structure, an outer barrel end cover seat A, an outer barrel body, a glue injection hole sealing cap, an outer barrel end cover seat B and an anchoring structure. The watertight connecting device adopting the structure above is easily assembled, low in operation requirement, and high in reliability; the tensile strength of the cables is remained, core wires of the cables are sealed in three layers and the cables are avoided any damage, so that the device is particularly suitable for underground cable repair and the condition that the underground cable is damaged and to be timely treated and re-connected; with the adoption of the device, the strain capacity of underground cable repair can be greatly improved.

Description

technical field [0001] The invention relates to a watertight connection device for an underwater cable joint, which is particularly suitable for a watertight connection device for an underwater cable joint that needs to be dealt with and reconnected in time for repair or damage of an underwater cable. Background technique [0002] Generally speaking, underwater construction involves many vessels and personnel, complex equipment and high cost. Because underwater cables are damaged from time to time or damaged after long-term use, sometimes there is an emergency to reconnect the cables. , Because the traditional cable joint watertight connection device needs to be prepared in advance before use, if there are no pre-measures and preparations, it is impossible to quickly connect and repair damaged or leaking cables, and it cannot solve the problems in underwater construction. , and may even stop work at sea or return to the voyage, which will cause greater waste of personnel and...
