Quick-insertion cable joint for underwater butt joint

Abstract

The invention, which relates to the technical field of electric power laying, provides a quick-insertion cable joint for underwater docking, comprising a main body, the front side of which is provided with a docking head through a bolt in a locking manner; conveying cylinders are slidably inserted into the left and right ends of the butt joint. A loading groove is formed in the circumferential outer wall of the conveying cylinder; conveying gears are fixedly installed on the middle sections of the conveying rods, and every two adjacent conveying gears in the front-back direction are connected in a meshed mode. According to the invention, the hydraulic pressure is used as a driving force to better ensure that the cables are fully butted, so that the situation that the cables are not thoroughly butted due to insufficient self-strength during manual cable butting is avoided, and the butting work does not have an operation for testing the technology; therefore, the cable butt joint work has a lower threshold for the strength demand of workers and the technical level, and the problems that the cable butt joint is not thorough and the cable butt joint cannot be ensured fully due to the insufficient strength of operators during the manual butt joint of the existing joint are solved.

Description

technical field [0001] The invention relates to the technical field of electric power layout, in particular to a quick-installed cable joint used for underwater docking. Background technique [0002] When the cable is laid, it will inevitably be laid underwater due to environmental reasons, and due to the limited length of the cable, the complete power layout may need to be composed of more cables, and cable joints need to be used when the cables are connected and combined. [0003] However, as far as the current traditional cable joints are concerned, most of them need to manually insert one end of the two cables into the joint in turn for butt joint, and there is a certain pressure underwater, and the operator may cause the cable joint to be incomplete due to the lack of their own strength during manual docking. , it is impossible to ensure that the cables are fully docked, so the docking work has a high threshold for the operator's physical fitness, qualifications, experi...

Problems solved by technology

[0003] However, as far as the current traditional cable joints are concerned, most of them need to manually insert one end of the two cables into the joints for docking, and the underwater has a certain pressure. When manually docking, the operator may not be able to complete the cable docking due to his own lack of strength. , it is impossible to ensure that the cables are fully docked, so the docking work has a high threshold for the operator's physical fitness, qualifications, experience, and technical level, and the two cables cannot be automatically fully docked by using the underwater pressure as the medium through structural improvement;

[0004] In addition, the existing joints cannot automatically discharge the accumulated water at the cable docking position when the cables are docked. Too much water is not conducive to putting the connected cables into use as soon as possible, and the existing connectors still need to be used manually after the cables are docked. The waterproof tape wraps and seals the cable connection part, which is inconvenient to operate
