Example Embodiment

[0023] Such as Figure 1 to Figure 5 The shown dynamic cable seal limit anchoring structure includes a front anchor 1 and a rear anchor 2. The front anchor 1 and the rear anchor 2 are each provided with a cavity and one end is provided with a through hole. The through hole and the cavity penetrate each other, the front anchor 1 and the rear anchor 2 are connected to each other and the two cavities are butted to each other, and the joint of the front anchor 1 and the rear anchor 2 is provided with a sealing groove 8, so A first sealing ring 7 is provided in the sealing groove 8, and a cover plate 3 is provided at the ends of the front anchor 1 and the rear anchor 2 and between the front anchor 1, the rear anchor 2 and the cover 3 With a second sealing ring 6.

[0024] As a further optimization of the above technical solution:

[0025] Further, the first sealing ring 7 adopts an O-shaped sealing ring.

[0026] Further, the second sealing ring 6 adopts a fluorine rubber sealing ring....

Abstract

The invention discloses a dynamic cable seal position-limiting anchor structure, which includes a front anchor and a rear anchor. Both the front anchor and the rear anchor are provided with cavities and one end is provided with a through hole. The through hole is connected to the The cavities communicate with each other, the front anchor and the rear anchor are connected to each other and the two cavities are connected to each other, and the junction of the front anchor and the rear anchor is provided with a sealing groove, and the sealing groove is provided with a first A sealing ring, the ends of the front anchor and the rear anchor are provided with a cover plate, and a second sealing ring is provided between the front anchor, the rear anchor and the cover plate. The invention ensures the cohesive force of the submarine cable entering the anchoring device, and at the same time, the positioning function can facilitate and timely adjust the construction, and the overall water tightness is also well handled. The anchorage provided by the invention can be thrown into the sea along with the cable body, which improves the installation efficiency and reduces the installation cost.

Description

technical field [0001] The invention belongs to the field of electric power transmission, in particular to an anchoring structure for sealing the middle part of a multilayer armored dynamic cable. Background technique [0002] The dynamic submarine cable is a comprehensive cable that transmits power and communication control signals with dynamic changes in position and stress state. It has broad development and application space for marine industry power transmission and communication control signal transmission. Based on the specific needs of marine resources development, this project will form a dynamic submarine composite cable system design capability that meets engineering needs, develop armored cables and accessories with strong adaptability and high operational stability, and develop fatigue life test and dynamic sealing test technology. [0003] The end of the dynamic cable is generally fixed on the ship or platform deck and bears a relatively severe dynamic load. Th...
