Problems solved by technology

[0003] 1. The cost is too expensive; taking the deep-water cable sealing member that can be used in 5000m water depth as an example, the current supplier mainly provides two sets of cable plug sockets, and the price of each set is generally between RMB 600-1000. In this way, making a The cable needs 1200-2000 yuan, and the cable needs to be vulcanized by a special process before it can be used
If multiple cables are required on one set of equipment, the cost is a heavy burden for the average user
[0004] 2. Poor maintainability; since the vulcanization process is commo...

Embodiment Construction

[0017] The present invention includes two quick joints 1, 7 with thin hoses 2, 6, which are characterized in that they are also connected with a pair of variable diameter quick joints 3, 5 which are sealed and socketed by thick hoses 4, and are connected by The matching large sealing nut 11 is tightly connected.

[0018] The structure of the above-mentioned variable-diameter quick joint 3 and the variable-diameter quick joint 5 is the same. The structure of the above-mentioned variable-diameter quick connectors 3 and 5 is similar to that of the quick connectors 1 and 7 .

[0019] The essence of the above-mentioned variable-diameter quick connectors 3 and 5 is a quick connector with a small sealing nozzle 9 and a large sealing nozzle 10 screwed with a small nut 8 and a large nut 11 at both ends respectively.

[0020] The two quick connectors 1 and 7 are respectively connected to the sealed chamber body of the existing equipment, usually connected with a thread and a sealing ri...

Abstract

This invention relates to one underwater cable sealing structure, which Comprises soft tube rapid terminals and is characterized by the following: the one pair of varies radium joints between soft tubes are connected to be matched by sealed screw; Realizing thin and thick tubes two end sealing through inside tamper sealed mouth and screw. This invention realizes the sealing tube and its cable plug and socket; the above radium rapid plug is formed by small and large screw caps with small sealed mouth and large joint.

Description

technical field [0001] The invention relates to a sealing member for underwater cables. Background technique [0002] The cable sealing problem of underwater operation equipment has always been an important and difficult point in the related technical fields at home and abroad, because the sealing effect of the cable directly determines the working performance, service life and practicability of the underwater equipment. Therefore, the sealing member of the cable is The key components of underwater cables, relevant departments at home and abroad have developed a variety of underwater cable sealing components, mainly designed various underwater sealing connectors with rubber vulcanization, which can be used in water depths below 5000m. However, for small equipment operating in shallow water, the use of this type of sealing member has the following three disadvantages: [0003] 1. The cost is too expensive; taking the deep-water cable sealing member that can be used in 5000m ...
