Description

Technical Field

[0001] The utility model relates to an offshore soft joint purification room device, belonging to the technical field of cables. Background Art

[0002] During the cable laying process, when the cable length is less than the laying length, two or more cable segments need to be connected so that the conductor cores of the cable are connected to form a continuous cable structure. During the connection operation, the cable joint must have good insulation and sealing performance and comply with electrical insulation regulations. The cleanliness and stability of the construction process directly affect the reliability of the cable line operation. During the cable joint preparation process, it is generally necessary to position the submarine cable maintenance ship to a fixed area and then carry out construction on the submarine cable maintenance ship. Due to the harsh marine environment, it is generally in a high temperature, high humidity, and high salt fog state, which seriously affects the electrical performance of the cable joint. During the cable joint preparation process, a special clean room is often required, and the temperature, humidity and particle size of the clean room are strictly controlled. During the preparation process, a series of treatments such as timely removal of harmful dust are carried out. The specific operation process is generally carried out on the operating table. Due to the strong wind and waves on the sea surface, the thickness of the various layers of the cable structure is often uneven during the joint processing process. Therefore, it is necessary to develop a soft joint clean room with better balance and cleanliness to improve the cleanliness and stability of the cable joint preparation process.
