Construction method of seabed observation network system connection box integrated offshore deployment

Abstract

The invention relates to an integrated marine laying construction method for a submarine observation network system junction box. The integrated marine laying construction method is characterized by comprising the following steps: utilizing a water depth finder to measure the water depth of the preselected position of a seabed for laying the junction box, and using an underwater robot to determine the preselected condition of the seabed for laying the junction box; carrying out wiring at two ends of the junction box; connecting the junction box with a wire rope inside a deflecting pulley through a portal frame; lifting the junction box, laying the junction box towards the stem by the portal frame, the ship moving along a preset path direction at a certain speed, and stopping after the diving of the junction box; officially starting to lay the junction box to the seabed, moving the ship forwards at a certain speed along the path under the control of power positioning, and laying a submarine cable synchronously by a laying machine; once the monitored tension in the continuous laying process becomes smaller suddenly, stabilizing the tension to be the maximum value and then stopping the wire cable, and simultaneously stopping; stimulating a releaser underwater. All laying operations during laying of the junction box can be met by only one submarine cable construction ship.

Description

technical field [0001] The invention relates to a method for integrally deploying a junction box, an important device in a submarine observation network system, at sea, and belongs to the technical field of construction methods in the construction of a submarine observation network. Background technique [0002] In China, the submarine observation network system is a relatively new thing in the development of marine science, and it belongs to the initial stage of development. However, as the country attaches great importance to the development of the ocean industry in recent years, as an important part of the ocean industry, the construction of the submarine observation network project will increasingly highlight its importance in the future. On the one hand, it is beneficial to the scientific research of the underwater world; on the other hand, it will Play its important role in protecting national maritime security and homeland security. As the installation and deployment...

Problems solved by technology

[0004] At present, the domestic technology in the development and production of connection boxes is still in its infancy, and it is impossible to develop a connection box with wet plug-in function. However, in order to speed up the construction of the national observation network, it is still necessary to target the existing Offshore installation of junction boxes based on equipment and capabilities
