Problems solved by technology

Therefore, the installation method of the above-mentioned protective tube has low installation efficiency and accuracy; and has many disadvantages such as high cost, divers need to wait for the flat tide time of the working water area, etc., so in the installation method after the cable protective tube, a cable protective tube is created. Handy tool for post-installation becomes imperative

Embodiment Construction

[0024] like figure 1 — image 3 As shown, the present invention includes: a sleeve connected to one or more cable protection tubes 3, and a riser connected to the sleeve by welding; wherein, the connection between the sleeve and multiple cable protection tubes 3 is on land The overall preset is completed; the sleeve ring 1 is arranged at a certain distance on the sleeve, and the support structure 2 is arranged on the side opposite to the standpipe by welding. The function of the support structure 2 is to make the whole structure form a complete closed loop.

[0025] The distance between the above-mentioned sleeve rings 1 on the sleeve is 3 to 5 meters. If the water depth is relatively shallow, the distance between the sleeve rings 1 can be adjusted flexibly. The diameter of the sleeve rings 1 is from bottom to bottom (after installation The direction close to the seabed is the downward direction) and the upward direction (the direction of the sea surface is the upward direct...

Abstract

A single-pile multi-cable protective tube installation sleeve device includes: sleeves respectively connected to several cable protective tubes, and a riser connected to the sleeves; wherein, the connection between the sleeve and the several cable protective tubes is It is preset as a whole on land; sleeve rings are arranged at a certain distance on the sleeve, and a support structure is provided on the side opposite to the riser to make the entire structure form a complete closed loop. The invention not only can quickly install one or more cable protective pipes at one time, greatly reduces the offshore construction cost of a single cable protective pipe, and improves the construction efficiency and installation accuracy; moreover, it saves the offshore construction period and oil field development costs. At the same time, it also reduces the construction fee of more than 2 million yuan for the construction party to install cable protection pipes offshore.

Description

technical field [0001] The invention relates to cable protection pipes, in particular to a single-pile multi-cable protection pipe installation sleeve device used in ocean engineering. It belongs to the field of offshore oil engineering. Background technique [0002] There are many occasions in marine engineering where it is necessary to lay submarine cables, which can be hundreds of kilometers long, and the shortest cables may only be tens of meters. Submarine cables are mostly used for power and signal transmission on offshore oil platforms or offshore wind power generation. The cables in the ship generally need to be protected by the cable protection tube to climb from the seabed to the offshore structure. Taking offshore wind power generation as an example, at present, in domestic and foreign wind power development projects, single pile structures are mostly used as the foundation of offshore wind turbines and single pile foundations of offshore power generation booster...
