Problems solved by technology

[0006] At present, most highly integrated equipment such as underwater robots are used for the laying of multi-tube foundations. The construction and installation costs are high, which greatly increases the installation cost of multi-tube foundations, which is not conducive to the large-scale promotion and use of multi-tube foundations.
[0007] In addition, the use of multi-tube foundations in my country is in the exploratory stage, and the penetration control technology is still immature, which limits the further development of multi-tube foundations

Embodiment 1

[0109] For the present invention, the dry tank skid 2 may be provided on only one cylinder in the multi-cylinder foundation 1 . The specific structure is as follows:

[0110] A dry-type cabin skid 2 is arranged on the top of a cylinder in the multi-cylinder foundation 1;

[0111] The multi-cylinder foundation 1 and the dry tank skid 2 are connected through the upper blind flange 4 and the lower blind flange 5.

[0112] In terms of specific implementation, for the multi-cylinder foundation 1, a lower blind flange 5 is welded on the top of one of the cylinders;

[0113] The bottom of the dry cabin skid 2 is welded with an upper blind flange 4;

[0114] The upper blind flange 4 and the lower blind flange 5 are rigidly connected (for example, bolt connection can be used);

[0115] It should be noted that the upper blind flange 4 and the lower blind flange 5 are rigidly connected, and the connection and sealing process is performed.

[0116] In terms of specific implementation,...

Embodiment 2

[0170] Below the present invention, the dry tank skid 2 can be in various forms, such as Figure 8 As shown in the figure, the method of "one barrel and one skid" is adopted, and each dry tank skid 2 controls one barrel to avoid laying pipelines, and the structure is simple, which is also beneficial to the sinking installation of multi-cylinder foundations.

[0171] That is to say, for the present invention, one dry-type cabin skid block 2 can be respectively arranged on each cylinder in the multi-cylinder foundation 1 respectively. The specific structure is as follows:

[0172] The top of each cylinder in the multi-cylinder foundation 1 is respectively provided with a dry-type cabin skid 2;

[0173] Each dry tank skid 2 includes a hollow sealed dry tank shell 27;

[0174] It should be noted that the dry tank shell 27 is a sealed structure, and the rigidity is sufficient to resist the high pressure in deep water.

[0175] The bottom center position of the dry tank shell 27 ...

Abstract

The invention discloses a dry-type cabin skid block structure and a pipeline system suitable for laying down a multi-cylinder foundation, which comprises a multi-cylinder foundation and a dry-type cabin skid block; the multi-cylinder foundation comprises three hollow and bottom-opening Cylinder body; multi-tube foundation, which is used to carry out the mud feeding operation to the seabed under the action of its own weight when it is put into sea water; the top of the multi-tube foundation is provided with a dry tank skid; the dry tank skid, It is communicated with the inner space of each cylinder through a water pipeline, which is used to extract the water in each cylinder in the multi-cylinder foundation when the cylinder completes the mud feeding operation to the seabed under the action of its own weight, so that the multi-cylinder foundation can be Negative pressure is generated inside, so as to achieve gradual sinking, until each cylinder goes deep into the seabed to a preset depth. Aiming at safety, high efficiency and low cost, the invention adopts the dry-type cabin skid block structure to replace the expensive existing underwater robot structure, greatly reduces the cost of laying down the multi-tube foundation, and ensures the smooth installation of the multi-tube foundation in place.

Description

technical field [0001] The invention relates to the technical field of offshore wind power, in particular to a dry-type cabin skid block structure and a pipeline system suitable for laying down a multi-tube foundation. Background technique [0002] At present, with the adjustment of the global energy structure, all countries in the world are vigorously promoting the clean and low-carbon development of the energy system, promoting low-carbon energy to replace high-carbon energy, and renewable energy to replace fossil energy. Offshore wind power, as a clean energy source, is rich in resources, has huge development potential, and is close to the urban load center, so it is convenient for local consumption. Therefore, the development of offshore wind power will become an important strategic support for the transformation of the global energy structure. [0003] In recent years, my country's offshore wind power has developed rapidly. However, the development area is mostly concen...
