Background
With the rapid development of the offshore wind power industry, offshore wind resources are developed continuously, and at present, the offshore wind power industry gradually develops towards deep sea. Compared with the traditional pile type foundation and jacket foundation and the floating type foundation, the floating type foundation has the advantages of being strong in adaptation to deep water conditions, capable of better utilizing wind energy resources and the like, and the advantages of the floating type foundation are more obvious along with the increase of water depth. At present, the installation and arrangement mode of a submarine cable between floating offshore wind power foundations is similar to that of a traditional pile foundation, the submarine cable on the foundation is buried under a seabed after being introduced into water, and due to the fact that the floating foundation is different from the traditional pile foundation, the floating foundation can move relatively greatly under environmental load, and the submarine cable is frequently abraded with the seabed. Meanwhile, the length of the sea cable needs to be long enough to prevent the sea cable buried under the seabed from being pulled out, so that the cost of the sea cable is increased.

The utility model will be further explained with reference to the drawings.
As shown in the figure, the installation structure of the submarine cable in the floating wind farm comprises at least two floating wind turbine bases 1, a submarine cable 2 connected between the floating wind turbine bases 1 in a matched mode and a mooring mechanism, wherein the mooring mechanism comprises a floating body 3 and mooring ropes 4, the floating body 3 is connected with the submarine cable 2 in a matched mode and used for providing buoyancy for the submarine cable 2, the upper end of each mooring rope 4 is connected with the floating body 3 in a matched mode, the lower end of each mooring rope is used for being tied and anchored on a seabed, and in addition, the upper end of each mooring rope 4 can be connected with the submarine cable 2 instead of the floating body 3 or connected with the floating body 3 and the submarine cable 2 simultaneously.
In some embodiments, there are multiple mooring lines 4 in the mooring mechanism.
In some embodiments, there is only one mooring mechanism, and the floating body 3 of the mooring mechanism is in fit connection with the middle of the sea line 2.
In other embodiments, when the distance between the floating wind turbine foundations 1 is too large, the mooring mechanism may be provided in plurality and spaced along the length of the sea cable 2.
In some embodiments, the floating wind turbine foundation 1 may be a Spar single-cylinder column wind turbine foundation, Semi-submersible wind turbine foundation, TLP tension leg wind turbine foundation or any other floating foundation form in which the main foundation structure is in direct contact with the seabed.
The utility model is mainly used for connecting the submarine cable in the field.
The floating body 3 in the present invention has sufficient buoyancy to counteract the dead weight of the sea cable 2.
The utility model has the following two implementation methods:
the method comprises the following steps: after the floating type fan foundation 1 is installed and positioned, the floating body 3 connected with the submarine cable 2 is transported to the measured erection position, the floating body 3 on the submarine cable 2 is positioned and fixed, and after mooring is completed, the submarine cable 2 is connected and guided to the floating type fan foundation 1 and connected to a fan.
The method 2 comprises the following steps: after the floating type fan foundation 1 and the floating body 3 are installed and positioned, the submarine cable 2 is installed, the submarine cable 2 is led out from one fan, passes through and is fixed on the floating body 3, and finally is connected to the next fan.
The utility model has the following advantages:
1) the direct contact between the submarine cable and the seabed can be avoided, the abrasion of the submarine cable is reduced, and the risk that the submarine cable is pulled out from the lower part of the seabed due to the movement of the floating type fan is avoided;
2) compared with an installation structure for burying the submarine cable underground on the seabed, the submarine cable is shorter in length, has no requirement on the seabed, and avoids the cost of sweeping the sea;
3) the utility model has wider applicability and is suitable for all floating foundations.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
