The mooring reinforcing device for the offshore wind power single pile foundation 200 of the embodiment comprises a collar 100, a mooring rope 101, a tensioning power part 102, an anchoring foundation 110 and other structures. The offshore wind power single pile foundation 200 is a circular pipe pile, the collar 100 is welded on the mud upper part of the single pile foundation 200 in a circumferential direction, the collar 100 is generally positioned on the water surface, and the corrosion of seawater to the collar 100 and the tensioning power part 102 can be reduced. The collar 100 is connected with the single pile foundation 200 through the mooring cable 101, and the mooring cable 101 is used for transmitting the traction force of the anchoring foundation 110 to the single pile foundation 200, namely providing a horizontal resistance force for the single pile foundation 200, enhancing the stability of the single pile foundation 200 in the horizontal direction, and enabling the single pile foundation 200 to be suitable for larger water depths.
In this embodiment, the anchoring foundation 110 may be selected from the group consisting of a gravity anchor, a pile anchor, a suction anchor, a dynamic penetration anchor, and a vertical plate anchor, but as the water depth increases, the advantages of the suction anchor, the dynamic penetration anchor, and the vertical plate anchor are more obvious, and the installation and recovery of the suction anchor are simpler, so in the preferred embodiment, the anchoring foundation 110 is selected from the group consisting of a suction anchor.
In this embodiment, the collar 100 is provided with a tensioning power part 102, and the tensioning power part 102 can adjust the tensioning degree of the mooring cable 101 through the operation of a mechanism of the tensioning power part, so as to adjust the tension applied to the single pile foundation 200. In a conceivable embodiment, the tensioning power part 102 is a device capable of pulling the mooring line 101, such as a hydraulic cylinder, a hydraulic motor, an electric motor, or a hoist.
In this embodiment, the tensioning power portion 102 and the tension sensor 103 are disposed in a matching manner, so that the mooring rope 101 can be passively tensioned and adjusted according to the tension of the perceived wind wave on the mooring rope. The working principle of the single pile foundation is that the single pile foundation 200 can be bent and deformed to a small extent under the action of wind and wave flow, so that the stress of the mooring rope 101 in all directions is changed, particularly the stress of the mooring rope 101 in a local direction is increased, when the tension sensor 103 in the part of the direction senses that the tension of the mooring rope 101 is increased, the tension power part 102 in the direction starts to work, and the pulling force is applied to the mooring rope 101 in the direction in the modes of pulling, winding and the like, so that the single pile foundation 200 can be kept in a normal and stable state.
In a conceivable embodiment, the collar 100 may be arranged in a plurality along the vertical direction of the monopile foundation 200, the tensioning power unit 102 may be arranged in a plurality along the circumference of the collar 100, and the corresponding anchoring foundation 110 should be arranged in a plurality, so as to increase the number of mooring lines 101, thereby achieving the purpose of increasing the stability of the monopile foundation 200.
It is conceivable that when a plurality of collars 100 are arranged in the vertical direction of the monopile foundation 200, tensioning power portions 102 facing in the same direction may exist on collars 100 of different heights, and mooring lines 101 are connected to the tensioning power portions 102, respectively, and the mooring lines 101 may be connected to the same anchor foundation 110 in the corresponding direction, or may be connected to different anchor foundations 110, respectively.
In a conceivable embodiment, the number of mooring lines 101 connected to one collar 100 is typically 3 to 6, and in general, 4 tensioning power units 102 and mooring lines 101 are arranged on a single collar 100.
Collar 100 is typically disposed on the mud top portion of single pile foundation 200, so collar 100 may be disposed below or above the water surface, and in a preferred manner collar 100, tensioning power portion 102, and related structures are disposed above the water surface. For a collar 100 below the water surface, the collar 100, tensioning power section 102 and related structures should be provided with certain corrosion protection measures.
With reference to the foregoing embodiments, according to the mooring reinforcing device for the offshore wind power single pile foundation 200 of the present embodiment, by using the tensioning power portion 102, the tension sensor 103 and other arrangements, the tension of the mooring cable 101 to the single pile foundation 200 can be adjusted according to the influence of the perceived wind wave on the single pile foundation 200, so as to improve the bearing capacity and stability of the offshore wind power single pile foundation 200, and in particular, the mooring reinforcing device can be applied to the offshore wind power large-diameter single pile foundation 200, so that the offshore wind power single pile foundation 200 can adapt to larger water depth and has better use effect.
Example 2
1-4, Compared with the technical scheme of the embodiment 1, the offshore wind power single pile foundation mooring reinforcing device can be improved as follows: the loop 100 is provided with a wire guide wheel 104, the wire guide wheel 104 is positioned at one side of the tensioning power part 102 facing the output end, and the mooring cable 101 is abutted with one side of the wire guide wheel 104, which is close to the loop 100.
In this embodiment, by providing the wire guide wheel 104 on the collar 100, the mooring line 101 can be guided to change its extension direction, thereby changing its pulling direction. The purpose of changing the tension direction of the mooring line 101 is that when the output end of the tensioning power part 102 adopts a mechanism of stretching motion along the vertical direction, the motion direction of the output end is kept consistent with the tension direction as much as possible, and the tensioning power part is an adaptive implementation mode, so that the transmission of force can be better realized.
Taking a hydraulic cylinder as an example, the output shaft of the hydraulic cylinder moves along the linear direction, and can provide good traction force in the direction of the movement axis, if the wire guide wheel 104 is arranged, the traction force direction of the mooring rope 101 is consistent with the movement direction of the output shaft, so that the traction force is better transferred. If the mooring line 101 forms an angle with the output shaft, on the one hand, the pulling force cannot be well transmitted, and on the other hand, the tensioning power part 102 such as a hydraulic cylinder and the like can be damaged.

The present embodiment is an arrangement of the suction anchor, in which the bottom of the suction anchor body 111 is provided with a blade angle 112, that is, by cutting the steel plate of the bottom into a blade shape, the resistance when penetrating the seabed can be reduced to a great extent.
And, in this embodiment, a pumping part 113 is further provided, where the pumping part 113 is a combination of a water outlet and a pump body, and is used for pumping out seawater in the anchor body after the suction anchor is immersed in the sea floor for a certain depth.

The triangular pull-out resistance wing plate 114 in the embodiment can increase the resistance of the suction anchor to upward movement after the suction anchor is submerged into the seabed, thereby enhancing the pull-out resistance of the suction anchor.
Example 6
Referring to fig. 1-4, compared with any one of the technical schemes in embodiments 1-5, the offshore wind power single pile foundation mooring reinforcing device of the embodiment can be improved as follows: wherein the top of the anchoring foundation 110 is provided with lifting lugs 115.
Example 7

In this embodiment, the mooring 117 may be a connection member such as a ring member for fixedly connecting with the mooring line 101.
Example 9
Referring to fig. 1-4, compared with any one of the technical schemes in embodiments 1-8, the offshore wind power single pile foundation mooring reinforcing device of the embodiment can be improved as follows: the tensioning power part 102 is a hydraulic cylinder, the output end of the hydraulic cylinder is a hydraulic rod, and the end part of the hydraulic rod is fixedly connected with the mooring cable 101. In the embodiment, the hydraulic cylinder converts the hydraulic pressure energy into the mechanical energy of the output shaft of the hydraulic cylinder, and the hydraulic cylinder is simple in structure, reliable in operation and capable of being well adapted to the working environment of offshore wind power.
Example 10
Referring to fig. 1-4, compared with any one of the technical schemes in embodiments 1-9, the offshore wind power single pile foundation mooring reinforcing device of the embodiment can be improved as follows: the mooring line 101 is at an angle of 30 to 60 degrees to the horizontal.
In this embodiment, the angle between the mooring line 101 and the horizontal plane is affected by the relative positional relationship between the anchoring foundation 110 and the single pile foundation 200, and it is conceivable that if the angle is too large, this means that the anchoring foundation 110 is further distributed relative to the single pile foundation 200, which reduces the convenience of construction to some extent for offshore construction; however, if the included angle is too small, the upward force component will be relatively large for the force applied to the anchoring base 110, which may affect the stability of the anchoring base 110. The mooring line 101 may thus be at an angle of 30 to 60 degrees to the horizontal, which in a preferred embodiment may be around 45 degrees.
The utility model and its embodiments have been described above schematically, without limitation, and the actual construction is not limited to this, as it is shown in the drawings, which are only one of the embodiments of the utility model.
