[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0048] like Figures 2 to 6 As shown, the installation system of the offshore wind power installation vessel of the present invention is arranged in the offshore wind power installation vessel, and the offshore wind power installation vessel includes a hull 1 and a plurality of pile legs 3. The hull 1 is provided with a wind power installation well 2. The installation system includes an installation component 4 and a driving track 5.

[0049] The travel track 5 is arranged on the hull 1, along the length direction of the hull 1, i.e., the X direction. Preferably, the travel track 5 includes a first travel track 50 and a second travel track 51, the second travel track 51 is fixed on the top surface of the hull 1, and the first travel track 50 is suspended above the hull 1 through a vertical support beam.

[0050] The mounting assembly 4 includes a fixed cylinder 40, a first running wheel 41, a second running wheel 42, a third running wheel 43, a connecting shaft 44, an X-direction running drive device 45, a telescopic cylinder 46, a Y-direction adjustment mechanism 47, a mounting platform 48, a Z-direction adjustment mechanism 6 and a rotation adjustment mechanism 7.

[0051] The upper side of the fixed cylinder 40 is connected to the first running wheel 41 through a rotating shaft, and the lower side of the fixed cylinder 40 is connected to the second running wheel 42 and the third running wheel 43 through a rotating shaft. The first running wheel 41 cooperates with the first running track 50, wherein the number and position of the first running track 50 correspond to the number and position of the first running wheel 41; the second running wheel 42 and the third running wheel 43 cooperate with the second running track 51, wherein the number and position of the second running track 51 correspond to the number and position of the second running wheel 42 and the third running wheel 43. Thus, the fixed cylinder 40 is installed on the hull 1 through the first running wheel 41, the second running wheel 42, the third running wheel 43 and the corresponding first running track 50 and the second running track 51.

[0052] As a specific implementation manner, the number of the first travel rail 50 is one, corresponding to one first travel wheel 41 ; the number of the second travel rail 51 is two, corresponding to the second travel wheel 42 and the third travel wheel 43 respectively.

[0053] The connecting shaft 44 is arranged between the second running wheel 42 and the third running wheel 43, and the X-direction running driving device 45 is arranged on the connecting shaft 44. The X-direction running driving device 45 synchronously drives the second running wheel 42 and the third running wheel 43 to move along the length direction of the hull 1, i.e., the X-direction, on the second running track 51 through the connecting shaft 44, thereby driving the fixed cylinder 40 to move accordingly. When the second running wheel 42 and the third running wheel 43 move along the length direction of the hull 1, i.e., the X-direction, on the second running track 51, the first running wheel 41 moves along the first running track 50 accordingly, so as to ensure the movement stability of the fixed cylinder 40.

[0054] The telescopic cylinder 46 is arranged in the fixed cylinder 40, and a Y-direction adjustment mechanism 47 is arranged between the fixed cylinder 40 and one end of the telescopic cylinder 46, and the other end of the telescopic cylinder 46 is connected to the mounting platform 48. Specifically, one end of the Y-direction adjustment mechanism 47 is fixed to the fixed cylinder 40, and the other end of the Y-direction adjustment mechanism 47 is connected to the telescopic cylinder 46, and the Y-direction adjustment mechanism 47 pushes the telescopic cylinder 46 to move in the fixed cylinder 40 along the width direction of the hull 1, i.e., the Y-direction, so as to approach the wind turbine B placed in the middle of the hull 1.

[0055] The Z-direction adjustment mechanism 6 is installed on the mounting platform 48, and a connecting frame 8 is fixed on the Z-direction adjustment mechanism 6. The connecting frame 8 is used to quickly connect the wind turbine B to be installed. The Z-direction adjustment mechanism 6 drives the connecting frame 8 and then drives the wind turbine B to move along the height direction of the hull 1, that is, the Z direction.

[0056] As a specific implementation, the Z-direction adjustment mechanism 6 is composed of a Z-direction adjustment drive device 60 and a lifting rod 61. A Z-direction adjustment drive device 60 is fixed on each side of the mounting platform 48. Each Z-direction adjustment drive device 60 is connected to a lifting rod 61. The lifting rod 61 vertically penetrates the mounting platform 48, and the connecting frame 8 is fixed on the two lifting rods 61. The Z-direction adjustment drive device 60 drives the lifting rod 61 to move along the height direction of the hull 1, i.e., the Z direction, thereby driving the connecting frame 8 to move up and down, thereby driving the wind turbine B connected to the connecting frame 8 to move along the height direction of the hull 1, i.e., the Z direction.

[0057] The rotating adjustment mechanism 7 is installed on the fixed cylinder 40, and the output end of the rotating adjustment mechanism 7 is connected to the telescopic cylinder 46. The rotating adjustment mechanism 7 drives the telescopic cylinder 46 to rotate around the width direction of the hull 1, that is, the Y-axis, thereby driving the mounting platform 48 to rotate, and then through the Z-adjustment mechanism 6 and the connecting frame 8, the wind turbine B is rotated.

[0058] As a specific embodiment, the rotation adjustment mechanism 7 includes a rotation adjustment driving device 70, a rotation driving gear 71 and a gear plate 72. The rotation adjustment driving device 70 is fixed on the fixed cylinder 40, the gear plate 72 is fixed to the outer periphery of the telescopic cylinder 46, one end of the rotation driving gear 71 is connected to the rotation adjustment driving device 70, and the other end of the rotation driving gear 71 is gear-engaged with the gear plate 72. The rotation adjustment driving device 70 drives the rotation driving gear 71, and the rotation driving gear 71 drives the telescopic cylinder 46 to rotate through the gear plate 72.

[0059] In addition, it goes without saying that the driving mechanism and adjustment mechanism involved in this article are not limited to their specific power forms, and can be electric drive, hydraulic drive, or hybrid drive. For example, the X-direction travel drive device 45, the Z-direction adjustment drive device 60 of the Z-direction adjustment mechanism 6, and the rotation adjustment drive device 70 of the rotation adjustment mechanism 7 can all be electric motors or hydraulic motors, and the Y-direction adjustment mechanism 47 can be a cylinder piston group.

[0060] In another aspect of the present invention, an offshore wind power installation vessel is provided, comprising a hull 1 and a plurality of pile legs 3, a wind power installation well 2 is provided on the hull 1, and the above-mentioned installation system is arranged on the offshore wind power installation vessel. Preferably, two sets of installation systems are arranged in the middle of the hull 1, and the two sets of installation systems are arranged symmetrically in the width direction of the hull 1 relative to the wind turbine group B placed in the middle of the hull 1.

[0061] The specific working process of the installation system of the offshore wind power installation vessel and the offshore wind power installation vessel of the present invention is as follows:

[0062] The assembled wind turbine B is fixed vertically on the hull 1 and dragged to the operation point through the hull 1. At this time, the wind turbine installation well 2 set by the hull 1 corresponds to the pre-made offshore wind turbine foundation A, so that the hull 1 can quickly determine the installation position;

[0063] When the installation position is determined, the pile legs 3 are lowered so that the pile legs 3 are supported on the seabed, thereby achieving the purpose of fixing the hull 1;

[0064] Start the X-direction travel drive device 45 to drive the fixing cylinder 40 to move along the length direction of the hull 1, i.e., the X-direction, and move the installation system to the position of the wind turbine B to be installed;

[0065] The Y-direction adjustment mechanism 47 is started to push the telescopic cylinder 46 to move along the width direction of the hull 1, i.e., the Y-direction, so that the connecting frame 8 is quickly connected to the wind turbine B to be installed;

[0066] The X-direction travel drive device 45 is started to drive the wind turbine group B to be installed to move toward the wind turbine installation well 2. After the wind turbine group B to be installed moves to the top of the wind turbine installation well 2, the telescopic cylinder 46 is adjusted by the Y-direction adjustment mechanism 47 and the rotation adjustment mechanism 7 so that the wind turbine group B to be installed is aligned with the offshore wind turbine foundation A.

[0067] The Z-direction adjustment mechanism 6 is started to drive the wind turbine B to be installed to descend along the height direction of the hull 1, i.e., the Z-direction toward the offshore wind power foundation A and complete the docking. After the docking is completed, the connecting frame 8 is separated from the wind turbine B to complete the installation of the wind turbine B.

[0068] Repeat the above steps to install other wind turbines B on the hull 1.

[0069] In summary, compared with the prior art, the installation system of the offshore wind power installation vessel and the offshore wind power installation vessel of the present invention have the following advantages and beneficial effects:

[0070] There is no need to install and use a lattice boom crane on an offshore wind power installation vessel, which significantly increases the usable area and carrying capacity of the installation vessel, increases the number of wind turbines that can be loaded and installed, and can reduce the cost of use and improve installation efficiency;

[0071] The installation system is used to install the wind turbine set, and the cooperation of the X-axis travel drive device, the Y-axis adjustment mechanism, the Z-axis adjustment mechanism, and the rotation adjustment mechanism enables the wind turbine set to be installed quickly, effectively improving the installation efficiency.
