[0022] See also Figure 1-7 As shown, the present invention provides a technical solution for an improved mechanical mooring device for offshore wind power maintenance vessels: An improved mechanical mooring device for an offshore wind power maintenance vessel comprises a support frame 12 located on one side of an offshore wind power maintenance vessel 11, a support groove 13 is vertically opened on the support frame 12, a connecting rod 14, a slider and an abutment 2 are installed in the support groove 13, the end of the horizontally arranged connecting rod 14 is fixedly connected to the side wall of the support groove 13, a connecting groove 15 is horizontally opened on the side wall of the connecting rod 14, there are two horizontally arranged connecting blocks 16, and the two connecting blocks 16 are respectively located on both sides of the connecting rod 14, each connecting block 16 is sleeved on the connecting rod 14 and is slidably connected to the connecting rod 14.

[0023] There are two abutment members 2, and the two abutment members 2 correspond one-to-one to the two connecting blocks 16. Each abutment member 2 includes an abutment block 23, an abutment spring 22 and an abutment plate 21. The horizontally arranged abutment block 23 is located on one side of the connecting block 16, and the top of the abutment block 23 is fixedly connected to the connecting block 16, the bottom of the abutment block 23 extends into the connecting groove 15 and is slidably connected to the side wall of the connecting groove 15, the horizontally arranged abutment spring 22 is located on the other side of the connecting block 16, and the abutment spring 22 is sleeved on the connecting rod 14, one end of the abutment spring 22 is fixedly connected to the side wall of the support groove 13, and the other end of the abutment spring 22 is fixedly connected to the side wall of the connecting block 16. The horizontally arranged abutment plate 21 is arc-shaped, and the concave arc side of the abutment plate 21 opens toward the wind turbine 1. An elastic block 37 is installed on the side wall of the abutment plate 21. The elastic block 37 is made of rubber material. One side of the elastic block 37 is bonded to the side wall of the abutment plate 21, and the other side of the elastic block 37 contacts the side wall of the wind turbine 1.

[0024] When the staff transfers the offshore wind power maintenance ship 11, the elastic block 37 on the abutment plate 21 abuts against the side wall of the wind turbine group 1. At the same time, through the elastic potential energy of the abutment spring 22, the connecting block 16 drives the abutment plate 21 to move along the axial direction of the connecting rod 14 until the side wall of the abutment plate 21 abuts against the side wall of the wind turbine group 1, thereby buffering the support frame 12 and the wind turbine group 1, so that the support frame 12 is not easy to shake with the wind turbine group 1, thereby protecting the crane and electrical system and other equipment on the offshore wind power maintenance ship 11, extending the service life of the equipment, and facilitating the staff to perform maintenance operations.

[0025] In order to further improve the stability between the wind turbine set 1 and the support frame 12, an abutment groove 31 is horizontally opened on the side of the abutment plate 21 close to the wind turbine set 1. A driving member 5, a screw rod 41, a limit rod 43 and a limit plate 44 are installed on the support frame 12. The driving member 5 includes a driving motor 51, a driving wheel 52 and a driven wheel 53. The driving motor 51 is located on the side wall of the support frame 12 and is fixedly connected to the side wall of the support frame 12.

The vertically arranged driving wheel 52 is located on the side wall of the support frame 12 and is rotatably connected to the support frame 12. The vertically arranged driven wheel 53 is located on one side of the driving wheel 52, and the driven wheel 53 is rotatably connected to the support frame 12. The driven wheel 53 is meshed with the driving wheel 52. The horizontally arranged screw rod 41 is threadedly penetrated by the driven wheel 5 3 and the side wall of the support frame 12 extend into the support groove 13, and the end of the screw rod 41 is not connected to the side wall, and a limiting groove 42 is coaxially provided at one end of the screw rod 41 close to the wind turbine group 1, one end of the limiting rod 43 extends into the limiting groove 42 and is slidably connected to the side wall of the limiting groove 42, and the other end of the limiting rod 43 passes through the abutment plate 21 and is connected to the side wall of the limiting plate 44, and a damping layer 45 is provided on the end of the limiting rod 43 away from the screw rod 41, one side of the damping layer 45 is bonded to the end of the limiting rod 43, and the other side of the damping layer 45 is slidably connected to the side wall of the limiting groove 42, through the damping layer 45, part of the kinetic energy generated when the abutment plate 21 shakes is converted into internal energy between the damping layer 45 and the side wall of the limiting groove 42, thereby further reducing the shaking between the offshore wind power maintenance vessel 11 and the wind turbine group 1. The horizontally arranged limiting plate 44 is located in the abutting groove 31 and is slidably connected to the side wall of the abutting groove 31 . The other side of the limiting plate 44 is used to abut against the side wall of the wind turbine 1 .

[0026] A connecting plate 71, a baffle 73 and a transverse plate 74 are installed on the side wall of the support groove 13. The side wall of the horizontally arranged connecting plate 71 is fixedly connected to the side wall of the support groove 13. A transverse groove 72 is horizontally opened on the side of the connecting plate 71 close to the wind turbine generator set 1. The baffle 73 is located in the transverse groove 72 and is slidably connected to the side wall of the transverse groove 72. A ball 75 is installed on the baffle 73. One side of the ball 75 is rotatably connected to the side wall of the baffle 73, and the other side of the ball 75 is rotatably connected to the side wall of the transverse groove 72. The transverse plate 74 is located on the side of the baffle 73 close to the wind turbine generator set 1. One side of the transverse plate 74 extends into the transverse groove 72 and is fixedly connected to the side wall of the baffle 73. The other side of the transverse plate 74 is fixedly connected to the side wall of the abutment plate 21.

[0027] When the staff abuts the limit position of the wind turbine 1, the staff starts the drive motor 51, and the output shaft of the drive motor 51 rotates to drive the active wheel 52 to rotate synchronously, thereby driving the driven wheel 53 to rotate synchronously, and the rotation of the driven wheel 53 drives the screw 41 to rotate synchronously, thereby adjusting the distance between the screw 41 and the side wall of the abutment plate 21 until the end of the screw 41 abuts against the side wall of the abutment plate 21, so that the side wall of the concave arc side of the abutment plate 21 abuts against the wind turbine 1, thereby further reducing the shaking of the wind turbine 1 and the offshore wind power maintenance vessel 11, improving stability, and protecting the equipment of the offshore wind power maintenance vessel 11. When the staff completes the maintenance of the wind turbine set 1, the staff adjusts the drive motor 51 so that the output shaft direction of the drive motor 51 rotates, thereby causing the abutment plate 21 to move along the side away from the wind turbine set 1, thereby adjusting the distance between the cross plate 74 and the connecting plate 71 until the baffle 73 on the cross plate 74 abuts against the transverse groove 72 on the connecting plate 71. At this time, the end of the limit rod 43 is still in the limit groove 42 on the screw rod 41, thereby limiting the limit rod 43, making it difficult for the limit rod 43 to disengage from the limit groove 42, thereby improving safety.

[0028] A transmission groove 32 is horizontally opened at the end of each abutment plate 21, and a transmission spring 33 and a transmission plate 34 are installed in the transmission groove 32. One end of the horizontally arranged transmission spring 33 is fixedly connected to the side wall of the transmission groove 32, and the other end of the transmission spring 33 is fixedly connected to the side wall of the transmission plate 34. One end of the horizontally arranged transmission plate 34 extends into the transmission groove 32 and is slidably connected to the side wall of the transmission groove 32, and the other end of the transmission plate 34 extends out of the transmission groove 32. A vertical groove 35 is vertically opened at the bottom of the transmission plate 34, and there are multiple vertical grooves 35, and the multiple vertical grooves 35 are distributed along the length direction of the transmission plate 34. A lifting cylinder 36 is installed at the bottom of the abutment plate 21. The cylinder body of the lifting cylinder 36 is fixedly connected to the bottom of the abutment plate 21, and the piston rod of the lifting cylinder 36 is vertically arranged upward, and the piston rod of the lifting cylinder 36 is plugged into the set vertical groove 35, so as to limit the transmission plate 34.

[0029] A rotating rod 61, a rotating plate 62 and a rotating cylinder 63 are installed on the transmission plate 34. The bottom of the vertically arranged rotating rod 61 is fixedly connected to the top of the transmission plate 34. The horizontally arranged rotating plate 62 is sleeved on the rotating rod 61 and is rotatably connected to the rotating rod 61. The side wall of the rotating plate 62 abuts against the side wall of the wind turbine set 1. The rotating cylinder 63 is located on the transmission plate 34. The cylinder body of the rotating cylinder 63 is fixedly connected to the top of the transmission plate 34. The piston rod of the rotating cylinder 63 abuts against the side wall of the rotating plate 62.

[0030] When the wind turbine 1 abuts against the abutment plate 21 to a limit position, the transmission plate 34 moves along the length direction of the transmission slot 32 through the elastic potential energy of the transmission spring 33, until the transmission plate 34 is transmitted to the set position, the staff adjusts the lifting cylinder 36, and the piston rod of the lifting cylinder 36 is lifted and lowered, so that the piston rod of the lifting cylinder 36 is plugged into the vertical slot 35, thereby improving the stability of the transmission plate 34. At the same time, the staff adjusts the rotating cylinder 63, and the piston rod of the rotating cylinder 63 is extended and retracted to drive the rotating plate 62 to move synchronously. Through the rotating rod 61, the side wall of the rotating plate 62 abuts against the side wall of the wind turbine 1, further improving the stability of the abutment plate 21 and the wind turbine 1, reducing the shaking between the offshore wind power maintenance vessel 11 and the wind motor, and improving safety.

[0031] The working principle of the present invention is as follows: When the improved offshore wind power maintenance vessel mechanical mooring device of the present embodiment is in use, after the offshore wind power maintenance vessel 11 is transferred to the set position, the elastic block 37 on the abutment plate 21 abuts against the side wall of the wind turbine group 1, and through the elastic potential energy of the abutment spring 22, the connection block 16 drives the abutment plate 21 to move along the axial direction of the connecting rod 14 until the side wall of the abutment plate 21 abuts against the side wall of the wind turbine group 1. At the same time, the staff starts the drive motor 51, and the output shaft of the drive motor 51 rotates to drive the driving wheel 52 to rotate synchronously, thereby driving the driven wheel 53 to rotate synchronously, and the driven wheel 53 rotates to drive the screw 41 to move synchronously until the screw 41 is The end portion abuts against the side wall of the abutment plate 21, so that the side wall of the abutment plate 21 abuts against the side wall of the wind turbine 1. Through the elastic potential energy of the transmission spring 33, the transmission plate 34 moves along the length direction of the transmission slot 32. When the transmission plate 34 is transmitted to the set position, the staff starts the lifting cylinder 36, and the piston rod of the lifting cylinder 36 is extended and retracted, so that the piston rod of the lifting cylinder 36 is plugged into the vertical slot 35, thereby improving the stability of the transmission plate 34. At the same time, the staff starts the rotating cylinder 63, and the piston rod of the rotating cylinder 63 is extended and retracted to drive the rotating plate 62 to move. Through the rotating rod 61, the side wall of the rotating plate 62 abuts against the side wall of the wind turbine 1.

[0032] By abutting the elastic potential energy of the spring 22 and the elastic block 37, the support frame 12 and the wind turbine 1 are buffered, the stability of the support frame 12 and the wind turbine 1 is improved, and the support frame 12 is not easy to shake with the wind turbine 1, thereby protecting the crane and electrical system and other equipment on the offshore wind power maintenance ship 11, extending the service life of the equipment, and facilitating maintenance operations for staff. At the same time, the screw 41 abuts against the abutment block 23, so that the abutment block 23 abuts against the side wall of the wind turbine 1, and by rotating the cylinder 63, the side wall of the rotating plate 62 abuts against the side wall of the wind turbine 1, further improving the stability between the support frame 12 and the wind turbine 1, further protecting the equipment on the offshore wind power maintenance ship 11, extending the service life of the equipment on the offshore wind power maintenance ship 11, and facilitating subsequent operations for staff.
