[0002] With the rapid development of offshore wind power technology in my country, the scale and installed capacity of offshore wind farms are getting larger and larger. The operation and maintenance work of offshore wind farms is becoming more and more heavy, and maintenance personnel are required to take operation and maintenance ships to the site for maintenance.

[0003] The tower of an offshore wind turbine is erected on the sea surface through multiple pile legs. Due to the effects of wind, waves and currents, there is a relative displacement between the maintenance ship and the wind turbine pile legs. In addition, the swaying and heaving of the ship body make it difficult for maintenance personnel to steadily climb onto the wind turbine tower. There is also a risk of falling or being squeezed by the ship body. In the related art, a clamping device is set on the bow or side of the hull of the maintenance ship. When the maintenance ship is leaning against the pile legs, the personnel clamp the pile legs by operating the clamping device to make the maintenance ship relatively fixed so that the maintenance personnel can climb onto the tower.

[0056] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of methods and devices consistent with some aspects of the utility model as detailed in the attached claims.

[0057] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0058] As mentioned in the background technology section, in the related technology, a manual clamping device is set on the bow or hull side of the operation and maintenance vessel, and the pile legs are clamped by manually operating the clamping device. Due to the influence of wind and waves, it is not easy to clamp the pile legs accurately and stably, which is time-consuming and labor-intensive and inconvenient for maintenance climbing the tower.

[0059] In view of the above-mentioned problems existing in the prior art, the utility model provides a docking device and an offshore wind power operation and maintenance system. The docking device provided by the utility model includes a device body, at least two clamping members, a transmission mechanism and a trigger mechanism. The device body is connected to the offshore wind power operation and maintenance ship by setting the device body, and the two clamping members are relatively rotated and set on the device body, and the two clamping members are connected by a transmission mechanism. Among them, the trigger mechanism includes a trigger member and at least one connecting component, and the trigger member is set on the device body, and the trigger member is connected to the transmission mechanism through the connecting component. When the device body on the offshore wind power operation and maintenance ship squeezes the trigger member on the pile leg so that the trigger member produces a predetermined elastic deformation, the trigger member drives the two clamping members to rotate relative to each other through the connecting component and the transmission mechanism to clamp the pile leg. That is, the two clamping members are triggered to rotate relative to each other by squeezing the pile leg by the trigger member, and the pile leg is clamped accurately and stably, so that the hull remains basically stable, which is convenient for maintenance personnel to climb the tower.

[0060] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the utility model in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0061] First, please refer to Figures 1 to 5 As shown, the docking device provided in this embodiment is used for an offshore wind power operation and maintenance ship to dock beside the pile leg 10 of an offshore wind turbine generator set. The docking device includes a device body 100, at least two clamping members 200, a transmission mechanism 300 and a trigger mechanism 400. The device body 100 is used to connect with the offshore wind power operation and maintenance ship, and the two clamping members 200 are relatively rotatably arranged on the device body 100, and the two clamping members 200 are connected by a transmission mechanism 300.

[0062] The trigger mechanism 400 includes a trigger member 410 and at least one connecting assembly 420. The trigger member 410 is disposed on the device body 100, and the trigger member 410 is connected to the transmission mechanism 300 through the connecting assembly 420. The trigger mechanism 400 is configured such that when the device body 100 presses the trigger member 410 on the pile leg 10 so that the trigger member 410 generates a predetermined elastic deformation, the trigger member 410 drives the two clamping members 200 to rotate relative to each other through the connecting assembly 420 and the transmission mechanism 300 to clamp the pile leg 10.

[0063] In this embodiment, the offshore wind turbine can be erected on the sea surface by a plurality of pile legs 10, and the offshore wind turbine operation and maintenance ship is at least docked beside one of the pile legs 10 to keep the ship relatively stable, so as to facilitate maintenance personnel to climb the tower.

[0064] The device body 100 is used to provide an installation basis for the clamping member 200, the transmission mechanism 300 and the trigger mechanism 400. It can be a separate frame-shaped, block-shaped, shell-shaped or other structure. The device body 100 can be connected to the bow, hull and other positions of the offshore wind power operation and maintenance vessel by screwing, welding, clamping and other methods. The device body 100 can also be a part of the hull, such as part of the bow, part of the hull, etc.

[0065] The clamping member 200 is used to clamp the peripheral wall of the pile leg 10. It can be a plate-shaped, frame-shaped structure, etc. The two clamping members 200 are arranged opposite to each other. The adjacent sides of the two clamping members 200 can be provided with clamping grooves, clamping protrusions, etc. that match the peripheral wall of part of the pile leg 10, which can be determined according to the shape of the peripheral wall of a specific part of the pile leg 10.

[0066] The clamping members 200 can be rotatably connected to the device body 100 via a rotating structure such as a rotating shaft and a bearing, and the rotation axes of the two are arranged vertically so that when the two clamping members 200 rotate in a direction approaching each other, the pile leg 10 can be clamped, and when the two clamping members 200 rotate in a direction away from each other, the pile leg 10 can be loosened.

[0067] The transmission mechanism 300 is used to drive the two clamping members 200 to rotate relative to each other under the action of the trigger mechanism 400. It can be a transmission mechanism composed of a connecting rod and a rack and pinion, etc., which can be determined according to the specific structure of the trigger mechanism 400.

[0068] The trigger member 410 is used to drive the two clamping members 200 to rotate through the transmission mechanism 300 while being squeezed and deformed with the pile leg 10. The trigger member 410 can be a member with a certain elasticity made of rubber, silicone, etc. The trigger member 410 can be connected to the device body 100 by screwing, clamping, riveting, etc. The trigger member 410 has at least a part of the area that can be squeezed with the pile leg 10 and deformed inwardly, and when the trigger member 410 is separated from the pile leg 10, the area returns to its original state.

[0069] The connecting component 420 is used to transmit the deformation movement of the trigger member 410 under extrusion to the transmission mechanism 300. It can be a connecting rod, a connecting plate and other components. One side of the connecting component 420 is connected to the trigger member 410, and the other side of the connecting component 420 is connected to the transmission mechanism 300, so that as the trigger member 410 is squeezed and deformed, the two clamping members 200 are driven to rotate relative to each other through the connecting component 420 and the transmission mechanism 300.

[0070] Specifically, the device body 100 can be fixed to the bow or the side of the hull of the offshore wind power operation and maintenance ship. When the operation and maintenance ship approaches the pile leg 10, the trigger member 410 is pressed against the pile leg 10 by the device body 100. The pressing direction is as follows: Figure 2 As shown in the Y-axis direction, when the trigger member 410 generates a predetermined elastic deformation, the trigger member 410 drives the two clamping members 200 to rotate relative to each other through the connecting assembly 420 and the transmission mechanism 300 to clamp the pile leg 10, as shown in FIG. Figure 5 shown.

[0071] The predetermined elastic deformation, i.e., the deformation degree of the trigger member 410 , may be determined according to the transmission structure of the transmission mechanism 300 and actual requirements. For example, the predetermined elastic deformation may be one quarter of the circumference of the pile leg 10 , which can drive the two clamping members 200 to clamp the pile leg 10 .

[0072] It can be understood that, compared with clamping the pile legs by manually operating the clamping device, the docking device provided in this embodiment triggers the two clamping members 200 to rotate relative to each other by squeezing the pile legs 10 by the trigger member 410, thereby accurately and stably clamping the pile legs 10, so that the hull remains basically stable, making it easier for maintenance personnel to climb the tower.

[0073] It should be noted that after the two clamps 200 clamp the pile leg 10, on the one hand, the operator can use a limiting tool to limit the loosening of the two clamps 200, and on the other hand, the maintenance vessel can tighten the pile leg 10 to ensure that the two clamps 200 continue to clamp.

[0074] It is worth noting that the elastic deformation of the trigger member 410 is used to buffer the impact between the device body 100 and the pile leg 10, and the two clamping members 200 are used to clamp the pile leg 10, thereby alleviating the rigid impact and ensuring the relative stability between the hull and the pile leg 10.

[0075] Therefore, the docking device provided by the utility model includes a device body 100, at least two clamping members 200, a transmission mechanism 300 and a trigger mechanism 400. The device body 100 is connected to the offshore wind power operation and maintenance ship, and the two clamping members 200 are relatively rotated and arranged on the device body 100, and the two clamping members 200 are connected through the transmission mechanism 300. Among them, the trigger mechanism 400 includes a trigger member 410 and at least one connecting component 420, and the trigger member 410 is arranged on the device body 100, and the trigger member 410 is connected to the transmission mechanism 300 through the connecting component 420. When the device body 100 on the offshore wind power operation and maintenance ship squeezes the trigger member 410 on the pile leg 10 so that the trigger member 410 generates a predetermined elastic deformation, the trigger member 410 drives the two clamping members 200 to rotate relatively through the connecting component 420 and the transmission mechanism 300 to clamp the pile leg 10. That is, the triggering member 410 squeezes the pile leg 10 to trigger the two clamping members 200 to rotate relative to each other, thereby accurately and stably clamping the pile leg 10, so that the hull remains basically stable, making it easier for maintenance personnel to climb the tower.

[0076] In a possible design, the connecting assembly 420 includes a first connecting member 421, a second connecting member 422 and a first elastic member 423, one side of the first connecting member 421 is connected to the trigger member 410, and the other side of the first connecting member 421 is rotatably connected to the second connecting member 422. The second connecting member 422 is movably disposed on the device body 100 along the first direction and is connected to the transmission mechanism 300.

[0077] The first elastic member 423 is disposed on the device body 100 and connected to the second connecting member 422. The first elastic member 423 is configured to elastically press the trigger member 410 in the direction of restoring deformation through the second connecting member 422 and the first connecting member 421.

[0078] Specifically, the first connecting member 421 and the second connecting member 422 are used to transmit movement as the trigger member 410 is deformed. They can be rod-shaped, plate-shaped, block-shaped or other structures. One side of the first connecting member 421 can be rotatably connected to the trigger member 410 through a hinge, a rotating shaft, etc., and the other side of the first connecting member 421 can also be rotatably connected to the second connecting member 422 through a hinge, a rotating shaft, etc.

[0079] The second connecting member 422 can be movably arranged on the device body 100 through a guide structure such as a guide rail or a guide rod. The second connecting member 422 moves along a first direction, which is arranged in a horizontal direction and is perpendicular to the extrusion direction, such as along Figure 2 The X-axis direction is shown.

[0080] The first elastic member 423 is used to assist the trigger member 410 to recover through the first connecting member 421 and the second connecting member 422 . The first elastic member 423 may be an elastic member such as a compression spring. The first elastic member 423 is arranged along the first direction, with one side connected to the device body 100 and the other side abutting against the second connecting member 422 .

[0081] In this way, if Figure 2 , Figure 3 As shown, the first elastic member 423 elastically presses the trigger member 410 in the direction of restoring deformation through the second connecting member 422 and the first connecting member 421. When the trigger member 410 is squeezed with the pile leg 10, the pressing force of the trigger member 410 on the pile leg 10 can be increased. When the trigger member 410 is separated from the pile leg 10, the trigger member 410 can be quickly restored.

[0082] The specific shapes, size parameters, etc. of the first connecting member 421 , the second connecting member 422 and the first elastic member 423 may be determined according to actual needs and are not specifically limited in this embodiment.

[0083] Furthermore, in this embodiment, the trigger member 410 has an elastic deformation portion 411 , and there are two connecting components 420 . The two connecting components 420 are arranged oppositely on both sides of the elastic deformation portion 411 , and the two first connecting components 421 are both connected to the elastic deformation portion 411 .

[0084] Specifically, Figure 2 , Figure 3 As shown, the elastic deformation portion 411 is an area in the middle of the head end of the trigger member 410, and the deformation of this area can be greater than that of other areas on the trigger member 410. The two connecting components 420 can be arranged on both sides of the elastic deformation portion 411 relatively along the first direction, and the two first connecting members 421 are both connected to the elastic deformation portion 411.

[0085] In this way, when the elastic deformation part 411 is not completely aligned with the pile leg 10 and most of the extrusion force falls on only one of the connecting components 420, the transmission mechanism 300 will drive the other connecting component 420 to move and stretch the elastic deformation part 411, so that the deformation part of the elastic deformation part 411 is offset toward the middle, so that the pile leg 10 is roughly located in the middle position between the two clamping members 200, which is convenient for clamping.

[0086] In some embodiments, a guide member 110 is disposed on the device body 100 along the first direction, the second connecting member 422 is slidably connected to the guide member 110 , and the first elastic member 423 is sleeved on the guide member 110 .

[0087] For example, Figure 2 , Figure 3 As shown, the guide member 110 is used to guide the second connecting member 422, which can be a guide rod, a guide rail, etc. The guide member 110 is arranged along the first direction and connected to the device body 100. The second connecting member 422 can be slidably connected to the guide member 110 through a guide sleeve, a guide groove, etc., and the first elastic member 423 is sleeved on the guide member 110.

[0088] This arrangement can ensure stable movement of the second connecting member 422 and the first elastic member 423. Of course, the guide member 110 can also be replaced by other structures, components, etc. with a guiding function, which can be determined according to actual needs and is not specifically limited in this embodiment.

[0089] In order to ensure that the two clamping members 200 remain in a clamped state when docking, the present embodiment further includes a limit assembly 500 disposed on the device body 100. The limit assembly 500 is configured such that when the two clamping members 200 clamp the pile leg 10, the trigger member 410 drives the second connecting member 422 to move to a predetermined position via the first connecting member 421. The limit assembly 500 is connected to the second connecting member 422 to limit the movement of the second connecting member 422.

[0090] In this way, when the two clamping members 200 clamp the pile leg 10, the second connecting member 422 is limited to move by the limiting assembly 500, thereby limiting the rotation of the two clamping members 200 and maintaining the clamping state. When the connection between the limiting assembly 500 and the second connecting member 422 is released, the clamping state of the two clamping members 200 is released.

[0091] Exemplarily, in this embodiment, the position limiting assembly 500 includes a position limiting member 510, which is movably arranged at a predetermined position on the device body 100. The position limiting member 510 has a first plug-in portion 511 on one side facing the second connecting member 422, and the second connecting member 422 is provided with a second plug-in portion 4221 matching the first plug-in portion 511. The position limiting member 510 is configured to move under the action of gravity to plug the first plug-in portion 511 with the second plug-in portion 4221 when the second connecting member 422 is at a predetermined position.

[0092] Specifically, combined Figure 2 , Figure 4As shown, the limit member 510 can be a rod-shaped, plate-shaped or other structure. The limit member 510 can be movably connected to the device body 100 through a guide hole, a guide rail or the like, and is located at a predetermined position. It moves in the vertical direction. The lower end of the limit member 510 has a first plug-in portion 511, and the first plug-in portion 511 can be a plug. The second plug-in portion 4221 on the second connecting member 422 can be a socket matching the plug. When the second connecting member 422 moves to the predetermined position, the limit member 510 moves under the action of gravity to insert the plug into the socket, thereby locking the second connecting member 422.

[0093] It should be noted that, in order to avoid interference caused by the free downward movement of the stopper 510 before the second connector 422 reaches the predetermined position, on the one hand, the upper surface of the second connector 422 can be long enough so that the lower end of the stopper 510 always contacts the upper surface of the second connector 422 before the second connector 422 reaches the predetermined position, and when the second connector 422 moves to the predetermined position, the stopper 510 moves downward again to perform insertion and limiting. On the other hand, a guiding inclined surface can be provided at the lower end of the stopper 510 or on the second connector 422, respectively, so that when the second connector 422 contacts the stopper 510, under the action of the guiding inclined surface, the lower end of the stopper 510 can smoothly transition to the second connector 422 without getting stuck.

[0094] Of course, the first plug-in portion 511 and the second plug-in portion 4221 may also be replaced by other plug-in structures, any plug-in structure that can play a limiting role and does not cause interference before the second connecting member 422 reaches a predetermined position, and is not specifically limited in this embodiment.

[0095] Furthermore, in this embodiment, the limiting assembly 500 further includes a second elastic member 520 , which is sleeved on the limiting member 510 and elastically presses the limiting member 510 toward the direction close to the second connecting member 422 .

[0096] Specifically, Figure 4 As shown, the second elastic member 520 is used to increase the plug-in force of the limit member 510, and it can be an elastic member such as a compression spring. The second elastic member 520 can be sleeved on the limit member 510, and the upper end of the second elastic member 520 is tightly pressed against the device body 100, and the lower end of the second elastic member 520 is tightly pressed against the limit member 510 to maintain the stability of the plug-in of the limit member 510 and prevent it from loosening.

[0097] Of course, the second elastic member 520 may also be replaced by other mechanisms that can increase the limiting force of the limiting member 510 on the second connecting member 422 , depending on actual needs, and is not excessively limited in this embodiment.

[0098] In order to achieve stable transmission, in this embodiment, the transmission mechanism 300 includes two rotating members 310, at least one first transmission member 320 and at least one second transmission member 330. The two rotating members 310 are synchronously rotated and connected, and the rotation directions are opposite. The two rotating members 310 are correspondingly coaxially connected to the two clamping members 200.

[0099] The first transmission member 320 is in transmission connection with one of the rotating members 310, one side of the second transmission member 330 is connected to the second connecting member 422, and the other side of the second transmission member 330 is in transmission connection with the first transmission member 320. The transmission mechanism 300 is configured to drive the second transmission member 330 to move through the second connecting member 422, so as to drive the first transmission member 320 to rotate, thereby driving the two rotating members 310 to rotate relative to each other.

[0100] Specifically, if Figure 2 As shown, the two rotating members 310 can be two synchronous gears of the same model, and the two synchronous gears are coaxially connected to the two clamping members 200 and mesh with each other so that the two clamping members 200 can rotate synchronously in opposite directions. The first transmission member 320 can be a transmission gear, which is coaxially connected to one of the synchronous gears. The second transmission member 330 can be a transmission rack matching the transmission gear, and the transmission rack is arranged along the first direction. One side of the transmission rack is fixedly connected to the second connecting member 422 so as to move therewith, and the other side of the transmission rack is meshed with the transmission gear.

[0101] In this way, when the second connecting member 422 moves, it drives the transmission rack to move, thereby driving the transmission gear to rotate, and then driving the two synchronous gears to rotate synchronously in the opposite direction, so as to achieve synchronous and opposite rotation of the two clamping members 200. The specific models of the gears and racks can be determined according to actual needs.

[0102] Of course, the transmission mechanism 300 may also be replaced by other types of transmission mechanisms, such as a multi-link mechanism, etc. Any mechanism that can drive the two clamping members 200 to rotate synchronously in opposite directions is acceptable, and this embodiment does not impose too many restrictions.

[0103] In order to achieve stable clamping, in this embodiment, clamping portions 210 matching with the peripheral wall of part of the pile leg 10 are respectively provided on opposite sides of the two clamping members 200 , and the two clamping portions 210 are used to clamp opposite sides of the pile leg 10 .

[0104] For example, Figure 2 As shown, the adjacent sides of the two clamping members 200 are provided with clamping grooves matching the peripheral wall of part of the pile leg 10 . The two clamping grooves can enclose a circular hole, an elliptical hole, a square hole, etc., which depends on the shape of the peripheral wall of the pile leg 10 .

[0105] It should be noted that the two clamping parts 210 should reserve a gap required for the deformation of the trigger member 410 , which can be determined according to the actual elasticity and deformation amount of the trigger member 410 , and this embodiment does not limit this.

[0106] In a second aspect, an embodiment of the utility model further provides an offshore wind power operation and maintenance system, comprising a hull and a docking device provided in any of the above embodiments, wherein the hull is provided with a docking device.

[0107] Among them, the docking device has been described in detail in the above embodiments and will not be described in detail here.

[0108] It is understandable that the device body on the docking device can be fixedly connected to the bow, the side of the hull, etc. by screwing, welding, clamping, etc., and the device body can also be integrally formed with the hull. The specific connection method and position of the device body and the hull can be determined according to actual needs and are not specifically limited in this embodiment.

[0109] The offshore wind power operation and maintenance system provided by the embodiment of the utility model is provided with a docking device, which includes a device body 100, at least two clamping members 200, a transmission mechanism 300 and a trigger mechanism 400. The device body 100 is connected to the offshore wind power operation and maintenance ship, and the two clamping members 200 are relatively rotated and arranged on the device body 100, and the two clamping members 200 are connected through the transmission mechanism 300. Among them, the trigger mechanism 400 includes a trigger member 410 and at least one connecting component 420, and the trigger member 410 is arranged on the device body 100, and the trigger member 410 is connected to the transmission mechanism 300 through the connecting component 420. When the device body 100 on the offshore wind power operation and maintenance ship squeezes the trigger member 410 on the pile leg 10 so that the trigger member 410 generates a predetermined elastic deformation, the trigger member 410 drives the two clamping members 200 to rotate relatively through the connecting component 420 and the transmission mechanism 300 to clamp the pile leg 10. That is, the triggering member 410 squeezes the pile leg 10 to trigger the two clamping members 200 to rotate relative to each other, thereby accurately and stably clamping the pile leg 10, so that the hull remains basically stable, making it easier for maintenance personnel to climb the tower.
