[0044] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed in order to provide a comprehensive understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention. In the drawings and the following description, at least part of the known structures and technologies are not shown in order to avoid unnecessary ambiguity of the present invention; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0045] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the blade maintenance tooling of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0046] like Figure 1As shown, the wind turbine generator set includes a wind turbine foundation, a tower 1, a nacelle 2, a generator 3 and an impeller 4. The tower 1 is connected to the wind turbine foundation, the nacelle 2 is arranged at the top of the tower 1, and the generator 3 is arranged in the nacelle 2. In some examples, the generator 3 can be located outside the nacelle 2. Of course, in some examples, the generator 3 can also be located inside the nacelle 2. The impeller 4 includes a hub 401 and a plurality of blades 402 connected to the hub 401. The impeller 4 is connected to the rotor of the generator 3 through the hub 401, thereby driving the rotor to rotate relative to the stator to achieve the power generation demand of the wind turbine generator set.

[0047] As wind turbines gradually enter the era of parity, the state has cancelled subsidies for grid-connected electricity prices, and domestic complete machine manufacturers are trying to reduce the cost of their units. In order to reduce the cost of units, complete machine manufacturers are innovating technology to increase the capacity of a single unit, so wind turbines are gradually becoming larger. After the parity era, larger megawatt wind turbines have appeared on the market one after another. Correspondingly, the size of wind turbines is getting larger and heavier.

[0048] As the capacity of wind turbine generator sets gradually increases, the height of wind turbine generator sets also gradually increases. Blades 402 are relatively delicate large components of wind turbine generator sets. When the coating or skin on the surface of blades 402 is damaged, it is necessary to repair and maintain the coating or skin as soon as possible. The traditional method for repairing and maintaining blades 402 is that personnel take a hanging basket to perform a series of work in the air. The hanging basket is connected to the anchor point in the cabin 2 by a steel wire rope, and the lifting and lowering of the maintenance personnel and the hanging basket are realized by the retracting and releasing action of the steel wire rope. This method is more suitable for the blades 402 of small megawatt units before, but the height of wind turbine generator sets gradually increases and the blades 402 gradually increase. If the blades 402 of large-capacity units are maintained later, the method of using the aerial hanging basket of personnel is still used. The disadvantage is that the risk of personnel work safety is increasing, and the on-site construction efficiency will also be lower and lower, because the personnel working on the hanging basket are greatly affected by the weather and wind speed, and the difficulty of high-altitude work is gradually increasing as the blades 402 become larger.

[0049] like Figure 2 as well as Figure 3 As shown, based on this, an embodiment of the present application provides a blade 402 maintenance tool, which can be used to support maintenance personnel to the maintenance area of ​​the blade 402 to ensure the safety of the maintenance personnel.

[0050] A blade 402 maintenance tool provided in one embodiment of the present application includes a base 10, an adapter frame 20 and a maintenance assembly 30, wherein the adapter frame 20 is arranged on the base 10, the maintenance assembly 30 is connected to the adapter frame 20, the maintenance assembly 30 extends along a first direction X and includes a maintenance cabin 31, wherein the maintenance assembly 30 has freedom of movement relative to the adapter frame 20 along at least one of the first direction X and a second direction Y intersecting the first direction X.

[0051] When used to maintain the blades 402 of an offshore wind turbine generator set, the base 10 can be connected to the deck 5 of a ship or other component, and when used to maintain an onshore wind turbine generator set, the base 10 can be connected to a vehicle such as a cart or a truck. If the height of the maintenance assembly 30 in the first direction X is high enough, the base 10 can also be placed and fixed on the ground.

[0052] The adapter frame 20 is used to connect the maintenance component 30 to the base 10. The adapter frame 20 and the base 10 can be fixedly connected, that is, the position between the two can remain unchanged. Of course, the adapter frame 20 and the base 10 can also be movably connected, that is, the relative position between the two can also be adjusted.

[0053] The number of the maintenance compartments 31 included in the maintenance component 30 may be one, or more than two. When there are more than two, the more than two maintenance compartments 31 may be distributed along the first direction X.

[0054] The maintenance component 30 can move freely relative to the adapter frame 20 along the first direction X, and can also move freely relative to the adapter frame 20 along the second direction Y. Of course, the maintenance component 30 can also move freely relative to the adapter frame 20 in both the first direction X and the second direction Y.

[0055] Optionally, the angle between the first direction X and the second direction Y may be 90°. For example, when maintaining the blade 402, the first direction X may extend along the length direction or axial direction of the blade 402, and the second direction Y may extend along the thickness direction of the blade 402, or along the arrangement direction of the windward surface and the leeward surface of the blade 402.

[0056] The blade 402 maintenance tool provided in one embodiment of the present application, when the surface of the blade 402 of the wind turbine generator set is damaged, the impeller 4 is first rotated to rotate the damaged blade 402 to a vertical downward state, and then the impeller 4 is locked. Taking the wind turbine generator set as an offshore wind turbine generator set as an example, the base 10 can be connected to the deck 5 of the ship, and the ship carrying the blade 402 maintenance tool can be parked in front of the damaged blade 402. The adapter 20 is used to connect the maintenance component 30 to the base 10 to ensure the installation requirements of the maintenance component 30. Since the maintenance assembly 30 extends along the first direction X, the length of the maintenance assembly 30 can be set as needed according to the height of the area to be maintained of the blade 402 during use, and the setting of the maintenance cabin 31 can provide support and protection for the maintenance personnel, and the maintenance assembly 30 has a degree of freedom of movement relative to the adapter 20 along at least one of the first direction X and the second direction Y intersecting the first direction X, so that the position of the maintenance cabin 31 is adjustable, which is conducive to supporting the maintenance personnel to the area to be maintained of the blade 402, and then the maintenance personnel can perform maintenance when the surface coating, skin, etc. of the blade 402 is damaged. It can effectively avoid the maintenance personnel from working at high altitude in the form of a hanging basket, ensure the safety of the maintenance personnel, and greatly increase the safety, efficiency and convenience of the maintenance work.

[0057] At the same time, the maintenance component 30 is arranged with freedom of movement relative to the adapter frame 20 along at least one of the first direction X and the second direction Y intersecting the first direction X, so that the maintenance tooling can meet the maintenance needs of blades 402 of different models, greatly reducing the operation and maintenance costs of the unit.

[0058] In some optional embodiments, a blade 402 maintenance tool is provided in one embodiment of the present application, and the maintenance assembly 30 includes more than two maintenance cabins 31 , which are distributed along the first direction X, and a climbing component is provided between two adjacent maintenance cabins 31 .

[0059] The number of the maintenance compartments 31 included in the maintenance assembly 30 may be two, three or more, and may be specifically set according to the model of the wind turbine generator set to be maintained and the length of the corresponding blade 402 .

[0060] The climbing component arranged between two adjacent maintenance cabins 31 may include a ladder, a lifting platform, etc.

[0061] The blade 402 maintenance tool provided in one embodiment of the present application has more than two maintenance cabins 31 included in the maintenance assembly 30 and the more than two maintenance cabins 31 are distributed along the first direction X, so that the operator can perform maintenance on the blade 402 in one maintenance cabin 31 and then climb to another maintenance cabin 31 to continue to perform maintenance on the blade 402, thereby ensuring the comprehensiveness of the maintenance of the blade 402. In addition, through the above-mentioned configuration, the blade 402 maintenance tool can also be adapted to the maintenance of blades 402 of different models and different damage height and low position areas, thereby improving the versatility of the blade 402 maintenance tool.

[0062] Optionally, the maintenance cabin 31 may have an opening that is open along the second direction Y, and maintenance personnel can pass through the opening toward the windward side or leeward side of the blade 402, which is conducive to maintaining damaged locations such as surface coating and skin on the surface of the blade 402.

[0063] Optionally, a guardrail may be provided at the opening, the guardrail blocking at least a portion of the opening. By providing the guardrail, the protection of the maintenance personnel can be ensured, and the maintenance personnel can be prevented from falling from the maintenance assembly 30, thereby ensuring the safety of the maintenance personnel.

[0064] In some optional embodiments, an embodiment of the present application provides a blade 402 maintenance tool, wherein the maintenance components 30 are arranged in pairs and symmetrically distributed along the second direction Y, and each maintenance component 30 has freedom of movement in the second direction Y relative to the adapter frame 20.

[0065] The number of pairs of the maintenance components 30 can be one pair, or two pairs or more pairs, and one pair can be selected.

[0066] The cavities of the maintenance components 30 arranged in pairs in the second direction Y can be used to place the blades 402 .

[0067] The maintenance components 30 arranged in pairs can move toward each other or move away from each other.

[0068] The blade 402 maintenance tool provided in the embodiment of the present application arranges the maintenance components 30 in pairs and allows the two to have freedom of movement in the second direction Y relative to the adapter frame 20. When in use, the paired maintenance components 30 can be distributed on both sides of the thickness direction of the blade 402, wherein one maintenance component 30 is arranged opposite to the windward side of the blade 402, and the other maintenance component 30 is arranged opposite to the leeward side of the blade 402. By adjusting the paired maintenance components 30 to move in the second direction Y to adapt to blades 402 of different thicknesses, it is ensured that maintenance personnel can maintain blades 402 of different thicknesses within a suitable distance range, which is beneficial to the maintenance of the blades 402.

[0071] Optionally, the first slide groove 21 may be opened in the first direction X, and the first sliding block 50 may extend into the first slide groove 21 through the opening of the first slide groove 21 in the first direction X and be movably connected to the first slide groove 21 .

[0072] Optionally, the number of the first sliding groove 21 may be one. Of course, the number of the first sliding grooves 21 may be more than two, and the more than two first sliding grooves 21 may be distributed along the first direction X at intervals.

[0073] The number of the first slider 50 provided on the maintenance component 30 may be one, or more than two. When there are more than two, the more than two first sliders 50 may be distributed in the first direction X, and each first slider 50 may be movably connected to one of the first slide grooves 21 .

[0074] The first slider 50 and the first slide groove 21 may be slidably matched, or may be rolled matched. For example, a roller may be provided at the matching position of the first slide groove 21 and the first slider 50 to achieve rolling match between the two.

[0075] The first driving member 40 and the first slider 50 can be connected directly, or indirectly, to achieve the driving of the first slider 50, and then drive the maintenance assembly 30 to reciprocate along the second direction Y relative to the first slide groove 21 through the first slider 50.

[0076] A blade 402 maintenance tool provided by an embodiment of the present application, wherein the blade 402 also includes a first driving member 40, and the adapter frame 20 includes a first slide groove 21, and the maintenance component 30 is provided with a first slider 50 movably connected to the first slide groove 21. The maintenance component 30 can be driven by the first driving member 40 to move in the second direction Y, so that the maintenance component 30 has freedom of movement relative to the adapter frame 20 in the second direction Y, which is beneficial for driving the maintenance personnel to move closer to or away from the surface of the blade 402 along the second direction Y through the maintenance component 30, and when the maintenance components 30 are arranged in pairs, it is beneficial to realize the opening and closing actions between the two maintenance components 30 arranged in pairs, which is suitable for the adaptation requirements of blades 402 with different thicknesses.

[0077] Optionally, the first driving member 40 may include a telescopic member, and the first driving member 40 may be extended or shortened along the second direction Y, so that one of the cylinder body and the cylinder rod of the first driving member 40 is connected to the adapter frame 20, and the other is connected to the first slider 50, and the first slider 50 can be driven to move along the second direction Y by the telescopic movement of the first driving member 40. Through the above arrangement, the first driving member 40 can be directly connected to the first slider 50, and the driving requirements for the first slider 50 and the maintenance assembly 30 connected thereto can be achieved. Optionally, when the first driving member 40 includes a telescopic member and the maintenance assembly 30 is arranged in pairs, the first slider 50 of each maintenance assembly 30 can be respectively connected to the first driving member 40, and the corresponding maintenance assembly 30 can be driven to move by the corresponding first driving member 40.

[0078] It can be understood that the direct connection between the first driving member 40 and the first sliding block 50 is only an optional embodiment.

[0079] In some optional embodiments, a blade 402 maintenance tool provided in one embodiment of the present application may also include a first transmission member 60, which is connected between the first driving member 40 and at least two first sliders 50, so that the first driving member 40 synchronously drives the paired maintenance components 30 to move along the second direction Y toward or away from each other.

[0081] A blade 402 maintenance tool provided by an embodiment of the present application, by setting a first transmission member 60, can use the first transmission member 60 to synchronously transmit the power of the first drive member 40 to at least two first sliders 50, so that the paired maintenance components 30 can be synchronously moved along the second direction Y towards or away from each other, which can realize the opening and closing of the paired maintenance components 30. At the same time, the same first drive member 40 can also be used to synchronously drive the paired maintenance components 30, thereby ensuring the synchronization of the movement of the two, reducing the number of first drive members 40, and reducing the cost of the blade 402 maintenance tool.

[0082] like Figure 4 As shown, in some optional embodiments, a blade 402 maintenance tool is provided in an embodiment of the present application, and the first transmission member 60 includes a first screw rod 61, and the first screw rod 61 includes a first thread and a second thread distributed along the second direction Y, and the rotation directions of the first thread and the second thread are opposite. The first thread is threadedly connected to the first slider 50 connected to one of the paired maintenance components 30, and the second thread is threadedly connected to the first slider 50 connected to the other of the paired maintenance components 30, and one end of the first screw rod 61 is connected to the first driving member 40.

[0083] Both the first thread and the second thread can be spirally wound along the second direction Y for a certain length.

[0084] The first screw rod 61 may be arranged through at least a portion of the first sliding block 50 and be threadedly connected to the corresponding first sliding block 50 .

[0085] The first driving member 40 is used to drive the first screw rod 61 to rotate, thereby driving the first sliding block 50 to move along the second direction Y to drive the maintenance assembly 30 to move.

[0086] In a blade 402 maintenance tool provided in one embodiment of the present application, the first transmission member 60 adopts the above-mentioned structural form, which is conducive to driving the paired maintenance components 30 to move towards or away from each other, and is conducive to meeting the maintenance needs of blades 402 of different thicknesses.

[0087] Optionally, in order to ensure the smooth movement of the maintenance component 30, a guide member can be connected to the maintenance component 30, and the guide member can slide with the adapter frame 20 along the second direction Y, which can not only ensure the smooth movement of the maintenance component 30, but also prevent the maintenance component 30 from rotating, thereby improving the safety performance of the blade 402 maintenance tooling.

[0088] It can be understood that the first transmission member 60 adopting the above-mentioned form is only an optional embodiment.

[0089] like Figure 2 , Figure 3 as well as Figure 5 As shown, in some embodiments, the first transmission member 60 can also include a driving wheel 62, a main shaft 63, and a planetary wheel 64 arranged in pairs, a driven wheel 65, a first shaft 66, a second shaft 67, a first connecting rod 68 and a second connecting rod 69.

[0122] The adapter frame 20 can be movably connected to the base 10 through its bracket body 22 .

[0123] The blade 402 maintenance tool provided in the embodiment of the present application can move the adapter frame 20 relative to the base 10 along the third direction Z as needed through the above-mentioned settings.

[0127] The blade 402 maintenance tool provided in the embodiment of the present application can connect the seat body 11 to the deck 5 of the ship and other equipment when in use. When the blade 402 needs to be maintained, the second drive motor 121 can be used to drive the second screw rod 122 to rotate, and the second screw rod 122 rotates to drive the adapter frame 20 to move along the third direction Z so that at least part of the adapter frame 20 and the maintenance component 30 extend out of the deck 5 of the ship connected to the base 10, so as to achieve the coordination and maintenance of the blade 402. When the maintenance is completed and the tool is no longer needed, the second drive motor 121 can be used to drive the second screw rod 122 to rotate in the opposite direction, so that the adapter frame 20 and its maintenance component 30 move in the opposite direction Z and are recovered into the deck 5, thereby ensuring that when the ship is in operation, collision accidents with the blade 402 maintenance tool are avoided.

[0128] In some optional embodiments, the blade 402 maintenance tool provided in the embodiment of the present application further includes a channel platform 80, which is arranged across the adapter frame 20 and extends from the base 10 to the side where the maintenance assembly 30 is located. By providing the channel platform 80, it is convenient for operators to walk from the deck 5 and other areas to the maintenance assembly 30.

[0129] like Figure 8 as well as Fig. 9 As shown, in some optional embodiments, an embodiment of the present application provides a blade 402 maintenance tool, the maintenance assembly 30 includes a maintenance body and a guide rail 25 extending along a first direction, the guide rail 25 is connected to the adapter frame 20, the maintenance body includes a maintenance cabin 31 and has a guide groove 32 extending along the first direction X, the guide rail 25 at least partially extends into the guide groove 32 and is movably connected to the guide groove 32, the blade 402 maintenance tool also includes a third drive member 70, the third drive member 70 cooperates with the guide rail 25 to drive the maintenance body to move relative to the adapter frame 20 along the first direction X.

[0130] The number of the guide grooves 32 may be the same as the number of the guide rails 25 . When the maintenance components 30 are arranged in pairs, each maintenance component 30 may be provided with at least one guide rail 25 .

[0131] When the maintenance assembly 30 is provided with a first slider 50, the guide rail 25 can be movably connected to the adapter frame 20 through the first slider 50. Optionally, the guide rail 25 can be fixedly connected to the first slider 50, and can be connected in an integrated structure.

[0132] The blade 402 maintenance tool provided in the embodiment of the present application, through the above-mentioned configuration, allows the maintenance body to move along the second direction Y with the maintenance cabin 31, so that the height of the maintenance cabin 31 can be adjusted according to the damaged parts under the surface of the blade 402 at different heights, thereby improving the versatility of the blade 402 maintenance tool and increasing the maintenance coverage of the maintenance tool.

[0133] In some optional embodiments, the third driving member 70 includes a first driving motor 71 and a first gear 72. A rack 251 extending along the first direction X is provided on the side wall of the guide rail 25 in the second direction Y. The first driving motor 71 is provided on the guide rail 25 and connected to the first gear 72. The first gear 72 is meshed with the rack 251.

[0134] The number of the first drive motor 71 included in the third drive member 70 can be one. Of course, the first drive motors 71 included in the third drive member 70 can also be arranged in pairs. The paired first drive motors 71 are symmetrically distributed on both sides of the guide rail 25 in the second direction Y. Correspondingly, racks 251 can be provided on both sides of the guide rail 25 in the second direction Y, and each first drive motor 71 can drive a first gear 72 to engage with the rack 251 for transmission.

[0135] In the blade 402 maintenance tool provided in the embodiment of the present application, the third driving member 70 adopts the above-mentioned structural form and cooperates with the guide rail 25, and the first driving motor 71 can drive the first gear 72 to rotate. Since the first gear 72 is engaged with the rack 251, the maintenance body moves along the first direction X, and the height of the maintenance assembly 30 can be adjusted according to the damaged parts under the surface of the blade 402 at different heights. The versatility of the blade 402 maintenance tool is improved.

[0136] Optionally, a clearance opening can be partially opened on the maintenance body in the second direction Y, so that the rack 251 can be exposed in the clearance opening and mesh with the first gear 72, thereby ensuring the movement requirement of the maintenance body in the first direction X, and providing a limit for the movement of the maintenance body in the first direction X to ensure that it moves within a safe range.

[0137] The blade 402 maintenance tool provided in one embodiment of the present application is mainly used for the maintenance of the surface of the blade 402 when in use. There is no need for personnel to work at high altitudes, and the maintenance of the blade 402 is safer and more efficient. The blade 402 maintenance tool is installed on the deck 5 of the ship. When the tool is used for maintenance work, the fourth drive members 12 on both sides can be synchronized. The second drive motor 121 drives the second screw rod 122 to rotate, which will move the adapter frame 20 and the maintenance component 30 along the third direction Z relative to the seat body 11, and extend the entire adapter frame 20 and the maintenance component 30 outside the deck 5. When the tool is not in normal use, the adapter frame 20 and the maintenance component 30 need to be recovered into the deck 5. Since the nose pitch angle and the cone angle of the blade 402 of machines from different manufacturers are different, the telescopic cylinders 241 included in the second driving members 24 on both sides can be synchronized to allow the mounting frame 23 and the maintenance assembly 30 to rotate around the first pin shaft 236 at the first cross beam 231, so that the maintenance assembly 30 can adapt to the nose pitch angle and the cone angle of the blade 402 of different models.

[0138] Since the thickness of the blade 402 of each model and the thickness of the same blade 402 model in different cross sections are completely different, the first driving member 40 can drive the first transmission member 60, so that the first driving member 40 drives the worm 60b to rotate, and the worm 60b drives the turbine 60a and the two first connecting rods 68 to rotate together with the main shaft 63 as the center, and the main shaft 63 drives the driving wheel 62 to rotate, and the driving wheel 62 is meshed with planetary gears 64 on both sides, and the planetary gears 64 on both sides will rotate with the first shaft 66 as the center, and at the same time, the two first connecting rods 68 are rotated on the first shaft 66. Under the action of a connecting rod 68, the planetary gear 64 and the first shaft 66 will rotate on the tooth surface of the driving wheel 62 with the main shaft 63 as the center. The outer sides of the planetary gears 64 are also meshed with driven wheels 65 respectively. The outer driven wheels 65 will rotate with the center of the second shaft 67. At the same time, under the action of the second connecting rod 69, the second shaft 67 will move the second sliders on both sides along the second direction Y relative to the first slide 21, thereby finally realizing the opening and closing action of the maintenance assembly 30 connected to the guide rail 25 to meet the maintenance of blades 402 of different models. The damaged part of the blade 402 may occur at different surface heights of the blade 402. The first drive motors 71 on both sides can be synchronized to drive the first gear 72 to rotate. The first gear 72 and the rack 251 are meshed, so that the maintenance cabin 31 assembly moves along the first direction X to adjust the height of the maintenance assembly 30, thereby ensuring that the personnel can reach the maintenance height of the damaged part of the blade 402 in the maintenance assembly 30.

[0139] The blade 402 maintenance tool provided in one embodiment of the present application can perform maintenance work on the blade 402 without the need for personnel to perform high-altitude operations, which greatly increases the safety of the maintenance work on the blade 402. The blade 402 maintenance tool is easy to use. Since there are no personnel working at high altitudes, the maintenance work is greatly reduced by the influence of weather and wind speed, and the maintenance operation window period on site is increased, so that the maintenance work on the blade 402 becomes more efficient and convenient. The blade 402 maintenance tool can meet the maintenance of blades 402 of units of different models, and has strong versatility. Through the various adjustment mechanisms inside the tool, the blades 402 of units of different models and different cross-sectional positions of the same blade 402 can be maintained without modifying the tool, which greatly improves the utilization rate of the tool and reduces the cost of tool modification.
