[0039] 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.

[0040] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the assembly 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 ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0041] As wind turbines have entered the era of parity, the state has cancelled subsidies for grid-connected electricity prices, and domestic equipment manufacturers are trying to reduce the cost of their equipment. In order to reduce the cost of equipment, all equipment manufacturers are innovating technology to increase the capacity of a single unit, so domestic wind turbines are gradually developing towards large capacity. After the parity era, 8MW, 11MW, 12MW, 13MW and even 16MW large megawatt units have appeared on the market, and the size of the units is getting bigger and heavier.

[0042] At the same time, as the offshore project areas are gradually developed and saturated, offshore wind power projects are gradually developing towards the deep sea. The project operating water depth will develop from 20m, 30m to 50m, 70m or even 100m. For offshore wind turbines in the deep sea, floating foundations will be used as the foundation form. Floating foundations are much higher than fixed foundations in terms of economy and construction difficulty.

[0043] At present, the construction process of floating units is mainly to assemble the wind turbines onto the floating foundation by crane at the dock, and then transport them to the machine site by wet dragging. Due to the high weight and height of affordable large-capacity units, there are currently no larger and more suitable cranes on the market that can assemble large-capacity units at the dock. Even if crane resources exist, the carrying capacity of the dock is very limited. There are very few docks in China that can meet such a large carrying capacity. Therefore, in order to reduce the construction cost of floating units, the best way is to install floating units at offshore machine sites.

[0044] The offshore installation of floating units generally uses a self-elevating platform to lift the units onto the floating foundation. The unit components are a static-to-dynamic docking, which is slightly difficult. As the water depth in deep sea areas becomes deeper and deeper, when the water depth exceeds 80m, there are currently no applicable installation ships in China, and only large floating cranes can be used to install the units. The installation of unit components by floating cranes is a dynamic-to-dynamic docking, which is more difficult than with self-elevating platforms.

[0045] Therefore, in the face of large-capacity units in the era of power parity, under the conditions of such scarce crane resources, dock resources and self-elevating platform resources, how to complete the installation and operation and maintenance of large-capacity floating units in deep sea areas and reduce the installation and operation and maintenance costs is a question worthy of deep thought.

[0046] At present, the floating units installed in the domestic market, when the wind turbines used are small megawatt models between 5MW and 8MW, the weight and hub center height of the wind turbines are relatively small. The wind turbines are hoisted onto the floating foundation by cranes at the dock. The cranes are also relatively small, and the bearing capacity requirements for the dock are relatively low. However, in the future, floating units will gradually develop towards the deep sea, and the capacity of units installed on floating foundations will also gradually increase, basically all of which are wind turbines above 10MW. Faced with these heavy and high-capacity wind turbines, it is difficult to find large-sized and large-tonnage cranes on the market to meet the needs of unit hoisting at the dock. At the same time, the carrying capacity of domestic docks is limited. If large-sized crawler cranes are needed, the docks need to be reinforced, and the cost of dock reconstruction will increase. Moreover, for small-scale floating wind turbine projects, long-term occupation of the dock and high dock rental fees will bring great construction costs to the project. Furthermore, when encountering deep-sea projects, after the floating wind turbines are installed at the dock, the floating foundation and wind turbines need to be towed over long distances from the dock to the offshore machine site. If strong convective weather or typhoons are encountered during the towing process, the transportation risk is very high and the consequences will be disastrous.

[0047] Therefore, the installation of floating units will be slowly moved to the sea, but there will be problems with the installation of floating units at sea. As the water depth of the project increases, the jack-up platform is limited by the performance parameters of the pile legs, and the available jack-up platform resources are becoming less and less. It is necessary to consider the installation plan of floating units hoisted at sea by floating cranes. At the same time, the existing floating wind turbine foundation has a large component replacement plan of towing the entire buoy and wind turbine to the dock for large component replacement, which makes the maintenance cost of the floating unit very high.

[0048] It can be seen that based on the future floating unit projects in deep sea areas, it is necessary to develop an assembly tool that can be used for the offshore installation and operation and maintenance of floating units by floating cranes in deep sea areas. This can ensure that the process of installing large-capacity units on floating foundations and replacing large components of units at offshore machine sites by floating cranes can be realized, thereby reducing dependence on dock cranes, dock resources, and self-elevating platforms, thereby reducing construction and operation and maintenance costs, and eliminating the floating foundation and the overall towing link of the wind turbine to reduce transportation risks. This is an urgent need of the floating wind power market after the parity era.

[0049] like Figures 1 to 5 As shown, based on this, an embodiment of the present application provides an assembly tool for assembling a hub 1 and a blade 2, the assembly tool includes a main support member 10 and an auxiliary docking member 20, the main support member 10 has a predetermined height along the first direction X, one end of the main support member 10 in the first direction X is configured to support the hub 1 and the other end is configured to be connected to the carrier. The auxiliary docking member 20 includes an adjustment component 22 and a clamping component 21, the clamping component 21 has a clamping cavity 21a that passes through along the second direction Y to accommodate and fix the blade 2, the adjustment component 22 is connected to the clamping component 21 and can adjust the relative position of the clamping component 21 and the main support member 10 in at least two directions, so that the blade 2 is centered with the hub 1, and the second direction Y intersects with the first direction X.

[0050] The main support member 10 may be a cylindrical, columnar or hollow truss structure, etc., and has a certain strength to support the hub 1 or the engine room 3, the nose of the hub 1, etc. One end of the main support member 10 may be detachably connected to the engine room 3 by fastener connection. The other end of the main support member 10 may be connected to a support structure such as a carrier by welding or bolt fastening.

[0051] The auxiliary docking member 20 can be connected to the main support member 10 and supported by the main support member 10. Of course, the auxiliary docking member 20 can be arranged on a carrier and supported by a supporting structure on the carrier to ensure the use requirements of the auxiliary docking member 20 with the main support member 10.

[0052] The clamping assembly 21 can be used to clamp and fix the blade 2. It can adopt an openable and closable clamping structure so that the blade 2 can be taken and placed. Of course, the blade 2 can also be inserted into the clamping assembly 21 through one end of its own length direction to ensure the clamping and fixing requirements of the blade 2.

[0053] The adjusting component 22 can move freely in two directions, three directions, etc. The adjusting component 22 drives the clamping component 21 to move, thereby driving the blade 2 to move in at least two directions to ensure docking with the hub 1.

[0054] The first direction X and the second direction Y may intersect, and of course, may be selected to be perpendicular to each other.

[0055] An assembly tool provided by an embodiment of the present application includes a main support member 10 and an auxiliary docking member 20. The main support member 10 is used to support the hub 1 at a predetermined height along the first direction X. The hub 1 can be first connected to the nacelle 3 and then supported on the main support member 10. The auxiliary docking member 20 includes an adjustment component 22 and a clamping component 21. The clamping cavity 21a provided through the clamping component 21 along the second direction Y can be used to accommodate and fix the blade 2. Since the adjustment component 22 can adjust the position of the clamping component 21 relative to the main support member 10 in at least two directions, the relative position of the blade 2 and the hub 1 can be adjusted, thereby reducing the difficulty of splicing the blade 2 and the hub 1, which is beneficial to the construction of the wind turbine generator set. In particular, for the construction of offshore wind turbines, the carrier can be a floating crane, and the assembly tool can be fixed on the floating crane to transport the blade 2, the hub 1, the nacelle 3 and other components to the offshore position of the wind turbine generator set for assembly, and the adjustment of the auxiliary docking member 20 is used. Compared with pure crane suspension splicing, it can not only ensure the stability of the blade 2 in the air, but also make the position adjustment of the blade 2 simpler and more accurate, thereby reducing the difficulty of splicing the blade 2 and the hub 1.

[0056] like Figures 1 to 3 As shown, in some optional embodiments, an assembly tool provided by an embodiment of the present application, the clamping assembly 21 includes a fixed support 211, a first driving member 212 and a pair of clamping units 213, the pair of clamping units 213 are relatively distributed on both sides of the fixed support 211 and are respectively rotatably connected to the fixed support 211, the fixed support 211 and the pair of clamping units 213 are enclosed to form a clamping cavity 21a, the first driving member 212 is connected between the clamping unit 213 and the fixed support 211 and can drive the clamping unit 213 to rotate relative to the fixed support 211 to clamp or release the blade 2.

[0069] Optionally, the fixed frame 2131 and the bottom frame 2112 arranged in pairs are spliced ​​together to form an annular structure as a whole.

[0070] In some optional embodiments, the second driving member 2133 includes a power source 2133a and an adjusting member. The adjusting member partially passes through the avoidance opening 2131a and is universally connected to the clamping block 2132. The power source 2133a drives the adjusting member to move and changes the depth of the adjusting member inserted into the avoidance opening 2131a and extending into the inner side of the fixed frame 2131.

[0097] An assembly tool provided in an embodiment of the present application enables the adjustment component 22 to further include a second adjustment unit 224, so that the adjustment component 22 can adjust the relative position of the clamping component 21 and the main support member 10 in at least three directions, which is beneficial to the splicing of the blade 2 and the hub 1 and effectively reduces the difficulty of splicing.

When assembling the blades 2 and the hub 1 at sea, it can reduce the difficulty of the floating crane to bear the weight of the assembly tool.

[0105] Continue reading Figures 1 to 4 As shown, in some optional embodiments, an assembly tool provided by an embodiment of the present application, the main support member 10 includes a column 11 and a rotating component 12, the rotating component 12 includes a bearing 121 and a rotating drive member 122, the bearing 121 includes a rotating ring 1211 and a fixed ring 1212 for rotational cooperation, the fixed ring 1212 is connected to the column 11 and the rotating ring 1211 is used to connect to the cabin 3 connected to the hub 1, the rotating drive member 122 is connected to the rotating ring 1211 and drives the rotating ring 1211 to rotate relative to the fixed ring 1212.

[0106] An assembly tool provided in an embodiment of the present application, in which the main support member 10 adopts the above-mentioned structural form, can not only ensure the supporting effect of the nacelle 3 connected to the hub 1, but also can perform planar rotation of the nacelle 3 and the hub 1 as required, and change the angular relationship between the nacelle 3 and the auxiliary docking member 20, thereby further ensuring the requirement for rapid splicing of the blade 2 and the hub 1.

[0107] In some optional embodiments, the assembly tool provided by one embodiment of the present application, the rotating drive member 122 may include a fourth motor 1221 and a driving wheel 1222. The fourth motor 1221 is connected to the column 11 and may be connected to the column 11 through a connecting plate. The output section of the fourth motor 1221 is connected to the driving wheel 1222, and the driving wheel 1222 is meshed with the rotating circle 1211. The rotating circle 1211 may be the inner ring of the bearing 121, and of course, may also be the outer ring of the bearing 121, and may be the inner ring of the bearing 121.

[0108] In an assembly tool provided by an embodiment of the present application, the rotating driving member 122 adopts the above-mentioned form, which can ensure the driving effect of the rotating circle 1211 of the bearing 121, and further ensure the rotation requirement of the head formed by the cabin 3 and the hub 1 with the column 11 as the center.

[0109] In some optional embodiments, an assembly tool provided by an embodiment of the present application has a plurality of rotating drive members 122 , and the plurality of rotating drive members 122 are spaced apart in the circumferential direction of the column 11 , and the driving wheel 1222 of each rotating drive member 122 is respectively meshed with the rotating circle 1211 .

[0110] In some optional embodiments, an assembly tool provided by one embodiment of the present application has a cavity in the column 11 , each rotating driving component 122 is located in the inner cavity, and the rotating circle 1211 can be selected as the inner circle of the bearing 121 .

[0111] In some optional embodiments, an assembly tool provided in an embodiment of the present application, by disposing the rotating drive component 122 in the inner cavity of the column 11, is beneficial to the protection of the rotating drive component 122 and can avoid the risk of interference when the blade 2 is assembled with the hub 1.

[0112] In some optional embodiments, in the assembly tooling provided by the above-mentioned embodiments of the present application, a centering sensor 40 is provided on the clamping assembly 21 , and the centering sensor 40 is configured to feed back the centering information of the blade 2 and the hub 1 .

[0113] Optionally, during assembly, a corresponding sensor 1a can be set on the hub 1. The sensor 1a can be specifically set on the web 1b corresponding to the hub 1 and each pitch bearing. The centering sensor 40 can sense the sensor 1a. The centering sensing information between the centering sensor 40 and the sensor 1a can determine the stop position of the adjustment component 22 to adjust the clamping component 21 relative to the main support member 10.

[0114] Exemplarily, the centering sensor 40 may be disposed in the central area of ​​the top of the clamping assembly 21, and may be optionally connected to a circular ring-shaped structure formed by splicing a fixed frame 2131 and a bottom frame 2112 arranged in pairs.

[0115] The sensor 1a can be set at the center of the web 1b of the hub 1. When the two are aligned and sensed, it can be determined that the clamping assembly 21 is facing the web 1b of the hub 1. Then, the center of the blade 2 can be made to face the center of the web 1b of the hub 1 by extending the lifting unit 222. The above arrangement facilitates the position adjustment of the clamping assembly 21 and reduces the difficulty of docking between the blade 2 and the hub 1.

[0116] Continue reading Figures 1 to 5As shown, in some optional embodiments, an assembly tool provided by an embodiment of the present application has a first acceleration sensor 50 disposed on the adjustment component 22, and the first acceleration sensor 50 is configured to feedback the heave acceleration of the auxiliary docking member 20, and a second acceleration sensor 60 is disposed on the main support member 10, and the second acceleration sensor 60 is configured to feedback the heave acceleration of the main support member 10.

[0117] The heave acceleration may be understood as the acceleration along the first direction X.

[0118] When the assembly tool is used at sea and moved to the deep sea area with the floating crane, when the hub 1 and the blade 2 are directly assembled in the deep sea area, the floating crane will have certain shaking and other movements due to the action of seawater. By setting the first acceleration sensor 50 and the second acceleration sensor 60, the heave acceleration of the auxiliary docking member 20 and the heave acceleration of the auxiliary docking member 20 can be obtained, and then the heave acceleration of the hub 1 and the heave acceleration of the blade 2 can be fed back. The heave acceleration of the auxiliary docking member 20 fed back by the first acceleration sensor 50 can finally obtain the heave amplitude of the blade 2, and the heave acceleration of the main support member 10 fed back by the second acceleration sensor 60 can finally obtain the heave amplitude of the hub 1. When there is a difference between the heave amplitude of the blade 2 and the heave amplitude of the hub 1, the length of the lifting unit 222 can be adjusted to compensate for the interpolation, so that the web of the blade 2 and the hub 1 can be guaranteed to be aligned even in a floating or shaking state, reducing the difficulty of splicing the hub 1 and the tower in the deep sea area.

[0119] It is most difficult to dock the blade 2 with the hub 1 on a shaking floating crane, because the bolts connecting the blade 2 with the pitch bearing 121 of the hub 1 are horizontal. Once the head and the blade 2 are misaligned up and down due to the shaking of the floating crane, it is difficult to insert the bolts of the blade 2 into the pitch bearing. Even if the blade root bolts are inserted, they will be damaged by shear force. The assembly tool is installed on the floating crane for the assembly of the unit. First, the head composed of the hub 1 and the blade 2 is hoisted to the top of the column 11. When the rotating assembly 12 is included, the cabin 3 can be docked with the rotating circle 1211, and the rotating circle 1211 is driven to rotate relative to the fixed circle 1212 by the rotating drive 122, thereby realizing the rotation of the head, which can make the length direction of the head parallel to the width direction of the base plate 221.

[0120] For different aircraft nose lengths, the second mobile platform 2241 of the second adjustment unit 224 of the auxiliary docking member 20 has a moving function in the third direction Z, or a lateral moving function. The blade 2 can be moved to the front of the variable pitch bearing 121 of the hub 1 through the second adjustment unit 224, and the transmission wheel 2243b is rotated through the action of the fifth driving member 2243, so that the traction member 2243c rotates periodically, and the traction member 2243c can carry the second mobile platform 2241 to move laterally on the second guide member 2242. The first mobile platform 2231 of the first adjustment unit 223 of the auxiliary docking member 20 has a moving function in the second direction Y, or a longitudinal moving function. The blade 2 is placed on the fixed support 211 of the clamping assembly 21 and the clamping units 213 arranged in pairs have clamped the blade 2 to ensure that the blade 2 does not swing left and right. When the blade 2 is further inserted into the variable pitch bearing of the hub 1, there is no need to use the crane of the floating crane to move the blade 2 longitudinally. The blade 2 can be inserted into the variable pitch bearing 121 by the movement function of the first adjustment unit 223 in the second direction Y. The fourth driving member 2233 is actuated to drive the screw 2233b to rotate so that the first moving platform 2231 moves on the second guide rail. The lifting unit 222 of the auxiliary docking member 20 has a heave compensation function in the first direction X. On the one hand, through the action of the third driving member 2222, the first arm 2221a and the second arm 2221b rotate relative to each other to realize the up and down movement of the lifting unit 222, which can lift the blade 2 so that the root center of the blade 2 is aligned with the center of the variable pitch bearing 121 of the hub 1.

[0121] On the other hand, through its automatic compensation function, the root center of the blade 2 is always aligned with the center of the pitch bearing of the hub 1. The adjustment component 22 is provided with a first acceleration sensor 50, which is configured to feedback the heave acceleration of the auxiliary docking member 20. The main support member 10 is provided with a second acceleration sensor 60, which is configured to feedback the heave acceleration of the main support member 10. The heave amplitude of the blade 2 can be finally obtained by the heave acceleration of the auxiliary docking member 20 fed back by the first acceleration sensor 50, and the heave amplitude of the hub 1 can be finally obtained by the heave acceleration of the main support member 10 fed back by the second acceleration sensor 60. When there is a difference between the heave amplitude of the blade 2 and the heave amplitude of the hub 1, the interpolation can be compensated by adjusting the length of the lifting unit 222, so that the web of the impeller and the hub 1 can be ensured to be aligned even in a floating or shaking state, reducing the difficulty of splicing the hub 1 and the tower in the deep sea area.

[0122] In addition, the clamping assembly 21 has a stabilizing function, and can make the left and right clamping blocks 2132 clamp the blade 2 according to the root diameter of different blades 2 to ensure that the blade 2 does not swing left and right. Through the action of the power source 2133a, the screw 2133b rotates, and the C-shaped arm 2133c can carry the left and right clamping blocks 2132 to achieve the fixing and releasing action of the blade 2. During clamping, the clamping force is detected by the pressure sensor 2134 on the surface of the clamping block 2132. The clamping condition is completed when the clamping force reaches the design requirements. The clamping assembly 21 of the auxiliary docking member 20 also has an opening and closing function. Through the action of the first driving member 212, the left and right clamping units 213 arranged in pairs of the fixed support 211 can be rotated to achieve the opening and closing action.

[0123] The assembly tool provided in the embodiment of the present application has the following advantages:

[0124] 1. With this assembly tool, in the face of future deep sea areas, even if there is no jack-up platform available on the market, a floating crane can be used at the offshore machine site to lift the large-capacity unit onto the floating foundation, ensuring the feasibility of the future deep-sea large-capacity floating unit at sea construction technology.

[0125] 2. By adopting the assembly tool, the blade 2 and the head can be docked and installed in a moving state on the floating crane. Through the lifting unit 222, the first acceleration sensor 50, and the second acceleration sensor 60 of the assembly tool, the blade 2 and the hub 1 can be in a relatively static state, the docking efficiency of the blade 2 is higher, and the bolt tightening of the blade 2 is safer.

[0126] 3. By adopting this assembly tooling, floating wind turbines can be installed at sea using a floating crane. There is no need for a self-elevating platform, no need to select a large-sized and large-tonnage dock crane at the dock, and no need to occupy dock resources to transform the dock's bearing capacity. This can greatly reduce the construction cost of large-capacity floating units. At the same time, when installing floating units at sea, there is no need to tow the floating foundation and wind turbine as a whole, which greatly reduces the towing cost and the uncertain risks during the towing process (such as typhoon interference).

[0127] 4. The use of this assembly tooling can also take into account the replacement of large components of the floating unit in the later stage, ensuring the feasibility of future deep-sea large-capacity floating units at sea. There is no need to use the existing method of towing the entire floating body and wind turbine to the dock for replacement of large components, which greatly reduces the maintenance cost of the floating unit.

[0128] 5. The assembly tool can be used for the assembly of different blades 2 of different models. The lateral moving platform of the tool can make different blades 2 face the variable pitch bearings of different hubs 1. The spacing between the left and right clamping blocks 2132 of the supporting and fixing mechanism of the tool can be adjusted to stabilize different blades 2 and reduce swing amplitude.

[0129] 6. The assembly tooling can also be used for offshore installation of floating cranes and operation and maintenance of fixed units.

[0130] 7. When the floating crane hoists the blade 2 into the clamping assembly 21 of the auxiliary docking tooling, if the blade 2 is difficult to insert into the circular frame due to shaking, the clamping units 213 arranged in pairs in the clamping assembly 21 can be opened, and after the blade 2 is hoisted onto the fixed support 211, the clamping assembly 21 arranged in pairs can be closed to proceed to the next step to ensure the installation requirements of the blade 2.

[0131] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
