[0002] The wind turbine fixing anchor assembly is an important component used to firmly install the base of the wind turbine to the ground. The assembly usually includes two annular anchor plates that are opposite each other, multiple circumferentially distributed anchor bolts between the two anchor plates, and bolts for fixing the anchor bolts and anchor plates.

[0003] At present, when assembling a component, one of the anchor plates is usually lifted by existing lifting equipment, and the other anchor plate is placed on the mounting base on the ground, and the two anchor plates are opposite to each other. Then, all the anchor bolts are manually inserted between the anchor plates in turn. After the insertion and placement of the anchor bolts are completed, the nuts on the corresponding anchor bolts are manually tightened in turn to lock and fix them. At this point, the assembly process of the component is completed. Secondly, it should be noted that this process requires multiple people to sit on the upper anchor plate and cooperate with the workers on the ground.

The opposite surfaces of the two locking plates on the same anchor plate are fixedly provided with L-shaped locking blocks corresponding to the anchor bolts one by one, and the sum of the thickness of the locking block and the thickness of the anchor plate is the same as the length of the clamping section.

[0013] According to a favorable embodiment, the opposite surfaces of the two corresponding locking plates on the same anchor plate are provided with avoidance grooves corresponding to the locking blocks one by one, and the avoidance grooves are used to avoid the required space for the locking plates to be inserted and installed on the anchor plate, and the anchor bolt is located between the corresponding avoidance grooves and the locking blocks.

[0014] According to a favorable embodiment, a docking groove is provided on one end portion of the anchor plate, the opening of which is chamfered, and a docking block is fixedly provided on the other end portion for cooperating with the docking groove on the adjacent anchor plate, and the assembly of the circular ring base is completed by snapping the docking block into the corresponding docking groove, and the preliminary assembly of the anchor bolt assembly is completed at the same time as the assembly of the two circular ring bases is completed.

DETAILED DESCRIPTION

[0033] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] like Figure 1 As shown, a wind turbine fixing anchor assembly comprises: two symmetrical plate groups, each of which comprises a plurality of circumferentially distributed anchor plates 1, see Figure 11 The anchor plates 1 are fan-shaped and the anchor plates 1 in the same plate group together form a circular base. A plurality of anchor bolts 2 with the axis of the anchor plate 1 as the center and the axis being vertical are arranged between the two opposite anchor plates 1.

[0035] like Figure 1 、 Figure 2 and Figure 11 As shown, a combination mechanism 3 for combining the anchor plates 1 and the anchor bolts 2 is commonly provided between all the anchor plates 1, and the combination mechanism 3 includes a bolt storage groove 30. The outer circumferential surface and the inner circumferential surface of the anchor plate 1 are both provided with a plurality of bolt storage grooves 30, and the inner and outer bolt storage grooves 30 correspond to each other one by one and the two corresponding inner and outer bolt storage grooves 30 are located on the diameter of the anchor plate 1.

[0036] like Figure 1 and Figure 10 As shown, two locking plates 31 distributed along the diameter direction of the anchor plates 1 are circumferentially slidably provided on the opposite back surfaces of the two relative anchor plates 1. The anchor bolts 2 stored in the bolt storage grooves 30 are locked by rotating the locking plates 31 to complete the locking installation between the two upper and lower relative anchor plates 1.

[0037] like Figure 4 、 Figure 5 and Figure 7 As shown, both ends of the anchor bolt 2 are provided with a clamping section 20 for clamping and installing with the bolt storage groove 30. The diameter of the clamping section 20 is smaller than the diameter of the remaining part of the anchor bolt 2. The diameter of the clamping section 20 is the same as the width of the bolt storage groove 30, and the vertical length of the clamping section 20 is greater than the thickness of the anchor plate 1.

[0038] like Figure 8 and Figure 9 As shown, nuts 32 are threadedly installed on the anchor bolts 2 at both ends of the fan-shaped structure on the anchor plate 1, and a locking frame 33 is provided. By tightening the nuts 32, the anchor plates 1 and anchor bolts 2 in the same plate group are locked, and the two adjacent anchor plates 1 are locked by the locking frame 33.

[0039] like Figure 3 and Figure 4 As shown, when the inner arc surfaces of the two anchor plates 1 in the same plate group face downward, the anchor bolts 2 corresponding to the outer circumferential surfaces of the anchor plates 1 are installed and placed, and the two opposite anchor plates 1 are initially connected. Thereafter, the outer arc surfaces of the anchor plates 1 face downward, and the anchor bolts 2 corresponding to the inner circumferential surfaces of the anchor plates 1 are installed and placed, completing the preliminary combination of the anchor plates 1 and the anchor bolts 2.

[0040] When working, assemble the two relative anchor plates 1 and all the anchor bolts 2 between them respectively. The assembly process is as follows: manually place the two anchor plates 1 in the same state and preliminarily adjust the distance between the two anchor plates 1 so that the distance is adapted to the length of the anchor bolts 2. When the inner arc surface of the anchor plate 1 faces upward, the worker manually places the anchor bolts 2 into the bolt storage grooves 30 on the inner arc surface of the anchor plate 1 in sequence, and rotates the installation locking plate 31. The locking plate 31 and the bolt storage groove 30 jointly fix the anchor bolts 2. Then, flip the anchor plate 1 and repeat the above process. Thus, the docking process between the upper and lower relative anchor plates 1 is completed. The assembly process between the anchor plates 1 is repeated multiple times to form multiple fan-shaped frames. Then, the multiple fan-shaped frames are formed into a preliminary assembly. The nuts 32 are manually rotated to completely lock the two relative anchor plates 1 and the adjacent anchor plates 1 at the same time. Thus, the formed assembly is locked and the assembly process is completed. Through the prefabricated assembly process, the anchor bolts 2 are assembled in advance, which ensures the strength of the assembly while simplifying the assembly process, avoiding the problem of cumbersome and inefficient overall assembly due to the anchor bolts 2 being too long and inconvenient to assemble manually.

[0041] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in order to enable the locking plate 31 to rotate circumferentially around the axis of the anchor plate 1, a plurality of arcuate grooves 10 with axes colinear with the axis of the anchor plate 1 are formed on the anchor plate 1. The locking plates 31 are slidably arranged in the corresponding arcuate grooves 10 through sliding columns arranged thereon. The opposite surfaces of the two locking plates 31 on the same anchor plate 1 are fixedly provided with L-shaped locking blocks 34 corresponding to the anchor bolts 2 one by one. The sum of the thickness of the locking block 34 and the thickness of the anchor plate 1 is the same as the length of the clamping section 20.

[0042] See Figure 3 and Figure 4There are two assembly states in the figure. When assembling two relative anchor plates 1 and the anchor bolt 2 therebetween, an existing external lifting machine is used to manually lift and move the anchor plate 1 so that the corresponding two anchor plates 1 are opposite to each other left and right, and the inner arc surfaces of the two anchor plates 1 face the same side. When the inner arc surfaces of the two anchor plates 1 face downward, the anchor bolt 2 to be assembled is manually placed into the bolt storage groove 30 corresponding to the outer arc surface of the anchor plate 1. It should be additionally explained here that the clamping section 20 of the anchor bolt 2 is placed into the corresponding bolt storage groove 30. Since the diameter of the anchor bolt 2 on both sides of the clamping section 20 is larger than the diameter of the bolt storage groove 30, the anchor bolt 2 and the anchor plate 1 are initially limited to each other at this time, which preliminarily limits the distance between the two anchor plates 1, which is convenient for the subsequent locking process of the locking plate 31.

[0043] After that, the locking plate 31 close to the outer arc surface of the anchor plate 1 is manually installed on the anchor plate 1 by means of a sliding post passing through the corresponding arc groove 10. At this time, the sliding post is located in the corresponding arc groove 10, so that the locking plate 31 can only slide circumferentially around the axis of the anchor plate 1. The locking plate 31 drives the locking block 34 thereon to move synchronously and makes the U-shaped area of ​​the locking block 34 gradually contact the clamping section 20. Finally, the locking block 34 and the anchor plate 1 are engaged with the anchor bolt 2 together, thereby completely clamping one end of the anchor bolt 2. The above process is repeated so that both ends of the anchor bolt 2 are limited and clamped. Then, the anchor plate 1 is turned over so that the outer arc surface of the anchor plate 1 faces downward and the above process is repeated to install the corresponding anchor bolt 2, and finally the preliminary assembly process between the two anchor plates 1 is completed.

[0044] In summary, the process of laying two anchor plates 1 flat and assembling the anchor bolts 2 on the ground in advance replaces the original method of requiring all anchor bolts 2 to be installed vertically one by one, simplifies the installation process of the anchor bolts 2, improves the convenience of the assembly process, eliminates the tedious manual vertical plug-in installation process, and improves the efficiency of the assembly operation.

[0045] like Figure 2 and Figure 3 As shown, in order to facilitate the sliding installation of the locking plate 31 onto the anchor plate 1, the opposite surfaces of the two corresponding locking plates 31 on the same anchor plate 1 are provided with avoidance grooves 11 corresponding to the locking blocks 34 one by one. The avoidance grooves 11 are used to avoid the required space for the locking plate 31 to be inserted and installed on the anchor plate 1, and the anchor bolt 2 is located between the corresponding avoidance grooves 11 and the locking blocks 34.

[0046] During the installation of the locking plate 31, the avoidance groove 11 is aligned with the corresponding anchor bolt 2, and then the sliding column is inserted and installed on the anchor plate 1. Through the avoidance of the avoidance groove 11, the locking plate 31 can be first installed to fit with the anchor plate 1, and then slide circumferentially to perform a preliminary locking action on the anchor bolt 2.

[0047] like Figure 2 、 Figure 9 and Figure 11As shown, one end of the anchor plate 1 is provided with a docking groove 12, the opening of the docking groove 12 is chamfered, and the other end is fixedly provided with a docking block 13 that cooperates with the docking groove 12 on the adjacent anchor plate 1. The assembly of the circular base is completed by snapping the docking block 13 into the corresponding docking groove 12. When the assembly of the two circular bases is completed, the preliminary assembly of the anchor bolt 2 assembly is preliminarily completed.

[0048] After completing the preliminary fixation of all the upper and lower relative anchor plates 1, the anchor plates 1 are assembled. The anchor plates 1 are hoisted to the position where the assembly needs to be installed through external hoisting equipment, and the position of the anchor plates 1 is adjusted through manual cooperation so that the docking blocks 13 on the anchor plates 1 are inserted into the corresponding docking grooves 12. Therefore, all the anchor plates 1 together form two circular bases. The preliminary assembly of the external frame of the assembly is completed. The cooperation between the docking grooves 12 and the docking blocks 13 guides the assembly process of the anchor plates 1, and all the anchor plates 1 in the same plate group are integrated into the required circular base to ensure the strength of the subsequently formed assembly.

[0049] like Figure 7 、 Figure 8 and Figure 9 As shown, threaded sections 21 are provided on the upper and lower sides of the anchor bolt 2, and the two threaded sections 21 on the same anchor bolt are located between the two clamping sections 20, and the nut 32 is threadedly sleeved on the threaded section 21 of the anchor bolt 2 close to the adjacent anchor plate 1. There are two locking frames 33 on the same anchor plate 1, and they are provided at one end of the fan-shaped structure on the anchor plate 1. One end of the locking frame 33 is movably sleeved on the corresponding anchor bolt 2 and is located between the nut 32 and the anchor plate 1, and a locking groove 330 is provided at the other end of the locking frame 33. By clamping the corresponding anchor bolt 2 on the anchor plate 1 into the locking groove 330 in the locking frame 33 on the adjacent anchor plate 1, the mutual fixation of the anchor bolts 2 on different anchor plates 1 is completed, and the opening of the locking groove 330 is chamfered.

[0050] When the nut 32 is tightened, the locking frame 33 is tightened to form a whole.

[0051] In summary, the assembly process of the assembly can be completed only by tightening the nuts 32 at both ends of each anchor plate 1, while ensuring the overall assembly strength, simplifying the operation steps, and improving the assembly efficiency. It should be noted that when the number of anchor bolts 2 on the same anchor plate 1 is large, the other anchor bolts 2 can be tightened by increasing the number of nuts 32 on the same anchor plate 1, thereby strengthening the connection strength between the two relative anchor bolts 2. The bolt connection method can also be replaced by existing processing connection methods such as welding.

[0052] like Figure 4 、 Figure 6 and Figure 10 As shown, a connecting groove 310 is provided on one side of the opposite surface of the two opposite locking plates 31, and a connecting block 311 is fixedly provided on the other side. The connecting block 311 is slidably inserted into the corresponding connecting groove 310 so that the anchor plate 1 is integrally locked. The opening of the connecting groove 310 is chamfered.

[0053] During the assembly of adjacent anchor plates 1, the connecting blocks 311 on the locking plates 31 slide and fit into the connecting grooves 310 on the adjacent locking plates 31, so that all the locking plates 31 together form a locking ring, so that the locking between the anchor bolt 2, the anchor plate 1 and the locking plate 31 forms an integrated lock. When local looseness occurs, the integrated locking can still maintain the locking effect of the anchor bolt 2 and the anchor plate 1, thereby increasing the overall locking strength, ensuring the strength of the subsequent assembly, and facilitating the subsequent assembly process of the overall assembly.

[0054] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0055] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "connected," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
