[0001] This utility model relates to the field of wind turbine generators, and in particular to a wind turbine generator anchor plate for foundation bolts. Background Technology
[0002] Anchor plates for wind turbine foundation bolts are one of the key components in the installation process of wind turbine towers. They are used to firmly connect the wind turbine tower to the foundation to ensure that the wind turbine can stably withstand the enormous pressure from the wind and the impact of other environmental factors during operation.
[0003] When using anchor plates for wind turbine foundation bolts, the bolts and anchor plate bodies are connected via through holes. Nuts are then threaded onto the bolts, and the anchor plate body is installed on the ground. When the anchor plate body contacts the ground, unevenness can cause gaps and suspension between the anchor plate body and the ground. Under stress, the anchor plate body is prone to tilting, leading to localized stress concentration and increased fatigue damage to the bolts. This ultimately affects the performance of the anchor plate for foundation bolts. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that when the anchor plate body is in contact with the ground, due to the deviation of the ground flatness, there is a partial gap between the anchor plate body and the ground, which causes the anchor plate body to be suspended. Then, when the anchor plate body is subjected to force, it is easy to tilt, which causes local stress concentration and aggravates the fatigue damage of the fixing bolt, thus causing problems that affect the use effect of the anchor plate of the anchor bolt.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a wind turbine anchor plate, including an anchor plate body, a plurality of fixing bolts on one side of the anchor plate body, a nut on one side of the fixing bolts, a plurality of filling devices on one side of the anchor plate body, and the filling devices filling the gap between the anchor plate body and the ground through a first filling block and a second filling block.
[0006] Preferably, the filling device includes a square tube, a first bolt, a first filling block, and an adjustment component. The square tube is disposed on one side of the anchor plate body, the first bolt is threaded into one side of the square tube to be threadedly fixed to the first filling block, and the adjustment component is disposed on one side of the first filling block to adjust the size of the first filling block.
[0007] Preferably, the adjustment assembly includes a second bolt, a second filler block, and a placement groove formed on one side of the first filler block. The second bolt is inserted into one side of the second filler block and threadedly fixed to the first filler block. The size of the placement groove formed on one side of the first filler block is adapted to the size of the second filler block.
[0008] Preferably, a baffle is provided on one side of the first filling block to restrict the position of the second filling block in the slot inside the first filling block.
[0009] Preferably, a storage groove is provided on one side of the second filler block to store the nut of the second bolt.
[0010] Preferably, the second filler block has several anti-slip blocks on both sides to increase the friction on both sides of the second filler block.
[0011] Preferably, the first filling block has a trapezoidal block on the side near the square tube to reduce the size of one side of the first filling block.
[0012] Preferably, the placement groove on one side of the first filling block is T-shaped, and the size of the second filling block is adapted to the placement groove.
[0013] In summary, the beneficial effects of this utility model are as follows: By using a filling device, the gap between the anchor plate body and the ground can be filled and supported, avoiding the situation where the anchor plate body is suspended due to ground flatness deviation, and the anchor plate body is prone to tilting under force, which will aggravate the fatigue damage of the fixing bolt due to local stress concentration, thereby improving the service effect of the anchor plate.
[0014] By using the adjustment components, the overall size of the first and second filler blocks can be adjusted to adapt the filling device to gaps of different thicknesses between the anchor plate and the ground, thereby improving the adaptability of the filling device.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] Figures 1 to 6 The wind turbine anchor plate shown includes an anchor plate body 1. A plurality of fixing bolts 2 are provided on one side of the anchor plate body 1, and nuts 3 are provided on one side of the fixing bolts 2. A plurality of filling devices 4 are provided on one side of the anchor plate body 1. The filling devices 4 fill the gap between the anchor plate body 1 and the ground through a first filling block 43 and a second filling block 442. When the anchor plate is used for wind turbine anchor bolts 2, the fixing bolts 2 are connected to the through holes of the anchor plate body 1, and then the nuts 3 are threaded onto the fixing bolts 2. The anchor plate body 1 is then installed on the ground, and the filling devices 4 are used to fill the gap between the anchor plate body 1 and the ground.
[0021] Figures 1 to 6 The filling device 4 shown includes a square tube 41, a first bolt 42, a first filling block 43, and an adjustment component 44. The square tube 41 is provided on one side of the anchor plate body 1. The first bolt 42 is threaded into one side of the square tube 41 to be threadedly fixed with the first filling block 43. The adjustment component 44 is provided on one side of the first filling block 43 to adjust the size of the first filling block 43.
[0022] Figures 1 to 6When there is a gap between the anchor plate body 1 and the ground, the square tube 41 can be welded and fixed to one side of the anchor plate body 1. Then, the size of the first filling block 43 can be adjusted using the adjustment component 44 to make the size of the first filling block 43 fit the size of the anchor plate body 1. Then, the first filling block 43 is moved so that one side of the first filling block 43 is inserted into the square tube 41, and the first filling block 43 fills and supports the gap between the ground and the anchor plate body 1. Then, the first bolt 42 is rotated so that the first bolt 42 passes through the square tube 41 and is fixed to the first filling block 43, thus using the filling device 4. By using the filling device 4, the gap between the anchor plate body 1 and the ground can be filled and supported, avoiding the situation where there is a partial gap between the anchor plate body 1 and the ground due to the unevenness of the ground. Then, the anchor plate body 1 is prone to tilting after being stressed, which will cause local stress concentration and aggravate the fatigue damage of the fixing bolt 2, thereby improving the performance of the anchor bolt anchor plate.
[0023] Figures 1 to 6 The adjustment assembly 44 shown includes a second bolt 441, a second filler block 442, and a placement groove 443 formed on one side of the first filler block 43. The second bolt 441 is inserted into one side of the second filler block 442 and threadedly fixed to the first filler block 43. The size of the placement groove 443 on one side of the first filler block 43 is adapted to the size of the second filler block 442. Before using the first filler block 43, the second filler block 442 with the adapted size is inserted into the placement groove 443 on one side of the first filler block 43. Then, the second bolt 441 is rotated so that the second bolt 441 is inserted into one side of the second filler block 442 to be threadedly fixed to the first filler block 43, thereby fixing the positions of the first filler block 43 and the second filler block 442. Then, the size of the first filler block 43 is adjusted. By using the adjustment assembly 44, the overall size of the first filler block 43 and the second filler block 442 can be adjusted so that the filling device 4 can adapt to gaps of different thicknesses between the anchor plate and the ground, thereby improving the adaptability of the filling device 4.
[0024] Figures 1 to 6 A baffle 445 is provided on one side of the first filling block 43 to restrict the position of the second filling block 442 in the placement groove 443 inside the first filling block 43. By fixing the baffle 445 to one side of the first filling block 43, the position of the second filling block 442 in the placement groove 443 inside the first filling block 43 is restricted, which facilitates the subsequent fixing of the second filling block 442.
[0025] Figures 1 to 6The second filler block 442 shown has a storage groove 446 on one side for storing the nut of the second bolt 441. The storage groove 446 on one side of the second filler block 442 allows for the storage and protection of the nut of the second bolt 441. Several anti-slip blocks 447 are provided on both sides of the second filler block 442 to increase the friction on both sides. These anti-slip blocks 447 are fixed to both sides of the second filler block 442, increasing the friction and making it easier for the operator to move the second filler block 442.
[0026] Figures 1 to 6 The first filler block 43 shown has a trapezoidal block 45 on the side near the square tube 41 to reduce the size of one side of the first filler block 43. By fixing the trapezoidal block 45 to one side of the first filler block 43, the size of that side is reduced, making it easier for the first filler block 43 to be inserted into the square tube 41. The placement groove 443 on one side of the first filler block 43 is T-shaped, and the second filler block 442 is adapted to the size of the placement groove 443. The T-shape of the placement groove 443 on one side of the first filler block 43 allows the second filler block 442 to better contact the first filler block 43, thereby improving the usability of the adjustment assembly 44.
[0027] Working principle: When the anchor bolt 2 of the wind turbine is used, the anchor bolt 2 and the anchor plate body 1 are connected through the hole. Then, the nut 3 is threaded to the anchor bolt 2. Then, the anchor plate body 1 is installed on the ground. At this time, the filling device 4 is used to fill the gap between the anchor plate body 1 and the ground. When there is a gap between the anchor plate body 1 and the ground, the square tube 41 can be welded and fixed to one side of the anchor plate body 1. Then, the size of the first filling block 43 can be adjusted using the adjustment component 44 to make the size of the first filling block 43 fit the size of the anchor plate body 1. Then, the first filling block 43 is moved so that one side of the first filling block 43 is inserted into the square tube 41, and the first filling block 43 fills and supports the gap between the ground and the anchor plate body 1. Then, the first bolt 42 is rotated so that the first bolt 42 passes through the square tube 41 and is fixed to the first filling block 43, thus enabling the use of the filling device 4. By using the filling device 4, the gap between the anchor plate body 1 and the ground can be filled and supported, avoiding the situation where there is a partial gap between the anchor plate body 1 and the ground due to the unevenness of the ground. This prevents the anchor plate body 1 from tilting under stress, causing local stress concentration and aggravating fatigue damage to the fixing bolt 2, thereby improving the performance of the anchor bolt anchor plate.
