Abstract
Description
Technical Field
[0001] This utility model belongs to the field of anchor plate technology, and in particular relates to an anchor plate structure for a wind turbine tower base. Background Art
[0002] Anchor plates are used to fix the base of wind turbine towers to prevent the generator from shaking and being damaged by excessive wind. There are two types of anchor plates: flat plate and channel plate. Flat plate anchor plates are the most widely used. The anchor plate of the flat plate anchor plate is buried in the ground by anchor bars welded to it, and the frame is welded to the exposed anchor plate. Channel anchor plates are made by burying C-shaped steel channels and their anchors in the ground, and the frame is fixed in the channel of the anchor plate by bolts.
[0003] The existing technology has the following problems: When fixing the anchor plate of the existing wind turbine tower base, it is fixed by the friction between the long screw and the foundation. When drilling holes for installation, the anchor plate is prone to displacement, resulting in deviation between the drilled holes and the installation holes of the anchor plate, which is not convenient for fixing the anchor plate. It is also inconvenient to pour cement for fixing the anchor plate, making cement pouring extremely difficult. In order to facilitate the installation of the anchor plate, an anchor plate structure for the wind turbine tower base is proposed. When installing the anchor plate, the surrounding support components can stably fix the anchor plate, preventing displacement during installation and facilitating secondary fixing of the anchor plate by pouring cement. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides an anchor plate structure for a wind turbine tower base. This structure offers the advantage of auxiliary fixing during anchor plate installation, solving the problems of existing wind turbine tower base anchor plates which rely on friction between long screws and the foundation for fixation. During drilling for anchor plate installation, the anchor plate is prone to shifting, causing deviations between the drilled holes and the anchor plate's mounting holes, making anchor plate fixing difficult and inconvenient during concrete pouring. To facilitate anchor plate installation, this invention proposes an anchor plate structure for a wind turbine tower base. During installation, the surrounding support components provide stable fixation of the anchor plate, preventing shifting during installation and facilitating secondary fixing during concrete pouring.
[0005] This utility model is implemented as follows: an anchor plate structure for a wind turbine tower base includes an anchor plate, fixing pins, a connecting seat, and a support mechanism. Fixing pins are provided around the perimeter of the anchor plate, with the bottom of each pin extending to the bottom of the anchor plate. A fixing cap is threaded onto the top of each fixing pin. The top of the anchor plate is fixedly connected to the bottom of the connecting seat by bolts. Four support mechanisms are provided at the bottom of the anchor plate. A fixing cavity is formed at the bottom of the anchor plate, and a positioning mechanism is provided inside the fixing cavity. The positioning mechanism works in conjunction with the support mechanism.
[0006] As a preferred embodiment of this utility model, the bottom of the anchor plate is provided with a limiting groove, and the inner wall of the limiting groove is provided with a moving groove. The moving groove is used in conjunction with the support mechanism. By setting the limiting groove, the sliding block can be adjusted more smoothly, making it easier for the operator to operate.

The surface of the sliding block is movably connected to the interior of the anchor plate, and the bottom of the sliding block is movably connected to the top pivot of the support rod. The bottom of the support rod extends through the interior of the ground. By setting up the support mechanism, the anchor plate can be assisted in fixing during installation to prevent the anchor plate from shaking during installation.
[0008] In a preferred embodiment of this invention, the positioning mechanism includes a moving rod, a positioning rod, and a tension spring. The bottom of the moving rod extends through to the bottom of the anchor plate, and the top of the moving rod extends through to the interior of the anchor plate. The left side of the anchor plate is fixedly connected to the right side of the tension spring, and the left side of the tension spring is fixedly connected to the inner wall of the fixing cavity. The tension spring is sleeved on the surface of the positioning rod, and the right side of the positioning rod is fixedly connected to the left side of the moving rod. The left side of the positioning rod extends through to the interior of the support rod. By setting up the positioning mechanism, the support rod can be retracted when the anchor plate is moved, saving space and facilitating placement.
[0009] As a preferred embodiment of this utility model, the fixed cavity is provided with a stroke groove, which is used in conjunction with the moving rod. By providing the stroke groove, the moving rod can move according to the movement trajectory provided by the stroke groove, preventing it from exceeding the stroke during use and causing structural damage.
[0010] As a preferred embodiment of this utility model, the surface of the support rod is provided with a fixing groove. The fixing groove is used in conjunction with the positioning rod. By setting the fixing groove, the positioning rod can be accurately inserted into the fixing groove during the insertion and fixing process, so as to make it stable and prevent loosening.
[0011] As a preferred embodiment of this utility model, the top of the fixing pin is provided with a pouring port, and the surface of the fixing pin is provided with a pouring groove that cooperates with the pouring port. By setting the pouring port and the pouring groove, the fixing pin can be stably fixed when it is poured and fixed, ensuring uniform pouring of cement.
[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0013] 1. This utility model, through the coordinated use of anchor plates, fixing pins, connecting seats, support mechanisms, and positioning mechanisms, facilitates the operation of workers when handling or placing the anchor plates, preventing injury to surrounding personnel. It addresses the shortcomings of existing wind turbine tower base anchor plates, which rely on the friction between long screws and the foundation for fixation. In these existing systems, the anchor plates are prone to shifting during drilling, leading to misalignment between the drilled holes and the anchor plate's mounting holes, hindering fixation and making cement pouring extremely inconvenient. To address this, a new anchor plate structure for wind turbine tower bases is proposed. During installation, the surrounding support components provide stable fixation of the anchor plate, preventing shifting during installation and facilitating secondary fixation during cement pouring.
[0014] 2. By setting a fixing pin, this utility model can allow cement to enter from the pouring port and flow out through the pouring groove until it is filled, thereby increasing the secondary fixing effect of the fixing pin. Attached Figure Description

The bottom of the anchor plate 1 is provided with four support mechanisms 4. The bottom of the anchor plate 1 is provided with a fixing cavity 6. The fixing cavity 6 is provided with a positioning mechanism 7. The positioning mechanism 7 works in conjunction with the support mechanism 4.
[0024] refer to Figure 2 An anchor plate 1 has a limiting groove 8 at its bottom and a moving groove 9 on its inner wall. The moving groove 9 is used in conjunction with the support mechanism 4.
[0025] By adopting the above solution, by setting the limiting groove 8, the adjustment of the position of the sliding block 401 can be made smoother, making it easier for the staff to operate.
[0026] refer to Figure 2 and Figure 4 The support mechanism 4 includes a sliding block 401 and a support rod 402. The surface of the sliding block 401 is movably connected to the interior of the anchor plate 1, the bottom of the sliding block 401 is movably connected to the top of the support rod 402, and the bottom of the support rod 402 extends through the interior of the ground.
[0027] The above solution is adopted: by setting up a support mechanism 4, the anchor plate 1 can be fixed in place during installation to prevent it from shaking.
[0028] refer to Figure 3The positioning mechanism 7 includes a moving rod 701, a positioning rod 702, and a tension spring 703. The bottom of the moving rod 701 extends through to the bottom of the anchor plate 1, and the top of the moving rod 701 extends through to the interior of the anchor plate 1. The left side of the anchor plate 1 is fixedly connected to the right side of the tension spring 703, and the left side of the tension spring 703 is fixedly connected to the inner wall of the fixing cavity 6. The tension spring 703 is sleeved on the surface of the positioning rod 702, and the right side of the positioning rod 702 is fixedly connected to the left side of the moving rod 701. The left side of the positioning rod 702 extends through to the interior of the support rod 402.
[0029] By adopting the above solution, the positioning mechanism 7 can be set up so that the support rod 402 can be retracted when the anchor plate 1 is moved, which saves space and facilitates placement.
[0030] refer to Figure 3 The fixed cavity 6 has a stroke groove 11 inside, which is used in conjunction with the moving rod 701.
[0031] By adopting the above solution, by setting the stroke groove 11, the moving rod 701 can move according to the movement trajectory provided by the stroke groove 11, preventing it from exceeding the stroke during use and causing structural damage.
[0032] refer to Figure 3 The surface of the support rod 402 is provided with a fixing groove 12, which is used in conjunction with the positioning rod 702.
[0033] By adopting the above solution, by setting the fixing groove 12, the positioning rod 702 can be accurately inserted into the fixing groove 12 during the plug-in fixing, so that it is stably fixed and prevents loosening.
[0034] refer to Figure 1 The top of the fixing pin 2 is provided with a pouring port 13, and the surface of the fixing pin 2 is provided with a pouring groove 14 that is used in conjunction with the pouring port 13.
[0035] By adopting the above scheme, by setting the pouring port 13 and the pouring groove 14, the fixing pin 2 can be stably fixed when it is poured and fixed, thus ensuring the uniform pouring of cement.
[0036] The working principle of this utility model:
[0037] When installing the anchor plate 1, pull the moving rod 701 inward. The moving rod 701 moves the positioning rod 702 inward according to the movement trajectory provided by the stroke groove 11. While the positioning rod 702 moves inward, it stretches the tension spring 703, making the positioning rod 702 move away from the inside of the fixing groove 12. At this time, the sliding block 401 can be pulled outward. The sliding block 401 moves outward according to the movement trajectory provided by the moving groove 9. After completion, the support rod 402 is rotated through the pivot to make it perpendicular to the ground. After the fixing pin 2 is installed on the ground, cement is poured in through the top pouring port 13. The cement is used to fix the fixing pin 2 a second time through the pouring groove 14 to prevent loosening.
[0038] In summary, the anchor plate structure of this wind turbine tower base, through the coordinated use of anchor plate 1, fixing pin 2, connecting seat 3, support mechanism 4, sliding block 401, support rod 402, fixing cover 5, fixing cavity 6, positioning mechanism 7, moving rod 701, positioning rod 702, tension spring 703, limiting groove 8, moving groove 9, stroke groove 11, fixing groove 12, pouring port 13, and pouring groove 14, solves the problem of existing wind turbine tower base anchor plates relying on the friction between the long screw and the foundation for fixation. When drilling holes for anchor plate installation, the anchor plate is prone to shifting, causing deviations between the drilled holes and the anchor plate's mounting holes. This makes it difficult to fix the anchor plate and inconvenient to pour cement for fixing. To facilitate anchor plate installation, an anchor plate structure for wind turbine tower base is proposed. During installation, the anchor plate is stably fixed by the surrounding support components, preventing shifting during installation and facilitating secondary fixing during anchor plate pouring.
