Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generator set equipment, in particular to an adjustable structure for fixing a tuning liquid three-column star-shaped damper of a wind power tower. Background Art

[0002] The tuned liquid three-column star damper (hereinafter referred to as the damper) inside the wind tower of an existing wind turbine generator system consists of a three-way prismatic water tank and three pipes connected to the three-way prismatic water tank at their bottom ends (each pipe consists of several sub-pipes, and adjacent sub-pipes are connected by flanges and bolts). The top of each pipe is connected to an upper platform (which is fixedly connected to the interior of the tower). The three-way prismatic water tank is supported by springs installed on a lower platform (which is fixedly connected to the interior of the tower). When the wind tower vibrates in multiple dimensions, the damper will also swing in multiple dimensions. Due to the limited internal structural space of the wind tower, there is a risk of the damper colliding with the inner wall of the tower. Furthermore, the wind tower with the damper installed needs to be flipped during the manufacturing process, which poses the risk of the damper being dislodged from its original installation position. Furthermore, when the wind tower is transported in a lying position, there is a risk of the damper shifting and colliding with the tower wall due to vibration and impact during transportation. Therefore, components are needed to fix and support the damper and eliminate possible collisions and impacts with the inner wall of the tower.

[0003] However, because the inner diameters of wind turbine towers vary, the fixing structure cannot be universally applied and must be designed based on the diameter. This increases the workload for designers and hinders design efficiency. Furthermore, because the damper has multiple sub-pipes that need to be fixed, each corresponding to a different inner diameter of the tower. During installation, the fixing components at each level must be separated according to the tower diameter, which increases the workload for installers and hinders installation efficiency. If the installation height of the three-way prismatic water tank in the center of the damper varies, the corresponding size of the fixing bracket must also be re-matched. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an adjustable structure for fixing a tuning liquid three-column star-shaped damper of a wind power tower.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is as follows:

[0014] Furthermore, the horizontal frame and the vertical frame are both provided with reinforcing ribs for improving the overall rigidity of the three-way fixing bracket.

[0015] Furthermore, a first anti-scratch layer is laid on the bottom of the cross frame to prevent the cross frame from being scratched against the top of the three-way prismatic water tank.

[0019] Furthermore, a force-bearing plate is laid in the arc-shaped groove to expand the contact area between the arc-shaped groove and the corresponding sub-pipeline, so that the force limiting of the corresponding sub-pipeline can be better performed.

[0020] Furthermore, a second anti-scratch layer is provided on a side of the load-bearing plate away from the arc-shaped groove to prevent the load-bearing plate from being scratched against the corresponding sub-pipeline.

[0021] Furthermore, the first adapting and adjusting module and the second adapting and adjusting module each include a connecting piece and an adjusting bolt group;

[0022] In the first adapting and adjusting module, the corresponding adjusting bolt group is connected to the three-way fixing bracket through the corresponding connecting piece;

[0024] Furthermore, the adjusting bolt assembly includes a bolt, a first nut, a second nut and a stud with an internal thread;

[0025] In the first adapting and adjusting module, the stud in the corresponding adjusting bolt group is nested in the lower platform, and the bolt passes through the connecting piece and is threadedly connected to the stud; the first nut and the second nut are both threadedly connected to the bolt, and the two are respectively placed on both sides of the connecting piece;

[0026] In the second adaptation adjustment module, the stud in the corresponding adjustment bolt group is arranged on the inner wall of the tower, and the bolt passes through the connecting piece and is threadedly connected to the stud; the first nut and the second nut are both threadedly connected to the bolt, and the two are respectively placed on both sides of the connecting piece.

[0027] Compared with the existing technology, the principles and advantages of this technical solution are as follows:

[0028] In this technical solution, the three-way prismatic water tank is limited in the horizontal and vertical directions by cooperating with the three-way fixing bracket and the first adaptation and adjustment module, and the corresponding sub-pipe is limited in the horizontal direction by cooperating with the sub-pipe fixing bracket and the corresponding second adaptation and adjustment module. This can avoid multi-dimensional vibration of the wind tower or collision between the damper and the inner wall of the tower when the wind tower is transported in a lying state, and can avoid the damper from being separated from the original installation position when the wind tower with the damper installed needs to be flipped over during the manufacturing process.

[0029] Moreover, by adjusting the first adaption and adjustment module and the second adaption and adjustment module, the three-way fixing bracket can be coordinated with the first adaption and adjustment module, and the sub-pipe fixing bracket can be coordinated with the corresponding second adaption and adjustment module to adapt to wind turbine towers with different inner diameters. There is no need to find the corresponding fixing components based on the diameters of the tower at different heights, and there is no need to find the corresponding size of fixing bracket based on the height of the three-way prismatic water tank in the middle of the damper after installation. This greatly reduces the workload of the installers and helps improve installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention will be further described below in conjunction with specific embodiments:

[0040] The three-way fixed bracket 1 is connected to the lower platform through the first adaptation and adjustment module 3, and cooperates with the first adaptation and adjustment module 3 to limit the three-way prismatic water tank 5; the sub-pipeline fixed bracket 2 is connected to the inner wall of the tower through the corresponding second adaptation and adjustment module 4, and cooperates with the second adaptation and adjustment module 4 to limit the corresponding sub-pipeline 6.

[0041] Specifically, in this embodiment, the three-way fixing bracket 1 includes a horizontal frame 8 for limiting the vertical position of the three-way prismatic water tank 5 and a vertical frame 7 for limiting the horizontal position of the three-way prismatic water tank 5; the vertical frame 7 is respectively arranged in three directions of the horizontal frame 8, and the top of the vertical frame 7 is connected to the horizontal frame 8; the first adaptation and adjustment module 3 is arranged at the bottom of the vertical frame 7.

[0042] The horizontal frame 8 and the vertical frame 7 are both provided with reinforcing ribs 9 for improving the rigidity of the three-way fixing bracket 1. The bottom of the horizontal frame 8 is paved with a first anti-scratch layer to prevent the horizontal frame 8 from scratching the top of the three-way prismatic water tank 5.

[0043] Specifically, in this embodiment, the sub-pipe fixing bracket 2 has a U-shaped structure, with a plate 10 disposed at the bottom inner side of the U-shape. This plate 10 has an arc-shaped groove 11, within which a force-bearing plate 12 is placed. This expands the contact area between the arc-shaped groove 11 and the corresponding sub-pipe 6, thereby better limiting the force applied to the corresponding sub-pipe 6. A second anti-scratch layer 13 is provided on the side of the force-bearing plate 12 facing away from the arc-shaped groove 11 to prevent scratches between the force-bearing plate 12 and the corresponding sub-pipe 6. A second adaptor and adjustment module 4 is disposed on either side of the U-shaped opening of the sub-pipe fixing bracket 2.

[0044] Specifically, in this embodiment, the first adaptation and adjustment module 3 and the second adaptation and adjustment module 4 both include a connecting piece 18 and an adjustment bolt group; in the first adaptation and adjustment module 3, the corresponding adjustment bolt group is connected to the three-way fixing bracket 1 through the corresponding connecting piece 18; in the second adaptation and adjustment module 4, the corresponding adjustment bolt group is connected to the corresponding sub-pipe fixing bracket 2 through the corresponding connecting piece 18.

[0045] Specifically, in this embodiment, the adjusting bolt group in the first adapting and adjusting module 3 and the adjusting bolt group in the second adapting and adjusting module 4 both include a bolt 14, a first nut 15, a second nut 16, and a stud 17 with an internal thread;

[0046] In the first adapting and adjusting module 3, the stud 17 in the corresponding adjusting bolt group is nested in the lower platform, and the bolt 14 passes through the connecting piece 18 and is threadedly connected to the stud 17; the first nut 15 and the second nut 16 are both threadedly connected to the bolt 14, and the two are respectively placed on both sides of the connecting piece 18;

[0047] In the second adaptation adjustment module 4, the stud 17 in the corresponding adjustment bolt group is welded to the inner wall of the tower, and the bolt 14 passes through the connecting piece 18 and is threadedly connected to the stud 17; the first nut 15 and the second nut 16 are both threadedly connected to the bolt 14, and the two are respectively placed on both sides of the connecting piece 18.

[0048] In the first adaptation and adjustment module 3, by loosening the corresponding first nut 15 and second nut 16, the three-way fixing bracket is adjusted to move along the length direction of the corresponding bolt 14 to adapt to the height of the three-way prismatic water tank after installation. After the displacement of the three-way fixing bracket is completed, the corresponding first nut 15 and second nut 16 are tightened.

[0049] In the second adaptation and adjustment module 4, by loosening the corresponding first nut 15 and the second nut 16, the sub-pipe fixing bracket is adjusted to move along the length direction of the corresponding bolt 14 to adapt to the tower diameter that changes with the tower height. After the displacement of the sub-pipe fixing bracket is completed, the corresponding first nut 15 and the second nut 16 are tightened.

[0050] In this embodiment, the three-way prismatic water tank 5 is limited in the horizontal and vertical directions by cooperating with the three-way fixing bracket 1 and the first adapting and adjusting module 3, and the corresponding sub-pipe 6 is limited in the horizontal direction by cooperating with the sub-pipe fixing bracket 2 and the corresponding second adapting and adjusting module 4. This can avoid multi-dimensional vibration of the wind tower or collision between the damper and the inner wall of the tower when the wind tower is transported in a lying state, and can avoid the damper from being separated from the original installation position when the wind tower with the damper installed needs to be flipped over during the manufacturing process.

[0051] Moreover, by adjusting the first adaptation and adjustment module 3 and the second adaptation and adjustment module 4, the three-way fixing bracket 1 can be coordinated with the first adaptation and adjustment module 3, and the sub-pipe fixing bracket 2 can be coordinated with the corresponding second adaptation and adjustment module 4 to adapt to wind towers with different inner diameters. There is no need to find corresponding fixing components based on the diameters of the tower at different heights, and there is no need to find fixing brackets of corresponding sizes based on the height of the three-way prismatic water tank 5 in the middle of the damper after installation. This greatly reduces the workload of the installers and helps improve installation efficiency.

[0052] The above-described embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any changes made based on the shape and principle of the present invention should be included in the scope of protection of the present invention.
