Description

Technical Field

[0001] This utility model relates to the field of support frame technology, and in particular to an anti-vibration support frame for ultra-high altitude towers. Background Technology

[0002] In ultra-high altitude regions, the tower, as a key supporting structure in wind power generation projects, needs to withstand extremely complex operating conditions. These areas are constantly exposed to strong winds, low temperatures, frequent air pressure changes, and vibrations caused by geological activity, posing a significant challenge to the stability of the tower. Once the tower is displaced, deformed, or even damaged due to vibration, it will not only lead to a significant decrease in power generation efficiency but may also cause serious safety accidents.

[0003] Currently, most existing tower support frames on the market are designed for conventional environments, and their vibration resistance performance is insufficient to meet the special needs of ultra-high altitude areas. Some support frames have simple structures that cannot effectively absorb and disperse the energy generated by complex vibrations; others have not fully considered the low temperature and strong wind environment of ultra-high altitudes in their material selection, resulting in a decline in material performance and a weakening of vibration resistance. In view of this, this utility model proposes an ultra-high altitude tower vibration-resistant support frame. Utility Model Content

[0004] The purpose of this invention is to address the problems in the background technology where existing tower support frames are not adapted to extreme working conditions such as strong winds, low temperatures, and complex vibrations in ultra-high altitude areas, resulting in insufficient vibration resistance and easy material failure, making it difficult to ensure the stability of the tower. This invention proposes an ultra-high altitude tower vibration-resistant support frame.

[0005] The technical solution of this utility model is as follows: an anti-vibration support frame for ultra-high altitude towers, including an inner support frame; multiple sets of connecting rings disposed on the outer side of the inner support frame, with flanges installed on the sides of the connecting rings, and the flanges being bolted to the tower; a connecting assembly installed in the inner support frame, the connecting assembly being used to connect multiple tower sections; and a buffer mechanism disposed on the connecting assembly, the buffer mechanism being used to improve the load-bearing capacity.

[0006] Optionally, the inner support frame includes multiple sets of uprights, and multiple sets of connecting rods connect adjacent sets of uprights. The inner support frame is in the shape of a conical tower, which is smaller at the top and larger at the bottom.

[0007] Optionally, the inner support frame is a segmented design, with adjacent segments connected by bolts.

[0008] Optionally, the connecting component is located at the center of the inner support frame on the synchronizing rod, and multiple sets of fixing blocks are fixedly connected to the synchronizing rod. The fixing blocks are regular polygons, and the multiple sets of fixing blocks are located at both ends of each tower section.

[0009] Optionally, each side of the fixing block is fixedly connected to a mounting block, and a movable rod is fixedly connected to the mounting block on the side away from the fixing block, with one end of the movable rod fixedly connected to a connecting ring.

[0010] Optionally, the synchronizing rod is segmented, with sleeves installed at the joints of adjacent segments.

[0011] Optionally, the buffer mechanism includes a synchronization block sleeved and installed on the outer ring of the moving rod. A sliding block is fixedly connected to the side of the synchronization block near the connecting rod. Multiple sets of limiting rods are slidably connected in the sliding block. Both ends of the multiple sets of limiting rods are fixedly connected to a fixing plate. Both sets of fixing plates are fixedly connected to the connecting rod. Two sets of springs are sleeved and installed on the outer ring of the limiting rod. The two sets of springs are symmetrically arranged on both sides of the sliding block.

[0012] Optionally, a damping sleeve is installed in some of the synchronization blocks. The damping sleeve is fitted onto the outer ring of the moving rod and is made of silicone rubber.

[0013] Optionally, the spring is made of titanium alloy.

[0014] Optionally, the connecting assembly, other components of the buffer mechanism, as well as the inner support frame and connecting ring, are all made of Q355D / E steel.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] This utility model adopts a segmented design of the internal support frame, with adjacent sections connected by bolts, which greatly reduces the unit volume and effectively solves the problem of transportation difficulties in ultra-high altitude areas. At the same time, the internal support frame is a conical tower shape with a smaller top and a larger bottom, matching the shape of the tower. With the connecting ring and flange that fit the outer side of the tower and the inner wall of the tower, it is easy to accurately position the tower and quickly install it, significantly improving construction efficiency.

[0017] Furthermore, the buffer mechanism composed of springs and damping sleeves achieves efficient buffering and energy dissipation of tower vibration. The titanium alloy springs are lightweight, have high fatigue limit and excellent weather resistance, while the silicone rubber damping sleeves are adaptable to a wide temperature range and have strong anti-aging properties. The two work together to both accumulate elastic force through spring compression to buffer vibration and consume the elastic force released by the spring through the damping sleeve, thus avoiding reciprocating vibration of the connecting ring and effectively ensuring the structural stability of the tower under complex working conditions such as ultra-high altitude and strong winds.

[0018] In summary, this utility model effectively overcomes the shortcomings of existing support frames under extreme working conditions at ultra-high altitudes, ensures stable tower operation, reduces safety risks, and improves power generation efficiency. Attached Figure Description

[0033] Example

[0034] like Figure 1 and Figure 2 As shown, this utility model proposes an anti-vibration support frame for ultra-high altitude towers, including an inner support frame 1. The inner support frame 1 includes multiple sets of uprights 11, and multiple sets of connecting rods 12 connect adjacent sets of uprights 11. The inner support frame 1 is a conical tower shape, wider at the bottom and narrower at the top, matching the shape of the tower, facilitating tower installation, and improving structural strength. The inner support frame 1 is a segmented design, with adjacent segments connected by bolts, reducing unit volume, improving transportation convenience, and facilitating tower installation.

[0035] Furthermore, the aforementioned support frame also includes multiple sets of connecting rings 2 disposed on the outer side of the inner support frame 1. The connecting rings 2 fit snugly against the inner wall of the tower, facilitating positioning during tower installation. Flanges 21 are mounted on the sides of the connecting rings 2, and the flanges 21 are bolted to the tower to secure it.

[0036] Specifically, as shown in the figure, the support frame includes a connecting assembly 3 installed in the inner support frame 1. The connecting assembly 3 is used to connect multiple tower sections. The connecting assembly 3 is located at the center of the inner support frame 1 via a synchronizing rod 31. Multiple sets of fixing blocks 32 are fixedly connected to the synchronizing rod 31. The fixing blocks 32 are regular polygons, and multiple faces of the fixing blocks 32 correspond to multiple faces formed by the uprights 11. The multiple sets of fixing blocks 32 are located at both ends of each tower section, facilitating connection with the tower section via the connecting assembly 3. Each side of the fixing block 32 is fixedly connected to an installation block 33. A moving rod 34 is fixedly connected to the side of the installation block 33 away from the fixing block 32. One end of the moving rod 34 is fixedly connected to a connecting ring 2. The moving rod 34 connects the connecting ring 2 and the sleeve 35, so that when the tower vibrates and drives the connecting ring 2 to move, the connecting ring 2 will drive the connecting assembly 3 to move synchronously. Synchronous rod 31 is segmented, and sleeves 35 are installed at the joints of adjacent segments. Through synchronous rod 31 and sleeves 35, the segmented tower can be connected into a whole.

[0037] Furthermore, the aforementioned support frame includes a buffer mechanism 4 mounted on the connecting assembly 3, which enhances the load-bearing capacity. The buffer mechanism 4 includes a synchronizing block 41 sleeved and installed on the outer ring of the moving rod 34. When the moving direction of the connecting ring 2 is the same as the length of the moving rod 34, it causes the moving rod 34 to slide within the synchronizing block 41. When the moving direction of the connecting ring 2 is different from the length direction of the moving rod 34, the moving rod 34 causes the synchronizing block 41 to move synchronously. A sliding block 42 is fixedly connected to the side of the synchronizing block 41 near the connecting rod 12, and the sliding block 42 moves synchronously with the synchronizing block 41. Two sets of limiting rods 43 are slidably connected within the sliding block 42. Both ends of the two sets of limiting rods 43 are fixedly connected to a fixing plate 44, and both sets of fixing plates 44 are fixedly connected to the connecting rod 12. The fixed positions of the limiting rods 43 and the fixing plates 44 ensure smooth movement of the sliding block 42 and, in conjunction with the moving rod 34, provide support for the connecting ring 2. Two sets of springs 45 are fitted around the outer ring of the limiting rod 43. The two sets of springs 45 are symmetrically arranged on both sides of the sliding block 42. The springs 45 are used to accumulate elastic force when the sliding block 42 moves, thereby buffering vibration. A damping sleeve 46 is installed in part of the synchronization block 41. The damping sleeve 46 is fitted around the outer ring of the moving rod 34. The damping sleeve 46 consumes the elastic force accumulated by the springs 45, preventing the springs 45 from releasing their elastic force and causing the connecting ring 2 to reciprocate.

[0038] Spring 45 is made of titanium alloy with a density of 4.5 g / cm³. 3Achieving lightweight construction reduces transportation and installation difficulty; fatigue limit ≥700MPa; excellent UV resistance in ultra-high altitude areas; and a stable natural oxide film on the surface. The damping sleeve 46 is made of silicone rubber, with a temperature range of -60℃ to 200℃. After 500 hours of UV aging, its tensile strength retention rate is ≥85%, and it has low surface energy, resisting dust adhesion. The connecting assembly 3, other components of the buffer mechanism 4, as well as the inner support frame 1 and connecting ring 2, are all made of Q355D / E steel with a yield strength of 355MPa to 460MPa. Its high tensile strength allows it to withstand alternating loads caused by strong winds in ultra-high altitude areas, reducing structural deformation. It maintains impact toughness in environments ranging from -20℃ to -40℃, preventing low-temperature brittle fracture.

[0039] In this embodiment, the lowest section of the inner support frame 1 is first fixed, on which a buffer mechanism 4 and some connecting components 3 are installed. The lowest section of the tower is then installed onto the inner support frame 1, and the inner flange of the tower and the flange plate 21 are connected by bolts. Next, the upper sections of the inner support frame 1 and the tower sections are installed sequentially. When two adjacent sections of the inner support frame 1 are joined, they are connected by sleeves 35 to the two sets of synchronous rods 31 at their closest ends and welded together. When the tower vibrates, the connecting ring 2 drives the moving rod 34 to move irregularly. At this time, part of the moving rod 34 drives the synchronous block 41 and the sliding block 42 to move and compress the spring 45. When the spring 45 releases its elastic force, part of the moving rod 34 slides in the synchronous block 41. The damping force generated by the damping sleeve 46 prevents the periodic vibration caused by the release of the spring force of the spring 45, quickly stabilizing the vibration of the connecting ring 2 and preventing the vibration from affecting the structure.

[0040] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
