A highly stable power tower

Abstract

This invention relates to the field of power tower technology, specifically disclosing a highly stable power tower, comprising a power tower body, a leveling device, a leveling rod, ropes, and tie rods. By setting up the leveling device and connecting the leveling rod to the top of the power tower body, the leveling rod, which is subject to the greatest wind disturbance at the top, deflects around its connection point with the support. This causes the lower end of the leveling rod to drive an adjustment mechanism, tightening the ropes and leveling the power tower body. This solves the problem in existing technologies where power towers are easily affected by wind and sway, leading to structural instability. It achieves the effect of making the power tower less susceptible to wind influence, facilitating structural adjustment, and improving stability.

[0009] Furthermore, a third spherical seat is provided at the center of the bracket; a third adjusting ball is provided on the aligning rod; the third adjusting ball is connected to the third spherical seat.

[0010] Furthermore, the support includes four legs disposed within the power tower body and mounting rings disposed on the top of the four legs; the third spherical seat is located at the center of the mounting ring, and the third spherical seat is fixedly connected to the mounting ring by a mounting rod.

[0015] The technical solutions provided in this application embodiment have at least the following technical effects or advantages:

[0016] 1. Because a leveling device is installed inside the power tower body, the top of the power tower body is easily affected by wind and may sway. The leveling device can automatically adjust the position of the top of the power tower body, which effectively solves the problem of power towers being easily affected by wind and swaying, resulting in structural instability in the existing technology.

[0026] This application discloses a highly stable power tower. By setting up a leveling device 2, a leveling rod 5 is connected and fixed to the top of the power tower body 1. Since the top of the tower is most affected by wind disturbance, the leveling rod 5 is driven to deflect around the connection point with the support 3. This causes the lower end of the leveling rod 5 to drive the adjustment mechanism 7, which tightens the rope 4 and adjusts the power tower body 1. This solves the problem in the prior art where power towers are easily affected by wind and become unstable. It achieves the effect of making the power tower less affected by wind, facilitating the adjustment of its own structure, and improving stability.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1 , Figure 2 A highly stable power tower includes a power tower body 1 and a leveling device 2. The outer diameter of the power tower body 1 decreases from bottom to top. Each of the four legs at the bottom of the power tower body 1 is fixedly equipped with a gravity block 11, which is buried deep in the ground to enhance the support and stability of the power tower body 1. The leveling device 2 is installed on the inner and outer sides of the power tower body 1 to adjust and level the power tower body 1 in a timely manner, thereby improving the structural stability of the power tower body 1.

[0029] Reference Figure 2 , Figure 3 and Figure 4The leveling device 2 includes a support 3, a rope 4, a leveling rod 5, a tie rod 6, and an adjustment mechanism 7. The support 3 includes a fixing block 31, support legs 32, and an mounting ring 33. The fixing block 31 is buried in the ground. Four support legs 32 are evenly arranged, and the bottom of each support leg 32 is fixedly connected to a fixing block 31. The mounting ring 33 is fixedly installed on the upper end of the four support legs 32, and the mounting ring 33 is located between the top and middle of the power tower body 1. A reinforcing rod 34 is fixedly connected between the support legs 32 and the inner side of the power tower body 1. Four reinforcing rods 34 are evenly arranged around the support legs 32, and the reinforcing rods 34 are inclined. The end of the reinforcing rod 34 connected to the power tower body 1 is higher than the end of the reinforcing rod 34 connected to the support leg 32, which is used to enhance the reinforcement of the power tower body 1. The inclined reinforcing rod 34 forms an irregular shape with the power tower body 1, which strengthens the support of the power tower body 1 and improves the stability of the power tower body 1. The adjusting mechanism 7 is located at the bottom of the power tower body 1, and the lower end of the sizing rod 5 is connected to the adjusting mechanism 7. A third spherical seat 35 is installed inside the mounting ring 33. The third spherical seat 35 is located at the center of the mounting ring 33, and the upper and lower end faces of the third spherical seat 35 are through structures. The third spherical seat 35 is fixedly connected to the mounting ring 33 by a mounting rod. A third adjusting ball 51 is fixedly installed on the sizing rod 5. The third adjusting ball 51 is connected inside the third spherical seat 35 and can swing around the connection point of the third spherical seat 35 as the center of rotation. It can convert the tilting force on the power tower body 1 into the force on the sizing rod 5, and then drive the adjusting mechanism 7 through the sizing rod 5 to act on the power tower body 1, so that the top of the power tower body 1 can be sizing. The upper end of the aligning rod 5 is fixedly connected to the inner top of the power tower body 1, i.e., fixed to the tower tip of the power tower body 1. This effectively transmits the force on the tower tip of the power tower body 1 to the aligning rod 5. Four ropes 4 are arranged around the perimeter of the power tower body 1. An adjusting rod 12 is fixedly installed around the perimeter of the power tower body 1. The four adjusting rods 12 correspond one-to-one with the four ropes 4. The adjusting rods 12 are horizontally positioned above the ball connection between the aligning rod 5 and the support 3, and close to the mounting ring 33. The upper end of the rope 4 is fixedly connected to the end of the adjusting rod 12 passing through the power tower body 1, and the lower end of the rope 4 is fixed to the ground. The rope 4 near the ground is connected to the adjusting mechanism 7 via a pull rod 6. This allows the disturbance force on the power tower body 1 at the tower tip to be transmitted to the aligning rod 5. The aligning rod 5 drives the adjusting mechanism 7, which in turn drives the pull rod 6 to tighten the rope 4, thus aligning and adjusting the power tower body 1.To further reinforce the support of the sizing rod 5 to the power tower body 1, the other end of the adjusting rod 12 extends through the power tower body 1 and into its interior. The end of the adjusting rod 12 is spaced apart from the side wall of the sizing rod 5. To improve the overall connection stability, a limiting ring 13 is fixedly installed between the ends of the four adjusting rods 12 located inside the power tower body 1. The inner side wall of the limiting ring 13 is spaced apart from the side wall of the sizing rod 5, allowing the sizing rod 5 to have a certain range of movement. When the tower tip of the power tower body 1 causes the sizing rod 5 to deflect, the limiting ring 13 can limit the sizing rod 5, thereby strengthening the power tower body 1. More preferably, the upper end of the adjusting rod 12 is fixedly connected to the upper end of the support 3 via the upright 36, and the upper end of the straightening rod 5 is fixedly connected to the top of the power tower body 1. When the top of the power tower body 1 experiences extreme deflection, the adjusting rod 12, the straightening rod 5, and the power tower body 1 form a triangular structure, which has a high stability function and can further strengthen the support for the top of the power tower body 1, improving the overall structural strength. When subjected to wind disturbance or impact, the top of the power tower body 1 swings the most. The straightening rod 5 has a certain deformation capacity, and the straightening rod 5 is ball-connected to the support 3, causing the straightening rod 5 to be deflected by the top of the power tower body 1. When the upper end of the straightening rod 5 deflects to one side, the rope 4 on that side will loosen, and the lower end of the straightening rod 5 deflects to the opposite side, driving the adjusting mechanism 7 to operate. This causes the adjusting mechanism 7 to tighten the rope 4 in the opposite direction, thereby adjusting the power tower body 1 and restoring it to its normal state.

[0030] Reference Figure 2 , Figure 5Four ropes 4 are installed around the power tower body 1. The ropes 4 are inclined in the direction of inclination from bottom to top towards the power tower body 1. Rope 4 includes a first connecting rope 41, a first connecting disc 42, a stud 43, a second connecting disc 44, and a second connecting rope 45. A fixing seat 46 is fixedly installed at the lower end of the first connecting rope 41. The fixing seat 46 includes a positioning block 461, a positioning post 462, and positioning barbs 463. The diameter of the positioning block 461 is larger than the diameter of the positioning post 462, and the positioning post 462 is inserted into and fixed in the ground. The positioning block 461 is fixed to the upper end of the positioning post 462 and fits against the ground. Multiple positioning barbs 463 are fixedly installed on the side wall of the positioning post 462 near the bottom and are evenly arranged along the circumference of the positioning post 462 to strengthen the connection with the ground. The lower end of the first connecting rope 41 is fixed to the upper end face of the positioning block 461. The first connecting disc 42 is fixedly installed at the upper end of the first connecting rope 41. An opening is made on the end face of the first connecting disc 42 near the edge. A series of threaded holes are provided. The lower end of the second connecting rope 45 is fixedly connected to the second connecting disc 44, and the upper end of the second connecting rope 45 is fixedly connected to the end of the adjusting rod 12. The first connecting disc 42 and the second connecting disc 44 are fixedly connected on opposite sides by a connecting spring 47. Multiple studs 43 are fixedly installed on the side of the second connecting disc 44 near the first connecting disc 42. The multiple studs 43 are evenly distributed around the circumference of the connecting spring 47. The other end of the stud 43 passes through the threaded hole and is threadedly connected to the threaded hole. The lower end of the stud 43 is threadedly connected to a nut, so that the first connecting rope 41 and the second connecting rope 45 are connected and fixed. The studs 43 are supported by a rigid material, preferably steel. By setting the studs 43, the length of the rope 4 can be adjusted, the tension of the rope 4 can be adjusted in time, and the power tower body 1 can be tightened.

[0031] Reference Figure 2 , Figure 6The adjustment mechanism 7 includes a first spherical seat 71, a first adjusting ball 72, a first fixing rod 73, a connecting frame 74, a second spherical seat 75, and a second adjusting ball 76. A base 78 is fixedly installed at the bottom of the bracket 3 and in contact with the ground. The first spherical seat 71 is fixedly installed at the center of the base 78, with the opening of the first spherical seat 71 facing directly upward. The first adjusting ball 72 is ball-connected to the first spherical seat 71. The first fixing rod 73 is vertically fixed above the first adjusting ball 72. The second spherical seat 75 is fixedly installed at the upper end of the first fixing rod 73. The second adjusting ball 76 is ball-connected to the second spherical seat 75. A second fixing rod 77 is fixedly connected to the second adjusting ball 76. A movable groove 52 is provided at the bottom of the aligning rod 5. The movable groove 52 is vertically arranged, and the depth of the movable groove 52 is greater than the height of the second fixing rod 77. The second fixing rod 77 is inserted into the movable groove 52 and slidably connected to the movable groove 52. Without external force, the extended centerline of the aligning rod 5 passes through the centers of the first spherical seat 71, the first adjusting ball 72, the first fixed rod 73, the second spherical seat 75, the second adjusting ball 76, the first fixed rod 73, and the second fixed rod 77, and is vertical, consistent with the height direction of the power tower body 1. A connecting frame 74 is fixedly installed on the first fixed rod 73, located between the first adjusting ball 72 and the second spherical seat 75. The connecting frame 74 includes a fixing ring 741 and connecting rods 742. The fixing ring 741 is fixedly installed on the first fixed rod 73. Four connecting rods 742 are evenly distributed around the circumference of the fixing ring 741. The connecting rods 742 are horizontally positioned, with one end fixed to the circumference of the fixing ring 741, and the other end extending outward through the power tower body 1. The connecting rods 742 are connected to the power tower body 1. The main body 1 is movable and coordinated, with connecting rods 742 and pull rods 6 corresponding one-to-one. One end of the pull rod 6 is fixedly connected to the end of the corresponding connecting rod 742 extending out of the main body 1 of the power tower. The other end of the pull rod 6 is fixedly installed with a sliding sleeve 61. The length direction of the sliding sleeve 61 is consistent with the length direction of the pull rod 6. A limiting groove is formed on the sliding sleeve 61, which is set along the length direction of the sliding sleeve 61. The sliding sleeve 61 is sleeved on the rope 4, and the rope 4 slides in cooperation with the limiting groove. A positioning part 48 is fixedly installed on the rope 4, so that the sliding sleeve 61 is located in the positioning part 48. Specifically, the positioning part 48 is a positioning ring piece, which is fixedly installed on the second connecting rope 45 near the first connecting rope 41, and the positioning part 48 is close to the second connecting disc 44. The sliding sleeve 61 is located between the positioning part 48 and the second connecting disc 44, which can better limit the sliding direction of the sliding sleeve 61, so that the pull rod 6 can better tighten the rope 4, thereby improving the installation stability of the main body 1 of the power tower.

[0032] The working principle of this embodiment is as follows: when the power tower body 1 is subjected to wind disturbance or impact from foreign objects, the force at its top is the greatest. To facilitate the analysis of the force on the power tower body 1, it is assumed that the top of the power tower body 1 is subjected to a wind force from right to left.

[0033] The tip of the power tower body 1 deflects from right to left and downward. Since the top of the sizing rod 5 is fixedly connected to the tip of the power tower body 1, it causes the sizing rod 5 to deflect around the third spherical seat 35. The upper end of the sizing rod 5 deflects in the same direction as the tip of the power tower body 1, while the lower end deflects in the opposite direction. Because the lower end of the sizing rod 5 is inserted into the second fixed rod 77, when the sizing rod 5 deflects from right to left and upward, it causes... The second fixed rod 77 deflects and has a certain deformation capacity. When the second fixed rod 77 deflects, it exerts a force on the second spherical seat 75. The second spherical seat 75 and the first adjusting ball 72 are fixedly connected through the first fixed rod 73. The first adjusting ball 72 is restricted by the first spherical seat 71 fixed to the ground, so that the second spherical seat 75, the first fixed rod 73 and the first adjusting ball 72 deflect from left to right and downward with the first spherical seat 71 as the rotation center.

[0034] When the first fixed rod 73 deflects from left to right and downward, it causes the connecting frame 74 to deflect from left to right and downward. Since both ends of the connecting frame 74 are connected to tie rods 6, the left side of the connecting frame 74 rotates upward and the right side rotates downward. Under the action of the tie rod 6 on the left side of the connecting frame 74, the sliding sleeve 61 on the left side moves obliquely upward along the rope 4, while the tie rod 6 on the right side of the connecting frame 74 drives the sliding sleeve 61 on the right side to pull towards the bottom of the power tower body 1, tightening the rope 4 on the side opposite to the deflection direction of the power tower body 1. Therefore, the power tower body 1 can be straightened in time, improving the overall stability of the power tower body 1 and strengthening the strength of the power tower body 1.

[0035] In summary, when the power tower body 1 is subjected to wind force from one side, causing the tower tip to deflect, the adjusting mechanism 7 is activated by the straightening rod 5, which tightens the rope 4 on the side opposite to the wind force, thereby straightening the power tower body 1 in a timely manner.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present application, based on the technical solution and concept of the present application, should be covered within the scope of protection of the present application.
