Description

Technical Field

[0001] This invention relates to the field of tower vibration reduction, and more particularly to a self-adjusting damping prestressed vibration reduction system for tower structures. Background Technology

[0002] Tall tower structures, such as single-tube communication towers and tall light poles, exhibit lateral vibration under wind loads due to their relatively weak lateral stiffness. In design, the horizontal displacement of the tower top under wind loads is often the controlling factor. The conventional method is to increase the tower diameter or wall thickness to improve tower stiffness and control top displacement, but this increases the cost of the tower. For existing towers, increasing stiffness is even more difficult; therefore, external reinforcement devices are more suitable after the tower construction is complete.

[0003] For example, publication number "CN2589551" discloses a "single-tube tower displacement control vibration reduction device," which is installed inside the tower body of a single-tube tower and consists of a weight, an elastic mechanism, and a damper. The weight is fixed to the center of the tower body's cross-section by two groups of elastic mechanisms, each group consisting of at least three elastic mechanisms. Damperes are also installed or connected in series on the elastic mechanisms. However, in practical applications, because the vibration reduction device is directly placed at the top of the tower, the weight at the top of the tower increases, reducing overall stability. Due to the grouped arrangement, the overall coordination is poor, and it also places a large load on the top of the tower even in non-vibration conditions. Summary of the Invention

[0004] In response to the problems mentioned in the background art, such as the reduction of tower stability, poor coordination, and increased tower top load caused by existing vibration damping devices, this invention provides a self-adjusting damping prestressed vibration damping system for tower structures. This system can reduce the lateral deformation of the tower while ensuring its stability, improve the overall coordination, and generate pull-back force and damping through the movement of the counterweight components and self-adjusting dampers, thereby reducing the lateral vibration amplitude of the tower body, improving the tower body's stiffness against lateral deformation, enhancing the tower body's load-bearing capacity and safety, and maintaining the pretension of the connecting wires through the counterweight components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A self-adjusting damping prestressed vibration reduction system for a tower structure includes the following components: a tower body comprising a tower top and a tower base; a self-adjusting damper fixedly connected to the tower base; a connecting wire disposed inside the tower body, one end of which is connected to the tower top, and the other end connected to a counterweight assembly; and a counterweight assembly whose end away from the connecting wire is connected to the self-adjusting damper. By connecting the counterweight assembly to the connecting wire, a pre-tension force can be maintained, while the other end, connected to the self-adjusting damper, applies a restoring force to the self-adjusting damper after the tower body's swaying stops, accelerating the recovery of the self-adjusting damper and the straightening of the connecting wire. This prevents the tower body from swaying again, and if the sway amplitude is not as high as before, the system will not be able to generate a return force due to incomplete recovery. Furthermore, the generated return force is adaptively variable with the damping, and the return force is generated through the self-adjusting damper during vibration reduction, thereby preventing deformation of the connecting wire and increasing its service life. Meanwhile, the connecting lines are located inside the tower body, which is generally a hollow structure. When the tower body sways in different directions, the connecting lines are pulled, lifting the counterweight components and pulling the self-adjusting damper, thereby generating a pull-back force to counteract the swaying in each direction. By setting up a single connecting line, the swaying problem in each direction can be solved, avoiding the need for multiple connecting lines, reducing costs. Furthermore, the combination of the self-adjusting damper, counterweight components, and connecting lines improves the overall integration of the device, enhancing the synergy of the entire tower body, strengthening the connection between the tower base and the tower top, and thus improving stability.

[0007] Preferably, the self-adjusting damper includes a bottom chamber containing a viscous fluid. A piston assembly is movably connected to the bottom chamber, and a storage chamber is connected to the end of the bottom chamber near the counterweight assembly. A partition is connected to the bottom chamber, and the partition has damping through-holes connecting the bottom chamber and the storage chamber. The bottom chamber contains the viscous fluid, and the piston assembly can slide up and down within the bottom chamber. The piston assembly is connected to the counterweight assembly. After the tower tilts or sways, the connecting line lifts the counterweight assembly and the piston assembly, pushing the viscous fluid through the damping through-holes. Due to the damping effect generated by the throttling of the small holes in the damping through-holes, the viscous fluid can pass through the damping through-holes, but a reaction force is generated to limit the swaying of the tower. In practical applications, different damping effects are produced by setting small holes of different sizes and numbers on each layer of the partition. It has a long service life; the viscous fluid can produce a damping effect as long as it exists in the bottom chamber, and it will not interfere with other components or cause friction. It can be reused repeatedly without considering the fatigue limit of the viscous fluid itself.

[0008] Preferably, the reservoir includes several reservoir compartments, each separated by a partition with damping through-holes. The reservoir also includes multiple reservoir compartments, each separated by partitions with damping through-holes, allowing for segmented generation of different levels of damping force. After the reservoir compartment near the bottom chamber is filled with viscous fluid, as the piston continues to move, the viscous fluid must pass through the damping through-holes between the bottom chamber and the reservoir compartment, as well as between two reservoir compartments, thus increasing damping. Similarly, in practical applications, different numbers and volumes of reservoir compartments can be used to obtain varying degrees of increasing damping force, and the timing of damping force changes can be controlled.

[0009] Preferably, a pressurization assembly is connected to the storage chamber, and the piston assembly includes a sensor assembly. When the sensor assembly detects that the piston assembly has reached its stroke limit, the pressurization assembly can inject compressed air into the storage chamber. Since the damping force generated by the viscous fluid comes entirely from the stroke of the piston assembly, when the piston assembly reaches its maximum stroke, it will abut against the partition. Therefore, a stroke limit is set for the sensor assembly. When the stroke limit is reached, the piston assembly approaches the partition, but there is still a certain amount of viscous fluid in the bottom chamber. At this time, compressed air is injected into the storage chamber through the pressurization assembly, thereby increasing the resistance in the storage chamber again, thus resisting the large-scale swaying of the tower. The pressurization assembly includes, but is not limited to, an air compressor, which can deliver the compressed air in the storage chamber when not in operation, and deliver compressed air when in operation, thereby controlling the flow of the viscous fluid.

[0010] Preferably, the sensor assembly includes a limit sensor with an elastic element connected to it. The end of the elastic element away from the limit sensor is connected to the piston assembly. The sensor assembly includes a limit sensor and an elastic element. When the limit sensor contacts the partition, it triggers the pressurization assembly. Subsequently, as the piston assembly rises again, it squeezes the elastic element, maintaining the limit sensor in contact with the partition. This ensures that pressurized air is continuously delivered. Furthermore, after the significant shaking of the tower body disappears, the piston assembly's over-limit movement ensures that the limit sensor remains in contact with the partition until the piston assembly returns to its stroke. This allows the pressurization assembly to continuously inject compressed air, helping the piston assembly quickly return to its stroke and preventing the piston assembly from failing to quickly reach its working state.

[0011] Preferably, the partition is provided with a one-way flow element. The one-way flow element on the partition can accelerate the backflow speed of the viscous fluid, and due to the one-way flow, the viscous fluid can only flow through the damping through hole when the piston assembly is lifted, ensuring the stability of the damping force.

[0012] Preferably, the one-way flow component includes a return hole on the partition. A one-way valve cover is hinged to the partition near the bottom compartment. When the piston assembly is raised, the viscous fluid pushes the one-way valve cover against the partition. When the piston assembly is lowered, the one-way valve cover can detach from the partition due to its own weight and the reverse push of the viscous fluid. When the one-way valve cover is located near the bottom compartment, it is pressurized by the upward-flowing viscous fluid and presses against the partition, preventing the viscous fluid from passing through the return hole. The tensile force provided by the connecting line can also be pressurized on the one-way valve cover by the viscous fluid, ensuring a tight fit. When the piston assembly retracts, the flow direction of the viscous fluid reverses, flowing through the return hole and pushing open the one-way valve cover, thus accelerating the return efficiency of the viscous fluid.

[0013] Preferably, the counterweight assembly includes a rigid connecting rod that is connected to the piston assembly. The connection between the rigid connecting rod and the piston assembly allows the counterweight assembly to directly apply pressure to the piston assembly, ensuring that the counterweight assembly consistently provides a restoring force during the piston assembly's retraction. The rigid connecting rod is hinged to the piston assembly, allowing it to adapt to certain deformations and facilitating installation. Furthermore, it effectively transmits the restoring force to the piston assembly even when the counterweight assembly wobbles or shifts.

[0014] Preferably, a plurality of limiters are connected to the inner wall of the tower body, each of which has a centroidal perforation. The connecting line passes through each centroidal perforation and connects to the counterweight assembly. The centroidal perforation is located on the centroidal line of the tower body. When the tower body sways or tilts, the connecting line at the centroidal perforation remains aligned with the centroidal line of the tower body, making the lifting effect of the connecting line on the counterweight assembly and piston assembly more significant. Without the constraint of the limiters, the connecting line would deviate, failing to provide effective tension, thus causing the device to malfunction.

[0015] Preferably, the spacing between the limiters is reduced from the base to the top of the tower. Since the deformation of the top region of the tower is greater than that of the bottom region, reducing the spacing between the limiters near the top of the tower allows the connecting lines to coincide as closely as possible with the centroid of the tower when the tower sways, thus ensuring a significant stretching effect on the connecting lines during swaying.

[0016] The beneficial effects of this invention are as follows:

[0017] (1) The counterweight component can provide pre-tension to the connecting line and restore force to the self-adjusting damper, thereby ensuring the stability and rapid response of the entire system. The connecting line is set inside the tower body to counteract the swaying of the tower body in all directions, so that it can be used for swaying in all directions through a single connecting line.

[0018] (2) Damping force is generated on viscous fluid through the damping through hole, and the damping force is gradually increased by setting up multi-level storage compartments. The damping force can be precisely controlled at the change node of the damping force, thereby improving the applicability and flexibility.

[0019] (3) The sensor assembly and pressurization assembly can resist greater shaking, protect the self-adjusting damper, avoid pressurization of the piston assembly, improve service life, and provide rapid response and improve the recovery force of the piston assembly.

[0020] (4) Setting a limiter can keep the connecting line as close as possible to the centroid of the tower, so that when the tower shakes, the connecting line can exert a more significant lift on the counterweight and piston components, thereby generating damping force and helping the tower to stabilize quickly.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] like Figure 1 The tower structure self-adjusting damping prestressed vibration reduction system shown includes the following components: tower body 1: including tower top 11 and tower base 12; self-adjusting damper 2: fixedly connected to tower base 12; connecting line 3: set inside tower body 1, one end of connecting line 3 is connected to tower top 11, and the other end is connected to counterweight assembly 4; counterweight assembly 4: the end of counterweight assembly 4 away from connecting line 3 is connected to self-adjusting damper 2.

[0032] By connecting the counterweight assembly 4 to the connecting line 3, a pre-tension force can be maintained for the connecting line 3. Simultaneously, the other end is connected to the self-adjusting damper 2. After the tower body 1 stops swaying, a restoring force can be applied to the self-adjusting damper 2, accelerating its recovery and the tautness of the connecting line 3. This prevents the tower body 1 from swaying again before the sway amplitude reaches the previous level, thus avoiding the inability to generate a pull-back force due to incomplete recovery. During vibration reduction, the pull-back force generated by the self-adjusting damper 2 prevents deformation of the connecting line 3, thereby increasing its service life. Furthermore, since the connecting line 3 is located inside the tower body 1, which has a hollow structure, it can pull the connecting line 3 when the tower body 1 sways in different directions, lifting the counterweight assembly 4 and pulling the self-adjusting damper 2, thereby generating a pull-back force to counteract swaying in all directions. By setting a single connecting line 3, the swaying problem in all directions can be solved, avoiding the need for multiple connecting lines 3 and reducing costs.

[0033] like Figure 2 , 3 As shown, the self-adjusting damper 2 includes a bottom chamber 21, in which a viscous fluid 22 is disposed. A piston assembly 23 is movably connected to the bottom chamber 21. The piston assembly 23 includes a piston rod 231 and a piston block 232. A storage chamber 24 is connected to one end of the bottom chamber 21 near the counterweight assembly 4. A partition 25 is connected to the bottom chamber 21. A damping through hole 251 is provided on the partition 25 to connect the bottom chamber 21 and the storage chamber 24. The storage chamber 24 includes upper and lower storage compartments 241. A partition 25 is provided between each storage compartment 241. A damping through hole 251 is provided on the partition 25.

[0034] A viscous fluid 22 is provided in the bottom chamber 21. A piston assembly 23 can slide up and down within the bottom chamber 21. The piston assembly 23 is connected to a counterweight assembly 4. After the tower body 1 sways and tilts, the connecting line 3 lifts the counterweight assembly 4 and the piston assembly 23, pushing the viscous fluid 22 through the damping through-hole 251. Due to the damping effect generated by the throttling of the small holes in the damping through-hole 251, the viscous fluid 22 can pass through the damping through-hole 251, but a reaction force is generated to limit the swaying of the tower body 1. In practical applications, different damping effects are produced by setting small holes of different sizes and numbers in each layer of partition 25. This method has a long service life; the viscous fluid 22 can produce a damping effect as long as it exists in the bottom chamber 21, and it will not interfere with or cause friction to other components. It can be repeatedly utilized. Without considering the fatigue limit of the viscous fluid 22 itself, the reservoir 24 includes multiple reservoir compartments 241, with partitions 25 between them. Damping through holes 251 are also provided on the partitions 25, so that different degrees of damping force can be generated in segments. After the reservoir compartment 241 near the bottom chamber 21 is filled with viscous fluid 22, when the piston continues to move, the viscous fluid 22 needs to pass through the damping through holes 251 between the bottom chamber 21 and the reservoir compartment 241, as well as the damping through holes 251 between the two reservoir compartments 241, thereby increasing the damping. Similarly, in practical applications, different numbers and volumes of reservoir compartments 241 can be set to obtain different degrees of increasing damping force, and the change nodes of the damping force can be controlled.

[0035] like Figure 2 As shown, a pressurization assembly 26 is connected to the storage chamber 24. In this embodiment, the pressurization assembly 26 is an air compressor. The piston assembly 23 includes a sensor assembly 27, which includes a limit sensor 271. An elastic element 272 is connected to the limit sensor 271. The end of the elastic element 272 away from the limit sensor 271 is connected to the piston assembly 23. When the limit sensor 271 touches the partition, the air compressor starts to work and inputs compressed air.

[0036] Since the damping force generated by the viscous fluid 22 comes entirely from the stroke of the piston assembly 23, when the piston assembly 23 reaches its maximum stroke, the sensor assembly 27, including a limit sensor 271 and connected to an elastic element 272, will trigger the pressurization assembly 26 after the limit sensor 271 contacts the partition 25. However, there is still a certain amount of viscous fluid 22 in the bottom chamber 21. At this time, compressed air is injected into the storage chamber 24 through the pressurization assembly 26, thereby increasing the resistance in the storage chamber 24 again, thus resisting the large-scale shaking of the tower body 1. When not in operation, it can transport the compressed air in the storage chamber 24, and when in operation, it can transport compressed air. The compressed air controls the flow of the viscous fluid 22. As the piston assembly 23 is raised again, it will squeeze the elastic element 272, while the limit sensor 271 remains in contact with the partition 25. This ensures that the pressurized air can be delivered continuously. After the large-scale shaking of the tower body 1 disappears, the piston assembly 23, which has exceeded its limit, ensures that the limit sensor 271 remains in contact with the partition 25 until the piston assembly 23 returns to its stroke. This allows the pressurizing assembly 26 to continuously inject compressed air, helping the piston assembly 23 to quickly return to its stroke and preventing the piston assembly 23 from failing to quickly reach the working state.

[0037] like Figure 2 , 5 As shown, a one-way flow member 28 is provided on the partition 25. The one-way flow member 28 includes a return hole 281 provided on the partition 25. A one-way valve cover plate 282 is hinged to the side of the partition 25 near the bottom compartment 21. When the piston assembly 23 is raised, the viscous fluid 22 can push the one-way valve cover plate 282 to abut against the partition 25. When the piston assembly 23 is lowered, the one-way valve cover plate 282 can disengage from the partition 25 by its own weight and the reverse push of the viscous fluid 22.

[0038] The one-way flow element 28 provided on the partition 25 can accelerate the return speed of the viscous fluid 22. Due to the one-way flow, when the piston assembly 23 is lifted, the viscous fluid 22 can only flow through the damping through hole 251, ensuring the stability of the damping force. When the one-way valve cover plate 282 provided on the side of the return hole 281 near the bottom compartment 21 is subjected to the upward flow of the viscous fluid 22, it will be pressurized by the viscous fluid 22 and abut against the partition 25, preventing the viscous fluid 22 from passing through the return hole 281. When the piston assembly 23 retracts, the flow direction of the viscous fluid 22 is reversed. After flowing through the return hole 281, it pushes open the one-way valve cover plate 282, accelerating the return efficiency of the viscous fluid 22.

[0039] like Figure 4As shown, the counterweight assembly 4 includes a rigid connecting rod 41, which is connected to the piston rod 231 in the piston assembly 23. Through the connection between the rigid connecting rod 41 and the piston assembly 23, the counterweight assembly 4 can directly apply pressure to the piston assembly 23, thus ensuring that the counterweight assembly 4 provides a restoring force during the retraction of the piston assembly 23. The rigid connecting rod 41 and the piston assembly 23 are hinged, allowing for some deformation and easy installation. Furthermore, it effectively transmits the restoring force to the piston assembly 23 when the counterweight assembly 4 wobbles or shifts.

[0040] In this embodiment, the assembly and operation of the self-adjusting damping prestressed vibration reduction system of the tower structure are as follows: In this embodiment, the tower body 1 is a hollow structure, including a tower top 11 and a tower base 12. A self-adjusting damper 2 is connected to the tower base 12, and a counterweight assembly 4 is connected above the self-adjusting damper 2. The self-adjusting damper 2 is connected to the counterweight assembly 4 through a rigid connecting rod 41. The other end of the counterweight assembly 4 is connected to a connecting line 3, which is connected to the tower top 11. During operation, when the wind force is small, the tower body 1 deforms little, mainly relying on the free stiffness of the tower body 1 and the prestress generated by the counterweight assembly 4 to resist the wind load. When the wind force increases further, the displacement of the tower top 11 increases, driving the connecting line 3 to lift the counterweight assembly 4, which in turn lifts the piston assembly 23 through the piston connecting rod. The viscous fluid 22 flows from the bottom chamber 21. The fluid enters the first storage compartment 241 above through the damping through-hole 251, generating damping to limit the displacement of the tower top 11. If the displacement increases further, the piston assembly 23 continues to rise, and the viscous fluid 22 flows into the second storage compartment 241, generating even greater damping, and so on. By setting small holes of different sizes and numbers in each partition 25, different damping effects are generated. When the displacement is too large and exceeds the stroke range of the piston assembly 23, the limit sensor 271 contacts the partition 25, and the air compressor is started to inject compressed air into the storage compartment 24, increasing the damping and further increasing the restriction on the tower body 1. After the swing of the tower body 1 is eliminated, the counterweight assembly 4 provides restoring force and drives the piston assembly 23 to move down. Each one-way valve cover plate 282 opens, the viscous fluid 22 flows back, and after the limit sensor 271 separates from the partition 25, the air compressor is turned off.

[0041] Example 2:

[0042] like Figure 6 , 7 As shown, unlike Embodiment 1, in this embodiment, multiple limiters 5 are connected to the inner wall of the tower body 1. Each limiter 5 is provided with a centroidal through hole 51. The connecting line 3 passes through each centroidal through hole 51 and connects to the counterweight component 4. The interval between each limiter 5 decreases from the tower base 12 along the tower top 11.

[0043] The centroidal perforation 51 is located on the centroidal line of the tower body 1. The connecting line 3 passes through the centroidal perforation 51 of the limiter 5. When the tower body 1 sways and tilts, the connecting line 3 at the centroidal perforation 51 remains aligned with the centroidal line of the tower body 1, making the lifting effect of the connecting line 3 on the counterweight assembly 4 and the piston assembly 23 more obvious. If there is no constraint from the limiter 5, the connecting line 3 will deviate and cannot provide effective tension, thus causing the device to fail. Since the deformation of the top area of ​​the tower body 1 is greater than that of the bottom area of ​​the tower body 1, the interval between the limiters 5 near the top of the tower 11 is reduced. When the tower body 1 sways, the connecting line 3 can be aligned with the centroidal line of the tower body 1 as much as possible, thus ensuring that the stretching effect of the connecting line 3 is obvious when swaying.
