Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a signal tower. Background Technology

[0002] A signal tower is a wireless signal transmitting device used to support signal transmission; it is also a public radio station. A radio station refers to a radio transceiver station that transmits and receives information between a mobile phone terminal and a communication switching center within a defined radio coverage area. When maintaining signal towers, operators typically need to climb manually or use lifting equipment to reach the tower's height. However, due to the tower's relatively tall structure and small cross-section, its stability is poor and its seismic resistance is insufficient when subjected to lateral loads (such as wind loads), resulting in high safety risks for operators during maintenance work. Summary of the Invention

[0003] To solve at least one of the above-mentioned technical problems, the present invention provides a signal tower that can improve the seismic resistance and stability of the signal tower and reduce the safety risks to operators during maintenance work.

The two ends of the reinforcing connector are respectively connected to the reinforcing ring and the base, and the reinforcing connector has an inclination angle relative to the height direction of the tower body.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention provides a signal tower. A lifting device and a support plate are installed on the side of the base away from the ground. The lifting device and support plate extend along the height of the tower and are connected to the tower body. A shock-absorbing component is fitted around the outer periphery of the tower body and connected to the support plate. The shock-absorbing component is used to dampen the tower body when it is subjected to a lateral load in a single direction, or to simultaneously reduce the force exerted on the tower body by lateral loads in different directions when it is subjected to lateral loads in multiple directions. Thus, the shock-absorbing component, fitted around the outer periphery of the tower body, provides support and dissipates vibration energy when the tower body is subjected to lateral loads in different directions. When the tower body is subjected to a single lateral load in any direction, the shock-absorbing component can support the tower body and reduce or dissipate the force exerted by the lateral load, thereby damping the tower body. When the tower body is subjected to lateral loads in multiple directions simultaneously, the shock-absorbing component can simultaneously reduce or dissipate the force exerted on the tower body by lateral loads in different directions, thereby achieving uniform shock absorption of the tower body. It is evident that the signal tower provided by this invention can not only reduce vibration when the tower body is subjected to a single lateral load in any direction, but also uniformly reduce vibration when the tower body is subjected to lateral loads in multiple directions simultaneously. This effectively improves the seismic resistance and stability of the signal tower and reduces the safety risks for operators during maintenance.

[0024] Furthermore, by setting up a lifting device that extends along the height direction of the tower, and the lifting device being used to move along the height direction of the tower, the signal tower has the function of manual or electric control of lifting. This facilitates the transportation of operators to high-altitude work positions, so that operators do not need to manually climb to the top of the tower when performing maintenance work on the signal tower, thereby reducing the safety risks associated with manual climbing and making the maintenance work safer for operators.

[0043] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0044] Please refer to the following: Figures 1 to 5 This invention provides a signal tower 1, including a base 10, a tower body 20, a shock-absorbing component 30, a lifting device 40, and a support plate 50. The tower body 20 is installed on the side of the base 10 away from the ground. The lifting device 40 and the support plate 50 are both disposed on the side of the base 10 away from the ground and are spaced apart. The lifting device 40 and the support plate 50 are respectively along the height direction of the tower body 20 (i.e., Figure 1 and Figure 2 The lifting device 40 extends and connects to the tower body 20 in the z direction. The lifting device 40 is used to move along the height direction of the tower body 20. The shock absorption component 30 is sleeved on the outer periphery of the tower body 20 and connected to the support plate 50. The shock absorption component 30 is used to dampen the tower body 20 when it is subjected to lateral load.

[0045] The signal tower 1 provided in this embodiment of the invention has a lifting device 40 and a support plate 50 spaced apart on the side of the base 10 away from the ground. The lifting device 40 and the support plate 50 extend along the height direction of the tower body 20 and are connected to the tower body 20. The shock absorption component 30 is sleeved on the outer periphery of the tower body 20 and connected to the support plate 50. The shock absorption component 30 is used to dampen the tower body 20 when it is subjected to a lateral load in a single direction, or to reduce the force of the lateral loads in different directions on the tower body 20 when it is subjected to lateral loads in multiple directions. In this way, the vibration damping component 30 is fitted around the outer periphery of the tower body 20. This means that the tower body 20 can be supported and have its vibration energy dissipated by the vibration damping component 30 when subjected to lateral loads in different directions. When the tower body 20 is subjected to a single lateral load in any direction, the vibration damping component 30 can reduce or dissipate the force exerted on the tower body 20 by the lateral load, thus damping the tower body 20. When the tower body 20 is subjected to lateral loads in multiple directions simultaneously, the vibration damping component 30 can simultaneously reduce or dissipate the force exerted on the tower body 20 by lateral loads in different directions, thereby achieving uniform vibration damping of the tower body 20. Therefore, the signal tower 1 provided by this invention can not only dampen the tower body 20 when subjected to a single lateral load in any direction, but also provide uniform vibration damping when the tower body 20 is subjected to lateral loads in multiple directions simultaneously. This effectively improves the seismic resistance and stability of the signal tower 1 and reduces the safety risks for operators during maintenance work.

[0046] Furthermore, by providing a lifting device 40 that extends along the height direction of the tower body 20, and by moving the lifting device 40 along the height direction of the tower body 20, the signal tower 1 is equipped with a manual or electric lifting function. This facilitates the transport of operators to high-altitude work positions, eliminating the need for operators to manually climb to the height of the tower body 20 when performing maintenance work on the signal tower 1. This reduces the safety risks associated with manual climbing and makes the maintenance work safer for operators.

[0047] Optionally, considering that when the shock-absorbing component 30 is spaced apart from the tower body 20, the tower body 20 needs to undergo a certain degree of swaying displacement to contact the shock-absorbing component 30 and thus obtain shock absorption protection, which affects the stability and reliability of the signal tower 1, the shock-absorbing component 30 is abutted against the outer periphery of the tower body 20 so that the shock-absorbing component 30 is always supported by the tower body 20.

[0048] In this way, since the damping component 30 always maintains contact with the tower body 20, when the tower body 20 sways or tends to sway under the action of lateral load, the damping component 30 can respond to the displacement of the tower body 20 in a timely manner and support the tower body 20. At the same time, it consumes the energy of the vibration caused by the lateral load on the tower body 20, so as to offset at least part of the effect of the lateral load on the tower body 20, thereby reducing the movement tendency of the tower body 20 and effectively avoiding large swaying displacement of the tower body 20, thus improving the stability and reliability of the signal tower 1. In this way, when the tower body 20 is subjected to a large lateral load, the damping component 30 can offset at least part of the effect of the lateral load on the tower body 20 in a timely manner, so as to avoid the situation where the tower body 20 sways violently under the instantaneous impact of the lateral load, causing damage to the structural reliability of the signal tower 1. When the tower body 20 is subjected to a small lateral load, even if the swaying of the tower body 20 is slight, the damping component 30 can also dampen the tower body 20 in a timely manner, avoiding irreversible damage to the structure of the signal tower 1 caused by long-term slight swaying, thereby ensuring the structural reliability of the signal tower 1.

[0049] Understandably, in some other embodiments, the shock-absorbing component 30 may also be spaced apart from the tower body 20 with a certain gap or a small gap.

[0050] Please combine Figure 1 and Figure 6 In some embodiments, the vibration damping component 30 includes a fixed structure 301 and a damping plate 302. The fixed structure 301 is connected to the support plate 50, and the damping plate 302 is disposed between the fixed structure 301 and the tower body 20 and abuts against the outer periphery of the tower body 20. The damping plate 302 is used to absorb the vibration of the tower body 20.

[0051] In this way, when the tower body 20 is subjected to lateral load, the vibration of the tower body 20 can be absorbed by the damping plate 302, so as to reduce the impact force of the tower body 20 relative to the damping component 30, reduce the swaying displacement of the tower body 20, and thus improve the stability of the signal tower 1.

[0052] In some embodiments, considering the large height of the tower body 20, when the shock absorber component 30 is integrally formed or prefabricated and assembled in the factory, the shock absorber component 30 needs to be sleeved on the outer periphery of the tower body 20 from the end of the tower body 20 and moved along the height direction of the tower body 20 to the target setting position. The installation steps are relatively complicated and difficult to operate. Based on this, the shock absorber component 30 is a split structure so that the shock absorber component 30 can be processed and assembled into an integral structure on the construction site, which is conducive to the installation of the shock absorber component 30.

[0053] Optionally, the fixing structure 301 includes two first fixing plates 3011 and two second fixing plates 3012. The two first fixing plates 3011 are arranged opposite to each other, with one side of the first fixing plate 3011 facing away from the tower body 20 connected to the support plate 50. The two second fixing plates 3012 are arranged opposite to each other, and each second fixing plate 3012 is located at one end of a first fixing plate 3011, with each end of the second fixing plate 3012 connected to one of the two first fixing plates 3011. The direction in which the two first fixing plates 3011 face each other is defined as the first direction (i.e., Figure 2 , Figure 3 and Figure 6 The x-direction in the middle), the direction in which the two second fixed plates 3012 are opposite each other is the second direction (i.e., Figure 6 and Figure 7 The first fixing plate 3011 and the second fixing plate 3012 are arranged in a rectangular structure, with the first fixing plate 3011 and the second fixing plate 3012 perpendicular to the second fixing plate 3012. Thus, the fixing structure 301, formed by four plate components, creates a rectangular ring structure for the damping assembly 30. This allows it to dampen the tower 20 when subjected to lateral loads from all sides. Furthermore, when the tower 20 is subjected to lateral loads from multiple directions, adjacent damping plates can simultaneously reduce or dissipate the force exerted on the tower 20 by lateral loads from different directions, achieving uniform damping of the tower 20. In addition, the damping assembly 30 has a simple structure, is easy to assemble, and facilitates its installation on the outer periphery of the tower 20, simplifying the installation process.

[0054] Understandably, in other embodiments, the shape of the shock-absorbing component 30 may also be annular, arc-shaped, or polygonal, etc., which can be set according to actual needs and is not limited here.

[0055] Optionally, the first fixing plate 3011 and the second fixing plate 3012 are connected by welding, which simplifies and facilitates the assembly of the vibration damping component 30. Furthermore, the assembly of the first fixing plate 3011 and the second fixing plate 3012 is not limited to pre-shipment assembly or on-site assembly. Since welding involves fewer parts, it is more adaptable to on-site assembly conditions. During the installation of the vibration damping component 30, the target installation position on the tower body 20 can be first located. The first fixing plate 3011 and the second fixing plate 3012 are then arranged around the outer perimeter of the tower body 20 and welded together to fix the vibration damping component 30 to the signal tower 1.

[0056] Understandably, in other embodiments, the connection between the first fixing plate 3011 and the second fixing plate 3012 can also be any one of threaded connection, snap-fit ​​connection or adhesive connection. There are no restrictions here, and the specific connection can be set according to actual needs.

[0057] In some embodiments, the damping plate 302 includes a first damping plate 3021, which is used to absorb the vibration of the tower body 20, and the first damping plate 3021 is movably connected to the first fixing plate 3011 of the fixing structure 301.

[0058] In this way, when the lateral load on the tower body 20 is too large, the first damping plate 3021 absorbs part of the vibration energy of the tower body 20 by relying on its own damping material performance, while the unabsorbed vibration energy drives the tower body 20 to sway, causing the first damping plate 3021 that is in contact with the tower body 20 to move away from the tower body 20. This can prevent the tower body 20 from impacting and colliding with the damping component 30 due to swaying, thus avoiding structural damage to the signal tower 1.

[0059] Optionally, the vibration damping assembly 30 includes a first damping rod 303. Along a first direction, one end of the first damping rod 303 is connected to the first damping plate 3021, and the other end is connected to the first fixing plate 3011 of the fixing structure 301, so that the first damping plate 3021 and the first fixing plate 3011 are movably connected. In this way, by utilizing the damping characteristics of the first damping rod 303, the first damping rod 303 can consume energy and attenuate vibrations. This allows the vibration damping assembly 30 to not only absorb the vibration energy of the tower body 20 through the material properties of the first damping plate 3021 itself, but also reduce and buffer the vibration energy of the tower body 20 through the damping characteristics of the first damping rod 303, thereby further damping the tower body 20. This achieves multiple vibration damping of the tower body 20 by the vibration damping assembly 30, thereby improving the vibration damping effect of the vibration damping assembly 30, further improving the seismic resistance of the signal tower 1, and thus improving the stability and reliability of the signal tower 1.

[0060] Optionally, the damping assembly 30 further includes a first elastic element 305, which is sleeved on the outer periphery of the first damping rod 303 (see...). Figure 3 ).

[0061] In this way, by utilizing the stretchable deformation capability of the elastic element, the instantaneous impact force on the first damping plate 3021 can be buffered, and the first damping plate 3021 can be driven to move to a state that maintains contact with the tower body 20. That is to say, by setting the first elastic element 305, the first damping plate 3021, after being damped by the first damping rod 303, can return to the state of contact with the tower body 20 under the drive of the elastic force of the first elastic element 305. Furthermore, the vibration energy is consumed during the reciprocating motion of the elastic element and the damping rod, thereby further realizing the damping effect.

[0062] Based on this, when the tower body 20 sways under the action of a lateral load, the vibration energy of the tower body 20 is first absorbed by the first damping plate 3021. The remaining unabsorbed vibration energy further drives the tower body 20 to exert a force relative to the first damping plate 3021, thereby causing the first damping plate 3021 to move. At this time, the first damping plate 3021 moves along the first direction away from the tower body 20, compressing the first elastic element 305 and the first damping rod 303, causing the first elastic element 305 and the first damping rod 303 to undergo compression deformation respectively. During the deformation process, the first damping rod 303 absorbs vibration energy, and the first elastic element 305, under the action of elastic force, drives the first damping plate 3021 to reciprocate along the first direction, thereby consuming the vibration energy and impact force received by the first damping plate 3021, thus achieving multiple vibration damping of the tower body 20 along the first direction.

[0063] Understandably, in some other embodiments, the first elastic element 305 may also be spaced apart from the first damping rod 303. The specific arrangement can be determined according to actual needs and is not limited here.

[0064] Please refer to it again. Figure 2 and Figure 3 In some embodiments, the shock-absorbing assembly 30 further includes a first sliding plate 307, a fixing rod 308, and a transmission assembly 309. The first fixing plate 3011 of the fixing structure 301 is provided with a first buffer groove 3011a and a first mounting hole. The first buffer groove 3011a is disposed inside the first fixing plate 3011 of the fixing structure 301, and the first mounting hole is disposed on the side of the first fixing plate 3011 facing the tower body 20 and communicates with the first buffer groove 3011a. The first sliding plate 307, the transmission assembly 308, and the first mounting rod 309 are also included. 09. The first damping rod 303 and the first elastic element 305 are disposed in the first buffer groove 3011a. The fixing rod 308 passes through the first mounting hole, and the two ends of the fixing rod 308 are respectively connected to the first sliding plate 307 and the first damping plate 3021. The transmission assembly 309 is connected to the side of the first sliding plate 307 away from the first damping plate 3021. The two ends of the first damping rod 303 and the first elastic element 305 are respectively connected to the inner wall surface of the transmission assembly 309 and the first buffer groove 3011a.

[0065] Considering that the working environment of signal tower 1 is generally at a high altitude or in a relatively open environment, signal tower 1 has a lot of contact with dust, impurities or liquids in the air. Based on this, a first buffer groove 3011a is set in the first fixed plate 3011, and the first sliding plate 307, transmission component 309, first damping rod 303 and first elastic element 305 are all set in the first buffer groove 3011a of the first fixed plate 3011. This is to protect the structure of the shock absorption component 30, reduce the contact and adhesion of air impurities, liquids and other objects with the first sliding plate 307, first damping rod 303 and first elastic element 305, ensure the reliability of the movement of the first sliding plate 307, first damping rod 303 and first elastic element 305, and avoid situations where the movement is restricted or jammed due to the adhesion of dust or impurities on the structural surface of the shock absorption component 30, or where the structure is rusted or damaged due to chemical reaction between the liquid and the structure of the shock absorption component 30, resulting in the inability to achieve normal movement. Simultaneously, the fixing rod 308 passes through the first mounting hole to connect the first sliding plate 307 inside the first buffer groove 3011a and the first damping plate 3021 located outside the first buffer groove 3011a. This ensures that the first damping plate 3021 is connected to the first sliding plate 307 while completely or largely sealing the first mounting hole, reducing the amount of dust, impurities, or liquid entering the first buffer groove 3011a, thereby improving the sealing performance of the first buffer groove 3011a and enhancing the structural reliability of the damping assembly 30. Furthermore, the first sliding plate 307, connected to the first damping plate 3021 through the first mounting hole via the fixing rod 308, can limit the movement of the first sliding plate 307, preventing it from detaching from the first buffer groove 3011a. This restricts the range of movement of the tower body 20 and the first damping plate 3021, thereby limiting the vibration displacement amplitude of the tower body 20 and improving the structural stability and reliability of the signal tower 1.

[0066] Optionally, there can be multiple fixing rods 308, which are evenly spaced and have the same length. This makes the connection between the second damping plate 3022 and the second sliding plate 312 stable and reliable, thereby improving the structural stability of the transmission assembly 309 and preventing structural damage to the damping assembly 30 caused by the swaying displacement of the tower body 20.

[0067] Optionally, the transmission assembly 309 includes a transmission base 3091, a first rotating part 3092, a second rotating part 3093, and a fixed block 3094. The two ends of the transmission base 3091 along the first direction are respectively connected to the first sliding plate 307 and the first damping rod 303. The first rotating part 3092 is rotatably connected to the transmission base 3091, and the second rotating part 3093 is rotatably connected to the fixed block 3094. The first rotating part 3092 is movably connected to the second rotating part 3093.

[0068] In this way, by setting the transmission component 309, when the first damping plate 3021 receives a force (i.e., vibration energy and impact force) along the first direction, the force is transmitted to the first sliding plate 307 through the fixed rod 308. The first sliding plate 307 drives the transmission seat 3091 to move relative to the first buffer groove 3011a. At this time, the transmission seat 3091 and the inner wall surface of the first buffer groove 3011a have multiple connection points, which helps to disperse and reduce the force received by the first damping plate 3021 through multiple connection points, thereby improving the damping effect of the damping component 30 and improving the damping capability of the signal tower 1. Meanwhile, by setting the first rotating part 3092 and the second rotating part 3093, when the transmission seat 3091 moves relative to the inner wall surface of the first buffer groove 3011a, the first rotating part 3092 and the second rotating part 3093 can adapt to the change in distance between the transmission seat 3091 and the fixed block 3094, so as to ensure the structural reliability of the transmission assembly 309 and to disperse and reduce the force on the first damping plate 3021.

[0069] Optionally, the first rotating part 3092 is slidably connected to the second rotating part 3093. Specifically, the end of the first rotating part 3092 away from the transmission seat 3091 is provided with a slider, and the end of the second rotating part 3093 away from the fixed block 3094 is provided with a groove. The slider is slidably connected to the groove, and a spring is provided in the groove. The two ends of the spring are respectively connected to the inner wall of the groove and the first rotating part 3092, so that the first rotating part 3092 is movably connected to the second rotating part 3093. This allows part of the force received by the transmission seat 3091 to be reduced by the first elastic element 305 and the first damping rod 303, and the other part to be dispersed and buffered by the first rotating part 3092, the spring, and the second rotating part 3093, so as to achieve the effect of multi-point shock absorption.

[0070] Optionally, there can be multiple first rotating parts 3092, second rotating parts 3093, and fixing blocks 3094. Multiple first rotating parts 3092, second rotating parts 3093, and fixing blocks 3094 correspond one-to-one. Two fixing blocks 3094 are respectively disposed on both sides of the transmission seat 3091. The two sides of the transmission seat 3091 are respectively provided with a first protrusion and a second protrusion along the length direction of the first sliding plate 307, and the protrusion directions of the first protrusion and the second protrusion are opposite. Two first rotating parts 3092 are rotatably connected to the first protrusion and the second protrusion, thereby making the structure of the transmission assembly 309 more stable and reliable.

[0071] Optionally, the rotational connection between the first rotating part 3092 and the transmission base 3091 can be a hole-shaft connection, and the connection between the second rotating part 3093 and the fixed block 3094 can also be a hole-shaft connection. Specifically, one of the first rotating part 3092 and the transmission base 3091 is provided with a rotating shaft, and the other is provided with a shaft hole. The rotating shaft is rotatably connected to the shaft hole, so that the first rotating part 3092 and the transmission base 3091 are connected in a transmission connection. Similarly, one of the second rotating part 3093 and the fixed block 3094 is provided with a rotating shaft, and the other is provided with a shaft hole. The rotating shaft is rotatably connected to the shaft hole, so that the second rotating part is connected in a transmission connection with the fixed block 3094.

[0072] Optionally, there can be multiple first damping rods 303 and first elastic elements 305. Each first damping rod 303 corresponds one-to-one with a first elastic element 305, and the multiple first damping rods 303 are evenly spaced and spaced apart. The lengths of the multiple first damping rods 303 are consistent, and both the multiple first damping rods 303 and the first elastic elements 305 are located between multiple first rotating parts 3092. This makes the structure of the transmission assembly 309 more stable. When the force on the first damping plate 3021 is transmitted through the fixed rod 308, When the first sliding plate 307 and the transmission seat 3091 transmit the force to the first damping rod 303 and the first elastic element 305, the multiple first damping rods 303 deform simultaneously. This avoids the situation where the force transmitted to the first damping rods 303 at different positions is inconsistent due to the inconsistent length of the first damping rods 303, which would cause the first sliding plate 307 to tilt and become unbalanced. This would affect the force transmission of the first damping plate 3021 and result in uneven damping of the tower body 20 by the damping assembly 30 in all directions.

[0073] In some embodiments, considering that the connection area between the transmission seat 3091 and the first sliding plate 307 affects the transmission of the force from the tower body 20 to the first damping plate 3021, when the connection area between the transmission seat 3091 and the first sliding plate 307 is small, when the direction of the force applied by the tower body 20 to the first damping plate 3021 has an angle of inclination relative to the first direction, the first damping plate 3021 moves toward the first sliding plate 307 along the direction of the force, and the first sliding plate 307 is driven to move along the direction of the force by the fixing rod 308. Since the first sliding plate 307 is located in the first buffer groove 3011a, the movement of the first sliding plate 307 is restricted by the first buffer groove 3011a. When one end of the first sliding plate 307 moves away from the tower body 20, the other end of the first sliding plate 307 is at risk of interference with the inner wall of the first buffer groove 3011a, causing the first sliding plate 307 to be unable to continue moving, thereby restricting the transmission of the force and failing to achieve the maximum damping effect. Based on this, the shock absorption assembly 30 also includes two telescopic rods 310 and a third elastic element 311 sleeved on the outer periphery of the telescopic rods 310. The telescopic rods 310 and the third elastic element 311 are both disposed in the first buffer groove 3011a and located on the side of the first sliding plate 307 away from the first shock absorption plate 3021. The two telescopic rods 310 are respectively located at both ends of the first sliding plate 307. The transmission assembly 309 is located between the two telescopic rods 310. The two ends of the telescopic rods 310 are respectively connected to the inner wall surfaces of the first sliding plate 307 and the first buffer groove 3011a.

[0074] In this way, the first sliding plate 307 is supported by multiple points of connection with the inner wall of the first buffer groove 3011a, which can improve the structural stability of the damping assembly 30. At the same time, the two telescopic rods 310 are located at both ends of the first sliding plate 307 and connected to it, which can restrict the movement direction of the first sliding plate 307, so that the first sliding plate 307 always moves in the first direction when subjected to force, thereby improving the reliability of the structure and facilitating the damping of the tower body 20 by the damping assembly 30. In addition, the addition of the telescopic rods 310 and the third elastic element 311 can also buffer and disperse the force transmitted from the tower body 20 to the first sliding plate 307, thereby achieving the effect of damping.

[0075] In other words, when the tower body 20 is subjected to a lateral load and sways, the vibration energy is first absorbed and buffered by the material of the first damping plate 3021 itself, so as to reduce the impact force of the tower body 20 relative to the damping component 30 and reduce the swaying displacement of the tower body 20. Secondly, when the first damping plate 3021 transmits the force (vibration and impact force) of the tower body 20 to the first sliding plate 307 through the fixed rod 308, it can absorb energy and attenuate vibration through the first damping rod 303 and the first elastic element 305, disperse and reduce the force through the transmission component 309, and buffer and disperse the force through the telescopic rod 310 and the third elastic element 311. Thus, the damping component 30 can achieve multiple damping effects on the tower body 20, thereby improving the seismic resistance of the signal tower 1.

[0076] Understandably, in some other embodiments, the third elastic element 311 may also be spaced apart from the telescopic rod 310. The specific arrangement can be determined according to actual needs and is not limited here.

[0077] Please refer to it again. Figure 6 and Figure 7 In some embodiments, the damping plate 302 further includes a second damping plate 3022, which is used to absorb the vibration of the tower body 20, and the second damping plate 3022 is movably connected to the second fixing plate 3012 of the fixing structure 301.

[0078] In this way, when the lateral load on the tower body 20 is too large, the second damping plate 3022 absorbs part of the vibration energy of the tower body 20 by relying on its own damping material performance, while the unabsorbed vibration energy drives the tower body 20 to sway, causing the second damping plate 3022 that is in contact with the tower body 20 to move away from the tower body 20. This can prevent the tower body 20 from impacting and colliding with the damping component 30 due to swaying, thus avoiding structural damage to the signal tower 1.

[0079] Optionally, the materials of the first damping plate 3021 and the second damping plate 3022 can be rubber, EVA (Ethylene-Vinyl Acetate Copolymer), ACF (Artificial Cartilage Foam), D3O material (expandable foam), or PU (polyurethane), etc. By utilizing the good elasticity and buffering capacity of the first damping plate 3021 and the second damping plate 3022, vibration can be effectively absorbed to reduce the impact force of the tower body 20 relative to the damping component 30, reduce the swaying displacement of the tower body 20, and thus improve the stability of the signal tower 1.

[0080] Optionally, the vibration damping component 30 includes a second damping rod 304. Along a second direction, one end of the second damping rod 304 is connected to the second damping plate 3022, and the other end is connected to the second fixing plate 3012 of the fixing structure 301, so that the second damping plate 3022 and the second fixing plate 3012 are movably connected along the second direction. In this way, utilizing the damping characteristics of the second damping rod 304, the second damping rod 304 can dissipate energy and attenuate vibrations. This allows the vibration damping component 30 to not only absorb the vibration energy of the tower body 20 through the material properties of the second damping plate 3022 itself, but also to reduce and buffer the vibration energy of the tower body 20 through the damping characteristics of the second damping rod 304, further reducing the vibration of the tower body 20. This achieves multiple vibration damping effects of the vibration damping component 30 on the tower body 20, thereby improving the vibration damping effect of the vibration damping component 30, further improving the seismic resistance of the signal tower 1, and ultimately improving the stability and reliability of the signal tower 1.

[0081] Furthermore, as mentioned above, by making the first damping plate 3021 movably connected to the first fixed plate 3011 along the first direction, and the second damping plate 3022 movably connected to the second fixed plate 3012 along the second direction, that is, the first damping plate 3021 and the first damping rod 303, as well as the second damping plate 3022 and the second damping rod 304, can be displaced in different directions respectively, which can further realize that the damping assembly 30 uniformly damps the tower body 20 subjected to lateral loads in multiple directions.

[0082] Optionally, the damping assembly 30 further includes a second elastic element 306, which is sleeved on the outer periphery of the second damping rod 304 (see...). Figure 7 ).

[0083] In this way, by utilizing the stretchable deformation capability of the elastic element, the instantaneous impact force on the second damping plate 3022 can be buffered, and the second damping plate 3022 can be driven to move to maintain contact with the tower body 20. That is to say, by setting the second elastic element 306, the second damping plate 3022, after being damped by the second damping rod 304, can return to the state of contact with the tower body 20 under the drive of the elastic force of the second elastic element 306. Furthermore, the vibration energy is consumed during the reciprocating motion of the elastic element and the damping rod, thereby further realizing the damping effect.

[0084] Based on this, when the tower body 20 sways under the action of lateral load, the vibration energy of the tower body 20 is first absorbed by the first damping plate 3021 and the second damping plate 3022. The remaining unabsorbed vibration energy further drives the tower body 20 to exert a force relative to the first damping plate 3021 and the second damping plate 3022, thereby causing the first damping plate 3021 and the second damping plate 3022 to move. At this time, the second damping plate 3022 moves in the second direction away from the tower body 20, thereby compressing the second elastic element 306 and the second damping rod 304, causing the second elastic element 306 and the second damping rod 304 to undergo compression deformation respectively. The second damping rod 304 absorbs vibration energy during the deformation process, and the second elastic element 306 drives the second damping plate 3022 to reciprocate in the second direction under the action of elastic force, thereby consuming the vibration energy and impact force received by the second damping plate 3022, thus achieving multiple vibration reduction in the second direction.

[0085] Understandably, in some other embodiments, the second elastic element 306 may also be spaced apart from the second damping rod 304, and the specific arrangement can be determined according to actual needs, without limitation here.

[0086] In some embodiments, the damping assembly 30 further includes a second sliding plate 312 and a connecting rod 313. The second fixing plate 3012 of the fixing structure 301 is provided with a second buffer groove 3012a and a second mounting hole. The second buffer groove 3012a is disposed inside the second fixing plate 3012. The second mounting hole is disposed on the side of the second fixing plate 3012 facing the tower body 20 and communicates with the second buffer groove 3012a. The second sliding plate 312, the second damping rod 304 and the second elastic member 306 are all disposed in the second buffer groove 3012a. The connecting rod 313 passes through the second mounting hole, and the two ends of the connecting rod 313 are respectively connected to the second sliding plate 312 and the second damping plate 3022. The two ends of the second damping rod 304 and the second elastic member 306 are respectively connected to the side of the second sliding plate 312 away from the second damping plate 3022 and the inner wall surface of the second buffer groove 3012a.

[0087] In this way, the second sliding plate 312, the second damping rod 304, and the second elastic element 306 are all disposed in the second buffer groove 3012a of the second fixed plate 3012 to protect the structure of the shock absorber assembly 30 and reduce the contact and adhesion of air impurities, liquids, and other objects with the second sliding plate 312, the second damping rod 304, and the second elastic element 306. This ensures the reliability of the movement of the second sliding plate 312, the second damping rod 304, and the second elastic element 306, and avoids situations where the movement is restricted or jammed due to the adhesion of dust or impurities on the structural surface of the shock absorber assembly 30, or where the structure rusts or is damaged due to a chemical reaction between the liquid and the structure of the shock absorber assembly 30, resulting in the inability to achieve normal movement. Simultaneously, the connecting rod 313 passes through the second mounting hole to connect the second sliding plate 312 inside the second buffer groove 3012a and the second damping plate 3022 located outside the second buffer groove 3012a. This ensures that the second damping plate 3022 is connected to the second sliding plate 312 while completely or largely sealing the second mounting hole, reducing the amount of dust, impurities, or liquid entering the second buffer groove 3012a, thereby improving the sealing performance of the second buffer groove 3012a and enhancing the structural reliability of the damping assembly 30. Furthermore, the second sliding plate 312 is connected to the second damping plate 3022 through the second mounting hole via a fixing rod 308. This limits the movement of the second sliding plate 312, preventing it from detaching from the second buffer groove 3012a, thus restricting the range of movement of the tower body 20 and the second damping plate 3022, thereby limiting the vibration displacement amplitude of the tower body 20 and improving the structural stability and reliability of the signal tower 1.

[0088] Optionally, there can be multiple connecting rods 313, which are evenly spaced and have the same length. This makes the connection between the second damping plate 3022 and the second sliding plate 312 stable and reliable, thereby improving the structural stability of the transmission assembly 309 and preventing structural damage to the damping assembly 30 caused by the swaying displacement of the tower body 20.

[0089] Optionally, there can be multiple second damping rods 304 and second elastic elements 306. Each second damping rod 304 corresponds to a second elastic element 306, and the multiple second damping rods 304 are evenly and spaced apart. The lengths of the multiple second damping rods 304 are consistent, which makes the structure of the transmission assembly 309 more stable. When the force on the second damping plate 3022 is transmitted to the second damping rods 304 and the second elastic elements 306 through the connecting rod 313 and the second sliding plate 312, the multiple second damping rods 304 deform simultaneously. This can avoid the situation where the force transmitted to the second damping rods 304 at different positions is inconsistent due to the inconsistent lengths of the second damping rods 304, causing the second sliding plate 312 to tilt and become unbalanced, thereby affecting the force transmission of the second damping plate 3022 and causing the damping assembly 30 to damp the tower body 20 unevenly in all directions.

[0090] Optionally, the first elastic element 305, the second elastic element 306, and the third elastic element 311 can be leaf springs, coil springs, torsion bar springs, etc., and can be set according to actual needs. No restrictions are imposed here.

[0091] In some embodiments, considering that the shock-absorbing component 30 is connected to the support plate 50, the reliability of the connection between the support plate 50 and the base 10 will affect the shock absorption effect of the signal tower 1. At the same time, the lifting device 40 is used to drive the operator to move up and down along the height direction of the tower body 20. Therefore, the reliability of the connection between the lifting device 40 and the base 10 will affect the safety of the operator when performing maintenance work on the signal tower 1. As mentioned above, the first fixed plate 3011 has more layers of shock absorption design than the second fixed plate 3012, and its shock absorption effect is better. That is, the shock absorption effect of the shock-absorbing component 30 along the first direction is better than the shock absorption effect along the second direction. Based on this, the lifting device 40 is arranged opposite to the support plate 50, and one of its first fixed plates 3011 is located between the support plate 50 and the tower body 20 and connected to the support plate 50, the other first fixed plate 3011 is located between the lifting device 40 and the tower body 20, and the second fixed plate 3012 is located between the two first fixed plates 3011.

[0092] This reduces the impact of lateral loads on the lifting device 40 and the support plate 50, making the connection between the lifting device 40, the support plate 50 and the base 10 more reliable, thereby ensuring the safety performance of the lifting device 40 during use, and ensuring the reliability of the support plate 50 in providing support to the shock absorption component 30.

[0093] Optionally, the connection method between the first fixing plate 3011 and the support plate 50 can be any one of welding, threaded connection, snap-fit ​​connection or adhesive bonding. There is no restriction here, and the specific method can be set according to actual needs.

[0094] Optionally, along the height direction of the tower body 20, the width of the first fixing plate 3011 is greater than the width of the second fixing plate 3012, so that the first fixing plate 3011 and the support plate 50 have a larger connection area, thereby improving the connection reliability of the first fixing plate 3011 and the support plate 50, and further improving the connection reliability of the shock absorption assembly 30 and the support plate 50.

[0095] Please refer to it again. Figure 1 , Figure 2 and Figure 4 In some embodiments, the lifting device 40 includes a fixed ladder 41, a lifting plate 42, a traction rope 43, and a winding mechanism 44. The fixed ladder 41 is disposed on the side of the base 10 away from the ground and extends along the height direction of the tower body 20. One end of the fixed ladder 41 away from the base 10 is connected to the tower body 20. The lifting plate 42 is slidably connected to the fixed ladder 41 along the height direction of the tower body 20. The two ends of the traction rope 43 are respectively connected to the winding mechanism 44 and the lifting plate 42. The winding mechanism 44 is used to drive the traction rope 43 to wind or unwind around the outer periphery of the winding mechanism 44, so as to drive the lifting plate 42 to rise or fall along the height direction of the fixed ladder 41.

[0096] In this way, the lifting plate 42 is driven to move up and down along the height direction of the fixed ladder 41 by the winding mechanism 44 and the traction rope 43. This allows the operator to move up and down with the lifting plate 42 to reach the higher part of the signal tower 1 when maintenance is required. At the same time, by winding or unwinding the traction rope 43 around the outer periphery of the winding mechanism 44, the lifting plate 42 connected to the traction rope 43 rises or falls accordingly, making the lifting movement smoother and the structure of the lifting device 40 simpler.

[0097] Understandably, in this embodiment, in addition to controlling the electric lifting of the lifting plate 42 through the winding mechanism 44, the operator can also manually climb up the fixed ladder 41 to the maintenance work position to maintain the signal tower 1.

[0098] Optionally, the fixed ladder 41 includes two spaced vertical bars 411 and a plurality of horizontal bars 412. The vertical bars 411 extend along the length of the fixed ladder 41, and the two ends of the vertical bars 411 along their length are respectively connected to the base 10 and the tower body 20. The plurality of horizontal bars 412 are spaced along the length of the vertical bars 411, and the two ends of each horizontal bar 412 are respectively connected to the two vertical bars 411 to form a trapezoidal structure.

[0099] Please combine Figure 4 and Figure 5Optionally, the vertical rod 411 has a mounting groove 411a along its length, with the opening of the mounting groove 411a facing away from the tower body 20. The lifting device 40 also includes a lifting block 45 and a limiting rod 46 disposed in the mounting groove 411a. The limiting rod 46 extends along the length of the vertical rod 411, and the lifting block 45 is slidably connected to the limiting rod 46. The lifting block 45 is connected to the lifting plate 42 through the opening of the mounting groove 411a. The traction rope 43 extends at least partially into the vertical rod 411, and the end of the traction rope 43 away from the winding mechanism 44 is connected to the lifting plate 42. The winding mechanism 44 drives the traction rope 43 to wind or unwind around the outer periphery of the winding mechanism 44, so that the lifting block 45 moves up and down along the length of the limiting rod 46, thereby driving the lifting plate 42 to rise and fall.

[0100] In this way, by setting an installation groove 411a in the vertical bar 411 of the fixed ladder 41, not only can space be made reasonable, but the traction rope 43, the limiting rod 46, and the lifting block 45 can also be protected. This prevents the lifting device 40 from being damaged due to collisions between the traction rope 43 and the limiting rod 46, which are structures of length, and flying animals or aircraft at high altitudes. At the same time, by setting the limiting rod 46 in the installation groove 411a, the highest and lowest positions of the limiting block in the installation groove 411a can be limited, thereby limiting the displacement of the limiting block. This prevents the lifting block 45 from falling out of the installation groove 411a due to excessive lifting amplitude in the event of an abnormality in the winding mechanism 44 or due to tolerances in the winding length, which could cause the lifting plate 42 to fall out of the fixed ladder 41, thus improving the reliability of the lifting device 40.

[0101] In some embodiments, the vertical rod 411 is also provided with a bent lifting channel 411b, which connects the mounting groove 411a with the side of the vertical rod 411 facing the tower body 20. The traction rope 43 extends into the mounting groove 411a through the lifting channel 411b. The lifting device 40 also includes a rotating bearing and a guide wheel. The rotating bearing is located in the lifting channel 411b and at the bend of the lifting channel 411b. The guide wheel is located on the side of the vertical rod 411 facing the tower body 20. The end of the traction rope 43 away from the lifting block 45 is slidably connected to the rotating bearing and the guide wheel in sequence, and is wound and connected to the winding mechanism 44.

[0102] In this way, by setting a rotating bearing and a guide wheel, the traction rope 43 can smoothly pass through the curved channel to smoothly drive the lifting block 45 to complete the lifting movement, effectively avoiding the situation where the traction rope 43 is worn and broken or the movement of the traction rope 43 is stuck due to friction between the traction rope 43 and the inner wall of the mounting groove 411a or the lifting channel 411b.

[0103] Please combine Figure 4 and Figure 8Optionally, the winding mechanism 44 includes a first fixing box 441, a winding roller 442, and a drive assembly 443. The first fixing box 441 is disposed at one end of the vertical rod 411 away from the base 10. The interior of the first fixing box 441 is provided with a first mounting cavity and a third mounting hole 4411 and a fourth mounting hole communicating with the first mounting cavity. The third mounting hole 4411 extends along the length direction of the winding roller 442. The winding roller 442 is disposed in the first mounting cavity. One end of the traction rope 43 extends into the first fixing box 441 through the third mounting hole 4411 and is connected to the drive assembly 443. The outer periphery of the take-up roller 442 is provided with a first rotating shaft and a second rotating shaft at both ends of the take-up roller 442. The first rotating shaft is rotatably connected to the side wall of the first mounting cavity, and the second rotating shaft is used to extend out of the first fixed box 441 through the fourth mounting hole. The drive assembly 443 is connected to the rotating shaft and is used to drive the second rotating shaft to rotate, thereby driving the take-up roller 442 to rotate, so that the traction rope 43 is wound around the outer periphery of the take-up roller 442, thereby driving the lifting block 45 and the lifting plate 42 to move along the height direction of the tower body 20, thereby realizing the lifting control of the lifting plate 42.

[0104] By incorporating the take-up roller 442, guide wheel, and rotating bearing, the movement of the traction rope 43 becomes smoother, resulting in more stable and reliable movement of the lifting block 45 driven by the traction rope 43, thereby improving the reliability of the lifting movement of the lifting plate 42. Simultaneously, by providing the first mounting cavity, the winding movement of the take-up roller 442 occurs within the first fixed box 441, reducing the risk of contamination of the traction rope 43 and take-up roller 442 by airborne dust, impurities, or liquids. This also reduces damage to the traction rope 43 and take-up roller 442 from harsh environments such as rain and intense sunlight, thus protecting the traction rope 43 and take-up roller 442, improving the reliability of the winding movement, and ultimately enhancing the structural reliability of the winding mechanism 44.

[0105] Please combine Figure 9Optionally, the winding mechanism 44 further includes a second fixing box 444 and a third fixing box. The two sides of the second fixing box 444 are respectively connected to the first fixing box 441 and the third fixing box. The second fixing box 444 is provided with a second mounting cavity and a fifth mounting hole and a sixth mounting hole communicating with the second mounting cavity. The fifth mounting hole is correspondingly provided with a fourth mounting hole, and the second rotating shaft passes through the fourth mounting hole and the fifth mounting hole. The third fixing box is provided with a third mounting cavity and a seventh mounting hole communicating with the third mounting cavity. The sixth mounting hole and the seventh mounting hole are correspondingly provided. The drive assembly 443 includes a motor 4431, a first gear 4432, a second gear 4433, and a third rotating shaft. The motor 4431 is disposed in the third mounting cavity. The first gear 4432 and the second gear 4433 are disposed in the second mounting cavity and are meshed together. The second rotating shaft passes through the first gear 4432, and the third rotating shaft passes through the second gear 4433 and is rotatably connected to the second fixed box 444. The third rotating shaft passes through the sixth mounting hole and the seventh mounting hole in sequence, and is connected to the output shaft of the motor 4431.

[0106] In this way, the output shaft of motor 4431 drives the take-up roller 442 to rotate through the meshing of the first gear 4432 and the second gear 4433, which can reduce the range of variation in the output speed of motor 4431 and improve the smoothness and accuracy of the movement. At the same time, the drive assembly 443 is installed in the second fixed box 444 and the third fixed box, which can protect the drive assembly 443.

[0107] Understandably, considering that the housing of motor 4431 has a certain degree of sealing and can adapt to the outdoor environment, in some other embodiments, the winding mechanism 44 may also remove the third fixing box and place motor 4431 directly in the external environment.

[0108] As can be seen, the movement process of the lifting device 40 is as follows: the motor 4431 drives the third rotating shaft to drive the second gear 4433 to rotate. When the second gear 4433 rotates, it drives the first gear 4432 that meshes with it to rotate. The first gear 4432 drives the second rotating shaft to rotate, thereby driving the take-up roller 442 to rotate, so that the traction rope 43 can be wound or unwound around the outer circumference of the take-up roller 442. At this time, as the length of the traction rope 43 changes in the mounting groove 411a, the traction rope 43 drives the lifting block 45 to rise and fall along the height direction of the tower body 20, and then drives the lifting plate 42 to move up and down along the height direction of the tower body 20.

[0109] Optionally, the motor 4431 can be a servo motor 4431, a stepper motor 4431, or a torque motor 4431, etc. The specific configuration can be set according to actual needs, and there are no restrictions here.

[0110] Understandably, in some other embodiments, the output shaft of the motor 4431 may also be directly connected to the second shaft of the take-up roller 442 to directly drive the take-up roller 442 to rotate.

[0111] Optionally, there can be two traction ropes 43, which are respectively set at both ends of the winding roller 442 and wound in the direction of each other. There are two guide rollers, rotating bearings, lifting blocks 45 and limiting rods 46, which correspond one to one. The two limiting rods 46 are respectively located inside the two vertical rods 411, and the two lifting blocks 45 are respectively connected to the limiting rods 46. Thus, the lifting plate 42 can be driven to move along the height direction of the tower body 20 simultaneously by the two traction ropes 43 and the lifting blocks 45, so that the lifting movement of the lifting plate 42 is more stable and reliable.

[0112] Please refer to it again. Figure 1 and Figure 2 In some embodiments, the lifting device 40 further includes a fence 47, which is disposed on the side of the lifting plate 42 away from the ground. The fence 47, the lifting plate 42, and the fixed ladder 41 together form a lifting platform. The lifting platform has an opening along the height direction of the tower body 20, and the opening of the lifting platform faces away from the ground. Thus, when the operator moves along the height direction of the tower body 20 with the lifting plate 42, the fence 47 can surround the operator to protect the operator.

[0113] Optionally, the fence 47 also includes a first baffle, a second baffle, a third baffle, and a fourth baffle. The first baffle, the second baffle, the third baffle, and the fourth baffle are all located on the side of the lifting platform 42 away from the ground and are arranged sequentially around the outer perimeter of the lifting platform 42. The first baffle and the second baffle are spaced apart. The first baffle is connected to one of the vertical bars 411 of the fixed ladder 41, and the second baffle is connected to the other vertical bar 411 of the fixed ladder 41. The third baffle and the fourth baffle are located on the side of the lifting platform 42 away from the fixed ladder 41, and the third baffle is connected to the first baffle, and the fourth baffle is connected to the second baffle. The third baffle and the fourth baffle are snap-fitted together, so that the side of the fence 47 away from the fixed ladder 41 can be opened and closed, which facilitates the operator to enter or leave the lifting platform, thereby facilitating the operator's maintenance of the signal tower 1.

[0114] In some embodiments, considering the relatively high height of the signal tower 1, the end of the tower body 20 facing away from the base 10 is prone to swaying relative to the base 10. Therefore, the signal tower 1 further includes a reinforcing ring 60 and a reinforcing connector 70. The reinforcing ring 60 surrounds the outer periphery of the tower body 20, and its size is smaller than that of the base 10 along the height direction perpendicular to the tower body 20. The two ends of the reinforcing connector 70 are respectively connected to the reinforcing ring 60 and the base 10, and the reinforcing connector 70 has an inclined angle relative to the height direction of the tower body 20. This allows the tower body 20, the reinforcing ring 60, the reinforcing connector 70, and the base 10 to form a stable triangular or right-angled trapezoidal structure, thereby improving the structural stability of the signal tower 1.

[0115] Understandably, in other embodiments, the reinforcing ring 60 may also be a rectangular or polygonal structure, which can be set according to actual needs and is not limited here.

[0116] Optionally, there can be multiple reinforcing rings 60, which are spaced apart along the height direction of the tower body 20. For example, when there are three reinforcing rings 60, they can be respectively set at the bottom, top, and middle positions of the tower body 20 along its own height direction, thereby making the overall structure of the signal tower 1 more stable and reliable. At this time, the fixed ladder 41 can also be connected to the reinforcing rings 60 at the top of the tower body 20, thereby reserving installation space between the fixed ladder 41 and the tower body 20 for the installation of the shock absorption component 30, or facilitating the operator to manually climb the fixed ladder 41. It also makes the structure formed by the connection between the lifting device 40, the base 10, and the tower body 20 more stable, avoiding the situation where the weight of the side of the lifting device 40 away from the tower body 20 suddenly increases when the operator stands on the lifting plate 42, which could lead to the structural instability of the signal tower 1, thereby improving the structural reliability of the signal tower 1.

[0117] Optionally, considering that the support plate 50 is located on one side of the tower body 20 and the size of the support plate 50 is relatively large, there may be a situation where the reinforcement connector 70 cannot be installed in the original position due to the obstruction of the support plate 50. Based on this, the support plate 50 is provided with a through hole for the reinforcement connector 70 to pass through, thereby making the structure of the signal tower 1 more stable and reliable.

[0118] Optionally, there may be multiple reinforcing connectors 70, which are arranged evenly and at intervals in sequence, thereby making the outer periphery of the tower body 20 more stable.

[0119] In some embodiments, the reinforcing connector 70 is a reinforcing rope, which on the one hand allows the through hole on the support plate 50 to be made of an excessively large size, thus ensuring the structural reliability of the support plate 50, and on the other hand facilitates the installation of the reinforcing connector 70 and reduces the risk of the reinforcing connector 70 interfering with other structures.

[0120] Optionally, the base 10 is provided with a reinforcing block 80, and the end of the reinforcing block 80 facing away from the base 10 is provided with a mounting ring. The end of the reinforcing connector 70 facing away from the reinforcing block 80 passes through the mounting ring, thereby facilitating the connection between the reinforcing connector 70 and the base 10.

[0121] Understandably, in other embodiments, the reinforcing connector 70 may also be a reinforcing rod or a reinforcing plate, etc., which can be set according to actual needs and is not limited here.

[0122] In some embodiments, the signal tower 1 is also provided with anchor bolts 90 and the base 10 is provided with fixing holes. The anchor bolts 90 pass through the fixing holes and are connected to the ground, concrete or structural components, thereby improving the reliability of the connection between the base 10 and the ground, concrete or structural components, making the signal tower 1 more stable and reliable relative to the ground, concrete or structural components.

[0123] In some embodiments, a lightning rod 100 is provided at the top of the tower body 20 (i.e., the end of the tower body 20 away from the base 10), which can protect the signal tower 1 and reduce the risk of the signal tower 1 being struck by lightning.

[0124] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
