TECHNICAL FIELD
[0001] The present application relates to the technical field of communication base station tower, in particular to a polyurethane composite material anti-seismic communication base station tower. BACKGROUND
[0002] With the continuous evolution of 5G and even future communication technology, the communication base station tower as a key node of signal transmission becomes more and more important. The high dependence of modern society on communication makes it necessary for the communication base station to have extremely high stability and reliability, especially in the face of natural disasters such as earthquakes. Traditional communication base station towers are mostly constructed with steel main frames. In the past communication construction, steel has met the needs of supporting signal equipment and other requirements to some extent due to its high strength. However, with the passage of time and the increasing demand for communication stability, the limitations of traditional steel base station towers have gradually been exposed. The high density of steel makes the overall weight of the traditional communication base station tower heavier. In the event of an earthquake, the large mass will generate a strong inertial force, which will exert a huge stress on the tower structure, easily leading to deformation or even collapse of the tower body. For example, in some earthquake-prone areas, the traditional steel base station tower will tilt and the key connecting parts will break due to the inertial force caused by its own weight in slightly high magnitude earthquakes. Moreover, the traditional communication base station tower structure is mostly rigidly connected, and the ground vibration energy will quickly transmit to the entire tower under the action of seismic waves, lacking effective buffering and energy dissipation means. When a strong earthquake occurs, the tower body often cannot effectively absorb and consume seismic energy, resulting in instantaneous concentration of structural stress and causing structural damage. For example, a common traditional integrated steel tower may trigger a chain reaction and lead to rapid instability of the entire tower body once the stress on a certain part exceeds the yield strength of the steel in an earthquake.
[0003] In view of the above, to solve the technical problems proposed in this paper, a polyurethane composite material anti-seismic communication base station tower is proposed. SUMMARY

DETAILED DESCRIPTION
[0014] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application will be further described below in conjunction with specific embodiments. EMBODIMENT
[0015] As shown in Figures 1 to 8 ; a polyurethane composite material anti-seismic communication base station tower; the communication base station tower comprises: a tower base plate 1 installed on the ground, with a through hole in the middle; The buffer plates 11 are four in number and are evenly distributed at the four corners of the tower base plate 1; the upper end of the buffer plate 11 is provided with a cross slot 12; the four ends of the cross slot 12 are each provided with a spring; The tower body mounting plate 2 is provided with a support column 21 at the lower end of each of the four corners; each support column 21 is located in the center of the cross slot 12 of the buffer plate 11; the outer side of the support column 21 is connected with the four springs in the cross slot 12; The frame 3 is four in number and is evenly arranged at the four ends of the tower body mounting plate 2; the frame 3 is arranged in sections and is made of polyurethane composite material; The top column 31 is located at the top end of the frame 3, and the lower end of the top column 31 is connected with the steel rope 32; The shock absorbing well 4 is arranged on the ground and is located at the lower end of the tower base plate 1; the shock absorbing well 4 is provided with a counterweight column 41 suspended therein; the upper end of the counterweight column 41 is connected with the steel rope 32; The frame 3 is hingedly connected with the tower body mounting plate 2 and is inclined upward and connected with the outer side of the top column 31; the sections of the frame 3 are provided with mounting rings 33, and the lower end of the mounting ring 33 is provided with a sliding groove 34; part of the lower section of the frame 3 is embedded in the sliding groove 34, and the sliding groove 34 is provided with a spring inside; The shock absorbing well 4 is provided with a metal box 42 inside; the inner wall of the metal box 42 is provided with a hydraulic telescopic device 43; the output end of the hydraulic telescopic device 43 is ball-jointed with the outer ring of the counterweight column 41; The specific working process is as follows: When the base station tower is in use, the tower base plate 1 is stably installed on the ground as a connecting part of the communication base station tower and the ground, and the through hole formed in the middle can be used for the steel rope 32 to pass through; the four corners of the tower base plate 1 are evenly distributed with four buffer plates 11, the upper end of the buffer plate 11 is provided with a cross groove 12 structure, and the four ends of the cross groove 12 are provided with springs; the tower body mounting plate 2 is a key part for bearing the upper structure of the base station tower, the support column 21 arranged at the lower end of the four corners is accurately located at the central position of the cross groove 12 of the buffer plate 11, and the outer side of the support column 21 is closely connected with the four springs in the cross groove 12; when an earthquake occurs, irregular vibration will be generated on the ground, which will be quickly transmitted to the tower base plate 1, so that the tower base plate 1 swings with the ground, at this time, the tower body mounting plate 2 is stably kept under the action of the gravity of the upper frame 3 and other structures, so that the support column 21 at the lower end of the tower body mounting plate 2 swings in the cross groove 12, and the support column 21 transmits the force generated by the vibration to the spring through the connection with the spring; after the spring is stressed, elastic deformation will occur, and the spring absorbs part of the earthquake energy through its own deformation, and at the same time generates a spring force opposite to the vibration direction to exert a reverse force on the support column 21 and the tower body mounting plate 2 connected therewith, so as to buffer the vibration and reduce the vibration amplitude of the tower body mounting plate 2; reducing the vibration amplitude of the tower body mounting plate 2 means reducing the structural stress of the tower body caused by the ground vibration; this effectively avoids the problems of structural deformation, loose connection and other problems of the tower body caused by excessive vibration in the earthquake, greatly reducing the risk of damage to the tower body caused by the ground vibration; By making the number of frames 3 four, which are evenly arranged at the four ends of the tower body mounting plate 2, a main support structure of the communication base station tower is formed; the frame 3 is arranged in sections, and the connection between the frame 3 and the tower body mounting plate 2 adopts a hinged connection mode, and the frame 3 is all inclined and connected to the outside of the top column 31; when the frame 3 is subjected to external force, it can produce a certain angle of rotation through the hinge point; according to the principle of mechanics, when the external force acts on the frame 3, the force can be decomposed into a component along the axis of the frame 3 and a component perpendicular to the axis of the frame 3; through the rotation of the hinge point, the frame 3 can change its angle, so that part of the external force is dispersed through the rotation of the frame 3, avoiding the excessive concentration of external force in the local part of the frame 3; And at the same time, the frame 3 is provided with mounting rings 33 between the segments, the lower end of the mounting ring 33 is provided with a sliding groove 34, part of the lower segment of the frame 3 is embedded into the inside of the sliding groove 34, and the inside of the sliding groove 34 is provided with a spring; when the earthquake occurs, due to the complexity of the ground vibration, the relative displacement between the segments of the frame 3 will be generated due to the vibration; when the relative displacement between the upper segment and the lower segment of the frame 3 occurs, the spring in the sliding groove 34 will be compressed or stretched; according to the working principle of the spring, the spring will absorb energy in the deformation process, and generate a spring force opposite to the direction of displacement, so as to buffer the impact force generated by the displacement, further consume the earthquake energy, reduce the excessive stress generated between the segments of the frame 3 due to the relative displacement, and ensure the integrity of the frame 3 structure; The top column 31 is arranged at the upper end of the frame 3, and the lower end of the top column 31 is hung with a counterweight column 41 through a steel rope 32, the counterweight column 41 is subjected to the action of its own gravity, the counterweight column 41 pulls the top column 31 downward, and the top column 31 transmits the pulling force of the counterweight column 41 to the frame 3, so that the frame 3 generates stress concentrated to the middle part, and the stability of the frame 3 is improved; and by adding a metal box 42 in the shock absorption well 4, the metal box 42 supports the shock absorption well 4 in the process of the earthquake, so that the deformation of the shock absorption well 4 is avoided to a certain extent; and the hydraulic telescopic device 43 is hinged on the inner wall of the metal box 42, and the output end of the hydraulic telescopic device 43 is connected to the outer ring of the counterweight column 41 in a ball joint manner; when the earthquake occurs, the ground vibration will be transmitted to the counterweight column 41 through the steel rope 32, so that the counterweight column 41 shakes; the hydraulic telescopic device 43 can be stretched and contracted according to the movement of the counterweight column 41; when the counterweight column 41 shakes, the force is generated to the hydraulic telescopic device 43, so that the hydraulic oil flows in the hydraulic telescopic device 43; the hydraulic oil generates damping effect in the flowing process, and the damping effect can consume the shaking of the counterweight column 41; at the same time, the hydraulic telescopic device 43 plays a role of constraint and buffering to the movement of the counterweight column 41, so that the movement is more stable, and the adverse effect on the whole structure due to excessive shaking is avoided; And when the frame body shakes in the process of the earthquake, the frame body will drive the top column 31 to shake, the top column 31 pulls the counterweight column 41 through the steel rope 32 in the process of shaking, so that the counterweight column 41 moves upward, while the counterweight column 41 moves downward due to its own gravity, the counterforce of the downward movement of the counterweight column 41 is transmitted to the top column 31, and then transmitted to the frame 3 through the top column 31, so that the top column 31 and the frame 3 generate a force opposite to the swing of the earthquake, thereby reducing the swing amplitude of the frame 3 and improving the stability of the base station tower. Embodiment
[0016] As Figures 2 to 8The outer side of the top column 31 is provided with two pull ropes 35, and two rotating shafts are distributed between the two pull ropes 35, the upper rotating shaft is sleeved with two pulleys one 36, and the lower rotating shaft is sleeved with two pulleys two 37; The number of the steel ropes 32 at the lower end of the top column 31 is two, and the two steel ropes 32 are respectively sleeved on the outer circle of the two pulleys one 36, then pass through the pulleys one 36, and are sleeved on the pulleys two 37, and then are connected to the upper end of the counterweight column 41; The outer circle of each pulley one 36 is provided with an arc plate 38, so that the steel rope 32 is located between the arc plate 38 and the pulley one 36; the outer circle of each pulley two 37 is provided with an arc plate 38, so that the steel rope 32 is located between the arc plate 38 and the pulley two 37; The specific working process is as follows: The top column 31 is a key component of the top of the communication base station tower, the two pull ropes 35 are provided on the outer side of the top column 31, and the two rotating shafts are distributed between the two pull ropes 35, which provide rotating support for the pulleys one 36 and the pulleys two 37; the pulleys one 36 and the pulleys two 37 are suspended below the top column 31, so that the center of the top column 31 is lowered, and the top column 31 is more stable; and the two pulleys one 36 are sleeved on the rotating shaft above the pull rope 35, and the two pulleys two 37 are sleeved on the rotating shaft below the pull rope 35; When the earthquake occurs, the inertia force generated by the large mass of the counterweight column 41 can be more effectively transmitted to the top column 31 and the frame 3 through the steel rope 32, the pulley one 36 and the pulley two 37, and more vibration energy generated by the earthquake can be offset; at the same time, the friction force generated between the pulley, the steel rope 32 and the arc plate 38 further consumes energy, so that the efficiency of the energy offset and consumption of the whole top column 31 and the counterweight column 41 shock absorption structure is greatly improved; this not only significantly reduces the vibration amplitude of the frame 3 and the top column 31, effectively protects the tower top equipment from damage caused by excessive vibration, but also greatly reduces the risk of the communication base station tower collapsing due to excessive vibration, and provides more reliable protection for the normal operation of the communication equipment; and at the same time, in the process of vibration of the top column 31, the pulleys one 36 and the pulleys two 37 rely on their own gravity to generate a damper effect on the top column 31, so that the pulleys one 36 and the pulleys two 37 rely on their own gravity to generate a counter force on the top column 31 in the process of shaking of the top column 31; reduce the shaking of the top column 31, and at the same time, the two steel ropes 32 are sleeved on the pulleys one 36 and the pulleys two 37, so that the two steel ropes 32 form an "8" structure, and the pulleys one 36 and the pulleys two 37 are limited, the swing amplitude of the top column 31 is reduced, and the swing amplitude of the top column 31 is further reduced; The arc-shaped plate 38 provided on the outer ring of each pulley 36 and pulley 2 37 has multiple functions; from a mechanical point of view, the arc-shaped plate 38, pulley 1 36 and pulley 2 37 jointly constrain the steel rope 32 to ensure that the movement trajectory of the steel rope 32 on the pulley is stable; the steel rope 32 is located between the arc-shaped plate 38 and the pulley, and the arc-shaped plate 38 can prevent the steel rope 32 from falling off the pulley when moving at high speed or subjected to a large external force, thereby ensuring the continuity of force transmission; at the same time, in the process of contact between the steel rope 32 and the pulley and the arc-shaped plate 38, friction will be generated on the contact surface due to the movement of the steel rope 32; according to the friction generation mechanism, this friction will hinder the movement of the steel rope 32, thereby reducing the energy consumption of the steel rope 32 itself, and then reducing the shaking amplitude of the top column 31 and the frame 3. Example
[0017] like Figures 2 to 8 Located at the lower end of the mounting ring 33 between the adjacent frames 3 is tilted with a telescopic buffer rod 39, located at the upper end of the mounting ring 33 between the adjacent frames 3 is tilted with a telescopic buffer rod 2 391; The specific work flow is as follows; In the frame 3 structure of the communication base station tower, the mounting ring 33 divides the frame 3 into upper and lower parts, playing a key role in connection and transition; the telescopic buffer rod 1 39 arranged obliquely between adjacent frames 3 at the lower end of the mounting ring 33, and the telescopic buffer rod 2 391 arranged obliquely between adjacent frames 3 at the upper end of the mounting ring 33, work closely with the frame 3; when an earthquake occurs, the ground vibration causes complex relative displacement and angle changes between the various segments of the frame 3; because the frame 3 is tilted upward and arranged in segments, under the action of earthquake waves, each segment will experience different degrees of deformation such as torsion, tension and compression due to the vibration; the telescopic buffer rod 1 39 and the telescopic buffer rod 2 391 can be adjusted accordingly according to the deformation of the frame 3; Taking the lower end of the mounting ring 33 as an example, when the adjacent frames 3 are displaced relatively closer or farther away due to vibration, the telescopic buffer rod 1 39 adapts to this displacement change through its own expansion and contraction, thereby preventing the connection of the frame 3 from being damaged due to excessive force; at the same time, due to its inclined setting, when the angle of the frame 3 changes, the telescopic buffer rod 1 39 can also provide additional support force by adjusting its own inclination angle to maintain the stability of the frame 3 structure; the telescopic buffer rod 2 391 at the upper end of the mounting ring 33 works in a similar way, except that it is aimed at the deformation of the frame 3 part above the mounting ring 33. Example
[0018] like Figures 1 to 8 As shown; the polyurethane composite material is based on polyurethane resin and is added with glass fiber and carbon fiber; The specific work flow is as follows; The polyurethane composite material is selected from polyurethane composite materials; the composite material takes polyurethane resin as a matrix, wherein glass fibers and carbon fibers are added; the polyurethane resin has good flexibility and adhesion, and can tightly bond the glass fibers and carbon fibers together to form a whole that works cooperatively; the glass fibers and carbon fibers greatly enhance the strength and toughness of the composite material by virtue of their excellent mechanical properties; the glass fibers have high tensile strength and can withstand large tension; the carbon fibers have high modulus and high strength, and thus perform well when subjected to various external forces such as bending and compression; through the composite mode, the frame 3 has good mechanical properties and can withstand large external forces, meeting the bearing requirements of the communication base station tower in various environments.
