Description

[0002] In order to meet the rapid development of the communications industry, a considerable number of communication towers need to be installed with mobile communication antennas to meet people's higher requirements for network service quality, signal coverage, etc. The communication antennas of existing communication towers are usually located at the top of the communication tower antenna bracket. Most of the antennas are made of aluminum and operate at high altitudes for a long time. Under strong wind interference, due to the lack of effective vibration elimination measures, it is easy to cause the communication tower body to produce a large vibration frequency and amplitude, which may affect the signal reception performance at the least, or even cause the communication tower to bend and break as a whole.

[0003] In order to reduce the vibration of the communication tower structure, dampers are installed on the existing communication towers. However, the existing communication tower dampers have a simple structure and have a poor shock-absorbing effect on the communication tower.

[0042] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0043] Example 1

[0044] This embodiment provides a rooftop communication tower interlayer vibration damper, such as Figure 1-Figure 7 As shown, it includes a plurality of first damping units 1 that can be installed in the bottom interlayer (the bottom interlayer is at the lower end of the communication tower, or called the lower end interlayer) and the top interlayer (the top interlayer is at the upper end of the communication tower, or called the upper end interlayer) of the communication tower. The plurality of first damping units 1 can be evenly arranged between any two adjacent layers of tower frames 12 on the roof communication tower. The first damping unit 1 is vertically arranged on the periphery of the communication tower and its top and bottom ends are respectively connected to the upper and lower adjacent communication tower frames 12.

[0045] The first damping unit 1 includes a first damper 101 and a first heating coil 102. The first damper 101 includes a movable rod body at the upper part and a fixed rod body at the lower part. The first damper 101 is an existing viscous damper (the viscous damper belongs to the existing known technology, so its structure will not be elaborated too much). The first heating coil 102 is sleeved on the outside of the fixed rod body of the first damper 101. The top end of the movable rod body and the bottom end of the fixed rod body of the first damper 101 are respectively hinged at the connection parts 121 of the upper and lower adjacent communication towers 12, which can reduce the vibration conduction of the connection parts 121 of the communication towers 12. The number of the first damping units 1 is sixteen. The sixteen first damping units 1 are evenly divided into two groups (eight first damping units 1 are one group, one group is distributed in the upper interlayer and one group is distributed in the lower interlayer). The two groups of first damping units 1 are respectively arranged in the form of rectangular arrays on the periphery of the upper interlayer and the lower interlayer of the communication tower 12.

[0046] In this embodiment, in any two adjacent layers of tower frames 12, the bottom of the upper tower frame 12 and the top of the lower tower frame 12 are each divided into eight connecting parts 121; wherein, each of the four corners of the bottom of the upper tower frame 12 is divided into two connecting parts 121, and each of the four corners of the bottom of the lower tower frame 12 is distributed with two connecting parts 121, and the eight connecting parts 121 of the upper tower frame 12 and the eight connecting parts 121 of the lower tower frame 12 are arranged one by one, such as Figure 1 Specifically, two connecting parts 121 are respectively arranged at the two ends of the four side surfaces of the bottom periphery of the upper-level tower 12, so a total of eight connecting parts 121 are arranged at the bottom periphery of the upper-level tower 12 (equivalent to two connecting parts 121 being arranged at each of the four corners of the tower 12). Figure 1 Then, eight first damping units 1 are evenly arranged between each layer (i.e., between layers of towers 12), and the eight first damping units 1 are respectively arranged between the eight connecting parts 121 at the bottom of the upper tower 12 and the eight connecting parts 121 at the top of the lower tower 12, and the top end of the movable rod of each first damping unit 1 is hinged to the connecting part 121 of the upper tower 12, and the bottom end of the fixed rod is hinged to the connecting part 121 of the lower tower 12, as shown in FIG. Figure 1 , Figure 5 and Figure 6 shown.

[0047] When the top structure (upper end) of the communication tower vibrates, the eight first damping units 1 between the upper layers can effectively reduce the vibration of the top of the communication tower, while the eight first damping units 1 outside the bottom layers (lower layers) of the communication tower can further reduce the overall vibration of the communication tower structure above it, so that the bottom of the communication tower remains stable and damage to the communication tower is avoided. The first heating ring 102 can also be used to heat the corresponding part of the first damper 101, which can ensure that the damping medium 402 in the first damping unit 1 is in a normal state and can work normally, thereby avoiding reducing the shock absorption effect.

[0048] It also includes a second damping unit 2 and a third damping unit 3 for fixedly installed on the top of the communication tower. A central axis is arranged on the top of the communication tower, and the axis of the central axis coincides with the center line of the communication tower. The second damping unit 2 and the third damping unit 3 are installed on the central axis from top to bottom; the second damping unit 2 and the third damping unit 3 both include a first vibration absorbing unit 4, a second vibration absorbing unit 5, a third vibration absorbing unit 6 and a fixing ring 7 capable of absorbing vibrations of the communication tower.

[0049] Specifically, the fixed ring 7 includes an inner ring 701 and an outer ring 702, the inner ring 701 is fixedly sleeved on the outside of the central axis of the communication tower, the inner ring 701 and the outer ring 702 are concentrically arranged and form a concentric circle structure with each other, and the first vibration absorbing unit 4 and the second vibration absorbing unit 5 are fixedly connected between the inner ring 701 and the outer ring 702, and the number of the first vibration absorbing unit 4, the second vibration absorbing unit 5 and the third vibration absorbing unit 6 in the fixed ring 7 is eight, and the eight first vibration absorbing units 4, the second vibration absorbing units 5 and the third vibration absorbing units 6 are all arranged in a cross shape inside the fixed ring 7, and the two diagonal first vibration absorbing units 4, the second vibration absorbing units 5 and the third vibration absorbing units 6 are all on the same axis, and the first vibration absorbing units 4, the second vibration absorbing units 5 and the third vibration absorbing units 6 arranged in a cross shape can absorb vibrations in all directions of the communication tower.

[0050] The end surface of the outer ring 702 is evenly provided with a plurality of ears 7021 around its axis, eight ears 7021 are provided and are arranged one-to-one corresponding to the second vibration absorbing units 5, one second vibration absorbing unit 5 is evenly connected between each ear 7021 and each inner ring 701, and a third vibration absorbing unit 6 is provided on the second vibration absorbing unit 5.

[0051] like Figure 3 and Figure 4As shown, the first vibration absorbing unit 4 includes a sealing tube 401, a damping medium 402, vibration absorbing micro-beads 403 and a second heating ring 404. The two ends of the sealing tube 401 are fixedly connected to the outer surface of the inner ring 701 and the inner surface of the outer ring 702 respectively. The damping medium 402 is filled in the sealing tube 401 and fills the inside thereof. The damping medium 402 is an elastic damping material, which can be damping rubber, damping liquid, etc. The number of vibration absorbing micro-beads 403 is several and the several vibration absorbing micro-beads 403 are evenly distributed in the damping medium 402 and blended with the damping medium 402. The material of the vibration absorbing micro-beads 403 can be metal and crystal materials (such as graphene, sound absorbing crystals, etc.), or granular materials (such as gravel, crystalline particles, etc.). The second heating coil 404 is sleeved on the outside of the sealing tube 401. When the second heating coil 404 is energized, it can heat the damping medium 402 in the sealing tube 401 to prevent its damping performance from being affected by the excessively low external temperature. When the communication tower is vibrated by strong wind, it will drive the first vibration absorbing unit 4 in the second damping unit 2 and the third damping unit 3 to vibrate. At this time, the vibration absorbing micro-beads 403 will be subjected to the energy dissipation effect of the multi-directional damping medium 402, which fully corresponds to the vibration forms of the communication tower at different frequencies and amplitudes. The multiple vibration absorbing micro-beads 403 are interconnected through the damping medium 402 to form a mass-spring 502-damper system, so that it can have the energy dissipation effect in the corresponding direction under different vibration forms of the communication tower, thereby absorbing and reducing the vibration of the communication tower, and achieving a good shock-absorbing effect.

[0052] like Figure 3 and Figure 4 As shown, the second vibration absorbing unit 5 includes a circular tube 501, a spring 502 and a damping ball 503. The circular tube 501 is fixedly connected between the inner ring 701 and the outer ring 702 and is vertically corresponding to the sealing tube 401 and is horizontally parallel to each other. The spring 502 is arranged inside the circular tube 501 and one end is fixedly connected to the inner surface of the outer ring 702. The damping ball 503 is fixedly connected to the other end of the spring 502 and can slide laterally along the inside of the circular tube 501. When the communication tower vibrates, the damping ball 503 in the circular tube 501 can vibrate laterally along the vibration direction of the communication tower as a tuning mass unit, and the spring 502 can exert a force on the damping ball 503 in the opposite direction of the running direction, so that the vibration generated by a part of the communication tower can be offset by the activity of the damping ball 503, thereby reducing the natural frequency of the communication tower, and further reducing the vibration of the communication tower.

[0053] like Figure 3 and Figure 4As shown, the third vibration absorbing unit 6 includes a spiral tube 601 and a ball 602. The spiral tube 601 is spirally wound on the outer surface of the circular tube 501 and fixedly connected thereto. Both ends of the spiral tube 601 are in a closed state. There are a plurality of balls 602, and the plurality of balls 602 are arranged inside the spiral tube 601 and can roll therein. The balls 602 inside the spiral tube 601 can roll along the inside of the spiral tube 601 as the communication tower vibrates. When the balls 602 roll along the spiral inside the spiral tube 601, they can apply an inertial force with full degrees of freedom in a three-dimensional space to the spiral tube 601, so that part of the inertial force in the opposite direction to the vibration direction of the communication tower can offset part of the vibration force of the communication tower, thereby reducing the natural frequency of the communication tower.

[0054] Although the third damping unit 3 and the second damping unit 2 have the same structural composition, there are also differences, as follows: the diameter of the outer ring 702 in the third damping unit 3 is greater than the diameter of the outer ring 702 in the second damping unit 2, the lengths of the sealing tube 401, the circular tube 501 and the spiral tube 601 in the third damping unit 3 are greater than the lengths of the sealing tube 401, the circular tube 501 and the spiral tube 601 in the second damping unit 2, and the ear 7021 in the second damping unit 2 is located on the upper end surface of the outer ring 702, and the ear 7021 in the second damping unit 2 is located on the upper end surface of the outer ring 702, and accordingly, the second vibration absorbing unit 5 and the third vibration absorbing unit 6 are located directly above the first vibration absorbing unit 4. The ear 7021 in the third damping unit 3 is located on the lower end surface of the outer ring 702, and accordingly, the second vibration absorbing unit 5 and the third vibration absorbing unit 6 are located directly above the first vibration absorbing unit 4.

[0055] Since the lengths of the first vibration absorbing unit 4, the second vibration absorbing unit 5 and the third vibration absorbing unit 6 in the second damping unit 2 are different from those of the first vibration absorbing unit 4, the second vibration absorbing unit 5 and the third vibration absorbing unit 6 in the third damping unit 3, when the communication tower vibrates, the travel paths of the vibration absorbing beads 403, the damping balls 503 and the rolling balls 602 in the second damping unit 2 are different from those of the vibration absorbing beads 403, the damping balls 503 and the rolling balls 602 in the third damping unit 3. Therefore, it is prevented that the structures in the second damping unit 2 and the structures in the third damping unit 3 are driven to move synchronously when the communication tower vibrates, and it is effectively prevented that the second damping unit 2 and the third damping unit 3 resonate with the communication tower and enhance the vibration frequency of the communication tower.

[0056] The vibration isolation damper of the present application can absorb and reduce the vibration energy of the communication tower itself, reduce the vibration of the communication tower, reduce vibration conduction, ensure the stability of the overall structure of the communication tower, and monitor the various structures of the vibration isolation damper in real time so that relevant personnel can be informed of the vibration conditions of the communication tower in a timely manner. The ambient temperature at the top of the communication tower is monitored in real time, and the relevant structures are adjusted through the control unit to ensure that the damping medium is in a normal state and avoid affecting the shock absorption effect.

[0057] Example 2

[0058] This embodiment provides a rooftop communication tower (referred to as communication tower). A communication tower is a tall structure specially designed for installing and supporting wireless communication equipment. A rooftop communication tower refers to a communication device installed on the roof of a building, which is mainly used for transmitting and receiving wireless communication signals. The communication tower includes a multi-layer tower frame 12, and also includes the rooftop communication tower interlayer vibration damper, and eight of the first damping units 1 are evenly arranged between the layers of the tower frames 12 of two adjacent layers.

[0059] The tower also includes a damping monitoring system, which includes a first sensor 8 for monitoring the first damping unit 1, a second sensor 9 for monitoring the first vibration absorbing unit 4, a third sensor 10 for monitoring the second vibration absorbing unit 5, and a temperature sensor 11 for monitoring the ambient temperature at the top of the communication tower. The first sensor 8 is fixedly mounted at the bottom of the fixed rod of the first damper 101 and the detection end is penetrated inside the fixed rod. The fixed rod of the first damper 101 is filled with a damping medium 402. The second sensor 9 is fixedly mounted on the outer surface of the outer ring 702 at a position corresponding to the axis of the first vibration absorbing unit 4 and the detection end is penetrated inside the corresponding sealing tube 401. Each first vibration absorbing unit 4 A second sensor 9 is correspondingly provided. The first sensor 8 and the second sensor 9 can be pressure sensors, which can monitor the damping medium 402 in the first damper 101 and the sealing tube 401 in real time. When the first sensor 8 or the second sensor 9 detects that the pressure change of the damping medium 402 in the corresponding part is greater than the normal value when the communication tower is in a stable state, it proves that the damping medium 402 in the corresponding part may leak, which is convenient for relevant personnel to quickly know the pressure change of the corresponding structure and take countermeasures in time, so as to ensure the stability of the communication tower structure at all times; the third sensor 10 is fixedly installed on the outer surface of the inner ring 701 in the third damping unit 3 corresponding to the axis of the circular tube 501 The damping ball 503 in each third damping unit 3 is provided with a third sensor 10. The third sensor 10 can be a displacement sensor, which can detect the distance between the damping ball 503 and the third sensor 10 in each circular tube 501 in real time. The data detected by the third sensor 10 corresponding to each group of axes can be observed. When the third sensor 10 corresponding to one group of axes detects that the displacement range of the corresponding damping ball 503 is greater than the displacement ranges of the other groups of damping balls 503, it can be proved that the direction in which the communication tower is currently blown by strong wind is the same as the direction of the second vibration absorbing unit 5 of the group. At the same time, according to each third sensor 10 The activity range of the corresponding damping ball 503 is detected to analyze the vibration amplitude of the current communication tower, so that relevant personnel can know the current situation of the communication tower in real time; the temperature sensor 11 is fixedly installed on the outer surface of the outer ring 702 in the third damping unit 3, and the temperature sensor 11 can monitor the ambient temperature around it in real time. When the detected ambient temperature is too low and can affect the damping performance of the damping medium 402, the control unit will control the first heating coil 102 and the second heating coil 404 to heat up, and can heat the damping medium 402 in the first damper 101 and the sealing tube 401, so that it can always maintain the best damping performance, thereby achieving the best shock absorption effect on the communication tower.

[0060] It should be noted that the first heating coil 102, the second heating coil 404, the first sensor 8, the second sensor 9, the third sensor 10 and the temperature sensor 11 are all electrically connected to the external control unit through wires, and are all electrically connected to the external circuit. These heating coils and sensors facilitate real-time monitoring of the vibration of the communication tower and various structures of the damper, so that the damage of the damper can be known in time, and the stability of the communication tower can be ensured.

[0061] The beneficial effects of the technical solution of the present invention are:

[0062] (1) The first vibration absorbing unit 4, the second vibration absorbing unit 5 and the third vibration absorbing unit 6 in the inter-layer vibration damper of the roof communication tower can generate multiple different natural frequencies as the communication tower vibrates. At the same time, the structures in the first vibration absorbing unit 4, the second vibration absorbing unit 5 and the third vibration absorbing unit 6 restrain, rub or squeeze each other as the communication tower vibrates, so as to achieve the purpose of absorbing and reducing the vibration energy of the communication tower itself. A part of the multiple different natural frequencies can also offset the vibration of the communication tower itself, thereby further reducing the vibration of the communication tower. The setting of multiple first damping units 1 can not only reduce the vibration of the communication tower but also reduce the vibration conduction, thereby ensuring the stability of the overall structure of the communication tower and avoiding damage to the communication tower.

[0063] (2) The first sensor 8 and the second sensor 9 in the damping monitoring system can monitor the damping medium 402 in the first damping unit 1 and the first vibration absorbing unit in real time, and can monitor whether the damping medium 402 in the first damping unit 1 and the second vibration absorbing unit 5 leaks at the first time, so that relevant personnel can take timely response measures to ensure the stability of the communication tower structure. The third sensor 10 can monitor the vibration of the structure in the second vibration absorbing unit 5 in real time, so as to analyze the vibration frequency and amplitude of the current communication tower according to the data detected by the third sensor 10 in different directions, so that relevant personnel can know the vibration of the communication tower in time. The temperature sensor 11 can monitor the ambient temperature at the top of the communication tower in real time. When the temperature is low, the control unit controls the first heating coil 102 and the second heating coil 404 to heat the corresponding parts, so as to ensure that the damping medium 402 in the first damping unit 1 and the second vibration absorbing unit 5 is in a normal state, avoiding affecting the shock absorption effect, which is more intelligent and convenient.
