Description

Technical Field

[0001] This utility model relates to the field of communication base station component technology, and in particular to a communication base station component with a foldable signal reflector. Background Technology

[0002] The location of the antenna reflector in a communication base station depends mainly on the type of antenna, but the most common location is right behind the radiating element array (vibrator). The most common scenario (macro base station panel antenna) is that the reflector is located behind the radiating element array (that is, the vibrators that are responsible for transmitting and receiving signals).

[0003] Multiple telecommunications operators and base station construction companies have reported that traditional reflectors, lacking effective wind resistance adjustment structures, are prone to turbulent impacts when directly facing strong winds in windy conditions. This results in excessive wind resistance, significantly increasing the load on the towers and raising the risk of base station collapse year-on-year during extreme weather events such as typhoons.

[0004] Even more troublesome is that the continuous vibration caused by strong winds can lead to fatigue damage at the connection between the reflector and the support. At the same time, rainwater and salt spray directly wash over the edge of the reflector, accelerating metal corrosion and shortening the antenna's lifespan by about 15% to 20%. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a communication base station component with a foldable signal reflector. This solves the technical problem that traditional reflectors, lacking an effective wind resistance adjustment structure, are prone to turbulent impacts when directly facing strong winds in windy conditions, resulting in excessive wind resistance, significantly increasing the load on the tower, and increasing the risk of base station collapse under extreme weather conditions such as typhoons.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A communication base station assembly with a foldable signal reflector includes a base station bracket, on which three sets of mounting brackets are fixedly installed. Three sets of antenna assemblies are mounted on the base station bracket, each antenna assembly being mounted on the base station bracket via a mounting bracket. Each antenna assembly includes an aluminum reflector with a micro-radiating element inside. The aluminum reflector has a flow-guiding mechanism for adjusting wind resistance, and mounting slots for mounting the flow-guiding mechanism are provided at both the upper and lower ends of the aluminum reflector.

[0010] Preferably, the flow guiding mechanism includes a front baffle, with flow guide plates fixedly installed on both sides of the front baffle. The separated ends of the two flow guide plates are both airfoil-shaped streamlined curved surfaces, and the radius of curvature of the leading edge of the two flow guide plates is greater than the thickness of the side walls of the aluminum reflector. A first mounting rod is provided between the upper and lower ends of each of the two flow guide plates, and a first bolt is threaded onto each of the two first mounting rods and the flow guide plates. The two first mounting rods are respectively installed in two mounting slots opened in the aluminum reflector.

[0011] Preferably, the flow guiding mechanism includes a porous metal damping mesh with ventilation holes. The diameter of the ventilation holes is between 5 and 8 mm, and the opening rate of the ventilation holes on the porous metal damping mesh is 60% to 70%. Connecting rods are provided at both the upper and lower ends of the porous metal damping mesh, and two second bolts are provided on each of the two connecting rods. The two second bolts are respectively threaded onto the upper and lower ends of the porous metal damping mesh. Two second mounting rods are fixedly installed on each of the two connecting rods, and the two second mounting rods are snapped into the mounting grooves opened in the aluminum reflector.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this new invention, by adding a deflector and a front baffle to the outer edge of the windward side of the reflector, and by using an airfoil-shaped streamlined curved surface to cover both sides of the aluminum reflector, the airflow path is reconstructed, transforming the direct impact turbulence into surface laminar flow. This reduces the wind resistance of the aluminum reflector in the communication base station assembly under strong wind conditions, improves the safety of the aluminum reflector, significantly reduces the load on the tower, reduces the risk of collapse in strong wind environments, and also suppresses vibration fatigue and corrosion of the communication base station, increasing antenna lifespan.

[0021] This application provides a communication base station component with a foldable signal reflector, which effectively solves the technical problem that traditional reflectors, due to the lack of an effective wind resistance adjustment structure, are prone to turbulent impact when facing strong winds in windy environments, resulting in excessive wind resistance, significantly increasing the load on the tower, and increasing the risk of base station collapse under extreme weather conditions such as typhoons.

[0022] Example 1

[0023] like Figure 1-5 As shown, the technical solution in this application aims to effectively address the problem that traditional reflectors, due to the lack of an effective wind resistance adjustment structure, are prone to turbulent impacts when directly facing strong winds in windy conditions, resulting in excessive wind resistance, significantly increasing the load on the tower, and increasing the risk of base station collapse under extreme weather conditions such as typhoons. The overall approach is as follows:

[0024] To address the problems existing in the prior art, this utility model provides a communication base station assembly with a foldable signal reflector, including a base station bracket 8. Three sets of mounting brackets 7 are fixedly installed on the base station bracket 8, and three sets of antenna assemblies are provided on the base station bracket 8. Each set of antenna assemblies is installed on the base station bracket 8 through the mounting brackets 7. Each set of mounting brackets 7 is provided with a locking ring and a locking nut to fix the antenna assembly. The antenna assembly can be quickly disassembled. The antenna assembly includes an aluminum reflector 1, which has multiple rows and columns of tiny radiating elements. The aluminum reflector 1 reflects electromagnetic waves that might otherwise be scattered backward forward, forming a stronger directional beam (main lobe) and improving the antenna gain in the target direction.

[0025] The aluminum reflector 1 is equipped with a flow guiding mechanism to adjust wind resistance. The flow guiding mechanism can reduce the wind resistance of the aluminum reflector 1, thereby improving safety. The aluminum reflector 1 has mounting slots 2 at both the top and bottom for installing the flow guiding mechanism. Through the mounting slots 2, the aluminum reflector 1 can be equipped with different technical structures that can reduce wind resistance. The aluminum reflector 1 in this communication base station assembly is foldable.

[0026] Example 2

[0027] Based on Example 1, such as Figure 2 and Figure 3 As shown, the airflow guiding mechanism includes a front baffle 6, with airflow guide plates 5 fixedly installed on both sides of the front baffle 6. The separated ends of the two airflow guide plates 5 are both airfoil-shaped streamlined curved surfaces and cover both sides of the aluminum reflector plate 1. The radius of curvature of the leading edge of the two airflow guide plates 5 is greater than the thickness of the side walls of the aluminum reflector plate 1, and the front end of the front baffle 6 is arc-shaped to ensure that the direct airflow smoothly transitions to both sides. Both the airflow guide plates 5 and the front baffle 6 are made of glass fiber reinforced plastic. The two airflow guide plates 5 cover the edge of the aluminum reflector plate 1 (the easily corroded parts) to block rainwater / salt spray from directly washing away the surface and slow down the corrosion of the aluminum reflector plate 1. This structure is more suitable for typhoon / highly corrosive coastal areas (resistant to instantaneous wind pressure + corrosion prevention).

[0028] Each of the two guide plates 5 has a first mounting rod 3 between its upper and lower ends. The two first mounting rods 3 are threadedly connected to the guide plates 5 with first bolts 4. The two first mounting rods 3 are respectively installed in the two mounting slots 2 opened in the aluminum reflector plate 1. During installation, the first bolts 4 can be used for installation. When the first bolts 4 are threadedly locked with the guide plates 5 and the first mounting rods 3 are engaged in the two mounting slots 2 opened in the aluminum reflector plate 1, the installation is considered complete.

[0029] Example 3

[0030] Based on Example 1, such as Figure 4 and Figure 5 As shown, the airflow guiding mechanism includes a porous metal damping mesh 12, on which ventilation mesh holes 13 are formed. The diameter of the ventilation mesh holes 13 in the porous metal damping mesh 12 is between 5 and 8 mm, which can balance wave transmittance and turbulence control. The opening ratio of the ventilation mesh holes 13 in the porous metal damping mesh 12 is 60% to 70%, which can effectively ensure airflow. The ventilation mesh holes 13 in the porous metal damping mesh 12 can cut the incident airflow into micro-scale jets, triggering the transition from laminar to turbulent flow in advance, thereby suppressing the amplitude of wind-induced vibration and reducing the risk of structural fatigue. Moreover, the porous metal damping mesh 12 blocks less than 0.5 dB of 5G signals (measured in the Sub-6 GHz band), making it more suitable for sandstorm / continuous strong wind inland areas (dissipative turbulence + vibration resistance).

[0031] The porous metal damping mesh 12 has connecting rods 10 at both the top and bottom ends, and each connecting rod 10 has a second bolt 11. The two second bolts 11 are respectively threaded onto the top and bottom ends of the porous metal damping mesh 12. Each connecting rod 10 has a second mounting rod 9 fixedly installed on it. The two second mounting rods 9 are snapped into the mounting groove 2 opened in the aluminum reflector plate 1. When installing the porous metal damping mesh 12, the second bolts 11 are separated from the porous metal damping mesh 12, and then the two second mounting rods 9 are snapped into the mounting groove 2 opened in the aluminum reflector plate 1. Finally, the second bolts 11 and the porous metal damping mesh 12 are locked to complete the installation.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
