Problems solved by technology

Because this kind of radome is bulky and has poor dimensional accuracy, it is impossible to ensure that each mounting hole on the side of the radome is coaxially aligned with the mounting holes on the bottom plate
When passing various vibration or high-low temperature shock environmental simulation tests, there is a risk of cracking along the radome installation holes due to the extrusion force of fasteners between holes that cannot be released
Moreover, this kind of packaging structure needs to use fasteners to fix and install each mounting hole of the radome one by one, and it needs to be coated with silica gel to prevent dust and water, which makes the assembly complicated and the production efficiency low

Embodiment 1

[0039] Please refer to the attached Figure 1-3 Embodiment 1 of the present invention proposes a venue antenna 100, which is applied to venues that require large antennas, such as stadiums, etc. Specifically, the antenna 100 includes a sealing and waterproof device and an antenna oscillator (not shown in the figure) , the antenna element is disposed on the reflector assembly 3 . The sealing waterproof device includes:

[0040] Radome 1, foam tape 2 and reflector assembly 3;

[0041] The reflector assembly 3 is provided with folded edges around;

[0042] The radome 1 is sleeved on the outside of the reflector assembly 3;

[0043] One side of the foam tape 2 is pasted on the sides of the reflector assembly 3 by folding and flanging, and the other side is pasted on the side of the inner wall of the radome 1 , so as to realize the sealed connection between the radome 1 and the reflector assembly 3 .

[0044] Specifically, as a preferred solution of the embodiment of the presen...

Embodiment 2

[0047] Please refer to the attached Figure 1-3 , Embodiment 2 of the present invention proposes a venue antenna 100, which is applied to venues that require large antennas, such as stadiums, etc. The structure of Embodiment 2 of the present invention is basically the same as that of Embodiment 1. Specifically, the embodiment of the present invention The difference between the second and the first implementation is:

[0048] In the implementation of the present invention, the sealing and waterproof device also includes an adhesion promoter (not shown in the figure), and before pasting the foam tape 2, the folded edge and the antenna around the reflecting plate assembly 3 to be pasted Apply an adhesion promoter (SIKA PRIMER-215 solvent, for example) to the side of the inner wall of the cover 1, wait for it to dry before pasting the foam tape 2, so as to improve the effect of pasting. Specifically, other adhesion promoters capable of achieving similar functions are also availab...

Embodiment 3

[0053] Please refer to the attached Figure 1-5 Embodiment 3 of the present invention proposes a method for installing a sealing and waterproof device for stadium antenna 100, which can be applied to the installation of the sealing and waterproof device for antenna 100 described in any one of Embodiments 1 and 2 of the present invention. Specifically, the method includes:

[0054] Step S1: Prepare reflector assembly 3, radome 1 and foam tape 2;

[0055] Step S3: Glue the foam tape 2 on the four sides of the reflector assembly 3 by folding and flanging;

[0056] Step S5: Set the radome 1 outside the reflector assembly 3;

[0057] Step S7: Tear off the release paper of the foam tape 2, and press the four sides of the radome 1.

[0058] Specifically, as a preferred solution of the embodiment of the present invention, before the radome 1 is completely sleeved on the reflector assembly 3, a small corner of the release paper of the foam tape 2 should be torn off first, and the re...

Abstract

The invention relates to the technical field of wireless communication equipment, and in particular to a sealing and waterproof device for a stadium antenna, an installation method and the stadium antenna. The sealing and waterproof device includes: a radome, a foam tape, and a reflector assembly; folded edges are provided around the reflector assembly; the radome is sleeved outside the reflector assembly; the foam tape One side is pasted on the side of the folded flange around the reflector assembly, and the other side is pasted on the side of the inner wall of the radome, so as to realize the sealed connection between the radome and the reflector assembly. The present invention adopts the installation structure of viscose foam tape, compared with the traditional structure installed by fasteners, it not only saves the drilling process of the radome and reflector assembly, but also saves the installation of fasteners and the cost of applying silica gel. The packaging process, the assembly operation is simple and convenient, and the labor cost is greatly reduced. Since the periphery of the radome does not need to be fixed by any fasteners, the appearance of the antenna with this packaging structure is more concise and beautiful.

Description

technical field [0001] The invention relates to the technical field of wireless communication equipment, and in particular to a sealing and waterproof device for a stadium antenna, an installation method and the stadium antenna. Background technique [0002] In the coverage of mobile communication networks, for various sports venues with high density of people, large stadium antennas are generally used to solve the problem of large communication traffic. Due to the large size of the stadium antenna, its radome is usually made by blister or hand lay-up process, and mounting holes are processed on the sides of the radome and the bottom plate, and then the radome and the bottom plate are assembled with fasteners, and then The method of applying silicone in between performs waterproof and dustproof sealing. Due to the bulky size and poor dimensional accuracy of this type of radome, it is impossible to ensure that each mounting hole on the side of the radome is coaxially aligned...
