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 stadium antenna 100, which is applied to a stadium that needs to use a large antenna, such as a stadium, etc. Specifically, the antenna 100 includes a sealed waterproof device and an antenna vibrator (not shown in the figure) , the antenna element is arranged on the reflector assembly 3 . The sealing and waterproofing device includes:

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

[0041] The reflective plate assembly 3 is provided with folding edges around it;

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

[0043] One side of the foam tape 2 is pasted on the side of the folded edge around the reflector assembly 3 , 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...

Embodiment 2

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

[0048] In the implementation of the present invention, the sealing and waterproofing device further includes an adhesion promoter (not shown in the figure), and before pasting the foam tape 2, first place the folded edges around the reflector assembly 3 to be pasted and the antenna Apply an adhesion promoter (for example, SIKA PRIMER-215 solvent) to the side of the inner wall of the cover 1, and wait for it to dry before sticking the foam tape 2, so as to improve the sticking effect. Specifically, other adhesion promote...

Embodiment 3

[0053] Please refer to the attached Figure 1-5 , the third embodiment of the present invention proposes a method for installing a sealed waterproof device for a stadium antenna 100, which can be applied to the installation of the sealed waterproof device for the antenna 100 according to any one of the first and second embodiments of the present invention, Specifically, the method includes:

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

[0055] Step S3: Flip and stick the foam tape 2 around the reflector assembly 3;

[0056] Step S5: sleeve the radome 1 on the outside of the reflector assembly 3;

[0057] Step S7 : tear off the isolation paper of the foam tape 2 , and press around 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, the release paper of the foam tape 2 should be torn off a small corner, and the r...

Abstract

The invention relates to the technical field of wireless communication equipment, particularly to a sealing waterproof device of a venue antenna, an installation method and the venue antenna. The sealing waterproof device comprises an antenna cover, a foam adhesive tape and a reflecting plate assembly, wherein the periphery of the reflecting plate assembly is provided with folded edges, the antenna cover is arranged outside the reflecting plate assembly in a sleeving manner, one surface of the foam adhesive tape is pasted on the side surface of the folded edges on the periphery of the reflecting plate assembly, and the other surface of the foam adhesive tape is pasted on the side surface of the inner wall of the antenna cover so as to realize the sealing connection between the antenna cover and the reflecting plate assembly. Compared with a traditional structure that installation is conducted through a fastener, the installation structure of the foam adhesive tape is adopted, so that the drilling procedure of the antenna housing and the reflection plate assembly is omitted, the installation procedure of the fastener and the packaging procedure of silica gel smearing are also omitted, assembly operation is easy and convenient, and the labor cost is greatly reduced; and the periphery of the antenna cover does not need to be fixed by any fastener, so that the appearance of the antenna with the packaging structure is simpler and more attractive.

Description

technical field [0001] The present 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 a stadium antenna. Background technique [0002] In the coverage of the mobile communication network, large-scale stadium antennas are generally used for various sports venues with high density of people to solve the problem of large communication traffic. Due to the large size of the stadium antenna, the radome is usually made of plastic or hand lay-up, and mounting holes are processed on the surrounding sides of the radome and the bottom plate, and then the radome and the bottom plate are assembled with fasteners, and then the The method of smearing silicone between the two is used for waterproof and dustproof packaging. Since such a radome is bulky and has poor dimensional accuracy, it cannot be ensured that each mounting hole on the side of the radome is co...
