Description

Technical Field

[0001] The utility model relates to the technical field of signal antennas, in particular to an explosion-proof signal antenna. Background Art

[0002] In industries like petroleum, chemical processing, gas stations, drilling platforms, coal mines, and dust processing, flammable and explosive gases and dust are present. All communication signals are transmitted via wired connections, requiring extensive cabling and explosion-proof connectors. This results in significant costs and timelines. Harsh operating and operational environments can easily lead to wire failures, causing signal interruptions and impacting the safe operation of networked systems. Adding new equipment to these environments requires shutting down operations, rerouting cables, and ensuring adequate protection, resulting in significant timelines and costs.

[0003] When the signal antenna is in use, first of all, during the installation process, since it is in a shell made of ceramic or other protective structures, its stability during the installation process is poor. In addition, the traditional fixed installation method will, to a certain extent, affect and interfere with the reception and transmission of signals. At the same time, during the installation process, the antenna mounting base is mostly fixedly connected, so the connection wires may become entangled during the installation process, affecting the stability of the antenna connection wires.

[0020] Reference Figure 1-3 An explosion-proof signal antenna includes an antenna housing 1, a mounting base 2 is provided on one side of the antenna housing 1, a movable frame 3 is provided on one side of the mounting base 2, a mounting tube 4 is fixedly connected to one side of the movable frame 3, a connecting wire 6 is provided on one side of the mounting tube 4, a protective tube 5 is fixedly connected to one side of the mounting tube 4, the connecting wire 6 is hung through the protective tube 5, and a movable tube 7 is fixedly connected to one side of the movable frame 3;

[0021] One side of the movable tube 7 is provided with an installation mechanism for installing and supporting the movable frame 3. The installation mechanism includes a limit groove 8 opened on one side of the installation base 2. The side wall of the movable tube 7 is fixedly connected with a plurality of circumferentially arranged limit blocks 9. The limit blocks 9 are slidably connected in the limit groove 8. One side of the limit block 9 is fixedly connected with a connecting block, and the connecting block is slidably connected in the installation base 2.

[0022] A positioning mechanism for supporting and positioning the antenna is provided in the movable tube 7. The positioning mechanism includes a rotating ring 10 arranged on one side of the movable tube 7. A rotating tube 11 is rotatably connected in the rotating ring 10. A plurality of circumferentially arranged fixing frames 12 are fixedly connected to the inner wall of the rotating tube 11. A fitting frame 13 is fixedly connected to one side of the fixing frame 12.
