Description

Technical Field

[0001] This utility model relates to the field of communication technology, and specifically to a cantilever communication antenna. Background Technology

[0002] The installation of communication antennas requires sufficient open space to avoid obstruction. In some specific installation scenarios, the antenna needs to be cantilevered and mounted on one side of a building. In such cases, snow accumulation on the antenna during snowy weather increases its overall weight. This leads to the following problems: 1. Increased antenna weight and cantilever load; 2. Snow accumulation affects signal reception, and the snow is difficult to melt, hindering signal recovery. Therefore, a cantilever communication antenna is urgently needed to solve these problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cantilever communication antenna.

[0004] The cantilever communication antenna of this utility model includes an antenna body and a mounting cantilever for mounting the antenna body. The bottom center of the antenna body is mounted at the end of the mounting cantilever via a connecting unit.

[0005] The connection unit includes a first rotating shaft, a fixed ear, and a movable ear. The fixed ear is located at the end of the mounting cantilever. The first rotating shaft is rotatably mounted inside the fixed ear, perpendicular to the front of the mounting cantilever. The movable ear is fixedly connected to the first rotating shaft and is fixedly mounted at the bottom center of the antenna body.

[0006] It also includes a first driving component, which is used to drive the antenna body to rotate about the first rotating shaft as the rotation axis;

[0007] The mounting cantilever includes a mounting arm and a mounting base. The horizontal distance 'a' between the mounting base and the first rotating shaft is greater than the chord length 'b' of half the arc-shaped cross-section of the antenna body. When the antenna body rotates to the bottom to fit against the mounting arm, the antenna body is in a retracted state.

[0008] In some embodiments, the mounting arm includes a fixing section and a fitting section, the fixing section being fixedly mounted on the mounting base, the fitting section being located on the other side of the fixing section, and the fitting section being inclined downwards as a whole.

[0009] In some embodiments, the device further includes a clamping member and a second driving component for rotating the clamping member. The clamping member is an arc-shaped rod adapted to the curvature of the antenna body. The arc-shaped rod is rotatably connected to a mounting arm or mounting base. When the antenna body is rotated to a retracted state about a first pivot, the arc-shaped rod is clamped against the inner wall of the antenna body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a first rotating shaft to rotate the antenna body to the underside of the mounting cantilever, effectively preventing the antenna body from accumulating snow in severe snowy weather. After the snowfall, the first driving component directly rotates the first rotating shaft to reset the antenna body, thereby restoring normal communication without melting the snow; or by rotating the antenna body, the snow can be dumped, ensuring communication quality during snowy weather while intermittently dumping snow.

[0012] 2. When the antenna body rotates to the retracted state, the center of gravity of the antenna body will move closer to the mounting arm. In the retracted state, the antenna body is less prone to snow accumulation, thereby avoiding excessive load on the mounting arm due to snow accumulation and further increasing the load redundancy of the mounting arm.

[0013] 3. In this utility model, the bonding section is located on the other side of the fixed section, and the bonding section is tilted downwards. After the antenna body is rotated to the retracted state under the drive of the first driving component, the antenna body can be tilted at a large angle, thereby further avoiding snow accumulation. In addition, the snow at the bottom of the antenna body slides off by its own weight when the angle is tilted, further avoiding the increase of the load on the cantilever during heavy snow.

However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential.

[0028] Example 1:

[0029] Please see Figure 1 - Figure 3 The cantilever communication antenna of this utility model includes an antenna body 1 and a mounting cantilever 3 for mounting the antenna body 1. The bottom center of the antenna body 1 is mounted at the end of the mounting cantilever 3 through a connecting unit 2.

[0030] The connecting unit 2 includes a first rotating shaft 21, a fixed ear 22 and a movable ear 23. The fixed ear 22 is located at the end of the mounting cantilever 3. The first rotating shaft 21 is rotatably mounted inside the fixed ear 22, perpendicular to the front of the mounting cantilever 3. The movable ear 23 is fixedly connected to the first rotating shaft 21 and is fixedly mounted at the bottom center of the antenna body 1.

[0031] It also includes a first driving component 5, which is used to drive the antenna body 1 to rotate about the first rotating shaft 21 as the rotation axis;

[0032] The mounting cantilever 3 includes a mounting arm 31 and a mounting base 32. The horizontal distance a between the mounting base 32 and the first rotating shaft 21 is greater than the chord length b of half of the arc cross section of the antenna body 1. When the antenna body 1 rotates to the bottom to fit against the mounting arm 31, the antenna body 1 is in a retracted state.

[0033] In this embodiment:

[0034] The first drive component 5 rotates the first shaft 21, which carries the antenna body 1 to the underside of the mounting cantilever 3. This effectively prevents the antenna body 1 from accumulating snow in severe snowy weather. After the snowfall, the first drive component 5 directly rotates the first shaft 21 to reset the antenna body 1, thus restoring normal communication without melting the snow. Alternatively, rotating the antenna body 1 can clear the snow, ensuring communication quality during snowy weather by intermittently clearing the snow.

[0035] When the antenna body 1 rotates to the retracted state, the center of gravity of the antenna body 1 will move closer to the mounting arm 31. In the retracted state, the antenna body 1 is less likely to accumulate snow, thereby avoiding excessive load on the mounting cantilever 3 due to snow accumulation and further increasing the load redundancy of the mounting cantilever 3.

[0036] Example 2:

[0037] Please see Figure 4 As a further improvement to Embodiment 1: the mounting arm 31 includes a fixing section 311 and a fitting section 312. The fixing section 311 is fixedly mounted on the mounting base 32, and the fitting section 312 is located on the other side of the fixing section 311, and the fitting section 312 is tilted downward as a whole.

[0038] In this embodiment, through further improvements to the mounting cantilever 3, after the antenna body 1 rotates to the retracted state under the drive of the first driving component 5, the antenna body 1 can be tilted at a large angle, thereby further avoiding snow accumulation. Moreover, the snow at the bottom of the antenna body 1 slides off by its own weight when the angle is tilted, further avoiding an increase in the load on the mounting cantilever 3 during heavy snow.

[0039] Example 3

[0040] Please see Figure 5 and Figure 6 As a further improvement to Embodiment 1 or Embodiment 2, it also includes a clamping member and a second driving component 6 for starting the clamping member to rotate. The clamping member is an arc-shaped rod 8 adapted to the curvature of the antenna body 1. The arc-shaped rod 8 is rotatably connected to the mounting arm 31 or the mounting base 32. When the antenna body 1 is rotated to the retracted state around the first rotating shaft 21, the arc-shaped rod 8 is clamped against the inner wall of the antenna body 1.

[0041] In this embodiment, the second driving component 6 can rotate the arc-shaped rod 8 so that it is clamped against the inner wall of the antenna body 1 in its retracted state. This makes the antenna body 1 more stable in its retracted state and more adaptable to extreme weather conditions.

[0042] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made to the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
