[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0028] Technologies, methods, and systems known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0029] Example: Figures 1 to 3The figure is only one of the embodiments of the present invention, an omnidirectionally rotating antenna adjustment frame, comprising an antenna chassis 1 and a supporting chassis 2 arranged at the lower side of the antenna chassis 1, the antenna chassis 1 is provided with an annular groove 11, the supporting chassis 2 is connected to the antenna chassis 1 through a fixing column 21, and the side of the supporting chassis 2 close to the antenna chassis 1 is fixed by a telescopic column 22; the outer side of the fixing column 21 is provided with a planetary gear 211, and the side of the supporting chassis 2 close to the antenna chassis 1 is provided with a telescopic column 22 for connecting with the antenna chassis 1. The sun gear 24 is meshed with the planetary gear 211, and the outer side of the planetary gear 211 is provided with an outer gear ring 23 for meshing with the planetary gear 211. A detection antenna plate 12 is provided on the side of the antenna chassis 1 away from the supporting chassis 2. The detection antenna plate 12 is connected to a driven wheel 122 via a connecting shaft 121, and at least a part of the connecting shaft 121 is located in the annular groove 11. The driven wheel 122 is located on the side of the antenna chassis 1 close to the supporting chassis 2 and meshes with the inner side of the outer gear ring 23.

[0030] During installation, the antenna chassis 1 is connected to the supporting chassis 2 through the fixing column 21, and the antenna chassis 1 and the supporting chassis 2 are arranged in parallel, a planetary gear 211 is arranged on the outside of the fixing column 21, and a sun gear 24 is arranged on the inside of the planetary gear 211 to mesh with each other, and an outer gear ring 23 is arranged on the outside of the planetary gear 211 (the word "outer" in the outer gear ring 23 only means that the outer gear ring 23 itself is arranged on the outside of the planetary gear 211. In fact, the inner side of the outer gear ring 23 is provided with meshing teeth and meshes with the outer side of the planetary gear 211), so that the passive wheel 122 connected to the detection antenna board 12 is also meshed and connected with the meshing teeth on the inner side of the outer gear ring 23; finally, the lower side of the supporting chassis 2 is fixed to the ground or the supporting frame through the telescopic column 22.

[0031] When in use, first extend and retract the multiple telescopic columns 22. In addition to adjusting the height of the antenna chassis 1 and the support chassis 2, the inclination direction of the antenna chassis 1 and the support chassis 2 can also be adjusted according to the different extension amounts of the telescopic columns 22 to complete the preliminary orientation adjustment.

[0032] Then, by driving the sun gear 24 to rotate, the sun gear 24 meshes and drives the planetary gear 211 to rotate, and the planetary gear 211 also meshes and drives the outer ring gear 23 to rotate, so that the passive gear 122 is also meshed and driven to rotate, thereby driving the detection antenna plate 12 to rotate along the extension direction of the annular groove 11 under the limitation of the annular groove 11, thereby completing precise direction adjustment.

[0033] Generally, the annular groove 11 is vertically arranged to adjust the orientation of the detection antenna plate 12 (eg Figure 2In special cases, that is, when the detection accuracy is higher, in order to adjust the direction of the detection antenna plate 12 when it rotates in the annular groove 11, the annular groove 11 is inclined (such as Figure 3 As shown), the accumulation of the angle adjustment of the telescopic column 22 and the angle adjustment of the detection antenna plate 12 rotating in the annular groove 11 is the actual adjustment angle of the detection antenna plate 12, and the two-step adjustment can be completed with higher accuracy.

[0034] Moreover, the sun gear 24 , the outer gear ring 23 and the annular groove 11 are all coaxially arranged.

[0035] Of course, multiple telescopic columns 22 are evenly arranged around the center of the supporting chassis 2, and the number of telescopic columns 22 is at least 3. In this way, it is ensured that the supporting chassis 2 can be tilted in all directions, and at the same time, the antenna chassis 2 can be tilted in all directions. It is best that a universal shaft connector is provided at the connection between the upper end of each telescopic column 22 and the supporting chassis 2 to ensure that the supporting chassis 2 can be tilted while the extension direction of the telescopic column 2 remains unchanged.

[0036] Note that the planetary wheel 211 can only rotate around the central axis of the fixing column 21 , but cannot slide along the extension direction of the fixing column 21 . Here, both ends of the planetary wheel 211 can be limited.

[0037] In this embodiment, the number of the fixed columns 21 and the number of the telescopic columns 22 are at least three. Of course, the specifications of the plurality of planetary gears 211 are the same.

[0038] In this embodiment, the number of the detection antenna board 12 is at least one, and multiple detection antenna boards 12 can be used to perform angle adjustment simultaneously.

[0039] In this embodiment, a driving motor 241 is disposed on a side of the supporting chassis 2 close to the antenna chassis 1 , and the sun gear 24 is connected to the driving motor 241 via a driving shaft 242 . The driving motor 241 is a stepping servo motor.

[0040] In this embodiment, a limiting cylinder for being sleeved on the outer gear ring 23 is provided on a side of the antenna chassis 1 away from the supporting chassis 2, and the outer side wall of the outer gear ring 23 and the inner side wall of the limiting cylinder are both smoothly arranged.

[0041] The omnidirectionally rotating antenna adjustment frame of the present invention has a simple structure and can effectively enable the detection antenna plate to accurately adjust the orientation angle and the position on the antenna chassis. It can also be lifted and lowered, so that it can be adjusted to the optimal detection state during long-distance and high-precision detection work, thereby improving the detection accuracy.

[0042] The present invention is not limited to the above specific implementations, and the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made to the above implementations based on the technical essence of the present invention shall be included in the protection scope of the present invention.
