DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Specific implementation examples Figure 1 、 Figure 3 As shown, this embodiment relates to an antenna attitude adaptive adjustment device, in which the antenna 1 is mounted on a fixing frame 2 with the aid of the adjustment device. One end of the antenna 1 is hinged to the fixing frame 2 to form a first hinge axis 3. The other end of the antenna 1 is provided with a pitch angle adjustment unit, which includes a first telescopic rod 4. The first telescopic rod 4 is hinged between the fixing frame 2 and the antenna 1. The antenna 1 has the freedom to pitch and swing around the first hinge axis 3 by virtue of the extension and contraction of the first telescopic rod 4.

[0024] In this embodiment, the first hinge shaft 3 is provided at the lower portion of the antenna 1 , and the first telescopic rod 4 is hinged to the upper portion of the antenna 1 .

[0025] When the pitch angle needs to be adjusted, the length of the first telescopic rod 4 is controlled to change, so that the antenna 1 can be rotated around the first hinge axis 3. The pitch adjustment unit has a simple structure and is easy to control, without manual climbing operations.

[0026] Furthermore, the fixing frame 2 is provided with a first mounting block 5, a second mounting block 13, and an azimuth adjustment unit. The fixing frame 2 is hinged to the first mounting block 5 to form a second hinge axis 6, and to the second mounting block 13 to form a third hinge axis 14. The axes of the second hinge axis 6 and the third hinge axis 4 are arranged collinearly, and the second hinge axis 6 is arranged perpendicular to the first hinge axis 3. The antenna 1 is hinged to the second mounting block 13 to form the first hinge axis 3. The first telescopic rod 4 is hinged between the first mounting block 5 and the antenna 1. The first mounting block 5 and the second mounting block 13 have the freedom to swing horizontally about the third hinge axis 14 by means of the azimuth adjustment unit. Specifically, the first mounting block 5 is located at a high position and is hinged to the first telescopic rod 4. The second mounting block 13 on the fixing frame 2 is located at a low position and is hinged to the antenna 1 to form the first hinge axis 3. The azimuth angle adjustment unit works to make the first mounting block 5 and the second mounting block 13 swing around the third hinge shaft 14 , and the first mounting block 5 and the second mounting block 13 drive the antenna 1 to swing around the third hinge shaft 14 to adjust the azimuth angle of the antenna 1 .

[0027] like Figure 4As shown, the azimuth adjustment unit includes a second telescopic rod 7, whose ends are hinged to the fixing frame 2 and the second mounting block 13, respectively. Extension or contraction of the second telescopic rod 7 creates a push-pull effect on the second mounting block 13, causing it to rotate about a third hinge axis 14. This second mounting block 13 then drives the antenna 1 and the first mounting block 5 to rotate about the third hinge axis 14. This azimuth adjustment unit has a simple structure and is easy to control. The antenna azimuth angle can be adjusted simply by changing the length of the second telescopic rod 7. The first and second telescopic rods 4 and 7 are electrically operated.

[0028] Furthermore, the pitch angle adjustment unit also includes an auxiliary pitch device, such as Figure 2 As shown, the auxiliary pitch device cover is buckled above the first telescopic rod 4. The auxiliary pitch device includes a first cover plate 8 and a second cover plate 9. The antenna 1, the first cover plate 8, the second cover plate 9, and the first mounting block 5 on the mounting bracket 2 are hingedly connected in sequence. The provision of the auxiliary pitch device improves the connection stability between the antenna 1 and the mounting bracket 2 and also makes the angle adjustment process of the antenna 1 more stable when the length of the first telescopic rod 4 changes. Furthermore, the auxiliary pitch device cover buckled above the first telescopic rod 4 forms a protective cover for the first telescopic rod 4, reducing direct contact between rain, dust, etc. and the first telescopic rod 4, thereby helping to increase the service life of the first telescopic rod 4.

[0029] Further, such as Figure 3 、 Figure 5 As shown, the first telescopic rod 4 is mounted on the fixed frame 2 via a first connecting plate 10. The fixed end 1001 of the first connecting plate 10 is bolted to the fixed frame 2, and the overhanging end 1002 of the first connecting plate 10 is hingedly connected to the first telescopic rod 4. Specifically, the first connecting plate 10 is located below the first mounting block 5 and has an L-shaped structure, with the fixed end 1001 vertically positioned and the overhanging end 1002 horizontally positioned. The fixed end 1001 is securely connected to the first mounting block 5 via bolts. The simple structure of the first connecting plate 10 facilitates installation, and without changing the overall dimensions of the first mounting block 5, the structures of the first mounting block 5 and the second mounting block 13 remain essentially identical, making it easy to manufacture and quickly install.

[0030] Further, such as Figure 3 、 Figure 6As shown, the first telescopic rod 4 is hingedly connected to the antenna 1 via a second connecting plate 12. The antenna 1 is fixedly connected to a hinged rod 11. The first cover plate 8 is hingedly connected to the antenna 1 via the hinged connection to the hinged rod 11. The second connecting plate 12 includes a main plate 1201 and a snap-fit ​​plate 1202. The fixed end of the main plate 1201 and the end of the snap-fit ​​plate 1202 form a semi-circular ring structure. The snap-fit ​​plate 1202 is connected to the main plate 1201 via bolts. The fixed end of the main plate 1201 and the end of the snap-fit ​​plate 1202 snap together to form a circular ring fixedly connected to the hinged rod 11. The first telescopic rod 4 is hingedly connected to the overhanging end of the main plate 1201. During installation, the fixed end of the main plate 1201 and the end of the snap-fit ​​plate 1202 are snapped onto the hinged rod 11, and then bolted through the main plate 1201 and the snap-fit ​​plate 1202 to tighten. The antenna 1 can be installed on its original structure, resulting in a simple structure and convenient installation.

[0031] The utility model realizes automatic adjustment of the antenna angle by means of the pitch angle adjustment unit and the azimuth angle adjustment unit, and has a stable and reliable structure, does not require manual high-altitude operation, has a high operational safety factor, and the antenna angle is easy to change and control.
