[0029] The preferred embodiments of the utility model will be described in detail below with reference to the drawings, wherein the drawings constitute a part of the utility model, and are used together with the embodiments of the utility model to explain the principles of the utility model, and are not used to limit the scope of the utility model.

[0030] As Figure 1 shown, the antenna array pitching and rotating device of the embodiment, comprising antenna mounting part 1, rotating part 2, rotating shaft 3, supporting part 4 and electric rotary base 5. Line mounting part 1 is used to fix and install antenna equipment, and the antenna mounting part 1 can be quickly detachably connected with the rotating part 2, the rotating part 2 is rotatably connected with the top end of the supporting part 4 through the rotating shaft 3, realizing manual pitching of the antenna device; the bottom end of the supporting part 4 is fixed on the electric rotary base 5, realizing electric rotation of the antenna device.

[0031] In the actual use process of the antenna array pitching and rotating device, the pitching direction usually requires-30°-90° range coverage, and in the horizontal direction, it requires 360° coverage; considering that the angle does not need to be adjusted frequently during pitching, and the antenna has 30° in the pitching direction and horizontal direction, and has radio frequency signal transmission, a slip ring cannot be used. According to the use requirement, the embodiment adopts one-dimensional non-continuous rotating electric rotary base 5 in the horizontal position, which can continuously rotate in ±175° range, and through the manual pitching mechanism, the pitching angle of-15°-75° in the pitching position can be realized. The antenna array pitching and rotating device of the embodiment is light in weight, good in portability, can realize quick disassembly and erection, and has good stability.

[0032] AsFigure 2 As shown, the antenna mounting component 1 includes a mounting part 11, a lug 12, a hanging shaft 13, and a tenon 14. The antenna mounting component 1 is made of high-strength alloy. The mounting part 11 is a flat plate structure with mounting screw holes symmetrically arranged on the plate. One side of the mounting part 11 is fixedly connected to the antenna equipment by screws.

[0033] On the other side of the mounting part 11, there is a lug 12. Preferably, there are two pairs of lugs 12, which are respectively arranged on both sides of the upper end of the mounting part 11. Both pairs of lugs 12 are parallel to and symmetrically arranged with respect to the plane of symmetry of the mounting part 11. The lugs 12 are provided with through holes, and the center lines of each through hole coincide. A hanging shaft 13 is provided in the through hole of each pair of lugs 12. The space between the two hanging shafts 13 and the mounting part 11 forms two mortise and tenon joints 14 for quick matching and disassembly with the rotating part 2.

[0034] like Figure 3 As shown, the rotating component 2 is a flat plate-shaped part, including a tenon 21, a limiting part 22, and a rotating shaft mounting hole. The tenon 21 and the limiting part 22 are located on one side of the rotating component 2 and are used to connect with the antenna mounting component 1. The tenon 21 matches the mortise 14, allowing the antenna mounting component 1 to hang on the rotating component 2. The limiting part 22 is connected to the root of the tenon 21 and is used to limit the other end of the mounting part 11. The rotating shaft mounting hole is located on the other side of the rotating component 2 and is used to fix it to the rotating shaft 3. Preferably, there are two rotating components 2, which are respectively fixed to both ends of the rotating shaft 3.

[0035] Specifically, the tenon 21 includes a shoulder 211 and a tongue 212. The shoulder 211 is located on the side of the tenon 21 near the pivot mounting hole. When the tenon 21 is inserted into the mortise 14, the hanging shaft 13 can fall on the shoulder 211, so that the antenna mounting part 1 is hung on the rotating part 2 under the action of gravity.

[0036] Preferably, the tenon shoulder 211 has an arc-shaped cylindrical surface that matches the surface of the hanging shaft 13. This allows the hanging shaft 13 to be quickly and stably positioned in contact with the arc-shaped cylindrical surface when the antenna mounting component 1 is hung on the tenon shoulder 211. At the same time, it increases the contact area between the hanging shaft 3 and the tenon shoulder 211, avoiding the concentration of forces between them and preventing damage to the components.

[0037] In order to enable the tenon 21 to be quickly and smoothly inserted into the mortise 14, the width of the end of the tenon tongue 212 is smaller than the width of the root. This allows the end of the tenon tongue 212 to be easily inserted into the mortise 14, and also allows the root of the tenon tongue 212 to be engaged with the mortise 14.

[0038] Preferably, the tongue 212 is hook-shaped, on one hand, the outer surface of the connection between the tongue 212 and the limiting part 22 has an arc surface, which can buffer the fitting process of the mounting part 11 and the limiting part 22 when the antenna mounting piece 1 is quickly hung on the rotating piece 2; on the other hand, the side of the tongue 212 connected with the tenon shoulder 211 is inclined to the rotating shaft 3 direction, so that when the antenna mounting piece 1 is at each pitch angle, the tenon 21 can stably hook the hanging shaft 13, thereby making the pitch angle of the antenna array more stable and accurate.

[0039] Preferably, in order to reduce the friction force when the tenon 21 is inserted into the mortise 14, the hanging shaft 13 is rotatably connected between the lug 12. As shown in the figure, the hanging shaft 13 is provided with a shaft cap and an annular clamping groove at the other end, and the two ends of the hanging shaft 13 are rotatably connected with a pair of lugs 12 through the installation of a clamping ring. Figure 3

[0040] Preferably, in order to make the antenna mounting piece 1 more accurately and quickly installed on the rotating piece 2, the antenna mounting piece 1 is also provided with a guide part 15, which is located on both sides of the antenna mounting piece 1 and connected with the two outer lugs 12. The inner surfaces of the two guide parts 15 are coplanar with the inner surfaces of the two outer lugs 12, so that the antenna mounting piece 1 can be hung on the rotating piece 2, and the tenon 21 and the limiting part 22 can be guided and positioned.

[0041] In order to fix the antenna mounting piece 1 on the rotating piece 2, the antenna mounting piece 1 and the rotating piece 2 are correspondingly provided with locking screw holes for fixing the antenna mounting piece 1 and the rotating piece 2 through the locking screw 25. Preferably, the locking screw holes are respectively located at the ends of the guide part 15 and the limiting part 22, so that the antenna mounting piece 1 is tightly assembled with the rotating piece 2 at the four vertices.

[0042] Further, the rotating piece 2 is also provided with a locking groove 23, which is an arc-shaped through groove arranged around the rotating shaft 3, and is used for fixing and locking the rotating piece 2 and the support 4 through the bolt assembly 26 to maintain the required pitch angle.

[0043] In order to make the rotating piece 2 more firmly locked on the support 4, preferably, the periphery of the locking groove 23 is provided with a boss, which is polished. Preferably, the bolt assembly 26 adopts a locking nut to improve the locking effect of the rotating piece 2 on the support 4.

[0044] Preferably, the rotating piece 2 also includes a dial 24, which is arranged around the rotating shaft 3 and is used for setting the pitch angle of the rotating piece 2. Optionally, the locking groove 23 is arranged on two rotating pieces 2 respectively to facilitate operation and observation.

[0045] ​Further, the two ends of the rotating shaft 3 are rotatably connected with the support 4 through inlaid titanium alloy shaft sleeves, and a closed cavity is formed between the rotating shaft 3 and the support 4 through grease filling.

[0046] As shown in Figure 1 , the support 4 is made of aluminum alloy casting processing, and the whole adopts an inclined design, which can meet the large-angle pitching requirement, greatly reduce the eccentric moment caused by the gravity center deviation, and reduce the load of the bottom motor. The bottom of the support 4 is connected with the electric rotating base through a rotary bearing. The electric rotating base is provided with a power module, a control module and a motor assembly. The brake motor has a self-locking function, is reduced through a two-stage speed reduction mechanism, and is then output by the rotary bearing, so that the load rotates. In addition to the soft limit of the motor, the electric rotating base is also provided with a hard limit stopper, which can make the motor stop and lock through current overload.

[0047] Taking one specific design scheme of the embodiment as an example: the self-weight of the pitching and rotating device is 9 kg, the designed load is 25 kg, the load windward area is designed as 0.6 m2, and the non-destructive wind speed is 30 m / s. The overall weight of the support 4 is about 986 g, the support height is 200 mm, and the center of the rotating shaft 3 is 50 mm away from the electric rotating base. The design scheme has the following advantages:

[0048] 1. The overall weight is low, and the equipment weight is only 9 kg, which basically has good portability;

[0049] 2. The disassembly and erection are convenient, and a single person can operate, and the disassembly and erection time is less than 1 minute, which only needs to operate two locking screws;

[0050] 3. Good stability, strong wind resistance and torsion resistance, and small load gravity center deviation during pitching, which is very beneficial for portable erection, such as triangular support erection;

[0051] 4. Strong adaptability, the movable parts are made of titanium alloy material, and the corrosion resistance effect is very good, which can be erected in an open place at will;

[0052] 5. Low power consumption, the rated power consumption of the whole machine is less than 40 W, which is suitable for outdoor erection;

[0053] 6. Small size, which can greatly reduce the space behind the antenna array surface.

[0054] Figure 4 For the case of erecting the antenna array surface by 15°, Figure 5For the case of erecting the antenna array surface at 75°, the antenna array surface has a size of 1000mm*600mm*300mm, and by adjusting the position of the power amplifier of the antenna array surface, the load center of gravity 100 of the antenna array surface can be made close to the rotation center 200. By comparing the erection results, it can be seen that the load center of gravity 100 fluctuates less, and when erecting at 15°, the distance from the rotation base center line is 44mm, and when erecting at 75°, the distance from the rotation base center line is 20mm, and the center of gravity deviation condition is greatly improved.

[0055] The above merely describes a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
