[0036] Please refer to Figures 1 to 3 The present application provides a communication pole 1000 for directional antenna with strong wind resistance, comprising:

[0037] a pole body 1;

[0038] a rotating mounting column 2 rotatably mounted on the top of the pole body 1;

[0039] a frame assembly 3, the frame assembly 3 comprising a base frame 31, four arc-shaped guide bars 32, and two connecting plates 33, the base frame 31 being mounted on the rotating mounting column 2, the four arc-shaped guide bars 32 being respectively mounted on four corners of the base frame 31, the arc-shaped center lines of the four arc-shaped guide bars 32 coinciding, the four arc-shaped guide bars 32 forming a swinging space, and the two connecting plates 33 being mounted on two sides of the base frame 31;

[0040] an antenna assembly 4, the antenna assembly 4 comprising a directional antenna 41 and a frame 42 arranged around the directional antenna 41, the antenna assembly 4 being located in the swinging space, the four corners of the frame 42 being guided by the four arc-shaped guide bars 32, and the middle portions of the two sides of the frame 42 being provided with rotating shafts rotatably connected to the connecting plates 33;

[0041] a driving assembly 5 for driving the rotating shafts to rotate and swing the antenna assembly 4.

[0042] Wherein, the rod body 1 can be made of metal pipe or composite material, and its height is determined according to actual installation requirements. The rotating mounting column 2 is rotatably connected with the rod body 1 through bearings or rotating disc mechanism. The base frame 31 can be a metal frame structure, and the four arc-shaped guide strips 32 are preferably arc-shaped metal strips with the same curvature, and the arc center lines thereof coincide with the antenna oscillation axis. The connecting plates 33 can be steel plates or aluminum alloy plates, which are fixed on both sides of the base frame 31 by bolts or welding. The side frame 42 can be a metal frame, and guide wheels 44 or sliding blocks can be arranged at the four corners thereof to cooperate with the arc-shaped guide strips 32. The rotating shaft can be a stainless steel shaft, which is connected with the connecting plates 33 through bearings. The driving assembly 5 can be a motor cooperating with a gear transmission, or a hydraulic motor cooperating with a connecting rod mechanism, etc.

[0043] Specifically, the arrangement of the arc-shaped guide strips 32 allows the antenna assembly 4 to be always stably guided during oscillation, and the four contact points are dispersedly stressed. The connection of the base frame 31 and the rotating mounting column 2 allows the overall frame assembly 3 to rotate with the rotating mounting column 2, realizing azimuth adjustment. The rotating connection of the side frame 42 and the connecting plates 33 forms a single-axis oscillation structure, which cooperates with the guiding effect of the arc-shaped guide strips 32 to form a stable two-degree-of-freedom adjustment mechanism. The driving assembly 5 can realize accurate positioning of the antenna assembly 4 in the oscillation space by accurately controlling the rotating angle of the rotating shaft.

[0044] The technical scheme solves the problem of easy damage of the traditional single-point hinged structure under strong wind conditions through the cooperation of the frame assembly 3 and the antenna assembly 4. The guiding structure formed by the four arc-shaped guide strips 32 disperses the wind load to multiple support points, greatly reducing the stress of a single connection point. At the same time, the design of the oscillation space limits the oscillation amplitude of the antenna assembly 4, avoiding structural damage caused by excessive oscillation. Compared with the prior art, the structure has higher stability and wind resistance, and can ensure the normal work of the directional antenna 41 under severe weather conditions.

[0045] Please refer to Figure 1 and Figure 2 , further, a guide groove 321 is formed in the inner side of the arc-shaped guide strip 32, and a guide device is arranged at the four corners of the side frame 42, which comprises:

[0046] A connecting block 43 connected with the side frame 42;

[0047] A guide wheel 44 installed on the connecting block 43, which extends into the guide groove 321.

[0048] Specifically, the guide groove 321 is a groove structure extending along the length direction of the arc-shaped guide strip 32, and the cross-sectional shape thereof can be U-shaped, V-shaped or semicircular. The guide wheel 44 is made of wear-resistant material, such as nylon or polyurethane, and has a diameter slightly smaller than the width of the guide groove 321 to ensure smooth rolling. The connecting block 43 is fixed to the four corners of the frame 42 by bolts or welding, and the contact surface thereof with the frame 42 can be provided with a buffer gasket to reduce vibration transmission. The guide wheel 44 is mounted on the connecting block 43 through a bearing, and the type of the bearing can be selected as a deep groove ball bearing or a self-lubricating bearing. The inner wall of the guide groove 321 can be coated with a low-friction material, such as a Teflon coating, to reduce the movement resistance of the guide wheel 44.

[0049] Thus, the technical scheme converts the swinging movement of the antenna assembly 4 into the rolling movement of the guide wheel 44 along the guide groove 321 through the cooperation of the guide groove 321 and the guide wheel 44, effectively disperses the concentrated stress of the hinge point caused by the wind load. The guide device works at four corners at the same time, forming a stable four-point support structure, avoiding the problem of easy damage of single-point hinge. The rolling friction significantly reduces the movement resistance compared with sliding friction. The close cooperation of the guide wheel 44 and the guide groove 321 also plays a limiting role, preventing the antenna assembly 4 from producing excessive deflection in strong wind. The sealing structure further protects the internal components of the guide device from the external environment, prolonging the service life.

[0050] Please refer to Figure 1 and Figure 2 , further, one side of the connecting block 43 is provided with a sealing structure for sealing the cooperation gap between the guide wheel 44 and the guide groove 321.

[0051] The technical scheme sets the sealing structure to prevent rainwater, dust and other external pollutants from entering the cooperation gap between the guide wheel 44 and the guide groove 321. The movement of the guide wheel 44 in the guide groove 321 is not affected by the external environment, avoiding the problem of jamming caused by the accumulation of pollutants. Compared with the prior art, the sealing structure significantly improves the environmental adaptability and service life of the moving parts while maintaining the guiding accuracy.

[0052] Please refer to Figure 1 and Figure 2 , further, the sealing structure includes a sealing ring 45 and two sealing sheets 46, the sealing ring 45 abuts against the arc-shaped guide strip 32, and the two sealing sheets 46 are located on both sides of the guide wheel 44, and the sealing sheet 46 extends into the guide groove 321. The sealing structure further includes a sealing strip 47, which is attached to the top surface of the arc-shaped guide strip 32 and covers the guide groove 321.

[0053] The sealing ring 45 is made of elastic material and can tightly fit the outer surface of the arc-shaped guide strip 32 to prevent external dust and moisture from entering the guide groove 321. The sealing sheet 46 is made of wear-resistant rubber material and has a thickness slightly smaller than the width of the guide groove 321, which ensures smooth sliding of the guide wheel 44 in the guide groove 321 while blocking impurities from entering. The sealing strip 47 has a long arc-shaped structure and is arranged to fit the top edge of the arc-shaped guide strip 32 to completely cover the opening of the guide groove 321. As a preferred embodiment, the sealing sheets 46 on both sides of the guide wheel 44 can be symmetrically installed, and the edges of the sheets are provided with bent portions to enhance the structural strength.

[0054] The technical scheme effectively solves the problem of dust and water prevention of the guide device in an outdoor environment through a multi-layer sealing design. The sealing ring 45 tightly contacts the arc-shaped guide strip 32 to form the first barrier, which blocks most external pollutants. The sealing sheets 46 on both sides continuously scrape off impurities attached to the surface of the guide wheel 44 during the movement of the guide wheel 44. The sealing strip 47 on the top completely isolates the vertical penetration of rainwater. Compared with the traditional scheme of a single sealing member, this composite sealing structure significantly improves the reliability of the guide device in severe weather conditions and prolongs the service life of the moving parts. Specifically, the bilateral arrangement of the sealing sheets 46 avoids the sealing failure caused by unilateral wear, and the covering installation of the sealing strip 47 compensates for the protective defects of the open design at the top of the guide groove 321.

[0055] Please refer to Figure 1 and Figure 2 Further, the frame assembly 3 further comprises four inner guide strips 34, the inner guide strips 34 are connected with the arc-shaped guide strips 32, and arc-shaped grooves are formed in the side portions of the frame 42 to be clamped into the inner guide strips 34 to assist in guiding the antenna assembly 4.

[0056] The technical scheme adds the inner guide strips 34 in the frame assembly 3 to form a double guide structure with the arc-shaped grooves in the side portions of the frame 42. When the wind acts on the antenna assembly 4, the arc-shaped guide strips 32 and the guide wheel 44 cooperate to provide the main guiding function, and the inner guide strips 34 and the arc-shaped grooves cooperate to form auxiliary guiding, effectively dispersing the single-point stress. Specifically, the inner guide strips 34 can bear part of the lateral load to reduce the load of the guide wheel 44, thereby reducing the wear of the guide device. Compared with the prior art, the structure significantly improves the stability of the antenna assembly 4 in strong wind conditions, and prolongs the service life of the guide mechanism by dispersing the stress points.

[0057] Please refer to Figure 1 and Figure 2 Further, the two ends of the inner guide strips 34 and the two ends of the arc-shaped guide strips 32 are connected by connecting strips.

[0058] The connection strip is arranged to connect the inner guide strip 34 and the two ends of the arc-shaped guide strip 32, which can effectively enhance the overall structural strength of the frame assembly 3. Specifically, as a transverse connecting piece, the connection strip can constrain the relative displacement between the inner guide strip 34 and the arc-shaped guide strip 32, preventing deformation or breakage under the action of wind load. At the same time, this connection mode forms a closed loop frame for the guide structure, improving the guide stability during the swinging process of the antenna assembly 4. Compared with the single-point hinged structure, the technical solution disperses the wind load stress through the multi-point connection mode, reduces the risk of local stress concentration, and thus prolongs the service life of the guide mechanism.

[0059] Please refer to Figure 1 and Figure 2 Further, the width of the arc-shaped slot is greater than the thickness of the arc-shaped guide strip 32.

[0060] Specifically, the arc-shaped slot is arranged on the side of the frame 42 and is used to clamp the inner guide strip 34 to achieve an auxiliary guiding function. The slot width is designed to be greater than the thickness of the arc-shaped guide strip 32, thereby providing a suitable movement gap for the frame 42 during swinging. As a preferred embodiment, the slot width can be controlled within the range of 0.5-2mm greater than the thickness of the arc-shaped guide strip 32, for example, a 1mm gap design can ensure guiding accuracy and avoid jamming due to thermal expansion and contraction or manufacturing errors. The gap allows the frame 42 to produce a small deflection when subjected to wind force, thereby reducing the load on the single hinge point by dispersing the stress.

[0061] The technical solution solves the stress concentration problem caused by rigid connection in the prior art by precisely controlling the fitting tolerance of the guide structure. When the directional antenna 41 is subjected to lateral wind force, the frame 42 can produce a small amount of displacement along the inner guide strip 34, so that the wind load is shared by the four arc-shaped guide strips 32 and the inner guide strip 34, thereby significantly reducing the torsional moment at the hinge of the rotating shaft. Compared with the existing single-point hinged structure, the design effectively prolongs the service life of the driving assembly 5 and the sealing structure, while maintaining the stability during the swinging process of the antenna.

[0062] Please refer to Figure 1 to 3 Further, the driving assembly 5 comprises:

[0063] The large gear 51 is arranged on the rotating shaft;

[0064] The reduction motor 52 is located on one side of the directional antenna 41;

[0065] The connecting shaft 53 is connected to the rotating shaft of the reduction motor 52;

[0066] The small gear 54 is fixed to the end of the connecting shaft 53 and is engaged with the large gear 51.

[0067] The driving assembly 5 further comprises a housing 55, both ends of which are fixed to the connecting plate 33, and the inside of the housing 55 is a closed space, and the large gear 51, the reduction motor 52, the connecting shaft 53 and the small gear 54 are all located in the closed space.

[0068] Specifically, the large gear 51 is fixedly connected with the rotating shaft, and the power of the reduction motor 52 is transmitted to the rotating shaft through gear transmission. The reduction motor 52 can be a stepper motor or a servo motor to realize accurate angle control. The connecting shaft 53 can be a rigid coupling or a universal joint coupling to adapt to the needs of different installation positions. The gear ratio of the small gear 54 and the large gear 51 can be adjusted according to the required reduction ratio. The housing 55 can be made of metal or engineering plastic, and a sealing ring or sealing glue is arranged inside to ensure the airtightness. Both ends of the housing 55 are fixed on the connecting plate 33 by bolts or welding.

[0069] For this, the technical scheme realizes the swing control of the directional antenna 41 through gear transmission, and the closed housing 55 structure can effectively protect the internal transmission components from the influence of the external environment. The reduction motor 52 cooperates with the gear set to provide sufficient torque to overcome the wind resistance, while realizing accurate angle adjustment. The closed design of the housing 55 prevents rainwater and dust from entering the transmission system, prolonging the service life of the driving assembly 5. Compared with the prior art, the scheme solves the problem that the single-point hinged structure is easily damaged in harsh environments, and improves the reliability and stability of the system through the multi-point fixed housing 55 structure and the gear transmission method.

[0070] The above only describes the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
