Description

Technical Field

[0001] The present invention relates to the technical field of drone base stations, and specifically to a drone base station antenna maintenance device. Background Art

[0002] Drone base station antennas are core components of drone communication systems, primarily used to establish wireless data links between drones and ground control stations. These antennas typically utilize a multi-band array design and are mounted on the top or side of the base station. Their performance directly impacts the drone's communication range, image transmission quality, and flight control stability. In challenging operating environments like deserts and Gobi deserts, base station antennas are exposed to windy and sandy conditions for extended periods, posing significant challenges to their structural strength and signal transmission quality.

[0003] Existing technologies for maintaining drone base station antennas have significant shortcomings, particularly in terms of wind and sand protection. Traditional base stations often utilize fixed metal shields. While this design can partially block wind and sand, it suffers from three major drawbacks: First, the shield cannot dynamically adjust its protection based on wind and sand intensity, resulting in surface wear and structural deformation of the antenna during strong winds and sandstorms. Second, the fixed structure hinders routine maintenance and height adjustment of the antenna, affecting its compatibility with different drone models. Therefore, a drone base station antenna maintenance device is proposed to address these issues. Summary of the Invention

[0004] In order to solve the above-mentioned problems, the present invention provides a UAV base station antenna maintenance device to solve the above-mentioned problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A drone base station antenna maintenance device includes a drone base station body, which includes four drone antennas. An external support frame is installed at the bottom of the drone base station body, and wind and sand shielding components are installed on both sides of the external support frame to block wind and sand and maintain the drone antennas. Auxiliary support parts are also provided on both sides of the drone base station body to assist in tightening the wind and sand shielding components.

[0007] Furthermore, the main body of the drone base station also includes a base station floor and multiple corner snap-in frames. The four drone antennas are respectively installed on the four corners of the base station floor. The side of the base station floor is snap-in with multiple side support frames, and the adjacent side support frames are fixed by snap-in frames.

[0008] Furthermore, connection blocks are inserted into the plurality of corner snap-fit ​​frames, and the other ends of the plurality of connection blocks are snap-fitted with the adjacent side support frames.

[0009] Furthermore, the external support frame includes two transverse support rods, a connecting skeleton is installed between the two transverse support rods, and the transverse support rods and the connecting skeleton are both fixed to the bottom of the drone base station body.

[0010] Furthermore, the wind and sand shield assembly includes two first servo motors and two support rings, the two support rings are fixed to the transverse support rod, the output shafts of the two first servo motors are connected to the first threaded rotating rods through couplings, the top ends of the two first threaded rotating rods pass through and extend from the transverse support rod, the two first threaded rotating rods are threadedly connected to threaded lifting connecting blocks, and the wind and sand shield curtain is connected between the two threaded lifting connecting blocks;

[0011] Wherein, two longitudinal support rods are installed on each of the two transverse support rods, and the plurality of threaded lifting connection blocks are all slidably connected to the adjacent longitudinal support rods.

[0012] Furthermore, the two first threaded rotating rods are both rotatably connected to the support ring, and the wind and sand shielding curtains are both connected to adjacent support rings.

[0013] Furthermore, a connecting base is installed at the bottom of each of the four first servo motors.

[0014] Furthermore, the auxiliary support member includes a second threaded rotating rod and a second servo motor, the second threaded rotating rod is threadedly connected to a threaded positioning ring, the threaded positioning ring is fixed to the bottom of the drone base station body, a driving gear ring is installed on the threaded positioning ring, the second servo motor is installed with a driving gear, the driving gear is engaged with the adjacent driving gear ring, one end of the second threaded rotating rod is connected to a propulsion plate, and the propulsion plate is located between the adjacent wind and sand shielding assembly and the drone base station body.

[0015] Furthermore, an auxiliary support block is installed on the top of the propulsion plate, and auxiliary rubber rods are hinged at both ends of the auxiliary support block, and the two auxiliary rubber rods are rotatably connected to the wind and sand shielding assembly.

[0016] Furthermore, a limiting slider is installed on one end of the second threaded rotating rod away from the propulsion plate, and the limiting slider is slidably connected to the bottom of the drone base station body.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This drone base station antenna maintenance device significantly improves the device's protection and operational stability in windy and sandy environments through multiple structural innovations. First, the collaborative design of the external support frame and the wind and sand shielding assembly forms the core protection system. The external support frame forms a stable base support through transverse support rods and a connecting skeleton, which elevates the base station as a whole and effectively isolates ground dust. The wind and sand shielding curtain utilizes a multi-layer composite material (Oxford cloth + soft steel wire) structure. Driven by a servo motor, it is raised and lowered via threaded rotating rods, forming a protective barrier when deployed. A precision transmission system consisting of threaded lifting connecting blocks and longitudinal support rods ensures smooth curtain raising and lowering. The auxiliary support's propulsion plate cooperates with the drive gear to tighten the curtain through propulsion pressure in strong winds. Combined with the deformation buffering of the auxiliary rubber rod, this creates a dynamically reinforced protective structure. The device also uses a dual positioning mechanism, including a support ring and a limit slider, to ensure the mechanical stability of the assembly in extreme environments. The overall protection system reduces the risk of antenna breakage.

[0019] Secondly, a modular design concept permeates the entire device architecture, significantly improving environmental adaptability and ease of maintenance. The base station body utilizes a modular assembly structure consisting of layered side support frames and corner snap-on frames. Connecting these blocks allows for different height combinations, allowing the take-off and landing platform to be flexibly adjusted to suit the type of drone. The longitudinal support rods on the external support frame and the connecting frame form a triangular stabilization mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Reference Figure 1-5 A drone base station antenna maintenance device includes a drone base station body 1, which includes four drone antennas 12. An external support frame 2 is installed at the bottom of the drone base station body 1, and wind and sand shielding components 3 are installed on both sides of the external support frame 2 to block wind and sand and maintain the drone antenna 12. Auxiliary support parts 4 are also provided on both sides of the drone base station body 1 to assist in tightening the wind and sand shielding components 3.

[0029] Specifically, the device adds an external support frame 2 to the bottom of the drone base station body 1 to lift the entire drone base station body 1, while adding a wind and sand shielding component 3 to achieve effective wind and sand protection for the drone base station body 1 and the multiple drone antennas 12 inside the drone base station body 1, preventing wind and sand from directly invading the drone base station body 1, breaking the drone antenna 12 or eroding the surface of the drone antenna 12, causing damage to the drone antenna 12. The addition of auxiliary support parts 4 can further assist the wind and sand shielding component 3 and increase the wind and sand resistance of the wind and sand shielding component 3.

[0030] As an optimization solution, Figure 1-5As shown, the drone base station body 1 also includes a base station floor 11 and multiple corner snap-fit ​​frames 14. Four drone antennas 12 are respectively installed on the four corners of the base station floor 11. The side of the base station floor 11 is snap-fitted with multiple side support frames 13. The adjacent two side support frames 13 are snap-fitted and fixed by the corner snap-fit ​​frames 14. Connecting blocks 15 are inserted into the multiple corner snap-fit ​​frames 14, and the other ends of the multiple connecting blocks 15 are snap-fitted with the adjacent side support frames 13.

[0031] Specifically, in the main body 1 of the drone base station, the base station floor 11 serves as the bottom foundation to support the drone antenna 12 for operation, and the side support frame 13 and the corner snap-fit ​​frame 14 are first assembled, and then the connecting card block 15 is added to fix it. The side support frame 13 adopts a layered structure, and then, according to actual flight needs, the side support frame 13 of appropriate height can be selected to cooperate with the corner snap-fit ​​frame 14 and the connecting card block 15 to assemble into the entire base station floor 11, thereby realizing an integral take-off and landing platform suitable for drones.

[0032] As an optimization solution, the external support frame 2 includes two transverse support rods 21, and a connecting skeleton 22 is installed between the two transverse support rods 21. The transverse support rods 21 and the connecting skeleton 22 are both fixed to the bottom of the drone base station body 1.

[0033] Specifically, in the external support frame 2, the transverse support rod 21 cooperates with the connecting skeleton 22 to form the bottom support of the drone base station body 1, so that the bottom of the base station floor 11 can be more stably supported on the ground, soil or sand.

[0034] As an optimization solution, the wind and sand shielding assembly 3 includes two first servo motors 35 and two support rings 34. The two support rings 34 are fixed to the transverse support rod 21. The output shafts of the two first servo motors 35 are connected to the first threaded rotating rod 32 through a coupling. The top ends of the two first threaded rotating rods 32 pass through and extend out of the transverse support rod 21. The two first threaded rotating rods 32 are threadedly connected with a threaded lifting connecting block 33, and a wind and sand shielding curtain 31 is connected between the two threaded lifting connecting blocks 33; wherein, two longitudinal support rods 23 are installed on the two transverse support rods 21, and multiple threaded lifting connecting blocks 33 are slidably connected to adjacent longitudinal support rods 23. The two first threaded rotating rods 32 are rotatably connected to the support rings 34, and the wind and sand shielding curtains 31 are connected to adjacent support rings 34. The bottoms of the four first servo motors 35 are all equipped with a connecting base 36

[0035] Specifically, the first servo motor 35, the connecting base 36 and the external support frame 2 are combined to realize the bottom support for the drone base station body 1, and in this process, starting the first servo motor 35 can drive the first threaded rotating rod 32 to rotate, and the support ring 34 cooperates with the external support frame 2 to make the first threaded rotating rod 32 rotate more stably. The presence of the longitudinal support rod 23 allows the threaded lifting connection block 33 to stably drive the wind and sand shielding curtain 31 to move up and down. When the threaded lifting connection block 33 moves to the top, the wind and sand shielding curtain 31 can be fully unfolded to resist the wind and sand on this side from blowing towards the drone base station body 1. After the wind and sand pass, you only need to start the first servo motor 35 to rotate in the opposite direction, and multiple first servo motors 35 rotate synchronously, ensuring the controllability of the unfolding of the wind and sand shielding curtain 31.

[0036] As an optimization scheme, the auxiliary support member 4 includes a second threaded rotating rod 42 and a second servo motor 49. The second threaded rotating rod 42 is threadedly connected to a threaded positioning ring 43, which is fixed to the bottom of the drone base station body 1. A driving gear ring 44 is installed on the threaded positioning ring 43, and a driving gear 45 is installed on the second servo motor 49. The driving gear 45 is engaged with the adjacent driving gear ring 44. One end of the second threaded rotating rod 42 is connected to a propulsion plate 46, which is located between the adjacent wind and sand shielding component 3 and the drone base station body 1. An auxiliary support block 47 is installed on the top of the propulsion plate 46, and auxiliary rubber rods 48 are hinged at both ends of the auxiliary support block 47. The two auxiliary rubber rods 48 are both rotatably connected to the wind and sand shielding component 3. A limiting slider 41 is installed on the end of the second threaded rotating rod 42 away from the propulsion plate 46, and the limiting slider 41 is slidably connected to the bottom of the drone base station body 1.

[0037] Specifically, when the wind and sand are strong, starting the second servo motor 49 can drive the driving gear 45 to rotate, and the threaded positioning ring 43 is rotated by the driving gear 45. Under the limit of the limit slider 41, the second threaded rotating rod 42 can push the propulsion plate 46 toward the wind and sand shielding curtain 31. The propulsion plate 46 contacts the wind and sand shielding curtain 31 and will gradually move to cooperate with the threaded lifting connecting block 33 and the support ring 34 to tighten the wind and sand shielding curtain 31, thereby further resisting wind and sand erosion. In this process, the auxiliary support block 47 and the auxiliary rubber rod 48 will provide auxiliary support, and the auxiliary rubber rod 48 will be slightly deformed during the movement of the auxiliary support block 47, thereby providing auxiliary support.

[0038] Working principle: This device adds an external support frame 2 to the bottom of the drone base station body 1 to elevate the entire drone base station body 1. At the same time, it can add a wind and sand shielding component 3 to achieve an effective wind and sand protection for the drone base station body 1 and the multiple drone antennas 12 inside the drone base station body 1, preventing the wind and sand from directly invading the drone base station body 1 and breaking the drone antenna 12 or eroding the surface of the drone antenna 12, causing damage to the drone antenna 12. The addition of an auxiliary support member 4 can further assist the wind and sand shielding component 3 and increase its wind and sand resistance.

[0039] In the drone base station body 1, the base station floor 11 serves as the bottom foundation to support the drone antenna 12 for operation, and the side support frames 13 and the corner snap-fit ​​frames 14 are first assembled, and then the connecting blocks 15 are added to fix them. The side support frames 13 adopt a layered structure, and the side support frames 13 of appropriate height can be selected according to actual flight needs to cooperate with the corner snap-fit ​​frames 14 and the connecting blocks 15 to assemble the entire base station floor 11, thereby realizing an integral take-off and landing platform suitable for drones.

[0040] In the external support frame 2, the transverse support rod 21 cooperates with the connecting skeleton 22 to form the bottom support of the drone base station body 1, so that the bottom of the base station floor 11 can be more stably supported on the ground, soil or sand.

[0041] In the wind and sand shielding assembly 3, the first servo motor 35, the connecting base 36 and the external support frame 2 are combined to realize the bottom support of the drone base station body 1, and in this process, starting the first servo motor 35 can drive the first threaded rotating rod 32 to rotate, and the support ring 34 cooperates with the external support frame 2 to make the first threaded rotating rod 32 rotate more stably, and the existence of the longitudinal support rod 23 allows the threaded lifting connecting block 33 to stably drive the wind and sand shielding curtain 31 to move up and down. When the threaded lifting connecting block 33 moves to the top, the wind and sand shielding curtain 31 can be fully unfolded to resist the wind and sand on this side from blowing towards the drone base station body 1. After the wind and sand pass, it is only necessary to start the first servo motor 35 to rotate in the opposite direction, and multiple first servo motors 35 rotate synchronously, ensuring the controllability of the unfolding of the wind and sand shielding curtain 31;

[0042] When the wind and sand are strong, the second servo motor 49 is started to drive the driving gear 45 to rotate, and the threaded positioning ring 43 is rotated by the driving gear 45. Under the limit of the limit slider 41, the second threaded rotating rod 42 can push the propulsion plate 46 toward the direction of the wind and sand shielding curtain 31. The propulsion plate 46 contacts the wind and sand shielding curtain 31 and gradually moves to cooperate with the threaded lifting connecting block 33 and the support ring 34 to tighten the wind and sand shielding curtain 31, thereby further resisting the erosion of wind and sand. In this process, the auxiliary support block 47 and the auxiliary rubber rod 48 will provide auxiliary support, and the auxiliary rubber rod 48 will be slightly deformed during the movement of the auxiliary support block 47, thereby providing auxiliary support.

[0043] The material of the wind and sand shielding curtain 31 can be a composite material, using conventional curtain cloth plus Oxford cloth, and adding soft steel wire inside, which can resist wind and sand while extending the overall service life.
