Description

Technical Field

[0001] This invention relates to the field of antenna support technology, and in particular to a corrosion-resistant antenna support that can be connected to a steel guardrail. Background Technology

[0002] An antenna, as a converter, can transform guided waves propagating on a transmission line into electromagnetic waves propagating in the air, or vice versa. It is a component in wireless equipment used to transmit or receive electromagnetic waves. It is widely used in engineering systems such as radio communication, broadcasting, television, and navigation.

[0003] With the rapid development of wireless communication engineering, antennas are needed near national highways and expressways for signal transmission and reception to meet the communication needs of vehicles traveling on roads. Currently, the common practice is to construct independent signal brackets on the ground outside the highway to install antennas, thus meeting the communication coverage requirements of telecommunications operators for the highway and surrounding environment. However, constructing independent signal brackets outside the highway involves a large amount of installation work, occupies a large area, and is incompatible with the surrounding environment. Because they are fixed outdoors, adjusting the height requires workers to climb, which is inconvenient. Furthermore, the fixed antenna brackets cannot be retracted for protection even when not in use. In coastal areas, the antenna brackets are prone to corrosion due to the corrosive atmosphere. Summary of the Invention

[0004] Based on this, the present invention provides a corrosion-resistant antenna bracket that connects to steel guardrails, so as to stably connect with and structurally adapt to the steel guardrails on both sides of the highway, reduce the land area and construction work, and realize the antenna to be stably supported and flexibly raised and lowered, and retract into a corrosion-resistant protective state when not in use.

[0005] To achieve the above objectives, the present invention provides a corrosion-resistant antenna bracket connected to a steel guardrail. A left and right lifting bracket are symmetrically mounted across the steel guardrail with their movable ends extending upwards. An antenna mounting base is positioned directly above the steel guardrail and extends horizontally. The movable ends of the left and right lifting brackets are connected to the bottom of the antenna mounting base. A protective housing is located outside the steel guardrail and has a vertical through space to accommodate the left and right lifting brackets. A drive mechanism is connected to the left and right lifting brackets and is configured to drive the movable ends of the left and right lifting brackets to rise and fall synchronously, thereby lowering the antenna mounting base and forming an upper closed structure with the protective housing.

[0006] Furthermore, the protective housing is symmetrically arranged on both sides of the top of the steel guardrail, and the protective housing and the steel guardrail are spaced apart to form a vertical through space. The left and right lifting brackets are movably arranged in the vertical through space. After the antenna mounting base is lowered, it is fastened to the upper opening of the protective housing to form an upper closed structure.

[0007] Furthermore, the left and right lifting brackets each include two sets of scissor link assemblies symmetrically arranged on both sides of the steel guardrail in the thickness direction and in the gap between the guardrail and the protective shell. The top of each set of scissor link assemblies is connected to the outside of the antenna mounting base. The driving mechanism is driven by each set of scissor link assemblies to drive each set of scissor link assemblies to move synchronously.

[0008] Furthermore, the antenna mounting base is connected to the plate antenna on both sides of its width direction via hinges arranged horizontally along the pivot. The antenna mounting base is equipped with a flipping drive mechanism that drives the plate antenna to rotate around the hinges. When in operation, the antenna mounting base is raised, and the flipping drive mechanism drives the plate antenna to flip upward to a horizontal state. When not in operation, the flipping drive mechanism drives the plate antenna to flip downward to a vertical state, and the antenna mounting base is lowered, which in turn drives the plate antenna into the protective housing.

[0009] Furthermore, the antenna bracket also includes a control unit, which receives the operating status information of the installed antenna. When the antenna is detected to be not in operation, the control unit controls the antenna bracket to retract into the protective housing. When the antenna is detected to be in operation, the control unit controls the antenna bracket to extend out of the protective housing. And / or, the control unit receives weather condition information transmitted from the outside and controls the drive mechanism to operate according to the weather condition information, so as to control the antenna bracket to retract into the protective housing under the set weather conditions.

[0010] Furthermore, a bottom horizontal guide rail is provided near the upper end of the steel guardrail along its length. The bottom horizontal guide rail is provided with a bottom left end lug and a bottom right end lug at both ends. One bottom link of the left scissor link assembly extends to the lower left and is hinged to the bottom left end lug, while the other bottom link extends to the lower right and is connected to the left bottom roller. One bottom link of the right scissor link assembly extends to the lower right and is hinged to the bottom right end lug, while the other bottom link extends to the lower left and is connected to the right bottom roller. The left and right bottom rollers are supported on the bottom horizontal guide rail.

[0011] Furthermore, the left bottom roller and the right horizontal roller are respectively provided with wheel grooves adapted to the thickness of the horizontal guide rail. The wheel shaft of the left bottom roller extends symmetrically to both ends, and a pair of bottom connecting rods symmetrically arranged on both sides of the steel guardrail are respectively connected to both ends of the wheel shaft of the left bottom roller. The wheel shaft of the right horizontal roller extends symmetrically to both ends, and another pair of bottom connecting rods symmetrically arranged on both sides of the steel guardrail are connected to both ends of the wheel shaft of the right bottom roller.

[0012] Furthermore, the antenna mounting base is provided with a top horizontal guide rail along its length. The top horizontal guide rail is provided with a top left end ear and a top right end ear at its two ends, respectively. One top link of the left scissor link assembly extends to the upper left and is hinged to the top left end ear, while the other top link extends to the upper right and is connected to the left top roller. Similarly, one top link of the right scissor link assembly extends to the upper right and is hinged to the top right end ear, while the other top link extends to the upper left and is connected to the right top roller. The left and right top rollers are supported on the top horizontal guide rail.

[0013] Compared to existing technologies, the technical advantages of the corrosion-resistant antenna bracket provided for connection with steel guardrails are at least reflected in the following aspects:

[0014] 1. The antenna mounting base is driven to rise and fall by symmetrically installed left and right lifting brackets on the steel guardrail, which enables flexible adjustment and stable support of the antenna mounting base and antenna. A protective shell is set on the outside of the steel guardrail to accommodate the left and right lifting brackets. After the antenna mounting base is lowered, it forms an upper closed structure with the protective shell, which can enclose and protect the retracted left and right lifting brackets, prevent rainwater erosion, and make the entire antenna support have good corrosion resistance.

[0015] 2. The left and right lifting supports each include scissor link assemblies arranged in the gap between the steel guardrail and the protective shell on both sides of the thickness direction. The scissor link assemblies on both sides of the steel guardrail are connected by top rollers and bottom rollers that slide along the transverse guide rail, forming a stable integrated structure with the steel guardrail. This forms a spatial truss that provides stable support for the antenna mounting base, resisting strong winds and other external forces. It also occupies little space outside the steel guardrail and blends in with the surrounding environment.

[0016] 3. By flipping the plate antenna on both sides of the antenna mounting base, during operation, the left and right lifting brackets extend from the protective housing, driving the antenna mounting base to rise, and the plate antenna flips upward to the unfolded state for signal reception. When not in operation, the plate antenna flips downward to both sides of the left and right lifting brackets, and retracts into the protective housing along with the left and right lifting brackets. The antenna mounting base and the protective housing form an upper closed structure, which not only provides corrosion protection for the lifting frame and drive mechanism, but also for the plate antenna, effectively resisting external damage and improving safety during use.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 10 As shown, the present invention provides a corrosion-resistant antenna bracket connected to a steel guardrail 1, including a left lifting bracket 31a and a right lifting bracket 31b, an antenna mounting base 5, a protective housing 2, and a drive mechanism 4. The left lifting bracket 31a and the right lifting bracket 31b are symmetrically straddling the steel guardrail 1 and their movable ends extend upwards. The antenna mounting base 5 is arranged directly above the steel guardrail 1 and extends horizontally. The movable ends of the left lifting bracket 31a and the right lifting bracket 31b are connected to the bottom of the antenna mounting base 5. The protective housing 2 is disposed on the outside of the steel guardrail 1 and has a vertical through space to accommodate the left lifting bracket 31a and the right lifting bracket 31b. The drive mechanism 4 is drivenly connected to the left lifting bracket 31a and the right lifting bracket 31b and is configured to drive the movable ends of the left lifting bracket 31a and the right lifting bracket 31b to rise and fall synchronously, thereby lowering the antenna mounting base 5 and forming an upper closed structure with the protective housing.

[0040] The provided corrosion-resistant antenna bracket, which connects to a steel guardrail, features a left lifting bracket 31a and a right lifting bracket 31b symmetrically mounted on the steel guardrail 1. These brackets are driven synchronously by a drive mechanism to adjust the lifting of the antenna mounting base 5. This allows for flexible lifting and stable support of the antenna mounting base 5 and the antenna. The bracket is suitable for installing large antennas, occupies little space outside the guardrail, and blends well with the surrounding environment. It is ideal for long-term use in densely populated areas such as residential communities and streets.

[0041] During implementation, the left lifting bracket 31a and right lifting bracket 31b, antenna mounting base 5, protective housing 2, and drive mechanism 4 are all made of stainless steel to provide corrosion resistance.

[0042] During implementation, the protective housing 2 is symmetrically arranged on both sides of the top of the steel guardrail 1. The protective housing 2 and the steel guardrail 1 are spaced apart to form a vertical through space. The left lifting bracket 31a and the right lifting bracket 31b are movably arranged within the vertical through space. After the antenna mounting base 5 is lowered, it is fastened to the upper opening of the protective housing 2 to form an upper closed structure. Based on the above structure, a protective housing 2 is set on the outside of the steel guardrail 2 to accommodate the left lifting bracket 31a and the right lifting bracket 31b. After the antenna mounting base 5 is lowered, it forms an upper closed structure with the protective housing 2, which can seal and protect the retracted left lifting bracket 31a and the right lifting bracket 31b, avoiding rainwater erosion, so that the entire antenna support has good corrosion resistance.

[0043] like Figure 11 and Figure 12 As shown, in some embodiments, the antenna mounting base 5 is connected to the plate antenna 6 on both sides of its width direction via hinges arranged horizontally along a rotating shaft. The antenna mounting base 5 is provided with a flipping drive mechanism that drives the plate antenna 6 to rotate around the hinges. When working, the antenna mounting base 5 is raised, and the flipping drive mechanism drives the plate antenna 6 to flip upward to a horizontal state. When not working, the flipping drive mechanism drives the plate antenna 6 to flip downward to a vertical state, and the antenna mounting base 5 is lowered and drives the plate antenna 6 into the protective housing 2.

[0044] During use, the plate antenna 6 can be flipped to connect to both sides of the antenna mounting base 5. When working, the left lifting bracket 31a and the right lifting bracket 31b extend from the protective housing 2 to drive the antenna mounting base 5 to rise, and the plate antenna 6 flips upward to the unfolded state for signal reception. When not working, the plate antenna 6 flips downward to both sides of the left lifting bracket 31a and the right lifting bracket 31b. The plate antenna retracts into the protective housing 2 along with the left lifting bracket 31a and the right lifting bracket 31b. The antenna mounting base 5 and the protective housing 2 form an upper closed structure, which not only provides corrosion protection for the lifting bracket and the drive mechanism 4, but also provides corrosion protection for the plate antenna 6, effectively resisting external damage and improving the safety of use.

[0045] Furthermore, the antenna bracket also includes a control unit, which receives the operating status information of the installed antenna. When the antenna is detected to be not in operation, the control unit controls the antenna bracket to retract into the protective housing 2. When the antenna is detected to be in operation, the control unit controls the antenna bracket to extend out of the protective housing 2. And / or, the control unit receives weather condition information transmitted from the outside and controls the drive mechanism 4 to operate according to the weather condition information, so as to control the antenna bracket to retract into the protective housing 2 under the set weather conditions.

[0046] In some embodiments, the left lifting bracket 31a and the right lifting bracket 31b each include two sets of scissor link assemblies symmetrically arranged on both sides of the steel guardrail 1 in the thickness direction within the gap between the guardrail and the protective shell. The top of each set of scissor link assemblies is connected to the outer side of the antenna mounting base 5. The driving mechanism 4 is driven by each set of scissor link assemblies to drive them to move synchronously. The scissor link assemblies have the characteristics of occupying little space outside the guardrail and having a large lifting height. They are arranged on both sides of the rear end of the guardrail, forming an integrated structure with the steel guardrail 1, and are easy to install and adjust.

[0047] Furthermore, during implementation, a bottom horizontal guide rail is provided near the upper end of the steel guardrail 1 along its length. Bottom left end lugs and bottom right end lugs are respectively provided at both ends of the bottom horizontal guide rail. One bottom link of the left scissor link assembly extends to the lower left and is hinged to the bottom left end lug, while the other bottom link extends to the lower right and is connected to the left bottom roller 32a. One bottom link of the right scissor link assembly extends to the lower right and is hinged to the bottom right end lug, while the other bottom link extends to the lower left and is connected to the right bottom roller 32b. The left bottom roller 32a and the right bottom roller 32b are supported on the bottom horizontal guide rail. During implementation, the left bottom roller 32a and the right horizontal roller are respectively provided with wheel grooves adapted to the thickness of the horizontal guide rail. The wheel shaft of the left bottom roller 32a extends symmetrically to both ends. A pair of bottom connecting rods symmetrically arranged on both sides of the steel guardrail 1 are connected to both ends of the wheel shaft of the left bottom roller 32a. The wheel shaft of the right horizontal roller extends symmetrically to both ends. Another pair of bottom connecting rods symmetrically arranged on both sides of the steel guardrail 1 are connected to both ends of the wheel shaft of the right bottom roller 32b.

[0048] Based on the above embodiments, the bottom roller is supported on the bottom horizontal guide rail of the steel guardrail 1, and the bottom ear seat constrains the movement of the bottom of the scissor linkage assembly, improving the stability of the telescopic action. In addition, the bottom roller establishes a lateral connection at the bottom of the scissor linkage assembly on both sides of the steel guardrail 1, so that the bottom of the scissor linkage assembly on both sides forms an integrated structure, providing stable support and lifting adjustment for the antenna mounting base 5.

[0049] In some embodiments, the antenna mounting base 5 is provided with a top horizontal guide rail along its length. A top left end lug and a top right end lug are respectively provided at both ends of the top horizontal guide rail. One top link of the left scissor link assembly extends to the upper left and is hinged to the top left end lug; the other top link extends to the upper right and is connected to the left top roller 36a. One top link of the right scissor link assembly extends to the upper right and is hinged to the top right end lug; the other top link extends to the upper left and is connected to the right top roller 36b. The left top roller 36a and the right top roller 36b are supported opposite each other on the top horizontal guide rail. Based on the above embodiments, the top rollers, supported on the top horizontal guide rail of the antenna mounting base, combined with the top lugs, constrain the movement of the top of the scissor link assembly, improving the stability of the telescopic movement. Furthermore, the top rollers establish a lateral connection at the top of the scissor link assemblies on both sides of the steel guardrail 1, forming an integrated structure at the top of the scissor link assemblies on both sides, thus providing stable support for the antenna mounting base 5.

[0050] like Figure 4 and Figure 9As shown, during implementation, the drive mechanism 4 includes a rotary motor 41 centrally located at the bottom of the antenna mounting base 5. The rotating shaft of the rotary motor 41 is arranged along the length of the antenna mounting base 5 and extends symmetrically at both ends. A left-handed screw 42a and a right-handed screw 42b are symmetrically connected to the rotating shafts at both ends. The axle of the left top roller 36a is provided with a left-handed nut seat 43a connected to the left-handed screw 42a, and the axle of the right top roller 36b is provided with a right-handed nut seat 43b connected to the right-handed screw 42b. The left top roller 36a and the right top roller 36b each include two half-wheels rotatably disposed at both ends of the axle. The left-handed nut seat 43a and the right-handed nut seat 43b are fixedly disposed in the middle of the axle, and the rim spacing of the two half-wheels is adapted to the thickness of the top horizontal guide rail. The left lifting bracket 31a and the right lifting bracket 31b are synchronously adjusted by the symmetrically arranged left and right spiral screws driven by the aforementioned rotary motor 41. The process is stable and balanced, and the drive mechanism 4 is small in size, making it suitable for use at the bottom of the antenna mounting base 5.

[0051] In some embodiments, the axle of the left bottom roller 32a is also connected to a left auxiliary connecting rod 33a extending downward to the right. The left bottom ear is connected to the left auxiliary connecting rod 33a via a left half connecting rod 34a. A left auxiliary roller 35a is provided at the lower end of the left auxiliary connecting rod 33a, and the left auxiliary roller 35a is supported on the left vertical guide rail below the left ear. The axle of the right bottom roller 32b is also connected to a right auxiliary connecting rod 33b extending downward to the left. The right bottom ear is connected to the right auxiliary connecting rod 33b via a right half connecting rod 34b. A right auxiliary roller 35b is provided at the lower end of the right auxiliary connecting rod 33b, and the right auxiliary roller 35b is supported on the left vertical guide rail below the right ear. Furthermore, the axle of the left auxiliary roller 35a extends symmetrically to both ends, and the left auxiliary connecting rods 33a, symmetrically arranged on both sides of the steel guardrail 1, are connected to both ends of the axle of the left auxiliary roller 35a. Similarly, the axle of the right auxiliary roller 35b extends symmetrically to both ends, and the right auxiliary connecting rods 33b, symmetrically arranged on both sides of the steel guardrail 1, are connected to both ends of the axle of the right auxiliary roller 35b. The auxiliary connecting rods and rollers not only improve the vertical support at the bottom of the left lifting support 31a and the right lifting support 31b, but also establish a lateral connection between them, thereby increasing structural strength.

[0052] Based on the above embodiments, the left lifting bracket 31a and the right lifting bracket 31b respectively include scissor link assemblies arranged in the gap between the steel guardrail 1 and the protective shell 2 on both sides in the thickness direction. The scissor link assemblies on both sides of the steel guardrail 1 are supported and connected by top rollers, bottom rollers and auxiliary rollers that slide along the transverse guide rail, and establish a stable integrated structure with the steel guardrail 1 to form a spatial truss to stably support the antenna mounting base 5. It can resist strong wind and other external forces, and occupies little space outside the steel guardrail 1, blending into the surrounding environment.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
