Description

Technical Field

[0001] This invention relates to the field of base station antenna design technology, specifically to a connection protection structure for base station antennas. Background Technology

[0002] Base station antennas are key devices in wireless communication networks used to transmit and receive radio signals. They are installed on base station towers or other high ground and transmit radio waves to a certain range through antenna arrays, while simultaneously receiving signals from mobile devices (such as mobile phones and tablets). The main functions of base station antennas are to expand communication coverage, enhance signal strength, and improve data transmission rates. The design and location of antennas are crucial to ensuring the stability and reliability of wireless networks. They must be able to effectively handle various environmental factors, such as weather conditions, building obstructions, and interference signals, to ensure that users can obtain a good communication experience.

[0003] The base station antenna is connected by a high-strength connector support structure to ensure effective signal transmission. The connector is usually waterproof, dustproof and corrosion-resistant to adapt to various harsh environments. At this time, the signal enters the antenna from the feeder, and after being processed by internal filtering and matching circuits, it is amplified or reduced to an appropriate level. During this process, the protective structure provides a stable environment to prevent external factors such as rain, dust and extreme temperatures from interfering with signal transmission. Finally, the processed signal is radiated out by the antenna to cover the service area, while receiving signals from mobile devices and returning them to the base station for processing through the same connection and protective structure.

[0004] The current equipment still has some inconveniences in use: base station antennas are usually tilted at high altitudes. Tilting the antenna can adjust the angle of signal propagation, optimize the vertical coverage of the signal, and reduce the horizontal spread of the signal, thereby improving spectrum efficiency and reducing interference. However, tilted base station antennas are easily affected by low temperatures and snowfall, and ice and snow layers are easily formed on the tilted side and the top of the antenna. Since base station antennas are often in high positions, manual cleaning is not only dangerous but also inefficient. At this time, the ice and snow layer will increase the resistance at the connection point between the antenna and the feeder, resulting in signal loss and communication interruption.

[0016] Preferably, both ends of the limiting rod are provided with inclined surfaces, with the upward-facing end of the limiting rod located inside the sliding path of the locking block, and the downward-facing end of the limiting rod located inside the sliding path of the side locking rod.

[0017] Beneficial effects

[0018] The connection protection structure for base station antennas provided by this invention has the following beneficial effects:

[0019] 1. Through the cooperation of the bottom bracket and the vibrating slide frame, as the vibrating slide frame slides upward, the first gear on the surface of the vibrating slide frame meshes with the toothed block on the inner wall surface of the antenna frame, thereby rotating and driving the adjusting rotating rod to rotate. This causes the rubber hammer to swing back and forth by applying the pushing force of the contact inclined block and the opposing pushing force of the rebound lever, thereby striking the side of the antenna frame surface where ice and snow have accumulated, thus reducing the adhesion between the ice and snow layer and the antenna frame surface. At this time, the antenna frame gradually changes from a tilted state to a vertical state, and the ice and snow layer on the antenna frame surface automatically detaches from the antenna frame surface under the action of gravity, thereby achieving automatic cleaning of the ice and snow layer on the antenna frame surface.

[0020] 2. Through the cooperation of the bottom bracket and the antenna frame, during the rotation of the antenna frame, the internal axial rod rotates relative to the antenna frame under the restriction of the bottom bracket. This drives the lifting adjustment shaft to rotate through the transmission mechanism. At this time, the rotation of the lifting adjustment shaft provides an upward thrust to the vibrating slide frame through the inclined groove of the surface lifting groove, thereby driving the vibrating slide frame to slide upward until the vibrating slide frame slides to the top of the antenna frame and descends through the straight slide groove. The lifting adjustment shaft drives the vibrating slide frame to swing back and forth inside the antenna frame, thereby improving the vibration of the ice and snow layer at various positions on the surface of the antenna frame, thus improving the vibration effect.

[0021] 3. Through the coordinated use of the top frame and the main rod, the horizontal clamping shaft pushes the horizontal scraper out of the interior of the top frame through the second groove on the surface, thereby scraping away the snow on the top of the antenna frame. The lifting groove is driven by the first groove to slide from top to bottom, thereby scraping away the snow on the sloping surface of the antenna frame. Since the antenna frame has already been broken by vibration with a rubber hammer during the retraction process, the scraping action of the axial rod and the lifting groove at this time, through the method of vibration followed by scraping, can effectively reduce the adhesion between the ice and snow and the structural surface, reduce the damage to the surface during the scraping process, avoid the problem of residual snow or ice on the surface of the antenna frame, and improve the cleaning efficiency.

[0033] 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. 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.

[0034] refer to Figures 1 to 9 A preferred embodiment of the present invention, a connection protection structure for a base station antenna, will be described in detail below.

[0035] A connection protection structure for a base station antenna includes a support column 1. The surface of the support column 1 is provided with a bottom bracket 2 and a top frame 3. The surface of the bottom bracket 2 is provided with an antenna frame 412 to protect the antenna. The inside of the antenna frame 412 is provided with a placement plate 414 for mounting the antenna. The inside of the antenna frame 412 is provided with a rubber hammer 419 for vibrating and clearing the ice and snow layer on the surface of the antenna frame 412, and an adjusting rotating rod 4111. The inside of the antenna frame 412 is provided with a lifting adjusting shaft 415 and a vibration sliding frame 418 for driving the contact inclined block 4112 to clear the ice and snow layer on the side of the antenna frame 412 that is prone to snow accumulation.

[0036] The top frame 3 has a side slide plate 512 and a vertical scraper 516 inside for scraping snow on the slope of the antenna frame 412. The top frame 3 also has a vertical slide plate 5111 and a horizontal scraper 517 inside for scraping the top of the antenna frame 412. The top frame 3 also has a main rod 511 inside for providing power to the horizontal scraper 517 and the vertical scraper 516.

[0037] like Figure 2 , Figure 3 and Figure 4In this structure, the top frame 3 has connecting rods 411 at both ends. The antenna frame 412 is rotatably connected to one end of the connecting rod 411, and one end of the antenna frame 412 is rotatably connected to the inner surface of the bottom support 2. A pressure sensor is installed inside the top frame 3. When ice accumulates on the surface of the antenna frame 412 to a certain extent, the pressure sensor controls the electric telescopic rod inside the top frame 3 to apply an upward pulling force to the connecting rod 411, thereby causing the antenna frame 412 to rotate around the surface of the bottom support 2 until it changes from an inclined state to a vertical state. The bottom of the antenna frame 412 has a bottom sealing plate 413, which is fixedly connected to the placement plate 414. The antenna frame 412 has an axial circular rod 417 inside, which extends into the interior of the bottom support 2. The lifting adjustment shaft 415 is located inside the antenna frame 412. A lifting groove 416 is formed on the surface of the lifting adjustment shaft 415. A vibrating slide frame 418 is slidably connected to the inside of the antenna frame 412. One end of the vibrating slide frame 418 extends into the lifting groove 416. The lifting groove 416 consists of a straight groove and an inclined groove. The depth of the straight groove is greater than the depth of the inclined groove. During the rotation of the antenna frame 412, the internal axial rod 417 rotates relative to the antenna frame 412 under the constraint of the bottom bracket 2. This rotation drives the lifting adjustment shaft 415 to rotate via the transmission mechanism. The rotation of the lifting adjustment shaft 415 then provides an upward thrust to the vibrating slide frame 418 through the inclined groove of the lifting groove 416, causing the vibrating slide frame 418 to slide upwards. Figure 5 and Figure 9In this structure, a rubber hammer 419 is located inside a vibrating slide frame 418. A first gear 4110 is provided on one end of the surface of the vibrating slide frame 418, extending into the interior of the vibrating slide frame 418. An adjusting rotating rod 4111 is located on one end surface of the first gear 4110. A rebound paddle 4113 is provided inside the vibrating slide frame 418, positioned within the swing path of the rubber hammer 419. A contact inclined block 4112 is fixedly connected to the surface of the rubber hammer 419, located within the rotation path of the adjusting rotating rod 4111. Inclined surfaces are provided on both sides of the contact inclined block 4112. The adjusting rotating rod 4111 is positioned at the center line of the inclined surfaces on both sides of the contact inclined block 4112. During the upward sliding of the vibrating slide frame 418, the first gear on the surface of the vibrating slide frame 418... The toothed block 4110 meshes with the toothed block on the inner wall surface of the antenna frame 412, thereby rotating and driving the adjusting rotating rod 4111 to rotate. This causes the rubber hammer 419 to swing back and forth by applying a pushing force to the contact inclined block 4112 and a reverse pushing force to the return lever 4113. This strikes the side of the antenna frame 412 where ice and snow have accumulated, thereby reducing the adhesion between the ice and snow layer and the surface of the antenna frame 412. At this time, the antenna frame 412 gradually changes from an inclined state to a vertical state. Under the action of gravity, the ice and snow layer on the surface of the antenna frame 412 automatically detaches from the surface of the antenna frame 412, thereby achieving automatic cleaning of the ice and snow layer on the surface of the antenna frame 412. Furthermore, the lifting adjusting shaft 415 drives the vibrating sliding frame 418 to swing back and forth inside the antenna frame 412, thereby improving the cleaning effect of the ice and snow layer at various positions on the surface of the antenna frame 412.

[0038] pass Figure 7 and Figure 8 In the middle, the main body rod 511 is slidably connected to the inside of the top frame 3, and the main body rod 511 is located in the sliding path of the supporting side rod 4114. The side slide plate 512 is slidably connected to the inside of the top frame 3. A first slot 514 is opened on the surface of the side slide plate 512, and a contact pin 513 is provided inside the first slot 514. Figure 9In the middle, a vertical scraper 516 is provided on the inner wall surface of the top frame 3, and the vertical scraper 516 is fixedly connected to the contact pin 513. A pull rod 515 is provided between the side slide plate 512 and the main rod 511. The vertical slide plate 5111 is provided inside the top frame 3 and is located on the sliding path of the main rod 511. A second slot 5113 is opened on the surface of the vertical slide plate 5111, and a horizontal pin 5112 is provided inside the second slot 5113. A horizontal scraper 517 is provided on the inner wall of the top frame 3 and is fixedly connected to the horizontal pin 5112. A locking block 518 is provided at the bottom of the main rod 511. A limit rod 519 is slidably connected inside the top frame 3. A side locking rod is provided at one end of the supporting side rod 4114. 5110, both ends of the limiting rod 519 are provided with inclined surfaces. The upward-facing end of the limiting rod 519 is located inside the sliding path of the locking block 518, and the downward-facing end of the limiting rod 519 is located inside the sliding path of the side locking rod 5110. When the antenna frame 412 is angled, the supporting side rod 4114 slides downward, pushing the main rod 511 downward. The main rod 511 pushes the side sliding plate 512 to the right through the pulling rod 515, and moves the vertical scraper 516 to the inner wall above the top frame 3 through the first slot 514 on the surface. At this time, during the downward sliding of the main rod 511, the vertical sliding plate 5111 slides downward with the main rod 511 under the action of the spring, thereby driving the horizontal scraper 5 through the second slot 5113. 17 retracts to the inside of the top frame 3. Simultaneously, when the supporting side rod 4114 slides to the bottom, the locking block 518 at the bottom of the main body rod 511 contacts the inclined surface of the limiting rod 519. The limiting rod 519 extends into the locking block 518, thus limiting the main body rod 511. When the surface of the antenna frame 412 is covered with ice and snow, after the top frame 3 has retracted the antenna frame 412, the side locking rod 5110 pushes the limiting rod 519 to slide away from the antenna frame 412, thereby releasing the limitation on the main body rod 511. The main body rod 511 slides upward under the action of the spring, thereby driving the transverse locking shaft 5112 to slide upward. At this time, the transverse locking shaft 5112 pushes the transverse scraper 517 out of the top frame 3 through the second locking groove 5113 on the surface. Inside, the snow on the top of the antenna frame 412 is scraped away. As the main body rod 511 slides upward, it drives the side slide plate 512 to slide closer to the antenna frame 412 via the pull rod 515. It also drives the lifting groove 416 to slide from top to bottom via the first slot 514, thereby scraping away the snow on the slope of the antenna frame 412. Since the antenna frame 412 has already been broken by vibration with the rubber hammer 419 during the closing process, the scraping action of the axial round rod 417 and the lifting groove 416 at this time, by vibrating first and then scraping, can effectively reduce the adhesion between the ice and snow and the structural surface, reduce the damage to the surface during the scraping process, avoid the problem of residual snow or ice on the surface of the antenna frame 412, and improve the cleaning efficiency.

[0039] The following is the complete working process and working principle of the above embodiment: A pressure sensor is installed inside the top frame 3. When ice accumulates on the surface of the antenna frame 412 to a certain extent, the pressure sensor controls the electric telescopic rod inside the top frame 3 to exert an upward pulling force on the connecting rod 411, thereby causing the antenna frame 412 to rotate around the surface of the bottom support 2 until it changes from an inclined state to a vertical state. Simultaneously, during the rotation of the antenna frame 412, the internal axial rod 417 rotates relative to the antenna frame 412 under the constraint of the bottom support 2, thereby driving the lifting adjustment shaft 415 to rotate through the transmission mechanism. At this time, the rotation of the lifting adjustment shaft 415, through the inclined groove of the surface lifting groove 416, gives an upward thrust to the vibrating slide frame 418, thereby driving... As the vibrating slide frame 418 slides upward, the first gear 4110 on the surface of the vibrating slide frame 418 meshes with the toothed block on the inner wall surface of the antenna frame 412, causing it to rotate. This, in turn, drives the adjusting rotating rod 4111 to rotate, thereby providing a pushing force to the contact inclined block 4112 and a counter-pushing force to the return lever 4113, causing the rubber hammer 419 to swing back and forth. This taps the side of the antenna frame 412 where ice and snow have accumulated, reducing the adhesion between the ice and snow layer and the surface of the antenna frame 412. At this time, the antenna frame 412 gradually changes from an inclined state to a vertical state. Under the action of gravity, the ice and snow layer on the surface of the antenna frame 412 automatically detaches from the surface of the antenna frame 412, thus achieving automatic cleaning of the ice and snow layer on the surface of the antenna frame 412. The lifting adjustment shaft 415 drives the vibrating slide frame 418 to swing back and forth inside the antenna frame 412, thereby improving the cleaning effect of ice and snow layer on various positions of the antenna frame 412 surface. The support side rod 4114 slides down, pushing the main body rod 511 to slide down. The main body rod 511 pushes the side slide plate 512 to the right through the pull rod 515, and moves the vertical scraper 516 to the inner wall above the top frame 3 through the first slot 514 on the surface. At this time, as the main body rod 511 slides down, the vertical slide plate 5111 follows the main body rod 511 to slide down under the action of the spring, thereby driving the horizontal scraper 517 to retract to the inside of the top frame 3 through the second slot 5113. At the same time, when the support side rod 4114 slides to the bottom, the main body... The locking block 518 at the bottom of rod 511 contacts the inclined surface of the limiting rod 519. The limiting rod 519 extends into the locking block 518, thereby limiting the main rod 511. When the surface of the antenna frame 412 is covered with ice and snow, and the top frame 3 has finished retracting the antenna frame 412, the side locking rod 5110 pushes the limiting rod 519 to slide away from the antenna frame 412, thereby releasing the limitation on the main rod 511. The main rod 511 slides upward under the action of the spring, thereby driving the transverse locking shaft 5112 to slide upward. At this time, the transverse locking shaft 5112 pushes the transverse scraper 517 out of the interior of the top frame 3 through the second locking groove 5113 on the surface, thereby scraping away the snow on the top of the antenna frame 412. During the upward sliding of the main rod 511...The main rod 511, via the pull rod 515, drives the side sliding plate 512 to slide closer to the antenna frame 412, and through the first slot 514, drives the lifting slot 416 to slide from top to bottom, thereby scraping away the snow accumulated on the slope of the antenna frame 412. Since the antenna frame 412 has already been vibrated and ice-breaking by the rubber hammer 419 during the retraction process, the scraping action of the axial rod 417 and the lifting slot 416, through vibration followed by scraping, effectively reduces the adhesion between the ice and snow and the structural surface, minimizing surface damage during scraping and preventing residual snow or ice from remaining on the surface of the antenna frame 412, thus improving cleaning efficiency.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
