Abstract

This invention provides a novel gateway station, belonging to the field of communication technology. The invention features arc-shaped slide rails with sliders on both sides of the arc-shaped bracket of the X-axis mechanism of the antenna assembly, with the sliders mounted on the antenna base. Simultaneously, an arc-shaped rack is coaxially mounted on the arc-shaped bracket and meshes with a gear on the X-axis driver. This allows the X-axis mechanism to bear weight through the cooperation of the sliders and arc-shaped slide rails, while the drive is achieved through the meshing of the arc-shaped rack and gear.

Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a novel gateway station. Background Technology

[0002] As an important component of satellite communication systems, gateway stations are key structures for ensuring communication. Therefore, improving the performance of gateway stations has become a focus of industry research.

[0003] Currently, existing gateway stations on the market include a radio frequency subsystem consisting of antenna components, filter components, amplifiers, and frequency converters, and a baseband subsystem consisting of satellite modems, network routing equipment, security systems, and web accelerators. In use, they receive satellite signals through antennas and downconvert them to intermediate frequency, or upconvert baseband signals to radio frequency and then transmit them to satellites, thus meeting the signal transmission requirements between ground antennas and satellites.

[0004] Furthermore, the antenna mounts used in existing gateway stations are typically like the XY-axis antenna mount disclosed in patent CN102820537A. In this mount, the X-axis is mounted on a base, the Y-axis mechanism is mounted on the X-axis mechanism, and the roller bracket of the X-axis mechanism is fixed to the base. An arc-shaped raceway is mounted on the roller bracket. In this case, the inner and outer arc surfaces of the arc-shaped raceway are smooth raceways on both sides, and a gear is machined into the middle of the outer arc surface. Multiple pairs of correspondingly positioned pressing rollers are mounted on the roller bracket to press against the smooth raceways on both sides of the inner and outer arc surfaces of the arc-shaped raceway. Additionally, multiple pairs of guide rollers are provided on the left and right sides of the arc-shaped raceway to prevent lateral swaying, and these guide rollers are mounted on the roller bracket. Furthermore, the X-axis servo motor of the X-axis mechanism drives the arc-shaped gear on the back of the arc-shaped raceway via an X-axis reducer. In operation, the X-axis servo motor drives the arc gear via the X-axis reducer, causing the arc raceway to rotate under the action of the clamping rollers and guide rollers, thereby adjusting the X-axis angle of the antenna. Although the above structure can meet the normal X-axis operation requirements, the smooth raceways on both sides of the arc raceway are clamped by corresponding upper and lower clamping rollers and prevented from swaying by guide rollers. This results in the lower clamping roller bearing a relatively large load during use, which can easily lead to excessive clearance after wear. Therefore, lubrication needs to be added to the clamping roller. However, when the clamping roller rotates directly, some lubricating grease will rotate with the clamping roller, constantly exposed to the outside environment and easily thrown out, resulting in impurities and insufficient lubrication, affecting the lubrication effect and thus deteriorating the performance of the gateway station. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, a novel signal station is provided. This station utilizes the cooperation of sliders and slide rails to support the X-axis mechanism. Each slider is equipped with an oil inlet. The movement requirements of the X-axis mechanism are met by the sliding of the slider relative to the slide rail. The lubricating grease located between the slider and the slide rail is not directly exposed to the outside environment, preventing impurities from mixing in or being thrown out, thus maintaining lubrication and ensuring the effective use of the signal station.

[0006] The specific technical solution is as follows: A novel gateway station includes an antenna assembly and a control assembly. The control assembly is mounted on the antenna structure. The antenna assembly includes an antenna surface, a feed hood, an X / Y antenna mount, and an antenna base. The control assembly includes transmit / transmit channels and tracking equipment, in-line telemetry and control equipment, station management equipment, a base station terminal, a time and frequency device, and a power supply unit. The X / Y antenna mount includes an X-axis mechanism and a Y-axis mechanism. The X-axis mechanism is mounted on the antenna base, and the Y-axis mechanism is mounted on the X-axis mechanism. The antenna surface is mounted on the Y-axis mechanism. The X-axis mechanism includes a load-bearing part and an X-axis drive part. The load-bearing part includes an arc-shaped bracket, an arc-shaped slide rail, and a slider. The device has several sliders, which are divided into two groups and respectively set on both sides of the arc-shaped bracket. The sliders in the same group are arranged along an arc and concentric with the center of the arc-shaped bracket. Both sides of the arc-shaped bracket are provided with coaxially arranged arc-shaped slide rails. Each arc-shaped slide rail corresponds to a group of sliders. The sliders in the same group are slidably set on the corresponding slide rails. The sliders are all mounted on the antenna base. The X-axis drive unit includes an arc-shaped rack, a gear, and an X-axis driver. The X-axis driver is mounted on the antenna base and a gear is mounted on its drive shaft. The arc-shaped rack is coaxially mounted on the arc-shaped bracket and meshes with the gear. Furthermore, each slider and its corresponding arc-shaped slide rail are provided with lubricating grease, which is located in the slide cavity of the slider. Each slider also has an oil filling port that is connected to the slide cavity of the slider.

[0007] In the aforementioned novel gateway station, the slider is a ball-bearing arc-shaped guide rail slider.

[0008] In the aforementioned novel signal station, each slider has an oil injection nozzle installed on its oil injection port.

[0009] The aforementioned novel gateway station also includes quick-change baffles. Both ends of the arc-shaped support are equipped with quick-change baffles, which are detachably connected to the arc-shaped support. Furthermore, the two sides of the quick-change baffles extend to the ends of two arc-shaped slide rails, and each arc-shaped slide rail corresponds to two sliders, which are arranged at intervals.

[0010] In the aforementioned novel gateway station, the Y-axis mechanism includes a rotating frame, a rotating shaft, and a Y-axis driver. The two ends of the arc-shaped support are each equipped with a rotating shaft, which are coaxially arranged and both face the inner side of the arc-shaped support. The rotating frame is installed inside the arc-shaped support, and its two ends are rotatably mounted on the corresponding rotating shafts. The Y-axis driver is installed on the rotating frame and is poweredly connected to one of the rotating shafts.

[0011] In the aforementioned novel gateway station, the antenna base includes a base body, a base, and a support base. The base body is a planar frame structure, with an upwardly protruding base in the middle of the base body. The support base is mounted on the base, and the sliders that are slidably mounted on the arc-shaped slide rail are all installed on the support base.

[0012] In the aforementioned novel gateway station, a support frame is also provided on the antenna base. The support frame is fixed on the antenna base and sleeved on the outside of the X / Y axis antenna base. All control components are installed on the support frame. An outer cover is also provided on the support frame, which covers the antenna components and control components.

[0013] In the aforementioned novel gateway station, the bottom of the base is provided with two support plates, which are arranged parallel to each other and spaced apart. Furthermore, each support plate has a slot along its length at its bottom.

[0014] In the aforementioned novel gateway station, the bottom of the antenna base is provided with several adjustable support feet.

[0015] In the aforementioned novel gateway station, both the X-axis mechanism and the Y-axis mechanism further include encoders. The input shaft of the encoder of the X-axis mechanism is poweredly connected to the drive shaft of the X-axis driver. The encoder of the Y-axis mechanism is mounted on a rotating frame and its input shaft is connected to a rotating shaft powered by the Y-axis driver. Furthermore, the input shaft of the encoder of the Y-axis mechanism and the rotating shaft powered by the Y-axis driver are arranged coaxially.

[0016] The positive effects of the above technical solution are: The aforementioned novel gateway station, by providing coaxially arranged arc-shaped slide rails on both sides of the arc-shaped bracket of the X-axis mechanism of the X / Y antenna mount, and sliding sliders on each arc-shaped slide rail, with the sliders mounted on the antenna base, also features an arc-shaped rack coaxially mounted on the arc-shaped bracket. Furthermore, a gear meshing with the arc-shaped rack is mounted on the drive shaft of the X-axis driver, allowing the weight of the arc-shaped bracket to be supported by the sliders. The rotation of the arc-shaped bracket is achieved through the cooperation of the arc-shaped rack and gears. This separates the load-bearing and driving functions of the X-axis mechanism, reducing the problem of wear and tear affecting performance. Additionally, each slider's cavity is filled with lubricating grease, and each slider has an oil inlet, ensuring lubrication between the slider and the arc-shaped slide rail. This satisfies lubrication requirements while preventing the entry or ejection of foreign matter due to external exposure. The oil inlet allows for timely replenishment of lubricating grease, further reducing friction, minimizing wear, extending service life, and improving overall performance.

[0019] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 4 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0020] Figure 1 This is a structural diagram of an embodiment of a novel gateway station according to the present invention; Figure 2 This is a structural diagram of the X-axis mechanism of a novel gateway station according to this utility model. Figure 1 and Figure 2 As shown, the novel gateway station provided in this embodiment includes an antenna assembly 1 and a control assembly. The control assembly is installed on the antenna structure to control the operation of the antenna assembly 1, thereby meeting communication requirements. The antenna assembly 1 further includes an antenna surface 11, a feed, an X / Y antenna mount 12, and an antenna base 13. The X / Y antenna mount 12 is installed on the antenna base 13, the antenna surface 11 is installed on the X / Y antenna mount 12, and finally the feed is installed on the antenna surface 11, forming the basic structure that enables the gateway station to move. Furthermore, the control assembly includes transmit / transmit channels and tracking equipment, in-line telemetry and control equipment, station management equipment, base station terminals, time and frequency equipment, and power supply units. Since these structures are all conventional configurations in the satellite communication field and are widely used, their specific structural connections and operating principles will not be described in detail here.

[0021] Specifically, the X / Y antenna mount 12 includes an X-axis mechanism 121 and a Y-axis mechanism 122. The X-axis mechanism 121 is mounted on the antenna base 13, the Y-axis mechanism 122 is mounted on the X-axis mechanism 121, and the antenna surface 11 is mounted on the Y-axis mechanism 122. Through the actions of the X-axis mechanism 121 and the Y-axis mechanism 122, the antenna surface 11 is deflected in the X-axis and Y-axis directions, thereby meeting the usage requirements of following satellite movement. Furthermore, the X-axis mechanism 121 includes a load-bearing part and an X-axis drive part. The load-bearing part includes an arc-shaped bracket 1211, an arc-shaped slide rail 1212, and sliders 1213. Several sliders 1213 are provided, divided into two groups and respectively located on both sides of the arc-shaped bracket 1211. The sliders 1213 in the same group are arranged along an arc and concentric with the center of the arc-shaped bracket 1211, allowing the arc of the group of sliders 1213 to accommodate the rotation of the arc-shaped bracket 1211. Furthermore, coaxially arranged arc-shaped slide rails 1212 are provided on both sides of the arc-shaped bracket 1211, enabling the installation of the arc-shaped slide rails 1212 on the arc-shaped bracket 1211. Each arc-shaped slide rail 1212 corresponds to a group of sliders 1213, and the sliders 1213 in the same group are slidably mounted on the corresponding slide rail, allowing for subsequent relative sliding between the sliders 1213 and the slide rail. Furthermore, the sliders 1213 are all mounted on the antenna base 13, ensuring stable installation of the sliders 1213. This allows the slide rail to rotate relative to the antenna base 13, enabling the arc-shaped bracket 1211 to rotate in the X-axis direction, thus meeting the angle adjustment requirements. The X-axis drive unit includes an arc-shaped rack 1214, a gear 1215, and an X-axis driver 1216. The X-axis driver 1216 is mounted on the antenna base 13, and the gear 1215 is mounted on its drive shaft. The arc-shaped rack 1214 is coaxially mounted on the arc-shaped bracket 1211 and meshes with the gear 1215. When the X-axis driver 1216 operates, the gear 1215 and the arc-shaped rack 1214 provide power for the rotation of the arc-shaped bracket 1211, thereby meeting the angle adjustment requirements of the gateway station.

[0022] Specifically, each slider 1213 and its corresponding arc-shaped slide rail 1212 are provided with lubricating grease. This lubrication reduces friction between the two, resulting in less wear and a longer service life. Furthermore, the lubricating grease is located within the slide cavity of the slider 1213, preventing direct exposure to the outside environment that could lead to impurities or dislodgement during operation, thus ensuring effective lubrication and improving the performance of the signal station. Additionally, each slider 1213 is equipped with an oil inlet 12131, which communicates with the slide cavity of the slider 1213. This allows for direct addition of lubricating grease when needed, making operation more convenient and the structural design more rational.

[0023] More specifically, the slider 1213 is a ball-bearing arc-shaped guide rail slider 1213. This not only ensures that the shape of the slider 1213 conforms to the shape of the arc-shaped slide rail 1212, accommodating the sliding of the arc-shaped slide rail relative to the slider 1213 and preventing jamming, but also ensures that the distance between all parts of the sliding cavity of the slider 1213 and the corresponding arc-shaped slide rail 1212 is consistent. This facilitates stable contact between the balls inside the slider 1213 and the outer wall of the arc-shaped slide rail 1212, resulting in better and more stable support. Furthermore, the balls inside the slider 1213 can further reduce the friction between the slider 1213 and the arc-shaped slide rail 1212, reducing wear and extending service life.

[0024] More specifically, each slider 1213 has an oil filling port 12131 equipped with an oil filling nozzle. Preferably, the oil filling nozzle is a side-tilting oil filling nozzle, which facilitates oil filling operation from the side of the slider 1213. This allows operators to manually add lubricating grease directly through the oil filling nozzle, or to remotely fill the pipe through the oil filling nozzle, meeting different usage needs and making the structural design more reasonable.

[0025] More specifically, quick-change baffles 1217 are provided at both ends of the arc-shaped bracket 1211. The quick-change baffles 1217 are detachably connected to the arc-shaped bracket 1211. Furthermore, the two sides of the quick-change baffles 1217 extend to the two ends of the two arc-shaped slide rails 1212 respectively. The quick-change baffles 1217 prevent the slider 1213 from slipping off the arc-shaped slide rails 1212. They also provide the condition that the damaged slider 1213 can be removed and replaced separately after the quick-change baffles 1217 are removed if the slider 1213 is damaged in the future. At this time, each arc-shaped slide rail 1212 corresponds to two sliders 1213, and the two sliders 1213 are arranged at intervals. That is, there are a total of four sliders 1213 supporting the two sides of the arc-shaped bracket 1211. At this time, if one of the sliders 1213 is damaged, the arc-shaped bracket 1211 still has three sliders 1213 supporting it, which can still maintain the stable operation of the arc-shaped bracket 1211. When replacing the damaged slider 1213, the quick-change baffle 1217 can be removed, and the damaged slider 1213 can be slid along the arc-shaped slide rail 1212 to the end and then detached. At the same time, the new slider 1213 can be installed from the end of the arc-shaped slide rail 1212 onto the arc-shaped slide rail 1212, which meets the use requirement of replacing the slider 1213 individually without the need for overall disassembly and replacement. Furthermore, since the other three sliders 1213 do not move at all when the damaged slider 1213 is disassembled and installed separately, and there is no relative movement between them and the arc-shaped slide rail 1212, no further adjustments are needed after replacing slider 1213, and it can be used directly, which facilitates maintenance and repair. It is worth noting that the quick-change baffle 1217 is connected to the end of the arc-shaped bracket 1211 by screws, which meets the disassembly and assembly requirements of the quick-change baffle 1217 on the arc-shaped bracket 1211.

[0026] Figure 3 This is a structural diagram of the Y-axis mechanism of a novel gateway station according to this utility model. Figures 1 to 3 As shown, the Y-axis mechanism 122 of the X / Y antenna mount 12 includes a rotating frame 1221, a rotating shaft 1222, and a Y-axis driver 1223. Rotating shafts 1222 are mounted on both ends of the arc-shaped support 1211. The two rotating shafts 1222 are coaxially arranged and both face inwards towards the arc-shaped support 1211, forming a rotational support structure at both ends of the inner side of the arc-shaped support 1211. Simultaneously, the rotating frame 1221 is installed inside the arc-shaped support 1211, with both ends rotatably mounted on the corresponding rotating shafts 1222. This allows for the rotating installation of the rotating frame 1221 within the arc-shaped support 1211, fully utilizing the internal space of the arc-shaped support 1211, reducing the overall volume of the gateway station, and also meeting the rotational requirements of the rotating frame 1221 on the X-axis mechanism 121. Furthermore, the Y-axis driver 1223 is mounted on the rotating frame 1221 and poweredly connected to a rotating shaft 1222, so that when the Y-axis driver 1223 is activated, it can drive the rotating frame 1221 to rotate relative to the rotating shaft 1222, thereby meeting the Y-axis angle adjustment requirements. It is worth noting that the antenna surface 11 is mounted on the rotating frame 1221, allowing the antenna surface 11 to achieve both X-axis angle adjustment under the action of the X-axis mechanism 121 and Y-axis angle adjustment under the action of the Y-axis mechanism 122, thus meeting the requirements for following satellite movement. Furthermore, a fixed gear 1215 is mounted on the rotating shaft 1222, which is powered by the Y-axis driver 1223, and a follower gear 1215 is provided on the drive shaft of the Y-axis driver 1223. The follower gear 1215 and the fixed gear 1215 mesh, enabling relative rotation of the follower gear 1215 and the fixed gear 1215 when the Y-axis driver 1223 operates, ensuring rotation of the rotating frame 1221 while the rotating shaft 1222 remains stationary. Preferably, the Y-axis driver 1223 is equipped with a gearbox, including but not limited to a geared gearbox, which reduces speed to provide greater torque, ensuring smooth and stable rotation of the rotating frame 1221. In addition, the rotating frame 1221 also includes an expansion frame 1224. The expansion frame 1224 is set inside the arc-shaped bracket 1211 and is connected to the rotating frame 1221. The expansion frame 1224 can make full use of the internal space of the arc-shaped bracket 1211 to expand the installation space of the rotating frame 1221, so that the high-frequency box and other structures of the control components have enough space to be installed, realizing the rational use of space and further reducing the volume of the gateway station while ensuring normal use.

[0027] More specifically, the antenna base 13 includes a base body 131, a base 132, and a support base 133. The base body 131 is a planar frame structure, with an upwardly protruding base 132 in the middle. The support base 133 is mounted on the base 132, and sliders 1213, which are slidably mounted on arc-shaped slide rails 1212, are all installed on the support base 133. Thus, the base 132 and the support base 133 achieve stable mounting of the X-axis mechanism 121 on the base body 131. Preferably, the base body 131 is a large-plane annular frame, providing a larger contact area with the ground, allowing the gateway station to be placed more stably on the ground, a base station, or a vehicle. It is worth noting that the support base 133 has a structure with a through groove in the middle. The two sets of sliders 1213 corresponding to the two arc-shaped slide rails 1212 are respectively set on the two side walls of the through groove of the support base 133. At this time, the arc-shaped bracket 1211 is located in the through groove. That is, the support base 133 with the through groove can support the two sides of the arc-shaped bracket 1211 respectively, ensuring stable support. At the same time, it can also make part of the structure of the arc-shaped bracket 1211 fit in the through groove, making more reasonable use of space, which is conducive to the miniaturization of the overall structure and makes the structure more compact.

[0028] More specifically, the antenna base 13 is also equipped with a support frame 134. The support frame 134 is fixed to the antenna base 13 and sleeved on the outside of the X / Y axis antenna mount. All control components are mounted on the support frame 134. This means that the control components used for control are all mounted on the antenna base 13 via the support frame 134, satisfying the integrated structural layout of the gateway station. This eliminates the need for wiring and debugging during subsequent use; it can be used simply by laying it flat, making it more convenient. In addition, the support frame 134 is also equipped with an outer cover, which covers the antenna assembly 1 and the control components, providing external protection for them and improving safety. It is worth noting that the outer cover has a spherical structure, while the support frame 134 has a circular structure. The bottom of the outer cover has an opening, allowing it to be easily installed over the antenna assembly 1 and the control components. The opening of the outer cover is connected to the support frame 134. Preferably, the outer cover and the support frame 134 are connected by screws, allowing for detachable installation of the outer cover on the support frame 134. In addition, the support frame 134 is installed on the base 131, and the outer edge of the support frame 134 is within the coverage area of ​​the base 131, which avoids the problem of the support frame 134 exceeding the base 131 and occupying extra space, and the structural design is more reasonable.

[0029] Figure 4 This is a structural diagram of the base of a novel gateway station according to this utility model. Figure 1 and Figure 4As shown, the bottom of the base 131 is provided with two trays 1311. The two trays 1311 are arranged in parallel and spaced apart. Each tray 1311 has a slot 13111 at its bottom along its length. That is, the trays 1311 form two structures with slots 13111 at the bottom of the base 131. This allows the customs station to be lifted by inserting tools such as forklifts into the slots 13111 of the two trays 1311 when it is being transferred. The structure is simple and facilitates the transfer of the customs station, making the customs station more convenient.

[0030] More specifically, the bottom of the antenna base 13 is also provided with several adjustable support feet 135. Preferably, the adjustable support feet 135 are located at the bottom of the base 131, that is, the base 131 is supported by adjusting the support feet 135, and the base 131 can be leveled by adjusting the extension and retraction of the support feet 135, meeting the adjustment needs in different scenarios. It is worth noting that since the adjustable support feet 135 are widely used in the market and belong to the application of existing products, the specific structure of the adjustable support feet 135 will not be described in detail here.

[0031] More specifically, both the X-axis mechanism 121 and the Y-axis mechanism 122 include encoders. The input shaft of the encoder in the X-axis mechanism 121 is poweredly connected to the drive shaft of the X-axis driver, enabling the recording of the rotational speed and number of revolutions of the X-axis driver 1216, facilitating the calculation and determination of the rotational angular velocity and rotational angle of the arc-shaped bracket 1211. Similarly, the encoder in the Y-axis mechanism 122 is mounted on the rotating frame 1221, and its input shaft is connected to a rotating shaft 1222 powered by the Y-axis driver 1223. Furthermore, the input shaft of the encoder in the Y-axis mechanism 122 and the rotating shaft 1222 powered by the Y-axis driver 1223 are arranged coaxially, allowing the encoder to record the rotational speed and number of revolutions of the rotating frame 1221 as it rotates with the rotating frame 1221, facilitating the calculation and determination of the rotational angular velocity and rotational angle of the rotating frame 1221.

[0032] The novel gateway station provided in this embodiment includes an antenna assembly 1 and a control assembly. Coaxially arranged arc-shaped slide rails 1212 are provided on both sides of the arc-shaped bracket 1211 of the X-axis mechanism 121 of the antenna assembly 1. A slider 1213 is provided on each arc-shaped slide rail 1212, and the sliders 1213 are mounted on the antenna base 13. Simultaneously, an arc-shaped rack 1214 is coaxially provided on the arc-shaped bracket 1211 and meshes with the gear 1215 on the X-axis driver 1216. That is, the load-bearing capacity of the X-axis mechanism 121 is achieved through the cooperation of the sliders 1213 and the arc-shaped slide rails 1212, and the drive is achieved through… The engagement of the arc-shaped rack 1214 and gear 1215 ensures that the load-bearing and driving functions of the X-axis mechanism 121 are arranged separately, reducing the risk of wear, extending service life, and improving performance. At the same time, lubricating grease is provided between the slider 1213 and the arc-shaped slide rail 1212, and the slider 1213 has an oil filling port 12131 communicating with its slide cavity. The lubricating grease further reduces wear and prevents wear from reducing stability and accuracy. In addition, lubricating grease can be added in time through the oil filling port 12131 to ensure the sustainability of lubrication, further extending service life and improving performance.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
