Technical Field

[0001] This utility model belongs to the field of diaphragm circular polarizer adjustment technology, specifically an adjustable diaphragm circular polarizer device. Background Technology

[0002] With the development of science and technology, satellite communication technology has been widely used. Polarizers are a commonly used device in the field of satellite communication technology. They are devices that control the polarization direction of the antenna feed system. Polarizers are used to select the polarization form that is consistent with the satellite television signal and suppress other forms of polarization waves in order to achieve polarization matching and realize optimal reception.

[0003] Existing diaphragm-type circular polarizers contain multiple diaphragms of varying heights and widths inside the polarizer. These diaphragms are in close contact with each other, partially dividing the internal space of the polarizer into two parts. However, the traditional diaphragm-type circular polarizer structure is relatively fixed and lacks flexible adjustable components and corresponding functions.

[0004] Therefore, this utility model provides an adjustable diaphragm circular polarizer device. Utility Model Content

The driving gears are respectively positioned to correspond to the meshing blocks; limit rods are fixed to the inner sidewall of the adjusting box, and multiple limit rods are positioned to correspond to the positions of the adjusting partitions; a limit slide is provided at the bottom of the adjusting partition, and the limit slide is sized to correspond to the limit rods; this step achieves the adjustability of multiple adjusting partitions by setting a drive motor, meshing blocks, rotating rods, and driving gears, improving the flexibility of the partition-type circular polarizer and helping to solve the problem of the relatively fixed structure of traditional circular polarizers. By setting limit rods to limit multiple adjusting partitions, it is helpful to avoid the adjusting partitions from tilting during movement, thus enhancing the stability of the device.

[0007] Preferably, a limiting strip is fixed to the side wall of the adjusting partition; a first limiting groove is formed on the side wall of the adjusting partition away from the limiting strip; and a second limiting groove is formed on the side wall of the adjusting box. This step restricts the movement posture of multiple adjusting partitions by setting the limiting strip, the first limiting groove, and the second limiting groove, thereby preventing the adjusting partitions from rotating or tilting during movement, enhancing the stability and durability of the partition circular polarizer, which is beneficial to extending the service life of the device and reducing maintenance needs and costs.

[0008] Preferably, a fixing plate is fixedly connected to the inner side wall of the adjusting box, and multiple fixing plates are arranged corresponding to the position of the rotating rod; a fixing block is fixedly connected to the side wall of the fixing plate, and multiple fixing blocks are respectively arranged corresponding to the position of the rotating rod; this step supports the rotating rod by setting the fixing plate and fixing block, and restricts the movement posture of the rotating rod, preventing the rotating rod from tilting during operation, improving the stability and durability of the partition-type circular polarizer, helping to reduce the maintenance requirements of the device, maintaining the sensitive and controllable height of multiple adjusting partitions, and extending the service life.

[0009] Preferably, a load-bearing spring is fixedly connected inside the adjustment box, and multiple load-bearing springs are positioned corresponding to the limit rods; the ends of the multiple load-bearing springs away from the adjustment box are respectively fixedly connected to the bottom of the adjustment partition; this step, by setting load-bearing springs to connect the adjustment box and the adjustment partition, provides support for the bottom of the multiple adjustment partitions, which helps to solve the problem of the adjustment partitions sliding down due to their own weight, and enhances the stability and practicality of the partition-type circular polarization.

[0010] Preferably, the fixed block is provided with a graphite sleeve inside, and the size of the graphite sleeve corresponds to that of the rotating rod; the rotating rod and the graphite sleeve are rotatably connected; this step, by providing a graphite sleeve inside the fixed block to support and lubricate the rotating rod, avoids mutual wear between the fixed block and the rotating rod, improves the durability of the partition-type circular polarizer, helps to reduce the maintenance requirements of the circular polarizer, and enhances its stability.

[0011] Preferably, the two ends of the rotating rod are rotatably connected to limit blocks, and the two limit blocks are respectively fixed to the side wall of the regulating box. This step limits the position of the rotating rod by setting limit blocks, which prevents it from falling off during operation, enhances the stability of the circular polarizer, helps to prevent the device components from loosening, and extends the service life of the device.

[0012] Preferably, the meshing block and the drive gear are made of stainless steel. This step, by using stainless steel for the meshing block and the drive gear, keeps their surfaces smooth and maintains tight meshing, which helps to extend the service life of the device and reduce maintenance needs and difficulties.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown, an adjustable partition circular polarizer device according to an embodiment of the present invention includes an adjustment box 1, with a partition plate 4 fixedly connected inside the adjustment box 1; an adjustment partition 3 is provided inside the adjustment box 1, and multiple adjustment partitions 3 are arranged in parallel; a meshing block 5 is provided at the bottom of the adjustment partition 3, and multiple meshing blocks 5 are arranged correspondingly; a drive motor 2 is fixedly connected to the side wall of the adjustment box 1, and multiple drive motors 2 are arranged correspondingly; a rotating rod 6 is fixedly connected to the output end of the drive motor 2, and the rotating rod 6 is rotatably connected inside the adjustment box 1; the rotating rod 6... A drive gear 7 is fixedly connected to the side wall, and multiple drive gears 7 are respectively set to the positions of meshing blocks 5; a limit rod 9 is fixedly connected to the inner side wall of the adjusting box 1, and multiple limit rods 9 are set to the positions of adjusting partitions 3; a limit slide is opened at the bottom of the adjusting partition 3, and the limit slide is set to the size of the limit rod 9; during operation, the operator can control the height of multiple adjusting partitions 3 separately by driving the drive motor 2. During the process, whenever any drive motor 2 is driven, the output end of the drive motor 2 is fixedly connected to the drive motor 2. The rotating rod 6 will rotate, driving the drive gear 7 fixed to the side wall of the rotating rod 6 to rotate synchronously. As the drive gear 7 rotates, the corresponding meshing block 5 meshes with the drive gear 7, and the corresponding adjusting partition 3 is limited by the partition plate 4 and the limiting rod 9. The adjusting partition 3 will move vertically with the drive of the drive motor 2. The operator can control multiple drive motors 2 separately until the multiple adjusting partitions 3 inside the adjusting box 1 are adjusted to the predetermined height. The position and size of the limiting slide corresponding to the limiting rod 9 are set. Whenever the adjusting partition 3 moves vertically, the limiting rod 9 always contacts the side wall of the limiting slide. This step realizes the adjustability of multiple adjusting partitions 3 by setting the drive motor 2, meshing block 5, rotating rod 6, and drive gear 7, which improves the flexibility of the partition-type circular polarizer and helps to solve the problem of the relatively fixed structure of the traditional circular polarizer. By setting the limiting rod 9 to limit the multiple adjusting partitions 3, it is helpful to avoid the adjusting partitions 3 from tilting during the movement, thus enhancing the stability of the device.

[0025] like Figure 4As shown, a limiting strip 10 is fixedly connected to the side wall of the adjusting partition 3; a first limiting groove 13 is provided on the side wall of the adjusting partition 3 away from the limiting strip 10; a second limiting groove 15 is provided on the side wall of the adjusting box 1; during operation, the limiting strip 10 of adjacent adjusting partitions 3 is correspondingly arranged with the first limiting groove 13, and the second limiting groove 15 is correspondingly arranged with the limiting strip 10 inside it. Whenever an adjusting partition 3 moves to the maximum value of a predetermined position, the top of the limiting strip 10 fixed to its side wall will contact the first limiting groove provided on the side wall of the adjacent adjusting partition 3. At the top of the slide groove 13, and because the adjacent limiting strips 10, the first limiting slide groove 13, and the second limiting slide groove 15 are correspondingly arranged, the surface of the partition assembly composed of multiple adjusting partitions 3 will remain flat. This step restricts the movement posture of the multiple adjusting partitions 3 by setting the limiting strips 10, the first limiting slide groove 13, and the second limiting slide groove 15, thereby preventing the adjusting partitions 3 from rotating or tilting during movement, enhancing the stability and durability of the partition circular polarizer, which is beneficial to extending the service life of the device and reducing maintenance needs and costs.

[0026] like Figure 2 As shown, a fixing plate 11 is fixedly connected to the inner wall of the regulating box 1, and multiple fixing plates 11 are arranged corresponding to the position of the rotating rod 6; a fixing block 12 is fixedly connected to the side wall of the fixing plate 11, and multiple fixing blocks 12 are respectively arranged corresponding to the position of the rotating rod 6; during operation, the support assembly consisting of the fixing plate 11 and the fixing block 12, which is fixed to the inner wall of the regulating box 1, can provide support force for the rotating rod 6. At the same time, the fixing plate 11 and the fixing block 12 can restrict the working posture of the rotating rod 6 through contact with the rotating rod 6, so as to prevent it from tilting during operation. This step, by setting the fixing plate 11 and the fixing block 12 to support the rotating rod 6 and restrict the movement posture of the rotating rod 6, prevents the rotating rod 6 from tilting during operation, improves the stability and durability of the partition-type circular polarizer, helps to reduce the maintenance requirements of the device, maintains the sensitive controllability of the height of multiple regulating partitions 3, and extends the service life.

[0027] like Figure 2 and Figure 3As shown, load-bearing springs 14 are fixedly connected inside the regulating box 1, and multiple load-bearing springs 14 are positioned corresponding to the limit rod 9. The ends of multiple load-bearing springs 14 away from the regulating box 1 are fixedly connected to the bottom of the regulating partition 3. During operation, multiple load-bearing springs 14 fixed between the regulating box 1 and the regulating partition 3 are always in a compressed state. Because the load-bearing springs 14 are in a compressed state, multiple load-bearing springs 14 can continuously provide stress to the corresponding regulating partition 3. The dimensions of multiple load-bearing springs 14 are set to correspond to the corresponding regulating partition 3. This step, by setting load-bearing springs 14 to connect the regulating box 1 and the regulating partition 3, provides support for the bottom of multiple regulating partitions 3, which helps to solve the problem of the regulating partition 3 sliding down due to its own weight, and enhances the stability and practicality of the partition-type circular polarization.

[0028] like Figure 2 As shown, a graphite sleeve is provided inside the fixing block 12, and the size of the graphite sleeve corresponds to that of the rotating rod 6. The rotating rod 6 and the graphite sleeve are rotatably connected. During operation, the graphite sleeve inside the fixing block 12 lubricates the rotating rod 6 through its contact with the rotating rod 6. During the process, whenever the rotating rod 6 rotates under the drive of the drive motor 2, the part of the rotating rod 6 in contact with the graphite sleeve will rub against it. As the friction progresses, graphite powder will gradually coat the surface of the rotating rod 6, ultimately achieving lubrication of the rotating rod 6. This step, by providing support and lubrication for the rotating rod 6 through the graphite sleeve inside the fixing block 12, avoids mutual wear between the fixing block 12 and the rotating rod 6, improves the durability of the partition-type circular polarizer, helps reduce the maintenance requirements of the circular polarizer, and enhances its stability.

[0029] like Figure 2 and Figure 3 As shown, the two ends of the rotating rod 6 are rotatably connected to limit blocks 8, and the two limit blocks 8 are respectively fixed to the side wall of the regulating box 1. During operation, the limit blocks 8, which are rotatably connected to the rotating rod 6 and fixed to the side wall of the regulating box 1, can limit the position of the rotating rod 6 by themselves, so as to prevent the rotating rod 6 from shifting or falling off during operation. This step, by setting the limit blocks 8 to limit the position of the rotating rod 6, prevents it from falling off during operation, enhances the stability of the circular polarizer, helps to prevent the device components from loosening, and extends the service life of the device.

[0030] like Figure 2 As shown, the meshing block 5 and the drive gear 7 are made of stainless steel. During operation, the stainless steel meshing block 5 and the drive gear 7 can maintain a smooth surface for a long time. This step, by using stainless steel for the meshing block 5 and the drive gear 7 to maintain the smooth surface of both, and to maintain the tight meshing between them, helps to extend the service life of the device and reduce maintenance needs and maintenance difficulty.

[0031] During operation, the operator can control the height of multiple adjustable partitions 3 individually by driving the drive motor 2. Whenever any drive motor 2 is activated, the rotating rod 6 fixed to the output end of the drive motor 2 will rotate, causing the drive gear 7 fixed to the side wall of the rotating rod 6 to rotate synchronously. As the drive gear 7 rotates, the corresponding meshing block 5 meshes with the drive gear 7, and the corresponding adjustable partition 3 is limited by the partition plate 4 and the limiting rod 9. The adjustable partition 3 will then move vertically as driven by the drive motor 2. The operator can control multiple drive motors 2 individually until the height of multiple partitions inside the adjusting box 1 is adjusted. Adjusting partition 3 to a predetermined height, wherein the position and size of the limiting slide corresponding to the limiting rod 9 are set. Whenever the adjusting partition 3 moves vertically, the limiting rod 9 always contacts the side wall of the limiting slide. The limiting strip 10 of the adjacent adjusting partition 3 is correspondingly set with the first limiting groove 13, and the second limiting groove 15 is correspondingly set with the limiting strip 10 inside it. Whenever an adjusting partition 3 moves to the maximum value of the predetermined position, the top of the limiting strip 10 fixed to its side wall will contact the top of the first limiting groove 13 opened on the side wall of the adjacent adjusting partition 3. At the same time, due to the adjacent limiting strip 10, the first limiting groove 13, and the second limiting groove 15, the limiting rod 9 is always in contact with the side wall of the limiting slide. 5. The surface of the partition assembly, composed of multiple adjusting partitions 3, remains flat and is fixed to the inner wall of the adjusting box 1. The support assembly, composed of fixing plates 11 and fixing blocks 12, provides support for the rotating rod 6. At the same time, the fixing plates 11 and fixing blocks 12 can restrict the working posture of the rotating rod 6 through contact with it, preventing it from tilting during operation. Multiple load-bearing springs 14, fixed between the adjusting box 1 and the adjusting partitions 3, are always in a compressed state. Because the load-bearing springs 14 are in a compressed state, they can continuously provide stress to the corresponding adjusting partitions 3. The dimensions of the multiple load-bearing springs 14 correspond to the corresponding... The adjusting baffle 3 is set, and the graphite sleeve set inside the fixed block 12 can lubricate the rotating rod 6 through its contact with the rotating rod 6. During the process, whenever the rotating rod 6 rotates under the drive of the drive motor 2, the part of the rotating rod 6 in contact with the graphite sleeve will rub against it. As the friction proceeds, graphite powder will gradually coat the surface of the rotating rod 6, and finally lubricate the rotating rod 6. The limiting block 8, which is rotatably connected to the rotating rod 6 and is fixed to the side wall of the adjusting box 1, can limit the position of the rotating rod 6 by itself, so as to prevent the rotating rod 6 from shifting or falling off during the operation. The meshing block 5 and the drive gear 7, made of stainless steel, can keep the surface smooth for a long time.
