Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for jamming equipment, specifically a highly stable polarization jamming device. Background Technology

[0002] Polarization jamming equipment is a type of electronic countermeasures technology that manipulates the polarization characteristics of electromagnetic waves. Its core principle is to reduce the detection effectiveness of enemy radar or communication systems by utilizing changes in the polarization direction of electromagnetic waves. This equipment destroys the signal recognition capability of the enemy's receiving system by emitting electromagnetic waves orthogonal to the polarization direction of the target. In traditional electronic warfare, it is often used to reduce the detection accuracy of enemy radar, disrupt target identification systems, or cover the penetration of friendly combat units.

[0003] However, traditional polarization interference devices face many inconveniences and instability issues in actual use. On the one hand, during device movement, due to the lack of effective buffering and adaptive adjustment mechanisms, they are easily affected by factors such as uneven ground and vibration, leading to loosening and damage of internal components, which in turn affects the normal operation of the device. On the other hand, when the device is placed stably, it is difficult to make precise adjustments to the direction and angle according to actual needs, which cannot meet the specific requirements of polarization interference in different scenarios, thus limiting the application range and effectiveness of the device. Therefore, we propose a highly stable polarization interference device. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: addressing the numerous inconveniences and instability issues faced by polarization interference devices in practical use.

[0005] To address the aforementioned technical problems, this application provides a highly stable polarization interference device, including a mounting frame. An upper plate is located at the lower end of the mounting frame, a connector is located at the lower end of the upper plate, a lower plate is located at the lower end of the connector, and a base plate is located at the lower end of the lower plate. Three casters are fixedly connected to the lower end of the base plate in a circular array. A curtain is fixedly connected to the outer side of the upper plate, and four limiting cylinders are evenly distributed in a circular array on the outer side of the upper plate. Four limiting cylinders are evenly distributed in a circular array, and the lower end of the mounting frame is fixedly connected to four limiting posts in a circular array. The limiting posts and the limiting cylinders are mutually adapted, and the limiting posts are movably connected inside the limiting cylinders.

[0006] In some embodiments, the connector includes a positioning block and a movable column. Positioning blocks are provided at both ends of the movable column. Four connectors are provided and evenly distributed in a circumferential array. The positioning block located at the lower end of the movable column is fixedly connected to one side surface of the lower plate, and the positioning block located at the upper end of the movable column is fixedly connected to one side surface of the upper plate.

[0007] In some embodiments, a cross-shaped rotating component is movably connected between the two ends of the movable column and the positioning block. A linkage bevel gear is fixedly connected to one side surface of the cross-shaped rotating component. A driving bevel gear is movably connected to one side of the linkage bevel gear. A driving gear is fixedly connected to the lower end of the driving bevel gear. One side surface of the driving gear is movably connected to one side surface of the lower plate.

[0008] In some embodiments, the linkage bevel gear and the driving bevel gear mesh with each other, and a linkage rack is movably connected to the outer side of the driving gear. Two linkage racks are provided and are distributed in an alternating manner, with the two linkage racks arranged in upper and lower layers.

[0009] In some embodiments, a guide frame is fixedly connected to one side surface of the lower plate, and two linkage racks are movably disposed inside the guide frame. The outer side of the linkage rack is in contact with the inner wall of the guide frame. A motor is disposed at the lower end of the lower plate, and the output end of the motor is fixedly connected to one side of the drive gear.

[0010] In some embodiments, an adjustment groove is provided on the inner side of the mounting bracket, a mounting plate is provided at the upper end of the adjustment groove, a hollow cylinder is fixedly connected to the lower end of the mounting plate, an adjustment spring is fixedly connected to one side surface of the hollow cylinder, a movable stake is provided at the lower end of the hollow cylinder, and the other end of the adjustment spring is fixedly connected to one side surface of the movable stake.

[0011] In some embodiments, one end of the movable pile is fixedly connected to an arc panel, one side of the arc panel is provided with an adjusting ball, the adjusting ball is disposed inside the adjusting groove, an annular plate is fixedly connected to the inside of the adjusting groove, an adjusting frustum is movably disposed in the middle of the annular plate, the outer side of the adjusting ball is in contact with one side surface of the annular plate, and the outer side of the adjusting ball is in contact with one side surface of the adjusting frustum.

[0012] In some embodiments, three hollow cylinders and three adjusting balls are provided and evenly distributed in a circumferential array, and a connecting plate is fixedly connected between the three hollow cylinders.

[0013] This invention has at least the following beneficial effects:

[0014] This invention utilizes three sets of hollow cylinders, adjusting springs, and movable piles at the lower end of the mounting plate to achieve adaptive adjustment during equipment movement and stable placement. The three hollow cylinders are stabilized by a connecting plate to prevent misalignment and deflection, while simultaneously stabilizing the position of the three adjusting balls, which are evenly distributed in an equilateral triangle shape between the annular plate and the adjusting frustum. When the hollow cylinders drive the arc panel to act on the adjusting balls, the adjusting balls contact the annular plate and the adjusting frustum, adjusting the position of the adjusting frustum within the adjusting groove and stabilizing the relationship between internal components. This effectively buffers vibration and impact, ensuring stable operation of the polarization interference equipment under various working conditions.

[0015] This invention uses a motor to drive a fixed drive gear at the output end and a drive gear set opposite to it to drive synchronously. The drive gear is driven by a linkage rack, and then the linkage bevel gear meshes with the drive bevel gear, so that the cross rotating component can be offset and rotate synchronously in the same direction. The four connecting parts can achieve synchronous rotation and offset in the same direction, thereby driving the upper plate and the upper part of the upper plate to move smoothly and steadily. This meets the requirements of the working direction and angle of the polarization interference device in different scenarios, and improves the applicability and flexibility of the device.

[0016] This invention allows users to choose whether to install the entire mounting frame on the upper plate after the polarization interference device is installed on the mounting plate, using the cooperation between the limiting post and the limiting cylinder. When the entire upper device does not need to be moved or needs to be placed stably, the mounting frame can be placed stably on the upper plate. In other cases, the installation state of the mounting frame can also be flexibly adjusted according to actual needs. The invention fully considers different usage scenarios and user needs, enabling the device to better adapt to various working environments and improving the practicality of the device and user satisfaction.

Detailed Implementation

[0025] 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.

[0026] Example

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This invention provides a technical solution: a highly stable polarization interference device, comprising a mounting frame 1, an upper plate 2 at the lower end of the mounting frame 1, a connector 3 at the lower end of the upper plate 2, a lower plate 4 at the lower end of the connector 3, a base plate 5 at the lower end of the lower plate 4, and three casters 6 evenly distributed in a circular array at the lower end of the base plate 5. A curtain 7 is fixedly connected to the outer side of the upper plate 2, the curtain 7 serving to shield and protect the area between the upper plate 2 and the lower plate 4. Function: A limiting cylinder 9 is provided on the outer side of the upper plate 2. The limiting cylinder 9 is provided with four limiting columns 8 that are evenly distributed in a circular array at the lower end of the mounting frame 1. The limiting columns 8 are provided with four limiting columns 8 that are evenly distributed in a circular array. The limiting columns 8 and the limiting cylinder 9 are mutually adapted to each other. The limiting columns 8 are movably connected to the inside of the limiting cylinder 9. When the upper part of the whole device does not need to be moved or placed stably, the mounting frame 1 and the upper part of the whole are stably placed on the upper end of the upper plate 2 by using the cooperation between the limiting columns 8 and the limiting cylinder 9.

[0028] The connector 3 includes a positioning block 10 and a movable column 11. Positioning blocks 10 are provided at both ends of the movable column 11. There are four connectors 3, which are evenly distributed in a circumferential array. The positioning block 10 located at the lower end of the movable column 11 is fixedly connected to one side surface of the lower plate 4, and the positioning block 10 located at the upper end of the movable column 11 is fixedly connected to one side surface of the upper plate 2.

[0029] A cross-shaped rotating component 12 is movably connected between both ends of the movable column 11 and the positioning block 10. Through the cooperation between the cross-shaped rotating component 12, the positioning block 10, and the movable column 11, the four connecting components 3 can rotate and shift synchronously in the same direction. While the connecting components 3 are being adjusted, the upper plate 2 and the entire upper part of the upper plate 2 are smoothly tilted and moved. A linkage bevel gear 13 is fixedly connected to one side of the cross-shaped rotating component 12. A drive bevel gear 14 is movably connected to one side of the linkage bevel gear 13. A drive gear 15 is fixedly connected to the lower end of the drive bevel gear 14. A drive gear 15 is movably connected to one side of the drive gear 15. On one side surface of the lower plate 4, the meshing connection between the linkage bevel gear 13 and the drive bevel gear 14 is utilized, so that the drive bevel gear 14 rotates while driving the linkage bevel gear 13 rotates synchronously. At the same time, the rotation drives the cross rotating component 12 fixedly connected to it to offset and rotate synchronously in the same direction. The linkage bevel gear 13 and the drive bevel gear 14 are positioned on the same side, so that the two opposing linkage bevel gears 13 rotate in the same direction. The whole can drive the two opposing cross rotating components 12, the movable column 11 and the positioning block 10 to adjust synchronously, which facilitates the overall deflection and movement.

[0030] The linkage bevel gear 13 and the drive bevel gear 14 mesh with each other. The outer side of the drive gear 15 is movably connected to the linkage rack 16. There are two linkage racks 16, which are staggered and arranged in an upper and lower layer. By using the cooperation between the drive gear 15 and the linkage rack 16, the drive gear 15 rotates while the drive gear 15 rotates, thus realizing the synchronous rotation of the two drive bevel gears 14 and the linkage bevel gear 13.

[0031] A guide frame 17 is fixedly connected to one side surface of the lower plate 4. Two linkage racks 16 are movably disposed inside the guide frame 17. The outer side of the linkage rack 16 is in contact with the inner wall of the guide frame 17. A motor 18 is disposed at the lower end of the lower plate 4. The output end of the motor 18 is fixedly connected to one side of the drive gear 15. There are two motors 18, which are disposed at the lower ends of two adjacent drive gears 15. The motors 18 drive the drive gears 15 fixedly connected to their output ends and the opposite drive gears 15 synchronously. While the linkage rack 16 drives the drive gears 15, the guide frame 17 limits and protects them to prevent misalignment and external damage.

[0032] An adjustment groove 19 is provided on the inner side of the mounting bracket 1. An installation plate 20 is provided at the upper end of the adjustment groove 19. The upper end of the installation plate 20 is used to fix the polarization interference device. A hollow cylinder 21 is fixedly connected to the lower end of the installation plate 20. An adjustment spring 22 is fixedly connected to one side surface of the inner side of the hollow cylinder 21. A movable stake 23 is provided at the lower end of the hollow cylinder 21. The other end of the adjustment spring 22 is fixedly connected to one side surface of the movable stake 23. One end of the movable stake 23 is movably disposed inside one end of the hollow cylinder 21. The adjustment spring 22 is disposed between the hollow cylinder 21 and the movable stake 23. The elasticity of the adjustment spring 22 is used to facilitate the overall self-adaptive adjustment.

[0033] One end of the movable pile 23 is fixedly connected to an arc-shaped panel 24. An adjusting ball 26 is provided on one side of the arc-shaped panel 24. The side of the arc-shaped panel 24 is arc-shaped and is compatible with the adjusting ball 26. The adjusting ball 26 can be stably locked onto the lower side of the arc-shaped panel 24. The adjusting ball 26 is located inside the adjusting groove 19. An annular plate 25 is fixedly connected to the inner side of the adjusting groove 19. An adjusting frustum 27 is movably arranged in the middle of the annular plate 25. The outer side of the adjusting ball 26 is in contact with one side surface of the annular plate 25. The outer side of the adjusting ball 26 contacts one side surface of the adjusting frustum 27. After the polarization interference device is installed on the upper end of the mounting plate 20, during its movement, use, and stable placement, the three sets of hollow cylinders 21 and related components are used to achieve adaptive adjustment through the cooperation between the hollow cylinders 21, the adjusting springs 22, and the movable stakes 23. When the connecting plate 28 stabilizes the position of the three hollow cylinders 21, the position of the three adjusting balls 26 is simultaneously stabilized. The three adjusting balls 26 are evenly distributed in an equilateral triangular shape in the ring. Between plate 25 and adjusting frustum 27, when hollow cylinder 21 drives lower arc panel 24 to act on adjusting ball 26, the contact between adjusting ball 26 and annular plate 25 and adjusting frustum 27 adjusts the specific position of adjusting frustum 27 inside adjusting groove 19, and stabilizes the positional relationship of internal components. The whole device has extremely high stability during the movement, use and placement of polarization interference device. At the same time, when the motor 18 drives the drive gear 15 fixedly connected to its output end and the drive gear 15 set opposite to it synchronously, it can drive the upper plate 2 and the mounting bracket 1 connected to the upper end of the upper plate 2 to shift in a certain direction and angle, while ensuring that the mounting bracket 1 and the device at the upper end are always in a stable state. In addition, after the polarization interference device is installed on mounting plate 20, the cooperation between limiting post 8 and limiting cylinder 9 can be used to choose whether the mounting bracket 1 is installed on the upper end of upper plate 2, enhancing the controllability of the whole device and improving the selectivity of device use.

[0034] Three hollow cylinders 21 and three adjusting balls 26 are provided and evenly distributed in a circular array. A connecting plate 28 is fixedly connected between the three hollow cylinders 21. The connecting plate 28 is used to stabilize the positional relationship of the three hollow cylinders 21 and prevent them from being misaligned or deflected.

[0035] Before overall use, the polarization interference device is fixedly installed on the upper end of the mounting plate 20. The upper end of the mounting plate 20 is used to fix the polarization interference device, and the lower end is connected to three hollow cylinders 21 evenly distributed in a circular array. The hollow cylinders 21 are fixed in position by connecting plates 28. One end of the adjusting spring 22 inside the hollow cylinder 21 is connected to the inner wall of the hollow cylinder 21, and the other end is connected to the movable pile 23. One end of the movable pile 23 is movably set inside one end of the hollow cylinder 21, and the other end is connected to the arc panel 24, which is adapted to the adjusting ball 26. The adjusting ball 26 is set in the adjusting groove 19 and contacts the annular plate 25 and the adjusting frustum 27 in the adjusting groove 19. During the movement or placement of the equipment, the hollow cylinders 21, the adjusting springs 22 and the movable pile 23 are in contact. The system achieves adaptive adjustment. When the equipment is subjected to external forces or uneven ground, the elasticity of the adjusting spring 22 causes the movable stake 23 to drive the arc panel 24 to exert force on the adjusting ball 26. The adjusting ball 26 contacts the annular plate 25 and the adjusting frustum 27, adjusting the position of the adjusting frustum 27 within the adjusting groove 19, while simultaneously stabilizing the positional relationship of the internal components. The three adjusting balls 26 are evenly distributed in an equilateral triangle shape, which can better distribute the force and ensure the stability of the equipment. When the equipment moves, the three universal wheels 6 evenly distributed in a circular array at the lower end of the base plate 5 play a role, enabling the equipment to turn and move flexibly. When the equipment is moved to a designated position and needs to be placed stably, the four limiting posts 8 at the lower end of the mounting frame 1 can be inserted into the corresponding positions on the outer side of the upper plate 2. Within the four limiting cylinders 9, the mounting frame 1 and its upper part are stably placed on the upper plate 2 by the adaptive movable connection between the limiting posts 8 and the limiting cylinders 9, preventing the equipment from shaking. The connecting parts 3 are composed of positioning blocks 10 and movable posts 11. The four connecting parts 3 are arranged in a circumferential array. The two ends of the movable posts 11 are movably connected to the positioning blocks 10 through cross rotating parts 12. A linkage bevel gear 13 is fixed on one side of the cross rotating parts 12. The linkage bevel gear 13 meshes with the drive bevel gear 14. The lower end of the drive bevel gear 14 is connected to the drive gear 15. Two intersecting and layered linkage racks 16 are movably set inside the guide frame 17 and are movably connected to the drive gear 15. The two motors 18 at the lower end of the lower plate 4 are respectively The adjacent drive gear 15 is driven, and the drive gear 15 is driven to rotate synchronously through the linkage rack 16. This causes the linkage bevel gear 13 and the drive bevel gear 14 to rotate synchronously, which in turn drives the cross rotating component 12, the movable column 11 and the positioning block 10 to adjust synchronously, so as to achieve the smooth bias and movement of the upper plate 2 and the upper end as a whole. The guide frame 17 plays a limiting and protective role for the linkage rack 16 to prevent its misalignment and external damage. Through the coordinated work of the above components, the polarization interference device has extremely high stability during the movement, use and placement process. It can also flexibly adjust the direction and angle. In addition, the user can choose whether to install the mounting frame 1 on the upper plate 2 according to the needs, which enhances the controllability and selectivity of the device.
