Description

Technical Field

[0001] This utility model relates to the field of satellite communication maintenance technology, and in particular to a de-icing and snow removal mechanism for a flat panel antenna. Background Technology

[0002] In winter, low temperatures cause ice and snow accumulation on satellite communication antennas, significantly impacting their performance and leading to communication outages if not cleared promptly. Currently, manual snow removal and ice breaking for satellite communication antennas pose risks of poor working conditions, frostbite, and antenna damage. Even methods like heating or blowing snow removal suffer from system complexity, high energy consumption, and poor performance. Utility Model Content

[0003] This utility model provides a de-icing and snow removal mechanism for flat panel antennas, which overcomes the shortcomings of the prior art and solves the problem of inconvenience in de-icing and snow removal of antennas, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A de-icing and snow removal mechanism for a flat panel antenna includes a base, a vertical rod mounted on the base, and an antenna panel mounted on the upper end of the vertical rod. The antenna panel is inclined and mounted on the antenna panel. It includes a connecting mechanism disposed on the antenna panel, a shaking mechanism connected to the connecting mechanism, and a thin film disposed on the connecting mechanism, the thin film being located on the opening side of the antenna panel.

[0006] Furthermore, the connecting mechanism includes multiple L-shaped pieces mounted on two opposite sidewalls of the antenna panel. The upper inner side of the L-shaped pieces is provided with a spring, and the inner end of the spring is provided with a mounting plate. The mounting plate is mounted on the antenna panel by screws. The upper outer side of the L-shaped pieces on the same side is provided with a mounting strip. The film is mounted on the mounting strip by screws. The spring is designed to improve the shaking capability of the film, while the L-shaped pieces provide support for the mounting strip. Moreover, due to its L-shaped structure design, when the mounting strip shakes, it limits the movement of the mounting strip without affecting the shaking of the film.

[0007] Furthermore, the shaking mechanism includes a mounting base mounted on multiple L-shaped pieces, and a vibration motor is mounted on the mounting base. When the vibration motor is started, it drives the L-shaped pieces and the film to shake in a direction perpendicular to the length of the mounting strip.

[0008] Furthermore, the film is made of one of the following materials with low dielectric constant: polytetrafluoroethylene, polyimide, polycarbonate, etc. The selected material also needs to be highly weather-resistant and still flexible in low-temperature environments to avoid affecting vibration.

[0009] Furthermore, the jitter mechanism includes a pair of guide sleeves installed on the back side of the antenna panel, with a movable strip movably disposed inside the guide sleeves, and an end plate disposed at the outer end of the movable strip;

[0010] The guide sleeve has an oblong hole, through which a connecting screw is inserted. The inner end of the connecting screw is installed on the movable strip, and the outer end of the connecting screw is installed on the movable plate. The movable plate has an elongated hole, and the length direction of the elongated hole is parallel to the length direction of the movable plate.

[0011] A drive base is mounted on the back of the antenna panel, and a motor is mounted on the drive base. The output shaft of the motor rotates to form a turntable, on which a pair of swing rods are eccentrically mounted. The swing rods pass through elongated holes. When vibrating, the swing rods rotate under the drive of the motor, and in doing so, they act on the elongated holes, causing the movable plate to move back and forth. During this movement, the connecting parts and the thin film on them vibrate, and the vibration shakes off ice or snow from the thin film.

[0012] Furthermore, considering the short service life of the thin film material, and in order to ensure its shielding effect and facilitate replacement when damaged, the connection mechanism is specifically designed to include a pair of movable screws movably mounted on the end vertical plate. The end vertical plate has a pair of movable elongated holes, the length direction of which is parallel to the length direction of the end vertical plate. The movable screws pass through the movable elongated holes. A movable block is installed on the outer end of the movable screw. A V-shaped spring contact is located on the lower wall of the movable block. An installation plate is installed on the V-shaped spring. The installation plate is located on the end vertical plate. An upper clamping plate is installed on the upper end of the movable block. A lower clamping plate is located on the end vertical plate. The two ends of the thin film are clamped between the upper clamping plate and the lower clamping plate. A rotating outer plate is rotatably mounted on the end vertical plate. An actuating rod is located on the upper end of the rotating outer plate. A boss is located on the outer wall of the movable block. The outer periphery of the actuating rod acts on the upper end of the boss.

[0013] Furthermore, a lever is provided at the lower end of the rotating outer plate, which facilitates the rotation of the rotating outer plate.

[0014] Furthermore, the upper end of the boss is formed with an arc-shaped surface to enhance the clamping effect between the action rod and the boss.

[0015] Furthermore, to facilitate the shaking off of snow or ice, the inner end of the upper clamp is designed with a wedge shape.

[0016] The advantages of the above technical solution are:

[0017] This invention firstly prevents snow or ice from falling directly onto the antenna panel, and secondly makes it easy to remove snow or ice. Attached Figure Description

[0027] A de-icing and snow removal mechanism for a flat panel antenna includes a base, a vertical rod mounted on the base, and an antenna panel mounted on the upper end of the vertical rod. The antenna panel is angled and mounted on the antenna panel. It includes a connecting mechanism disposed on the antenna panel 12, a jitter mechanism connected to the connecting mechanism, and a thin film 41 disposed on the connecting mechanism, located on the open side of the antenna panel 12. The thin film 41 is made of one of the following materials: polytetrafluoroethylene, polyimide, and polycarbonate.

[0028] Example 1

[0029] like Figures 1-3As shown, specifically, the connecting mechanism includes multiple L-shaped pieces 9 mounted on two opposite sidewalls of the antenna panel 12. A spring 90 is provided on the inner side of the upper end of each L-shaped piece 9, and a mounting plate 91 is provided on the inner end of each spring 90. The mounting plate 91 is mounted on the antenna panel 12 by screws. A mounting strip 92 is provided on the outer side of the upper end of each L-shaped piece 9 on the same side. The diaphragm 41 is mounted on the mounting strip 92 by screws. The springs are designed to enhance the dithering capability of the diaphragm, while the L-shaped pieces support the mounting strip. Furthermore, their L-shaped design limits the movement of the mounting strip without affecting the dithering of the diaphragm. The dithering mechanism includes mounting seats 93 mounted on the multiple L-shaped pieces 9. A vibration motor 94 is mounted on the mounting seat 93. When the vibration motor 94 is activated, it drives the L-shaped pieces 9 and the diaphragm 41 to dither along a direction perpendicular to the length of the mounting strip 92.

[0030] When encountering snowfall, the vibration motor 94 is started, which drives a portion of the L-shaped sheet 9 to vibrate. While the L-shaped sheet 9 is vibrating, it will also drive the mounting strip 92 on it to vibrate. When the mounting strip 92 vibrates, it will cause the film 41 to reciprocate. As the film 41 vibrates, the snow on it will be shaken off, thereby achieving the purpose of snow removal and de-icing.

[0031] Example 2

[0032] like Figures 4-8 As shown, specifically, the jitter mechanism includes a pair of guide sleeves 2 installed on the back side of the antenna panel 12. A movable strip 20 is movably provided inside the guide sleeve 2. An end plate 29 is provided at the outer end of the movable strip 20. An oblong hole 21 is opened on the guide sleeve 2. A connecting screw 22 passes through the oblong hole 21. The inner end of the connecting screw 22 is installed on the movable strip 20. A movable plate 23 is installed at the outer end of the connecting screw 22. An elongated hole 24 is opened on the movable plate 23. The length direction of the elongated hole 24 is parallel to the length direction of the movable plate 23. A drive seat 26 is installed on the back side of the antenna panel 12. A motor 27 is installed on the drive seat 26. A turntable 28 is rotatably provided on the output shaft of the motor 27. A pair of swing rods 25 are eccentrically provided on the turntable 28. The swing rods 25 pass through the elongated hole 24.

[0033] The connecting mechanism includes a pair of movable screws 31 movably mounted on the end vertical plate 29. The end vertical plate 29 has a pair of elongated movable holes 30, the length of which is parallel to the length of the end vertical plate 29. The movable screws 31 pass through the elongated movable holes 30. A movable block 32 is mounted on the outer end of each movable screw 31. A V-shaped spring piece 33 contacts the lower wall of the movable block 32. A mounting plate 34 is mounted on the V-shaped spring piece 33. The mounting plate 34 is located on the end vertical plate 29. The movable block 32... An upper clamping plate 39 is installed at the upper end, and the inner end of the upper clamping plate 39 has a wedge-shaped structure. A lower clamping plate 40 is provided on the end vertical plate 29. The two ends of the film 41 are clamped between the upper clamping plate 39 and the lower clamping plate 40. A rotating outer plate 36 is rotatably provided on the end vertical plate 29. A toggle rod 38 is provided at the lower end of the rotating outer plate 36. An actuating rod 37 is provided at the upper end of the rotating outer plate 36. A boss is provided on the outer wall of the movable block 32. An arc-shaped surface is formed at the upper end of the boss. The outer periphery of the actuating rod 37 acts on the upper end of the boss.

[0034] In practical application of this embodiment, when snowfall occurs, snowflakes will fall onto the film 41. When it snows, the operator starts the motor 27, and the turntable 28 rotates under the drive of the motor 27. The rotation of the turntable 28 will drive the swing rod 25 to rotate. When the swing rod 25 rotates, it will act on the elongated hole 24, thereby causing the movable plate 23 to move back and forth. When the movable plate 23 moves, it will drive the movable strip 20 to move. As the movable strip 20 moves, it will drive the upper clamping plate 39, the lower clamping plate 40, and the film 41 between them to move back and forth, and shake off the snow on the film 41 through the back and forth movement of the film 41.

[0035] When replacing the film 41, the operator rotates the outer plate 36 outward to release the action of the lever 37 on the outer plate 36 on the boss. Then, the upper clamping plate 39 will move upward under the action of the V-shaped spring 33, at which point the clamping of the film 41 is released, and then the film 41 is replaced.

[0036] When fixing the film 41, the operator places both ends of the film 41 between the upper clamping plate 39 and the lower clamping plate 40, and then rotates the outer plate 36. The rotation of the outer plate 36 will cause the outer periphery of the action rod 37 to act on the upper end of the boss, thereby clamping the film 41 through the upper clamping plate 39 and the lower clamping plate 40.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
