Description

Technical Field

[0001] This utility model relates to the field of meteorological weather vane technology, and more specifically, to a weather vane structure. Background Technology

[0002] In existing technologies, the height of meteorological wind vanes is fixed, making stepless adjustment impossible. Specifically, during meteorological monitoring, the requirements for wind vane height vary depending on the geographical location, season, and monitoring objective. Some scenarios require higher wind vanes to avoid interference from surrounding terrain, vegetation, or buildings, thus obtaining more accurate wind direction data. Other scenarios require lower wind vanes for easier installation and maintenance. Especially in meteorological monitoring in complex terrain areas, wind vane height directly affects the accuracy and representativeness of measurement data. However, existing wind vane structures often employ a fixed design, and once the height is determined, it cannot be adjusted, lacking flexibility and adaptability. This rigid wind vane design prevents meteorological staff from making targeted adjustments for different environmental conditions and monitoring needs. This often results in increased data errors due to unsuitable wind vane heights, or the need to equip multiple specifications of wind vanes due to the inability to adjust the height, increasing equipment costs. For meteorological stations that need to conduct accurate wind direction monitoring in variable environments, flexible adjustment of wind vane height is particularly crucial, and the limitations of existing equipment severely restrict the improvement of meteorological monitoring data quality and monitoring efficiency.

[0003] Secondly, while some devices achieve flexible adjustment of the wind vane height through the cooperation of certain components, their simple structure and low stability make them prone to displacement and loosening due to external forces, resulting in changes in the adjusted wind vane height. The fixing and locking devices of these improved devices are not well-designed. Existing adjustable wind vanes generally suffer from the problem of "unreliable fixation after adjustment, leading to unstable measurement data." When wind vanes are used in the field, they are often affected by natural factors such as strong winds and changes in rainfall over a long period of time. These factors will continuously impact and vibrate the fixed structure of the wind vane. These external forces will continuously act on the adjustment mechanism, gradually causing the fixed components to loosen or shift. In addition, the equipment is also subject to interference from external factors such as frequent touching by operators during installation and maintenance. These factors will also cause slight changes in the position of the adjustment mechanism. Over time, these slight changes will accumulate into significant deviations, resulting in a significant difference between the actual wind vane height and the set value. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a meteorological weather vane structure, which has the following beneficial effects:

[0017] 1. By coordinating components such as the wind vane, lifting rod, shifting sleeve, correction sleeve, actuating block, actuating plate, and moving sleeve, this device effectively solves the technical problem of fixed wind vane height in existing technologies, which prevents stepless adjustment of the wind vane height. This device innovatively adopts a structural design where the moving sleeve and correction sleeve work together, combined with the linkage structure of other components. This allows meteorological staff to flexibly adjust the wind vane height through simple rotation operations. In particular, the design of the conversion hole on the conversion plate, and the inclined sliding mechanism of the slope plate and slope groove, greatly improve the flexibility and ease of operation of height adjustment. This significantly enhances the adaptability of the wind vane to different geographical locations, seasons, and monitoring purposes. This stepless adjustment design is especially important in meteorological monitoring in complex terrain areas, completely solving the problem of increased data errors caused by fixed wind vane height and avoiding the drawback of needing to equip multiple specifications of wind vanes, which increases equipment costs.

[0018] 2. By employing a multi-locking and positioning mechanism design comprised of components such as a transformation plate, limiting sleeve, linkage block, pressure rod, and mating block, this design solves the technical problem in existing adjustable wind vanes where the structure is simple, instable, and prone to displacement and loosening due to external forces, leading to variations in the adjusted wind vane height. The sliding limit design of the moving block and moving groove, the elastic support structure of the linkage spring and linkage rod, and the mating of the pressure rod and transformation hole, among other multiple positioning structures, interact to form a complete and stable locking system. In particular, the insertion locking design of the progressive rod and progressive groove, and the tension reset mechanism of the motion spring and progressive plate, not only ensure smooth adjustment but also significantly enhance the stability of the adjusted structure. This effectively resists the long-term effects of natural factors such as strong winds and rainfall, greatly reduces interference from external forces such as frequent touches by operators during installation and maintenance, and effectively avoids the accumulation of significant deviations due to minor changes in the position of the adjustment mechanism over time. This ensures the consistency between the actual wind vane height and the set value, improving the accuracy and reliability of meteorological data monitoring. Attached Figure Description

[0028] Please see Figures 1-5 A meteorological weather vane structure includes a weather vane 1, a lifting rod 2 below the weather vane 1, the weather vane 1 being rotatably mounted above the lifting rod 2, a movable sliding sleeve 3 on the outer side of the lifting rod 2, a limiting sleeve 4 on the outer side of the sliding sleeve 3, a pressure rod 5 fixedly connected to one side of the limiting sleeve 4, a pressure spring 6 movably sleeved on the outer side of the pressure rod 5, a rotatable correction sleeve 7 on the outer side of the sliding sleeve 3, a moving frame 8 connected to one side of the correction sleeve 7, a moving sleeve 9 on the outer side of the sliding sleeve 3, a changing plate 10 rotatably mounted on the outer side of the sliding sleeve 3, a changing hole 11 on the changing plate 10, the outer wall of the moving sleeve 9 being movably connected to the inner wall of the correction sleeve 7 via threads, multiple progressive grooves 12 on the outer side of the sliding sleeve 3, a connecting block 13 fixedly connected to one side of the changing plate 10, and a mating block 1 fixedly mounted on the outer side of the lifting rod 2. 4. A connecting spring 15 is movably connected between the connecting block 13 and the mating block 14. A progressive rod 16 is slidably provided in the motion frame 8. One end of the progressive rod 16 is connected to a progressive plate 17. A motion spring 18 is movably sleeved on the outside of the progressive rod 16. The two ends of the motion spring 18 are respectively connected to the progressive plate 17 and the motion frame 8. An inclined groove 19 is opened on the inner side of the moving sleeve 3. An inclined plate 20 is slidably provided in the inclined groove 19. An action block 21 is fixedly connected to one side of the inclined plate 20. An action spring 22 is connected to one side of the action block 21. An action plate 23 is connected to the other end of the action spring 22. An action sleeve 24 is movably provided in the moving sleeve 3. A matching groove 25 is opened on one side of the action sleeve 24. A matching block 26 is connected to one side of the action block 21. The matching block 26 is slidably located in the matching groove 25.

[0029] The lower side of the transfer sleeve 3 is fixedly connected to a fixed sleeve 27, the bottom end of the fixed sleeve 27 is fixedly connected to a main insertion rod 28, and one side of the fixed sleeve 27 is fixedly connected to a secondary insertion rod 29.

[0030] A direction sign 30 is fixedly installed on the outside of the lifting pole 2.

[0031] In this embodiment, when the height of the wind vane 1 needs to be adjusted, the transformation plate 10 is first rotated forward, causing the transformation plate 10 to drive the connecting block 13 on one side to rotate forward. The connecting block 13 will also drive the connecting rod 37 on one side to rotate forward along the connecting hole 38. At the same time, the connecting block 13 will cooperate with the mating block 14 to compress the connecting spring 15, causing the transformation plate 10 to drive the transformation hole 11 to rotate forward. When the connecting spring 15 is compressed to its limit, the transformation hole 11 will rotate to a position concentric with the pressing rod 5. Then, the limiting sleeve 4 is pushed, causing the limiting sleeve 4 to drive the inner floating block 33 to slide along the floating groove 34. The limiting sleeve 4 will also drive the connecting rod 37 on one side to rotate forward. The pressure rod 5 gradually slides into the conversion hole 11. Simultaneously, the limiting sleeve 4, in conjunction with the conversion plate 10, compresses the pressure spring 6, causing the limiting sleeve 4 to gradually cease limiting the outer wall of the progressive plate 17. Then, the correction sleeve 7 rotates forward, causing one side of the motion frame 8 to rotate forward. The motion frame 8 then causes the progressive rod 16 and the progressive plate 17 to rotate forward. At this time, the inner wall of the progressive groove 12 compresses one end of the progressive rod 16. Due to the rounded corner design at the edge of the inner wall of the progressive groove 12 and one end of the progressive rod 16, one end of the progressive rod 16 slides out of the progressive groove 12, and the other end of the progressive rod 16 causes the progressive plate 17 to slide outward. The progressive plate 17 will cause the motion spring 18 to stretch outward. At the same time, due to the movable connection between the inner wall of the correction sleeve 7 and the outer wall of the motion sleeve 9 through threads, and the rotation limit of the motion sleeve 9 by the engaging block 40 and the engaging groove 39, the motion sleeve 9 will then cause the inner engaging block 40 to slide along the engaging groove 39, and the engaging block 40 will cause the inner moving sleeve 24 to slide. Then the moving sleeve 24 will cause the engaging block 26 to move through the matching groove 25. Then the matching block 26 will cause the moving block 21 on one side to move. Then the moving block 21 will cause the guide rod 31, the guide groove 32, the motion spring 22 and the motion plate 23 to move, and the moving block... 21 will cause the other side inclined plate 20 to slide along the inclined groove 19. At the same time, the inclined plate 20 will cause the action block 21 to spread outward, so that the action block 21 will cause the matching block 26 on one side to slide outward along the matching groove 25, so that the distance between the action block 21 and the action plate 23 will be lengthened, and then the action spring 22 will gradually return to its original position. When the action spring 22 is fully returned to its original position, the action block 21 will cause the guide groove 32, guide rod 31, action spring 22 and action plate 23 to slide outward, so that the action plate 23 will no longer clamp the outer wall of the lifting rod 2, and then the lifting rod 2 will slide, so that the lifting rod 2 will drive the wind vane 1 to slide up and down.

[0032] Please see Figures 3-5 As a further implementation of the overall equipment: a guide rod 31 is fixedly connected to one side of the action plate 23, and a guide groove 32 is opened in the action block 21. One end of the guide rod 31 is slidably inserted into the guide groove 32.

[0033] A movable block 33 is fixedly provided on the inner side of the limiting sleeve 4, and a movable groove 34 is provided on the outer side of the lifting rod 2, and the movable block 33 slides in the movable groove 34.

[0034] Multiple anti-slip strips 35 are provided on the outer side of the transformation plate 10, the correction sleeve 7 and the limiting sleeve 4, and multiple rubber strips 36 are fixedly connected to the inner side of the action plate 23.

[0035] A linkage rod 37 is connected to one side of the linkage block 13, and a linkage hole 38 is opened in the mating block 14. The linkage spring 15 is movably sleeved on the outside of the linkage rod 37, and one end of the linkage rod 37 slides into the linkage hole 38.

[0036] The side wall of the moving sleeve 3 is provided with a fitting groove 39, and a fitting block 40 is slidably provided in the fitting groove 39. The inner wall of the moving sleeve 9 is fixedly connected to the outer wall of the action sleeve 24 through the fitting block 40.

[0037] More specifically, after the height of the weather vane 1 is adjusted appropriately, the correction sleeve 7 is rotated in the reverse direction. The correction sleeve 7 will drive the movement frame 8 on one side to rotate in the reverse direction, and the movement frame 8 will drive the progressive rod 16, the progressive plate 17, and the movement spring 18 to rotate in the reverse direction. At the same time, due to the threaded fit between the inner wall of the correction sleeve 7 and the outer wall of the movement sleeve 9, the movement sleeve 9 will drive the engaging block 40 to slide in the reverse direction along the engaging groove 39. Simultaneously, the engaging block 40 will drive the inner moving sleeve 24 to slide in the reverse direction. The moving sleeve 24 will push the moving block 21 on one side to slide in the reverse direction, and the moving block 21 will drive the guide rod 31, the guide groove 32, the moving spring 22, and the moving plate 23 on one side to slide in the reverse direction. At the same time, the moving block 21 will drive the inclined plate 20 on the other side to slide in the reverse direction along the inclined groove 19. The inclined plate 20 slides, and the inclined plate 20 will drive the one-side action block 21 to converge inward. Then, the action block 21 will drive the one-side matching block 26 to slide inward along the matching groove 25. The action block 21 will also drive the guide groove 32, guide rod 31, action spring 22 and action plate 23 to converge inward. Then, the inner wall of the action plate 23 will gradually come into contact with the outer wall of the lifting rod 2. Then, the distance between the action block 21 and the action plate 23 will shorten, so that the guide rod 31 connected to one side of the action plate 23 will slide into the inner side of the guide groove 32. The action plate 23 and the action block 21 will cooperate to gradually press the action spring 22. Then, the inner wall of the action plate 23 will clamp the outer wall of the lifting rod 2 through multiple rubber strips 36 to fix the position of the moving sleeve 3. At the same time, the moving frame 8 drives the progressive rod 16 and other components to rotate and reset to the position corresponding to the original progressive slot 12. Then, the motion spring 18 resets and pulls the progressive plate 17, causing the progressive plate 17 to drive the progressive rod 16 to slide inward. Then, one end of the progressive rod 16 will be reinserted into the original progressive slot 12. Then, the limiting sleeve 4 is released, and the pressure spring 6 pushes the limiting sleeve 4 to slide and reset, causing the limiting sleeve 4 to drive the inner moving block 33 to slide and reset along the moving slot 34. The limiting sleeve 4 will also drive the pressure rod 5 on one side to slide and reset, so that the pressure rod 5 no longer passes through the conversion hole 11. At this time, the pressure rod 5 no longer limits the conversion plate 10 through the conversion hole 11. Then, the linkage spring 15 resets and pushes the linkage block 13, causing the linkage block to... 13 drives the connecting rod 37 on one side to rotate in the opposite direction and reset along the connecting hole 38. The connecting block 13 will drive the changing hole 11 to rotate in the opposite direction and reset to a position that does not correspond to the pressure rod 5 through the changing plate 10. Then the pressure rod 5 limits and supports the limiting sleeve 4 to one side of the changing plate 10. With the help of the moving block 33 and the moving groove 34, the limiting sleeve 4 is limited and cannot move. Then the inner wall of the limiting sleeve 4 limits the outer wall of the progressive plate 17 again, so that the progressive plate 17 and the progressive rod 16 cannot slide outward. Then the progressive rod 16 and the progressive groove 12 cooperate to limit and lock the moving frame 8, so that the moving frame 8 and the correction sleeve 7 cannot rotate accidentally, thereby ensuring the structural stability of the wind vane 1 after height adjustment and ensuring stable use.

[0038] In summary, during the use or operation of the overall equipment: when it is necessary to adjust the height of the wind vane 1, firstly, rotate the transformation plate 10 in the forward direction, causing the transformation plate 10 to drive the connecting block 13 on one side to rotate in the forward direction. The connecting block 13 will also drive the connecting rod 37 on one side to rotate in the forward direction along the connecting hole 38. Simultaneously, the connecting block 13 will cooperate with the mating block 14 to compress the connecting spring 15, causing the transformation plate 10 to drive the transformation hole 11 to rotate in the forward direction. When the connecting spring 15 is compressed to its limit, the transformation hole 11 will rotate to a position concentric with the pressure rod 5. Then, push the limiting sleeve 4, causing the limiting sleeve 4 to drive the inner moving block 33 to slide along the moving groove 34. 4 will cause the pressure rod 5 on one side to gradually slide into the conversion hole 11. At the same time, the limiting sleeve 4 will cooperate with the conversion plate 10 to squeeze the pressure spring 6, so that the limiting sleeve 4 will gradually stop limiting the outer wall of the progressive plate 17. Then, the correction sleeve 7 will rotate forward, and the correction sleeve 7 will drive the moving frame 8 on one side to rotate forward. Then the moving frame 8 will drive the progressive rod 16 and the progressive plate 17 to rotate forward. At this time, the inner wall of the progressive groove 12 will squeeze one end of the progressive rod 16. Due to the rounded corner structure design of the inner wall edge of the progressive groove 12 and one end of the progressive rod 16, one end of the progressive rod 16 will slide out of the progressive groove 12, and the other end of the progressive rod 16 will drive the progressive plate 17 to the outside. The sliding motion causes the progressive plate 17 to pull the motion spring 18 outward. Simultaneously, due to the movable connection between the inner wall of the correction sleeve 7 and the outer wall of the motion sleeve 9 via threads, and the limiting rotation of the motion sleeve 9 by the engaging block 40 and engaging groove 39, the motion sleeve 9 drives the inner engaging block 40 to slide along the engaging groove 39. The engaging block 40 then drives the inner actuating sleeve 24 to slide. The actuating sleeve 24 then drives the engaging block 26 to move via the engaging groove 25. The engaging block 26 then drives one actuating block 21 to move. The actuating block 21 then drives the guide rod 31, guide groove 32, actuating spring 22, and actuating plate 23 to move. The action block 21 will drive the other side inclined plate 20 to slide along the inclined groove 19. At the same time, the inclined plate 20 will drive the action block 21 to spread outward, so that the action block 21 will drive the matching block 26 on one side to slide outward along the matching groove 25, so that the distance between the action block 21 and the action plate 23 will be lengthened, and then the action spring 22 will gradually return to its original position. When the action spring 22 is fully returned to its original position, the action block 21 will drive the guide groove 32, guide rod 31, action spring 22 and action plate 23 to slide outward, so that the action plate 23 will no longer clamp the outer wall of the lifting rod 2, and then the lifting rod 2 will slide, so that the lifting rod 2 will drive the wind vane 1 to slide up and down.

[0039] Once the height of the weather vane 1 is properly adjusted, the correction sleeve 7 is rotated in the reverse direction. The correction sleeve 7 will cause one side of the moving frame 8 to rotate in the reverse direction, and the moving frame 8 will cause the progressive rod 16, progressive plate 17, and moving spring 18 to rotate in the reverse direction. Simultaneously, due to the threaded fit between the inner wall of the correction sleeve 7 and the outer wall of the moving sleeve 9, the moving sleeve 9 will cause the engaging block 40 to slide in the reverse direction along the engaging groove 39. At the same time, the engaging block 40 will cause the inner moving sleeve 24 to slide in the reverse direction. The moving sleeve 24 will push one side of the moving block 21 to slide in the reverse direction, and the moving block 21 will cause one side of the guide rod 31, guide groove 32, moving spring 22, and moving plate 23 to slide in the reverse direction. Simultaneously, the moving block 21 will cause the other side of the inclined plate 20 to slide in the reverse direction along the inclined groove 19. The inclined plate 20 will cause one side of the action block 21 to converge inward. Then, the action block 21 will cause one side of the matching block 26 to slide inward along the matching groove 25. The action block 21 will also cause the guide groove 32, guide rod 31, action spring 22 and action plate 23 to converge inward. Then, the inner wall of the action plate 23 will gradually come into contact with the outer wall of the lifting rod 2. Then, the distance between the action block 21 and the action plate 23 will shorten, so that the guide rod 31 connected to one side of the action plate 23 will slide into the inner side of the guide groove 32. The action plate 23 and the action block 21 will cooperate to gradually press the action spring 22. Then, the inner wall of the action plate 23 will clamp the outer wall of the lifting rod 2 through multiple rubber strips 36 to fix the position of the transfer sleeve 3. At the same time, the motion frame 8 rigidly The progressive rod 16 and other components rotate and reset to the position corresponding to the original progressive slot 12. Then, the motion spring 18 resets and pulls the progressive plate 17, causing the progressive plate 17 to slide the progressive rod 16 inward. One end of the progressive rod 16 will then re-insert into the original progressive slot 12. Then, the limiting sleeve 4 is released, and the pressure spring 6 pushes the limiting sleeve 4 to slide and reset, causing the limiting sleeve 4 to slide and reset the inner moving block 33 along the moving slot 34. The limiting sleeve 4 will also drive the pressure rod 5 on one side to slide and reset, so that the pressure rod 5 no longer passes through the conversion hole 11. At this time, the pressure rod 5 no longer limits the conversion plate 10 through the conversion hole 11. Then, the linkage spring 15 resets and pushes the linkage block 13, causing the linkage block 1... 3. The connecting rod 37 on one side rotates in the opposite direction along the connecting hole 38 to reset, and the connecting block 13 will drive the changing hole 11 to rotate in the opposite direction to reset to a position that does not correspond to the pressing rod 5 through the changing plate 10. Then the pressing rod 5 limits and supports the limiting sleeve 4 to one side of the changing plate 10. With the help of the moving block 33 and the moving groove 34, the limiting sleeve 4 is limited, so that the limiting sleeve 4 cannot move. Then the inner wall of the limiting sleeve 4 limits the outer wall of the progressive plate 17 again, so that the progressive plate 17 and the progressive rod 16 cannot slide outward. Then the progressive rod 16 and the progressive groove 12 cooperate to realize the limiting and locking of the moving frame 8, so that the moving frame 8 and the correction sleeve 7 cannot rotate accidentally, thereby ensuring the structural stability of the wind vane 1 after height adjustment and ensuring stable use.

For all the fixed connections mentioned above, welding is preferred.
