Description

Technical Field

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

[0002] In meteorological monitoring, accurate wind direction measurement is crucial for weather forecasting and crop production management, which requires wind vanes to have the ability to operate stably over a long period of time to ensure the continuity and reliability of monitoring data.

[0003] However, existing wind direction indicators generally use bolts or welding to connect the indicator components to the main structure. When the indicator components are deformed or broken due to bird strikes or impacts from flying foreign objects under extreme weather conditions, maintenance personnel need to carry special tools to carry out tedious disassembly operations. In some cases, the entire device may need to be removed from its installation position before the damaged parts can be replaced. This not only consumes a lot of maintenance time, but may also cause interruption of meteorological data collection due to prolonged downtime, affecting the accuracy and timeliness of weather forecasts. The complex disassembly and assembly process not only increases labor costs, but also prolongs the downtime of the equipment. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a weather vane structure to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a weather vane structure, including a support rod, on which an installation mechanism is provided. The installation mechanism includes a rotating sleeve, a fixing rod, an indicator plate, a tail fin, and a quick-release mechanism. The rotating sleeve is provided with multiple sets rotating on the outer wall of the support rod, and the fixing rod is provided with multiple sets respectively fixed to the outer wall of the multiple sets of rotating sleeves. The indicator plate is provided inside the multiple sets of fixing rods, and the tail fin is provided inside the multiple sets of fixing rods. The quick-release mechanism is provided at the top of the multiple sets of fixing rods. The quick-release mechanism includes an insert rod, a fixing sleeve, a slider, a locking block, a locking groove, a push block, a limiting sleeve, and a limiting mechanism. The insert rod is inserted into the fixing rod, the fixing sleeve is inserted into the top of the insert rod, the slider is provided with multiple sets sliding on the outer wall of the fixing sleeve, the locking block is fixed to the bottom of the multiple sets of sliders, the locking groove is provided on the outer wall of the insert rod, the push block is fixed to the top of the multiple sets of sliders, and the limiting sleeve is provided on the outer wall of the fixing sleeve.

[0008] The present invention is further configured such that the limiting mechanism includes a sliding rod, a limiting block, a rotating sleeve, a limiting hole, and an unlocking hole. Multiple sets of sliding rods are distributed on the bottom surface of the limiting sleeve, the limiting block is fixed to the bottom end of the multiple sets of sliding rods, the rotating sleeve rotates on the outer wall of the fixed sleeve, multiple sets of limiting holes are distributed on the top surface of the rotating sleeve, and the unlocking hole is located at one end of the multiple sets of limiting holes. This design constructs a dual locking safety mechanism. The locking state is stably maintained through the cooperation of the limiting block and the limiting hole. Simultaneously, the unlocking hole ensures that the locking is released only when the rotating sleeve rotates to a specific position, preventing accidental loosening and accidental operation, and ensuring the structural stability of the weather vane under severe weather conditions.

[0009] The present invention is further configured such that each of the multiple sets of indicator plates and tail fins is provided with a reserved hole. This design allows the indicator plates and tail fins to be precisely connected to the plug rod through the reserved hole to form a standardized interface, realize modular installation and replacement, and complete the operation without special tools, which greatly improves the efficiency of on-site maintenance and is particularly suitable for emergency repairs at remote meteorological stations.

[0010] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a movable groove, and the movable groove is provided in multiple sets and is slidably connected to multiple sets of push blocks respectively. Push springs are connected between the inner walls of the multiple sets of push blocks and the movable grooves. This structure forms a reliable automatic reset mechanism. Under normal conditions, the push springs provide continuous elastic support to the push blocks, ensuring that the push blocks can quickly slide along the movable grooves and drive the locking blocks to disengage from the locking slots when unlocking. The separation of components can be completed without additional operations, simplifying the disassembly process.

[0011] The present invention is further configured such that each of the multiple sets of slide rods is provided with a return spring on its outer side, the top of each of the multiple sets of return springs is connected to the bottom surface of the limiting sleeve, and a connecting ring is connected to the bottom of each of the multiple sets of return springs. This elastic element design ensures that the limiting sleeve can automatically return to its original position in the unlocked state. The elastic force of the return spring restores the entire locking system to its initial state, preparing it for the next operation, thereby improving the reliability of continuous operation and the convenience of operation.

[0012] The present invention is further configured such that an arc-shaped block is fixedly provided on the bottom surface of each of the multiple sets of connecting rings, and an annular groove is provided on the top surface of the rotating sleeve. The multiple sets of arc-shaped blocks slide in the annular groove. This annular guide structure ensures that the rotating sleeve can accurately guide the arc-shaped blocks to move along a predetermined trajectory during rotation, preventing the system from jamming or deviating during operation. At the same time, it realizes the coordinated conversion between rotational motion and axial motion, making the entire operation process smoother and more stable.

[0013] The present invention is further configured such that a sliding hole is provided in the insertion rod, a top block is slidably provided in the sliding hole, and a compression spring is connected between the top block and the sliding hole. This elastic pop-out mechanism allows the insertion rod to automatically detach from the fixed sleeve by means of the restoring force of the compression spring in the unlocked state, so that the components can be separated without manual pulling out. It is particularly suitable for maintenance in high-altitude operations or in harsh weather conditions, reducing the operational burden and safety risks of the staff.

[0014] The present invention is further configured such that a positioning mechanism is provided on the bottom surface of the rotating sleeve. The positioning mechanism includes an installation ring, a positioning block, a fixing ring, a slide bar, a clamping block, a tension spring, and a positioning groove. The installation ring is fixed to the bottom surface of the rotating sleeve. Multiple sets of positioning blocks are distributed on the bottom surface of the installation ring. The fixing ring is fixed to the outer wall of the fixing sleeve. Multiple sets of slide bars are fixed to the top surface of the fixing ring. The clamping block slides on the outer wall of multiple sets of slide bars. Multiple sets of tension springs are respectively connected between multiple sets of clamping blocks. The positioning groove is provided on the top surface of multiple sets of clamping blocks. Each set of slide bars is fixed with a baffle. Multiple sets of baffles are provided and abut against the inner side of multiple sets of clamping blocks. This positioning system achieves precise positioning and locking of the rotating sleeve through the principle of elastic clamping. Multiple sets of tension springs provide appropriate preload to firmly position the clamping block. At the same time, the baffles prevent the clamping block from disengaging from the slide bar, ensuring that the system can maintain stable and reliable positioning performance after long-term use and multiple operations, and effectively preventing accidental loosening and position displacement caused by wind vibration.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a weather vane structure with the following advantages:

[0017] 1. The installation mechanism consists of a rotating sleeve, a fixing rod, an indicator plate, a tail fin, and a quick-release mechanism. It effectively solves the problem mentioned in the background technology of the difficulty in replacing the wind vane after it is damaged in harsh environments. The mechanism adopts a rotating connection design of multiple sets of rotating sleeves and support rods to ensure that the wind vane can rotate flexibly to accurately capture changes in wind direction. Multiple sets of fixing rods are fixed to the outer wall of the rotating sleeve as connecting structures to form a sturdy support frame. The indicator plate and tail fin are connected to the top of the fixing rod through reserved holes to achieve a modular design. This innovative structure allows meteorological monitoring station staff to quickly replace the indicator plate or tail fin without professional tools after the wind vane components are damaged in harsh weather conditions, greatly reducing maintenance time and downtime, and ensuring the continuity and reliability of meteorological data collection. It is particularly suitable for monitoring stations with difficult maintenance, such as those at high altitudes, islands, or remote mountainous areas.

[0018] 2. The quick-release mechanism includes a rod, a fixed sleeve, a slider, a locking block, a locking groove, a push block, a limiting sleeve, and a limiting mechanism. It cleverly solves the problems of cumbersome disassembly and assembly and difficult maintenance mentioned in the background technology. This mechanism utilizes the locking principle of the locking block and the locking groove, combined with the push block design guided by the movable groove, to achieve rapid locking and release of the indicator plate or tail fin. The limiting mechanism, through the cooperation of the sliding rod, the limiting block, and the limiting hole and unlocking hole on the rotating sleeve, constructs a double-safety locking system. The push spring provides the reset power for the push block, ensuring that the locking block can quickly disengage during unlocking. The combination of the reset spring and the connecting ring ensures the reliable return of the limiting sleeve. These designs significantly simplify the maintenance operation process, enabling non-professionals to complete component replacement without adjusting the balance or calibrating the wind direction. This effectively solves the maintenance problems in remote areas and improves the service life and data reliability of the wind vane.

[0019] 3. The positioning mechanism consists of an installation ring, positioning block, fixing ring, slide bar, clamping block, tension spring, and positioning groove. It innovatively solves the problems of loose fixing structure and calibration difficulties mentioned in the background technology. This mechanism uses multiple sets of positioning blocks and positioning grooves for precise engagement, combined with a tension spring-driven clamping block holding system, to achieve accurate locking of the rotating sleeve position. The limiting design of the slide bar and baffle prevents the clamping block from disengaging from the slide rail. This positioning mechanism ensures precise switching between the locked and unlocked states of the quick-lock mechanism, avoiding accidental state transitions. Simultaneously, this structure has self-adjusting capabilities, adapting to wear changes during long-term use and maintaining a stable locking force. The design of the positioning mechanism greatly improves the reliability of the wind vane under extreme weather conditions, reduces data errors caused by loose connections, lowers maintenance frequency and costs, and provides more stable and accurate wind direction data support for meteorological monitoring.

The rotating sleeve 15 rotates on the outer wall of the fixed sleeve 7. Multiple sets of limiting holes 16 are distributed on the top surface of the rotating sleeve 15. The unlocking hole 17 is located at one end of the multiple sets of limiting holes 16. By rotating the rotating sleeve 15, the limiting block 14 switches between the limiting hole 16 and the unlocking hole 17, realizing dual-state control of locking and unlocking.

[0031] Multiple indicator plates 4 and tail fin 5 are equipped with pre-drilled holes, which serve as connection points to enable modular installation and quick replacement, improving component interchangeability and maintenance efficiency.

[0032] The outer wall of the fixed sleeve 7 is provided with a movable groove 18. Multiple movable grooves 18 are provided and are slidably connected to multiple sets of push blocks 11 respectively. Push springs 19 are connected between the inner wall of the multiple sets of push blocks 11 and the movable groove 18. The push springs 19 keep the push blocks 11 in an outward trend. After the limiting sleeve 12 is removed, it can automatically slide along the movable groove 18 to return to the initial position, thereby realizing automatic unlocking.

[0033] Each set of slide rods 13 is equipped with a return spring 20 on its outer side. The top of each set of return springs 20 is connected to the bottom surface of the limit sleeve 12. Each set of return springs 20 is connected to a connecting ring 21 at its bottom. When locked, the return spring 20 is compressed and stores energy. When unlocked, it releases energy to push the limit sleeve 12 to reset, ensuring that the system can automatically return to its initial state.

[0034] Multiple sets of connecting rings 21 are fixed with arc-shaped blocks 22 on their bottom surfaces, and the rotating sleeve 15 is provided with an annular groove 23 on its top surface. Multiple sets of arc-shaped blocks 22 slide in the annular groove 23. The combined transmission of rotational motion and axial motion is achieved through the sliding of the arc-shaped blocks 22 in the annular groove 23, ensuring precise control of the motion trajectory.

[0035] The insertion rod 6 has a sliding hole 24, and a top block 25 is slidably disposed in the sliding hole 24. A compression spring 26 is connected between the top block 25 and the sliding hole 24. The top block 25 is pushed out by the elastic force of the compression spring 26. In the unlocked state, the insertion rod 6 is automatically ejected from the fixing sleeve 7, realizing the separation of the parts without external force.

[0036] A positioning mechanism is provided on the bottom surface of the rotating sleeve 15. The positioning mechanism includes a mounting ring 27, a positioning block 28, a fixing ring 29, a slide bar 30, a clamping block 31, a tension spring 32, and a positioning groove 33. The mounting ring 27 is fixed to the bottom surface of the rotating sleeve 15. Multiple sets of positioning blocks 28 are distributed on the bottom surface of the mounting ring 27. The fixing ring 29 is fixed to the outer wall of the fixing sleeve 7. Multiple sets of slide bars 30 are fixed to the top surface of the fixing ring 29. The clamping block 31 slides on the outer wall of multiple sets of slide bars 30. Multiple sets of tension springs 32 are respectively connected between multiple sets of clamping blocks 31. The positioning groove 33 is provided on the top surface of multiple sets of clamping blocks 31. Baffles 34 are fixed on each of the multiple sets of slide bars 30. Multiple sets of baffles 34 are provided and abut against the inner side of multiple sets of clamping blocks 31. The tension springs 32 pull the clamping blocks 31 to engage with the positioning blocks 28, forming a mechanical lock at a preset position. At the same time, the baffles 34 restrict the excessive movement of the clamping blocks 31, ensuring reliable positioning and accurate operation.

[0037] In this embodiment, when it is necessary to install the indicator plate 4 or the tail fin 5, the reserved hole on the indicator plate 4 or the tail fin 5 is aligned with the fixing sleeve 7 at the top of the fixing rod 3. Then, the insertion rod 6 is inserted into the reserved hole and the fixing sleeve 7. The top block 25 abuts against the inner wall of the fixing sleeve 7 and squeezes the compression spring 26. The limiting sleeve 12 is pulled to abut against the outer wall of the multiple sets of push blocks 11 and stretches the multiple sets of return springs 20. This causes the multiple sets of push blocks 11 to push the locking block 9 to abut against the slot 10 through the slider 8, thus locking the insertion rod 6. Then, the limiting sleeve 12 pulls multiple sets of sliding rods 13 to move the limiting block 14 into the unlocking hole 17. Then, the rotating sleeve 15 is rotated to move multiple sets of limiting blocks 14 into the limiting hole 16. The limiting sleeve 12 is fixed by the multiple sets of limiting blocks 14 abutting against the outer wall of the rotating sleeve 15. The clamping block 31 is clamped against the outer wall of the multiple sets of positioning blocks 28 by multiple sets of tension springs 32, so that the multiple sets of positioning blocks 28 abut against the positioning groove 33 to position the rotating sleeve 15. Thus, the quick installation of the indicator plate 4 or the tail wing 5 can be completed.

[0038] More specifically, when it is necessary to disassemble the indicator plate 4 or the tail fin 5, rotating the rotating sleeve 15 drives multiple sets of positioning blocks 28 to push multiple sets of clamping blocks 31 respectively, causing the multiple sets of clamping blocks 31 to slide along multiple sets of slide bars 30, so that the multiple sets of clamping blocks 31 stretch the tension springs 32. When the multiple sets of positioning blocks 28 move into the next set of positioning grooves 33, the multiple sets of tension springs 32 reset and pull the clamping blocks 31 to clamp them on the outer wall of the positioning blocks 28. Continuously rotating the rotating sleeve 15 causes the multiple sets of positioning blocks 28 to move within the multiple sets of positioning grooves 33. The rotation of the rotating sleeve 15 causes the multiple sets of positioning blocks 28 to move within the multiple sets of positioning grooves 33. The group of limiting blocks 14 moves into the unlocking hole 17 to release the contact between the group of limiting blocks 14 and the outer wall of the rotating sleeve 15, and release the fixation of the limiting sleeve 12. The limiting sleeve 12 is pulled by the group of reset springs 20 to release the contact between the group of push blocks 11 and the group of push springs 19 to push the push block 11 to slide along the movable groove 18 and pull the group of locking blocks 9 to disengage from the locking groove 10 to release the locking of the insertion rod 6. The top block 25 is reset by the compression spring 26 and the insertion rod 6 is disengaged from the fixing sleeve 7 to release the insertion of the indicator plate 4 or the tail wing 5, thus completing the disassembly of the indicator plate 4 or the tail wing 5.

[0039] In summary, during the use or operation of the overall equipment: when it is necessary to install the indicator plate 4 or tail fin 5, align the reserved hole on the indicator plate 4 or tail fin 5 with the fixing sleeve 7 at the top of the fixing rod 3, then insert the insertion rod 6 into the reserved hole and the fixing sleeve 7. The top block 25 abuts against the inner wall of the fixing sleeve 7 and compresses the compression spring 26, pulling the limiting sleeve 12 against the outer wall of the multiple sets of push blocks 11 and stretching the multiple sets of return springs 20, so that the multiple sets of push blocks 11 push the locking block 9 against the slot 10 through the slider 8, thus fixing the insertion rod. 6. The locking sleeve 12 pulls multiple sets of sliding rods 13 to move the limiting block 14 into the unlocking hole 17. Then, the rotating sleeve 15 is rotated to move multiple sets of limiting blocks 14 into the limiting hole 16. The limiting sleeve 12 is fixed by the multiple sets of limiting blocks 14 abutting against the outer wall of the rotating sleeve 15. The clamping block 31 is clamped against the outer wall of multiple sets of positioning blocks 28 by multiple sets of tension springs 32, so that the multiple sets of positioning blocks 28 abut against the positioning groove 33 to position the rotating sleeve 15. Thus, the quick installation of the indicator plate 4 or the tail wing 5 can be completed.

[0040] When it is necessary to disassemble the indicator plate 4 or the tail fin 5, rotating the rotating sleeve 15 drives multiple sets of positioning blocks 28 to push multiple sets of clamping blocks 31 respectively, causing the multiple sets of clamping blocks 31 to slide along multiple sets of slide bars 30, so that the multiple sets of clamping blocks 31 stretch the tension springs 32. When the multiple sets of positioning blocks 28 move into the next set of positioning grooves 33, the multiple sets of tension springs 32 reset and pull the clamping blocks 31 to clamp them on the outer wall of the positioning blocks 28. Continuously rotating the rotating sleeve 15 causes the multiple sets of positioning blocks 28 to move within the multiple sets of positioning grooves 33. The rotation of the rotating sleeve 15 causes the multiple sets of limiting Block 14 moves into the unlocking hole 17 to release the contact between multiple sets of limiting blocks 14 and the outer wall of the rotating sleeve 15, and release the fixation of the limiting sleeve 12. Multiple sets of reset springs 20 pull the limiting sleeve 12 to release the contact between multiple sets of push blocks 11. Multiple sets of push springs 19 push the push block 11 to slide along the movable groove 18 and pull multiple sets of locking blocks 9 out of the locking groove 10 to release the locking of the insertion rod 6. The compression spring 26 resets and pushes the top block 25, and pushes the insertion rod 6 out of the fixing sleeve 7 to release the insertion of the indicator plate 4 or tail wing 5, thus completing the disassembly of the indicator plate 4 or tail wing 5.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
