Description

Technical Field

[0001] This utility model relates to the field of meteorological and environmental monitoring technology, specifically to a wind calibration mechanism for a wind data acquisition device. Background Technology

[0002] In wind power generation scenarios, wind turbines need to rely on the precise guidance of wind calibration mechanisms to achieve real-time yaw of the turbine nacelle in order to maximize wind energy capture; in meteorological monitoring scenarios, wind calibration mechanisms need to ensure that the data acquisition equipment is always facing the wind direction to ensure the continuity and accuracy of wind speed and direction data.

[0003] For example, Chinese patent CN222232931U discloses a data acquisition device, including a data acquisition unit, a base, a battery, and a wind power generation device. The data acquisition unit is used to collect data. The base is connected to the data acquisition unit and provides support. The battery is electrically connected to the data acquisition unit and provides power. The wind power generation device is electrically connected to the battery and converts wind energy into electrical energy, thereby charging the battery and assisting in battery storage. The data acquisition device provided in this application is used for data acquisition.

[0004] While the above solutions have the advantages mentioned above, they also have disadvantages: because the mating parts of the shaft assembly and guide assembly of the wind calibration mechanism are mostly connected by a single bushing, the long-term relative rotation between the bushing and the support rod of the shaft assembly is prone to wear gaps. These gaps not only cause coaxiality deviations between the components, leading to jamming and offset of the wind guide and resulting in a decrease in calibration, but also provide a channel for the intrusion of impurities such as sand and rainwater, aggravating the wear of internal components and shortening the overall service life of the mechanism. Furthermore, the existing mechanisms lack a structure that can automatically compensate for wear gaps, requiring frequent shutdowns for maintenance. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a wind calibration mechanism for a wind power data acquisition device, solving the problem of the lack of an automatically compensating structure.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wind data acquisition device wind calibration mechanism, comprising a guide assembly and a shaft assembly. A compensation component is fitted onto the outer wall of the shaft assembly inside the guide assembly, and the outer wall of the compensation component is fixedly connected to the outer wall of the guide assembly. The compensation component includes a second bushing, with sealing plates fixedly connected to both ends of the second bushing. A compensation block is fixedly connected to the inner wall of the second bushing. The compensation block provides compensation and auxiliary support when a gap occurs between the second bushing and the inner bushing. By setting the compensation component, the problem of gaps easily forming at the bushing mating parts after long-term use can be solved. The gap-filling and auxiliary support functions of the compensation block can prevent wind calibration deviation caused by gaps, improving the wind calibration effect of the mechanism. Simultaneously, the sealing plates can prevent external sand, rainwater, and other impurities from entering the component, reducing component wear and extending the overall service life of the mechanism. Furthermore, the compensation component securely connects the shaft assembly and the guide assembly, enhancing the overall structural stability and reducing calibration errors caused by component loosening. The compensation block is made of steel.

[0009] Preferably, the shaft assembly includes a support rod, an arc-shaped support rod fixedly connected to the outer wall of the support rod, a first blocking cover fixedly connected to the outer wall of the support rod inside the arc-shaped support rod, a mounting plate fixedly connected to the outer wall below the support rod, an auxiliary rotating shaft fixedly connected to the outer wall of the support rod above the arc-shaped support rod, a speed measuring component fixedly connected to the inner wall of the support rod below the first blocking cover, and a second blocking cover fixedly connected to the outer wall of the support rod above the guide component. The arc-shaped support rod enhances the support strength of the support rod and prevents it from deforming due to long-term external force. This design ensures the overall structural stability of the shaft assembly; the first and second blocking covers provide double protection, protecting the areas above the speed measuring component and the guide component respectively, reducing the intrusion of impurities and ensuring the normal operation of internal components; the mounting plate provides a convenient installation method for the mechanism, reducing the assembly difficulty between the mechanism and the external carrier; the auxiliary rotating shaft reduces the resistance between the support rod and other rotating components, improving the rotational flexibility of the mechanism and avoiding lag in wind response due to excessive resistance; the speed measuring component is fixed to the inner wall of the support rod, ensuring its sensing position is stable and improving the accuracy of airflow data feedback.

[0010] Preferably, the guide assembly includes a crossbar, with a fan blade rotatably connected to the outer wall of one end of the crossbar, and a feather tail fixedly connected to the outer wall of the other end of the crossbar. The inner wall of the crossbar is fixedly connected to the outer wall of the second bushing. The fan blade has flexible rotation characteristics, which can quickly respond to changes in wind direction and drive the crossbar to adjust its direction in a timely manner, improving the mechanism's timeliness in responding to wind. The feather tail can stabilize the direction of the guide assembly, preventing the crossbar from frequently swaying due to airflow fluctuations and ensuring the stability of wind calibration. The fixed connection between the inner wall of the crossbar and the outer wall of the second bushing enables the guide assembly, compensation assembly, and shaft assembly to form a stable linkage, ensuring that the direction adjustment of the guide assembly can be transmitted to the entire mechanism, improving wind calibration. At the same time, the overall structure of the guide assembly is simple, and the connections of each component are reliable, reducing the maintenance difficulty of the mechanism.

[0011] Preferably, the speed measuring component includes a first bushing, with a sealing ring fixedly connected to the inner wall of the first bushing and a semi-circular shell fixedly connected to the outer wall of the first bushing. The semi-circular shell is arranged around the first bushing as an axis. The sealing ring can prevent external impurities from entering the interior of the first bushing, reducing wear on the internal components of the speed measuring component and extending its service life. It also prevents impurities from affecting the accuracy of airflow sensing. The semi-circular shell arranged around the first bushing as an axis can capture airflow from multiple directions, avoiding omissions or deviations in airflow data due to a single sensing direction, and improving the comprehensiveness and accuracy of airflow sensing. The stable fit between the first bushing and the inner wall of the support rod ensures the stability of the speed measuring component during operation, preventing positional shifts due to vibration, and further ensuring the reliability of airflow data. In addition, the components of the speed measuring component are easy to assemble, facilitating subsequent maintenance and replacement.

[0012] (III) Beneficial Effects

[0013] This utility model provides a wind calibration mechanism for a wind power data acquisition device. It has the following beneficial effects:

[0014] (i) The wind data acquisition device wind calibration mechanism uses a compensation component to fill the wear gap of the bushing to avoid directional transmission deviation. The first shield, the second shield, the sealing plate and the sealing ring prevent impurities from entering. This not only prevents the mechanism from becoming loose or the components from wearing due to external forces or impurities, but also extends the service life of each component and maintains the long-term stable operation of the mechanism.

[0015] (ii) The wind calibration mechanism of the wind data acquisition device provides a stable installation foundation through the support rod of the rod assembly. The arc-shaped support rod enhances its resistance to deformation. When the external airflow is applied, the fan blade of the guide assembly can quickly capture the wind direction and drive the crossbar to adjust the direction. The feather tail synchronously offsets the airflow fluctuation to stabilize the direction. The speed measurement component captures the airflow in multiple directions and feeds back the data. The collaboration of multiple components ensures the timeliness of the wind calibration of the wind data acquisition device. Attached Figure Description

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution for a wind calibration mechanism for a wind power data acquisition device: it includes a guide assembly 2 and a shaft assembly 1. The outer wall of the shaft assembly 1 located inside the guide assembly 2 is fitted with a compensation assembly 4, and the outer wall of the compensation assembly 4 is fixedly connected to the outer wall of the guide assembly 2. The compensation assembly 4 includes a second bushing 41, with sealing plates 42 fixedly connected to both ends of the second bushing 41. A compensation block 43 is fixedly connected to the inner wall of the second bushing 41. The compensation block 43 can compensate and provide auxiliary support when a gap occurs between the second bushing 41 and the inner bushing.

[0023] The shaft assembly 1 includes a support rod 11, an arc-shaped support rod 12 fixedly connected to the outer wall of the support rod 11, a first blocking cover 14 fixedly connected to the outer wall of the support rod 11 inside the arc-shaped support rod 12, a mounting plate 13 fixedly connected to the outer wall below the support rod 11, an auxiliary rotating shaft 15 fixedly connected to the outer wall of the support rod 11 above the arc-shaped support rod 12, a speed measuring component 3 fixedly connected to the inner wall of the support rod 11 below the first blocking cover 14, and a second blocking cover 16 fixedly connected to the outer wall of the support rod 11 above the guide component 2.

[0024] The guide assembly 2 includes a crossbar 21, with a fan blade 22 rotatably connected to the outer wall of one end of the crossbar 21, and a feather tail 23 fixedly connected to the outer wall of the other end of the crossbar 21. The inner wall of the crossbar 21 is fixedly connected to the outer wall of the second bushing 41.

[0025] The speed measuring component 3 includes a first bushing 31, a sealing ring 33 is fixedly connected to the inner wall of the first bushing 31, and a semi-circular shell 32 is fixedly connected to the outer wall of the first bushing 31. The semi-circular shell 32 is arranged around the first bushing 31 as the axis.

[0026] In use, when external airflow acts on the mechanism, the guide component 2 first triggers a wind response. The fan blades 22 in the guide component 2 rotate due to the impact of the airflow. Their flexible rotation characteristics can quickly capture changes in wind direction, thereby driving the connected crossbar 21 to rotate synchronously, so that the crossbar 21 is adjusted to face the direction of the airflow. At the same time, the feather tail 23 at the other end of the crossbar 21 plays a stabilizing role, using its own structural characteristics to offset the impact of airflow fluctuations on the crossbar 21, avoiding frequent shaking of the crossbar 21 due to unstable airflow, and ensuring that the crossbar 21 drives the guide component 2 to maintain a stable direction that matches the wind direction, thus completing the initial positioning of the wind direction.

[0027] After the guide assembly 2 completes the initial directional adjustment, it needs to transmit the directional adjustment action to the shaft assembly 1 to drive the entire wind calibration mechanism, including the wind power data acquisition device, to align with the wind synchronously. At this time, the compensation assembly 4 serves as the core of the connection between the guide assembly 2 and the shaft assembly 1. The two are stably connected through the second bushing 41. The inner wall of the second bushing 41 cooperates with the outer wall of the support rod 11 of the shaft assembly 1, and the outer wall is fixed to the inner wall of the crossbar 21, so that the directional adjustment force of the crossbar 21 can be directly transmitted to the support rod 11, causing the entire shaft assembly 1 to rotate synchronously with the direction of the guide assembly 2.

[0028] During long-term use, if the second bushing 41 and the internal support rod 11 experience wear gaps due to relative rotation, the compensation block 43 in the compensation component 4 will directly contact the support rod 11 to fill the gaps and provide auxiliary support to the support rod 11, preventing the gaps from widening further. In addition, the sealing plates 42 at both ends of the second bushing 41 can prevent external sand, rainwater and other impurities from entering the component mating parts, preventing impurities from aggravating gap wear, ensuring stable motion transmission between the guide component 2 and the shaft component 1, avoiding directional transmission deviations caused by gaps, and ensuring wind calibration accuracy.

[0029] The shaft assembly 1 plays a dual role in overall support and motion transmission during the operation of the mechanism. The core component, the support rod 11, provides the installation foundation and structural support for the guide assembly 2, the compensation assembly 4, and the speed measuring assembly 3. The arc-shaped support rod 12 on its outer wall enhances the deformation resistance of the support rod 11 through lateral support, preventing the support rod 11 from bending due to long-term bearing of component weight or airflow impact, thus ensuring the structural stability of the entire mechanism. The auxiliary rotating shaft 15 on the outer wall of the support rod 11 reduces the cooperation resistance between the support rod 11 and other rotating components, making the shaft assembly 1 drive the collector to rotate more smoothly and avoiding lag in wind response due to excessive resistance.

[0030] Meanwhile, the first blocking cover 14 and the second blocking cover 16 on the support rod 11 respectively protect the area above the speed measuring component 3 and the guide component 2 below, preventing impurities such as falling objects and sand from entering the internal components, ensuring the normal operation of the speed measuring component 3 and the guide component 2, and indirectly providing support for the stability of wind calibration. The mounting plate 13 below the support rod 11, by fixing it to the external carrier, ensures that the entire mechanism will not be displaced by airflow impact during operation, providing a stable installation foundation for wind calibration.

[0031] While the mechanism completes the directional adjustment, the speed measuring component 3 senses the airflow status in real time, providing data support for wind calibration. The semi-circular shell 32 in the speed measuring component 3 is arranged around the first bushing 31 as the axis, which can capture the flow status of the airflow from multiple directions and feed back the sensed airflow data to the control unit of the wind power data acquisition unit. The stable fit between the first bushing 31 and the inner wall of the support rod 11 ensures that the semi-circular shell 32 will not shift due to vibration under the impact of airflow, ensuring the accuracy of the airflow data. At the same time, the sealing ring 33 on the inner wall of the first bushing 31 can prevent impurities from entering the interior of the speed measuring component 3, avoiding impurities from affecting the sensing sensitivity of the semi-circular shell 32, and further ensuring the reliability of data feedback.
