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.

[0023] The purpose of this invention is to provide a turbulent probe attitude-assisted positioning device to solve the problems existing in the prior art and to conveniently and quickly achieve accurate positioning of the turbulent probe attitude.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] This embodiment provides a turbulent probe attitude-assisted positioning device, such as... Figure 1 and Figure 2 As shown, it includes an L-shaped body 10, which has a slot 13 and a level 20 is fixedly mounted on the L-shaped body 10. The slot 13 is used to fix and hold a turbulence probe, and the turbulence probe placed in the slot 13 is coaxial with the slot 13. When the level 20 is in a horizontal state, the axis of the slot 13 is vertical.

[0027] By placing the turbulence probe in the slot 13 of the L-shaped body 10, the turbulence probe can be more quickly and conveniently fixedly connected to the L-shaped body 10 due to the setting of the slot 13; by calibrating its vertical attitude with the bubble level 20, the turbulence probe can maintain its vertical attitude during use, thereby making the data measured by the turbulence probe more accurate, especially the wind direction angle and wind deflection angle data.

[0028] The structural design of the L-shaped body 10 is described below:

[0029] Specifically, during use, the L-shaped body 10 is directly fixed to the turbulence probe, which is then fixed by a bracket or robotic arm.

[0030] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the L-shaped body 10 includes a vertical fixing block 11 and a flat platform 12; one end of the flat platform 12 is fixed to the upper side of the vertical fixing block 11; a slot 13 is provided on the vertical fixing block 11; a spirit level 20 is fixedly mounted on the upper surface of the flat platform 12. The L-shaped body 10 is composed of a vertical fixing block 11 and a flat platform 12. This structural design is simple and stable. The vertical fixing block 11 is used to open the slot 13 to fix the turbulence probe, while the flat platform 12 provides an installation surface for the spirit level 20. The combination of the two makes the structure of the entire device compact, which is convenient for installation and operation. The slot 13 on the vertical fixing block 11 is used to fix the turbulence probe. Since the slot 13 is coaxial with the turbulence probe, it can ensure the accurate positioning of the turbulence probe in the vertical direction, while the spirit level 20 on the flat platform 12 can intuitively show whether it is in a horizontal state.

[0031] In the optional solutions of this embodiment, it is more preferred that the vertical fixing block 11 and the flat platform 12 are integrally formed. Integral forming avoids the weak points that may occur in the connection between the vertical fixing block 11 and the flat platform 12 due to splicing, welding or bolting, and there is no risk of connection gaps or loosening, making the structure of the entire L-shaped body 10 more robust and durable. Since integral forming eliminates the positional deviation caused by the connection process, the relative positional accuracy between the vertical fixing block 11 and the flat platform 12 is higher, that is, the accuracy of the bubble level 20 can directly reflect the verticality of the axis of the slot 13 on the vertical fixing block 11.

[0032] The following are the settings instructions for the bubble level 20:

[0033] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, the upper surface of the bubble level 20 is a transparent window, through which the bubble inside the bubble level 20 can be seen. A centering marker ring 21 is provided on the transparent window. When the bubble inside the bubble level 20 is centered within the centering marker ring 21, the axis of the slot 13 is vertical. The centering marker ring 21 on the transparent window provides a clear visual reference standard for the centering of the bubble. When the bubble inside the bubble level 20 is accurately located within the centering marker ring 21, it can be intuitively and accurately determined that the bubble level 20 is in a horizontal state, thus ensuring that the axis of the slot 13 is vertical, making the positioning of the turbulence probe more accurate. Observing whether the bubble is within the centering marker ring 21 through the transparent window is a simple and easy-to-understand operation method that even inexperienced operators can quickly master.

[0034] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 As shown, a crosshair 22 is also provided on the transparent window, and the crosshair 22 is concentric with the centering mark circle 21. The crosshair 22 provides a more precise visual reference. When adjusting the position of the bubble in the bubble level 20, the operator can more accurately judge whether the bubble is completely centered. Compared with only the centering mark circle 21, the horizontal and vertical lines of the crosshair 22 can help the operator align the bubble more accurately in both horizontal and vertical directions, so that the bubble is not only within the mark circle, but also precisely at the cross intersection. This further ensures that the axis of the slot 13 is strictly vertical, improves the accuracy of the turbulence probe attitude positioning, and is conducive to obtaining more accurate and reliable measurement data. In actual operation, especially in poor lighting conditions or when the observation angle is limited, the crosshair 22 is easier to quickly identify and refer to.

[0035] To further enhance the stability of the turbulent probe, the following settings can also be implemented:

[0036] In the optional embodiments of this example, a preferred embodiment is that an anti-slip layer is fixedly provided on the inner wall of the slot 13. The anti-slip layer can significantly increase the friction between the inner wall of the slot 13 and the turbulence probe. During the measurement process, the turbulence probe may be subjected to various external forces, such as airflow impact and slight vibration. The anti-slip layer can effectively prevent the turbulence probe from sliding or shifting within the slot 13, ensuring that the turbulence probe always remains in the accurate installation position, thereby guaranteeing the accuracy and reliability of the measurement data.

[0037] In the optional solutions of this embodiment, the anti-slip layer is preferably formed by an elastic rubber layer or multiple anti-slip protrusions. The elastic rubber layer is soft and elastic, which can effectively buffer the collision and compression between the probe and the slot 13 when installing the turbulence probe, and avoid scratches, wear and other damage to the probe surface due to direct contact with the hard inner wall of the slot 13. It plays a good protective role for the relatively precise turbulence probe and extends its service life. The multiple anti-slip protrusions increase the surface roughness of the inner wall of the slot 13. When in contact with the surface of the turbulence probe, the protrusions can be embedded into the small grooves or irregularities on the probe surface to form a mechanical engagement, thereby significantly increasing the friction. This structural design can more effectively prevent the probe from sliding relative to the slot 13, and is especially suitable for measurement scenarios that need to withstand large external forces.

[0038] In the optional solutions of this embodiment, it is more preferred that at least one retaining ring for fixing the turbulence probe can be sleeved on the outer side of the slot 13 (specifically the outer side of the vertical fixing block 11). (The retaining ring is an existing structure that can be fixedly sleeved on the outside of the turbulence probe, such as a ring hoop; it can be directly sleeved on the outer side of the vertical fixing block 11, or the retaining ring can be a semi-circular ring with one end rotatably connected to the outer wall of the vertical fixing block 11, and a snap-fit ​​part is provided on the outer wall of the vertical fixing block 11 corresponding to the free end position of the semi-circular ring. The free end of the semi-circular ring is provided with a hook, which can snap into the snap-fit ​​part. The snap-fit ​​part is an existing structure for snapping into the hook, which will not be described in detail here. The semi-circular ring can close the opening of the slot 13.) The retaining ring provides additional clamping force, further ensuring that the turbulence probe is firmly fixed in the retaining groove 13. Even when subjected to strong airflow impact, vibration or other external forces, the retaining ring can effectively prevent the probe from loosening or shifting, ensuring the stability of the probe posture during the measurement process, thereby improving the accuracy and reliability of the measurement data.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
