Technical Field

[0001] This application relates to the field of wind speed testing equipment technology, and in particular to a wind speed meter fixing device. Background Technology

[0002] In the field of smoke box wind speed measurement, handheld anemometers are a commonly used measuring tool. Their main advantages are portability and flexibility, enabling rapid acquisition of wind speed data. However, in actual measurement, since the operation of handheld anemometers usually relies on manual control, improper manual operation can lead to significant errors in the measurement results. Therefore, a fixing device for the anemometer is needed to secure it for wind speed measurement.

However, this method relies on ground support and magnetic adsorption, involves many components, has a complex structure, and is costly. Therefore, there is an urgent need for a low-cost anemometer mounting device. Utility Model Content

[0012] Optionally, the through-hole cylindrical structure coincides with the central axis of the two concentric cylindrical structures, and the diameter of the through-hole cylindrical structure is larger than the outer diameter of the screw, so that the screw passes perpendicularly through the base.

[0013] Optionally, the outer circumferential surface of the rotating component is provided with a reference scale line, and the limiting component is provided with multiple angle scale lines, so that the reference scale line is aligned with any one of the multiple angle scale lines to read the rotation angle.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0036] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] The following describes the relevant content, concepts, meanings, technical issues, technical solutions, and beneficial effects involved in the embodiments of this application.

[0039] First, let me explain some of the terms used in this application:

[0040] A smoke chamber is a closed or semi-closed cavity used for testing. It has a structure inside that can measure the internal wind speed (such as a reserved measurement port). When it is necessary to measure parameters such as wind speed and airflow distribution inside the smoke chamber, an anemometer can be inserted into it through the reserved measurement port. When it is necessary to measure parameters such as wind speed and airflow distribution at the air outlet of the smoke chamber, the anemometer can be placed directly at the air outlet for measurement.

[0041] An anemometer is an instrument used to measure the speed of airflow (i.e., wind speed). It is widely used in meteorological observation, environmental monitoring, industrial production, aerospace, agriculture, and many other fields. An anemometer consists of a probe and a measuring rod. The probe is used to contact the airflow and convert the wind speed into a measurable physical signal. The measuring rod is used to connect the probe and provides support, ensuring that the probe is in the preset measurement position.

[0042] Example 1

[0043] Embodiment 1 of this application provides a wind speed meter fixing device; please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic diagram of a wind speed meter fixing device according to Embodiment 1 of this application. The wind speed meter fixing device provided in Embodiment 1 of this application may specifically include the following components: base 10, rotating component 30, limiting component 20, screw component 50, fixing component 40, etc. The specific functions and structure are shown below:

[0044] Base 10: Base 10 serves as the mounting base and support carrier for the anemometer fixing device. Its bottom can be integrated with a mounting positioning structure. This structure can be in the form of a magnetic component or a threaded interface, used to detachably fix the anemometer fixing device to the surface of the target object (such as a cigarette box). The mounting positioning structure can ensure that the central axis of base 10 is perpendicular to the surface of the target object and ensure the stability of the anemometer fixing device.

[0045] The base 10 is provided with a through-hole cylindrical structure that runs along the central axis. The inner diameter of the through-hole cylindrical structure is larger than the outer diameter of the screw 50. The two form a clearance fit to form a guide channel, which can constrain the screw 50 to move only along the axial direction. This ensures that the probe of the target anemometer inside the screw 50 is always perpendicular to the surface of the target object to be measured, eliminating the measurement angle deviation caused by radial offset.

[0046] Meanwhile, two concentric cylindrical structures are provided around the through-hole cylindrical structure. These concentric cylindrical structures form a high-precision clearance fit with the inner hole of the rotating part 30 (such as a fit clearance of 0.01-0.03mm). This provides the rotating part 30 with a 360° circumferential rotation freedom, and the guiding effect of the concentric cylindrical structures ensures that the rotation axis of the rotating part 30 coincides with the central axis of the base 10, thus ensuring the coaxiality of each component during rotation.

[0047] A ring-shaped support platform is provided on the base 10. This ring-shaped support platform can fit into the ring-shaped pressure plate at the bottom of the rotating component 30 to provide axial support for the rotating component 30. The flatness error of the ring-shaped support platform is controlled within a preset error (e.g., 0.02mm / m, meaning the height difference between one plane and another within a 1m range is 0.02mm). This can reduce the planar friction resistance when the rotating component 30 rotates. Combined with the axial clamping effect of the limiting component 20, the rotating component 30 is limited to the ring-shaped support platform, effectively preventing axial movement of the rotating component 30 during circumferential rotation or adjustment of the screw component 50, and improving the overall structural stability of the anemometer fixing device.

[0048] Rotating component 30: The rotating component 30 serves as the angle adjustment component of the anemometer fixing device. Its main body is a hollow rotating structure, which is used to be fitted onto the concentric cylindrical structure of the base 10. It can rotate 360° horizontally around the central axis of the base 10.

[0049] The inner wall of the top of the rotating part 30 is provided with an internal thread, which can form a threaded pair with the external thread of the screw part 50. The height of the screw part 50 can be adjusted by rotation. Both the internal thread of the rotating part 30 and the external thread of the screw part 50 can be designed with fine threads (such as pitch ≤ 0.5mm) to achieve high-precision adjustment and meet the needs of different depth measurements.

[0050] The outer circumferential surface of the rotating component 30 is provided with reference scale lines, which, in conjunction with the angle scale lines of the limiting component 20, can accurately read the rotation angle of the rotating component 30. For example, 360 angle scale lines can be evenly distributed on the limiting component 20, with a graduation value of 1°, to achieve accurate rotation angle readings and meet the precision measurement requirements of the probe angle calibration of the target anemometer.

[0051] The bottom of the rotating component 30 is designed as an annular bearing platform, which works in conjunction with the annular support platform of the base 10 and the fixing platform of the limiting component 20. This ensures the smooth rotation of the rotating component 30 and prevents axial movement, thereby improving the structural stability of the anemometer fixing device.

[0052] Limiting component 20: The inner wall thread of the limiting component 20 is fastened to the outer thread of the base 10 to achieve fixation with the base 10.

[0053] The limiting member 20 includes a fixed platform that forms a surface contact with the annular bearing platform of the rotating member 30, axially pressing the rotating member 30 against the annular support platform of the base 10, and allowing the rotating member 30 to retain only the horizontal rotational freedom around the central axis, which can effectively suppress the axial movement of the screw member 50 during adjustment or measurement.

[0054] An angle scale is provided around the outer circumference of the limiting member 20 or the top of the fixed platform, which cooperates with the reference scale of the rotating member 30 to achieve accurate reading of the rotation angle. The angle scale is evenly distributed around the circumference (e.g., one scale every 1°, one marking line every 10°), with a minimum division value of 1°. The rotation angle of the rotating member 30 can be accurately read by aligning the angle scale with the reference scale.

[0055] The inner hole of the limiting member 20 cooperates with the concentric cylindrical structure of the base 10 to control the stability of the outer cylindrical surface of the rotating member 30, further ensuring the coaxiality of each component in the anemometer fixing device, and improving the structural stability and measurement reliability of the anemometer fixing device under vibration environment.

[0056] Screw 50: The screw 50 serves as the load-bearing and positioning component of the target anemometer. It has an axial through-hole with the inner wall of the hole. The axis of the inner wall of the hole coincides with the central axis of the screw 50, ensuring that the anemometer probe housed in the hole always measures along the axial direction (perpendicular to the surface of the target object), effectively eliminating the angle measurement error caused by radial deviation.

[0057] The inner wall of the through-hole is integrated with an elastic clamping structure, which consists of at least two pairs of elastic components (such as copper alloy clips or silicone pads) symmetrically distributed along the circumference. Through elastic deformation, it can adaptively clamp the measuring rods of different models of anemometers, such as anemometer measuring rods of different specifications with diameters of 5-15mm.

[0058] The outer circumferential surface of the screw 50 has an external thread, which forms a threaded pair with the thread on the inner wall of the top of the rotating part 30. The axial feed motion is achieved through the thread engagement of the two. When the rotating part 30 rotates relative to the base 10, the screw 50 moves axially under the guidance of the thread, which drives the anemometer probe to accurately adjust the depth of its insertion into the smoke box to meet the depth control requirements of different measurement points.

[0059] The screw 50 has a limiting cylinder at its top, which can effectively prevent the screw 50 from detaching from the rotating part 30 due to excessive screwing. This structurally avoids the risk of parts falling off during operation and improves the safety of the device.

[0060] Fixing component 40: The fixing component 40 adopts a nut-type structure design, and its inner wall is machined with an internal thread that matches the external thread of the screw component 50, forming a detachable helical pair. After the screw component 50 is adjusted axially to the preset height, the fixing component 40 is tightened so that its first end face (locking end face) close to the rotating component 30 is tightly fitted with the top plane of the rotating component 30. The preload of the helical pair and the friction between the first end face and the top surface of the rotating component 30 are used to rigidly lock the relative axial position of the screw component 50 and the rotating component 30, effectively suppressing the height deviation of the screw component 50 caused by vibration, airflow disturbance or external force during the measurement process, and ensuring the depth positioning accuracy of the anemometer probe.

[0061] The preset height refers to the axial depth at which the anemometer probe needs to be inserted into the smoke box, which is planned in advance according to the measurement requirements. This height is related to the length of the screw component. By rotating the screw component 50 and adjusting its axial extension length through the external thread of the screw component 50 and the thread of the rotating component 30, the probe can reach the corresponding depth, thereby achieving accurate measurement of airflow at different positions inside the smoke box.

[0062] The outer circumferential surface of the fastener 40 may be provided with anti-slip texture to increase friction during manual operation, enabling quick tightening and loosening and improving the convenience of on-site adjustment. In the locked state, the contact area ratio between the first end face and the top surface of the rotating part 30 is greater than the preset area ratio (e.g., 80%), ensuring uniform pressure distribution and avoiding local stress concentration that could lead to plastic deformation of the thread profile of the fastener 40 or wear on the top surface of the rotating part 30, thereby extending the service life of the threaded pair and related components.

[0063] It is evident that by coordinating the various components of the anemometer fixing device, the target anemometer can be accurately positioned, stably fixed, and flexibly adjusted, effectively solving the error problem caused by non-standard operation in traditional handheld measurements and improving the accuracy and efficiency of smoke box wind speed measurement.

[0064] Example 2

[0065] Embodiment 2 of this application provides a wind speed meter fixing device. Please refer to [link / reference]. Figure 2 , Figure 2 This is an assembly diagram of an anemometer fixing device provided in Embodiment 2 of this application. The anemometer fixing device provided in Embodiment 2 of this application may specifically include the following components: base 10, rotating part 30, limiting part 20, screw part 50, fixing part 40, etc.

[0066] The rotating component 30, the limiting component 20, the screw component 50, and the fixing component 40 are arranged coaxially along the central axis of the base 10;

[0067] The inner thread of the limiting member 20 is connected to the outer thread of the base 10 to limit the rotating member 30 on the base 10.

[0068] The internal thread at the top of the rotating member 30 engages with the thread of the screw member 50, allowing the screw member 50 to be adjusted up and down along the axial direction of the rotating member 30. Furthermore, the fixing member 40 engages with the thread of the screw member 50, fixing the screw member 50 onto the rotating member 30.

[0069] The screw component 50 has a through-hole inner wall, which is used to place the target anemometer, and the target anemometer is used to measure wind speed.

[0070] When using the anemometer fixing device, the target anemometer is placed in the inner wall of the through hole of the screw member 50. After the screw member 50 is adjusted to a preset height on the rotating member 30, the fixing member 40 is tightened so that its first end face abuts against the surface of the rotating member 30. The rotating member 30 is limited on the base 10 by the limiting member 20 so that the target anemometer can accurately measure the wind speed.

[0071] Please see Figure 3 , Figure 3 The figure shows a schematic diagram of a base provided in Embodiment 2 of this application. The base 10 includes a through-hole cylindrical structure 101, two concentric cylindrical structures 102, a support platform 103, an external thread 104, and a base chassis 105 arranged coaxially in sequence.

[0072] The through-hole cylindrical structure 101 runs through the central axis of the base, and the diameter of the through-hole cylindrical structure 101 is larger than the outer diameter of the screw 50. It is used to provide a vertical guide channel for the screw 50 so that the screw 50 passes vertically through the base 10, so as to ensure that the target anemometer probe can extend into the space to be measured along the axis.

[0073] The central axis of the through-hole cylindrical structure 101 coincides with that of the two concentric cylindrical structures 102. The two concentric cylindrical structures 102 can form a clearance fit with the inner hole of the rotating part 30, enabling the rotating part 30 to rotate 360° while ensuring coaxiality during rotation.

[0074] The support platform 103 is used to support the rotating component 30 and, together with the limiting component 20, axially limits the rotating component 30 to prevent it from moving up and down. Specifically, the external thread 104 of the base and the internal thread of the limiting component 20 can form a threaded pair. When the limiting component 20 is tightened on the base 10, the axial limitation of the rotating component 30 is achieved.

[0075] The bottom of the base chassis 105 may be provided with an installation structure, which includes a magnetic base or a threaded mounting hole. Therefore, the anemometer fixing device can be fixed to the surface of the target object by means of the magnetic base or the threaded mounting hole, providing a stable support foundation for the anemometer fixing device. Moreover, the central axis of the base 10 is perpendicular to the surface of the target object, ensuring the installation stability and measurement reliability of the anemometer fixing device.

[0076] Please see Figure 4a and Figure 4b , Figure 4a This is a first-view structural schematic diagram of a limiting component provided in Embodiment 2 of this application. Figure 4b This is a second-view structural schematic diagram of a limiting member provided in Embodiment 2 of this application, combined with... Figure 4a and Figure 4bThe limiting component 20 includes an angle scale line 201, a threaded inner wall of the limiting component 202, and a fixed platform 203.

[0077] The limiting component 20 has an overall ring-shaped rotating structure with multiple angle scale lines 201 evenly distributed around its circumference (only one is shown in the figure as an example; in practice, the scale lines can be set according to the measurement accuracy requirements, such as arranging them at equal intervals of 1° or 2°). These scale lines are used to cooperate with the reference scale lines of the rotating component 30, providing a visual and precise reading basis for the 360° rotation angle adjustment of the rotating component 30, and ensuring the consistency and accuracy of the anemometer probe angle adjustment.

[0078] The inner wall thread 202 of the limiting component is an internal thread structure, which is adapted to the outer thread 104 of the base 10. The limiting component 20 and the base 10 are rigidly fastened through the threaded connection, and the axial preload transmission path is provided for the fixed platform 203.

[0079] The fixed platform 203 is the annular end face of the limiting member 20 facing the rotating member 30, which corresponds to and cooperates with the annular bearing platform of the rotating member 30. Under the action of thread pre-tightening, an axial clamping force is applied to the rotating member 30, which limits the rotating member 30 between the support platform 103 of the base 10 and the fixed platform 203. Only the circumferential rotational freedom of the rotating member 30 around the central axis of the base 10 is retained, which effectively suppresses the axial movement of the rotating member 30, improves the overall structural stability of the anemometer fixing device, and ensures that the attitude is controllable during the anemometer measurement process.

[0080] Please see Figure 5a and Figure 5b , Figure 5a This is a first-view structural schematic diagram of a rotating component provided in Embodiment 2 of this application. Figure 5b This is a structural schematic diagram from a second perspective of a rotating component provided in Embodiment 2 of this application, combined with... Figure 5a and Figure 5b The rotating component 30 includes an internal thread 301 at the top, a reference scale line 302, an annular pressure plate 303, and a hollow rotating structure 304. The rotating component 30 is used to adjust the angle and height of the target anemometer.

[0081] The top internal thread 301 is located in the hollow area at the top of the rotating part. It can form a helical pair with the thread of the screw 50, which can convert the circumferential rotation of the rotating part 30 into the axial linear motion of the screw 50, so that the screw 50 can be adjusted up and down along the axial direction of the rotating part 30.

[0082] A reference scale line 302 is set on the outer circumferential surface of the rotating component 30, serving as a reference mark for angle measurement. The reference scale line 302 can cooperate with the circumferentially distributed angle scale lines of the limiting component 20 to form an angle indicating system. When the rotating component 30 rotates around the central axis of the base 10, the rotation angle of the rotating component 30 can be accurately read by aligning the reference scale line 302 with the circumferentially distributed angle scale lines of the limiting component 20. The rotating component 30 ensures that the target anemometer is perpendicular to the airflow direction, eliminating the influence of angular deviation on the measurement data.

[0083] The annular bearing platform 303 is an annular end face structure at the bottom of the rotating component 30. It can cooperate with the support platform 103 of the base 10 and the fixing platform 203 of the limiting component 20 to form an axial limiting constraint under the thread preload of the limiting component 20. The annular bearing platform 303 can restrict the axial movement of the rotating component 30, retaining only the circumferential rotational degree of freedom. At the same time, it disperses the preload through surface contact, avoiding structural deformation caused by local stress concentration and improving the long-term reliability of the anemometer fixing device.

[0084] The hollow rotating body structure 304 serves as the main frame of the rotating component 30. Its inner hole forms a clearance fit with the two concentric cylindrical structures 102 of the base 10 (the fit clearance can be 0.02-0.05mm), providing radial guidance for the rotating component 30 to constrain its radial runout. For example, the radial runout of the rotating component 30 is constrained to be less than or equal to 0.03mm, ensuring that the rotating component 30 rotates 360° around the central axis of the base 10 without jamming, ensuring the coaxiality of the screw component 50 and the base 10, and avoiding measurement errors caused by radial offset of the target anemometer.

[0085] Please see Figure 6 , Figure 6 The figure shows a structural schematic diagram of a fastener provided in Embodiment 2 of this application. As shown, the fastener 40 includes a fastener thread 401.

[0086] The fixing component 40 adopts a hexagonal nut configuration, and its central hole has a fixing thread 401 machined on its inner wall, which is compatible with the external thread of the screw component 50. After the screw component 50 is adjusted to the preset height, the fixing component 40 is tightened, and the thread preload is used to make the first end face of the fixing component 40 fit tightly with the top surface of the rotating component. Through the synergistic effect of the thread friction and the end face support force, the relative axial position of the screw component 50 and the rotating component 30 is locked, suppressing the displacement of the screw component 50 caused by vibration and external force during the measurement process, and ensuring the stability of the target anemometer.

[0087] The hexagonal shape of the fastener 40, combined with the surface anti-slip treatment (such as knurling, chamfering and deburring), facilitates manual operation and allows for quick locking and unlocking without special tools, meeting the needs of convenient on-site debugging. At the same time, the reasonable thread profile and pitch design can balance the distribution of preload, avoid plastic deformation of the thread pair due to stress concentration, and improve the service life of the device.

[0088] Please see Figure 7 , Figure 7 The figure shows a schematic diagram of a screw component provided in Embodiment 2 of this application. The screw component 50 includes an external thread 501, an inner wall of a through hole 502, and a limiting cylinder 503.

[0089] The external thread 501 of the screw component is machined along the outer circumferential surface of the main body of the screw component 50, and adopts a standard thread profile (such as fine thread or trapezoidal thread), which mates with the internal thread 301 at the top of the rotating component 30 to form a threaded pair. Through rotation operation, the circumferential motion can be converted into the axial linear displacement of the screw component 50, accurately controlling the depth of the target anemometer rod and probe extending into the measurement area (such as the smoke box), and meeting the depth adaptation requirements of different measurement points.

[0090] Please see Figure 8 , Figure 8 This is a schematic diagram of the internal structure of a screw component provided in Embodiment 2 of this application. As shown in the figure, the inner wall 502 of the through-hole is the inner wall of the central cavity through which the screw component 50 is axially connected. Its diameter is adapted to the measuring rod diameter of common anemometers, and the inner wall can integrate an elastic clamping structure 504 (which can be in the form of an elastic metal spring, silicone bushing, etc.). Figure 8 For structural illustration purposes, the form of the elastic clamping structure 504 and its height within the inner wall 502 of the through-hole can be configured as needed in actual applications. This elastic clamping structure 504 utilizes the clamping force generated by elastic deformation to adaptively clamp measuring rods of different specifications, ensuring the coaxiality of the measuring rod of the target anemometer with the screw component 50. This avoids measuring rod slippage affecting measurement accuracy and is compatible with multiple anemometer models, improving component versatility.

[0091] The limiting cylinder 503 is an integrally formed cylindrical structure at the top of the screw 50. Its outer diameter is larger than the minor diameter of the internal thread 301 at the top of the rotating part 30. Alternatively, the cylindrical structure may not include a threaded structure, thus preventing rotation. When the screw 50 is adjusted axially to its limit position (the position of the limiting cylinder 503, which is also the topmost point), the limiting cylinder 503 contacts the end face of the rotating part 30, forming a mechanical limit. This prevents the screw 50 from detaching from the rotating part 30 due to excessive screwing, thus mitigating the risk of component detachment during measurement from a structural perspective and ensuring the operational safety of the anemometer fixing device and the stable attitude of the target anemometer.

[0092] Optionally, a wear-resistant gasket is provided between the support platform 103 of the base 10 and the annular pressure plate 303 of the rotating component 30. This wear-resistant gasket can prevent the support platform 103 from directly contacting the annular pressure plate 303, reduce wear, and improve the service life of the components.

[0093] Optionally, a planar bearing structure is provided between the fixed platform 203 of the limiting member 20 and the annular bearing platform 303 of the rotating member 30. The planar bearing structure includes a needle roller or ball roller assembly to reduce the rotational resistance of the rotating member 30 and ensure that the rotating member 30 is stable and does not wobble on the horizontal plane.

[0094] As can be seen, the constructed anemometer fixing device, through the coordinated operation of the base 10, rotating component 30, limiting component 20, fixing component 40 and screw component 50, achieves low-cost precise control of the anemometer depth and angle, ensures stable operation of the anemometer, and improves data reliability.

[0095] Example 3

[0096] Embodiment 3 of this application provides an application scenario for an anemometer fixing device. Please refer to [link / reference]. Figure 9 , Figure 9 This figure shows an application scenario of an anemometer mounting device provided in Embodiment 3 of this application. As shown, this application scenario focuses on wind speed measurement inside a smoke box.

[0097] The smoke box has a circular hole on its surface for the target anemometer to insert into. The base of the anemometer fixing device is securely attached to the smoke box through an installation structure, ensuring the support stability of the anemometer fixing device. The target anemometer is fixed in the inner wall of the through-hole by the elastic clamping structure of the screw, and the target anemometer is inserted into the smoke box through the through-hole cylindrical structure of the base to measure the wind speed.

[0098] The adjustment structure, composed of rotating and screw components, provides multi-dimensional freedom for adjusting the spatial position of the target anemometer. For example, the threaded engagement between the screw and the rotating component allows for depth adjustment. The airflow field inside the smoke chamber exhibits stratification, with differences in wind speed and flow pattern at different depths. Through rotation, the screw moves axially, precisely inserting the anemometer probe into different depth regions within the smoke chamber. For instance, in a scenario verifying airflow uniformity within the smoke chamber, the probe can be sequentially adjusted to positions 5cm, 10cm, and 15cm from the inner wall of the smoke chamber (the maximum depth is preset based on the screw length), collecting wind speed data at each depth to analyze the longitudinal distribution of airflow within the smoke chamber. The top limiting cylinder prevents the screw from excessively unscrewing and detaching from the rotating component, ensuring the structural integrity of the device and operator safety during operation.

[0099] Although the airflow inside the smoke chamber has a general direction, local eddies and turbulence may exist, and the orientation of the anemometer probe directly affects the measurement accuracy. The limiting and rotating components work together to adjust the angle, precisely controlling the orientation of the probe on the target anemometer in the horizontal plane. Operators can determine the orientation based on the general direction of the airflow inside the smoke chamber (e.g., ...). Figure 9 (As indicated by the middle arrow, the airflow direction) is aligned with the angle of the rotating and limiting components to ensure that the probe's frontal surface is perpendicular to the airflow direction, minimizing measurement errors caused by angular deviations. If the angle is not precisely calibrated, probe tilt may cause the measured wind speed value to deviate from the true value. This is especially problematic in scenarios where airflow uniformity is critical, such as cigarette production, where angular errors can have a cascading impact on product quality. The angle adjustment function of this anemometer fixing device effectively mitigates this risk.

[0100] Please see Figure 10 , Figure 10 This is an application scenario diagram of another anemometer mounting device provided in Embodiment 3 of this application. As shown in the figure, this application scenario focuses on wind speed measurement operations outside the smoke box.

[0101] The target anemometer is fixed to the surface of the object to be measured outside the smoke box (which can be an extension of the smoke box) using the anemometer fixing device of Embodiment 3 of this application. The probe of the target anemometer faces the smoke box and is precisely aligned with the airflow interaction area on the smoke box surface. With the anemometer fixing device, the probe of the target anemometer is stably suspended outside the smoke box in the measurement area. The operator can align the probe of the target anemometer with the mainstream airflow direction of the smoke box (e.g., by adjusting the angle of the rotating and limiting components) using the anemometer fixing device. Figure 10 (The airflow direction is indicated by the middle arrow), which allows for real-time monitoring of wind speed and airflow direction near the surface of the smoke box.

[0102] As can be seen, the anemometer fixing device of Embodiment 3 of this application can not only be used for measuring complex flow fields inside the smoke box, but also play an advantage of precise fixing and multi-dimensional adjustment in simple flow field monitoring outside the smoke box.

[0103] Therefore, the anemometer fixing device in Embodiment 3 of this application solves the problem of unstable anemometer fixing in traditional smoke box measurement methods, which easily leads to displacement and shaking under airflow impact, resulting in large fluctuations and poor repeatability of measurement data. The anemometer fixing device in Embodiment 3 of this application, through the stable installation of the base, the clamping and fixing of the screw components, and the anti-detachment design of the limiting structure, ensures that the target anemometer maintains a stable posture in the complex airflow environment of the smoke box. At the same time, the multi-dimensional adjustment function allows operators to flexibly set the measurement points according to the size of the smoke box and the airflow characteristics, eliminating the need for frequent disassembly and reinstallation of the anemometer, significantly improving measurement efficiency.
