Description

Technical Field

[0001] This utility model relates to the field of wind tunnel correction technology, and in particular to a wind tunnel direction corrector. Background Technology

[0002] Wind tunnel testing is an indispensable part of many fields, including aerodynamics research, aerospace vehicle design, and automotive engineering. In wind tunnel testing, simulating the real airflow environment is crucial for obtaining accurate and reliable data. The wind tunnel direction corrector, a key piece of equipment in wind tunnel testing, is primarily responsible for adjusting and correcting the direction of airflow within the wind tunnel to ensure that the test conditions are as close to ideal as possible. The accuracy of airflow direction is critical for obtaining precise experimental data in wind tunnel testing. The main function of the wind tunnel direction corrector is to adjust and correct the direction of airflow within the wind tunnel, making it as close as possible to the ideal state required for the test.

[0003] However, traditional wind tunnel orientation correctors have significant shortcomings in probe adjustment. Traditional wind tunnel orientation correctors typically employ fixed or mechanical adjustment mechanisms, which are often cumbersome to operate and difficult to control precisely when adjusting the probe angle and height. Furthermore, components such as linkages in traditional correctors are prone to disturbance in the airflow, affecting the accuracy of measurement data. These limitations are particularly pronounced in scenarios requiring frequent probe position adjustments to adapt to different experimental needs.

[0004] Therefore, developing a wind tunnel orientation corrector that can conveniently and quickly adjust the probe angle and height while reducing airflow disturbance is of great significance for improving the efficiency and accuracy of wind tunnel tests. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to propose a wind tunnel direction corrector, which aims to at least solve the technical problems in the related technologies, such as the cumbersome operation of traditional probes during use, the difficulty in achieving precise control, and the impact on the accuracy of measurement data.

[0006] To achieve the above objectives, this utility model proposes a wind tunnel orientation corrector, which includes:

[0007] Mounting rack;

[0008] The mounting plate is vertically and retractably connected to the mounting frame, and a sliding plate is slidably connected to the mounting plate;

[0009] The locking mechanism includes a locking band, a limiting wheel, and a locking motor. The locking motor is fixedly connected to the sliding plate and is driven by the locking band.

[0010] A probe that allows for a locking connection between the locking band and the limiting wheel;

[0011] The probe is allowed to move up and down with the mounting plate, and the locking band can be used to drive the probe to rotate.

[0012] In one embodiment of this utility model, a lifting mechanism is provided on the mounting frame, and the lifting mechanism is connected to the mounting plate;

[0013] The lifting mechanism includes:

[0014] The lifting motor is fixedly connected to the top of the mounting bracket;

[0015] The lifting screw is rotatably connected within the mounting frame, and the lifting screw is drive-connected to the lifting motor;

[0016] The slider is slidably connected within the mounting frame and is connected in cooperation with the lifting screw;

[0017] The mounting plate is fixedly connected to the slider.

[0018] In one embodiment of this utility model, a locking bolt is also included, which is located between the mounting plate and the sliding plate;

[0019] The mounting plate has a slot on its side, and the locking bolt is slidably connected in the slot.

[0020] The end of the locking bolt is threaded onto the slide plate.

[0021] In one embodiment of this utility model, one end of the mounting plate is provided with an opening, and two sets of limiting wheels are provided;

[0028] In one embodiment of this utility model, the probe may be one of a three-hole probe, a five-hole probe, or a seven-hole probe.

[0029] In summary, this invention provides a wind tunnel orientation corrector that achieves flexible adjustment of the probe's height and angle through the cooperation of a lifting mechanism and a locking mechanism. The lifting mechanism precisely controls the probe's lifting height, while the locking mechanism easily adjusts the probe's rotation angle, allowing the probe to quickly adapt to different experimental requirements and improving the flexibility of wind tunnel testing. By optimizing the probe's connection method and the design of the limiting wheel, the disturbance of components such as connecting rods in the airflow is effectively reduced.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] 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.

[0043] Please see Figures 1 to 4 This utility model discloses a wind tunnel direction corrector, aiming to at least solve the problem of the probe 400 being difficult to adjust during use in current related technologies. Specifically, the wind tunnel direction corrector includes at least a mounting bracket 100, a mounting plate 300, a locking mechanism, a probe 400, and a controller connected to the probe 400. The controller can be used to receive and correct the airflow data sensed by the probe 400. The controller is the core for realizing automated and intelligent adjustment.

[0044] The mounting plate 300 is vertically and flexibly connected to the mounting bracket 100, and the locking mechanism is located on the mounting plate 300. Understandably, the probe 400 is locked to the locking mechanism so that the probe 400 can be height-adjusted along with the mounting plate 300, thereby adapting to the height requirements of different detection processes.

[0045] It should be noted that probe 400 may be a three-well probe 400, a five-well probe 400, or a seven-well probe 400, but is not limited to these and may be determined according to actual needs.

[0046] Specifically, the mounting bracket 100 is equipped with a lifting mechanism, which is connected to the mounting plate 300. Therefore, the height of the mounting plate 300 can be adjusted via the lifting mechanism. The lifting mechanism is controllably connected to a controller to facilitate height adjustment of the mounting plate 300. Simultaneously, a base plate 101 can be connected to the mounting bracket 100, which is fixedly connected to the bottom of the mounting bracket 100, for connection to external devices.

[0047] In this embodiment, the lifting mechanism is key to achieving probe height adjustment. A lifting motor drives the lifting screw to rotate, which in turn causes the slider to slide within the mounting frame, thus raising and lowering the mounting plate and probe. The design of the lifting mechanism not only ensures the smoothness of probe lifting but also achieves precise height adjustment through precise motor control.

[0048] Please see Figures 1 to 4 In some embodiments, the lifting mechanism includes a lifting motor 110, a lifting lead screw 120, and a slider 130. The lifting motor 110 is fixedly connected to the top of the mounting frame 100, and the lifting lead screw 120 is rotatably connected within the mounting frame 100, with the lead screw 120 being driveably connected to the lifting motor 110. Therefore, the lifting motor 110 can drive the lifting lead screw 120 to rotate.

[0049] Understandably, the slider 130 is slidably connected within the mounting bracket 100 and is engaged with the lifting screw 120. When the lifting screw 120 rotates, it drives the slider 130 to move along the axis of the lifting screw 120. Therefore, the mounting plate 300 is fixedly connected to the slider 130 and moves synchronously with the slider 130.

[0050] It should be noted that the lifting motor 110 may be a servo motor to improve the accuracy of the slider 130 during the lifting process.

[0051] Please see Figures 1 to 4 In some embodiments, the locking mechanism includes a locking band 210, a limiting wheel 220, and a locking motor 200. The locking motor 200 is fixedly connected to the slide plate 320 and is driven by the locking band 210. The probe 400 can be locked between the locking band 210 and the limiting wheel 220. The locking motor 200 is connected to a controller, which can drive the locking band 210 to rotate, thereby adjusting the angle of the probe 400.

[0052] In this invention, the controller receives operation commands and controls the operation of the lifting motor 110 and the locking motor 200, enabling precise adjustment of the probe height and angle. Simultaneously, the controller can preset the probe adjustment parameters according to experimental requirements, further improving the efficiency and accuracy of wind tunnel testing.

[0053] Furthermore, a drive wheel 201 is connected to the main shaft of the locking motor 200, and the drive wheel 201 is connected to the locking band 210.

[0054] It should be noted that since the locking motor 200 is fixedly connected to the slide plate 320, the position of the locking motor 200 can be adjusted according to the diameter of different probes 400 to improve the applicability of this device.

[0055] To improve the stability of the slide plate 320 during use, a locking bolt 310 can be installed between the slide plate 320 and the mounting plate 300. Specifically, a slot can be provided on the side of the mounting plate 300, and the locking bolt 310 is slidably connected within the slot. The end of the locking bolt 310 is threaded onto the slide plate 320. When the slider 130 reaches the desired position, the locking bolt 310 can be used to lock the slider 130 and the slide plate 320 together.

[0056] Therefore, it is understandable that the probe 400 can be raised and lowered with the mounting plate 300, and the locking band 210 can be used to drive the probe 400 to rotate.

[0057] In this embodiment, the locking mechanism is crucial for achieving probe angle adjustment and locking. The locking band rotates via a locking motor, which in turn rotates the probe. Simultaneously, the teeth on the inner side of the locking band mesh with the toothed structure of the probe connection, ensuring the probe's stability during rotation. The design of the limiting wheel further enhances the probe's support stability and reduces airflow disturbance.

[0058] Please see Figures 1 to 4 In some embodiments, to improve the performance of the device in actual use, an opening is provided at one end of the mounting plate 300, and two sets of limiting wheels 220 are provided. The two sets of limiting wheels 220 are symmetrically arranged at the opening, and the limiting wheels 220 are rotatably connected to the mounting plate 300.

[0059] The probe 400 has a connecting part 410, which is a toothed structure. The inner side of the locking band 210 has strip teeth that can mesh with the toothed structure, and the toothed structure also meshes with two limiting wheels 220. Therefore, by rotating the locking motor 200, the locking band 210 can drive the probe 400 to rotate, thereby achieving angle adjustment of the probe 400 during the measurement process and improving the actual measurement accuracy.

[0060] The two limiting wheels 220 are designed to accommodate probes 400 of different diameters, thereby improving the applicability of the device in actual use.

[0061] Please see Figures 1 to 4 In some embodiments, a limiting ring 420 is provided at the tail of the probe 400, and the hose 430 connected to the controller is sleeved on the limiting ring 420 to improve the stability of the hose 430 during connection.

[0062] In this invention, the flexible hose serves as the connecting component between the probe and the controller, enabling data transmission and reducing stress caused by probe movement through its flexibility. The design of the limiting ring ensures a stable connection between the hose and the probe, improving the reliability of data transmission.

[0063] In summary, this utility model provides a wind tunnel orientation corrector, in which the probe 400 is locked to a locking mechanism, allowing the probe 400 to be height-adjusted along with the mounting plate 300 to adapt to different height requirements during detection processes. Simultaneously, the locking mechanism can be used to lock probes 400 of different diameters, and the angle of the probe 400 can be adjusted via the locking band 210. This enables the probe 400 to be adjusted in both height and circumferential position during actual measurement, effectively improving the current problem of the probe 400 being difficult to adjust during use.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.

For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies both A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
