[0023] The present invention relates to an adjustable multi-purpose wind tunnel simulation device, the structural design and functional realization of which are centered on improving the flexibility, adaptability and ease of operation of the experimental equipment. Figure 1 To Attachment Figure 4 The specific implementation of the present invention is described in detail with reference to the component numbers marked in the accompanying drawings. Figure 1 As shown, the wind tunnel simulation device mainly includes an adjustment structure 1, a wind tunnel body 2 and an auxiliary module 3, wherein the adjustment structure 1 is used to support and adjust the height and angle of the wind tunnel body 2. The wind tunnel body 2 as the core experimental area is responsible for the generation and control of airflow, and the auxiliary module 3 provides a variety of experimental scene support through a detachable design.

[0024] First, the composition and operation principle of the adjustment structure 1 are described. The adjustment structure 1 includes a base 11, a lifting mechanism 12, a rotating table 13, a driving motor 14, a screw 15, a slider 16, a connecting rod 17 and a support seat 18. The base 11 is a rectangular frame structure, and anti-slip pads are provided at its four corners to enhance the stability of the device during the experiment. The lifting mechanism 12 is fixedly installed at the center of the base 11, and its top is connected to the rotating table 13, thereby providing a basis for height adjustment for the wind tunnel body 2. The design of the rotating table 13 allows the wind tunnel body 2 to be adjusted in the horizontal direction to meet different experimental requirements. The driving motor 14 is fixedly installed at the bottom center of the rotating table 13, and its output shaft is connected to one end of the screw 15, and the other end of the screw 15 passes through the rotating table 13 and extends to the top. The slider 16 is movably mounted on the screw 15, and its range of movement is determined by the length of the screw 15. One end of the connecting rod 17 is hinged to the slider 16, and the other end is hinged to the bottom of the support seat 18, so as to convert the linear motion of the slider 16 into the lifting motion of the support seat 18. When the driving motor 14 is started, the screw rod 15 rotates accordingly, and the slider 16 moves along the axial direction of the screw rod 15. Due to the hinge effect of the connecting rod 17, the movement of the slider 16 will drive the support seat 18 to adjust its height under the support of the rotating table 13. This design not only realizes the flexible adjustment of the height of the wind tunnel body 2, but also ensures the stability and accuracy of the adjustment process.

[0025] Next, the internal structure and working principle of the wind tunnel body 2 are described in detail. The wind tunnel body 2 includes a shell 21, a deflector group 22, a fan assembly 23, a sensor array 24 and a pair of control knobs 25. The shell 21 is a cylindrical cavity structure, and an air inlet and an air outlet are respectively opened at its left and right ends for the input and output of airflow. The deflector group 22 is movably arranged inside the shell 21 near the air inlet, and its angle can be adjusted by one of the control knobs 25 to change the direction and distribution of the airflow. The fan assembly 23 is fixedly installed in the middle of the inner wall of the shell 21 to generate a stable airflow. The sensor array 24 is evenly distributed on the inner wall of the shell 21 near the air outlet, and is used to monitor the speed, pressure and other parameters of the airflow in real time, and feed the data back to the external control system. The control knobs 25 are symmetrically arranged on the outer wall of the shell 21 near the bottom corners, one of which is used to adjust the angle of the deflector group 22, and the other is connected to the electromagnetic lock 36 and the sensor array 24 to control the power supply state of the electromagnetic lock 36. The housing 21 is fixedly connected to the adjustment structure 1 via the support base 18, thereby achieving overall height and angle adjustment.

[0026] The design of the auxiliary module 3 further enhances the versatility and scope of application of the wind tunnel simulation device. The auxiliary module 3 includes a bracket 31, a pair of slots 32, a pair of filters 33, two pairs of elastic buckles 34, a pair of limit blocks 35, an electromagnetic lock 36 and a test model. The bracket 31 is a U-shaped structure, and its two ends are respectively inserted into the slots 32 to achieve a detachable connection with the inner wall of the shell 21. The filter 33 is movably arranged on both sides of the bracket 31 to filter impurities in the airflow or simulate specific experimental conditions. The two pairs of elastic buckles 34 are symmetrically fixed to the inner wall of the bracket 31, and one end thereof is attached to the outside of the filter 33. When the electromagnetic lock 36 is powered off, the force of the elastic buckle 34 will pop the filter 33 outward to the outside of the shell 21, which is convenient for users to quickly replace or clean. The limit blocks 35 are symmetrically arranged on the opposite side walls of the bracket 31, and cooperate with the electromagnetic lock 36 to fix the position of the filter 33. The electromagnetic lock 36 is fixedly installed at the bottom center of the bracket 31. When it is powered on, it adsorbs the limit block 35 to lock the filter 33; when it is powered off, the limit block 35 is released, so that the filter 33 pops out under the action of the elastic buckle 34. The test model is movably placed in the bracket 31 and keeps a certain distance from the filter 33 to avoid interfering with the normal flow of air. By replacing different test models and filter 33 combinations, the wind tunnel simulation device can adapt to a variety of experimental scenarios, such as aerodynamic testing, particulate matter filtration performance evaluation, etc.

[0027] In practical applications, the operation process of the wind tunnel simulation device is as follows. First, adjust the height and angle of the wind tunnel body 2 according to the experimental requirements. By starting the drive motor 14, the screw 15 rotates to drive the slider 16 to move axially, and then the support seat 18 is lifted and lowered by the connecting rod 17. At the same time, the rotating table 13 can manually or automatically adjust the horizontal angle of the wind tunnel body 2 to meet the airflow direction requirements under different experimental conditions. Then adjust the angle of the guide plate group 22 by the control knob 25 to optimize the distribution and speed of the airflow. Then start the fan assembly 23, the airflow enters the housing 21 from the air inlet, and flows to the test area after being guided by the guide plate group 22. The sensor array 24 monitors the airflow parameters in real time and feeds back the data to the external control system for the experimenter to analyze and record. If the filter 33 or the test model needs to be replaced, the power supply of the electromagnetic lock 36 is disconnected by another control knob 25, the limit block 35 is released immediately, and the elastic buckle 34 pops the filter 33 out of the housing 21, which is convenient for the user to quickly complete the replacement operation. After the replacement is completed, the electromagnetic lock 36 is powered on again, and the limit block 35 locks the filter screen 33 again to ensure the stability of the auxiliary module 3 during the experiment.

[0028] In addition, the wind tunnel simulation device also has high scalability and compatibility. For example, by replacing the brackets 31 and filters 33 of different specifications, experimental conditions of different sizes and materials can be simulated. At the same time, the data acquisition capability of the sensor array 24 can also be upgraded according to the experimental requirements to support higher-precision measurement tasks. In addition, the design of the adjustment structure 1 enables the wind tunnel body 2 to adapt to the requirements of a variety of experimental sites, and can operate stably whether in a laboratory environment or outdoor field testing.

[0029] In summary, the present invention realizes the multifunctional integration and efficient operation of the wind tunnel simulation device through the height and angle adjustment function of the adjustment structure 1, the airflow control and monitoring capability of the wind tunnel body 2, and the diversified experimental support of the auxiliary module 3. Its innovative design not only improves the flexibility and application scope of the experimental equipment, but also significantly optimizes the convenience of operation, thereby improving the experimental efficiency and the accuracy of the results.
