[0033] Among them, the fan and the pressure detection component used in the kinetic experiment are both prior arts and will not be elaborated here; at the same time, the present invention also includes a power supply, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here.

[0034] The working principle of the technical solution provided by the present invention: The fan 2 under the platform frame 1 serves as a power source, conveys air flow to the inside of the air outlet pipe 5 through the air duct 3, and blows it out through the air outlet of the air outlet pipe 5 to the air outlet pipe 7. The experimental platform integrates a flow sensor and a solenoid valve to monitor and adjust the wind speed and air volume in real time, adapt to different test conditions. The slider 63 is embedded in the T-shaped slot of the air outlet pipe 5, and the guiding vertical frame 61 slides inside the positioning block 62. After adjusting to the height of fixing the test instrument, by screwing the fastening bolt 64 to abut against the anti-slip layer of the guiding groove 65, rapid positioning of the test piece is achieved. The rotating buckle 68 is rotated and opened inside the rotating frame 69, and the buckle 68 is positioned by cooperating with the baffle 610. The experimental instrument is placed on the buckle 68, or the storage frame 67 is pulled inside the limiting frame 66, and the opened space is used for positioning the test instrument with a hook structure to prevent displacement during the test.

[0035] In some wind force experiment requirements that need to extend the air duct, the extension pipe 82 located inside the air outlet pipe 7 is pulled out through the positioning end 81. The sliding frame 83 can slide outside the pulley group 84 to reduce friction and is more convenient for pulling out the extension pipe 82 to open, realizing free adjustment of the air duct length. After the extension pipe 82 is stretched and moved, the card shaft 810 structure inside the push rod 89 is engaged with the card slot 88 of the adjustment frame 87 to fix the extended length and prevent the extension pipe 82 from being completely blown out during the wind force impact process. And when filtration is required, the filter net 86 is installed into the inner part of the round groove 812 through the mounting frame 85, and the filter net 86 embedded in the mounting frame 85 intercepts impurities in the air flow to avoid polluting the test environment or damaging the test piece.

[0036] When placing the experimental apparatus required for the wind power experiment, rotate the support nut 96 to drive the placement plate 94 to slide up and down along the threaded shaft 93. The thickening layer 97 enhances the load-bearing stability and adapts to the storage of test apparatuses of different sizes. By presetting the wind speed and air volume of the fan 2 through the control unit 4, it adapts to the experimental requirements. Place the test piece in the storage frame 67, slide the positioning block 62 to adjust the position and then tighten the fastening bolt 64; rotate the buckle 68 to fasten the storage frame 67 to complete the quick fixation.

[0037] Turn on the fan 2, and the control unit 4 monitors the wind speed and air volume in real time to ensure stable output; the air flow acts on the test piece through the air outlet pipe 5 and the extension pipe 82. The pressure detection component is used to collect the stress and displacement data of the test piece under the air flow load and feedback it to the controller for analysis. If it is necessary to change the air flow parameters, adjust the power of the fan 2 or the opening degree of the solenoid valve through the control unit 4; if it is necessary to replace the test piece, loosen the buckle 68 and loosen the fastening bolt 64, quickly replace it and then relock it. After the experiment is over, turn off the fan 2, push the extension pipe 82 into the interior of the air outlet pipe 7, rotate the support nut 96 to lower the placement plate 94, and store the experimental apparatus; clean the impurities on the filter screen 86.
