[0048] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0049] A low-speed wind tunnel atmospheric turbulence simulation device provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0050] Example 1:

[0051] Combine Figures 1 to 11 As shown, the present invention provides a low-speed wind tunnel atmospheric turbulence simulation device, which includes a wind tunnel test mechanism 100, an energy supply mechanism 200 installed in the wind tunnel test mechanism 100, a terrain shaping mechanism 300 installed in the middle of the energy supply mechanism 200, and a terrain simulation component 400 arranged on the terrain shaping mechanism 300 and located in the middle of the inner cavity of the wind tunnel test mechanism 100.

[0055] The terrain simulation assembly 400 includes a deformable base fabric 430 attached to the top surface of the base platform 330, two fixed side fabrics 440 fixedly connected to the sides of the deformable base fabric 430, and a pad 410 disposed on top of the fixed side fabrics 440. The pads 410 are four in number, with each pair of pads 410 forming a group.

[0056] A set of cushions 410 is provided with a limiting rod 4101, and the limiting rod 4101 is used to provide pressure protection for the deformable base fabric 430;

[0057] Two crossbars 420 respectively installed in the two sets of pads 410 and a sleeve roller 4201 movably installed outside the crossbar 420;

[0058] The top of the cushion 410 is provided with an inclined surface adapted to the ridges at both ends of the fixed edge cloth 440, for effectively guiding the airflow and preventing the airflow from being blocked after passing through the wind tunnel;

[0059] The energy supply mechanism 200 includes four bases 210 fixedly mounted in rectangular slots, with two bases 210 forming a group, two slides 220 movably mounted on the inner side of a group of bases 210, an outer clamping plate 2204 fixedly mounted on the outer ends of the slides 220, an inner clamping plate 2205 fixedly mounted on the bottom of the inner ends of the slides 220, a limiting column 230 movably mounted inside the two slides 220, a second spring 240 disposed outside the limiting column 230 and bearing pressure on the inner wall of the slide 220, and a push beam plate 250 inserted into the two slides 220;

[0060] Two first bolts 260 are installed at the inner ends of the two slide seats 220, and the two first bolts 260 are used to fix the push beam plate 250;

[0061] A support plate 2201 is fixedly mounted on the inner ends of the two slides 220, and two studs 2202 are fixedly mounted on the bottom of the support plate 2201. A clamp 2203 is mounted on the outside of the two studs 2202, and the clamp 2203 is mounted on the limit column 230. A traction frame 270 is movably mounted on the inner clamping plate 2205, an end plate 2701 is movably mounted on the other end of the traction frame 270, and a hydraulic component 280 is fixedly mounted on the bottom of the base platform 330, and the end plate 2701 is fixedly mounted on the outer end of the hydraulic sub-rod;

[0062] The two ends of the fixed edge cloth 440 are fixedly mounted on the top of two of the bases 210;

[0063] The outer end of the deformable base fabric 430 is fixedly mounted on the top of the support plate 2201 .

[0064] The device to be tested is placed in advance in the designated test area of ​​the wind tunnel test mechanism 100. At this time, the rectangular cavity of the wind tunnel test mechanism 100 can perform the wind tunnel test of the device to be tested in the optimal state;

[0065] When the anti-interference test of the device under test needs to be conducted in a simulated terrain environment, the hydraulic component 280 is operated until the hydraulic sub-rod in the hydraulic component 280 cooperates with the end plate 2701 to push the two traction frames 270 to extend relative to each other. At this time, the two traction frames 270 will pull the two sets of slides 220 to slide at equal intervals, and the two sets of slides 220 will adjust the tension of the deformable base fabric 430;

[0066] After the two sets of slides 220 relatively tighten the deformable base fabric 430, the two symmetrically distributed push beam plates 250 will laterally squeeze the multiple guide rods 3602 distributed in an inclined state. Finally, the evenly distributed multiple slides 360 will prompt the evenly distributed multiple bottom support rods 340 to lift upward, and the multiple slides 360 will gradually raise the deformable base fabric 430. Finally, the raised part of the deformable base fabric 430 can simulate the structure of the environmental ground, thereby facilitating the anti-terrain structure interference test of the equipment under test.

[0067] Example 2:

[0068] Combine Figures 2 to 5 As shown, based on Example 1, a vertical tube is fixedly installed on the top of the top plate 130, and a propulsion rod 150 is movably installed in the vertical tube. A gasket 1501 is fixedly installed on the propulsion rod 150, and a spring 1502 is arranged outside the propulsion rod 150 and bears pressure on the vertical tube;

[0069] The wind tunnel test mechanism 100 further includes a roof panel 160 disposed directly below the top panel 130 , with one end of the roof panel 160 fixedly mounted to the bottom of the top panel 130 , a fixture 140 fixedly mounted on the outer wall of the side panel 120 , and a pulley 1401 movably mounted within the fixture 140 ;

[0070] Two cables 170 are movably mounted on the propulsion rod 150 , and the cables 170 are adapted to be pressurized in the annular groove of the pulley 1401 .

[0071] Preferably, the top surfaces of the two bases 110 are aligned with the surfaces of the deformable base fabric 430 and the two fixed edge fabrics 440 in the initial state, and the outer inclined surfaces of the four cushions 410 and the top surfaces of the two bases 110 form a smooth curved surface to reduce interference with the airflow passing through the wind tunnel.

[0072] The frame formed by the pulley 1401 and the clamp 140 is used to provide anti-slip protection for the reciprocating extension of the cable 170.

[0073] Example 3:

[0074] Combine Figure 5 、 Figure 8 and Figure 9 As shown, in the above embodiment, the roof plate 160 is composed of a stainless steel inner plate and elastic fabric, and one end of the elastic fabric is fixed to the bottom of the top plate 130, while the stainless steel inner plate is welded to the bottom end of the propulsion rod 150;

[0075] The cable 170 is composed of a rope and two U-shaped clamps, one of which is movably mounted on the propulsion rod 150 and the other is movably mounted on the outer clamping plate 2204;

[0076] The push beam plate 250 has a T-shaped structure, and four evenly distributed insertion holes are opened in the plate at the bottom of the push beam plate 250. The insertion holes are used to provide sufficient and stable bearing pressure for the evenly distributed multiple guide rods 3602.

[0077] Preferably, the length of the roof panel 160 is twice the width of the combined deformable base fabric 430 and the two deformable base fabrics 430. As the propulsion rod 150 pushes the roof panel 160 downward smoothly, the roof panel 160 and the bottom of the top panel 130 form a smooth curved surface. After the airflow enters the wind tunnel, it passes through the deformed deformable base fabric 430 along the smooth curved surface.

[0078] Specifically, after the two sets of slides 220 move closer to the terrain shaping mechanism 300, the stretched and deformed deformable base fabric 430 will not become abnormally loose when under pressure, thereby improving the authenticity of the data measured by the device under test.

[0079] The working principle and use process of the present invention are as follows: When in use, the inner cavity of the wind tunnel test mechanism 100 in the initial state is a rectangular structure, and the cavity of the rectangular structure can be used to test the wind tunnel in the normal state;

[0080] When it is necessary to conduct anti-terrain interference testing in the wind tunnel;

[0081] The hydraulic component 280 is pre-operated until the hydraulic sub-rod in the hydraulic component 280 extends outwards, and the end plate 2701 fixedly installed at the outer end of the hydraulic sub-rod will drop downwards, and the two traction frames 270 movably installed at both ends of the end plate 2701 will pull the two inner clamping plates 2205 and the two slides 220, and the horizontal support plates 2201 arranged at the inner ends of the two slides 220 will tighten the two ends of the deformable base fabric 430. At the same time, the two push beam plates 250 will also shape the terrain synchronously. As the mechanism 300 approaches, the push beam plate 250 applies a lateral squeezing force to the four evenly distributed guide rods 3602. Finally, the four obliquely distributed guide rods 3602 cooperate with the four cover plates 3601 and the four slides 360 to move toward the center of the base platform 330. Guided by the inclined chutes inside the slides 360, the slide rods 3402 are lifted upward along the inclined chutes. Finally, the slide rods 3402 and the bottom support rods 340 are lifted upward along the inner cavity of the sleeve 3301.

[0082] As the evenly distributed multiple bottom support rods 340 gradually extend toward the top surface of the base platform 330, the evenly distributed multiple bottom support rods 340 will be arranged in a wave-shaped structure. At this time, the top of the deformable base fabric 430 will be effectively shaped by the evenly distributed multiple bottom support rods 340 until the raised portion of the deformable base fabric 430 simulates the terrain structure of the external environment.

[0083] At the same time, after the two outer plates 2204 move laterally synchronously with the slide 220, the cables 170 movably installed on the two outer plates 2204 will apply downward pressure to the propulsion rod 150. As the pressure on the propulsion rod 150 continues to decrease, the crests on the top surface of the deformable base fabric 430 gradually form. The roof plate 160 pressurized by the bottom end of the propulsion rod 150 will cooperate with the forming of the crests of the deformable base fabric 430 to reduce the area through which the airflow passes, thereby simulating the flow rate and turbulence of the airflow passing through hilly terrain.

[0084] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
