Description

Technical Field

[0001] The present invention relates to the technical field of hypergravity environment simulation test, in particular to a wind direction regulating device and a hypergravity environment simulation test box. Background Art

[0002] An environmental simulation test chamber is a device used to simulate various natural or specific environmental conditions. It is mainly used to evaluate the performance and reliability of products, materials or components under different environmental conditions (such as temperature, humidity, air pressure, flow field, light, salt spray, etc.). When the environmental simulation test chamber needs to simulate the temperature, humidity, flow field, etc. inside the chamber, the parameters are often controlled and adjusted by supplying air into the test chamber. Therefore, the wind direction adjustment device is one of the important components of an environmental simulation test chamber with an air supply function. Unlike wind direction adjustment devices working in a normal gravity environment, in a hypergravity environment, the air guide structure in the wind direction adjustment device will not only be affected by aerodynamic forces, but also by dozens or even hundreds of times the hypergravity.

DETAILED DESCRIPTION

[0050] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] As described in the background technology, unlike wind direction adjustment devices working in normal gravity environments, in hypergravity environments, the wind guide structure in the wind direction adjustment device will not only be affected by aerodynamic forces, but also by dozens or even hundreds of times the hypergravity. After the wind guide structure rotates a certain angle, it has a large spontaneous rotation tendency, which seriously affects the stability and reliability of wind direction adjustment.

[0052] To solve the above problems, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 , mention 7, Figure 8 、 Figure 9 and Figure 10 On the one hand, the present invention provides a wind direction adjustment device for use in a hypergravity environment simulation test, comprising an installation bin 110, an air guide structure 120, and a first damping structure 130. A first air inlet is formed at the top of the installation bin 110, and a first air outlet is formed at the bottom and one side, respectively. Air flow can flow into the installation bin 110 from the first air inlet, and can flow out of the installation bin 110 through the first air outlet. The air guide structure 120 is rotatably arranged in the installation bin 110 around its own axis to change the direction of wind flow. One of the first damping structures 130 is used to connect one end of the installation bin 110 with one end of the air guide structure 120, and the other first damping structure 130 is used to connect the other end of the installation bin 110 with the other end of the air guide structure 120. The two first damping structures 130 provide greater rotational resistance, effectively preventing the air guide structure 120 from spontaneously rotating, thereby improving the stability and reliability of wind direction adjustment.

[0053] Specifically, in this example, each first damping structure 130 includes an internal spline 131 and an external spline 132. The internal spline 131 is fixedly mounted to one end of the mounting compartment 110 via a mounting block. The external spline 132 is fixedly mounted to one end of the wind guide structure 120 and meshes with the internal spline 131. Leveraging the high torque transmission capability of the spline coupling, the wind guide structure 120 is effectively prevented from spontaneously rotating in a hypergravity environment, improving the stability and reliability of wind direction adjustment.

[0054] Preferably, the air guide structure 120 and the external spline 132 are manufactured using an integrated molding process, thereby improving production efficiency.

[0055] Specifically, in the example, Figure 1 and Figure 2As shown, a support plate 111 is formed in the middle of the installation bin 110 to separate the installation bin 110 into a first air guide cavity and a second air guide cavity. The air guide structure 120 includes a first air guide section 121, a second air guide section 122 and a first rotating shaft 123. The first air guide section 121 can be rotatably arranged in the first air guide cavity around its own axis. The second air guide section 122 can be rotatably arranged in the second air guide cavity around its own axis. The first rotating shaft 123 is rotatably mounted on the support plate 111, with one end fixedly connected to the first air guide section 121 and the other end fixedly connected to the second air guide section 122. The first rotating shaft 123 is an optical axis. The air guide structure 120 is designed in sections along the axial direction, and with the support of the support plate 111, flexible deformation of the rotating shaft in a hypergravity environment is avoided.

[0056] Specifically, in the example, Figure 2 As shown, the first air guide section 121 includes a second rotating shaft 1211, a first wind shield 1212, a second wind shield 1213, a sealing plate 1214, a partition 1215 and two reinforcing plates 1216. One end of the second rotating shaft 1211 is connected to one end of the installation compartment 110 through the first damping structure 130. The first wind shield 1212 is arranged on one side of the second rotating shaft 1211. The second wind shield 1213 is arranged on the other side of the second rotating shaft 1211, and a second air outlet is formed between the bottom side and the bottom side of the first wind shield 1212. One side of the sealing plate 1214 is fixedly connected to the top side of the second wind shield 1213, and the other side is fixedly connected to the top side of the first wind shield 1212 to form a second air inlet. The top side of the partition 1215 is fixedly connected to the side wall of the second rotating shaft 1211. The air flow flows into the first air guide section 121 from the second air inlet, passes through the opposite sides of the partition 1215, and then flows out of the first air guide section 121 from the second air outlet. The direction of the second air outlet is the air outlet direction. The cross section of the sealing plate 1214 is an arc-shaped structure. During the rotation of the first air guide section 121, the sealing plate 1214 seals the gas to ensure that the air flow flows in the set direction. The second rotating shaft 1211 is arranged at the center of the first air guide section 121 to reduce the rotational torque generated by the hypergravity environment on the first air guide section 121. One of the reinforcing plates 1216 is installed at one end of the second rotating shaft 1211, and the other reinforcing plate 1216 is installed at the other end of the second rotating shaft 1211. Each reinforcing plate 1216 is fixedly connected to the first wind shield 1212, the second wind shield 1213, the sealing plate 1214, and the partition 1215 respectively. The two reinforcing plates 1216 can effectively improve the strength of the structure and prevent the aerodynamic force and super gravity from causing deformation of the first air guide section 121. The structure of the second air guide section 122 is the same as that of the first air guide section 121. Figure 5 、 Figure 6 and Figure 7As shown, the first air guide section 121 / the second air guide section 122 can achieve wind direction adjustment of 0°-90°, and after rotating 0-90°, the flow channel structure of the first air guide section 121 / the second air guide section 122 does not change much in the resistance characteristics of the air flow, and the equivalent flow area of the air outlet does not change much either, which is beneficial to reducing the impact of wind direction adjustment on wind speed.

[0057] Specifically, in the example, Figure 1 and Figure 3 As shown, the wind direction adjustment device also includes a second damping structure 140, mounted on the support plate 111 and the first rotating shaft 123, to limit spontaneous rotation of the first rotating shaft 123. The second damping structure 140 comprises a sleeve 141, a plurality of first magnets 142, a plurality of second magnets 143, a plurality of third magnets 144, and a plurality of fourth magnets 145. The sleeve 141 is mounted on the center portion of the support plate 111 and is positioned around the first rotating shaft 123. The plurality of first magnets 142 are evenly fixed to the inner wall of the sleeve 141 along its circumference. The plurality of second magnets 143 are evenly fixed to the inner wall of the sleeve 141 along its circumference. The polarity of each second magnet 143 is opposite to that of each first magnet 142. The plurality of second magnets 143 and the plurality of first magnets 142 are alternately arranged along the circumference of the sleeve 141 to form an outer magnetic ring. Multiple third magnets 144 are evenly fixed to the outer wall of the first rotating shaft 123 along the circumference of the first rotating shaft 123. Multiple fourth magnets 145 are evenly fixed to the outer wall of the first rotating shaft 123 along the circumference of the first rotating shaft 123. The polarity of each third magnet 144 is opposite to the polarity of each fourth magnet 145. The multiple third magnets 144 and the multiple fourth magnets 145 are alternately arranged along the circumference of the sleeve 141 to form an inner magnetic ring. The polarity of each first magnet 142 is opposite to that of each third magnet 144. The polarity of each second magnet 143 is opposite to that of each fourth magnet 145. When the first rotating shaft 123 rotates, it encounters greater resistance, further preventing spontaneous rotation of the first rotating shaft 123, thereby further ensuring the stability and reliability of wind direction adjustment. By combining non-contact resistance and contact resistance, the failure of a single resistance does not affect the final anti-spontaneous rotation effect, greatly improving the stability and reliability of wind direction adjustment.

[0058] In some practical applications, such as Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the wind direction adjustment device also includes an air duct 150. A third air inlet is formed at the top of air duct 150, and a third air outlet is formed at the bottom and on one side of the bottom. An installation compartment 110 is mounted at the bottom of the interior. Installation compartment 110, air guide structure 120, and first damping structure 130 are removably mounted as a unit to the bottom of air duct 150, facilitating assembly and disassembly. Air flows into air duct 150 from the third air inlet and exits duct 150 through the third air outlet.

[0059] In other practical applications, such as Figure 8 、 Figure 9 and Figure 10 As shown, the wind direction adjustment device also includes an air duct 150 and two third damping structures 160. A third air inlet is formed at the top of the air duct 150, and a third air outlet is formed at the bottom and the bottom of one side respectively, and an installation compartment 110 is installed at the bottom inside. The two third damping structures 160 are respectively installed in the installation compartment 110. One of the third damping structures 160 is connected to the second rotating shaft 1211 of the first air guide section 121, and is used to limit the spontaneous rotation of the first air guide section 121. The other third damping structure 160 is connected to the second rotating shaft 1211 of the second air guide section 122, and is used to limit the spontaneous rotation of the second air guide section 122. Each third damping structure 160 includes a horizontal threaded rod 161, a movable seat 162, a vertical threaded rod 163, a spring 164, two first locking nuts 165 and two second locking nuts 166. The horizontal threaded rod 161 is detachably mounted on the top of the air duct 150 through a mounting block. The movable seat 162 can be installed on the horizontal threaded rod 161 so as to be movable along the axial direction of the horizontal threaded rod 161. The top end of the vertical threaded rod 163 passes through the movable seat 162 and can move up and down. The axis of the spring 164 is arranged vertically, the top end is detachably mounted on the bottom end of the vertical threaded rod 163, and the bottom end is detachably mounted on the second rotating shaft 1211. The two first locking nuts 165 are respectively screwed onto the horizontal threaded rod 161 and are located on opposite sides of the movable seat 162, which can limit the axial movement of the movable seat 162 along the horizontal threaded rod 161 or release the restriction on the movable seat 162. The two second locking nuts 166 are respectively screwed onto the vertical threaded rod 163 and are located on the upper and lower sides of the movable seat 162, which can limit the up and down movement of the vertical threaded rod 163 or release the restriction on the vertical threaded rod 163. When air guide structure 120 rotates a certain angle to adjust the wind direction, the horizontal position of movable seat 162 and the vertical position of vertical threaded rod 163 are adjusted to place spring 164 in a natural position. When second rotating shaft 1211 rotates spontaneously, spring 164 extends to generate a traction force on second rotating shaft 1211 to prevent second rotating shaft 1211 from rotating spontaneously.

[0060] The present invention also provides a hypergravity environment simulation test chamber, comprising a chamber and a wind direction adjustment device installed within the chamber. This device achieves reliable wind direction adjustment within the hypergravity environment simulation test chamber. By employing a modular design, central placement of the second rotating shaft 1211, segmented support, and spline positioning, the effects of the hypergravity environment on the wind direction adjustment device are significantly reduced, thereby improving the reliability of wind direction adjustment. The overall structure is simple, safe, and reliable, achieving excellent results.
