[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1

[0042] See also Figures 1 to 7 A wind knife test platform provided in this embodiment includes: a frame 2; an adjustment mechanism, including two groups of first adjustment components 3, the two groups of first adjustment components 3 are arranged on the frame 2 at intervals along the first horizontal direction, and the first adjustment components 3 are slidably connected to the frame 2; a wind knife 1 is suitable for being installed between the two groups of first adjustment components 3, and the two ends of the wind knife 1 are respectively connected to the adjustment ends of the two groups of first adjustment components 3; a verification mechanism, which is slidably connected to the frame 2 along the first horizontal direction, and is driven by a driving component to slide back and forth on the frame 2; the detection end of the verification mechanism faces the air outlet of the wind knife 1, and is suitable for detecting the wind force information of the air outlet of the wind knife 1.

[0043] It should be noted that the detection end of the verification mechanism is aligned with the air outlet of the wind knife 1; the wind knife 1 is installed along the first horizontal direction.

[0044] In this embodiment, when the wind knife 1 needs to be tested, the wind knife 1 is connected between two first adjustment components 3. The two groups of first adjustment components 3 can slide on the frame 2 according to the length of the wind knife 1 to adjust the distance between the two for adaptation, so as to adapt to wind knifes 1 of different lengths and improve the scope of application. After the wind knife 1 is installed, gas is introduced into the wind knife 1, and then the detection end of the verification mechanism is aligned with the air outlet of the wind knife 1. At the same time, the verification mechanism is driven by the driving component to reciprocate along the first horizontal direction on the frame 2, so that the verification mechanism detects the wind force information of the wind at multiple positions of the air outlet of the wind knife 1, such as wind speed and air pressure, and then the uniformity of the air outlet of the wind knife 1 can be verified.

[0045] Example 2

[0046] As a further improvement to Example 1, Figure 2 and Figure 3 As shown, the first adjustment component 3 includes a guide fixing seat 301, a guide rod 302 and a connecting seat 303; the guide fixing seat 301 is slidably connected to the frame 2; the guide rod 302 is arranged on the guide fixing seat 301 along the vertical direction, and the guide rod 302 is provided with a first scale 7 along the vertical direction; the connecting seat 303 can be slidably mounted on the guide fixing seat 301, and the connecting seat 303 is suitable for connecting the wind knife 1.

[0047] In this embodiment, after adjusting the spacing on the frame 2 according to the length of the wind knife 1 through two guide fixing seats 301, the two ends of the wind knife 1 are respectively connected to the connecting seats 303 of the two groups of first adjustment components 3. At the same time, the connecting seats 303 can be adjusted to slide up and down on the guide rod 302 according to the first scale 7. The first scale 7 is used to ensure that the connecting seats 303 on the two groups of first adjustment components 3 are consistent in the height direction, so that the installed wind knife 1 remains horizontal to ensure the accuracy during calibration. The first scale 7 is used to improve the accuracy of horizontal calibration, reduce the time of horizontal adjustment, and improve the adjustment efficiency. If there is an offset in the horizontality of the wind knife 1 during the measurement process, it can be discovered in time for adjustment.

[0048] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 3 As shown, the first adjustment component 3 also includes an adjustment member, which includes an adjustment screw 304 and an adjustment block 305. The adjustment block 305 is arranged at the top of the guide rod 302; the adjustment screw 304 passes through the adjustment block 305 in the vertical direction, and the bottom end of the adjustment screw 304 is connected to the connecting seat 303; the adjustment screw 304 is threadedly connected to the adjustment block 305.

[0049] In this embodiment, when it is necessary to adjust the vertical position of the connecting seat 303, by rotating the adjusting screw 304, due to the threaded cooperation between the adjusting screw 304 and the adjusting block 305, the adjusting screw 304 can move in the vertical direction relative to the adjusting block 305, thereby driving the connecting seat 303 to move in the vertical direction on the guide rod 302, thereby performing horizontal calibration on the wind knife 1. The threaded cooperation between the adjusting screw 304 and the adjusting block 305 can improve the adjustment accuracy.

[0050] Specifically, a through hole is opened on the adjustment block 305 along the vertical direction, the adjustment screw 304 is inserted into the through hole, an adjustment nut is coaxially provided on the adjustment block 305 corresponding to the through hole, and the adjustment screw 304 is threadedly connected with the adjustment nut.

[0051] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 3 As shown, the connecting seat 303 includes a first straight line segment and a second straight line segment, and the first straight line segment and the second straight line segment are connected in an L shape in sequence; the first straight line segment is sleeved on the guide rod 302 through a first through hole, and a first opening connected to the first through hole is provided at one end of the first straight line segment away from the second straight line segment along the axial direction of the first through hole; a first tightening handle 306 is provided on the outer side of the first straight line segment corresponding to the first opening, which is suitable for adjusting the opening size of the first opening through the first tightening handle 306 to clamp or loosen the guide rod 302; the second straight line segment is provided with a second through hole along the first horizontal direction, and a rotating block 321 is rotatably connected in the second through hole, and the rotating block 321 is suitable for connecting the wind knife 1; a second opening connected to the second through hole is provided at one end of the second straight line segment away from the first straight line segment along the axial direction of the second through hole; a second tightening handle 307 is provided on the outer side of the second straight line segment corresponding to the second opening, which is suitable for adjusting the opening size of the second opening through the second tightening handle 307 to clamp or loosen the rotating block 321.

[0052] It should be noted that the first opening penetrates the side wall of the first straight line segment along the vertical direction and the length direction of the first straight line segment; the second opening penetrates the side wall of the second straight line segment along the first horizontal direction and the length direction of the second straight line segment.

[0053] In this embodiment, when it is necessary to adjust the connection seat 303 to move on the guide rod 302, the first opening is adjusted to be larger through the first tightening handle 306, so that the aperture of the first through hole is enlarged to loosen the guide rod 302, so that the first straight line segment can be adjusted to slide on the guide rod 302. Conversely, after adjusting the position of the connection seat 303 on the guide rod 302, the first opening is adjusted to be smaller through the first tightening handle 306, so that the aperture of the first through hole is smaller to clamp the guide rod 302, so that the first straight line segment can be fixed on the guide rod 302, thereby avoiding displacement due to external force during the measurement process and improving stability. After the knife 1 is connected to the rotating block 321, when the rotation angle of the wind knife 1 needs to be adjusted, the second opening is adjusted to be larger through the second tightening handle 307, so that the aperture of the second through hole is enlarged to loosen the rotating block 321, so that the rotating block 321 can be adjusted to rotate in the second through hole, thereby changing the rotation angle of the wind knife 1. Conversely, after the rotation angle of the wind knife 1 is adjusted, the second opening is adjusted to be smaller through the second tightening handle 307, so that the aperture of the second through hole is smaller to clamp the rotating block 321, so that the rotation angle of the wind knife 1 can be fixed, avoiding displacement due to external force during the measurement process, and improving stability. Adjustment is carried out by cooperating with the first tightening handle 306 and the second tightening handle 307, which is convenient for improving the convenience of adjustment and the efficiency of adjustment, and the rotation angle of the wind knife 1 can be adjusted so as to calibrate the wind knife 1 at different angles.

[0054] Specifically, Figure 2 and Figure 3 As shown, a guide base 319 is provided on the top of the guide fixing seat 301 along the vertical direction, and the guide rod 302 is inserted on the guide base 319 along the vertical direction, so as to facilitate the installation and removal of the guide rod 302.

[0055] Specifically, the first tightening handle 306 includes a first handle portion and a first screw portion, the first screw portion sequentially passes through the two side walls of the first opening and is threadedly connected to the two side walls of the first opening, and the first screw portion can be rotated by the first handle portion to adjust the distance between the two side walls of the first opening, thereby adjusting the opening size of the first opening; the second tightening handle 307 includes a second handle portion and a second screw portion, the second screw portion sequentially passes through the two side walls of the second opening and is threadedly connected to the two side walls of the second opening, and the second screw portion can be rotated by the second handle portion to adjust the distance between the two side walls of the second opening, thereby adjusting the opening size of the second opening.

[0056] Specifically, Figure 2 and Figure 3 As shown, one end of the rotating block 321 is rotatably connected to the second through hole, and the other end is provided with a mounting port for connecting the wind knife 1; the two mounting ports are arranged opposite to each other along the first horizontal direction; a threaded hole is penetrated through the side wall of the rotating block 321 corresponding to the mounting port, which is suitable for threading the mounting screw through the threaded hole to fix the wind knife 1.

[0057] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 3 As shown, the first adjustment component 3 is slidably connected to the frame 2 via a horizontal adjustment component, and is suitable for adjusting the first adjustment component 3 to move along a second horizontal direction through the horizontal adjustment component; the second horizontal direction is perpendicular to the first horizontal direction.

[0058] In this embodiment, when the wind knife 1 is installed between two groups of first adjustment components 3, if the length direction of the wind knife 1 is not parallel to the first horizontal direction, in order to avoid the deviation of the distance between the verification mechanism and the air outlet of the wind knife 1 when sliding along the first horizontal direction to affect the verification accuracy, the first adjustment component 3 can be adjusted to move along the second horizontal direction through the horizontal adjustment component, so that the length direction of the wind knife 1 is parallel to the first horizontal direction, thereby improving the adjustment ability and ensuring the accuracy of the verification of the uniformity of the air outlet of the wind knife 1.

[0059] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 3 As shown, the horizontal adjustment component includes a horizontal slider 308 and a guide locking block 309, the guide locking block 309 is slidably connected to the frame 2, and the first adjustment component 3 is arranged on the top of the horizontal slider 308; the top of the guide locking block 309 is provided with a first guide rail 310 along the second horizontal direction, and the horizontal slider 308 is slidably connected to the first guide rail 310.

[0060] In this embodiment, the first adjustment component 3 is arranged on the horizontal slider 308, and then the horizontal slider 308 can be adjusted to slide along the first guide rail 310 on the guide lock block 309, so that the length direction of the wind knife 1 is parallel to the first horizontal direction.

[0061] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 3 As shown, a horizontal rack 311 is provided on the top of the first guide rail 310 along the second horizontal direction, an adjustment slot 312 is provided on the horizontal slider 308 corresponding to the horizontal rack 311, and an adjustment rod is rotatably connected to the horizontal slider 308 along the first horizontal direction; one end of the adjustment rod extends into the horizontal slider 308 and meshes with the horizontal rack 311 through a gear, and the other end extends out of the horizontal slider 308 and is connected to an adjustment handle 313.

[0062] In this embodiment, when it is necessary to adjust the horizontal slider 308 to move on the first guide rail 310, the adjustment handle 313 is used to rotate the adjustment rod, and the adjustment rod engages with the horizontal rack 311 through the gear, thereby driving the horizontal slider 308 to move on the first guide rail 310, and then adjusting the position of the first adjustment component 3 along the second horizontal direction, thereby adjusting the length direction of the wind knife 1 to be parallel to the first horizontal direction.

[0063] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 3 As shown, a fastening screw 314 is threadedly connected to the side wall of the horizontal slider 308 corresponding to the first guide rail 310 , and is suitable for abutting the first guide rail 310 through the fastening screw 314 to fasten the horizontal slider 308 .

[0064] It should be noted that the fastening screw 314 is disposed in the horizontal sliding block 308 corresponding to the first guide rail 310 .

[0065] In this embodiment, after the position of the horizontal slider 308 is adjusted, the fastening screw 314 can be tightened to make it abut against the first guide rail 310 to prevent the horizontal slider 308 from being offset by external force during the measurement process and affecting the accuracy of the calibration of the wind knife 1. Conversely, when the horizontal slider 308 needs to be adjusted, the fastening screw 314 is rotated in the opposite direction to move it outward to keep it away from the first guide rail 310 to avoid affecting the movement of the horizontal slider 308.

[0066] Based on the above implementation, in a preferred implementation, Figure 3 As shown, the side wall of the horizontal slider 308 is provided with a first limiting portion 315, and the side wall of the guide locking block 309 is provided with a second limiting portion 316 corresponding to the first limiting portion 315, and the projection of the first limiting portion 315 along the second horizontal direction overlaps with the second limiting portion 316.

[0067] In this embodiment, the first limit portion 315 and the second limit portion 316 are limited by abutting against each other in the second horizontal direction, so that when the first limit portion 315 and the second limit portion 316 on the two groups of horizontal adjustment components are abutted against each other, the two horizontal sliders 308 are in the same position along the second horizontal direction, and the two horizontal sliders 308 are arranged in the first horizontal direction, that is, the two groups of first adjustment components 3 are in the first horizontal direction, so that when the wind knife 1 is installed at this position, the length direction of the wind knife 1 is parallel to the first horizontal direction without being affected by external forces.

[0068] Based on the above implementation, in a preferred implementation, Figure 2 and Figure 6As shown, a third guide rail 317 is provided on the frame 2 along the first horizontal direction, and the guide locking block 309 is slidably connected to the third guide rail 317 through a guide rail slider 320. A locking assembly 318 is provided on the guide rail slider 320, and the locking assembly 318 is suitable for locking the guide rail slider 320 on the third guide rail 317.

[0069] In this embodiment, the guide rail slider 320 cooperates with the third guide rail 317 to facilitate the adjustment of the position of the first adjustment component 3 to adapt to wind knives 1 of different sizes. After the position is adjusted, the guide rail slider 320 is fixed to the third guide rail 317 by the locking component 318 to avoid displacement when subjected to external force to affect the accuracy of the calibration. When adjustment is required, the locking component 318 can be released.

[0070] Specifically, the locking assembly 318 includes a third tightening handle, which includes a third handle portion and a third screw portion. The third screw portion and the third guide rail 317 are correspondingly arranged on the guide rail slider 320, and the third screw portion is threadedly connected to the guide rail slider 320. When locking is required, the third handle portion is used to rotate the third screw portion to abut against the third guide rail 317 for locking. Conversely, the third screw portion is rotated in the opposite direction to move away from the third guide rail 317 for easy adjustment.

[0071] Based on the above implementation, in a preferred implementation, Figure 4 and Figure 5 As shown, the verification mechanism includes a measuring probe 4, a second adjusting component 5 and a third adjusting component 6.

If the wind knife 1 is in the horizontal direction If the wind knife 1 is offset from the third guide rail 317, the horizontal sliders 308 at both ends of the wind knife 1 are moved on the first guide rail 310 to adjust the wind knife 1 to be parallel to the third guide rail 317, then the air pressure valve 14 is adjusted to a position corresponding to the air inlet on the wind knife 1, and the air pipe 17 is connected to the air inlet, and the third adjustment component 6 and the second adjustment component 5 are controlled to cooperate to adjust the measuring probe 4 to a preset distance from the air outlet of the wind knife 1, and introduce airflow to the wind knife 1.
