[0042] Embodiment 1

[0043] The existing stage wind effect adjustment device has a complex structure and is not easy to arrange in a limited stage space. The reliability and stability of the adjustment are poor, and there is a time difference after adjustment, and it is impossible to change to the corresponding wind speed and air volume in time according to the needs of the performance.

[0044] In view of this, an embodiment of the present utility model provides a stage wind effect adjusting device, including: a wind source 100, a connecting pipe 200, and an air outlet assembly 300. The two ends of the connecting pipe 200 are respectively connected to the wind source 100 and the air outlet assembly 300; the air outlet assembly 300 includes a fixing frame 310 and a side plate 320. The fixing frame 310 and the side plate 320 enclose an air outlet structure with an open top. The side plate 320 is provided with an adjusting assembly, and the adjusting assembly can drive the side plate 320 to rotate to adjust the opening size of the air outlet structure.

[0045] When using the stage wind effect adjusting device, the wind source 100 transports cold air into the air outlet assembly 300 through the connecting pipe 200. The side plate 320 is driven to rotate by the adjusting assembly to adjust the opening size of the air outlet structure, thereby adjusting the size of the air outlet volume and presenting the air outlet effect required for stage performances. The stage wind effect adjusting device has a simple structure and is easy to arrange in a limited stage space. The adjustment method of driving the side plate 320 to rotate by the adjusting assembly ensures the reliability and stability of the adjustment, and there is no time difference in the adjustment process, and it can change to the corresponding air volume in a timely manner according to the performance needs.

[0046] In an optional manner of this embodiment, the adjusting assembly includes a motor 410 and an adjusting rod 420. The adjusting rod 420 has a first end and a second end arranged oppositely. The first end is connected to the side plate 320, and the second end extends outside the side plate 320, and the motor 410 is installed at the second end.

[0047] Please refer to Figure 1 , the adjusting rod 420 is arranged parallel to the side plate 320, and the adjusting rod 420 is arranged in the middle of the side plate 320. One side of the adjusting rod 420 abuts against the side plate 320. The first end of the adjusting rod 420 is fixed on the side plate 320, and the second end of the adjusting rod 420 extends outside the side plate 320 and is installed with a motor 410. When adjusting the air volume, the motor 410 drives the second end of the adjusting rod 420 to rotate, thereby driving the side plate 320 to rotate synchronously, so that the opening size of the air outlet structure at the top of the fixing frame 310 and the side plate 320 changes, realizing the adjustment of the air volume. In addition, other common mechanical transmission structures, such as gear-rack transmission, can also be used for the adjusting assembly as long as the rotation of the side plate 320 can be realized, which will not be elaborated here.

[0048] In an optional manner of this embodiment, the fixing frame 310 includes side brackets 311, a bottom bracket 312, and two closed brackets 313. The side brackets 311 are arranged opposite to the side plate 320, the bottom bracket 312 is connected to the connecting pipe 200, the side plate 320 is rotatably connected to the bottom bracket 312, and the two closed brackets 313 are arranged opposite to each other on both sides of the fixing frame 310.

[0049] Please refer to Figure 1, the side brackets 311 and the side plates 320 have the same shape and similar sizes, and they are arranged opposite to each other. The bottom bracket 312 is arranged at the bottom of the fixing bracket 310 and is used to receive the cold air conveyed by the connecting pipe 200. The bottom of the side plate 320 is connected to the bottom bracket 312. Two closing brackets 313 are arranged opposite to each other on both sides of the fixing bracket 310. The cross-section of the closing bracket 313 is trapezoidal and is used to completely enclose both sides of the fixing bracket 310. The side brackets 311, the bottom bracket 312 and the two closing brackets 313 enable the cooperation between the fixing bracket 310 and the side plate 320 to form an opening only at the top for air supply.

[0050] In an alternative embodiment of the present embodiment, the closing bracket 313 is provided with an installation groove on the rotation path of the side plate 320, and the side plate 320 is arranged in the installation groove.

[0051] When the side plate 320 rotates, the surface in contact with the two closing brackets 313 is likely to generate relatively large friction, resulting in wear of the side plate 320 and affecting the air outlet effect. The closing bracket 313 of the present application is provided with an installation groove on the rotation path of the side plate 320, which can effectively reduce the friction between the side plate 320 and the closing bracket 313 during rotation, ensure the air outlet effect, and extend the service life of the device.

[0052] In an alternative embodiment of the present embodiment, the air outlet structure includes an air outlet 330 formed by enclosing the side brackets 311, the side plates 320 and the two closing brackets 313, and the air outlet 330 is strip-shaped.

[0053] Please refer to Figure 1 , the fixing bracket 310 and the side plate 320 form a long strip-shaped air outlet 330 at the top. By rotating the side plate 320, the opening size of the air outlet 330 can be changed, thereby realizing the adjustment of the air volume. When Figure 1 the side plate 320 in rotates clockwise, the opening of the air outlet 330 becomes larger and the air supply volume increases; when Figure 1 the side plate 320 in rotates counterclockwise, the opening of the air outlet 330 becomes smaller and the air supply volume decreases.

[0054] In an alternative embodiment of the present embodiment, the connecting pipe 200 includes a base 210 and an air supply structure. The base 210 is communicated with the air source 100. One end of the air supply structure is installed on the base 210, and the other end is connected to the bottom bracket 312.

[0055] Please refer to Figure 4 , the base 210 is installed on the top of the air source 100. The base 210 is communicated with the air source 100. One end of the air supply structure is communicated with the base 210, and the other end is communicated with the air outlet assembly 300. The cold air generated by the air source 100 enters the air supply structure through the base 210, and then is conveyed to the air outlet assembly 300 through the air supply structure, and finally blows to the outside through the air outlet 330.

[0056] Further, the air supply structure includes a plurality of air supply pipes 220, and the plurality of air supply pipes 220 are arranged at intervals on the bottom bracket 312.

[0057] Please refer to Figure 3 , in this embodiment, the air supply structure includes four air supply pipes 220. One ends of the four air supply pipes 220 are all communicated with the base 210, and the other ends are respectively connected to different positions of the bottom bracket 312, thereby realizing four-way air outlet and enabling the cold air to be evenly blown into the air outlet assembly 300. Of course, more or fewer air supply pipes 220 can also be set, and the specific number of the air supply pipes 220 is not limited here.

[0058] In an alternative embodiment of this embodiment, the air source 100 includes a blower, and the blower is provided with an air outlet, and the air outlet is communicated with the base 210.

[0059] Please refer to Figure 2 , using a blower as the air source 100 effectively reduces the occupied area on the stage and has a good continuous air supply effect. The air outlet of the blower is communicated with the base 210, and the generated air can be continuously conveyed to the connecting pipe 200.

[0060] Further, the blower is installed with a frequency converter.

[0061] The rotation speed of the blower can be controlled through the frequency converter, and then the wind speed at the air outlet 330 can be adjusted to meet the requirements of different scenarios of the stage performance.

[0062] In an alternative embodiment of this embodiment, the stage wind effect adjusting device further includes a controller, and the controller is in signal connection with the motor 410.

[0063] The controller can realize signal control of the motor 410. Through the controller, the rotation direction and rotation speed of the motor 410 can be adjusted, and finally the opening size of the air outlet 330 can be adjusted.

[0064] The overall structure of the stage wind effect adjusting device provided by this embodiment is simple and easy to be arranged in a limited stage space. The adjusting assembly drives the side plate 320 to rotate, ensuring the reliability and stability of the adjustment. There is no time difference in the adjustment process, and the corresponding air volume can be changed in time according to the needs of the performance.

[0065] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
