[0017] This utility model provides a projection shutter device, including: a control component, a transmission component, and a light-blocking component. The control component is signal-connected to the transmission component, and the transmission component is drive-connected to the light-blocking component. The light-blocking component is disposed in front of the projector lens.

[0031] Example 1
[0032] During stage performances, projectors are frequently used to project onto the stage. The projector's chip is relatively fragile. When the projector lens is exposed to strong light such as lasers projected from the stage during the performance, it may damage the projector's chip through the projection optical path, causing the projector to malfunction and affecting the normal progress of the performance.
[0033] In view of this, the present invention provides a projection shutter device, including: a control component, a transmission component, and a light-blocking component. The control component is signal-connected to the transmission component, the transmission component is drive-connected to the light-blocking component, and the light-blocking component is disposed in front of the lens of the projector 200. The light-blocking component can move to the front of the lens of the projector 200 under the action of the control component and the transmission component to block the lens of the projector 200.
[0034] During a stage performance, when strong light such as laser light projected from the stage shines on the lens of projector 200, a control signal is sent from the control component to the transmission component. Since the transmission component is connected to the light-blocking component, the light-blocking component moves to directly in front of the projector 200 lens, blocking it and preventing the strong light from damaging the projector 200's chip through the projection optical path. When the strong light from the stage stops and projection onto the stage is needed, the control component sends another control signal to the transmission component, causing the light-blocking component to move away from the projector 200 lens, no longer blocking it. The projector 200 then projects onto the stage normally through the projection optical path. The projection shutter device, by blocking the projector 200 lens with the light-blocking component, prevents the projector 200's chip from being damaged by the strong light from the stage, ensuring the normal operation of the projector 200 and the smooth running of the performance.
[0035] In an optional embodiment, the control component includes a control switch 100, which is located in the control room 110 and is signal-connected to the transmission component.
[0036] Please see Figure 1 The control room 110 is equipped with a control switch 100, which allows staff to remotely control the movement of the transmission components from inside the control room 110, thereby controlling the light-blocking components to block or move the projector 200 lens.
[0037] In an optional embodiment, the control component further includes a solenoid valve 300, which is signal-connected to the control switch 100 and is disposed in the air path of the transmission component.
[0038] Please see Figure 1 The control switch 100 can control the opening and closing of the solenoid valve 300, thereby controlling whether the air passage of the transmission component is connected. When the solenoid valve 300 is connected, the air passage of the transmission component is open, and the transmission component drives the light-blocking component to move directly in front of the lens of the projector 200, blocking the lens of the projector 200; when the solenoid valve 300 is disconnected, the air passage of the transmission component is disconnected, and the transmission component drives the light-blocking component to move away from the lens of the projector 200, no longer blocking the lens of the projector 200.
[0039] In an optional embodiment, the transmission component includes a pneumatic telescopic rod 400, which is connected to the solenoid valve 300 via an air circuit. The pneumatic telescopic rod 400 controls its movement path by opening and closing the solenoid valve 300.
[0040] The pneumatic telescopic rod 400 and the solenoid valve 300 are set in the same air circuit. When the solenoid valve 300 is connected, the air circuit of the pneumatic telescopic rod 400 is open. When the pneumatic telescopic rod 400 moves, it drives the light-blocking component to move to the front of the projector 200 lens. When the solenoid valve 300 is disconnected, the air circuit of the pneumatic telescopic rod 400 is disconnected. When the pneumatic telescopic rod 400 returns to its original position, it drives the light-blocking component to move away from the projector 200 lens.
[0041] In an optional embodiment, the projection shutter device further includes a fixed frame 500, and a pneumatic telescopic rod 400 is slidably mounted on the fixed frame 500.
[0042] Please see details. Figure 2The mounting bracket 500 has a guide groove 600 along its height, and the pneumatic telescopic rod 400 slides in conjunction with the guide groove 600. When the air passage of the pneumatic telescopic rod 400 is open, it slides downward along the guide groove 600, causing the light-blocking component to move downward to the front of the projector 200 lens. When the air passage of the pneumatic telescopic rod 400 is closed, it slides upward along the guide groove 600 to reset, causing the light-blocking component to move upward and move away from the projector 200 lens.
[0043] In an optional embodiment, the light-blocking component includes a light-blocking plate 700, the top of which is connected to the pneumatic telescopic rod 400.
[0044] Please continue reading Figure 2 The light-blocking plate 700 has a rectangular cross-section, and its top is detachably connected to the bottom of the pneumatic telescopic rod 400. When the pneumatic telescopic rod 400 slides downward along the guide groove 600, the light-blocking plate 700 simultaneously moves downward to the front of the projector 200 lens, blocking the lens. When the pneumatic telescopic rod 400 slides upward along the guide groove 600 to reset, the light-blocking plate 700 simultaneously moves upward to move away from the projector 200 lens, allowing the projector 200 to project normally towards the stage.
[0045] In an optional embodiment, the projection shutter device further includes an air compressor 800, which is connected to the solenoid valve 300 via an air intake pipe.
[0046] Please see Figure 1 The air compressor 800 provides power to the air passages of the solenoid valve 300 and the pneumatic telescopic rod 400, enabling the pneumatic telescopic rod 400 to slide downward or upward along the guide groove 600 to reset.
[0047] In an optional embodiment, an oil-water separator 900 is provided on the intake pipe.
[0048] Please see Figure 1 Installing an oil-water separator 900 on the air intake pipe can better protect the normal operation of the pneumatic telescopic rod 400, ensuring the normal operation of the projection shutter device.
[0049] Furthermore, the air compressor 800 is connected to the projector 200. While providing power to the air circuits of the solenoid valve 300 and the pneumatic telescopic rod 400, the air compressor 800 can also provide power to the projector 200, effectively saving energy.
[0050] It should be noted that the air compressor 800 and the projector 200 are two relatively independent structures, and they are connected by a bracket.
[0051] It should also be noted that, please refer to Figure 1Two projectors 200 can be set up, namely the main projector and the auxiliary projector, and the two are controlled by a projection shutter device to ensure the smooth running of the performance.
[0052] The projection shutter device provided in this embodiment is used as follows:
[0053] When strong light, such as laser light, projected from the stage shines on the lens of projector 200, the operator in control room 110 activates solenoid valve 300 via control switch 100. Pneumatic telescopic rod 400 slides downward along guide groove 600, and light-blocking plate 700 simultaneously moves downward to the front of projector 200's lens, blocking it and preventing the projected laser light from damaging the projector 200's chip through the projection optical path. When the stage light stops and projecting onto the stage is needed, the operator in control room 110 deactivates solenoid valve 300 via control switch 100. Pneumatic telescopic rod 400 slides upward along guide groove 600 to reset, and light-blocking plate 700 simultaneously moves upward to move away from projector 200's lens, allowing projector 200 to project normally onto the stage.
[0054] The projection shutter device uses a light-blocking plate 700 to shield the lens of the projector 200, preventing the chip of the projector 200 from being damaged by strong light such as lasers projected from the stage, thus enabling the projector 200 to function normally and ensuring the smooth running of the performance.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
