Description

Technical Field

[0001] The present invention relates to the technical field of stage devices, and in particular to a reciprocatingly opening and closing stage mechanical device. Background Art

[0002] In order to enhance the performance effect, part of the stage is built in the water, and lights, fountains, etc. are used to create a magnificent and beautiful artistic scene.

[0003] like Figure 1 The figure shows a schematic diagram of the structure of a water stage in the prior art. The stage is built in a pool with an underground area below. An opening is provided on the stage to accommodate performers from the underground area. Under normal circumstances, the opening is sealed by a partition. During a performance, the performers enter the underground area in advance and move up a ladder to a lift. The partition on the stage then opens to reveal the opening. The lift lifts the performers through the opening to the stage for the performance. However, since most of the mechanical equipment and electronic products required for the stage are installed in the underground area, the heat generated during operation of the mechanical equipment and electronic products causes the underground area to be hot. When the partition is opened, the underground area releases some hot air at the opening. In autumn and winter, the outside air temperature is lower, and the surface temperature of the partition used to separate the opening is also lower. When the partition is closed, the hot air in the opening contacts the partition surface, condensing a large amount of water droplets on the partition surface, making the partition surface slippery. This not only easily causes rust on the mechanical components that open and close the partition, but also may cause accidents during the performance. Summary of the Invention

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 2-9 A reciprocating stage mechanical device includes a mounting plate 1, a track 2 is fixedly connected to the mounting plate 1, two plates 3 are slidably fitted on the track 2, an electric cylinder 4 is provided on the mounting plate 1, a movable rod 5 is fixedly connected to the output end of the electric cylinder 4, a piston 9 is fixedly connected to the movable rod 5, a blind hole 302 is opened on the plate 3, the piston 9 is slidably fitted in the blind hole 302, and a spring 6 is sleeved on the movable rod 5 to apply elastic force to the plate 3.

[0027] When the device is in use, the mounting plate 1 is fixed on the stage, and the movable rod 5 is driven to move by the electric cylinder 4. When the movable rod 5 moves, it drives the plate 3 to move, thereby changing the distance between the two plates 3 to control the opening and closing of the opening on the stage, wherein:

[0028] Control the closing process of the opening: the movable rod 5 first applies force to the spring 6. After the spring 6 is subjected to the force, it drives the plate 3 to slide on the track 2, so that the two plates 3 move closer to each other. When the two plates 3 move until they are against each other, the movable rod 5 will continue to move a distance. At this time, the movable rod 5 will compress the spring 6 while driving the piston 9 to slide into the blind hole 302. The sliding of the piston 9 into the blind hole 302 will compress the air in the blind hole 302, thereby increasing the air pressure in the blind hole 302.

[0029] Control the opening process of the opening: the movable rod 5 first drives the piston 9 to slide outward from the blind hole 302. The sliding of the piston 9 outward from the blind hole 302 will reduce the air pressure in the blind hole 302. A one-way valve is provided at the bottom of the blind hole 302. Under the action of atmospheric pressure, the outside air enters the blind hole from the one-way valve. During this process, the spring 6 is in a compressed state. Under the action of the elastic force of the spring 6, the two plates 3 remain in contact with each other. When the piston 9 moves to the maximum distance, the spring 6 returns to its initial state. As the movable rod 5 continues to move, the movable rod 5 will drive the two plates 3 to move through the piston 9, thereby moving the two plates 3 away from each other to open the opening.

[0030] like Figure 6-12 As shown, a mounting groove 303 is provided on the plate 3, and the blind hole 302 is connected to the mounting groove 303. A rotating body 7 is slidably fitted in the mounting groove 303, and an air gap 701 is provided on the rotating body 7 to accommodate the air in the mounting groove 303 to be discharged to the outside.

[0031] Based on the above description, it can be seen that the air pressure in the blind hole 302 increases during the closing process of the control opening. Since the blind hole 302 is connected to the mounting groove 303, the air pressure in the mounting groove 303 will also increase. Under the action of the air pressure, the rotating body 7 in the mounting groove 303 will slide upward, and the output end of the rotating body 7 rises to the top of the air gap 701 and is higher than the stage surface. At this time, the air in the mounting groove 303 will be discharged to the outside through the air gap 701, and the output end of the air gap 701 faces obliquely downward. The air discharged from the air gap 701 will blow toward the upper surface of the plate 3, thereby drying the water droplets attached to the upper surface of the plate 3.

[0032] like Figure 2-3 As shown, a water storage tank 301 is provided on the surface of the plate 3. Smaller water droplets will dry quickly under the action of wind, while larger water droplets will be blown into the water storage tank 301 by the wind to prevent the surface of the plate 3 from being wet and slippery.

[0033] like Figure 10-12 As shown, a bushing 304 is fixed in the mounting groove 303, and an inner spline sleeve 703 is slidably engaged in the bushing 304. The inner spline sleeve 703 is fixed to the rotating body 7. A through hole 702 is provided on the top of the rotating body 7. A flow channel 704 is provided on the inner spline sleeve 703 to accommodate the air in the mounting groove 303 to flow into the through hole 702. A spline shaft 11 is rotatably installed in the mounting groove 303, and the spline shaft 11 is slidably engaged in the inner spline sleeve 703. A stopper 12 is fixed to the spline shaft 11, and the stopper 12 is slidably engaged in the through hole 702.

[0034] In the initial state, the stopper 12 is located in the through hole 702 to seal the through hole 702 to prevent external impurities from clogging the through hole 702 .

[0035] During the rising process of the rotating body 7, the block 12 will be pulled out from the through hole 702, so that the through hole 702 is opened. After the through hole 702 is opened, part of the air in the installation groove 303 will enter the through hole 702 through the flow channel 704 and be discharged to the outside from the through hole 702. Since the output end of the through hole 702 is facing upward, the air discharged from the through hole 702 will blow above the plate 3, thereby blowing away the water droplets formed above the plate 3 due to the convection of cold and hot air, so as to prevent the condensed water droplets in the air from falling on the plate 3 under the action of gravity.

[0036] like Figure 9 and Figure 13 As shown, a gear 8 is rotatably mounted on the plate 3, a rack 10 is fixedly connected to the movable rod 5, the rack 10 matches the gear 8, a driven sprocket 13 is fixedly connected to the spline shaft 11, a driving sprocket 15 is coaxially fixed to the gear 8, and a chain 14 is mounted on the driving sprocket 15 and the driven sprocket 13 in cooperation with each other.

[0037] During the displacement of the movable rod 5 relative to the plate 3, the rack 10 on the movable rod 5 will drive the gear 8 to rotate, and the rotation of the gear 8 will drive the driving sprocket 15 to rotate. During the rotation of the driving sprocket 15, the driven sprocket 13 will be driven to rotate through the chain 14. The rotation of the driven sprocket 13 will drive the spline shaft 11 to rotate, and the rotation of the spline shaft 11 will drive the inner spline sleeve 703 to rotate. Since the inner spline sleeve 703 and the rotating body 7 are fixedly connected, the rotation of the inner spline sleeve 703 will drive the rotating body 7 to rotate, thereby causing the airflow ejected from the air gap 701 to rotate, so as to perform multi-directional drying on the upper surface of the plate 3.

[0038] Working principle and workflow:

[0039] The device is installed at the opening of the stage through the installation plate 1, and the two plates 3 are pressed against each other to close the opening.

[0040] S1: During the performance, the actors move from under the stage to the opening via a lifting platform. During this process:

[0041] The electric cylinder 4 controls the opening process of the opening. The electric cylinder 4 drives the movable rod 5 to move. The movable rod 5 first drives the piston 9 to slide outside the blind hole 302. The sliding of the piston 9 outside the blind hole 302 will reduce the air pressure in the blind hole 302. A one-way valve is provided at the bottom of the blind hole 302. Under the action of atmospheric pressure, the outside air enters the blind hole from the one-way valve. During this process, the spring 6 is in a compressed state. Under the action of the elastic force of the spring 6, the two plates 3 remain in contact with each other. When the piston 9 moves to the maximum distance, the spring 6 returns to its initial state. As the movable rod 5 continues to move, the movable rod 5 will drive the two plates 3 to move through the piston 9, thereby moving the two plates 3 away from each other to open the opening.

[0042] S2: After the lift platform rises from the opening, the performers move from the lift platform to the stage to perform, while the lift platform resets. During this process:

[0043] The electric cylinder 4 controls the closing process of the opening: the electric cylinder 4 drives the movable rod 5 to move, and the movable rod 5 first applies force to the spring 6. After the spring 6 is subjected to the force, it drives the plate 3 to slide on the track 2, thereby making the two plates 3 approach each other. When the two plates 3 move until they are against each other, the movable rod 5 will continue to move a distance. At this time, the movable rod 5 will compress the spring 6 while also driving the piston 9 to slide into the blind hole 302.

[0044] S21: The piston 9 slides into the blind hole 302 to compress the air in the blind hole 302, thereby increasing the air pressure in the blind hole 302.

[0045] Since the blind hole 302 is connected to the mounting groove 303, the air pressure in the mounting groove 303 will also increase. Under the action of the air pressure, the rotating body 7 in the mounting groove 303 will slide upward, and the output end of the rotating body 7 rises to the top of the air gap 701 and is higher than the stage surface. At this time, the air in the mounting groove 303 will be discharged to the outside through the air gap 701, and the output end of the air gap 701 faces obliquely downward. The air discharged from the air gap 701 will blow toward the upper surface of the plate 3, thereby drying the water droplets attached to the upper surface of the plate 3.

[0046] A water storage tank 301 is provided on the surface of the plate 3. Smaller water droplets will dry quickly under the action of wind, while larger water droplets will be blown into the water storage tank 301 by the wind to prevent the surface of the plate 3 from being wet and slippery.

[0047] During the rising process of the rotating body 7, the block 12 will be pulled out from the through hole 702, so that the through hole 702 is opened. After the through hole 702 is opened, part of the air in the installation groove 303 will enter the through hole 702 through the flow channel 704 and be discharged to the outside from the through hole 702. Since the output end of the through hole 702 is facing upward, the air discharged from the through hole 702 will blow above the plate 3, thereby blowing away the water droplets formed in the air above the plate 3 due to the convection of cold and hot air, so as to prevent the condensed water droplets in the air from falling on the plate 3 under the action of gravity.

[0048] S22: During the sliding of the piston 9 into the blind hole 302, the rack 10 on the movable rod 5 drives the gear 8 to rotate, and the rotation of the gear 8 drives the driving sprocket 15 to rotate. During the rotation of the driving sprocket 15, the driven sprocket 13 is driven to rotate through the chain 14. The rotation of the driven sprocket 13 drives the spline shaft 11 to rotate, and the rotation of the spline shaft 11 drives the inner spline sleeve 703 to rotate. Since the inner spline sleeve 703 is fixedly connected to the rotating body 7, the rotation of the inner spline sleeve 703 drives the rotating body 7 to rotate, thereby causing the airflow ejected from the air gap 701 to rotate, so as to perform multi-directional air drying on the upper surface of the plate 3.

[0049] S3: After the performance, the actors move behind the scenes, and the next group of actors move to the lift platform in the underground area and repeat S1-S2 above.
