Description

Technical Field

[0001] The present invention relates to the technical field of stage equipment, and more particularly to a water vortex real-scene stage. Background Art

[0002] The stage is a space provided for actors to perform. It can make the audience focus on the actors' performances and achieve an ideal viewing effect. In order to make the audience's viewing experience and the actors' performances more enjoyable, the stage is usually set up as a lifting type and combined with light and shadow effects to achieve the best viewing effect for the audience. However, with the needs of the performance, in order to make the performance more natural and enable the audience to watch the performance in the real scene, the stage setting usually needs to be designed and built in conjunction with the real scene. For example, a water stage is a common stage built in conjunction with the real scene. The water can make the colorful stage lighting scene make the stage more gorgeous with the help of the reflection in the water, and the fountain can further enhance the shocking effect of the stage. In order to enhance the performance effect, some performances need to immerse the water stage under the water for performance. The existing stage performance effect set up underwater is single and cannot be combined with the real scene to enhance the performance effect. Therefore, there is an urgent need for a stage device that can enhance the performance effect of the real scene water stage.

[0003] Chinese Patent Publication No. CN207583022U, published on December 14, 2017, is titled "An Underwater Lifting and Rotating Stage." The application discloses an underwater lifting and rotating stage comprising a platform support frame and a center stage mounted on the platform support frame; drive assemblies for driving the center stage to rotate are disposed below the platform support frame; a lifting assembly for driving the center stage to rise and fall is also disposed below the platform support frame; the lifting assembly comprises a lifting guide assembly and a lifting linkage assembly; the lifting guide assembly comprises at least one scissor-type lifting support; the lifting linkage assembly comprises multiple rigid supports and a lifting power mechanism for driving the rigid supports to rise and fall; and the stage power mechanism comprises a reduction motor. Although the stage is mounted on water and can rotate, it cannot be combined with the stage to produce a dynamic waterscape effect with a certain degree of performing effect. Summary of the Invention

[0004] The present invention overcomes the deficiency in the prior art that the water stage cannot combine with the real scene to form dynamic water special effects performance effects to improve the performance carrying capacity of the water stage. It provides a water vortex real scene stage, which can control water to generate water vortexes in specific real scene areas in the water, so that the water stage can provide a performance space in the generated water vortex combined with the stage lifting, thereby improving the real scene performance effect of the stage.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a water vortex real-scene stage, comprising: a circular stage, a central stage and a vortex device; the vortex device is used to generate a vortex; the vortex device includes a sleeve, and a water pump is provided in the circumferential direction of the side wall of the sleeve; the central stage can be lifted and lowered and accommodated in the sleeve; the circular stage is arranged on the periphery of the sleeve.

[0006] In order to coordinate the stage with the real scene and improve the performance effect of the real scene, the present invention provides a vortex device on the periphery of the central stage. The vortex device is provided with a water pump under the sleeve, and water is quickly pumped out of the sleeve by the water pump, so that a water vortex effect is generated at the central stage, thereby improving the real scene performance effect of the stage. After the water in the sleeve is pumped out, the water level in the sleeve gradually decreases. At the same time, the central stage also gradually descends as the water level in the sleeve gradually decreases, thereby generating a water vortex effect that converges from the surroundings to the center and from high to low, thereby creating a space for stage real scene performances, which can enrich the content of the program or increase the viewing effect.

[0007] Preferably, a lifting frame is provided below the central stage, the lifting frame is provided in the sleeve, rollers are provided in the circumferential direction of the lifting frame, a guide rod is provided in the sleeve, the rollers are in contact with the guide rod and can roll up and down along the guide rod; a steering pulley is provided on the guide rod, a lifting cable is connected to the lifting frame, one end of the lifting cable is connected to the lifting frame, and the other end of the lifting cable is connected to the motor through the steering pulley.

[0008] The motor drives the lifting cables to move, so that the center stage can be pulled up and down by the lifting cables, thereby controlling the lifting of the center stage; the cooperation between the guide rod and the roller can make the lifting frame more stable when moving up and down along the guide rod, thereby making the up and down movement of the center stage more stable.

[0009] Preferably, a water retaining ring is provided on the outer circumference direction of the sleeve, and the water retaining ring is connected to a lifting device.

[0010] Because the height of the outdoor water surface is affected by weather and climate, causing the water level to fluctuate, a water retaining ring can be installed to block the water outside the circumference of the center stage. At the same time, by controlling the height of the water retaining ring, when a water vortex is generated, the flow of water from the surrounding areas to the center stage can be controlled, ensuring the water vortex is generated.

[0025] Preferably, a rubber water pipe is provided between the water retaining ring and the sleeve.

[0026] The rubber water tube can fill the gap between the water retaining ring and the sleeve. When working normally, the rubber water tube injects water at a certain flow rate, so that the rubber water tube is in an expanded state to reduce the gap between the water retaining ring and the sleeve, reduce the amount of water flowing between the water retaining ring and the sleeve, and thus form a water vortex effect faster.

Therefore, the present invention uses a steering cable to realize the lifting and lowering of the center stage; a hydraulic motor is used as power to enable the rotating device to rotate, thereby improving the service life of the power mechanism; when water is pumped out of the sleeve by a water pump, the water flows and converges to the center stage.

[0053] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0054] Example 1: Reference Figures 1 to 5 As shown, a water vortex real scene stage includes:

[0055] The circular stage 1 is fixed by a fixing column 11 and a fixing bracket 12;

[0056] The center stage 2 is liftable and located in the center of the circular stage 1;

[0057] The vortex device 3 is used to generate a vortex. The vortex device 3 includes a sleeve 31. Water pumps 32 are arranged in the circumferential direction of the side wall of the sleeve 31. The water pumps 32 are evenly arranged along the circumferential direction of the sleeve 31. The central stage 2 can be accommodated in the sleeve 31 and can be raised and lowered. The circumferential stage is arranged on the periphery of the sleeve 31.

[0058] Among them, the uppermost part of the sleeve 31 is located below the water surface, and the water in the sleeve 31 is quickly discharged to the outside of the sleeve 31 through the water pump 32. As the water level in the sleeve 31 gradually drops, a water vortex is generated in the sleeve 31, and at the same time, water can flow into the sleeve along the side wall of the sleeve 31. The uppermost part of the sleeve 31 is located between 5 cm and 15 cm below the water surface.

[0059] In order to coordinate the stage with the real scene and improve the performance effect of the real scene, the present invention provides a vortex device 3 on the periphery of the central stage 2. The vortex device 3 is provided with a water pump 32 below the sleeve 31. The water pump 32 quickly pumps water out of the sleeve 31, so that a water vortex effect is generated at the central stage 2, thereby improving the real scene performance effect of the stage. After the water in the sleeve is pumped out, the water level in the sleeve gradually decreases. At the same time, the central stage 2 also moves downward as the water level in the sleeve gradually decreases, thereby generating a water vortex effect that converges from the surroundings to the center and from high to low, thereby creating a space for stage real scene performances, which can enrich the content of the program or increase the viewing effect.

[0060] A lifting frame 21 is provided below the central stage 2. The lifting frame 21 is provided in a sleeve 31. Rollers 22 are provided in the circumferential direction of the lifting frame. A guide rod 23 is provided in the sleeve 31. The rollers 22 abut against the guide rod 23 and can roll up and down along the guide rod. A steering pulley 231 is provided on the guide rod 23. A lifting cable 24 is connected to the lifting frame 21. One end of the lifting cable 24 is connected to the lifting frame 21, and the other end of the lifting cable 24 is connected to the motor through the steering pulley 231.

[0061] The motor drives the lifting cable 24 to move, so that the center stage 2 can be pulled up and down by the lifting cable 24, thereby controlling the lifting and lowering of the center stage 2; the cooperation between the guide rod 23 and the roller 22 can make the lifting frame 21 more stable when moving up and down along the guide rod 23, thereby making the up and down movement of the center stage more stable.

[0062] The circular stage includes several fixed columns 11, fixed brackets 12, several fan-shaped platforms 13 and a slope 14; the circular stage is composed of several fan-shaped platforms 13 in the circumferential direction; the fan-shaped platform 13 is provided with wheels 15, which can be raised and lowered along the slope 14; the slope 14 is set on the fixed bracket 12, and the fixed bracket 12 is set on the periphery of the sleeve 31 through the fixed column 11.

[0063] Example 2, reference Figures 1 to 5 As shown, this embodiment is similar in structure to the embodiment 1, except that a water retaining ring 4 is provided on the outer circumference of the sleeve, and the water retaining ring 4 is connected to a lifting device 5.

[0064] The lifting device 5 comprises:

[0065] A lifting rod 51 is fixedly connected to the water retaining ring 4, and a lifting wheel 511 is provided on the lifting rod 51;

[0066] The annular pull rod 52 is connected to a traction device, and the traction device drives the annular pull rod 52 to perform circular motion;

[0067] The lifting wheel assembly 53 is fixedly connected to the sleeve 31. The lifting wheel assembly 53 includes a first lifting wheel 531. A second lifting wheel 532 and a third lifting wheel 533 are respectively provided on both sides of the first lifting wheel 531;

[0068] The cable assembly includes a first cable 541 and a second cable 542. One end of the first cable 541 is fixedly connected to the first fixed lock platform 521 provided on the annular pull rod 52, and the other end passes through the second lifting wheel 532, the first lifting wheel 531, and the lifting wheel 511 in sequence and is fixedly connected to the lifting rod 51. One end of the second cable 542 is fixedly connected to the second fixed lock platform 522 provided on the annular pull rod 52, and the other end passes through the third lifting wheel 533 and is connected to the lifting rod 51.

[0069] Among them, the annular pull rod 52 is driven to rotate by the traction device, and the annular pull rod 52 pulls the first cable 541 and the second cable 542 to move, so that the water retaining ring 4 is raised and lowered. Generally, when the water retaining ring is controlled in a long-term state, the upper edge of the water retaining ring 4 is kept between 5cm and 15cm below the water surface.

[0070] When the annular pull rod 52 rotates to the left, the first fixed locking platform 521 pulls the first cable 541 to move, and the action of the first cable 541 causes the lifting wheel 511 to move upward, thereby realizing the rising of the water retaining ring 4; similarly, when the annular pull rod 52 rotates to the right, the second fixed locking platform 522 pulls the second cable 542 to move, and at the same time the first cable 541 is reset, and at the same time the second cable 542 pulls the lifting rod 51 downward, thereby realizing the downward movement of the water retaining ring 4.

[0071] The traction device includes:

[0072] Traction winch 61, providing power for the traction device;

[0073] The pull rod roller 62 is fixedly arranged on the annular pull rod 52, and the pull rod roller 62 includes a left pull rod roller 621 and a right pull rod roller 622;

[0074] The steering roller 63 is used to provide a steering force for the annular pull rod 52. The steering roller 63 includes a left steering roller 631 and a right steering roller 632.

[0075] The steering cable 64 has one end connected to the first tightening screw 65 fixed on the sleeve 31, and the other end passes through the left pull rod roller 621, multiple left steering rollers 631, the traction winch 61, multiple right steering rollers 632, the right pull rod roller 622 in sequence and is connected to the second tightening screw 66 set on the sleeve 31.

[0076] The steering cable 64 is a long cable. In this embodiment, there are two steering cables 64, the middle of which is wound on the traction winch 61. The two ends of the steering cable 64 are connected to the annular rod 52, and the two ends are respectively connected to the opposite sides of the annular rod 52. There is a certain distance between the two ends so that the two ends can pull the annular rod 52 to move. When the traction winch 61 rotates, one end of the steering cable 64 is extended and the other end is contracted, so that the annular rod 52 can be pulled to move. When the traction winch 61 rotates in the opposite direction, the traction winch 61 also drives the annular rod 52 to rotate in the opposite direction through the steering cable 64, thereby easily realizing the rotation of the annular rod 52.

[0077] The annular pull rod 52 is provided with a pulley set 67 in its circumferential direction. The pulley set 67 includes a first pulley 671 and a second pulley 672. The first pulley and the second pulley are respectively provided with grooves. The first pulley 671 and the second pulley 672 are overlapped and the annular pull rod 52 is arranged between the grooves of the first pulley 671 and the second pulley 672.

[0078] The annular pull rod 52 is set between the first pulley 671 and the second pulley 672. Through the action of the first pulley 671 and the second pulley 672, the position of the annular pull rod in the height direction can be kept unchanged, and the circular rotation of the annular pull rod 52 can be smoother and easier.

[0079] A rubber water tube 41 is provided between the water retaining ring 4 and the sleeve 31, and the rubber water tube 41 is along the outer edge of the sleeve 31 and fixed thereto; in order to achieve a better caulking effect, the rubber water tube 41 can be filled with water to make it in a swollen state; when the water retaining ring 4 is raised or lowered, water is discharged from the rubber water tube 41, which can reduce friction resistance and reduce the friction between the rubber water tube 41 and the water retaining ring 4, thereby increasing the service life of the rubber water tube 41.

[0080] The rubber water tube 41 can fill the gap between the water retaining ring 4 and the sleeve 31. When the rubber water tube 41 is full of water, the amount of water flowing between the water retaining ring 4 and the sleeve 31 can be reduced, thereby forming a water vortex effect more quickly.

[0081] Example 3, reference Figures 6 to 10This embodiment is similar in structure to the embodiment 2, except that a rotating device 8 is provided on the central stage. The rotating device 8 is connected to the lifting frame 211 via a slewing bearing 9 with an external gear, which is nested in the middle of the lifting frame 211. The external gear portion is fixedly connected to the rotating device.

[0082] The lifting frame is fixedly provided with a hydraulic motor 10. The output end of the hydraulic motor 10 is provided with a driving gear 101 meshing with the external gear of the slewing support to drive the circumferential motion of the slewing support with the external gear part, thereby causing the rotating device to generate rotational motion.

[0083] The rotating device 8 comprises:

[0084] The outer ring frame 81 is connected to the lifting frame 21 via a slewing bearing 9;

[0085] The inner ring frame 82 is arranged at the center of the outer ring frame 81; the outer ring frame and the inner ring frame are fixedly connected;

[0086] The blade plates 83 are evenly arranged along the circumference between the inner and outer ring frames 82 and 81. The blade plates 83 include blades 832 and a rotating shaft 831. The rotating shaft 831 is provided through the side walls of the inner and outer ring frames 82 and 81. A key block 84 is provided between the rotating shaft 831 and the side wall of the outer ring frame 81. The outer ring frame 81 is provided with a through hole on the circumference, and the rotating shaft 831 is provided in the through hole. The inner side wall of the through hole is provided with a keyway. The blade plates 83 are arranged at an angle.

[0087] The side wall of the sleeve 31 is provided with a plurality of through holes for leading lifting cables and the like out of the sleeve.

[0088] A follow-up lifting fountain 102 is provided in the middle of the central stage.

[0089] In the prior art, the rotation of the stage is achieved by rotating the motor. However, since the motor is placed in water in the prior art, it is easy to be damaged if placed in water for a long time. Therefore, a rotating device 8 is provided in the present invention. Through the inclined fan plate 83, when the center stage is rising or falling, the rotating device 8 is rotated by the action of water and the inclined fan plate 83, thereby achieving the effect of forming a dynamic water vortex.

[0090] In order to make the stage match the real scene and improve the performance effect of the real scene, the present invention sets a vortex device 3 on the periphery of the central stage 2. The vortex device 3 is provided with a water pump 32 under the sleeve 31. The water pump 32 quickly pumps water out of the sleeve 31, so that a water vortex effect is generated at the center of the central stage 2, thereby improving the real scene performance effect of the stage. The circular stage 1 is set on the periphery of the sleeve. The circular stage can be raised and lowered along the slope so that the circular stage can meet the requirements of the stopping position at the lowest water level and the highest water level. After the water in the sleeve is pumped out, This allows water to flow from the surrounding areas of the sleeve to the center. At this time, the central stage 2 is lowered so that the central stage 2 is lower than the circular stage 1, thereby generating a water vortex effect that converges from the surrounding areas to the center and from high to low, making the effect of the stage live performance better; at the same time, a water retaining ring 4 that can be raised and lowered is provided to control the water flow in the central stage 2 and the size of the water vortex; at the same time, a rotating device 8 is provided below the central stage 2, and the hydraulic motor drives the slewing bearing to rotate, and the rotating device follows to rotate the fan blade 83, which can generate a more intense dynamic water vortex.
