Abstract
Description
Technical Field
[0001] This utility model relates to the field of performing arts equipment, specifically a multi-degree-of-freedom collaborative fire pot flame performance device. Background Technology
[0002] Both the fire-bottle performance and the charcoal spark dance are highly distinctive traditional performing arts forms, holding significant importance in cultural inheritance and artistic expression. Their performance styles are remarkably similar, both involving performers holding hollowed-out containers filled with charcoal or similar luminous and heat-generating substances. Through exquisite dancing skills, they create dazzling trails of sparks in the air, delivering a visually stunning and breathtaking artistic experience to the audience.
[0003] In current performance practice, both kettle-fire performances and charcoal flower dances face severe challenges. From the performers' perspective, these performances demand extremely high physical fitness. Performers need extensive professional training and robust physiques to master the art. During performances, performers hold heavy containers for extended periods and must complete a series of complex, high-intensity movements, resulting in significant physical exertion and easy fatigue. The risk of injury increases significantly with prolonged or frequent performances. For example, in large-scale cultural events, performers are highly susceptible to strain injuries in key areas such as the wrists and shoulders after multiple consecutive performances.
[0004] From a performance perspective, it's difficult to ensure the precision and consistency of every movement in a human performance. Different performers have varying skill levels, leading to discrepancies in the trajectory and rhythm of sparks. Furthermore, due to limitations in human physiology, traditional performance styles face bottlenecks in terms of movement innovation, making it difficult to break through existing patterns and present audiences with entirely new visual experiences. Additionally, in multi-person performances, if performers are too far apart, the overall performance effect is relatively poor. Conversely, if performers are too close, the risk of burns increases.

[0051] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0052] Please see Figures 1-5 This application provides the following technical solutions:
[0053] A multi-degree-of-freedom collaborative fire pot flame performance device includes a first support unit 1 serving as the bottom structure of the device, which also acts as the overall support structure. A second support unit 2 is mounted on the first support unit 1, supporting a fire pot unit 3 and a first action unit 4 used for the performance. The fire pot unit 3 includes a container 31 with an internal cavity and mesh openings in its cavity walls. The container 31 can hold the incendiary material used in the fire pot performance or charcoal flower dance. The container 31 can be made of a material unaffected by the internal incendiary material, such as copper, iron, or high-temperature alloys, and can be a mesh cage structure. The shape of the container 31 is not limited, as long as it has an opening for placing the incendiary material. The overall shape can be a closed-end cylinder or other polygonal structures. This design uses a cylindrical shape. Each teapot unit 3 can be equipped with multiple containers 31, with container connectors 32 positioned between them. It's important to note that, considering dynamic balance during performances, when multiple containers 31 are used, they should be evenly distributed in a circle around the center of the container connector 32. This design uses a structure where each teapot unit 3 has two containers 31, and the container connector 32 is a rod positioned between the two containers 31. An opening for placing burning material is provided on one side of each of the two containers 31. The device also includes a first actuation unit 4, which is mounted on the second support unit 2. The teapot unit 3 is mounted on the first actuation unit 4, which drives the movement of the containers 31 within the teapot unit 3 to achieve teapot flame performances or charcoal flower dances. The first actuation unit 4 in this design performs a rotational action. The first actuation unit 4 and the container connector 32 are linked at the middle, causing all containers 31 on the same teapot unit 3 to rotate synchronously. The first actuating unit 4 in this design is a rotary DC motor with an adjustable speed of 0-60 rpm, such as the Festo EMMS-AS-55 servo cylinder. The container connector 32 in this design is a high-temperature resistant alloy rod that can withstand operating temperatures ≥800℃.
[0054] Based on the above implementation scheme, the first supporting unit 1 includes a first supporting structure 11 and a moving mechanism 12. The upper part of the first supporting structure 11 is connected to the second supporting unit 2. The lower part of the first supporting structure 11 is connected to the moving mechanism 12, which drives the first supporting structure 11 to move. The moving mechanism 12 can take various forms, such as ground, water, or air movement, or it can be an amphibious composite moving mechanism, which can be selectively used according to actual needs.
[0055] The moving mechanism 12 used in this solution is a tracked moving mechanism. The moving mechanism 12 includes two sets of track assemblies, one set symmetrically arranged on each side of the first support structure 11. The structure of the track assembly itself can adopt existing track structures; the specific structure of the track assembly is not the focus of this solution's improvement and will not be elaborated here. The track assembly supports XY-axis translation and θ-axis rotation. The moving mechanism 12 is equipped with a drive motor, encoder, battery, etc., to control its movement trajectory. The motor of the moving mechanism 12 can be a Maxon EC60 motor.
[0056] Based on the above implementation scheme, the second supporting unit 2 includes a supporting platform 21, which is rotatably connected to the first supporting structure 11. A second actuating unit 5 is provided between the first supporting structure 11 and the second supporting unit 2. The second actuating unit 5 is linked to the supporting platform 21 of the second supporting unit 2, and can drive the supporting platform 21 to rotate. The axis of rotation of the supporting platform 21 is perpendicular to its own platform surface; taking the supporting platform 21 in a horizontal state as an example, the axis of rotation is vertical. A heat insulation layer is provided on the upper side of the supporting platform 21 to protect the moving mechanism 12 on the lower side.
[0057] The second action unit 5 includes a 180° double-acting pneumatic rotary cylinder with a maximum torque of ≥50 N·m, which meets the positioning accuracy of ±0.5° for the support platform 21, such as the Festo DSBC-32-180 cylinder.
[0058] Based on the above implementation scheme, a second support structure 22 is fixedly installed on the support platform 21. The second support structure 22 only needs to provide sufficient support force, and its specific form is not limited. The rotary DC motor of the first action unit 4 is installed on the second support structure 22, and the container connector 32 of the kettle unit 3 is linked with the movable end of the cylinder.
[0059] The second support structure 22 of this scheme is a "door" shaped frame set on the support platform 21. The second support structure 22 extends upward toward the support platform 21. A mounting seat is provided on the second support structure 22 corresponding to the first action unit 4, which facilitates the connection between the first action unit 4 and the kettle unit 3.
[0060] Based on the above implementation scheme, the second support structure 22 includes a fixed frame and a movable frame. The fixed frame is the aforementioned "door" shaped frame, including two uprights and a top plate located at the top of the two uprights. The two ends of the top plate are perpendicular to the uprights. A first action unit 4 and a kettle unit 3 are fixedly installed in the middle of the top plate.
[0061] A movable frame is slidably connected to the fixed frame. Both ends of the movable frame are slidably connected to two uprights, using methods such as guide rail connection or sleeve connection. The movable frame moves up and down between the support platform 21 and the top plate. Another set of first action units 4 and kettle units 3 are installed on the movable frame. A third action unit 6 is installed on the support platform 21, which is linked to the movable frame to drive its linear sliding. The third action unit 6 can also be implemented in various ways, such as a winch combined with a pulley and cable combination, or a screw and nut lifting combination. This solution uses a three-stage telescopic cylinder with a stroke of 0.8-2.2m, such as an SMC MXQ16-500A cylinder. The telescopic cylinder drives the movable frame to move up and down. Furthermore, as an extension of this solution, a laser ranging and positioning device can be installed on the movable frame or the support platform 21 to determine the position of the movable frame. This solution can use an STM32H743 as the main controller, connecting each unit via a CAN bus for control.
[0062] This structural design enhances the variety of movements in the fire pot performance. Furthermore, by combining the lifting and lowering motion of the third action unit 6, the vibration of the movable frame can be achieved through its starting and stopping movements, causing a large number of sparks to fall from the burning material in the container 31 of the corresponding fire pot unit 3, thus improving the visual appeal.
[0063] Based on the above implementation scheme, as a further optimization, this device can also be equipped with a vibration unit, which is set on a fixed frame and a movable frame. Then, the first actuation unit 4 is set on the vibration unit. The vibration unit triggers the first actuation unit 4 to vibrate, thereby causing the container 31 of the kettle unit 3 to vibrate, causing a large number of sparks to fall from the container 31, improving the visual appeal. The vibration unit can be implemented using a vibration motor or other mechanical vibration methods.
[0064] This solution provides an implementation of a vibration unit. Taking a fixed frame as an example, a vibration frame is provided, which is slidably connected to the fixed frame, with a spring between them. A sector-shaped cam is provided on the upper or lower side of the vibration frame, and the cam is connected to a motor. The rotation of the motor causes the protruding part of the cam to push the vibration frame away from the fixed frame. The spring stores force, and when vibration is needed, the cam continues to rotate to the break point of its sector-shaped area. Then, the vibration frame is no longer compressed, and as the spring returns to its original state, it drives the vibration frame to vibrate once.
[0065] Based on the above implementation scheme, the second action unit 5 can be set on a connecting platform, the central axis of which is rotatably connected to the first support structure 11. A cylinder is set between the first support structure 11 and the connecting platform, and the connecting platform is tilted by the cylinder, so that the second action unit 5 and the second bearing unit 2 on it can tilt synchronously, thereby enriching the actions of the fire pot performance.
