The pagoda body 2 has three layers which are arranged in sequence in the vertical direction and have a hierarchy.

[0040] The volume of each layer of the tower body 2 decreases from bottom to top, so that the center of gravity of the pagoda stage device is lower and the overall structure is more stable.

[0041] The tower base 1 is a concrete base, which is solid and has a large volume, and plays a role in bearing the weight and load of the pagoda stage beauty device, so that the pagoda stage beauty device can be placed more stably.

[0042] The surface of the tower body 2 is a steel structure layer, which has high strength, light weight, good overall rigidity and strong deformation ability, so that the pagoda stage equipment is more solid and has a longer service life.

[0043] The outer side surface of each layer of the tower body 2 is installed with an LED screen 16, and the LED screen 16 is installed with a naked-eye 3D device for obtaining a three-dimensional stereoscopic image of space and depth.

[0044] The naked-eye 3D device is a slit grating or a cylindrical lens or a backlight module (not shown in the figure) arranged in front of the LED screen 16. When the audience watches the LED screen 16, the visible images of the left eye and the right eye will be separated to present a 3D image, thus getting rid of the constraints of special glasses and improving the comfort of use.

[0045] Reference Figure 1 and Figure 2 The lower end of each tower body 2 is in a rectangular shape and a rectangular door frame 4 is opened on the side. A tower door 5 that closes the door frame 4 is rotatably connected to the tower body 2.

A suspension rope 9 is wound around the pulley 7, and a counterweight block 11 is fixed to the end of the suspension rope 9.

[0048] A slide rail 17 with a slot facing the counterweight 11 is provided on the inner side surface of the tower body 2 along the movement direction of the counterweight 11 . The slide rail 17 is located directly below the pulley 7 , and the counterweight 11 is slidably connected to the slide rail 17 .

[0049] A hanging ring 10 is fixed to the top of the counterweight 11 , and the hanging rope 9 is fixed on the hanging ring 10 .

[0050] A driving wheel 12 and a driven wheel 13 are rotatably connected to the sliding position of the inner side surface of the tower body 2 facing the counterweight block 11. The driving wheel 12 and the driven wheel 13 are arranged in the vertical direction. A traction chain 14 is wound around the driving wheel 12 and the driven wheel 13. The outer side surface of the traction chain 14 is fixedly connected to the side surface of the counterweight block 11. A motor 15 is fixed at the axial position of one of the driving wheels 12, and the motor 15 is fixedly installed on the inner bottom surface of the tower body 2.

[0051] The driving wheel 12, the driven wheel 13, the traction chain 14 and the motor 15 form a chain transmission mechanism for driving the counterweight 11 to move, so that the counterweight 11 drives the tower door 5 to turn outward to an open state or close when moving.

[0052] Reference Figure 5 A transmission rod 22 is fixed to the axial position of two adjacent driving wheels 12 inside each layer of the tower body 2. One end of the transmission rod 22 is fixed to the driving wheel 12, and the other end is fixed to the inner side of the tower body 2. The two transmission rods 22 at adjacent positions are vertically arranged and connected by a first bevel gear 20 and a second bevel gear 21. The first bevel gear 20 and the second bevel gear 21 are vertically meshed, and the first bevel gear 20 and the second bevel gear 21 are fixedly connected to the transmission rods 22 at adjacent positions, respectively.

[0053] Reference Figure 6 A water distribution tank 233 is provided at the center of the inner bottom of each layer of the tower body 2. The water distribution tank 233 is in a rectangular shape. The four sides of the water distribution tank 233 are installed with nozzles 231 facing the door frame 4. The water distribution tanks 233 in each layer of the tower body 2 are connected through pipes 232. A waterproof water pump (not shown in the figure) is fixed in a hollow position at the bottom of the tower base 1. The input end of the water pump is connected to the water pool, and the output end of the water pump is connected to the inlet of the pipe 232.

[0054] The spray head 231 , the pipe 232 , the water pump and the water distribution tank 233 constitute a water spraying device for spraying water out of the tower body 2 through the door frame 4 .

[0055] Each layer of the tower body 2 is equipped with a lighting device 18 that irradiates light through the door frame 4 to the outside of the tower body 2. The lighting device 18 is suspended and fixed on the inner top of the tower body 2 and is located directly above the water distribution tank 233. The lighting device 18 is a laser light or a moving head light.

[0056] Laser lights include solid-state lasers. When in use, the crystal rod generates a laser beam, which is frequency-converted through control software to form visible green light. The computer controls the galvanometer to deflect at high speed, thus forming beautiful text or graphics. The light beam is projected into the distance and can swing up, down, left, and right. It can be seen within a radius of several kilometers and is very dazzling.

[0057] Moving head lights are light bulb-style pattern lights that emit light beams to form light spots and pattern effects. By matching different colors and patterns, they form soft and gorgeous scenes, showing soft and intellectual art. At the same time, they are stable and reliable, have excellent lighting effects, accurate positioning, good heat dissipation, and the lamp body and material structure meet the requirements of ergonomics.

[0058] A flame-spraying device 19 is installed inside each layer of the tower body 2 to spray fire out of the tower body 2 through the door frame 4. The flame-spraying device 19 is fixedly installed at the inner bottom of the tower body 2, and the water distribution tank 233 is fixedly installed at the top position of the flame-spraying device 19.

[0059] The flamethrower 19 comprises a flamethrower (not shown in the figure) and a pair of electronic ignition fuses (not shown in the figure). The flamethrower is a gas box integrated palm-held flamethrower with a small size and light weight. After locking the aiming position, the flamethrower regulates the pressure and changes the flow of the gas to spray out of the muzzle. The special oil stored in the butane gas tank is ignited to form a flame tongue when passing through the electronic igniter at the front end of the flamethrower, thereby realizing the flame spraying state.

[0060] Reference Figure 7 A pressure sensor (not shown in the figure) is provided in the tower body 2 for converting the pressure value of the water spraying equipment into an electrical signal in real time and outputting the signal. The model of the pressure sensor is PT124B-2506.

[0061] The output end of the pressure sensor is electrically connected to a microcontroller, and the model of the microcontroller is MCS-51.

[0062] The output end of the microcontroller is electrically connected to the motor 15 . When the pressure sensor inputs an electrical signal to the microcontroller, the microcontroller controls the motor 15 to start.

[0063] The lighting device 18 is electrically connected to the output terminal of the microcontroller. When the pressure sensor inputs an electrical signal to the microcontroller, the microcontroller controls the lighting device 18 to emit light.

[0064] The flame spraying device 19 is electrically connected to the output terminal of the microcontroller. When the pressure sensor inputs an electrical signal to the microcontroller, the microcontroller controls the flame spraying device 19 to spray flames.

[0065] The implementation principle of this embodiment is: the pressure sensor monitors the pressure value in the pipeline 232 in real time.

[0066] When the water pump is started, the water is pumped out into the water distribution tank 233 through the pipe 232 and sprayed out to the outside of the tower body 2 through the nozzle 231 .

[0067] At this time, the pressure sensor converts the water pressure value in the pipeline 232 into an electrical signal and inputs it into the microcontroller, and the output end of the microcontroller outputs control signals to the motor 15, the flamethrower 19 and the lighting device 18 respectively.

[0068] The motor 15 is started, driving the driving wheel 12 to rotate, and the driving wheel 12 drives the traction chain 14 connected thereto to transmit, and the traction chain 14 drives the driven wheel 13 to rotate, so that the traction chain 14 drives the counterweight 11 fixed thereto to slide along the slide rail 17, applies a force to the suspension rope 9, pulls the suspension rope 9, and the suspension rope 9 is unfolded. The suspension rope 9 drives the pulley 7 to rotate, and the pulley 7 drives the rotating shaft 6 to rotate, thereby driving the tower door 5 to rotate and turn outward to an open state. While the driving wheel 12 rotates, the transmission rod 22 fixed thereto rotates, and the transmission rod 22 drives the first bevel gear 20 fixed thereto to rotate, and the first bevel gear 20 drives the second bevel gear 21 meshing therewith to rotate, and the second bevel gear 21 drives the transmission rod 22 fixed thereto to rotate, so as to achieve the effect of driving the driving wheel 12 in each layer of the tower body 2 to rotate synchronously in turn, so that the tower door 5 in each layer of the tower body 2 of the self-performance pagoda stage beauty device is opened at the same time.

[0069] The nozzle 231 sprays water through the door frame 4 to the outside of the tower body 2, thereby achieving a water spraying effect.

[0070] The flame-spraying device 19 is started, and the fire is sprayed out through the door frame 4 to the outside of the tower body 2, thereby achieving the effect of flame-spraying.

[0071] The lighting device 18 is started, so that the light beam is emitted to the distance through the door frame 4 and can swing up and down and left and right, or, a light beam formed by the combination of different colors and patterns is irradiated to the outside of the tower body 2 through the door frame 4 to achieve the lighting effect.

[0072] Turn off the water pump to stop the water spraying device from spraying water. At this time, the pressure sensor stops inputting electrical signals to the microcontroller, and the microcontroller outputs control signals to the motor 15, the flame spraying device 19 and the lighting device 18 respectively.

[0073] The motor 15 drives the counterweight 11 to move upward. At this time, the lifting rope 9 is in a relaxed state. Under the action of the torsion spring 8, the pulley 7 rotates in the opposite direction to return to its original position, driving the rotating shaft 6 to rotate in the opposite direction. At the same time, the lifting rope 9 is wound around the pulley 7, and then the rotating shaft 6 drives the tower door 5 to rotate until the door frame 4 is closed and stops, and the motor 15 is turned off.

[0074] At the same time, turn off the flamethrower 19 and the lighting equipment 18. At this time, the LED screen 16 and the naked-eye 3D device can be turned on according to the actual situation, and the video can be played on the LED screen 16 to present realistic three-dimensional images to the audience, thereby enhancing the viewing experience of the pagoda stage beauty device and diversifying the functions of the pagoda stage beauty device.

[0075] Furthermore, when the self-performance pagoda stage beauty device sprays water, the tower doors 5 on the four sides of each layer of the tower body 2 are opened, so that the nozzles 231 in the tower body 2 spray water through the door frame 4 to the outside of the tower body 2, that is, the device itself is dynamic, has a self-performance effect, and is personalized in design; at the same time, the lighting equipment 18 emits light, the fire-spraying equipment 19 sprays fire, and the control is intelligent, so that the tower door 5, the lighting equipment 18, the fire-spraying equipment 19 and the water-spraying equipment work together to present a beautiful visual feast.

[0076] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
