Most of the existing works of art are static works, and they cannot express artistic connotations through movement. In addition, most of the existing works of art are relatively single in artistic expression, and do not use a variety of artistic expressions. There are often designs containing lotus shapes in life, which have beautiful meanings. Traditional lotus shapes are mostly fixed shapes, and dynamic ones are relatively rare. There is a Ming Dynasty "Flowering Buddha" manual machine in Luohou Temple, Wutai Mountain, Shanxi Province. There is a red wooden lotus more than three meters high in the middle of the rotating disc. The monks in the basement push it by hand, and the wooden disc above rotates through mechanical transmission. The eight-petal lotus automatically opens under the action of gravity, slowly opens, and rotates clockwise. There are also petal opening and closing mechanisms on the market. Chinese patent 202021783586.0 discloses an artwork petal opening and closing mechanism, which uses a motor shaft as a screw shaft, and a sensor locator is arranged around the central axis on the base, and a rotatable blade sensor wheel and petals are correspondingly arranged.

[0026] The DC motor 5 is arranged in the base 1, and the output end of the DC motor 5 is connected to the vertical shaft 3. The upper part of the vertical shaft 3 is fixedly connected to the turntable 2. The turntable 2 is made of non-ferrous metal and is a disk-shaped body with an opening facing downward.

[0027] A plurality of lotus petals 4 are evenly arranged along the circumferential direction on the upper end surface of the turntable 2. In the present embodiment, the number of lotus petals 4 is twelve, six of which are inner petals and six are outer petals. The inner petals and the outer petals are arranged at intervals from each other. The upper and middle parts of the lotus petals 4 are made of polymer materials and wood materials, and the lower part is made of non-ferrous metals. The lower part of the lotus petals 4 is provided with a bend to form a convex arc surface.

Two push rods 10 are symmetrically arranged at the lower end of the circular ring 9. A bottom plate 11 is arranged at the lower end of the push rod 10. The bottom plate 11 is fixedly connected to the outer wall of the vertical shaft 3. A spring 12 is arranged between the bottom plate 11 and the circular ring 9. The speed of the push rod 10 is 4-80 mm per second. The push rod 10 controls the displacement of the circular ring 9, thereby linking the pull rod 8 to drive the lotus petal 4 to open and close.

[0029] The control circuit includes a three-phase rectifier bridge, a phase-changing switch K2, a speed regulator TS, a battery E0, three-phase coils Wa, Wb, Wc, a carbon brush 16, and a plurality of permanent magnets 13. In this embodiment, the number of permanent magnets 13 is four. Figure 3 As shown, four permanent magnets 13 are evenly arranged at the lower end of the annular plate 14, the annular plate 14 is fixedly connected to the lower part of the vertical shaft 3, the magnetic poles of adjacent permanent magnets 13 are arranged oppositely, the permanent magnets 13 rotate with the vertical shaft 3, and are used to cut the coil 15 during the rotation process. Figure 4 As shown, the three-phase coils Wa, Wb, and Wc are six coils 15 connected in pairs with each other as one phase. Specifically, the three-phase coil Wa is connected by coils Wa1 and Wa2, the three-phase coil Wb is connected by coils Wb1 and Wb2, and the three-phase coil Wc is connected by coils Wc1 and Wc2. The three-phase coils Wa, Wb, and Wc are fixedly arranged on the upper end surface of the base 1 and are arranged opposite to the four permanent magnets 13. When the permanent magnets 13 rotate with the vertical shaft 3, the three-phase coils Wa, Wb, and Wc are used to generate an induced voltage to charge the battery E0.

When the speed of the vertical shaft 3 exceeds 50 rpm, the switch K1 is disconnected, and the voltage values ​​of the three-phase coils Wa, Wb, Wc and the AC capacitors C1, C2, and C3 are nearly equal. The three-phase coils Wa, Wb, and Wc generate induced electromotive force under the action of the rotating magnetic energy, which increases the output voltage of the rectifier assembly. The voltage value of the battery E0 will slowly increase to power the DC motor D. When the turntable 2 rotates clockwise, the push rod 10 moves downward and the lotus petals 4 open. When the turntable 2 rotates counterclockwise, the push rod 10 moves upward and the lotus petals 4 close.
