The screw rod 35 is fixed on the first vertical plate 7 through the connecting seat 42, and the screw rod 35 is arranged in the up-down direction. The sliding block 36 is threadedly connected with the screw rod 35. The driving piece 37 is in the shape of a sheet and is in the shape of L. One end of the driving piece 37 is fixedly connected with the sliding block 36, and the other end of the driving piece 37 is hingedly connected with the first driving connection part 20. When the stepping motor 34 drives the screw rod 35 to rotate, the sliding block 36 is raised or lowered, and the first driving connection part 20 is raised or lowered through the driving piece 37, so that the first ring-shaped part 19 is swung. The overall structure is simple, occupies small space and is stable. The two stepping motors 34 are controlled by the control module. According to a specific algorithm program, the nozzle 4 can realize rotation and swinging in any vertical plane. The swinging amplitude and the rotation amplitude are both vector control. The movement is accurate and convenient to control. In addition, the stepping motor 34 is in the shape of a straight line, and the nozzle 4 is acted on the first-dimensional swinging device and the second-dimensional swinging device through the two stepping motors 34 to realize two-dimensional movement. Compared with the traditional two-dimensional mechanism, there is no electric ring. The structure is more compact and reasonable.

[0061] In an optional technical solution of the embodiment, the first vertical plane and the second vertical plane are perpendicular. That is, the first vertical plate 7, the second vertical plate 8, the third vertical plate 13 and the fourth vertical plate 14 are arranged at equal intervals along the circumference of the second through hole 6. The common axis of the first rotating shaft 11 and the second rotating shaft 12 and the common axis of the third rotating shaft 40 and the fourth rotating shaft 41 are perpendicular to each other. The first guide rod 17, the second guide rod 18, the third guide rod 24 and the fourth guide rod 25 are arranged at equal intervals in the circumferential direction. The common axis of the rod part of the first universal joint 22 and the rod part of the second universal joint 23 and the common axis of the rod part of the third universal joint 29 and the rod part of the fourth universal joint 30 are perpendicular to each other and coplanar. That is, the nozzle 4 is controlled to move in two dimensions in the X-axis direction and the Y-axis direction in the horizontal plane. The stability of the movement of the nozzle 4 is improved, and the movement of the nozzle 4 is facilitated.

[0062] In an optional technical solution of the embodiment, the swinging angle of the first-dimensional swinging device is 90°, and / or the swinging angle of the second-dimensional swinging device is 90°. The stability of the movement of the nozzle 4 is improved, and damage caused by excessive movement of the nozzle 4 and the overall structure is avoided.

[0063] The embodiment provides a kind of fountain system, it includes the above-mentioned dry spray two-dimensional water scene numerical control nozzle, whereby, the technical advantages and effects reached by the fountain system include the technical advantages and effects reached by the above-mentioned dry spray two-dimensional water scene numerical control nozzle, here no longer repeat.

[0064] It should be noted here that the fountain system can be a musical fountain, and the control system thereof programs music through a program control system and a music control system, so that the fountain shapes are combined with music melodies and lights to produce varied water scenes, reflecting the music connotation and theme. The musical fountain is beautiful in sound, light, color and shape, and it can evoke people's emotions and provide artistic enjoyment.

[0065] The software of the musical fountain uses the physical waveform of a music file to divide it into several musical sections with an accuracy of ten milliseconds, and automatically identifies the basic emotional characteristics of the music, such as shock, longing, lyricism, joy, excitement, sadness, happiness and warmth, and converts them into control signals, which are output to the peripheral specific control units through a signal output card after synchronization processing, i.e., according to the water type configuration rules, the submerged pumps, electromagnetic valves, underwater color lights and frequency converters and other actuators are controlled to integrate visual and auditory experiences. The programming of the fountain music is to configure various water types according to the synaesthesia phenomenon, just like directing a dance, and in order to make the performance successful, the director needs to consider how the dancers perform the emotional charm of the music with their postures and movements.

[0066] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
