The external device 150 provides the water droplet molding information to the 3D water curtain device 100. The external device 150 includes a mobile phone, a smart phone, a smart watch, a tablet, a PC, a notebook, a mobile robot, a handheld device, a wearable device, and the like.

Figure 2 (a) shows a water tank structure formed of a double pipe used in the three-dimensional water curtain apparatus as an embodiment of the present invention. The water tank can be manufactured in the shape of a cuboid and fixed to the ceiling. Figure 2 (b) to (f) shows an example of the double pipe used in the three-dimensional water curtain apparatus as a preferred embodiment of the present invention. Hereinafter, a description will be given with reference to FIGS. 1 and 2 (a) to (f).

In addition, the 3D water curtain device 100 may project the 3D sculpture image displayed on the display of the external device 150 to the water droplet molding unit 140 through the projector 160. The projector 160 may be used to project an image texture onto the water droplet formation surface formed by the water drop molding unit 140 so that the viewer on the opposite side may recognize the transmitted image. Different colors can project images of different colors. The image descends sequentially when the water drop stereoscopic modeling descends.

As a preferred embodiment of the present invention, the three-dimensional water curtain device 100 is implemented in a double pipe as in the embodiment shown in Figure 2 (c) to (f). The double pipe is composed of an inner pipe 231 and an outer pipe 230. The outer pipe 230 encloses the inner pipe 231, and L solenoid valves 232 are attached to the outer side of the outer pipe 230 in the longitudinal direction, and the nozzles 233 are provided at each of the L soloade valves. It is produced in attached form. The double pipe is made so that at least L droplets are generated by creating L nozzle holes in the outer pipe 230 as shown in FIG.

When water flows directly into the L nozzle holes formed in the outer pipe, the possibility of variation in the hydraulic pressure applied to the nozzle is increased depending on the position of the L nozzles arranged along the pipe. In a preferred embodiment of the present invention, in order to equalize the hydraulic pressure applied to each nozzle, after flowing water to the inner pipe 231 as shown in Figure 2 (f), the water inside the internal pipe 231 generated Water flows to the outer pipe 230 through many holes 231a, 231b, and 231c. As a result, a constant hydraulic pressure is applied to each nozzle used in the three-dimensional water curtain apparatus.

As a preferred embodiment of the present invention, the three-dimensional water curtain device 110 is arranged M in the horizontal direction as shown in Figure 2 (a) to (b).

For example, the horizontal resolution L * M can be set to 45 * 45, the spacing between the center of the droplet can be implemented in 4cm. The vertical resolution cannot be set arbitrarily because of the acceleration of gravity, and the maximum resolution considering the influence of gravity is calculated and set. For example, 18 water droplets are generated at a 2 meter vertical section. .

The controller 120 may control the opening and closing of the solenoid valve to control the timing of generating water droplets at each nozzle. Various methods may be implemented for controlling each nozzle in the controller 120. The control unit 120 calculates generation time information of each water drop constituting the three-dimensional water drop molding or reads from the file and transmits a generation signal of each water drop to a valve attached to the double pipe. The controller 120 determines and controls the time point at which the water droplets are generated in each nozzle such that the water droplets generated in the L * M nozzles maintain equal intervals in a specific vertical section.

The controller 120 may control the opening and closing of the L solenoid valves disposed in the respective double pipes. The controller 120 may control the nozzle in a double pipe unit. The control unit 120 may control by synchronizing the double pipe of L * M units. The controller 120 may also separately control each of the L * M nozzles.

As a preferred embodiment of the present invention, the control unit 120 reads the generation time information of the respective droplets constituting the digital water drop three-dimensional molding to configure the droplet generation unit 140 or the water drop stereoscopic unit 140 to generate the generation signal of each droplet It transmits to the double pipe to control the water droplets are generated. The generation signal of the droplets may indicate a signal for opening and closing a valve for generating the corresponding droplet and an opening period.
