[0051] The working principle of the water dancing robot intelligent numerical control device of the present invention is as follows:

[0052] The controller can control the movement of the first motor 61 or the second motor 71 individually according to the fountain effect requirements, or can control the movement of both motors together. When both motors rotate, there is a coupling relationship.

[0053] Specifically, the main motor (i.e., the first motor 61) drives the first driving gear 62 to move, performs a 1:12 deceleration movement, and then transmits in sequence through the first driving gear 62, the first driven gear 63, the first driving gear 66, the second driven gear 64, the second driving gear 67 and the third driven gear 65, thereby driving the main rotating shaft (i.e., the hollow shaft 50) to rotate.

[0054] The auxiliary motor (i.e., the second motor 71) drives the second driving gear 721 to move, and then transmits the power in sequence through the fourth driven gear 722, the third driving gear 726, the fifth driven gear 723 and the sixth driven gear 724, thereby driving the auxiliary rotating shaft 725 to rotate. Then, the auxiliary rotating shaft 725 is transmitted through the first bevel gear 731, the second bevel gear 732, the bevel gear rotating shaft 733 and the flow stabilizer 734, thereby driving the nozzle to rotate 360°.

[0055] The intelligent numerical control device of the water dance robot of the present invention rotates as a whole through one motor driving the device, and another motor drives the nozzle to rotate 360 ​​degrees. When the two motors are driven simultaneously, the movements are coupled. Therefore, the direction of the water spraying action can be freely adjusted, thereby achieving the performance effects of various water scenes and improving the overall beauty of the landscape water body.

[0056] The water flow direction of the equipment of the present invention is as follows:

[0057] Water enters the water inlet pipe 41 of the main fixing seat 40 through the first opening of the lower cover shell 31, then enters the hollow shaft 50 through the water inlet hole 501 of the hollow shaft 50, goes all the way upward to reach the water delivery channel of the nozzle chamber, and after coming out from the water outlet 201 of the nozzle chamber 20, passes through the steady flow rotating shaft to reach the nozzle, and is then sprayed out to achieve various movements required for the water performance.

[0058] It should be noted that in order to prevent water leakage, each bearing is provided with a sealing ring for waterproofing, and the connections are connected with a retaining spring to prevent movement.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
