JPH0810668A - Nozzle elevation-variable type automatically controlled waterspout - Google Patents

Abstract

PURPOSE:To form a complicated waterspout shape with a small number of nozzles by connecting a nozzle with the downstream side of a control valve inserted in a water supply pipe through a flexible pipe joint and inserting through this upper part into an opening of a crossing part of a stereo-cross- shaped elevation-variable mechanism. CONSTITUTION:When a plurality of servo-driven motors 4 and 4 are rotated respectively in X and Y directions, a plurality of curved belt sheets in an elevation-variable mechanism are rotated respectively in alpha and beta directions. As the result, the base part of an elevation-variable nozzle 12 is rotated along a nozzle supporting stage 10. In this time, as the intermediate part of the elevation-variable nozzle 12 is loosely restricted in a long hole 8 of each curved belt sheet, the ceutral line of the elevation-variable nozzle 12 points to a specified elevation. By the way, variation of the elevation can be done by either successive rotation or simultaneous rotation of the servo-driven motors 4 and 4 and for the simultaneous rotation, the cross space of the elevation-variable mechanism 5 may be rotatively moved in the direction r. In addition, rotation of each servo-driven motor 4 and 4 is controlled by means of a computor.
