Abstract

PURPOSE: To realize a clear intermittent waterspout with a simple structure by providing a moving mechanism which moves a wedge member for deflecting a waterspout column based on a cutting mechanism between a position for deflecting the waterspout column at cutting time and a position for making it run out to the outside of a container at generating the waterspout. CONSTITUTION: In an intermittent waterspout apparatus 5, a pressurized water from a pump is run into a buffer in a container 11 in the axial direction and while it changes the flow direction in the right angles direction, it runs into the container 11 and the flow is adjusted to a flow in the axial direction by means of a porous member to form a waterspout column A from an jetting outlet 12a. When the cutting timing for the waterspout column A comes, electric power is fed in a solenoid 31 and an output shaft 31a is forwarded to rotate a wedge member 19 to a position for cutting time expressed by a two points chain line. The waterspout column A is cut thereby to be separated left and right and they are deflected to the outside in the radial direction of a spouting pipe 22 and each separated waterspouting column collides to the top lid 25 and falls down and is discharged outside from a discharging hole 20. As the result, the waterspout column A is cut to realize a condition where a waterspout rod with a short length flys in the air.
