PROBLEM TO BE SOLVED: To provide a water cannon device in which the movement by a large adjustment operation is converted into the movement of changing a small collision angle of a deflector, and thereby a high accuracy of adjustment can be obtained and a durable structure of an adjusting mechanism is ensured.SOLUTION: A deflector 32 is provided in a movable case 36 pivotally supported around a horizontal circumference to a base where a water pipe 28 side of a water discharge nozzle is fixed and installed, and turnably pivoted in the vertical direction by a first fulcrum shaft 38 of the fixed side, and thereby a deflector 32 is supported in front of the water discharge nozzle. A collision angle adjustment mechanism is configured such that one end of a telescopic rod mechanism 46 is turnably pivoted to a fixation case 34 as a second fulcrum shaft 40, and the other end of the telescopic rod mechanism 46 is turnably pivoted to a movable case 36 as a third fulcrum shaft 42. A telescopic rod mechanism 48 is telescopically moved in an axial direction by the rotating operation around the shaft of a connecting rod member 48, and the spacing between the second fulcrum shaft 40 and the third fulcrum shaft 42 is changed. The movable case 36 is turned around the first fulcrum shaft 38 and a jet collision angle to the deflector 32 is adjusted. |
