Abstract: A percussive sprinkler with adjustable discharge angle has a pedestal, adjusting ring, main body, percussion guide frame and sprinkler head driving rod. The percussive sprinkler is characterized by that, the height of the spacing for the driving rod retaining surface of the adjusting ring can be adjusted via an adjustor, such that the second end on the sprinkler head driving rod connected to the sprinkler head is abutted onto the driving rod retaining surface. When the main body of the percussive sprinkler is rotated, the sprinkler head driving rod will shift vertically along the circumferential path on the driving rod retaining surface, so the sprinkler head is driven to swing vertically with change of the discharge angle. In such a case, spray with different sprinkling distance can be generated by the sprinkler head, thus making up the shortcomings for more uniform sprinkling coverage with higher flexibility and applicability.

Abstract: There is described a portable water monitor for fire fighting, irrigating or other watering purposes. The water invention is of compact, stable, light-weight configuration. The device has a base unit which may be filled with water to increase the weight of the unit when deployed in the field. Compact plumbing is provided which permits the monitor nozzle to be rotated 360.degree. in the horizontal direction about a vertical axis swivel coupling and to be elevated and depressed in a ball and socket coupling. The ball and socket coupling additionally provides that the monitor nozzle may be offset relative to the swivel action coupling on the ball and socket coupling. This offset, which is actually the ability to point the nozzle away from the unit's vertical axis, creates a rotational force for the nozzle by harnessing a portion of the reaction force which acts through the center of the nozzle. The unit can be manually or remotely controlled.
