A protection device for an irrigation system having at least one water line and at least one irrigation sprinkler head, the protection device comprising a protector body having a wall defining an interior cavity, a top rim, and a bottom rim with at least two groove pairs, wherein a first groove pair has a first groove profile, and a second groove pair has a second groove profile, the second groove profile being different from the first groove profile, an adapter cap having an outer rim surface, an annular ledge extending inward from the outer rim surface, a bottom surface, and a top surface, the adapter cap detachably connected to the protector body, a collar insert having an outer edge, an inner edge defining a center aperture, and a lower surface, the collar insert detachably connected to the adapter cap, and wherein the protector body is selectively ridingly engaged between a first riding engagement with the first pair of grooves and a second riding engagement with the second pair of grooves on at least one water line.

A rotary sprinkler riser extension kit is disclosed for use with a rotary sprinkler. The kit includes an external riser extension having an upper end and lower end, and defining a channel extending through the upper end and lower end. The channel is configured to accommodate the stem of the rotary sprinkler, the upper end is configured to attach to the cap of the rotary sprinkler, and the lower end is configured to attach to the enclosure of the rotary sprinkler. The kit also includes an internal riser extension having a height substantially equal to total length of the external riser extension, a width less than inner width of the enclosure of the rotary sprinkler, means for attaching to the geared lower end of the stem, a lower gear configured to rotate the rotary sprinkler, and means to raise the stem and channel water thereto in response to water pressure at an inlet to the enclosure.

The invention relates to a device (10) for providing mist to a surrounding environment, the device (10) comprising a housing unit (12) having an inlet opening (18), an outlet opening (20), and a chamber (22) extending between the inlet opening (18) and the outlet opening (20) along a central axis (24); a nozzle unit (14) including at least one orifice (26); wherein the nozzle unit (14) is arranged in the chamber (22), the nozzle unit (14) being slidable along the central axis (24) between a closing position, in which the nozzle unit (14) closes the outlet opening (20), and an opening position, in which the at least one orifice (26) connects the chamber (22) to the surrounding environment in fluid communication; wherein the nozzle unit (14) transfers from the closing position to the opening position if a fluid pressure at the inlet opening (18) exceeds a predefined threshold; wherein the nozzle unit (14) comprises a deflector part (28) for deflecting fluid in the opening position and for closing the outlet opening (20) in the closing position, wherein the at least one orifice (26) is arranged offset to the central axis (24) between the inlet opening (18) and the deflector part (28); wherein the at least one orifice (26) is configured to guide fluid flowing through the at least one orifice (26) and to lead the fluid towards the deflector part (28). The invention provides an improved device (10) for providing mist to a surrounding environment, which reduces the required amount of fluid and increases the efficiency of the fluid distribution.

A sprinkler clamp assembly for servicing sprinkler heads includes a clamp that has a pair of curved jaws. Each of the curved jaws curves toward each other such that the pair of curved jaws defines a circle when the clamp is biased into a closed position. In this way the curved jaws can encircle a stem of a sprinkler head. Each of the curved jaws rests against a housing of the sprinkler head when the curved jaws are positioned around the stem of the sprinkler head. A head of the sprinkler head abuts each of the curved jaws when the stem retracts into the housing to retain the head in an exposed position for servicing.

A nozzle is provided having a low precipitation rate and uniform fluid distribution to a desired arcuate span of coverage. The nozzle has an inflow port having a shape corresponding to the desired arc of coverage and a size for effecting a low precipitation rate. The nozzle also has a deflector surface with a water distribution profile including ribs for subdividing the fluid into multiple sets of fluid streams. There are at least two fluid streams for distant and close-in irrigation to provide relatively uniform distribution and coverage. The nozzle may be a unitary, one-piece, molded nozzle body including a mounting portion, an inflow port, and a deflector portion.

A sprinkler head for attaching to a stem of a sprinkler, the sprinkler head having a round or polygonal shaped perimeter and comprising a directional nozzle array on the perimeter of the sprinkler head, the directional nozzle array comprises a single nozzle or a stack of nozzles each nozzle having an orifice facing a specific radial direction; the directional nozzle array being in fluid connection with a conduit through the stem for providing irrigation in the radial direction; wherein the directional nozzle array is provided with a dedicated regulator independently configurable by the user for regulating water flow in the specific radial direction over a range from zero when fully closed to a maximum range when fully open.

An anti run-over (ARO) sprinkler device including a housing, piston region, body region, piston, first cap, first seal, primary spring, second cap, second seal, secondary spring and water inlet. The device operates to prevent damage to the device when unintentional force is applied thereto. The device includes a secondary spring which contracts when unintentional force is applied to the device to prevent damage to the device. The secondary spring is configured to operate in either a contracted state where coils of the secondary spring are compressed together thereby causing the piston to pull downwards into the second cavity of the housing when pressure is applied to the second cavity or in a retracted state where the coils of the secondary spring are extended away from one another thereby causing the piston to push outward from the second cavity and into the first cavity when the pressure applied to the second cavity ceases.

Embodiments of the disclosure relate to automated water sprinkler systems, and more particularly to programmable electronically controlled sprinkler systems which are controllable to affect sprinkler direction and time of watering over a defined coverage pattern. The particular improvements disclosed herein relate to location awareness of the system based on physical location of the unit relative to one or more base platforms, as well as gesture/motion control of the unit for manual operation through the use of an on-board accelerometer.
