Description

SPRINKLER ASSEMBLY WITH STABILIZING BASE UNIT AND
SYSTEM
TECHNICAL FIELD
[001] The present disclosure described herein, in general, relates to irrigation systems, more particularly to a sprinkler assembly with a unit connected to a vertical riser pipe and/or a rotating sprinkler head for stabilization.
BACKGROUND
[002] A conventional sprinkler assembly consists of sprinkler head, sprinkler holding adaptor, a flexible plastic riser tube/vertical riser pipe, a male take-off adaptor connected to the flexible plastic riser tube, and a female take-off adaptor suitable to adopt the male adaptor. Further the female adaptor is securely fitted on a flexible plastic hose. The Sprinkler head is positioned above the ground at a specified height using a metal spike support. One end of metal spike support is connected to sprinkler holding adaptor and the other end inserted in the ground at a longer length to stabilise the assembly. Further female take-off adaptor is inserted into plastic hose and the male take-off adaptor which is connected to flexible plastic tube is connected to each other to form a watertight joint. The conventional system enables easy detachment and attachment of the sprinkler unit with hose pipe. However, the conventional system requires multiple components to be attached or connected to each other to form the complete assembly.
[003] The other limitation of the conventional sprinkler system is attaching the sprinkler head to a metal spike through sprinkler holding adaptor. Since, the metal spikes are inserted in the ground surface, over a period the surface of the soil may get loose due to the torque and vibrations generated due to rotation of the sprinkler head and wetness of the soil, thus resulting in tilting or falling of the sprinkler and damaging of the crops. Further the metal spikes corrode over long period of use due humidity during irrigation and salinity of soil and water. [004] Various systems were developed to overcome certain limitations of the conventional sprinkler. In some systems, the sprinkler head is mounted on a rigid riser pipe and other end of the rigid riser pipe is connected to a saddle. The saddle is used for stabilization on the ground surface. Saddle is connected to the hose pipe through multiple connectors. However, the said sprinkler requires breaking the hose pipe into several pieces for the connections. The pieces of the hose pipe are then connected or disconnected to the saddle that involves time and efforts. Further the said system is costlier than the conventional systems described earlier as said sprinkler involves additional fittings.
[005] In some other systems, the system comprises a stabilized base unit and a sprinkler head mounted on the stabilized base unit. The system was aimed to provide a separation of the stabilising unit and the sprinkler head. However, said system has a limitation that only one sprinkler head unit can be attached to the stabilising unit and the system does not allow the installation of multiple such sprinkler devices on a single hose pipe. In other words, such systems require a dedicated hose pipe for each sprinkler device.
SUMMARY
[006] This summary is provided to introduce concepts related to a sprinkler system and the concepts are further described below in the detailed description. This summary is not intended to identify essential features of the claimed subject matter nor is it intended for use in determining or limiting the scope of the claimed subject matter.
[007] In an aspect of the present disclosure, a sprinkler assembly for use with a hose pipe is disclosed. The sprinkler assembly comprises a base unit having a first end and a second end, and a sprinkler section coupled with the base unit at the first end.

The sprinkler assembly may comprise a base unit, a vertical rigid riser pipe and a sprinkler head. The sprinkler assembly may be connected to a hose pipe through a female take-off adaptor. Further in another embodiment, the present disclosure discloses a sprinkler system with a plurality of sprinkler assemblies mounted on a single fluid carrying hose pipe, across the length of the hose pipe at a pre-determined distance. Further in accordance with the present disclosure, the sprinkler assembly may comprise a male take-off adaptor, wherein the male take-off adaptor may be an integral part of the base unit. The base unit may be connected to one end of the vertical rigid riser pipe through a mating adaptor, and the other end to the hose pipe by snap-on mating connection with the female take-off adaptor which is securely mounted on the hose pipe. The female take-off adaptor is designed to remain in close vicinity of the hose pipe so that it will not be a hindrance or will not get entangled while coiling or recoiling the hose pipe.
