An aimable sprinkler is disclosed. The sprinkler can be mounting on an end of a traveling sprinkler system that moves in a linear direction or one that rotates about a center pivot tower. The sprinkler can include a base for connecting to the traveling sprinkler system and a turret coupled to the base so as to move in both yaw and pitch directions relative to the base. The sprinkler aims at discrete points within an irrigation area to achieve an even distribution of water.

The present application belongs to fluid control equipment, in particular, relates to directional controlling mechanism of fluidic sprinkler, comprising a rear reversing mechanism, a front reversing mechanism and a signal stream switching mechanism. A limiting shift rod of the rear mechanism rotate around a locating rod as the center after touching a limiting ring, then realize the reversing of the limiting shift rod. The reverse action of the limiting rod will finally lead a reversing arm to rotate by way of driving a reversing locating block, a rear reversing rod and a front reversing rod to rotate. The rear reversing mechanism, the front reversing mechanism and the signal stream switching mechanism act together, so as to switch a left-side signal stream nozzle and a right-side stream nozzle of a fluidic sprinkler, and bring about the reversing of the rotation direction of the fluidic sprinkler. Directional controlling mechanism of fluidic sprinkler is in a stepping state respectively in the clockwise and the counter clockwise working modes, so that the impact force on a rotary body is small, critical components tend to have a longer working life, an intermediate position does not exist during the reversing of the sprinkler, and the switching of the sprinkler is stable and reliable.

A water sprinkler includes a housing and an ejection head. An impeller is assembled in the housing, pushed by water, and connected to a cam. A water-hit target is pivoted with the housing via a compression spring, and an impacted portion of the water-hit target is extending outside of the housing. The water-hit target repeatedly impacts the housing because of the pivoting motion caused by the pushing of water flow and by the pulling of the compression spring, so that the housing is pivoted to change the ejection direction of the ejection head. A water baffling cover is pivoted with the housing. A abutted member is assembled on the water baffling cover and abutted against the cam. The cam can push the abutted member to drive the pivoting motion of the water baffling cover, so that the water baffling cover shields the ejection head by different extents.

A cable driven irrigation device has a frame that acts as a manifold to supply a sprinkler head and a separate spray nozzle. The frame is supplied with an externally triggered latching valve. The valve is held in the open position by a spring and has an internal flap that enters the flow of water through the valve when the external trigger is moved. The water flow moves the flap to the closed position and holds it there until the water pressure is removed. The spray nozzle dispenses water onto an exposed turbine which drives a gearbox. The gearbox is coupled to a spool which can wind up a cord. The spool being wound is what pulls the sprinkler along. A knot near the end of the cord engages the external trigger to stop the flow of water into the frame.

A rotating sprinkler is configured with only three components without need of any other manufactured component. The three components are constituted by a base component connected to a water source, a rotating head component from which a water stream is emitted which is rotatably mounted on an element of the base component, and a gravitating hammer component pivotally mounted on the head component that causes intermittent rotary motion of the head component about a vertical rotation axis by intermittently engaging the emitted stream and providing in response a reaction force. The hammer component is configured to intercept the emitted water stream within an interior space between a deflecting surface and a ramping surface when downwardly pivoted and to urge the intercepted water stream to flow upwardly along the ramped surface and to impinge upon the deflecting surface, causing the hammer component to pivot upwardly prior to being gravitated.

A rotating sprinkler includes a housing and a movable core. The core can assume retracted and extended states relative to the housing and incudes a cover, an impact member and a stream deflector. In the extended state, both the cover and the impact member can pivot between pivoted and non-pivoted states about a hinge defining an axis H generally orthogonal to axis X and the stream deflector is fixed against rotation about the hinge.

An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.

Disclosed is an adjustable and portable fire protection sprinkler system. The device consists of a sprinkler head mounted on an adjustable height center pole connected to adjustable legs, forming a foldable tripod-like configuration. The legs and center pole have inner and outer tubes arranged for telescopic movement relative to each other, for adjusting the height of the pole and the lengths of the legs. The sprinkler head is connected to a rubber hose which is threaded through the top of the center pole and connected to a water source at the bottom. The tube stretches and retracts inside the pole corresponding to the pole height. A collar around the pole connected to the legs, wherein the legs connected to the end of the pole by metal strips. This allows for sliding up and down; increasing or decreasing the triangular base parameter. The base is also defined by the length of the legs and is adjusted to maintain the tripod stability.

A rewinding waterwheel includes a secondary body, a main body and guide members. The main body includes a rewinding waterwheel frame, a hub ring shaft and a water pipe wound around the hub ring shaft. The hub ring shaft is installed onto the rewinding waterwheel frame and rotatable. The secondary body includes a waterwheel frame and a sprinkler head mounted onto the waterwheel frame. The water pipe is fixed and communicated to the sprinkler head; the guide member is installed on the ground; the water pipe is in a rolling contact with the outer circumferential surface of the guide member. In a water spray method of the rewinding waterwheel, a traveling path is designed to achieve automatic lawn irrigation by the guide member in contact with the water pipe and to change the irrigation speed by the transmission gearbox to control water volume and save energy.
