Definitions
- the invention relates to a sprinkler.
- Sprinklers as garden irrigation devices typically have a sprinkler head forming a water outlet with a nozzle arrangement which is pivotable about a pivot axis relative to a body containing a water inlet.
- the pivot axis is typically vertical, horizontally aligned with square sprinklers.
- the swiveling of the sprinkler head is usually carried out via a sprinkler gear, which is driven by a turbine wheel.
- the turbine is reversibly rotatable in two opposite directions of rotation, for which the drive water flow two separate supply ducts and a switching means arranged upstream of the channels, which switchably connects one of the supply ducts to the water inlet, are provided.
- a water flow from the water inlet to the water outlet flows at least partially as a drive water flow across the turbine and typically as a bypass water flow via a spring-loaded valve, the bypass water flow being mostly greater than the drive water flow.
- Such a sprinkler with a turbine driven by a turbine is known from EP 0 489 679 A1.
- the individual turbine blades form pocket-shaped cavities which open with narrow radial slots to a cavity surrounded by the ring of the turbine blades.
- Two supply channels lead with round, parallel to the turbine axis first sections of a switching device upwards and open into narrower second sections, which arcuately surround the turbine in opposite angular segments. Of the second sections each have a plurality of narrowing nozzle channels angled away in the direction of the turbine.
- a problem with such sprinklers is that, due to the system, the force exerted on the turbine by the drive water flow is small and therefore there is a risk that the turbine will not start up during a restart or one of the numerous switchover operations. Since the sprinklers for garden irrigation in the production should be inexpensive, the design options are limited.
- the object of the present invention is to provide a sprinkler with a turbine gearbox driven by a turbine, with which the starting behavior of the turbine is further improved with little effort.
- the measures according to the invention significantly improve the flow properties of the water path through which the drive water flow flows.
- the inventors have recognized that by the described measures a reduction of vortices can be achieved and thereby the energy losses of the drive water flow can be greatly reduced, so that a higher proportion of energy remains for acting on the turbine forces and causes a higher starting torque can be.
- a first significant improvement results from redesigning a deflection region, in which the course of a supply channel from a first channel portion with substantially parallel flow to the turbine axis flow into a second channel section, wherein the flow direction of the second channel section extends substantially in a direction perpendicular to the turbine axis plane ,
- the second channel section advantageously extends arcuately around the space in which the turbine is arranged.
- the deflection region is designed to be streamlined and low-turbulence, so that at least one outer wall delimiting the outer path of the channel in the region of the deflection with respect to the flow direction change is formed curved.
- a fictitious deflection axis can be assumed.
- the first outer wall is with respect to such a deflection axis radially outer boundary of the supply passage in the region of the deflection.
- the Krümungsradi- us the first outer wall can vary over the course of the deflection and is advantageously not less than 30%, in particular not less than 60% of the height of the supply duct in the region of the deflection.
- the respective smallest radial distance of the outer wall of a feed channel radially inner bounding first inner wall is considered, wherein in parallel to the notional deflection axis not constant cross section of Zu effetska- nals in the Deflection should be the consideration at the centroid of the cross section of the supply duct in the area of the deflection.
- the first inner wall of the supply channel runs without kinks and without steps, in particular monotonously curved, wherein the optionally varying radius of curvature of the inner wall is advantageously not less than 20%, in particular not less than 40% of said height of the supply duct.
- the supply channel is limited in the region of the deflection by surfaces of a lower part and a lid attached thereto, wherein the first channel section is formed between a switching device and the region of the deflection in the lower part.
- the first inner wall is advantageously formed on the lower part and the first outer wall on the lid, resulting in an advantageous design of injection molds for lower part and lid for the curved course of the boundary of the supply duct in the region of the deflection.
- Another significant improvement results from the streamlined and low-Verwirklebarmen design of an ending at the Anströmdüse last channel section, hereinafter referred to as the third channel section, for which an angular extent of at least 30 ° was assumed around the turbine axis.
- the design provides that a relative to the turbine axis radially outward, the supply passage delimiting outer wall, which is also referred to below as the third outer wall, kink-free continuously curved.
- the radius of curvature of the third outer wall is advantageously not less than 15%, in particular not less than 25% of the radius of the turbine, by which the outer radius of the annular arrangement of the turbine blades is understood.
- the radius of curvature may vary in the course of the third channel section.
- the third channel section advantageously extends with the constriction towards the continuous constriction, which increases with a towards the Anströmdüse Speed of the drive water flow is connected. Due to the bend-free, continuously curved course of the third channel section, there is a low flow resistance due to lacking or low turbulence and a high exit velocity of the drive water flow from the inlet nozzle in the direction of the turbine blades and an advantageously high torque to the turbine.
- the inner wall of the third channel portion advantageously also runs kink-free and step-free, in particular also monotonically curved.
- baffles such that they are inclined at the radial inner end edge with an outflow angle against a radial line, when flowing out of water from a currently acted upon by the Anströmdüse space between each other assigning baffles in a surrounded by the ring of the turbine blades Interspace one outflow direction of the water with one of the respective direction of rotation of the turbine opposite tangential flow compo- nente, which provides a power contribution to the starting torque of the turbine.
- the fins are concaved away from the gap.
- the turbine blades advantageously each have two guide surfaces facing away from each other and each associated with one of the two directions of rotation of the turbine, and are preferably narrower in their radially outer ends than at the radially inner ends.
- the gaps existing at the radially inner ends of the turbine blades between two guide surfaces to be oriented, through which water flows out of the intermediate space at said outflow angle, have a width in the circumferential direction which is advantageously between 30% and 200%, preferably between 50% and Is 150% of the distance of successive gaps.
- the distance between successive gaps is usually equal to the maximum width of the turbine blades at their radially inner ends.

- a sprinkler head with a nozzle arrangement can be connected, wherein such a connected sprinkler head is bidirectionally alternately pivotable about a rotation axis DA by means of the water-flowed sprinkler mechanism.
- the axis of rotation DA is vertical for sector sprinklers in the regular operating position, horizontal for square sprinklers.

- the flow of the drive water flow is deflected from an initially vertical main flow direction in the first channel section K1 1 to a horizontal direction when entering the second channel section the turbine axis TA approximately tangential main flow direction, so that the change of the main flow direction over the range of the deflection is about 90 °.
- An arrow MS represents the center of the flow.
- Such a deflection by 90 ° can be assigned a fictitious deflection axis whose direction is perpendicular to both the first and to the second main flow direction and which lies in the inner angle of the two main flow directions and with respect to which a radially outer boundary of the supply channel and a radially inner boundary of the Supply ducts in the area of the deflection exists.
