Abstract
The utility model provides a current rotator for a lifting-type buried sprinkler head driving device, which comprises a cone section (44) and a column section (42) that are hollow therein and connected with each other. The axle centers of the cone section (44) and the column section (42) are overlapped. The lower part of the cone section (44) is provided with an annular hole (45). Current inlets (43) are uniformly distributed on the column section (42).
Description
Technical field
The utility model belongs to water-saving irrigation accessory structure field, particularly relates to a kind of current rotor that is used for the ascending and descending type buried spray head drive unit.
Background technique
All adopt the jet pipe technology to solve the water requirement at present in the higher place of water consumptions such as urban green space, golf course.The structure more complicated of existing jet pipe product, its structural type is, through the water that filters, rush at a certain angle and be positioned at the impeller that a multi-disc aerofoil profile on the end face constitutes, drive a main axis rotation, have a driving gear on this axle, after slowing down by several grades of gear pairs, the rotation of driving nozzle reaches the sprinkling purpose.In this driving structure,, bring big difficulty for manufacturing and assembling because gear pair is too much; Especially the driving gear rotating speed is higher, and this just requires the installation precision height of each gear shaft, the accuracy of manufacturing height of each gear axis hole; Especially,, have only 0.5 basically, gear manufacturing and assembly precision are all had higher requirements because each gear die number average is less.So driving structure manufacture cost height of this structure.And owing to from first order gear, up to nozzle, be the hard connection by gear, when variation in water pressure, the angular velocity of rotation of nozzle tip directly changes obviously with water pressure fluctuations; If variation in water pressure is frequent, engaging gear adjutants at different levels are produced certain infringement.
Has bigger value so research and develop simple and practical driving structure.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of current rotor that is used for the ascending and descending type buried spray head drive unit simple in structure is provided.
To achieve these goals, the technological scheme of employing is as follows:
A kind of current rotor that is used for the ascending and descending type buried spray head drive unit, comprise inner hollow and continuous conical section and cylindrical section, the axle center of described conical section and cylindrical section is overlapping, and the bottom of described conical section is provided with a looping pit, and described cylindrical section is provided with equally distributed inflow port.
The utility model is as the parts of ascending and descending type buried spray head drive unit, its role is to produce the current of rotation, rotate to impact or to drive other associated components, so the utility model is by being provided with inflow port at cylindrical section, outside it, enter inner current and just can form rotary water current, and then impact or drive other parts that are installed in its inside and rotate through inflow port.
Further, the utility model is provided with a plurality of inflow port, and inflow port evenly is provided with along the circumference of cylindrical section.
The section of described inflow port is a square or rectangular, and the distance center axis plane and the internal face of cylindrical section farthest is tangent.
The section of described inflow port also can be circular or oval, and the internal face of the bus of distance center axis inflow port farthest and cylindrical section is tangent.
By above-mentioned inflow port setting, rotation that just can convenient and swift realization ingoing stream.
The upper end of cylindrical section described in the utility model also is provided with the seal ring mounting groove.Install seal ring by the seal ring mounting groove, realize sealing with the ascending and descending type buried spray head housing.
The utility model is simple in structure, is brand-new driver part, effectively overcomes the deficiency of existing nozzle structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is a side view of the present utility model;
Fig. 4 is the sectional view of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structure of the present utility model is shown in accompanying drawing 1-4, and its general structural features in mind is to be made of conical section 44, cylindrical section 42, seal ring 6 mounting grooves 41, and inside is hollow.A looping pit 45 is arranged at the bottom of described conical section 44.Have equally distributed several inflow port 43 on the wall of described cylindrical section 42.The section of inflow port 43 can be square, rectangular, circle or other shapes.When inflow port 43 was square, rectangular, the distance center axis plane and the internal face of cylindrical section 42 farthest was tangent; When inflow port was other shapes such as circle, ellipse, its internal face apart from the bus of shaft axis inflow port 43 farthest and cylindrical section 42 was tangent.
The utility model and other parts cooperatively interact and form the drive unit of ascending and descending type buried spray head, make when current pass through the utility model in drive unit, separated into two parts, wherein a part directly enters the slipstream producer through the looping pit 45 of slipstream producer, another part enters the slipstream producer through the exterior face of slipstream producer from tangential inflow port 43, and the tangentially internal face rotation of the cylindrical section 42 of flow generator, impact is arranged on the parts of slipstream producer inside, make it rotation, thereby drive shower nozzle rotation water spray.
