Abstract
The utility model provides a hydraulic driving unit for a lifting-type underground sprayer driving device. A round disc structure (8) constitutes the main part of the hydraulic driving unit; an axial hole (81) is formed at the center of the round disc (8); and an inflow hole (82) is formed in the vicinity of the axial hole (81).
Description
Technical field
The utility model belongs to water-saving irrigation accessory structure field, particularly relates to a kind of hydraulic drive 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 hydraulic drive 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 hydraulic drive that is used for the ascending and descending type buried spray head drive unit, its main body are disc structure, and the center of described disk is provided with axis hole, are provided with flow-in hole near the described axis hole.
The utility model is as one of parts of ascending and descending type buried spray head drive unit, its role is to produce rotation and the final shower nozzle rotation water spray that drives, so the utility model passes through disc structure, and be provided with axis hole at the center of disk, be provided with flow-in hole near the axis hole, be connected with other rotary component by axis hole, drive and be rotated by other rotary component, allow current to enter by flow-in hole simultaneously, driving the current that entered in rotation also rotates, thereby the final parts rotation that is connected with shower nozzle, the rotation water spray of realization shower nozzle of driving.
In the technique scheme, an edge of described disk is provided with outer shroud, adopts outer shroud, and the feasible current that enter by flow-in hole are fettered by outer shroud when rotating, can not reveal easily, increase the rotation of current simultaneously.
The one side of described disk is provided with the eddy flow rib.By the obstruct of eddy flow rib, be convenient to the current rotation that enters by flow-in hole.
Further, eddy flow rib projection certain altitude, its cross section is square, rectangular or semicircle.
Baseline one end of described eddy flow rib links to each other with outer shroud, and the other end terminates in the flow-in hole edge, and points to the center of axis hole.
The baseline of described eddy flow rib is a curve, and described curve is one section circular arc, one section ellipse or one section involute.
As another kind of structure, the baseline of described eddy flow rib also can adopt straight line.
As preferred version, the utility model is made of axis hole, several flow-in holes, several equally distributed eddy flow ribs, substrate and outer shroud, described substrate is perpendicular to axis hole, described flow-in hole is positioned on the substrate and gets through substrate fully, flow-in hole is near axis hole, and parallel with axis hole, described outer shroud is positioned at the substrate outward edge, and described eddy flow rib is positioned on the substrate.
The utility model is simple in structure, can be connected with other rotary component by axis hole, drive and be rotated by other rotary component, allow current to enter by flow-in hole simultaneously, driving the current that entered in rotation also rotates, current by rotation drive other driver part rotation, thereby finally drive the rotation water spray of shower nozzle.
