The balancing pole 8 connects balance weight 10 by screw 9.
The servo motor I 15, servo motor II 17 are connect with single-chip microcontroller, wherein the common 89C51 of single-chip microcontroller model Series.
The balancing pole 8 is equipped with support plate 12, and support plate 12 is equipped with battery 13 and solar panels 14, solar panels 14 are connect by charging-discharging controller with battery 13, and battery 13 provides power supply for single-chip microcontroller.
The working principle of the irrigation sprinkler of this adjustable sprinkling domain shape are as follows:
Firstly, doing the elevation angle for some nozzle type determined and spraying the experiment of distance relation, general conclusion is obtained, i.e., The relationship fitting formula of distance and the elevation angle, then adjusting elevation angle device makes its decline, 21 falling head of the company's of obtaining screw rod and the elevation angle Relationship, and fit formula, and then calculate every 1 degree of the rotation of the servo motor II 17 even height of the variation of screw rod 21 and the elevation angle Then the angle of variation can be controlled the rotation of servo motor II 17 by single-chip microcontroller to adjust the distance of sprinkling distance, in addition be led to The rotation for crossing single-chip microcontroller control servo motor I 15 drives the rotation of gear wheel 6, and then mounting platform 5 is driven to rotate, i.e., controllable 360 degree rotation is realized in spray head horizontal direction, mounting platform 5 keeps slowly rotating, while needing to increase or reduce sprinkling distance When adjust 1 elevation angle of spray head.Finally, according to the needs of different terrain shape, the elevation angle for adjusting spray head to spray domain and landform Match, reduce out-of-bounds fountain height, improves uniformity coefficient of sprinkler irrigation.
The following are the concrete operation steps for the process that the elevation angle increases: single-chip microcontroller, which transmits the electrical signal to servo motor I 15, makes it Rotation, then motor output shaft drives motor gear I 16 to rotate, while the gear wheel 6 of engagement being driven to rotate, thus mounting platform 5 with And all components rotate on mounting platform 5, universal wheel 7 is rolled along rotary table 31 at this time;At the same time, single-chip microcontroller sends signal Make its rotation to servo motor II 17, then motor output shaft drives motor gear II 20 to rotate, while driving the pinion gear of engagement 30 rotations, since the screw thread inside through-hole 29 cooperates with screw rod 21, and 29 lower end of through-hole connects bearing 19, therefore 29 He of through-hole Part rotates together in bearing 19, but height does not change, and screw rod 21 at this time can decline, while connecting rod 22 can be along hinge The axle center of chain I 23 and hinge II 24 rotates, and spout adjusting rod 26 can rotate along the axle center of hinge II 24, so that spray Mouth adjusting rod 26 tilts down, therefore 1 elevation angle of spray head rises.
Monolithic can not also be used using the method control servo motor I 15 and servo motor II 17 of manual control simultaneously Machine control.
It is respectively square region (square region boundary) and delta-shaped region (delta-shaped region circle that irrigation sprinkler, which sprays region, Limit) place, the sprinkling domain using conventional rocker formula spray head is round (a circle sprinkling domain border), it may occur that the feelings of drain spray Condition, and using can adjust sprinkling domain shape irrigation sprinkler sprinkling, can substantially spray square region and triangle domain, save water money Source ensure that region uniformity coefficient of sprinkler irrigation
The beneficial effects of the present invention are:
1, this irrigation sprinkler ensure that the accuracy in sprinkling irrigation region, largely reduces drain spray, resprays, the situation out-of-bounds sprayed, Water resource is saved;
2, by the gear drive of special designing, screw rod transmission makes movement precisely, while balance weight enhances device entirety Stability guarantees sprinkling will not be caused to deviate because of the recoil strength of water flow during sprinkling;
3, spray head combination arrangement is carried out using square spray field, can solve round spray and filling surface combination has the case where overlapping;
4, the rotation using universal wheel on rotary table ensure that stationarity when mounting platform rotation;
5, installation is simple and convenient, has very strong ornamental value, is suitable for lawn, Landscape etc..
