The specific embodiment

Consult Fig. 1-shown in Figure 3, the utility model comprises sprinkler head and pressure water-supply system, wherein, sprinkler head is to be closed by interior sprinkler head and outer sprinkler head cover insert group to constitute a sprinkler head integral body, and inside and outside two cover sprinkler heads are respectively equipped with separately independently pressure water-

supply system

14 and 15; The water spray simultaneously but any one independent water spray of two cover sprinkler heads or two kinds of current cross can make fountain produce water spray moulding in different poses and with different expressions.

Interior sprinkler head and outside sprinkler head internal interval certain distance be provided with respectively and be connected with in several flow deflector 6 and flow deflector 7 outside several.

Above-mentioned outer sprinkler head is closed by water inlet end pipe 1, outer tube body 2 and outer bush 10 cover insert groups and constitutes, and adopt welding manner to connect as one, welding one reducer pipe 4 between the upper end of outer tube body 2 body and lower end body makes the upper end pipe diameter less than the lower end pipe diameter.Water inlet end pipe 1 and outer tube body 2 link to each other with separately pressure water-

supply system

14 and 15 respectively; The inside of outer tube body 2 adopts welding manner to be connected with several outer flow deflectors 7.Interior flow deflector 6 and outer flow deflector 7 play the guiding role: by improving the fluidised form of water, can prevent the generation of vortex flow, make the current of ejection more smooth and easy.

Sprinkler head is closed by interior tube body 3 and interior guide pin bushing 8 cover insert groups and constitutes in above-mentioned, and the upper end pipe diameter of interior tube body 3 is less than the lower end pipe diameter.

Insert from the upper end of interior guide pin bushing 8 sleeve pipes and a stepped inner core-body 5 is installed, spring 9 is installed on the inner core-body 5, the water diversing head 11 of cover unification enlarging shape on the inner core-body 5 of spring 9 upper ends, the upper end of inner core-body 5 is provided with screw thread, and adopts pad 13 nuts 12 fixing; Adopt welding manner to be connected with flow deflector 6 in several between interior tube body 3 and the inner core-body 5.

Inner core-body 5, can be adjusted the gap of water diversing head 11 to interior guide pin bushing 8, thereby adjust the water yield by adjusting the position of pad 13 nuts 12 by spring 9 carrying water diversing heads 11.

Inside and outside two cover sprinkler heads link to each other with separately pressure water-

supply system

14 and 15 respectively, and pressure water-

supply system

14 and 15 is driven by variable controller and controls; Variable controller is to be connected and composed successively by water pump 16, frequency converter 17 and computer programmable controller 18.By the VFC control sprinkler head water yield and the water velocity of 17 pairs of water pumps 16 of frequency converter, constantly form some novel water shapes by the flow of two strands of different current and the variation of flow velocity.Frequency converter 17 again can be by 18 controls of computer Programmable Logic Controller.

Operation principle of the present utility model: shower nozzle of the present utility model is interior overcoat inserting combined type structure, and inside and outside shower nozzle all has separately independently pressure water-supply system, and two overlap independently, and pressure water-supply system drives control by variable frequency converter respectively.When opening the frequency converter switch, Frequency Converter Control pump rotary speed, thereby the size of what and water velocity of control shower nozzle water yield; Simultaneously, any one sprinkler head is opened.When sprinkler head is sprayed water in allowing separately, can present the effect of day column that inclines, at this moment, this fountain is equivalent to an annular space sprinkler head.Regulate frequency converter and can adjust the height of water column, if when outer sprinkler head is sprayed water, fountain presents the view of the heavenly maids scatter blossoms.Adjust the relative position of water diversing head and inner core-body, and suitably adjust nut, can change the water spray shape; when inside and outside two cover sprinkler heads are sprayed water simultaneously; two strands of current are gathered together, and form the water shape of shapes such as likeness in form morning glory, umbrella, luminous wine glass, pine and cypress, jujube nuclear, pagoda, lifelike image.Suitably adjust frequency converter, can produce hundreds of water shape, water shape is ever-changing, and is in different poses and with different expressions, makes people that a kind of illusion sensation that goes off to dreamland be arranged seemingly, makes the people fresh and new, relaxed and joyful.

The utility model is simple in structure, and control is convenient, and is workable, can be used in outdoor multiple fountain water scenery engineering.

Water pump, frequency converter and computer programmable controller are the commercially available prod, and the technology of not specified (NS) is a prior art.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
