Description
Technical field
The utility model relates to waterscape fountain spray head technical fields, and in particular to critical positioning device.
Background technique
With the improvement of living standards, people are higher and higher to environmental requirement, urban environmental protection is increasingly by people's weight
Depending on.Fountain constantly appears in the square, park and other public fields in city as a kind of higher artistic water scenery of ornamental value
Institute.It can not only increase the humidity of surrounding air, reduce the dust in air, reduce air themperature, increase more for people's lives
Many temperament and interest are added.
In the prior art, fountain build the aesthetic come be usually by spray head location control and speed control come
It realizes, and spray head realizes that the premise of location control is that have an accurate datum mark, referred to as origin, the existing mode for looking for origin
For a positioning ring is arranged and fixed in spray head rotary shaft, positioning ring is rotated with spray head rotary shaft, there is an induction on positioning ring
Sensor is arranged on spray head rotary shaft base for point, and controller controls stepper motor and drives the rotation of spray head rotary shaft, when spray head rotates
When axis rotation drives the induction point proximity sensor of positioning ring, for sensor feedback signal to controller, controller assert this position
For origin, location information sets 0, completes to find origin process.Existing searching origin mode has the following disadvantages：1）It can not judge in advance
The position of origin, looking for origin that need to rotate most one whole circles (360 degree) can just find, and look for origin speed slow；2）It is mounted on spray head rotation
Electric power needed for equipment in shaft, signal transmission are difficult, and collector ring need to be arranged to avoid electric power signal cable winds.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems, provide a kind of critical positioning device for quickly searching origin,
It is rotated without whole circle.
For this purpose, technical solution used by the utility model is：Critical positioning device comprising stepper motor, fountain spray
Head rotary shaft base, fountain nozzle rotary shaft, critical positioning ring and sensor；The fountain nozzle rotary sleeve is located at fountain spray
It is connect on head rotary shaft base and with the stepper motor；It is arranged in fountain nozzle rotary shaft and fixes the critical positioning
Ring, the half of the critical positioning ring circumference are induction zone, the other half is non-inductive area, and the induction zone and non-inductive area combine
Place has at two, wherein is origin at one, another place is limit spacing point；The sensor is fixed on fountain nozzle rotary shaft machine
On seat.
Further, the induction zone height is greater than non-inductive area height.
Further, it is 0-180 ° that the origin, which rotates to the angular range of the sensor position,.
Further, the sensor is fixed on the fountain nozzle rotary shaft base by fixing piece.
The utility model has the beneficial effects that：The reduction of rotation angle described in origin is looked for, guarantees the normal work of fountain.
Detailed description of the invention
Fig. 1 is the critical positioning device structure schematic diagram of the utility model.
Fig. 2 is the critical positioning ring perspective view of the critical positioning device of the utility model.
Fig. 3 is the critical positioning ring main view of the critical positioning device of the utility model.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail：
Critical positioning device as shown in Figs. 1-3 comprising stepper motor 1, fountain nozzle rotary shaft base 2, fountain spray
Head rotary shaft 3, critical positioning ring 4 and sensor 5；The fountain nozzle rotary shaft 3 is set on fountain nozzle rotary shaft base 2
And it is connect with the stepper motor 1；The critical positioning ring 4 is arranged and fixed in fountain nozzle rotary shaft 3, it is described critical fixed
The half of position 4 circumference of ring is induction zone 41, the other half is non-inductive area 42 and 41 height of induction zone is greater than 42 height of non-inductive area,
The induction zone 41 and 42 junction of non-inductive area have at two, wherein are origin 43 at one, another is limit spacing point；Institute
Sensor 5 is stated to be fixed on fountain nozzle rotary shaft base 2 by fixing piece 51.
Angular range between the origin 43 and the sensor 5 is 0-180 °.
Working principle
When fountain nozzle needs to position, controller controls the rotation that stepper motor drives fountain nozzle rotary shaft 3, fountain
4 origin 43 of critical positioning ring rotation in spray head rotary shaft 3 and when proximity sensor 5,5 feedback signal of sensor to controller,
Controller assert that point on the basis of this position, location information set 0, completes to find origin process.
Of the invention is particular in that the current location for prejudging critical positioning ring 4 by sensor 5 is in induction
Area 41 or non-inductive area 42 come determine reach 5 position of sensor needed for direction of rotation, due to one on critical positioning ring 4
Point limit spacing, when limit point reaches 5 position of sensor with the operation of fountain nozzle rotary shaft 3, origin 43 runs to biography at this time
Rotation angle needed for 5 position of sensor is up to 180 °, and more traditional mode for looking for datum mark rotates angle and greatly reduces, and solves electricity
Force signal transmission problem ensures that spray head works normally.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this field
Technical staff for, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention is wrapped
It is contained in the protection scope of the utility model.
