Specific embodiment
Embodiment
As shown in Figure 1-2, a certain moment wind direction is east, after sensor sensing to wind direction and wind speed, signal transmission is given
Single-chip microcomputer, draws after the sequential operation on single-chip microcomputer and pressurize x kPa to the water column being oriented east, should be to the water being oriented west
Y kPa of post pressurization (obviously, y<X), now Single-chip Controlling Master Control Room gives whole y kPa of pressurizations of supplying water, therefore in jet pipe bottom
Should be nrad/s, direction Chao Dong to the pressure of the water column supplementary (x-y) kPa being oriented east by calculating the rotating speed of impeller.By
If the energy that wind-force provides can not meet rotation speed requirements, dump energy is provided to keep stablizing of rotating speed by small electromotor.
Because the direction of fan is towards needing the direction of maximum pressure with wind in the opposite direction, therefore with impeller
It is oriented centrage, be gradually gradual change to the pressure effect during transition of both sides, that is, muzzle velocity is by upwind maximum speed
Spend the minimum speed gradual change of down wind.So, be achieved that desired, it is to avoid the impact to sprinkling irrigation for the wind, make sprinkling irrigation
Scope and effect reach desired value.
Using wind energy first it is to be understood that wind direction and wind speed, can be realized by wind direction, air velocity transducer.In overall control
A piece of greenery patches in, can according to greenery area and topographical conditions, arrange multiple observation stations so that adjustment after spray irrigation system reach
To the overall effect being suitable for.
The kinestate of the little water droplet that spray irrigation system sprays is a kind of oblique upper paraboloiding movement, is subject to itself in this process
Gravity and the impact of air drag.Due to shower nozzle rotary water jet, each moment has towards different water columns from shower nozzle ejection.False
Subduing the wind syndrome will not change direction at short notice, then wind-force to and its equidirectional water column act as accelerate, and to and its direction
Contrary water column act as slow down.In order to adjust spray field with have wind before consistent, then should adjust different directions water column
Muzzle velocity and exit angle.It is also contemplated that shower nozzle is in higher speed rotation status in water spray, if changing water spray angle,
Allow spout continuous adjustment direction in rotary course, like this will be very high to the intensity requirement of shower nozzle, also just very simultaneously
It is easily damaged.Therefore, reach, by changing water column muzzle velocity, the purpose realizing normal sprinkling irrigation using wind energy.
People's often impact to sprinkling irrigation without noticing of weather.For example, it is often whole after spray irrigation system is opened by staff
Day sprinkling irrigation, during high noon, illumination is strong, and the water droplet being sprayed onto on plant leaf blade just serves the effect of convex lenss optically focused this moment, very
Easily plant leaf blade is burnt；Rainfall reach certain level, soil moisture big when, plant is not at exsiccosis,
Do not need to be sprayed.
It is not necessary to measure to intensity of illumination high precision in sprinkling irrigation, thus photoconductive resistance-voltage conversion circuit is selected to enter
Row sensing controls.So obtain is DC voltage, facilitates single-chip microcomputer identification to utilize.
Soil humidity sensor, again without high-acruracy survey, therefore adopts resistance-type or capacitive dew cell,
In conjunction with voltage conversion circuit, the DC voltage input single-chip microcomputer obtaining is controlled.
Optical sensor and soil humidity sensor combine intellectuality is carried out to system, the basis of Automated condtrol is exactly
The programming Control of single-chip microcomputer, the core of controller is single-chip microcomputer.
For the wind-force air velocity transducer spoken of in conjunction with Part I, the electrical signal data that these sensors collect will be passed
Defeated processed to single-chip microcomputer, also need to multigroup experimental data among these to carry out sequencing setting.After setting, single-chip microcomputer
Output digital quantity, digital quantity is through D/A conversion circuit input voltage or electric current, thus being controlled to whole system.
When soil humidity sensor senses that soil moisture is more than some value, single-chip microcomputer can control system stop
Work；When optical sensor senses that intensity of illumination is more than a certain value, quit work again by single-chip computer control system.
Bernoulli equation is also referred to as " pressure equation ", and it is one of One-Dimensional flows problem important relationship formula, Er Qie
In entirely incompressible, time independent fluid mechanics field, also there is basic importance.Bernoulli equation is preferable barotropic fluid
When making steady motion under having the effect of gesture body force, the equation of motion (i.e. Eulerian equation) is along expressive movement obtained from streamline integration
The equation of fluid mechanical energy conservation.For the incompressible homogeneous fluid in gravitational field, equation is p+ ρ gh+ (1/2) * ρ v^2=
c.Flowing medium velocity increases, and pressure is reduced by；Speed reduces, and pressure just increases；Speed is reduced to zero, and pressure just reaches maximum (reason
By stagnation pressure above should be equal to).The present invention utilizes this principle, upwind water column pressurization is accelerated, thus realizing Radix Saposhnikoviae purpose.
