The moving block 8 is provided with a motor 10, the right side of the motor 10 is connected with a gear 11, and the fixed rod 4 is provided with a tooth groove 12 which can be meshed with the gear 11.
The motor 10 adopts Siemens 1FK7042-5AF71-1EH 0-Z.
The lower end of the baffle 5 can rotate around the edge of the roof 1.
The upper side of the sun shield 2 is also provided with a solar cell panel 13.
The sun shield 2 is made of heat absorbing material.
The baffle 5 is of a V-shaped structure.
Example 1
In summer, the sun shield 2 on the roof 1 can absorb a part of heat to reduce the indoor temperature, rainwater is collected into the reservoir 7 in rainy days, partial heat of the roof 1 can be taken away by rainwater evaporation in sunny days, and the heat dissipation speed of water is slow, so that the indoor early and late temperature difference can be reduced; wind blows in from the upside of throttle plate 3, blows off from between sunshading board 2 and baffling board 5, utilizes the flow of air to increase the heat dissipation, and baffling board 5 that gas outlet 6 is connected has formed a chimney form, has promoted the circulation of indoor air greatly, reduces indoor temperature from a plurality of aspects, and the radiating effect is good.

Example 2
The adjustment range of the sun visor 2 is determined according to the change of the local solar altitude over the course of one year.
The solar altitude, denoted by h, is numerically equal to the altitude of the sun in the celestial horizon coordinate system. The solar altitude varies with the time of the locality and the declination of the sun. The declination of the sun is expressed by phi, the geographical latitude of the observation place is expressed by phi, the local time (hour angle) is expressed by t, and the calculation formula of the solar altitude angle is as follows:
sin H＝sinφsin+sinφcoscos t
the sun altitude is constantly changing in the same place day, and sunrise sunset hour angle all is 0 degree, and solar altitude is the biggest at noon, and noon hour angle is 0, and above formula can simplify to:
sin H＝sinφsin+cosφcos
wherein H represents the solar altitude at noon.
From the trigonometric function formula of the sum and the difference of the two angles, the formula can be obtained
sin H＝cos(φ－)
The declination angle of the sun is also called declination angle, and is the angle between the equatorial plane of the earth and the connecting line between the sun and the earth's center. The declination angle is shifted within the range of +23 ° 26 'and-23 ° 26' in a year cycle, and becomes a season mark. The day 6/month 21 or 22/year declination reaches the maximum value of +23 ° 26', called summer solstice, the day midday is the day with the longest sunshine time in the northern hemisphere and the shortest sunshine time in the southern hemisphere, wherein the sun is located right above the northern gyrocarscale of the earth. Then the declination angle is gradually reduced to 9 months and 21 days or 22 days which are equal to zero, and the global day and night time is equal to autumn minutes. The declination decreases to a minimum value of-23 ° 26' at 21 or 22 days 12 and month, which is winter solstice, when sunlight obliquely shines on the northern hemisphere, the short and long days and nights, and the opposite in the southern hemisphere. When the declination angle returns to zero, the declination angle is 3 months, 21 days or 22 days, and the four seasons are formed in this cycle. Since the declination value varies little from day to day, the declination angle for any day of the year can be calculated by the following formula:
＝0.3723+23.2567sinθ+0.1149sin2θ－0.1712sin3θ－0.758cosθ+0.3656cos2θ+0.0201cos3θ
where θ is the daily angle, i.e., θ 2 π t/365.2422,
here, t again consists of two parts, i.e., t — N0.
Where N is the product date, the term date is the number of days in the year, for example, 1 month 1 day for 1 product date, 365 months 31 days in 12 months in the same year, 366 in leap years, and so on.
N0 ═ 79.6764+0.2422 × (year-1985) -int [ (year-1985)/4 ]
Therefore, the adjusting range of the umbrella ribs is changed according to different installation places of the device, most human living areas in the northern hemisphere are integrated, and the adjusting range of the umbrella ribs is set to be 0-75 DEG
Example 3
In the tobacco field: latitude 37 deg. 52' longitude 121 deg. 39
Sun altitude equal to 90-latitude difference w
Latitude difference w is the latitude of the location w 1-the latitude of the direct sun beam w2
w1 w2 different hemispheres and accompanying balls are-the opening and closing angles of the sun shield 2 in different periods of the tobacco station area:

A＝52°.08＇
Summer solstice: a is 90-w
W＝37°.52＇-23°.26＇＝14°.26＇
A＝75°.34＇
Winter solstice: a is 90-w
W＝37°.52+23°.26＇＝61°.18＇
A＝90°－61°.18＇＝28°.42＇
In summer: a 75 °, 34 ≈ 75 ° sun visor 2 is horizontal 30 degrees.
In winter: a 28, 42 ≈ 28 sun visor 2 is horizontal 60 degrees.
Example 4
