Characteristics of the present utility model also are,
Worm gear wherein is provided with dial, and the pointer of indication angle is installed on the worm screw back shaft.
The beneficial effect of the utility model semi-automatic sun optrack is, usually used the high power consumption of photoinduction system at follow the tracks of sunlight mechanism in the past, expensive drawback, propose the use servo electrical machinery system and adjusted horizontal angle, the method of the manual adjustment angle of pitch, both guarantee the reliability of tracking accuracy and system, greatly reduced operation cost again.
Description of drawings
Fig. 1 is the structural representation of the utility model semi-automatic sun optrack;
Fig. 2 is the vertical view of the utility model semi-automatic sun optrack.
Among the figure, 1. solar energy photovoltaic panel, 2. main shaft, 3. worm screw, 4. worm gear, 5. dial, 6. collar bush connecting axle, 7. gear, 8. servomotor, 9. collar bush, 10. base for supporting, 11. worm screw back shafts.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
In fact geographic latitude is equivalent to the line in certain any same the earth's core (center of circle) on the earth, and the angle between the equator; In fact sun altitude is equivalent to sunray (supposing that sunray is a directional light) with the angle between the local excessively disc tangent line (horizon); The direct sunlight line is perpendicular to earth surface (disc), the inevitable horizontal line vertically of direct projection light so, and the extended line of direct sunlight line must be crossed the earth's core.Usually we represent the somewhere height of the sun at noon with h, and it is numerically equal to the altitude of the sun in the coordinate system of celestial horizon.Sun altitude along with local time and the variation of the declination of the sun and changing.Solar declination represents with δ, and observation ground geographic latitude represents with φ, local time (hour angle) represent that with t the computing formula of sun altitude is arranged: sin h=sin φ sin δ+sin φ cos δ cos t.Day rises sunset, and sun altitude is constantly to change in the same place one day.Angle all is a zero degree during sunrise sunset, positive period of the day from 11 a.m. to 1 p.m the sun altitude maximum.Because the local time t=0 in the time of high noon, so the sun altitude high noon the time can calculate with following formula: for the Northern Hemisphere, H=90 °-(φ-δ); For the Southern Hemisphere, H=90 °-(δ-φ).Summer solstice, the sun direct projection tropic of cancer, i.e. north latitude 23.5 degree; The winter solstice sun direct projection tropic of Capricorn, i.e. south latitude 23.5 degree.Centre 47 latitudes of being separated by, be 365.26/2=182.63 days half a year.From Winter Solstice in the Summer Solstice, subsolar point moves southwards from north latitude 23.5 degree, move 47/182.63=0.2574 latitude every day, be to move on to south latitude 23.5 degree the winter solstice after half a year, northwards put again then, with the speed of 0.2574 latitude every day, through 182.63 days, promptly the summer solstice was got back to north latitude 23.5 degree equally.Can very accurately find the latitude of subsolar point every day, i.e. solar declination δ by this.
The structure of the utility model semi-automatic sun optrack, as shown in Figures 1 and 2, comprise that the bottom surface is provided with the base for supporting 10 of column, be vertically installed with main shaft 2 on the column of base for supporting 10, the outside of main shaft 2 is connected with collar bush 9 by collar bush connecting axle 6, one end of main shaft 2 is connected with servomotor 8 by gear 7, and gear 7 is made up of series of gears system; The other end of main shaft 2 is provided with solar energy photovoltaic panel 1, the middle part of main shaft 2 is provided with the transmission mechanism that is formed by connecting by worm gear 4 and worm screw 3, worm screw 3 is connected with collar bush 9 by worm screw back shaft 11, worm gear 4 is fixed on the column of base 10, worm gear 4 is provided with dial 5, and the pointer of indication angle is installed on the worm screw back shaft 11.
The course of work of the present utility model is, the data that go out according to calculated in advance, calculating and tape deck location be the sun altitude in some time in such a month, and on such a day, the data that contrast has calculated are made dial 5, manually rotation worm gear 4 makes worm gear 4 move in a circle along worm screw 3, reads the angle of pitch in this moment from dial 5, worm screw 3 is connected with collar bush 9 by worm screw back shaft 11, and then realizes the luffing angle adjusting of solar energy photovoltaic panel 1; Gear ratio by choose reasonable servomotor 8 and setting gear 7, pass through gear 7 by servomotor 8, desired speed is reached main shaft 2, thereby realize that main shaft 2 drives solar energy photovoltaic panel 1 requiring uninterruptedly at the uniform velocity rotation in the time period, constantly guarantees that solar energy photovoltaic panel 1 is over against solar incident ray.Fall along with the east of one day sun rises the west, aligning elevation gear and horizontal adjusting mechanism common guarantee solar energy photovoltaic panel 1 are followed the tracks of the sunlight incident direction constantly.
The utility model semi-automatic sun optrack adopts the uniterminal axis tracking means, and with the rotation of motor driving main shaft, the manual adjustment main shaft angle of pitch makes this uniterminal axis tracking means aim at the sun all the time.It is by the photoinduction system that tradition is followed the tracks of, and equipment operation cost height, and the utility model drives and the manual adjustment pitching with simple motor had not only reduced operation cost but also guaranteed the reliability of system.
