Abstract
The invention discloses a kind of four loudspeaker sun trackers of pyramid, belong to solar tracking field.Tracking device of the invention includes pyramid loudspeaker, cross wedge shape partition-type structures, four photosensitive sensors, installs the rectangular box body that the section of photosensitive sensor is square.The rectangular box body bottom that four photosensitive sensors are square by sphere of movements for the elephants distributing installation in the section connecting with pyramid loudspeaker, wedge-shaped cross partition extends to horn mouth from the bottom of cabinet, and four sensors are segmented in four independent sections.For the present invention when the horn mouth of device is against sunlight, four sensors generate different photoelectric currents, and four sensors by up and down and left and right packet assembling asks photoelectric current poor, obtain the sun in the deviation of loudspeaker central axis, provide error indicator for solar tracking equipment respectively.
Description
Technical field
The present invention relates to the servo system fields of solar tracking or calibration north orientation, are based on pyramid more particularly, to one kind
The sun tracker of loudspeaker.
Background technique
In the tracking equipment of mirror-reflection solar power generation or the servo servo follow-up tracing equipment for north orientation calibration, it will connect
The solar radiation of receipts carries out photoelectric conversion and obtains tracing deviation information, and antenna then uses sun radio radiation to realize tracking.But
It is, since by sun visual angle, 0.53 ° is limited, it is difficult to accurate tracking and fixed north.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of sun trackers based on pyramid loudspeaker, meet servo-controlled machines
Structure needs the tracking of the sun, realizes the accurate fixed north to the servo-system for having fixed north to require by the sun.
To achieve the goals above, the present invention adopts the following technical scheme: a kind of solar tracking dress based on pyramid loudspeaker
It sets, including four photosensitive sensors, pyramid loudspeaker, cross wedge shape partition-type structures and cabinet, four photosensitive sensors press sphere of movements for the elephants
It is distributed in the bottom of box, top of the box is connected with the bottom end of pyramid loudspeaker；Cross wedge shape partition-type structures extend from the bottom of box
To the horn mouth of pyramid loudspeaker, pyramid loudspeaker is separated to form four independent toy trumpets, Mei Ge little by cross wedge shape partition-type structures
A photosensitive sensor is corresponding in loudspeaker.
Wherein, the cross wedge shape partition-type structures are engaged with the inner wall of pyramid loudspeaker, and section subtended angle is more than or equal to
0.53°。
Wherein, the inner wall of pyramid loudspeaker to the extended line in bottom of box direction in the center of photosensitive sensor, or partially
To the center of cross wedge shape partition-type structures.
Wherein, the edge of each photosensitive sensor and the bottom end of toy trumpet coincide.
Wherein, the shape of each photosensitive sensor is square, and cabinet is the rectangular box body that section is square.
Wherein, the pyramid loudspeaker, cross wedge shape partition-type structures and cabinet are opaque material.
The effect generated by adopting the above technical scheme is:
1, cross wedge shape partition-type structures of the invention are avoided that the angle measurement in the face sun is fuzzy, realize in the face sun
When accurately generate not by the deviation of sun angle effects.
2, the present invention can broaden measurement range by pyramid loudspeaker, be improved by the rectangular box body that section is square
The measured deviation precision of linearity range.

Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to Figures 1 and 2, the sun tracker of the invention based on pyramid loudspeaker, including four photosensitive sensor 1-
4, the rectangular box body 7 that the section of cross wedge shape partition-type structures 5, pyramid loudspeaker 6 and installation photosensitive sensor is square.It is photosensitive
Sensor 1-4 is arranged and is mounted on respectively the bottom for the rectangular box body 7 that section is square by equidistant sphere of movements for the elephants type；Section
The bottom end of the top connection pyramid loudspeaker 6 for the rectangular box body 7 being square；In the region that pyramid loudspeaker 6 and cabinet 7 surround
Cross wedge shape partition-type structures 5 are installed in portion, which extends to the horn mouth of pyramid loudspeaker 6 from the bottom of cabinet 7, is placed in photosensitive biography
The surface of sensor 1-4, bottom are adjacent to photosensitive sensor 1-4, and four sides are adjacent to 6 inner wall of pyramid loudspeaker and section is square
7 inner wall of rectangular box body.
Photosensitive sensor 1-4 selects 6 millimeters of rectangular photosensitive sensor, and cross wedge shape partition-type structures 5 are photosensitive sensor
1-4 is segmented in four independent regions.
Referring to Fig. 4, cross wedge shape partition-type structures 5 use wedge structure, essence when overcoming sun visual angle to track top
Degree influences.MN is the intersection of cross wedge shape partition-type structures 5 and photosensitive sensor.In order to guarantee tracking accuracy, the partition of cross wedge shape
The section extended line angle ∠ POL of structure 5 is 0.53 ° of sun visual angle.
It is that half maximum finds angular region referring to Fig. 3, ∠ GBA；∠ EAB is that half accurately tracks angle model
It encloses；∠ CAB is half wedge structure angle.The angle capture range of the tracking sun can be broadened using pyramid loudspeaker.Pyramid
Extended line from the inner wall of loudspeaker 6 to 7 bottom direction of cabinet at least in the center D of photosensitive sensor, can to cross wedge shape every
The off-centring of disconnected structure 5.The range that the subtended angle of pyramid loudspeaker 6 captures the sun as needed determines；The height root of pyramid loudspeaker 6
It is determined according to the angle that the side length and needs of photosensitive sensor track.
The brief course of work of the present invention is as follows: the present invention divides four photosensitive sensors when tracking the sun as shown in Figure 2
Not to find out two groups of photoelectric currents poor for (12,34) and left and right (14,23) grouping up and down, and upper next group of photoelectric current difference be corresponding to be obtained the sun and exist
The pitch deviation of pyramid loudspeaker central axis；It is inclined in the orientation of pyramid loudspeaker central axis that one group of left and right photoelectric current difference correspondence obtains the sun
Difference.The photoelectric current summation of four sensors, it will be respectively compared to obtain bowing after normalized with value and two groups of photoelectric current differences
Face upward gun parallax.
