Abstract
The utility model provides a sunlight irradiation angle sensor with a light-tight barrel, which belongs to the sensor in solar energy utilizing equipment for tracing optimal sunlight irradiation angle. The sunlight irradiation angle sensor comprises a light-tight barrel and a pored cover board, wherein the pored cover board has a light inlet hole; one end of the light-tight barrel is closed and the other end is open; the pored cover board seals the open end of the light-tight barrel; the surface, facing the pored cover board, of a circuit board is provided with at least two photosensitive elements. The direct sunlight is separated from interference light rays such as environment reflected light in natural light by using the light-tight barrel and the pored cover board, the sensing elements only sense the direct sunlight and irradiation angle change of the direct sunlight on the ground, therefore the interference light rays such as the environment reflected light are avoided; furthermore, the sunlight irradiation angle sensor can be used normally for conducting the solar energy utilizing equipment to track the direct sunlight.
Description
Technical field
The utility model belongs to technical field of solar utilization technique, particularly in solar utilizing equipment, and the solar light irradiation angular transducer of the best irradiating angle of sun-tracing light.
Background technology
Present solar light irradiation angular transducer is to become " cross " arranged in a crossed manner with two opaque dividing plates, and four empty positions that " cross " intersects are installed respectively photo-sensitive cell, in translucent cover, whole photo-sensitive cells being sealed in.Shortcoming is that photo-sensitive cell can not only be experienced sunshine, can also experience the reflected light of environment, in the output signal of this sensor, containing stray light, is the reflected light of environment, solar light irradiation angle situation of change signal is had to distortion in various degree.When the stray light of environment changes greatly or when stray light is very strong, this solar light irradiation angular transducer just can not normally command solar utilizing equipment to carry out the rotation of sun-tracing light.
Summary of the invention
The purpose of this utility model is to provide the stray lights such as Ambient, can not affect the solar light irradiation angular transducer of normal commander's solar utilizing equipment sun-tracing direct light.
Structure of the present utility model is:
Solar light irradiation angular transducer with light tight cylinder, comprise photoelectric commutator 1, photoelectric commutator 1 is located at circuit board 2 surfaces, photoelectric commutator 1 comprises photo-sensitive cell 6, it is characterized in that: also comprise a light tight cylinder 3 and have blind patch 4, have in blind patch 4 and be provided with into light hole 5, light tight cylinder 3 has one end sealing, has one end to have opening, has blind patch 4 by the openend sealing of light tight cylinder 3; Circuit board 2 is located in light tight cylinder 3, circuit board 2 with have blind patch 4 parallel, circuit board 2 is to there being blind patch 4 sides to be provided with at least two photo-sensitive cells 6;
The minimum widith that enters the diameter in light hole 5 or enter light hole 5 is D;
6D≥H≥D；
Light tight cylinder 3 is provided with signal output plug 7, and signal output plug 7 is connected with photoelectric commutator 1.
The meaning that photoelectric commutator 1 is located at circuit board 2 surfaces is: the parts of photoelectric commutator 1 can be located at circuit board 2 certain one side, also can be located at the two sides of circuit board 2.
Light tight cylinder 3 has one end sealing, another openend is had again blind patch 4 sealings, only have the sunray limiting in angular range could be by there being the light hole 5 of entering of blind patch 4 to be radiated on photo-sensitive cell 6, the stray lights such as Ambient can not enter light tight cylinder 3, the stray light such as Ambient can not affect the rotation that sensor is normally commanded solar utilizing equipment sun-tracing, only have the sunray limiting in angular range just can reach the photo-sensitive cell 6 of sensor, make solar utilizing equipment always utilize to greatest extent sun power.
The scope of D size and H size is set, and can be used for the sensitivity that regulates sensor commander solar utilizing equipment sun-tracing to rotate.As too little in D or H is too large, produce some dead angles and can not receive sunray, and lose the function that regulates sun-tracing.As D is too large or H is too little, sunshine can be irradiated to each photo-sensitive cell 6 any time, can not generating portion photo-sensitive cell 6 illuminated, the not illuminated fruit of another part, thus also lose the function that regulates sun-tracing.Experimental results show that 6D >=H >=D is good selectable range.
Enter the shape in light hole 5 and select, the structure of solar utilizing equipment is relevant with the rotating manner of sun-tracing with selecting:
There is the light hole 5 of entering of blind patch 4 to elect circular port as, can control tracking equipment and do two dimension operation, i.e. east, west, upper and lower four direction sun-tracing.
There is the light hole 5 of entering of blind patch 4 to elect slot as, be applicable to only east-west direction position sun-tracing, slot can adapt to the altitude of the sun of Various Seasonal, and the sunshine of the different angles of pitch can both be radiated on photo-sensitive cell 6 by the light hole 5 of entering of blind patch 4.
Having the outside surface of blind patch 4 to be provided with transparent glass or printing opacity glue-line 8, is mainly for waterproof and prevent that environment foreign matter from affecting normal operation of sensor.
Advantage of the present utility model: with light tight cylinder with have blind patch to carry out separated to stray lights such as the direct sunlight in natural light and Ambients, making photo-sensitive cell only experience direct sunlight and the direct sunlight irradiating angle on ground changes, thereby can avoid the stray lights such as Ambient, can be used as the solar light irradiation angular transducer of normal commander's solar utilizing equipment sun-tracing direct light.
