Abstract
Aiming at effectively solving the problem that the detection becomes invalid because the effective measuring ranges of most of photo sensors adopted by a photoelectric sun tracking sensor are reached or exceeded when the sun rays are normal, the utility model provides a sunlight intensity lightening device. The sunlight intensity lightening device is characterized in that the device adopts a cylindrical body; an annular cover is arranged at the top of the cylindrical body; a transparent body is arranged at the upper half part of the cylindrical body; a cylindrical through hole is formed in the transparent body; a cylindrical base is arranged at the lower half part of the cylindrical body; four cylindrical through holes are uniformly formed on the base along a certain semi-diameter; the cylindrical through hole at the upper part and the cylindrical through holes on the base form four tiny slots which are divided into two groups; the tiny slots in each group are symmetrical with each other; and the center connecting lines of the two groups of tiny slots are mutually vertical. The sunlight intensity lightening device allows the intensity of the incident sunlight to be reduced within the effective measuring ranges of the photo sensors, and enables the sunlight intensity to be suitable for the detection of the photo sensors, therefore the sun tracking sensor can accurately judge the position of the sun so as to satisfactorily track the sun.
Description
Technical field:
The utility model relates to solar utilization technique, is specifically related to solar tracking technical field in the solar energy system.
Background technology:
When traditional energies such as electric power, coal, oil signal for help repeatedly, when energy problem became the bottleneck of restriction international community economic development day by day, more and more countries came into effect " sunlight program ", and the development and use solar energy resources is sought the new power of economic development.Sun power more and more causes people's attention as a kind of reproducible new forms of energy.Photovoltaic generation is a kind of mode that sun power utilizes, and the effect of and environmental protection energy-conservation because of it is subjected to paying attention to widely.
At present, various types of sun trackers emerge in an endless stream, but comparatively commonly used be the photo-electric sun tracker.Its sensing element mainly is a kind of photosensitive device that utilizes light action to make the conductance marked change of semiconductor material.At present domestic commonly used have gravity type, electromagnetic type and electrodynamic type sun tracker, these tracking means all use photosensitive device to make the core component of sensor.Usually in these sensors, several photosensitive devices are installed in almost airtight column shape container both sides, column shape container has symmetric beam to be shining into opening, when the both sides of column shape container and sunray are not parallel, the photosensitive device of the both sides of column shape container does not wait because of being subjected to solar radiation intensity, the electric current of its output will have deviation, and deviation signal is amplified through amplifying circuit, adjust angle by adjusting mechanism and make the tracking means aligning sun finish tracking.
But, the photosensitive device of the employed most of types of photo-electric sun tracker is when sunray normally shines, even the light intensity of the backlight side of container makes that also photosensitive device meets or exceeds effective range, though this moment, there was the equation of light in the both sides of container, but the both sides photosensitive device all will reach simultaneously or exceed effective range, promptly can not produce deviation signal yet, lose efficacy thereby cause to detect.In view of above reason, the utility model proposes a kind of sun light intensity reducer and can solve problem mentioned above effectively.
Summary of the invention:
Problem at above-mentioned photo-electric sun tracker existence, the utility model proposes a kind of sunlight strength reducer that is used for sun-tracking sensor, this device is characterized in that it is a right cylinder, one ring cowling is arranged at the top, the first half has a cylindrical hole, Lower Half is a cylindrical seat, and base has four cylindrical holes in the even branch of certain radius.Four cylindrical holes of first half cylindrical hole and base form four small slits, and four slits are symmetrical in twos, and the line of centres is vertical mutually.It can be attenuated to the sunlight intensity of incident the effective measuring area of photosensitive device, makes light intensity can not cause sensor to lose efficacy, thereby makes tracker can judge exactly that the realization of the sun to the tracking of the sun with occupying a good place.
Description of drawings:
Fig. 1 master looks and cut-open view
Fig. 2 overlooks and cut-open view
Among Fig. 11: ring cowling; 2: logical light body; 3: base
Base is a cylinder, four cylindrical holes that on the cylinder certain radius, distributing symmetrically and evenly, the aperture is slightly larger than the external diameter of light-sensitive device, and the height of cylinder is greater than the setting height(from bottom) of light-sensitive device, make it to cover corresponding light-sensitive device fully, make light-sensitive device not be subjected to the impact of surround lighting.
Logical light body also is a cylinder, and it is installed on the base, and external diameter is identical with base, and it has a concentric cylinder through hole, and the aperture is slightly larger than the diameter of a circle with four cylindrical hole inscribes of base, and its Main Function is logical light.
Ring cowling is a thin annulus, and external diameter is slightly less than the lower cylindrical body diameter, is embedded on the logical light body, and the internal diameter of ring is identical with the diameter of a circle of four cylindrical hole inscribes of base, and its main effect is can just in time block the printing opacity slit fully when the light vertical irradiation.
Embodiment:
Whole device is by 3: base; 2: logical light body; 1: ring cowling; Assemble successively from top to bottom, when the sunlight vertical incidence, light is just in time blocked by ring cowling, it is minimum that the photosensitive device light income that the light that enter by the slit this moment is installed symmetry reaches simultaneously, when light has certain deflection, meet light side incident light quantity more than backlight side, correspondingly the difference between current mutation of photosensitive device is big, and the variation that detects this value by subsequent conditioning circuit comes controlled motion mechanism to make it to finish tracking to the sun.Because sunshine is to import by small slit, its intensity has obtained very big weakening, even also can not cause photosensitive device to exceed its effective range under the strongest illumination, thereby satisfies the requirement of omnidistance solar tracking.
