Abstract
The utility model relates to a focus point shifting diffusion sun tracking device which comprises a convex lens, direction photosensitive elements and a center photosensitive element. The direction photosensitive elements and a center photosensitive element are arranged below the convex lens. The direction photosensitive elements are respectively arranged in four quadrants of a plane coordinate, and the center photosensitive element is arranged on the origin of the plane coordinate. Detection signals of the photosensitive elements are output to a monitoring module. The diffusion sun tracking device with the shifting focus point has the advantages that through arrangements of the direction photosensitive elements and the center photosensitive element, a best illumination direction is found out so that the best light receiving angle of the convex lens is obtained. Tracking accuracy is high, and the monitoring method is simple. The monitoring module drives a convex lens connecting support and a supporting frame on the peripheral of the convex lens connecting support through a motor, so all-around rotation of the convex lens can be achieved. The diffusion sun tracking device is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of heater that can make with the device of solar motion, specifically a kind of focusing focal shift diffusion type sun tracker.
Background technology
Solar energy is a kind of natural harmless energy, be applied in every field by people gradually, obtained especially swift and violent development in solar heating system, well-known, only the convex lens in the guaranteed solar heating system are over against the sun, could obtain the highest sunshine utilization rate, because the rotation of the earth, 1 year four seasons spring, summer, autumn and winter, every light rise sunset, and the lighting angle of the sun is at every moment all changing, the luminous energy that only has the noon sensitive surface to collect in one day is maximum, and is most effective; And the solar heat collector of prior art all is to be fixed on some places, be used for the convex lens of focusing sunlight towards also fixing, convex lens can not all be over against the sun also, the utilization rate that therefore will guarantee sunshine just must keep convex lens at any time over against the sun, allow sunshine light at any time vertical irradiation to convex lens.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, easy to use, can Real-Time Monitoring position of sun, and can obtain the focusing focal shift diffusion type sun tracker of the best light angle information of lens.
In order to solve the problems of the technologies described above, focusing focal shift diffusion type sun tracker of the present utility model comprises convex lens, and the convex lens below is provided with the center light photosensitive elements that lays respectively at the orientation light-sensitive element in four quadrants of plane coordinates and be positioned at plane coordinates initial point place; The detection signal of each light-sensitive element exports a monitoring module to.
Described convex lens periphery is provided with housing, and described orientation light-sensitive element and center light photosensitive elements are positioned at the bottom of housing
Described center light photosensitive elements is arranged at the center of orientation light-sensitive element and is on the same level face with the orientation light-sensitive element.
Described center light photosensitive elements is arranged at the below of orientation light-sensitive element, and the initial point place of light-sensitive element boundary, four orientation is provided with loophole.
Be coated with one deck plated film on the surface of described convex lens.
The utility model has the advantages that:
1, the bottom of housing is provided with the orientation light-sensitive element that is positioned at four quadrants of plane coordinates and is positioned at center light photosensitive elements on four quadrant central shafts of plane coordinates, can search out best illumination orientation by orientation light-sensitive element and the center light photosensitive elements that arranges, thereby obtain the best light angle of convex lens, tracking accuracy is high, and monitor mode is simple;
2, by the bracing frame of monitoring module by motor-driven convex lens link and convex lens link periphery, can realize the omnibearing rotation of convex lens, simple in structure, easy to use.
Arrange thus, focusing focal shift diffusion type sun tracker of the present utility model can make the condenser lens of solar energy heat collector follow the variation that shines upon the position and change, and has obtained the highest sunshine utilization rate.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is that the plane distribution of each light-sensitive element of the utility model embodiment one and the system of light-sensitive element and monitoring module consist of schematic diagram;
Fig. 3 is the utility model embodiment two structural representations.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, focusing focal shift diffusion type sun tracker of the present utility model is described in further detail.
Embodiment one:
Such as Fig. 1, shown in Figure 2, focusing focal shift diffusion type sun tracker of the present utility model, comprise convex lens 1 and the housing 2 that is arranged on convex lens 1 periphery, the bottom of housing 2 is provided with the orientation light-sensitive element 3 that is positioned at four quadrants of plane coordinates and the center light photosensitive elements 4 that is positioned at plane coordinates initial point place, center light photosensitive elements 4 is on the same level face with orientation light-sensitive element 3, the direct irradiation of sunlight that convex lens 1 focus on is on center light photosensitive elements 4, the detection signal of each light-sensitive element exports monitoring module 9 to, judges the foundation of position of sun as monitoring module; Monitoring module can be exported control instruction accordingly, and the orientation of solar energy heat collector is adjusted.Be coated with the plated film that one deck can reduce the light transmission on the upper surface of convex lens 1, to reduce being heated of light-sensitive element.
Embodiment two:
As shown in Figure 3, this embodiment two with the difference of embodiment one is, center light photosensitive elements 4 is arranged at the below of orientation light-sensitive element 3, and the initial point place that four orientation light-sensitive elements have a common boundary is provided with loophole 10.
