Problems solved by technology

Single-axis tracking can only track the change of one of the azimuth and altitude angles. Generally, it tracks the change of the azimuth angle, and has the disadvantage of low tracking accuracy.
Dual-axis tracking can track changes in azimuth and altitude at the same time, but has the disadvantage of low flexibility

Embodiment Construction

[0016] The present invention is described in more detail below by means of examples, but the following examples are only illustrative, and the protection scope of the present invention is not limited by these examples.

[0017] like figure 1 As shown, a three-rod sun tracking device includes a photoelectric detector 1, a loading platform 2, a universal ball running track 3, a universal ball 4, an electric push rod 5, a supporting platform 6 and a signal processor 7.

[0018] The photodetector 1 is fixed on the loading platform 2 . like figure 2 As shown, the photodetector 1 includes a light shield 8 and a four-quadrant detector 9 . The shading cover 8 is a hollow cylinder, the side wall is sealed and opaque, and the top center has a circular hole. The four-quadrant detector 9 is placed in the light shield 8 and is located at the bottom center of the light shield. The radius of the photosensitive surface of the four-quadrant detector 9 is larger than the radius of the roun...

Abstract

The invention provides a solar tracker. The solar tracker is characterized in that the solar tracker comprises a photoelectric detector, a loading platform, universal ball running tracks, universal balls, electric putters, a supporting platform and a signal processor, wherein the photoelectric detector is fixed in the center of the surface of the loading platform; the back of the loading platformis provided with three universal ball running tracks which are arranged at 120 degrees and have the same length, the extended lines of the three universal ball running tracks intersect at a point; the loading platform is supported by three electric putters, one end of each electric putter is embedded in each universal ball running track through each universal ball and can slide on the universal ball running track, the other end is fixed on the supporting platform; the axis of each electric putter is vertical to the surface of the supporting platform, the corresponding fixing points of the three electric putters on the supporting platform constitute a regular triangle; and the inside of the supporting platform is loaded with the signal processor. The solar tracker has high loading capability and can be loaded with a large-area solar panel; the solar tracker has small inertia and friction in the adjustment process, the device stability can be increased, the service life of the solar tracker can be prolonged; and the solar tracker has the advantages of high precision and flexibility, and is easy in realization.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and in particular relates to a three-rod solar tracking device. Background technique [0002] As the global energy crisis intensifies, it becomes more and more necessary to develop and utilize new energy sources. Solar energy has become a research hotspot due to its advantages of environmental protection and sustainable utilization. Due to the shortcomings of low luminous energy density, intermittent, and constantly changing spatial distribution of solar energy, its utilization rate is very low. To improve the utilization rate of solar energy, the absorption efficiency of solar energy must be improved. The sun tracking device provides an effective way to improve the absorption efficiency of solar energy. [0003] At present, there are mainly two ways of solar tracking: photoelectric tracking and solar trajectory tracking. The photoelectric tracking method tracks the sun by detecting th...
