Embodiment Construction

[0018] 1. Use a photoresistor whose resistance value decreases as the light intensity increases as the photosensitive element, and place it in a cuboid container with five sides closed and one side open as an optical signal acquisition unit. The four optical signal acquisition units are installed on the rotating parts of the solar energy utilization device, and the openings face four directions, east, west, north, south, respectively. The optical signal acquisition units with openings facing east and west are a group, and the optical signal acquisition units with openings facing south and north are a group. The electrical parameters of the photoresistors in these two groups should be very close. The two photoresistors are respectively connected in series with two fixed resistance and identical resistors, the power supply voltage is connected to the two series circuits through wires, and voltage division is generated at the voltage dividing point between the photoresistor and th...

Abstract

The present invention discloses a solar tracking system. The system uses four optical signal acquisition units as electrical signal sources to control a rotating part of a solar utilizing device to rotate toward an appointed direction. Each optical signal acquisition unit is a container which allows the entering of sunrays from only one direction through an opening, and other directions are sealed or do not allow the entering of sunrays because the container is downward when being arranged or because the container is blocked by other articles. A photosensitive element or a thermosensitive element is arranged inside the container. The openings of the four optical signal acquisition units are toward four directions which are east, west, south and north. The easterly opening and the westerly opening form a group and the southerly opening and the northerly opening form a group. The photosensitive element or the thermosensitive element is different in electrical state when receiving illumination with different intensities. The electrical state is converted into an electrical signal. The electrical signals of the two photosensitive elements or thermosensitive elements in each group are inputted into a comparison circuit to compare. The compared result is used for driving a rotating device to rotate toward the direction with comparatively intense illumination.

Description

technical field [0001] The invention relates to a sun tracking system, in particular to a device for driving a solar energy utilization device to face the sun, and belongs to the field of solar energy utilization and solar power generation. Background technique [0002] Energy is the material basis for the development of the national economy and the improvement of people's living standards. With the sustained and rapid growth of my country's economy, the environmental pollution of fossil energy has become more and more prominent. Pollution has become the main restrictive factor for my country's rapid economic development, and it is also the largest economic restrictive factor in the world. With the intensification of global warming, human use of fossil energy has become an environmental disaster. At this time, the use of various new energy sources, especially new energy sources such as nuclear energy, solar energy, and biomass energy, has become an urgent task for China. S...
