That is to say, a simple, practical and precise method of tracking the sun is the key to the application of solar energy. This new method is to use astronomy, solid geometry, physics and geographical knowledge to track the sun from the inherent law of motion of the earth to the sun. The retrieval shows that no similar method has been found. Patent Reports on Tracking Methods and Devices

Embodiment

[0054] Embodiment: (1) light concentrating application, taking the solar cooker as an example, the point 9 is the focus of the concave mirror 23 on the straight line (rod) 2. 32 is the shaft on the slant bar that separates on the bar 2, so that the concave mirror is connected to the shaft 32 by the bar 34 and can rotate freely; 27 is the counterweight of the concave mirror to facilitate the rotation of the driving gear 22; The bar, counterweight 27 links to each other by bar and bar 34. Operation process: (taking the northern hemisphere as an example, using the Chinese calendar as a reference)

[0055] 1. Record the noon moment in the geographical sense of this point 1 on the surface (making the base 21 uneven), and the feature is that the pole 24 has the shortest shadow in a day.

[0056] 2. Check the calendar on the second day to get the position of the day in the twenty-four solar terms. For example, on the 12th day of the summer solstice, point the pole 4 directly to the ...

Embodiment ( 4

[0075] A method of concentrating light in the solar thermal field, which is different from the way of using light sensors and electronic equipment to concentrate light in the existing solar concentrating method, including parallel lines of the earth's axis starting from a point on the earth's surface, and the plane mirror on the parallel line rotates with the sunlight With the rotation of one sidereal day a week, the angle between the normal of the plane mirror on the parallel line of the earth's axis and the reflected light changes with the angle between the sunlight and the parallel line of the earth's axis, so as to obtain the reflected light coincident with the parallel line of the earth's axis, and then use another plane mirror to Reflect sunlight to the surface of the object to be heated, and multiple (referring to 3 to 200) structures can complete the concentrating heating effect.

[0076] Explain how the first plane mirror 35 reflects sunlight to coincide with the paral...

Abstract

The sunlight tracking method and device is used in photovoltaic generation, photothermal generation, solar heat utilization and other solar energy utilization fields. The present invention is based on that after one straight line parallel to the earth axis is led out from some point on the ground, the angle of the connecting line between any point on the straight line and the sun to the straight line is the same as the angle between the sun beam and the earth axis and may be used in tracking sunlight. The present invention is simple and has low cost.

Description

technical field [0001] The invention relates to a method and equipment for tracking sunlight in the field of solar energy applications. The method and equipment are characterized by simplicity and accuracy, and the use of the method and equipment is beneficial to the universal application of solar energy resources. Background technique [0002] Solar energy is the most important resource for human beings, and it is the energy that human beings can completely rely on in the end. The application of solar energy is divided into three methods: photovoltaic power generation, photothermal power generation and photothermal utilization. Photovoltaic power generation uses solar panels to directly convert sunlight into electrical energy, while photothermal power generation and photothermal utilization both convert sunlight directly into heat energy for people to use. In the field of solar energy applications, there is a problem of how to increase the energy density of sunlight conveni...
