At present, people's needs are not only to solve the problem of food and clothing, but to improve the quality of life. However, the environmental problems brought about by rapid economic development have begun to affect people's quality of life. On the other hand, with the depletion of traditional energy resources such as oil, natural gas, and coal, people have begun to devote themselves to the development and utilization of new energy. As a clean and sustainable energy source, solar energy has huge market and application prospects.

At present, the country is committed to building a well-off society in an all-round way. In order to enrich the spiritual and civilized life of the people, the construction of large-scale sports venues is in the ascendant in China, such as the Bird's Nest and the National Grand Theater. Similar to the construction of large stadiums, while promoting the development of sports and improving the physical fitness of the people, its energy consumption is also huge. But at the same time, we have noticed that these stadiums often have a large building area, and their building roofs can be used for solar power generation. At present, solar roofs at home and abroad are statically fixed with solar panels on the roof. Since the altitude and azimuth of the sun change with the seasons and time of day, the solar energy cannot be used efficiently.

In China, such as Ordos Stadium, Nantong Stadium, and Xiamen Olympic Center, the viewing conditions and comfort have been greatly improved by adopting different forms of roof technology. But at the same time, we have noticed that these large-span roofs with opening and closing functions are often unable to install solar panels due to technical limitations, thus greatly reducing the effective ways of solar power generation.

If the advanced expandable structure building technology can be combined with the solar tracking system and utilized, on the one hand, the span structure roof can be opened and closed freely to meet the requirements of the building's internal functions and comfort; at the same time, solar energy can be used to generate electricity efficiently , To a certain extent, make up for the excessive energy consumption of large public buildings.

The working process of the self-facing solar energy utilization system with expandable roof of the present invention includes four processes of solar roof deployment, solar panel tracking, solar panel reset and solar roof retraction, specifically as follows:

Solar roof unfolding process: see Figure 1, take a simple 4 solar roof panels as an example, the whole device is controlled by the lower control circuit 7, turn on the "expand" switch (see Figure 10 for detailed circuit diagram), stepping motor 7-1 drive device Start to work, the rotation of the conveyor belt 4-1 drives the solar roof panels to unfold, the front rollers of the outer frame 1 roll down the slope, as shown in Figure 2, the roof panel is slightly inclined from the horizontal, as shown in Figure 3, the front rollers 1-3 move to the guide rail 4 The top is "supported", and the motor continues to drive. At this time, the roof panel will be propped up, as shown in Figure 4. When it is propped up in place, the protrusions of the rear outer frame roller 1-3 (the front part does not) touch the middle contact switch 4-2-1, the control circuit 7 sends out a "stop" signal, and the motor stops.

Solar panel tracking process: switch to the "sunshine" switch, the tracking system circuit is connected and starts to work. The four photoresistors 3-1 on the four sides of the solar panel 3 convert the light signal into a sensitive electrical signal, and the tracking system controls the motor built in the inner and outer frames of the roof to achieve accurate "sun-facing". As the sun moves, the solar panel always Perpendicular to sunlight to maintain maximum power generation efficiency, see Figure 5.

Solar panel reset process: When the work is over, switch to the "reset" switch, see Figure 10, the tracking system circuit is disconnected, and the power supply 7-4 directly controls the motors of the inner and outer frames to start reset (due to the fact that the roof is actually working due to the fixed position of the building , the direction in which the solar panel rotates toward the sun is certain, so the power supply 7-4 can be directly reversed to allow the motor to rotate in the opposite direction to achieve reset), and the inner frame C-shaped switch 2-2 built in the frame can control the solar panel and the frame in the same position. When level, the motor stops. The switch shaft 1-1-3 and 1-1-2 of the C-shaped switch are fixed, and then fixed with the solar panel 3, and the three rotate together, as shown in Figure 7, the sliding head slides on the C-shaped sheet 1-1-1, the two Connected to the reset circuit, keep the reset circuit connected, the motor rotates, and the reset action is performed; see Figure 8, when the slider moves to the opening of the C-shaped piece, the slider and the C-shaped piece are disconnected, and the circuit is disconnected. At this time, the side axis of the solar panel Parallel to the side axis of the inner frame to complete the reset action. Inner frame 2 is the same as outer frame 1.

Solar roof retraction process: Next, the switch is switched to the "closed" switch, as shown in Figure 10, the control circuit 7 sends out a "reverse" signal, and the stepper motor 7-1 reversely drives the solar roof panel to retract, and when it is in place, it passes through another Contact switch 4-2-2, the control circuit sends a "stop" signal to stop the motor, and the work ends.
