“When we were exploring the application of solar power plants, I asked students what they wanted most to meet their living needs through solar energy. They answered the phone charging in unison.†led by Ding Qiang, a general technical teacher at the sixth middle school in Guandu District, led by solar energy research. The group's students started DIY DIY solar chargers.
Today, one year has passed, and the solar energy “full charge†they have created has been updated three times.
The third-generation solar charger is mainly composed of three components, a solar panel, a converter, plus a USB charging cable connected to 10 different interfaces. Turn on the switch, the indicator light emits white light, pick up the mobile phone, recording pen at hand, can find the suitable interface to charge.
Solar panels, batteries, circuit design, welding, all students themselves. Common digital products on the market can be charged with this "universal charge."
“We can replenish the power of mobile phones to the ground at any time. This is what students are most interested in. The interest is the best teacher.†So Ding Qiang and the students gathered together to search for information. Ding Qiang introduced that the principle of solar charger is to convert the energy of solar energy into electrical energy stored in the built-in battery of the solar mobile phone charger. When the mobile phone needs to be charged, the battery in the solar mobile phone charger will output the power to charge the mobile phone.
Last year, in March and April of last year, the first generation of Guanlizhong Solar Charger was released, but it has a flaw, that is, there is no charging display, the capacity is too small; last November, the students have been improved to create a second generation charger Due to the integration of lithium battery and solar panel, the temperature of the lithium battery is too high to shorten the lifespan during exposure. So, at the end of March of this year, it was updated again. The design of the body structure: solar panels, lithium batteries, self-contained, by a The data line connection, in this way, makes up for the shortcomings of the previous two generations and is also very convenient to use.
"Usually take out the sun in the sun, if necessary, plug in the USB charging cable on it. You see, has been shown in the charge." A student live demonstration, "Now, many people in our class like Use this magical thing."
The main type of Tape Measure is steel tape, followed by fiber tape, which is the tape that everyone often sees. Many people say it is a cloth ruler, and there is also a waist measurement ruler (tailor ruler/clothing ruler belong to this category). In southern China and Hong Kong, the tape measure is usually referred to as a soft ruler or a pull ruler. The material is PVC plastic and glass fiber, which can prevent the tape from being stretched during use.
