Recently, Zhang Yongjun, the head of Double Chuang Studio of Changsha County Vocational School of Changsha County, ushered in the "Double Happy Gate". The projects he developed "universal nut openings" and "ceiling -style photovoltaic roads" were also won the fifth China (Shanghai) International Invention and Innovation Exhibition Gold Award.

Zhang Yongjun, 51, was called "Edison in the education industry" by his colleagues. He was good at pondering and loved to invent. He has made various small inventions since 1997. Today, the studio is a variety of medals, certificates and "inventions".

"In the past, the strong nuts were pressed with external forces, which would cause crushing fruit and more laborious. And the universal nut open operator brought people another way to open it. It can protect the flesh inside. Open all kinds of nuts of various sizes. "Zhang Yongjun proudly showed the use of the" universal nut open operator "to reporters, put a pine on the opening, gently stretched, the shell shed, revealing the complete fruit, this The whole process is 1 second.

This type of opening is shaped like a tiger's head, one end is smooth, and two dull blade attached to the other end. As long as the nut is stuck on the knife's mouth, the knife mouth is squeezed into the fruit shell, and then you can use the thimble to open it.

The nuts are delicious, but the shell is hard, so that the "food" people taste less convenient. Zhang Yongjun, who likes to eat nuts, found that the functions of various nuts openings on the market are relatively single, and most of them can only open one or two nuts, so the idea of ​​making a "comprehensive" fruit opening.

At the end of 2018, Zhang Yongjun began to develop the "Universal Nut Operation" and has experienced three iteration updates. "The first generation of the opening is long for fruit kernels, the appearance is not beautiful, and the second generation has improved, but it is not very convenient to use. The third generation has undergone qualitative changes. All kinds of nuts. "Zhang Yongjun believes that the invention cannot stop because of obtaining a certificate. Instead, it must make his invention perfect and enter millions of households to truly facilitate people's lives.

"This is the most missionary and social responsibility project in my invention. It has created a new photovoltaic application scenario." In Changsha County Vocational Double Innovation Studio, Zhang Yongjun introduced the "ceiling -style photovoltaic road" model, Blooming in the eyes.

"The emergence of ceiling -style photovoltaic roads is an innovation in the construction of the road itself." Speaking of the advantage of this invention, he said, "This invention has paid equal power generation and traffic, and the sun will not directly expose the road, rain will not be directly exposed, rainy rain will be exposed, and rain will not be directly exposed. Snow will not soak the pavement, thereby alleviating the aging of the pavement and achieving the purpose of optimizing the transportation environment; in high -cold areas, you can use devices to melt ice and snow to reduce hidden dangers of traffic; To reduce energy consumption.

Zhang Yongjun hopes that the "ceiling -style photovoltaic road" will land as soon as possible to benefit the society. Power can be generated by about 1.2 trillion degrees a year. At present, the country's electricity consumption is 8.35 trillion kWh, 30%of which are clean energy power generation. The powerful power generation of photovoltaic power generation itself helps to achieve decarbon. "

On June 20, the 5th China (Shanghai) International Invention Innovation Exhibition kicked off online. 672 innovative technologies and achievements from the autonomous regions of various provinces and cities and Romania, Indonesia, Iran, Thailand, Vietnam, Poland, the Philippines, Malaysia and other countries participated in the exhibition. Innovation achievements involve advanced manufacturing, artificial intelligence, biomedicine, new materials, new energy, energy saving and environmental protection and other fields, covering various invention innovations close to daily life. The three sectors such as the district are exhibited.
