Shi Yubo works with his solar lawn mower
In the exhibition hall of Tongtan West District, Longtan District, Jilin City, a weird-looking weeder was placed inside, and a large solar panel was placed on the machine. “This is a solar lawn mower made by Shi Yubo. In addition, he also has other small inventions. This man is lovable.†Nearby neighbors have praised Shi Yubo’s craft.
Homemade solar lawn mower
Shi Yubo, 55 years old, was once a technical worker of instrumentation and electrical automation. Everyone called him a veteran stone. Laoshi is now working at a property repair station in a community near the intersection of Longshan Road and Maolin Street in Longtan District, Jilin City.
Shi Yubo came to the property in 2006 and is responsible for the cleaning of the community. In the same year, a fuel lawn mower was introduced into the plot. This lawn mower was very noisy when working and was very disturbing. After more than one year of use, the cost of maintenance and fuel consumption of the weeder is high, the cost is increasing, and it is not environmentally friendly.
Due to the fact that the former was a skilled worker, Shi Yubo was usually willing to study and refine some small inventions. He not only wanted to reduce the cost of the weed cutter but also wanted to reduce pollution. So he thought of the solar energy resources and planned to make a solar lawn mower himself.
In 2008, Shi Yubo bought a discarded weeder chassis from the waste recycling station, and then bought a solar panel and associated controllers. He repaired the used chassis and painted it again. After the solar panels and lawn mower controls and transmissions were installed, he began to try it out.
It takes a year to improve the machine
During the trial, the problem also appeared. "The machine is fluent when idle, but with the load on the lawn, horsepower is not enough." Shi Yubo increased the power of the motor, increased the horsepower, but still can not achieve the desired results. In order to increase the speed of the weed cutter, Shi Yubo replaced the auxiliary bearing of the transmission mechanism, reduced the auxiliary bearing, and increased the main bearing, thereby increasing the speed of the auxiliary bearing and speeding up the speed of the cutting knife. Mowing efficiency.
After this solar lawnmower was completely improved, the time of one year has passed. The cost of the entire process, Shi Yubo, is completely at his own expense. No unit is worth a penny and a total of more than 10,000 yuan has been spent. When the improved weed cutter is put into use, not only the weeding effect is improved, but also the noise is much smaller than that of the fuel mower.
Later, this weeder was also put on display in the exhibition hall of the residential property and other workers were encouraged to study the small invention of energy efficiency.
Going out of school to love invention
It is understood that Shi Yubo deliberately went to Beijing to learn solar photovoltaic inverter technology in 2001 because of his love for technology. At the same time, he still does not forget to continue to research some small inventions.
"I found it difficult to remove the tyres when I changed the tyres of the sanitation vehicle, so I wanted to be a tool to assist in the manual retrieval of the tyres." Shi Yubo said that he bought scrap iron and made a meter more than a meter from the ground. Highly hollow iron frame, the tire can be fixed in midair by the iron frame, the tire has a fulcrum in the mid-air, can turn, and then he made a small flat shovel, insert the flat shovel into the middle of the tire and the tire, turn the tire, the tire It came out at once.
Friends praise their family
Lifting Shi Yubo, Wang Jian, who works in a residential property, is full of praise. “Old Stone is very diligent, likes to research some small inventions, and it is very practical. At present, we have purchased a number of solar panels, we must promote solar lawn mowers and use them within the community.†Wang Jian said Shi Yubo’s family conditions are very general and his body is not Good, but very keen on technical research, people are very enthusiastic.
"As long as there is a big event, he only needs to know that if you don't speak, he will help you for the first time," Wang Jian said.
Although his colleagues highly praise Shi Yubo, Wei Guiyun, his wife, complains about her husband. "In 2001, my daughter was still in school. I didn't earn a lot. He was not in good health, so the living conditions were very poor at that time. But he also learned technology to make inventions. I was very uncomfortable in my heart." Wei Guiyun said, although she did not Opposing her husband, there are still some complaints in my heart.
"Now that living conditions are better, and his body can eat, I do not oppose it. I hope he will be happy." Wei Guiyun said. (Reporter Wen Yue)
This diameter of this series glass bead is two or three times bigger than regular beads. The surface part beyond paints is higher than regular beads; hence the reflectivity of road marking has been increased, especially in rainy, foggy areas.
The diameter is 850-1400mm (20-14mesh) with ≥80% of roundness. The special coating on the surface of glass bead can improve the adhesion between paint and glass beads, thus the longevity can be increased.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
