On the day of the military parade on September 3, as a driver of clean ground roads, Jia Lixin and his teammates will drive 22 pure electric zero-emission scrubbers independently developed and put the slate ground in front of Tiananmen Square once. Cleanly cleaned to ensure that the ground is not dusty when the officers and men are walking.
At 8 o'clock in the morning, two hours before the parade marching, 22 pure electric zero-emission scrubbers will be arranged in the shape of a reversed figure in the form of "the car is pressed in front of the car", from the east side of Tiananmen Square. At the beginning of the station, all the way to the west side of the viewing platform, after 15 minutes of cleaning, the ground reached a spotless effect.
Jia Lixin is an old driver who drives a scooter. He has been driving for more than 20 years and has participated in the road cleaning tasks of the 50th anniversary of the National Day, the 60th anniversary, and the 2008 Beijing Olympic Games. He said that the military parade is special and requires drivers to have high operational skills and psychological qualities. The ground cleaning task in front of Tiananmen Square must be completed at one time.
“A clean and zero failure is achieved once.†Jia Lixin said that in order to achieve the best cleaning results, he and his teammates practiced on a large road next to the Beijing World Camping Park every day, training for three hours in the morning and afternoon.
The most difficult part of training is to maintain a neat formation and achieve the best cleaning results. Jia Lixin told reporters: "We have to touch the car and train every day. The team formation training can't remember how many times it has been practiced. After more than a month of practice, it is now possible to keep the car at a constant speed of 2.5 meters and control at a speed of 5 , 6 kilometers."
According to Zhang Zhiqiang, head of the operation and management department of Beijing Environmental Sanitation Group, the driving directions of the 22 scrubbers are consistent with the military parade, moving from east to west at a constant speed, seamlessly grounding, covering the 50-meter width of the parade queue. After the washing of the washing machine, the stone pavement in front of Tiananmen Square reached “the road passed the road, the road saw the true colorâ€, and the dust stock dropped to 2 grams per square meter.
In order to make the officers and soldiers who are being read, the ground will not be dusty. The Beijing Environmental Sanitation Group independently developed the country's first 16-ton clean energy scrubber for the military parade.
Why can the water in the ground area be completely sucked up after the cleaning of the washing machine, and the effect of being spotless? According to Luo Wei, deputy general manager of Beijing Sanitation Group, the car has two 180-kilowatt motors, which can be used for work and walking. The high-pressure water gun in the car is sprayed to clean the ground, and a powerful suction pump can suck the ground sewage and garbage together.
A set of data indicates that the vehicle is in a leading position in the field of new energy technology: the vehicle can travel up to 360 kilometers, with a single charging cycle of no more than 3.5 hours; when performing road cleaning, the speed does not exceed 40 kilometers per hour. The maximum cruising range can exceed 200 kilometers, the continuous operation time can reach 7 hours, and the sweeping road width is 2.5 meters.
Through actual comparison, the R&D personnel also found that the pure electric scrubber has the characteristics of zero emission, zero pollution, low noise and low heat radiation, which not only reduces the noise of the conventional fuel vehicle by 15 decibels, but also the operating cost is only 35 for the fuel vehicle. %. The efficiency of the scrubber can be increased by 20% compared to ordinary fuel vehicles.
The main color of the vehicle body is gold, complemented by blue. Luo Wei said that in general, the annual operating cost of each fuel-gas sanitation vehicle is about 230,000 yuan, and the annual operating cost of the vehicle is only about 80,000 yuan, which saves money and is environmentally friendly.
Luo Wei introduced that using this pure electric scrubber for road operations, each car can reduce carbon dioxide emissions by 80 tons per year. This new car can be used for the first time in the military parade, reflecting the leading level of technology in China's new energy vehicles.
Concerned about surprises
The characteristic of the cup head square neck Bolt is that the head is made into a semicircular ball, and a section of square neck is made under the head. A section of square hole shall also be made on the connected part connected with this bolt. When the bolt is inserted into the connected part and the nut is screwed on, the bolt will not rotate because of the square neck. Its head is relatively smooth, and it is not easy to hook other objects.
