The "master-apprentice match" of ice and electricity

Guangming Daily Tianjin, January 21 (Reporters Liu Qian and Chen Jianqiang) On January 20, it was cold and snowy. The speed skating hall of Tianjin Jizhou National Ice Project Training Base is brightly lit, and the healthy posture of athletes from all over the world is speeding briskly on the ice. On the mountain not far from the venue, Wang Dongwei, the field team leader of the State Grid Tianjin Jizhou Xiaying Power Supply Service Center, and His apprentice Wang Meng are conducting a line inspection to ensure the safe and reliable power supply of the venue.

Tianjin Jizhou National Ice Project Training Base is more than 100 kilometers away from Beijing, and is an important training base for the national winter sports team to prepare for the Winter Olympics. The base covers a total area of 120,000 square meters and an ice surface of 17,600 square meters. "Our base has 2 ice hockey halls, 1 comprehensive training hall, and 1 speed skating hall, which has relatively high requirements for the reliability of electricity." Liu Haiying of tianjin Jizhou Winter Olympics training venue was introduced.

Among the routes that Wang Dongwei and Wang Meng are responsible for is the "lifeline" to this Winter Olympic training venue, which is about 14 kilometers long. "In order to ensure the safety of the line, three iron towers were built on the mountain during construction, and the two lines were set up with the tower one left and one right, which solved the problem of hillside crossing." But new problems followed, our patrol line 'drone' could not get close, there was a certain patrol blind spot. Wang Dongwei said.

After each UAV patrol of the route, Wang Dongwei and Wang Meng must continue to hike 4 kilometers to find a suitable location and look again with the telescope to be assured. When they parked their car in Kuliyu Village at the foot of the mountain, they often helped their fellow villagers deal with the problem of electricity in their homes, and as the days went on, they were familiar with the villagers.

"Thank you for the masks and disinfectants you sent." Uncle Zhang, who lives alone in the village, said with a smile. It turned out that in addition to carrying binoculars, thermometers, foot buckles, seat belts and other necessary tools, the two masters and apprentices also brought some of their own epidemic prevention items.

The two stepped on the undulating rocks, carefully checked the verticality of the pole, whether the pole pull line was loose, whether there was any rust at the junction of the wire and the foundation, properly tightened the bolts, used a machete to clean the debris around the pole, checked whether there was any abnormality in the distribution of sand and gravel around the pole, and checked the arc of the line with a telescope.

"Whenever we encounter bad weather, we must hurry up to carry out special patrols, and the most feared thing is that the landslide will cause the foundation to loosen and the pole to be skewed." Because the maintenance of power supply facilities on the mountain is very difficult, this line is also the power line of the Winter Olympic Training Venue, and the inspection work is as fine as possible, and the defects and hidden dangers are found and eliminated in advance, which can save a lot of equipment repair time. Wang Dongwei continued to move forward while patrolling the thin snow.

In the winter, the patrol people who cross the mountains and mountains generally bring less water, they put a small bottle of water in the pocket of the body, because they often eat and sleep in the wind, eat irregularly, the stomach will inevitably have problems, once they drink ice water, the stomach is more painful. There is a lot of gravel on the mountain path, the most feared is to step on the "mountain pit", sharp stones piled in the pit, buried by fluffy leaves, if you accidentally step into it, you may fall on your feet. Fortunately, there are few crazy weeds on the road, and the view is also wide, and there are no branches and leaves to cover it.

On snowy days, the mountain road is even more difficult to walk. Along the snow-covered mountain road, the two masters and apprentices came to the top of the mountain, which is the best place to observe. Wang Meng took out a thermometer, and Wang Dongwei took out a telescope and circled around the tower a few times, carefully observing whether the porcelain bottle and gold tools were intact. He casually picked up a stone and struck the tower, and when a few snow flakes fell, he judged whether the tower body was loose according to the vibration.

"Wang Ban is always very fast on mountain paths, and he said that patrols should not be carried out on horseback, and time should be spent on towers and lines." Wang Meng said.

The temperature on the mountain was several degrees lower than on the plain, and when they went up the mountain, they had to stomp their feet to keep warm, and the two of them sweated profusely after a round of inspection, took off their hard hats, and steamed their hair in the cold wind. Facing the wind and snow, on the way to patrol the power grid, they used another way to cheer for the Winter Olympic athletes.
