Relevant departments are working on Tiananmen Square As well as 253 Kehua lamps and more than 6,000 light sources on Chang’an Street, a comprehensive “physical examination” was carried out. In the next two months or so, the staff will “beautify” all the lamps, including cleaning the lamp balls, repainting the lamp poles, etc. More importantly, it is necessary to test all the cables of Hua Deng, and plan to upgrade the single lamp monitoring system of Hua Deng.
Ask to the end: How to check the “physical examination” of Huadeng?
What do you mean by the Huadeng single lamp monitoring system just mentioned? What technical ways are needed to clean and maintain Hua Deng? Hua Deng “physical examination”, how to check, what are the difficulties? Why are the 253-based street lights on Tiananmen Square and Chang’an Street called Huadeng? How is it different from ordinary street lights? Let’s get to the bottom of it.
What is the difference between a Chinese lamp and an ordinary street lamp?
Standing beside Tiananmen Square and Chang’an Street, the lanterns have long become a unique landscape. What are the parts of the lantern? How is it different from ordinary street lights?
The lanterns around Tiananmen Square and Chang’an Avenue consist of three parts. They are the lamp ball lamp cover at the top, the lamp pole at the middle and the base at the bottom.
Song Xiaolong, Secretary of the Party Branch of Hua Deng Class: There are two kinds of lanterns, one is 9 balls with an octagonal pavilion in the middle, we call it the nine-ball lotus lantern, and the other is 13 balls, all of which are glass lamp balls , we call it 13-ball cotton ball lamp, 110-base 9-ball lotus lamp, 143-base 13-ball cotton ball lamp, a total of 253 Kehua lamps.
Song Xiaolong, Secretary of the Party Branch of Hua Deng Class: Our lanterns are not exactly the same as ordinary street lamps, because the lanterns not only take into account the lighting of the roads on Chang’an Street, but also take into account the role of landscape lighting. Since it was built in 1959, it has left a figure of Hua Deng in this important historical event and important historical moment in our country.
What steps and processes are included in the “Physical Examination” of Huadeng?
In order to ensure the safe and stable operation of Hua Deng in Tiananmen Square and Chang’an Street, the Hua Deng class will carry out a cleaning and maintenance work for Hua Deng every year. What are the steps and procedures for the Hua Deng physical examination? Come and listen to the secrets from the front-line staff.
Song Xiaolong, Secretary of the Party Branch of Hua Deng Class: After the summary of Hua Deng people of all dynasties, as well as the research on the standardized operation process. We have also compiled a special professional instruction book for the cleaning of lamps and lanterns. This instruction book is divided into 6 big steps and 37 small steps, starting from parking, setting up traffic command and lamp cleaning and maintenance, including line maintenance, etc., 6 big steps 37 Xiaobu has been very complete, so that our personnel can pay attention to safe production and ensure that there is no accident in safe production during the cleaning of Huadeng.
With such a detailed operation manual, how will the staff complete the cleaning and maintenance of the Hua Deng next?
Chen Chunguang, monitor of the lantern class:< /span> One is day shift and the other is night shift. During the day shift, the main thing is to ensure that the equipment is in good condition. The light pole is not crooked, the light ball is not crooked, and special patrols in special weather, strong winds, hail, etc. are encountered. There is also a night shift, everyone will understand the night shift very well, repair the light bulbs, and ensure the lighting rate of the lights.
Chen Chunguang, monitor of the lantern class:< /span>On the other hand, it is technical skills, because there are lanterns, street lamps, and ordinary street lamps. The types of lamps are more complicated. There may be those that need tall cars, those that need bright cars, and those that require us to use our feet. It is necessary to buckle and climb the light pole, so the skills must be relatively complete, and it can cope with various situations that occur in daily life.
Which high-tech equipment is silently “guarding” the lights?
For the physical examination of Hua Deng, skilled workers are far from enough. What high-tech equipment is also silently guarding the safe and stable operation of Hua Deng?
Song Xiaolong, Secretary of the Party Branch of Hua Deng Class:In the daily maintenance work of Hua Deng, we have two main equipments. The first is the single lamp monitoring system of Hua Deng, because Hua Deng According to its different functions and functions, the light sources it is equipped with vary from 17 to 41 on each lamp pole. Then, our single-lamp monitoring system can be used in the case of any light source failure on any base and a Chinese lamp, our background will immediately know which bulb has a problem, and the maintenance personnel will be notified after receiving a notification. Repair the first time after, so as to ensure that the lights are always bright and bright.
Song, Secretary of the Party Branch of Hua Deng ClassXiaolong:The second system is that there is an electronic sign on Huadeng, we call it Huadeng’s electronic account. There is a passive emission chip inside this sign, and this chip is linked with the background. Through the handset, I can see where the upper-level power supply of this CEVA light comes from, where does the lower-level power supply of this CEVA light go, including the model of the cable and the year the cable was installed, etc. Some related The technical data and technical information will be in this sign, which is the important technical achievements of our Hua Deng maintenance and cleaning.
Hua Deng physical examination will be conducted once a year. To ensure that the cleaning and maintenance work is completed before the National Day every year, the construction period is basically between May and September each year. Now is the hottest time in Beijing, and the maintenance of Huadeng must be staggered during the rush hour. The 14 staff of the Huadeng class must accurately complete the cleaning and maintenance of the Huadeng between 10:00 and 16:00, the hottest day of the day. . Take off the light bulb, transfer, rinse, wipe, check the light source and wiring, replace, install, these operations should be done in one go.
Chen Chunguang, monitor of the lantern class:< /span>After the traffic flow on Chang’an Avenue came up, we began to “give way to the people”. From 10:00 in the morning to 4:00 in the afternoon, just in time for the hottest period, that is, our cleaning season every year, basically runs through the dog days, one day does not fall, one day is not wasted, and this cleaning and maintenance is carried out throughout the dog days. .
What upgrades and improvements have the 63-year-old Hua Deng experienced?
The 253 Kehua lanterns built in 1959 are now 63 years old. They stand beside Tiananmen Square and Chang’an Street, witnessing the continuous prosperity of the new China. Over the past 60 years, has Hua Deng changed? It should be said that the appearance has not changed much, but the heart has continued to improve.
Take the light source as an example, incandescent lamps were first used, then high-pressure mercury lamps, high-pressure sodium lamps, and now electromagnetic induction induction lamps. Everyone feels that it is getting brighter and brighter, but the energy consumption is getting lower and lower, and the lifespan and reliability of the light source are also improving.
