On April 18......, the reporter learned from the Municipal Engineering Management Office of Guanshan Lake District that the five sets of remotely controlled intelligent flood control manhole covers independently researched and transformed have been put into use in five low-lying and water-prone points in Guanshan Lake District, which is the first innovation in flood control work in Guiyang City.
That night, there was significant precipitation and strong convective weather process in Gui'an, Guiyang, and the Municipal Engineering Management Office of Guanshanhu District checked the water accumulation at the intersection of Bihai South Road and Xingzhu West Road through the remote monitoring system, and then opened the intelligent flood control manhole cover for drainage through remote operation. After a while, the stagnant water on the road surface was drained in time.
The staff of the district municipal office debugs the manhole cover
According to reports, when extreme weather such as strong winds, heavy rains, and hail occur, the rainwater on the road will carry many leaves, branches, garbage and debris into the inlet well, which will affect the drainage efficiency of the inlet well, resulting in water accumulation, affecting the travel of citizens, and there are potential safety hazards.
"In order to effectively respond to heavy rain and other weather, realize remote opening of manhole covers, rapid drainage, and ensure the safety of people's lives and property, in February this year, the district municipal office began to research, design, and install intelligent manhole covers that can be remotely monitored and controlled. Tang Zhenglin, director of the District Municipal Engineering Management Office, introduced.
The staff of the district municipal office installed manhole covers at low-lying water-prone points in the West Second Ring Road
In the specific work, the relevant personnel of the Road and Bridge Drainage Maintenance Department of the District Municipal Department, the Street Lamp Bright Maintenance Department and other departments gave full play to the technical advantages of their respective departments in signal control, mechanical equipment, etc., carried out design and production, research and transformation, and completed the installation in early April after passing effective experiments.
It is reported that the manhole cover in operation, will be through remote 4G Internet of Things video surveillance, real-time understanding of the local rain conditions, targeted automatic early warning, the use of waterproof grade of IP67, low-voltage 24 volt DC hydraulic electric active power assist device to support the opening of the manhole cover, the use of 4G remote control switch automatic opening and closing, etc. to achieve intelligent rapid drainage, effectively improve the rapidity, safety and reliability of drainage emergency operations.
The staff of the District Municipal Affairs Department checked the low-lying and water-prone points at the intersection of Bihai South Road and Xingzhu West Road in real time through the mobile phone APP
At the intersection of Bihai South Road and Xingzhu West Road, the reporter saw that the remote control intelligent flood control manhole cover is significantly different from the previous water inlet manhole cover, and the overall color is red and rectangular.
At the intersection of Bihai South Road and Xingzhu West Road, the terrain is low-lying and prone to water accumulation, the red manhole cover is the remote control intelligent flood control inlet manhole cover, and the yellow manhole cover is the ordinary technical defense transformation inlet manhole cover
At the scene, Dan Xiaojie, the person in charge of the mechanical equipment and materials section of the District Municipal Department, demonstrated the opening process of the manhole cover by operating the mobile phone APP, when the manhole cover received the signal, it was slowly lifted up through the device, and at the same time, the red warning light at the lower end of the manhole cover began to flash, reminding drivers and pedestrians to pay attention to safety.
"In the past, it took us 20 to 60 minutes to manually uncover the manhole cover after the water accumulation point appeared, but now, after we find the water through the background video surveillance system, we only need to operate remotely, and we can remotely open the manhole cover in tens of seconds, and at the same time, we can also remotely shout to remind the public to pay attention to safety. Dan Xiaojie introduced.
At the intersection of Bihai South Road and Xingzhu West Road, the low-lying and water-prone points are opened by remote intelligent control of the flood control manhole cover
Next, after the stable operation of the manhole cover system, the district municipal engineering management office will install intelligent manhole covers at multiple water-prone points, drop-down grooves, underground passages and other locations in the Guanshan Lake area to ensure the safety of people's lives and property, and provide Guanshan Lake experience for municipal flood control and drainage.
