From underwater to lake to the air, there are "black technology" everywhere

On the lake, no one cleaned the boat to "remove" floating garbage; under the water, no one detected the "observation" biological group; in the air, the drone sprayed the biological bacteria back and forth; outside the atmosphere, there were satellite remote sensing detection of cyanobacteria concentration ... In the Jianghan District Machine Dangzi Lake, the introduction of many "black technology" is making lake maintenance management work more "digital intelligence".

Floating objects gathered in the lower air outlet, and the garbage automatic collector "breaks the question"

The machine Dangzi Lake is located at the intersection of Xinhua Road and Construction Avenue in Jianghan District. The water area is about 10 hectares. At the beginning of the 20th century, due to urban development, real estate developers took a large amount of soil and formed a depression, so they were named "machine swing".

On the morning of June 16th, a reporter from the Yangtze River Daily came to the machine Dangzi Lake and saw a circular bucket -shaped device that was swallowing the lake in the northwest corner of the lake. The filter in the device is equipped with floating garbage such as fallen leaves, and a white drainage pipe is also extended in the underwater part.

"This is the" surface garbage automatic collector ', which is used for floating garbage dedicated to the air outlet of the lake. "Pan Ruijing, director of the Lake Management Institute of Jianghan District, said that due to the influence of the seasonal wind direction, the floating objects on the lake will gather in large quantities at the lower air outlet and manually clean up artificially It's time -consuming and laborious.

The automatic collector of the water surface uses the water pressure difference, which can inhale the floating objects with a range of 20 or 30 square meters around, and then discharge clean water. In addition to fallen leaves and white garbage, the equipment can also filter the oil film -shaped atmospheric sinking objects floating on the water, solving the inconvenience and tedious problems of traditional artificial salvage atmosphere.

"I come to collect this filter basket at seven o'clock in the morning, and then collect it every one or two hours from an interval. As long as it is opened at night, it can work all the time before the garbage is full, which is very easy to use." Xiucai is cleaning the garbage in the filter.

The reporter saw that the replacement of the filter was very convenient. Sun Xiucai took out a small remote control and pressed the closing button. Immediately afterwards, he stretched out the long rod with hooks to arrest and retract the filter, poured the garbage into the woven bag on the side, and took only a few minutes of operation.

No one cleaning the ship "one -click" to clean the lake surface garbage

On the lake, the reporter saw a green and white boat being cruising. The head of the ship is two sheet filters, which are opened in an eight -shaped shape. A small camera is also equipped at the front of the boat, and a large filter is hung in the middle of the hull. This is an unmanned clean ship.

Compared with the fixed surface garbage automatic collector, unmanned clean ships can be freely sailed on the lake, and even the gaps of the plank that are difficult to enter can be flexibly in and out without leaving dead corners.

According to reports, there are two main types of action modes of unmanned cleaning ships. One is the remote control of artificial machines and is suitable for accurate area floating objects. District cruise, suitable for daily lake cleanup and maintenance.

On the staff's tablet, the reporter saw the real -time screen from the camera from an unmanned cleaning ship. In addition, it could display the action trajectory and the relevant data of water quality monitoring.

At the smart terminal dedicated to unmanned cleaning ships, the equipment managers told reporters that from seven o'clock in the morning, unattended ships work 8 to 10 hours a day, and each battery life can reach four to five hours.

In addition to stopping the unmanned cleansing ship, the smart pier can also charge it. According to the staff, when the unmanned cleaning boat completes the task or the power is insufficient, it will automatically return to the charging. It is fully charged for about 3 to 4 hours. After full power, it will continue to complete the task, "Just like the sweeping robot used at home." When the garbage in the filter is collected, the unmanned clean ship will return to the dock. At this time, the staff needs to clean up the garbage.

Pan Ruijing told reporters that traditional artificial cleaning of lakes requires two people. One person rows and one person can do it. When it encounters heavy rain or high temperature, it cannot work, and unattended ships can achieve uninterrupted work for 24 hours and safer.

Candida water is focusing on prevention, satellite remote sensing helps to accurately detect water bodies

The detection of aquatic creatures and water quality is an important task for lake maintenance management.

In the machine Dangzi Lake, an underwater detection unmanned ship with a camera can penetrate the bottom of the lake. It is suitable for the requirements for exploration, monitoring, and inspection of a variety of waters and complex terrain. With it, the maintenance personnel can know the growth of water and grass and fish on the shore or on the ship. And structure, maintain the ecological balance of the lake.

In order to control the healthy lake ecology, the maintenance personnel need to put biological bacteria to the lake. At this time, the drone with the function of the medicine is sent in handy. It can not only replace the artificial rapidly putting the pharmacy, but also identify the lake waters through the high -definition camera to transmit various data to the ground to form basic information.

Candida water is a problem in the lake governance community. "Once out of the outbreak, the cyanoscopy will increase with geometric multiple." Pan Ruijing said that governing cyanobacteria water requires a lot of manpower and material resources, so the industry often attaches great importance to prevention.

Through satellite remote sensing images and water quality detection data, the content of the lake's overall cyanoba is inspectedFor regions, prevent work is more accurate and efficient.

Pan Ruijing told reporters that the robot Dangzi, as the first lake intelligent operation and maintenance demonstration base in Jianghan District, will also introduce drone cutting machines in the future, which is specifically used to deal with the rapid growth of sinking water plants.EssenceIn addition, the Jianghan District Lake Management Institute will also improve the intelligent operation and maintenance software system, connect the smart water platform, and further promote the development of smart lake management and construction in the direction of dataization and intelligence.
