The reporter learned from the 701 heavy ship 702 yesterday that a few clear float boats designed by the institute for the Three Gorges reservoir area, "Three Gorges Qinghuang No. 2" and "Three Gorges Qinghuang No. 3", were successively in Wuzhou Ezhou. Everbright shipbuilding groundwater. After the end of the year, the four clearing boats designed for the Three Gorges reservoir area will be fully utilized. Among them, "Three Gorges Qinghuang No. 2" is currently the largest clearing float in the world, and is completely designed and manufactured by China.
The latest clearing boat, such as "water robot"
The Three Gorges clearing floats, designed by the Yangtze Three Gorges Group and invested in 701, have a total of four ships. Ships 1 and 4 were delivered in 2007 and 2012. It is understood that the 2nd and 3rd ships are more novel in propulsion design, using advanced full-rotation rudder propellers, which are more flexible in operation and are very suitable for clearing and floating in narrow areas of the reservoir area.
Among them, the No. 2 ship is the largest, 65 meters long and 15 meters wide. The catamaran type, all-welded steel structure, regardless of the captain, main engine power, gross tonnage, ship capacity and ship garbage disposal capacity, all exceed the "Three Gorges Blooming" No. 1" is currently the world's largest type of drifting boat.
The unique design of the left and right side of the ship's clearing robot makes the boat look like a robot floating on the water.
According to the research and development personnel of the institute, the front end of the hull of the No. 2 ship is equipped with a Great Wall mesh chain collection bag, and the ship can be collected automatically to collect the floating objects. More than 3 meters long on the right chord of the ship, the long arm of the dragonfly floats, and the surrounding floating objects can be collected into the bag by rotation.
The left chord is equipped with a grab to specifically collect heavy garbage. Through the design of the drifting device, the floating debris on the water surface will be pushed to a corner and collected. All the floating objects are collected into the cleaning bag and then automatically transferred from the bow to the stern through the belt conveyor, and then automatically transported to other boats for transport.
The drifting boat has saved more than one billion yuan
In 2003, the Three Gorges Dam closed the gate and impounded water. At the same time, “Gaoxia Out of Pinghuâ€, a large number of broken branches and leaves, crop straws, animal carcasses and plastic foam, wrapped in large and small stumps, gathered into pieces, merged into a belt, Down the river, it is almost equal to the Three Gorges Dam... Especially in the flood season from May to October every year, a large amount of floating garbage will accumulate in the water surface of the reservoir area. At first, it was a small fishing boat that was manually salvaged, but it was difficult to deal with it effectively.
In 2003, the State Council leaders instructed: "The floating debris of the Three Gorges of the Yangtze River not only directly threatens the safe operation of the Three Gorges Project, but also seriously affects shipping, fishing, tourism, and destroys the natural landscape, and must be determined to govern."
It is understood that the first time that the 701 was involved in the design of the Three Gorges clearing float began in 2003, and for the first time, the Yangtze Three Gorges Group Company designed a 49-meter-long mechanized No. 1 clearing float. This is China's first multi-functional bleaching ship independently developed and with independent intellectual property rights.
After the ship was delivered in March 2007, it completely changed the situation that the small floating objects in front of the Three Gorges Dam and the floats of the ship lock chambers were manually cleared by small fishing boats. After years of clear drifting application of the Three Gorges section, it not only eliminates the safety hazards of the Three Gorges Dam, but also effectively protects the basic functions of flood control, power generation and navigation of the Three Gorges Project.
Among them, the total accumulated savings exceeded 1.4 billion yuan. The floating matter handled each year can generate 20,000 tons of calories and directly increase power generation by 950 million kWh. At the same time, it also improved the cleanliness of the reservoir area and improved the water quality of residents along the Yangtze River in the middle and lower reaches of the Yangtze River.
In 2011, the ship won the first prize of Hubei Science and Technology Progress Award. At present, the scientific and technological achievements have been successfully promoted to the Yellow River Xiaoxia, Fujian Shuikou and other hydropower station clearing and bleaching projects.
