Trash holding mesh with variable mesh diameter for water taking open channel of nuclear power station
The invention belongs to the technical field of nuclear power station water taking opening trash holding meshes, and particularly relates to a trash holding mesh with a variable mesh diameter for a water taking open channel of a nuclear power station. The trash holding mesh comprises a support fixed in a water taking opening and provided with a lifting system, a fixed blocking mesh fixedly arranged on the support, and a movable blocking mesh moving up and down on the support through the lifting system; the fixed blocking mesh and the movable blocking mesh are arranged in an overlapped mode, a first grid is arranged in the fixed blocking mesh, a second grid is arranged in the movable blocking mesh, and drifting objects in the water flow in the water taking open channel are filtered by means of the fixed blocking mesh and the movable blocking mesh in sequence; by changing the position of the movable blocking mesh, the mesh diameter of the grid formed by overlapping the first grid and the second grid is changed; and according to a blocking mesh lifting and rapid laying device system, under the condition that foreign matter emergencies, rapid laying can be achieved through a vertical lifting opening and closing device, and the foreign matter is blocked rapidly. The trash holding mesh can adapt to different water flow and sewage working conditions, head loss is reduced, and the long-term operation cost of the nuclear power station is reduced.
本发明属于核电站取水口拦污网技术领域，具体涉及一种核电站取水明渠可变孔径拦污网。包括固定在取水口内的设有提升系统的支架，固定设置在支架上的固定拦网，还包括依靠提升系统在支架上进行上下移动的移动拦网；固定拦网和移动拦网重叠设置，固定拦网内设有第一网格，移动拦网内设有第二网格，取水明渠内的水流依次通过固定拦网和移动拦网对水流中的漂流物进行过滤；通过改变移动拦网的位置，使得第一网格和第二网格叠加后的网格的孔径发生改变；拦网提升及快速布放装置系统在异物突发的状况下，可采用垂直升降启闭装置实现快速布放并迅速对异物形成阻拦。本发明可适应不同的水流和污物工况，减少水头损失，降低了核电站长期运行费用。
