TECHNICAL FIELD
[0001] The utility model relates to sewage treatment equipment field especially relates to a steel wire rope grid clear fishing harrow that adapts to big flow velocity. BACKGROUND
[0002] The grid is usually woven or composed of steel wire rope. The steel wire rope grid has high strength and toughness and can withstand the impact of high flow rate water flow. The mesh size can be designed according to the size of the intercepted sundries, for example, at the water inlet of a sewage treatment plant, the grid mesh for intercepting larger garbage can be relatively large, and if smaller sundries are intercepted, the mesh will be designed to be smaller, the sundries are fished up from the grid and transferred to the designated collection area.
