Abstract: A pre-interception device includes an input portion for a fluid to flow in, an output portion for the fluid to flow out, a plurality of diversion flow channels and a plurality of interception portions. Each diversion flow channel is in communication with the output portion and the input portion, is configured to provide turning guidance for flow of the fluid, and has a fluid lift section. The interception portions are configured to form a turbulent flow field in the fluid. The turbulent flow field can have foreign objects flowing through the diversion flow channel be captured. Accordingly, a filtering effect is achieved based on physical properties of the foreign objects. When the pre-interception device is additionally combined with a filter net to form a filtering system, the burden on the filter net is further alleviated, hence extending a service life of the filter net and reducing costs.
