The utility model discloses an anti-blocking device of a water conservancy pre-buried pipeline, and relates to the technical field of pipeline anti-blocking devices, the anti-blocking device comprises a
pipe body, the inner side of the
pipe body is movably connected with a supporting mechanism, the right side of the inner cavity of the
pipe body is slidably connected with a filter plate, the middle part of the filter plate is fixedly connected with a driving mechanism, and the driving mechanism comprises a sliding rod; the middle of the periphery of the sliding rod is fixedly connected to the middle of a filter plate. According to the anti-blocking device of the water conservancy pre-buried pipeline, the drainage block, the sliding rod, the first compression spring, the limiting plate and the filter plate are matched, the pressure of
water flow and the elastic force of the compression spring are utilized, the filter plate reciprocates in the pipeline, the relative movement between the
water flow and the filter plate is enhanced, and the anti-blocking effect is improved. According to the
filter system, the washing and dispersion of
impurity particles are promoted, the self-cleaning of the filter plate is realized, the filtering efficiency is obviously improved, the accumulation of impurities on the filter plate is reduced, the service life of the
filter system is prolonged, and the frequency and cost of manual cleaning are reduced.
