[0033] In summary, for the anti-blocking trash rack used for water conservancy management, the trash interception net 2 can intercept impurities in the water flow. Then, the double-output shaft motor 9 drives the two driving worms 10 to rotate synchronously, thereby driving the two driven worm wheels 7 to rotate, driving the driving lead screw 6 to rotate and driving the guide sleeve 15 to rise. During the upward sliding process, the cleaning scraper 5 can clean and introduce the impurities intercepted on the outer surface of the trash interception net 2 into the interior of the cleaning basket 4. After the impurities fall to the inner bottom of the cleaning basket 4, by continuing to slide upward, the driven gear 17 slides to a position meshing with the driving gear 16. Then, the driving motor 12 drives the driving gear 16 to rotate, driving the pushing auger 14 to rotate, pushing the impurities at the inner bottom of the cleaning basket 4 towards the discharge port, so that the impurities are discharged, realizing automatic cleaning. The driving lead screw 6 is arranged on the back of the trash interception net 2, so that the water flow passing through the driving lead screw 6 is clean water, preventing impurities from affecting the operation of the driving lead screw 6.
