Detailed Description

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a water conservancy pipeline for hydraulic engineering, includes leading water pipe 1, is equipped with filter mechanism 2 and current-limiting mechanism 3 in leading water pipe 1, and filter mechanism 2 includes: the filter screen 4 is installed and connected with the water conduit 1; the rotating shaft 5 is rotationally connected with the water conduit 1; the impeller 6 is fixedly connected with the rotating shaft 5; the scraper 7 can rotate under the driving of the rotating shaft 5; the flow restriction mechanism 3 includes: and the baffles 8 are fixedly connected with the rotating shaft 5. Through the technical means, the service life of the device can be effectively prolonged.

Specifically, a sleeve 9 is connected to the end portion of the rotating shaft 5 in a sliding manner, an elastic element a10 is arranged in the sleeve 9, two ends of the elastic element a10 are fixedly connected with the sleeve 9 and the rotating shaft 5 respectively, the sleeve 9 is rotatably connected with the filter screen 4, and the sleeve 9 is fixedly connected with the scraper 7.
