Wear-resistant hydraulic engineering pipeline

The utility model discloses a wear-resistant water conservancy project pipeline. The device comprises a buffer adjusting mechanism and a sliding block, according to the utility model, the buffer mechanism is arranged in the fixed frame; water flow as it flows, the spoiler can be impacted; the spoilers drive the moving blocks to move towards the inner sides of the sliding grooves through the movable rods; the moving block presses the spring to deform and contract; the impact force at the upper end of the spoiler is absorbed; water flow can be buffered; the internal abrasion of the water conservancy project pipeline is reduced; an adjusting mechanism is arranged; rotary knob, the knob drives the screw rod to rotate; and the screw rod moves downwards to push an ejector block to move towards the lower end, so that a first folding rod and a second folding rod drive a moving block to move towards the left end through a push block, the moving block drives an inclination angle of a spoiler tobe changed through a mova
