Waterproof drainage device of hydraulic engineering construction

The utility model discloses a belong to hydraulic engineering technical field, specifically be a waterproof drainage device of hydraulic engineering construction, include the motor and be equipped with the casing of water inlet with the outlet, through setting up the pivot at the casing inner chamber, the all sides of pivot are connected with the pipe perpendicularly, the pipe is connected on thepivot surface along the pivot axis direction is even, the pipe helps making the good debris of some pliabilities winding in the water, the great debris access to plant of quality in the water is avoided to the water inlet that open side down, the water inlet further reduces the debris in the water with the filter screen of outlet department, avoid debris to arouse that the device blocks up, life -span is low, influence the problem of engineering time, stopping through opening of control motor, making the pipe rotatory round the axis, the surperficial dirt of brush cleaning shells inner wall, aspiration pump pass throu
