[0005] The present application provides a water diversion device for water conservancy projects, including a filter box and a pipeline. A through groove is opened at the top end of the filter box, and the pipeline passes through the through groove. A control mechanism for controlling the forward and backward movement of the pipeline is arranged in the through groove. An inclined and rotatable filter screen is arranged on one inner wall of the filter box. A discharge pipe is arranged at the bottom end of one outer wall of the filter box. A pick-and-place opening is opened on the other outer wall of the filter box, and a shielding plate is arranged in the pick-and-place opening. A partition plate is arranged on the bottom inner wall of the filter box, and a plurality of filter holes are opened in the upper middle part of the partition plate.
[0006] Specifically, the control mechanism includes a placement groove opened on one side of the through groove. A screw rod with a waterproof motor is arranged in the placement groove. A nut is threadedly engaged with the screw rod. A circular ring is arranged on one side of the nut. The pipeline passes through the circular ring and is connected to the circular ring.
[0007] Specifically, a waterproof telescopic rod is arranged on the other inner wall of the filter box, and the moving end of the waterproof telescopic rod is movably connected to one side of the filter screen.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] The drained water enters the filter box through the pipeline, and then the control mechanism controls the nozzle part of the pipeline to move back and forth in the filter box. During the back-and-forth movement, the water passes through the filter screen, and the impurities stay on the filter screen and automatically slide down under the inclined filter screen. Moreover, during the back-and-forth movement of the pipeline, it is possible to avoid the water flow impacting a certain part of the filter screen for a long time, prevent the impurities from passing through the filter screen with the water flow, and also prevent damage to the filter screen. After the impurities accumulate and increase, the filter screen folds downwards, the filter screen contacts the top of the partition board, one side of the filter screen separates from the inner wall on the other side of the filter box, and the impurities fall from the gap. Some of the water located in the left space gradually rises, and some of the water flows into the right space through the filter holes on the partition board, avoiding some water staying in the left space. Open the baffle and take out the impurities from the access opening. The filtered water is discharged to the next process through the discharge pipe. By filtering the impurities in the water, it is possible to avoid polluting the soil and prevent affecting the planting of crops. Brief Description of the Drawings
