[0022] The utility model will be further described below in combination with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.

[0023] Referring to Figures 1 to 4 As shown in the utility model discloses an adjustable riverway side slope ecological dredging device, an embodiment, including riverway bottom plate 1, the riverway bottom plate is "U" character structure, the bottom surface of riverway bottom plate is provided with the silt groove 2, the silt groove both ends'side wall of riverway bottom plate is fixed with planting box 3, and the planting box bottom is provided with water-absorbing cotton 4, and the lower end of water-absorbing cotton is located in the silt groove end, and the silt groove is also provided with adjusting piece 5 for adjusting the position of sludge, and adjusting piece is used to shift sludge to both ends, and the riverway bottom plate bottom is also provided with the flow resistance plate 6. The flow resistance plate is arranged on the side where the water flow does not flow through the silt groove, and the flow resistance plate is integrally formed with the riverway bottom plate, so that the structural strength is guaranteed, and the top of the flow resistance plate is uniformly provided with a concave notch 16, so that the flow rate can be effectively reduced.

[0024] The riverway bottom plate is customized according to the shape of the riverway, specifically, it can be prepared according to the width and depth of the riverway, after preparation, the riverway is cut off, after cutting off, part excavation is carried out, the riverway bottom plate is hoisted to the excavation, and the gap between the riverway bottom and the riverway soil body is backfilled to ensure the effectiveness of the installation of the riverway bottom plate and avoid displacement caused by the scouring of river water on the gap. Of course, the riverway bottom plate can also be effectively fixed to the riverway bottom by anchor bolts.

[0025] After fixing, the installation can be completed, when using, the impurities and sludge in the riverway move to the riverway bottom plate along with the water flow, the moving rate of sludge can be effectively reduced by the flow resistance plate, and the sludge is deposited in the silt groove, the sludge is shifted to both ends of the silt groove by the adjusting piece, the planting box on both ends can degrade the sludge, and the new sludge continues to deposit, so that the sludge can be effectively improved. In the degradation process, the trace elements in the sludge are absorbed by the water-absorbing cotton to provide nutrient substances for the plants planted in the planting box, and the roots of the plants will extend into the sludge to effectively degrade the sludge after elongation.

[0026] The inner wall of the above-mentioned sludge accumulation tank along the water flow direction is provided as a slope surface 7, and the slope surface and the flow resistance plate are arranged on both sides of the sludge accumulation tank, and together form a structure of gentle slope and steep slope. Such structure is more conducive to guiding the sludge to deposit in the sludge accumulation tank, and the sludge is blocked by the gentle slope during flow, and then falls into the sludge accumulation tank due to the reduced flow speed, and the storage capacity of the sludge is effectively improved; a plurality of fiber ropes 8 are arranged on the slope surface, and the fiber ropes serve the purpose of attaching microorganisms, facilitating the degradation of the deposited sludge in the sludge accumulation tank by the microorganisms.

[0027] Specifically, the fiber ropes are fixed on the connecting rods 9, the connecting rods are arranged along the water flow direction, the upper end of the connecting rod is connected with the slope surface through the support frame 10, and the lower end is overlapped with the slope surface. The support frame suspends the connecting rod, so that the fiber ropes can fully contact with the sludge, improve the degradation effect, and also effectively reduce the resistance of the sludge sliding.
