DETAILED DESCRIPTION

[0018] The utility model is described in detail according to the accompanying drawings of the specification.

[0019] like Figure 1 , Figure 2 As shown, the ecological buffer zone used for river water management includes ecological slope protection located on both sides of the river water body.

[0020] Among them, a cross beam 6 is provided between the ecological slope protection 1 on both sides. Slide blocks 9 are provided at both ends of the cross beam 6, and longitudinal thread sleeves are provided on the slide blocks 9. The ecological slope protection 2 is provided with a bracket 3 and a longitudinal screw 5 matched with the longitudinal thread sleeve is supported by the bracket 3. The bracket 3 is provided with a driving device 4 connected to the upper end of the longitudinal screw 5. The number of the cross beams 6 is multiple, and they are arranged at intervals along the length direction of the ecological slope protection 2.

[0021] A plurality of suspension ropes 7 are evenly fixed to the bottom surface of the cross beam 6 along the length direction, and the lower end of the suspension rope 7 is connected to a retractable carrier frame 8, and the retractable carrier frame 8 is provided with a microbial filler for treating the water body. In this embodiment, the retractable carrier frame 8 is composed of a plurality of bearing rings arranged at intervals from top to bottom and a plurality of connecting ropes connected between two adjacent bearing rings. The uppermost bearing ring is connected and fixed to the lower end of the suspension rope 7. A bearing cavity is provided in the bearing ring, and micropores are provided on the bearing ring. A plurality of adsorption claws are further provided on the outer surface of the bearing ring for adsorbing viscous substances in the water body and utilizing microorganisms for degradation nearby. A transverse sinking pit 11 corresponding to the cross beam 6 is provided at the bottom of the river channel, and each retractable carrier frame 8 can be sunk in the transverse sinking pit 11.

[0022] The ecological slope protection 2 is a stepped slope protection and a plurality of grooves are evenly arranged on the upper surface of each step, and a prefabricated nutrient soil block 10 is arranged in the groove, and a vegetation 1 is arranged on the prefabricated nutrient soil block 10. In this embodiment, the vegetation 1 is designed as a submerged plant area and an emergent plant area from bottom to top along the stepped slope protection. A water level meter is arranged at the ecological slope protection 2.

[0023] Working principle:

[0024] 1. Before work, microbial fillers are loaded into each carrying ring of the retractable carrier frame 8, and each retractable carrier frame 8 is fixed to the lower surface of the cross beam body 6.

[0025] 2. Start the driving device to drive the longitudinal screw 5 to rotate, thereby driving the cross beam 6 downward, so that each retractable carrier frame 8 is immersed in the water body. When water flows through, the microbial filler in the carrying ring enters the water body through the micropores and then goes away with the water body, which greatly reduces the blind spot of the microbial filler.

[0026] 3. Use a water level gauge to monitor the water level in real time. When the water level rises, the driving device drives the cross beam 6 upward. When the water level drops, it drives the cross beam 6 downward, so that the retractable carrier frame 8 is always located in the middle of the water body to ensure the treatment effect on the water body.

[0027] The above is a detailed description of the embodiments of the utility model, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the invention of the utility model should still fall within the scope of this patent.
