[0048] A method for constructing an ecological ditch suitable for mountain villages, which is applicable to the above-mentioned ecological ditch suitable for mountain villages, comprises the following steps:

[0049] S1: The ecological ditch maintains a natural curved shape and integrates with the mountain village landscape. The slope and width are determined. The slope is 1%-3%, and the width is 1-3 meters. It adopts a layered structure, including a sedimentation area 11, a filtration area 13, and an aquatic plant growth area, as well as a curved area 12 that connects the sedimentation area 11 and the filtration area 13 and is set based on the landform;

[0050] S2: The water flows through the curved area 12 to drive the fan plate 23 to generate a force, thereby driving the first rotating ring 22 to rotate through the fan plate 23, and then driving the auger 21 and the rotating rod 2 to rotate, completing the collection of sediments. At the same time, the first chain 54 and the second chain 57 drive a group of circular filter screens 41 to rotate, so that the filter material inside the filter screens is more fully in contact with the water flow, thereby increasing the service life of the filter material;

[0051] S3: Natural gravel and sand are used as filter materials, and native aquatic plants suitable for the local area are planted to purify water quality, remove pollutants in the water, conserve water and soil, reduce rainwater erosion, provide biological habitats, and enrich biodiversity.

[0052] Working principle: The curved area 12 is set according to the special landform of the mountain village to connect the sedimentation area 11 and the filtration area 13, providing power for the sediment collection in the sedimentation area 11 and the flipping of the filtration material in the filtration area 13, so as to make its function better, and no additional power source is used. It is driven by water power and is suitable for the wild of mountain villages, and conforms to its special landform and terrain, with low cost and high operation efficiency. In addition, blocking dams can be appropriately set at the front end of the sedimentation area 11 and the filtration area 13 according to the situation, and its height can be adjusted according to the rainy season to ensure that the flow rate of water in the sedimentation area 11 and the filtration area 13 is not too fast. The sedimentation tank 14 is set in an arc shape, which can make the sediment impurities move along the water flow and enter the collection tank better, and the water flows through the outer side of the inner wall of the curved area 12, thereby A set of fan plates 23 are driven to rotate, and then the first rotating ring 22 and the auger 21 are driven to rotate through the fan plates 23. The L tube 24 is fixed by the fixing ring 25, so that the impurity sediment in the gathering tank 16 is driven by the auger 21 to rise into the L tube 24 and be discharged through it, and the sediment is transported to the outlet end of the L tube 24 through the auger 21, and the water flow is filtered out from the filter plate 3, and the impurities are accumulated on one side of the filter plate 3 and enter the discharge pipe 31. By opening the valve 32 regularly, the impurities are discharged through the discharge pipe 31, thereby completing the collection of the sediment at the bottom of the channel body 1, and the transmission rod 4 is driven to rotate through the transmission unit, and then the circular filter screen 41 is driven to rotate, so that the contact between the filter material inside the circular filter screen 41 and the water flow is more uniform, and the overall use frequency of the filter material is the same, and the flow is smooth. In order to increase the service life of the filter material and improve the quality of water purification, the first chain 54 is driven by the rotating rod 2 to drive the first shaft 51 to rotate, so that the first shaft 51 drives the bevel gear 55 on the transmission rod 4, and the second chain 57 is driven by the second sprocket 56 on the transmission rod 4, so that a group of transmission rods 4 are driven to rotate through a group of second sprockets 56, and then the circular filter screen 41 is driven to rotate through the transmission rod 4. Because the first chain 54 is transmitted in a curved shape, its position needs to be limited by the limiting sprocket 53, and the first rod 61 and the second rod 63 are connected by the connecting rod 62, and the first rod 61 and the circular filter screen 41 are fixed. By taking a pair of T-shaped blocks 6 and placing them in a pair of T-shaped grooves, the connecting rod 62 and the second rod 63 are fixed, and through the first The second rod 63 drives the first rod 61 to rotate, and then drives the circular filter 41 to rotate. Through the arrangement of the first square slider 65 and the second square slider 66, the second rod 63 can drive the first rod 61 to rotate through the connecting rod 62, and it is convenient to disassemble it. When the connecting rod 62 is separated from the limitation of the second rod 63, the circular filter 41 is taken out by taking out a pair of T-shaped blocks 6, and then the circular filter 41 is taken out, and the circular filter 41 is opened through the side cover 67, and then the filter material inside it is replaced or flushed. This method increases the efficiency of replacing the filter material and avoids destroying the natural ecology of the bottom part of the channel body 1. Through a group of high and low cross-arranged guide plates 7, the sediment can be made to move downward more efficiently under the guidance of the guide plates 7 when flowing with the water flow.Thus, the sediment collection effect is improved. The establishment of the guide block 72 can make the water flow, under the guidance of the guide block 72, align with the fan plate 23, so that the operating efficiency of the fan plate 23 is increased. The rotation of the rotating rod 2 can drive the animals to avoid damaging the device on the one hand, and on the other hand, play the role of power generation. Then, the controller 81 controls the electric valve 32 to open regularly, and the sediment impurities are discharged through the discharge pipe 31.
