[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figures 1-4 As shown, this utility model proposes a layered water diversion structure, including a main dam 1 and multi-level slope protection 2. The multi-level slope protection 2 is set on both sides of the main dam 1 and is cast integrally with it. During the casting process, a drainage channel 8 is reserved at the top of the main dam 1. Through the drainage channel 8, water from the water source can be diverted to the vicinity of farmland 7, facilitating subsequent irrigation of crops in farmland 7. Several outlet protective piers 6 are cast at the bottom of the drainage channel 8 and near its inner sidewall. The outlet protective piers 6 have drainage channels inside. Several steel bars are fixedly installed at the opening of the drainage channel near the side of the drainage channel 8. The steel bars form an intercepting grid structure, which can reduce the probability of foreign objects in the water flow entering the drainage channel. The main dam 1 and the multi-level slope protection 2 are jointly provided with a transverse water diversion channel. 9. One end of the transverse irrigation canal 9 is connected to the interior of the aforementioned drainage channel. A longitudinal irrigation canal 10 is provided inside the multi-level slope 2. The bottom end of the longitudinal irrigation canal 10 is connected to the interior of the matching transverse irrigation canal 9. During the high water season, when the water level inside the drainage canal 8 is high, the water pressure is sufficient to force the water in the drainage canal 8 into the longitudinal irrigation canal 10, and then the water is discharged from the top opening of the longitudinal drainage canal 8, and finally flows along the wall of the multi-level slope 2 into the farmland 7, avoiding erosion of the soil in the farmland 7. Several debris interception components 5 are fixedly installed inside the aforementioned drainage canal 8. The debris interception components 5 can intercept foreign objects (dead branches and leaves, domestic garbage, etc.) floating on the water surface, reducing the probability of foreign objects entering the farmland 7 with the water flow and avoiding pollution of the farmland 7 environment.

[0032] Further, the multi-stage revetment 2 is poured with a plurality of protective covers 4, which are arranged above the top openings of the matched longitudinal diversion channels 10, can prevent the sand, gravel, garbage and the like on the water channel dam from falling into the longitudinal diversion channels 10, and effectively improves the anti-clogging effect of the longitudinal diversion channels 10; the opening of the transverse diversion channel 9 away from the water outlet protective weir 6 is movably inserted with a sealing cement block 3, the sealing cement block 3 is provided with a penetrating opening 31, the wood pile 32 is movably inserted into the penetrating opening 31, and the bottom end of the wood pile 32 is inserted into the insertion slot 21 in the multi-stage revetment 2, so that the sealing cement block 3 can be stably sealed at the outlet end of the transverse diversion channel 9, and the wood pile 32 can be pulled out to take down the sealing cement block 3 from the water outlet, facilitating the disassembly and assembly of the sealing cement block 3.

[0033] Secondly, one of the outer side walls of the water outlet protective weir 6 is a slope structure, which faces the upstream direction of the water flow, and when the water flow washes the water outlet protective weir 6, the slope structure can play a guiding role to avoid hindering the flow of the water flow, and when the sludge at the bottom of the water flow adheres to the slope structure, compared with the plane structure, the amount of sludge accumulation can be reduced, and the effect of sludge flowing with the water flow can be improved.

[0034] Further, the trash blocking assembly 5 includes two symmetrically arranged cement seats 51, which are poured on the inner side wall of the drainage channel 8 and integrally formed with the main dam 1, and the two cement seats 51 in the same group are commonly inserted with a grid plate 54, and the side of the grid plate 54 facing the upstream of the water flow is fixedly installed with a U-shaped intercepting plate 55, when the foreign matters floating on the water surface move downstream with the water flow, the foreign matters can be intercepted by the grid plate 54, so that part of the foreign matters can be gathered at the U-shaped intercepting plate 55, the probability of foreign matter settlement is reduced, and a large amount of foreign matters entering the transverse diversion channel 9 and then being discharged into the farmland 7 is avoided; when most of the foreign matters are gathered at the U-shaped intercepting plate 55, the foreign matters can be conveniently salvaged, and the convenience of cleaning the foreign matters in the drainage channel 8 is improved.

[0035] Secondly, the cement seat 51 is provided with a limiting groove 52, and the two ends of the grid plate 54 away from each other are fixedly installed with a wooden board 53, the wooden board 53 is inserted into and connected with the matched limiting groove 52, so that the grid plate 54 can be firmly installed in the drainage channel 8; the wooden board 53 is pulled upward and disconnected from the limiting groove 52, so that the grid plate 54 can be taken out of the drainage channel 8, which facilitates the cleaning and maintenance of the grid plate 54 and effectively improves the durability thereof.

[0036] In this embodiment, first, the water in the water source is drained to the vicinity of the farmland 7 through the drainage ditch 8. In the wet season, the outlet port of the transverse water diversion ditch 9 is blocked using the sealing cement block 3 to prevent the water from flowing out of the outlet port and causing soil erosion in the farmland 7. At this time, the water flows into the transverse water diversion ditch 9 from the water outlet protection baffle 6. Since the water level in the drainage ditch 8 is higher than the height of the top opening of the longitudinal water diversion ditch 10, the water in the drainage ditch 8 can be pressed into the longitudinal water diversion ditch 10, so that the water flows out of the top opening of the longitudinal water diversion ditch 10 and flows along the multi-level slope protection wall 2 to the farmland. When the water level in the drainage ditch 8 is lower than the height of the top opening of the longitudinal water diversion ditch 10 in the dry season, the sealing cement block 3 is pulled out, so that the water flows directly out of the outlet port of the transverse water diversion ditch 9. At this time, the water flow is small and will flow along the multi-level slope protection wall 2 to the farmland 7. The layered water diversion structure can prevent the water from flowing quickly into the farmland 7 and avoid soil erosion in the farmland 7, reducing the risk of soil erosion in the farmland 7.

[0037] In the process of water flowing along the drainage ditch 8, the foreign matter (branches, leaves, household garbage, etc.) floating on the top layer of the water flow flows with the water flow. When the foreign matter floats from the upstream to the downstream, it is intercepted by the grid plate 54 and collected by the U-shaped interception plate 55. This can reduce the amount of foreign matter settling on the water bottom, reduce the probability of blocking the transverse water diversion ditch 9, and reduce the amount of foreign matter flowing into the farmland 7, avoiding pollution of the internal environment of the farmland 7 and protecting the ecological balance of the farmland 7. The layered water diversion structure can prevent the water from flowing quickly into the farmland 7, avoid soil erosion in the farmland 7, solve the problem of soil erosion, and effectively reduce the risk of damage to the farmland.
