Description

Technical Field

[0001] The utility model relates to the technical field of water diversion and irrigation for farmland in mountainous areas, in particular to an ecological farmland water diversion and irrigation structure in mountainous areas. Background Art

[0002] The mountainous areas of the Loess Plateau are characterized by water scarcity, large seasonal variations in runoff water levels, harsh natural conditions, low winter temperatures, and easily frozen rivers. Accessibility is poor, and commonly used water extraction methods, such as reservoirs, dams, and river diversion, are labor-intensive, high-maintenance, and have low returns on investment, making them difficult to implement. Therefore, a water extraction irrigation system in the mountainous areas of the Loess Plateau, utilizing low-pollution shallow runoff initially purified by the mountain's natural ecology, could be developed to efficiently and effectively utilize the region's limited surface water resources, improve agricultural productivity, and have significant implications for rural agricultural development and the protection of natural resources. Summary of the Invention

The backflush water pump is fixedly connected to the backflush pipe, and the backflush pipe is fixedly connected to the nozzle. The water guide plate is fixedly connected to the sewage pump, and the sewage pump is fixedly connected to the sewage pump, and the sewage pump is fixedly connected to the water guide plate.

[0010] The utility model provides a water diversion and irrigation structure for ecological farmland in mountainous areas, which has the following beneficial effects:

[0011] Through its structural design, this device excavates the riverbed in the mountainous area according to the actual terrain conditions of the undercurrent distribution. The bottom of the riverbed is impermeable bedrock. Then, a water diversion guide plate and an overflow dam are installed on the riverbed. The water diversion guide plate guides the undercurrent to the position of the water intake. The excavation range at the water intake is backfilled with a filter layer. The filter layer can filter sediment and drain water. When the filter layer filters sediment for a long time, some debris will remain in the filter layer and cause blockage, affecting the time for the filter layer to filter the undercurrent. At this time, it is only necessary to temporarily close the water storage pump and turn on the backwash pump and the sewage pump. The backwash pump pumps the water in the water collection channel to the backwash pipe distributed in a grid pattern on the outside of the water collection channel and sprays it through the nozzle. The grid-shaped backwash pipe will not block the position of the water inlet. The water sprayed by the nozzle will flush the sediment and other impurities blocked in the filter layer back to the surface of the filter layer. At this time, the sewage pump uses the sewage pipe to pump the upper surface of the filter layer The impurities flushed out on the surface are pumped to the gap between the water guide plate and the riverbed, and will not remain on the filter layer. After the filter layer is cleaned, the backwash water pump and the sewage pump are turned off to divert water normally. The filter layer is arranged obliquely to facilitate the underground flow to quickly pass through the water inlet and converge into the water collection channel. The water storage pump will collect the filtered water in the water collection channel along the water storage pipe to the high-level water storage tank at a high place, and the water resources are stored by the high-level water storage tank. When the farmland needs irrigation, the irrigation unit located at the lower place is opened, and the water in the high-level water storage tank will flow into the irrigation unit along the pipe under the action of gravity to irrigate the farmland in the mountainous area. The utility model makes full use of the underground flow of rainwater in the mountainous area for agricultural irrigation, solves the problems of lack of water sources in the mountainous area and difficulty in irrigating farmland, and at the same time uses the filter layer buried in the riverbed to filter and purify the underground flow of low-pollution rivers in the mountainous area, which is used for irrigation of ecological farmland, thereby improving the industrial structure and productivity of farmland.

The bottom of the riverbed 2 is an impermeable bedrock to prevent the undercurrent from seeping in. Then, a water diversion guide plate 1 and an overflow dam 3 are installed on the riverbed. The water diversion guide plate 1 guides the undercurrent to the position of the water intake. The trumpet-shaped water diversion guide plate 1 can better guide the undercurrent. The excavation range at the water intake is backfilled with a filter layer 4. The three layers of filter layers 4 are, from top to bottom, a gravel layer, a crushed stone layer, and a fine pebble layer. The particles of any layer are not allowed to pass through the pores of the adjacent coarser layer, which can better To filter soil and drain water, when the filter layer 4 filters sediment for a long time, some debris will remain in the filter layer 4 and cause blockage, affecting the time for the filter layer 4 to filter the underflow.
