Technical Field
[0001] The utility model relates to the technical field of terraced fields, in particular to a water collecting and draining device for terraced fields. Background Art
[0002] Terraces are fields with strip-shaped steps or wavy sections built along the contour lines on hilly slopes. Terraces have good ventilation and light transmission conditions, which are conducive to crop growth and the accumulation of nutrients. According to the different slopes of the fields, there are horizontal terraces, slope terraces, compound terraces, etc. When building terraces, it is advisable to retain the topsoil. After the terraces are built, agricultural farming measures such as deep plowing, increasing the application of organic fertilizers, and planting appropriate pioneer crops are used to accelerate soil maturation and improve soil fertility.
[0003] At present, terrace irrigation and drainage usually adopt natural flow and simple artificial ditches. This method not only has low water resource utilization rate, but also when encountering extreme weather such as heavy rain, the water in the terrace will quickly accumulate and increase the pressure on the ridges. At this time, if the water in the terrace cannot be discharged in time, it is easy to collapse the ridges, thereby causing soil erosion and damaging crops. Utility Model Content

A terraced field water collection and drainage device is provided. The specific technical scheme is as follows:
[0005] A terrace water collection and drainage device comprises a terrace body, a plurality of water pipes installed on the terrace body and used for draining water in an upper terrace to a lower terrace, and a drainage mechanism installed on the terrace body and used for discharging excess water in the terrace into an external water storage facility during extreme weather such as heavy rain. The drainage mechanism comprises a drainage component and a control component. The drainage component comprises a plurality of drainage pipes installed in the terrace body, and a connecting pipe fixed between one ends of the plurality of drainage pipes for connecting to an external water storage facility. The control component comprises an electric valve fixed in the drainage pipe, and a liquid level switch fixed on the outer wall of the water pipe for automatically opening the electric valve after the water level in the terrace rises rapidly. Filters are provided in the water inlet ends of the water pipe and the drainage pipe.
[0006] By adopting the above technical solution, in extreme weather conditions, if the water intake of the terrace is greater than the drainage volume of the aqueduct, the water level of the terrace will rise. At this time, the control component will automatically start the emergency drainage mode and quickly drain the excess water from the terrace area through the drainage component.
[0007] Optionally, a plurality of ridges are provided on the top of the terrace body, and the water pipes, drainage pipes and connecting pipes are fixedly arranged in the ridges. A farmland planting area for planting crops is formed between the top of the terrace body and the plurality of ridges. A water collection trough for collecting rainwater and irrigation water is provided in the farmland planting area, and the water inlet ends of the water pipes and drainage pipes are located in the water collection trough.
[0008] By adopting the above technical solution, rainwater and irrigation water from the previous terrace will flow into the water collection tank when it rains, and people can plant crops such as rice in the water collection tank in the farmland planting area.
[0009] Optionally, a solar panel for supplying power to the electric valve and the liquid level switch is provided on the top of the water conduit, and a bracket for raising and fixing the solar panel is fixedly provided on the top of the drainage end of the water conduit.
[0010] By adopting the above technical solution, the bracket can fix the solar panel and raise the solar panel so that the water flowing down from the terraced fields is not easy to contact the solar panel.
[0011] Optionally, a limit hole is provided on the top of the water inlet end of the water pipe and the drain pipe, the filter screen is movably arranged in the corresponding limit hole, a grip ring for people to hold is fixed on the top of the filter screen, and the water inlet end of the water pipe and the drain pipe is provided with a screen cleaning component, the screen cleaning component includes a fixing rod fixed on the top of the water inlet end of the water pipe and the drain pipe, and a plurality of bristles fixed on one end of the fixing rod and inserted in the mesh of the filter screen.
[0012] By adopting the above technical solution, the filter net can filter foreign matter in the water, so that the inside of the water pipe and other components are not easily blocked by foreign matter. People can quickly dredge and clean the filter net through the net cleaning component.
[0013] In summary, the present invention has at least one of the following beneficial effects:
[0014] 1. Through the setting of water pipes, water in the upper terraces can be diverted to the lower terraces to irrigate the crops in the terraces layer by layer. In extreme weather conditions such as heavy rain, if the water intake of the terraces is greater than the drainage volume of the water pipes, the water level of the terraces will rise. At this time, the control component will automatically start the emergency drainage mode, and the excess water resources will be quickly discharged from the terrace area through the drainage component to avoid disasters such as soil erosion and terrace collapse.
[0015] 2. The setting of drainage mechanism can enhance the ability of terraces to cope with extreme weather. The drainage component can send the discharged water into external water storage facilities to collect and utilize the water discharged from the terraces, thereby reducing the waste of water resources. Automatic drainage and collection in extreme weather can improve the efficiency and stability of water collection and drainage in terraces. The filter net can filter foreign matter in the water, making it difficult for the inside of components such as water pipes to be blocked by foreign matter. People can quickly dredge and clean the filter net through the net cleaning component, which is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS
