Technical Field
[0001] The utility model relates to the technical field of farmland irrigation, in particular to a gravity water-saving and energy-saving irrigation system for paddy fields. Background Technique
[0002] Irrigation of paddy fields is a very important link in the process of rice cultivation. Reasonable irrigation management can significantly improve the yield and quality of rice. The irrigation management of paddy fields needs to be adjusted according to specific geographical, climatic and water resource conditions to achieve efficient and sustainable agricultural production.
[0003] In the existing paddy field irrigation, water generally directly irrigates through a U-shaped groove irrigation canal or a high-pressure pipeline. Due to the erosion of open weeds and the natural environment, the maintenance cost of the U-shaped groove irrigation canal is high, and the use and maintenance costs of the high-pressure pipeline are high. For the above reasons, we propose a gravity water-saving and energy-saving irrigation system for paddy fields. Content of the Utility Model

The connecting pipeline is connected to the water supply tank and the drainage tank through a water supply column. The inlet pump house is equipped with an inlet component connected to the connecting pipeline. Valves for controlling the opening and closing of the water supply column are installed inside the water supply tank and the drainage tank. A supplementary water pipe is connected between the water supply tank and the paddy field, and a return water pipe is connected between the drainage tank and the paddy field. The supplementary water pipe is higher than the bottom surface of the paddy field in the horizontal direction, and the return water pipe is lower than or flush with the bottom surface of the paddy field in the horizontal direction.
[0006] The further setting of the utility model is that a main outlet valve is installed on the main outlet pipe.
[0007] By adopting the above technical solution, when irrigating paddy fields, the main outlet valve is closed, the valve in the water supply tank is opened, the valve in the drainage tank is closed, and the water intake component in the water intake pump house extracts water from the external water channel, and then relies on the gravity of water to flow into the connecting pipeline. The connecting pipeline enters the water supply tank through the water supply column, and the water flow flows into the paddy field for irrigation relying on the height difference between the water replenishing pipe and the bottom surface of the paddy field. When the paddy field needs to be sunned, the main outlet valve is opened, the valve in the water supply tank is closed, the valve in the drainage tank is opened, and the water flow flows out of the paddy field relying on the height difference between the water return pipe and the bottom surface of the paddy field, and returns to the connecting pipeline through the water supply column, and is discharged into the external ditch through the main outlet pipe. Only the water intake component is provided in the water intake pump house in the entire irrigation system, and other water intake and drainage are realized by using the height difference of water pressure, which is convenient for maintenance, and the production cost and maintenance cost are low.
[0008] A further setting of the present utility model is that: the drainage end of the connecting pipeline is also communicated with a drainage pump house, a drainage pump is also installed inside the drainage pump house, and a water inlet pipe and a drainage pipe are communicated with the drainage pump.
[0009] By adopting the above technical solution, when the river water level is too high, closing the main outlet valve can prevent the water in the river from flowing back into the paddy field, and then start the drainage pump, use the water inlet pipe to extract the water in the connecting pipeline, and discharge it through the drainage pipe, achieving the effect of being able to irrigate when dry and drain when flooded, and ensuring the purpose of ensuring a bumper harvest of rice in case of drought or flood.
[0010] A further setting of the present utility model is that: a plurality of caissons are also communicated with the connecting pipeline.
[0011] By adopting the above technical solution, when the water flow circulates in the connecting pipeline and passes through the caisson, impurities in the water flow can be filtered, which is beneficial to reducing pipeline blockage.
[0012] A further setting of the present utility model is that: safety covers that can be opened are provided on the inner top walls of the water supply tank, the drainage tank and the caisson.

[0015] A further setting of the present utility model is that: water return holes are opened on the inner wall of the sedimentation tank, and the sedimentation tank is communicated with the paddy field through the water return holes.
[0016] By adopting the above technical solution, during the field drying process, when the water flows out of the paddy field relying on the height difference between the return water pipe and the bottom surface of the paddy field, it first flows through the return water holes to the sedimentation tank, which is beneficial to precipitate and filter the impurities carried in the water flow, and then flows through the return water pipe to the drainage tank and is discharged.
[0017] A further setting of the present utility model is that: the return water holes are flush with or higher than the return water pipe in the horizontal direction.
[0018] By adopting the above technical solution, relying on the height difference between the return water holes and the return water pipe, it is convenient for the water flow after sedimentation filtration in the sedimentation tank to flow back to the drainage tank and then be discharged.
[0019] A further setting of the present utility model is that: each paddy field is equipped with one water supply tank and one drainage tank.

[0022] By adopting the above technical solution, when the water inlet pump is started, it pumps water from the external ditch through the water inlet pipe, and then sends it to the water inlet pool through the water outlet pipe. The water in the water inlet pool flows to the connecting pipeline by its own gravity to irrigate the paddy field.

When irrigating the paddy field, the total water outlet valve is closed, the valve in the water supply tank is opened, the valve in the drainage tank is closed, the water inlet assembly in the water inlet pump house pumps water from the external water channel, and then flows to the connecting pipeline by the gravity of the water.

[0025] 2. When the water level in the river channel is too high, closing the main outlet valve can prevent the water in the river channel from flowing back into the paddy field. Then, start the drainage water pump, use the inlet pipe to pump the water in the connecting pipe, and discharge it through the drain pipe, achieving the effect of being able to irrigate when dry and drain when flooded, ensuring the goal of a bumper harvest of rice in both drought and flood. When the water level of the external river channel is lower than the height of the main outlet pipe, there is no need to start the drainage water pump 1. BRIEF DESCRIPTION OF THE DRAWINGS
