Abstract
Description
Technical Field
[0001] This utility model is a simple farmland water diversion device, which uses the siphon principle to introduce ditch water into farmland. Background Technology
[0002] Existing equipment typically uses electric water pumps to pump water from elevated canals across dams and into lower-lying farmland. However, it's crucial to consider that not all farmland has convenient access to electricity. Using large storage batteries would be prohibitively expensive for farmers, as the cost of purchasing both batteries and pumps would be a burden. Furthermore, operating electrically powered equipment near water is inherently dangerous, posing significant safety concerns. Additionally, batteries and pumps are generally heavy, requiring vehicles for long-distance transport and potentially damaging roadbeds. Summary of the Invention
[0003] To address the problems of power shortage, high cost, safety risks, and inconvenience in mobility in existing technologies, this utility model provides a simple farmland irrigation device that utilizes the siphon principle. Water is manually poured into the device, and the air inside the device is expelled by alternately opening and closing the two valves at the top, triggering the siphon phenomenon. This allows water in the high-level water channel to flow automatically and continuously to the farmland, thus achieving farmland irrigation without consuming any electricity.
[0004] The technical solution adopted by this utility model to solve its technical problem is: a simple farmland irrigation device utilizing the siphon principle, comprising an exhaust pipe, an intake pipe, and three valves. The intake pipe is divided into three parts: a connecting pipe parallel to the ground, a shorter inlet pipe, and a longer outlet pipe. The inlet and outlet pipes are connected to the two ends of the connecting pipe via 90-degree bends, respectively. The exhaust pipe is connected to the middle of the connecting pipe via a three-way T-joint. A valve is installed at the upper and lower ends of the exhaust pipe, designated as the first and second valves, respectively. A valve is installed at the lower end of the outlet pipe, designated as the third valve. These structures together form a siphon pipe with good airtightness.
[0005] The aforementioned simple farmland irrigation device has valves with strict airtightness. When the first and second valves are closed simultaneously, neither water nor air can enter the exhaust pipe. When the second valve is closed and the third valve is opened, the irrigation pipe has the necessary physical conditions to form a siphon effect.
[0006] The advantages of this invention are that it achieves fully automatic and continuous water diversion from high to low points solely through the siphon effect, requiring no electricity and offering high safety, energy efficiency, and environmental friendliness. Its simple and lightweight structure and low cost make it suitable for widespread adoption as a practical agricultural tool. Attached image description:
[0007] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0008] Figure 1 is a front view of the present invention; Figure 2 is a left view of the present invention; Figure 3 is a top view of the present invention.
[0009] In the diagram: 1. First valve, 2. Second valve, 3. Third valve, 4. 90-degree connecting elbow, 5. 90-degree connecting elbow, 6. Three-way T-joint. Detailed implementation method:
[0010] This simple farmland irrigation device includes an exhaust pipe 9, an inlet pipe 7, a connecting pipe 10, and an outlet pipe 8, as well as a first valve 1, a second valve 2, and a third valve 3. The outlet pipe is connected to the connecting pipe 10 via a 90-degree connecting elbow 4, the inlet pipe 7 is connected to the connecting pipe 10 via a 90-degree connecting elbow 5, and the exhaust pipe 9 is connected to the connecting pipe 10 via a three-way T-joint 6.
[0011] In use, the device is placed on the embankment of the ditch, with the end of the inlet pipe 7 submerged in water. The second valve 2 and the third valve 3 are closed, and the first valve 1 is opened. Water is manually pumped to fill the vent pipe 9. Then, the first valve 1 is closed, and the second valve 2 is opened. The water in the vent pipe 9 falls naturally, displacing the air in the water intake pipe. Once the water in the vent pipe 9 has completely drained, the second valve 2 is closed again, and the first valve 1 is opened to fill it with water. By alternately opening and closing the first and second valves and filling and venting, all the air in the entire water intake pipe is eventually expelled and completely filled with water. After all the air has been expelled, ensuring the second valve is closed and the inlet pipe 7 is submerged, the third valve 3 is opened. This creates a siphon effect, allowing water in the ditch to continuously and automatically flow out through the water intake pipe from the outlet pipe 8.
