Technical Field

[0001] The utility model relates to the technical field of farmland irrigation, in particular to a farmland underground pipe network water-saving infiltration irrigation system. Background Art

[0002] The farmland underground pipe network water-saving infiltration irrigation system is a highly efficient agricultural irrigation technology. It transports water to farmland through underground pipes, and uses osmosis to slowly infiltrate water into the soil, providing the moisture and nutrients needed for crop growth. This irrigation method has many advantages over traditional surface irrigation, such as saving water, reducing evaporation losses, and improving soil water retention capacity.

[0003] When the irrigation water is transported underground by the pipes buried underground, the irrigation water will penetrate and humidify the soil, so that while the water supply to crops is realized, the moist soil will adhere to the sides of the pipes. After the irrigation is completed, the moist soil attached to the sides of the pipes will flow to the inside of the outlet pipe. After drying for a period of time, it will block the inside of the outlet pipe, thereby affecting the water output of the outlet hole, further causing unevenness in the farmland irrigation area.

Example

[0028] See also Figure 1-Figure 4 , a farmland underground pipe network water-saving infiltration irrigation system shown in the figure includes an irrigation pipe 102 arranged under a cultivated land 101, a plurality of water outlet pipes 103 are arranged on the irrigation pipe 102, a water storage tower 105 is arranged on the cultivated land 101 through a bracket 104, one end of the irrigation pipe 102 is connected to the water storage tower 105, and also includes an anti-blocking mechanism arranged on each water outlet pipe 103 to prevent it from being blocked by soil and a telescopic component for telescoping the anti-blocking mechanism;

[0029] The anti-blocking mechanism includes a fixed pipe 201 arranged on the side of the water outlet pipe 103 away from the irrigation pipe 102, one end of the fixed pipe 201 is connected to the water outlet pipe 103 through a connecting assembly, the other end of the fixed pipe 201 is sealed, a blocking block 202 is slidably connected in the fixed pipe 201, and a conical block 203 is fixedly connected to the side of the blocking block 202 close to the irrigation pipe 102;

[0030] It should be noted here that: through the setting of the sealing mechanism, after the irrigation of the cultivated land 101 is completed, the sealing block 202 is pushed to seal the gap between the fixed pipe 201 and the outlet pipe 103 under the guidance and resetting action of the telescopic component, thereby blocking the flow of mud into the outlet pipe 103, avoiding the blockage of the outlet pipe 103 due to the drying of the soil, thereby ensuring the irrigation water output while ensuring the irrigation uniformity of the farmland irrigation area.

[0031] See also Figure 1-Figure 3 , the connecting assembly shown in the figure is a connecting rod 3, a plurality of connecting rods 3 are provided, each connecting rod 3 is arranged in a ring array, and both ends of each connecting rod 3 are respectively connected to the fixed pipe 201 and the water outlet pipe 103;

[0032] It should be noted that: by setting the connection assembly, when the fixed pipe 201 is connected to the water outlet pipe 103, a gap is created between the fixed pipe 201 and the water outlet pipe 103, thereby facilitating the overflow of the irrigation water.

[0033] See also Figure 3 , the length of each connecting rod 3 shown in the figure is less than the height of the blocking block 202;

[0034] It should be noted here that by limiting the length of the connecting rod 3 , it is ensured that the sealing block 202 completely seals the gap between the fixed pipe 201 and the water outlet pipe 103 .

[0035] See also Figure 3 The telescopic assembly shown in the figure includes two telescopic tubes 401 fixedly connected to the bottom wall of the fixed tube 201 and symmetrically arranged with each other, and the two telescopic tubes 401 are slidably connected with telescopic rods 402, one end of the two telescopic rods 402 is connected to the blocking block 202, and the other end of the two telescopic rods 402 is fixedly connected with a telescopic plate 403, and the other side of the two telescopic plates 403 is provided with a spring 404, and the other end of the two springs 404 is connected to the bottom wall of the telescopic tube 401;

[0036] It should be noted here that: by setting the telescopic component, a guiding and resetting function is provided for the movement of the blocking block 202 .

[0037] Working principle: When irrigating the cultivated land 101, the irrigation water in the water storage tower 105 is first transported to the outlet pipe 103 through the irrigation pipe 102 by a water pump. When the irrigation water is transported to the outlet pipe 103, the blocking block 202 is pushed to move close to the fixed pipe 201 under the driving effect of the water pressure and the guiding effect of the telescopic component. As the blocking block 202 continues to move, when the conical block 203 moves to the gap between the fixed pipe 201 and the outlet pipe 103, the irrigation water will overflow from the gap between the fixed pipe 201 and the outlet pipe 103, thereby realizing the irrigation of the cultivated land 101;

[0038] When the irrigation of the cultivated land 101 is completed and the irrigation water is no longer transported, the blocking block 202 will be reset under the elastic action of the telescopic component, thereby blocking the gap between the fixed pipe 201 and the outlet pipe 103, blocking the flow of mud into the outlet pipe 103, thereby avoiding the blockage of the outlet pipe 103 due to the drying of the soil, thereby ensuring the irrigation water output while ensuring the irrigation uniformity of the farmland irrigation area. Example

[0039] See also Figure 4 , this embodiment further explains Example 1, a rotating mechanism for rotating during the movement of the blocking block 202 is provided in the water outlet pipe 103 shown in the figure, the rotating mechanism includes a mounting rod 501 slidably connected in the water outlet pipe 103, one end of the mounting rod 501 is connected to the conical block 203, a spiral groove 502 is provided on the side wall of the mounting rod 501, a driving rod 503 is fixedly connected to the inner wall of the water outlet pipe 103, and the other end of the driving rod 503 slides in the spiral groove 502;

[0040] It should be noted here that: through the setting of the rotating mechanism, when the blocking block 202 moves upward, it will drive the installation rod 501 to move synchronously. During the movement of the installation rod 501, the blocking block 202 on the conical block 203 will be driven to rotate through the interaction force between the driving rod 503 and the spiral groove 502. Therefore, during the rotation of the blocking block 202, a shear force will be formed on the soil connected to the side wall of the blocking block 202, and the soil will be broken, thereby facilitating the overflow of irrigation water.

[0041] See also Figure 4 , the end of the driving rod 503 shown in the figure that slides in the spiral groove 502 has a rounded corner 504;

[0042] It should be noted here that the sliding friction of the driving rod 503 in the spiral groove 502 is reduced by setting the rounded corners 504 .

[0043] See also Figure 4The blocking block 202 shown in the figure is provided with a limiting assembly for limiting the two telescopic rods 402, and the limiting assembly includes an annular T-slot 601 provided on the side of the blocking block 202 close to the telescopic rod 402, and an annular T-plate 602 is rotatably connected in the annular T-slot 601, and one end of the telescopic rod 402 is connected to the annular T-plate 602;

[0044] It should be noted here that: by setting the limit assembly and utilizing the rotation effect of the annular T-slot 601 and the annular T-plate 602, the blocking block 202 will not interfere with the telescopic assembly during rotation, thereby ensuring the telescopic guiding effect of the telescopic assembly on the blocking block 202.
