Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural irrigation and drainage, and in particular relates to a novel integrated irrigation and drainage device. Background Art

[0002] Irrigation and drainage are crucial components of agricultural production and crucial constraints to its rapid development. my country's uneven distribution of water resources and low utilization rates have led to a decline in agricultural productivity and severely hampered the development of the agricultural economy. This has hindered the development of agriculture at a higher, faster, and better level. Existing farmland irrigation and drainage systems primarily rely on flood irrigation and canal irrigation, with drainage also primarily relying on ditches that drain water from high to low levels.

[0003] However, farmland ditches have poor drainage effectiveness and are significantly affected by topography. Heavy rains during the flood season can easily lead to flooding, resulting in significant property and economic losses. Furthermore, irrigation and drainage are primarily based on ditches, which are inefficient and result in significant evaporation and water resource losses during summer. Therefore, there is an urgent need for a new integrated irrigation and drainage device that can store water during droughts and drain water during floods, providing a sound irrigation system for agricultural production and development, fundamentally meeting the water resource needs of agricultural production and development, and effectively promoting agricultural production and development. Summary of the Invention

DETAILED DESCRIPTION

[0022] like Figures 1 to 3As shown, the present invention discloses a novel integrated irrigation and drainage device, comprising a vertically arranged irrigation and drainage pile 1. The irrigation and drainage pile 1 is a vertical tubular structure, sealed at the top by a top cover and at the bottom by a reinforced bottom cover. The entire structure adopts an ABR pipe, which is a composite of acrylic ester, polyvinyl chloride resin, a heat stabilizer, and other additives. The combination of acrylic ester and polyvinyl chloride produces an ultra-fine acrylic polymer (acrylieester, acrylic resin), which is then combined to improve the molecular chain combination to form an ABR blend material. The ABR blend material has low-temperature resistance, overcoming the low-temperature brittleness of traditional polyvinyl chloride materials and effectively solving the problem of low-temperature brittle fracture. Even in northern winters with temperatures as low as -30°C, the pipe still has high strength and impact resistance, and can withstand high internal pressure to ensure the realization of irrigation and drainage functions.

[0023] An irrigation pipe 2, a drainage and water collection pipe 3, and an underground pipe 4 are connected to the side of the irrigation and drainage pile 1 from top to bottom. A first switch valve 5 is provided in the irrigation pipe 2. The first switch valve 5 adopts a DN125 butterfly valve. The DN125 butterfly valve is a regulating valve with a simple structure. Its main function is to cut off the flow of water in the pipeline or adjust the water flow in the pipeline. A one-way valve 6 is provided in the drainage and water collection pipe 3, and the underground pipe 4 is connected to a second switch valve and a water supply boosting system. The water supply boosting system can adopt a conventional water supply boosting pump or a water reservoir with a certain potential energy. During irrigation, the water supply boosting system applies pressure to the irrigation and drainage pile 1 while supplying water, causing the water level in the irrigation and drainage pile 1 to rise and triggering the one-way valve 6 to close, and irrigation is carried out through the irrigation pipe 2. During drainage, the rainy season water flows into the irrigation and drainage pile 1 through the drainage and water collection pipe 3 and then is discharged through the underground pipe 4. During water storage, the second switch valve is closed, and the water collected through the drainage and water collection pipe 3 is stored in the irrigation and drainage pile 1, and is output for use when needed, thereby avoiding waste of water resources. The device of the present invention combines drainage, irrigation and water storage, thereby improving the ability to optimize water resource allocation and the defense capability against floods and droughts.

[0024] The water booster system can be a small booster installed at the end of the underground pipe network to overcome the flow resistance and gravity during irrigation. Alternatively, it can be a reservoir that cannot be actively controlled but can be adjusted by a second on-off valve to ensure optimal water supply.

[0025] In this embodiment, the second on-off valve comprises a first water plate 7, an upward limiter 8, a second water plate 9, a connecting rod 10, and a slider 11. The first water plate 7 is positioned above the second water plate 9 and fixed to the inner side of the irrigation and drainage pile 1. The slider 11 is slidably disposed within the underground pipe 4 and connected to the second water plate 9 via the connecting rod 10. The second water plate 9 slides against the inner wall of the irrigation and drainage pile 1, and its upward position is limited by the upward limiter 8. The first and second water plates 7, 9 are respectively provided with first and second water holes 12, 13, which are axially staggered. In the irrigation mode, the upward limiter 8 opens, restricting the second water plate 9 to the lower side of the first water plate 7. Water from the lower portion passes through the second and first water holes 13, 12, and enters the irrigation pipe 2 for irrigation. To avoid over-irrigation, the upward limiter 8 is closed, and the second water plate 9 rises under the action of buoyancy and abuts the first water plate 7. The first water hole 12 and the second water hole 13 are respectively closed by the second water plate 9 and the first water plate 7, automatically blocking the water from entering the irrigation pipe 2, thereby preventing the possibility of over-irrigation. The present invention can adjust and close the irrigation and drainage pile 1 as a whole without the need for excessive valve structures, and also avoids the cumbersome adjustment problem caused by opening and closing multiple irrigation pipes 2 one by one.

[0026] In this embodiment, a downward limiting device 14 for limiting the downward position of the second water-passing plate 9 is also fixed to the inner side of the irrigation and drainage pile 1, a stepped hole 15 is provided in the underground pipe 4, and an axially non-connected water-passing groove 16 is provided on the surface of the slider 11; when the water-passing groove 16 cooperates with the large hole of the stepped hole 15, water can pass through. Similarly, when the water-passing groove 16 completely cooperates with the inner wall of the small hole of the stepped hole 15, it can be closed. The connecting rod 10 includes an outer rod 17, an inner rod 18 and a spring 19. One end of the inner rod 18 is hinged to the slider 11, and the other end is slidably arranged on the inner side of the outer rod 17. A spring 19 is also connected between the outer rod 17 and the inner rod 18. When there is a lack of water, the gravity of the second water-passing plate 9 acts on the slider 11 through the connecting rod 10, so that the slider 11 closes the underground pipe 4, and the drainage and water collection pipe 3 discharges the water into the irrigation and drainage pile 1 for storage. When the water level rises, the buoyancy drives the second water-passing plate 9 to rise, driving the slider 11 to move so that the underground pipe 4 is opened, thereby realizing periodic water storage and discharge.

[0027] In this embodiment, the upward limiter 8 includes a stopper plate 20 and a telescopic device 21. The telescopic device 21 is fixedly connected to the irrigation and drainage pile 1, and the stopper plate 20 is connected to the output end of the telescopic device 21. The stopper plate 20 can move radially along the irrigation and drainage pile 1 to stop the second water-passing plate 9. The downward limiter 14 includes a stopper ring fixed to the inside of the irrigation and drainage pile 1, located below the second water-passing plate 9. The telescopic device 21 can be a conventional hydraulic cylinder or directly controlled by manual extension and retraction, depending on the needs.

[0028] In this embodiment, the one-way valve 6 comprises an internal pipe 22, a bracket 23, and a float 24. The internal pipe 22 is connected to the drainage and water collection pipe 3 and is vertically fixed inside the irrigation and drainage pile 1. The lower end of the internal pipe 22 is connected to the bracket 23. A float 24 is movably mounted within the bracket 23, which seals the internal pipe 22 when it rises. A circular floating ball device is designed within the drainage and water collection pipe 3. During drainage, the float rests at the bottom, allowing accumulated water to flow into the device due to gravity. During irrigation, the rising water level in the pipe creates buoyancy on the float 24, blocking the drainage and water collection outlet and preventing overflow and backflow of irrigation water.

[0029] In this embodiment, a filter screen 25 is provided in the drainage and water collection pipe 3 to prevent foreign matter from entering the device.

[0030] In this embodiment, the irrigation pipe 2 includes a pipe body, and a rubber pad 26, a saddle joint 27, a flange 28, a flange section 29, a first switch valve 5, and a water diversion belt interface 30 are arranged in sequence along the axial direction of the pipe body. The function of the rubber pad 26 and the rubber ring is to seal and prevent water leakage, and the tightness of the flange can also be appropriately adjusted, which is beneficial to irrigation operations. The saddle joint 27 adopts a PVC saddle joint, which is used to connect the pipe body to the irrigation and drainage pile 1; the flange 28 and the flange section 29 are used to connect one side of the water diversion belt interface 30, and the other side of the water diversion belt interface 30 is used to directly connect the irrigation water hose.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
