[0001] This utility model relates to the field of agricultural irrigation and drainage devices, and in particular to a buried paddy field irrigation and drainage device. Background Technology
[0002] With the rapid development of modern technology, the agricultural sector has also ushered in unprecedented technological innovation. In this development process, paddy field irrigation and drainage systems are a core component of agricultural development. These systems have improved agricultural production efficiency, promoted sustainable agricultural development, and driven agricultural modernization.
[0003] However, existing paddy field irrigation and drainage systems mainly rely on open field channels and pre-designed irrigation and drainage outlets. Although this traditional method has the advantage of being easy to operate, it still has the following problems: the crisscrossing irrigation and drainage channels inevitably occupy a large amount of arable land resources, directly reducing the effective planting area. These problems not only cause water loss due to evaporation, but also reduce the efficiency of farmland cultivation. Utility Model Content
[0004] This utility model proposes a buried paddy field irrigation and drainage device, which solves the problem of existing open channel water conveyance occupying a large amount of arable land resources and improves the practicality of the equipment.
[0005] The technical solution of this utility model is as follows:
[0006] A buried paddy field irrigation and drainage device includes irrigation and drainage piles, a water outlet, and a seepage pipe. The top of the irrigation and drainage pile is provided with a control structure for controlling the water flow switch, and the bottom of the irrigation and drainage pile is provided with an underground pipe connection port. The underground pipe connection port is connected to an underground water conveyance pipe buried underground. The underground water conveyance pipe is provided with a connection port, and the connection port is provided with a filter structure for preventing siltation.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0030] Example 1
[0031] like Figures 1-3 As shown in the figure, this embodiment proposes a buried paddy field irrigation and drainage device, which includes an irrigation and drainage pile 1, a water outlet 11, and a seepage pipe 2, forming a basic paddy field irrigation and drainage device. The top of the irrigation and drainage pile 1 is provided with a control structure 3 for controlling the water flow switch, so that field workers can operate the opening and closing of the water flow from the ground, which improves the convenience of operation and work efficiency.
[0032] The irrigation and drainage pile 1 is equipped with a pressurization device. In cases of long-distance water conveyance, high terrain, or insufficient water pressure, the pressurization device can be added to ensure that the water flow has sufficient pressure to reach the outlet 11. The bottom of the irrigation and drainage pile 1 is equipped with an underground pipe connection port 4, which connects the irrigation and drainage pile 1 with the underground water conveyance pipe 5. This is a key interface for external water sources to enter the irrigation and drainage pile during irrigation, or for field water to flow into the underground drainage network during drainage. The underground pipe connection port 4 connects to the underground water conveyance pipe 5, which has the advantages of saving cultivation space, protecting the pipe, and reducing water evaporation or pollution. The underground water conveyance pipe 5 is equipped with a connection port 51, and a filter structure 6 for preventing siltation is installed at the connection port 51. The paddy field water source often contains impurities such as mud, algae, and weeds. The filter structure 6 intercepts these impurities at the connection port 51, effectively preventing them from entering the underground water conveyance pipe 5, the irrigation and drainage pile 1, and the subsequent outlet 11 and seepage pipe 2, thus avoiding internal siltation and greatly reducing maintenance workload and failure rate.
[0033] In this embodiment, the filter structure 6 is located inside the underground water supply pipe 5. The filter structure 6 is detachably connected to the connection port 51. The detachable connection design facilitates the maintenance and replacement of the filter structure 6. Furthermore, placing the filter structure 6 outside the underground water supply pipe 5 further facilitates maintenance personnel to perform maintenance without entering and damaging the underground water supply pipe 5 or the soil layer. The filter structure 6 can be disassembled directly in the external water body.
[0034] like Figure 3 As shown, in this embodiment, the filter structure 6 includes a filter cylinder 61, a coarse filter screen 62, a semi-fine filter screen 66, a fine filter screen 63, a filter inlet 611, and a filter outlet 612. The filter outlet 612 is detachably connected to the connection port 51. The detachable design greatly simplifies the inspection or replacement of each filter screen, and each filter screen is snapped to the filter cylinder 61, which makes it convenient for maintenance personnel to replace the filter screen and reduces maintenance time and operational complexity.
[0035] The coarse filter screen 62 is located near the filter inlet 611. Placing the largest pore size screen 62 at the first position in the filter structure 6 prioritizes the interception of larger particulate impurities (such as sand, gravel, and debris) in the water flow. It also prevents large particles from directly impacting and quickly clogging the smaller pore size semi-fine filter screen 66 and fine filter screen 63, extending their service life. Simultaneously, it shares the main filtration load, allowing subsequent filters to focus on finer filtration tasks. The coarse filter screen 62 is made of stainless steel, which has the advantages of high strength and impact resistance. Under conditions of high water flow, the material of the coarse filter screen 62 can protect subsequent filters.
[0036] The semi-fine filter 66 is located between the coarse filter 62 and the fine filter 63. The pore size of the semi-fine filter 66 is between that of the coarse filter 62 and the fine filter 63, which significantly reduces the burden on the fine filter 63, captures medium-sized particles that have passed through the coarse filter 62, and allows the fine filter 63 to maintain its filtration performance for a longer period of time. At the same time, it disperses the filtration pressure between the coarse filter 62 and the fine filter 63, and extends the service life of the entire filter structure 6.
[0037] The fine filter screen 63 is located on the side near the filter outlet 612. It is responsible for removing the finest particles, ensuring the final filtration accuracy, and preventing blockage inside the underground water supply pipe 5 and irrigation and drainage pile 1.
[0038] By arranging three layers of filter screens with decreasing pore size, graded filtration of impurities of different particle sizes in the fluid is achieved. This design maximizes the capacity of each filter layer, significantly extends the lifespan of the fine filter screen 63, reduces the risk of subsequent clogging, and ensures the purity of the water flow.
[0039] Meanwhile, a sludge collection trough 64 for collecting large particles of impurities is also provided on the side of the filter cylinder 61 away from the ground or ground surface. The coarse filter screen 62, semi-fine filter screen 66, and fine filter screen 63 are all placed obliquely inside the filter cylinder 61, with the tilt angle aligned with the sludge collection trough 64. The impurities filtered out by the coarse filter screen 62, semi-fine filter screen 66, and fine filter screen 63 and attached to the surface of the filter screen will slide down the inclined surface of the filter screen under the action of gravity and water flow. Since the inclined surface is aligned with the sludge collection trough 64, these sliding impurities also fall into the sludge collection trough 64 due to gravity.
[0040] The sludge collection tank 64 is equipped with a drain pipe 65, which allows sludge to be discharged without disassembling the filter cartridge 61, reducing cleaning and maintenance costs. The drain pipe 65 is arranged on the same side as the filter inlet 611, optimizing the external pipeline connection and facilitating installation and operation. At the same time, the drain pipe 65 extends directly into the water, discharging the collected impurities directly into the water. The hydraulic gravity flow effect greatly improves the sludge discharge efficiency and further reduces manual cleaning costs.
[0041] In this embodiment, the portion of the irrigation and drainage pile 1 below the lower end of the outlet 11 is located underground, which not only connects to the underground water supply pipe 5, but also reduces material aging caused by the environment (sun exposure, frost). The portion above the lower end of the outlet 11 is exposed to the ground, which facilitates the inspection and maintenance of the inside of the irrigation and drainage pile 1.
[0042] In this embodiment, the water outlet 11 is irrigated through the cuff bag 12. The cuff bag 12 is provided with a connecting clamp 121 of the same diameter as the cuff bag 12 at one end near the water outlet 11. The connecting clamp 121 not only realizes the connection between the cuff bag 12 and the water outlet 11, but also provides structural strength for the cuff bag 12 to prevent deformation or detachment. The bolted connection between the connecting clamp 121 and the water outlet 11 reduces costs through a detachable connection. The bolted connection also allows for flexible replacement of various adapters to achieve different irrigation methods.
[0043] In this embodiment, the control handle 31 in the control structure 3 passes through the top of the irrigation pile 1, realizing vertical linear transmission and making full use of the axial space of the irrigation pile 1 to avoid lateral protrusions and prevent collisions with agricultural machinery. The top of the control handle 31 is exposed outside the irrigation pile 1, allowing field workers to operate the equipment from the ground. The bottom of the control handle 31 is fixedly connected to the center of the sealing plug 34. The sealing plug 34 and the base 35 with the same bottom shape as the sealing plug 34 abut or separate. When the control handle 31 is pressed down, due to its conformal matching design, the two abut together to form a uniform seal in the entire circumference, realizing the closure of the equipment. At this time, water cannot flow through. When the control handle 31 is pulled, the sealing plug 34 separates from the base 35, realizing the opening of the equipment. At this time, water flows through the base 35 to the outlet 11.
[0044] In this embodiment, a warning pole 16 is provided on the top of the irrigation and drainage pile 1, and a warning flag 161 is provided on the warning pole 16. The warning flag 161 is red and has reflective strips. The bright and warning color is more eye-catching in the farmland. The design of the reflective strips makes it also have a warning effect at night. This design can greatly reduce the collision accident rate and reduce maintenance costs.
[0045] The working process of this embodiment:
[0046] Before irrigation begins, connect the connecting clamp 121 on the cuff bag 12 to the outlet 11. After connection, the operator pulls the control handle 31 upwards, causing the sealing plug 34 to separate from the base 35, thus opening the water flow channel of the irrigation and drainage pile 1. At this time, the water flows through the underground water supply pipe 5, is filtered by the filter structure 6, enters the irrigation and drainage pile 1, and flows out from the cuff bag 12 into the paddy field.
[0047] Example 2
[0048] Based on the above embodiments, such as Figures 4-5 As shown, in this embodiment, a cement protective cover 15 is added to the top of the irrigation and drainage pile 1. The cement protective cover 15 covers the irrigation and drainage pile 1, and the water outlet 11 and the control structure 3 are set inside the irrigation and drainage pile 1. The part below the cement protective cover 15 is buried underground. This design can not only prevent the irrigation and drainage pile 1 from being damaged by agricultural machinery collisions, but also effectively reduce the impact of the environment or animals on it.
[0049] In this embodiment, the cement protective cover 15 is connected to the irrigation and drainage pile 1 by a snap-fit, which allows for quick opening of the cover to use the irrigation and drainage pile 1 or to inspect it. This solves the problem of cumbersome operation of the traditional bolt-fixed cover plate, which not only improves the protective strength but also improves the convenience of operation.
