Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a filter-type underground drainage device for farmland. Background Technology

[0002] Underground drainage systems for farmland are concealed drainage systems installed underground to remove excess water from the soil. These systems consist of multiple corrugated pipes with evenly spaced openings in the pipe walls. A nylon sleeve covers the outside of the pipes, preventing impurities from entering while absorbing excess water from the soil and transporting it to the main pipe or collection well for discharge outside the farmland. However, their use has the following drawbacks:

[0003] 1. Although the nylon sleeve wrapped around the pipe can block large soil particles and crop residues, fine sand and clay particles will gradually adhere to the sleeve surface or enter the pipe wall openings as water seeps in during long-term use, causing the drainage capacity of the underground pipe to decrease or even become completely ineffective.

[0004] 2. When underground pipes are buried, it is difficult to determine the area of ​​blockage when blockage occurs. Furthermore, the maintenance and cleaning of the pipes require excavation to remove the soil and clean or replace them, which not only damages the topsoil of the farmland but also incurs high costs for labor, equipment, and recultivation. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is insufficient filtration effect, difficulty in maintaining and cleaning clogged areas, and high maintenance costs.

[0007] II. Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a filter-type underground drainage device for farmland, comprising multiple pipe sections connected together and buried in the soil;

[0009] The tube body includes a telescopic corrugated pipe and two horizontal pipes connected to the two ends of the telescopic corrugated pipe. It can be moved in sections. The side wall of the two horizontal pipes is evenly provided with multiple openings along the circumferential and length directions. A nylon sleeve, a sponge tube and a mesh tube are sequentially sleeved on the outside of the openings.

[0010] The horizontal pipe is connected to a vertical pipe at one end. The upper end of the vertical pipe extends out of the soil and is fitted with a sealing cap. A detachable funnel-shaped water inlet pipe is inserted into the vertical pipe to detect blockages in the pipe.

[0011] As an improvement, one end of the horizontal tube is connected to a plug ring that fits into the second horizontal tube. The plug ring is composed of a frustum ring and a cylindrical ring that is in contact with the inner wall of the second horizontal tube. The outer wall of the cylindrical ring is provided with a rubber ring, and the inner wall of the second horizontal tube is provided with an annular groove that fits with the rubber ring.

[0012] As an improvement, the inner wall of the insert ring is inserted into one end of the horizontal tube two in an arc-shaped curved surface structure.

[0013] As an improvement, a limiting ring is fixedly provided on the outer wall of the horizontal tube two near the telescopic corrugated tube, the nylon sleeve is attached to the limiting ring, and the side wall of the horizontal tube two is fitted with a limiting ring two that is attached to the other end of the nylon sleeve. The inner wall of the limiting ring two is provided with a rubber ring two, and the outer wall of the horizontal tube two is provided with an annular groove two that cooperates with the rubber ring two.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1-4 As shown, a filter-type underground drainage system for farmland includes multiple pipe sections 1, which are connected and buried in the soil. Each pipe section 1 includes a telescopic corrugated pipe and two horizontal pipes connected to the two ends of the telescopic corrugated pipe. The sidewalls of the two horizontal pipes are evenly provided with multiple openings 2 along the circumferential and length directions. A nylon sleeve 3, a sponge cylinder 4, and a mesh cylinder 5 are sequentially sleeved on the outside of the openings 2, forming a multi-layer filtration structure. The mesh cylinder 5 preferentially blocks large particles and crop residues in the soil, preventing them from directly contacting the inner filtration structure and reducing the clogging pressure on the outer layer. The sponge cylinder 4 utilizes the porous adsorption characteristics of sponges to further filter fine sand and clay particles in the water, while also buffering the impact of water flow on the nylon sleeve 3, extending the service life of the nylon sleeve 3. The nylon sleeve 3, as the last filtration barrier, accurately blocks tiny impurities, achieving graded blocking and multiple protection.

[0027] The upper end of the horizontal pipe is connected to a vertical pipe 6. The upper end of the vertical pipe 6 extends out of the soil and is fitted with a sealing cap 7. A detachable funnel-shaped water inlet pipe 8 is inserted into the vertical pipe 6 to detect blockages in the pipe body 1. If a blockage is suspected, the sealing cap 7 on the vertical pipe 6 is opened, the funnel-shaped water inlet pipe 8 is inserted, and clean water is injected into the pipe. If the clean water flows quickly into the pipe body 1 and continues to flow downward, it indicates that the pipe body 1 is unobstructed. If the clean water accumulates in the vertical pipe 6 and cannot flow downward, or if the flow speed is significantly reduced, it can be determined that the pipe body 1 corresponding to the vertical pipe 6 is blocked. Maintenance can be carried out on the pipe body 1 corresponding to the blockage, improving the efficiency of blockage detection and avoiding damage to the farmland topsoil by blind excavation, thus reducing maintenance costs.

[0028] The horizontal tube is connected to a ring 9 at one end, which is inserted into the horizontal tube 2. The ring 9 is composed of a frustum ring and a cylindrical ring that is in contact with the inner wall of the horizontal tube 2. The outer wall of the cylindrical ring is provided with a rubber ring 10, and the inner wall of the horizontal tube 2 is provided with an annular groove 11 that cooperates with the rubber ring 10. After the ring 9 is inserted into the horizontal tube 2, the rubber ring 10 and the annular groove 11 cooperate to achieve a tight connection, which makes it easy to disassemble the tubes 1. The horizontal tube 1 and the horizontal tube 2 connected by the telescopic corrugated pipe can be moved in sections, making it easier to remove the horizontal tube 2 in the filter area for replacement or cleaning, thus reducing maintenance costs.

[0029] Furthermore, a support ring 16 is fixedly provided on the inner wall of the horizontal pipe. Multiple horizontal rods 17 extending into the telescopic corrugated pipe are evenly provided on the inner wall of the support ring 16 along the circumferential direction, which serve to support the telescopic corrugated pipe and prevent it from being squeezed and closed due to soil pressure.

[0030] Furthermore, the inner wall of the insert ring 9 is inserted into the horizontal pipe 2 at one end with an arc-shaped curved surface structure, and the cross-section of the support ring 16 is trapezoidal, so that the water can flow more smoothly through the support ring 16 and the insert ring 9 when it passes through the pipe body 1, and avoid excessive water accumulation in the pipe body 1.

[0031] Furthermore, a limiting ring 12 is fixedly provided on the outer wall of the horizontal tube second near the telescopic corrugated tube. The nylon sleeve 3 is attached to the limiting ring 12, and a limiting ring 13 is sleeved on the side wall of the horizontal tube second and attached to the other end of the nylon sleeve 3. The inner wall of the limiting ring 13 is provided with a rubber ring 14, and the outer wall of the horizontal tube second is provided with an annular groove 15 that cooperates with the rubber ring 14. After removing the limiting ring 13, the filter structure can be taken out, making the filter structure easy to disassemble and replace. Damaged filter structures can be replaced individually without replacing the entire tube body, thus reducing consumable costs.
