Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape technology, and in particular to an anti-clogging structure for drip irrigation tape. Background Technology

[0002] Existing drip irrigation tapes typically involve drilling holes at regular intervals (e.g., 30cm, 50cm, 75cm, 100cm) into smooth PE pipes (usually with thick walls, such as 0.6mm-2.0mm). Individual drippers are then installed in these holes. These drippers can be pressure-compensated or non-pressure-compensated. Traditional pressure-compensated or non-pressure-compensated drippers are prone to clogging due to narrow flow channels caused by silt, algae, or scale, leading to uneven irrigation or even system failure. Furthermore, continuous dripping can cause salt crystals to form at the drip holes (especially in areas with hard water), accelerating clogging.

[0003] Therefore, it is necessary to provide a new anti-clogging structure for drip irrigation tape to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an anti-clogging structure for drip irrigation tape.

[0005] The drip irrigation tape anti-clogging structure provided by this utility model includes a water storage cylinder, and an overflow pipe and a connecting pipe that are connected to the water storage cylinder are respectively fixedly installed at the upper and lower ends of the water storage cylinder.

[0006] The inner wall of the water storage cylinder near the top is provided with several U-shaped flow channels distributed in annularly, and a limit ring is fixedly installed on the water storage cylinder between the two openings of the U-shaped flow channels.

[0007] The water storage tank is equipped with a pressurization component, which includes a piston. The piston is slidably installed inside the water storage tank, and a sliding column is fixedly installed on the upper surface of the piston. The sliding column is inserted into the overflow pipe and slidably connected to the overflow pipe. A spring A is sleeved on the sliding column.

[0008] Preferably, one end of the spring A is fixedly connected to the upper surface of the piston, and the other end of the spring A is fixedly connected to the inner top wall of the water storage tank.

[0009] Preferably, a horizontally arranged side pipe is fixedly installed on the overflow pipe, and a drip tube perpendicular to the side pipe is fixedly installed on the side pipe.

[0010] Preferably, the drip tube is equipped with an intermittent dripping device, and the intermittent dripping device includes a mounting bracket. The mounting bracket is fixedly installed in the side tube, and a sliding rod is inserted in the mounting bracket. The head of the sliding rod is fixedly installed with a steel ball for blocking the overflow port of the side tube, and a spring B is sleeved on the sliding rod.

[0011] Preferably, one end of the spring B is fixedly connected to the spherical surface of the steel ball, and the other end of the spring B is fixedly connected to the mounting bracket.

[0012] Preferably, the root of the connecting pipe is provided with a threaded portion, and multiple annularly distributed water inlet holes are provided on the pipe body of the connecting pipe below the threaded portion.

[0013] Compared with related technologies, the anti-clogging structure of drip irrigation tape provided by this utility model has the following beneficial effects:

[0014] 1. The curved design of the U-shaped flow channel in this utility model forces the water flow to change direction and uses centrifugal force to separate impurities (mud and sand are deposited at the bottom of the U-shape). The limiting ring restricts the piston's upward movement height, ensuring that the U-shaped flow channel only opens when the water pressure in the storage tank reaches the standard, preventing small particles from entering the overflow pipe. The pre-compression force of spring A sets the critical pressure, so that when the water pressure is insufficient, the piston closes the inlet of the U-shaped flow channel to prevent impurities from entering. When the water pressure increases, the piston moves upward, and the water flows through the U-shaped flow channel for filtration and enters the overflow pipe.

[0015] 2. In this utility model, the steel ball periodically opens and closes the overflow port of the side pipe to form a pulsed dripping water. This causes the drip hole to dry briefly each time it is closed, blocking the accumulation of salt caused by water evaporation and significantly reducing the risk of crystallization. Meanwhile, the intermittent dripping device drives the drip tube to drip intermittently, allowing water to fully infiltrate, reducing surface evaporation and improving water resource utilization.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a drip irrigation tape anti-clogging structure, which includes a water storage tank 1, a pressurization component 4, and an intermittent dripping component 5.

[0024] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 3 The upper and lower ends of the water storage tank 1 are respectively fixedly installed with an overflow pipe 3 and a connecting pipe 2 that are connected to the water storage tank 1. The root of the connecting pipe 2 is provided with a threaded part 21, and multiple annularly distributed water inlet holes 2a are opened on the pipe body of the connecting pipe 2 below the threaded part 21. Several annularly distributed U-shaped flow channels 1a are opened on the inner wall of the water storage tank 1 near the top, and a limit ring 11 is fixedly installed on the water storage tank 1 between the two openings of the U-shaped flow channel 1a.

[0025] The water storage tank 1 is equipped with a pressurization component 4, which includes a piston 41. The piston 41 is slidably installed inside the water storage tank 1, and a sliding column 42 is fixedly installed on the upper surface of the piston 41. The sliding column 42 is inserted into the overflow pipe 3 and slidably connected to the overflow pipe 3. A spring A43 is sleeved on the sliding column 42. One end of the spring A43 is fixedly connected to the upper surface of the piston 41, and the other end of the spring A43 is fixedly connected to the inner top wall of the water storage tank 1.

[0026] It should be noted that: the tube body of the connecting pipe 2 below the threaded part 21 is inserted into the threaded interface of the drip irrigation tape, and then the connecting pipe 2 is rotated to drive the threaded part 21 to be threadedly fixedly connected to the threaded interface of the drip irrigation tape. The water transported by the drip irrigation tape enters the connecting pipe 2 through the water inlet 2a and flows into the water storage tank 1 through the connecting pipe 2.

[0027] When the water in the water tank 1 rises, the water pressure increases, which pushes the piston 41 to slide up and compresses the spring A43 until the piston 41 abuts against the limit ring 11. At this time, water enters through the lower orifice of the U-shaped flow channel 1a and overflows through the upper orifice of the U-shaped flow channel 1a, so that the water flows into the overflow pipe 3.

[0028] If the water pressure in the water tank 1 is less than that of the spring A43, the piston 41 slides down to below the lower orifice of the U-shaped flow channel 1a, and thus the overflow pipe 3 stops receiving water.

[0029] The curved design of the U-shaped flow channel 1a forces the water flow to change direction, using centrifugal force to separate impurities (silt and sand are deposited at the bottom of the U-shape). The limiting ring 11 restricts the upward movement of the piston 41, ensuring that the U-shaped flow channel 1a only opens when the water pressure in the water storage tank 1 meets the standard, preventing small particles from entering the overflow pipe. The pre-compression force of the spring A43 sets the critical pressure, so that when the water pressure is insufficient, the piston 41 closes the inlet of the U-shaped flow channel 1a to prevent impurities from entering. When the water pressure increases, the piston 41 moves upward, and the water flows through the U-shaped flow channel 1a for filtration and enters the overflow pipe 3.

[0030] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 4 A horizontally arranged side pipe 31 is fixedly installed on the overflow pipe 3, and a drip pipe 32 perpendicular to the side pipe 31 is fixedly installed on the side pipe 31. An intermittent dripping component 5 is installed inside the drip pipe 32, and the intermittent dripping component 5 includes a mounting bracket 51. The mounting bracket 51 is fixedly installed inside the side pipe 31, and a sliding rod 52 is inserted into the mounting bracket 51. A steel ball 53 for blocking the overflow port of the side pipe 31 is fixedly installed on the head of the sliding rod 52, and a spring B 54 is sleeved on the sliding rod 52. One end of the spring B 54 is fixedly connected to the spherical surface of the steel ball 53, and the other end of the spring B is fixedly connected to the mounting bracket 51.

[0031] It should be noted that: when the amount of water in the overflow pipe 3 increases, it overflows towards the side pipe 31. When the water pressure in the overflow pipe 3 increases, the steel ball 53 slides along the mounting bracket 51 via the sliding rod 52. At this time, the spring B54 is compressed. When the steel ball 53 slides past the interface between the drip tube 32 and the side pipe 31, the water can drip from the drip tube 32. When the water pressure is less than the spring B54, the steel ball 53 resets, so that the interface between the drip tube 32 and the side pipe 31 no longer drips.

[0032] Among them, the steel ball 53 periodically opens and closes the overflow port of the side pipe 31 to form a pulsed drip, so that the drip hole dries briefly each time it is closed, blocking the accumulation of salt caused by water evaporation and significantly reducing the risk of crystallization. Meanwhile, the intermittent dripping component 5 drives the drip pipe 32 to drip intermittently, so that water can fully infiltrate downward, reduce surface evaporation, and improve water resource utilization.

[0033] In this embodiment, the spring force coefficient of spring B54 is less than that of spring A43, and springs A43 and B54 are made of ceramic-coated springs or corrosion-resistant alloy materials (such as Hastelloy) to improve their service life.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
