Description

Technical Field

[0001] The utility model relates to the field of drip irrigation pipes, in particular to an underground pressure-compensating anti-blocking drip irrigation pipe. Background Art

[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through holes or drippers on a capillary tube with a diameter of about 10 mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-scarce areas.

[0003] During use, the drippers installed on the existing drip irrigation pipes are easily blocked by the soil at the water outlet after being buried underground, which is inconvenient for inspection and maintenance. In addition, the water flow rate of the drippers is not easy to adjust. When the water pressure increases, the drippers cannot adjust to adapt to the water pressure, which can easily lead to excessive water output. Utility Model Content

[0024] Working principle: When the water pressure inside the drip irrigation pipe 2 is relatively high, water can flow into the water inlet tube 31 from the water inlet 32 ​​and impact the rubber sheet 34. The deformed rubber sheet 34 will block the drip irrigation port 36 on the opposite side, thereby significantly reducing the outlet pressure at the drip irrigation port 36.

[0025] When the water filling pressure inside the drip irrigation pipe 2 is relatively low, the impact force acting on the surface of the rubber sheet 34 becomes smaller, the rubber sheet 34 is less deformed, the degree of compression of the drip irrigation port 36 on the opposite side is reduced, and the head pressure loss caused at the drip irrigation port 36 is reduced, thereby achieving a constant pressure at the drip irrigation port 36 within a certain pressure change range inside the drip irrigation pipe 2, that is, the water output from the drip irrigation port 36 remains uniform and stable, and water saving is achieved through pressure compensation.

[0026] As a preferred embodiment, the bottom of the water inlet cylinder 31 covers the surface of the rubber sheet 34 , and the rubber sheet 34 is rectangular. Meanwhile, the rubber sheet 34 is horizontally arranged inside the pressure compensation drip irrigation assembly 3 .

[0027] like Figure 2-7 As shown: the rubber sheet 34 is horizontally arranged inside the pressure compensation drip irrigation assembly 3;

[0028] When the water pressure inside the drip irrigation pipe 2 is too high, the rubber sheet 34 is highly deformed, and the extrusion, covering and sealing of the drip irrigation port 36 is relatively tight;

[0029] When the water pressure inside the drip irrigation pipe 2 decreases, the rubber sheet 34 is less deformed, and the squeeze, cover and seal of the drip irrigation port 36 are relatively loose;

[0030] As a preferred embodiment, the air intake area 33 and the drainage area 37 are connected via a connecting area 38 , and the heights of the air intake area 33 and the drainage area 37 are consistent.

[0031] The water inlet 32 ​​and the drip irrigation port 36 are arranged opposite to each other, and the diameters of the water inlet 32 ​​and the drip irrigation port 36 are consistent, and the diameters of the water inlet 32 ​​and the drip irrigation port 36 are both 0.8 mm.

[0032] The diameter of the drip irrigation port 36 is 0.8 mm, and water drips out from the drip irrigation port 36 and penetrates into the soil to moisten and irrigate the soil.

[0033] As a preferred embodiment, a plurality of groups of positively deformed isolation holes are evenly formed on the surface of the stainless steel mesh 39, and the cross section of the stainless steel mesh 39 is a "U"-shaped structure.

[0035] like Figure 1-7 As shown, the stainless steel mesh 39 covers the outer side of the base 35 , and can protect the drip irrigation port 36 on the base 35 to prevent the drip irrigation port 36 from being blocked by moist soil particles.

[0036] The water inside the drip irrigation pipe 2 enters the water inlet cylinder 31 from the water inlet 32 ​​and squeezes and deforms the rubber sheet 34 , and the water inside the water inlet cylinder 31 drips out from the air intake area 33 , the communication area 38 and the drainage area 37 and finally from the drip irrigation port 36 .
