Description
Technical field
Agricultural irrigation technology is the utility model is related to, in particular to a kind of agricultural irrigation leaky pipe.
Background technology
According to statistics, China's agricultural water accounts for more than the 80% of national total water consumption, using water wisely, reduces the loss of water, hair
Open up high-efficiency water-saving agricultural has turned into the fundamental state policy in China, and the form of agricultural irrigation is a lot, there is furrow irrigation, sprinkling irrigation, drip irrigation and infiltrating irrigation
Deng, wherein with infiltrating irrigation science the most and advanced, not only economize on water, section fertilizer, and save manpower and reduce labor intensity, to environment and soil
Earth can also play a protective role.Infiltrating irrigation is to use the soakaway trench with some water seepage holes to be layed in the ground such as farmland, forest land, nursery
On, then it is connected water source, pass water through the hydraulic pressure of raising and oozed out through water seepage hole, to soak soil, supply is planted plants in soil
Moisture needed for thing.But existing soakaway trench comes with some shortcomings in actual use, 1. effective creepage distances are short, because existing
Soakaway trench linking water source after, that is, the state of full tube wall sweat is presented, because the infiltration length of tube is long, have infiltration deficiency or
The problem of anhydrous, cause effective creepage distance shorter, and the purpose that Accurate Points ooze can not be reached.2. it is not easy control infiltration really
Amount, because existing soakaway trench is that whole pipeline permeates entirely, often have excessive close to water source end water percolating capacity, long-range water percolating capacity is not
Foot, can not control the irrigation volume of moisture needed for crops or liquid fertilizer really, cause unnecessary waste, be unfavorable for economizing on water.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How to provide one kind has
It is longer to imitate creepage distance, water percolating capacity is advantageous to the agricultural irrigation leaky pipe of water saving than more uniform.
In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：
A kind of agricultural irrigation leaky pipe, including outer tube and the inner tube that is socketed in outer tube, it is characterised in that the outer tube
Internal diameter be more than the external diameter of said inner tube, gather on the tube wall of the outer tube and be provided with water seepage hole, edge on the tube wall of said inner tube
Length direction has been sequentially arranged water distributing pore, 2~3 times of the diameter of a diameter of water seepage hole of the water distributing pore；Duct length
Spacing on direction between the two neighboring water distributing pore is gradually reduced along the water (flow) direction in said inner tube, and minimum spacing is
2~4 times of the spacing of the two neighboring water seepage hole on length direction, on the pipeline section of any equal length, the water distributing pore
The gross area be less than the water seepage hole the gross area；It is closed company between the both ends of the outer tube and the outer surface of said inner tube
Connect；Chemical fibre isolation cloth is wound with the outer tube.
Using said structure, because the spacing between adjacent water distributing pore is gradually reduced along inner tube water (flow) direction so that inner tube
Close to water inlet end water distribution hole density it is smaller, current loss it is also smaller, and away from water inlet end position, due to the pressure of current
It is smaller, and water distribution hole density is relatively large, so as to ensure the end for thering is enough water to enter leaky pipe.Water enter inner tube and
After between outer tube, then penetrated into from the water seepage hole of outer tube in soil.Using said structure, effective infiltration of leaky pipe can be caused
Distance is longer, and water percolating capacity is advantageous to economize on water than more uniform.Further, since chemical fibre isolation cloth is wound with outer tube so that water seepage hole
It is not easily blocked, is advantageous to improve the service life of leaky pipe.
Further, the lateral edges of the water distributing pore outwardly have annular relief.
So, the intensity of water distributing pore can be improved, prevents too high hydraulic pressure from tearing water distributing pore, so as to influence leaky pipe
Effective creepage distance.
In summary, the utility model has that effective creepage distance is longer, and it is excellent to be advantageous to water saving etc. than more uniform for water percolating capacity
Point.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
During specific implementation：As shown in figure 1, a kind of agricultural irrigation leaky pipe, including outer tube 1 and it is socketed in outer tube 1
Inner tube 2, the internal diameter of the outer tube 1 are more than the external diameter of said inner tube 2, are gathered on the tube wall of the outer tube 1 and be provided with water seepage hole 3,
Water distributing pore 4 has been sequentially arranged on the tube wall of said inner tube 2 along its length, a diameter of water seepage hole 3 of the water distributing pore 4
2~3 times of diameter；Spacing in pipe lengths between the two neighboring water distributing pore 4 is along the current side in said inner tube 2
To being gradually reduced, and minimum spacing is 2~4 times of the spacing of the two neighboring water seepage hole on length direction, any identical
On the pipeline section of length, the gross area of the water distributing pore 4 is less than the gross area of the water seepage hole 3；The both ends of the outer tube 1 with it is described
It is airtight connection between the outer surface of inner tube 2；Chemical fibre isolation cloth is wound with the outer tube 1.
Using said structure, because the spacing between adjacent water distributing pore is gradually reduced along inner tube water (flow) direction so that inner tube
Close to water inlet end water distribution hole density it is smaller, current loss it is also smaller, and away from water inlet end position, due to the pressure of current
It is smaller, and water distribution hole density is relatively large, so as to ensure the end for thering is enough water to enter leaky pipe.Water enter inner tube and
After between outer tube, then penetrated into from the water seepage hole of outer tube in soil.Using said structure, effective infiltration of leaky pipe can be caused
Distance is longer, and water percolating capacity is advantageous to economize on water than more uniform.Further, since chemical fibre isolation cloth is wound with outer tube so that water seepage hole
It is not easily blocked, is advantageous to improve the service life of leaky pipe.
Because on the pipeline section of any equal length, the gross area of the water distributing pore 4 is less than total face of the water seepage hole 3
Product；Illustrate that leakage of the current in inner tube unit length is smaller, thereby may be ensured that current can flow to more distant positions, so as to
Extend effective creepage distance of leaky pipe.
During implementation, the lateral edges of the water distributing pore 4 outwardly have annular relief.
So, the intensity of water distributing pore can be improved, prevents too high hydraulic pressure from tearing water distributing pore, so as to influence leaky pipe
Effective creepage distance.
When it is implemented, a diameter of infiltration 2~3 times of bore dia of the water distributing pore, the water distributing pore is along inner tube
Circumferential direction is evenly equipped with 3, and circumferential direction of the water seepage hole along outer tube is evenly equipped with 6, and the adjacent cloth on length direction
The minimum spacing in water hole is 3 times of the spacing of the water seepage hole.Spacing on length direction between the two neighboring water distributing pore
Arranged in the longitudinal direction in Geometric Sequence, it is 1 to wait than ratio:1.1.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not using the utility model as limitation
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
