Description

A kind of agricultural irrigation systems

Technical field

Agricultural irrigation technology is the utility model is related to, in particular to a kind of agricultural irrigation systems.

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：One kind how is provided to ooze Water is advantageous to the agricultural irrigation systems 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 systems, it is characterised in that be arranged in parallel including two and one end closing main water inlet tube, two There are the more leaky pipes being arranged side by side between the main water inlet tube, the both ends of the leaky pipe respectively with two main water inlets Pipe connects；The openend of any main water inlet tube is connected with intake pump, and the openend of another main water inlet tube connects Small pump is connected to, is all connected with being provided with overflow valve and accumulator on two main water inlet tubes；The flow of the intake pump and institute The flow sum for stating small pump is consistent with the seepage velocity sum of all leaky pipes.

Using said structure, due to carrying out water-filling to leaky pipe from both ends using intake pump and small pump simultaneously, can make The hydraulic pressure size at leaky pipe both ends is close, water percolating capacity than more uniform, can effectively prevent hydraulic pressure deficiency and cause effectively infiltration away from From effect shorter, that guarantee infiltration is irrigated.Due to the flow sum of intake pump and small pump and the seepage velocity of all leaky pipes Sum is consistent, it is possible to prevente effectively from the waste of water resource, is advantageous to economize on water.Overflow valve is set on two main water inlet tubes, can be with Avoid small pump or water inlet pump discharge undergo mutation, or infiltration hole plug and cause hydraulic pressure increase and explosion leaky pipe, improve system The stability of system work.Accumulator is set to ensure the pressure stability in soakaway trench, the irrigation effect that seeps water is more preferable.

Further, the leaky pipe includes outer tube and the inner tube being socketed in outer tube, and the internal diameter of the outer tube is more than institute The external diameter of inner tube is stated, is gathered on the tube wall of the outer tube and is provided with water seepage hole, it is equidistant along its length on the tube wall of said inner tube Water distributing pore is disposed with, the diameter of the water distributing pore is more than the diameter of the water seepage hole, and the water distributing pore in unit length The gross area is less than the gross area of the water seepage hole；It is airtight connection between the both ends of the outer tube and the outer surface of said inner tube.

So, after water is introduced into inner tube and then fills up the space between inner tube and outer tube, by the infiltration on outer tube Hole outflow is irrigated, because the gross area of the water distributing pore in unit length is less than the gross area of the water seepage hole, explanation Leakage of the current in inner tube unit length is smaller, thereby may be ensured that current can flow to more distant positions, is oozed so as to extend Effective creepage distance of fistulae.

In summary, the utility model has water percolating capacity than more uniform, and irrigation effect is preferable, the advantages that being advantageous to economize on water.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the structural representation of leaky pipe in Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

During specific implementation：As depicted in figs. 1 and 2, a kind of agricultural irrigation systems, including two be arranged in parallel and one end close Main water inlet tube 1, there are the more leaky pipes 2 being arranged side by side, the both ends of the leaky pipe 2 between two main water inlet tubes 1 Connected respectively with two main water inlet tubes 1；The openend of any main water inlet tube 1 is connected with intake pump 3, Ling Yigen The openend of the main water inlet tube 1 is connected with small pump 4, is all connected with being provided with overflow valve 5 and storage on two main water inlet tubes 1 Can device 6；The flow of the intake pump 3 and the flow sum of the small pump 4 and the seepage velocity sum of all leaky pipes 2 It is consistent.

When it is implemented, the intake pump is constant pressure variable displacement pump.

During implementation, the leaky pipe 2 includes outer tube 21 and the inner tube 22 being socketed in outer tube 21, the internal diameter of the outer tube 21 Gathered more than the external diameter of said inner tube 22, on the tube wall of the outer tube 21 and be provided with water seepage hole 23, on the tube wall of said inner tube 22 Equidistant placement has water distributing pore 24 along its length, and the diameter of the water distributing pore 24 is more than the diameter of the water seepage hole 23, and in list The gross area of the water distributing pore is less than the gross area of the water seepage hole on bit length；The both ends of the outer tube 21 and said inner tube 22 Outer surface between be airtight connection.

When it is implemented, it is wound with chemical fibre isolation cloth on the outer tube 21 so that water seepage hole is not easily blocked, and is advantageous to improve The service life of leaky pipe.

The lateral edges of the water distributing pore 24 outwardly have annular relief.So, the intensity of water distributing pore can be improved, is prevented Only too high hydraulic pressure tears water distributing pore, so as to influence effective creepage distance of leaky pipe.

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.
