Description

Technical Field

[0001] The present invention relates to the field of agriculture, and particularly to an efficient and energy-saving drip irrigation system. Background Art

[0002] Traditional agricultural irrigation methods mainly include flood irrigation, sprinkler irrigation, and drip irrigation, etc. Among them, drip irrigation, as an efficient and energy-saving irrigation method, has the advantages of water conservation, energy conservation, and high efficiency, and has gradually been widely used in modern agriculture. The drip irrigation system delivers water directly to the roots of plants, reducing water waste. At the same time, it can accurately control the irrigation amount according to the needs of plants, improving the utilization efficiency of water resources. However, there are still some problems in the application of existing drip irrigation systems, including the clogging problem of drip heads and uneven pressure distribution.

[0003] In response to these problems, some improvement schemes have been proposed in the prior art, but there are still certain limitations. For example, the patent with the publication number CN106171848B discloses an inlaid pressure-compensating drip head, drip irrigation tape, and drip irrigation method. By setting components such as an external maze turbulent flow channel and a punching groove on the lower surface of the drip head body, it is used to achieve the purpose of uniform drip head flow under different pressures. However, it still has the following deficiencies: 1. Uneven pressure: Difficult water discharge when water pressure is insufficient: In the comparative patent, when the water pressure is insufficient, due to the complex design of the internal and external maze turbulent flow channels, the water flow needs to go through multiple turns and blockages, resulting in an increase in water flow resistance and making it difficult to smoothly pass through the flow channel and discharge from the drip head, thereby affecting the irrigation effect. 2. Uneven flow rate: In the comparative patent, the flow rate of the drip head changes greatly with the water pressure. The water discharge is too large at high water pressure and too small at low water pressure, making it difficult to ensure a uniform irrigation effect. Especially in the case of complex terrain or long transmission distance, this problem is more likely to occur. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an efficient and energy-saving drip irrigation system, which solves the problems existing in the prior art. Through the combined action of the elastic diaphragm and the pressure compensation head inside the drip head, it can automatically adjust the water discharge according to the pressure change in the system, ensure that each drip head can provide a stable flow rate under different pressure conditions, ensure irrigation uniformity, and improve the growth effect of crops. And through the combination of ultrasonic vibration and the eddy current formed by the hemispherical groove, a continuous disturbance and cleaning effect is formed inside the drip head. Ultrasonic vibration can effectively peel off impurities and salts attached to the inner wall, and the eddy current formed by the hemispherical groove can carry these impurities out of the drip head to prevent secondary deposition.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the present invention provides the following technical solution: An efficient energy-saving drip irrigation system, comprising a reservoir, an external centrifugal water pump is fixed to the reservoir, a water outlet of the centrifugal water pump is connected to a filter, a water outlet of the filter is connected to a main pipeline, and a plurality of drip irrigation modules are radially connected to the main pipeline; wherein the reservoir is used to store water source and provide a stable water source for the whole drip irrigation system. The reservoir can be an underground or ground container, and can have different sizes and shapes according to needs. The centrifugal water pump is installed outside the reservoir, and its function is to pump out the water in the reservoir and transport it to the filter through a pipeline. The centrifugal water pump can provide a stable and adjustable flow rate and pressure to ensure that the water can reach other parts of the drip irrigation system. The filter is connected to the water outlet of the centrifugal water pump, and its function is to filter out impurities and particulate matters in the water, prevent these substances from blocking the micropores in the drip irrigation module, ensure smooth water flow and protect downstream equipment. The main pipeline is the main water conveyance pipeline connecting the filter and a plurality of drip irrigation modules. It is responsible for evenly distributing the filtered water to each drip irrigation module. The drip irrigation module is a device connected to the main pipeline, and it is directly responsible for supplying water to the roots of plants. Each drip irrigation module contains a plurality of drippers, which drip water to the vicinity of the roots of crops at a very low flow rate to reduce water evaporation and improve water use efficiency.

[0008] The drip irrigation module includes a connecting head, a drip irrigation bracket is connected to the end of the connecting head, a drip irrigation head is fixedly connected to the left side of the drip irrigation bracket, and an ultrasonic generator is fixedly connected to the right side of the drip irrigation bracket; wherein the main function of the connecting head is to connect the main pipeline and the drip irrigation bracket to ensure that water flow can smoothly enter the drip irrigation bracket from the main pipeline. The drip irrigation bracket is used to fix and support the drip irrigation head and the ultrasonic generator. The drip irrigation head is the component directly responsible for supplying water to the roots of crops. It drips water at a low speed and high frequency to meet the water requirements of crops. The ultrasonic generator is installed on the drip irrigation bracket and is mainly used to prevent the drip irrigation head from being blocked by impurities in the water. It emits ultrasonic vibrations to disperse minerals and other sediments that may accumulate in the water, thereby keeping the water flow unobstructed. The application of this technology significantly improves the reliability and maintenance cycle of the drip irrigation system, reduces maintenance costs and labor requirements.

[0009] The middle part of the drip emitter is a hollow sphere. An inlet liquid flow channel and an outlet liquid flow channel are respectively arranged through both ends. A plurality of hemispherical grooves are arranged in an array on the inner wall of the spherical shape of the drip emitter. An annular fixing groove is arranged inside the drip emitter, and an elastic diaphragm is clamped on the fixing groove. A pressure compensation head is fixed in the middle of the elastic diaphragm. Among them, the middle part of the drip emitter is a hollow spherical structure, providing sufficient internal space for installing other functional components while maintaining smooth water flow. The spherical design can evenly distribute the internal pressure, reduce the turbulence and resistance of the water flow, and ensure the smooth flow of the water through the drip emitter. The inlet liquid flow channel is used to introduce irrigation water, and the outlet liquid flow channel is used to output the water flow to the roots of plants. The plurality of hemispherical grooves on the inner wall of the spherical shape of the drip emitter are used to generate eddy currents. The tiny eddy currents formed when the water flow passes through the grooves can disturb the water flow and prevent impurities from depositing on the inner wall. The formation of the eddy currents helps to carry out the peeled impurities out of the drip emitter, keep the inside clean, and reduce the risk of blockage. The annular fixing groove is used to fix the elastic diaphragm. The elastic diaphragm deforms according to the change of the internal water pressure, adjusts the cross-sectional area of the water flow channel, and realizes the pressure compensation function. The elastic deformation of the diaphragm can form a periodic vibration in the water flow, prevent impurities from depositing on the surface of the diaphragm, and has a certain self-cleaning effect. The pressure compensation head is fixed in the middle of the elastic diaphragm. When the water pressure increases, the pressure compensation head reduces the cross-sectional area of the water flow channel through the deformation of the diaphragm and reduces the water flow speed; when the water pressure decreases, it increases the cross-sectional area of the channel to maintain a constant flow rate. Precise control: By adjusting the design parameters of the pressure compensation head, the water output of each drip emitter can be precisely controlled to ensure the uniformity of the entire irrigation system.

[0010] Preferably, a return flow cavity is arranged on the left side of the drip emitter, and a plurality of guiding grooves are arranged on the inner wall of the return flow cavity. The return flow cavity is arranged on the left side of the drip emitter. The design purpose is to provide an additional flow space during the drip irrigation process, so that the impurities and sediments in the water flow can be effectively discharged from the drip emitter. The design of the guiding grooves can enable the water flow to form a specific flow path when passing through the ultrasonic generator, optimize the action of the ultrasonic wave on the water flow, improve the cleaning effect of the ultrasonic wave, and prevent the deposition of salts and impurities in the drip emitter.

[0011] Preferably, serrated snap rings are arranged in an array on the outer side of the inlet liquid flow channel of the drip emitter. The design of the serrated snap rings can ensure a more firm connection between the drip emitter and the pipeline. The serrated shape provides more contact points and frictional force, preventing the drip emitter from loosening or falling off when subjected to water flow pressure or external force.

[0012] Preferably, the elastic diaphragm is circular as a whole, with a mounting hole provided at its axis, and multiple elastic blades radiating from the axis to the edge of the elastic diaphragm. The elastic diaphragm, as the core component of the pressure compensation system, adjusts the water pressure inside the drip irrigation head through its own elastic deformation to ensure a constant water output under different pressure conditions. The circular design and the central mounting hole ensure that the diaphragm can be accurately fixed on the annular fixing groove inside the drip irrigation head. The mounting hole is used to fix the pressure compensation head to achieve precise pressure compensation. The elastic blades radiate from the axis to the edge of the diaphragm. When the internal water pressure changes, the blades can flexibly deform to adjust the cross-sectional area of ​​the water flow channel to maintain a stable water flow output.

[0013] Preferably, the elastic blade is narrower near the axis of the elastic diaphragm and wider at the outer end. This design enables the blade to have a larger elastic range during deformation, improving the response speed to pressure changes and the adjustment accuracy. The blade with a polygonal structure can disperse the pressure more evenly when subjected to force, reduce stress concentration, and extend the service life of the diaphragm.

[0014] Preferably, the pressure compensating head is cylindrical in shape and has a chamfer at the lower end. The chamfer design can reduce the resistance of water flow through the pressure compensating head. By reducing the resistance, the water flow can pass through the pressure compensating head more smoothly, thereby reducing energy loss and improving irrigation efficiency. Preventing blockage: The chamfer design can make the water flow smoothly transition when passing through the compensating head, reducing the rapid changes and turbulence of the water flow. This helps prevent impurities from accumulating at the lower end of the compensating head and reduce the risk of blockage.

[0015] Preferably, a rubber gasket is provided between the ultrasonic generator and the reflux chamber for sealing to prevent water from overflowing.

[0016] Preferably, a pressure regulating valve is provided at the connection between the drip irrigation module and the main pipeline. The pressure regulating valve is provided at the connection between the drip irrigation module and the main pipeline to adjust the water flow pressure entering the drip irrigation module. By controlling the pressure, it can be ensured that each dripper can drip water at an appropriate rate, thereby avoiding over-irrigation due to excessive pressure or insufficient irrigation due to low pressure.

[0017] Furthermore, a solar panel may be provided on the upper end of the ultrasonic generator.

[0018] (III) Beneficial effects

[0019] The object of the present invention is to provide an efficient and energy-saving drip irrigation system. The efficient and energy-saving drip irrigation system provided by the present invention effectively prevents the clogging of drip irrigation heads by combining ultrasonic anti-clogging technology and pressure compensation technology, ensuring that each drip irrigation head provides a stable irrigation flow under different pressure conditions, thereby guaranteeing the irrigation uniformity. The system is reasonably designed, compact in structure, adopts modular components, is convenient for installation and maintenance, and reduces the operation and maintenance costs. This system is particularly suitable for areas with complex terrain and unstable water source conditions, achieving efficient, energy-saving and reliable agricultural irrigation, and significantly improving the agricultural production efficiency and resource utilization rate.

DETAILED DESCRIPTION OF THE INVENTION

[0029] The following will be combined with the attached drawings in the examples of the present invention Figures 1 - 8The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] The present invention provides a technical solution: an efficient energy-saving drip irrigation system, as Figure 1 shown, which includes a water storage tank 1. A centrifugal water pump 2 is fixed on the outer side of the water storage tank 1. The water outlet of the centrifugal water pump 2 is connected to a filter 3. The water outlet of the filter 3 is connected to a main pipeline 4. It is characterized in that multiple groups of drip irrigation modules 5 are radially connected to the main pipeline 4; a pressure regulating valve 6 is arranged at the connection between the drip irrigation module 5 and the main pipeline 4.

[0031] Among them, the water storage tank 1 is used to store water sources and provide stable water sources for the entire drip irrigation system. The water storage tank can be an underground or ground container, and can have different sizes and shapes according to needs. The centrifugal water pump 2 is installed on the outer side of the water storage tank 1, and its function is to pump the water in the water storage tank and transport it to the filter through a pipeline. The centrifugal water pump 2 can provide stable and adjustable flow rate and pressure to ensure that the water can reach other parts of the drip irrigation system. The filter 3 is connected to the water outlet of the centrifugal water pump 2, and its function is to filter out impurities and particulate matters in the water to prevent these substances from blocking the micropores in the drip irrigation module and ensure smooth water flow and protect downstream equipment. The main pipeline 4 is the main water conveyance pipeline connecting the filter 3 and multiple groups of drip irrigation modules 5. It is responsible for evenly distributing the filtered water to each drip irrigation module. The drip irrigation modules 5 are devices connected to the main pipeline 4, and they are directly responsible for supplying water to the roots of plants. Each drip irrigation module contains multiple drip heads, which drip water near the roots of crops at a very low flow rate to reduce water evaporation and improve water utilization efficiency. The pressure regulating valve 6 is arranged at the connection between the drip irrigation module and the main pipeline to adjust the water flow pressure entering the drip irrigation module. By controlling the pressure, it can ensure that each dripper can drip water at an appropriate rate, thereby avoiding over-irrigation caused by too high pressure or under-irrigation caused by too low pressure.

[0032] As Figure 2As shown, the drip irrigation module 5 includes a connecting head 51. At the end of the connecting head 51, a drip irrigation bracket 52 is connected. On the left side of the drip irrigation bracket 52, a drip irrigation head 53 is fixedly connected, and on the right side of the drip irrigation bracket 52, an ultrasonic generator 54 is fixedly connected. The main function of the connecting head 51 is to connect the main pipeline and the drip irrigation bracket, ensuring that water can flow smoothly from the main pipeline into the drip irrigation bracket. It usually has good sealing performance to prevent water leakage at the connection, and at the same time allows for quick installation and disassembly for easy maintenance and replacement. The drip irrigation bracket 52 is used to fix and support the drip irrigation head and the ultrasonic generator. Its design needs to ensure sufficient stability to ensure that the drip irrigation head can accurately drip water droplets to the root area of the crop. At the same time, the drip irrigation bracket should be able to adapt to different crop row spacings and terrain changes to provide flexible irrigation solutions. The drip irrigation head 53 is the component directly responsible for supplying water to the crop roots. They usually have tiny water outlet holes or channels to drip water at a low speed and high frequency to meet the water requirements of the crop. The design of the drip irrigation head should be able to reduce losses caused by evaporation and splashing, and have good anti-blocking performance to cope with possible water quality problems. The ultrasonic generator 54 is installed on the drip irrigation bracket and is mainly used to prevent the drip irrigation head from being blocked by impurities in the water. It emits ultrasonic vibrations to break up minerals and other sediments that may accumulate in the water, thus keeping the water flow unobstructed. The application of this technology significantly improves the reliability and maintenance cycle of the drip irrigation system, reducing maintenance costs and labor requirements.

[0033] As Figure 3 shown, the middle part of the drip irrigation head 53 is a hollow sphere. An inlet liquid flow channel 531 and an outlet liquid flow channel 532 are respectively arranged through both ends. A plurality of hemispherical grooves 533 are arranged in an array on the spherical inner wall of the drip irrigation head 53. An annular fixing groove 534 is arranged inside the drip irrigation head 53, and an elastic diaphragm 535 is clamped on the fixing groove 534. A pressure compensation head 536 is fixed in the middle of the elastic diaphragm 535.

[0034] Among them, the middle part of the drip head 53 is a hollow spherical structure, providing sufficient internal space for installing other functional components, such as an elastic diaphragm and a pressure compensation head, while maintaining smooth water flow. Hydrodynamics: The spherical design can evenly distribute the internal pressure, reduce the turbulence and resistance of the water flow, and ensure the smooth flow of the water through the drip head. The liquid inlet channel 531 is used to introduce irrigation water, and the liquid outlet channel 532 is used to output the water flow to the roots of plants. By optimizing the diameter and shape of the channels, the amount of water entering and leaving can be precisely controlled to ensure uniform irrigation for each drip head. The multiple hemispherical grooves 533 on the spherical inner wall of the drip head 53 are designed to generate eddy currents. The tiny eddy currents formed when the water flow passes through the grooves can disturb the water flow, prevent impurities from depositing on the inner wall. The formation of eddy currents helps to carry out the stripped impurities out of the drip head, keep the inside clean, and reduce the risk of blockage. The annular fixing groove 534 is used to fix the elastic diaphragm 535 to ensure the stability of the diaphragm inside the drip head. The fixing groove can effectively fix the elastic diaphragm, prevent it from moving or falling off, and ensure that the diaphragm can work properly. The elastic diaphragm 535 deforms according to the change of the internal water pressure, adjusts the cross-sectional area of the water flow channel, and realizes the pressure compensation function. The elastic deformation of the diaphragm can form periodic vibrations in the water flow, prevent impurities from depositing on the surface of the diaphragm, and has a certain self-cleaning effect. The pressure compensation head 536 is fixed in the middle of the elastic diaphragm. When the water pressure increases, the pressure compensation head reduces the cross-sectional area of the water flow channel through the deformation of the diaphragm, reducing the water flow speed; when the water pressure decreases, it increases the channel cross-sectional area to maintain a constant flow rate. Precise control: By adjusting the design parameters of the pressure compensation head, the water output of each drip head can be precisely controlled to ensure the uniformity of the entire irrigation system.

[0035] A return cavity 537 is provided on the left side of the drip head 53. Multiple guiding grooves 538 are provided on the inner wall of the return cavity 537. The return cavity 537 is arranged on the left side of the drip head 53. The design purpose is to provide an additional flow space during the drip irrigation process, so that impurities and sediments in the water flow can be effectively discharged from the drip head. The design of the guiding grooves 538 can enable the water flow to form a specific flow path when passing through the ultrasonic generator 54, optimize the effect of ultrasonic waves on the water flow, improve the cleaning effect of ultrasonic waves, and prevent the deposition of salts and impurities in the drip head. Concentrate ultrasonic energy: The guiding grooves can help concentrate ultrasonic energy in a specific area, making the cleaning effect of ultrasonic waves more concentrated and effective, and improving the cleaning efficiency. The guiding grooves can help balance the water pressure distribution inside the drip head, avoid excessive or too low pressure on one side of the water flow, and ensure the stable operation of the drip irrigation system under different pressure conditions. By guiding the water flow, the guiding grooves can reduce the direct impact and wear of the water flow on the internal structure of the drip head, and extend the service life of the drip head.

[0036] The outer side of the liquid inlet channel 531 of the drip irrigation head 53 is provided with a sawtooth clamp ring 539 in an array. The design of the sawtooth clamp ring can ensure a more secure connection between the drip irrigation head and the pipeline. The sawtooth shape provides more contact points and friction to prevent the drip irrigation head from loosening or falling off when subjected to water pressure or external force.

[0037] like Figure 6 As shown, the elastic diaphragm 535 is circular as a whole, and a mounting hole 5351 is provided at its axis. A plurality of elastic blades 5352 are radiated from the axis of the elastic diaphragm 535 to the edge. The elastic blade 5352 is in the shape of a polygon with a narrow inner end and a wide outer end. As the core component of the pressure compensation system, the elastic diaphragm 535 adjusts the water pressure inside the drip irrigation head through its own elastic deformation to ensure a constant water output under different pressure conditions. Sealing function: The circular design and the central mounting hole 5351 ensure that the diaphragm can be accurately fixed on the annular fixing groove 534 inside the drip irrigation head. The mounting hole 5351 is used to fix the pressure compensation head 536 to achieve precise pressure compensation. The elastic blade 5352 radiates from the axis of the diaphragm to the edge. When the internal water pressure changes, the blade can flexibly deform, adjust the cross-sectional area of ​​the water flow channel, and maintain a stable water flow output. Advantages of shape design: The shape of the elastic blade is designed as a polygon with a narrow inner end and a wide outer end. This design enables the blade to have a larger elastic range during the deformation process, improves the response speed and adjustment accuracy to pressure changes. The polygonal blade structure can disperse the pressure more evenly when subjected to force, reduce stress concentration and extend the service life of the diaphragm.

[0038] The pressure compensating head 536 is cylindrical in shape, with a chamfer at the lower end. The chamfer design can reduce the resistance of water flowing through the pressure compensating head. By reducing the resistance, water can flow more smoothly through the pressure compensating head, thereby reducing energy loss and improving irrigation efficiency. Preventing clogging: The chamfer design can make the water flow smoothly transition when passing through the compensating head, reducing the sudden change of water flow and turbulence. This helps prevent impurities from accumulating at the lower end of the compensating head and reduce the risk of clogging.

[0039] The working principle of the present invention can be specifically divided into the following stages:

[0040] 1. Extraction and filtration of irrigation water: The irrigation water in the reservoir 1 is extracted by a centrifugal pump 2. During the pumping process, the centrifugal pump pressurizes the water and sends it into the system. The pressurized water passes through the filter 3, during which the filter filters out large particles and pollutants, ensuring that the water entering the main pipeline 4 is relatively pure.

[0041] 2. Water flows into the drip irrigation module: The filtered water enters the main pipeline 4 and is then transported to the drip irrigation heads 53 in the plurality of drip irrigation modules 5 through the pipeline. The water first enters the drip irrigation head 53 through the liquid inlet channel 531 .

[0042] 3. Pressure regulation mechanism:

[0043] Under high water pressure conditions: When the water pressure is relatively high, the liquid entering the drip emitter impacts the elastic diaphragm 535. The elastic diaphragm deforms under pressure, driving the pressure compensation head 536 fixed on it to move slightly towards the liquid outlet channel 532, reducing the cross-sectional area of the liquid outlet channel, thereby reducing the flow rate of the liquid outlet and achieving the purpose of reducing the flow rate.

[0044] Under low water pressure conditions: When the water pressure is relatively low, the elastic diaphragm rebounds due to its own elasticity, driving the pressure compensation head to retract. This retraction restores the cross-sectional area of the liquid outlet channel to the normal level, ensuring the normal drip irrigation flow rate. Prevention of salt crystallization and blockage:

[0045] Prevention of salt crystallization and blockage: During long-term drip irrigation, salts in the water are prone to crystallize at the drip emitter, resulting in blockage. The system is designed with an ultrasonic generator 54, whose transmitting end penetrates to the middle of the drip emitter 53. When the ultrasonic generator works, the generated ultrasonic waves can vibrate the hemispherical groove 533 inside the drip emitter, forming tiny eddies in the water flow. These eddies increase the self-cleaning ability of the water flow, disrupt the salt crystallization process, and prevent the formation of salt crystals.

[0046] Combined design of comprehensive anti-blocking function: The combined design of ultrasonic waves and the hemispherical groove 533 inside the drip emitter ensures the formation of effective eddies during drip irrigation, preventing the deposition of salts and impurities. The combined action of ultrasonic vibration and eddy current effect keeps the water flow inside the drip emitter in a dynamically clean state, preventing blockage, and improving the reliability and service life of the system.
