Description

Technical Field

[0001] This utility model relates to the field of irrigation technology for Chinese medicinal materials, and in particular to an intelligent water-saving irrigation device for Chinese medicinal materials. Background Technology

[0002] With the accelerated pace of large-scale and standardized cultivation of Chinese medicinal herbs, the contradiction between the adaptability of irrigation technology and the efficiency of resource utilization is becoming increasingly prominent, as irrigation is a core link affecting the quality, yield, and planting benefits of medicinal herbs. The industry's demand for specialized irrigation solutions is becoming increasingly urgent. From a planting perspective, Chinese medicinal herbs are diverse and have significantly different growth characteristics. Rhizome-type herbs (such as Salvia miltiorrhiza and Astragalus membranaceus) require avoiding waterlogging at the roots to prevent rot and necessitate ensuring sufficient moisture in the shallow soil around the roots. Leafy herbs (such as peppermint and Artemisia argyi) require maintaining leaf moisture to promote photosynthesis, but also need to control the amount of water on the leaves to prevent disease. Even for the same herb, seedlings require frequent, small-volume watering to prevent waterlogging, mature plants require sufficient water to promote growth, and the harvest period requires appropriate water control to maintain quality. Traditional flood irrigation or fixed-nozzle irrigation with uniform timing and volume cannot accurately meet these differentiated needs, often leading to insufficient accumulation of effective components or reduced yield. From a resource utilization perspective, the main production areas of Chinese medicinal herbs are mostly concentrated in mountainous and hilly areas, which have limited water resources. Traditional irrigation methods generally have a water utilization rate of less than 50%, with a large amount of water wasted due to evaporation and seepage. More importantly, traditional irrigation systems lack pressure control mechanisms. When the planting area is too large or the pipeline length is too long, excessive pressure near the water source can lead to over-irrigation, while areas further away from the water source may experience insufficient water output or even no water at all due to pressure decay, further exacerbating the contradiction between water supply and demand and uneven irrigation. From a management efficiency perspective, as the scale of planting bases expands, the traditional method of relying on manual inspection of soil moisture, manual valve switching, and individual sprinkler head adjustment is not only extremely inefficient—inspection and adjustment per acre before and after a single irrigation takes 1-2 hours—but also prone to errors in human judgment, leading to irrigation being too early or too late, or too much or too little water, directly affecting the growth of medicinal herbs. At the same time, the cost of manual management is rising year by year, accounting for 15%-20% of the total cost of large-scale planting, becoming a significant factor restricting the improvement of planting efficiency.

[0003] To address the aforementioned issues, a smart water-saving irrigation device for Chinese medicinal herbs is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an intelligent water-saving irrigation device for greenhouse medicinal herbs, which solves the technical problems of traditional irrigation devices being unable to irrigate in zones, having high water consumption and inaccurate spraying in flood irrigation and sprinkler irrigation, and experiencing water pressure fluctuations in the irrigation network due to pump shutdowns.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smart water-saving irrigation device for Chinese medicinal herbs includes a ring pipe, on which a water inlet component and a set of pressure branch pipe components are installed. The water inlet component includes a T-type multi-stage filter, a solenoid valve and a simple flow regulating valve.

[0007] Each pressure-dividing branch pipe assembly includes a pressure-dividing branch pipe, a mechanical pointer soil moisture meter, and a stratified spraying assembly. Each stratified spraying assembly includes a top wide-angle nozzle, a middle narrow-angle nozzle, a bottom micro-nozzle, and a height-adjustable bracket with three water outlet branches. The height-adjustable bracket is equipped with a 360-degree rotatable quick-connect fitting on top.

[0008] The annular pipe is fixedly connected to eight annular array of movable flanges;

[0009] A pilot-operated pressure compensation valve is fixedly installed at one end of the pressure distribution branch pipe near the annular pipe. The end of the pilot-operated pressure compensation valve near the annular pipe is connected to the valve flange.

[0010] The stratified spraying assembly features a three-layer height design.

[0011] Preferred: The T-type multi-stage filter, solenoid valve, and simple flow regulating valve are connected to the pipeline by pre-welding internal threads through their own external threads.

[0012] Preferred configuration: The distance between the pressure-distributing branch pipe and the ring pipe smoothly decreases from 75mm to 50mm to compensate for pressure attenuation;

[0013] The pilot-operated pressure compensation valve installed between the valve flange and the pressure-dividing branch pipe is set with a target pressure of 0.2MPa. When the pressure in the annular pipe is >0.25MPa, it automatically releases pressure, and when it is <0.15MPa, it closes the branch.

[0014] Preferably, the height-adjustable support main rod includes a fixed section, an adjustment section one, and an adjustment section two;

[0015] An arc-shaped support plate is welded to the lower part of the fixed section. A water outlet branch is provided on the arc-shaped support plate. The lowest layer micro-sprinkler is connected to the water outlet branch through a snap-fit ​​quick-connect interface.

[0016] The first adjustment section is nested inside the fixed section. The bottom is welded with an anti-slip rubber ring. The upper middle part is provided with the second water outlet branch. The top is connected to the second adjustment section. The second water outlet branch is connected to the middle layer narrow angle nozzle.

[0017] Adjustment section two is nested inside adjustment section one, with an anti-slip rubber ring welded to the bottom and a 360-degree rotatable quick-connect connector installed on the top. The upper end of the 360-degree rotatable quick-connect connector is connected to the top wide-angle nozzle.

[0018] Preferred: The 360-degree rotatable quick connector consists of a connector body, a deep groove ball bearing, a sealing ring, and guide vanes. The guide vanes are integrated with the connector body in the upper part of the connector body. The connector body is provided with a deep groove ball bearing in the middle. The connector body is provided with a sealing ring at the bottom and upper part. The 360-degree rotatable quick connector is connected to the adjustment section two in the height-adjustable bracket by bolts.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By using a pilot-operated pressure compensation valve to stabilize the target water pressure at 0.2MPa and a smooth 75mm to 50mm diameter change in the pressure distribution branch pipe to compensate for pressure attenuation, water waste caused by pressure fluctuations is avoided. Combined with three layers of differentiated sprinklers (bottom layer for micro-irrigation of roots, middle layer for narrow-angle irrigation of leaves, and top layer for wide-angle irrigation of stems) and eight independent irrigation zones, the system precisely addresses the different water requirements of different types (root and rhizome, leaf) and growth stages (seedling stage, mature stage) of Chinese medicinal herbs. This significantly improves water utilization compared to traditional irrigation and avoids problems such as "waterlogged roots and dry leaves," ensuring the quality and yield of medicinal herbs.

[0021] Meanwhile, the device can reduce management costs and is adaptable to various greenhouse scenarios: the solenoid valve automatically opens and closes, and the flow metering module monitors water consumption in real time, replacing manual valve switching and recording. With convenient structures such as quick-connect sprinklers and flange interfaces, it greatly reduces manual intervention and maintenance time, thus lowering management costs. The ring pipe can be adjusted according to the greenhouse area, the length of the pressure-distributing branch pipes can be customized, and it can also be modified into a stepped type to adapt to slopes and extended supports to adapt to multi-layered planting, fully meeting the irrigation needs of various greenhouse medicinal herbs.

[0029] This application provides a semi-automatic fixed sprinkler irrigation device for greenhouses, which effectively solves the technical problems of low water resource utilization efficiency, inability to accurately match the differentiated irrigation needs of Chinese medicinal herbs, and high and inaccurate manual irrigation by providing a semi-automatic fixed sprinkler irrigation device.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the technical solution in this application embodiment effectively solves the problems of traditional irrigation devices being unable to irrigate in zones, wasting water resources due to sprinkler and flood irrigation, and causing pressure fluctuations due to pump start-stop, leading to over-irrigation or water shortage of Chinese medicinal materials. The overall idea is as follows:

[0031] To address the problems existing in the prior art, this utility model provides an intelligent water-saving irrigation device for Chinese medicinal herbs. The device has a core architecture of ring main pipeline + zoned branch irrigation + stratified spraying. The core components include a ring pipeline 1, a water inlet assembly 6, a pressure-dividing branch pipeline assembly, a stratified spraying assembly, a pilot-operated pressure compensation valve 12, and a mechanical pointer-type soil moisture meter 8. The structure and function of each component are as follows:

[0032] The ring pipe 1 is the main channel for water distribution. It is made of corrosion-resistant plastic and has eight ring array of movable flanges 14 fixedly connected to it, which facilitates the installation and replacement of the pressure-reducing branch pipes 2.

[0033] Water inlet assembly 6 is the pretreatment and main control unit of the water source entry device. It is connected in series at the water inlet end of the ring pipe 1 and consists of a T-type multi-stage filter 9, a solenoid valve 10, and a simple flow regulating valve 11. The three components are sealed together by their own external threads and the internal threads pre-welded to the pipe to prevent water leakage at the interface.

[0034] T-type multi-stage filter 9: Built-in 200-mesh filter and activated carbon filter layer, which can filter mud, impurities and small particles in the water source, prevent clogging of subsequent nozzles and valves, and ensure smooth irrigation;

[0035] Solenoid valve 10: As the main switch of the device, it can be automatically opened and closed by an external controller (such as a timer or humidity linkage module), replacing manual switching and reducing management costs;

[0036] Simple flow regulating valve 11: By rotating the valve stem to adjust the valve core opening, the total water volume entering the annular pipe 1 can be controlled (adjustment range 0-5m³ / h), adapting to the irrigation needs of different seasons (reduced flow in rainy season, increased flow in dry season) or different planting scales.

[0037] The pressure-distributing branch pipeline assembly is the core of the zoned irrigation system, consisting of 8 groups (corresponding to 8 adjustable flanges 14). Each group independently controls one irrigation zone, enabling differentiated irrigation for different plots and medicinal herbs. Each group includes 2 pressure-distributing branch pipelines, 12 pilot-operated pressure compensation valves, and 8 mechanical pointer-type soil moisture meters.

[0038] Pressure distribution branch pipe 2: It adopts a variable diameter design, with a diameter of 75mm from the starting end of the ring pipe 1, and gradually and smoothly changes to 50mm towards the end. The change in pipe diameter compensates for the pressure drop during water transportation and ensures that there is still stable water pressure at the end of the pipe. The outer wall of the pipe is wrapped with a black anti-aging coating to extend its service life.

[0039] Pilot-operated pressure compensation valve 12: Installed between the pressure-dividing branch pipe 2 and the valve flange 14, it is a zone water pressure stabilizer: The target working pressure is set to 0.2MPa. When the pressure in the annular pipe 1 is >0.25MPa, the valve automatically opens the pressure relief port to prevent high pressure from damaging the nozzles; when the pressure is <0.15MPa, the valve automatically closes the branch channel to prevent insufficient water output from the nozzles due to low pressure.

[0040] Mechanical pointer-type soil moisture meter 8: buried in the soil near the pressure branch pipe 2 (the depth matches the root depth of Chinese medicinal materials, 20cm for root and rhizome medicinal materials and 10cm for leaf medicinal materials), the soil moisture is displayed intuitively by the deflection of the pointer (range 0-100%RH), providing a basis for irrigation timing (irrigation is started when the pointer points to the "dry zone" and stopped when it points to the "wet zone").

[0041] The stratified spraying system is designed to address the different water requirements of different parts of the medicinal herb. It adopts a three-layer height-adjustable structure, and the height-adjustable bracket 7 enables precise irrigation of the roots, middle leaves, and upper plant. Each set of pressure branch pipes 2 corresponds to one set of stratified spraying components.

[0042] Height-adjustable bracket 7: The main rod of the bracket is a three-section nested steel pipe (fixed section 16, adjustable section one 17, and adjustable section two 18), made of aluminum alloy, which is lightweight and corrosion-resistant. It can be adjusted by nesting length to accommodate Chinese medicinal herbs of different growth heights and can be fixed using common bolts.

[0043] Fixed section 16: The bottom is welded with an inverted conical buried base to ensure that the support is stable and does not tilt; the middle and lower part is welded with an arc-shaped support plate, and the support plate is reserved with a water outlet branch 23 for connecting the bottom nozzle;

[0044] Adjustment section 17: nested inside the fixed section 16, with an anti-slip rubber ring glued to the bottom (to increase nesting friction and prevent it from sliding down on its own); water outlet branch 24 is reserved in the upper middle part for connecting the middle layer nozzle;

[0045] Adjustment section 2 18: nested inside adjustment section 1 17, with an anti-slip rubber ring also bonded to the bottom; bolt holes are reserved at the top for installing the 360-degree rotatable quick connector 15.

[0046] The three-layer bracket corresponds to three different types of nozzles, and is connected via quick-connect / threaded connections for easy disassembly and replacement.

[0047] The lowest layer micro-sprinkler 5: It is connected to the water outlet branch 23 through a snap-fit ​​quick-connect interface. The spraying method is drip irrigation + micro-mist, which directly supplies water to the roots of Chinese medicinal materials (such as the roots of Salvia miltiorrhiza and Astragalus membranaceus) to avoid water waste.

[0048] Mid-layer narrow-angle nozzle 4: Connects to water outlet branch 24 via a snap-fit ​​quick-connect interface, spraying angle 30-60° (narrow-angle orientation), targeting the middle leaves of Chinese medicinal herbs (such as mint and artemisia leaves), avoiding prolonged water accumulation on the leaf surface that could lead to disease;

[0049] Top wide-angle nozzle 3: Connected to the adjustment section 2 18 via a 360-degree rotatable quick-connect connector 15, spraying angle 120-180° (wide-angle coverage), irrigating the upper layer of medicinal plants (such as the stems and vines of vine-type medicinal plants).

[0050] 360° rotatable quick-connect connector 15: Composed of connector body 19, deep groove ball bearing 20, sealing ring 21, and guide vane 22: The guide vane 22 is integrated with the connector body 19. When water flows through, it pushes the vane to rotate, causing the connector body 19 to rotate around the deep groove ball bearing 20, realizing 360° rotation spraying of the nozzle (single nozzle coverage area 5-8㎡); the sealing ring 21 is made of nitrile rubber to prevent water leakage when the connector rotates; the connector is fixed to the adjustment section 2 18 by bolts, and the nozzle can be replaced by simply unscrewing the bolts when disassembling.

[0051] Working principle:

[0052] The irrigation process of the device follows the logic of pretreatment → partial pressure → monitoring → precision spraying, and the specific steps are as follows:

[0053] Water source pretreatment and overall control:

[0054] Irrigation water (well water, reservoir water) first enters the water inlet component 6: after impurities are filtered by the T-type multi-stage filter 9, the solenoid valve 10 opens according to the preset command (or soil moisture signal), and the simple flow regulating valve 11 adjusts to the target total flow. The treated clean water enters the ring pipe 1.

[0055] Zoned pressure and flow monitoring:

[0056] Clean water is evenly distributed to eight hinged flanges 14 within the annular pipe 1. The pilot-operated pressure compensation valve 12 at each hinged flange 14 automatically regulates the water pressure: when the pressure in the annular pipe 1 is >0.25MPa, the valve releases pressure; when the pressure is <0.15MPa, the valve closes the branch, ensuring that the water pressure in each pressure branch pipe 2 is stable at around 0.2MPa.

[0057] Soil moisture monitoring and irrigation triggering:

[0058] The mechanical pointer-type soil moisture meter 8 monitors the soil moisture of the corresponding zone in real time: when the moisture is lower than the threshold required for the growth of Chinese medicinal materials (60%RH for rhizomes and 70%RH for leaves), the manual or automatic controller triggers the irrigation process of the zone (opens the secondary valve of the pressure branch pipe 2, and can directly link the solenoid valve 10 when the intelligent module is integrated).

[0059] Layered precision spraying:

[0060] After the water flows into the pressure-dividing branch pipe 2, it is distributed to different nozzles through the three water outlet branches of the height-adjustable bracket 7: the lowest layer micro-sprinkler 5 drips water to the roots, the middle layer narrow-angle sprinkler 4 sprays water directionally to the leaves, and the top wide-angle sprinkler 3 rotates 360° to cover the upper plants under the action of the guide blades 22; the height of the bracket can be adjusted according to the growth stage of the Chinese medicinal materials (30cm for seedlings and 120cm for mature plants) to ensure that the spraying position matches the needs of the crop.

[0061] Irrigation Stoppage and System Maintenance:

[0062] When the soil moisture meter shows that the humidity has reached the target value (or the preset irrigation time has ended), the solenoid valve 10 closes and irrigation stops; the filter screen of the T-type multi-stage filter 9 is cleaned regularly to avoid clogging; the subsequent irrigation volume is optimized by the data from the flow metering module (if the water consumption of a certain zone is abnormal, check the nozzle blockage or valve failure).

[0063] Working principle:

[0064] In the first step, irrigation water enters the inlet component 6 and is filtered by the T-type multi-stage filter 9 to remove impurities and prevent clogging of the sprinkler heads. The solenoid valve 10 controls the water supply to the entire device, and the simple flow regulating valve 11 connects to the internal thread of the pipe through the external threads of the valve body inlet and outlet, which can regulate the total amount of water entering the annular pipe to meet different irrigation needs.

[0065] In the second step, the treated water enters the annular pipe 1, which is connected to pressure-distributing branch pipes via eight annular array flanges 14. A pilot-operated pressure compensation valve 12 at the interface between the flanges 14 and the pressure-distributing branch pipes 2 is set to a target pressure of 0.2 MPa. When the pressure in the annular pipe exceeds 0.25 MPa, it automatically releases pressure; when it falls below 0.15 MPa, the branch pipe closes, ensuring stable water pressure in each branch pipe. Simultaneously, the flow metering module integrated within the pilot-operated pressure compensation valve 12 monitors the water consumption of each zone in real time. Furthermore, the distance between the pressure-distributing branch pipes 2 and the annular pipe 1 smoothly decreases from 75 mm to 50 mm to compensate for pressure attenuation and ensure efficient water delivery.

[0066] The third step involves burying mechanical pointer-type soil moisture meters 8 in the soil near each pressure-dividing branch pipe 2 to monitor soil moisture in real time. When the soil moisture is detected to be lower than the threshold required for the growth of medicinal herbs, the relevant control mechanism is activated, and the irrigation process of the corresponding pressure-dividing branch pipe is started.

[0067] The fourth step involves the adjustable support 7, whose main rod is a three-section nested steel pipe, allowing for height adjustment of the spraying height according to the growth height of the medicinal herbs. The 360-degree rotatable quick-connect connector 15 at the top of the second adjustable section 18 connects to the top wide-angle sprinkler 3. The connector body 19 contains a deep groove ball bearing 20. The guide vanes 22 inside the 360-degree rotatable quick-connect connector rotate under the action of water flow, enabling the top wide-angle sprinkler 3 to rotate and spray 360 degrees, expanding the irrigation range. The middle-layer narrow-angle sprinkler 4 connects to the branch pipe on the adjustable support 7 via a snap-fit ​​quick-connect interface, providing directional narrow-range spraying for the middle layer area. The lowest-layer micro-sprinkler 5 connects to the branch pipe via threads, providing precise micro-irrigation near the roots. This three-layer spraying system meets the water needs of different growth parts of the medicinal herbs, achieving water-saving and efficient irrigation.

[0068] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
