Description
Technical Field
[0001] This utility model relates to the field of soil improvement technology, specifically a drip irrigation device for improving saline-alkali soil. Background Technology
[0002] Currently, in response to the characteristics of saline-alkali land, the main measures for improving saline-alkali land at home and abroad include water conservancy projects and physical remediation (irrigation to wash salt, drainage to remove salt, topsoil improvement, land leveling, terrain elevation, deep plowing and loosening, freshwater storage to suppress salt and alkali, irrigation to wash salt and alkali, and underground pipe drainage), chemical and agronomic remediation (crop rotation, polymer soil conditioners, desulfurized gypsum, fly ash, furfural residue, tailings, organic acids, etc.), and bioremediation (selection, introduction, genetic engineering breeding, etc. to select salt-tolerant plants and mycorrhizal fungi).
[0003] In existing technologies, drip irrigation was originally a water-saving irrigation technology for agriculture, and in recent years it has begun to be applied to the remediation of shallow soil pollution. However, when drip irrigation remediation operations are generally carried out, the monitoring of the remediation effect relies on manual sampling, and the operation status of the drip irrigation system needs to be adjusted while waiting for laboratory test results. The feedback cycle is long, and real-time feedback control and adjustment are not possible. In addition, drip irrigation devices are usually soaked in moist soil, which makes them easy to be damaged and has a short service life. Furthermore, the soil moisture evaporates quickly after drip irrigation, making it impossible to achieve long-term and sustained salt control. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4This utility model discloses a drip irrigation device for improving saline-alkali soil, including a storage tank 1. A control mechanism 2 is provided on the front side of the storage tank 1. A stirring component 3 is fixedly installed in the middle of the upper surface of the storage tank 1 to prevent the pesticide from settling. An injection pipe 4 is provided on the upper surface of the storage tank 1. An extraction mechanism 5 is fixedly installed on the left side of the storage tank 1 and is connected to a main pipe 6. Distribution pipes 7 are evenly fixedly installed on the left and right sides of the main pipe 6. Solenoid valves 8 are evenly arranged on the 7. Branch pipes 9 are evenly fixedly installed on the lower surface of the solenoid valves 8. Drip heads 10 are evenly arranged on the four sides of the branch pipes 9. Fixing mechanisms 11 are fixedly installed on the ends of the liquid distribution pipes 7 away from the main pipe 6. A detection mechanism 12 is fixedly installed inside the fixing mechanism 11, and the detection mechanism 12 is wirelessly connected to the control mechanism 2. The branch pipes 9 and the detection mechanism 12 are inserted into the mixed soil 13, which is spaced apart. The mixed soil 13 is buried in the raised ridge 14.
[0023] Specifically, the control mechanism 2 includes a main controller 201 and a first wireless communication module 202. The main controller 201 is installed on the front side of the medicine storage tank 1, and the first wireless communication module 202 is installed on the upper side wall of the main controller 201.
[0024] In this embodiment, the main controller 201 is used to control the opening and closing of the stirring assembly 3, the water pump 501 and the solenoid valve 8. The first wireless communication module 202 is electrically connected to the detection mechanism 12 to receive information. The main controller 201 adopts the DREAM controller produced by TALGIL, with 16-250 bit input / output signal wired connection for local control, single-cable dual-line remote terminal control device (maximum distance up to 10km), and wireless signal transmission (maximum coverage radius of 4km).
[0025] Specifically, the extraction mechanism 5 includes a water pump 501 and a connecting pipe 502. The water pump 501 is installed on the left side of the medicine storage tank 1, and the inlet and outlet of the water pump 501 are connected to the medicine storage tank 1 and the main pipe 6 through the connecting pipe 502, respectively.
[0026] In this embodiment, the water pump 501 draws the medicine from the medicine storage tank 1 into the main pipe 6 through the connecting pipe 502.
[0027] Specifically, the fixing mechanism 11 includes a fixing sleeve 111 and a locking bolt 112. The fixing sleeve 111 is fixedly installed on the end of the liquid distribution pipe 7 away from the main pipe 6, and the fixing sleeve 111 is locked and fixed to the detection mechanism 12 by the locking bolt 112.
[0028] In this embodiment, tightening or loosening the locking bolt 112 causes the detection mechanism 12 to move up and down within the fixing sleeve 111, thereby adjusting the depth of the detection mechanism 12. The locking bolt 112 can lock and fix the fixing sleeve 111 and the detection mechanism 12, thereby fixing the detection mechanism 12.
[0029] Specifically, the detection mechanism 12 includes an installation cylinder 121, a soil integrated sensor 122, a battery 123, a secondary controller 124, a second wireless communication module 125, and a sealing cover 126. The installation cylinder 121 is installed inside the fixing sleeve 111. The soil integrated sensor 122 is installed on the lower surface of the installation cylinder 121. The battery 123, the secondary controller 124, and the second wireless communication module 125 are installed sequentially from bottom to top inside the installation cylinder 121. The sealing cover 126 is threaded onto the upper surface of the installation cylinder 121.
[0030] In this embodiment, the soil integrated sensor 122 detects the pH value, humidity and salinity in the soil, and transmits the detected information to the first wireless communication module 202 through the second wireless communication module 125. The battery 123 provides power to the detection mechanism 12. The soil integrated sensor 122 has three soil sensors, namely a soil pH sensor, a humidity sensor and a salinity sensor. The lower end of the soil integrated sensor 122 is retractable and can penetrate 0.5 to 1.5 meters below the ground surface.
[0031] Specifically, the outer surfaces of the main pipe 6, the liquid distribution pipe 7, the branch pipe 9, and the mounting cylinder 121 are all provided with protective mechanisms 15. The protective mechanism 15 includes a polyester rubber layer 151 and a wire mesh layer 152. The polyester rubber layer 151 and the wire mesh layer 152 are sequentially sleeved and installed on the outer surfaces of the main pipe 6, the liquid distribution pipe 7, the branch pipe 9, and the mounting cylinder 121 from the inside out.
[0032] In this embodiment, the polyester rubber layer 151 and the steel wire mesh layer 152 enhance the corrosion resistance of the main pipe 6, the liquid distribution pipe 7, the branch pipe 9, and the installation cylinder 121, and extend their service life.
[0033] Specifically, the upper surface of the raised ridge 14 is covered with straw 16 and planted with various plants 17.
[0034] In this implementation plan, covering with straw 16 can reduce soil moisture evaporation and prevent the formation of water and salt rising channels in the soil. Planting plants 17 can keep the plant roots in a half-moist and half-dry state, which is conducive to controlling transpiration and saving water. The state of the roots can stimulate and induce the plant to have higher photosynthetic efficiency, which is conducive to increasing yield and income.
[0035] In use, the treated soil is evenly raised into ridges 14, and mixed soil 13 is buried in the ridges 14. The main pipe 6 is then laid on the ridges 14, with branch pipes 9 and drip irrigation heads 10 inserted into the soil on the lower surface of the main pipe 6. Straw 16 is laid on the upper surface of the ridges 14, and seed plants 17 are planted in the mixed soil 13. The soil integrated sensor 122 on the lower surface of the mounting cylinder 121 in the detection mechanism 12 is then inserted into the soil, and the detection mechanism 12 is fixed by locking bolts 112 and fixing sleeves 111. The drip irrigation main controller 201 is pre-set to set the flow rate value of the main pipe 6 and the on / off state of the solenoid valve 8 for soil pH, humidity, and salinity values within a specific range. The soil integrated sensor 122 in the detection mechanism 12 detects the pH, humidity, and salinity values in the soil, and... The detected information is transmitted to the first wireless communication module 202 via the second wireless communication module 125. The first wireless communication module 202 feeds the information back to the main controller 201. The main controller 201 causes the water pump 501 in the extraction mechanism 5 to draw the agent from the storage tank 1 into the main pipe 6 through the connecting pipe 502, and then into the distribution pipe 7 through the main pipe 6. According to the detected information, the corresponding solenoid valve 8 is opened, allowing the agent to flow into the branch pipe 9 and out through the drip irrigation head 10. When the combination of soil pH, humidity, and salinity in the area reaches the set target range, it indicates that the agent in the area has reached the set dosage and depth. The main controller 201 closes the switch of the solenoid valve 8 on the corresponding branch pipe 9. At the same time, the main controller 201 reduces the power of the water pump 501 to reduce the agent delivery flow rate in the main pipe 6. For example, in a shallow hexavalent chromium-contaminated soil, ferrous sulfate is used for remediation. When the pH of a soil integrated sensor 122 is below 5, the humidity reaches 70%, or the soil salinity increases by 3 times compared to the background value, the solenoid valve 8 on the branch pipe 9 is closed, and the power of the water pump 501 is reduced. This system improves the soil composition of the planting area of the plant 17 by mixing the soil 13, thereby increasing the permeability and aeration of the original soil and improving its texture and fertility. At the same time, drip irrigation tapes are set at alternating intervals for drip irrigation, which can allow plant roots to... The system is in a semi-moist, semi-dry state, which is conducive to controlling transpiration and saving water. The root system can stimulate and induce higher photosynthetic efficiency, which is conducive to increasing yield and income. In addition, the drip irrigation uses unconventional water, which can neutralize the acid and alkaline substances in the soil. Furthermore, using straw for mulching can reduce soil moisture evaporation and prevent the formation of water and salt rising channels in the soil, achieving a long-lasting salt control effect. The entire treatment system utilizes unconventional water, straw and other environmental resources, improving resource utilization and reducing treatment costs.
[0036] In summary, this drip irrigation device for saline-alkali soil improvement can detect and provide feedback on soil conditions in real time, thereby enabling drip irrigation based on the detected values, extending the service life of the drip irrigation device, and effectively and accurately treating saline-alkali land in a long-term manner.
