Detailed Implementation

[0029] 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.

[0030] Please see Figures 1-3 In this embodiment of the utility model, a capillary irrigation device for water resource regulation includes a water storage tank 1 fixedly installed on a bracket 2. The water storage tank 1 is used to store and regulate water sources (rainwater, reclaimed water, etc.). A water outlet pipe 3 is fixedly installed through the outer wall of the water storage tank 1. A valve 4 is installed on the water outlet pipe 3. A stainless steel filter 5 is threadedly connected to one end of the water outlet pipe 3 inside the water storage tank 1. The stainless steel filter 5 is selected with a precision of 50-100μm, which can intercept small impurities and ensure the smooth flow of the capillary water guiding structure. A diversion pipe 6 is connected to the other end of the water outlet pipe 3 outside the water storage tank 1. Multiple irrigation hoses 7 are connected to the diversion pipe 6 through a three-way connector. A plug 18 is installed at the end of the irrigation hose 7 away from the diversion pipe 6. The outer wall of the irrigation hose 7 is fitted with a plug 18. The system is equipped with several drip irrigation mechanisms, each including an externally threaded pipe 11. A through-hole 9 is provided on the outer wall of the drip irrigation hose 7 for the externally threaded pipe 11 to pass through. The externally threaded pipe 11 is located within the corresponding through-hole 9, and a tapered pipe 10 is fixedly installed at one end of the externally threaded pipe 11 inside the drip irrigation hose 7. The maximum outer diameter of the tapered pipe 10 is larger than the diameter of the through-hole 9. A nut 16 is fitted onto the outer wall of the externally threaded pipe 11 outside the drip irrigation hose 7. A porous ceramic rod 12 is fixedly installed inside the externally threaded pipe 11 using waterproof sealant. A hydrophilic polyester fiber felt tube 8 is provided inside the drip irrigation hose 7. The hydrophilic polyester fiber felt tube 8 is made of modified hydrophilic polyester fiber with a porosity of 30%-40%, strong capillary water conduction capacity, and is resistant to aging and degradation.

[0031] It is worth noting that the drip irrigation hose 7 is made of high-density polyethylene (HDPE) and ethylene-vinyl acetate copolymer (EVA) composite material, with HDPE accounting for 70%-80% to ensure the pipe's pressure resistance and aging resistance, and EVA accounting for 20%-30% to improve the pipe's flexibility and elasticity, preventing cracking caused by soil compression or low temperature (-10℃ to -5℃) after burial; 0.5%-1% of hydrophilic modifier (such as polyethylene glycol derivative) is added to the inner wall of the pipe to enhance the fit between the inner wall and the hydrophilic polyester fiber felt pipe and reduce water stagnation in the pipe.

[0032] The present invention adopts the above-mentioned solution. During installation, after digging a trench on the ground, the drip irrigation hose 7 connected to the diversion pipe 6 is laid in the trench. According to the distribution of the planted crops or trees, a punch is used to make perforations 9 at corresponding positions on the surface of the drip irrigation hose 7. Then, the tapered tube 10 at the end of the external threaded tube 11 is inserted into the drip irrigation hose 7 through the perforation 9. Then, the nut 16 is tightened on the external threaded tube 11 to fix the porous ceramic rod 12 on the drip irrigation hose 7. The outer surface of the porous ceramic rod 12 located inside the drip irrigation hose 7 will be in contact with the hydrophilic polyester fiber felt tube 8. Finally, the trench is backfilled to complete the installation.

[0033] When in use, open the valve 4 on the outlet pipe 3, and the water in the water storage tank 1 will flow into each drip irrigation hose 7 through the diversion pipe 6 and be absorbed by the hydrophilic polyester fiber felt tube 8. The porous ceramic rod 12 will absorb the water in the hydrophilic polyester fiber felt tube 8 under capillary action and continuously discharge it to the surrounding soil to achieve targeted drip irrigation.

[0034] Specific combination Figure 2 In one embodiment of this utility model, the bottom end of the porous ceramic rod 12 is conical and penetrates into the middle of the hydrophilic polyester fiber felt tube 8, so that the contact between the porous ceramic rod 12 and the hydrophilic polyester fiber felt tube 8 is closer, thereby ensuring the capillary water conduction effect and preventing the porous ceramic rod 12 from not discharging water due to water flow interruption.

[0035] Specific combination Figure 1-3 In one embodiment of this utility model, a hexagonal pressure block 13 is fitted on the outer wall of the externally threaded pipe 11. The hexagonal pressure block 13 is located between the nut 16 and the irrigation hose 7. The top of the hexagonal pressure block 13 is a flat surface that fits with the nut 16, and the bottom of the hexagonal pressure block 13 is an arc surface that matches the outer diameter of the irrigation hose 7. The top of the tapered pipe 10 is an arc surface that matches the inner diameter of the irrigation hose 7, so that the hexagonal pressure block 13 and the tapered pipe 10 can better fit the inner and outer walls of the irrigation hose 7. After tightening the nut 16 on the externally threaded pipe 11, the pipe wall of the irrigation hose 7 outside the perforation 9 can be clamped between the hexagonal pressure block 13 and the tapered pipe 7 to prevent water leakage at the perforation 9, so that the water in the irrigation hose 7 can only seep out through the porous ceramic rod 12.

[0036] Specific combination Figure 3 In one embodiment of this utility model, a groove 15 is provided on the outer peripheral wall of the externally threaded tube 11, and a slider 14 is fixedly provided on the inner wall of the hexagonal pressure block 13. The slider 14 is located in the corresponding groove 15 so that the hexagonal pressure block 13 cannot rotate on the externally threaded tube 11. Therefore, during the process of tightening the nut 16 on the externally threaded tube 11, one wrench can be used in conjunction with the hexagonal pressure block 13, and another wrench can be used to rotate the nut 16, thereby preventing the tapered tube 10, the externally threaded tube 11, etc. from rotating together with the nut 16 during the tightening of the nut 16, and ensuring that the drip irrigation hose 7 and the internal hydrophilic polyester fiber felt tube 8 are not damaged during the installation process.

[0037] Specific combination Figure 1 and Figure 2 In one embodiment of this utility model, a stainless steel mesh cover 17 is fixedly connected to the top of the nut 16, and the top of the porous ceramic rod 12 is located inside the stainless steel mesh cover 17. The stainless steel mesh cover 17 can physically isolate the plant roots without affecting the water seepage of the porous ceramic rod 12 into the soil, thus preventing the water outflow of the porous ceramic rod 12 from being affected by the roots invading into the porous ceramic rod 12.

[0038] In addition, the outer surface of the stainless steel mesh cover 17 is provided with a copper plating layer. The copper plating layer will slowly release copper ions in the moist soil to inhibit the activity of meristematic tissue of the surrounding root system, so as to stop the root tip growth and thus further improve the protection against root invasion.

[0039] specific collection Figure 1 In one embodiment of this utility model, the bottom of the water storage tank 1 is conical, which can settle the water pumped into the water storage tank 1 and cause impurities to be deposited in the bottom of the cone. A drain pipe 25 is installed at the bottom of the water storage tank 1, and a plug 26 is threadedly installed at the bottom of the drain pipe 25. By periodically opening the plug 26, the impurities settled in the water storage tank 1 can be discharged, which facilitates the cleaning of the water storage tank 1. The stainless steel filter 5 is located above the conical bottom of the water storage tank 1, thereby keeping the stainless steel filter 5 away from the sediment and extending the cleaning cycle of the stainless steel filter 5.

[0040] Specific combination Figure 1 In one embodiment of this utility model, the water inlet of a water pump 19 is installed on the outside of the water storage tank 1 and is connected to a water source through a water pumping pipe 20. The water outlet of the water pump 19 is equipped with a water injection pipe 21 to facilitate the injection of water into the water storage tank 1 through the water pump 19. The outlet of the water injection pipe 21 faces and is close to the inner wall of the water storage tank 1, thereby avoiding the water injected into the water storage tank 1 from directly impacting the liquid surface, reducing the impact on the sediment in the cone bottom, and ensuring the stable operation of the stainless steel filter 5.

[0041] Specific combination Figure 1 In one embodiment of this utility model, a cover 22 is installed at the top opening of the water storage tank 1 to reduce debris entering the water storage tank 1 through the opening. A level transmitter 23 is installed on the cover 22. A control cabinet 24 is installed on the outer wall of the water storage tank 1. A controller is installed in the control cabinet 24, and the water pump 19 and the level transmitter 23 are electrically connected to the controller. Through the setting of the level transmitter 23, the liquid level in the water storage tank 1 can be monitored in real time. When the liquid level drops to a set value, the water pump 19 is started to replenish the water storage tank 1, and the water pump 19 is turned off after the liquid level reaches the preset height to avoid water overflow.

[0042] In addition, a solar cell system can be installed on the water storage tank 1 to use solar energy to power the water pump, level transmitter 23 and controller, etc., adapting to outdoor storage scenarios without external power supply and improving the versatility of the equipment.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
