Description

Technical Field

[0001] This utility model relates to the field of drip irrigation device technology, specifically to a drip irrigation device with adjustable flow rate. Background Technology

[0002] Adjustable flow drip irrigation devices are the core component of modern agricultural drip irrigation systems. The water flow can be adjusted through manual valves, electronic controllers and other components. It can accurately deliver water or water-fertilizer mixture to the roots of crops, adapting to the different water requirements of different crops and growth stages. It reduces water waste and avoids over-irrigation or under-irrigation, helping to improve irrigation efficiency and crop yield. It is widely used in greenhouses, open fields and other planting scenarios.

[0003] Utility model patent CN219555857U discloses a drip irrigation device with adjustable flow rate, including a cylinder, a cover, a lifting plate, and a water outlet pipe. The cylinder contains a partition with multiple through holes. The cover is positioned over the top of the cylinder. The upper surface of the lifting plate has a lifting shaft that can move up and down relative to the cover. The lower surface of the lifting plate has protrusions, the number of which is less than or equal to the number of through holes. Each protrusion corresponds to one through hole. When the lifting shaft descends, the protrusions can extend into the through holes to change the flow area of ​​the through holes. The water outlet pipe is located at the bottom of the cylinder and has multiple drip heads along its length. This application modifies the actual flow area of ​​the through holes, thus changing the flow rate from the drip heads and expanding the applicability of the drip irrigation device.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Existing drip irrigation devices typically have flow regulation functions, but in actual use, when the nozzles start spraying water, the silt and other fine particles carried in the water flow tend to gradually adhere to and deposit inside the outlet holes. Over time, the accumulation of these impurities will cause the flow cross-section to continuously shrink, and may even cause the nozzles to become completely blocked. This not only directly affects the uniformity and stability of the drip irrigation flow, but also increases the maintenance and cleaning burden of the equipment, thereby reducing the overall effectiveness of the drip irrigation device. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a drip irrigation device with adjustable flow rate, which can effectively solve the problems of easy clogging of the water outlet of the drip irrigation device, affecting the stability of the flow rate and increasing the maintenance burden.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] See attached document Figure 1-4 An adjustable flow drip irrigation device includes: a drip irrigation device body 1 and a drip irrigation head 2. The water outlet of the drip irrigation device body 1 is connected to the drip irrigation head 2. A movable cleaning component 3 is provided inside the drip irrigation head 2. The movable cleaning component 3 includes a movable ring 31. A collection groove 32 is provided on the top of the movable ring 31. A sealing ring 33 is movably connected to the bottom of the collection groove 32. A connecting ring 34 is fixedly connected to the bottom of the movable ring 31 through a connecting rod. A scraper ring 35 is fixedly connected to the bottom of the connecting ring 34. The scraper ring 35 is slidably connected to the water outlet of the drip irrigation head 2. A support ring 36 is fixedly connected to the bottom of the movable ring 31 through a spring. The support ring 36 is fixedly connected to the inside of the drip irrigation head 2.

[0029] The top of the moving ring 31 is connected to an impact cleaning component 4. The impact cleaning component 4 includes a fixed post 41, and the end of the fixed post 41 away from the moving ring 31 is fixedly connected to the inside of the drip head 2. A spiral groove 42 is opened on the top of the fixed post 41. A movable ring 43 is slidably connected to the end of the spiral groove 42 near the moving ring 31, and the movable ring 43 is fixedly connected to the moving ring 31. When the drip irrigation device body 1 delivers water to the drip head 2, the water flow will act on the spiral groove 42 of the impact cleaning component 4 and slide along the spiral groove 42, thereby generating an impact force that acts on the top of the collection tank 32. As water continuously accumulates in the collection tank 32, the sealing ring 33 will prevent the water from leaking downwards. When the gravity of the water flow reaches a certain level... When the water level drops to a certain point, the moving ring 31 will move downwards, separating from the sealing ring 33, allowing the water in the collection tank 32 to flow downwards. Subsequently, the moving ring 31, via the connecting rod, will drive the connecting ring 34 and the scraper ring 35 to move synchronously. The scraper ring 35 will slide on the inner wall of the drip head 2's outlet, scraping away impurities adhering to the inner wall. When the water level above the moving ring 31 drops to a certain level, the spring at the top of the support ring 36 will exert a reset force on the moving ring 31, returning it to its initial position. This cycle repeats, achieving automatic cleaning of the drip head 2's outlet, effectively preventing clogging of the outlet, ensuring the uniformity and stability of the drip flow, and reducing the maintenance burden of the equipment.

[0030] The bottom of the collection tank 32 is provided with a drain hole 5; the drain hole 5 allows water to flow through the collection tank 32 and be discharged, ensuring the normal water storage and drainage functions of the collection tank 32; a magnetic block 6 is fixedly connected to the top of the support ring 36, and a connecting block 7 is magnetically connected to the top of the magnetic block 6, and the connecting block 7 is fixedly connected to the bottom of the moving ring 31; the magnetic block 6 at the top of the support ring 36 and the connecting block 7 at the bottom of the moving ring 31 form a magnetic connection, which not only slows down the speed at which the spring pushes the moving ring 31 to reset, preventing the water in the collection tank 32 from not being effectively discharged due to the support ring 36 moving too fast, but also makes the moving ring 31 more stable when resetting, avoiding excessive impact during the reset process that affects the sealing ring 33 and the bottom of the collection tank 32, ensuring the normal functioning of the water storage function of the collection tank 32; several sets of elastic protrusions 8 are fixedly connected to the outside of the scraper ring 35, and a guide ring 9 is fixedly connected to the bottom of the connecting ring 34; the elastic protrusions 8 on the outside of the scraper ring 35 can use their own elasticity to tightly fit the drip head 2. Even if there are minor depressions or unevenness on the inner wall of the water outlet, the elastic protrusion 8 can still fit against it, thereby more thoroughly scraping away the impurities attached to the inner wall and improving the cleaning effect. The guide ring 9 at the bottom of the connecting ring 34 can guide the water flow from below the connecting ring 34, so that the water flow moves along the guide ring 9 to the outside of the scraper ring 35, so that the water flow directly impacts the inner wall of the water outlet, effectively rinsing away the impurities in conjunction with the scraper ring 35 and the elastic protrusion 8. The inner side of the support ring 36 is fixedly connected to the partition ring 10, and the top of the partition ring 10 is slidably connected to the moving ring 31. The partition ring 10 on the inner side of the support ring 36 can prevent the water flow from directly contacting the spring, avoiding impurities in the water flow from adhering to the spring surface and causing damage to the spring elasticity or jamming. It can also guide the water flow to flow downward quickly, avoiding water flow from stagnating and adhering in the support ring 36. At the same time, it can also separate the spring installation area from the water flow channel, ensuring that the spring works in a relatively dry and stable environment, ensuring that its reset function of the moving ring 31 is always stable and reliable.

[0031] The top of the sealing ring 33 is inclined, and the top of the sealing ring 33 is fixedly connected to the bottom of the fixing post 41 by a fixing rod. The inclined top of the sealing ring 33 can guide the water flowing into the collection tank 32 to quickly converge to the bottom of the collection tank 32 along the inclined surface. This not only speeds up the discharge efficiency of the water in the collection tank 32, but also reduces the accumulation and retention of impurities on the top of the sealing ring 33. At the same time, the inclined surface can also help the water flow to form a certain downward force. Combined with the impact force generated by the water flow in the spiral groove 42, it can more thoroughly flush away the impurities remaining in the collection tank 32, improve the cleaning effect of impurities, and prevent impurities from getting stuck at the contact position between the sealing ring 33 and the collection tank 32, affecting the sealing performance. An elastic ring 11 is embedded and fixedly connected to the outer side of the sealing ring 33, and an elastic cleaning block 12 is fixedly connected to the outer side of the elastic ring 11. The elastic ring 11 on the outer side of the sealing ring 33 can use its own elasticity to make the elastic cleaning block 12 fit tightly against the inner wall of the collection tank 32. When the moving ring 31 moves up and down, the inner wall of the collection tank 32 will slide relative to the elastic cleaning block 12. The elastic cleaning block 12 can scrape off the impurities attached to the inner wall of the collection tank 32, avoiding the accumulation of impurities on the inner wall of the collection tank 32, which would reduce the water storage capacity of the collection tank 32. At the same time, it prevents impurities from being trapped between the sealing ring 33 and the bottom of the collection tank 32, affecting the sealing effect, and ensuring that the collection tank 32 can normally realize the circulation of water storage and drainage.

[0032] Working principle: When using this adjustable flow drip irrigation device, the drip irrigation device body 1 first delivers water to the drip irrigation head 2. After the water enters the drip irrigation head 2, it will first contact the fixed column 41. Since the fixed column 41 has a spiral groove 42 at the top and a movable ring 43 fixed to the moving ring 31 is slidably connected at the bottom of the groove, the water will flow along the spiral groove 42 and generate an impact force. This impact force directly acts on the collection tank 32 at the top of the moving ring 31. As the water continues to enter the collection tank 32, the sealing ring 33 at the bottom of the collection tank 32 will temporarily block the water from leaking downward, so that the water in the collection tank 32 gradually accumulates. When the gravity of the water reaches a certain level, it will overcome the magnetic attraction between the magnetic block 6 at the top of the support ring 36 and the connecting block 7 at the bottom of the moving ring 31 as well as the initial elastic force of the spring, and push the moving ring 31 to move downward as a whole. At this time, the moving ring 31 separates from the sealing ring 33, and the water in the collection tank 32 flows downward through the drain hole 5 at the bottom.

[0033] As the moving ring 31 moves downward, it drives the connecting ring 34 to move downward synchronously via the connecting rod at the bottom. The scraper ring 35 fixed at the bottom of the connecting ring 34 slides against the inner wall of the water outlet end of the drip head 2. Since several sets of elastic protrusions 8 are fixed on the outer side of the scraper ring 35, the elastic protrusions 8 can use their own elasticity to tightly fit against the inner wall of the water outlet end. Even if there are small depressions or unevenness in the inner wall, they can still make full contact, thereby more thoroughly scraping away the mud, sand and fine particles attached to the inner wall. At the same time, the guide ring 9 at the bottom of the connecting ring 34 guides the water flow from below the connecting ring 34, so that the water flow is along the guide ring. 9 moves to the outside of the scraper ring 35 and directly impacts the inner wall of the water outlet. In conjunction with the scraping action of the scraper ring 35 and the elastic protrusion 8, the scraped impurities are thoroughly washed away to prevent them from re-attaching and depositing, thus affecting the smoothness of the water flow. During this process, the partition ring 10 fixed inside the support ring 36 can prevent the water flow from directly contacting the spring between the support ring 36 and the moving ring 31, thus preventing impurities in the water flow from adhering to the surface of the spring and causing damage to the spring's elasticity or jamming. At the same time, it guides the water flow to flow downward quickly, reducing the water flow's stagnation and adhesion at the support ring 36, and ensuring that the spring always works in a relatively dry and stable environment.

[0034] When the water level above the support ring 36 drops to a certain level, the downward pressure of the water flow on the moving ring 31 gradually weakens. At this time, the spring will release elastic potential energy to generate a reset force, pushing the moving ring 31 upward to return to its initial position. During the reset process, the magnetic block 6 at the top of the support ring 36 is magnetically connected to the connecting block 7 at the bottom of the moving ring 31. This magnetic connection can effectively slow down the reset speed of the moving ring 31, prevent the moving ring 31 from resetting too quickly and causing the residual water in the collection tank 32 to not be effectively discharged. At the same time, it makes the reset process of the moving ring 31 more stable, avoids the impact of the reset on the sealing ring 33 and the bottom of the collection tank 32, and ensures that the collection tank 32 can normally carry out the next round of water storage.

[0035] When the moving ring 31 returns to its initial position, the sealing ring 33 will once again fit tightly against the bottom of the collecting tank 32, preventing water leakage. Then, the collecting tank 32 will begin a new round of water accumulation. Once the water volume reaches the threshold, it will push the moving ring 31 down to clean. This cycle repeats continuously. Through continuous automatic cleaning, it effectively prevents the flow cross-section from shrinking or becoming blocked due to the accumulation of impurities at the water outlet of the drip irrigation head 2, ensuring the uniformity and stability of the drip irrigation flow. At the same time, it greatly reduces the maintenance and cleaning burden of the equipment, ensuring that the drip irrigation device can operate stably for a long time to meet the irrigation needs of different crops.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
