Description

Technical Field

[0001] This invention relates to the field of sprinkler irrigation equipment technology, and in particular to a smart agriculture underground sprinkler irrigation system. Background Technology

[0002] Buried sprinkler irrigation equipment is an agricultural and garden irrigation system that is concealed and installed underground. Its core components (sprinklers, pipes, valves, etc.) are buried below the ground surface. Only the sprinkler heads pop out of the ground when irrigating and retract after the irrigation is finished. When not in use, the sprinkler heads are hidden underground and do not affect ground activities. At the same time, it has a highly efficient water-saving function.

[0003] Existing underground sprinkler irrigation equipment mostly consists of a main pipe and several sprinkler heads connected by a tie pipe. In actual use, this type of sprinkler irrigation equipment has several drawbacks. Firstly, traditional sprinkler heads mostly use a filter structure for individual filtration, which requires frequent cleaning and has high manual maintenance costs. Secondly, the clogging of the sprinkler heads is often only discovered after irrigation abnormalities, by which time the growth efficiency of crops has already been affected, resulting in shortcomings in its use. Summary of the Invention

[0004] This invention discloses a smart agriculture underground sprinkler irrigation device, which aims to solve the technical problem that existing underground sprinkler irrigation devices have shortcomings in filtration function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart agricultural underground sprinkler irrigation device includes a water pipe, and a connecting device is provided at the end of the water pipe. The connecting device includes a connecting member that is connected through to the end of the water pipe. One end of the connecting member has a water inlet end, the other end of the connecting member has a sewage outlet end, a flow stabilizing end is provided in the middle of the connecting member, and a water outlet end is provided through the end of the flow stabilizing end and is connected through to the water pipe. Several evenly distributed sprinklers are connected to the outside of the water pipe. The connecting device is equipped with a filtration mechanism for filtering water. The filtration mechanism includes a deflecting component that is slidably installed below the flow stabilizing end. The top of the deflecting component has a through port, and a filter screen is fixedly connected to the side of the deflecting component. The filter screen is distributed towards the water inlet end. The bottom of the connecting device is provided with a drive mechanism to adjust the filtering mechanism; The filtration mechanism, in conjunction with the drive mechanism, filters the water introduced into the water pipe by the connecting device.

[0006] An additional connecting device is installed at the end of the water pipe. A filter mechanism is installed inside the connecting device to filter the clean water entering the water pipe and the sprinkler, preventing small impurities such as mud and algae from clogging the sprinkler. At the same time, the filter mechanism, which intercepts dirt, gradually increases the water pressure inside the connecting device until the pressure reaches the preset value of the drive mechanism. At this time, the drive mechanism runs and performs self-cleaning of the filter mechanism, carrying the dirt inside the connecting device out of the equipment. This replaces manual cleaning and greatly improves the efficiency of traditional equipment operation and the convenience of use.

[0007] In a preferred embodiment, the filtration mechanism further includes a piston rod fixedly connected to the bottom of the deflecting member, the piston rod slidingly penetrating into the interior of the drive mechanism, and a scraper plate fixedly installed above the inner wall of the flow stabilizing end, the scraper plate making scraping contact with the filter screen.

[0008] By incorporating a deflector component inside the connecting component, and installing a filter screen structure on its inner side, the clean water flowing inside the connecting component is filtered through the filter screen. As more dirt accumulates on the filter screen surface, the water pressure at the inlet increases to the preset value of the drive mechanism. The drive mechanism then uses a piston rod to drive the deflector component to move vertically upwards, causing the filter screen to scrape off the dirt adhering to the filter screen surface. The dirt is then carried away from the drain end by the water pressure, thus replacing manual cleaning and significantly improving the operational efficiency and ease of use of traditional equipment.

[0009] In a preferred embodiment, the drive mechanism includes a diversion end extending below the water inlet end. The bottom of the diversion end is connected to a diversion pipe via a pressure valve. The piston rod is distributed inside the diversion pipe. A collar is fixedly fitted in the middle of the diversion pipe. A pressure relief sleeve is slidably distributed on the side of the collar. A pressure relief port is provided extending through the outer side of the diversion pipe. The pressure relief sleeve covers the inner side of the pressure relief port.

[0010] By additionally installing a pressure valve-controlled diversion pipe structure at the bottom of the connecting component, when a large amount of dirt accumulates on the filter screen surface, and the water pressure at the inlet increases to the preset value of the drive mechanism, the pressure valve is activated. This causes the accumulated water at the inlet of the connecting component to enter the interior of the diversion pipe through the pressure valve and push the piston rod, ensuring the proper operation of the filtration mechanism. As the water pressure at the inlet recovers, the piston rod, no longer limited by water pressure, resets and moves. Simultaneously, it pushes the pressure relief sleeve and pressure relief port to misalign, draining the accumulated water inside the diversion pipe, thereby maintaining the pressure inside the diversion pipe and ensuring the proper operation of the equipment.

[0011] In a preferred embodiment, the sprinkler includes a horizontal pipe that extends through the outside of the water pipe, and a spray bar that extends through the other end of the horizontal pipe. The spray bar is embedded in the soil, and a nozzle is provided at the top of the spray bar. The nozzles are distributed above the ground surface.

[0012] By additionally installing several spray bars and nozzles connected by a continuous pipe on the outside of the water pipe, filtered clean water is brought into the spray bars and nozzles and sprayed out to irrigate the crops on the ground, ensuring the proper operation of the sprinkler irrigation equipment.

[0013] In a preferred embodiment, a mounting bracket is fixed inside the flow stabilizing end, the mounting bracket is attached to the side of the reversing component, and a magnetic suction element is fixedly installed in the middle of the mounting bracket. The magnetic suction element is magnetically connected to the filter screen, causing the filter screen to be recessed inward toward the mounting bracket.

[0014] By adding a mounting bracket structure to the side of the reversing component, the filter screen in its initial position is concave due to the magnetic attraction in the middle of the mounting bracket. This allows the concave filter screen to hold a larger area of ​​dirt. When the reversing component moves the filter screen vertically, the elastically reset filter screen can flatten and contact the shovel plate, thus performing normal impurity removal and improving the functionality of the equipment.

[0015] As can be seen from the above, the smart agricultural underground sprinkler irrigation equipment provided by the present invention has the following technical effects.

[0016] Firstly, by adding a connecting device to the end of the water pipe on the basis of traditional buried sprinkler irrigation equipment, a deflector is installed inside the connecting member. A filter structure is installed on the inner side of the deflector. The filter filters the clean water flowing inside the connecting member. As more dirt accumulates on the surface of the filter, the water pressure at the inlet increases to the preset value of the drive mechanism. The drive mechanism uses the piston rod to drive the deflector to move vertically upward, causing the filter to scrape off the dirt adhering to the filter surface and use water pressure to carry it away from the drain end. This replaces manual cleaning and greatly improves the efficiency of traditional equipment operation and the convenience of use.

[0017] Secondly, by additionally setting a pressure valve-controlled diversion pipe structure at the bottom of the connecting part, when the water pressure at the inlet increases to the preset value of the drive mechanism, the pressure valve is activated, causing the accumulated water at the inlet inside the connecting part to enter the interior of the diversion pipe through the pressure valve and push the piston rod, ensuring the normal operation of the filtration mechanism. As the water pressure at the inlet recovers, the piston rod, which is no longer limited by water pressure, moves to its reset position. While moving, it pushes the pressure relief sleeve and pressure relief port to misalign, draining the accumulated water inside the diversion pipe, thereby maintaining the pressure inside the diversion pipe and ensuring the integrity of the equipment's operation.

[0018] Thirdly, by adding a mounting bracket structure to the side of the reversing component on the basis of the filtration mechanism, the magnetic suction component in the middle of the mounting bracket causes the filter screen in the initial position to be in a concave state. This allows the concave filter screen to bear a larger area of ​​dirt. When the reversing component moves the filter screen vertically, the elastically reset filter screen can flatten and contact the shovel plate, thereby performing normal impurity removal function and improving the functionality and working efficiency of the equipment.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] The smart agriculture underground sprinkler irrigation equipment disclosed in this invention is mainly used in scenarios of intelligent irrigation of crops.

[0032] Reference Figures 1 to 10 A smart agricultural underground sprinkler irrigation device includes a water pipe 1, a connecting device 2 at the end of the water pipe 1, the connecting device 2 including a connecting member 201 that is connected to the end of the water pipe 1, one end of the connecting member 201 having a water inlet 202, the other end of the connecting member 201 having a sewage outlet 203, a flow stabilizing end 204 in the middle of the connecting member 201, and a water outlet 205 that is connected to the water pipe 1 through the water outlet 205; Several evenly distributed sprinklers 3 are connected to the outside of the water pipe 1; The connecting device 2 is equipped with a filter mechanism 4 for filtering water quality. The filter mechanism 4 includes a deflecting component 401 that is slidably installed below the flow stabilizing end 204. The top of the deflecting component 401 is provided with a port 402. A filter screen 403 is fixedly connected to the side of the deflecting component 401. The filter screen 403 faces the distribution end of the water inlet end 202. The bottom of the connecting device 2 is provided with a drive mechanism 5 for adjusting the filter mechanism 4; The water quality inside the water pipe 1 introduced by the connecting device 2 is filtered by the filter mechanism 4 in conjunction with the drive mechanism 5.

[0033] In this embodiment: the worker connects the inlet end 202 of the connector 201 to the main water gate, and simultaneously connects the outlet end 205 to the water pipe 1. Several sprinklers 3 are then evenly connected to the outside of the water pipe 1. The water pipe 1 and sprinklers 3 are then buried underground. When the crops on the surface need irrigation, the worker activates the main water gate, causing clean water to enter through the inlet end 202 of the connector 201, reach the inside of the flow stabilizing end 204, and enter the inside of the water pipe 1 from the outlet end 205. The water is then evenly sprayed from the inside of the sprinklers 3 onto the surface of the crops. While the water enters the steady flow end 204, it is filtered and impurities removed by the filter mechanism 4 to prevent mud and algae in the water from clogging the outlet of the sprinkler 3. As more and more impurities accumulate on the surface of the filter mechanism 4, the water pressure inside the inlet end 202 will gradually increase until the water pressure reaches the threshold of the drive mechanism 5. At this time, the drive mechanism 5 starts and drives the filter mechanism 4 to run, cleaning off the dirt adhering to the surface of the filter mechanism 4 and using water pressure to carry it out from the inside of the drain end 203 and the connecting part 201. This process is repeated, and the equipment repeats the above steps to perform water filtration and self-cleaning operation.

[0034] The end of the sewage discharge end 203 is equipped with a screen cover 2031 to prevent external debris from entering the interior of the sewage discharge end 203.

[0035] Reference Figures 5 to 8 In a preferred embodiment, the filtration mechanism 4 further includes a piston rod 404 fixedly connected to the bottom of the deflection member 401. The piston rod 404 slides through the interior of the drive mechanism 5. A scraper plate 405 is fixedly installed above the inner wall of the flow stabilizing end 204. The scraper plate 405 and the filter screen 403 are in scraping contact.

[0036] Workers activate the main water gate, causing clean water to enter through the inlet 202 of the connecting component 201 and reach the interior of the flow stabilizing end 204. The clean water inside the flow stabilizing end 204 enters through the filter screen 403 at the end of the deflecting component 401 and flows upward from the port 402 at the top of the deflecting component 401. It then enters the interior of the water pipe 1 from the outlet 205 and is evenly sprayed onto the surface of the crops from inside the sprinkler 3. As the clean water enters the flow stabilizing end 204, it is filtered and impurities are removed by the filter screen 403, intercepting dirt such as mud and algae. As more and more impurities accumulate on the surface of the filter screen 403, the water pressure inside the inlet end 202 will gradually increase until the water pressure reaches the threshold of the drive mechanism 5. At this time, the drive mechanism 5 starts and pushes the piston rod 404, causing the piston rod 404 to drive the reversing component 401 and the filter screen 403 to move vertically upward. The moving filter screen 403 will squeeze and contact the shovel plate 405 fixed on the upper part of the inner wall of the flow stabilizing end 204, thereby cleaning off the dirt adhering to the surface of the filter screen 403 and using water pressure to carry the dirt out from the drain end 203.

[0037] The flow stabilizer 204 has a mounting bracket 406 fixed inside. The mounting bracket 406 is attached to the side of the direction change component 401. A magnetic suction component 407 is fixedly installed in the middle of the mounting bracket 406. The magnetic suction component 407 is magnetically connected to the filter screen 403, causing the filter screen 403 to be concave in the direction of the mounting bracket 406. When in the initial position, the filter screen 403 will be attracted by the magnetic suction component 407, thus creating a concave shape. At this time, the filtration range of the filter screen 403 increases. When the filter screen 403 moves vertically upward and releases the attraction relationship with the magnetic suction component 407, the filter screen 403 will elastically reset, become flat, and be scraped by the scraper plate 405.

[0038] Reference Figures 1 to 2 , Figures 4 to 5 , Figures 8 to 10 In a preferred embodiment, the drive mechanism 5 includes a diversion end 501 that extends through and is located below the water inlet end 202. The bottom of the diversion end 501 is connected to a diversion pipe 502 through a pressure valve 503. A piston rod 404 is distributed inside the diversion pipe 502. A collar 504 is sleeved and fixed in the middle of the diversion pipe 502. A pressure relief sleeve 505 is slidably distributed on the side of the collar 504. A pressure relief port 506 extends through the outside of the diversion pipe 502. The pressure relief sleeve 505 covers the inside of the pressure relief port 506.

[0039] As more and more impurities accumulate on the surface of the filter screen 403, the water pressure inside the inlet end 202 gradually increases until it reaches the threshold of the pressure valve 503. At this point, the pressure valve 503 starts to activate, causing the high-pressure clean water inside the inlet end 202 to enter the interior of the diversion pipe 502 through the diversion end 501. This pushes the piston rod 404, causing the piston rod 404 to drive the deflector component 401 and the filter screen 403 to move vertically upwards. The moving filter screen 403 will come into contact with the scraper plate 405 fixed on the upper part of the inner wall of the flow stabilizing end 204, thereby cleaning off the dirt adhering to the surface of the filter screen 403 and using water pressure to carry the dirt out from the drain end 203. As the filter screen 403 and the deflector 401 move vertically upwards, a passage is formed between the inlet end 202 and the outlet end 203. At this time, the water pressure at the inlet end 202 returns to normal, and the pressure valve 503 closes. The piston rod 404 located inside the diversion pipe 502 loses the push of water pressure. At this time, the piston rod 404 moves to its reset position. At the same time, the clean water accumulated inside the diversion pipe 502 pushes the pressure relief sleeve 505, causing the pressure relief sleeve 505 to move horizontally, exposing the pressure relief port 506. At this time, the clean water inside the diversion pipe 502 will flow towards the pressure relief port 506 with the push of the piston rod 404 and flow out from the diversion pipe 502.

[0040] A spring 408 is fixedly installed in the middle of the piston rod 404. The spring 408 is distributed inside the diversion pipe 502. When the water pressure at the inlet 202 returns to normal and the pressure valve 503 closes, the piston rod 404 inside the diversion pipe 502 loses the water pressure push. At this time, the piston rod 404 will be pushed by the spring 408 and thus move back to its original position. An elastic element 507 is fixedly connected between the collar 504 and the pressure relief sleeve 505. As the piston rod 404 moves back to its original position, the spring 408 pushes the piston rod 404 back to its original position, thus moving back to its original position. The water accumulated inside 502 is pushed and simultaneously pushes the pressure relief sleeve 505, causing the pressure relief sleeve 505 to move horizontally overcoming the resistance of the elastic element 507, exposing the pressure relief port 506. At this time, the water inside the diversion pipe 502 will flow towards the pressure relief port 506 as pushed by the piston rod 404, and flow out from the diversion pipe 502 until the water pressure inside the diversion pipe 502 stabilizes. At this time, the elastic element 507, which has undergone reset deformation, will push the pressure relief sleeve 505, causing the pressure relief sleeve 505 to reset and move.

[0041] Furthermore, the inner wall of the pressure relief sleeve 505 is provided with a constriction portion 5051. When the clean water inside the diversion pipe 502 flows toward the pressure relief sleeve 505 as the piston rod 404 pushes it, the constriction portion 5051 inside the pressure relief sleeve 505 will have a gathering effect on the clean water, thereby increasing the pushing force on the pressure relief sleeve 505. Moreover, the pressure relief port 506 is distributed at the end of the pressure relief sleeve 505 away from the pressure valve 503, ensuring that the pressure relief port 506 can be exposed with a small movement of the pressure relief sleeve 505.

[0042] Reference Figures 1 to 3 In a preferred embodiment, the sprinkler 3 includes a horizontal pipe 301 that is connected to the outside of the water pipe 1. The other end of the horizontal pipe 301 is connected to a spray bar 302, which is embedded in the soil. A nozzle 303 is provided on the top of the spray bar 302, and the nozzles 303 are distributed above the ground surface.

[0043] The clean water entering the water pipe 1 will enter the spray bar 302 through the swing pipe 301, and be sprayed out through the nozzle 303 at the top of the spray bar 302 to irrigate the crops on the ground.

[0044] Working principle: In use, the worker connects the inlet end 202 of the connecting piece 201 to the main water gate, and simultaneously connects the outlet end 205 to the water pipe 1. Several sprinklers 3 are then evenly connected to the outside of the water pipe 1. The water pipe 1 and sprinklers 3 are then buried underground. When the crops on the surface need irrigation, the worker activates the main water gate, causing clean water to enter through the inlet end 202 of the connecting piece 201 and reach the interior of the flow stabilizing end 204. The clean water inside the flow stabilizing end 204 enters through the filter screen 403 at the end of the deflector component 401, and... The water flows upward from the port 402 at the top of the deflector 401, enters the water pipe 1 from the outlet 205, and is then evenly sprayed onto the surface of the crops from inside the sprinkler 3. As the clean water enters the flow stabilizer 204, it is filtered by the filter screen 403, which removes impurities such as mud and algae. As more and more impurities accumulate on the surface of the filter screen 403, the water pressure inside the inlet 202 gradually increases until it reaches the threshold of the pressure valve 503. At this point, the pressure valve 503 activates, causing the high-pressure clean water inside the inlet 202 to flow through... The water enters the interior of the diversion pipe 502 through the diversion end 501 and pushes the piston rod 404, causing the piston rod 404 to drive the reversing component 401 and the filter screen 403 to move vertically upward. The moving filter screen 403 will squeeze and contact the scraper plate 405 fixed on the upper part of the inner wall of the flow stabilizing end 204, thereby cleaning off the dirt adhering to the surface of the filter screen 403 and using water pressure to carry the dirt out from the drain end 203. As the filter screen 403 and the reversing component 401 move vertically upward, a passage is formed between the inlet end 202 and the drain end 203. At this time, at the inlet end 202... When the water pressure returns to normal and the pressure valve 503 closes, the piston rod 404 inside the diversion pipe 502 loses the water pressure push. At this time, the piston rod 404 moves to its reset position. While moving, the clean water accumulated inside the diversion pipe 502 pushes the pressure relief sleeve 505, causing the pressure relief sleeve 505 to move horizontally, exposing the pressure relief port 506. At this time, the clean water inside the diversion pipe 502 will flow towards the pressure relief port 506 with the push of the piston rod 404 and flow out from the diversion pipe 502. This process is repeated, and the equipment repeats the above steps to perform water filtration and self-cleaning operation.
