Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation equipment technology, and in particular to a smart agricultural irrigation system based on the Internet of Things. Background Technology

[0002] In paddy field irrigation management, gates are key equipment for controlling water flow between upper and lower level fields. In the existing technology, a widely used paddy field gate structure is a bottom-up moving opening gate. Its basic working principle is: the valve plate is lifted from bottom to top through the through hole of the valve seat under the drive mechanism (such as screw lifting mechanism, electric push rod, etc.), so that the water flow enters the upper field from the lower channel or is discharged from the upper field to the lower field.

[0003] However, when these bottom-opening gates fail to close in time due to mechanical failure, power interruption, or operator negligence, the valve plate will remain open for an extended period. Because water from the upstream paddy field continuously flows through the gate to the downstream paddy field or drainage ditch after the valve plate is raised, without intervention, an entire upstream or higher-level paddy field can dry up completely overnight. This not only wastes a large amount of water resources but also severely impacts the normal growth of rice due to water shortage, potentially leading to large-scale yield reduction or crop failure, causing significant economic losses to agricultural production. Existing paddy field gate technologies, such as automatic water replenishment gates based on water level sensors and motor drives, primarily address the issue of automatic water replenishment, rather than preventing complete water loss due to gate malfunction or forgetting to close. While some self-operated gates can automatically shut off water through water pressure, their structure lacks specific safety protection against the "always open, forgotten to close" fault mode of bottom-opening gates. Therefore, a new gate solution is urgently needed that incorporates a reliable remedial structure on top of existing bottom-opening gates. Summary of the Invention

[0004] This invention discloses an Internet of Things-based smart agricultural irrigation system, which aims to solve the technical problem that existing bottom-up movable open paddy field gates and irrigation systems can cause complete loss of water from the upper paddy field when they cannot be closed due to mechanical failure or human negligence.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A smart agricultural irrigation system based on the Internet of Things includes a drain pipe, with a control component for controlling irrigation installed at the end of the drain pipe; a protective component for protecting against water leakage is provided inside the drain pipe and between the control component. The control component includes a back plate fixedly installed at the end of the drain pipe, and a gate is slidably installed on the side of the back plate, with the gate distributed on the outside of the drain pipe. The protective assembly includes a sealing sleeve fixedly installed inside the drain pipe. The sealing sleeve is fitted against the side wall of the back plate. A float is floating inside the sealing sleeve. A sealing plate is slidably installed inside the float. The sealing plate extends through the top of the float, the sealing sleeve, and the drain pipe. A pressing member is fixedly installed on the back of the gate. The pressing member and the sealing plate make pressing contact when the gate moves vertically.

[0006] By adding control and protection components along the outer side of the farmland drainage pipes to the existing agricultural irrigation system and equipment, the system first utilizes remote control in conjunction with a rack and pinion structure to move the gate, achieving intelligent control of irrigation. Simultaneously, while retaining the original bottom-up opening gate, a sealing plate structure driven by a float is added. During normal water release, the sealing plate remains open under buoyancy, not affecting normal irrigation operations. If the gate fails to close due to malfunction or forgetfulness, and the water level in the upstream field continues to drop, the float descends accordingly, causing the sealing plate to move synchronously, fundamentally preventing water from entering the field. Despite continuous water loss, this purely mechanical automatic protection structure does not rely on an external power source, ensuring high reliability and wide adaptability. By automatically intercepting the water at the warning level, it ensures that a certain amount of water layer is always maintained in the upper paddy field to protect seedlings. Even if the gate is left open overnight, the entire field will not dry up, effectively avoiding serious consequences such as crop death and yield reduction caused by water shortage, thus saving farmers from potentially huge economic losses. Furthermore, the maximum stroke movement of the gate can further limit the blocking plate, thereby achieving another working mode. When it is necessary to drain the water level of the upper paddy field, the blocking plate will not have an obstruction effect, thereby improving the functionality of this equipment.

[0007] In a preferred embodiment, a base is fixedly installed on the outer side of the back plate, the gate is slidably installed between the back plate and the base, a rack is provided on the outer side of the gate, gears are distributed in the middle of the base, the gears and the rack are meshed and connected, a motor is fixedly installed on the outer side of the base, and the output end of the motor is fixedly connected to the gears.

[0008] A base structure is further provided along the outer side of the back plate. The motor on the outer side of the base drives the additional gear and rack structure to move, thereby causing the gate to move vertically, controlling the opening and closing range of the drain pipe and maintaining the integrity of the equipment operation.

[0009] In a preferred embodiment, the top of the gate is provided with a handle groove for easy gripping by the user.

[0010] By further providing a handle groove structure along the top of the gate, workers can manually pull the gate by holding the handle groove, thereby improving the functionality and convenience of the equipment during use.

[0011] In a preferred embodiment, the back plate has a recessed area on its side, the gate is slidably distributed inside the recessed area, and a sliding groove is provided through the side of the back plate, the extruder is slidably distributed inside the sliding groove.

[0012] The recessed section structure along the inside of the back plate provides more space for the installation of the gate. At the same time, the back plate is further provided with a sliding groove structure, which provides space for the movement of the extrusion component when the gate moves vertically, thereby maintaining the integrity of the equipment operation.

[0013] In a preferred embodiment, the top of the sealing plate is provided with a bend, and the bend is engaged with the extrusion member. The bottom end of the sealing plate and the float are elastically connected by a number of elastic sheets.

[0014] By incorporating a bend structure along the top of the sealing plate, the extrusion component, in conjunction with the bend, drives the sealing plate to move vertically. Simultaneously, the sealing plate and the float are connected by a sliding connection and a flexible connection is formed by an elastic sheet. While the extrusion component pulls the sealing plate, it also provides a further stroke for the sealing plate to move, thereby improving the drainage capacity and functionality of the equipment.

[0015] As can be seen from the above, the smart agricultural irrigation system based on the Internet of Things provided by the present invention has the following technical effects.

[0016] Firstly, based on the traditional technology for intelligent irrigation control, the original bottom-up opening gate is retained, and a sealing plate structure driven by a float is added. During normal water release operations, the sealing plate remains open under the action of buoyancy, without affecting normal irrigation operations. If the gate fails to close due to malfunction or forgetfulness, and the water level in the upper field continues to drop, the float will drop accordingly and drive the sealing plate to move synchronously, fundamentally preventing the continuous loss of water. This purely mechanical automatic protection structure does not rely on an external power source, has high reliability, and wide adaptability.

[0017] Secondly, by automatically intercepting the water at the warning level, a certain amount of water layer is always maintained in the upper paddy fields to protect the seedlings. Even if the gate is left open overnight, the entire field will not dry up, effectively avoiding serious consequences such as crop death and reduced yield caused by water shortage, and saving farmers from potential huge economic losses.

[0018] Thirdly, by utilizing the maximum stroke movement of the gate, the sealing plate can be further limited, thereby achieving another working mode. When it is necessary to completely drain the water level of the upper field, the sealing plate structure of this equipment will not have an obstruction effect, thus improving the functionality of this equipment.

[0028] 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.

[0029] The present invention discloses an Internet of Things-based smart agricultural irrigation system, which is mainly applied to the intelligent irrigation of paddy fields.

[0030] Reference Figures 1 to 8 A smart agricultural irrigation system based on the Internet of Things includes a drain pipe 1, with a control component 2 for controlling irrigation installed at the end of the drain pipe 1; and a protective component 3 for protecting against water leakage is provided between the inside of the drain pipe 1 and the control component 2. The control component 2 includes a back plate 201 fixedly installed at the end of the drain pipe 1, and a gate 203 is slidably installed on the side of the back plate 201. The gate 203 is distributed on the outside of the drain pipe 1. The protective component 3 includes a sealing sleeve 301 fixedly installed inside the drain pipe 1. The sealing sleeve 301 is attached to the side wall of the back plate 201. A float 302 is floatingly distributed inside the sealing sleeve 301. A sealing plate 303 is slidably installed inside the float 302. The sealing plate 303 extends through the top of the float 302, the sealing sleeve 301, and the drain pipe 1. A pressing member 304 is fixedly installed on the back of the gate 203. The pressing member 304 and the sealing plate 303 are pressed and contacted when the gate moves vertically.

[0031] In this embodiment: During operation, the user remotely controls the gate 203 to move vertically along the side of the back plate 201. The moving gate 203 causes the drain pipe 1 to be in an open state, draining water from the upper-level field to the lower-level field. At this time, the inside of the drain pipe 1 is filled with irrigation water, and the float 302, under the action of buoyancy, drives the sealing plate 303 to float on the top of the drain pipe 1 until the drainage volume of the upper-level field exceeds the threshold. At this time, as the upper-level field continues to drain water, the water level inside the drain pipe 1 will drop synchronously, and the float 302 will drive the sealing plate 303 to drop along with the water level until the bottom of the sealing sleeve 301 is sealed. At this time, the drain pipe 1 can no longer drain water, thus completing the self-protection of the water level of the upper-level field. The specific state is as shown in the attached figure. Figure 6 As shown; when the user needs to drain the water level of the upper field, the user remotely controls the gate 203 to move vertically along the side of the back plate 201 to its maximum stroke. During this process, the pressing member 304 located on the back of the gate 203 will move synchronously and pull on the top of the sealing plate 303, so that the sealing plate 303 cannot descend when the drain pipe 1 is performing drainage operations. The specific state is shown in the attached figure. Figure 7 As shown.

[0032] Reference Figures 1 to 7 In a preferred embodiment, a base 202 is fixedly installed on the outer side of the back plate 201, and a gate 203 is slidably installed between the back plate 201 and the base 202. A rack 204 is provided on the outer side of the gate 203, and a gear 205 is distributed in the middle of the base 202. The gear 205 and the rack 204 are meshed and connected. A motor 206 is fixedly installed on the outer side of the base 202, and the output end of the motor 206 is fixedly connected to the gear 205.

[0033] During operation, the user remotely controls the motor 206 to start, which drives the gear 205 to rotate. The rotating gear 205 pushes the gate 203 through the rack 204, causing the gate 203 to move vertically along the side of the back plate 201. The moving gate 203 causes the drain pipe 1 to be in an open state and drain water from the upper field to the lower field.

[0034] The gate 203 is equipped with a handle groove 2031 on the top for easy gripping by the user. Workers can manually control the gate 203 by holding the handle groove 2031 and pulling it.

[0035] Specifically, the back plate 201 has a recessed section 2011 on its side, the gate 203 is slidably distributed inside the recessed section 2011, and the back plate 201 has a sliding groove 2012 through it, the extrusion member 304 is slidably distributed inside the sliding groove 2012.

[0036] Reference Figures 2 to 8 In a preferred embodiment, the top of the sealing piece 303 is provided with a bend 3031, and is engaged with the extruder 304 through the bend 3031. The bottom end of the sealing piece 303 and the float 302 are elastically connected through a plurality of elastic pieces 305.

[0037] When the user needs to drain the water level of the upper-level field, the user remotely controls the gate 203 to move vertically along the side of the back plate 201 to its maximum stroke. During this process, the pressing member 304 located on the back of the gate 203 will move synchronously and pull the bend 3031 at the top of the sealing plate 303, causing the sealing plate 303 to deform along the elastic plate 305 and move further upward along the interior of the float 302. When the drain pipe 1 is draining water, the sealing plate 303 cannot descend. The specific state is as shown in the attached figure. Figure 7 As shown.

[0038] The inner wall of the plugging sleeve 301 is provided with a sealing edge 3011, which fits against the side wall of the plugging piece 303 to maintain the sealing of the inside of the plugging sleeve 301 after it is lowered.

[0039] Working principle: During use, the user remotely controls the motor 206 to start. The motor 206 drives the gear 205 to rotate. The rotating gear 205 pushes the gate 203 through the rack 204, causing the gate 203 to move vertically along the side of the back plate 201. The moving gate 203 causes the drain pipe 1 to be in an open state, draining water from the upper field to the lower field. At this time, the inside of the drain pipe 1 is filled with irrigation water. Under the action of buoyancy, the float 302 drives the sealing plate 303 to float on the top of the drain pipe 1 until the drainage volume of the upper field exceeds the threshold. At this time, as the upper field continues to drain water, the water level inside the drain pipe 1 will drop synchronously. The float 302 will drive the sealing plate 303 to drop with the water level until the bottom of the sealing sleeve 301 is sealed. At this time, the drain pipe 1 can no longer drain water, thus completing the self-protection of the water level of the upper field. The specific state is as shown in the attached figure. Figure 6 As shown; when the user needs to drain the water level of the upper field, the user remotely controls the gate 203 to move vertically along the side of the back plate 201 to its maximum stroke. During this process, the squeezing member 304 located on the back of the gate 203 will move synchronously and pull the bend 3031 at the top of the sealing plate 303, causing the sealing plate 303 to deform and move further upward along the interior of the float 302. When the drain pipe 1 is performing drainage operations, the sealing plate 303 cannot descend. The specific state is shown in the attached figure. Figure 7 As shown.

[0040] It is worth noting that the diameter of the drainage pipe 1 can be customized according to the water storage depth of the field. It can be not only tubular but also in other shapes. The water storage depth in the field is directly reflected in the drainage pipe 1.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
