Description

Technical Field

[0001] This invention relates to the field of intelligent water-saving sprinkler head technology, and in particular to an intelligent sprinkler regulation method and device linked to the Internet of Things. Background Technology

[0002] The sprinkler head is one of the most important components of a sprinkler system. Its main function is to spray pressurized water into the air, forming fine water droplets that evenly cover the irrigated area. The sprinkler head can be installed on fixed or mobile pipelines and can effectively distribute water to lawns, farmland and other places to ensure that plants receive the water they need.

[0003] Existing sprinkler heads utilize a reduction gear mechanism to drive the oscillation, and this mechanism maintains a constant transmission ratio, meaning the meshing positions of the multiple reduction gears remain unchanged. When water pressure is high, the water-driven rotation speed is high, and even after reduction by the gear mechanism, the speed is still relatively fast compared to normal. This high oscillation speed of the sprinkler head exacerbates mechanical wear, leading to a reduced overall service life. Conversely, when water pressure is low, the water-driven rotation speed is slow, and even after reduction by the gear mechanism, the speed is still relatively slow compared to normal, resulting in an excessively low oscillation frequency. This affects the uniformity of irrigation, reduces the quality of irrigation, and can cause waterlogging in some areas due to prolonged irrigation time. This not only affects plant growth but also results in the ineffective consumption of water resources, severely reducing the quality of irrigation and water-saving efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide an intelligent sprinkler regulation method and device that is linked to the Internet of Things to address the problem that the oscillation of the sprinkler head is easily affected by the water pressure, resulting in poor sprinkler quality or reduced overall service life.

[0005] The above objectives are achieved through the following technical solution: An IoT-linked smart sprinkler regulation device includes: A fixed frame is set on the ground. A water supply pipe is connected to the fixed frame and a sprinkler pipe is rotatably mounted on it. The water supply pipe is connected to the sprinkler pipe. The sprinkler pipe has multiple spray holes and swings back and forth to irrigate the plants. A rotating sleeve is rotatably mounted on the fixed frame and coaxially fixedly connected to the irrigation pipe. A water wheel is coaxially rotatably connected inside the rotating sleeve. The water wheel is connected to the fixed frame by a speed reduction transmission. The rotating sleeve is connected to the water delivery pipe. A reversing assembly, the reversing assembly being used to change the rotation direction of the water wheel to change the swing direction of the sprinkler pipe; An adjustment component is configured to increase the deceleration ratio when the water pressure increases and decrease the deceleration ratio when the water pressure decreases.

[0006] Furthermore, the adjustment assembly includes a first transmission cone wheel, a second transmission cone wheel, a transmission wheel, and an elastic sliding plate. Both the first and second transmission cone wheels are rotatably mounted within a rotating sleeve, and their axes are parallel to each other. The large end of the first transmission cone wheel and the small end of the second transmission cone wheel face the same direction. The small end of the first transmission cone wheel is connected to a water turbine speed reducer, and the small end of the second transmission cone wheel is connected to a fixed frame. The elastic sliding plate is slidably mounted within the rotating sleeve along the axial direction of the first transmission cone wheel. The plane of the elastic sliding plate is perpendicular to the water flow direction. Multiple through holes are provided on the elastic sliding plate to allow water flow. The transmission wheel is mounted on the elastic sliding plate, and the outer circumference of the rotating wheel is in frictional contact with the outer circumferences of the first and second transmission cone wheels. The elastic sliding plate initially approaches the large end of the first transmission cone wheel and has a tendency to move towards the large end of the first transmission cone wheel.

[0007] Furthermore, a first elastic element is provided on the elastic sliding plate. One end of the first elastic element is connected to the elastic sliding plate, and the other end of the first elastic element is connected to the rotating sleeve. The first elastic element has a tendency to push the elastic sliding plate to reset.

[0008] Furthermore, the reversing assembly includes a first channel, a second channel, and a swing plate. Both the first channel and the second channel are connected to the water supply pipe and the sprinkler pipe. The first channel is closer to the water wheel side, and the second channel is closer to the water wheel side. The swing plate is rotatably disposed within the rotating sleeve, and the swing plate can block the first channel or the second channel.

[0009] Furthermore, a partition is provided inside the rotating sleeve, which divides the rotating sleeve into a first cavity and a second cavity. The first cavity is connected to the irrigation pipe, and the second cavity is connected to the water supply pipe. The water wheel is rotatably disposed in the first cavity. Both the first channel and the second channel are connected to the first cavity and the second cavity. A swing rod is provided inside the rotating sleeve, which is used to rotate the swing plate.

[0010] Furthermore, a pressure sensor and a flow sensor are provided inside the rotating sleeve. The pressure sensor is used to monitor water pressure, and the flow sensor is used to monitor water flow. A blockage clearing component is provided inside the rotating sleeve. The blockage clearing component is configured to increase the water flow to flush the nozzle when the nozzle is blocked.

[0011] Furthermore, the unblocking component includes an elastic plug, and a through groove is provided on the partition plate. The elastic plug is located in the second cavity and one end tends to block the through groove. The elastic plug is configured to open the through groove when the pressure in the second cavity increases.

[0012] Furthermore, a second elastic element is provided on the end of the elastic plug away from the partition plate, and the second elastic element has a tendency to push the elastic plug closer to the through groove.

[0013] Furthermore, the fixing frame is provided with a limiting component, which is used to limit the swing angle of the irrigation pipe.

[0014] This invention also provides an IoT-linked intelligent sprinkler regulation method, comprising the following steps: Step S100: Adjust the swing angle of the sprinkler pipe; Step S200: Connect the water source, and the sprinkler pipe will oscillate back and forth at a constant oscillation speed to adapt to the water pressure; Step S300: If the nozzle of the irrigation pipe is blocked, the pressure of the pressurized water inside the rotating sleeve is increased to flush out the blockage.

[0015] The beneficial effects of this invention are: This invention, by setting an adjustment component, enables the swing speed of the irrigation pipe to match changes in water pressure in real time. When the water pressure increases, the deceleration ratio is automatically increased to reduce the swing speed of the irrigation pipe, avoiding water splashing and deep leakage; when the water pressure decreases, the deceleration ratio is reduced to increase the swing speed, preventing local water accumulation, reducing ineffective water consumption at the source, and significantly improving water resource utilization.

[0016] This invention incorporates a pressure sensor, a flow sensor, and a blockage-clearing component. When the pressure sensor detects an increase in water pressure, but the flow sensor data shows no significant fluctuation, it indicates that the nozzles of the irrigation pipe are blocked. The high-pressure water inside the rotating sleeve automatically flushes away the blockage, preventing irrigation interruptions and water waste caused by blockages, and maintaining stable water-saving conditions.

[0022] The following reference Figures 1-13 This invention describes an IoT-linked intelligent sprinkler regulation device.

[0023] An IoT-linked intelligent sprinkler irrigation adjustment device, suitable for adjusting sprinkler heads, includes a fixed frame 100, a water supply pipe 110 connected to the fixed frame 100, and a sprinkler pipe 120 rotatably connected thereto. Multiple spray holes 130 are formed on the outer periphery of the sprinkler pipe 120, evenly distributed along the axial direction of the sprinkler pipe 120. This even distribution ensures uniform water coverage and avoids water waste caused by localized over-irrigation. The sprinkler pipe 120 is connected to the water supply pipe 110, which delivers pressurized water to the sprinkler pipe 120, which then sprays water from the multiple spray holes 130 to irrigate plants. To allow the sprinkler pipe 120 to rotatably connect to the fixed frame 100, a rotating sleeve 200 is rotatably mounted on the fixed frame 100. The rotating sleeve 200 is coaxial with and fixedly connected to the sprinkler pipe 120, and can drive the sprinkler pipe 120 to swing. The rotating sleeve 200 is coaxially connected to a water wheel 210 inside the 00. The water wheel 210 drives the rotating sleeve 200 to rotate as a whole. Specifically, when the pressurized water in the water pipe 110 passes through the rotating sleeve 200, it can drive the water wheel 210 to rotate. The water wheel 210 is connected to the fixed frame 100 by a speed reduction transmission. Specifically, a speed reduction mechanism is set between the water wheel 210 and the fixed frame 100. When the faster rotation speed of the water wheel 210 is transmitted to the fixed frame 100 after passing through the speed reduction mechanism, the rotation speed is very slow. Thus, the water wheel 210 drives the rotating sleeve 200 to rotate slowly. Furthermore, a reversing component is set inside the rotating sleeve 200 to change the rotation direction of the water wheel 210. This causes the rotating sleeve 200 to drive the sprinkler pipe 120 to swing back and forth, achieving full coverage of the irrigation area and avoiding repeated irrigation due to missed coverage. This achieves water conservation from the perspective of controlling the irrigation range.

[0024] However, the reduction mechanisms used in existing technologies all have a constant transmission ratio, meaning that the meshing positions of the multiple reduction gears in the reduction mechanism do not change. When the pressure of the pressurized water is high, the pressurized water drives the water wheel 210 to rotate faster. Even after being reduced by the reduction mechanism, the speed is still faster than the normal speed. When the oscillation speed of the irrigation pipe 120 is high, it aggravates mechanical wear, thus reducing the overall service life. Conversely, when the pressure of the pressurized water is low, the pressurized water drives the water wheel 210 to rotate slower. Even after being reduced by the reduction mechanism, the speed is still slower than the normal speed, resulting in an excessively low oscillation frequency of the irrigation pipe 120. This affects the uniformity of irrigation and reduces the irrigation quality of the irrigation pipe 120. In some areas, water accumulation may occur due to excessively long irrigation times, which not only affects plant growth but also causes ineffective water consumption, seriously reducing the irrigation quality and water-saving efficiency of the irrigation pipe 120.

[0025] Based on this, to minimize changes in the oscillation frequency of the irrigation pipe 120 when pressurized water actuates the water wheel 210 at different speeds under varying pressures, the present invention includes an adjustment component within the rotating sleeve 200. This adjustment component replaces the reduction gear mechanism in the prior art. The adjustment component is configured to increase the reduction ratio between the water wheel 210 and the fixed frame 100 when the pressurized water pressure increases. This reduces the oscillation speed of the irrigation pipe 120 when the water wheel 210 rotates at a high speed, thus minimizing fluctuations in the oscillation speed of the irrigation pipe 120 and preventing further changes. The excessively fast swing speed of the sprinkler pipe 120 reduces mechanical wear, while ensuring a stable irrigation volume per unit area and preventing water splashing and waste caused by sudden pressure increases. When the pressurized water pressure decreases, the reduction ratio between the water wheel 210 and the fixed frame 100 decreases, thereby increasing the swing speed of the sprinkler pipe 120 when the water wheel 210 is moving slowly. This minimizes fluctuations in the speed of the sprinkler pipe 120, preventing overlapping irrigation water accumulation caused by slow swing speeds. This fundamentally reduces ineffective water consumption and improves sprinkler irrigation quality and water-saving effects.

[0026] Specifically, the adjustment assembly in this embodiment includes a first transmission cone wheel 230, a second transmission cone wheel 240, a transmission wheel 250, and an elastic sliding plate 260, such as... Figure 11 and Figure 12 As shown, both the first transmission cone wheel 230 and the second transmission cone wheel 240 are rotatably mounted within the rotating sleeve 200, and their axes are parallel to each other. The large end of the first transmission cone wheel 230 and the small end of the second transmission cone wheel 240 face the same direction. The small end of the first transmission cone wheel 230 is connected to the water wheel 210 via a first transmission gear 211 and a second transmission gear 212. The first transmission gear 211 is coaxial and fixedly connected to the water wheel 210, and the second transmission gear 212 is coaxial and fixedly connected to the small end of the first transmission cone wheel 230. The diameter of the first transmission gear 211 is much smaller than the diameter of the water wheel 210, and the second transmission wheel... The diameter of gear 250 is larger than that of the first transmission gear 211. The meshing of the first transmission gear 211 and the second transmission gear 212 can reduce speed and simultaneously connect the small end of the first transmission cone wheel 230 to the water wheel 210. The second transmission cone wheel 240 is connected to the fixed frame 100. Specifically, a fixed gear 220 is fixedly installed on the fixed frame 100. A third transmission gear 241 is coaxially and fixedly connected to the small end of the second transmission cone wheel 240. The third transmission gear 241 meshes with the fixed gear 220, thereby connecting the small end of the second transmission cone wheel 240 to the fixed frame 100.

[0027] To change the transmission ratio between the first transmission cone wheel 230 and the second transmission cone wheel 240, an elastic sliding plate 260 is slidably disposed below the first transmission cone wheel 230 and the second transmission cone wheel 240, and a transmission wheel 250 is slidably disposed on the elastic sliding plate 260. The plane of the elastic sliding plate 260 is perpendicular to the direction of water flow, that is, the plane of the elastic sliding plate 260 is perpendicular to the axis of the first transmission cone wheel 230 and the second transmission cone wheel 240. The elastic sliding plate 260 can slide along the axial direction of the first transmission cone wheel 230. The elastic sliding plate 260 has multiple through holes 261 that allow pressurized water to pass through. Under normal pressurized water pressure, the elastic sliding plate 260 will move a fixed distance closer to the water wheel 210. If the pressurized water pressure increases, the distance the sliding plate moves closer to the water wheel 210 will increase. If the pressurized water pressure decreases, the elastic sliding plate 260 will move a certain distance away from the water wheel 210, thus enabling the elastic sliding plate 260 to move according to the pressure change of the pressurized water. The outer periphery of the transmission wheel 250 is in frictional contact with the outer periphery of the first transmission cone wheel 230 and the second transmission cone wheel 240. The initial position of the transmission wheel 250 is close to the large end of the first transmission cone wheel 230 and the small end of the second transmission cone wheel 240, and the elastic sliding plate 260 has a tendency to drive the transmission wheel 250 closer to the large end of the first transmission cone wheel 230.

[0028] It should be noted that the large end position of the first transmission cone wheel 230 is the position of the transmission wheel 250 under normal pressurized water pressure. At this time, the water wheel 210 drives the sprinkler pipe 120 to swing at a relatively normal speed after being decelerated by the first transmission cone wheel 230 and the second transmission cone wheel 240. If the pressurized water pressure increases, the force of the pressurized water acting on the elastic sliding plate 260 increases, thus pushing the elastic sliding plate 260 to move closer to the water wheel 210. This causes the elastic sliding plate 260 to drive the transmission wheel 250 to move from the large end to the small end of the first cone wheel. Since the first transmission cone wheel 230 is driven by the water wheel 210, and the second transmission cone wheel 240 is driven by the first transmission cone wheel 230, the speed of the transmission wheel 250 decreases during the movement. This, in turn, reduces the speed at which the transmission wheel 250 drives the second transmission cone wheel 240. Because the transmission wheel 250 moves from the small end to the large end of the second transmission cone wheel 240, the rotational speed of the second transmission cone wheel 240 decreases even more, causing the first transmission gear 21 on the first transmission cone wheel 230 to... While the first and second transmission gears 211 and 212 reduce speed, the transmission wheel 250 and the second transmission cone wheel 240 increase the overall reduction ratio, minimizing fluctuations in the oscillation speed of the irrigation pipe 120. If the pressure of the pressurized water decreases, the force exerted by the pressurized water on the elastic sliding plate 260 decreases, causing the elastic sliding plate 260 to move the transmission wheel 250 away from the water wheel 210. At this time, the transmission wheel 250 moves towards the larger end on the first transmission cone wheel 230, increasing its rotational speed. The transmission wheel 250 moves towards the smaller end on the second transmission cone wheel 240, further increasing its rotational speed. This, in turn, increases the speed of the irrigation pipe 120 driven by the rotating sleeve 200. As a result, while the first transmission gear 211 and 212 on the first transmission cone wheel 230 reduce speed, the transmission wheel 250 and the second transmission cone wheel 240 reduce the overall reduction ratio, minimizing fluctuations in the oscillation speed of the irrigation pipe 120.

[0029] More specifically, such as Figure 11 and Figure 12 As shown, in order to make the elastic sliding plate 260 tend to move towards the large end of the first transmission cone wheel 230, this embodiment provides a first elastic element 270 on the end face of the elastic sliding plate 260 near the water wheel 210. The first elastic element 270 is a compression spring, and there are two first elastic elements 270. One end of the two first elastic elements 270 is fixed on the end face of the elastic sliding plate 260 near the water wheel 210, and the other end of the two first elastic elements 270 is fixed inside the rotating sleeve 200. The two first elastic elements 270 push the elastic sliding plate 260 to move away from the water wheel 210, that is, push the elastic sliding plate 260 to move towards the large end of the first transmission cone wheel 230.

[0030] It should be noted that in this embodiment, the transmission wheel 250 can slide on the elastic sliding plate 260, thereby adapting to the inclined channel between the first transmission cone wheel 230 and the second transmission cone wheel 240, as shown in the specific state. Figure 12 and Figure 13 As shown, the elastic sliding plate 260 is provided with a slide rail 262, and the transmission wheel 250 can slide in the slide rail 262. The outer periphery of the transmission wheel 250 is always in frictional contact with the outer periphery of the first transmission cone wheel 230 and the second transmission cone wheel 240.

[0031] In a further embodiment, the reversing component of the present invention includes a first channel, a second channel, and a swing plate 330. Both the first channel and the second channel are connected to the water supply pipe 110 and the irrigation pipe 120. The first channel is closer to the side of the water wheel 210, and the second channel is closer to the other side of the water wheel 210. When pressurized water passes through the first channel, it will cause the water wheel 210 to rotate. When pressurized water passes through the second channel, it will cause the water wheel 210 to rotate in the opposite direction. In order to ensure that the water wheel 210 can rotate, pressurized water needs to pass through only the first channel or the second channel. When changing the rotation direction of the water wheel 210, the channel through which the pressurized water passes can be changed. Therefore, the swing plate 330 is rotatably set inside the rotating sleeve 200. The swing plate 330 can block the first channel or the second channel. When it is necessary to change the rotation direction of the water wheel 210, the swing plate 330 is rotated to change the blocking target of the swing plate 330. The pressurized water changes the channel, thereby changing the rotation direction of the water wheel 210.

[0032] Specifically, such as Figure 9 and Figure 10 As shown, a partition 300 is provided inside the rotating sleeve 200, which divides the rotating sleeve 200 into a first cavity 301 and a second cavity 302. The first cavity 301 is connected to the irrigation pipe 120, and the second cavity 302 is connected to the water supply pipe 110. A first water inlet 310 and a second water inlet 320 are provided on the partition 300. A baffle 303 is provided on the partition 300, which separates the first water inlet 310 and the second water inlet 320 to form a first channel and a second channel. The water wheel 210 is rotatably disposed in the first cavity 301. The middle of the water wheel 210 is hollow to allow pressurized water to pass through. When pressurized water passes through the first channel or the second channel, it will enter the irrigation pipe 120 from the middle of the water wheel 210, so that the pressurized water can both drive the water wheel 210 to rotate and spray out through the nozzle 130 of the irrigation pipe 120.

[0033] More specifically, in order for the swing plate 330 to block the first channel or the second channel, that is, to block the first water inlet 310 or the second water inlet 320, a swing rod 340 is also provided inside the rotating sleeve 200 in this embodiment, such as... Figure 4 and Figure 5As shown, a hinge ball is provided at the middle position of the swing rod 340. The hinge ball is connected inside the rotating sleeve 200. One end of the swing rod 340 can deflect the swing plate 330. Two baffles 350 are provided on the end of the swing plate 330 near the swing rod 340. One end of the swing rod 340 extends between the two baffles 350, and the other end of the swing rod 340 extends out of the rotating sleeve 200. Two stops 400 are provided on the fixing frame 100. When the rotating sleeve 200 drives the irrigation pipe 120 to swing in one direction and contact one of the stops 400, the rotating sleeve 200 continues to rotate, so that the swing rod 340 rotates around the hinge ball at a certain angle under the action of the stop 400. At this time, the other end of the swing rod 340 deflects the swing plate 330 to rotate and block the first water inlet 310 or the second water inlet 320. For example, when one end of the swing plate 330 blocks the second water inlet 320, the other end of the swing plate 330 opens the first water inlet 310. At this time, the pressurized water passes through the first channel and drives the water wheel 210 to rotate. The water wheel 210 drives the rotating sleeve 200 to rotate relative to the fixed frame 100. The rotating sleeve 200 drives the irrigation pipe 120 to rotate. When the swing rod 340 extending from the rotating sleeve 200 contacts the stop block 400 on the fixed frame 100, it indicates that the irrigation pipe 120 has changed direction. At this time, the swing rod 340 is pushed by the stop block 400 to rotate around the hinge ball. The other end of the swing rod 340 pushes the swing plate 330 to block the first water inlet 310 and open the second water inlet 320, so that the pressurized water passes through the second channel and drives the water wheel 210 to rotate to change the swing direction of the irrigation pipe 120. Similarly, when the irrigation pipe 120 swings in another direction and needs to change direction, the principle of changing direction is the same as the above principle, and will not be described in detail.

[0034] In a further embodiment, a pressure sensor (not shown in the figure) and a flow sensor (not shown in the figure) are provided inside the rotating sleeve 200 of the present invention. The pressure sensor is used to monitor the pressure of the pressurized water, while the flow sensor is used to monitor the water flow rate of the pressurized water. When the pressure sensor detects an increase in the pressure of the pressurized water, but the water flow rate of the flow sensor does not change, it indicates that the nozzle 130 on the irrigation pipe 120 is blocked. At this time, the nozzle 130 needs to be cleared. Therefore, a clearing component is provided inside the rotating sleeve 200 to deal with the blockage of the nozzle 130.

[0035] Specifically, the unblocking component in this invention includes an elastic plug 370, such as... Figure 6As shown, a through groove 360 ​​is provided on the partition 300. The through groove 360 ​​is located above the first water inlet 310 and the second water inlet 320. An elastic plug 370 is located in the second cavity 302. One end of the elastic plug 370 has a tendency to block the through groove 360. One end of the elastic plug 370 can extend into the through groove 360 ​​to block the through groove 360. The elastic plug 370 is configured to open the through groove 360 ​​when the pressure in the second cavity 302 increases, so that the pressurized water with higher pressure in the second cavity 302 can quickly enter the first cavity 301, thereby increasing the water pressure in the first cavity 301. The higher water pressure in the first cavity 301 can clear the blocked nozzle 130.

[0036] More specifically, such as Figure 9 and Figure 10 As shown, in this embodiment, a second elastic element 380 is provided on the end of the elastic plug 370 away from the partition plate 300. The second elastic element 380 is a compression spring. One end of the second elastic element 380 is fixedly connected to the end of the elastic plug 370 away from the partition plate 300, and the other end of the second elastic element 380 is connected to the elastic sliding plate 260. In this embodiment, a sleeve 390 is fixedly provided on the elastic sliding plate 260. The elastic plug 370 is axially slidably disposed in the sleeve 390, and the second elastic element 380 is located inside the sleeve 390. When the water pressure in the second cavity 302 increases, it indicates that... When the nozzle 130 on the sprinkler pipe 120 becomes blocked, the water pressure in the first cavity 301 increases, causing the pressurized water in the first cavity 301 to push the elastic plug 370. The elastic plug 370 overcomes the force of the second elastic element 380 and disengages from the through groove 360. At this time, the pressurized water with higher pressure in the second cavity 302 will quickly enter the first cavity 301 through the through groove 360. The water pressure in the first cavity 301 increases rapidly in a short time, which can flush out the blockage in the nozzle 130 and prevent the nozzle 130 from being blocked for a long time.

[0037] In a further embodiment, in order to make the swing angle of the irrigation pipe 120 adjustable, the present invention provides a limiting component on the fixing frame 100. The limiting component is used to limit the swing angle of the irrigation pipe 120, which can make the irrigation pipe 120 swing back and forth within a small angle or swing back and forth within a large angle.

[0038] Specifically, the limiting component includes a first limiting ring 410 and a second limiting ring 420. The first limiting ring 410 and the second limiting ring 420 are coaxial and rotatably connected to the fixed frame 100. Two stops 400 are respectively set on the first limiting ring 410 and the second limiting ring 420. When the first limiting ring 410 and the second limiting ring 420 rotate relative to each other, the distance between the two stops 400 can be adjusted, thereby changing the swing angle of the irrigation pipe 120.

[0039] It is understandable that if the relative rotation of the first limiting ring 410 and the second limiting ring 420 reduces the distance between the two stops 400, the swing rod 340 extending from the rotating sleeve 200 will touch the stop 400 before the irrigation pipe 120 swings by much angle, thus changing the swing direction of the irrigation pipe 120. If the relative rotation of the first limiting ring 410 and the second limiting ring 420 increases the distance between the two stops 400, the swing rod 340 extending from the rotating sleeve 200 will only touch the stop 400 and change direction when the irrigation pipe 120 swings by a larger angle. Therefore, adjusting the distance between the two stops 400 can adjust the swing angle of the irrigation pipe 120.

[0040] More specifically, in order to enable the two stops 400 to push the swing arm 340 and to prevent the two stops 400 from shifting after adjustment, the first limiting ring 410 in this embodiment is provided with a first paddle 411 on its outer periphery, and the second limiting ring 420 is provided with a second paddle 421 on its outer periphery. Limiting grooves 430 are provided on the outer periphery of both the first limiting ring 410 and the second limiting ring 420. The first paddle 411 is fixed to the outer periphery of the first limiting ring 410 and can be engaged in the limiting groove 430 on the outer periphery of the second limiting ring 420. The second paddle 421 is fixed to the outer periphery of the second limiting ring 420 and can be engaged in the limiting groove 430 on the outer periphery of the first limiting ring 410. When it is necessary to adjust the distance between the two stops 400, the operator can forcefully paddle the first paddle 411 and the second paddle 421, causing the first limiting ring 410 and the second limiting ring 420 to rotate relative to each other, thereby adjusting the distance between the two stops 400. To prevent the first limiting ring 410 and the second limiting ring 420 from rotating synchronously with the rotating sleeve 200, a fixed sleeve 440 is also provided on the fixed frame 100. The fixed sleeve 440 has teeth on its outer circumference, and the first limiting ring 410 and the second limiting ring 420 also have teeth on their inner circumference. The first limiting ring 410 and the second limiting ring 420 are engaged with the fixed sleeve 440 by the teeth. Only when the operator forcefully moves the first lever 411 and the second lever 421 can the first limiting ring 410 and the second limiting ring 420 rotate relative to the fixed sleeve 440. When the sprinkler pipe 120 is working normally, the first limiting ring 410 and the second limiting ring 420 do not rotate relative to the fixed sleeve 440.

[0041] The specific working process of the IoT-linked intelligent sprinkler regulation device provided by the present invention will be described in conjunction with the above embodiments: Adjust the swing angle of the sprinkler pipe 120 according to the plant growth status: The operator forcefully moves the first lever 411 and the second lever 421 to make the first limiting ring 410 and the second limiting ring 420 rotate relative to the fixed sleeve 440, thereby adjusting the distance between the two stops 400. The distance between the two stops 400 determines the swing angle of the sprinkler pipe 120.

[0042] After adjusting the angle, start spraying: Water supply pipe 110 is connected to a water source. Pressurized water enters the second cavity 302 of rotating sleeve 200 through the through hole 261 on elastic sliding plate 260 via water supply pipe 110. Then it enters the first cavity 301 through the first water inlet 310 on partition plate 300. Since the first water inlet 310 is located on one side of the outer circumference of water wheel 210, pressurized water will flow through the outer circumference of water wheel 210 when it passes through the first water inlet 310, thereby causing water wheel 210 to rotate around its own axis. Pressurized water then enters the sprinkler pipe 120 through the middle of water wheel 210, and finally sprays out from the spray hole 130 on the outer circumference of sprinkler pipe 120 to irrigate plants. When pressurized water drives the waterwheel 210 to rotate, the waterwheel 210 drives the first transmission cone wheel 230 through the first transmission gear 211 and the second transmission gear 212. After being decelerated by the first transmission gear 211 and the second transmission gear 212, the rotation speed of the first transmission cone wheel 230 is relatively slow. The transmission wheel 250 on the outer periphery of the first transmission cone wheel 230 also makes frictional contact with the outer periphery of the second transmission cone wheel 240. The third transmission gear 241 on the second transmission cone wheel 240 meshes with the fixed gear 220 on the fixed frame 100. The third transmission gear 241 revolves around the axis of the fixed gear 220. Due to the deceleration of the first transmission gear 211 and the second transmission wheel 230, the rotation speed of the first transmission cone wheel 230 is relatively slow. The moving cone wheel 240 is rotatably connected inside the rotating sleeve 200, so the third transmission gear 241 also drives the rotating sleeve 200 to rotate around the axis of the rotating sleeve 200. The rotating sleeve 200 drives the sprinkler pipe 120 to swing. When it swings to a certain angle, the swing rod 340 extending from the rotating sleeve 200 will touch the stop block 400. The stop block 400 pushes the swing rod 340 to rotate around the hinge ball on it. The other end of the swing rod 340 pushes the swing plate 330 to rotate, thereby blocking the first water inlet 310. Pressurized water flows out from the second water inlet 320. The pressurized water pushes the water wheel 210 to rotate in the opposite direction, thereby changing the swing direction of the sprinkler pipe 120.

[0043] When the pressure of the pressurized water fluctuates: If the pressure of the pressurized water increases, when the pressurized water flows from the water pipe 110 through the through hole 261 on the elastic sliding plate 260, the pushing force of the pressurized water on the elastic sliding plate 260 will increase due to the higher pressure. Most of the pressurized water will still enter the second cavity 302 through the through hole 261 on the elastic sliding plate 260. At the same time, the increased pressure of the water flow on the elastic sliding plate 260 pushes it to move axially. The pressurized water with higher pressure enters the first cavity 301, increasing the rotation speed of the water wheel 210. To prevent the water wheel 210 from rotating too fast and causing the sprinkler pipe 120 to swing too fast, the elastic sliding plate 260... It will move a certain distance towards the water wheel 210 until the force of the pressurized water is the same as the force of the first elastic element 270, at which point it stops moving. At this time, the transmission wheel 250 on the elastic sliding plate 260 moves synchronously. The transmission wheel 250 moves from the large end to the small end on the first transmission cone wheel 230. At this time, the rotation speed of the transmission wheel 250 will decrease, and then the reduced speed will be transmitted to the second transmission cone wheel 240, so that the speed at which the third transmission gear 241 drives the rotating sleeve 200 to rotate will decrease, thus increasing the overall reduction ratio and preventing the sprinkler pipe 120 from swinging too fast due to excessive pressurized water pressure.

[0044] If the pressure of the pressurized water decreases, when the pressurized water passes through the through hole 261 on the elastic sliding plate 260 from the water supply pipe 110, the elastic sliding plate 260 will move away from the water wheel 210 under the action of the first elastic element 270 until the force of the pressurized water is the same as the force of the first elastic element 270. The transmission wheel 250 on the elastic sliding plate 260 moves synchronously and moves towards the larger end on the first transmission cone wheel 230. At this time, the speed of the transmission wheel 250 increases, and then the increased speed is transmitted to the second transmission cone wheel 240, which increases the speed at which the third transmission gear 241 drives the rotating sleeve 200 to rotate, thereby reducing the overall reduction ratio. This avoids the irrigation pipe 120 from swinging too slowly due to the low pressure of the pressurized water, resulting in poor irrigation quality.

[0045] If the pressure sensor detects a high pressurized water pressure inside the rotating sleeve 200, but the flow sensor detects no significant fluctuation in water flow, it indicates that the nozzle 130 on the irrigation pipe 120 is blocked, leading to excessive water pressure inside the rotating sleeve 200. Consequently, the pressurized water in the first cavity 301 within the rotating sleeve 200 will also experience increased pressure due to the blocked nozzle 130. When the pressure in the first cavity 301 increases, it pushes the elastic plug 370 in the through groove 360 ​​of the baffle 300, causing the elastic plug 370 to gradually... The second elastic element 380 is compressed to open the through groove 360. The elastic plug 370 requires a certain pressure to open, which is relatively large. In addition, the pressurized water in the second cavity 302 increases the pressure. The pressurized water in the second cavity 302 will instantly enter the first cavity 301 through the through groove 360, which will increase the pressure in the second cavity 302 again. This will cause the internal pressure of the irrigation pipe 120 to increase sharply. The blockage in the nozzle 130 of the irrigation pipe 120 will be flushed out by the pressurized water with the increased pressure, thereby preventing the nozzle 130 from being blocked for a long time.

[0046] This invention also provides an IoT-linked intelligent sprinkler regulation method, which requires the aforementioned IoT-linked intelligent sprinkler regulation device and includes the following steps: Step S100: Adjust the swing angle of the sprinkler pipe 120; Among them, the swing angle of the sprinkler pipe 120 is adjusted according to the water requirement area of ​​the plant to achieve targeted irrigation and reduce ineffective water consumption.

[0047] Step S200: Connect the water source, and the sprinkler pipe 120 oscillates back and forth at a constant oscillation speed to adapt to the water pressure; Among them, the constant speed reciprocating oscillation of the sprinkler pipe at 120° ensures uniform irrigation and improves water resource utilization.

[0048] Step S300: If the nozzle 130 of the irrigation pipe 120 is blocked, the pressure of the pressurized water inside the rotating sleeve 200 is increased to flush out the blockage in the nozzle 130.

[0049] Among these measures, clearing blockages and restoring normal irrigation are crucial to preventing water waste and irrigation failure caused by blockages.
