Description

An intelligent water-saving irrigation device and method for landscaping maintenance Technical Field

[0001] This invention relates to the field of intelligent water-saving irrigation devices, and in particular to an intelligent water-saving irrigation device and method for landscaping maintenance. Background Technology

[0002] Garden irrigation is a technical measure to replenish soil moisture in garden green spaces through manual or mechanical means. It is mainly used to meet the growth needs of plants, and also has the functions of regulating temperature and humidity, cleaning plants, and beautifying the environment. The main methods include sprinkler irrigation, drip irrigation, micro-sprinkler irrigation, and individual plant irrigation, covering different vegetation types such as flowers, lawns, and trees.

[0003] Micro-sprinkler irrigation, also known as mist sprinkler irrigation, is an irrigation technology that uses a low-pressure pipeline system and micro-sprinklers to atomize and spray water. The principle is to use a low-pressure water pump and pipeline system to transport water. Under the action of low-pressure water, water is sprayed into the air through specially designed micro-atomizing nozzles and dispersed into fine mist droplets, which are then sprinkled on the branches and leaves of crops or the ground under the canopy to achieve irrigation.

[0004] However, if the water supply pressure of the existing micro-sprinkler irrigation system decreases, it will lead to a shorter spray distance, a smaller coverage area, and obvious irrigation blind spots. Some plants will not be able to receive water. If the water supply pressure is low for a long time, it will cause uneven plant growth. In arid areas, plants are prone to wilting, yellowing leaves, and withering, which seriously affects the quality of landscaping. Summary of the Invention

[0005] Therefore, it is necessary to provide an intelligent water-saving irrigation device and method for landscaping maintenance to address the problem that insufficient water pressure in current micro-sprinkler irrigation leads to shortened irrigation distances and affects the quality of landscaping.

[0006] The above objectives are achieved through the following technical solutions:

[0007] An intelligent water-saving irrigation device for landscaping maintenance includes:

[0008] Two parallel water pipes are connected by multiple micro-spray pipes. The multiple micro-spray pipes are parallel to each other and perpendicular to the two parallel water pipes. Multiple micro-spray holes are evenly opened on the outer periphery of the multiple micro-spray pipes.

[0009] A water storage tank is provided, which stores water to be irrigated. The water storage tank is connected to one end of two parallel water pipes. A water pump is installed in the water storage tank, and the water pump supplies water to the two parallel water pipes.

[0010] An adjustment component is provided, which is capable of adjusting the number of micro-jet nozzles that open, and is configured to reduce the number of micro-jet nozzles that open when the water pressure inside the water supply pipe decreases.

[0011] Furthermore, the adjustment assembly includes a shield and a drive component. The shield is rotatably disposed inside a plurality of micro-spray nozzles, and the drive component is used to drive the shield to rotate in order to block the micro-spray nozzles.

[0012] Furthermore, the driving component includes a drive motor, a rotating ring, and a magnet. The rotating ring is rotatably sleeved on the outer periphery of multiple micro-nozzles, and the magnet is fixedly mounted on the shielding plate. The drive motor is used to drive the rotating ring on the outer periphery of the multiple micro-nozzles to rotate. The rotating ring is magnetic, and the magnet can attract the rotating ring.

[0013] Furthermore, the baffle is elastic, and the width of the baffle is negatively correlated with the water pressure inside the water pipe.

[0014] Furthermore, the baffle includes an elastic baffle and two parallel sliding rods. The two parallel sliding rods are rotatably connected inside the micro-nozzle. Two parallel sliding rods are fixedly connected to both sides of the elastic baffle. The two parallel sliding rods are spaced apart from each other to increase the width of the elastic baffle.

[0015] Furthermore, the driving component has two sets, which are located at the two ends of two parallel sliding rods respectively. The two sets of driving components are configured to generate a speed difference when the water pressure inside the water pipe decreases to a preset value, thereby increasing the distance between the two parallel sliding rods.

[0016] Furthermore, the elastic strip is elastic.

[0017] Furthermore, a connecting sleeve is coaxially and fixedly installed inside the micro-nozzle, and an arc-shaped slide rail is provided on the connecting sleeve. Two parallel sliding rods are slidably disposed at one end inside the arc-shaped slide rail.

[0018] Furthermore, limiting rods are provided at both ends of the two parallel sliding rods, and the limiting rods are located inside the arc-shaped slide rail.

[0019] This invention also provides an intelligent water-saving irrigation method for garden greening maintenance, comprising the following steps:

[0020] Step S100: Start the water pump, which delivers water into two parallel water pipes. The water is then sprayed out through micro-spray holes on multiple micro-spray pipes to irrigate the garden plants.

[0021] Step S200: If the water pressure in the water supply pipe decreases, the adjusting component reduces the number of micro-sprinklers opened to maintain the original irrigation range of multiple micro-sprinklers.

[0022] The beneficial effects of this invention are:

[0023] This invention incorporates an adjustment component that automatically adjusts the number of micro-spray nozzles opened based on the water pressure in the water supply pipe. When the water pressure decreases, the number of water outlet channels is reduced, increasing the water pressure of the remaining nozzles. This compensates for the decrease in spray distance, avoids irrigation blind spots caused by water pressure drops in traditional irrigation, ensures uniform water replenishment for garden plants, prevents localized plants from wilting and dying due to water shortage, and guarantees the quality of landscaping.

[0024] This invention features a baffle with variable width, comprising two parallel sliding rods and an elastic baffle. The width of the baffle is negatively correlated with water pressure; the lower the water pressure, the greater the distance the two sets of driving components move the sliding rods apart, the wider the elastic baffle extends, the more micro-spray holes are blocked, and the more significant the water pressure compensation effect, thus maintaining the preset irrigation range.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0044] The present invention provides an intelligent water-saving irrigation device for landscaping maintenance, which will be described below with reference to Figures 1-12.

[0045] An intelligent water-saving irrigation device for landscaping maintenance, suitable for irrigating garden plants, includes two parallel water pipes 100. Multiple micro-sprinklers 200 are arranged between the two parallel water pipes 100, and are parallel to and perpendicular to the two parallel water pipes 100. Multiple micro-sprinkler holes 210 are evenly distributed on the outer periphery of each micro-sprinkler 200, both axially and circumferentially, to achieve precise spraying and avoid localized over-irrigation and water waste. The two parallel water pipes 100 are mounted on the ground 120, and [the device is described in the original text, but the translation is incomplete]. A water storage tank 110 is filled with water to be irrigated. The water storage tank 110 is connected to one end of two parallel water supply pipes 100, and a water pump (not shown in the figure) is installed at one end of the connection. The water pump pumps the water in the water storage tank 110 into the water supply pipes 100. The water has a certain pressure in the water supply pipes 100, so it can be sprayed out through the micro-spray holes 210 on multiple micro-spray pipes 200. The multiple micro-spray holes 210 are evenly distributed. Under constant water pressure, the area that the multiple micro-spray holes 210 can cover is also constant, which can irrigate garden plants evenly and reduce water waste caused by uneven irrigation.

[0046] However, existing irrigation devices cannot completely guarantee a constant water pressure from the pump, and the water pressure delivered by the pump may decrease. In this case, the water pressure inside the multiple micro-sprinklers 200 will decrease simultaneously, which will reduce the distance the water is sprayed from the micro-sprinkler holes 210, thereby reducing the irrigation range of the multiple micro-sprinklers 200 and creating obvious irrigation blind spots. Some plants will not receive water. If the water supply pressure is low for a long time, it will lead to uneven plant growth. In arid areas, plants are prone to wilting, yellowing leaves, and withering, which seriously affects the quality of landscaping. When faced with reduced water pressure, traditional devices often compensate for insufficient coverage by extending the irrigation time, which further wastes water resources.

[0047] Based on this, the present invention includes an adjustment component within multiple micro-sprinklers 200. This adjustment component is used to adjust the number of micro-sprinkler holes 210 that are open, and is configured to reduce the number of micro-sprinkler holes 210 that are open when the water pressure inside the water supply pipe 100 decreases. It is understood that, under constant water pressure, if more micro-sprinkler holes 210 on the micro-sprinkler pipe 200 are open, the water pressure from each individual micro-sprinkler hole 210 will decrease, resulting in a shorter spray distance. Conversely, if fewer micro-sprinkler holes 210 are open, the water pressure from each individual micro-sprinkler hole 210 will increase, thereby increasing the spray distance. Therefore, the present invention compensates for the reduction in irrigation area caused by decreased water pressure by reducing the number of open micro-sprinkler holes 210. This allows for maintaining a constant irrigation area as much as possible under reduced water pressure, ensuring more even irrigation of garden plants, improving water resource utilization, achieving intelligent water-saving effects, and preventing the impact of reduced water pressure on the greening quality of garden plants.

[0048] Specifically, the adjustment component in this embodiment includes a baffle plate 220 and a drive member 230. The baffle plate 220 is rotatably disposed inside the micro-spray tube 200. The baffle plate 220 is rectangular and has an arc to adapt to the arc-shaped surface of the inner circumference of the micro-spray tube 200. The water pressure inside the micro-spray tube 200 acts on the inner side of the baffle plate 220, so that the outer side of the baffle plate 220 can fit against the arc-shaped surface of the inner circumference of the micro-spray tube 200 to ensure that the micro-spray holes 210 are blocked. The length of the baffle plate 220 is similar to the length of the micro-spray tube 200. The baffle plate 220 can block multiple micro-spray holes 210 located at the same position in the axial direction of the micro-spray tube 200. The drive member 230 is used to drive the baffle plate 220 to rotate.

[0049] It should be noted that under normal water pressure, the baffle 220 does not block any micro-spray holes 210. When the water pressure decreases, the drive component 230 starts to drive the baffle 220 to rotate, so that the baffle 220 can block some of the micro-spray holes 210, thereby reducing the number of micro-spray holes 210 that are open. This increases the water pressure of the other micro-spray holes 210, thus maintaining the original irrigation area as much as possible, reducing irrigation blind spots, and improving the quality of garden plants. At the same time, the continuous rotation of the baffle 220 will not affect the overall irrigation area, ensuring that each area that needs water can be accurately replenished, avoiding repeated irrigation waste.

[0050] More specifically, the driving component 230 in this embodiment includes a driving motor 231, a rotating ring 232, and a magnet 233. The rotating ring 232 is rotatably sleeved on the outer periphery of the micro-nozzle 200, while the magnet 233 is fixedly mounted on the baffle plate 220. In this embodiment, the rotating ring 232 has magnetism at a certain position, so that the rotating ring 232 can attract the magnet 233 while rotating on the outer periphery of the micro-nozzle 200. In turn, the magnet 233 attracts the baffle plate 220 to rotate synchronously. The driving motor 231 is mounted on the ground 120. The driving motor 231 can drive the rotating ring 232 to rotate, thereby driving the baffle plate 220 to rotate synchronously.

[0051] It should be noted that, in order for the drive motor 231 to drive the baffles 220 inside multiple micro-nozzles 200 to rotate simultaneously, a belt or chain can be wound around the shaft of the drive motor 231, and the belt or chain can be wound around the outer circumference of multiple rotating rings 232 at the same time. When the drive motor 231 rotates, it can drive multiple rotating rings 232 to rotate synchronously. Two drive motors 231 can also be set up, and a pull rope 234 is wrapped around the outer circumference of multiple rotating rings 232. The pull rope 234 is wrapped around the outer circumference of each rotating ring 232 twice, and the two ends of the pull rope 234 are respectively connected to the rotating shafts of the two drive motors 231. When one drive motor 231 starts, the other drive motor 231 is turned off. The started drive motor 231 pulls the pull rope 234, which causes the pull rope 234 to pull the multiple rotating rings 232 to rotate synchronously. When the turned-off drive motor 231 starts, the other drive motor 231 is turned off, which pulls the multiple rotating rings 232 to rotate synchronously in the opposite direction. This ensures that the rotating rings 232 can drive the baffle plate 220 to rotate to block part of the micro-spraying holes 210, realize multi-pipe synchronous water-saving regulation, and avoid water waste.

[0052] In a further embodiment, the shield 220 in this embodiment is elastic, the width of the shield 220 can be increased, and the width of the shield 220 is negatively correlated with the water pressure inside the water pipe 100. That is, the lower the water pressure inside the water pipe 100, the wider the shield 220 will be, so as to block more micro-spray holes 210, thereby maximizing the irrigation range of the micro-spray pipe 200.

[0053] Specifically, the shielding plate 220 of this embodiment includes two parallel sliding rods 221 and an elastic baffle 222, as shown in Figures 8 and 9. The two parallel sliding rods 221 are rotatably connected inside the micro-spray nozzle 200. Specifically, the two parallel sliding rods 221 can revolve around the axis of the micro-spray nozzle 200. The elastic baffle 222 is fixedly connected to two parallel sliding rods 221 on both sides. The elastic baffle 222 is elastic. When the two parallel sliding rods 221 move away from each other, they can pull the elastic baffle 222 to extend, thereby increasing the overall width, so that the elastic baffle 222 can block more micro-spray nozzles 210.

[0054] More specifically, in this embodiment, to enable two parallel sliding rods 221 to be rotatably connected within the micro-nozzle 200, a connecting sleeve 240 is coaxially and fixedly installed inside the micro-nozzle 200. An arc-shaped slide rail 241 is provided on the connecting sleeve 240. The two parallel sliding rods 221 are slidably connected at both ends to the arc-shaped slide rails 241 of the connecting sleeves 240 at both ends of the micro-nozzle 200. Therefore, the two parallel sliding rods 221 can revolve around the axis of the micro-nozzle 200. To ensure that the two parallel sliding rods 221 only revolve along... The two parallel sliding rods 221, revolving around the axis of the micro-sprinkler 200 and slidingly sealing against the inner arc-shaped surface of the micro-sprinkler 200, are equipped with limiting rods 223 at both ends. The limiting rods 223 are also located within the arc-shaped slide rail 241. The limiting rods 223 ensure that the sliding rods 221 are always perpendicular to the arc-shaped slide rail 241, guaranteeing that the two sliding rods 221 remain parallel to each other as they revolve along the axis of the micro-sprinkler 200. Simultaneously, the elastic baffles 222 are perpendicular to both sides of the sliding rods 221 and slide in a sealed manner with the connecting sleeve 240. The two parallel sliding rods 221 drive the elastic baffles 222 to continuously block multiple micro-sprinkler holes 210, ensuring uniform blocking and preventing irrigation imbalance caused by prolonged closure of local micro-sprinkler holes 210, further improving the balance between water conservation and irrigation quality.

[0055] To facilitate the rotation of the two rotating rings 232 around the micro-spray nozzle 200, as shown in Figures 8 and 11, a first fixing sleeve 300 is provided on the two parallel water pipes 100 in this embodiment. One end of the first fixing sleeve 300 is fixedly connected to the side wall of the water pipe 100, and a second fixing sleeve 310 is fixedly connected to the other end of the first fixing sleeve 300. The second fixing sleeve 310 is bolted to a first threaded sleeve 320. The inner circumference of the first threaded sleeve 320 is coaxial and threadedly connected to a second threaded sleeve 330. The second threaded sleeve 330 is located away from the first threaded sleeve 320. One end of the threaded sleeve 320 is fixedly connected to the micro-nozzle 200, and the rotating ring 232 is rotatably connected to the outer circumference of the second threaded sleeve 330. The position of the magnet 233 inside the micro-nozzle 200 corresponds to the magnetic position on the rotating ring 232, so that when the rotating ring 232 rotates, it can drive the magnet 233 to rotate. The rotation of the magnet 233 in turn drives the two parallel sliding rods 221 to revolve around the axis of the micro-nozzle 200 in the arc-shaped slide rail 241. The elastic stop bar 222 between the two parallel sliding rods 221 rotates synchronously.

[0056] It should be noted that in this embodiment, the arc-shaped slide rail 241 is not completely connected. There is a blocking section 242 on the arc-shaped slide rail 241. The two parallel sliding rods 221 cannot pass through the blocking section 242. Furthermore, the micro-spray pipe 200 corresponding to the blocking section 242 is located in the area close to the ground 120. There are no micro-spray holes 210 in this area, so the two parallel sliding rods 221 do not need to pass through the blocking section 242. To ensure the continuous movement of the two parallel sliding rods 221, the two drive motors 231 in this embodiment are activated periodically. That is, when one drive motor 231 is activated, it drives the two parallel sliding rods 221 to the blocked section on the arc-shaped slide rail 241 via the rotating ring 232 and the magnet 233. At this point, the other drive motor 231 is activated, causing the two parallel sliding rods 221 to move in the opposite direction. When the two parallel sliding rods 221 move in the opposite direction and one of them contacts the blocked section on the arc-shaped slide rail 241, the drive motor 231 is turned off, and the other activated drive motor 231 is activated again, thereby changing the rotation direction of the two parallel sliding rods 221. This cycle continues until irrigation stops.

[0057] In a further embodiment, to increase the width of the baffle 220, the present invention provides two sets of driving members 230. The two sets of driving members 230 respectively drive the rotating rings 232 at both ends of the micro-spray nozzle 200. The rotating rings 232 rotate, causing the ends of two parallel sliding rods 221 to rotate simultaneously. When the water pressure inside the water pipe 100 has not decreased to a preset value (this preset value is set according to actual needs and is not specifically limited here), the two sets of driving members 230 work synchronously and rotate at the same speed, thereby causing the ends of the two parallel sliding rods 221 to rotate simultaneously. At this time, the distance between the two parallel sliding rods 221 remains constant. If the water pressure inside the water pipe 100... When the pressure drops to a preset value, the two sets of driving components 230 generate a speed difference, and the two rotating rings 232 begin to rotate relative to each other. The rotating ring 232 with a faster rotation speed drives one of the sliding rods 221 away from the other sliding rod 221 through the magnet 233, thereby increasing the distance between the two sliding rods 221 to pull the elastic baffle 222 to extend, which in turn increases the width of the baffle 220. The more the water pressure inside the water pipe 100 decreases, the greater the speed difference between the rotating rings 232 driven by the two sets of driving components 230, which in turn increases the distance between the two parallel sliding rods 221, and the wider the baffle 220, the more micro-spray holes 210 are blocked.

[0058] It should be noted that in this embodiment, the magnet 233 is located between two parallel sliding rods 221. The magnet 233 slides in contact with the elastic stop bar 222. In the initial state, the elastic stop bar 222 contracts, causing the two sliding rods 221 to abut against the two ends of the magnet 233. When the two rotating rings 232 generate a speed difference, the two rotating rings 232 exhibit relative displacement in the circumferential direction. That is, the magnet 233 driven by the two rotating rings 232 becomes misaligned, as shown in Figure 12. The two rotating rings 232 drive the two magnets 233 to exhibit relative displacement, and the rotation speed... The fast-rotating ring 232 drives the magnet 233 to move a considerable distance. One magnet 233 is located below and the other magnet 233 is located above. Since the two magnets 233 are located between two parallel sliding rods 221, the two magnets 233 will push the two parallel sliding rods 221 away from each other. This causes the two parallel sliding rods 221 to extend the elastic baffle 222 to increase the number of blocked micro-spray holes 210. Subsequently, the two sets of driving components 230 rotate at the same speed to maintain the distance between the two parallel sliding rods 221.

[0059] It should be noted that a pressure sensor (not shown in the figure) is installed inside the water supply pipe 100 in this embodiment. The pressure sensor is used to detect the water pressure inside the water supply pipe 100. When the water pressure decreases, a signal is sent to the two sets of drive motors 231. The two sets of drive motors 231 drive the rotating rings 232 at both ends of the micro-spray nozzle 200 to rotate synchronously, thereby driving the two parallel sliding rods 221 through the magnets 233, which in turn drive the elastic baffle 222 to block multiple micro-spray holes 210. When the water pressure is lower than the preset value, the data monitored by the pressure sensor will be transmitted to the control center (not shown in the figure). After analyzing the data, the control center controls the rotation speed of the two sets of drive motors 231 to have a rotational difference. When the two sets of drive motors 231 have a rotational speed difference, the rotating rings 232 will drive the two magnets 233 to generate a rotational speed difference, thereby causing the two magnets 233 to move relative to each other, as shown in Figure 12. This causes the two parallel sliding rods 221 to move away from each other, so that the elastic baffle 222 extends, thereby blocking more micro-spray holes 210.

[0060] If the water pressure drops significantly, the difference in rotational speed between the two sets of drive motors 231 will be greater, and the two parallel sliding rods 221 will move further apart, resulting in a greater increase in the width of the elastic baffle 222, which in turn blocks a larger number of micro-spray holes 210. Similarly, if the water pressure drops less, the difference in rotational speed between the two sets of drive motors 231 will be smaller, and the distance between the two parallel sliding rods 221 will be less, resulting in a smaller increase in the width of the elastic baffle 222, which in turn blocks a smaller number of micro-spray holes 210, thus maintaining the original irrigation area as much as possible under reduced water pressure.

[0061] The specific working process of the intelligent water-saving irrigation device for landscaping maintenance provided by the present invention will be described in conjunction with the above embodiments:

[0062] Start the water pump (not shown in the diagram):

[0063] The water pump inputs water from the water storage tank 110 into the water delivery pipe 100. The water in the water delivery pipe 100 flows through the micro-sprinkler pipe 200 and is finally sprayed out through multiple micro-sprinkler holes 210 on the micro-sprinkler pipe 200 to irrigate the garden plants.

[0064] Normal irrigation:

[0065] Under normal circumstances, the water pressure in the water supply pipe 100 is constant and maintained at the normal pressure value. At this time, the water is sprayed out through the micro-spray holes 210 on the micro-spray pipe 200 to irrigate the garden plants in the area.

[0066] Water pressure decreased:

[0067] If the pressure sensor in the water supply pipe 100 detects a decrease in water pressure, the two sets of drive motors 231 will start, thereby driving the rotating rings 232 at both ends of multiple micro-sprinklers 200 to rotate synchronously. The rotating rings 232 drive two parallel sliding rods 221 to revolve synchronously around the axis of the micro-sprinkler 200 through magnets 233. The elastic baffles 222 between the two parallel sliding rods 221 will be driven synchronously by the sliding rods 221, thereby blocking the same number of micro-sprinkler holes 210 in sequence. This reduces the number of micro-sprinkler holes 210 spraying water when the water pressure decreases, thus maintaining the outlet pressure of a single micro-sprinkler hole 210. This minimizes the impact of the decrease in water pressure in the water supply pipe 100 on the outlet pressure of a single micro-sprinkler hole 210, thereby maintaining the original irrigation area as much as possible and avoiding irrigation blind spots.

[0068] Water pressure is lower than preset value:

[0069] If the water pressure is lower than the preset value, the pressure sensor in the water supply pipe 100 will transmit the detected water pressure data to the control center (not shown in the figure). The control center analyzes the data. If the water pressure drops significantly, the speed difference between the two sets of drive motors 231 will increase, resulting in a larger speed difference between the two rotating rings 232 driven by the two sets of drive motors 231. Consequently, the two rotating rings 232 will move the two magnets 233 a greater distance relative to each other, and the two parallel sliding rods 221 will begin to move away from each other by a greater distance. This will cause the elastic stop bar 222 between the two parallel sliding rods 221 to extend to a larger extent. In other words, the elastic baffle 222 blocks more micro-spray nozzles 210, thereby compensating as much as possible for the reduction in irrigation area caused by a significant decrease in water pressure. If the water pressure decreases less, the speed difference between the two sets of drive motors 231 will decrease, resulting in a smaller speed difference between the two rotating rings 232 driven by the two sets of drive motors 231. Consequently, the distance that the two rotating rings 232 drive the two magnets 233 to move relative to each other is reduced, and the distance that the two parallel sliding rods 221 begin to move away from each other is smaller, resulting in a smaller extension area of ​​the elastic baffle 222 between the two parallel sliding rods 221. In other words, the number of micro-spray nozzles 210 blocked by the elastic baffle 222 is less than the number blocked when the extension area is larger, thereby compensating as much as possible for the reduction in irrigation area caused by a decrease in water pressure.

[0070] This invention also provides an intelligent water-saving irrigation method for garden greening maintenance, which requires the aforementioned intelligent water-saving irrigation device for garden greening maintenance, and includes the following steps:

[0071] Step S100: Start the water pump, which delivers water into two parallel water pipes 100. The water is then sprayed out through the micro-spray holes 210 on multiple micro-spray pipes 200 to irrigate the garden plants.

[0072] Step S200: If the water pressure in the water supply pipe 100 decreases, the adjusting component reduces the number of micro-sprinkler holes 210 that are opened to maintain the irrigation range of the multiple micro-sprinkler pipes 200.
