Description

Technical Field

[0001] This invention relates to irrigation equipment technology, specifically to a water-saving intelligent irrigation device for gardens and its irrigation method. Background Technology

[0002] Gardens are popular recreational spaces in people's daily lives, filled with flowers, green grass, and large trees, making them ideal places to connect with nature. To ensure the healthy growth of plants within gardens, irrigation systems are installed around them to provide water and prevent them from withering due to lack of water. Gardens require regular watering of vegetation. Traditionally, fertilization was done manually before watering, which was not only time-consuming and labor-intensive but also physically demanding.

[0003] Chinese invention patent CN118216414A discloses a garden irrigation device. This device comprises a drive assembly, a transmission assembly, an irrigation pipe, and a soil-breaking ball. A servo motor drives a rotating base, which in turn controls the rotation of the irrigation pipe. This causes the irrigation pipe to pull the soil-breaking ball to extend to the roots of broadleaf shrubs. The soil-breaking ball breaks up and loosens the soil around the roots, while simultaneously delivering water directly to the soil, improving irrigation efficiency and preventing broadleaf shrubs from blocking water droplets from contacting the shrub roots. By incorporating the drive assembly and irrigation pipe, the servo motor is activated before the irrigation pipe rotates to encircle the shrub. The motor, a servo motor, drives the impeller to rotate. The rotation of the impeller can apply water pressure, allowing cold water to quickly enter the inside of the irrigation pipe and spray out through the spray holes. The high-pressure water jet can wash away dust from the surface of the broad leaves of the shrubs, preventing dust from affecting the photosynthesis of the broad leaves. By setting up a light-transmitting elastic membrane and irrigation pipe, the light-transmitting elastic membrane can wrap the shrubs, avoiding the impact of wind and sand on the shrubs. At the same time, the light-transmitting elastic membrane can block and retain water evaporation during the day. At night, the water vapor cools and liquefies, producing water droplets that slide down the curved surface of the light-transmitting elastic membrane to the guide folds. Under the guidance of the folds, the water flows back to the soil, prolonging the soil's moisture time.

[0004] When existing equipment is used in traditional garden irrigation systems, water pressure may fluctuate in different areas due to factors such as pipe length, equipment installation location, and water supply, resulting in uneven irrigation effects. At the same time, it cannot ensure that crops receive adequate water and nutrient delivery, which weakens or over-nourishes the nutrients required for crop growth and easily leads to excess water waste. Therefore, a water-saving intelligent irrigation device and irrigation method for gardens have been developed. Summary of the Invention

[0042] Example 1:

[0043] Please see Figures 1-9 A water-saving intelligent irrigation device for gardens includes a base 1, with a delivery pipe 11 at the end of the base 1, and an outlet pipe 12 connected to the outer surface of the delivery pipe 11.

[0044] In this scheme, external water is introduced into the delivery pipe 11 through the outlet pipe 12, thereby working with the push component 2 to push the water to the spraying part to irrigate the crops.

[0045] Furthermore, the push assembly 2, which is assembled on the inner wall of the base 1, pressurizes and delivers the water required for irrigation. The push assembly 2 includes a drive component 21 connected to the base 1. A crankshaft 22 is provided at the output end of the drive component 21. A push rod 23 is rotatably mounted on the outer surface of the crankshaft 22. A pressure block 24 is rotatably mounted on the end of the push rod 23 away from the crankshaft 22. The outer surface of the pressure block 24 is slidably connected to the inner wall of the delivery pipe 11.

[0046] In this embodiment, the drive unit 21 is a device with power output such as a motor, and is connected to an external control device. When the drive unit 21 is started, it synchronously drives the crankshaft 22 located at its output end to rotate.

[0047] When the crankshaft 22 rotates, it drives the push rod 23 on its outer surface to move. At the same time, the end of the push rod 23 is provided with a pressure block 24, so that when the crankshaft 22 rotates, it works with the push rod 23 to drive the pressure block 24 to move on the inner wall of the delivery pipe 11. The outer surface of the pressure block 24 is provided with rubber or other sealing components.

[0048] The outer surface of the conveying pipe 11 is provided with a vent hole, the inner wall of the vent hole is provided with a grid plate, and the inner cavity of the vent hole is provided with a rubber ball. When the pressure block 24 moves forward, the rubber ball is tightly attached to the inner wall of the vent hole to keep it sealed. When the pressure block 24 retracts backward, the rubber ball moves backward and fits with the grid plate, so that the conveying pipe 11 can communicate with the outside.

[0049] Furthermore, a support plate 25 is provided at the end of the pressure block 24. A through hole 251 is provided on one side of the support plate 25. The inner wall of the through hole 251 is slidably connected to the outer surface of the crankshaft 22. At the same time, a limit cylinder 252 is slidably installed on the outer surface of the support plate 25. The outer surface of the limit cylinder 252 is connected to the end of the base 1.

[0050] Specifically, the pressure block 24 is constrained by the support plate 25, thereby ensuring overall stability when the pressure block 24 moves. At the same time, the support plate 25 is constrained by the crankshaft 22 and the limiting cylinder 252, thus ensuring the stability of the support plate 25.

[0051] Furthermore, a movable rod 26 is rotatably mounted on the outer surface of the crankshaft 22 and on one side of the push rod 23. A transmission block 261 is rotatably mounted on the end of the movable rod 26 away from the crankshaft 22, and a movable block 262 is provided at the end of the transmission block 261.

[0052] Specifically, when the crankshaft 22 rotates, it synchronously drives the movable rod 26, which is rotatably mounted on its outer surface, to move. Since the end of the movable rod 26 is rotatably mounted with a transmission block 261, when the transmission block 261 moves, it synchronously drives the movable block 262 to move.

[0053] The transmission block 261 is composed of a positioning cylinder and a slider. The inner wall of the positioning cylinder is slidably connected to the outer surface of the slider. One end of the slider is connected to the movable rod 26, and the other end is connected to the movable block 262. The outer surface of the positioning cylinder is connected to the end of the base 1.

[0054] Furthermore, a ring 27 is provided on the inner wall of the conveying pipe 11 and at one end of the pressure block 24. A positioning block 28 is provided at the end of the ring 27. An elastic element 281 is provided on the inner wall of the positioning block 28. At the same time, a protective plate 282 is provided at the end of the elastic element 281. The outer surface of the protective plate 282 is in contact with the inner wall of the ring 27.

[0055] Specifically, the outer surface of the protective plate 282 is provided with sealing components such as rubber. By adhering the protective plate 282 to the inner wall of the ring 27, the two ends of the conveying pipe 11 are separated. At the same time, the elastic element 281 is a spring or other elastic component. The elastic element 281 supports the protective plate 282, so that the protective plate 282 is pressed tightly against the ring 27, ensuring the stability of the protective plate 282.

[0056] Furthermore, the regulating component 3, which is mounted on the inner wall of the outlet pipe 12, controls the amount of water required for irrigation. The regulating component 3 includes a rotating shaft 31 connected to the outlet pipe 12, with the end of the rotating shaft 31 penetrating and extending into the inner cavity of the outlet pipe 12. A turntable 32 is provided at the end of the rotating shaft 31. A telescopic rod 33 is provided at the end of the turntable 32 near its edge, and a collar 34 is provided at the end of the telescopic rod 33.

[0057] In this embodiment, when the rotating shaft 31 rotates, it synchronously drives the turntable 32 located at its end to rotate. At the same time, when the turntable 32 rotates, it drives the telescopic rod 33 located at the end of the turntable 32 to rotate. The telescopic rod 33 is composed of two sleeves, and the inner wall of one sleeve is slidably connected to the outer surface of the other sleeve, thereby ensuring that the turntable 32 rotates smoothly.

[0058] Furthermore, an adjusting shaft 35 is slidably mounted on the inner wall of the collar 34, and a fixing plate 351 is provided at both ends of the adjusting shaft 35. A movable shaft 36 is provided at the end of the fixing plate 351 away from the adjusting shaft 35, and an arc-shaped plate 38 is provided at both ends of the movable shaft 36.

[0059] Specifically, when the telescopic rod 33 moves in conjunction with the collar 34, it synchronously drives the adjusting shaft 35, which is slidably mounted on its end, to swing, and drives the fixed plates 351, which are set at both ends of the adjusting shaft 35, to move. Since the fixed plate 351 is provided with a movable shaft 36 at its end, the movable shaft 36 moves synchronously with the fixed plate 351, and drives the arc-shaped plates 38, which are set at both ends of the movable shaft 36, to rotate. The two arc-shaped plates 38 are distributed in an alternating manner.

[0060] Furthermore, the inner wall of the outlet tube 12 is provided with a snap-fit ​​block 37, the end of which is rotatably connected to the outer surface of the movable shaft 36. The inner wall of the outlet tube 12 is provided with a baffle 381, one side of which is in contact with the outer surface of the arc-shaped plate 38.

[0061] Specifically, the outer surface of the movable shaft 36 is limited by the snap-fit ​​block 37 so that no shaking occurs when the movable shaft 36 rotates. At the same time, the end of the baffle 381 has a slot, and both the outer surfaces of the baffle 381 and the arc plate 38 are provided with rubber or other sealing components, so that the arc plate 38 and the baffle 381 are sealed when they are in contact.

[0062] When the two arc-shaped plates 38 rotate, the upper end is in a closed state while the lower end is in a through state, and the upper end is in a through state while the lower end is in a closed state, thus enabling quantitative conveying.

[0063] Furthermore, a rotating cylinder 392 is provided at the end of the rotating shaft 31, and an arc-shaped groove 393 is formed on the outer surface of the rotating cylinder 392. A movable cylinder 39 is provided at the end of the movable block 262, and a protrusion 391 is provided on the inner wall of the movable cylinder 39 to fit against the inner wall of the arc-shaped groove 393. At the same time, the outer surface of the protrusion 391 is slidably connected to the inner wall of the arc-shaped groove 393.

[0064] Specifically, when the movable block 262 moves, it synchronously drives the movable cylinder 39 at its end to move. Since the inner wall of the movable cylinder 39 is provided with a protrusion 391, when the movable cylinder 39 moves, it cooperates with the protrusion 391 to push the rotating cylinder 392 to rotate. The end of the rotating cylinder 392 is connected to the rotating shaft 31, so that the rotating shaft 31 rotates synchronously with the rotating cylinder 392.

[0065] The control device can be a microcontroller. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantages are its small size, allowing it to be placed inside the instrument, but it has limited storage, simple input / output interfaces, and low power consumption.

[0066] Example 2:

[0067] A water-saving intelligent irrigation method for gardens includes the following steps:

[0068] S1. When the movable cylinder 39 moves, the protrusion 391 pushes the rotating cylinder 392 to rotate, so that the rotating shaft 31 rotates synchronously with the rotating cylinder 392, and the movable shaft 36 drives the arc plate 38 to rotate.

[0069] S2. When the two arc plates 38 rotate, the upper end is in a closed state and the lower end is in a through state; when the upper end is in a through state and the lower end is in a closed state.

[0070] S3. When the crankshaft 22 rotates, it works with the push rod 23 to drive the pressure block 24 to move, thereby pressurizing the water on the inner wall of the delivery pipe 11.

[0071] S4, baffle 381 and arc plate 38 isolate the water body to prevent water loss.

[0072] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
