Description

Technical Field

[0001] This utility model relates to the field of garden irrigation technology, and more specifically, to an environmentally friendly garden water-saving irrigation device. Background Technology

[0002] In current garden maintenance, irrigation, as a crucial element for maintaining normal plant growth, is primarily implemented using timed controllers or manual operation. These traditional irrigation systems struggle to detect the actual water needs of plants in real time, leading to imprecise irrigation strategies and frequent problems of over-irrigation or under-irrigation. Over-irrigation not only wastes water resources but also easily causes soil compaction, nutrient loss, and root hypoxia; while under-irrigation affects plant growth and development, and in severe cases, can even lead to plant death, impacting the overall quality of the garden landscape.

[0003] Currently, most existing irrigation systems still rely on mains electricity or diesel power, resulting in high operating costs. Furthermore, laying power lines in remote areas or large-scale gardens involves significant engineering work and is difficult, hindering system deployment and subsequent maintenance. In addition, diesel pumps generate noise and harmful gas emissions during operation, increasing the carbon footprint and hindering environmental protection and the development of green horticulture. Moreover, traditional sprinkler irrigation equipment has an exposed structure, making it susceptible to environmental factors. For example, in dusty or windy areas, sprinkler heads are easily clogged by mud and sand, affecting spraying efficiency; prolonged exposure to rain and sun accelerates equipment aging and reduces system reliability. While some existing automated irrigation systems possess some timed control capabilities, they generally lack soil moisture monitoring and intelligent control functions based on moisture feedback, still requiring frequent manual intervention, limiting the level of automation and resource utilization efficiency.

[0004] Therefore, there is an urgent need to develop an intelligent irrigation system that combines environmental perception, energy independence, and sprinkler stability to improve the accuracy, economy, and green sustainability of garden irrigation. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the existing technology by proposing an environmentally friendly garden water-saving irrigation device, which aims to solve the problems of high energy consumption, poor environmental adaptability, and lack of intelligent control function based on soil moisture in existing irrigation systems, resulting in low automation, high maintenance costs, and insufficient resource utilization efficiency.

[0006] This utility model provides an environmentally friendly garden water-saving irrigation device, comprising: a sealed box and an installation pipe. The top of the sealed box is equipped with a solar energy storage mechanism, and the bottom of the sealed box is equipped with a control box. The installation pipe passes through the bottom of the control box and extends into the interior of the sealed box. The installation pipe is equipped with an external connecting pipe and a first electric valve, which is located inside the control box. A moisture detection mechanism is located on the outside of the control box. A cleaning mechanism is located between the top of the sealed box and the installation pipe. The inside of the control box is equipped with a telescopic mechanism and a controller. A lifting ring is located on the inner wall of the sealed box. A connecting plate is located between the lifting ring and the telescopic mechanism. A slot is formed on the outside of the sealed box. A lifting plate and a fixing plate are located on the slot. The lifting plate is mounted on the lifting ring. A nozzle is located on the fixing plate. A connecting pipe is located between the nozzle and the installation pipe. Multiple slots are arranged in a circular array.

[0007] Furthermore, the solar energy storage mechanism includes a solar panel and a battery, with the battery installed inside the sealed box and the solar panel installed on top of the sealed box.

[0008] Furthermore, the cleaning mechanism includes a cleaning pipe and a drive motor. The drive motor is installed inside the sealed box. The output end of the drive motor is provided with a water guide pipe that extends to the top of the sealed box. A cleaning brush is provided on one side of the water guide pipe. A water guide hole is provided between the cleaning brush and the water guide pipe. The cleaning pipe is installed on one side of the mounting pipe. A second electric valve is provided on the cleaning pipe. A telescopic hose is provided between one end of the cleaning pipe and the inside of the water guide pipe.

[0009] Furthermore, the water guide pipe at the output end of the drive motor is equipped with a rotary encoder that is linked to the cleaning brush.

[0010] Furthermore, the moisture detection mechanism includes a mounting cylinder and a telescopic rod. The mounting cylinder is installed on the outer wall of the control box. One end of the telescopic rod passes through one end of the mounting cylinder and is provided with a sealing sleeve. The other end of the telescopic rod is provided with a moisture detection probe. A transmission line is provided between the moisture detection probe and the controller.

[0011] Furthermore, the moisture detection mechanism is provided in multiple units and arranged in a ring array with the control box as the axis.

[0012] Furthermore, the telescopic mechanism is an electrically operated telescopic rod.

[0013] Furthermore, the drive motor is a servo motor.

[0014] Compared with existing technologies, the advantages of this invention are as follows: By setting up a solar energy storage mechanism, the irrigation system achieves energy self-sufficiency. The solar energy device not only provides electricity to the system, avoiding dependence on the traditional power grid, but also reduces carbon emissions, making it particularly suitable for remote or large-scale garden areas. It reduces the construction cost of power supply facilities and has excellent green environmental protection effects. Regarding the control system, the device integrates a controller and a first electric valve inside the control box, while a moisture detection mechanism is located on the outside.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] like Figures 1-5As shown in some embodiments of this application, an environmentally friendly garden water-saving irrigation device includes: a sealed box 1 and an installation pipe 2. The top of the sealed box 1 is provided with a solar energy storage mechanism, and the bottom of the sealed box 1 is provided with a control box 3. The installation pipe 2 passes through the bottom of the control box 3 and extends into the interior of the sealed box 1. The installation pipe 2 is provided with an external pipe 4 and a first electric valve 5. The first electric valve 5 is located inside the control box 3. The outside of the control box 3 is provided with a moisture detection mechanism. A cleaning mechanism is provided between the top of the sealed box 1 and the installation pipe 2. The inside of the control box 3 is provided with a telescopic mechanism 6 and a controller 7. The inner wall of the sealed box 1 is provided with a lifting ring 8. A connecting plate is provided between the lifting ring 8 and the telescopic mechanism 6. The outside of the sealed box 1 is provided with a slot. A lifting plate 9 and a fixing plate 10 are provided on the slot. The lifting plate 9 is installed on the lifting ring 8. A nozzle 11 is provided on the fixing plate 10. A connecting pipe 12 is provided between the nozzle 11 and the installation pipe 2. Multiple slots are provided and arranged in a circular array.

[0026] Understandably, the solar energy storage mechanism installed on top of the sealed box 1 provides green and renewable energy for the entire system. The solar panel 13 converts sunlight into electricity during the day, which is stored in the energy storage unit to power the control system, actuators such as electric valves and telescopic mechanisms 6, reducing reliance on traditional power sources and making it suitable for gardens, wastelands, and other scenarios lacking electricity access. Regarding water control, irrigation water is delivered via the installation pipe 2, which runs through the entire device structure and connects to the external pipe 4 and multiple sprinklers 11. The installation pipe 2 is equipped with a first electric valve 5, controlled by a controller 7. Based on soil moisture data provided by an external moisture detection device, the controller 7 determines whether irrigation is necessary. When dry soil is detected, the controller 7 issues a command to open the electric valve and initiate irrigation; once the soil moisture reaches the target level, the electric valve automatically closes, effectively preventing overwatering and achieving water-saving irrigation based on demand. For maintenance of the irrigation device, a cleaning mechanism is installed between the top of the sealed box 1 and the installation pipe 2, which can periodically flush or clean the water flow channel, preventing blockages in the pipes and sprinklers 11 due to sediment or impurities. This cleaning mechanism ensures the continuous water output of the sprinkler head 11, improves the stability and lifespan of the system, and reduces the burden of manual maintenance. The sprinkler head 11 system is arranged through multiple annular array slots on the outside of the sealed box 1. Each slot is equipped with a lifting plate 9 and a fixing plate 10, with the sprinkler head 11 fixed to the fixing plate 10. The lifting plate 9 is connected to an internal lifting ring 8, which in turn is connected to a telescopic mechanism 6 inside the control box 3. When the spray height needs to be adjusted, the controller 7 controls the telescopic mechanism 6 to drive the lifting ring 8 to move up and down, thereby raising and lowering the lifting plate 9 and the sprinkler head 11 as a whole. This structure allows the irrigation device to automatically adjust according to the different heights or growth stages of the plants, achieving precise irrigation and optimized water resource allocation.

[0027] It can be seen that the solar energy storage mechanism provides green energy, reduces energy consumption, and is suitable for use in areas without electricity, effectively improving the system's independence and environmental friendliness. The control box 3 integrates a moisture detection mechanism, a controller 7, and a first electric valve 5, enabling real-time monitoring of soil moisture and intelligent control of the irrigation process, significantly improving irrigation accuracy and water-saving effects. The cleaning mechanism prevents waterway blockage and ensures long-term stable operation of the system. The telescopic mechanism 6 drives the lifting ring 8 to lift and lower the nozzles 11, making the spraying height flexible and adjustable to meet the water requirements of different plants. The nozzles 11 are evenly distributed in a ring array, providing wide coverage and high irrigation efficiency. The overall structure is compact and highly integrated, offering multiple benefits such as energy saving, intelligence, high efficiency, and strong maintainability, making it suitable for the green irrigation needs of modern gardens.

[0028] Specifically, the solar energy storage mechanism includes a solar panel 13 and a battery 14. The battery 14 is installed inside the sealed box 1, and the solar panel 13 is installed on the top of the sealed box 1.

[0029] Understandably, by installing solar panels 13 on the top of the sealed box 1, the solar panels 13 convert light energy into electrical energy, which is then stored in the battery 14 installed inside the sealed box 1, thus providing continuous power to the irrigation device. This energy storage mechanism can effectively utilize renewable energy, ensure stable operation without external power, improve energy efficiency and self-powering capability, and thus support the normal operation of the irrigation controller 7 and related actuators.

[0030] Specifically, the cleaning mechanism includes a cleaning pipe 15 and a drive motor 16. The drive motor 16 is installed inside the sealed box 1. The output end of the drive motor 16 is provided with a water guide pipe that extends to the top of the sealed box 1. A cleaning brush 17 is provided on one side of the water guide pipe. A water guide hole is provided between the cleaning brush 17 and the water guide pipe. The cleaning pipe 15 is installed on one side of the mounting pipe 2. A second electric valve 18 is provided on the cleaning pipe 15. A telescopic hose 19 is provided between one end of the cleaning pipe 15 and the inside of the water guide pipe.

[0031] Specifically, the water guide pipe at the output end of the drive motor 16 is equipped with a rotary encoder that is linked to the cleaning brush 17.

[0032] Understandably, the drive motor 16 rotates the water guide pipe, thereby driving the cleaning brush 17 in conjunction with it. This causes the cleaning brush 17 to rotate and clean along the surface of the mounting pipe 2, while water is sprayed out through the water guide holes, working in conjunction with the cleaning brush 17 to rinse and clean the outer wall of the pipe or surrounding components. The water guide pipe is connected to the cleaning pipe 15 via a telescopic hose 19, allowing for extension and retraction at different locations, enhancing the flexibility of the cleaning range. A second electric valve 18 is installed on the cleaning pipe 15 to control the flow of cleaning water, enabling on-demand water supply. A matching rotary encoder monitors the rotation status of the cleaning brush 17, providing angle feedback or evaluating the cleaning effect, improving automation and operational reliability, and thus ensuring the long-term stable operation of the irrigation device and the smooth flow of water from the sprinkler head 11.

[0033] Specifically, the moisture detection mechanism includes an installation cylinder 20 and a telescopic rod 21. The installation cylinder 20 is installed on the outer wall of the control box 3. One end of the telescopic rod 21 passes through one end of the installation cylinder 20 and is provided with a sealing sleeve. The other end of the telescopic rod 21 is provided with a moisture detection probe 22. A transmission line is provided between the moisture detection probe 22 and the controller 7.

[0034] Understandably, by installing a mounting cylinder 20 on the outer wall of the control box 3, a stable installation and guiding structure is provided for the telescopic rod 21, allowing it to extend or retract flexibly. This adjusts the insertion depth of the moisture detection probe 22 into the soil, meeting the humidity monitoring needs of different plant root layers. The end of the telescopic rod 21 is equipped with a sealing sleeve, providing sealing protection and preventing the intrusion of external environmental factors such as moisture and dust into the internal mechanical structure and electrical connections, thus improving the durability of the probe and transmission line and the accuracy of measurements. The moisture detection probe 22, as the core sensing unit, directly contacts the soil to sense its moisture content. The signals it collects are transmitted to the controller 7 in real time via the transmission line. The controller 7 performs intelligent analysis and judgment based on this data, driving the electric valve and irrigation system to precisely switch on and off, ensuring that the irrigation process meets the actual water requirements of the plants, effectively avoiding over-irrigation or drought, and improving water resource utilization efficiency.

[0035] Preferably, the moisture detection mechanism has multiple units arranged in a ring array with the control box 3 as the axis.

[0036] Preferably, the telescopic mechanism 6 is an electric telescopic rod 21.

[0037] Preferably, the drive motor 16 is a servo motor.

[0038] It is understood that the environmentally friendly garden water-saving irrigation device in the above embodiments of this application converts solar energy into electrical energy and stores it in the internal battery 14 through a solar energy storage mechanism set at the top, ensuring that the system can continuously supply power without external power, thus improving the device's autonomous operation capability and environmental friendliness. Solar power not only reduces traditional electricity consumption but also facilitates installation in remote or power-free areas, meeting the green and energy-saving needs of garden irrigation. In terms of irrigation control, the device is equipped with a moisture detection mechanism, which consists of multiple sensor probes arranged in a ring around the outside of the control box 3. The probe depth can be flexibly adjusted by the telescopic rod 21 to achieve accurate moisture monitoring of different soil layers and plant root areas. The real-time soil moisture data collected by the probes is fed back to the controller 7 via a transmission line. The controller 7 intelligently determines whether to open the first electric valve 5 based on the soil moisture condition, accurately controlling the water flow to the installation pipe 2 and the nozzle 11 to achieve on-demand irrigation and effectively avoid water waste. To ensure the long-term stable operation of the system, a cleaning mechanism is provided on the top of the sealed box 1. The drive motor 16 rotates the water guide pipe and cleaning brush 17 via a rotary encoder. The cleaning brush 17, in conjunction with the sprayed water flow, periodically cleans the installation pipe 2 and the area around the nozzle 11, preventing mud and impurities from clogging the nozzle 11 or the pipes. A telescopic hose 19 connects the water guide pipe and the cleaning pipe 15, enhancing the flexibility and coverage of the cleaning mechanism, ensuring the irrigation equipment remains in good working order, and reducing maintenance costs. Finally, the nozzles 11 are mounted on a liftable lifting plate 9, which is partially distributed in multiple annular array slots on the outside of the sealed box 1. The lifting plate 9 is connected to a lifting ring 8 on the inner wall of the sealed box 1, and the lifting ring 8 is driven by an electric telescopic rod 21 inside the control box 3. The controller 7 can adjust the telescopic rod 21 to drive the lifting ring 8 according to the different growth heights and water requirements of the plants, thereby adjusting the spraying height of the nozzles 11 to achieve precise irrigation coverage and optimized water resource allocation.

[0039] The above embodiments describe an environmentally friendly garden water-saving irrigation device that achieves energy self-sufficiency through the installation of a solar energy storage mechanism. The solar energy device not only provides electricity to the system, avoiding dependence on the traditional power grid, but also reduces carbon emissions. It is particularly suitable for remote or large-scale garden areas, reducing the cost of power supply infrastructure construction and demonstrating excellent green environmental protection effects. Regarding the control system, the device integrates a controller 7 and a first electric valve 5 inside the control box 3, while also featuring a moisture detection mechanism on the outside. This mechanism monitors soil moisture in real time and automatically adjusts the irrigation switch, allowing for precise irrigation based on plant needs. This intelligent sensing and automatic adjustment mechanism effectively avoids water waste, improves irrigation efficiency and automation, and reduces the burden of manual management. Furthermore, the device includes a cleaning mechanism between the installation pipe 2 and the sealed box 1, which regularly cleans impurities from the inner wall of the pipe, preventing nozzle 11 blockage or uneven irrigation caused by impurity accumulation. This contributes to long-term stable system operation, extends service life, and reduces maintenance costs. The internal structure of the device also includes a telescopic mechanism 6 and a lifting ring 8. The height of the sprinkler head 11 is controlled by the linkage between the connecting plate and the lifting plate 9. In conjunction with multiple sprinkler heads 11 and connecting pipes 12 set in the slot of the sealed box 1, the height can be dynamically adjusted according to the water requirements or coverage height of the plants at different growth stages. The sprinkler heads 11 are arranged in a ring array, which provides a wide irrigation range and uniform water distribution, effectively avoiding problems such as missed irrigation and over-irrigation, and further improving the scientific nature and water-saving effect of irrigation.
