Description

Technical Field

[0001] This invention relates to the field of agricultural irrigation and water-saving equipment technology, and in particular to a lightweight, efficient, drought-resistant, and water-saving intelligent device. Background Technology

[0002] Water scarcity is one of the core challenges facing sustainable agricultural development globally. In particular, in arid and semi-arid regions, the contradiction between agricultural water supply and demand is prominent. Traditional irrigation methods (such as flood irrigation and furrow irrigation) have a water utilization rate of less than 40%, which not only causes serious water waste but also easily leads to secondary soil salinization and other problems, thus restricting the improvement of crop yield and quality.

[0003] To alleviate the above problems, existing technologies have developed water-saving irrigation equipment such as drip irrigation and sprinkler irrigation, but they still have many limitations: First, most of these devices are large and heavy, relying on fixed pipelines or large machinery for traction, resulting in poor mobility and making them difficult to adapt to complex terrains such as mountains and hills. Furthermore, their transportation and installation costs are high, making them unsuitable for small-scale planting. Second, the precision of irrigation pressure control is low. Existing equipment mostly uses a single pressure water supply mode, which cannot dynamically adjust the water supply pressure according to the water requirements of different crops and soil moisture conditions. This easily leads to localized over-irrigation (resulting in water waste) or under-irrigation (affecting drought resistance). Sudden pressure changes can also damage irrigation pipelines and shorten the equipment's lifespan. Third, there is a lack of effective water resource recycling mechanisms. When the water supply pressure is too high or when irrigation is not needed in certain areas, excess water is directly discharged into the environment and cannot be returned to the water supply system for secondary use, further exacerbating water resource consumption.

[0004] To address the aforementioned technical issues, this invention provides a lightweight, efficient, drought-resistant, and water-saving intelligent device. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-4 This invention provides a lightweight, high-efficiency drought-resistant and water-saving intelligent device, comprising: Base 1, a movable component is installed on the bottom surface of base 1, a support plate 2 is fixedly connected to the top surface of base 1, and a water supply tank 3 is installed on the top surface of base 1; Diversion box 4 is fixedly connected to support plate 2, and diversion box 4 is fixedly connected to water supply tank 3. Mounting frame 5 is fixedly connected to one side of support plate 2. Several mounting blocks 6 are mounted on the mounting frame 5. Air supply bridge pipe 7 is fixedly connected to the mounting block 6. One end of air supply bridge pipe 7 is fixedly connected to the diversion box 4. The other end of air supply bridge pipe 7 is detachably connected to the irrigation secondary pipe through a connector. The pressure regulating mechanism is provided in several groups, and the pressure regulating mechanism is respectively installed on the air supply bridge pipe 7. The pressure regulating mechanism is equipped with a return pipe 8, and the return pipe 8 is fixedly connected to the water supply tank 3. The distribution box 4 and the water supply box 3 are fixedly connected by a water supply pipe 9, and a first water pump 10 is installed on the water supply pipe 9; a second water pump 11 is installed on the return pipe 8.

[0023] After the equipment is started, the water in the water supply tank 3, driven by the first water pump 10, is stably transported through the water pipe 9 to the distribution box 4 fixed to the support plate 2. The distribution box 4 evenly distributes the water and then guides it into the air supply bridge pipes 7 fixed by several mounting blocks 6 on the mounting frame 5. Since the irrigation secondary pipe is detachably connected to the other end of the air supply bridge pipe 7 through the connector, the distributed water can be transported to the corresponding irrigation secondary pipe as needed to meet the irrigation needs of different areas. At the same time, each pressure regulating mechanism monitors the water supply pressure in the corresponding air supply bridge pipe 7 in real time. If the pressure is too high or needs to be adapted to the water demand pressure of different crops, the pressure regulating mechanism will dynamically adjust the pressure parameters. When there is excess water, the return pipe 8, under the action of the second water pump 11, returns the excess water to the water supply tank 3 for recycling. The whole process does not require a lot of manual intervention and can be flexibly adjusted according to soil moisture and crop water demand, always maintaining a stable and efficient water supply state, taking into account both drought resistance needs and water conservation goals.

[0024] The scheme is further optimized. The pressure regulating mechanism includes a pressure regulator body 12. The pressure regulator body 12 has an air inlet 13 and an air outlet 14 symmetrically opened on its side. The pressure regulator body 12 has a pressure relief port 15 opened at its bottom. A sealing component is slidably connected inside the pressure regulator body 12. The sealing component is set in correspondence with the air inlet 13, the air outlet 14 and the pressure relief port 15. An adjustment component is installed at the top of the pressure regulator body 12. The sealing component is rotatably connected to the adjustment component.

[0025] The adjusting head 22 is threadedly connected to the pressure regulator body 12. When the adjusting head 22 is rotated, the connecting rod 23 at its bottom moves up and down with the threaded movement. Because the connecting rod 23 is rotatably connected to the sleeve of the sealing assembly, it can push or pull the sealing block 16 to slide along the inner wall of the pressure regulator body 12, changing the relative position of the sealing block 16 and the sealing ring 17. The sealing ring 17 on the inner wall of the pressure regulator body 12 divides the cavity into upper and lower parts. The air inlet 13 (connected to the air supply bridge pipe 7) is located above the sealing ring 17, and the air outlet 14 (connected to the subsequent pipeline) is located below the sealing ring 17. When the sealing block 16 slides downward, the gap between the sealing block 16 and the sealing ring 17 decreases, the communication area between the air inlet 13 and the air outlet 14 decreases, the flow rate of the water / gas decreases, and the corresponding pipeline pressure decreases; conversely, when the sealing block 16 moves upward, the communication area increases, the pressure increases, and the basic pressure is adapted. A spring 21 is fitted onto the sliding rod 19 at the bottom of the sealing block 16. The spring 21 always pushes the sealing head 20 upwards, ensuring that the sealing head 20 fits tightly against the pressure relief port 15 (connected to the return pipe 8). Under normal conditions, the pressure relief port 15 is closed. When the pressure in the air supply bridge pipe 7 rises sharply and exceeds the elastic force of the spring 21, the pressure pushes the sealing head 20 downwards to compress the spring 21, opening the pressure relief port 15. Excess water / gas enters the return pipe 8 through the pressure relief port 15. Once the pressure drops to a safe value, the spring 21 resets and pushes the sealing head 20 to re-seal the pressure relief port 15, preventing excessive pressure from damaging the pipeline and simultaneously recovering excess resources. Sealing rings 24 are installed in the annular grooves on the outer walls of the sealing block 16 and the regulating head 22 to fill the gaps between components, preventing water / gas leakage from the connection points between the pressure regulator body 12 and the sealing block 16 and regulating head 22, ensuring pressure regulation accuracy and delivery efficiency.

[0026] Further optimization of the scheme: the sealing component includes a sealing block 16, a sealing ring 17 is fixedly connected to the inner wall of the pressure regulator body 12, the sealing ring 17 is sleeved on the outer wall of the sealing block 16, the air inlet 13 of the air inlet 13 and the air outlet 14 of the air outlet 14 are respectively located on the upper and lower sides of the sealing ring 17, a sliding hole 18 is opened at the bottom of the sealing block 16, a sliding rod 19 is slidably connected in the sliding hole 18, a sealing head 20 is fixedly connected to the bottom of the sliding rod 19, the sealing head 20 is correspondingly set with the pressure relief port 15, a spring 21 is sleeved on the sliding rod 19, the two ends of the spring 21 are fixedly connected to the sealing head 20 and the sealing block 16 respectively; a sleeve is fixedly connected to the top of the sealing head 20, and the adjusting component is rotatably connected to the sleeve.

[0027] Further optimization of the scheme: the adjustment component includes an adjustment head 22 threadedly connected to the top of the regulator body 12, and a connecting rod 23 fixedly connected to the bottom of the adjustment head 22, with the connecting rod 23 rotatably connected to the sleeve.

[0028] The scheme was further optimized by providing annular grooves on the outer wall of the sealing block 16 and the outer wall of the adjusting head 22, with sealing rings 24 installed in the annular grooves.

[0029] To further optimize the design, pressure sensors are installed at the ends of the air supply bridge pipe 7 and the return pipe 8, respectively, and the pressure sensors are electrically connected to an industrial control computer.

[0030] A pressure sensor at the end of the air supply bridge pipe 7 collects real-time water / gas pressure data within the pipe, while a pressure sensor at the end of the return pipe 8 synchronously monitors the return side pressure (reflecting pressure relief and circulation status). Both types of sensors transmit electrical signals to an industrial control computer, which compares the data using preset pressure thresholds (such as pressure ranges corresponding to the water requirements of different crops). If the pressure in the air supply bridge pipe 7 exceeds the threshold, the industrial control computer can trigger two control logics: first, it sends a signal prompting manual rotation of the regulating head 22 of the pressure regulating mechanism to reduce the air inlet-outlet connection area; second, it activates the second water pump 11 to increase its speed, enhancing the water recovery efficiency of the return pipe 8 and rapidly reducing the pressure on the air supply side. If the pressure is below the threshold, it reverses the control, achieving semi-automatic pressure adaptation without manual intervention, thus improving the accuracy and timeliness of drought-resistant water supply.

[0031] The scheme is further optimized. The connector includes an external threaded sleeve 25 fixedly connected to the end of the air supply bridge pipe 7, an internal threaded sleeve 26 rotatably connected to the end of the irrigation sub-pipe, the internal threaded sleeve 26 and the external threaded sleeve 25 are threadedly engaged, and sealing gaskets 27 are fixedly connected between the end of the air supply bridge pipe 7 and the end of the irrigation sub-pipe.

[0032] The connector achieves a convenient and reliable connection between the irrigation sub-pipe and the air supply bridge pipe 7 through "threaded fastening + leak-proof sealing": An external threaded sleeve 25 is fixed to the end of the air supply bridge pipe 7, and an internal threaded sleeve 26 is rotatably connected to the end of the irrigation sub-pipe (the internal threaded sleeve 26 can rotate relative to the pipe without causing the pipe to twist); when connecting, rotate the internal threaded sleeve 26 to make it engage with the external threaded sleeve 25. As the threads are tightened, the end of the irrigation sub-pipe gradually approaches the end of the air supply bridge pipe 7 until the sealing gaskets 27 of the two are tightly fitted. The threaded fit provides a stable axial tightening force, preventing loosening of the connection caused by pipeline pressure; the sealing gasket 27 fills the tiny gaps at the ends of the two pipes after being squeezed, preventing water / gas leakage, ensuring irrigation efficiency and avoiding water waste; the inner threaded sleeve 26 can be separated by rotating it in the opposite direction during disassembly, adapting to the pipeline combination requirements of different irrigation areas and improving the flexibility of equipment assembly.

[0033] Further optimization of the scheme: the two sides of the mounting block 6 are symmetrically fixedly connected with limit blocks 29. The cross-sectional shape of the limit block 29 is T-shaped. The mounting bracket 5 is provided with a limit groove. The shape of the limit groove is adapted to the shape of the limit block 29. The limit block 29 is slidably connected in the limit groove.

[0034] Further optimization of the design: the moving component includes several casters 28, which are symmetrically arranged on the bottom surface of the base 1.

[0035] The 28 omnidirectional wheels enable flexible equipment transport through a symmetrical layout and 360° turning. Several casters 28 are symmetrically distributed on the bottom surface of the base 1. The symmetrical layout can make the base 1 evenly stressed, avoiding tilting or jamming of the equipment due to the shift of the center of gravity. It is especially suitable for uneven terrain such as mountains and hills. The casters 28 can rotate 360° around a vertical axis. When pushing the equipment, the casters can automatically adjust the direction of travel, changing the position of the equipment without manual lifting, and easily transferring the equipment to different irrigation plots. Some casters 28 can be equipped with brakes (conventional auxiliary structure), which prevent the equipment from sliding due to terrain slope after being fixed, ensuring stability during irrigation, greatly reducing the labor cost of equipment transportation, and improving its applicability in complex terrain.
