Description

Technical Field

[0001] This invention relates to the field of constant pressure water supply equipment technology, specifically to a solar-based micro-irrigation constant pressure water supply equipment. Background Technology

[0002] Constant pressure water supply equipment is mainly used in hydraulic systems in fields such as construction, industry, and agriculture. It can ensure that the water pressure is always kept within a set stable pressure range under different water flow requirements in the system, thereby improving the efficiency and stability of the water supply system.

[0003] In constant pressure water supply equipment, stable water flow is one of the key technologies. When the pressure sensor fails, it cannot accurately detect the current water pressure, causing the control system to be unable to properly adjust the water pump operation, resulting in unstable water pressure and large fluctuations. In this situation, the control system may incorrectly start or stop the water pump, causing frequent start-stop cycles, which in turn affects the equipment's lifespan and system stability. Simultaneously, the control system cannot accurately adjust the water pump's operation to achieve the set target pressure, thus failing to meet the user's water pressure requirements. Inconsistent water pressures prevent the control system from promptly identifying abnormal conditions in the system, leading to either inadequate or excessive protection of the equipment, ultimately impacting stable operation and lifespan.

[0004] In industrial production, a certain water pressure is required to support equipment operation. Low water pressure can affect production efficiency, especially for factories that rely on water pressure for processing and manufacturing. Low water pressure can cause equipment to malfunction or even damage certain mechanical equipment, such as water pumps and pressure vessels. In addition, low water pressure can cause deposits to accumulate in pipes, leading to pipe blockage or internal corrosion and reducing pipe life.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs a solar-based micro-irrigation constant pressure water supply device, which solves the above technical problems. Summary of the Invention

[0006] The technical problem to be solved by this invention is that in industrial production, some equipment requires a specific water pressure to maintain stable operation. If the water pressure is unstable, the production efficiency will be affected, and the production process will be interrupted or slowed down. In addition, low water pressure will cause deposits to accumulate in the pipes, which will lead to pipe blockage or internal corrosion and reduce the life of the pipes.

[0007] To address the above problems, the present invention provides the following technical solution:

[0008] This invention provides a solar-powered micro-irrigation constant pressure water supply device, comprising a pressure tank, an inlet pipe, a control console, a water pump, and an outlet pipe. The inlet pipe is installed below the pressure tank, the control console is installed at the lower end of the inlet pipe, the water pump is installed at the lower end of the control console, and the outlet pipe is installed at the front end of the water pump. The device also includes an adjustment mechanism and a maintenance mechanism. The adjustment mechanism is installed inside the outlet pipe, and the maintenance mechanism is mounted on the adjustment mechanism. The adjustment mechanism uses liquid to push a flow divider cone backward, while the flow divider cone converts the horizontal displacement of the transmission rod into the rotation of a transmission gear. The maintenance mechanism uses gas to push adjusting blades, and the rotating adjusting blades adjust the rotation of the fixed cylinder in the adjustment mechanism by rotating the unfolding gear.

[0009] The regulating mechanism converts the horizontal displacement of the transmission rod into the rotation of the transmission gear by squeezing the diverting cone with liquid. The rotation of the regulating cylinder adjusts the position of the fixed cylinder, achieving precise water pressure regulation and ensuring a stable water supply to the micro-irrigation system. The regulating mechanism converts mechanical motion into the rotation of the transmission gear through liquid pressure, improving energy utilization efficiency and reducing energy waste. Furthermore, the precise adjustment of the regulating mechanism maintains a constant pressure water supply inside the outlet pipe, ensuring stable operation of the micro-irrigation system and avoiding the impact of pressure fluctuations on irrigation. The maintenance mechanism uses gas to drive the regulating blades, unfolding the gear rotation and adjusting the position of the fixed cylinder in the regulating mechanism, making the maintenance process more convenient while ensuring reliability and accuracy. When liquid flows in the pipe, the water flow squeezes the gas, driving the transmission blades in the maintenance mechanism to rotate. The rotation of the transmission blades drives the regulating cylinder in the regulating mechanism to rotate as well, opening the regulating plate. This better protects the regulating mechanism and prevents damage to parts caused by sudden liquid flow.

[0010] The adjusting mechanism includes a diverting cone, a transmission rod, a spiral block, a transmission gear, a spiral groove, a fixed cylinder, an adjusting spring, an adjusting cylinder, and a sealing ring. The diverting cone is installed inside the outlet pipe. A transmission rod is fixedly installed on the right side of the diverting cone, and a spiral block is installed at the other end of the transmission rod. A transmission gear is installed on the transmission rod, and a spiral groove is formed on the transmission gear. The spiral block slides within the spiral groove, and its position can be changed to adjust the rotation angle of the transmission gear. When the spiral block slides within the spiral groove, the movement is relatively smooth, avoiding sudden impacts or vibrations, which is beneficial to the stable operation of the system. By changing the position of the spiral block in the spiral groove, the rotation speed and direction of the transmission gear can be adjusted, thereby achieving flexible water supply adjustment of the micro-irrigation system to adapt to changes in demand under different scenarios. The sliding contact between the spiral block and the spiral groove reduces friction and wear, helping to extend the service life of the spiral block and spiral groove. A fixed cylinder is installed on the left side of the transmission rod, and an adjusting spring is engaged inside the fixed cylinder. The other end of the adjusting spring is engaged on the transmission rod. An adjusting cylinder is installed on the side of the transmission gear, and a sealing ring is installed on the adjusting cylinder.

[0011] The regulating mechanism achieves precise adjustment and control of water pressure through a liquid-squeezing diversion cone, ensuring constant pressure water supply and improving water flow control. The diversion cone also buffers fast-flowing liquids, preventing damage to components caused by excessively rapid liquid flow. The design of the transmission gear and spiral groove enables efficient energy transfer, converting the motion of the transmission rod into the rotation of the transmission gear, fully utilizing energy and improving energy transfer efficiency. The cooperation between the fixed cylinder and the regulating cylinder, along with the presence of the regulating spring, ensures the stability and reliability of the entire regulating mechanism, allowing it to maintain a stable working state during long-term use. This ensures that the system maintains constant pressure water supply with minimal energy consumption, contributing to energy conservation and reduced operating costs. The regulating mechanism can adapt to different irrigation needs and meet the constant pressure water supply requirements in various scenarios, improving the applicability and flexibility of the equipment.

[0012] The adjusting cylinder has a T-shaped cross-section. Gear teeth are installed on the outer surface of the T-shaped adjusting cylinder, meshing with peripheral gears to ensure stable power for the rotation of the rotating cylinder. The T-shaped adjusting cylinder's rotation on the limiting ring is also more stable, allowing the rotating cylinder to rotate smoothly and preventing collisions. It also provides stable support for the rotating cylinder. A limiting ring is installed on the adjusting cylinder, and rotating cylinders are arranged in an array on the limiting ring. A protective cover is installed inside the rotating cylinder. An adjusting plate is fixedly installed on the adjusting cylinder. The adjusting plate is fan-shaped, with its front center positioned on the adjusting cylinder.

[0013] The presence of a limit ring restricts the rotation angle of the T-shaped regulating cylinder, ensuring precise control during adjustment and preventing it from exceeding the set range. The gear teeth of the T-shaped regulating cylinder cooperate with the limit ring, allowing for more precise control of water flow direction and pressure during adjustment. By rotating the cylinder, the position of the limit ring can be changed, thereby affecting the rotation angle of the T-shaped regulating cylinder and adjusting the water flow direction and pressure. The cooperation between the limit ring and the rotating cylinder enables precise limiting of the regulating cylinder's rotation, ensuring that the water supply system can accurately adjust water flow and pressure as needed. The sector-shaped regulating plate, installed on the regulating cylinder, allows for fine-tuning of the pipe opening, facilitating precise adjustment and control of water flow and pressure. The sector-shaped regulating plate design allows for flexible adjustment of water flow, adapting to different working scenarios and irrigation needs, improving the system's adaptability and flexibility. A protective cover installed inside the regulating cylinder effectively protects it, preventing damage or impact on its function from external factors, enhancing the equipment's durability and reliability. The sector-shaped regulating plate, installed at the center of its front end, ensures the stability of the regulating plate, making it more stable when rotated by the cylinder, ensuring a secure and reliable adjustment and fixing process.

[0014] A gear groove is provided at the center of the rotating cylinder, and this groove is inclined. The convex brake block reduces direct friction between the brake block and the rotating cylinder, thereby reducing wear, extending the brake block's lifespan, and improving the system's durability. The inclined groove design prevents sudden jamming during braking, ensuring smooth braking and avoiding sudden system failures. The cooperation between the convex brake block and the inclined groove makes braking operation more convenient and ensures braking reliability. Simultaneously, the groove of the sealing ring is used to achieve a complete seal with the adjusting cylinder. The groove of the sealing ring has the same shape as the adjusting cylinder, ensuring the sealing degree of the adjusting mechanism, effectively preventing water leakage, guaranteeing the water sealing effect within the system, and improving the system's working efficiency and reliability.

[0015] The helical gear groove and the matching sealing ring achieve a good sealing effect, preventing water or other liquid leakage and ensuring a stable constant pressure water supply within the system. The sealing ring can withstand a certain pressure, preventing high-pressure liquid leakage and enhancing the system's pressure resistance and stability. The combined design of the sealing ring and helical gear groove ensures the reliability of the seal, avoiding system failure or malfunction due to leakage. The helical gear groove design reduces mechanical wear between the seal and the rotating cylinder, extending the service life of the seal and improving the system's reliability and durability. By maintaining good sealing, the equipment can maintain a constant pressure water supply more efficiently, improving the overall system's operating efficiency. The gear groove at the center of the rotating cylinder, through accurate braking, can avoid safety hazards caused by sudden stops or unstable operation of the equipment, ensuring the safe operation of the system. The gear groove, combined with the movement of the brake block, enhances the stability of the regulating cylinder. The regulating cylinder is cylindrical in shape; during rotation, the brake block applies a restrictive effect to the helical groove, better adjusting the regulating plate and making the regulating cylinder rotate more smoothly, improving the equipment's reliability and accuracy.

[0016] A brake block is fixedly installed at the upper end of the adjusting cylinder to restrict the rotation of the rotating cylinder. The brake block has a convex cross-sectional shape, and its size is similar to that of the gear groove in the rotating cylinder. This similarity in size provides a smooth braking effect. This avoids sudden braking impacts, ensures the smoothness of the equipment's braking process, and is beneficial to the stable operation of the equipment and system. Furthermore, the similarity in size between the brake block and the gear groove ensures even wear, extending the service life of the brake block.

[0017] The convex cross-sectional shape of the brake block helps ensure the stable fixation of the regulating cylinder, preventing accidental slippage or loosening during adjustment and maintaining a constant pressure water supply in the system. The convex shape of the brake block and the inclined groove of the rotating cylinder effectively prevent unnecessary adjustments or changes, ensuring normal equipment operation and preventing problems caused by improper adjustment. Simultaneously, the convex shape of the brake block can fit into the inclined spiral groove in the rotating cylinder, limiting rotation and making the rotation of the rotating cylinder more precise. When the convex shape of the brake block contacts the inclined spiral groove inside the rotating cylinder during rotation, it reduces friction, ensuring smooth rotation of the rotating cylinder and preventing sudden jamming. The special convex cross-sectional shape of the brake block allows the regulating cylinder to be fixed more precisely when needed, enhancing the accuracy and precision of adjustment. The fixed installation of the brake block facilitates better inspection and maintenance by maintenance personnel, improving maintenance efficiency and convenience. The presence of the brake block ensures that the regulating cylinder is firmly fixed after adjustment, enhancing the overall stability of the equipment and ensuring long-term stable operation of the system.

[0018] The size of the protective cover is the same as the groove on the transmission cylinder, and the central groove of the protective cover is convex. A limit ring is fixedly installed inside the convex groove of the protective cover. The convex groove helps to ensure the stable connection between the adjusting cylinder and the limit ring, providing a reliable protection mechanism for the entire system and preventing loosening or failure during use. At the same time, the adjusting cylinder is slidably installed in the convex groove of the protective cover. The convex shape of the central groove of the protective cover can limit and fix the adjusting cylinder and the limit ring, ensuring that the T-shaped adjusting cylinder moves stably within a specific range and preventing the T-shaped adjusting cylinder from directly contacting the rotating cylinder during rotation. This avoids the convex brake block on the adjusting cylinder from directly colliding with the side wall groove of the rotating cylinder, causing damage and rendering it unusable.

[0019] The outer diameter of the protective cover is equal to the inner diameter of the regulating cylinder, providing comprehensive protection for the cylinder and ensuring it is not damaged by external forces, thus enhancing the durability and stability of the equipment. The optimized design of the protective cover and its components improves the system's protection mechanism, ensuring stability and reliability during long-term operation and reducing the equipment's failure rate. Furthermore, the optimized design simplifies maintenance, reduces the difficulty of upkeep, and improves the maintainability and operability of the equipment.

[0020] The maintenance mechanism includes an unfolding gear, a transmission rod, transmission blades, a transmission cylinder, and adjusting blades. The unfolding gear is mounted on the side of the adjusting cylinder, and a connecting rod is installed at the center of the unfolding gear. A transmission blade is fixedly mounted at the front end of the connecting rod, and the transmission cylinder is slidably mounted on the side of the connecting rod. An adjusting blade is mounted at the front end of the transmission cylinder. The adjusting blade and the transmission blade can perform coaxial reverse rotation. This coaxial reverse rotation allows the adjusting blade and the transmission blade to move relative to each other on the same axis, providing precise control and adjustment capabilities. Through the coaxial reverse rotation of the adjusting blade and the transmission blade, the adjusting blade can rotate the T-shaped adjusting cylinder, unfolding the opening of the adjusting plate. Simultaneously, the rotating blade follows the adjusting blade in the opposite direction, closing the opening of the transmission cylinder. The coaxial reverse rotation reduces the resistance of the adjusting blade and the transmission blade, allowing them to move normally. The adjusting blade and the transmission blade can operate simultaneously without affecting their connection, enabling flexible adjustment of the maintenance state, adapting to different maintenance situations, and improving the flexibility and adaptability of the maintenance mechanism.

[0021] By employing coaxial reverse rotation, the system's stability during adjustment is maintained, preventing instability caused by abrupt changes and improving system reliability. This avoids complex non-coaxial structural designs, simplifying system design and maintenance, and reducing maintenance costs and technical complexity. The transmission cylinder design allows the transmission blades and adjusting blades to rotate coaxially in reverse, enabling multi-level maintenance functions, adapting to different maintenance needs, and enhancing the equipment's maintainability.

[0022] A limiting rod is installed at the front end of the connecting rod. The diameter of the limiting rod is equal to the inner diameter of the transmission cylinder, and the diameter of the limiting rod is greater than that of the connecting rod. At the same time, a limiting gear is fixedly installed on the transmission cylinder at the junction of the limiting rod and the connecting rod. The teeth on the limiting gear are inclined, and the inclination angle of the limiting gear can be adjusted, allowing adjustment of the limiting position of the limiting rod. This increases the flexibility and adaptability of the system. It can also provide rotational force to the transmission cylinder in one direction, preventing the transmission cylinder from being squeezed and damaged due to the reverse force of the adjusting cylinder, thus achieving a force relief. Two limiting blocks are installed on the side of the limiting rod near the connecting rod. A sliding block is slidably installed between the two limiting blocks, and a compression spring is engaged at the lower end of the sliding block.

[0023] The diameter of the limit rod is equal to the inner diameter of the transmission cylinder, ensuring the precision and accuracy of the limit. The inclined teeth of the limit gear enable more precise positional restriction. Through the coordinated action of the limit rod, limit gear, limit block, and sliding block, reliable limit of the transmission cylinder is achieved, preventing movement beyond the design range. Precise limit control ensures the transmission cylinder moves within a safe range, preventing dangerous situations or instability caused by exceeding safety limits. The compression spring at the lower end of the sliding block enables automatic reset of the limit rod, ensuring the system quickly returns to its initial state. The inclined angle of the limit gear is adjustable, allowing for adjustment of the limit rod's position, increasing the system's flexibility and adaptability. The use of suitable materials and design ensures the limit rod, limit gear, and related components have good wear resistance and durability, extending the system's service life. The compact design occupies little space, helping to simplify the overall structure, reduce system size, and improve system efficiency and performance.

[0024] The design of limit gears, limit blocks, and sliding blocks achieves precise transmission rod limiting, ensuring accuracy and stability during adjustment and maintenance. The presence of a compression spring enhances the safety of the limit function, ensuring the reliability of the limiting process and reducing the possibility of unexpected situations. The limit function and compression spring design simplify adjustment and maintenance, improve equipment operability, and reduce maintenance difficulty. The precise limit function and stable transmission mechanism together enhance system stability, ensuring the reliability of the equipment during long-term operation.

[0025] The teeth at the upper end of the sliding block face in the opposite direction to the teeth on the limiting gear. This opposite tooth direction and mutual engagement ensures a more stable interaction between the two during the limiting process, helping to prevent unnecessary vibration and loosening, and improving system stability. The reverse engagement results in a smooth limiting process, reducing impact and noise during limiting, protecting system components from excessive force and stress, and helping to extend the service life of system components. Furthermore, the mutual engagement between the teeth at the upper end of the sliding block and the teeth on the limiting gear, with the reverse engagement, can distribute wear during limiting, reducing wear at specific points, thereby extending the system's service life and maintenance cycle.

[0026] The opposite direction and mutual engagement of the gear teeth ensure more stable interaction during the limiting process, helping to prevent unnecessary vibration and loosening, and improving system stability. The reverse engagement results in a smooth limiting process, reducing impact and noise during limiting, protecting system components from excessive force and stress, and helping to extend the service life of system components. The reverse engagement can distribute wear during limiting, reducing wear at specific points, thereby extending the system's service life and maintenance cycle. The reverse engagement between the gear teeth provides more precise limit control, ensuring the system stops at the correct position, increasing system reliability and accuracy. The reverse engagement effectively prevents errors from escalating during limiting, ensuring accuracy, especially in applications requiring high precision. A smooth limiting process and accurate limit control help improve system efficiency, reduce energy consumption, and minimize unnecessary time waste.

[0027] The design of the upper teeth of the sliding block facing opposite directions to the teeth on the limit gear achieves precise limiting, ensuring accurate positioning and stability during equipment operation. The obtuse-angled triangular block on the sliding block, in conjunction with the limit gear, allows for more stable adjustment and rotation of the fixed cylinder. The sliding block's design transfers kinetic energy to the rotating cylinder, causing it to rotate in the opposite direction, thus unfolding the baffle and preparing for the next operation. The opposite direction of the upper teeth of the sliding block to the teeth on the limit gear reduces wear and friction, extending the equipment's service life.

[0028] The front end of the rotating cylinder has an arc-shaped groove, and a limit plate is installed at the front end of the rotating cylinder. A limit cylinder is fixedly installed on the limit plate, and the limit cylinder slides within the arc-shaped groove on the rotating cylinder. The combination of the arc-shaped groove and the limit cylinder provides a stable positioning function, preventing the rotating cylinder from moving unexpectedly when not needed. A tension cylinder is fixedly installed on the rotating cylinder, and a tension rod is rotatably installed on the tension cylinder. The other end of the tension rod is installed on a wind deflector plate. The wind deflector plate is petal-shaped. The petal-shaped wind deflector plate design can achieve a more precise sealing and windproof function. Furthermore, the two corner installation designs of the petal-shaped wind deflector plate can provide a more stable function for the rotation of the wind deflector plate, preventing other parts from colliding during rotation and causing damage to the parts. The four wind deflector plates are combined to form a circle, and a rotating rod is rotatably installed at the other corner of the wind deflector plate.

[0029] The position of the wind deflector can be easily adjusted and changed by rotating the rod, achieving flexible wind direction adjustment to meet the needs of different working conditions. The connection between the tension rod and the wind deflector is ensured by a limiting rod and a tension cylinder, guaranteeing the stability and reliability of the wind deflector and improving the system's operability. Rotating the wind deflector allows adjustment of the petal-shaped opening and closing degree. The combination of the limiting cylinder, fixed cylinder, and rotating rod, along with the design of the wind deflector, ensures stable rotation of the rotating cylinder, avoiding unnecessary swaying and shaking, and ensuring the normal operation of the equipment. The design of the rotating rod and adjusting rod makes wind direction adjustment simpler while ensuring the reliability of the adjustment process and reducing the possibility of errors. The petal-shaped wind deflector and the design of four pieces forming a circle minimize wind interference with irrigation, improving irrigation accuracy. The wind deflector's flexible rotation...

[0031] 1. This invention designs an adjustment mechanism that can achieve precise control of water pressure by rotating the adjustment cylinder, ensuring that the adjustment is made within the required water pressure range to meet specific process or usage requirements. At the same time, the adjustment mechanism can stabilize water pressure, prevent drastic fluctuations, and ensure that the system maintains a certain water pressure, which is beneficial to the stable operation of equipment and processes. Furthermore, the adjustment mechanism can achieve rapid response, quickly adjust water pressure to adapt to changing working conditions, and maintain water pressure stability.

[0032] 2. This invention utilizes a regulating cylinder to precisely regulate water pressure by adjusting the position of the diversion cone, ensuring constant water pressure supply. This allows the micro-irrigation system to supply water on demand, improving irrigation accuracy.

[0045] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0046] like Figure 1 and 2 As shown, the present invention provides a solar-based micro-irrigation constant pressure water supply device, including a pressure tank 1, an inlet pipe 2, a control console 3, a water pump 4, and an outlet pipe 5. The inlet pipe 2 is installed below the pressure tank 1, the control console 3 is installed at the lower end of the inlet pipe 2, the water pump 4 is installed at the lower end of the control console 3, and the outlet pipe 5 is installed at the front end of the water pump 4. It also includes an adjustment mechanism 6 and a maintenance mechanism 7. The adjustment mechanism 6 is installed inside the outlet pipe 5, and the maintenance mechanism 7 is installed on the adjustment mechanism 6. The adjustment mechanism 6 converts the horizontal displacement of the transmission rod 62 into the rotation of the transmission gear 64 by squeezing the flow divider cone 61 with liquid. The rotating transmission gear 64 then adjusts the rotation of the fixed cylinder 66 by rotating the adjustment cylinder 68. The maintenance mechanism 7 pushes the adjustment blade 75 with gas, and the rotating adjustment blade 75 adjusts the rotation of the fixed cylinder 66 in the adjustment mechanism 6 by rotating the unfolding gear 71.

[0047] The regulating mechanism 6 converts the horizontal displacement of the transmission rod 62 into the rotation of the transmission gear 64 by squeezing the diversion cone 61 with liquid. The rotation of the regulating cylinder 68 adjusts the position of the fixed cylinder 66, achieving precise water pressure regulation and ensuring stable water supply to the micro-irrigation system. The regulating mechanism 6 achieves energy conversion through liquid pressure, transforming mechanical motion into the rotation of the transmission gear 64, improving energy utilization efficiency and reducing energy waste. Furthermore, the precise adjustment of the regulating mechanism 6 maintains constant pressure water supply inside the outlet pipe 5, ensuring stable operation of the micro-irrigation system and avoiding the impact of pressure fluctuations on irrigation. The maintenance mechanism 7 uses gas to drive the regulating blade 75, unfolding the rotation of the gear 71 and adjusting the position of the fixed cylinder 66 in the regulating mechanism 6, making the maintenance process more convenient while ensuring reliability and accuracy. When liquid flows in the pipe, the water flow squeezes the gas, driving the transmission blade 73 in the maintenance mechanism 7 to rotate. The rotation of the transmission blade 73 drives the regulating cylinder 68 in the regulating mechanism 6 to rotate as well, opening the regulating plate 684, which better protects the regulating mechanism 6 and prevents damage to parts due to sudden liquid flow.

[0048] like Figure 2 , 3 As shown in Figure 4, the adjusting mechanism 6 includes a diverting cone 61, a transmission rod 62, a spiral block 63, a transmission gear 64, a spiral groove 65, a fixed cylinder 66, an adjusting spring 67, an adjusting cylinder 68, and a sealing ring 69. The diverting cone 61 is installed inside the outlet pipe 5. The transmission rod 62 is fixedly installed on the right side of the diverting cone 61. The spiral block 63 is installed at the other end of the transmission rod 62. The transmission gear 64 is installed on the transmission rod 62. The transmission gear 64 has a spiral groove 65. The spiral block 63 slides in the spiral groove 65. The rotation angle of the transmission gear 64 can be adjusted by changing its position. When the spiral block 63 slides in the spiral groove 65, the movement is relatively smooth, avoiding sudden impacts or vibrations, which is beneficial to the stable operation of the system. By changing the position of the spiral block 63 in the spiral groove 65, the rotation speed and direction of the transmission gear 64 can be adjusted, thereby realizing flexible water supply adjustment of the micro-irrigation system to adapt to changes in needs under different scenarios. The sliding contact between the spiral block 63 and the spiral groove 65 can reduce friction and wear, thus helping to extend the service life of the spiral block 63 and the spiral groove 65. A fixed cylinder 66 is installed on the left side of the transmission rod 62, and an adjusting spring 67 is snapped into the fixed cylinder 66. The other end of the adjusting spring 67 is snapped into the transmission rod 62. An adjusting cylinder 68 is installed on the side of the transmission gear 64, and a sealing ring 69 is installed on the adjusting cylinder 68.

[0049] When the liquid flows, the regulating mechanism 6 precisely regulates and controls the water pressure through the liquid-squeezing diversion cone 61, ensuring constant pressure water supply and improving the control of water flow. The diversion cone 61 can buffer fast-flowing liquids, preventing damage to parts caused by excessively rapid liquid flow. The design of the transmission gear 64 and spiral groove 65 achieves efficient energy transfer, converting the motion of the transmission rod 62 into the rotation of the transmission gear 64, making full use of energy and improving energy transfer efficiency. The cooperation between the fixed cylinder 66 and the regulating cylinder 68, as well as the presence of the regulating spring 67, ensures the stability and reliability of the entire regulating mechanism 6, enabling it to maintain a stable working state during long-term use. This ensures that the system maintains constant pressure water supply with minimal energy consumption, helping to save energy and reduce operating costs. The regulating mechanism 6 can adapt to different irrigation needs and meet the constant pressure water supply requirements in different scenarios, improving the applicability and flexibility of the equipment.

[0050] like Figure 3 , 4 As shown in Figure 5, the cross-sectional shape of the adjusting cylinder 68 is T-shaped, and gear teeth are installed on the outer side of the T-shaped adjusting cylinder 68. A limit ring 681 is installed on the adjusting cylinder 68, and adjusting cylinders 68 are arranged in an array on the limit ring 681. A protective cover 683 is installed inside the adjusting cylinder 68. An adjusting plate 684 is fixedly installed on the adjusting cylinder 68. The adjusting plate 684 is fan-shaped, and the center of the front end of the adjusting plate 684 is installed on the adjusting cylinder 68.

[0051] When the regulating cylinder 68 rotates, the limiting ring 681 restricts the rotation angle of the T-shaped regulating cylinder 68, ensuring precise control during the adjustment process and preventing it from exceeding the set range. The gear teeth of the T-shaped regulating cylinder 68 cooperate with the limiting ring 681, allowing for more precise control of the water flow direction and pressure during the adjustment process. By rotating the position of the cylinder 682, the position of the limiting ring 681 can be changed, thereby affecting the rotation angle of the T-shaped regulating cylinder 68 and adjusting the water flow direction and pressure. The cooperation between the limiting ring 681 and the rotating cylinder 682 can achieve precise limiting of the rotation of the regulating cylinder 68, ensuring that the water supply system can accurately adjust the water flow and pressure as needed. The sector-shaped regulating plate 684, by its position installed on the regulating cylinder 68, allows for fine-tuning of the pipe opening, which helps to precisely adjust and control the water flow and pressure. The design of the sector-shaped regulating plate 684 allows for flexible adjustment of the water flow, adapting to different working scenarios and irrigation needs, improving the system's adaptability and flexibility. The protective cover 683 is installed inside the adjusting cylinder 68, effectively protecting the adjusting cylinder 68 and preventing external factors from damaging or affecting its function, thus enhancing the durability and reliability of the equipment. The adjusting plate 684 is fan-shaped and is installed at the center of the front end of the adjusting plate 684, ensuring the stability of the adjusting plate 684 and making the adjusting plate 684 more stable when rotated by the rotating cylinder 682, ensuring that the adjustment and fixing process is firm and reliable.

[0052] like Figure 4 , 5 As shown in Figure 6, a gear groove is provided at the center of the rotating cylinder 682, and the gear groove on the rotating cylinder 682 is an oblique groove. At the same time, the groove of the sealing ring 69 is used to completely seal with the adjusting cylinder 68.

[0053] The helical gear groove and the matching sealing ring 69 achieve a good sealing effect, preventing water or other liquid leakage and ensuring a stable constant pressure water supply within the system. The sealing ring 69 can withstand a certain pressure, preventing high-pressure liquid leakage and enhancing the system's pressure resistance and stability. The combination design of the sealing ring 69 and the helical gear groove ensures the reliability of the seal, avoiding system failure or malfunction due to leakage. The helical gear groove design reduces mechanical wear between the seal and the rotating cylinder 682, extending the service life of the seal and improving the system's reliability and durability. By maintaining good sealing, the equipment can maintain a constant pressure water supply more efficiently, improving the overall system operating efficiency. The gear groove at the center of the rotating cylinder 682, through accurate braking, can avoid safety hazards caused by sudden stops or unstable operation of the equipment, ensuring the safe operation of the system. The movement of the gear groove combined with the brake block 685 enhances the stability of the adjusting cylinder 68. The adjusting cylinder 68 is cylindrical in shape. During rotation, the brake block 685 applies a restrictive effect to the spiral groove, which better adjusts the adjusting plate 684, making the adjusting cylinder 68 more stable during rotation and improving the reliability and accuracy of the equipment.

[0054] like Figure 4 and 5 As shown, a brake block 685 is fixedly installed at the upper end of the adjusting cylinder 68 to restrict the rotation of the rotating cylinder 682. The cross-sectional shape of the brake block 685 is convex, and the size of the brake block 685 is similar to the size of the gear groove in the rotating cylinder 682.

[0055] When the regulating cylinder 68 rotates, the convex cross-sectional shape of the brake block 685 helps ensure the stable fixation of the regulating cylinder 68, preventing accidental slippage or loosening during adjustment and ensuring a constant pressure water supply state for the system. The convex shape of the brake block 685 and the inclined groove of the rotating cylinder 682 effectively prevent unnecessary adjustments or changes, ensuring normal equipment operation and preventing problems caused by improper adjustment. Simultaneously, the convex shape of the brake block 685 can fit into the inclined spiral groove in the rotating cylinder 682, limiting rotation and making the rotation of the rotating cylinder 682 more precise. When the convex shape of the brake block 685 contacts the inclined spiral groove in the rotating cylinder 682 during rotation, it reduces friction, ensuring smooth rotation of the rotating cylinder 682 and preventing sudden jamming. The special convex cross-sectional shape of the brake block 685 allows the regulating cylinder 68 to be more precisely fixed when needed, enhancing the accuracy and precision of adjustment. The fixed installation of the brake block 685 helps maintenance personnel to better inspect and maintain the equipment, improving maintenance efficiency and convenience. The presence of the brake block 685 ensures that the adjusting cylinder 68 can be firmly fixed after adjustment, enhancing the overall stability of the equipment and ensuring the long-term stable operation of the system.

[0056] like Figure 6 As shown, the size of the protective cover 683 is the same as the groove on the transmission cylinder 74, and the central groove of the protective cover is convex. A limit ring 681 is fixedly installed inside the convex groove of the protective cover, and an adjusting cylinder 68 is slidably installed inside the convex groove of the protective cover.

[0057] When the regulating cylinder 68 rotates, the outer diameter of the protective cover 683 is equal to the inner diameter of the regulating cylinder 68, providing excellent protection for the regulating cylinder 68. This design ensures that the regulating cylinder 68 is protected from external damage, enhancing the durability and stability of the equipment. The convex shape of the central groove of the protective cover can limit and fix the regulating cylinder 68 and the limiting ring 681, ensuring that the T-shaped regulating cylinder 68 moves stably within a specific range and preventing the T-shaped regulating cylinder 68 from directly contacting the rotating cylinder 682 during rotation. This also prevents the convex brake block 685 on the regulating cylinder 68 from directly colliding with the side wall groove of the rotating cylinder 682, causing damage and rendering it unusable. The protective cover 683 improves the stability and accuracy of the system. The convex groove helps ensure a stable connection between the regulating cylinder 68 and the limiting ring 681, providing a reliable protection mechanism for the entire system and preventing loosening or failure during use. The design of the protective cover 683 and the protective cover optimizes the system's protection mechanism, ensuring the stability and reliability of the equipment during long-term operation and reducing the equipment's failure rate. The optimized protective cover 683 and its design make maintenance easier, reduce the difficulty of maintenance and upkeep, and improve the maintainability and operability of the equipment.

[0058] like Figure 2 , 6As shown in Figure 7, the maintenance mechanism 7 includes an unfolding gear 71, a transmission rod 62, a transmission blade 73, a transmission cylinder 74, and an adjusting blade 75. The unfolding gear 71 is mounted on the side of the adjusting cylinder 68. A connecting rod 72 is mounted at the center of the unfolding gear 71. The transmission blade 73 is fixedly mounted at the front end of the connecting rod 72. The transmission cylinder 74 is slidably mounted on the side of the connecting rod 72. The adjusting blade 75 is mounted at the front end of the transmission cylinder 74. The adjusting blade 75 and the transmission blade 73 can perform coaxial reverse rotation. This coaxial reverse rotation allows the adjusting blade 75 and the transmission blade 73 to move relative to each other on the same axis, providing precise control and adjustment capabilities. Through the coaxial reverse rotation of the adjusting blade 75 and the transmission blade 73, the adjusting blade 75 can rotate the T-shaped adjusting cylinder 68, unfolding the opening of the adjusting plate 684. Simultaneously, the rotating blade follows the adjusting blade 75 in the opposite direction, closing the opening of the transmission cylinder 74. The coaxial reverse rotation can reduce the resistance of the adjusting blade 75 and the transmission blade 73, allowing them to move normally. The adjusting blade 75 and the transmission blade 73 can be driven simultaneously without affecting the connection between them, enabling flexible adjustment of the maintenance status, adapting to different maintenance conditions, and improving the flexibility and adaptability of the maintenance mechanism 7.

[0059] When the blades rotate, the coaxial reverse motion maintains the stability of the system during adjustment, preventing instability caused by abrupt adjustments and improving system reliability. This avoids complex non-coaxial structural designs, simplifying system design and maintenance, and reducing maintenance costs and technical difficulty. The design of the transmission cylinder 74 allows the transmission blades 73 and the adjusting blades 75 to move in coaxial reverse directions, achieving multi-level maintenance functions, adapting to different maintenance needs, and enhancing the maintainability of the equipment.

[0060] like Figure 6 and 7 As shown, a limiting rod 721 is installed at the front end of the connecting rod 72. The diameter of the limiting rod 721 is equal to the inner diameter of the transmission cylinder 74, and the diameter of the limiting rod 721 is greater than the diameter of the connecting rod 72. At the same time, a limiting gear 722 is fixedly installed on the transmission cylinder 74 at the junction of the limiting rod 721 and the connecting rod 72. The teeth on the limiting gear 722 are inclined, and the inclination angle of the limiting gear 722 can be adjusted, allowing the limiting position of the limiting rod 721 to be adjusted, which increases the flexibility and adaptability of the system. At the same time, it can provide rotational force to the transmission cylinder in one direction, preventing the transmission cylinder 74 from being squeezed and damaged due to the reverse force of the adjusting cylinder 68, thus achieving a force relief. Two limiting blocks 723 are installed on the side of the limiting rod 721 near the connecting rod 72. A sliding block 724 is slidably installed between the two limiting blocks 723. A compression spring 725 is engaged at the lower end of the sliding block 724.

[0061] When the transmission cylinder 74 rotates, the diameter of the limiting rod 721 is equal to the inner diameter of the transmission cylinder 74, ensuring the precision and accuracy of the limiting position. The inclined teeth of the limiting gear 722 allow for more precise position restriction. Through the coordinated action of the limiting rod 721, the limiting gear 722, the limiting block 723, and the sliding block 724, reliable limiting of the transmission cylinder 74 is achieved, preventing movement beyond the design range. Precise limit control ensures that the transmission cylinder 74 moves within a safe range, preventing dangerous situations or instability caused by exceeding the safe range. The compression spring 725, engaged at the lower end of the sliding block 724, enables automatic reset of the limiting rod 721, ensuring the system quickly returns to its initial state. The adjustable inclination angle of the limiting gear 722 allows for adjustment of the limiting position of the limiting rod 721, increasing the system's flexibility and adaptability. The use of suitable materials and design ensures that the limiting rod 721, the limiting gear 722, and related components have good wear resistance and durability, extending the system's service life. Its compact design and small footprint help simplify the overall structure, reduce system size, and improve system efficiency and performance.

[0062] The design of the limiting gear 722, limiting block 723, and sliding block 724 achieves precise limiting of the transmission rod 62, ensuring accuracy and stability during adjustment and maintenance. The presence of the compression spring 725 enhances the safety of the limiting function, ensures the reliability of the limiting process, and reduces the possibility of unexpected situations. The design of the limiting function and the compression spring 725 simplifies adjustment and maintenance, improves the operability of the equipment, and reduces the difficulty of maintenance. The precise limiting function and stable transmission mechanism together enhance the stability of the system and ensure the reliability of the equipment during long-term operation.

[0063] like Figure 7 , 8 As shown in Figure 9, the teeth at the upper end of the sliding block 724 are in the opposite direction to the teeth on the limiting gear 722. This opposite tooth direction and mutual engagement makes the interaction between the two more stable during the limiting process, helping to prevent unnecessary vibration and loosening, and improving system stability. The reverse engagement results in a smooth limiting process, reducing impact and noise during limiting, protecting system components from excessive force and stress, and helping to extend the service life of system components. Furthermore, the mutual engagement between the teeth at the upper end of the sliding block 724 and the teeth on the limiting gear 722, with the reverse engagement, can distribute wear during limiting, reducing wear at specific points, thereby extending the system's service life and maintenance cycle.

[0064] When the adjusting cylinder 68 reverses, the gear teeth move in opposite directions and engage with each other, making the interaction between them more stable during the limiting process. This helps prevent unnecessary vibration and loosening, improving system stability. The reverse engagement results in a smooth limiting process, reducing impact and noise during limiting, protecting system components from excessive force and stress, and helping to extend the service life of system components. The reverse engagement can distribute wear during limiting, reducing wear at specific points, thereby extending the system's service life and maintenance cycle. The reverse engagement between the gear teeth provides more precise limit control, ensuring the system stops at the correct position, increasing system reliability and accuracy. The reverse engagement effectively prevents errors from escalating during limiting, ensuring limit accuracy, especially in applications requiring high precision. A smooth limiting process and accurate limit control help improve system efficiency, reduce energy consumption, and minimize unnecessary time waste.

[0065] like Figure 7 , 8 As shown in Figure 9, the front end of the rotating cylinder 76 has an arc-shaped groove 761, and a limiting plate 762 is installed at the front end of the rotating cylinder 76. A limiting cylinder 763 is fixedly installed on the limiting plate 762, and the limiting cylinder 763 slides within the arc-shaped groove 761 on the rotating cylinder 76. The combination of the arc-shaped groove 761 and the limiting cylinder 763 provides a stable positioning function, preventing the rotating cylinder 76 from moving unexpectedly when not needed. A tension cylinder 764 is fixedly installed on the rotating cylinder 76, and a tension rod 76 is rotatably installed on the tension cylinder 764. 5. The other end of the tension rod 765 is installed on the wind deflector 766. The wind deflector 766 is petal-shaped. The petal-shaped wind deflector 766 can achieve a more precise sealing and wind-blocking function. The two corner installation designs of the petal-shaped wind deflector 766 can provide a more stable function for the rotation of the wind deflector 766, preventing other parts from colliding during rotation and causing damage to the parts. The four wind deflectors 766 are combined to form a circle. A rotating rod 767 is rotatably installed at the other corner of the wind deflector 766.

[0066] When the rotating drum 76 rotates, the position of the wind deflector 766 can be easily adjusted and changed via the rotating rod 767, achieving flexible wind direction adjustment to meet the needs of different working conditions. The connection between the tension rod 765 and the wind deflector 766 is ensured by the limiting rod 721 and the tension cylinder 764, guaranteeing the stability and reliability of the wind deflector 766 and improving the operability of the system. By rotating the wind deflector 766, the opening and closing degree of the petal shape can be adjusted. The combination of the limiting cylinder 763, the fixed cylinder 66, and the rotating rod, as well as the design of the wind deflector 766, ensures the stable rotation of the rotating drum 76, avoiding unnecessary swaying and shaking, and ensuring the normal operation of the equipment. The design of the rotating rod and the adjusting rod makes wind direction adjustment simpler, while ensuring the reliability of the adjustment process and reducing the possibility of errors. The petal-shaped wind deflector 766 and the design of four pieces combined into a circle minimize wind interference with irrigation and improve irrigation accuracy. The flexible rotation of the wind deflector 766...
