Description

Technical Field

[0001] The present invention relates to the technical field of valves, in particular to a multi-position automatic sequence distribution valve device. Background Art

[0002] In the agricultural production system, paddy field irrigation is a key link in ensuring the healthy growth of crops and achieving high and stable yields. As an important control device in the irrigation system, the performance of irrigation valve devices directly determines the quality and efficiency of irrigation. Currently, most paddy field irrigation in my country still relies on traditional methods such as border irrigation, furrow irrigation, flooding irrigation, and canal irrigation. Under these traditional irrigation modes, water flow between ditches and fields is often regulated using primitive methods such as earth piling and sandbag barriers. These methods are not only extremely cumbersome and require huge manpower investment, but also lack precision in the irrigation process, which easily leads to serious waste of water resources and is difficult to adapt to the development needs of modern agriculture for efficient and water-saving development.

[0003] Common irrigation valves on the market, such as butterfly valves, ball valves, and gate valves, each have significant limitations. While butterfly valves can quickly regulate water flow in large-diameter agricultural irrigation pipes, facilitating system control and management, their complex structural design and manufacturing process lead to high costs. Ball valves are suitable for frequently opened and closed irrigation pipes, but their single control mode cannot meet the needs of simultaneous, differentiated irrigation of multiple fields. Gate valves are typically used to shut off main pipes to ensure a stable water supply and similarly lack the ability to irrigate multiple areas.

[0004] With the accelerated development of agricultural modernization, higher requirements are being placed on the automation, intelligence, and cost control of farmland irrigation. Traditional irrigation valves are unable to achieve automated and intelligent irrigation. To address this, some have proposed automatic irrigation valves. For example, utility model patent ZL202420498484.6 proposes a water-saving automatic irrigation valve for agriculture. The valve body and valve mechanism are fixedly connected to the upper end of the valve body. The valve mechanism ensures a secure and stable connection between the valve and the irrigation pipe during use, effectively preventing water leakage. The filter assembly utilizes a multi-stage filtration structure to effectively remove impurities and ferromagnetic particles from the irrigation water source, ensuring water quality and preventing damage to the valve and irrigation system. The manual operation assembly is equipped with a valve stem, connecting rod, and manual lever, allowing the user to manually intervene when necessary to achieve precise control of irrigation water volume and timing. The drive connection assembly utilizes a drive motor, sealing gasket, and valve core to achieve automatic control functions. Combined with pressure, temperature, flow, and liquid level information feedback from the sensor assembly, the valve opening can be intelligently adjusted to achieve precise irrigation results. Another example is the utility model patent with patent number ZL202222066105.X, which proposes an agricultural water-saving automatic irrigation valve. The valve includes a main valve body with a cavity fixedly disposed inside the main valve body, a top cover fixedly mounted on the top of the main valve body, an air sensor fixedly mounted on the top of the top cover, a signal transmitter fixedly mounted on one side of the air sensor, a telescopic motor fixedly mounted inside the top cover, a connecting rod fixedly mounted on the bottom of the telescopic motor, a blocking plug fixedly mounted on the bottom of the connecting rod, an inlet pipe fixedly mounted on one side of the main valve body, a connecting seat fixedly mounted on the bottom of the main valve body, and an auxiliary valve body fixedly mounted on the bottom of the connecting seat. This agricultural water-saving automatic irrigation valve uses air sensors and soil sensors to detect the water content of the air and soil outside the crops, thereby achieving real-time detection of the crop growth environment and automatically controlling the valve to ensure that the crops grow in a suitable living environment.

[0005] Both of the above-mentioned automatic irrigation valves have the advantages of automatic control and precise irrigation, but both are models in which a single valve corresponds to a single field area. A valve needs to be installed in each field area, which not only leads to high costs for valve procurement, installation and maintenance, but also increases the difficulty of management, and needs further improvement. Summary of the Invention

[0006] The purpose of the present invention is to provide a multi-position automatic sequential distribution valve device that can realize automated, intelligent and precise control of irrigation of multiple fields, effectively reduce the manpower and equipment costs of field management, improve irrigation efficiency and water resource utilization, and provide an efficient and economical solution for modern agricultural irrigation.

[0013] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0014] The following is a further description with reference to the accompanying drawings and specific embodiments: like Figure 1 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 10 As shown, a multi-position automatic sequential distribution valve device includes a water inlet A, a connecting hose B, a multi-way adapter C, a cam-controlled valve D, and a DC motor unit E. The multi-way adapter C has a water inlet connected to the water inlet pipe A for introducing water. The multi-way adapter C also has multiple water outlets. The number of connecting hoses B matches the number of water outlets. Each connecting hose B is connected to the multiple water outlets of the multi-way adapter C, and its other end serves as an outlet to different fields, thereby achieving preliminary water distribution. In this embodiment, the multi-way adapter C is a four-way adapter, corresponding to the four connecting hoses B. The cam control valve D, the core control component, is equipped with the same number of clamping structures as the connecting hoses B. Each connecting hose B passes through these clamping structures one by one. A DC motor E is connected to the cam control valve D, providing power to the cam control valve D, driving it to open and close each clamping structure, thereby precisely controlling the flow of water to different fields and completing the irrigation task. like Figure 2 、 Figure 4 and Figure 5 As shown, the cam-controlled valve D includes a valve core 3 and a valve body. The valve core 3 is composed of a base plate 5, a slider 6, a shock-absorbing spring 7, a cam plate 8, a transmission shaft 9, and a base plate block 12; the valve body is composed of a cover plate 2. The connecting hose B passes through the gap between the outer side of the slider 6 and the base plate 5. The slider 6 is placed in the groove of the base plate 5 and can slide within the groove. The shock-absorbing spring 7 is located between the slider 6 and the base plate block 12 and is installed through spring slots 36 and 37. It can provide a buffer for the movement of the slider 6, reduce mechanical wear, and ensure the stability of the slider 6 during movement. The cam plate 8 and the transmission shaft 9 are assembled through splines to ensure stable power transmission; the transmission shaft 9 is connected to the base plate 5 through the characteristic hole 34 to achieve a stable combination of the various components of the valve core 3. like Figure 2 、 Figure 4 and Figure 5 As shown, the cam plate 8 comprises a lower cam plate 10 and an upper cam plate 11, with the lower cam plate 10 positioned below the upper cam plate 11. The lower cam plate 10 is made of metal to ensure structural strength and durability, while the upper cam plate 11 is made of plastic to reduce interference caused by magnetic conductivity. A rubidium magnet is embedded in a square slot on the upper cam plate 11, with specific points 23-27. A magnetic switch 13 is glued to the outside of the cover plate block 1, which is connected to the cover plate 2. This adjusts the distance between the magnetic switch 13 and the rubidium magnet to eliminate signal interference caused by excessive magnetism. Magnetic switch points 28-32 are provided on the cover plate block 1, which work in conjunction with the rubidium magnet points to provide signal feedback. The cover plate 2, valve core 3, and connecting plate 4 are connected by bolts through holes 21 (on the connecting plate) and 22 (on the base plate). Connecting plate 4 is located between DC motor E and cam control valve D. DC motor E is bolted to connecting plate 4 through hole 38 (motor connection). The end of drive shaft 9 is connected to DC motor E. Connecting plate 4 connects DC motor E and cam control valve D, balancing the combined external forces, preventing relative motion between them, and ensuring accurate and stable power transmission. like Figure 6 and Figure 7 As shown, the device also includes an electrical control box 39, a solar panel 14, a water pressure sensor 15, and a Lora module 16. The electrical control box 39 and solar panel 14 are mounted on a bracket 40. The solar panel 14 is used to power the Lora module 16, ensuring energy supply for the control unit. The Lora module 16 is signal-connected to the Lora gateway 17, cloud server 18, and smart terminal 19, and is also signal-connected to the DC motor unit E. The water pressure sensor 15, located in the outlet pipe, is also signal-connected to the Lora module 16, enabling data transmission and interaction. The working principle of the present invention is as follows: when the irrigation operation is started, the user sends an irrigation instruction to the cloud server 18 through the dedicated software on the smart terminal 19. After receiving the instruction, the cloud server 18 accurately sends the instruction to the designated Lora module 16 via the Lora gateway 17. After receiving the instruction, the Lora module 16 drives the DC motor group E to start rotating, and the power is transmitted to the cam plate 8 through the transmission shaft 9 in turn. As the cam plate 8 rotates, its unique contour shape pushes the slider 6 to slide in the groove of the base plate 5. When a certain field needs to be irrigated, the cam plate 8 rotates to the corresponding position, causing the corresponding slider 6 to loosen the connecting hose B. At this time, the water flow can flow to the target field through the connecting hose B; if a certain channel is to be closed, the cam plate 8 continues to rotate, prompting the slider 6 to clamp the connecting hose B, thereby blocking the water flow. During the rotation of the cam plate 8, when the rubidium magnet on the cam upper plate 11 coincides with the position of the magnetic switch 13 on the cover plate block 1, the magnetic switch 13 transmits a signal. This signal is transmitted to the smart terminal 19 via the Lora module 16, the Lora gateway 17, and the cloud server 18. The smart terminal 19 analyzes and processes the signal and then feeds it back to the DC motor E. This precisely controls the operation and shutdown of the DC motor E, enabling precise control of the cam control valve D and ensuring that each pipe clamping structure opens and closes according to the predetermined program. Furthermore, the water pressure sensor 15 located in the outlet pipe monitors the water pressure data in real time and transmits the data to the smart terminal 19 via the Lora module 16, the Lora gateway 17, and the cloud server 18. The smart terminal 19 analyzes and processes the water pressure data and then controls the DC motor E based on the actual situation, dynamically adjusting the irrigation process to ensure effective irrigation.
