Description

Technical Field

[0001] This invention relates to the field of irrigation, specifically to an irrigation device with a function of monitoring water flow. Background Technology

[0002] In existing irrigation filtration devices, to prevent silt particles, suspended impurities, or biological deposits carried in the raw water source from entering the pipe network, filter pipes or screen structures are mostly installed at the inlet end, and the filtration parts are maintained through regular cleaning or supporting cleaning mechanisms. However, the existing filtration cleaning structures are mostly concentrated in a one-sided cleaning mode, that is, they usually only scrape or wash the impurities attached to the outer wall or outer surface of the filter pipe, and it is difficult to act on the inner wall of the filter pipe and the internal flow channel area at the same time. With the long-term operation of the irrigation system, the deposition of impurities on the inner and outer sides of the filter pipe often shows a synchronous accumulation trend. If only the outer wall is cleaned, the deposited dirt in the inner wall area will continue to affect the water flow cross section and seepage path, thus forming residual blockage risks, leading to a gradual decrease in filtration efficiency, a shortened maintenance cycle, and even the problem of frequent disassembly, maintenance, and shutdown for cleaning, which is difficult to meet the long-term stable operation requirements under large-scale irrigation conditions.

[0003] For example, Chinese patent application CN202510054353.8, entitled "An Irrigation Device with Water Flow Monitoring Function," discloses a technical solution that uses a flow meter to monitor changes in water flow at the inlet end to determine whether there is a tendency for clogging in the filtration section, and activates a cleaning device to clean the filtration structure at the inlet end in abnormal situations. This solution can remove impurities from the outer surface of the filtration structure, thereby improving the clogging state to some extent; however, its cleaning effect is mainly concentrated on the outside of the filtration structure, and it still cannot simultaneously treat the deposited dirt on the inner wall of the filter tube or the inner filter hole area. When there are differences in the clogging conditions on the inside and outside of the filter tube or when they accumulate simultaneously, a single cleaning path on the outside may still result in the inability to eliminate residual clogging on the inner wall in time, thus affecting the overall water flow capacity of the filtration structure and the stability of system operation.

[0004] In summary, existing irrigation filtration and cleaning devices generally suffer from the following shortcomings: Firstly, the cleaning range is limited to one side of the filter structure, making it impossible to clean the inner and outer walls of the filter tube simultaneously. Secondly, the cleaning process is usually accompanied by large flow disturbances or the need to stop water for maintenance, which is not conducive to stable water supply under continuous irrigation conditions. Third, the accumulation of residual dirt can easily lead to long-term performance degradation of the filter unit, and the system reliability and operation and maintenance efficiency still need to be improved.

[0005] Therefore, it is necessary to propose a filter cleaning structure that can dynamically clean both the inner and outer walls of the filter tube simultaneously and minimize the impact of water supply during the cleaning process, in order to overcome the above-mentioned technical defects. Summary of the Invention

[0006] To address the technical problems of existing irrigation filtration devices that can only clean one side of the filter structure and cannot simultaneously clean the inner and outer walls of the filter tube, leading to the accumulation of residual dirt, decreased filtration capacity, frequent maintenance, and significant impact on water supply continuity during the cleaning process, this invention proposes an integrated filtration and cleaning structure that can achieve simultaneous cleaning of the inner and outer walls of the filter tube through the synergistic action of internal and external cleaning components, while maintaining stable water flow in the system during the cleaning process. Specifically, it is an irrigation device with water flow monitoring function.

[0007] The present invention solves the above-mentioned technical problems through the following technical solutions: The present invention provides an irrigation device with a water flow monitoring function, including an inlet filtration mechanism and a water pump. The inlet filtration mechanism is connected to the inlet end of the water pump, and a flow meter is installed on the pipeline between the inlet filtration mechanism and the inlet end of the water pump. The water inlet filtration mechanism includes an arc-shaped filter tube, with an inner cleaning component and an outer cleaning component that can rotate synchronously inside and outside the filter tube, respectively. The inner and outer cleaning components are coaxially arranged to clean the outer and inner walls of the filter tube simultaneously. The water pump's outlet is connected to the irrigation module via a pipeline. The irrigation module includes a connecting pipeline and a nozzle. The water pump connects to the connecting pipeline, and the water is finally sprayed out by the nozzle.

[0008] The rotating internal and external cleaning components, working in conjunction with the arc-shaped filter tube, can simultaneously clean impurities and dirt from both the inner and outer walls of the filter tube. Furthermore, because both the internal and external cleaning components are in motion during the cleaning process, they do not significantly impact the water flow rate.

[0009] In this technical solution, the internal cleaning component includes a mounting ring, which is coaxially arranged with the filter tube, and multiple cleaning units arranged in a ring array are fixed on the surface of the mounting ring. The drive component drives the mounting ring to rotate, and the rotating mounting ring drives the cleaning units on its surface to enter and exit the filter tube in sequence, thereby cleaning the inside of the filter tube.

[0010] In this technical solution, the cleaning unit is a block structure with a circular cross-section, and the outer annular sidewall can be attached to the inner wall of the filter tube or form an equidistant annular gap with the inner wall of the filter tube. One or both circular sidewalls of the cleaning unit are recessed inward to form a circular holding plate, and a raised skirt plate with an annular structure is formed at the edge.

[0011] In this technical solution, a connecting pipe for water outlet is fixed on the outer wall of the middle area of ​​the filter tube. The connecting pipe is connected to one end of the flow meter through a connecting pipe. The connection between the connecting pipe and the filter tube is covered with a rigid filter screen, and the filter screen is flush with the inner wall of the filter tube.

[0012] The diameter of the filter holes on the filter screen is smaller than the diameter of the filter holes on the holding plate.

[0013] The filter holes on the filter tube are preferably concentrated in the middle area, and the diameter of the filter holes on the holding plate is smaller than that of the filter holes on the filter tube. Even if the internal cleaning component stops at any point in time, there are at least two cleaning units inside the filter tube, and the two cleaning units are located on both sides of the connecting tube.

[0014] In this technical solution, the drive assembly includes a drive component, a connecting disk is fixed on the output shaft of the drive component, and multiple transmission rods arranged in a ring array are fixed on the connecting disk, with one end of each transmission rod fixed on a bearing ring; The support ring is fitted into the arc-shaped groove on the surface of the filter tube, and the cleaning unit is fixed to the annular outer wall of the support ring.

[0015] The drive unit rotates the connecting disc, which in turn rotates the bearing ring connected to the transmission rod. This, in turn, causes the cleaning unit and the mounting ring to rotate, allowing the cleaning unit on the mounting ring to sequentially enter and exit the inner cavity of the filter tube, thus completing the cleaning of the filter tube's interior.

[0016] In this technical solution, both the filter tube and the drive assembly are fixed on the mounting assembly. The mounting assembly includes a mounting platform, and multiple support rods are fixed to the bottom of the mounting platform. The filter tube is fixed to the mounting platform by the rods, and a mounting bracket is fixed on the mounting platform. The mounting bracket is used to install the drive assembly.

[0017] The present technical solution also includes a vibration component, which includes at least one striking part fixed in position and a trigger part that rotates synchronously with the drive component. The trigger part rotates with the drive component. After rotating to the striking part, it drives the striking part to run. The striking part strikes the internal cleaning component or the area connected to it.

[0018] In this technical solution, the striking component includes a bearing rod, one end of which is fixed to a bearing frame, and one end of a fixed rod is rotatably connected to the bearing frame. The other end of the fixed rod is fixed to a striking hammer. The triggering part includes a drive plate, one side of which is inclined to form a drive ramp. The rotating drive plate can overlap with the fixed rod and drive the fixed rod to rotate. A coil spring is provided at the connection between the fixed rod and the support frame.

[0019] The fixed rod is located on the circular trajectory of the drive plate's rotation. As the drive plate rotates with the transmission rod, it passes the fixed rod. The drive ramp of the drive plate first contacts the fixed rod, lifting it and causing it to rotate. The coil spring is compressed, retaining its elastic potential energy. When the drive plate disengages from the fixed rod, the fixed rod rotates in the opposite direction under the action of the coil spring, causing the striking hammer to strike the transmission plate, thereby vibrating the cleaning unit and the scraping arc plate, shaking off impurities from their surfaces.

[0020] The vibration component can strike the inner and outer cleaning components, causing impurities and dirt to detach from them.

[0021] In this technical solution, the connecting pipeline includes a conventional irrigation circuit, an alternating irrigation circuit, and a regional irrigation branch network. A valve-controlled switching component is used to distribute and switch the filtered water flow between the conventional irrigation circuit and the alternating irrigation circuit. Conventional irrigation circuits are used to undertake the task of continuous irrigation water supply for basic infrastructure under normal operating conditions; The alternating irrigation circuit includes an alternating irrigation main line and several regional irrigation branches branching off from the main line. Each regional irrigation branch is equipped with a valve control unit for independently controlling the on / off state.

[0022] This technical solution also includes a control and communication module, which is electrically connected to the inlet filtration mechanism, the valve control switching component and each valve control unit, and is used to collect system operating parameters and uniformly regulate water flow distribution and irrigation mode.

[0023] Regional irrigation branch networks are used to irrigate different farming areas or crop planting units in separate zones. Each valve control unit can achieve rotational irrigation, intermittent irrigation or phased water supply under the scheduling of the control and communication module.

[0024] When the filter component enters the self-cleaning working state, the control and communication module controls the valve-controlled switching component to switch the water flow at least partially to the alternating irrigation circuit, so that the alternating irrigation circuit undertakes the task of transitional irrigation water supply during the self-cleaning process.

[0025] Under conditions of high irrigation load or fluctuating pipeline pressure, the alternating irrigation circuit serves as a diversion compensation channel for the main circuit, used to share part of the water supply task and improve overall operational stability.

[0026] In this technical solution, the control and communication module realizes irrigation loop switching control, zone rotation irrigation control, and continuous water supply control during self-cleaning maintenance based on irrigation plans, water volume monitoring data, and filter component status.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0028] The positive and progressive effects of this invention are as follows: By coordinating a self-rotating internal cleaning component located inside the filter tube with an external cleaning component located outside the filter tube, and ensuring that both components correspond to the inner and outer walls of the arc-shaped filter tube respectively, the internal and external cleaning components rotate synchronously along the axial or circumferential direction of the arc-shaped filter tube when the system enters cleaning mode. This allows for the simultaneous removal of impurities, deposits, and biofilm adhering to both the inner and outer sides of the filter tube. Compared to traditional structures that only clean one side of the wall, this solution can simultaneously restore the water flow and dispersion capacity of both the inner and outer walls of the filter tube in a single cleaning process. This avoids the problem of residual clogging caused by cleaning only one side, improving the overall maintenance efficiency and service life of the filter unit.

[0029] Furthermore, the dynamic working characteristics of the internal and external cleaning components enable the cleaning process to have both "continuous operation" and "online maintenance" features. That is, without shutting off the water source or disassembling the filter components, the risk of gradually accumulating blockage can be eliminated in real time, thereby achieving the synergistic coexistence of filtration and cleaning functions and significantly improving the reliability and stability of the system under long-term operating conditions.

[0032] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0033] like Figure 1 and Figure 2 As shown, an irrigation device with water flow monitoring function includes an inlet filter mechanism c and a water pump a. The inlet filter mechanism c is connected to the inlet end of the water pump a, and a flow meter b is installed on the pipeline between the inlet filter mechanism c and the inlet end of the water pump a. The water inlet filtration mechanism c includes an arc-shaped filter tube 8. An inner cleaning component 3 and an outer cleaning component 6 that can rotate synchronously are respectively provided inside and outside the filter tube 8. The inner cleaning component 3 and the outer cleaning component 6 are coaxially arranged to clean the outer wall and inner wall of the filter tube 8 synchronously. The outlet of water pump a is connected to irrigation module d through a pipeline. Irrigation module d includes a connecting pipeline and a nozzle. Water pump a pumps irrigation water into the connecting pipeline, and finally sprays it out from the nozzle.

[0034] In this application, the size, dimensions, and relative spatial arrangement of the water pump (a), flow meter (b), and inlet filter (c) are not limited to the specific forms and proportions shown in the accompanying drawings. Depending on the actual application requirements, these components can be of different specifications, sizes, or arrangements to adapt to the piping conditions, water flow rate, water pressure conditions, and installation environment of the irrigation system. In other words, the accompanying drawings are only used to illustrate the connection relationships and functional combinations between the components and should not be construed as limitations on the size, shape, or arrangement of the components. In implementation, the water pump, flow meter, and inlet filter can be optimized according to the system scale, irrigation load, and construction conditions to ensure the system's versatility, scalability, and applicability.

[0035] Example 1 like Figures 4-5 As shown, the internal cleaning component 3 includes a mounting ring 31, which is coaxially arranged with the filter tube. Multiple cleaning units 32 arranged in a ring array are fixed on the surface of the mounting ring 31. The drive component 2 drives the mounting ring 31 to rotate, and the rotating mounting ring 31 drives the cleaning unit 32 on its surface to enter and exit the filter tube 8 in sequence, thereby cleaning the inside of the filter tube 8.

[0036] The cleaning unit 32 is a block structure with a circular cross-section, and the outer annular sidewall can be attached to the inner wall of the filter tube 8 or form an equidistant annular gap with the inner wall of the filter tube 8. One or both circular sidewalls of the cleaning unit 32 are recessed inward to form a circular holding plate 321, and a raised skirt plate 322 with an annular structure is formed at the edge.

[0037] A connecting pipe 41 for water outlet is fixed on the outer wall of the middle area of ​​the filter tube 8. The connecting pipe 41 is connected to one end of the flow meter b through the connecting pipe 4. The connection between the connecting pipe 41 and the filter tube 8 is covered with a rigid filter screen, and the filter screen is flush with the inner wall of the filter tube 8, so as not to affect the passage of the cleaning unit 32.

[0038] Connecting pipe 4, flow meter b, and water pump a are connected via flange 5.

[0039] The diameter of the filter holes on the filter screen is smaller than the diameter of the filter holes on the holding plate 321.

[0040] The filter holes on the filter tube 8 are preferably concentrated in its middle area, and the diameter of the filter holes on the holding plate 321 is smaller than that of the filter holes on the filter tube. When the internal cleaning component 3 stops at any point in time, there are at least two cleaning units 32 inside the filter tube 8, and the two cleaning units 32 are located on both sides of the connecting tube 41.

[0041] The water source is filtered once through the filter tube 8 and the filter holes on the holding plate 321, and then filtered twice through the filter screen. At the same time, the internal cleaning component 3 and the external cleaning component 6 are used to clean the environment of the primary filtration, ensuring filtration efficiency and stability of the secondary filtration.

[0042] Although the latter three types of filter holes are different, the cleaning process is dynamic, so it is both cleaning and filtering.

[0043] Specifically, the water source first undergoes primary filtration through the filter pipe 8 and the filter holes on the holding plate 321 to intercept larger particles and suspended solids. Subsequently, the water flows through the filter screen for secondary filtration, further removing smaller particles or fine impurities to ensure the cleanliness of the irrigation water. During this process, the internal cleaning component 3 and the external cleaning component 6 act on the inner and outer walls of the filter pipe 8, respectively, to dynamically clean the environment of the primary filtration, effectively removing impurities and dirt adhering to the filter pipe wall and filter holes.

[0044] Because the internal and external cleaning components continuously rotate or slide during operation, the cleaning process and water flow occur simultaneously. Therefore, while cleaning impurities, the filtration function continues to operate, achieving a synchronous working mode of "cleaning and filtering at the same time." This structure not only improves the efficiency of the primary filtration of the filter tube but also ensures the stability and long-term reliability of the secondary filtration process, thereby effectively reducing the risk of clogging and improving the overall continuity of system operation and the stability of irrigation water quality.

[0045] Example 2 like Figure 5 As shown, the drive assembly 2 includes a drive component 22, a connecting disk 23 is fixed on the output shaft of the drive component 22, and a plurality of transmission rods 21 arranged in a ring array are fixed on the connecting disk 23. One end of each transmission rod 21 is fixed on a bearing ring 24. like Figure 11 As shown, the support ring 24 is fitted onto the arc-shaped through groove 81 on the surface of the filter tube 8, and the cleaning unit 32 is fixed on the annular outer wall of the support ring 24.

[0046] The drive unit 22 drives the connecting plate 23 to rotate, which in turn drives the bearing ring 24 connected to the transmission rod 21 to rotate. This causes the cleaning unit 32 and the mounting ring 31 to rotate, so that the cleaning unit 32 on the mounting ring 31 enters and exits the inner cavity of the filter tube 8 in sequence, thereby completing the cleaning of the inside of the filter tube 8.

[0047] The bearing ring 24, with its ring-shaped structure, blocks the arc-shaped through groove 81 of the filter tube 8 to prevent the filter tube 8 from failing.

[0048] When the internal cleaning component 3 requires sufficient strength, a reinforcing rod can be fixed on the outer wall of the bearing ring 24 on one side of the inner cavity of the filter tube 8, and the other end of the reinforcing rod is fixed on the mounting ring 31.

[0049] If the internal cleaning component 3 does not have high rigidity requirements, the mounting ring 31 can be directly removed, and the cleaning unit 32 can be directly fixed on the bearing ring 24.

[0050] Both the filter tube 8 and the drive assembly 2 are fixed on the mounting assembly 1. The mounting assembly 1 includes a mounting platform 11. Multiple support rods 12 are fixed to the bottom of the mounting platform 11. The filter tube 8 is fixed to the mounting platform by the rods. A mounting bracket 13 is fixed on the mounting platform 11. The mounting bracket 13 is used to install the drive assembly 22.

[0051] The driving component 22 is a motor, or a protective housing, or a motor installed inside the protective housing, with the main shaft output end of the motor fixed at the center of the connecting plate 23.

[0052] When a protective casing is present, the motor is installed inside the protective casing, and the protective casing is fixedly connected to the mounting bracket 13, with the motor's main shaft passing through the protective casing.

[0053] When only the motor is present, the motor is directly fixed to the mounting bracket 13.

[0054] The bottom of the support rod 12 is preferably a pointed structure for direct driving into the ground beneath the water surface.

[0055] The support rod 12 can also be replaced with other fixing structures to support the mounting platform 11.

[0056] Example 3 In this embodiment, the external cleaning component 6 includes a plurality of scraping arc plates 62 arranged in a ring array. The scraping arc plates 62 are attached to the outer wall of the filter tube 8, and the scraping arc plates 62 are fixed to the side wall of the bearing ring 24 located in the outer area of ​​the filter tube 8 by a fixing rod 61.

[0057] The scraping arc plate 62 is fixed to the bearing ring 24 by the fixed connecting rod 61, thereby driving the scraping arc plate 62 to make a circular motion to scrape off the dirt on the outer wall of the filter tube 8.

[0058] When installing the filter tube 8, it is preferable that both ends of the filter tube 8 extend out of the water surface.

[0059] Example 4 like Figure 7 and Figure 8 As shown, it also includes a vibration component 7, which includes at least one striking part fixed in position and a trigger part that rotates synchronously with the drive component 2; The trigger part rotates with the drive component 2. After rotating to the striking part, it drives the striking part to run. The striking part strikes the internal cleaning component 3 or the area connected to it.

[0060] The striking assembly includes a support rod 71, one end of which is fixed to a support frame 72, and one end of a fixing rod 75 is rotatably connected to the support frame 72. The other end of the fixing rod 75 is fixed to a striking hammer 76. The triggering part includes a drive plate 77. One side of the drive plate 77 is inclined to form a drive slope 771. The rotating drive plate 77 can overlap with the fixed rod 75 and drive the fixed rod 75 to rotate. A coil spring is provided at the connection between the fixed rod 75 and the support frame 72.

[0061] Preferably, the drive plate 77 is fixed on the transmission rod 21, and the hammer 76 strikes the transmission plate 78 on the inner ring of the bearing ring 24. The transmission plate 78 is located on one side of the corresponding transmission rod 21.

[0062] The end of the support rod 71 is fixed to the drive component 22 or the mounting platform 11.

[0063] The support frame 72 includes two first links and one second link, with the first links fixed at both ends of the second link.

[0064] A load-bearing crossbar 74 is fixed between the two first connecting rods. A self-rotating sleeve 73 is sleeved on the surface of the load-bearing crossbar 74. A fixed rod 75 is fixedly connected to the self-rotating sleeve 73. A coil spring is sleeved on the load-bearing crossbar 74. The two ends of the coil spring are fixed to the fixed rod 75 and the load-bearing crossbar 74, respectively.

[0065] The fixed rod 75 is located on the circular trajectory of the rotating drive plate 77. When the drive plate 77 rotates with the transmission rod 21, it passes the fixed rod 75. The driving inclined surface 771 of the drive plate 77 first contacts the fixed rod 75, and the driving inclined surface 771 pushes up the fixed rod 75, causing the fixed rod 75 to rotate. The coil spring is compressed, continuing its elastic potential energy. When the drive plate 77 disengages from the fixed rod 75, under the action of the coil spring, the fixed rod 75 rotates in the opposite direction, driving the striking hammer 76 to strike the transmission plate 78, thereby vibrating the cleaning unit 32 and the scraping arc plate 62, shaking off impurities from their surfaces.

[0066] The vibration component 7 can strike the inner cleaning component 3 and the outer cleaning component 6, causing impurities and dirt to be removed from the inner cleaning component 3 and the outer cleaning component 6.

[0067] like Figure 6 As shown, the rotation direction of the transmission rod 21 is from right to left.

[0068] Example 5 The connecting pipeline includes conventional irrigation circuits, alternating irrigation circuits, and regional irrigation branch network. A valve-controlled switching component is used to distribute and switch the filtered water flow between the conventional irrigation circuits and the alternating irrigation circuits. Conventional irrigation circuits are used to undertake the task of continuous irrigation water supply for basic infrastructure under normal operating conditions; The alternating irrigation circuit includes an alternating irrigation main line and several regional irrigation branches branching off from the main line. Each regional irrigation branch is equipped with a valve control unit for independently controlling the on / off state.

[0069] It also includes a control and communication module, which is electrically connected to the inlet filtration mechanism c, the valve control switching component and each valve control unit, respectively, and is used to collect system operating parameters and uniformly regulate water flow distribution and irrigation mode.

[0070] Regional irrigation branch networks are used to irrigate different farming areas or crop planting units in separate zones. Each valve control unit can achieve rotational irrigation, intermittent irrigation or phased water supply under the scheduling of the control and communication module.

[0071] When the filter component enters the self-cleaning working state, the control and communication module controls the valve-controlled switching component to switch the water flow at least partially to the alternating irrigation circuit, so that the alternating irrigation circuit undertakes the task of transitional irrigation water supply during the self-cleaning process.

[0072] Under conditions of high irrigation load or fluctuating pipeline pressure, the alternating irrigation circuit serves as a diversion compensation channel for the main circuit, used to share part of the water supply task and improve overall operational stability.

[0073] The control and communication module, based on irrigation plans, water volume monitoring data, and filter component status, enables irrigation loop switching control, zoned rotation irrigation control, and continuous water supply control during self-cleaning maintenance.

[0074] During the irrigation process, external water first enters the inlet filtration mechanism, where impurities are intercepted by the filter pipe and its inner wall pores. Under normal operating conditions, the water is preferentially supplied to the target irrigation area via the valve-controlled switching component. When the control and communication module determines that there is a tendency for blockage on the inner wall of the filter pipe based on flow monitoring or differential pressure monitoring results, and triggers the inlet filtration mechanism to enter self-cleaning mode, the system will first adjust the working state of the valve-controlled switching component, switching part or all of the water flow to the alternating irrigation circuit. At the same time, the alternating irrigation branch line in the predetermined area will be opened, so that this circuit will undertake the transitional irrigation task during the self-cleaning process.

[0075] After the internal cleaning component 3 and external cleaning component 6 complete the scraping and cleaning of the deposits on the inner wall of the filter pipe and restore the filtration capacity to a stable range, the control and communication module readjusts the valve control switching component to restore the system to a water supply mode dominated by the conventional irrigation circuit. Based on the irrigation plan, the alternating irrigation circuit is switched to intermittent rotation irrigation or standby operation. Through this process setting, the system can maintain continuous and stable irrigation water supply even under conditions such as self-cleaning of the inlet filter mechanism, flow fluctuations, or uneven local loads. Simultaneously, it achieves coordinated control of zoned rotation irrigation and water allocation, significantly improving the reliability and operational flexibility of the irrigation system.
