Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation equipment technology, specifically to an irrigation pipeline pressure balancing device. Background Technology

[0002] In agricultural irrigation, the stability of pipeline pressure is a key factor in ensuring irrigation efficiency, crop growth quality, and the lifespan of the irrigation system. In existing irrigation systems, factors such as fluctuations in water source pressure, switching of irrigation areas, and changes in pipeline length often lead to excessively high or low pressure within the pipelines. Excessive pressure can easily cause pipe ruptures and leaks at joints, increasing maintenance costs and wasting water resources; insufficient pressure can result in insufficient water output from distant irrigation equipment and uneven irrigation, negatively impacting crop growth.

[0003] Currently, most pressure regulating devices on the market have complex structures, low regulation accuracy, and are mostly single functions of depressurization or pressurization. They cannot achieve dynamic balance regulation based on changes in pipeline pressure, limiting their applicable scenarios and making it difficult to meet the needs of precision irrigation in modern agriculture.

[0004] Therefore, a pressure balancing device for irrigation pipelines is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an irrigation pipeline pressure balancing device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] An irrigation pipeline pressure balancing device includes a main pipe, a pressure detection module, a pressure regulation module, and a control module. The main pipe has an inlet and an outlet at both ends, each with a connecting flange. The pressure detection module includes a first pressure sensor at the inlet end and a second pressure sensor at the outlet end, both connected to the control module. The pressure regulation module includes a pressure relief component and a pressure boosting component. The pressure relief component includes a pressure relief pipe on the side wall of the main pipe, with a pressure relief valve. The end of the pressure relief pipe is connected to a return pipe, which connects to a water source tank in the irrigation system. The pressure boosting component includes a booster pump located in the middle of the main pipe, electrically connected to the control module. The control module includes a controller and a display screen. The controller is electrically connected to the pressure relief valve, the booster pump, the first pressure sensor, the second pressure sensor, and the display screen, and has a preset pressure threshold range.

[0008] Furthermore, the pressure relief valve is an electromagnetic pressure relief valve, and the booster pump is a variable frequency booster pump, in order to improve the response speed and accuracy of pressure regulation and meet the precise control requirements under different pressure fluctuation amplitudes.

[0009] Furthermore, the main body is provided with a filter assembly, which includes a filter cylinder and a filter screen. The filter cylinder is detachably connected to the main body and filters impurities in the water flow to prevent them from causing wear or blockage to the pressure sensor, valve and pump body.

[0010] Furthermore, the controller is a PLC controller, and the display screen is a touch screen. The PLC controller can efficiently process pressure signals and output control commands, while the touch screen facilitates real-time display of pressure data, working status, and manual setting of pressure thresholds.

[0011] Furthermore, the main body is made of PVC or stainless steel. PVC has good corrosion resistance and economy, while stainless steel is suitable for high-pressure or highly corrosive irrigation environments, thus improving the adaptability of the device.

[0012] Furthermore, the filter assembly is located between the water inlet of the main body and the first pressure sensor to ensure that impurities are filtered before the water flows into the pressure detection and regulation assembly, thus protecting the core components to the greatest extent.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a first pressure sensor and a second pressure sensor to detect the inlet and outlet pressure of the pipeline in real time. The control module automatically starts the pressure relief component or the pressure boosting component according to the pressure data to achieve dynamic balance adjustment of the pipeline pressure and ensure that the pressure is always within the preset threshold range.

[0015] 2. It integrates both pressure relief and pressure boosting functions, has a compact structure, is easy to operate, and is suitable for pressure regulation needs in different irrigation scenarios. It effectively avoids pipeline damage due to abnormal pressure and ensures uniform irrigation.

[0016] 3. It adopts an electromagnetic pressure relief valve and a variable frequency booster pump, in conjunction with a PLC controller, which has high adjustment accuracy and fast response speed. The pressure data can be viewed intuitively through the display screen, which is convenient for users to monitor and adjust parameters.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, an irrigation pipeline pressure balancing device includes a main pipe body 1, a pressure detection module, a pressure regulating module, and a control module. The main pipe body 1 has an inlet 2 and an outlet 3 at both ends, with connecting flanges 4 at both inlet 2 and outlet 3. The pressure detection module includes a first pressure sensor 5 located at the inlet end of the main pipe body 1 and a second pressure sensor 6 located at the outlet end of the main pipe body 1. Both the first pressure sensor 5 and the second pressure sensor 6 are connected to the control module. The pressure regulating module includes a pressure relief component and a pressure boosting component. The pressure relief component includes a pressure relief pipe 7 located on the side wall of the main pipe body 1, with a pressure relief valve 8 on the pressure relief pipe 7. A return pipe 9 is connected to the water source tank of the irrigation system. The pressurization component includes a booster pump 10 located in the middle of the main pipe 1, which is electrically connected to the control module. The control module includes a controller 11 and a display screen 12. The controller 11 is electrically connected to the pressure relief valve 8, the booster pump 10, the first pressure sensor 5, the second pressure sensor 6, and the display screen 12. The controller 11 has a preset pressure threshold range. Specifically, the first pressure sensor 5 and the second pressure sensor 6 continuously monitor the pressure at the inlet and outlet of the main pipe 1, converting the physical pressure signal into an electrical signal and transmitting it to the controller 11 in real time. The controller 11 is pre-programmed with a pressure threshold range that meets the needs of agricultural irrigation. When the pressure value detected by the first pressure sensor 5 or the second pressure sensor 6 exceeds the upper threshold, the controller 11 immediately sends an opening command to the electromagnetic pressure relief valve 8. Excess high-pressure water in the pipeline flows back to the water source tank through the pressure relief pipe 7 and the return pipe 9, achieving rapid pressure relief. Conversely, when the pressure value falls below the lower threshold, the controller 11 drives the variable frequency booster pump 10 to start, intelligently adjusting the pump's output power based on the pressure difference to precisely boost the water flow in the pipeline. This ensures that the pipeline pressure remains stable within the preset range, fundamentally preventing pipeline rupture and interface leakage caused by excessive pressure, and insufficient water output and uneven irrigation from remote irrigation equipment caused by excessively low pressure. This achieves dynamic and precise balance adjustment of the irrigation pipeline pressure.

[0027] like Figure 1 As shown, pressure relief valve 8 is an electromagnetic pressure relief valve, and booster pump 10 is a variable frequency booster pump. Specifically, the electromagnetic pressure relief valve has a fast response speed and can quickly open to relieve pressure when the pressure exceeds the upper limit of the threshold. The variable frequency booster pump can accurately adjust the output power according to the pressure demand and stably increase the pipeline pressure when the pressure is lower than the lower limit of the threshold. The combination of the two greatly improves the accuracy and efficiency of pressure regulation.

[0028] like Figure 1 , Figure 2As shown, the main body 1 is equipped with a filter assembly, which includes a filter cylinder 13 and a filter screen 14. The filter cylinder 13 is detachably connected to the main body 1. Specifically, the filter screen 14 adopts a honeycomb structure, which can effectively filter impurities such as silt and crop residues in the irrigation water, preventing them from clogging the pressure sensor and regulating valve. The filter cylinder 13 is detachable through a flange connection, which makes it convenient for users to clean or replace the filter screen 14 regularly, ensuring the long-term stable operation of the device.

[0029] like Figure 1 As shown, controller 11 is a PLC controller, and display screen 12 is a touch screen. Specifically, the PLC controller has powerful logic control capabilities, can accurately process the signals from the pressure sensor and output control commands; the touch screen can display the pressure data in the pipeline and the working status of the device in real time, and also supports users to manually set the pressure threshold, realizing visualized and convenient operation and monitoring.

[0030] like Figure 1 As shown, the main body 1 is made of PVC or stainless steel. Specifically, PVC is corrosion-resistant and low-cost, making it suitable for general agricultural irrigation scenarios; stainless steel has high compressive strength and long service life, making it suitable for harsh irrigation environments with high pressure and high corrosion. Users can choose the appropriate material according to their actual needs.

[0031] like Figure 1 As shown, the filter assembly is located between the water inlet 2 of the main body 1 and the first pressure sensor 5. Specifically, this arrangement can filter impurities before the water flows into the pressure detection and regulation assembly, thus protecting the core components such as the first pressure sensor 5, the pressure relief valve 8, and the booster pump 10 from impurities and extending their service life to the greatest extent.

[0032] In summary: First, the first pressure sensor 5 and the second pressure sensor 6 monitor the pressure at the inlet and outlet of the main pipe 1 in real time, respectively, converting the physical pressure signal into an electrical signal and continuously transmitting it to the controller 11. The controller 11 analyzes the received pressure signal in real time based on a built-in, manually adjustable pressure threshold range (adapted to different irrigation scenarios and crop types) to determine whether the pipeline pressure is higher than the upper threshold or lower than the lower threshold. If the pressure is determined to be too high, the controller 11 immediately sends an opening command to the electromagnetic pressure relief valve 8, allowing the high-pressure water in the pipeline to flow back through the pressure relief pipe 7 and the return pipe 9 to the outlet. The water source tank is depressurized quickly; if the pressure is determined to be too low, the variable frequency booster pump 10 is started, and the output power is intelligently adjusted according to the pressure difference to accurately boost the pressure until the pressure is restored to the threshold range; at the same time, the filter components (filter cylinder 13 and filter screen 14) located between the water inlet 2 and the first pressure sensor 5 will pre-filter impurities in the water to avoid clogging the core components; the display screen 12 displays the pressure data, working status and threshold in real time, supporting intuitive monitoring and manual adjustment by the user. Finally, through the coordinated action of each module, the pressure of the irrigation pipeline is ensured to remain stable within a reasonable range, ensuring uniform and efficient irrigation.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
