Description

Technical Field

[0001] The present invention relates to the technical field of natural gas transmission equipment, and in particular to an intelligent pressure regulating device for natural gas pipelines. Background Art

[0002] Although the intelligent pressure regulating device for natural gas pipelines has many advantages, there are also some disadvantages, mainly including the following aspects:

[0003] (1) Limited adaptability to complex environments. The electronic components and sensors of the intelligent pressure regulating device are relatively sensitive to environmental conditions. In harsh environments such as high temperature, high humidity, and dust, its performance may be affected, resulting in increased measurement errors or equipment failures. For example, in long-distance pipelines in desert areas, dust may enter the device interior and cover the sensor surface, affecting its accurate perception of parameters such as pressure and flow rate.

[0004] For some complex geographical environments, such as mountainous areas and swampy areas, the installation and maintenance of the device are difficult, which may affect its normal operation and maintenance.

[0005] (2) Dependence on energy supply. The intelligent pressure regulating device usually requires electricity to drive its controller, sensors, and regulating valves and other components. Once the power supply fails or is interrupted, the device may not work properly, resulting in the failure of the pressure regulating function. In some remote areas, the power supply may be unstable, or special power supply facilities need to be built, which increases the risk and cost of device operation. Summary of the Invention

[0006] The present invention provides an intelligent pressure regulating device for natural gas pipelines to solve the above-mentioned existing technical problems.

[0007] The technical solution of the present invention is implemented as follows:

[0008] An intelligent pressure regulating device for natural gas pipelines includes a natural gas transmission pipeline. A pressure regulating valve and a unit for controlling the pressure regulating valve are provided on the natural gas transmission pipeline. And on one side of the transmission pipeline, there is an intelligent observation system, including a trapezoidal transportation channel integrally formed with the transmission pipeline on one side. Traveling tracks are provided on both sides of the transportation channel, and a data acquisition trolley is provided on the traveling tracks. The trolley travels on the tracks by controlling pulleys with a motor.

[0009] Preferably, the intelligent observation system further includes a sub-control system every 1 - 3 KM on the natural gas transmission pipeline. The sub-control system includes an information acquisition system and a power supply system.

[0010] Preferably, the information acquisition system includes a plurality of information acquisition probes arranged in the pipeline section to which the sub-control system belongs, including a temperature sensor, a humidity sensor, and a pipeline pressure sensor. The information collected by the temperature sensor, the humidity sensor, and the pipeline pressure sensor is stored in the sub-control system, and the sub-control system is wirelessly connected to the unit of the pressure regulating valve.

[0011] Preferably, the data acquisition trolley further includes a data storage medium. When the wireless signal connection between the sub-control system and the unit of the pressure regulating valve is disconnected, when the data acquisition trolley passes by the sub-control system, the sub-control system is connected to the data acquisition trolley through a Bluetooth signal, and the collected data is sent to the trolley. After the trolley returns to the unit of the pressure regulating valve, the data is then interacted with the unit.

[0012] Preferably, the power supply system includes an active wireless charging system and an infrared sensor. When the trolley passes by the pipeline section of the sub-control system, the infrared sensor obtains the trolley information and sends it to the control system of the trolley. At this time, the travel distance count of the trolley is reset to zero and marked as pipeline section n in its control system. When the trolley needs to be charged, after staying above the power supply system for more than 5 seconds, the wireless charging system is turned on to charge the trolley's power supply.

[0013] Preferably, the sub-control system is arranged below the track and includes a square outer shell. An infrared sensor is arranged above the outer shell, and a wireless charger is built into the outer shell.

[0014] Preferably, a power line is also arranged in the trapezoidal transportation channel to supply power to the pressure regulating valve, the unit controlling the pressure regulating valve, and the sub-control system respectively.

[0015] In view of the limited adaptability to complex environments in the present invention, by using the sub-control systems distributed along the pipeline, even if some devices are affected by harsh environments, the overall data acquisition sensors can still operate normally. In complex geographical environments such as mountains and swamps, the sub-control systems are located inside the pipeline, with small volume and relatively simple installation, reducing the installation difficulty and being not affected by the environment. At the same time, the data acquisition trolleys can shuttle flexibly for inspection, facilitating maintenance personnel to discover and solve problems in a timely manner, and improving the operation stability of the equipment in complex environments.

[0016] Regarding the problem of relying on energy supply, the power line in the trapezoidal transportation channel supplies power to the pressure regulating valve, control unit, and sub-control system to ensure stable power for key equipment. The power supply system of the sub-control system is equipped with an active wireless charging function to provide mobile charging support for the data acquisition trolley. When the main power supply fails, the trolley can still continue to work with the charged power, complete data acquisition and transmission, and ensure that the pressure regulating valve unit can obtain key information, maintaining the pressure regulating function to a certain extent. Moreover, the wireless charging system reduces the wiring requirements and the power supply risks caused by difficult wiring in remote areas, improving the energy reliability of the equipment and reducing the construction and maintenance costs.

[0023] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the exemplary embodiments will be described in detail herein, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of methods and systems consistent with some aspects of the present application as detailed in the appended claims.

[0024] Embodiment 1

[0025] An intelligent pressure regulating device for natural gas pipelines, including a natural gas transmission pipeline, is provided with a pressure regulating valve and a unit for controlling the pressure regulating valve on the natural gas transmission pipeline, and an intelligent observation system is arranged on one side of the transmission pipeline, including a trapezoidal transportation channel integrally formed with and on one side of the transmission pipeline. Traveling tracks are arranged on both sides of the transportation channel, and a data acquisition trolley is arranged on the traveling tracks. The trolley travels on the tracks by controlling pulleys with a motor.

[0026] Preferably, the intelligent observation system further includes a sub-control system every 1 - 3 KM on the natural gas transmission pipeline. The sub-control system includes an information acquisition system and a power supply system.

[0027] Setting up sub-control systems every 1 - 3 KM on the natural gas transmission pipeline greatly improves the fineness and coverage of data acquisition. On the one hand, the information acquisition system of the sub-control system can monitor the pipeline section in real time and comprehensively. Each information acquisition probe obtains data at close range, improving the accuracy of parameter acquisition such as temperature, humidity, and pipeline pressure. On the other hand, when a certain sub-control system fails, it will not affect the normal operation of other sub-control systems, ensuring the continuity of overall data acquisition and enhancing the reliability and stability of the system.

[0028] Preferably, the information acquisition system includes multiple information acquisition probes arranged in the pipeline section belonging to the sub-control system, including a temperature sensor, a humidity sensor, and a pipeline pressure sensor. The information collected by the temperature sensor, humidity sensor, and pipeline pressure sensor is stored in the sub-control system. The sub-control system is wirelessly connected to the unit of the pressure regulating valve.

[0029] Multiple information acquisition probes (temperature, humidity, and pressure sensors) work together to reflect the state of natural gas in the pipeline from multiple dimensions. The temperature sensor can monitor the temperature change of natural gas to prevent the impact on transportation safety due to abnormal temperature. The humidity sensor can prevent pipeline corrosion caused by moisture condensation. The pipeline pressure sensor is directly related to the precise regulation of the pressure regulating valve. The information collected by these probes is stored in the sub-control system for timely analysis and processing. Moreover, the sub-control system is wirelessly connected to the pressure regulating valve unit, capable of quickly transmitting data, providing a real-time basis for pressure regulating decisions, ensuring that the pressure regulating valve responds promptly to parameter changes in the pipeline, and maintaining the stable transportation of natural gas.

[0030] Preferably, the data acquisition trolley further includes a data storage medium. When the wireless signal connection between the sub-control system and the unit of the pressure regulating valve is disconnected, when the data acquisition trolley passes by the sub-control system, the sub-control system is connected to the data acquisition trolley through a Bluetooth signal, and the collected data is sent to the trolley. After the trolley returns to the unit of the pressure regulating valve, the data is then exchanged with the unit.

[0031] When the wireless signal between the sub-control system and the pressure regulating valve unit is disconnected, the combination of the information storage system and Bluetooth communication becomes a powerful guarantee for data transmission. The data acquisition trolley can temporarily act as a data carrier, obtain data from the sub-control system through Bluetooth and store it to avoid data loss. After the trolley returns to the pressure regulating valve unit, it exchanges data, ensuring that the pressure regulating valve unit can always obtain comprehensive data for analysis and decision-making, maintaining the coherence and stability of the overall operation of the equipment, and reducing the risk of control lag caused by communication failures.

[0032] Preferably, the power supply system includes an active wireless charging system and an infrared sensor. When the trolley passes by the pipeline section of the sub-control system, the infrared sensor obtains the trolley information and sends it to the control system of the trolley. At this time, the travel distance count of the trolley is reset to zero and marked as pipeline section n in its control system. When the trolley needs to be charged, after staying above the power supply system for more than 5 seconds, the wireless charging system is activated to charge the trolley's power supply.

[0033] The active wireless charging system provides a convenient and efficient charging method for the data acquisition trolley. The trolley does not need to physically plug and unplug the charging cable, reducing the wear and failure risks associated with contact charging and improving the durability of the trolley. The infrared sensor is not only used to obtain the trolley information, realize distance marking and counting, but also can accurately locate the trolley position, facilitating the trolley to plan the charging path to ensure that it can quickly find the nearest charging point when the battery is low, improving the working efficiency of the trolley and ensuring the uninterrupted progress of data acquisition work.

[0034] Preferably, the sub-control system is arranged below the track and includes a square outer shell. An infrared sensor is arranged above the outer shell, and a wireless charger is built into the outer shell.

[0035] The sub-control system is arranged below the track. The square outer shell is designed to be compact and stable, saving space while effectively protecting the internal components. The infrared sensor above the outer shell is convenient for capturing the upward information of the trolley. The built-in wireless charger reduces external interference while ensuring the charging function, improving the charging stability. This structural design not only facilitates the installation and maintenance of the sub-control system, but also ensures its normal operation in a complex environment, enhancing the overall reliability and adaptability of the equipment.

[0036] Preferably, a power cord is also arranged in the trapezoidal transportation channel to supply power to the pressure regulating valve, the unit controlling the pressure regulating valve, and the sub-control system respectively.

[0037] The power cord supplies power to the pressure regulating valve, the unit controlling the pressure regulating valve, and the sub-control system, providing a stable and reliable power source. Compared with relying on external unstable power sources or individual small independent power sources, centralized power supply can ensure sufficient and stable power during the operation of the equipment, reducing equipment failures caused by power problems. At the same time, centralized wiring is convenient for management and maintenance, reducing the complexity and maintenance cost of the power supply system and enhancing the operation stability of the entire intelligent pressure regulating equipment.

[0038] In a high-temperature environment, due to the scattered layout of the information collection probes in the sub-control system, if a single probe fails due to the influence of high temperature, it will not cause the interruption of data collection for the entire pipeline section. The fault detection and alarm module of the data collection trolley monitors the temperature of its own electronic components in real time. Once the temperature is too high and approaches the performance threshold, the travel control module drives the trolley to a relatively lower temperature area to take shelter, such as near the shadow of the pipeline. At the same time, if the communication between the sub-control system and the pressure regulating valve unit is unstable due to high temperature, when the information interaction module of the data collection trolley passes by the corresponding sub-control system, it will try to back up data more frequently via Bluetooth to ensure data is not lost.

It reasonably manages the storage space, avoids data redundancy, and ensures the efficient operation of the information storage system. It automatically deletes the data after the data transmission is completed, releases the space, prepares for the next acquisition, and improves the efficiency and orderliness of data processing and storage of the trolley.
