Description

Technical Field

[0001] The utility model relates to the field of pipeline corrosion monitoring, in particular to a novel wireless pipeline corrosion sensor. Background Art

[0002] Currently, due to communication conditions, high monitoring frequency requirements (independent power supply, wireless products are battery-powered), equipment signal shielding, or other historical reasons, traditional pipeline corrosion sensors usually rely on "photoelectric composite cables" or "cables plus network cables" to connect their upstream and downstream wired connections. Specifically, the upstream monitoring terminal is connected to the downstream pipeline corrosion sensor via "photoelectric composite cables" or "cables plus network cables" to achieve the purpose of real-time monitoring of pipeline wall thickness thinning. The advantages and disadvantages of traditional pipeline corrosion sensors are very obvious. Advantages: System stability; Disadvantages: Optical fiber or network cable connection methods will cause signal transmission attenuation as the distance increases, and wired connection methods are greatly limited by spatial location. This makes traditional pipeline corrosion sensors unsuitable for certain specific work environments, such as semi-enclosed spaces, pipelines at 4-8 o'clock, and long-distance pipelines, posing a huge safety hazard to the stable and safe operation of pipelines.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] like Figures 1-8 As shown, the utility model is a new type of wireless pipeline corrosion sensor, including a base 3 and a shell 7 installed on the base 3. A near-field communication system 1, an ultrasonic transducer 2, a processor 4, a micro-electromechanical piezoelectric sensor 5 and a lithium battery 6 are installed in the shell 7. The lithium battery 6 is replaceable, and the capacity of a single cell is ≥3000Ah. The near-field communication system 1, the ultrasonic transducer 2, the processor 4, and the micro-electromechanical piezoelectric sensor 5 are electrically connected to the lithium battery 6 respectively. The lithium battery 6 is used to power the near-field communication system 1, the ultrasonic transducer 2, the processor 4, and the micro-electromechanical piezoelectric sensor 5. The built-in lithium battery 6 can work continuously for more than 10 years. The near-field communication system 1, the ultrasonic transducer 2, and the micro-electromechanical piezoelectric sensor 5 are electrically connected to a processor 4, respectively. The processor 4 is used to control the opening, closing, or operation of the near-field communication system 1, the ultrasonic transducer 2, and the micro-electromechanical piezoelectric sensor 5. At the same time, the processor 4 can simulate the electrical signal and the ultrasonic signal, and apply a temperature compensation algorithm to more accurately obtain the corrosion status of the pipeline wall thickness. The processor 4 can feed back the data collected by the micro-electromechanical piezoelectric sensor 5 to the background controller through the near-field communication system 1. The inherent temperature compensation algorithm and the background controller are both existing technologies and can record and analyze the data transmitted by the processor 4. When the background processor 4 analyzes the data and finds that the data is abnormal, the background controller will issue an alarm to alert the staff. In the description of the present invention, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicating the direction or position relationship, are based on the direction or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0035] The ultrasonic transducer 2 is electrically connected to the micro-electromechanical piezoelectric sensor 5. The ultrasonic transducer 2 converts electrical energy from the lithium battery 6 into ultrasonic waves, which are then supplied to the micro-electromechanical piezoelectric sensor 5. The ultrasonic transducer 2 is equipped with a high-frequency coil and a magnet and is conventional. The micro-electromechanical piezoelectric sensor 5 is a nanoscale, independent, intelligent system. The micro-electromechanical piezoelectric sensor 5 has a self-sleep function, which allows it to automatically wake up and sleep at a set time, saving energy.

[0036] Preferably, the NFC system 1 is wirelessly connected to the backend controller, utilizing a 2.4GHz wireless sensor network or Bluetooth 5.0, with a line-of-sight communication range of ≤350m. When using a 2.4GHz wireless sensor network, data transmission is stable and reliable. When using Bluetooth 5.0, the sensor described herein can be directly connected to a mobile phone, allowing personnel to directly access the mobile phone app to perform equipment inspections using the sensor described herein. Both the mobile phone and the mobile phone app are currently available.

[0037] Preferably, the base 3 is made of epoxy resin; the housing 7 is made of a metal-mixed weather-resistant engineering plastic. Furthermore, the housing 7 has an explosion-proof rating of Ex ia IIC T4 Ga intrinsically safe and an IP67 protection rating. The housing 7 is durable, dustproof, waterproof, shockproof, and corrosion-resistant, making it suitable for harsh industrial environments and highly weather-resistant.

[0038] When monitoring normal-temperature pipelines, apply coupling agent to the lower surface of base 3, then adhere the sensor directly to the outer wall of the pipeline using the coupling agent. Welding can also be used for installation when long-term point monitoring is required or when the equipment is located at a high altitude and cannot be moved. When the sensor is activated, ultrasonic transducer 2 converts the electrical energy provided by lithium battery 6 into ultrasonic waves, which are then supplied to microelectromechanical piezoelectric sensor 5. Microelectromechanical piezoelectric sensor 5 is used to monitor normal-temperature pipelines. Simultaneously, microelectromechanical piezoelectric sensor 5 transmits the collected data to processor 4, which then feeds the data collected by microelectromechanical piezoelectric sensor 5 back to the backend controller via near-field communication system 1.

[0039] When monitoring ultra-high / low temperature pipelines, an expansion monitoring structure is detachably mounted on the lower end of the base 3, and the connection between the utility model and the monitored pipeline is achieved through the expansion monitoring structure.

[0040] Specifically, the expanded monitoring structure includes a temperature probe 8, dual waveguide rods 9, a fixture holder 10, and a fixture (not shown in the accompanying drawings; the fixture is an annular clamp structure that can be fixed around the outside of the pipeline and is conventional). The upper end of the temperature probe 8 passes through the base 3 and is disposed within the housing 7. The upper end of the temperature probe 8 is electrically connected to the microcomputer voltage sensor 5. The fixture holder 10 is installed near the lower end of the dual waveguide rods 9. The fixture holder 10 is detachably mounted with a fixture, and the upper end of the dual waveguide rods 9 is connected to the base 3. The unique dual waveguide rods 9 can effectively isolate the high / low zones of the pipeline being measured and can be used to monitor pipelines with ultra-high (600°C) or ultra-low (-200°C) temperatures.

[0041] Once the sensor with the expanded monitoring structure is in place, the fixture wraps around the outside of the pipe, and the lower ends of the dual waveguide rods 9 and the lower ends of the temperature probe 8 respectively contact the outer wall of the pipe. The sensor is activated, and the ultrasonic transducer 2 converts the electrical energy provided by the lithium battery 6 into ultrasonic waves, which are then supplied to the micro-electromechanical piezoelectric sensor 5. The micro-electromechanical piezoelectric sensor 5 monitors the pipeline via the dual waveguide rods 9 and the temperature probe 8. The temperature probe 8 feeds the collected data back to the micro-electromechanical piezoelectric sensor 5, which then transmits all the data to the processor 4. The processor 4 then feeds the collected data back to the backend controller via the near-field communication system 1.

[0042] This utility model utilizes a sub-invasive ultrasonic sensor installed on the pipe wall and advanced signal processing technology to quickly and accurately determine the corrosion status of the pipe wall by measuring its thickness. A temperature compensation algorithm ensures accurate detection and precise monitoring even under conditions of large temperature fluctuations. Compared to traditional pipeline corrosion sensors, this device offers advantages such as high accuracy, simple installation, and strong weather resistance.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
