Description

Technical Field

[0001] The present application relates to the technical field of nondestructive testing of metal pipelines, and in particular to a sensor probe suitable for pipelines. Background Art

[0002] As an important facility for fluid transmission, the safety and stability of the pipeline system are of great significance to industrial production, energy supply and environmental protection. During the operation of the pipeline system, real-time monitoring of parameters such as temperature, pressure, flow rate, etc. inside the pipeline is the key to ensure safe and efficient operation of the pipeline. In chemical pipeline monitoring, sensors need to face complex environments such as high temperature, high pressure, and corrosive media. Installers also need to face narrow operating environments and complex pipeline structures. Therefore, this places high demands on the structure of the sensor probe and the measurement accuracy.

[0003] There are mainly three types of pipeline monitoring probes in the prior art: 1) Traditional monitoring probes. This type of probe uses a sensing element to sense data changes in the pipeline. The outside of the sensing element is wrapped with a metal corrosion-resistant structure. However, this type of probe needs to be fixed to the pipeline by welding, threaded connection, etc., and sometimes a mounting port needs to be reserved on the pipeline. Therefore, the installation is cumbersome and may damage the pipeline structure; 2) Magnetic sensor probes. This probe can only be used on magnetic materials and may also be affected by factors such as ambient temperature and magnetic field. For example, in an environment of vibration or strong magnetic interference, its stability is low; 3) Adhesive sensor probes. This probe is mainly fixed to the surface of the object to be measured by an adhesive. However, in a high temperature, humid or chemically corrosive environment, the adhesive may gradually age and fail. Aging, falling off or being affected by environmental factors will reduce the measurement accuracy and reliability. At the same time, once this type of probe is pasted and used, it is difficult to remove and reposition it without loss, and it is also difficult to reuse it in different positions.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0020] As an important facility for fluid transmission, the safety and stability of the pipeline system are of great significance to industrial production, energy supply and environmental protection. During the operation of the pipeline system, real-time monitoring of parameters such as temperature, pressure, flow rate, etc. inside the pipeline is the key to ensure safe and efficient operation of the pipeline. In chemical pipeline monitoring, sensors need to face complex environments such as high temperature, high pressure, and corrosive media. Installers also need to face narrow operating environments and complex pipeline structures. Therefore, this places high demands on the structure of the sensor probe and the measurement accuracy.

[0021] There are mainly three types of pipeline monitoring probes in the prior art: 1) Traditional monitoring probes. This type of probe uses a sensing element to sense data changes in the pipeline. The outside of the sensing element is wrapped with a metal corrosion-resistant structure. However, this type of probe needs to be fixed to the pipeline by welding, threaded connection, etc., and sometimes a mounting port needs to be reserved on the pipeline. Therefore, the installation is cumbersome and may damage the pipeline structure; 2) Magnetic sensor probes. This probe can only be used on magnetic materials and may also be affected by factors such as ambient temperature and magnetic field. For example, in an environment of vibration or strong magnetic interference, its stability is low; 3) Adhesive sensor probes. This probe is mainly fixed to the surface of the object to be measured by an adhesive. However, in a high temperature, humid or chemically corrosive environment, the adhesive may gradually age and fail. Aging, falling off or being affected by environmental factors will reduce the measurement accuracy and reliability. At the same time, once this type of probe is pasted and used, it is difficult to remove and reposition it without loss, and it is also difficult to reuse it in different positions.

[0022] Based on this, an exemplary embodiment of the present application provides a sensor probe suitable for a pipeline, the probe includes an outer shell, the outer shell includes an arc portion and a raised portion arranged on the arc portion, and an accommodating space is formed in the raised portion; a permanent magnet is arranged in the accommodating space; a sensor passes through the permanent magnet and is arranged in the accommodating space; a data transmission line is connected to one end of the sensor away from the arc portion; in this way, when installing the sensor probe, only the arc portion needs to be clamped on the measured pipeline, and when the pipeline is magnetic, it can also be assisted in fixing by the magnetic force between the permanent magnet and the pipeline; the probe is not only simple to install, but also easy to remove and change the monitoring position; at the same time, the probe will not cause damage to the pipeline during installation, and non-destructive monitoring can be performed.

[0023] An exemplary embodiment of the present application provides a sensor probe suitable for a pipeline, such as Figure 1 and 2As shown, the sensor probe includes an outer shell 100, a permanent magnet 200, a sensor 300 and a data transmission line 400; the outer shell 100 includes an arc portion 1001 and a protrusion 1002 arranged on the arc portion 1001, the bending radius of the arc portion 1001 is adapted to the bending radius of the pipeline to be monitored, an accommodating space is formed in the protrusion 1002, and a through hole for the data transmission line 400 to pass through is arranged on the top of the protrusion 1002; the permanent magnet 200 is arranged in the accommodating space in the protrusion 1002; the sensor 300 penetrates the permanent magnet 200 and is arranged in the accommodating space; the data transmission line 400 is connected to one end of the sensor 300 away from the arc portion 1001. In this way, when installing the sensor probe, the sensor probe can be fixed by simply using the attraction between the permanent magnet 200 and the pipeline or pressing the protrusion 1002 to clamp the arc portion 1001 on the measured pipeline. At the same time, when the pipeline is magnetic, the magnetic force between the permanent magnet 200 and the pipeline can also be used to assist in fixing. The probe is not only simple to install, but also easy to remove and change the monitoring position. At the same time, the probe will not cause damage to the pipeline during installation, and non-destructive monitoring can be performed.

[0024] The outer shell 100 can protect the sensor 300. Preferably, the outer shell 100 is made of a temperature-resistant and corrosion-resistant material, for example, polytetrafluoroethylene. The arc portion 1001 occupies between 51% and 67% of the entire circle. At this time, it can be better fastened to the pipeline to be tested, thereby increasing the stability of the probe.

[0025] In one embodiment, a temperature-resistant glue is provided on the inner wall of the arc portion 1001. Before installing the sensor probe, the temperature-resistant glue is applied to the inner wall of the arc portion 1001, and then the sensor probe is installed on the pipeline to be tested. The temperature-resistant glue can assist in fixing the sensor probe, making the sensor probe more firmly fixed, thereby improving monitoring stability and accuracy.

[0026] In one embodiment, in order to realize that a sensor probe can monitor multiple directions of the pipeline at the same time, a plurality of protrusions 1002 are provided on the arc portion 1001, and a permanent magnet 200 and a sensor 300 are provided in each of the plurality of protrusions 1002. For example, two, three, four, or five protrusions 1002 may be provided on the outer shell 100, so as to monitor multiple angles and directions of the pipeline to be measured.

[0027] like Figure 3As shown, in an exemplary embodiment, the arc portion 1001 is provided with a first protrusion, a second protrusion and a third protrusion. Depending on the angle and direction to be monitored, the first protrusion, the second protrusion and the third protrusion may have different spacing distances. A first accommodation space is formed in the first protrusion, a second accommodation space is formed in the second protrusion, and a third accommodation space is formed in the third protrusion; a first permanent magnet is provided in the first protrusion, a first sensor is arranged in the first accommodation space through the first permanent magnet, and a first data transmission line is connected to an end of the first sensor away from the arc portion 1001; a second permanent magnet is provided in the second protrusion, a second sensor is arranged in the second accommodation space through the second permanent magnet, and a second data transmission line is connected to an end of the second sensor away from the arc portion 1001; a third permanent magnet is provided in the third protrusion, a third sensor is arranged in the third accommodation space through the third permanent magnet, and a third data transmission line is connected to an end of the third sensor away from the arc portion 1001. In this way, the pipeline to be inspected can be monitored from multiple angles and directions to achieve more comprehensive monitoring, improve the comprehensiveness and efficiency of monitoring, and avoid the complex installation and maintenance caused by installing multiple sensor probes.

[0028] In one embodiment, if Figure 4 As shown, in order to realize full monitoring of the circumferential surface of the pipeline to be measured, connecting parts 500 are respectively provided on the two ends of the arc part 1001, and threaded holes are provided on the connecting parts 500. Two sensor probes are installed on the opposite sides of the pipeline, and the connecting parts 500 of the two sensor probes are aligned. Then, the two connecting parts 500 are fixed together by fasteners, so that the circumferential surface of the pipeline to be measured can be monitored at multiple angles.
