Description

Technical Field

[0001] The invention relates to the technical field of pipeline monitoring, and in particular to a comprehensive pipeline leakage monitoring device suitable for pipelines with different diameters. Background Art

[0002] Non-destructive testing (NDT) of pipelines is a non-invasive testing method that uses various technical means to evaluate the integrity and performance of pipelines without destroying the pipeline structure. Common pipeline NDT methods include ultrasonic testing (UT), infrared thermal imaging testing (IR), liquid penetrant testing (PT), transient flow testing (TFT) and tracer gas testing (TGT). Ultrasonic testing uses the propagation characteristics of ultrasonic waves in materials to detect internal defects of pipelines by measuring the time difference and intensity of reflected waves. It is suitable for thick-walled pipelines; infrared thermal imaging testing identifies potential defect areas by detecting the temperature distribution difference on the surface of the object. It is easy to operate and suitable for detecting external leaks; liquid penetrant testing uses liquid penetrants to penetrate into surface open defects and displays the location and shape of defects through developers. It is suitable for detecting surface cracks and holes; transient flow testing identifies the leakage location of the pipeline by monitoring the changes in the flow of fluid in the pipeline, and can be tested without stopping the operation; tracer gas testing locates pipeline defects by injecting tracer gas into the pipeline and detecting the gas leakage point. It has high sensitivity and is suitable for low-pressure pipelines. However, these detection technologies also have some disadvantages. First, the test results are easily affected by external environmental factors, such as temperature, humidity, electromagnetic fields, etc., which may lead to deviations in the test results. Secondly, different detection methods are suitable for pipelines of different types and conditions, so it is important to choose the right detection method. In addition, the diameters of pipelines in the project vary, and components of corresponding sizes need to be customized to fix the detection device, which increases the cost and complexity of the detection. At the same time, the interpretation of the test data requires professional knowledge and experience, and incorrect interpretation may lead to misjudgment. Finally, many detection methods require professionals to operate, which requires high skills and experience of the operator, and the training cost is relatively high.

[0003] In summary, the main problem with the current detection technology is that it will be interfered by various influencing factors, causing abnormal detection results. In addition, the pipelines in the project will have different diameters, and components of corresponding sizes need to be customized to fix the detection device. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below.

[0024] Embodiment 1: The present invention adopts the chain structure of a watch, connects two by two through connecting components 1, and increases or decreases components to change the diameter of the device fixing structure to adapt to pipes 6 of different diameters, and finally the device can be firmly fixed on the pipe 6 through the fastening component 5.

[0025] At present, there are many methods for detecting pipeline 6, but they will be interfered by different influencing factors during the monitoring process, which will cause abnormal monitoring results. The present invention combines multiple monitoring methods such as infrared temperature measurement and sound wave monitoring, and sets multiple monitoring devices. Sensors are used to monitor physical factors such as soil temperature and humidity and water flow sound waves in pipeline 6, and collect monitoring data. The data is transmitted to base station 7 through the data line in the transmission pipe, and then compared and processed by the data processor in base station 7. Different monitoring methods determine the safety status of pipeline 6, and upload it to the cloud system through the network for users to view in real time.

[0026] The present invention combines solar panels and sets the base station 7 on the ground. The solar panels absorb solar energy and convert it into electrical energy, which is then used to supply power to various monitoring devices and the processor and networking device in the base station 7 through the wires in the transmission tube, thereby achieving sustainability.

[0027] Specifically, Figure 1 As shown, the comprehensive pipeline leakage monitoring device adapted to different pipe diameters of the present invention comprises a plurality of connecting components 1, and the connecting components 1 are combined into a chain structure by means of end hinges.

[0028] like Figure 2As shown, the connecting member 1 is an arc-shaped sheet structure, a probe hole 103 is set in the center of the connecting member 1, the probe hole 103 runs through, and corresponding sensor fixing holes 102 are set around the probe hole 103. The monitoring device is installed through the sensor fixing hole 102. The monitoring device is equipped with monitoring equipment with different detection technologies, including an infrared temperature measuring device 2, an acoustic wave detection device 3 and a humidity detection device 4. The infrared temperature measuring device 2, the acoustic wave detection device 3 and the humidity detection device 4 are respectively installed on different connecting members 1. The connecting member 1 hinged into a chain structure is wrapped around the pipe 6, and the probes of the infrared temperature measuring device 2, the acoustic wave detection device 3 and the humidity detection device 4 are attached to the outer wall of the pipe 6 through the probe hole 103.

[0029] The infrared temperature measuring device 2 monitors the soil temperature to determine whether the pipeline 6 is leaking; the sound wave detection device 3 collects the sound waves in the pipeline 6 and compares them with normal sound waves to determine whether the pipeline 6 is leaking; the humidity monitoring device monitors the soil humidity to determine whether the pipeline 6 is leaking, etc.

[0030] like Figure 5 As shown, a base station 7 is arranged on the ground, a solar device 8 is arranged on the base station 7, and a data connection is provided between the base station 7 and the monitoring device. The base station 7 is equipped with a data processor, a networking device and a battery. A transmission tube is arranged between the monitoring device and the base station 7, and electric wires and data cables are built in the transmission tube. The monitoring device and the base station 7 are connected by the electric wires and data cables. The transmission tube is made of stainless steel.

[0031] The solar device 8 provides power to the monitoring device and the base station 7 to keep the device working. The base station 7 receives the data collected by the monitoring device and uploads it to the cloud for calculation and comparison. The built-in data processor can process and compare the monitoring data; the networked device uploads the data to the cloud system through the network.

[0032] like Figure 2 and Figure 3 As shown, the connecting member 1 is an arc-shaped plate made of elastic material, for example, a stainless steel spring sheet, two holes are respectively set on both sides of the stainless steel spring sheet, and the ring 101 is installed through the holes. The pipeline leakage comprehensive monitoring device also includes a fastening member 5, which includes two parallel elastic steel wires, and the elastic steel wires are wound into a ring. Figure 4 As shown, a sleeve 501 and a multi-level plug 502 are respectively provided at both ends of the parallel steel wires. The multi-level plug 502 can be inserted into the sleeve 501 to lock the steel wire ring. Rings 101 are installed on both sides of the connecting member 1. The parallel elastic steel wires are respectively inserted into the corresponding rings 101. The connecting member 1 is located in the middle of the two parallel elastic steel wires.

[0033] The elastic steel wire is pressed on the outside of the connecting member 1, and the connecting member 1 and the pipe 6 are tightly fitted together by the elastic steel wire.

[0034] The connecting member 1 itself has a specific length, and simply removing or adding the connecting member 1 cannot always be exactly equal to the circumference of the pipe 6. For example, when the circumference of the pipe 6 is not an integer multiple of the length of the connecting member 1, the chain structure composed of the connecting member 1 cannot fit the outer wall of the pipe 6 tightly.

[0035] The monitoring of the infrared temperature measuring device 2, the sound wave detection device 3 and the humidity detection device 4 depends on the sensors, and the monitoring of the sensors depends on the fit between the sensor probe and the pipe 6, especially the ultrasonic detection sensor. If it cannot fit the wall of the pipe 6, its detection effect will be seriously affected.

[0036] Based on this, the present invention adds a fastening component 5 to the connecting component 1. The fastening component 5 is composed of a complete annular steel wire. When in use, the steel wire is wrapped around the pipe 6, and the steel wire can be tightened according to the size of the pipe 6. The multi-stage plug 502 and the sleeve 501 are inserted into each other to effectively tighten the steel wire so that it is looped around the pipe 6.

[0037] The tightening of the steel wire can compress the elastic arc-shaped plate, so that the arc-shaped plate is bent and pressed against the pipe 6, thereby making the sensor probe close to the pipe 6, thereby improving the accuracy of monitoring.

[0038] like Figure 6 As shown, the present invention also includes a tightening member, which is hinged to the connecting member 1, and the tightening member includes an arc-shaped plate fitted with the pipe 6, and an airbag 9 hole is set in the center of the arc-shaped plate, and the airbag 9 is fixed in the airbag 9 hole. A part of the airbag 9 is located between the arc-shaped plate and the pipe 6, and a part protrudes from the airbag 9 hole. An axle seat is also provided on the outer side surface of the tightening member, and the axle seat is located on one side of the airbag 9 hole. An elastic pressing sheet 10 is installed through the axle seat, and the elastic pressing sheet 10 can rotate around the axle seat. A clamp 11 is provided on the other side of the airbag 9 hole opposite to the axle seat, and the movable end of the elastic pressing sheet 10 is inserted into the clamp 11, so that the elastic pressing sheet 10 can be pressed onto the airbag 9.

[0039] The shape of the tightening member is the same as that of the connecting member 1. A part of the airbag 9 installed on the tightening member is between the member and the pipe 6, and the other part is inflated and exposed. When in use, by pressing the elastic pressing sheet 10, the elastic pressing sheet 10 compresses the exposed part of the airbag 9, and the gas in the airbag 9 flows to the part between the member and the pipe 6 and props it up, so that the connecting member 1 and the pipe 6 fit more closely.

[0040] After the elastic pressing sheet 10 is pressed, its movable end is further inserted into the clamp 11. Due to the elastic external support of the pressing sheet and the limitation of the clamp 11, the flattened pressing sheet can maintain the pressed state in the absence of external force, ensuring that the airbag 9 remains in a supported state, so that the probe on the connecting component 1 can fit the pipe 6 more closely.

[0041] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
