Description

TECHNICAL FIELD

[0001] The application relates to the technical field of nondestructive testing of containers, in particular to a wire arranging and winding device for acoustic emission data lines. BACKGROUND

[0002] In nondestructive testing of pressure vessels or atmospheric pressure vessels, one of the testing methods is acoustic wave testing, and the acoustic wave generating tool is an acoustic emission detector.

[0003] An acoustic emission detector is composed of four parts, namely an acoustic emission sensor, a preamplifier, a data acquisition and processing system and a recording and analysis display system. The principle of the acoustic emission detector is that the sensor in the acoustic emission instrument receives and collects acoustic wave signals, i.e. acoustic emission signals, from the acoustic emission source, the acoustic emission signals are amplified by the preamplifier, and then the acoustic emission signals are processed by the signal acquisition and processing system, and finally the recording and display system records, analyzes and displays the acoustic emission signals to achieve the purpose of detecting the acoustic emission source. All acoustic emission instruments have these four parts, but some of them may combine some parts together, for example, the acoustic emission sensor with a built-in amplifier, the handheld acoustic emission instrument integrating an amplifier, data acquisition and processing and recording and analysis display.

[0004] Working principle of the acoustic emission detector:

[0005] 1) The function of the acoustic emission sensor is to convert the received acoustic emission signals into acoustic emission electrical signals.

[0006] 2) The amplifier connected with the acoustic emission sensor is usually called a preamplifier, and its main function is to amplify or improve the driving ability of the weak acoustic emission electrical signals output by the sensor to become acoustic emission electrical signals that can be transmitted over a long distance and received by the data acquisition system. The preamplifier also often has the functions of an analog signal filter and a calibration acoustic emission signal emitter. According to the form of the data acquisition and processing system, the preamplifier can be built into the sensor or the data acquisition system such as a wireless acoustic emission acquisition module / handheld acoustic emission system, or it can be independently placed between the sensor and the data acquisition system and connected by a cable.

[0007] 3) The data acquisition and processing system usually integrates multiple acquisition cards, each acquisition card has multiple independent channels, and the acquisition cards usually have different models such as 40MHz, 10MHz and 5MHz according to the sampling frequency, and different models such as 18bit and 16bit according to the sampling precision.

[0008] 4) The recording and analysis display system is usually composed of a computer and a special acoustic emission software, and the computer includes a notebook computer and a desktop computer.

[0009] Therefore, in order to realize the above-mentioned technology, signal transmission or data transmission needs to be carried out between the acoustic emission sensor and the data acquisition and processing system, or even between the preamplifier and the data acquisition system, and the commonly used transmission medium is a data line. Since there are many acoustic emission points, usually one acoustic emission detector is equipped with multiple data lines for transmitting signals and data. Especially in the nondestructive testing of large containers, the length of the data line can reach several meters or even tens of meters. Moreover, the data line has the characteristics of softness and elongation, and the nondestructive testing of the container is usually temporary, and the detection equipment needs to be stored and taken away after use. Therefore, some inconvenient problems exist in daily use. One of the most obvious and urgent problems is that the same acoustic emission detector is connected with multiple data lines, and these data lines are easily entangled or knotted during unwinding and arranging and storing, which makes the unwinding and storing process time-consuming and laborious, especially the arranging and storing process. SUMMARY

[0010] Therefore, the purpose of the present application is to provide a line arranging and winding device for acoustic emission data lines, which has the advantages of facilitating the arrangement and storage of data lines and improving efficiency.

[0011] In one aspect of the present application, a line arranging and winding device for acoustic emission data lines is provided, which comprises a flight module, a power module, a communication module, a mounting seat, a controller, and a winding assembly.

[0012] The flight module is electrically connected to the power module, and the power module supplies power to the flight module.

[0013] The flight module and the controller are connected by wireless communication through the communication module.

[0018] The sleeve is fixed on the mounting seat. The power module is electrically connected to the flight driver, and the power module functions for the flight driver. The controller controls the on-off of the power module.

[0019] The acoustic emission data cable winding device described in this application supplies power to the flight module via a power module, enabling the flight module to fly. The control signals of the flight module are transmitted wirelessly via a communication module. The controller communicates wirelessly with the communication module to achieve flight control of the flight module. The flight module and the winding assembly are located at opposite ends of the data cable. The flight module is installed at one end of the data cable, and the winding assembly is installed at the other end. The flight module can straighten the data cable relative to the winding assembly, and it can also fly freely, thereby moving the acoustic emission sensor to any location. Therefore, the acoustic emission data cable winding device of this application can straighten a single data cable and then wind it up in a straight state using the winding assembly, resulting in an easy-to-wind cable. Ultimately, it achieves convenient and easy unwinding and winding of the data cable.

[0022] One end of the connecting rod is fixed to the winding shaft, and the other end is fixedly connected to the guide ring; the connecting rod is placed on one side of the winding roller;

[0023] The winding driver is assembled and connected to the winding shaft, and the winding driver drives the winding shaft to rotate.

[0024] When the winding shaft rotates, the connecting rod causes the guide ring to move around relative to the winding roller.

[0025] The data cable is threaded through the guide ring, and the guide ring drives the data cable to wind around the winding roller.

[0026] Furthermore, the cross-sectional shape of the winding roller is "I" shaped.

[0027] Furthermore, multiple guide rings are provided, and the multiple guide rings are connected and fixed in a row, with each guide ring corresponding to a data line;

[0028] Multiple guide rings are simultaneously driven by the same winding driver to move synchronously around the winding roller.

[0029] Furthermore, the winding assembly also includes an encoder mounted on the winding shaft to record the number of turns wound on the winding shaft;

[0030] The controller is electrically connected to the encoder to receive data signals from the encoder and control the start and stop of the winding driver.

[0031] Furthermore, it also includes a positioning component, which includes a positioning post and a distance sensor;

[0032] The multiple positioning posts are respectively arranged at the inflection points of the polygon;

[0033] The positioning posts are placed vertically; at least two distance sensors are installed at the top of each positioning post; one of the distance sensors on each positioning post is aligned with the other positioning post adjacent to it.

[0034] Furthermore, the mounting base is detachably connected to the acoustic emission sensor.

[0035] Furthermore, four flight modules are mounted on one of the mounting bases, and the four flight modules are installed at the four corners of the mounting base.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0044] See Figures 1-5 This application provides an exemplary cable winding device for acoustic emission data cables, comprising a flight mechanism 90, a controller (not shown), and a winding assembly; the flight mechanism 90 includes a flight module 10, a power module (not shown), a communication module (not shown), and a mounting base 30;

[0045] The flight module 10 is electrically connected to the power module, and the power module supplies power to the flight module 10.

[0046] The flight module 10 and the controller are wirelessly connected via the communication module;

[0047] The flight module 10, the power module, and the communication module are respectively and securely mounted on the mounting base 30;

[0048] The mounting base 30 is installed at the end of the data cable located at the acoustic emission sensor;

[0049] The winding assembly is installed at the end of the data line furthest from the acoustic emission sensor;

[0050] The flight module 10 includes a rotor 11, a flight driver 12, and a sleeve 13; the flight driver 12 is placed inside the sleeve 13, and the rotor 11 is installed at the end of the flight driver 12, and the rotor 11 is driven to rotate by the flight driver 12.

[0051] The sleeve 13 is fixed on the mounting base 30; the power module is electrically connected to the flight driver 12, and the power module powers the flight driver 12; the controller controls the power supply to the power module.

[0052] The acoustic emission data cable winding device described in this application supplies power to the flight module 10 via a power module, enabling the flight module 10 to fly. The control signals of the flight module 10 are transmitted wirelessly via a communication module. The controller communicates wirelessly with the communication module to achieve flight control of the flight module 10. The flight module 10 and the winding assembly are located at opposite ends of the data cable. The flight module 10 is installed at one end of the data cable, and the winding assembly is installed at the other end. This allows the data cable to be straightened relative to the winding assembly via the flight module 10, and the flight module 10 can also fly freely, thereby moving the acoustic emission sensor to any location. Therefore, the acoustic emission data cable winding device of this application can straighten a single data cable and then wind it up via the winding assembly while it is in a straight state, resulting in an easy-to-wind state. Ultimately, it achieves convenient and easy unfolding and winding of the data cable.

[0053] Furthermore, the flight mechanism 90 includes multiple flight modules 10. In the example shown in the attached figure, one flight mechanism 90 is provided with four flight modules 10.

[0054] In some preferred embodiments, the winding assembly includes a winding driver 60, a winding roller 50, a guide ring 41, a connecting rod 42, and a winding shaft 43;

[0055] The winding roller 50 is movably sleeved on the winding shaft 43;

[0056] One end of the connecting rod 42 is fixed to the winding shaft 43, and the other end is fixedly connected to the guide ring 41; the connecting rod 42 is placed on one side of the winding roller 50;

[0057] The winding driver 60 is assembled and connected to the winding shaft 43, and the winding driver 60 drives the winding shaft 43 to rotate.

[0058] When the winding shaft 43 rotates, the connecting rod 42 causes the guide ring 41 to move around relative to the winding roller 50.

[0059] The data cable is threaded through the guide ring 41, and the guide ring 41 drives the data cable to wind around the winding roller 50.

[0060] Furthermore, the winding driver 60 is a drive motor; a circular through hole is formed on the axis of the winding roller 50, and a protective cylinder (not shown in the figure) is installed on the inner wall of the through hole; the winding shaft 43 is sleeved in the protective cylinder;

[0061] The winding assembly also includes a gear transmission box 70, one end of which is fixed with the connecting rod 42, and the other end of which is connected to the transmission gear inside the gear transmission box 70; the gear transmission box 70 is also connected to the winding driver 60, which drives the gear transmission box 70 to rotate, thereby driving the winding shaft 43 to rotate.

[0062] The winding shaft 43 rotates around the protective cylinder, thereby driving the guide ring 41 to rotate around the winding roller 50.

[0063] In some preferred embodiments, a top cover 20 is also included, which is fastened to the mounting base 30 and forms a receiving cavity, in which the power module and the communication module are respectively placed. Thus, the top cover 20 protects the power module and the communication module; the mounting base 30 provides support for the power module and the communication module.

[0064] In some preferred embodiments, the cross-sectional shape of the winding roller 50 is "I" shaped.

[0065] Furthermore, the winding roller 50 is provided with a plurality of partitions 51 to form a plurality of parallel partition receiving grooves B, which are annular in shape.

[0066] In some preferred embodiments, a plurality of guide rings 41 are provided, and the plurality of guide rings 41 are connected and fixed in a row, and each guide ring 41 is connected to a data line.

[0067] Multiple guide rings 41 are simultaneously driven by the same winding driver 60 to move synchronously around the winding roller 50.

[0068] Furthermore, multiple guide rings 41 are provided, and multiple partition receiving slots B are formed. Each guide ring 41 is correspondingly set with a corresponding partition receiving slot B, so that each data line is threaded through a guide ring 41 and each guide ring 41 corresponds to a partition receiving slot B; thereby enabling multiple data lines to be stored and wound relatively independently.

[0069] In some preferred embodiments, the winding assembly further includes an encoder (not shown) mounted on the winding shaft 43 to record the number of turns wound on the winding shaft 43;

[0070] The controller is electrically connected to the encoder to receive data signals from the encoder and control the start and stop of the winding driver 60.

[0071] The encoder can be set to count the number of turns wound and can precisely control the winding driver 60 to stop winding once the winding length is reached.

[0072] In some preferred embodiments, a positioning component is also included, which includes a positioning post and a distance sensor;

[0073] The multiple positioning posts are respectively arranged at the inflection points of the polygon;

[0074] The positioning posts are placed vertically; at least two distance sensors are installed at the top of each positioning post; one of the distance sensors on each positioning post is aligned with the other positioning post adjacent to it.

[0075] In one example, the container under test is a cylindrical storage tank. Four positioning components are installed, each with two distance sensors. In this example, the four positioning posts are arranged in a quadrilateral around the tank. Of the two distance sensors on each post, one is aligned with the next adjacent positioning post to measure the distance between them. The four distance sensors sequentially measure four distances. The other distance sensor on each post is aligned with the outer wall of the tank, and the points aligned with the four distance sensors on the outer wall are different for each of the four sensors. Furthermore, each of the four distance sensors used to measure the distance to the tank rotates around its positioning post, and during this rotation, it measures the minimum distance between the sensor and the tank, thus obtaining the distance between the positioning post and the tank.

[0076] Then, using the four relative distances between the four distance sensors as the side lengths, and the four shortest distances between the positioning column and the storage tank as the basis for drawing the circle of the storage tank, the coordinate position of the outer wall of the storage tank is thus determined in the planar coordinate system.

[0077] Furthermore, based on the position on the outer wall of the storage tank, the controller controls each flight module 10 to fly to a corresponding position set on the outer wall of the storage tank; for example, if there are 6 flight mechanisms 90, then 6 data lines and 6 acoustic emission sensors can be connected, and 6 partitioned receiving slots B are provided. In this example, the circle of the storage tank is divided into six equal parts in the coordinate system, and the 6 flight mechanisms 90 correspond to one of the division points. The controller realizes the automatic flight and control of the flight mechanisms 90, and combined with the coordinates obtained by the positioning component, accurately lands near the designated division point. Then, the acoustic emission sensors are installed on the surface of the storage tank by manual installation for non-destructive acoustic emission detection.

[0078] In other examples, without a positioning component, the coordinates of the coordinate system and the landing point of the flight mechanism 90 can be obtained through drawing. Furthermore, the trajectory and landing point of the flight mechanism 90 can be controlled manually by adjusting the operating parameters within the controller. This manual control method can be referenced from existing drone flight control technologies.

[0079] In the attached diagramFigure 6 The diagram illustrates a principle of distance measurement and positioning based on positioning components. Four positioning components are placed around the perimeter of storage tank C. Positioning posts D1 and D2 are adjacent, and the distance between them is measured and obtained using a distance sensor, resulting in distance L1. The shortest distance between positioning post D1 and storage tank C is denoted as T1. First, four positioning posts are placed on the outside of storage tank C. These four posts can be arranged in a rectangular shape or arbitrarily. Then, the distance sensors on the positioning posts measure the length of the four sides, and the shortest distance from each of the four positioning posts to the storage tank is measured. Finally, the outer diameter and coordinates of the storage tank are measured and calculated. This method is one way to quickly obtain the diameter and coordinates of a storage tank when its outer diameter and coordinates are unknown.

[0080] The non-destructive testing of acoustic emission and the reception of sound waves emitted by acoustic emission sensors are things that can be achieved by existing technologies, and will not be elaborated here.

[0081] In some preferred embodiments, the mounting base 30 is detachably connected to the acoustic emission sensor.

[0082] In some preferred embodiments, the bottom surface of the mounting base 30 is provided with a sleeve ring 31, which is used to attach the acoustic emission sensor. To improve the tightness of the connection, before the acoustic emission sensor is movably attached to the sleeve ring 31, a thickened layer is wrapped around the outer wall of the acoustic emission sensor, so that the connection between the acoustic emission sensor and the sleeve ring 31 is secure.

[0083] In some preferred embodiments, four flight modules 10 are mounted on one of the mounting bases 30, and the four flight modules 10 are mounted at the four corners of the mounting base 30.

[0084] In some preferred embodiments, the two ends of the winding shaft 43 are respectively mounted on the ground via support frames, and the winding driver 60 and the gear transmission box 70 are respectively mounted on the ground via support bases.

[0085] The working principle of the cable management and winding device for acoustic emission data cables in this application is as follows:

[0086] The positioning component is used to determine the selected area, obtain the position and size of the selected area, thereby establishing coordinates and generating them in the system.

[0087] Simultaneously, the positioning component is also used to locate the detected equipment, which is achieved through a distance sensor. For example, the equipment to be detected is a large storage tank with a cylindrical shape.

[0088] The coordinates of the outer contour of the storage tank are then generated in the system, and the locations where acoustic emission sensors need to be placed are also generated.

[0089] Each acoustic emission sensor is numbered, and the sensor number is matched with a location on the tank outline.

[0090] The controller controls the flight component to fly each acoustic emission sensor to a designated location, and the acoustic emission sensors are then manually installed on the outer wall of the storage tank.

[0091] Then, during data cable retrieval, the flight component straightens the data cable, and the winding component retracts and winds it up.

[0092] The cable winding and unwinding device for acoustic emission data cables of this application enables rapid unwinding and rapid cable winding. Moreover, each data cable is independent and will not tangle with each other, which facilitates both testing and winding, making the whole process simple and efficient.

[0093] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
