Abstract
Description
Technical Field
[0001] The invention relates to the technical field of ultrasonic detection, and in particular to an intelligent wireless ultrasonic detection probe. Background Art
[0002] In the field of industrial non-destructive testing, ultrasonic testing is one of the most widely used technologies, especially in the non-destructive testing of thick-walled pipe welds, where it plays an irreplaceable role. During ultrasonic testing, ultrasonic waves are emitted to the workpiece through a probe. When the ultrasonic waves encounter defects in the workpiece, they form reflected waves, which are then received by the probe and displayed on the ultrasonic detector after being converted into signals. By observing the delay and attenuation of the reflected waves and continuously moving the probe position, the defect situation can be obtained.
[0003] Existing ultrasonic detection methods mainly rely on handheld ultrasonic probes. The probe is equipped with an ultrasonic transmitter and receiver, which transmits ultrasonic waves and receives reflected waves to obtain defect information inside the material. The operator needs to constantly move the probe, observe the reflected wave waveform on the ultrasonic detector screen, and judge the defect situation based on the waveform characteristics. In order to record the location of the defect, the operator usually needs to hold the probe in one hand and a ruler or tape measure in the other hand to measure and manually record the defect information.
[0004] During the implementation process, the inventors found that the above-mentioned prior art has at least the following defects: since the movement position of the ultrasonic probe is greatly affected by the subjective factors of the operator, the movement trajectory of the probe cannot be accurately recorded, which will cause the detected defect position information to be inaccurate. Summary of the invention
[0005] The embodiment of the present application provides an intelligent wireless ultrasonic detection probe, which solves the technical problem in the prior art that the moving position of the ultrasonic probe is greatly affected by the subjective factors of the operator, thereby improving the detection accuracy.
[0006] In order to solve the above technical problems, the present invention adopts the following technical scheme: an intelligent wireless ultrasonic detection probe, which includes a posture sensor module, a probe module, a battery module and an encoder module; wherein the battery module includes a battery and a microprocessor, and the probe module and the encoder module are electrically connected to the microprocessor respectively; the posture sensor module includes a posture sensor, the probe module includes a distance sensor and an ultrasonic probe for detecting defects, and the distance sensor and the ultrasonic probe are both connected to the input end of the microprocessor; the encoder module includes a base, a through hole is provided at the center position of the base, an encoder and a rubber wheel are installed on the base, a ball is installed at the through hole, the outer periphery of the ball can extend out of the through hole and contact with an external workpiece, the outer periphery of the ball is in contact with the outer periphery of the rubber wheel, and the rotating shaft of the rubber wheel is connected to the encoder.
[0007] When inspecting pipeline welds, the attitude sensor can sense the spatial movement angle and rotation angle of the device in real time, and then transmit them to the microprocessor; at the same time, the ball drives the rubber wheel to rotate, and the rubber wheel drives the encoder to rotate, which can record the movement distance of the encoder module. The microprocessor corrects the position by combining the actual displacement data recorded in the encoder and the data in the attitude sensor, which not only improves the detection accuracy, but also improves the detection efficiency.
[0008] Furthermore, the probe module, the battery module and the encoder module are installed at the bottom of the posture sensor module, wherein the battery module and the encoder module are located on one side of the probe module, and the battery module is located above the encoder module.
[0009] Furthermore, the base of the encoder module is square, and encoders are installed at the four corners of the base, and rubber wheels are arranged between two adjacent encoders; when the ball rotates, it can drive the four rubber wheels to rotate at the same time, and the four rubber wheels are respectively connected to encoders, so no matter which direction the ultrasonic probe moves, its moving distance can be recorded by the encoder.
[0010] Furthermore, the middle position of the outer circumferential surface of the rubber wheel is recessed toward the rotation center of the rubber wheel, and the material of the rubber wheel is a soft material.
[0011] Furthermore, the encoder module also includes a spring, which is supported between the battery module and the base of the encoder module; the elasticity of the spring can ensure the stability and flexibility of the connection between the encoder module and the posture sensor module, thereby avoiding jamming or damage caused by hard contact.
[0012] Furthermore, the battery module also includes a button and a Type-C interface, both of which are located on one side of the battery, the output end of the button is electrically connected to the input end of the microprocessor, and the output end of the Type-C interface is electrically connected to the input and output ends of the microprocessor and the input end of the battery; thus, a charger can be connected through the Type-C interface to charge the built-in battery, and the Type-C interface can also be used as a data transmission interface to connect an external ultrasonic detector through the Type-C interface.
[0013] Furthermore, the posture sensor module also includes a screen, and an input end of the screen is electrically connected to an output end of the microprocessor.
[0014] Furthermore, the posture sensor also includes a Bluetooth electronic component, which is electrically connected to the microprocessor in the battery module; thus, an external device, such as an ultrasonic detector, can be connected via the Bluetooth electronic component.
[0015] It can be seen from the above technical solutions that the present invention has at least the following technical effects or advantages: When inspecting pipeline welds, the attitude sensor can sense the spatial movement angle and rotation angle of the device in real time, and then transmit them to the microprocessor; at the same time, the ball drives the rubber wheel to rotate, and the rubber wheel drives the encoder to rotate, which can record the movement distance of the encoder module. The microprocessor corrects the position by combining the actual displacement data recorded in the encoder and the data in the attitude sensor, which not only improves the accuracy but also improves the detection efficiency.

[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.
[0019] The present invention discloses an intelligent wireless ultrasonic detection probe, such as Figure 1As shown, it includes a posture sensor module 4, a probe module 1, a battery module 3 and an encoder module 2. The battery module 3 includes a battery 31 and a microprocessor, and the probe module 1 and the encoder module 2 are electrically connected to the microprocessor respectively.
[0020] The attitude sensor module 4 includes an attitude sensor and a screen. The output end of the attitude sensor is electrically connected to the input end of the microprocessor, and the output end of the microprocessor is electrically connected to the screen and the input end of the Bluetooth electronic component. When detecting the pipeline weld, the spatial motion angle and rotation angle of the device can be sensed in real time by the attitude sensor, and then transmitted to the microprocessor. The data processed by the microprocessor can be displayed on the screen. In addition, the attitude sensor module 4 also includes a Bluetooth electronic component, through which external devices such as ultrasonic detectors can be connected.
[0021] The probe module 1 includes an ultrasonic probe 11 and a distance measuring sensor 12 ( Figure 2 ), the output end of the ultrasonic probe 11 and the output end of the distance sensor 12 are both electrically connected to the input end of the microprocessor. The ultrasonic probe 11 is used to detect defects inside the workpiece. When a workpiece defect is detected, the distance sensor 12 can measure the horizontal distance from the defect to the ultrasonic probe 11, thereby helping to determine the specific position of the defect on the surface of the workpiece.
[0022] The encoder module 2 includes an encoder 23, the output end of which is electrically connected to the input end of the microprocessor, and the moving distance of the device can be recorded through the encoder 23, and then the data is transmitted to the microprocessor. In this way, the microprocessor can correct the position in combination with the actual displacement data recorded in the encoder 23 and the data in the attitude sensor, which not only improves the accuracy, but also improves the detection efficiency.
[0023] like Figure 3 As shown, the probe module 1, the battery module 3 and the encoder module 2 are installed at the bottom of the posture sensor module 4. The battery module 3 and the encoder module 2 are located on one side of the probe module 1, and the battery module 3 is located above the encoder module 2. The encoder module 2 includes a base, and a through hole (not shown in the figure) is provided at the center of the base. A ball 21 is installed at the through hole, and the ball 21 can contact the external workpiece. A rubber wheel 22 and an encoder 23 are also installed on the base. The outer periphery of the rubber wheel 22 contacts the outer periphery of the ball 21, and the rotating shaft of the rubber wheel 22 is connected to the encoder 23. When the device moves close to the surface of the workpiece, the ball 21 rotates, which can drive the rubber wheel to rotate. Since the rotating shaft of the rubber wheel is connected to the encoder 23, the movement length of the ball 21, that is, the movement distance of the device, can be recorded by the encoder 23.
[0024] like Figure 4As shown, the base of the encoder module 2 is square, and encoders 23 are installed at the four corners of the base. Rubber wheels 22 are arranged between two adjacent encoders 23, that is, rubber wheels 22 are arranged near the four edges of the base, and each rubber wheel 22 is connected to an encoder adjacent to it in the clockwise direction. The middle position of the outer circumference of the rubber wheel 22 is concave toward the rotation center of the rubber wheel 22, and the material of the rubber wheel 22 is soft. Therefore, the moving distance of the device forward, backward, left and right can be recorded by the encoder 23, and the curvature when detecting the curved surface can be offset. In addition, the encoder module 2 also includes a spring 24, which is supported between the battery module 3 and the base of the encoder module 2. The elasticity of the spring 24 can ensure the stability and flexibility of the connection between the encoder module 2 and the posture sensor module 4.
[0025] like Figure 5 As shown, the battery module 3 also includes a button 33 and a Type-C interface 32, both of which are located on one side of the battery 31. The output end of the button 33 is electrically connected to the input end of the microprocessor, and the output end of the Type-C interface 32 is electrically connected to the input and output ends of the microprocessor and the input end of the battery 31. Thus, a charger can be connected through the Type-C interface 32 to charge the built-in battery 31, and the Type-C interface 32 can also be used as a data transmission interface to connect an external ultrasonic detector through the Type-C interface 32.
[0026] The working principle of the present invention is: The movement of the probe module 1 drives the ball 21 therein to rotate, and then drives the rubber wheel 22. The rotation of the rubber wheel 22 drives the encoder 23, thereby recording the forward, backward, left and right movement distance of the ultrasonic probe 11. The spatial position of the probe module 1 is obtained by the attitude sensor sensing the spatial motion angle and rotation angle. The corresponding data of the ultrasonic probe 11 on the workpiece detection is processed by the microprocessor and transmitted to the screen of the attitude sensor module 4. When a workpiece defect is detected, the encoder 23 can record the defect length, and the distance sensor 12 can measure the horizontal distance from the defect to the probe. When detecting the pipeline weld, the pipeline diameter can be set to obtain the relevant circumference, and then the defect-related distance can be calculated according to the corresponding angle of the attitude sensor. The present invention is powered by a battery 31, and is provided with a Type-C interface 32 for charging, which can also be used for data transmission. When in use, the Type-C interface 32 is blocked with a rubber plug to prevent the coupling agent from entering and damaging the circuit.
[0027] like Figure 6 As shown, when performing ultrasonic testing, the workflow of the present invention is as follows: First, initialize the program and input the corresponding parameters according to the workpiece to be detected. During the detection process, the ultrasonic probe 11 of the probe module 1 and the posture sensor of the posture sensor module 4 can simultaneously collect signals. When the device moves, the encoder 23 collects information, and at the same time, the screen can be used to determine whether there are defects on the surface of the workpiece. If no defects are found, continue to detect until the detection is completed. If defects are found, the horizontal position of the defect is measured using the distance sensor 12, and then the starting point and end point of the defect are determined in turn, and the position information of the defect is stored or transmitted.
