Description

Technical Field

[0001] This utility model relates to the field of testing instruments, and in particular to an ultrasonic reflection type testing instrument. Background Technology

[0002] In industrial inspection, petrochemical, and pipeline monitoring fields, ultrasonic testing technology is widely used for fluid condition monitoring, defect detection, and structural integrity assessment. Traditional ultrasonic testing instruments typically use ultrasonic probes directly for detection. However, this design presents the following technical problems in practical applications:

[0003] First, in certain high-temperature, high-pressure, or highly corrosive environments, directly exposed probes are difficult to operate stably for extended periods, resulting in high maintenance costs. Second, traditional ultrasonic testing instruments are not optimized for the transmission and reflection paths of ultrasonic waves. During signal propagation, factors such as energy attenuation and interference reflection can lead to weak echo signals, affecting the reliability and accuracy of the detection. Furthermore, traditional designs typically do not effectively isolate the ultrasonic probe from the electronic circuitry. The ultrasonic probe generates electromagnetic interference during operation, and the electronic components on the circuit board are highly sensitive to external interference. If the two are not properly isolated, the signal transmission quality may deteriorate, further affecting the detection accuracy. Utility Model Content

[0019] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0020] Example 1

[0021] like Figure 1-3As shown, this utility model is an ultrasonic reflection detector, including a housing 2 connected to a sight glass 1. The sight glass 1 includes a sight glass pipe 13, with a first isolation medium 11 and a second isolation medium 12 symmetrically arranged radially in the sight glass pipe 13. An ultrasonic probe 3 and a circuit board 7 are disposed inside the housing 2. The ultrasonic probe 3 is attached to the first isolation medium 11, and a partition 5 is provided between the ultrasonic probe 3 and the circuit board 7. A through hole 6 is opened on the partition 5. During the detection process, the ultrasonic waves emitted by the ultrasonic probe 3 pass through the first isolation medium 11 and the fluid in the sight glass pipe 13, and are reflected by the second isolation medium 12. The reflected ultrasonic waves pass through the fluid in the sight glass pipe 13 and the first isolation medium 11 again and are received by the ultrasonic probe 3.

[0022] To improve sealing performance, a partition 5 is provided between the ultrasonic probe 3 and the circuit board 7. A through hole 6 is provided on the partition 5. The ultrasonic probe 3 is connected to the circuit board 7 through the through hole 6 via a connecting wire. The through hole 6 is sealed with sealant to improve the reception of ultrasonic waves, prevent ultrasonic waves from affecting the circuit board 7, and enhance the explosion-proof performance of the equipment.

[0023] In this embodiment, a partition 5 is used to separate the ultrasonic probe 3 from the circuit board 7, and a sealing treatment is performed at the through hole 6. By effectively isolating the space between the ultrasonic probe 3 and the circuit board 7, the interference of ultrasonic waves on the electronic components on the circuit board is reduced, thereby achieving the technical effect of improving detection accuracy and enhancing the explosion-proof performance of the equipment. This solves the problems of measurement instability and safety hazards caused by electromagnetic interference and insufficient sealing of traditional ultrasonic testing instruments.

[0024] In this embodiment, the first isolation medium 11 is made of an ultrasonically permeable material, preferably glass.

[0025] In this embodiment, the connection wire and the through hole 6 are sealed with glue to improve the sealing performance, thereby achieving the technical effect of improving the overall protection performance and explosion-proof performance of the equipment.

[0026] Example 2

[0027] This embodiment further illustrates the structure and internal component arrangement of housing 2 based on embodiment 1. Housing 2 consists of a first housing 21, a second housing 22, a third housing 23, and a rear cover 24. One end of the first housing 21 is connected to the sight glass pipe 13, and the other end is connected to the second housing 22. The other end of the second housing 22 is connected to the third housing 23, and the other end of the third housing 23 is connected to the rear cover 24. This structural design facilitates device installation and maintenance while ensuring the stability of signal transmission.

[0028] A first isolation medium 11 is installed at the connection between the first housing 21 and the sight glass pipe 13. A circuit board 7 is installed inside the second housing 22. The ultrasonic probe 3 is electrically connected to the circuit board 7 through a connecting wire. The circuit board 7 is used to receive and process the signals output by the ultrasonic probe 3. A pin header 4 is installed inside the third housing 23 to realize the power supply connection of the detector.

[0029] Furthermore, the first housing 21, the second housing 22, the third housing 23, and the rear cover 24 are all integrally formed from aluminum, which improves the sealing of the equipment connection and makes the detection more stable, thereby improving the detection accuracy, service life, and safety of the equipment. In addition, each component connection is equipped with a sealing ring to ensure the sealing of the connection, improve the stability of the internal electronic components of the equipment, thereby improving the accuracy, explosion-proof performance, and service life of the equipment.

[0030] Example 3

[0031] This embodiment is a further improvement on embodiment 1 or 2. The first isolation medium 11 is coupled to the ultrasonic probe 3 through a coupling agent, which can reduce the energy loss during the propagation of ultrasonic waves.

[0032] By coupling the first isolation medium 11 to the ultrasonic probe 3 with a coupling agent, the propagation interface of ultrasonic waves between the ultrasonic probe 3 and the first isolation medium 11 can be made smoother, reducing the reflection and energy loss of sound waves at the interface, thereby improving the transmission efficiency and signal strength of ultrasonic waves.

[0033] Working principle: The ultrasonic waves emitted by the ultrasonic probe 3 pass through the first isolation medium 11 and the fluid inside the sight glass pipe 13, and are reflected by the second isolation medium 12. The reflected ultrasonic waves pass through the fluid inside the sight glass pipe 13 and the first isolation medium 11, and are received by the ultrasonic probe 3. By using a partition 5 to separate the ultrasonic probe 3 from the circuit board 7 and sealing the through hole 6, the space between the ultrasonic probe 3 and the circuit board 7 is effectively isolated, thereby reducing the interference of ultrasonic waves on the electronic components on the circuit board. This achieves the technical effect of improving detection accuracy and enhancing the explosion-proof performance of the equipment, and solves the problems of measurement instability and safety hazards caused by electromagnetic interference and insufficient sealing in traditional ultrasonic testing instruments.
