Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic detection, and in particular to a method for protecting an ultrasonic detection probe. Background Art

[0002] Nondestructive testing is a test method that checks the surface and internal quality of the inspected parts without damaging the workpiece or the working state of the raw materials. The ultrasonic probe transmits ultrasonic waves through a transducer (usually a piezoelectric crystal), and after receiving the reflected ultrasonic waves, it converts them back into electrical signals. This process is repeated between the transmitting and receiving ends of the probe, thus forming continuous ultrasonic scanning and imaging. Controlling the propagation direction of the ultrasonic wave and the degree of energy concentration, when changing the incident angle of the probe or the diffusion angle of the ultrasonic wave, the main energy of the sound wave can be injected into the medium at different angles or the directivity of the sound wave can be changed, thereby improving the resolution, realizing waveform conversion, and controlling the operating frequency.

[0003] During the movement and positioning of the probe, it is easy to lose control or make human errors, causing the probe to continue to move forward and hit the surface of the product. The strong impact can have serious consequences, causing damage to the product and the probe. Ultrasonic probes are highly accurate and expensive, and severe collisions can cause the probe to break and the lens to be damaged.

[0008] However, the above ultrasonic detection probe still has the problem that the probe may be damaged after being hit. Summary of the invention

[0009] In view of the problems existing in the prior art, the present invention provides a method for protecting an ultrasonic detection probe, which converts the vulnerable part of the probe into a brittle material, thereby protecting the probe from force to the greatest extent, thereby solving the problem of damage to the probe when subjected to hard impact.

[0010] To achieve this object, the present invention adopts the following technical solutions:

[0011] The present invention provides a method for protecting an ultrasonic detection probe, the method comprising: selecting a portion of the middle part of a bracket of the ultrasonic detection probe to be connected with a brittle material, and installing an anti-drop chain on the bracket;

[0012] The length of the brittle material accounts for 1 / 4 to 1 / 3 of the total length of the stent.

[0013] The method for protecting the ultrasonic detection probe of the present invention selects a specific length of brittle material connection on the bracket of the ultrasonic detection probe, so that the brittle material breaks after a hard impact, so that the probe is not subjected to force, the damage to the probe caused by the impact is transferred, and the probe is protected. In addition, the brittle material is low in cost and easy to replace after damage. The present invention also adds an anti-drop chain to the bracket to ensure that the chain is protected after the impact, the probe will not fall and be damaged, and will not be impacted by gravity.

[0014] The length of the brittle material of the present invention accounts for 1 / 4 to 1 / 3 of the total length of the bracket, which can not only protect the probe from being damaged after being hit, but also ensure the normal operation of the ultrasonic detection device to the maximum extent. When the length of the brittle material is small, it cannot play a good role in protecting the probe; when the length of the brittle material is large, the ultrasonic detection device cannot work normally.

[0015] The length of the brittle material described in the present invention accounts for 1 / 4 to 1 / 3 of the total length of the stent, for example, it can be 1 / 4, 13 / 50, 7 / 25, 3 / 10, 8 / 25 or 1 / 3, but is not limited to the listed values.

[0020] Preferably, the width of the brittle material is 5 to 8 mm, for example, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm or 8 mm, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0021] The present invention preferably has a width of 5 to 8 mm, which is narrower than the width of the bracket of 15 to 25 mm. In this way, the brittle material has a lower impact strength and breaks after a hard impact, thereby transferring the damage to the probe and protecting the probe.

[0022] Preferably, the length of the brittle material is 10-15 mm, for example, 10 mm, 11 mm, 12 mm, 12.5 mm, 13 mm, 14 mm or 15 mm, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0023] Preferably, the brittle material is snap-connected to the bracket.

[0024] Preferably, the anti-fall chain comprises chain links made of stainless steel.

[0025] Preferably, the chain width of the anti-drop chain is 2 to 3 mm, for example, it can be 2 mm, 2.2 mm, 2.4 mm, 2.5 mm, 2.7 mm, 2.9 mm or 3 mm, but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0026] Preferably, the anti-fall chain is in the form of a cross chain.

[0027] As a preferred technical solution of the present invention, the method comprises:

[0028] A portion of the middle of the stainless steel bracket with a width of 15 to 25 mm of the ultrasonic detection probe is selected and changed into a ceramic buckle connection with a strength of 30 to 120 MPa, and a stainless steel cross chain ring with a chain width of 2 to 3 mm is installed on the bracket;

[0029] The length of the brittle material accounts for 1 / 4 to 1 / 3 of the total length of the stent;

[0030] The brittle material has a width of 5 to 8 mm and a length of 10 to 15 mm.

[0031] Compared with the prior art, the present invention has at least the following beneficial effects:

[0032] The method for protecting the ultrasonic detection probe provided by the present invention uses brittle materials to replace a part of the stainless steel material in the bracket, so that the vulnerable part is converted from the probe to the brittle material, thereby protecting the probe from stress to the greatest extent, and solving the problem of probe damage after the ultrasonic detection device is hit in the prior art.

[0036] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] The present invention provides a method for protecting an ultrasonic detection probe, wherein the structural schematic diagram of the ultrasonic detection device is as follows: Figure 1 shown.

[0038] The method comprises: selecting a portion in the middle of a support 1 of an ultrasonic detection probe 4 to be connected with a brittle material 2 , and installing an anti-drop chain 3 on the support 1 .

[0039] After a hard impact occurs in the ultrasonic detection device, the brittle material 2 breaks, so that the ultrasonic detection probe 4 is not subjected to force, the damage to the ultrasonic detection probe 4 caused by the impact is transferred, and the ultrasonic detection probe 4 is protected.

The present invention also adds an anti-drop chain 3 to the bracket 1 to ensure that the chain is protected after the impact, and the ultrasonic detection probe 4 will not fall and be damaged, and will not be impacted by gravity.

[0040] The length of the brittle material 2 accounts for 1 / 4 to 1 / 3 of the total length of the bracket 1, which can not only protect the ultrasonic detection probe 4 from being damaged after being hit, but also ensure the normal operation of the ultrasonic detection device to the greatest extent.

[0051] The length of the brittle material accounts for 1 / 3 of the total length of the stent;

[0052] The brittle material has a width of 6 mm and a length of 12 mm.

[0056] The length of the brittle material accounts for 1 / 4 to 1 / 3 of the total length of the stent;

[0057] The brittle material has a width of 5 to 8 mm and a length of 10 to 15 mm.
