Detailed Description
In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings, which form a part hereof. The accompanying drawings illustrate, by way of example, specific embodiments in which the disclosure can be practiced. The example embodiments are not intended to be exhaustive of all embodiments according to the disclosure. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims.
In view of the deep understanding of the problems existing in the background art, the existing ultrasonic detection device has inaccurate detection results due to the presence of inhomogeneous medium, coupling agent and air bubbles between the ultrasonic probe and the ultrasonic sheath during detection. The invention aims to design an ultrasonic detection auxiliary device which has a simple and compact structure and convenient operation and can remove air bubbles so as to realize clear ultrasonic development and a corresponding ultrasonic detection system.
The sheath device for removing bubbles proposed according to the present disclosure will be described in detail with reference to the accompanying drawings. Wherein fig. 1A shows a schematic view of a sheath device 100 according to one embodiment of the present disclosure.
As can be seen from fig. 1A, the sheath device 100 for removing bubbles proposed according to the present disclosure includes a housing 110, the housing 110 having an inlet 111, the inlet 111 being configured to enable an insertion portion 121 including at least a portion of the ultrasonic detection device 120 to enter into the housing 110. Further, the sheath device 100 further includes a sealing member 115 (not shown in fig. 1A, to be shown in fig. 1B), the sealing member 115 being disposed at the inlet 111 such that a sealing connection can be formed between the insertion part 121 and the accommodation part 110 and such that a chamber 112 (not shown in fig. 1A, to be shown in fig. 1B) is formed between the accommodation part 110 and the insertion part 121, the chamber 112 including a gap where the accommodation part 110 and the insertion part 121 are combined. Here, the sealing member 115 can be configured, for example, as an O-ring seal.
In addition, to eliminate gas in the chamber 112, the sheath device 100 further includes a liquid inlet 113 and a liquid outlet 114 in fluid communication with the chamber 112. Preferably, the sheath device 100 can further include a mounting seat 116, the mounting seat 116 is configured to receive the accommodating portion 110 and form the inlet 111 of the accommodating portion 110, for example, in a snap-fit or screw-fit manner, so that the mounting seat 116 and the accommodating portion 110 are well connected, and here, the liquid inlet 113, the liquid outlet 114 and/or the sealing member 115 can be configured on the mounting seat 116. In this way, the arrangement and fixation of the liquid inlet 113 and the liquid outlet 114 can be facilitated, and also the installation and connection of the pipes can be performed in an easier manner. At this time, in a specific use, the liquid can enter the chamber 112 through the liquid inlet 113, and the gas is discharged out of the chamber 112 through the liquid outlet 114, so that the medium in the chamber 112 is unified, and the development quality is improved.
Further, the sheath device 100 can further include a liquid tank 130, the liquid tank 130 being configured to carry a sealing liquid, such as a couplant. In order to enable the sealing liquid to flow in the chamber 112, the sheath device 100 is further required to include a pipe 131 disposed between the liquid inlet 113 and the liquid tank 130, and a valve 133 configured to control on/off of the fluid in the pipe 131; and a conduit 132 disposed between the liquid outlet 114 and the liquid tank 130, and a valve 134 and an exhaust valve 135 configured to control the on-off of fluid in the conduit 132.
In the sheath device 100 according to the present disclosure, since the liquid inlet 113 and the liquid outlet 114 and the exhaust valve 135 are respectively provided, the gas or air bubbles in the chamber 112 can be removed, and a medium such as a coupling agent is uniformly filled between the insertion portion 121 and the accommodating portion 110, so that the image developed by the ultrasonic detection device is accurate, and the positioning accuracy is improved.
Here, the above-described valves 133, 134 and 135 can be provided as conventional mechanical valves or as solenoid valves, alternatively or additionally. Generally, the density of the coupling agent will be greater than that of the gas, so it is preferable that the liquid inlet 113 is located lower than the liquid outlet 114 in the assembled state of the sheath device 100 and the ultrasonic detection device 120. In this way, the gas in the pipeline can be discharged to a greater extent, and the homogenization of the medium in the pipeline is realized. More preferably, in an assembled state of the sheath device 100 and the ultrasonic detection device 120, the position of the exhaust valve 135 is higher than the position of the liquid outlet 114. Further, since the probe position of the ultrasonic probe needs to be adjusted, the insertion portion 121 is slidably connected to the housing portion 110 via the sealing member 115.
FIG. 1B illustrates a cross-sectional view of the junction of the first receptacle and at least a portion of the ultrasonic testing device in the embodiment of FIG. 1A according to the present disclosure. As can be seen from fig. 1B, the front end of the ultrasonic detection device 120 is not always in a cylindrical shape with a uniform diameter, for example, having the groove 1211 and the groove 1212, so that when the ultrasonic detection device 120 moves to the right in the direction shown in fig. 1B with respect to the housing 110, the groove 1211 and the groove 1212 may exceed the sealing range of the sealing member 115. At this time, the sealing member 115 may not have a good sealing effect, and air bubbles may enter the chamber 112, thereby adversely affecting the development of the ultrasonic detection device 120.
Here, fig. 1C shows a schematic view of an ultrasonic detection device in one embodiment according to the present disclosure. As shown in fig. 1C, at least a portion of the ultrasonic detection device 120 included in the insertion portion 121 includes a first scanning portion (e.g., the position of the slot 1211) and a second scanning portion (e.g., the position of the slot 1212). Preferably, the first scanning section and the second scanning section are perpendicular to each other. The arrangement directions of the first scanning part and the second scanning part are generally perpendicular to each other, so that scanning from different directions is facilitated, and the image quality of scanning imaging is improved.
In order to further improve the air tightness of the sheath device 100 proposed according to the present disclosure, thereby improving the development quality. The inventors of the present disclosure have conceived to add one accommodation portion to achieve this technical object. The sheath device 200 having two housing portions will be described below with reference to fig. 2A and 2B. Wherein fig. 2A shows a schematic view of a sheath device 200 according to another embodiment of the disclosure, and fig. 2B shows a cross-sectional view of a junction of the first receptacle and at least a portion of the ultrasonic detection device in the embodiment of fig. 2A according to the disclosure.
Specifically, as can be seen from fig. 2A, the sheath device 200 proposed according to the present disclosure includes a housing 210, the housing 210 having an entrance (not shown in the figure) configured to enable an insertion portion 221 including at least a portion of the ultrasonic detection device 220 to enter the housing 210. Further, the sheath device 200 further comprises a sealing member 215 (not shown in fig. 2A, which will be shown in fig. 2B), the sealing member 215 being disposed at the inlet so that a sealing connection can be formed between the insertion portion 221 and the accommodation portion 210 and so that a chamber 212 (not shown in fig. 2A, which will be shown in fig. 2B) is formed between the accommodation portion 210 and the insertion portion 221, the chamber 212 including a gap where the accommodation portion 210 and the insertion portion 221 are joined. Here, the sealing member 215 can be configured, for example, as an O-ring seal.
In addition, to eliminate gas in the chamber 212, the sheath device 200 further includes a liquid inlet 213 and a liquid outlet 214 in fluid communication with the chamber 212. Preferably, the sheath device 200 can further comprise a mounting seat 216, the mounting seat 216 is configured to receive the accommodating portion 210 and form an inlet of the accommodating portion 210, for example, in a snap-fit or screw-fit manner, so that the mounting seat 216 and the accommodating portion 210 are well connected, and here, the liquid inlet 213, the liquid outlet 214 and/or the sealing member 215 can be configured on the mounting seat 216. In this way, the arrangement and fixation of the liquid inlet 213 and the liquid outlet 214 can be facilitated, and also the installation and connection of the pipes can be performed in an easier manner. At this time, in a specific use, liquid can enter the chamber 212 through the liquid inlet 213, and gas is discharged out of the chamber 212 through the liquid outlet 214, so that the medium in the chamber 212 is unified, and the development quality is improved.
Further, sheath device 200 can also include a liquid tank 230, the liquid tank 230 configured to carry a sealing liquid, such as a couplant. In order to enable the sealing liquid to flow in the chamber 212, it is further required that the sheath device 200 includes a conduit 231 provided between the liquid inlet 213 and the liquid tank 230, and a valve 233 configured to control on/off of the fluid in the conduit 231; and a conduit 232 disposed between the liquid outlet 214 and the liquid tank 230, and a valve 234 and an exhaust valve 235 configured to control the on-off of fluid in the conduit 232.
In the sheath device 200 according to the present disclosure, since the liquid inlet 213 and the liquid outlet 214 and the exhaust valve 235 are respectively provided, the gas or air bubbles in the chamber 212 can be removed, and a medium such as a coupling agent is uniformly filled between the insertion portion 221 and the accommodation portion 210, so that the image developed by the ultrasonic detection device is accurate, and the positioning accuracy is improved.
Here, the above-described valves 233, 234, and 235 can be provided as either conventional mechanical valves or solenoid valves, alternatively or additionally. Generally, the density of the coupling agent will be greater than that of the gas, so it is preferable that the liquid inlet 213 is located lower than the liquid outlet 214 in the assembled state of the sheath device 200 and the ultrasonic detection device 220. In this way, the gas in the pipeline can be discharged to a greater extent, and the homogenization of the medium in the pipeline is realized. More preferably, in an assembled state of the sheath device 200 and the ultrasonic detection device 220, the position of the exhaust valve 235 is higher than the position of the liquid outlet 214. Further, since the probe position of the ultrasonic probe needs to be adjusted, the insertion portion 221 is slidably connected to the housing portion 210 via the sealing member 215.
FIG. 2B illustrates a cross-sectional view of the connection of the receptacle and at least a portion of the ultrasonic testing device in the embodiment of FIG. 2A according to the present disclosure. As can be seen in fig. 2B, the front end of the ultrasonic testing device 220 is not always a cylinder of uniform diameter, such as having a groove, which may extend beyond the sealing range of the sealing member 215 when the ultrasonic testing device 220 is moved to the left in the direction shown in fig. 2B relative to the housing 210. At this time, the sealing member 215 may not have a good sealing effect, and air bubbles may enter the chamber 212, thereby adversely affecting the development of the ultrasonic detection device 220.
Unlike fig. 1A, 1B, and 1C, the sheath device 200 shown in the embodiment shown in fig. 2A and 2B further includes the following parts, namely: the insertion portion 221 includes another receptacle 250 in addition to at least a portion (e.g., a probe portion) of the ultrasonic testing device 220, the receptacle 250 having an entrance configured to enable at least a portion of the ultrasonic testing device 220 to enter the receptacle 250. In this way, the sealing problem caused by the groove of at least a part of the ultrasonic detection device 220, for example, the ultrasonic scanning portion of the ultrasonic probe portion, can be solved by means of the accommodating portion 250, and thus the developing effect of the sheath device 200 proposed according to the present disclosure is further improved. Here, the receiving portion 250 is preferably configured as a sheath tube having a cylindrical shape.
Furthermore, in order to eliminate gas in a chamber between the housing part 250 and, for example, an ultrasonic probe, the sheath device 200 disclosed according to the present disclosure may further include, for example, a second sealing member 255, the second sealing member 255 being disposed at an inlet of the housing part 250 such that a sealing connection can be formed between at least a portion of the ultrasonic detection device 220 and the housing part 250 and such that a chamber is formed between the housing part 250 and at least a portion of the ultrasonic detection device 220. To exhaust the gas in the chamber, the sheath device 200 can further include a liquid inlet 253 and a liquid outlet 254 in fluid communication with the chamber. At this time, in a specific use, the liquid can enter the chamber through the liquid inlet 253, and the gas is discharged out of the chamber through the liquid outlet 254, so that the medium in the chamber is unified, and the development quality is improved.
To better control the flow of liquid between the liquid tank 230 and the liquid inlet 253 and the liquid outlet 254, the sheath device 200 further comprises a conduit 236 disposed between the liquid inlet 253 and the liquid tank 230 and a valve 238 configured to control the on-off of the fluid in the conduit 236; and a conduit 237 disposed between the liquid outlet 254 and the liquid tank 230, and a valve 239 and an exhaust valve 240 configured to control the on-off of fluid in the conduit 237.
Here, in the sheath device 200 according to the present disclosure, since the liquid inlet 253 and the liquid outlet 254 and the corresponding exhaust valve are provided, gas or bubbles in the chamber between the ultrasonic probe and the accommodating portion 250 can be removed, and a uniform medium is filled between the ultrasonic detection device 220 and the accommodating portion 250, so that an image developed by the ultrasonic detection device 220 is accurate, and the positioning accuracy is improved.
Instead of using a sliding connection between the insertion portion and the receiving portion 210, a fixed connection may be used between the ultrasound probe and the receiving portion 250. For this, the sheath device 200 further includes: a collar 256 and a rubber sealing member 257, the collar 256 and the rubber sealing member 257 being configured for fixedly connecting the housing 250 and the at least one part, such as an ultrasound probe. The housing 250 and at least a portion of the ultrasonic inspection device 220, such as an ultrasonic probe, are fixedly connected in such a manner that the gap between the housing 250 and the ultrasonic probe is not changed, thereby making the filling medium between the housing 250 and the ultrasonic probe uniform. On the other hand, the accommodating part 250 and the ultrasonic probe move together relative to the accommodating part 210, so that the sealing effect is improved. Preferably, in one embodiment according to the present disclosure, the accommodating part 210 and the accommodating part 250 are each configured as a sheath tube having a similar cylindrical shape.
With continued reference to fig. 2A and 2B, the sheath device 200 further includes a first detection unit (not shown in the drawings, for example, inside the first exhaust valve 235) located at the first exhaust valve 235, and the first detection unit is configured to detect a first level of the liquid in the first exhaust valve 235. In addition, the sheath device 200 further includes a control unit (not shown in the drawings, for example, located in the liquid tank 230 or at any position wirelessly connected to the controlled object in the sheath device 200) for controlling the on/off of the first valve 233, the second valve 234, and the first exhaust valve 235. Here, when the first water level is less than a first threshold value, the first valve 233 and the first exhaust valve 235 are opened to exhaust gas in the pipe 231 between the first liquid inlet and the liquid tank 230, the pipe between the first liquid outlet and the first exhaust valve 235, and the chamber 212 between the insert and the sheath 210; when the first water level reaches the first threshold, which is lower than the second threshold, indicating that the aforementioned part of the gas has been discharged, the first valve 233 is closed and the second valve 234 is opened to discharge the gas in the pipe between the liquid tank 230 and the first exhaust valve 235, and when the first water level reaches the second threshold, which is lower than the second threshold, indicating that the gas in the pipe between the liquid tank 230 and the first exhaust valve 235 has been discharged, the first exhaust valve 235 is closed and the first valve 233 is opened. At this time, the sheath device 200 can be normally operated.
In order to further exhaust the gas between the ultrasonic probe and another sheath tube 250, the sheath device 200 can further include: a second detecting unit (not shown in the figure, for example, inside the second exhaust valve 240) located at the second exhaust valve 240, for detecting a second water level at the second exhaust valve 240. In addition, the sheath device 200 can further include another control unit (not shown in the drawings, for example, located in the liquid tank 230 or at any position wirelessly connected to the controlled object in the sheath device 200) for controlling the on/off of the third valve 238, the fourth valve 239, and the second exhaust valve 240. Here, when the second water level is less than the first threshold, the third valve 238 and the second vent valve 240 are opened to vent gas from the conduit 236 between the second liquid inlet and the liquid tank 230, the conduit between the second liquid outlet and the second vent valve 240, and the chamber between the ultrasonic probe and the internal sheath 250; when the second water level reaches the first threshold, indicating that the previously mentioned part of the gas has been evacuated, the third valve 238 is closed and the fourth valve 239 is opened to evacuate the gas in the conduit between the liquid tank 230 and the second exhaust valve 240, and when the second water level reaches the second threshold, indicating that the gas in the conduit between the liquid tank 230 and the second exhaust valve 240 has been evacuated, the second exhaust valve 240 and the fourth valve 239 are closed, wherein the first threshold is smaller than the second threshold. At this time, the sheath device 200 can be operated normally.
When in specific use, the head of the ultrasonic probe can be inserted into the inner sheath tube of the accommodating part 250 for a certain distance, so that two scanning parts of the ultrasonic probe completely enter the inner sheath tube, and then the ultrasonic probe and the inner sheath tube are statically sealed through a hoop and a rubber sealing sleeve. Then, liquid is injected into the cavity between the ultrasonic probe and the inner sheath tube by virtue of the pipeline and the valve which are matched with the inner sheath tube, and gas is discharged, and then the ultrasonic probe and the inner sheath tube are fixedly connected, so that the matched valve can be closed, and only the gap between the ultrasonic probe and the inner sheath tube is filled with liquid with good fluidity. In contrast, although the gap between the inner sheath and the outer sheath of the accommodating portion 210 is filled with the liquid having good fluidity, the inner sheath and the outer sheath need to be slidably connected, and therefore, although the liquid filling process and the gas discharging process are the same, in particular, the valve associated therewith needs to be in an open state so that the liquid can flow between the chamber and the liquid tank as the chamber is increased or decreased. In addition, the ultrasonic probe and the inner sheath can move together, and can move and rotate in the outer sheath, so that clear ultrasonic development can be realized.
Furthermore, a second aspect of the present disclosure proposes an ultrasonic inspection system comprising: an ultrasound detection device 120 or 220 and a sheath device 100 or 200 as disclosed according to the first aspect of the present disclosure.
In summary, in the sheath device provided in accordance with the present disclosure, the first liquid inlet and the first liquid outlet and the corresponding first exhaust valve are provided, so that the gas or the bubbles in the first chamber can be exhausted, and the uniform medium is filled between the insertion portion and the first accommodating portion, so that the image developed by the ultrasonic detection device is accurate, and the positioning accuracy is improved.
While various exemplary embodiments of the disclosure have been described, it will be apparent to those skilled in the art that various changes and modifications can be made which will achieve one or more of the advantages of the disclosure without departing from the spirit and scope of the disclosure. Other components performing the same function may be substituted as appropriate by those skilled in the art. It should be understood that features explained herein with reference to a particular figure may be combined with features of other figures, even in those cases where this is not explicitly mentioned. Further, the methods of the present disclosure may be implemented in either all software implementations using appropriate processor instructions or hybrid implementations using a combination of hardware logic and software logic to achieve the same result. Such modifications to the solution according to the disclosure are intended to be covered by the appended claims.
