[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a..." do not exclude the presence of other identical elements in the process, method, article or device that includes the elements.

[0043] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the embodiments of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0044] Pipelines can be used to transport fluids, gases, or solids. Due to their flexible layout, pipelines are widely used in modern industrial production, various types of mechanical equipment, and daily life. For example, pipelines can be used in power batteries, air conditioning equipment, hydraulic systems, etc. in vehicles.

[0045] According to different application requirements and application scenarios, pipelines often need to be arranged in specific shapes and need to have good airtightness to better realize the transmission of fluids, gases or solids. Therefore, it is often necessary to inspect the behavioral tolerances and airtightness of the pipelines. However, the integration of the inspection equipment in related technologies is poor. The equipment used to inspect the shape and position tolerances of the pipelines and the equipment used to inspect the airtightness of the pipelines are often independent of each other. When inspecting the pipelines, it is often necessary to inspect the shape and position tolerances and airtightness of the pipelines separately, which makes the pipeline inspection process more complicated and is not conducive to improving the inspection efficiency of the pipelines.

[0046] In order to solve the above technical problems, the present application is provided. In order to better understand the present application, the pipeline inspection device of the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0047] Figure 1 This is a schematic diagram of the structure of the pipeline inspection device 1 and the pipeline 2 in some embodiments of the present application. Figure 2 Schematic diagram of an explosion of a pipeline inspection device 1 and a pipeline 2 according to some embodiments of the present application.

[0048] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a pipeline inspection device 1, comprising: a base 11; a first inspection module 12, which is arranged on the base 11, and the first inspection module 12 is provided with an inspection groove 12a for inspecting the form and position tolerances of the pipeline 2; a second inspection module 13, comprising an airtightness tester 131 and a sealing member 132, the sealing member 132 is movably arranged on the base 11 and is used to block one end opening of the pipeline 2 located in the inspection groove 12a, and the airtightness tester 131 is used to connect to the other end opening of the pipeline 2 located in the inspection groove 12a to inspect the airtightness of the pipeline 2.

[0049] An embodiment of the present application provides a pipeline inspection device 1 for inspecting a pipeline 2. The pipeline inspection device 1 includes a base 11, a first inspection module 12, and a second inspection module 13. The first inspection module 12 is disposed on the base 11 and defines an inspection slot 12a for inspecting the form and position tolerances of the pipeline 2. When inspecting the pipeline 2, the form and position tolerances of the pipeline 2 can be inspected by attempting to press the pipeline 2 into the inspection slot 12a. For example, if the pipeline 2 can be pressed into the inspection slot 12a, the form and position tolerances of the pipeline 2 can be considered to be qualified. If the pipeline 2 cannot be pressed into the inspection slot 12a, the form and position tolerances of the pipeline 2 can be considered to be unqualified. The second inspection module 13 includes an airtightness tester 131 and a sealing member 132. The sealing member 132 is movably mounted on the base 11 and can be used to block the opening of the pipeline 2. By positioning the sealing member 132 and the first inspection module 12 on the base 11, the position of the sealing member 132 on the base 11 can be adjusted to adjust the relative position of the inspection slot 12a and the sealing member 132 on the base 11, thereby further inspecting the form and position tolerances of the pipeline 2. When inspecting the pipeline 2, the sealing member 132 can be used to block one end of the pipeline 2, and the airtightness tester 131 can be connected to the other end of the pipeline 2 to inspect the airtightness of the pipeline 2. Therefore, the first inspection module 12 and the second inspection module 13 of the pipeline inspection device 1 can cooperate with each other to realize simultaneous inspection of the form and position tolerances and air tightness of the pipeline 2, so that the pipeline inspection device 1 can better integrate the devices for inspecting the form and position tolerances of the pipeline 2 and the devices for inspecting the air tightness of the pipeline 2 into the base 11, thereby better improving the inspection efficiency of the pipeline 2.

[0050] In an embodiment of the present application, the pipeline inspection device 1 can be used to inspect the form and position tolerances and air tightness of any pipeline 2 used to transport fluids, gases, or solids. Optionally, the pipeline inspection device 1 provided in an embodiment of the present application can be used to inspect pipelines 2 in a vehicle's power battery, air conditioning equipment, or hydraulic system. For example, the pipeline inspection device 1 provided in an embodiment of the present application can be used to inspect the form and position tolerances and air tightness of a liquid cooling pipeline 2 in a power battery.

[0051] Optionally, the base 11 may be provided with a mounting hole 111, a slide groove 112 and other connecting structures for connecting with other devices. The first inspection module 12 and the sealing member 132 may be connected to the base 11 through the connecting structure. The relative position relationship between the connecting structures can be reasonably adjusted to adjust the relative position relationship between the inspection groove 12a in the first inspection module 12 and the sealing member 132 in the second inspection module 13, so as to facilitate the inspection of the relative position relationship between the part of the pipeline 2 located in the inspection groove 12a and the opening blocked by the sealing member 132, thereby realizing the inspection of the form and position tolerance of the pipeline 2.

[0052] Optionally, the number of first inspection modules 12 and blocking components 132 in the pipeline inspection device 1 can be equal. For example, a pipeline inspection device 1 can include N first inspection modules 12 and N blocking components 132, where N can be a positive integer. Optionally, N can be greater than or equal to 2, allowing a pipeline inspection device 1 to simultaneously inspect the geometric and positional tolerances of multiple pipelines 2.

[0053] Optionally, the airtightness tester 131 may include an air tube 131a, which can be used to connect to the opening of the pipeline to test the airtightness of the pipeline. Optionally, the number of airtightness testers 131 in a pipeline inspection device 1 may be only one, and the airtightness tester 131 may include multiple air tubes 131a. When multiple pipelines 2 are placed on a pipeline inspection device 1 to simultaneously test the form and position tolerances of multiple pipelines 2, one airtightness tester 131 can use multiple air tubes to simultaneously test the airtightness of multiple pipelines 2 on the pipeline inspection device 1.

[0054] Optionally, the pipeline inspection device 1 also includes a support pad (not shown in the figure) arranged on the side of the base 11 away from the first inspection module 12, and the support pad can be used to support the base 11, wherein the material of the support pad may include a polymer, and the material of the base 11 may include a metal material.

[0055] In some embodiments of the present application, the shape of the inspection groove 12a can be set according to the shape of the standard pipeline 2, wherein the standard pipeline 2 can refer to a pipeline 2 with an ideal shape. Optionally, the shape of the inspection groove 12a can be the same as or similar to the shape of the standard pipeline 2, so that when inspecting the pipeline 2, the pipeline 2 to be inspected can be tested by attempting to press the pipeline 2 to be inspected into the inspection groove 12a to test the form and position tolerances of the pipeline 2 to be inspected. For example, when the pipeline 2 to be inspected can be pressed into the inspection groove 12a, it can be considered that the shape of the pipeline 2 to be inspected is the same as or similar to the shape of the standard pipeline 2, and the form and position tolerances of the pipeline 2 are qualified. However, when the pipeline 2 to be inspected cannot be pressed into the inspection groove 12a, it can be considered that the shape of the pipeline 2 to be inspected is significantly different from the shape of the standard pipeline 2, and the form and position tolerances of the pipeline 2 are unqualified.

[0056] Optionally, the width of the inspection slot 12a may be slightly larger than the width of the standard pipeline 2. For example, the width of the inspection slot 12a may be 4 mm to 8 mm larger than the width of the standard pipeline 2. The width of the pipeline 2 to be inspected within this error can be considered to be within the qualified range.

[0057] Figure 3 This is a schematic diagram of the structure of the pipeline 2 in some embodiments of the present application. Figure 4 Schematic diagram of the structure of the first profiling block 121, the positioning assembly 122 and the airtightness tester 131 in some embodiments of the present application.

[0058] like Figure 3 and Figure 4 As shown, in some optional embodiments, the first inspection module 12 includes a first profiling block 121 provided on the base 11, and the inspection groove 12a includes a first profiling groove 121a opened on the surface of the first profiling block 121 facing away from the base 11. The first profiling groove 121a is used to accommodate at least a portion of the outer peripheral surface of the quick connector 22 of the pipeline 2 to inspect the shape and position tolerance of the outer peripheral surface of the quick connector 22.

[0059] When inspecting the pipeline 2, the quick connector 22 can be tested for form and position tolerance by attempting to press it into the first contoured groove 121a. Optionally, when the quick connector 22 can be pressed into the first contoured groove 121a, the form and position tolerance of the quick connector 22 can be considered to be acceptable. For example, when the outer peripheral surface of the quick connector 22 can fit the inner surface of the first contoured groove 121a, the form and position tolerance of the outer surface of the quick connector 22 can be considered to be acceptable. However, when the quick connector 22 cannot be pressed into the first contoured groove 121a, the form and position tolerance of the quick connector 22 can be considered to be unacceptable. For example, when the outer peripheral surface of the quick connector 22 cannot fit the inner surface of the first contoured groove 121a, the form and position tolerance of the outer surface of the quick connector 22 can be considered to be unacceptable.

[0060] Optionally, the quick connector 22 of pipeline 2 can be used to connect to other devices to achieve connectivity between the pipe 21 in pipeline 2 and other devices. For example, when pipeline 2 is a liquid cooling pipeline 2 in a power battery of a vehicle, the quick connector 22 of pipeline 2 can be used to connect to the liquid cooling plate in the power battery.

[0061] Optionally, the quick connector 22 includes a connector body 221 and a temperature sensor 222. The connector body 221 can be connected to other devices and has a first opening 2a. When testing the pipeline 2, the airtightness tester 131 can communicate with the pipeline 2 through the first opening 2a on the connector body 221 to test the airtightness of the pipeline 2. The temperature sensor 222 can be used to detect the temperature of the fluid, gas, or solid entering the quick connector 22.

[0062] Optionally, the first contoured groove 121a can be used to accommodate at least a portion of the connector body 221 and / or at least a portion of the temperature sensor 222, so that the first contoured groove 121a can be used to verify the relative positional relationship between the connector body 221 and the temperature sensor 222. When inspecting the pipeline 2, the quick connector 22 can be attempted to be pressed into the first contoured groove 121a to verify the relative positional relationship between the connector body 221 and the temperature sensor 222. When the quick connector 22 can be pressed into the first contoured groove 121a, it can be considered that the relative positional relationship between the connector body 221 and the temperature sensor 222 in the quick connector 22 is correct, that is, the installation position between the connector body 221 and the temperature sensor 222 is correct. When the quick connector 22 cannot be pressed into the first contoured groove 121a, it can be considered that the relative relationship between the connector body 221 and the temperature sensor 222 is incorrect, that is, the installation position between the connector body 221 and the temperature sensor 222 is incorrect, thereby achieving the inspection of the form and position tolerance of the quick connector 22.

[0063] For example, the first contoured groove 121a may only be used to accommodate at least a portion of the connector body 221. When the relative positional relationship between the temperature sensor 222 and the connector body 221 is incorrect, the first contoured groove 121a cannot accommodate both the connector body 221 and the temperature sensor 222 at the same time, making it impossible to press the quick connector 22 into the first contoured groove 121a, thereby enabling the quick connector 22 to be inspected for form and position tolerances.

[0064] Optionally, the first profiling groove 121a may not be used to accommodate the pipe 21 of the pipeline 2, that is, when checking the shape and position tolerances of the quick connector 22, the first profiling block 121 and the first profiling groove 121a may be arranged to bypass the pipe 21 to reduce the interference of the first profiling block 121 on the pipe 21.

[0065] Figure 5 Schematic cross-sectional view of the positioning assembly 122 according to some embodiments of the present application.

[0066] like Figure 4 and Figure 5 As shown, in some optional embodiments, the first inspection module 12 also includes a positioning assembly 122, the positioning assembly 122 includes a positioning sleeve 122a, the positioning sleeve 122a is movably arranged on the base 11 and the axial direction of the positioning sleeve 122a is perpendicular to the upper surface of the base 11, the end of the positioning sleeve 122a facing away from the base 11 is sealed and connected to the airtightness tester 131, the inspection groove 12a includes a second contour groove 1223 opened at one end of the positioning sleeve 122a facing the base 11, the second contour groove 1223 is used to accommodate at least part of the port of the quick connector 22 to inspect the shape and position tolerance of the port of the quick connector 22.

[0067] When inspecting the pipeline 2, the second profiling groove 1223 can be pressed toward the quick connector 22 to attempt to press the port of the quick connector 22 into the second profiling groove 1223 to inspect the form and position tolerances of the port of the quick connector 22. For example, if the port of the quick connector 22 can be pressed into the second profiling groove 1223, it can be considered that the form and position tolerances of the port of the quick connector 22 are qualified. If the port of the quick connector 22 cannot be pressed into the second profiling groove 1223, it can be considered that the form and position tolerances of the port of the quick connector 22 are unqualified.

[0068] Optionally, the positioning sleeve 122a is movably disposed on the base 11, which may mean that the positioning sleeve 122a can be moved relative to the base 11 along its axial direction, so that the positioning sleeve 122a can be moved closer to the base 11 to press the positioning sleeve 122a toward the quick connector 22, thereby enabling detection of the form and position tolerances of the quick connector 22. The positioning sleeve 122a can also be moved away from the base 11 to facilitate placement of the pipeline 2 in the pipeline inspection device 1 or removal of the pipeline 2 from the pipeline inspection device 1.

[0069] Optionally, the positioning sleeve 122a is movably provided on the base 11, which may mean that the positioning sleeve 122a can be moved in a direction parallel to the surface of the base 11, so that the positioning sleeve 122a can be close to or away from the first imitation block 121 provided on the base 11, which can facilitate the alignment between the positioning sleeve 122a and the first imitation block 121, thereby facilitating the inspection of the pipeline 2 by the positioning sleeve 122a.

[0070] Alternatively, the end of the quick connector 22 may refer to the wall portion of the first opening 2a in the quick connector 22. When inspecting the pipeline 2, the second contoured groove 1223 may be pressed against the connector body 221 to attempt to press the wall portion of the connector body 221 surrounding the first opening 2a into the second contoured groove 1223 to inspect the geometric tolerances of the wall portion of the connector body 221 at the first opening 2a.

[0071] If the quick connector 22 fails to meet the required geometric tolerances, for example, if the quick connector 22 cannot be pressed into the second contoured groove 1223, the through hole 1222 may not abut against and communicate with the first opening 2a, and the airtightness tester 131 may not operate. The airtightness tester 131 may only test the airtightness of the pipeline 2 through the through hole 1222 and the first opening 2a when the quick connector 22 meets the required geometric tolerances, that is, when the quick connector 22 can be pressed into the second contoured groove 1223.

[0072] Optionally, the positioning sleeve 122 a may be provided with a conducting hole 1222 for connecting the airtightness tester 131 and the quick connector 22 , and the second contoured groove 1223 may be provided around the conducting hole 1222 .

[0073] In these optional embodiments, when the pipeline inspection device 1 is used to inspect the pipeline 2, the airtightness tester 131 can sequentially communicate with the pipeline 2 through the guide hole 1222 and the first opening 2a located on the quick connector 22 to inspect the airtightness of the pipeline 2. By providing the second profiling groove 1223 surrounding the guide hole 1222 and by properly setting the relative position of the positioning sleeve 122a and the first profiling block 121, when the guide hole 1222 is in communication with the first opening 2a on the quick connector 22, at least a portion of the wall of the first opening 2a can be accommodated in the second profiling groove 1223. That is, the first profiling groove 121a and the second profiling groove 1223 can respectively cooperate with the two side surfaces of the quick connector 22, thereby effectively inspecting the overall form and position tolerances of the quick connector 22.

[0074] like Figure 4 and Figure 5 As shown, in some optional embodiments, the positioning assembly 122 also includes a sleeve bracket 1225 and a first reset member 1226. The sleeve bracket 1225 includes a supporting portion 1225a arranged on the base 11 and a connecting portion 1225b connected to the supporting portion 1225a. The positioning sleeve 122a is movably connected to the connecting portion 1225b. The two ends of the first reset member 1226 are respectively connected to the positioning sleeve 122a and the sleeve bracket 1225. The first reset member 1226 is used to reset the positioning sleeve 122a.

[0075] In this optional embodiment, the positioning sleeve 122a can be pressed toward the first profiling block 121 or moved away from the first profiling block 121 by adjusting the movement of the positioning sleeve 122a relative to the connecting portion 1225b, so as to facilitate the inspection of the shape and position tolerances of the quick connector 22. For example, when inspecting the pipeline 2, the first profiling groove 121a on the first profiling block 121 can be used to accommodate the portion of the quick connector 22 facing the base 11, and the positioning sleeve 122a can be pressed toward the first profiling block 121, so that the second profiling groove 1223 on the positioning sleeve 122a can be used to accommodate the portion of the quick connector 22 facing away from the base 11. As long as the quick connector 22 cannot be pressed into either the first profiling groove 121a or the second profiling groove 1223, it can be considered that the form and position tolerances of the quick connector 22 are incorrect. Only when the quick connector 22 can be pressed into both the first profiling groove 121a and the second profiling groove 1223, can the form and position tolerances of the quick connector 22 be considered correct.

[0076] The first restoring member 1226 can be used to provide a restoring force to the positioning sleeve 122a away from the base 11 when the second profiling groove 1223 partially accommodates the quick connector 22, that is, the restoring force can be used to drive the positioning sleeve 122a to move in a direction away from the base 11, so that when no external force is applied to press the positioning sleeve 122a toward the base 11, there is a certain gap between the positioning sleeve 122a and the first profiling block 121, so that when inspecting the pipeline 2, it is convenient for the operator to try to first press the quick connector 22 of the pipeline 2 into the first profiling groove 121a of the first profiling block 121, and then try to press the positioning sleeve 122a downward to drive the positioning sleeve 122a to press the quick connector 22, so as to realize the inspection of the form and position tolerance of the quick connector 22.

[0077] Optionally, the first restoring member 1226 may be a spring.

[0078] In some optional embodiments, the positioning sleeve 122a includes a connecting tube 1224 and a test head 1221. The test head 1221 can be disposed at the end of the connecting tube 1224 facing the base 11. The guide hole 1222 and the second profiling groove 1223 can be disposed on the side of the test head 1221 facing the base 11.

[0079] Optionally, the connecting tube 1224 includes a connecting wall 1224a and a connecting space 1224b formed by the connecting wall 1224a, and the connecting wall 1224a is provided with a first connecting port 1224c and a second connecting port 1224d connected to the connecting space 1224b. The first connecting port 1224c is located on the side of the connecting space 1224b facing the base 11 and is connected to the conductive hole 1222, and the airtightness tester 131 is connected to the second connecting port 1224d.

[0080] In these optional embodiments, the inspection head 1221 can be connected to the end of the connecting tube 1224 facing the first profiling block 121 to facilitate communication between the guide hole 1222 and the first connection port 1224c. Since the connecting tube 1224 is movable within the guide hole 1225c, the inspection head 1221 can be pressed toward the first profiling block 121 or moved away from the first profiling block 121 by adjusting the movement of the connecting tube 1224 within the guide hole 1225c, thereby facilitating the inspection of the form and position tolerances of the quick connector 22.

[0081] Optionally, the connecting tube 1224 may be shaped as a cylindrical tube, the first connecting port 1224c may be located on the side of the connecting tube 1224 axially facing the base 11 to facilitate communication with the conducting hole 1222, and the second connecting port 1224d may be located on the side of the connecting tube 1224 radially to facilitate communication between the airtightness tester 131 and the second connecting port 1224d.

[0082] Optionally, the connecting tube 1224 also includes a button 1224f arranged on the side of the connecting wall 1224a away from the base 11, one end of the first reset member 1226 can be connected to the side of the connecting portion 1225b away from the base 11, and the other end of the first reset member 1226 can be connected to the side of the button 1224f toward the base 11, and the first reset member 1226 can provide a thrust to the button 1224f away from the base 11.

[0083] Optionally, the connecting wall 1224a may also be provided with a third connecting port 1224e connected to the connecting space 1224b. The third connecting port 1224e may be located on the side of the connecting tube 1224 axially away from the base 11. The button 1224f may be connected to the connecting wall 1224a through the third connecting port 1224e.

[0087] In these optional embodiments, the third profiling groove 123a and the fourth profiling groove 124a can be used to respectively check the form and position tolerances of the pipe 21 and the flange 23 in the pipeline 2. When checking the pipeline 2, the form and position tolerances of the pipe 21 and the flange 23 of the pipeline 2 can be checked by trying to press them into the third profiling groove 123a and the fourth profiling groove 124a respectively.

[0088] Optionally, the fourth profiling groove 124 a may also be used to accommodate a portion of the pipe 21 of the pipeline 2 , so that the fourth profiling groove 124 a may also be used to check the form and position tolerances of the portion of the pipe 21 .

[0089] Optionally, the quick connector 22 and the flange 23 can be located at both ends of the pipe 21, wherein the end of the pipe 21 away from the quick connector 22 can have a second opening 2b, and the sealing member 132 can be used to block the second opening 2b to facilitate the airtightness tester 131 to test the airtightness of the pipeline 2.

[0090] Optionally, on the base 11 , the first profiling block 121 may be disposed adjacent to the second profiling block 123 , so that the first profiling block 121 and the second profiling block 123 can inspect adjacent quick connectors 22 and pipes 21 in the pipeline 2 , respectively.

[0091] Optionally, on the base 11 , the third profiling block 124 may be disposed adjacent to the second profiling block 123 , so that the third profiling block 124 and the second profiling block 123 can inspect the adjacent flange 23 and the pipe 21 in the pipeline 2 , respectively.

[0092] Optionally, on the base 11 , the first profiling block 121 and the third profiling block 124 may be spaced apart so that the first profiling block 121 and the third profiling block 124 can inspect the quick connectors 22 and the flanges 23 at both ends of the pipe 21 , respectively.

[0093] Optionally, the second profiling block 123 can be located between the first profiling block 121 and the third profiling block 124 to facilitate the second profiling block 123 to inspect the pipeline 21, and to facilitate the first profiling block 121 and the third profiling block 124 to inspect the quick connector 22 and the flange 23 at both ends of the pipeline 21 respectively.

[0094] Optionally, the relative position relationship of the positioning assembly 122, the first profiling block 121, the second profiling block 123, the third profiling block 124 and the blocking piece 132 on the base 11 can be reasonably adjusted. For example, the relative position relationship of the sleeve bracket 1225, the first profiling block 121, the second profiling block 123, the third profiling block 124 and the blocking piece 132 on the base 11 can be set according to the shape of the standard pipeline 2, so as to facilitate the inspection of the relative position relationship between the first opening 2a, the second opening 2b, the quick connector 22, the pipe 21 and the flange 23 in the pipeline 2, thereby realizing the inspection of the overall shape and position tolerance of the pipeline 2.

[0095] like Figure 6 and Figure 7As shown, in some optional embodiments, the first inspection module 12 includes a second profiling block 123 arranged on the base 11, the second profiling block 123 includes at least two first sub-profiling blocks 1231, and the inspection groove 12a includes a third profiling groove 123a opened on the surface of the second profiling block 123 facing away from the base 11, the third profiling groove 123a is formed by the first sub-profiling blocks 1231, and the third profiling groove 123a is used to accommodate at least part of the pipe 21 of the pipeline 2 to inspect the shape and position tolerance of the pipe 21.

[0096] Optionally, the first inspection module 12 includes a third profiling block 124 arranged on the base 11, the third profiling block 124 includes at least two second sub-profiling blocks 1241, and the inspection groove 12a includes a fourth profiling groove 124a opened on the surface of the third profiling block 124 facing away from the base 11, the fourth profiling groove 124a is formed by the second sub-profiling blocks 1241, and the fourth profiling groove 124a is used to accommodate at least part of the flange 23 of the pipeline 2 to inspect the shape and position tolerance of the flange 23.

[0097] In this optional embodiment, by setting the third profiling groove 123a to be formed by the first sub-profiling blocks 1231, and setting the fourth profiling groove 124a to be formed by the second sub-profiling blocks 1241, when the pipeline inspection device 1 needs to inspect the pipeline 2 to be inspected with a larger size or a more complex shape structure, that is, when the third profiling groove 123a and the fourth profiling groove 124a in the pipeline inspection device 1 are larger in size or more complex in shape structure, the preparation difficulty of the third profiling groove 123a formed by multiple first sub-profiling blocks 1231 and the fourth profiling groove 124a formed by multiple second sub-profiling blocks 1241 is relatively low, which can facilitate the processing and preparation of the pipeline inspection device 1.

Optionally, each second sub-molding block 1241 can be used to support and accommodate various portions of the flange 23, wherein the shapes of each second sub-molding block 1241 can be the same or different, and the shape of each second sub-molding block 1241 can be set according to the shape of the portion of the flange 23 that it needs to support and accommodate.

[0099] like Figure 7 As shown, in some optional embodiments, the third profiling block 124 is further provided with a through hole 124b communicating with the fourth profiling groove 124a, and the first inspection module 12 further includes a positioning pin 125 movably provided in the through hole 124b.

[0100] Optionally, the flange 23 of the pipeline 2 may have a flange hole 231, and the position of the through hole 124b on the third profiling block 124 may be set based on the position of the flange hole 231 on the flange 23 of the standard pipeline 2 when the flange 23 of the standard pipeline 2 is located in the fourth profiling groove 124a. During pipeline 2 inspection, after the flange 23 can be pressed into the fourth profiling groove 124a, the positioning pin 125 can be pushed within the through hole 124b toward the fourth profiling groove 124a, allowing the positioning pin 125 to move toward the flange 23 within the fourth profiling groove 124a. When the positioning pin 125 can be pressed into the flange hole 231 of the pipeline 2 to be inspected, the form and position tolerances of the flange 23 can be considered qualified. When the positioning pin 125 cannot be pressed into the flange hole 231 of the pipeline 2 to be inspected, the form and position tolerances of the flange 23 can be considered unqualified.

[0101] Optionally, when there are multiple flange holes 231 , the pipeline inspection device 1 may be provided with multiple through holes 124 b and multiple positioning pins 125 to facilitate inspection of the shape and position tolerances of the flange 23 .

For example, the second reset member 126 can be used to provide a reset force to the positioning pin 125 away from the third profiling block 124, that is, the reset force can be used to drive the positioning pin 125 to move in the through hole 124b toward the direction away from the third profiling block 124, so that when no external force is applied to press the positioning pin 125 toward the third profiling block 124, the positioning pin 125 does not occupy too much space in the fourth profiling groove 124a, so that when inspecting the pipeline 2, it is convenient for the operator to try to press the flange 23 of the pipeline 2 into the fourth profiling groove 124a of the third profiling block 124 first.

[0103] Optionally, the second restoring member 126 may be a spring.

[0107] Optionally, the cross-sectional area of ​​the slide groove 112 may gradually decrease in the direction away from the substrate, and the shape of the partial sliding portion 132a located in the slide groove 112 may be adapted to the shape of the slide groove 112, so that when the sliding portion 132a slides into the slide groove 112, the slide groove 112 can provide a limiting effect on the sliding portion 132a, so that the sliding portion 132a is not easily separated from the slide groove 112 in the direction away from the substrate, thereby improving the structural stability of the sliding portion 132a when it cooperates with the slide groove 112.

[0108] Optionally, the material of the plugging head 132b may include rubber or other materials that can be used for plugging and sealing.

When the plugging head 132b is required to block the second opening 2b, the plugging head 132b may be inserted into the second opening 2b to achieve blocking of the second opening 2b. Alternatively, the plugging head 132b may be provided with a blocking cavity 132c. When the plugging head 132b is required to block the second opening 2b, the wall portion of the pipe 21 enclosing the second opening 2b may be inserted into the blocking cavity 132c to achieve blocking of the second opening 2b.

[0110] Optionally, the sleeve bracket 1225, the first profiling block 121, the second profiling block 123, and the third profiling block 124 can be connected to the base 11 through the mounting hole 111.

By setting a positioning block 14 on the base 11, it is possible to facilitate the positioning of the first inspection module 12 and the second inspection module 13 on the base 11. For example, during the assembly process of the pipeline inspection device 1, a three-coordinate measuring machine can be used first to reasonably set the relative positions of the various mounting holes 111 and the slide groove 112 on the base 11 through the positioning hole 141 on the positioning block 14. Then, the first imitation block 121, the second imitation block 123, the third imitation block 124 and the positioning assembly 122 of the first inspection module 12 are assembled to the base 11 through the mounting hole 111, and the sealing piece 132 is assembled to the base 11 through the slide groove 112 to achieve the positioning of the first inspection module 12 and the second inspection module 13. Optionally, after completing the assembly of the first inspection module 12 and the second inspection module 13, the three-coordinate measuring machine can be used again to perform positioning inspection on the relative position relationship of the first inspection module 12 and the second inspection module 13 through the positioning hole 141 on the positioning block 14, so as to realize the inspection of the form and position tolerance of the pipeline inspection device 1 itself.

[0113] Optionally, there may be multiple positioning blocks 14 , and the multiple positioning blocks 14 may be disposed at different positions on the base 11 . For example, the positioning blocks 14 may be disposed at different corners of the base 11 .

[0117] like Figure 10 As shown, in some optional embodiments, the pipeline inspection device 1 further includes a clamping assembly 15 disposed on the side of the base 11 facing the first inspection module 12. The clamping assembly 15 is used to press the pipeline 2 into the inspection groove 12a. For example, the clamping assembly 15 can be used to press the flange 23 into the fourth contoured groove 124a, and can effectively fix the flange 23 in the fourth contoured groove 124a, so as to facilitate the subsequent pressing of the positioning pin 125 into the flange hole 231, thereby facilitating the inspection of the form and position tolerances of the flange 23.

[0118] Optionally, the clamping assembly 15 may include a stand 151, a pressure rod 152, a pressure piece 153, and a wrench 154, wherein the stand 151 may be connected to the base 11 through the mounting hole 111, the pressure rod 152 and the wrench 154 may both be rotatably connected to the stand 151, and the pressure piece 153 may be disposed on the side of the pressure rod 152 facing the base 11. When the clamping assembly 15 is needed to press the pipeline 2 into the inspection groove 12a, the wrench 154 may be pulled to rotate the wrench 154 from a horizontal position to a vertical position relative to the stand 151, so that the wrench 154 can push the pressure rod 152 to rotate toward the base 11, thereby allowing the pressure piece 153 on the pressure rod 152 to press the pipeline 2 into the inspection groove 12a.
