Description

Technical Field

[0001] The present application relates to the technical field of pipeline detection, and in particular to a leather cup structure of an in-pipeline detection device. Background Art

[0002] Pipelines are important facilities for transporting liquids and gases. They are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. After long-term use, pipelines are prone to varying degrees of damage and deformation, resulting in reduced efficiency of oil and gas transportation. Leakage during transportation leads to increased losses and also poses serious safety hazards. Therefore, it is necessary to conduct regular inspections of pipelines to ensure the integrity of the pipelines and the safety of the surrounding areas, reduce pipeline operation and management risks, and reduce accidents in production operations.

[0003] When performing cleaning and inspection operations in oil and gas pipelines, detectors rely on the pressure difference of the conveying medium to provide power. The power for the detector to move in the pipeline comes from the pressure difference between the fluid in the pipeline and the driving cup, as well as the supporting force that keeps the device roughly in the center of the pipeline.

[0004] In actual use, for some extreme working conditions, such as long distances between transceiver stations (over 300km); harsh environment inside the pipeline (high surface roughness of the pipeline due to severe corrosion, impurities, etc.); some uncoated pipelines with large drops or large terrain undulations, the high running speed and large vibration of the cleaning or detection device during operation in the pipeline will cause severe wear of conventional ordinary leather cups, loss of sealing drive function, and stagnation of the cleaning or detection device in the pipeline, which becomes a difficult problem for cleaning and detection operations in pipelines under complex working conditions. Utility Model Content

[0005] In view of the problem that the leather cup structure in the above-mentioned related art is easy to wear, the present application aims to provide a leather cup structure of an in-pipeline detection device to solve the technical problems existing in the related art.

[0006] To this end, the present application proposes a leather cup structure of an in-pipe detection device, comprising: a main body, having an elastic part; the outer surface of the elastic part is suitable for contacting the inner wall of the pipe; a supporting member, installed on the elastic part and arranged at intervals along the circumference of the elastic part; wherein the supporting member has an arcuate surface, and the arcuate surface contacts the inner wall of the pipe; the supporting member is made of wear-resistant and impact-resistant material.

[0007] In the above technical solution, a supporting member is provided on the surface where the main body contacts the inner wall of the pipe, so that direct contact between the inner wall of the pipe and the main body can be avoided, thereby avoiding friction damage to the main body when moving in the pipe, which helps to improve the reliability of the leather cup structure; at the same time, the surface where the supporting member contacts the inner wall of the pipe is an arc-shaped surface. This design helps to improve the stability of the movement of the leather cup structure; finally, the supporting member is made of wear-resistant and impact-resistant material to ensure that the leather cup structure can be used for a long time in the pipe, thereby reducing the possibility of production accidents and helping to reduce costs.

[0008] In some technical solutions, the outer surface of the elastic portion is optionally provided with mounting grooves spaced apart along the circumference of the elastic portion; the supporting members are fixedly mounted in the mounting grooves. The supporting members are correspondingly mounted in the mounting grooves. This design ensures that the supporting members are tightly and securely mounted on the elastic portion, thereby preventing the supporting members from loosening or falling off during movement of the leather cup structure.

[0009] In some technical solutions, optionally, the arcuate surface is flush with the outer surface of the elastic portion.

[0010] In the above technical solution, the curved surface of the supporting member is flush with the outer surface of the elastic part. In this way, when the leather cup structure moves along the inner wall of the pipe, the supporting member and the elastic part can contact the inner wall of the pipe as a whole, thereby reducing the additional friction caused by height difference or unevenness, helping to reduce wear and extend the service life of the leather cup structure; at the same time, the flush design enables the supporting member to better disperse the pressure of the inner wall of the pipe on the leather cup structure, thereby improving the stability of the leather cup structure in the pipe, which helps to ensure the smooth operation of the detection device in the pipe and reduce errors caused by shaking or tilting.

[0011] In some technical solutions, the support member optionally protrudes from the outer surface of the elastic portion. This design can provide stronger support, thereby helping to maintain the stability and durability of the leather cup structure in complex or harsh environments within the pipeline. At the same time, it can more effectively withstand friction and wear from the inner wall of the pipeline, thereby helping to extend the service life of the leather cup structure and reduce maintenance costs caused by wear.

[0012] In some technical solutions, optionally, the mounting groove includes a first hole and a second hole; the aperture of the first hole is larger than the aperture of the second hole to form a step; the supporting member is installed in the first hole; wherein, the leather cup structure of the in-pipe detection device also includes: a support member, which is arranged in the mounting groove and connected to the supporting member; the support member includes a first section and a second section; the first section is located in the first hole, and the second section is located in the second hole, and partially protrudes from the second hole; the diameter of the cross section of the first section is larger than the aperture of the second hole; a stop member is connected to the support member and is suitable for being operated to selectively prevent or allow the support member to be removed from the mounting groove.

[0013] In the above technical solution, the support member not only serves to further fix the supporting member, but also, because the diameter of the first section is larger than the aperture of the second hole, the support member also serves to prevent the supporting member from falling off from the second hole; at the same time, the stop member makes the supporting member more convenient during installation and disassembly.

[0014] In some technical solutions, at least the portion of the second section protruding from the second hole may optionally be provided with a threaded portion, and the retaining member may be a nut. This connection structure is not only low-cost and readily available, but also simple to operate, allowing installation and removal of the support member without the need for complex tools.

[0015] In some technical solutions, optionally, the wear-resistant and impact-resistant material includes tungsten or a tungsten alloy material.

[0016] In some technical solutions, optionally, the supporting member and the support member are fixed by brazing.

[0017] In some technical solutions, the supporting members are optionally arranged evenly along the circumference of the elastic portion. This arrangement allows the supporting members to form a continuous support structure around the elastic portion, providing uniform support for the cup structure, thereby helping to improve the stability and overall performance of the cup structure.

[0018] In some technical solutions, optionally, the supporting member is spherical.

[0019] Additional aspects and advantages of the present application will become apparent in the following description or may be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0028] The following combination Figures 1 to 3 , the leather cup structure of the in-pipeline detection device provided in the embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0029] like Figures 1 to 3 As shown, an embodiment of the present application provides a leather cup structure of an in-pipeline detection device, which includes: a main body 100 and a supporting member 200.

[0030] Specifically, the body 100 includes an elastic portion 110, the outer surface of which is adapted to contact the inner wall of the pipe. Supporting members 200 are mounted on the elastic portion 110 and spaced apart along the circumference of the elastic portion 110, so that the supporting members 200 contact the inner wall of the pipe. The supporting members 200 have curved surfaces that contact the inner wall of the pipe and are made of a wear-resistant and impact-resistant material.

[0031] In the above embodiment, by arranging the supporting member 200 on the surface where the main body 100 contacts the inner wall of the pipe, direct contact between the inner wall of the pipe and the main body 100 can be avoided, thereby avoiding friction damage to the main body 100 when moving in the pipe, which helps to improve the reliability of the leather cup structure; at the same time, the surface where the supporting member 200 contacts the inner wall of the pipe is an arc-shaped surface. Such a design helps to improve the stability of the movement of the leather cup structure; finally, the supporting member 200 is made of wear-resistant and impact-resistant material to ensure that the leather cup structure can be used for a long time in the pipe, thereby reducing the possibility of production accidents and helping to reduce costs.

[0032] In the above embodiment, the supporting members 200 are evenly arranged along the circumference of the elastic portion 110. This arrangement allows the supporting members 200 to form a continuous support structure around the elastic portion 110, providing uniform support for the leather cup, thereby helping to improve the stability and overall performance of the leather cup structure.

[0033] In some embodiments, the outer surface of the elastic portion 110 (i.e., the surface in contact with the inner wall of the pipe) is provided with mounting grooves 111, which are spaced apart along the circumference of the elastic portion 110. The supporting members 200 are correspondingly mounted in the mounting grooves 111. This ensures that the supporting members 200 are tightly and securely mounted on the elastic portion 110, thereby preventing the supporting members 200 from loosening or falling off during movement of the cup structure.

[0034] In the above embodiment, the curved surface of the support member 200 is flush with the outer surface of the elastic portion 110. This allows the support member 200 and the elastic portion 110 to contact the inner wall of the pipe as a whole when the cup structure moves along the inner wall of the pipe, thereby reducing additional friction caused by height differences or unevenness, helping to reduce wear and extend the service life of the cup structure. Furthermore, the flush design allows the support member 200 to better disperse the pressure of the inner wall of the pipe on the cup structure, thereby improving the stability of the cup structure within the pipe. This helps ensure the smooth operation of the detection device within the pipe and reduces errors caused by shaking or tilting.

[0035] It is understood that in some embodiments, the curved surface of the support member 200 may also slightly protrude from the outer surface of the elastic portion 110. This design can provide a stronger support effect, thereby helping to maintain the stability and durability of the leather cup structure in complex or harsh environments within the pipeline; at the same time, it can more effectively withstand friction and wear on the inner wall of the pipeline, thereby helping to extend the service life of the leather cup structure and reduce maintenance costs caused by wear.

[0036] In practical applications, the supporting member 200 is spherical. The manufacturing of the spherical supporting member 200 is relatively simple and can be achieved by casting, forging or machining.

[0037] In some embodiments, the mounting groove 111 includes a first hole 1111 and a second hole 1112 , and the diameter of the first hole 1111 is larger than that of the second hole 1112 to form a step. The supporting member 200 is installed in the first hole 1111 and cannot pass through the second hole 1112 .

[0038] The leather cup structure also includes a support member 300 and a stop member 400. The support member 300 is disposed in the mounting groove 111 and is connected to the support member 200 to secure the support member 200 in the mounting groove 111. The support member 300 includes a first section 310 and a second section 320. The first section 310 is located in the first hole 1111, and the second section 320 is located in the second hole 1112 and partially protrudes from the second hole 1112; wherein at least the diameter of the first section 310 is larger than the aperture of the second hole 1112. The stop member 400 is connected to the support member 300 and is adapted to be operated to selectively prevent or allow the support member 300 to be removed from the mounting groove 111.

[0039] With this design, the support member 300 not only serves to further fix the supporting member 200, but also prevents the supporting member 200 from falling off from the second hole 1112 because the diameter of the first section 310 is larger than the aperture of the second hole 1112; at the same time, the stop member 400 makes the supporting member 200 more convenient to install and disassemble.

[0040] In some embodiments, at least the portion of the second section 320 protruding from the second hole 1112 is provided with a threaded portion, and accordingly, the stopper 400 is a nut. This connection structure is not only low-cost and readily available, but also simple to operate, and the support member 300 can be installed and removed without complex tools.

[0041] It is understandable that the stopper 400 and the support member 300 may also be connected via a snap-fit ​​structure, but this embodiment is not limited thereto.

[0042] In some embodiments, the wear-resistant and impact-resistant material of the support member 200 includes tungsten or tungsten alloys. Tungsten or tungsten alloys have high hardness, wear resistance, and impact resistance. In addition, they have excellent physical and chemical stability and can adapt to various harsh environments.

[0043] In the above embodiment, the support member 200 and the support member 300 are connected by brazing copper and its copper alloys. Brazed joints made of copper and its copper alloys have high strength and good toughness, and can withstand large loads and impacts. This allows them to maintain good performance under dynamic loads or complex stress conditions, thereby helping to extend the service life of the cup structure.
