Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection, and in particular to an endoscope-assisted device for detecting pipelines. Background Art

[0002] Pipeline systems (such as oil and gas pipelines, chemical pipelines, municipal water supply and drainage networks, HVAC piping, and shipboard pipelines) play a crucial role in modern industrial production and urban infrastructure maintenance. These pipelines operate in complex environments for long periods of time and are prone to defects (such as cracks, perforations, deformations, and blockages) due to factors such as corrosion, fatigue, mechanical damage, scaling, deposition, and external interference. Timely and accurate detection and location of these defects is crucial for ensuring production safety, preventing leaks, minimizing environmental pollution, reducing maintenance costs, and extending pipeline service life.

The endoscope is fixed by the fastening structure 3 to ensure that the endoscope will not shake or detach from the mounting frame 1 when detecting or moving in the pipeline, thereby improving the stability of the endoscope during the detection process and ensuring the accuracy of the detection results.

[0022] In order to adapt to endoscopes of different specifications and shapes, the fastening structure 3 is an annular structure formed by a number of fasteners 301. Specifically, the several fasteners 301 are arranged along the circumferential direction of the mounting frame 1, and the fasteners 301 are an arc-shaped structure. In this embodiment, three fasteners 301 are arranged at one end of the mounting frame 1, and the three fasteners 301 are arranged along the circumferential direction of the mounting frame 1, so that the three fasteners 301 form an annular structure. The three fasteners 301 are arranged around the endoscope, and the position of each fastener 301 is adjusted by the first adjusting member 302 on the fastener 301, so that each fastener 301 abuts against the endoscope, thereby achieving fixation of the endoscope and adapting to endoscopes of different specifications and shapes.

[0023] In addition, the fastener 301 is made of rubber material, thereby preventing the fastener 301 from causing damage to the endoscope during the fixing process. At the same time, the fastener 301 can also be made of other elastic materials.

[0024] The mounting frame 1 includes a first mounting portion 101, which includes a first fixing ring 1013 and a plurality of first connecting rods 1011 arranged on the first fixing ring 1013. The plurality of first connecting rods 1011 are evenly distributed along the circumferential direction of the first fixing ring 1013, and the first connecting rods 1011 are provided with a first adjustment groove 1012 arranged along the length direction thereof. Furthermore, the first mounting portion 101 is located at the lower end of the mounting frame 1, and the plurality of first connecting rods 1011 are arranged along the axial direction of the first fixing ring 1013, and the plurality of first connecting rods 1011 are all arranged on one side of the first fixing ring 1013. In this embodiment, three first connecting rods 1011 are provided, and a first adjustment groove 1012 is provided on each first connecting rod 1011.

The second mounting portion 102 and the first mounting portion 101 can adjust the distance between the second mounting portion 102 and the first mounting portion 101 by adjusting the relative position of the second connecting rod 1021 and the first connecting rod 1011, thereby adjusting the length of the mounting frame 1.

[0026] Specifically, a second adjusting slot 1022 is provided on the second connecting rod 1021 along its length direction and corresponding to the first adjusting slot 1012. The second adjusting slot 1022 is connected to the corresponding first adjusting slot 1012, and the mounting frame 1 also includes a second adjusting member 103 that is inserted into the first adjusting slot 1012 and the second adjusting slot 1022.

The bolt is inserted into the first adjusting slot 1012 and the second adjusting slot 1022. In the section groove 1012 and the second adjustment groove 1022, the bolts are locked on the first connecting rod 1011 and the second connecting rod 1021 by nuts. When the length of the mounting frame 1 needs to be adjusted, the nuts are loosened and the first mounting part 101 and the second mounting part 102 are moved to change the relative position of the first connecting rod 1011 and the second connecting rod 1021. When the nuts are adjusted to the appropriate position, the nuts are tightened to lock the relative position of the first connecting rod 1011 and the second connecting rod 1021, thereby realizing the adjustment of the position of the mounting frame 1.

[0027] In addition, the second adjusting member 103 is provided with one.

The fastener 301 and the nut are respectively located on the inner and outer sides of the first fixing ring 1013 or the second fixing ring 1023. The bolt is moved by rotating the nut, thereby adjusting the position of the corresponding fastener 301, realizing independent adjustment of several fasteners 301, ensuring that each fastener 301 is in contact with the outer wall of the endoscope, thereby improving the stability of the endoscope installation and meeting the installation requirements of endoscopes of different sizes, specifications and shapes.

[0028] The support structure 2 is hinged on the mounting frame 1, and the two cross-arranged support rods 201 are movably connected to adjust the support distance of the support structure 2, and the two support rods 201 are respectively hinged to the opposite ends of the mounting frame 1. Furthermore, the two cross-arranged support rods 201 are respectively hinged to the outer wall of the first fixing ring 1013 or the second fixing ring 1023, and the two support rods 201 form an X-shaped structure. By adjusting the connection points of the two support rods 201, the angle between the two support rods 201 is changed. When the angle becomes larger, the connection point moves toward the end of the support rod 201 close to the first fixing ring 1013 or the second fixing ring 1023. At this time, the support distance of the support structure 2 is reduced. When the angle becomes smaller, the connection point moves toward the end of the support rod 201 away from the first fixing ring 1013 or the second fixing ring 1023. At this time, the support distance of the support structure 2 is increased, which is suitable for the detection of pipes with various inner diameters.

[0029] Specifically, the support rod 201 is provided with a slide groove 2011 arranged along its length direction, and the slide groove 2011 is provided with a third adjusting member 2012 with a sliding connection, which is used to connect two cross-arranged support rods 201. The slide grooves 2011 of the two cross-arranged support rods 201 are cross-arranged, and the third adjusting member 2012 is connected in the two slide grooves 2011 to form a connection point for connecting the two support rods 201.

[0030] The third adjusting member 2012 is passed through the slide groove 2011 of the two support rods 201 and moves along the slide groove 2011, and the third adjusting member 2012 can lock the two support rods 201 in a relative position. Furthermore, the third adjusting member 2012 is a bolt and a nut, the bolt is passed through the two slide grooves 2011, and the nut is connected to the bolt. By rotating the nut, the bolt can be locked on the support rod 201, and then the two support rods 201 can be locked in a relative position, thereby realizing the locking of the support distance of the support structure 2.

[0031] In this example, three support structures 2 are provided, and the three support structures 2 are evenly distributed along the circumferential direction of the first fixing ring 1013 or the second fixing ring 1023, and the support distance of each support structure 2 can be adjusted independently. Therefore, the support distance of each support structure 2 can be adjusted to adapt to pipes of different shapes, thereby improving the applicability of the auxiliary device.

[0032] In addition, the support distance of the support structure 2 can also be adjusted to be larger at one end and smaller at the other end along the axial direction of the mounting frame 1. Specifically, the third adjusting member 2012 is fixed in the slide groove 2011 of a support rod 201, so that the position of the third adjusting member 2012 in the slide groove 2011 remains unchanged. Then, the support rod 201 is rotated so that the support rod 201 drives the third adjusting member 2012 to move in the slide groove 2011 of the other support rod 201, thereby reducing or increasing the angle between the other support rod 201 and the mounting frame 1. When the angle decreases, the support distance of the other support rod 201 decreases, and when the angle increases, the support distance of the other support rod 201 increases, thereby achieving a support distance of the support structure 2 at one end of the mounting frame 1 that is greater than the support distance at the other end, thereby meeting the detection of pipes with gradually decreasing inner diameters.

[0033] A roller groove 2013 is provided at the end of the support rod 201, and a roller 202 is rotatably connected to the roller groove 2013. Furthermore, the roller groove 2013 is arranged along the length direction of the support rod 201, and the roller 202 is made of rubber material. When the auxiliary device penetrates into the pipeline, the roller 202 abuts against the inner wall of the pipeline, and the roller 202 prevents the support rod 201 from causing damage to the pipeline. In addition, the roller 202 can also be made of other elastic materials.
