Description

Technical Field

[0001] The utility model relates to corrosion detection, in particular to a pipeline corrosion detection box, belonging to the technical field of pipeline detection. Background Art

[0002] Pipeline corrosion refers to the aging of pipelines that transport liquids (such as oil and petroleum products) due to chemical reactions or other reasons. There are many types of corrosion, including oxygen absorption corrosion, bacterial corrosion, sulfur dioxide corrosion, etc. Over time, pipelines will corrode and perforate for a long time, and leaks and other safety accidents will occur, causing safety hazards. Therefore, pipeline corrosion is an important part of pipeline maintenance. Pipeline corrosion detection refers to the detection of metal losses such as pipe wall corrosion in pipelines. It is used to understand the damage of in-service pipelines in the working environment and ensure that defects and damage are detected before serious problems occur in the pipelines.

[0003] A Chinese patent publication (publication number: CN201922258264.8) discloses an ultrasonic corrosion detection device for pressure pipelines, which relates to the field of ultrasonic detection. The ultrasonic corrosion detection device for pressure pipelines includes a detector, a detection fork and a handle. One end of the detector is electrically connected to the handle. The outer surface of the detection fork is provided with a handle. The detection fork includes an arc-shaped member 1, an arc-shaped member 2, a pin shaft, a connecting member, a slideway and a detection frame. The arc-shaped member 1 and the arc-shaped member 2 are rotatably connected by a pin shaft. The outer surface of the pin shaft is rotatably connected with a connecting member at the connection between the arc-shaped member 1 and the arc-shaped member 2. The ultrasonic corrosion detection device for pressure pipelines is provided with an arc-shaped member 1 and an arc-shaped member 2, and the arc-shaped member 1 and the arc-shaped member 2 rotate through the pin shaft. The arc-shaped member 1 and the arc-shaped member 2 rotate to form arc angles of different sizes, which is suitable for detecting pipelines of different diameters and has a wide range of practical applications.

[0004] Although the corrosion detection equipment can adapt to the detection of pipelines with different diameters by rotating the arc-shaped member 1 and the arc-shaped member 2, it is necessary to manually hold the detector with one hand and the detection fork with the other hand to perform corrosion detection on the pipeline during the detection process, which increases the manual workload. In addition, the detector and the detection fork are exposed to the outside world, which may easily cause damage to the detector and the detection fork. Therefore, a pipeline corrosion detection box is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown in Figure 5, an embodiment of the utility model provides a pipeline corrosion detection box, including a box body 1, a detector 2 is placed inside the box body 1, a probe connecting line 3 is fixed and connected to one side of the detector 2, and a detection probe 4 is fixedly connected to the end of the probe connecting line 3 away from the detector 2, a winding shaft 8 is fixedly installed on the bottom of the inner wall of the box body 1, a limiting plate 9 is fixedly installed on the upper end of the winding shaft 8, the probe connecting line 3 is wound around the outside of the winding shaft 8, a storage box 5 is fixedly installed on the bottom of the inner wall of the box body 1, and a support assembly 7 is arranged below the box body 1, and the support assembly 7 includes a rectangular plate 701, a limiting block 702, an anti-slip gasket 703, a rectangular block 704, a ball 705, a connecting rod 706, a spring 707 and a through hole 708.

[0026] In one embodiment, a rectangular block 704 is fixedly installed on the lower surface of the box body 1, and two rectangular plates 701 are fixedly installed on the lower surface of the box body 1. The two rectangular plates 701 are symmetrically arranged, and the rectangular block 704 is located between the two rectangular plates 701. A plurality of connecting rods 706 are fixedly installed on the sides of the two rectangular plates 701 that are close to each other, and the ends of the connecting rods 706 that are close to each other are respectively fixedly connected to the front and rear sides of the rectangular block 704, and a limit block 702 is movably arranged on the outer side of the connecting rod 706. A plurality of springs 707 are fixedly connected on the sides of the two limit blocks 702 that are close to each other, and the ends of the springs 707 that are close to each other are fixedly connected to the front and rear sides of the rectangular block 704. The springs 707 are wound around the outer side of the connecting rod 706, and pipes of different specifications are clamped through two limit blocks 702 with adjustable distances, while providing support force for the box body 1.

[0027] In one embodiment, a through hole 708 is opened on one side of the limit block 702 , and the inner wall of the through hole 708 is in movable contact with the outer side of the connecting rod 706 , so that the limit block 702 slides on the outer side of the connecting rod 706 through the through hole 708 .

[0028] In one embodiment, the side where the two limit blocks 702 are close to each other is arc-shaped, and an anti-skid gasket 703 is fixedly bonded to the side where the two limit blocks 702 are close to each other, thereby increasing the friction between the limit blocks 702 and the pipeline.

[0029] In one embodiment, a plurality of balls 705 are rotatably mounted on the bottom of the rectangular block 704. The arrangement of the plurality of balls 705 facilitates pushing the box 1 outside the pipeline, thereby realizing corrosion detection at different positions of the pipeline.

[0030] In one embodiment, a protective pad 6 is fixedly installed inside the storage box 5 , and the inner wall of the protective pad 6 is in contact with the outer side of the detection probe 4 . The detection probe 4 is protected by the arrangement of the storage box 5 and the protective pad 6 .

[0031] When the utility model is working: the two limit blocks 702 are pulled in opposite directions, so that the limit blocks 702 slide along the connecting rod 706 under the action of the through hole 708, and multiple springs 707 are stretched while the limit blocks 702 move, and the box body 1 is placed above the pipe to be detected, so that multiple balls 705 contact the outside of the pipe. At this time, the pull on the limit blocks 702 is released, and the stretched springs 707 are reset, so that the two limit blocks 702 move along the connecting rod 706 in the direction of approaching each other until the two anti-slip pads 703 contact the outside of the pipe. Under the action of the two limit blocks 702, pipes of different diameters are clamped, and at the same time, a supporting force is provided to the box body 1, so that there is no need to manually hold the detector 2 to perform corrosion detection on the pipe, which reduces the labor of manual work. When corrosion detection is performed on the pipe, the detection probe 4 is removed from the storage box 5. Take it out from the inside, pull the detection probe 4, and separate the probe connecting wire 3 from the winding shaft 8 under the action of the detection probe 4, perform corrosion detection on the pipeline through the detection probe 4, and transmit the detection result to the detector 2 through the probe connecting wire 3, push the box 1, and move the box 1 on the outside of the pipeline under the action of multiple balls 705, and perform corrosion detection on multiple positions of the pipeline. After the detection, wind the probe connecting wire 3 on the outside of the winding shaft 8, and limit the probe connecting wire 3 under the action of the limiting plate 9, and place the detection probe 4 in the storage box 5 at the same time, and protect the detection probe 4 under the action of the protective pad 6, and then pull the box 1 upwards to remove the box 1 from the pipeline, so that it is convenient to store the probe connecting wire 3 and the detection probe 4, and effectively avoid the phenomenon that the probe connecting wire 3 and the detection probe 4 are exposed to the outside for a long time and cause damage.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
