Problems solved by technology

The first method is poor in installation and cushioning, unstable in structure, and cannot effectively protect the normal operation of the probe. Once the floating disk fails, the entire probe structure will be damaged and the structure is complicated.
The second method has complex structure and high failure rate, mainly because there is no lateral floating function, which leads to poor reliability of detection work
The third method does not apply to oil pipelines

Embodiment approach

[0023] According to an embodiment of the present invention, the base 1 may include a bottom plate 11 and a top plate 12 parallel to each other, and a left side plate 13 and a right side plate 14 connecting the bottom plate 11 and the top plate 12 . The bottom plate 11 , the top plate 12 , the left side plate 13 and the right side plate 14 form a closed quadrilateral structure, and jointly enclose the lower cavity 3 . Since the bottom plate 11 and the top plate 12 are parallel to each other, it can be ensured that the probe 5 installed on the support ring 2 is basically kept parallel to the inner wall of the pipeline, and the best detection effect can be obtained. In addition, when it is compressed, the bottom plate 11 and the top plate 12 that are parallel to each other can also prevent the probe 5 from rotating or twisting and being damaged or affecting the detection effect.

[0024] As an implementation manner, the left side plate 13 is inclined relative to the bottom plate ...

Abstract

The invention provides a probe bracket for an in-pipeline detection device. The probe bracket comprises a base and a supporting ring arranged on the same, wherein the base comprises a lower cavity; the supporting ring comprises an upper cavity; and the lower cavity and the upper cavity can be elastically deformed under pressure and jointly form a two-cavity structure so that the shock-absorbing performance and the structural stability are better. The invention also provides an in-pipeline detection device and a probe structure for the same. The probe structure comprises the probe bracket and a probe fixed on the supporting ring of the probe bracket. By mounting the probe on the probe bracket, the probe is better protected and the working reliability thereof is improved.

Description

technical field [0001] The invention relates to a detection device in a pipeline, which is used for detecting defects in long-distance oil and gas pipelines, such as cracks, corrosion, diameter change and the like. More particularly, the present invention relates to a holder for a probe used in an in-duct detection device, and a probe structure using the same. Background technique [0002] Oil and gas pipeline transportation has become the main means of energy transmission at home and abroad, and in-pipeline inspection has become a recognized pipeline inspection method. The probe brackets of the existing large and medium pipeline internal detection devices mostly adopt the following methods: ① floating plate method, a single buffer probe bracket is installed on the floating plate; ② metal hinge structure; ③ excitation floating structure. The first method is poor in installation and cushioning, unstable in structure, and cannot effectively protect the normal operation of the...
