Description

Technical Field

[0001] The utility model relates to the technical field of in-pipeline detection, in particular to a sealing plate structure of an in-pipeline detector. Background Art

[0002] Pipelines are the most effective way to transport hazardous liquids and gases. However, due to age, internal defects, or lack of maintenance, pipelines can leak. Long-term corrosion can cause pipe wall thinning, making the production process quite dangerous. Ferromagnetic materials are currently used in all aspects of life, including factories, automobiles, ships, oil and gas pipelines, and the petroleum and petrochemical industries. Ensuring their safety is crucial.

[0003] In order to extend the life of pipelines and prevent accidents, it is very important to conduct effective inspection and maintenance of pipelines. Detectors have emerged as the times require. They can travel in pipelines and have functions such as information collection, data processing and storage. In most cases, pipeline detectors can conduct in-pipeline inspections without affecting pipeline operation, and can effectively and accurately detect pipeline conditions.

[0004] The in-pipeline detector device is the part that operates within the pipeline and is generally divided into four sections: the power section, the measurement section, the computer section, and the battery section. Each section has its own function and role, and must operate smoothly within the pipeline to ensure the proper function of the detection device. Some electrical components within the in-pipeline detector device are not waterproof. If pipeline media enters the working section, it could cause a short circuit and damage the in-pipeline detector device. Some pipeline media are also corrosive, and direct contact with internal components of the working section can corrode the structure and prevent proper detection. Summary of the Invention

[0005] The purpose of the utility model is to provide a sealing plate structure of an in-pipe detector, aiming to solve the problem of lack of protection of the existing in-pipe detector.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A sealing plate structure for a detector in a pipeline, comprising:

[0008] The fixed base is annular and attached to the inner wall of the pipe;

[0009] The blocking plate is arranged on the inner ring of the fixed base and extends along the axis direction of the fixed base;

[0010] The traction probe is arranged on one side of the extending direction of the blocking plate, and the traction probe, the blocking plate and the fixed base are coaxially arranged, and the cross section is stepped.

[0011] Furthermore, the traction probe is in a frustum shape, and a traction hole perpendicular to the axis direction is opened in the middle.

[0012] Furthermore, the blocking plate is disc-shaped, with two wiring holes provided on the blocking plate, and an annular connecting groove provided on the bottom of the side surface of the blocking plate.

[0013] Furthermore, a plurality of screw holes are evenly spaced circumferentially on the fixing base.

[0014] The technical solution adopted by the utility model has the following beneficial effects:

[0015] In this application, by providing a pulling point for the in-pipe detector, it is convenient to remove the in-pipe detector from the tested pipeline at the end of the test. During the detection process, the resistance generated by the in-pipe detector to the pipeline medium during operation is reduced, and the pipeline medium is effectively prevented from entering the structure of the in-pipe detector and contacting the internal circuit components, and has good sealing and blocking properties. During the detection process, the in-pipe detector is effectively protected to prevent the in-pipe detector from short-circuiting due to water ingress and malfunctioning. The overall structure has strong stability, a relatively simple structure, and is economical and affordable, achieving a blocking effect on the in-pipe detector. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and effect of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] In this embodiment, see Figure 1-Figure 3A sealing plate 2 structure of an in-pipe detector includes a fixed base 3, which is annular and attached to the inner wall of the pipe; the sealing plate 2 is arranged on the inner ring of the fixed base 3 and extends along the axial direction of the fixed base 3; the traction probe 1 is arranged on one side of the extension direction of the sealing plate 2, and the traction probe 1, the sealing plate 2 and the fixed base 3 are coaxially arranged, and the cross-section is stepped.

[0022] It should be noted that, see Figure 3 The traction probe 1 is truncated in shape, with a traction hole 4 defined in its center, perpendicular to the axial direction. The traction probe 1 is constructed of a truncated cone with a cylindrical body of equal diameter. Made of stainless steel, which offers excellent hardness and strength, the traction probe 1's shape effectively reduces the resistance generated by the in-pipe detector during testing. A traction hole 4 runs through the side of the traction probe 1, allowing a steel wire rope to pull the in-pipe detector through the circular hole and remove it from the pipeline.

[0023] In addition, when in use, the traction line can be passed through the traction hole 4, and then the traction line can be pulled to pull the sealing plate 2 to move in the pipeline, so that the pipeline is sealed as a whole, and the medium or impurities in the pipeline can be pulled out of the pipeline during the pulling process, so that the detector will not be affected by the large amount of water quality or impurities in the pipeline during operation, thereby ensuring the normal operation of the detector.

[0024] In the embodiment of the present invention, see Figure 1 and Figure 2 The blocking plate 2 is disc-shaped, with two wiring holes 5 provided on the blocking plate 2, and an annular connecting groove 7 provided on the bottom of the side of the blocking plate 2. The blocking plate 2 is a disc-shaped structure made of stainless steel, with excellent sealing and waterproof properties, isolating the internal components from the external pipeline medium. There are two wiring holes 5 on the upper surface of the blocking plate 2 for the sensor signal line to pass through and fix, to prevent the signal line from being squeezed, worn or pulled off. The boundaries of the wiring holes 5 are chamfered to protect the signal line to the greatest extent. At the same time, a waterproof connector can be connected in the wiring hole 5 to further ensure the sealing. The center of the circle on the upper surface of the blocking plate 2 is connected to the traction probe 1, and the bottom of the disc wall of the blocking plate 2 is connected to the fixed base 3. There is an annular connecting groove 7 at the bottom of the side of the blocking plate 2, so that the detector inside the pipeline and the blocking plate 2 structure of the detector inside the pipeline are connected and fixed.

[0025] In this embodiment, see Figure 1 and Figure 2The fixed base 3 is a circular metal plate made of stainless steel. It connects to the sealing plate 2 at right angles. Its inner diameter is equal to its outer diameter, ensuring a tight seal between the detector and the sealing plate 2. Eight screw holes 6 are symmetrically distributed around the center of the fixed base 3. Screws pass through these holes to secure the detector to the pipeline. This ensures a stable connection between the detector and the sealing plate 2, prevents media from passing through the sealing plate 2 and contacting the detector, and reduces detector failure rates.

[0026] In the embodiment of the present invention, the existing detector structure is generally divided into four sections (power section, measurement section, computer section and battery section). Combined with the sealing plate 2 structure of the present application, the two ends of each section can be connected and fixed to the sealing plate 2 structure according to the above method, and the sections are then connected by the iron chain on the traction probe 1. In this way, the sealing and waterproof properties of each section can be guaranteed, and the overall waterproof sealing performance of the internal detection device is significantly improved; the present invention protects the internal components to a great extent through its sealing of the pipeline, so that the detector in the pipeline has good sealing and waterproof properties, and the shape design of the traction joint will reduce part of the running resistance of the detector in the pipeline.

[0027] The sealing plate 2 structure of the in-pipe detector described in the present invention has the following advantages and beneficial effects: it provides a pulling point for the in-pipe detector to facilitate the removal of the in-pipe detector from the tested pipeline at the end of the test. During the test process, the force exerted on the pipeline medium during the operation of the in-pipe detector is reduced, and the pipeline medium is effectively prevented from entering the interior of the in-pipe detector structure and contacting the internal circuit components, and has good sealing and blocking properties. During the test process, the in-pipe detector is effectively protected to prevent the in-pipe detector from short-circuiting due to water ingress and being unable to work normally. The overall structure has strong stability, is relatively simple in structure, is economical and affordable, and achieves a blocking effect on the in-pipe detector.

[0028] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the solutions disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only; the true scope and spirit of the invention are indicated by the claims.
