Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a pipeline detection device for ship design and transformation. Background Technique

[0002] Ship pipelines are pipes used to connect various mechanical equipment on ships to convey working media such as water, oil, and gas. There are two major categories of ship pipelines: power pipelines and ship system pipelines. During long-term use, pipelines usually have problems such as cracks and blockages. Therefore, it is necessary to manually detect the pipelines regularly for subsequent use. The Chinese patent discloses a pipeline detection device for ship design and transformation (authorization publication number CN219912227U). This patented technology discloses a pipeline detection device for ship design and transformation, including a detector. On the outer side of the detector, two telescopic rods are fixedly installed and distributed symmetrically up and down. The output ends of the two telescopic rods are fixedly installed with mounting plates. On the inner sides of the two mounting plates, two rollers are rotatably connected and distributed symmetrically left and right. This pipeline detection device for ship design and transformation has the advantages of strong adaptability and solves the problem that in the prior art, during the crawling of the crawler inside the pipeline, the adaptability of the pipeline is not strong, the moving wheels cannot be adapted to pipelines of different sizes, and it is easy to be trapped in the pipeline and unable to move, reducing the practicality. This patented technology solves the problem of the common pipeline crawler for pipeline detection. When in use, the crawler is driven to move inside the pipeline by driving the wheels to rotate by a motor. However, the terrain inside the pipeline is relatively complex, with high and low parts and turning situations. In the prior art, during the crawling of the crawler inside the pipeline, the adaptability of the pipeline is not strong, the moving wheels cannot be adapted to pipelines of different sizes, and it is easy to be trapped in the pipeline and unable to move, reducing the practicality.

[0003] However, in the prior art, the rollers only abut against both sides of the pipeline. When the pipeline is relatively large, it is easy to cause the rollers to loosen when moving with the pipeline. It is necessary to solve the problem of the stable movement of the driving wheels in equal-distance contact with the ship pipeline in the prior art.

[0004] Therefore, the technical personnel in this field provide a pipeline detection device for ship design and transformation to solve the problems raised in the above background technique. Content of the Utility Model

A number of screw cylinders are movably arranged at equal intervals in a ring shape on the inner wall of the ring shaft frame, and a screw rod is screw-driven inside the screw cylinder. One end of the screw rod rotates through the ring shaft frame, and a first bevel gear is fixed, and the first bevel gear meshes with a bevel gear ring, and the bevel gear ring is rotatably installed outside the installation cylinder; the bevel gear ring meshes with a second bevel gear, and the second bevel gear is connected to a first servo motor.

[0014] The technical effects and advantages of the present utility model:

[0015] 1. By adjusting the distance between the driving wheel and the detection vehicle frame, the system can be applied to ship pipelines of different specifications.

[0033] According to the above embodiments, the working principle of the present invention is as follows:

[0034] The pipeline power mechanism 2 can adjust the distance between the driving wheel 208 and the detection vehicle frame 1 to make it suitable for ship pipelines of different specifications.

[0035] By starting the first servo motor 211, the first servo motor 211 drives the second helical gear 210 to rotate. The second helical gear 210 rotates and meshes with the helical ring 203 to rotate, so that the helical ring 203 rotates along the installation cylinder 201, and the helical ring 203 drives a plurality of first helical gears 204 to rotate in a ring shape.

When cracks appear on the inner wall of the pipeline in the picture, the annular surface imaging mechanism 3 can be used for detailed picture detection.

[0038] When the camera 309 adjusts to the crack position in the pipeline, by starting the second servo motor 306, the second servo motor 306 drives the spur gear 305 to rotate. The spur gear 305 rotates and meshes with the internal gear ring 304 to rotate. The internal gear ring 304 drives the adjustment ring 303 to rotate along the ring shaft body 302, so that the camera 309 rotates to the crack of the pipeline, which is convenient for detecting the picture at the crack of the inner wall of the pipeline.
