Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline sealing detection, and in particular relates to a robot for pipeline sealing detection. Background Art

[0002] A pipeline robot is an integrated mechanical, electrical and instrumentation system that can automatically walk along the inside or outside of a small pipeline, carry one or more sensors and operating machinery, and perform a series of pipeline operations under the remote control of the staff or the automatic control of the computer. Among the pipeline robots that have been realized, they can be divided into wheeled, crawler, vibrating and creeping types according to the travel mode. In-pipeline detection refers to the use of pipeline medium to drive the detector to run in the pipeline, real-time detection and recording of pipeline deformation, corrosion and other damage, and accurate positioning. Most oil and gas pipelines are laid underground. Through in-pipeline detection, various defects and damages can be discovered in advance, and the degree of danger of each pipe section can be understood. Accidents can be prevented and effectively reduced, and pipeline maintenance funds can be saved. It is an important measure to ensure pipeline safety.

The utility model detects the pipeline by using the vehicle body to carry the air coupling sensor detection component, which reduces its own volume, makes it more convenient to move in the pipeline, and improves the convenience of internal pipeline detection. At the same time, compared with traditional detection devices, it abandons the large volume and is more flexible at the bend inside the pipeline; the use of air coupling sensing technology reduces the contact between the ultrasonic sensor and the test piece, which can greatly extend the service life of the sensor.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 4,

[0032] First embodiment:

[0033] The utility model provides a technical solution: a pipeline sealing detection robot, comprising a body 1, a driving component 2 is installed outside the body 1, an adjusting component 3 is connected to the body 1, and the adjusting component 3 can be adjusted in direction by setting the adjusting component 3; a video detection component 4 is connected to the adjusting component 3, and the video detection component 4 is set, and the video detection component 4 includes a camera, an air coupling receiving sensor, a data signal line, etc., and is used to observe the pipeline sealing; a steering device 5 is connected to one side of the body 1, a long groove 6 is opened on the lower surface of the body 1, and a collecting device 7 is arranged in the long groove 6, and the steering device 5 includes a fixing rod 51, a fixing rod 52, and a fixing rod 53. The front and back sides of the fixed rod 51 are connected to a connecting rod 52, and one side of the connecting rod 52 is connected to an inclined plate 53, and a sliding rod 54 is arranged inside the inclined plate 53. By setting the inclined plate 53 and the sliding rod 54, the inclined plate 53 cooperates with the sliding rod 54, so that the inclined plate 53 limits the sliding rod 54 to prevent the sliding rod 54 from shaking when sliding; one end of the sliding rod 54 is connected to a circular plate 55, and a return spring 56 is arranged on the outer sleeve of the sliding rod 54. By setting the return spring 56, the return spring 56 applies elastic force to the circular plate 55, so that the roller 58 is always in contact with the inner wall of the pipe; the other end of the sliding rod 54 is connected to a shell 57, and a roller 58 is rotatably connected inside the shell 57.

[0034] Specifically, Figure 3 As shown, a through hole is opened in the inclined plate 53, and the slide rod 54 is slidably connected in the through hole, and the diameter of the through hole is slightly larger than the diameter of the end face of the slide rod 54, one end of the return spring 56 is connected in the circular plate 55, and the other end of the return spring 56 is connected in the inclined plate 53, and an anti-skid rubber pad is provided on the outside of the roller 58. By setting the anti-skid rubber pad, the anti-skid rubber pad can fit inside the pipe to avoid sliding.

[0035] During operation, when passing a corner, the roller 58 on one side contacts the corner of the pipeline first, and then the roller 58 applies a thrust to the connecting rod 52 while turning and rolling. At this time, the return spring 56 applies an elastic force to the circular plate 55, and the elastic force drives the circular plate 55 to move. The circular plate 55 drives the slide bar 54 to slide in the inclined plate 53, and then an elastic force is applied to the shell 57 and the roller 58, so that the roller 58 always keeps in contact with the turning point of the pipeline. At this time, the roller 58 drives the vehicle body 1 to rotate, thereby avoiding the difficulty of the vehicle body 1 in making smooth turns according to the curvature of the curve, which may cause the vehicle body 1 to get stuck at the corner of the pipeline.

[0036] Second embodiment:

[0037] Specifically, Figure 4As shown, the collecting device 7 includes a motor 71, a guide plate 74 and a collecting box 75. The motor 71 is connected through the long slot 6. The output end of the motor 71 is connected to a rotating shaft 72. Three scrapers 73 are arranged outside the rotating shaft 72. The guide plate 74 is fixed in the long slot 6 by bolts. The collecting box 75 is installed in the long slot 6 by bolts. A bearing is sleeved on one end of the rotating shaft 72. By setting the rotating shaft 72 and the bearing, the rotating shaft 72 cooperates with the bearing, so that the bearing limits the rotating shaft 72 to avoid shaking of the rotating shaft 72 when it rotates; and the collecting box 75 is connected in the long slot 6 by a bearing. The collecting box 75 is overlapped on one side of the guide plate 74, and one side of the guide plate 74 is slightly higher than the collecting box 75, and the scraper 73 is arranged as an elastic rubber plate.

[0038] When the vehicle body 1 moves in the pipeline, the motor 71 is started, and the motor 71 drives the rotating shaft 72 and the scraper 73 to rotate. The scraper 73 cleans and scrapes the sludge or garbage in the pipeline. Then, the scraper 73 applies thrust to the garbage while rotating, and the thrust drives the garbage to pass through the guide plate 74 and fall into the collection box 75, thereby realizing the cleaning of the pipeline while detecting the sealing.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
