Problems solved by technology

[0002] During the pigging operation, most of the pipeline robots use the traversal dredging method when cleaning the pipeline. The pertinence and target of the dredging are not strong, and the mud cleaned on the pipe wall cannot be removed in time when the water flow is insufficient. away, it is easy to cause secondary deposition and blockage

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with specific embodiments.

[0029] Such as Figure 1 to Figure 7 In the pipeline robot automatic inspection and dredging device shown, first, the pipeline robot equipped with sensors and waterproof cameras 2-3 is manually inserted into the pipeline, and then the sensors and waterproof cameras 2-3 detect the size and distance of the silt in the pipeline , to drive the robot to move towards the silt, and then the stepper motor 3-2 drives the scraper knife group 1-1 to rotate to scrape off the silt, and then controls the blade to press the silt to the middle and lower parts of the pipeline in a pendulum cutting manner, at the same time Ensure that the height of the sludge does not exceed the center of the pipe.

[0030] Since the projected area of ​​the desilting knife group 1-3 in the direction of the pipeline section is much larger than that of the desilting knife group 1-1, first turn the d...

Abstract

The invention discloses an automatic pipeline robot patrolling and dredging device. The automatic pipeline robot patrolling and dredging device comprises a dredging unit, a video unit and a patrollingdrive unit. The dredging unit is arranged at the front end of the patrolling drive unit. The video unit is fixed in the dredging unit. The video unit and the patrolling drive unit are coaxially arranged. A sludge scraping cutter set and a sludge retreating cutter set are connected to a hollow disc frame. The hollow disc frame is connected to the patrolling drive unit and can freely rotate aroundthe axis of the patrolling drive unit. A transposition driver is fixed to the patrolling drive unit, a synchronous belt wheel is fixed to the hollow disc frame, and a synchronous belt is arranged between the transposition driver and the synchronous belt wheel. Through vision detection of a camera and the action that a stepping motor drives the sludge scraping cutter set and the sludge retreating cutter set to coordinate and cooperate, one stepping motor can control the positions of the sludge scraping cutter set and the sludge retreating cutter set, and the pipeline cleaning efficiency and thepipeline cleaning accuracy are improved; and patrolling, sludge scraping and sludge retreating functions are integrated, and pertinence and adaptability to the pipeline environment are improved.

Description

technical field [0001] The invention relates to the technical field of pipeline desilting robots, in particular to a pipeline robot automatic inspection and desilting device and a desilting method based on the integrated linkage and coordination of scraping and desilting, which can realize the functions of detection and desilting in horizontal pipelines. Background technique [0002] During the pigging operation, most of the pipeline robots use the traversal dredging method when cleaning the pipeline. The pertinence and target of the dredging are not strong, and the mud cleaned on the pipe wall cannot be removed in time when the water flow is insufficient. It is easy to cause secondary deposition and blockage. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a pipeline robot automatic inspection and dredging device and protection method, through the visual detection ...
