Preferably, buffering pipeline section connection adjunction in a manner of ring flange buffers jumping fiber.
Compared with immediate prior art, the invention has the advantages that：
1st, device provided by the invention can be in 300 meters of operated by water pressure, while can realize same with the detection of ultrasonic wall thickness
Step carry out fast video detection, reach as high as 200 meters/per hour, effect speeds are significantly larger than device of the prior art.
2nd, device provided by the invention is using video camera and shooting aircraft window so that video camera can work under water, overcome
The cumbersome technical problem that need to be brought in the prior art under pipe well water-less environment using PTZ devices, is realized most
Can be to the technique effect of quick detection under more than 300 meters of hydraulic pressure；
Further, because it is without using Pan/Tilt/Zoom camera, so as to solve in the prior art Pan/Tilt/Zoom camera because of it
There is single camera lens, captured in real-time needs to rotate a circle that whole pipeline section could be covered, and ensures that declining certain depth rotates a circle then
Need to reduce the problem of detection speed causes detection caused by detecting exhaustive slow, so as to improve detection speed, carry significantly
High operating efficiency；
And due to without using special Pan/Tilt/Zoom camera, reducing installation cost.
