Description
Technical field
The utility model relates to a kind of device of compressed natural gas storage well detection field, specifically relates to a kind of compressed natural gas storage well video detecting device.
Background technology
The underground pipe well detection systems such as compressed natural gas (CompressedNaturalGas is called for short CNG) gas storage well, need to carry out macroscopical video detection to pipe well inwall in detection code.Technical method of the prior art is, use camera video detects, common method is by wired use and controls special PTZ (Pan/Tilt/Zoom, represent video The Cloud Terrace all-around mobile and camera lens zoom, Zoom control) camera system, realize by the display of ground main control system, the underground state observing gas storage well.
But, although the method for prior art can reach the video observing observation of eyes, but because Pan/Tilt/Zoom camera is owing to only having single camera lens, captured in real-time needs to rotate a circle to cover whole pipeline section, guarantee that decline certain depth rotates a circle, need to reduce detection speed and make to detect without omitting, thus cause its detection speed too low, and the degree of depth of general CNG gas storage well is maximum reaches 300 meters, the detection of a bite well just needs the time of one day.
Simultaneously, said method is because employing PTZ device, be difficult to realize high pressure watertight (high pressure, waterproof, sealing) design, can only detect in anhydrous situation in pipe well, and after practical logging scene has to pass through water filling well-flushing, detect when having filled water in pipe well, as emptying in needed, operate pretty troublesome, very time-consuming.
For solving the problem, the utility model proposes a kind of compressed natural gas storage well video detecting device, can work under phreatic water pressure ring border, and to realize and ultrasonic wall thickness detects the fast video synchronously carried out and detects.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of compressed natural gas storage well video detecting device.
Realizing the solution that above-mentioned purpose adopts is:
A kind of compressed natural gas storage well video detecting device, described device comprises the halter, video detection pipeline section and the Ultrasonic Detection instrument that connect successively;

Preferably, described buffering pipeline section connects with ring flange mode adjunction buffering jumping fiber.
Compared with immediate prior art, the utility model has following beneficial effect:
1, the device that provides of the utility model can at 300 meters of operated by water pressure, can realize detecting with ultrasonic wall thickness the fast video synchronously carried out simultaneously and detect, reach as high as 200 meters/per hour, effect speeds is far away higher than device of the prior art.
2, the device that the utility model provides adopts video camera and shooting aircraft window, video camera can be worked under water, overcome and need adopt PTZ device under pipe well water-less environment in prior art and the technical matters of the complex operation brought, realize at the technique effect that can detect fast to more than 300 meters of hydraulic pressure at most;
Further, because it is without the need to adopting Pan/Tilt/Zoom camera, thus solve Pan/Tilt/Zoom camera in prior art and only have single camera lens because of it, captured in real-time needs to rotate a circle to cover whole pipeline section, guarantee that decline certain depth rotates a circle, need to reduce detection speed and make to detect the detection problem slowly that nothing left leakage conductance causes, thus improve detection speed, substantially increase work efficiency;
And, due to without the need to adopting special Pan/Tilt/Zoom camera, reduce installation cost.
