Description
Technical field
The present invention relates to nuclear power inspection apparatus field, and in particular to a kind of miniature Liftable type video inspection device.
Background technology
Chinese Nuclear Power career development is rapid, and the safety problem of nuclear equipment is constantly subjected to concern.Sight check is that nuclear power plant exists
Use as a servant one of Main Means of inspection, the extensive use in nuclear power plant's inservice inspection.
Main heat-transfer system pipeline branch pipe suspension and support is the nucleus equipment of nuclear reactor, and the vibrations during running can be produced
Wear-resisting pad wear, suspension and support skew, nut come off and the problems such as pipe wear, it is necessary to often inspect.China's nuclear power station main flow heap
Main heat-transfer system pipeline branch pipe is often arranged and is of five storeys in type, there is 4~5 suspension and supports on every layer of branch pipe.Each suspension and support is sling one
Branch pipe, row and the horizontal tube pitch very little of suspension and support arranged.Due to compact, the interlaced row of suspension and support by inspection suspension and support space structure
Row, narrow space, when the suspension and support examined area of underclad portion uses direct sight check, can only be after heat-insulation layer be removed from logical
Road is observed, and suspension and support and its accessory that so substantially can only be to topmost one layer and near passageway be checked.Work in addition
Narrow space, temperature (35~50 DEG C) high, working environment radiation dose rate are high, also have after steam generator manhole is opened loose
Pollution, and the quantity of suspension and support is more, and the dose of radiation that reviewer is subject to when suspension and support is checked is high, surface pickup and interior dirt
The risk of dye is higher.
For features above, the inspection of suspension and support integrality is carried out using indirect visual means both at home and abroad, in Canada
The bottom suspension and support of CANDU heap-type is used visually is tested using automation equipment (video inspection system) indirectly, using English
The snake-shaped robot of OC companies of state is tested from passageway bottom, long using hand-held after snake-shaped robot breaks down
Bar endoscope is carried out.The country is also without the automation equipment of this kind of inspection, up to the present domestic lower floor suspension and support field test
Also in blank stage.
A kind of Telescopic video inspection device as shown in Figure 3 is occurred in that in existing patent, by setting some supports
Bar and pin connect the scissors front end stretching structure to be formed, and in front end, stretching structure head sets camera module, in actual work
In work, by the contraction or expansion motion of front end stretching structure, the position of camera module is controlled in nuclear reactor suspension and support
Cross directional variations in narrow range, reach video observation purpose, reduce dose of radiation suffered when reviewer detects dirty with loose
Dye.But because camera module position is fixed in the device, the displacement of its in the vertical direction is limited；Meanwhile, its shooting head mould
The observation angle of group only slightly changes with the change of front end stretching structure, and its observation scope is uncontrollable, therefore, it is difficult to reach
Preferable observation effect.
In order to check the integrality of main heat-transfer system pipeline branch pipe suspension and support and its accessory system more fully hereinafter, safeguard
Nuclear power plant equipment safe and reliable operation, the radioactive dose for improving inspection technology ability, reducing reviewer, develop a tackling now
There is the video inspection device tool that vertical lifting is realized in narrow space to be of great significance and necessity.
