Description
Technical field
The present invention relates to reactor engineering field, the device of specially a kind of continuously adjustable ionisation chamber pipeline location and side
Method.The present invention can effectively adjust the position of ionisation chamber pipeline, and simple in construction, easy to operate, easy to maintain, have higher
Application value and preferable application prospect.
Background technology
Ionisation chamber pipeline is mainly used in installing the neutron detector of reactor（Entitled ionisation chamber）.In reactor, need
Multiple ionisation chambers are installed to measure, and Measurement and Control System requires that these ionisation chamber measurement signals are basically identical.And
Ionisation chamber is big apart from the nearly then measurement signal of reactor core, otherwise measurement signal is small, and this just needs every ionisation chamber pipeline individually to adjust
Its whole position, so as to adjust the output current signal of ionisation chamber, to meet the requirement of measurement.
Existing ionisation chamber pipeline location adjusting means is as shown in figure 1, the device includes being used to support ionisation chamber pipeline
Lower supporting plate, several positioning holes is provided with the lower supporting plate, by the way that ionisation chamber pipeline to be arranged on to different positioning holes
On, to realize the regulation of ionisation chamber pipeline location.
However, existing ionisation chamber pipeline location adjusting means has the disadvantage that：
1）Positioned due to using in ionisation chamber pipeline positioning hole different on lower supporting plate so that ionisation chamber pipeline location
Adjustment is discontinuous；
2）Because the length of ionisation chamber pipeline is very long（Typically for up to ten meters or so）, positioning hole very little, in ionisation chamber pipeline
When upper end operates, the position of positioning hole can not be seen at all, this make it that the position adjustment of ionisation chamber pipeline is extremely difficult, or even goes out
Situation about can not now adjust.
Chinese patent CN201410318271.1 discloses a kind of simulated fuel assembly subchannel heating rod spacing regulation dress
Put, the device includes：Position regulating system；The position regulating system is located at the device upper end, the position regulating system bag
