Abstract
The utility model provides a device of spherical fuel element fuel area position of monitoring, includes the support frame, and the measuring stick is installed on the support frame, and installs the hand wheel on the top of measuring stick, twists the hand wheel and drives the measuring stick and reciprocate.
Description
Technical Field
The invention relates to the field of manufacturing of a pressurized water reactor nuclear fuel element, in particular to a device for monitoring the position of a fuel area of a spherical fuel element.
Background
The domestic spherical fuel element forming process is characterized by that the dressing granules containing UO2 and graphite powder are mixed and initially pressed to form fuel zone, then the fuel zone is uniformly covered with a layer of graphite powder, and finally pressed to form the final-pressed element spherical blank, and the graphite layer uniformly covered on its external surface is fuel-free zone.
In the existing method for monitoring the position of the fuel area, the fuel area is placed in a silica gel mold added with graphite powder by using a mechanical arm, the central position of the fuel area is determined by an industrial camera punctuation, and then the central position is determined, so that the position of the fuel area is monitored. However, after the production line is automatically modified, the height position of the fuel area can only be observed by a camera during continuous production; when the position of the fuel area is adjusted, no reference object is arranged; the position of the fuel area can only be determined by spot inspection of an X-ray machine, and real-time monitoring can not be realized.
Disclosure of Invention
The invention aims to: the existing method for monitoring the position of the fuel-free zone of the spherical fuel element has the defects that the position of the fuel zone can be determined only by visual observation during continuous production; when the position of the fuel area is adjusted, no reference object exists; the fuel area position can only pass through X-ray machine spot check, can not realize real-time supervision. Therefore, a new method for monitoring the position of the fuel area is provided, the position of the fuel-free area can be measured by using a tool, and the position can be monitored in real time by using a specific reference object.
The technical scheme of the invention is as follows: the utility model provides a device of spherical fuel element fuel area position of monitoring, includes the support frame, and the measuring stick is installed on the support frame, and installs the hand wheel on the top of measuring stick, twists the hand wheel and drives the measuring stick and reciprocate.
The measuring rod is installed on the supporting frame through a fixing nut.
And a scale plate is also arranged on the side surface of the measuring rod.
The invention has the following remarkable effects: the position of the fuel-free area can be measured by using a tool, and the position can be monitored in real time by using a specific reference object.
