The control unit 30 is configured to determine the deformation amount of the dome of the containment vessel 40 according to the positional information of each target unit 20 measured by each detector 10. In the device, the detector can acquire the accurate image of the target unit, so that the accurate position information of the target unit can be obtained by analyzing the image, and the accuracy of measuring the deformation of the containment dome can be improved. Compared with an instrument which cannot perform measurement in a dark or low-light environment, the device overcomes the limitations through the combination of the detector and the target unit, and can improve the measurement efficiency while saving manpower. In addition, through measuring device, can obtain measurement data many times, realize real-time supervision to carry out trend analysis, early handle potential dangerous condition according to these data.
In one embodiment, as shown in fig. 2, the target unit 20 includes a light emitting sub-unit 201, a bracket 202, and a connection plate 203 on the basis of the measuring device of the containment dome deformation of the nuclear power plant described in the embodiment of fig. 1; two ends of the bracket 202 are respectively connected with the light-emitting subunit 201 and the connecting plate 203; the connection plate 203 is fixed to the surface of the inner shell of the containment vessel facing the outer shell.
Wherein the light emitting subunit 201 is configured to emit light to the detector 10, so that the detector 10 can obtain the position information of the target unit 20. The light emitting subunit 201 may be an infrared lamp, a reflective ball, or a light emitting subunit such as a laser. The support 202 is used for adjusting the height and angle of the light emitting sub-unit 201, and the support 202 may be made of a wood material or other materials, and the specific materials used are determined according to actual requirements, which is not limited in this embodiment. The connection plate 203 is adapted to be fixed to a surface of the inner shell 401 of the safety housing 40 facing the outer shell 402 for supporting the light emitting sub-unit 201 and the holder 202. The connection board 203 may be made of a wood material or other materials, and the specific material used is determined according to actual requirements, which is not limited in this embodiment.
In the embodiment of the present application, when a plurality of target units 20 are disposed on the surface of the inner shell 401 of the containment vessel 40 facing the outer shell 402, the light emitting subunit 201, the bracket 202 and the connection board 203 in the target units 20 may be assembled first, and whether the functions of the respective parts are normal is checked, then the position of the target units 20 is determined, and then the connection board 203 is adhered to the outer surface of the inner shell 401 of the containment vessel 40. In the above embodiment, the light emitting target 20 can be adjusted in height, so as to avoid the situation that measurement cannot be performed due to the measurement position.
In one embodiment, based on the measuring device for the deformation of the containment dome of the nuclear power plant described in the embodiment of fig. 2, the plurality of target units 20 includes a plurality of first target units 204 and a plurality of second target units 205, and the plurality of first target units 204 are disposed at a first preset distance along a horizontal axis on the surface of the inner shell 401 of the containment 40 facing the outer shell 402; the plurality of second target units 205 are disposed at a second preset distance along the vertical axis on the surface of the inner case 401 of the safety case 40 facing the outer case 402.
Wherein the first targeting unit 204 is a targeting unit mounted in a first orientation of the containment dome in top view (see targeting unit 20 in the east-west orientation of fig. 2). The second targeting unit 205 is a targeting unit mounted in a second orientation of the containment dome in top view (see targeting unit 20 in the north-south orientation of fig. 2). The first predetermined distance is the distance between each adjacent first targeting unit 204. The second preset distance is the distance between each adjacent second targeting unit 205. The first preset distance and the second preset distance may be the same or different.
In this embodiment of the present application, when the target unit 20 is installed, between the plurality of first target units 204, every two adjacent first target units 204 may be spaced apart from each other by a first preset distance, on the surface of the inner shell of the containment vessel facing the outer shell, along the horizontal axis.

As shown in fig. 8, the difference in height between the nth target unit of the group a and the reference target unit at time t1 can be determined to be H (N, reference) t1 by referring to the positional information of the target and the positional information of each of the remaining target units.

Specifically, the vertical deformation amount of the nth measurement point of the group a at the time t1 is:
ΔH (N, reference) t 1 =h (N, reference) t 1 -H (N, reference) t 0
The vertical deformation of the center position of the dome is as follows:
