Embodiment 1
[0047] Such as figure 1 and figure 2 As shown, the spent fuel storage grid underwater installation position measurement device and grid installation method, the measurement device includes a device base 1 and a measurement component installed on the device base 1, the measurement component includes an expandable and retractable The link mechanism 2, the contact point 3 installed on the link mechanism 2, is connected with the link mechanism 2, and is used to drive the lifting rod 4 deformed by the connecting rod mechanism 2, and the displacement sensor 5 used to detect the displacement of the lifting rod 4;
[0048] A friction pair is also provided between the measurement assembly and the device seat 1 , and the friction pair is used to realize that the deformed state of the link mechanism 2 is maintained through the friction force between the measurement assembly and the device seat 1 .
[0049] In the prior art, due to the deepness of the spent fuel pool and the radioactive...
Embodiment 2
[0065] The present embodiment is further limited on the basis of embodiment 1, as figure 1 and figure 2 As shown, as a specific implementation of the link mechanism 2, it is set as follows: the link mechanism 2 is a multi-link mechanism 2 including a variable vertex angle relative to the device frame, and the vertex angle is formed on two sides. The connecting position of the connecting rod, the changeable position is synchronized with the change of the shape of the connecting rod mechanism 2, and the contact is set at the top angle position. As a person skilled in the art, the joint position of the two connecting rods is the hinged position. In the case of extrusion, the corresponding hinged position will rotate relative to each other, and the magnitude of the relative rotation will be affected by the size of the corresponding gap above, and finally pass through the displacement sensor. 5. Obtain the specific location of the storage grid to be installed in the spent fuel po...
Embodiment 3
[0075] This embodiment provides a more specific installation method on the basis of Embodiment 1: measurement process;
[0076] a. Check and test the loose parts of the measuring device;
[0077] b. Press down the lifting rod 4 to open the upper link mechanism 2 of the measuring device;
[0078] c. Connect the clamping piece 6 of the measuring device to the spent fuel storage grid, adjust the relative position to the grid, and then lock it;
[0079] d. Connect the measuring device with the control system;
[0080] e. Hoist the spent fuel storage grid together with the measuring device into the approximate installation position in the spent pool;
[0081] f. Confirm that the spent fuel storage grid is not in contact with the bottom of the pool, and the bottom of the grid is about 10-15mm higher than the bottom of the pool;
[0082] g. Use the push device to push the spent fuel storage grid;
[0083] h. After the contact 3 of the measuring device contacts the outer surface o...
