Special device for reactor control rod bundle inspection equipment and use method thereof

The invention discloses a special device for reactor control rod bundle inspection equipment and a using method of the special device. The special device comprises a supporting frame, a containing piece, a water storage tank and a water level height adjusting assembly. According to the special device for the reactor control rod bundle inspection equipment and the use method thereof, the problem that the maintenance and debugging work of the conventional reactor control rod bundle inspection equipment can be completed only by multiple times of hoisting cooperation depending on field conditions is solved, the hoisting process is reduced, the working time and the personnel radiation dose are reduced, and the maintenance efficiency is improved. Meanwhile, the special device can flexibly adjust the water level height of the accommodating part according to actual requirements by utilizing the water level height adjusting assembly, and achieves the purpose of switching the maintenance and debugging modes by realizin
