10. The nuclear power plant material grabbing and transferring shielding device according to claim 1, wherein: the working method of the nuclear power plant material grabbing, transferring and shielding device specifically comprises the following steps:
step 1: the method comprises the steps of connecting a crane with a hanging rod (32) on a transferring shielding container (20), integrally hanging the transferring shielding container (20), then placing the transferring shielding container (20) above a filter element (14), pulling a rotary pulling piece (22) through a hanging rope (12) on the left side, enabling one end of a grabbing pin shaft (23) to slide to one side by the bottom end of the rotary pulling piece (22), inserting the top end of the filter element (14) into the grabbing frame (21), controlling the hanging rope (12) on the left side to move downwards, and enabling one end of the grabbing pin shaft (23) to be inserted into the filter element (14) under the pushing of the rotary pulling piece (22);
step 2: the method comprises the steps of integrally hanging a transferring shielding container (20) above a storing shielding container (40), opening a storing shielding top cover (50), placing a filter element (14) at the bottom into a storing cavity in the storing shielding container (40) by controlling a grabbing component (13) in the transferring shielding container (20), continuing hanging the filter element (14) through the transferring shielding container (20) to be sent into the storing shielding container (40) until the filter element (14) is stored in two storing cavities in the storing shielding container (40), and finally hanging one filter element (14) by using the transferring shielding container (20) to be placed on a vehicle body (10) for storage;
step 3: after the transfer shielding container (20) is placed on the vehicle body (10) for positioning, the bottom of the transfer shielding container (20) is sealed by utilizing the shielding seat (17), and meanwhile, four groups of pressing plate screws (34) are utilized to drive pressing plates (33) to lock and position the periphery of the bottom of the transfer shielding container (20);
step 4: the driving wheel (42) is driven to rotate by the driving gear motor (41) on the right side of the vehicle body (10), so that the vehicle body (10) moves in a walking way, and the steering gear motor (45) on the left side of the vehicle body (10) is matched with the steering gear motor (45) to drive the steering wheel (46) to steer by utilizing the steering longitudinal axis (47) and the steering transverse axis (48), so that the vehicle body (10) flexibly steers in the walking process;
step 5: when the filter element (14) is transported by the vehicle body (10), the residual liquid in the storage shielding container (40) and the vehicle body (10) is discharged by opening the pagoda ball valve (100) at the bottom end of the liquid discharge pipe (90), and finally the pagoda ball valve (100) is closed.
