Coupling agent collecting device for pressure vessel inspection and inspection system

The utility model discloses a coupling agent collecting device for pressure vessel inspection and an inspection system, which belong to the technical field of nondestructive testing of pressure vessels in nuclear power stations and comprise a collecting mechanism, the collecting mechanism is arranged between a pressure vessel and a condenser pipe and is positioned below a welding seam of the pressure vessel, and the collecting mechanism comprises waterproof cloth made of waterproof materials. The waterproof cloth is flatly laid between the pressure container and the condensation pipe and used for collecting the coupling agent splashed at the probe and conveying the collected coupling agent to the coupling agent collecting tank. Splashing coupling agents are collected through the waterproof cloth, the coupling agents are conveyed into the coupling agent collecting groove of the pressure container to be discharged in a concentrated mode, the coupling agents can be prevented from being scattered and splashed to
