Description
Technical Field
The invention belongs to the technical field of nondestructive testing, and particularly relates to a following type couplant collecting device for ultrasonic inspection of the inner wall of a vertical container.
Background
Containers exist in many devices in a nuclear power plant, and the containers are often in a high-temperature and high-pressure state when the nuclear power plant is operated, so that nondestructive detection is required when the nuclear power plant is shut down for maintenance. For a vertical container placed vertically, a common detection mode is that the container is placed into detection equipment from an orifice at the top to enter the container for detection; for a container with the inside in a dry state during maintenance, the probe needs to continuously spray the couplant to collect ultrasonic signals when performing inner wall ultrasonic detection, a large amount of couplant can be sprayed in the whole detection process, if the couplant is not effectively collected, the couplant can flow to the bottom of the container along the inner wall of the container, then flows to other equipment from a pipeline at the bottom of the container, and the maintenance of other equipment is possibly influenced, so that the couplant sprayed by the ultrasonic probe during detection needs to be timely and effectively collected.
When the ultrasonic detection is carried out on the inner wall of the container, the equipment can carry out lifting and rotating movements, if the equipment carries a sealing baffle plate which enters the inner wall of the container through the opening of the container and is completely and tightly attached to the inner part of the whole container to play a role in collecting the couplant, the equipment with larger area of the sealing baffle plate is carried unchanged, and the sealing structure is difficult to form in the whole circumferential direction; if the pipe orifice at the bottom of the container is plugged in advance, on one hand, as more coupling agent is sprayed and flows down, the sealing effect is uncertain, and on the other hand, the plugging plate is mounted and retrieved at risk; it is therefore desirable to design a couplant collection device that can follow the motion of a test probe to address the above issues.
