Full-automatic helium leakage detection device for fuel rods

Abstract

The invention relates to a full-automatic helium leakage detection device for fuel rods. The device comprises a feeding device, a conveying trolley, a leak detection container and a discharging device. The conveying trolley is arranged on the opening side of the leak detection container and used for conveying fuel rods to be detected to the leak detection container; the feeding device is arranged on one side of the conveying trolley and used for receiving the fuel rods from the previous working procedure and conveying the fuel rods to the conveying trolley; the discharging device is arranged on the other side of the conveying trolley and used for disassembling the detected fuel rods from the conveying trolley and conveying the detected fuel rods to the next working procedure. According to the leak detection device, the sealing performance of the fuel rods can be detected in batches in a nuclear fuel component production line, the helium leak detection working procedure is connected with previous and later working procedures on a production line, automatic operation of the whole process of feeding, leak detection and discharging of the helium leak detection device is achieved, the problems of artificial offline detection, low production efficiency and the like existing in the existing helium leak detection process are effectively solved, the production efficiency and economic benefits are improved, and the device is simple in structure, safe and reliable.
