Further, the conveying pipeline is a conveying hose, and the pipeline joint is a hose joint. The beneficial effects are that: the conveying hose can be flexibly bent and deformed and can be suitable for various narrow terrains.

Furthermore, the first stopping structure and the second stopping structure are both circular structures. The beneficial effects are that: the circular stop structure is perfectly matched with the two ends of the tube bundle to be detected, the appearance is attractive, and no edges and corners can not scratch operators.

Further, the through-hole is provided with at least three, and each through-hole evenly sets up at interval along the detection pipe axis direction. The beneficial effects are that: the through holes are uniformly arranged at intervals, so that the production and the manufacture are convenient.

Furthermore, the first stopping structure and the second stopping structure are also provided with annular sealing rings. The beneficial effects are that: the annular sealing ring is arranged to enhance the sealing performance of the first stopping structure and the second stopping structure and the two ends of the tube bundle to be detected, and the detection result is prevented from being influenced by poor sealing of the two ends of the tube bundle to be detected.

The utility model discloses a tube bank seals detection device, during the use with the test tube stretch into wait to detect the tube bank in, the first stop structure at both ends and the sealed cooperation of second stop structure and the both ends stop of waiting to detect the tube bank, go into liquid through the hydraulic pump to the intraductal pump of test, thereby the realization is to waiting to detect the tube bank and suppress and carry out pressure test in the inside passageway of waiting to detect the tube bank that liquid passes through the through-hole entering on the test tube. The tube bundle sealing detection device of the utility model has the advantages of simple structure, low manufacturing cost and convenient use.
