When a worker clamps the blocking block 8 into the clamping grooves 81 on the first leakage blocking sheet 2 and the second leakage blocking sheet 3, the blocking block 8 and the sealing layer 7 are made of soft silica gel materials and are made of the same materials, so that the blocking block 8 is in interference fit with the clamping grooves 81 after being clamped into the clamping grooves 81, the contact part of the blocking block 8 and the clamping grooves 81 is compressed, the contact is tight, and liquid leaked from an oil transportation pressure pipeline is prevented from leaking from the clamping position of the blocking block 8 and the clamping grooves 81, and the use effect of the oil transportation pressure pipeline is influenced;
after the oil conveying pressure pipeline is sleeved with the oil conveying pressure pipeline leakage part, liquid leaked from the oil conveying pressure pipeline is in contact with the blocking block 8 with the cup-shaped opening and enters the blocking block 8, the blocking block 8 is expanded outwards, and therefore the outer wall of the blocking block 8 is tightly attached to the inner walls of the first leakage blocking sheet 2 and the second leakage blocking sheet 3 and is extruded under the action of thrust of the leaked liquid of the oil conveying pressure pipeline, the leakage of the liquid leaked from the oil conveying pressure pipeline from the clamping position of the blocking block 8 and the clamping groove 81 is prevented again, and the using effect of the oil conveying pressure pipeline leakage prevention device is improved;
the support ring 82 made of metal (e.g., steel) supports the blocking block 8 when the blocking block 8 is clamped into the clamping groove 81 by a worker, so that the blocking block 8 with an open cup shape is prevented from deforming after contacting the clamping groove 81, and the blocking block 8 does not enter the clamping groove 81 with interference fit, thereby ensuring the practical use effect of the invention.
