[0002] The burying plow is a device specially used for laying and burying cables (especially laying submarine cables). The burying plow comprises a plow body. When the burying plow is towed on the seabed, the plow body of the burying plow can excavate a trench in the seabed soil through a high-pressure water gun, and a submarine cable (i.e., a submarine cable, the same below) can be placed in the excavated trench through the plow body. During the submarine cable laying operation, when foreign matters (such as sand or seabed plants) enter the plow body, the submarine cable can be stuck in the plow body. At this time, the foreign matters need to be cleaned to continue the operation. Since the existing plow body is in the form of an integrated pipe, the cleaner cannot observe the position of the foreign matters in the plow body, the internal space of the plow body is narrow, and tools cannot enter to clean the foreign matters, so that it is inconvenient to clean the foreign matters. Therefore, the existing plow body has the problem of inconvenience in cleaning foreign matters. CONTENT OF THE UTILITY MODEL
