Detailed Description

As figure 1, the utility model discloses a self-sinking formula sea equipment body stripping off device, include the airtight cavity of being connected formation on casing 7 by end cover 4, end cover 4 passes through threaded connection at the opening part of casing 7. The end cover 4 and the shell 7 are made of nylon materials, and have good heat insulation performance and corrosion resistance. A movable pin 5 extending out of the end cover 4 is arranged in the shell 7. As shown in fig. 2 and 3, the movable pin 5 is T-shaped, and includes a movable pin partition plate 51 with a large outer diameter and a movable pin cylindrical rod 52 with a small outer diameter, the movable pin partition plate 51 is equivalent to a piston, the movable pin cylindrical rod 52 is equivalent to a piston rod, and the movable pin partition plate 51 is in a cross-petal shape, or holes are distributed on it, so that two sides thereof are communicated.
