Abstract: A deep-sea manned submersible and a design method for a pressure resistant hull curved structure thereof, the deep-sea manned submersible comprising a main hull body, a propeller assembly, annular sliding channels, a brake disc, and a brake. Two annular sliding channels are provided, and are fixed symmetrically on two opposite side surfaces of the main hull body. The main hull body is inserted vertically through the upper surface of the propeller assembly, and by means of the two annular sliding channels is slidingly connected to the propeller assembly, such that the outer contour of the whole body formed by the impeller assembly and the main hull body takes a nautilus shell shape. The brake disc is of an annular shape, and fixed on an outer ring of the main hull body, and the brake is mounted on the propeller assembly and corresponds matchingly with the brake disc.

Abstract: A moving-rotating linear covering tool, comprising a port, a primary oil cylinder, a piston rod, a rear end cover, a base sleeved on the right end of the primary oil cylinder, and a handle fixedly connected onto the outer cylinder of the base. The port is fixedly connected to the left end of the primary oil cylinder, the center thereof being provided with a circular hole that clearance-fits the piston rod arranged in the primary oil cylinder. A circular flange of the rear end cover is fixedly connected onto the right end face of the primary oil cylinder. The base is connected to a guide supporting sheath sleeved, in a clearance-fitted way, on the outer cylinder of the primary oil cylinder. A bearing seat is provided on the right end wall of the base Two screw holes are symmetrically provided at the right end face of the rear end cover.
