Problems solved by technology

[0002] In the prior art, the hatch cover device that can be opened and closed automatically often adopts hydraulic opening and closing and hydraulic locking. The hydraulic source pipeline system equipped with it is complicated, and oil leakage accidents often occur in the hydraulic system, which is easy to cause the opening and closing and locking mechanism to be damaged. It cannot work normally, the system reliability is poor, and the manned submersible is not equipped with such a complete hydraulic system, so the hydraulic opening and closing is not universal
Its locking mechanism includes wedge-shaped push blocks and supporting rollers. The load-bearing direction of this type of hatch cover is opposite to its own pressing direction. With the increase of external load, the deformation of the locking mechanism will cause the sealing effect of the hatch cover to deteriorate, and even Failure, that is, it can only bear the external load in one direction
In addition, the wedge-shaped push block will cause uneven stress on the hatch cover and poor sealing effect

Abstract

The invention relates to a hatch cover device capable of being automatically opened, closed and locked. The hatch cover device comprises a pressure withstanding shell taper section, the bottom of the pressure withstanding shell taper section is provided with a locking rotary ring through a surrounding wall, a rack base and a support are installed at one end of the pressure withstanding shell taper section, an opening-closing electric push rod is connected to the support, the head of the opening-closing electric push rod is connected with the top of a hatch cover through an opening-closing lever, and the opening-closing lever is hinged to the rack base. A sealing ring is arranged on the inner end face of the hatch cover, and a plurality of wedge-shaped lugs are evenly distributed on the outer end face of the hatch cover in the circumferential direction; protruding lugs are arranged on the inner circumferential face of the locking rotary ring and are divided into the upper layer protruding lugs and the lower layer protruding lugs; the lower layer protruding lugs are matched with the wedge-shaped lugs on the hatch cover; racks are further installed at the other end of the pressure withstanding shell taper section through rack supports, a locking electric push rod is installed through a push rod support, the head of the locking electric push rod is in butt joint with the racks, and gear rings meshed with the racks are installed at one end of the locking rotary ring. The hatch cover device is good in working reliability, has the site operability, and is good in opening-closing locking sealing effect and high in bearing capacity.

Description

technical field [0001] The invention relates to the technical field of ships and manned submersibles, in particular to a single-cover two-way pressure-bearing access hatch cover device capable of automatic opening, closing and locking. Background technique [0002] In the prior art, the hatch cover device that can be opened and closed automatically often adopts hydraulic opening and closing and hydraulic locking. The hydraulic source pipeline system equipped with it is complicated, and oil leakage accidents often occur in the hydraulic system, which is easy to cause the opening and closing and locking mechanism to be damaged. It cannot work normally, the system reliability is poor, and the manned submersible is not equipped with such a complete hydraulic system, so the hydraulic opening and closing is not universal. Its locking mechanism includes wedge-shaped push blocks and supporting rollers. The load-bearing direction of this type of hatch cover is opposite to its own pre...
