Abstract

The invention relates to a hatch cover of a submerged body in polar regions with self-ice-breaking function, which comprises a submersible body, a hatch cover hinged on the inner side of the shell wall of the submerged body and an ice-breaking mechanism arranged under the hatch cover. There is an opening and closing locking device on the inner surface of the hatch cover, which is driven by a pair of opening and closing locking hydraulic cylinders; the ice breaking mechanism is located on the support platform around the opening of the bilge, including hydraulic lifting columns, shells and ice breaking plates , the hydraulic lifting column is installed on the support platform, and the ice-breaking plate is hinged on the shell. The hydraulic lifting column drives the shell and the ice-breaking plate are led out from the top of the access cabin to break the ice layer. There are several ice-breaking drills and hobs on the ice-breaking plate. . The ice-breaking mechanism of the present invention moves up and down to cut the ice layer, adopts the combined structure of the ice-breaking drill and the hob to break the ice from bottom to top, and based on the ice-layer fracture mechanism, it is beneficial to improve the ice-breaking efficiency and thoroughly crush the ice layer above the hatch cover.

Description

technical field [0001] The invention belongs to the technical field of polar region submersible equipment, and in particular relates to a polar region submersible hatch cover with self-icebreaking function. Background technique [0002] The submersible is an important piece of equipment in the development of the Arctic. A large area of ​​the sea in the Arctic is covered by ice. The submersible sails under the ice. On the one hand, it can avoid the ice load induced by sea ice collisions. On the other hand, it can also use The cover of the ice layer is used to avoid the search of satellites and radars. However, in some special cases, the submersible needs to break through the ice and emerge from the water to communicate with the outside world, receive rescue supplies, etc., which puts higher requirements on the icebreaking capability of the submersible. [0003] The main stress-bearing parts during the ice-breaking process of the submersible are the enclosure of the conning t...
