Abstract

The invention relates to a polar region submerged body hatch cover with a self-icebreaking function. The polar region submerged body hatch cover comprises a submerged body, a hatch cover rotationally hinged to the inner side of a shell wall of the submerged body and an icebreaking mechanism arranged below the hatch cover. An opening and closing locking device is arranged on an inner surface of the hatch cover and is driven by a pair of opening and closing locking hydraulic cylinders to operate; the icebreaking mechanism is arranged on the supporting platform around the opening in the bottom of the access cabin and comprises a hydraulic lifting column, a shell and an icebreaking disc, wherein the hydraulic lifting column is installed on the supporting platform, the icebreaking disc is rotationally hinged to the shell, the hydraulic lifting column drives the shell and the icebreaking disc to be led out from the top of the access cabin to break an ice layer, and a plurality of icebreaking drills and hobs are arranged on the icebreaking disc. The ice breaking mechanism moves up and down to cut an ice layer, the ice breaking drill and hob combined structure is adopted for breaking ice from bottom to top, ice breaking efficiency is improved on the basis of the ice layer breaking mechanism, and the ice layer above the hatch cover is thoroughly smashed.

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...
