Problems solved by technology

During the long-term diving operation and maintenance process, it was found that there were problems such as high labor intensity and long opening and closing time in the opening and closing operation of the hatch cover, and the overall operation efficiency was low, especially when an accident occurred in the cabin and emergency evacuation was required. The escape time was seriously delayed due to the slow opening of the pressure hatch

Abstract

The invention relates to a fast and labor-saving opening and closing handle mechanism of a pressure-resistant hatch cover, comprising a pressure-resistant hatch cover, a connecting shaft is vertically installed in the middle of the pressure-resistant hatch cover, and a hand wheel is installed on the top of the connecting shaft, and the hand wheel includes a hand wheel body And the handwheel ring. The handwheel body is a columnar structure that matches the top of the connecting shaft. Several telescopic components that extend outward and pass through the handwheel ring are evenly distributed along the circumference of the handwheel body. Each telescopic component is installed inside to control the extension or Shortened latch assembly. The invention extends the force arm of the handwheel, reduces the operating force, accelerates the opening speed of the hatch cover, and reduces the risk; Corrosion of components and locking components reduces material performance requirements; telescopic components have no overhang phenomenon, reducing the possibility of hooking accidents and ensuring safe operation; the invention has low manufacturing cost and reliable performance, and can also be adapted to other hatch covers .

Description

technical field [0001] The invention relates to the technical field of hatch cover opening and closing, in particular to a fast and labor-saving opening and closing handle mechanism of a pressure-resistant hatch cover. Background technique [0002] The pressure-resistant hatch cover is an important equipment used in submarines, submersibles and other manned platforms to achieve watertightness and pressure. It plays an important role in situations such as emergency escape, so the convenience of opening and closing the pressure-resistant hatch cover is particularly important. During the long-term diving operation and maintenance process, it was found that the opening and closing operation of the hatch cover has problems such as high labor intensity and long opening and closing time, and the overall operation efficiency is low, especially when an accident occurs in the cabin and requires emergency evacuation. The escape time was seriously delayed due to the slow opening of the...
