Bottom sitting device for manned submersible

Abstract

The invention discloses a manned submersible bottom resting device, which comprises a bottom resting bracket. The bottom resting bracket is of a frame-type structure, an upper layer slab and a lower layer slab are arranged in parallel and at intervals, arc structures are arranged at the two end sockets of the lower layer slab, a baffle is arranged between the upper layer slab and the lower layer slab, a buoyancy block is placed in a groove opening formed by the baffle, the upper layer slab and the lower layer slab, a device base is alternately mounted above the bottom resting bracket, the upper plane of the device base is a working platform, the cross section of the device base is of a Chinese word 'gong'-shaped structure, a plurality of concave pits are formed below the device base at intervals, the concave pits are connected with the device base in a matching mode through a damping mechanism, a bottom layer of the device base is bonded with a rubber pad, and a rubber pad is connectedwith the upper layer slab of the bottom resting bracket in a butt joint mode. The impact of the undersurface of sea on submersible during bottom resting is effectively reduced, shock is reduced, andsafety of the manned submersible and comfort of personnel inside a cabin are improved.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for submersibles, in particular to a device for sitting on the bottom of a manned submersible. Background technique [0002] When a manned submersible is operating on the seabed, it usually needs to sit on the bottom of the sea. After the submersible reaches the top of the operating site, the propeller is closed, and the negative buoyancy required by the submersible (the negative buoyancy is usually tens of kilograms) is provided to the submersible through the adjustable ballast tank, and the manned submersible is adjusted through the trim adjustment system. Sit down. [0003] In the prior art, manned submersibles usually use a bottom support welded on the lower surface of the submersible frame to provide support for the submersible when the submersible is sitting on the bottom. Due to the complex topography of the seabed and the flow field near the seabed, it is difficult to control...

AI Technical Summary

Problems solved by technology

Due to the complex topography of the seabed and the flow field near the seabed, it is difficult to control the submersible to sit on the bottom smoothly. The shock and vibration generated when sitting on the bottom is not conducive to the safety of the submersible, and at the same time reduces the comfort of the people in the cabin.
