A damping buffer for submersible deployment and recovery operations

Abstract

The invention provides a damping buffer for submersible deployment and recovery operations, comprising a cylinder head (1), a disc spring washer (2), two disc spring guides (3), two guide bearings (4), a stopper Dynamic adjustment washer (5), guide rod bushing (6), cylinder assembly (7), disc spring guide one (8), guide bearing one (9), guide bushing (10), guide rod (11) , sealing ring (12), disc spring one (13) and disc spring two (14), it is characterized in that, in the uncompressed initial position of damping buffer, the annular boss right side of disc spring guider two (3) The surface is blocked by the left end surface of the stop adjusting washer (5), the right end surface of the guide ring of the disc spring guide one (8) is blocked by the left end surface of the guide bushing (10), at this time the disc spring one (13), the disc spring Two (14) have pre-compression force, and the guide cylinder of disc spring guide one (8) stretches out outside the right end of guide bushing (10). The damping buffer of the present invention adopts a buffering structure of a two-stage disc spring, has strong buffering and vibration-absorbing capabilities, and is suitable for buffering and anti-swinging in deployment and recovery of manned submersibles under severe sea conditions.

Description

technical field [0001] The invention belongs to the technical field of deployment damping and buffering of marine engineering equipment, and in particular relates to a damping buffer used for deployment and recovery of submersibles. Background technique [0002] Manned submersibles mainly perform tasks such as underwater investigation, geological exploration, sample collection, pipeline maintenance, salvage and lifesaving. In deep diving operations, the deployment and recovery of manned submersibles is an important workflow. During this process, the submersible will be affected by the sea conditions in the operating area and produce sway and impact, which seriously threatens the safety of the submersibles and increases the work intensity of the operators. Therefore, buffer dampers are generally arranged between the submersible and the deployment device to reduce the impact of environmental loads on the system, improve the environmental adaptability and reliability of the de...

Problems solved by technology

[0003] In the prior art, the hydraulic buffer damper is mainly used, its structure is complex, the reliability is low, and the hydraulic oil pollution has a great impact on the marine environment

However, the conventional helical spring type buffer damper generally uses a spring with a large rigidity when the stroke is very short, and when the spring stroke is long, the stiffness is very small, which is difficult to meet the high-intensity and large-stroke impact environment of the deployment and recovery of manned submersibles.

According to domestic and foreign literature, there is no purely mechanical buffer damper suitable for the deployment and recovery of manned submersibles in the prior art
