A trim adjustment and emergency throwing mechanism

Abstract

The invention discloses a trim adjusting and emergency throwing mechanism, which comprises a bow drum, a bearing seat, a base, a rotating shaft, a stern drum and a chain. The bow drum is positioned near the bow of the underwater vehicle, and the stern drum is positioned near the stern of the underwater vehicle. The number of the rotationg shaft is two, which are located at the bow and the stern ofthe underater vehicle respectively; The bow drum and the stern drum are respectively rotated around the corresponding rotating shaft; The rotating shaft is arranged on the base through a corresponding bearing seat; The chassis is of a frame structure with no shelter in the middle and is used for throwing load; The chain is respectively wound on the bow drum and the stern drum, the winding direction of the chain on the bow drum is clockwise, and the winding direction on the stern drum is counterclockwise. This mechanism not only realizes the mass transfer, but also fulfills the demand of emergency unloading, and has little impact on the environment.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, relates to emergency equipment, and in particular relates to a trim adjustment and emergency load dumping mechanism. Background technique [0002] Underwater vehicles, including manned submersibles and unmanned submersibles, need to perform longitudinal attitude adjustment when necessary, which is called trim adjustment. For example, when diving, it is hoped that the bow is inclined downward to speed up the diving speed. At this time, the trim adjustment mechanism needs to move the heavy object to the bow; for another example, if the bow sampling basket is loaded with samples, the bow and stern are unbalanced. , at this time, the trim adjustment mechanism needs to move the weight to the stern. [0003] The following problems exist in the prior art: [0004] (1) Traction technology for large-mass objects such as batteries: Pull large-mass objects such as batteries back and forth to a...

AI Technical Summary

Problems solved by technology

The problem is: firstly, the cavity space required for adjustment is large, which is not easy to realize in the submersible; secondly, the inertia of large-mass objects such as batteries is relatively large, and it is difficult to discard them as emergency ballast if the bottom frame is used; Suspension method, in the process of traction and snorkeling, it is very easy to shake and hit the frame of the hull to cause damage

The problem is: the system is complex, and mercury is volatile, corrosive, toxic, and difficult to maintain; if it is directly released into seawater as emergency ballast, it will cause harm to the environment

The problem is: the density of seawater is small, so the adjustment ability is weak, and the viscosity of seawater is small. When it is in deep and high-pressure seawater, the self-leakage is serious and the adjustment speed is slow.
