On-bottom and off-bottom supporting device for manned submersible

Abstract

The invention relates to an on-bottom and off-bottom supporting device for a manned submersible. The on-bottom and off-bottom supporting device for the manned submersible comprises an on-bottom and off-bottom supporting body which is connected with a pressure-resisting shell of the manned submersible through a body lifting cylinder. A body extension cylinder is installed between the pressure-resisting shell and the body lifting cylinder. The body extension cylinder extends or retracts to make the body lifting cylinder and the on-bottom and off-bottom supporting body to move away from or move close to the manned submersible. The on-bottom and off-bottom supporting body comprises a plurality of supporting rods installed between a lower base and an upper base. Supporting legs are hinged to the supporting rods through sliding blocks capable of sliding up and down. Supporting leg support plates are installed at the lower ends of the supporting legs, and the supporting legs are connected with the lower base through connecting rods. A supporting leg extension cylinder for driving the sliding blocks to slide up and down is installed between the upper base and the lower base. The supportingrods are of a hollow structure, water outlet holes are formed in the side walls of the supporting rods, and water inlets in the upper ends are connected with a water outlet of a deep water pump. Theon-bottom and off-bottom supporting device for the manned submersible is simple in structure, reliable in operation and convenient to install.

Description

AI Technical Summary

Problems solved by technology

If the submersible subsides at a large depth, it may not be able to leave the bottom normally due to the large adsorption force of the sediment during the process of leaving the bottom

In this case, the ballast water adjustment system of the manned submersible is usually used to make the hull quickly trim or heel to get rid of the mud bottom. Such a large adjustment of the attitude of the hull will affect the safety of the personnel and equipment in the boat.

In extreme cases, the rapid hull swing still cannot make the submersible get rid of the mud bottom, which will threaten the safety of the entire submersible
