Emergency load rejection mechanism of deep-sea manned submersible

Abstract

Provided is an emergency load rejection mechanism of a deep-sea manned submersible. The emergency load rejection mechanism of the deep-sea manned submersible comprises a rotary shaft, wherein the rotary shaft penetrates through a pressure-resistant spherical shell cabin, a hand lever is inserted into the upper end of the rotary shaft, the middle of the rotary shaft is installed in a shaft sleeve through a shaft sealing device, the shaft sleeve is arranged under the pressure-resistant spherical shell cabin, a ballast hanging protruding claw wheel is installed at the lower end of the rotary shaft, the ballast hanging protruding claw wheel is inserted into a hole in the top surface of a ballast block, and hanging is achieved; two guiding slide ways are formed in each of the four vertical planes of the ballast block so that the ballast block can be smoothly rejected under the conditions of different inclined postures of the deep-sea manned submersible. According to the emergency load rejection mechanism of the deep-sea manned submersible, an operator directly rotates the T-shaped hand lever to reject the emergency ballast block so that the deep-sea manned submersible can obtain enough buoyancy to upwards float to the water surface in emergency, the problem that when a control system has a failure, a submersible cannot reject ballast block to upwards float is solved, and it is ensured that the manned submersible can return safely.

Description

technical field [0001] The invention relates to a manned submersible, in particular to an emergency dumping mechanism for a deep-sea manned submersible. It belongs to the field of offshore oil engineering. Background technique [0002] Existing deep-sea manned submersibles are provided with manned spherical pressure-resistant cabins, which are also equipped with ballast water tanks, other buoyancy containers, and electronic control or hydraulic systems for manipulating deep-sea manned submersibles; the setting of pressure-resistant cabins It is to ensure the safe work of drivers and equipment. Manned submersibles must consider the emergence of emergencies, such as: ballast tanks or other buoyant containers are damaged and cannot drain water; electronic control or hydraulic systems fail, and the submersible cannot be controlled to obtain sufficient positive buoyancy so that the submersible cannot be underwater. In the dangerous state of return, the submersible can obtain en...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and provide an emergency dumping mechanism for a deep-sea manned submersible, which can directly rotate the T-shaped hand lever by the operator and throw the emergency ballast block, so that In an emergency, the submersible has enough buoyancy to float to the surface, which solves the problem of being unable to float when the control system fails
