Embodiment Construction

[0018] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0019] see figure 1 , figure 2 , The present invention includes ballast 1, the upper part of ballast 1 is fixed with lifting lugs 2, and the underwater equipment body is fixed with a mounting frame 3 through screws 9. The mounting frame 3 includes ear plates 301, lifting lugs 2 and ear plates 301 Each is provided with a through hole for the plunger 4 to pass through and slide; a cylinder block 5 is fixedly mounted on the mounting frame 3, and the cylinder block 5 has a hollow cavity with an opening at one end, and one end of the plunger 4 is inserted through the opening. Said hollow cavity, and the plunger 4 and the hollow cavity are sealed by a seal 6 which usually adopts an O-ring seal. The sealed hollow cavity is pre-filled with internal pressure, and the cylinder block 5 and The plunger 4 is connected by a positioning pin 7. The positioning pin 7 preferably us...

Abstract

The invention provides a deep sea self-induction emergency load rejection mechanism. The mechanism comprises a ballast, wherein a lifting lug is fixedly arranged at the upper part of the ballast; an installation rack is fixedly installed on a subsea equipment body and comprises lug plates; through holes for passing and sliding of a plunger are formed in the lifting lug and the lug plates; a cylinder block is fixedly installed on the installation rack and is provided with a hollow cavity with an opening in one end; one end of the plunger is stuffed in the hollow cavity; the plunger and the hollow cavity are sealed by sealing elements; the sealed hollow cavity is pre-filled with internal pressure; the cylinder block and the plunger are connected by a locating pin; the other end of the plunger passes through the through hole of the lifting lug and the through holes of the lug plates; under the actions of the internal and external pressures of the sealed hollow cavity, the plunger is connected with the through hole of the lifting lug or breaks away from the through hole of the lifting lug so that the ballast is connected with the installation rack or breaks away from the installation rack. The mechanism achieves automatic load rejection through self induction of internal and external pressures.

Description

Technical field [0001] The invention relates to the technical field of underwater dumping, and in particular to a mechanism for dumping used on underwater equipment such as submarines or submersibles by automatically sensing external seawater pressure. Background technique [0002] In order to improve the safety of the underwater equipment, especially the safety of the staff in the underwater equipment, it is usually necessary to be equipped with an emergency dumping device. When the underwater equipment is in an emergency, the dumping device is triggered to throw off the ballast weight, so that The underwater equipment is in a state of positive buoyancy, so it can surface safely, waiting for the rescue of the surface vessel. [0003] At present, the emergency dump mechanism on the submarine or submersible is generally triggered in the following ways: the cabin personnel are manually operated through the mechanical mechanism through the pressure cabin; the cabin personnel operate t...
