Cable floating ball throwing device for submersible

Abstract

The invention discloses a cable floating ball throwing device for a submersible. Its storage box is fixed on the top of the submersible. The cable and the two floating balls that are not inflated are usually stored in the storage box. When recovering the submersible, the remote control or the crew operates the linkage cable to open the lid and trigger the electric ignition inflation device to complete the automatic inflation of the floating ball and float to the water surface. For small untethered submersibles, the thrown cable can be used to complete the recovery directly; for manned submersibles that cannot be recovered directly, the cable can be used to establish the initial connection between the submersible and the mother ship.

Description

A cable floating ball throwing device for a submersible technical field The invention belongs to the technical field of submersible recovery, and in particular relates to a cable floating ball throwing device for a submersible. Manned submersibles that cannot be recovered directly (such as untethered autonomous rescue submersibles, shuttle submersibles, etc.) establish an initial cable connection with the surface mother ship. Background technique The traditional mother ship recovery method is: after the submersible returns to the surface to support the mother ship after performing its mission, it is hooked to the mother ship by a small boat or a frogman on the sea surface to complete the recovery. For such a recovery method, the submersible rises and falls with the waves, and it is difficult to achieve precise coupling. This method can only be carried out under sea conditions below level 4, and cannot guarantee the safe, reliable and efficient recovery of submersibles. A...

Problems solved by technology

French patent document FR2 823 485 introduces a deployment and recovery system, which is a cage structure composed of an upper frame and a lower frame, and the upper and lower parts can move relatively vertically, thereby realizing the deployment and recovery of the submersible, but It is not suitable for submersibles with fragile external equipment on the outer surface (such as propulsion units or measuring instruments, etc.)

In addition, there is a method of using repeaters to complete the recovery of the submersible, at which time the size of the submersible and the form of the mother ship will be limited
