Rapid positioning and locking device of plugging umbrella

Abstract

The invention relates to a rapid positioning and locking device of a plugging umbrella. The rapid positioning and locking device comprises an umbrella body and an umbrella rod. The rapid positioning and locking device is characterized in that the rapid positioning and locking device is connected to the umbrella rod in a sleeving manner; the rapid positioning and locking device comprises a connecting-rod aligning mechanism, a ratchet positioning mechanism and a spiral locking mechanism, wherein the connecting-rod aligning mechanism comprises a plurality of push rods, a plurality of supporting rods, a front sliding ring and a rear sliding ring; the push rods are separately hinged to the front sliding ring; the supporting rods are separately hinged to the rear sliding ring; each push rod is hinged to the corresponding supporting rod; the push rods are uniformly distributed at the periphery of the umbrella rod; the front sliding ring and the rear sliding ring are mounted on the umbrella rod in a sleeving manner; the front sliding ring is fixedly connected with an umbrella cover supporting rod slide hub of the umbrella body; the ratchet positioning mechanism and the spiral locking mechanism are connected to the umbrella rod in a sliding manner. The rapid positioning and locking device has the benefits that the rapid positioning and locking device disclosed by the invention adopts the connecting-rod aligning mechanism, and the plugging umbrella is led to rapidly align with the center of a hole of a ship body by utilizing a wedge shape principle, so that the problem that the plugging umbrella cannot align with the center of the hole and adjust a plugging position under large rapid flow is solved.

Description

technical field [0001] The invention belongs to the field of leak plugging of ships, and in particular relates to a rapid positioning and locking device for leak plugging umbrellas capable of quickly aligning and locking the leak plugging umbrellas. Background technique [0002] Ship plugging is to use various plugging equipment and tools to seal the breach after the hull is damaged, so as to control the damage degree of the ship after damage and maintain the buoyancy of the ship. It is an important content of ship damage control. The leak-stopping umbrellas that have appeared in recent years can perform outboard leak-stopping operations in the cabin, and can press the umbrella cover tightly on the hull with the help of seawater pressure. It has the characteristics of fast expansion and retraction, and good sealing effect, and has been widely used. application, and has formed a series of products. There are mainly two kinds of plugging umbrella positioning and locking devic...

AI Technical Summary

Problems solved by technology

The common problem of these two positioning and locking mechanisms is that it is difficult for the umbrella rod to align with the center of the breach under the impact of seawater pressure and water flow when plugging the leak, resulting in an increase in the time for seawater to enter the cabin and a relatively long locking time. Affect the rapid implementation of plugging operations and the actual plugging effect
