AI Technical Summary

Technical Problem

The existing water intake devices of deep-sea aquaculture vessels lack effective solutions in terms of corrosion resistance and resistance to lateral ocean current impact, making it difficult to meet the dynamic adjustment requirements of large pipelines.

Method used

The telescopic mechanism, composed of multiple steel and plastic composite connectors and multiple sets of guide roller assemblies, is designed as a rigid structure. It achieves vertical movement through cable drive, adapting to the deep-sea environment and maintaining its smoothness.

Benefits of technology

It enables efficient and economical water supply in deep-sea environments, adapts to highly corrosive deep-sea conditions, avoids pipeline deformation, and is suitable for large-scale water diversion equipment.

Abstract

The telescopic water-drawing device of this utility model belongs to the fields of aquaculture and marine engineering. The telescopic water-drawing device consists of a telescopic mechanism composed of multiple steel and plastic composite connectors, supplemented by multiple sets of guide roller assemblies, to solve the problems existing in the prior art. It includes a fixed section assembly, at least one set of intermediate connecting assemblies, and a third section assembly. The fixed section assembly has a hollow first frame tube, with an array of auxiliary welded pipes welded around its interior. A first plate and a second plate are respectively provided at both ends of the first frame tube. The first frame tube, the array of auxiliary welded pipes, the first plate, and the second plate are welded together to form a hollow rigid structure. A first water pipe is sleeved at the axial center of this rigid structure. The third section assembly includes a second guide roller assembly connected to the intermediate connecting assembly, a second water pipe, and a fifth plate. The bottom of the second water pipe is connected to a corrugated pipe through the fifth plate, and its top is fixedly connected to the second guide roller assembly.
