A seabed dust and sediment suppression device

Abstract

A seabed dust and sediment suppressing device, comprising a rubber water bladder, a strut assembly is installed inside, the strut assembly can be expanded and retracted, and the rubber water bladder is simultaneously deployed and retracted along with the expansion and retraction of the strut assembly; The structure of a single strut assembly is as follows: it includes four connecting pieces distributed at intervals, the upper surface of a single connecting piece is smooth, the lower surface is fixed with a cross-shaped connecting pipe, and the upper surfaces of the two connecting pieces arranged diagonally face upward , the upper surfaces of the other two diagonally arranged connectors face downward, and the cross-shaped connecting pipes on the connectors are hinged with rigid hollow struts. A total of twelve rigid hollow struts are hinged with four connectors to form a "well" In the font structure, flexible water pipes are arranged inside each rigid hollow strut, and the flexible water pipes communicate with each other inside the cross-shaped connecting pipe, and four flexible water pipes protrude from the outside of the rubber water bladder. Ensure the clarity of the seawater environment when the submersible operates near the seabed and sits on the bottom, and improves operating efficiency.

Description

technical field [0001] The invention relates to the technical field of suppressing devices, in particular to a submarine dust and sediment suppressing device. Background technique [0002] With the acceleration of human understanding and development of the deep sea, a large number of manned and unmanned submersibles have been used in deep sea exploration, resource development, scientific investigation and other tasks. [0003] Among them, most of the current seabed terrain detection, seabed resource development and scientific investigation activities of human beings are basically concentrated on the seabed and the seabed. [0004] In addition, the deep seabed is a dark environment. Both manned and unmanned submersibles need to be equipped with high-brightness underwater lights and cameras to observe the underwater environment. [0005] The seabed and near-seabed currents are very small, similar to the still water environment, and most of the seabed is attached with a large ...

AI Technical Summary

Problems solved by technology

[0006] When the submersible is sitting on the bottom or navigating near the bottom of the sea, its propeller will stir up the sediment and sand on the bottom of the sea, which will greatly reduce the visibility of the nearby sea water.

However, due to the approximate still water environment, the diffusion conditions of turbid seawater are very poor, and it often takes several weeks for the seawater to return to clarity.

This caused great trouble for the submersible's optical equipment to observe the surrounding environment, and even led to the failure of the mission
