Movable ocean floating object interception dredging net and using method

Abstract

The invention discloses a movable ocean floating object interception dredging net and a using method. The main body of the movable ocean floating object interception dredging net is a rectangular net made of a polymer material. Floating balls and sunken blocks are arranged on an upper net rope and a lower net rope correspondingly so that the interception dredging net can be supported tightly upwards and downwards, and the relatively-stable rectangular shape is kept. Aerator pipes are arranged on the lower net rope or at the position deep in the water away from the water surface by 10m. A side net rope inflation pipe is used for aeration. The lower net rope is provided with two high holding power anchors. The interception dredging net can be arranged in the ocean at will by adjusting the arrangement positions of the high holding power anchors, the optimal interception dredging effect or the interception dredging net arrangement angle, length and sensitive protected object distance meeting the actual production needs can be obtained, and the interception dredging net can be adjusted and optimized at any time according to the ocean current direction change condition. Multiple nets can be connected in series for use, the movable ocean floating object interception dredging net is used for interception dredging or interception capturing of ocean floating objects manually or naturally, adjustment and optimization can be made at any time according to the actual situations, the optimal interception dredging effect can be maintained and the application prospects are good.

Description

technical field [0001] The invention belongs to the field of interception, dredging and clearing of marine floating objects, and relates to a movable intercepting and dredging net of marine floating objects and a use method, which can be used for the management of marine ecological environment. Background technique [0002] There are often various floating and suspended objects in the ocean, man-made, such as plastics and other floating garbage; there are also natural ones, such as enteromorpha, jellyfish and other floating plants and animals. When these natural or man-made floating objects gather in piles, especially when natural floating objects break out, they often cause disasters to coastal socio-economic production and human activities. For example, when Enteromorpha and jellyfish break out, they will affect the beauty of the coastal landscape and pollute seawater. Bathing places, blockage of various seawater engineering pipelines, etc., and even dangerous incidents of...

Problems solved by technology

The difficulty mainly has two aspects. First, marine engineering such as artificial structures is expensive and has a huge amount of engineering. Because of some worthless marine floating debris, the construction of arduous and huge marine dredging dams is often not worth the candle.

Secondly, even if such a fixed marine floating debris diversion dam is successfully built, it is still difficult to cope with the rapidly changing nearshore flow field environment in the ocean

The nearshore ocean current field often changes with the wind field, seasons and other factors. The marine floating debris diversion dams of fixed buildings are likely to work well under certain conditions, but in other seasons or weather conditions due to changes in the flow field ineffective, or even negative
