Problems solved by technology

Oil booms are generally not restricted by the operating water depth and can be deployed in different sea areas. However, due to the continuous accumulation of wind waves and Enteromorpha, a large amount of Enteromorpha overflows from the top of the oil boom
In addition, the oil fence can only intercept Enteromorpha on the water surface, but cannot intercept Enteromorpha on the surface, which affects the interception effect
The pile block is limited to the shallow water area with a depth of several meters, which is inconvenient to operate and labor-intensive to install

Embodiment Construction

[0008] The net gear that the present invention is equipped with (see figure 1 ) is made up of floater, floater section 2, side section 3, fence 4 and sinker section 5 tied to iron chain 6, and floater is elongated rubber airbag 1, and rubber airbag 1 wall thickness is 2 millimeters, and the cross-sectional diameter of airbag after inflating 600mm. Every 500 meters rubber air bag 1 and block net 4 constitute an operation unit, the mesh length of block net 4 is 60 millimeters, and the net wire diameter is 2.6 millimeters, and net line material is polyethylene. The float-sink ratio of the air bag interception net is 14:1, which makes the air bag fully float on the water surface, and can effectively prevent Enteromorpha from overflowing from the top of the air bag when the wave height is 1.5 meters. The ratio of the length of the floater section 2 to the sinker section 5 is 1:0.98. The floater and the sinker produce component force due to the current flow in the operation, so tha...

Abstract

The invention discloses a method for arresting entermorpha with an air bag type arresting barrier, relates to offshore surface entermorpha arresting technology and aims to solve the technical problem of providing the method for arresting the entermorpha with the air bag type arresting barrier. The technical scheme adopted by the invention is that: the used barrier consists of a floater, a float line, a breast line, a fence net and a ground rope which is tied with an iron chain; the method is characterized in that the floater is a strip-shaped rubber air bag; the mesh wire diameter of the fence net is 2.6mm and the mesh length is 60mm; the float-sink ratio of the air bag type arresting barrier is 14 to 1; the length ratio of the float line to the ground rope is 1 to 0.98; the two ends of the air bag type arresting barrier are provided with drag rope connecting and mooring anchors; and during operation, the mooring anchor at one end of the air bag type arresting barrier is first dropped, the air bag type arresting barrier is arranged against the stream by stretching the mesh while inflating and finally the mooring anchor at the other end is dropped. The method is used for arresting the offshore surface entermorpha.

Description

Technical field: [0001] The invention relates to an interception technology of enteromorpha on the surface layer of offshore waters. Background technique: [0002] At present, to remove the Enteromorpha on the sea surface, two methods, passive or mobile, are used to intercept and salvage the Enteromorpha. The passive operation method adopts oil barriers or pile nets to intercept Enteromorpha, and blocks Enteromorpha flowing through the local sea area in the open sea, preventing and reducing environmental pollution caused by its flow into the offshore and shore. Oil booms are generally not restricted by the operating water depth and can be deployed in different sea areas. However, due to the influence of wind waves and the continuous accumulation of Enteromorpha, a large amount of Enteromorpha overflows from the top of the oil boom. In addition, the oil fence can only intercept Enteromorpha on the water surface, but cannot intercept Enteromorpha on the surface layer, which a...
