Problems solved by technology

However, for torrent-type rivers with a flow velocity exceeding 2kn (1kn=0.514m / s), conventional oil booms are prone to structural failure under the impact of torrents, resulting in oil booms carrying and escaping oil, splashing oil, and leaking oil. In case of failure
[0003] At present, oil booms that are common in the market reduce the resistance of the oil boom by improving the skirt structure, such as nylon mesh ropes and filter blades, but at the same time reduce the effective interception area of ​​oil spills and reduce the efficiency of oil containment; in addition, Torrent rivers often carry impurities such as sediment and gravel, which can easily block the blades or damage the rope structure at high flow rates. Therefore, how to effectively maintain the structural stability of the oil boom and realize oil recovery under torrent conditions has become an engineering problem. , the present invention provides a folding grid oil boom and its deployment method for torrent rivers

Embodiment 1

[0036] Please refer to figure 1 , figure 2 , the size parameters of the oil boom are shown in Table 1.

[0037] Table 1

[0038]

[0039] When torrent rivers such as the Nujiang River and the Lancang River have an oil spill accident, the engineering vehicle will transport the oil fence and the grid to the site deployment point at the same time.

[0040] Utilize the deployment method of the folded mesh grid oil boom to deal with the torrent river of the present embodiment, comprise the following steps:

[0041] 1) First, the expansion bag 9 filled with SAP water-absorbent resin fibers 10 is connected to the middle layer skirt connecting cloth 4 through the threaded hole of the connecting piece 5;

[0042] 2) Then take out the aluminum alloy mesh plate 7, pass its upper end through the threaded hole 6 of the connecting piece 5, and connect with the front and rear two layers of skirt body connecting cloth 4 respectively;

[0043] 3) Put the oil boom into the river, and af...

Embodiment 2

[0046] In this embodiment, the structural design is adjusted under the condition that the main components are the same, please refer to image 3 , Figure 4 Similar to Example 1, it also includes skirt connecting cloth 4, connecting piece 5, aluminum alloy mesh panel 7, SAP water-absorbing resin fiber 10, floating body fixing anchor 11 and other main components. The difference is that the middle layer skirt connecting cloth 4 size Lengthen, increase the circular grid in the lower half, shorten the size of the front and rear two layers of skirt body connecting cloth 4; cancel the expansion bag 9 at the same time, install SAP water-absorbing resin fiber 10 in the middle layer of skirt body connecting cloth 4 and connect the front and rear two layers of skirt body Between the cloth 4, the bottom is connected with water-absorbing stretchable fiber cloth 13.

[0047] In this embodiment, the size parameters of the oil containment boom are shown in Table 2.

Abstract

The invention particularly provides a folding mesh oil containment boom for coping with torrent rivers and a laying method of the folding mesh oil containment boom, and belongs to the field of oil containment booms. The folding mesh oil containment boom aims at solving the problem that under current torrent type water area working condition, a common structure in the oil containment boom application technology fails. The folding mesh oil containment boom comprises components such as floating bodies, floaters, outer wrapping cloth, skirt body connecting cloth, connecting pieces, aluminum alloymesh plates, expansion bags, SAP water-absorbent resin fibers, floating body fixing anchor seats and mesh fixing anchor seats, the skirt body structure of a traditional oil containment boom is partially replaced with the aluminum alloy mesh plates, the water circulation amount is increased, the near-body flow speed of the oil containment boom is reduced, and stress of the oil containment boom is reduced, and therefore, the steady state of the oil containment boom is maintained; the aluminum alloy mesh is automatically expanded through expansion of a water absorption material to form double meshes, so that the spilled oil interception efficiency is improved; an oil absorption felt wrapped by the aluminum alloy mesh can further reduce failure loss caused by spilled oil entrainment. In the background of rapid development of the current petroleum transportation industry, the folding mesh oil containment boom has capacity of coping with the torrent river spilled oil interception, and has high market competitiveness.

Description

technical field [0001] The invention belongs to the field of oil booms, and in particular provides a foldable grid oil boom for torrent rivers and its deployment method Background technique [0002] Every year due to sudden oil spill accidents, the oil flowing into rivers and oceans has exceeded 500×10 4 Ton, the oil boom is widely used in the market for oil spill accidents in water areas. It plays the role of preventing the spread of oil spills, reducing the area of ​​oil spills, and cooperating with oil spill recovery. However, for torrent-type rivers with a flow velocity exceeding 2kn (1kn=0.514m / s), conventional oil booms are prone to structural failure under the impact of torrents, resulting in oil booms carrying and escaping oil, splashing oil, and leaking oil. In case of failure. [0003] At present, oil booms that are common in the market reduce the resistance of the oil boom by improving the skirt structure, such as nylon mesh ropes and filter blades, but at the s...
