Description

Technical Field

[0001] This utility model belongs to the technical field of barrier fabric, specifically relating to an oil-proof barrier fabric for marine operations. Background Technology

[0002] Barrier fabric is a flexible barrier material used for physical isolation, area demarcation, or security protection. It is usually made of polymer or glass fiber as the base material and is produced through weaving, coating, or composite processes. It has properties such as UV resistance, weather resistance, flame retardancy, water resistance, and tear resistance. It is widely used in construction site fencing, temporary road isolation, forest firebreaks, event site demarcation, and medical environment isolation, etc., to achieve the purpose of space management, security protection, or environmental protection by forming physical barriers.

[0003] The announcement number CN211773455U describes a barrier and collection platform device for marine oil spill treatment. The barrier can be connected end-to-end to form a blockade based on the extent of oil spill pollution, thus facilitating the isolation of the oil spill and preventing it from causing further pollution. This helps limit the scope of oil spill pollution and facilitates subsequent collection and treatment. Although this technical solution includes counterweights, the floating objects on the sea surface are too low, making it easy for seawater to overflow them under the influence of wind and waves, leading to oil leaks. Furthermore, while the solution includes a barrier membrane, this membrane is underwater and cannot function on the water surface, resulting in only a moderate oil-repellent effect. Utility Model Content

[0014] The following are specific implementation cases and appendices. Figures 1-4 This utility model will be further described, but it is not limited to these embodiments. This utility model provides a technical solution: an oil-proof barrier fabric for marine operations, comprising: a barrier fabric body 1, a fabric support structure installed inside the barrier fabric body 1, a connecting structure installed on the side wall of the fabric support structure, and two sets of center-of-gravity shifting structures installed on the lower wall of the fabric support structure; the fabric support structure includes: a fabric support base 2, a fabric support upright plate 3, two support nuts 4, two support screws 5, and a support clamping plate 6; the fabric support upright plate 3 is installed on the upper wall of the fabric support base 2, and the two support nuts 4 are respectively embedded in the lower wall of the fabric support base 2. Each support screw 5 is movably installed inside the support nut 4 via a thread. The support clamp 6 is fixedly installed on the lower wall of the fabric support base 2 via two support screws 5. The partition fabric body 1 is wrapped around the fabric support base 2 and the fabric support upright 3, and both ends of the partition fabric body 1 are clamped between the fabric support base 2 and the support clamp 6. Sealing zippers 15 are installed on the two side walls of the partition fabric body 1. The exterior of the partition fabric body 1 is coated with an oil-repellent coating. Two anti-slip rubber strips 16 are installed on the lower wall of the fabric support base 2 and two anti-slip rubber strips 16 are installed on the upper wall of the support clamp 6. Two buoyancy columns 17 are installed inside the fabric support base 2.

[0015] As a preferred embodiment, the connection structure further includes: a connecting female buckle 7, a connecting seat 8, a connecting rope 9, and a connecting male buckle 10; the connecting female buckle 7 is installed on the side wall of the fabric support plate 3, the connecting seat 8 is installed on the other side wall of the fabric support plate 3, one end of the connecting rope 9 is installed on the side wall of the connecting seat 8, and the connecting male buckle 10 is installed on the other end of the connecting rope 9.

[0016] As a preferred embodiment, the two sets of center-of-gravity lowering structures further include: a center-of-gravity fixing nut 11, a center-of-gravity fixing screw 12, a center-of-gravity connecting cable 13, and a center-of-gravity hammer 14; the center-of-gravity fixing nut 11 is embedded inside the support clamp 6, the center-of-gravity fixing screw 12 is movably installed in the center-of-gravity fixing nut 11 by means of threads, one end of the center-of-gravity connecting cable 13 is installed on the lower wall surface of the center-of-gravity fixing screw 12, and the center-of-gravity hammer 14 is fixedly installed on the other end of the center-of-gravity connecting cable 13.

[0017] Working principle: This device cannot be used alone. Several devices need to be connected to form a chain and placed on the sea surface to enclose the area where the operation is being carried out at sea. If an oil spill occurs during the operation at sea, it can ensure that the oil is confined to the area and does not spread, thus providing preventive protection for the marine environment.

[0018] The operator first covers the partition fabric body 1 over the fabric support base 2 and the fabric support upright plate 3. Then, the support clamp 6 is fixed to the lower wall of the fabric support base 2 by two support screws 5, so that both ends of the partition fabric body 1 are fixed between the fabric support base 2 and the support clamp 6. Anti-slip rubber strips 16 are provided between the partition fabric body 1 and the fabric support base 2, and between the partition fabric body 1 and the support clamp 6. The anti-slip rubber strips 16 can increase the friction and thus ensure the stability of the partition fabric body 1.

[0019] When connecting multiple devices, the operator first inserts the connecting buckle 10 into the connecting nut 7, allowing several fabric support uprights 3 to be connected in series via the connecting rope 9, thus forming a series of partition fabric chains with multiple fabric support bases 2 and fabric support uprights 3. Next, the operator connects the partition fabric body 1 via the sealing zipper 15, thereby forming a single, elongated partition fabric body 1.

[0020] Operators use a transport ship to lower the assembled barrier fabric bodies 1 into the sea. Both the fabric support base 2 and the fabric support uprights 3 are made of polyethylene and have a hollow structure, allowing for stronger buoyancy. To achieve stable buoyancy, buoyancy columns 17 are installed inside the fabric support base 2. The fabric support base 2 and fabric support uprights 3 will float on the sea with the barrier fabric bodies 1. Then, driven by the center of gravity hammer 14 through the center of gravity connecting cable 13, a portion of the fabric support base 2 sinks into the seawater, and a portion of the barrier fabric bodies 1 sinks into the seawater, thus creating a situation where part of the barrier fabric bodies 1 is submerged and part is exposed above the seawater.

[0021] Under the gravitational pull of the center of gravity 14 and the buoyancy of the cloth support base 2, cloth support plate 3 and buoyancy column 17, part of the partition cloth body 1 can be submerged in the seawater and part of it can be exposed above the seawater. If waves hit the device, the partition cloth body 1 can still maintain this position, thus preventing oil leakage in the area.
