[0002] With the continuous development of the oil and gas industry, the oil and gas pipeline network continues to improve. Due to the diversity of my country's geographical conditions, pipelines inevitably cross various rivers during the laying process, and pipelines crossing rivers are relatively prone to failure. Currently, there is little research on river oil spill recovery in my country. If oil spills occur in high-velocity rivers, if they are not promptly and effectively handled, they will lead to waste of resources and serious damage to the ecological environment.

[0003] Oil booms, as the primary device for oil spill recovery, play a vital role in many oil spill incidents. However, the current use of most oil booms is limited by geographical conditions. Conventional oil booms are only suitable for use in oceans and reservoirs with relatively gentle currents. They are ineffective in rivers with high currents and are easily damaged by the impact of currents, causing the oil to escape. Summary of the Invention

[0010] Furthermore, fixed baffles for mounting a rotating shaft may be provided at both the front and rear ends of the first and second freeboard surfaces.

[0011] Furthermore, the material of the roller may be PC plastic, and the roller may be cylindrical.

[0012] Furthermore, a floating body counterweight may be fixed to the lower portion of the hollow cavity of the floating body.

[0033] Hereinafter, the impact-resistant oil boom for intercepting oil spills in turbulent rivers of the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0034] Conventional oil booms are only suitable for use in oceans and reservoirs with relatively gentle water flow. When used in rivers with faster water flow, they cannot effectively block oil. Conventional oil booms are easily damaged by water flow, leading to oil spills.

[0035] To solve the above problems, the following exemplary embodiments of the present invention provide an impact-resistant oil boom for intercepting oil spills in turbulent rivers.

[0036] Exemplary embodiment 1

[0037] The following combination Figures 1 to 4 The invention will be used to describe the impact-resistant oil boom for intercepting oil spills in turbulent rivers.

[0038] like Figure 1 and Figure 2As shown, the impact-resistant oil boom for intercepting oil spills in rapid-flow rivers may include: a float 1, a damping device 2, a buffer rolling group, a connecting chain 4 and a counterweight chain 5.

[0039] The center of the interior of the floating body 1 is a hollow cavity (also called a hollow space).

[0040] The damping device 2 is installed in the hollow cavity of the floating body 1. When the impact force of the water flow and the wind force are large, the damping device 2 can effectively maintain the stability of the floating body 1 and reduce the failure rate of the oil boom.

[0041] The rolling buffer group is installed on the upper surface of the buoy. When the water flow in the working water area is strong, the rolling buffer group can reduce the impact force on the oil boom and maintain the stability of the oil boom in the water area.

[0042] The lower end of the buoy 1 is connected to a counterweight chain 5 via a connecting chain 4. The present invention utilizes the connecting chain 4 to save transportation space, reduce deployment difficulty, and mitigate the impact of water on the boom. The counterweight chain 5 also maintains the boom in an upright position during deployment, effectively intercepting oil spills.

[0043] In this embodiment, if Figure 1 and Figure 2 As shown, the longitudinal surface of the floating body 1 is in the shape of a water drop, which can lower the center of gravity of the floating body and enhance the stability of the oil boom in the water area.

[0044] In this embodiment, if Figure 2 As shown, a buoy counterweight 11 is installed below the interior of the buoy 1. This counterweight 11 is fixed (e.g., welded) to the buoy, effectively lowering the boom's center of gravity while maintaining its draft, thereby improving its stability in the water. The counterweight 11 allows the boom's lower portion to be submerged in the water, with the freeboard above the water surface, allowing the boom to intercept oil spills.

[0045] In this embodiment, if Figure 2 As shown, the upper surface of the floating body 1 includes two freeboard surfaces that are symmetrically distributed and connected to each other, and the angle between the two freeboard surfaces can be acute.

[0046] In this embodiment, if Figure 1 and Figure 2 As shown, the buffer rolling group may include a plurality of buffer rolling elements 31 mounted on two freeboard surfaces, and a first baffle 32 and a second baffle 33, for example Figure 2 There are twelve buffer rollers 31 in total, six on the left and six on the right.

[0047] The buffer roller 31 may include a rotating shaft 311 and a roller 312. A first baffle 32 and a second baffle 33 are vertically mounted at either end of the freeboard surface. The roller 312 may be cylindrical and connected to the two fixed baffles via the rotating shaft 311.

[0048] The material of the roller 312 can be PC plastic, which can keep the weight of the upper part of the oil boom at a low level while maintaining high strength, thereby maintaining the stability of the oil boom in the water area.

[0049] In this embodiment, the damping device 2 may include: Figure 3 The damping device 2 of the present invention can effectively maintain the stability of the floating body 1 when the impact force of the water flow or wind is large, reduce the failure probability of the oil boom, and improve the efficiency of oil interception.

[0050] In this embodiment, if Figure 1 As shown, the counterweight chain 5 is connected to the floating body 1 through the connecting chain 4, which can keep the floating body 1 in a vertical state during operation.

[0051] In this embodiment, adjacent anti-shock type oil booms are connected by Figure 4 The quick connector 61 is connected to the connector 62. The connector 62 may include a latch.

[0052] In summary, the advantages of the impact-resistant oil boom for intercepting oil spills in torrent rivers of the present invention may include:

[0053] (1) The impact-resistant oil boom of the present invention can be used in various waters and can resist both water flow impact and wind impact, thus overcoming the disadvantage of poor applicability of current conventional oil booms.

[0054] (2) The present invention is provided with rollers on the freeboard surface, which can reduce the impact force of water flow and wind on the impact-resistant oil boom used for intercepting oil spills in turbulent rivers, and can maintain the stability of the impact-resistant oil boom under adverse conditions.

[0055] (3) The present invention is equipped with a damping device inside the float. When the hydraulic impact force and wind force are large, the damping device can effectively reduce the shaking of the impact-resistant oil boom used for intercepting oil spills in torrent-type rivers, maintain the stability of the impact-resistant oil boom used for intercepting oil spills in torrent-type rivers, improve the oil interception efficiency, and buy time for oil recovery.

[0056] (4) The present invention solves the problem of poor applicability of conventional oil booms and proposes corresponding improvement measures to improve the applicability of oil booms.

[0057] Although the present invention has been described above with reference to the exemplary embodiments and the accompanying drawings, it will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the spirit and scope of the claims.
