Description

Oil trap

The present invention relates to an oil retaining rope, and more specifically, the present invention relates to an oil retaining rope that can be easily stored, transported, and provides sufficient strength.

Oil traps are usually used to contain oil spills floating on the oceans and rivers to prevent the oil area from continuing to spread, polluting the environment and harming organisms. There are inflatable, solid-filled, permanently fixed, etc., and various types are suitable for different fields. For example, rivers use inflatable type, and harbors use solid-filled types. In addition, there are offshore types and beach types. Insufficient; among them, the more widely used is the inflatable oil-retaining rope. Its advantage is that it is lighter than other forms, and the disadvantage is that it is easy to malfunction and breakage. Although it is still portable, it cannot be handled, operated, or deployed by one person. The crux of the problem is that the way of traction and connection between each single oil-retaining rope has never changed. This limit has reduced the direction of lightweighting of the oil-retaining rope. Instead, various chains and steel ropes have been added to the oil-retaining rope to strengthen the tension. It has become heavier and must be carried in large vehicles, and its deployment must also rely on special machinery.

Figure 1 shows a schematic diagram of a conventional oil trap. As shown in the figure, the oil retaining rope 9 is connected end to end by several airbags 910 to form an elongated rope with a length of tens to hundreds of meters. Therefore, the oil-retaining cable 9 will produce a great load-bearing pulling force when towing in the water. Traditional oil-retaining cables are not covered with reinforced plastic or artificial rubber. When the oil-retaining cable 9 extends to hundreds of meters, a pulling force of hundreds of kilograms will be generated. At this time, the plastic/rubber-coated material on the surface of the oil-retaining cable 9 will be easily broken. In addition, the conventional oil interceptor 9 is usually provided with a metal clamping plate 920 at both ends, and then the steel clamp 950 is respectively connected to the upper and lower ends of the metal clamping plate 920 and the fixed piles on the shore (not shown) to connect both ends of the oil interceptor 9 Fixed on the shore, under the pulling force of hundreds of kilograms, the connection between the plastic/rubber coating material on the surface of the oil retaining rope 9 and the metal splint 920 is more likely to tear.

In addition, the oil-retaining cable can effectively intercept oil leakage, and usually needs to stand upright in water. Therefore, weights and ballasts are required at the bottom of the oil interceptor to prevent the oil interceptor from tipping or overturning due to the impact of water flow. In order to meet the aforementioned requirements, a steel cable (or chain) 930 is added to the upper edge of the oil retaining rope, and a steel cable (or chain) 940 with a counterweight is provided at the lower edge of the oil retaining rope.

Many changes and modifications can be made within the scope of the invention without departing from the spirit of the invention, and the invention includes all such modifications.

FIG. 2 is a schematic diagram of the oil retaining rope of the present invention. As shown in the figure, the oil retaining rope 1 of the present invention has a plurality of airtight hollow capsules 100. The hollow capsule 100 is mainly made of, but not limited to, nylon cloth material, and the hollow capsule 100 can contain air, One side of each hollow bladder 100 is connected to one side of the other hollow bladder 100 in such a manner that air inside the bladder 100 does not circulate with each other, thereby forming a long oil trap 1. Each hollow bladder 100 is provided at its top with a piercing portion 110 isolated from the air inside the bladder 100, and a skirt 120 is provided at the bottom end from the air inside the bladder 100, and each hollow bladder 100 is provided with There is an air valve 200 so that air can enter or leave the hollow capsule 100 through the air valve 200.

The oil-retaining cable 1 of the present invention further has a towing cable 300, which respectively penetrates the penetrating portion 110 at the top of each hollow capsule 100 to connect all the hollow capsules 100 in series, and the connection strength between the hollow capsules 100 is mainly It is provided by the towing cable 300. The towing cable 300 may be, but not limited to, a nylon rope or a high density polyethylene rope (HMPE). Preferably, the nylon rope may be heat-treated before use to reduce its ductility. As shown in FIG. 3, on the towing cable 300, corresponding to the penetrating portions 110 at the top of each hollow balloon 100, an intermediary gluing portion 310 is respectively looped. The intermediary gluing portion 310 may be, but not limited to, rubber The material is glued (such as hot glued) to the towing cable 300 and fixed, and the intermediary glue part 310 is also glued (such as hot glued) to the corresponding hollow part 100 of the hollow body 100 to be fixed, so that the towed cable 300 It is fixed in each penetrating portion 110 of each hollow capsule 100 by an intermediary glue portion 310. When the oil-retaining cable 1 is operated in water, the water resistance caused by the water flow hitting the oil-retaining cable 1 and the tension generated by the weight of the oil-retaining cable 1 are mainly borne by the towing cable 300, so as to avoid hollows The capsule 100 is pulled and ruptured.

As shown in FIG. 4, the skirt 120 of the hollow capsule 100 is provided with a plurality of hanging holes 121 arranged in parallel, and each hanging hole 121 hangs a weight 400 (such as a metal block). When the oil retaining rope 1 floats on the water surface, the weight 400 can control the area of the hollow bladder 100 submerged in the water. For example, if the area where the hollow bladder 100 is to be submerged in water is large, the oil retaining rope 1 can hang a heavy weight 400. Conversely, if the area where the hollow bladder 100 is to be submerged in water is small, the oil retaining rope 1 hangs the lighter weight 400. During storage or transportation, the oil retaining rope 1 can also remove the weight 400 from the hanging hole 121, so that the hollow bladder 100 can be stored independently. In addition, the weight 400 can also control the positioning of the hollow bladder 100 relative to the water surface, which means that the weight 400 can keep the hollow bladder 100 positioned at an angle substantially perpendicular to the water surface, so as not to be dumped due to the impact of water flow or Tumble to ensure oil blocking effect. In addition, the oil trap 1 of the present invention also changes the load distribution of the tensile force on the traditional oil trap. The traditional oil trap is affected by its structure, and the tensile force is concentrated in its axial direction. On the other hand, in addition to withstanding the axial tensile force, the oil trapping cable 1 of the present invention changes part of the load to bear perpendicular to the axial direction to disperse the original concentrated tensile force.

As shown in FIGS. 5, 6 and 7, the gas valve 200 of the present invention includes a housing 210. A vent hole 220 is provided in the housing 210, and a check valve body 230 is penetrated through the vent hole 220. One end of the check valve body 230 extends into the hollow bladder 100 and forms a sealed end 231, and the other end of the check valve body 230 is provided with a biasing element 240 (such as a spring) to form a valve port end 232, which biases The element 240 provides a biasing force to the check valve body 230, so that when no external force is applied, the sealing end 231 of the check valve body 230 abuts the housing 210 of the air valve 200 to close the vent hole 220, thereby sealing the hollow bladder The body 100 prevents air from entering the hollow capsule 100 or escaping from the hollow capsule 100.

The housing 210 of the air valve 200 is provided with an annular concave portion 211 inside the hollow bladder 100. The annular concave portion 211 surrounds the vent hole 220. The sealing end 231 of the check valve body 230 is provided with an annular convex portion 233. The annular convex portion 233 corresponds to the annular concave portion 211, so that when the check valve body 230 closes the vent hole 220, the annular convex portion 233 of the check valve body 230 is engaged with the annular concave portion 211. The design of the annular convex portion 233 and the annular concave portion 211 can effectively enhance the sealing effect of the check valve body 230. For example, when the sealing end 231 of the check valve body 230 fails to closely fit the inside of the housing 210 of the air valve 200, so that there is a slight gap between the sealing end 231 and the housing 210, because the annular concave portion 211 and the annular convex portion The setting of 233 makes it necessary for the air to bypass the annular convex portion 233 in order to escape from the hollow capsule 100 to the vent hole 220 through the annular concave portion 211, or enter the hollow capsule 100 from the vent hole 220, which greatly increases the air escape Difficulty.

The housing 210 of the air valve 200 is provided with an openable and closable cover 212. The inner edge of the cover 212 can be provided with an airtight gasket. When the openable and closable cover 212 is closed, the vent hole 220 and the check valve body 230 can be closed in Inside the housing 210 of the gas valve 200.

As shown in FIG. 8, when the oil retaining rope 1 of the present invention is not used, each hollow capsule 100 is not filled with air and is in a flat sheet shape, and the weight 400 is not hung from the hollow capsule 100, so I can The hollow bladder 100 is easily folded and stored, so that the oil trap 1 of the present invention is convenient for storage and transportation. Conversely, if the oil skimmer 1 of the present invention is to be used, the stored oil skimmer 1 can also be easily transported to a designated location, and then be pumped up.

When inflating, the openable and closable cover 212 of the air valve 200 on the hollow bladder 100 is first opened, and then the valve port end 232 of the check valve body 230 is pressed to lower the check valve body 230 and compress the biasing element 240, thereby Open the vent 220 of the air valve 200. At this time, an external air source (not shown) can input air into the hollow bladder 100 through the vent 220. After the inflation is completed (as shown in FIG. 9), the external force applied to the check valve body 230 is released, then the biasing element 240 rebounds and biases upward, and drives the check valve body 230 to move up, making the check valve The sealed end 231 of the body 230 closes the vent hole 220, and the annular convex portion 233 on the sealed end 231 engages the annular concave portion 211 on the air valve 200 to completely seal the air valve 200 so that the air in the hollow capsule 100 cannot escape . Finally, the openable and closable cover 212 of the air valve 200 is closed to close the check valve body 230 and the vent hole 220 in the housing 210 of the air valve 200.

The oil retaining cable 1 of the present invention can be applied to various water areas, such as oceans, lakes, rivers, ponds, streams, reservoirs, and the like.
