Description

Technical Field

[0001] The present invention relates to the technical field of water surface pollution cleaning, and in particular to an oil boom deployment bag, which is mainly used for rapid emergency response to oil spill accidents. Background Art

[0002] For oil-related emergency response, oil boom deployment is the most fundamental and common equipment. During marine oil spill emergency response, booms can block the spread of floating oil on the sea surface and direct it toward relevant equipment. To improve oil spill response capabilities and minimize the impact of such incidents on the ecological environment, the ability to contain oil spills immediately after an incident is crucial. Rapid deployment booms are a specialized type of boom designed to meet this need.

[0003] Conventional oil booms are typically installed on reels and require specialized oil spill response vessels to deploy them slowly. Rapid-deployment booms, however, require no specialized vessels or reels and can be deployed quickly and easily in just one to two minutes. Currently, high-speed deployment booms, as the primary defense against oil spills, are gradually gaining market share in China. Purchases are increasing, and since the 1990s, a number of rapid-deployment boom systems have emerged.

[0004] The Canadian patent "Method for Packaging Oil Boom and Oil Boom Bag Using the Method" (Patent Application No. 2229478) describes a method for packaging and deploying oil boom. The boom is folded into a serpentine shape and placed inside a boom bag that can be opened and tightened. The boom bag is made of foldable material and has a float at the end.

[0005] This type of boom has several advantages over other booms: low resistance, allowing it to be deployed from small boats; it prevents water ingress and weight gain; it can be deployed in shallow water; and it can be deployed in various shapes. Consequently, this type of boom has a high inventory among similar equipment.

[0006] Since the structure described in this Canadian patent was first introduced, this rapid deployment boom has only undergone limited minor improvements and still faces some problems. Figure 1 、 2 As shown, the primary problem is that the boom bag 2 needs to be towed by a vessel 6, and the patent's design is incomplete at the connection between the towing strap 3 and the boom bag 2. The boom bag's side closest to the vessel is directly connected to the towing strap. When the vessel is traveling at high speed, the boom bag will sink into the water, significantly increasing drag and the risk of losing control of the boom bag's posture. Summary of the Invention

[0007] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide an oil boom deployment bag, which can significantly reduce water surface resistance when being towed by a vessel, further preventing the oil boom deployment bag from sinking, and keeping it floating with the front end tilted upward during deployment, so that the force on the oil boom deployment bag is more even when towed by the vessel, thereby reducing the possibility of breakage during deployment and further maintaining the stability of the oil boom deployment bag.

[0008] The technical solution of the present invention is as follows: the boom deployment bag is connected to the hull (1) through a towing strap (2); the front end of the main body (3) of the boom deployment bag is close to the stern; the boom (4) is folded into several sections and stored in the main body of the boom deployment bag; the front end of the boom is close to the stern and the rear end is connected to the resistance anchor (6) through an anchor rope (5);

[0009] A triangular head (7) is connected to the front end of the main body, the top angle of the triangle points to the direction of the ship's travel, the two sides of the triangle are equal and foam floats (71) are set, PVC cloth is set at the upper and lower ends of the foam float, and the head is triangular after sewing;

[0010] An upper reinforcement belt (72) and a lower reinforcement belt (73) are respectively provided on the upper and lower surfaces of the head, and both the upper reinforcement belt and the lower reinforcement belt extend to the main body and are sewn and fixed;

[0011] The lower reinforcement belts are three non-parallel reinforcement belts, the middle one is the bisector of the top angle, and the other two are respectively arranged on one side of the middle one. The three lower reinforcement belts extend out of the foam float, and the front end is provided with a fixing ring connected to the towing belt.

[0012] The oil boom deployment bag of the present invention is connected to a triangular head at the front end of the main body, and the vertex angle of the triangle points to the direction of travel of the ship, so that the water surface resistance can be greatly reduced when being towed by the ship; the foam float provided can further prevent the oil boom deployment bag from sinking, so that it remains floating during deployment and the top of the arrow is tilted upward; an upper reinforcement belt and a lower reinforcement belt are respectively provided on the upper and lower surfaces of the head, and the upper reinforcement belt and the lower reinforcement belt are both extended to the main body and sewn and fixed, connecting the triangular head and the main body as one, so that the force is uniform when the ship is towing; the lower reinforcement belt is three non-parallel reinforcement belts, the middle one is the bisector of the vertex angle, and the other two are respectively arranged on one side of the middle one, and the three lower reinforcement belts extend from the foam float, and a fixing ring connected to the towing belt is provided at the front end, so that the force is more uniform when the ship is towing, and the connection points of the towing belt are also increased, so that the possibility of breakage during deployment is reduced, and the posture of the oil boom bag during deployment is further maintained stable.

For example, a process, method, apparatus, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or equipment.

[0022] like Figure 1-5 As shown, this boom deployment bag is connected to the hull 1 via a towing strap 2. The front end of the main body 3 of the boom deployment bag is close to the stern. The boom 4 is folded into several sections and stored in the main body of the boom deployment bag. The front end of the boom is close to the stern and the rear end is connected to the resistance anchor 6 via an anchor rope 5.

[0023] A triangular head 7 is connected to the front end of the main body, with the apex of the triangle pointing in the direction of the boat's travel. The two sides of the triangle are equal and are provided with foam floats 71. PVC cloth is set at the upper and lower ends of the foam floats. After sewing, the head is triangular;

[0024] An upper reinforcement belt 72 and a lower reinforcement belt 73 are respectively provided on the upper and lower surfaces of the head, and both the upper reinforcement belt and the lower reinforcement belt extend to the main body and are sewn and fixed;

[0025] The lower reinforcement belts are three non-parallel reinforcement belts, the middle one is the bisector of the top angle, and the other two are respectively arranged on one side of the middle one. The three lower reinforcement belts extend out of the foam float, and the front end is provided with a fixing ring connected to the towing belt.

[0026] The oil boom deployment bag of the present invention is connected to a triangular head at the front end of the main body, and the vertex angle of the triangle points to the direction of travel of the ship, so that the water surface resistance can be greatly reduced when being towed by the ship; the foam float provided can further prevent the oil boom deployment bag from sinking, so that it remains floating during deployment and the top of the arrow is tilted upward; an upper reinforcement belt and a lower reinforcement belt are respectively provided on the upper and lower surfaces of the head, and the upper reinforcement belt and the lower reinforcement belt are both extended to the main body and sewn and fixed, connecting the triangular head and the main body as one, so that the force is uniform when the ship is towing; the lower reinforcement belt is three non-parallel reinforcement belts, the middle one is the bisector of the vertex angle, and the other two are respectively arranged on one side of the middle one, and the three lower reinforcement belts extend from the foam float, and a fixing ring connected to the towing belt is provided at the front end, so that the force is more uniform when the ship is towing, and the connection points of the towing belt are also increased, so that the possibility of breakage during deployment is reduced, and the posture of the oil boom bag during deployment is further maintained stable.

[0027] Preferably, there are three upper reinforcement strips, so that the head and the main body can be connected more securely.

[0028] Preferably, the upper reinforcement strips are three parallel strips, with the center strip serving as the bisector of the top angle, and the other two strips equidistantly positioned on either side of the center strip. This arrangement ensures balanced force on the boom deployment package when the vessel is traveling at high speed, thereby reducing drag.

[0029] Preferably, if Figure 4 As shown, the oil boom is composed of multiple single sections, the connection between each single section is foldable, the length of a single section is equivalent to the width of the oil boom deployment package body, and the length of the oil boom after folding is less than the length of the oil boom deployment package body.

[0030] Preferably, the vertex angle is 60°-120°. Figure 5 As shown, the vertex angle is a right angle, which can balance the manufacturing cost and structural stability. Of course, vertex angles of other angles can also be set.

[0031] Preferably, if Figure 6 、 7As shown, a lock buckle 8 is provided on the PVC cloth on the left and right sides of the rear end of the main body, and a lock ring 9 that can be extended from the lock buckle is provided on the inner side of the main body at the corresponding position. Two steel wires 10 pass through the lock ring and are connected to the anchor rope in the middle of the rear end of the main body; a Velcro 11 is provided on the side of the main body, and the anchor rope is fixed therein after the Velcro is attached. A buckle structure is provided at the rear end of the main body of the present invention, which closes the tail of the oil boom deployment bag and prevents the oil boom from automatically sliding out when it is not deployed. At the same time, after the resistance anchor is thrown into the water, the steel wire is automatically pulled out to open the buckle, which does not affect the normal deployment of the oil boom. The Velcro on the side of the present invention can fix the anchor rope connecting the oil boom and the resistance anchor inside it, avoiding the anchor rope from getting tangled and knotted when the oil boom deployment bag is towed. At the same time, the Velcro can be automatically opened by pulling force during deployment, which does not affect the normal deployment.

[0032] Preferably, if Figure 6 As shown, two lock buckles 8 are provided on the left and right PVC cloths at the rear end of the main body, and four lock rings 9 are provided on the inner side of the boom deployment bag at the corresponding positions. This ensures that the rear end of the boom deployment bag is tightly closed when not deployed.

[0033] Preferably, the head of the steel wire is provided with a rubber pad 101. The rubber pad provided at the head of the steel wire prevents the steel wire from automatically falling out, thereby ensuring that the oil boom does not fall out before reaching the deployment position.

[0034] Preferably, the main body is made of PVC cloth with holes on both sides. After the boom is folded into several sections for storage, the PVC cloth is wrapped around the boom and tied with ropes on the lower surface to form a foldable boom bag. This makes it easy to store the boom and allows for folding.

[0035] Preferably, if Figure 3 As shown, the drag anchor is made of PVC cut material, sewn into an umbrella shape. The drag anchor 6 is placed on the hull or on the head side of the boom deployment bag. The tip of the boom's umbrella shape is not closed, but has an opening. The drag anchor is connected to the rear end of the boom via an anchor line. The anchor line extends from the rear end of the boom deployment bag, is secured by Velcro on the side of the bag, and then extends toward the head, where it connects to the drag anchor.

[0036] The working principle of the present invention is as follows:

[0037] The present invention should be prepared before use. First, loosen the rope of the boom deployment bag and unfold it. Fold the boom as required and place it in the deployment bag. After connecting the anchor rope to the end of the boom, close the boom deployment bag and tighten the rope. Arrange the anchor rope, straighten it and place it in the Velcro on the side, close the Velcro to fix it, and guide it along the side to the head of the boom deployment bag. Finally, press the buckle at the rear end of the main body. Figure 6The anchor is aligned with the hook as shown and tied with a wire attached to the anchor line. The packaged unit is placed on the shore or in a storage area, either straight or folded again. The drag anchor is connected to the other end of the anchor line and set aside, ensuring that the remaining length of anchor line is properly folded or curled.

[0038] In an oil spill emergency, the boom deployment bag is connected to the stern of the vessel using a towing strap, and a drag anchor is placed on the vessel's deck. The vessel then sails out of the dock and carries the folded boom and deployment bag into the water. Thanks to its arrow-shaped foam float and triangular head design, the boom deployment bag maintains a horizontal, pointed-up position while being towed through the water. This prevents the vessel from experiencing significant drag due to the boom head sinking into the water. As the vessel moves, the boom deployment bag is towed by three reinforced straps, applying tension evenly to the front of the bag, preventing the towing strap from breaking at the connection point. A buckle at the rear end of the main body secures the rear end of the bag during towing, while a rubber pad at the end of the wire rope prevents the wire from uncoiling, ensuring the boom is secured until it reaches its deployment point. The anchor rope, secured within a Velcro strap, is protected from disturbances by currents, ensuring safe deployment.

[0039] After arriving at the operation area, the ship maintains a constant speed and the crew drops the drag anchor into the water. As the ship moves in the water, the umbrella-shaped drag anchor is subjected to the resistance of the water and begins to straighten. The stressed anchor rope will tear the Velcro from front to back, and then pull out the steel wire from the locking ring to release the lock at the tail of the deployment bag. Finally, the tension acts on the oil boom placed in the deployment bag. Under the action of the tension, the oil boom unfolds the snake-folded sections one by one and is pulled out of the deployment bag. As the ship continues to move forward, the oil boom is finally fully deployed, and the ship takes away the empty oil boom deployment bag, such as Figure 5 The process can be completed in 1-2 minutes, deploying more than 200 meters of oil boom.

[0040] After use, the boom is towed to shore by boat, cleaned and maintained, and then prepared again according to the preparation process and placed in the appropriate location. It can be quickly deployed again when it is used next time.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. It gives the head of the boom deployment bag greater buoyancy, keeping most of the boom deployment bag above the water surface during towing, reducing the resistance of the ship and speeding up the deployment speed.

[0043] 2. The connection between the boom bag and the stern is strengthened, so that the tension is applied more evenly to the boom bag, which enhances the strength and reliability of the product.

[0044] 3. It ensures that the tail end of the boom is stable before deployment, eliminating the need for manual untying of the tail end, reducing the labor of operators, lowering the difficulty of operation and enhancing the reliability of the product.

[0045] 4. It solves various problems that may occur with the anchor rope, ensures the success rate of deployment, avoids safety problems that may be caused by knots in the anchor rope, and enhances the safety of the product.

[0046] 5. It improves the towing speed, speeds up the response to emergency events, and improves work reliability.

[0047] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of protection of the technical solution of the present invention.
