Description

Technical Field

[0001] This application relates to a ship environmental protection technology, specifically an air film oil containment device after a ship leaks oil. Background Art

[0002] Ship oil spill accidents have always been important issues in marine environmental protection and safety management. Traditional oil spill emergency treatment methods mainly rely on oil-absorbing equipment, oil booms, and dikes. However, these methods often face challenges such as the relatively fast spreading speed and wide spreading area of oil spills. Especially in large-scale oil pollution incidents, it is difficult to quickly and effectively control the oil spill. Some existing anti-oil spill technologies on the market mainly focus on hull structure improvement, oil spill adsorbents, and oil boom construction. However, these methods may have certain technical and economic limitations in actual applications. Therefore, there is an urgent need for a novel, efficient, and flexibly controllable oil spill accident emergency treatment technology. Therefore, it is necessary to provide an air film oil containment device after a ship leaks oil to solve the above problems. Content of the Utility Model

[0003] The purpose of this application is to provide an air film oil containment device and a deployment method after a ship leaks oil. By setting up an air film device and a deployment device, a closed oil containment area is formed on the water surface by the forward movement of the ship and the impact of water flow, preventing the spread of oil spills.

[0004] To achieve the above purpose, this application provides an air film oil containment device and a deployment method after a ship leaks oil, including an air film device and a deployment device; the air film device is arranged on the bow deck, a gas film ramp is fixed at the front end of the hull deck, the opening direction of the gas film ramp is the same as the bow direction, the opening of the gas film ramp has a gas film folded in the ship width direction passing through it, the front end of the gas film unfolds in front of the bow deck, and the other end of the gas film is stored on the bow deck after being stacked in an S shape.

[0005] Deployment devices are arranged on both sides of the bow deck. A balance bar is installed at the end of the deployment device. The balance bar is a floating body and is fixed on the edge of the gas film. The deployment device can pull the gas film to gradually unfold and immerse in the water under manual operation, and drive the deployer to move through a towing rope to realize the deployment of the oil containment device.

[0006] The air film device includes a gas film. The air film device is arranged on the bow deck. The rear end of the gas film is folded 8 times in the ship width direction and stacked on the bow deck; it also includes fixing holes. The fixing holes are on the left and right edges of the gas film, 100 mm from the edge, and one fixing hole is set every 5 m. Two balance bars arranged on both sides of the main hull are connected to the gas film through the fixing holes.

[0007] The overall air film device is arranged on the bow deck. The air film ramp is fixed on the bow deck, with a rectangular opening in the ship length direction, facilitating the fixation of the placement position and direction of the air film. The rear end of the air film is folded in the ship width direction and stacked in an S shape on the bow deck to reduce the occupied space. After the front end of the air film passes through the air film ramp, it is pulled by the balance bar float, and the air film unfolds to both sides of the ship to wrap the bottom of the ship.

[0008] Two hand-operated screws are installed on the side of the air film ramp. When the hand-operated screws rotate clockwise, the size of the air film ramp will be reduced. When the hand-operated screws rotate counterclockwise, the size of the air film ramp will be increased.

[0009] The deployment device consists of a deployer, a towing rope, and a float balance bar. The upper end of the towing rope is manually controlled to control the rib position of the entire deployment device outside the ship body. The lower end of the towing rope is connected to the upper end of the deployer. The overall shape of the deployer fits the outer surface of the main ship body. A slide rail with a height equal to the ship's side is provided near the ship side. A slide bar is arranged on the slide rail. The slide bar is connected to the float balance bar and can slide along the slide rail. The lower part of the deployer is immersed in water. The float balance bar floats naturally under the buoyancy force, driving the slide bar to slide upward along the slide rail. The end of the slide bar is fixed in the fixing hole. When the float balance bar floats upward, it drives the edges of the air film to unfold to both sides. Two deployment devices are arranged on both sides of the main ship body, symmetric about the midship longitudinal section and at the same rib position.

[0010] The deployment device selects and fixes the position of the appropriate fixing hole, usually the first hole at the front end of the air film. The float balance bar can float naturally when immersed in water, and it drives the slide bar to slide upward along the slide rail.

[0011] The front end of the air film selects an appropriate fixing hole and installs a soft rubber plate. The soft rubber plate is fixed between a total of four rubber joints on the left and right. The rubber joints are installed in the fixing holes. The soft rubber plate separates the stern propeller from the air film to prevent the propeller from cutting the air film.

[0012] A method for deploying an air film oil containment device after a ship leaks oil includes the following steps:

[0013] Step a: Rotate the hand-operated screw counterclockwise to open the air film ramp. Pass the front end of the air film through the rear of the air film ramp. The folded air film arranged on the ship's deck can be freely extracted. Manually extract a section of the air film and unfold it. Slide the float balance bars in the two deployment devices to the end of the slide rail and fix them in the fixing holes on both sides of the front end of the air film. Install rubber joints in the next four fixing holes. Place the deployment device in front of the main ship body and wait for it to be launched into the water.

[0014] Step b: Manually control two towing ropes on both sides of the hull. Two deploying devices are arranged on both sides of the main hull, symmetrically along the longitudinal midsection plane of the ship, and are at the same rib position during deployment. Place the deploying devices into the water. Under the action of buoyancy, the balance rod float floats upward along the slide rail, and the air film is unfolded towards both sides of the hull. Under the relative movement of the main hull during forward movement and the action of the water flow pushing the balance rod float, the balance rod float will automatically move towards the rear of the ship. The air film is naturally drawn from the air film ramp and immersed in the water and unfolded under the pulling of the deploying device, and the undeployed air film placed on the ship's deck will be naturally drawn downward;

[0015] Step c: When the deploying device moves to the rear of the ship, tighten the towing rope, rotate the hand-operated screw clockwise, clamp the air film between the hand-operated screw and the inner wall of the air film ramp, and the soft rubber plate separates the stern propeller from the air film to prevent the propeller from cutting the air film. Press the deploying device against the main hull and fix the air film. When the deploying device is pulled closer to the hull by the towing rope, it will cling to the outer surface of the main hull. Under the wrapping of the air film, a partially enclosed area is formed on the water surface to prevent the oil spill from further spreading around.

[0016] Compared with the related technology, the beneficial effects of the present invention are as follows:

[0017] This device can naturally deploy the air film under the action of water flow and the relative displacement of the hull during forward movement by using the deploying device;

[0018] The air film in this device can be freely installed, fixed and disassembled at the position of the deploying device, which is convenient for deployment and replacement;

[0019] This device can quickly complete the enclosure of the oil spill area of the hull by using the air film with low cost, and effectively prevent the spread of the oil spill by controlling the air film. Brief Description of the Drawings

Specific implementation mode

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In the present invention, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] As Figure 1 shown, it includes an air film device 2 and a deployment device 3; the air film device 2 is arranged on the bow deck 101, the front end of the hull deck 101 is fixed with an air film ramp 202, the opening direction of the air film ramp 202 is the same as the bow direction, the opening of the air film ramp 202 has an air film 201 folded in the ship width direction passing through it, the front end of the air film 201 unfolds in front of the bow deck 101, and the other end of the air film 201 is stored on the bow deck 101 after being stacked in an S shape;

[0032] Deployment devices 3 are arranged on both sides of the bow deck 101. A balance rod 303 is installed at the end of the deployment device 3. The balance rod 303 is a float and is fixed on the edge of the air film 201. The deployment device 3 can pull the air film 201 to gradually unfold and immerse in water under manual operation, and drive the deployer 301 to move through the towing rope 302 to realize the deployment of the oil containment device.

[0033] As Figure 2As shown in the figure, the air film device 2 includes an air film 201. The air film device 201 is arranged on the bow deck. The rear end of the air film 201 is folded 8 times in the ship width direction and stacked on the bow deck 101. It also includes fixing holes 203. The fixing holes 203 are located at the left and right edges of the air film 201, 100 mm away from the edge, and one fixing hole 203 is set every 5 m. Two balance rods 303 arranged on both sides of the main hull 1 are connected to the air film 202 through the fixing holes 203.

[0034] As Figure 3 shown in the figure, the air film device 2 is arranged on the bow deck as a whole. The air film ramp 202 is fixed on the bow deck. The opening is rectangular, and the opening direction is the ship length direction, which is convenient for fixing the placement position and direction of the air film 201. The rear end of the air film 201 is folded in the ship width direction and stacked in an S shape on the bow deck to reduce the occupied space. After the front end 204 of the air film passes through the air film ramp 202, it is pulled by the balance rod float 303, and the air film 201 unfolds to both sides of the ship and wraps the bottom of the ship.

[0035] As Figure 4 shown in the figure, two hand-operated screws 205 are installed on the side of the air film ramp 202. When the hand-operated screw 205 rotates clockwise, the ramp size of the air film ramp 202 will be reduced. When the hand-operated screw 205 rotates counterclockwise, the ramp size of the air film ramp 202 will be increased.

[0036] As Figure 5 shown in the figure, the deployment device 3 is composed of a deployer 301, a towing rope 302, and a float balance rod 303. The upper end of the towing rope 302 is manually controlled to control the rib position of the entire deployment device outside the ship body. The lower end of the towing rope 302 is connected to the upper end of the deployer 301. The overall shape of the deployer 301 fits the outer surface of the main hull 1. A slide rail 305 with the same height as the ship's side is set near the ship side. A slide bar 304 is set on the slide rail 305. The slide bar 304 is connected to the float balance rod 303 and can slide along the slide rail 305. The lower part of the deployer 301 is immersed in water. The float balance rod 303 floats naturally under the buoyancy force, driving the slide bar 304 to slide upward along the slide rail 305. The end of the slide bar 304 is fixed in the fixing hole 203. When the float balance rod 303 floats upward, it drives the edges of the air film 201 to unfold to both sides. Two deployment devices 3 are arranged on both sides of the main hull 1 respectively, symmetrically along the midship longitudinal section and at the same rib position.

[0037] As Figure 6 shown in the figure, the deployment device 3 selects and fixes the position of the appropriate fixing hole 203. Usually, the first hole at the front end 204 of the air film is selected. The float balance rod 303 can float naturally when immersed in water, and the float balance rod 303 drives the slide bar 304 to slide upward along the slide rail 305.

[0038] As Figure 7As shown in the figure, at the front end 204 of the air film, appropriate fixing holes 203 are selected, and a soft rubber plate 206 is installed. The soft rubber plate 206 is fixed between a total of four rubber joints 207 on the left and right. The rubber joints 207 are installed in the fixing holes 203. The soft rubber plate 206 separates the stern propeller from the air film 201 to prevent the propeller from cutting the air film 201.

[0039] A method for deploying an air film oil containment device after a ship leaks oil is as Figures 1-7 shown, and it includes the following steps:

[0040] Step a: Rotate the hand-cranked screw 205 counterclockwise to open the air film ramp 202. Pass the front end 204 of the air film through the rear of the air film ramp 202. The folded air film 201 arranged on the hull deck can be freely drawn out. Manually draw out a section of the air film 201 and unfold it. Slide the balance rod floats 303 in the two deployment devices 3 to the ends of the slide rails 305 and fix them in the fixing holes 203 on both sides of the front end 204 of the air film respectively. Install the rubber joints 207 in the next four fixing holes 203. Place the deployment device 3 in front of the main hull 1 and wait for launching.

[0041] Step b: Manually control two towing ropes 302 on both sides of the hull respectively. Two deployment devices 3 are arranged on both sides of the main hull 1, symmetrically along the midship longitudinal section, and are at the same rib position during deployment. Place the deployment device 3 in the water. Under the action of buoyancy, the balance rod floats 303 float upward along the slide rails 305, unfolding the front end 204 of the air film to both sides of the hull. Under the relative movement when the main hull 1 moves forward and the action of the water flow pushing the balance rod floats 303, the balance rod floats 303 will automatically move backward. The air film 201 is naturally drawn out from the air film ramp 202 and immersed in the water and unfolds under the pulling of the deployment device 3. The undeployed air film 201 placed on the hull deck 101 will be naturally drawn downward.

[0042] Step c: When the deployment device moves to the stern, tighten the towing rope 302, rotate the hand-cranked screw 205 clockwise, clamp the air film 201 between the hand-cranked screw 205 and the inner wall of the air film ramp 202. The soft rubber plate 206 separates the stern propeller from the air film 201 to prevent the propeller from cutting the air film 201. Press the deployment device 3 against the main hull 1 and fix the air film 201. When the deployment device 3 is pulled closer to the hull by the towing rope 302, it will press against the outer surface of the main hull. Under the wrapping of the air film 201, a partially enclosed area is formed on the water surface to prevent the oil spill from further spreading around.

[0043] The gas film oil containment device proposed in this application fully considers the complexity and variability of the oil spill site. By arranging the gas film device on the bow deck and combining with the design of the deployment device, it realizes the rapid and accurate enclosure of the oil spill area. The adoption of the gas film device forms a closed gas film area on the water surface, effectively isolating the oil spill and slowing down the spreading speed of the oil spill. The setting of the deployment device ensures the controllability and adaptability of the operation, making the oil spill treatment more flexible and efficient. The new ship oil spill emergency treatment device under this technical background provides an innovative solution for marine oil pollution prevention and control, with good practicability and application prospects.
