JPS595476B2 - oil recovery boat - Google Patents

Description

[Detailed description of the invention] The present invention relates to an oil recovery vessel.

For example, in the event of an accident in which oil spills onto the sea from an oil tank installed in a coastal area, an oil fence is immediately erected to prevent the floating oil from spreading, an oil recovery vessel is dispatched, and the oil is Measures are taken to suction and collect floating oil within the fence, but with a conventional oil recovery vessel,
Since the oil inside the oil fence cannot be collected in one place, it is necessary to move the ship along the oil fence and bring the suction port of the oil suction pump to the oil location, which results in poor collection efficiency. There are also problems with economics.

Therefore, the present invention provides an oil recovery boat that can collect and efficiently recover oil floating on the water surface without moving the boat.

In order to achieve the above-mentioned object, the present invention includes an arm that can be raised and raised freely provided on a fixed base of a hull, a float provided at the tip of the arm, and a float disposed inside the float floating on the water surface. , a pump that sucks floating oil on the water surface through an opening provided in the float and collects it in an oil recovery tank inside the hull, and a passage formed horizontally penetrating the lower part of the fixed base of the hull. , a suction device that sucks water near the bottom of the float through the passage, and a supporter for preventing the oil fence from approaching, which is provided on the side of the hull on the entrance side of the passage.

An embodiment of the present invention will be described below with reference to the drawings.

1 is a fixed stand set up in the center of the deck of the hull 2, 3 is a swivel stand placed on the fixed stand 1, 4 is a support stand set up on the swivel stand 3, and 5 is the upper end of the support stand 4. It is an arm that extends from the top and can be lifted up and down, and is made up of three links 5a, 5b, and 5c, and a float 6 is suspended from the lower end of the tip link 5a.

Although not shown, this arm 5 includes a hydraulic cylinder,
Each link 5a is lifted up by a winch or the like.

5b and 5c are rotatable.

An oil suction pump (not shown) is disposed inside the float 6, and a pipe (not shown) extending from the pump passes through the links (5a to 5c) and the strut 4 to the hull 2. Floating oil on the water surface is sucked through an opening (not shown) provided in the float 6 and collected in the oil recovery tank inside the hull. do.

Reference numeral 7 denotes a passage formed by horizontally penetrating the lower part of the fixed base 1 of the hull 2. Reference numeral 8 denotes a fan disposed in the center of the passage 7, which blows the water in the passage 7 in the direction of the arrow. It is something that attracts attention.

9 is an abbreviated supporter extending from the side of the hull 2 on the entrance side of the passage 7, and the oil fence 10 is connected to the hull 2.
This prevents people from approaching.

11 is a storage reel for the oil fence 12 provided on the deck, and 13 is a guide fitting for the oil fence 12.

The operation of the above configuration will be explained.

First, the ship is self-propelled to the oil fence 10, which is set up on the water surface to prevent floating oil from spreading, and then the swivel platform 3
At the same time, the arm 5 is raised and lowered to float the float 6, which is placed on the deck as shown in FIG. 1, on the water surface inside the oil boom 10 as shown in FIGS. 2 and 3.

Next, the pump in the float 6 is activated and the fan 3 is activated.

Then, the floating oil on the water surface is sucked by the pump and collected into a tank within the hull 2.

If this were the only option, only the oil around the float 6 could be recovered, but according to this embodiment, since the fan 8 sucks the water in the direction of the arrow, the water in the oil fence 10 also flows toward the passage 7. As a result, the oil on the water surface also moves toward the passage 7.

Therefore, the oil gathers at the float 6 located near the entrance of the passage 70, and all the oil in the oil boom 10 can be collected without moving the float 6.

By the way, when water is sucked by the fan 8, the oil fence 10 is also pulled by it, and there is a risk that the oil fence 10 will be drawn into the passage 7. However, according to this embodiment, the side surface of the hull 2 on the population side of the passage 7 is Since the supporter 9 is provided at the bottom, the supporter 9 prevents the oil boom 10 from approaching the hull 2 abnormally, and there is no risk of it being drawn into the passage 7.

As described above, according to the oil recovery vessel of the present invention, when floating oil in an oil fence is collected by suction via a float, the floating oil is pulled by the water sucked into the passage and collects at the float. It's coming.

Therefore, all the oil in the oil boom can be recovered without moving the hull or floats, resulting in high recovery efficiency and excellent economic efficiency.

Furthermore, since a supporter for preventing the oil fence from approaching is provided, there is no fear that the oil fence will be drawn into the passage, and safety is also excellent.
