Description

An apparatus for pulling out useless net}

The present invention relates to a waste fishing net lifting device connected to the ship by a wire rope, it is installed so as to drop deep in the water, and relates to a waste fishing net lifting device to lift the waste fishing nets submerged in the water while the ship is running.

Waste fishing nets dumped at sea are causing catastrophic damage to ships sailing beyond mere marine pollution. If a closed fishing net is caught by the propeller of a sailing ship, the propulsion of the propeller may be disturbed and the vehicle may become inoperable, or the clutch, the most vulnerable part of the shaft, may be damaged, and even the main engine may be damaged.

The impact is even more severe on smaller ships than on larger ships.

Since waste fishing nets are wastes under the Marine Pollution Prevention Act and Waste Disposal Act, wastes should not be disposed of outside of a fixed place or facility provided for waste collection. In practice, however, most of the waste fishing nets are not collected and are discarded in the sea.

The biggest reason why waste fishing nets are discarded in the sea is because there are no companies or places where waste fishing nets are collected on land, or where there is no shortage of waste fishing nets. Becomes difficult ..

The clutch is the most vulnerable part of the shaft system and will be damaged first if the fishing net is caught on the propulsion shaft or if it is disturbed by the rotation of the propeller for other reasons.

The main damage to the main engine was 51.7% due to overhaul of maintenance and repair, but 13.5% of the waste fishing nets were wound up in the propeller. Only four accidents caused damage to the main engine, so the problems caused by waste fishing nets are very serious and need to be collected.

However, in the past, there have been no devices specifically designed for collecting waste fishing nets, and therefore, the collection operation of the waste fishing nets has been largely dependent on the manual operation by scuba divers. Therefore, the waste fishing nets could not be collected efficiently, and the collection cost was also very expensive, so there was a problem that the collection operation was not executed properly.

The present invention is to solve such a problem, by connecting the waste fishing net lifting device, which is formed with a catching means for collecting the waste fishing net to the ship by using a wire rope, so that the waste fishing net is dropped in the water while the ship is running, the waste fishing net Make it easy to collect during this run.

To this end, in the present invention, the waste fishing net is connected to the ship by a wire rope for a long time to be located deep in the ship, so that the floating fishing nets (floating or submerged in the water) can be easily collected,

Since the waste fishing net is provided with a plurality of catching means formed in the shape of an umbrella, once the waste fishing net is caught by the catching means of the waste fishing net, it is hardly separated, so that the waste fishing net can be effectively collected.

Referring to the present invention in detail by the accompanying drawings as follows.

1 is a schematic view showing a state of use of the lifting device according to the present invention, Figure 2 is a schematic diagram showing a state in which the lifting device according to the present invention in use (water),

The waste fishing net 1 is connected to the ship by the wire rope 2 long and is located in the depth of the ship while driving.

In the illustrated embodiment, several waste fishing nets 1 are connected to barges 4 using wire ropes 2, and the barges 4 are connected to tugs 2 so that the power of the tugboats 2 is reduced. By traveling together, the waste fishing net lifting device (1) is draped by the wire rope 2 in the opposite direction of the running direction, in this case by adjusting the length of the wire rope (2) waste fishing net lifting machine (1) ) To reach the position of the fishing net that sank to the bottom of the sea. (See Fig. 2)

In the illustrated embodiment, the structure of the waste fishing net 1 is connected to the barge 4, but the scope of the present invention is not limited thereto, and may be installed in various vessels by various methods. In addition, the present invention uses the wire rope (2) as a connecting means of the waste fishing net (1), but is not limited to the scope of the present invention, if it has sufficient tensile strength and elasticity to replace it of the same category Since it will be seen as a technology, the scope of the present invention can be naturally expanded.

Figure 3 is a front view of the lifting device according to the present invention, Figure 4 is an enlarged view showing only part A in Figure 3, Figure 5 is a bottom view showing a state viewed from the bottom portion A in Figure 3,

The closed fishing net lifting device 1 is a rope fixing part 11 for connecting the wire rope 2, a vertical frame 13 to which the rope fixing part 11 is coupled, and the vertical frame 13 at the upper end thereof. Is connected to the bottom of the consisting of the locking means 17 is formed in the shape of an umbrella.

Meanwhile, two vertical frames 13 and 13 'are connected by a horizontal frame 12 and an intermediate frame 14, or as shown in FIG. 3, three vertical frames 13 and 13' ( 13 ') may be configured to be spaced apart from each other by a predetermined interval by the horizontal frame 12 and the intermediate frame (14).

Even in this case, the catching means 17 are respectively installed at the lower ends of the vertical frames 13, 13 'and 13', and do not rotate without being rotated when the waste fishing net 1 is pulled by the wire rope 2. In order to maintain the rope fixing portion 11 is provided on each of the vertical frame 13, 13 'located at both ends.

Meanwhile, in order to maintain sufficient tensile strength and impact resistance, the reinforcing frame 15 may be installed at an angle between the horizontal frame 12 or the intermediate frame 14 and the vertical frame 13, 13 '. have.

In addition, a depth observation camera 16 may be provided so that the underwater environment can be observed during operation, and at this time, the image photographed by the depth observation camera 16 is transmitted to the monitor 6 located on the ship. It is composed.

Referring to the operation method of the present invention configured as described above are as follows.

Lung fishing nets are easy to hang on the reef (5) when described the salvage method of waste fishing nets on the reef as follows.

The tugboat 3 and the waste fishing net 1 are connected with a wire rope 2 to pull the waste fishing net 1 and the catching means 17 of the waste fishing net 1 is hooked to the seabed reef 5. If the wire rope 2 cannot proceed abnormally, the maximum tensile force acts on the wire rope 2, and when the tugboat 2 is momentarily retracted slightly, the wire rope 2 which is pulled tightly has an elastic restoring force to act in the opposite direction to the twisted state. In this case, when the wire rope 2 rotates, the catching means 17 of the waste fishing net lifter 1 are rotated together, and the catching means 17 of the waste fishing net lifting machine 1 are released from the seabed reef 5 and the catching means ( Waste fishing nets caught in 17) are easily collected.

On the other hand, since the waste fishing net 1 has a plurality of catching means 17 formed in the shape of an umbrella, once the waste fishing net is caught by the catching means 17 of the waste fishing net 1, it is hardly separated.

As described above, in the present invention, the waste fishing net lifting device 1, on which the catching means 17 for collecting the waste fishing nets is formed, is connected to the ship using the wire rope 2, and the waste fishing net lifting device 1 runs on the ship. By dropping underwater on the way, the closed fishing nets can be easily collected while the ship is running.

In other words, in the present invention, the waste fishing net 1 is connected to the ship by the wire rope 2 so as to be located deeply during the ship driving, and the floating fishing nets floating in the water or sinking to the bottom are easily collected. To lose,

Since the waste fishing net 1 has a plurality of catching means 17 formed in an umbrella shape, the waste fishing net is rarely separated once the catching net is caught by the catching means 17 of the waste fishing net 1. Make the collection effective.
