Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support device for a fishing net cleaning machine that cleans fishing nets.

[Conventional technology]

For example, fishing nets such as ikesu nets at fishing farms are set up hanging in the sea, and shellfish, seaweed, etc. adhere to these fishing nets. It is necessary to remove shellfish and seaweed attached to these fishing nets, but in this case, divers dive into the sea with fishing net cleaning machines and high-pressure water jet devices.
Fishing nets are cleaned by rotating the brushes of this fishing net cleaning machine or by jetting high-pressure water. Depending on the condition of the fishing net, instead of cleaning it, the entire fishing net may be replaced, resulting in a great deal of waste.

[The problem that the idea attempts to solve]

However, fishing nets like the Ikesu nets at fishing farms,
Because they are partially suspended in the sea, fishing nets often sway when subjected to the forces of ocean currents and waves, making them easier to move. Under such conditions, when a diver cleans a fishing net with a fishing net cleaning machine, he must support the fishing net cleaning machine and hold it in the correct posture, and move the fishing net cleaning machine while working while following the movement of the fishing net. The work is difficult and requires high-paid divers, making the work expensive.

It is desirable from the viewpoint of facilitating the work and saving labor that the cleaning work of moving the fishing net cleaning machine while maintaining it in the correct posture should be carried out by an appropriate device having suitable moving means and supporting means, rather than using a diver. .

Therefore, for example, it is conceivable to suspend the fishing net cleaning machine in the sea using a wire wound around a winch and move the fishing net cleaning machine to perform the cleaning work without using a diver. When cleaning fishing nets with a fishing net cleaning machine suspended from a wire, it is necessary to move the fishing net cleaning machine vertically and horizontally and check the vertical and horizontal cleaning positions of the fishing net in place of the diver. There is. The fishing net can be moved in the vertical direction by letting out an appropriate amount of wire, but by simply letting it out, it is difficult to set the amount of wire to be let out, and it is difficult to determine the cleaning position in the vertical direction on the fishing net.

In addition, in order to move the fishing net cleaning machine horizontally, it is sufficient to move the wire itself horizontally along the surface of the fishing net, but even if you try to move the wire horizontally, it will not hang on the wire due to the force of ocean currents and waves. The lowered fishing net cleaner may be washed away, making it difficult to determine the horizontal reference position on the fishing net, and therefore making it impossible to determine the amount of horizontal movement.

Regarding the fishing net cleaning device, for example, Japanese Patent Application Laid-open No. 1-108929, Japanese Utility Model Application No. 55-139671,
One disclosed in Japanese Patent Application Laid-Open No. 62-201530 is known.

However, Japanese Unexamined Patent Application Publication No. 108929/1989,
The structure disclosed in Publication No. 139671 and Japanese Patent Application Laid-open No. 1986-201530 has a structure in which the fishing net cleaning machine is moved up and down in the sea along a guide rail, and the structure is complicated and there are fitting and sliding parts in the sea. This can cause malfunctions and require frequent maintenance and inspection.

Also, Japanese Patent Application Laid-open No. 1-108929,
The device disclosed in Japanese Patent No. 139671 requires a guide rail as a support member for the case, making the structure of the entire case complicated.

The present invention was made to solve the above-mentioned problems, and its purpose is to provide a support device for a fishing net cleaning machine that can suspend the fishing net cleaning machine without changing the structure of the fishing net. be.

[Means to solve the problem]

It has a guided portion consisting of a T-shaped bar 27, and this T-shaped bar 27 is connected to the tip of the wire 14 wound around the winch 12 on the work boat 1.

Next, the operation of the present invention will be explained.

First, the work boat 1 carrying equipment such as the swing arm 10 and the fishing net cleaning machine 15 is sailed near the aquaculture cage, and then the work boat 1 is fixed at a predetermined position of the culture cage using the hook arm 4. After lowering the fishing net cleaner 15 suspended from the swing arm 10 into the sea, the swing arm 10 is supported on the slide rail 8. Thereafter, the swing arm 10 is positioned at an arbitrary position on the slide rail 8, and the fishing net cleaner 15 is set in the raised position (indicated by the solid line) as shown in FIG. The upper side is put into the guide groove 13A of the guide part 13 and fixed. Based on this state, the fishing net 7 is cleaned while the fishing net cleaning machine 15 suspended from the wire 14 is lowered by gravity by operating the winch 12. The details are explained below.

That is, as shown in FIGS. 1 and 4, the work boat 1
The upper winch 12 is operated to let out the wire 14 to move the fishing net cleaner 15 downward, and at the same time, the hydraulic motor 19 is operated to rotate the propeller 20 and the brush 23. The rotation of the propeller 23 causes seawater to flow through the water passage 21 in the case 18 in the direction of arrow X, generating a thrust that moves the fishing net cleaner 15 itself in the direction of the fishing net 7, and the brush 23 comes into contact with the fishing net 7. At the same time, each guide wheel 17 connects to the fishing net 7.
The needle bar 26 enters the mesh of the fishing net 7.

When moving the cleaning machine main body 16 suspended by the wire 14, each needle bar 2 of each guide ring 17
Each guide wheel 17 rolls on the fishing net 7 while the fish 6 enters the mesh of the fishing net 7. At that time, the cleaning machine main body 16
Even if the needle bar 26 of each guide ring 17 tries to meander,
is caught in the mesh of the fishing net 7, and each guide wheel 17 rolls on the fishing net 7 while being guided by the mesh of the fishing net 7. In this way, while the fishing net cleaner 15 is moved over the fishing net 7, seaweed and the like attached to the fishing net 7 are removed by the rotation of the brush 23.

When the fishing net cleaner 15 falls by gravity by a predetermined distance, it becomes in the state shown by the dotted line in FIG. Therefore, it rises.

The rising fishing net cleaner 15 stops at a position where its T-shaped bar 27 contacts the guide groove 13A of the swing arm 10, and the T-shaped bar of the fishing net cleaner 15 touches the guide groove 13A of the swing arm 10. is locked.

Next, when the swing arm 10 is released from its position and rotated by a predetermined angle in the direction of arrow Y (shown in FIG. The swing arm 10 is then taken out and ready to move the swing arm 10 horizontally.

When the swing arm 10 is horizontally moved by the width of the brush 23 on the slide rail 8 via the saddle 9, the fishing net cleaning machine is locked to the swing arm 10 and is thus fixed to the swing arm 10. 15 also moves along the surface of the fishing net 7 by the width of the brush 23.

In this state, the swing arm 10 is positioned on the slide rail 8 of the work boat 1, and then the swing arm 10 is rotated in the direction opposite to the direction of arrow Y to bring the brush 23 of the fishing net cleaner 15 into contact with the fishing net 7. Thereafter, the fishing net 7 is cleaned during the lowering operation of the fishing net cleaner 15 as described above.

The fishing net 7 is completely cleaned by repeating the lowering, raising and horizontal movement of the fishing net cleaner 15 in sequence. The movement path of this fishing net cleaner 15 is shown as a dotted line in FIG.

According to the above configuration, when cleaning the fishing net 7 suspended in the sea, the cleaning can be performed without using a diver by using the fishing net cleaning machine 15 suspended by the wire 14. When using the fishing net cleaning machine 15, the fishing net cleaning machine 15 can be lowered vertically based on the guide groove 13A of the swing arm 10, so that the amount of wire 14 fed out from the swing arm 10 is 15 descent amounts can be set and the vertical position can be determined.

In addition, when the T-shaped bar 27 of the fishing net cleaning machine 15 is locked in the guide groove 13A of the swing arm 10, the fishing net cleaning machine 15 is fixed to the swing arm 10, and its horizontal position is fixed and easy to move horizontally. Therefore, the fishing net cleaner 15 can be moved a predetermined distance horizontally along the surface of the fishing net 7 based on this position.

As described above, when the fishing net cleaner 15 is suspended by the wire 14 and the underwater fishing net 7 is cleaned without a diver, the vertical and horizontal positions of the fishing net cleaner 15 on the fishing net 7 are determined by the diver. Therefore, the entire surface of the fishing net 7 can be reliably cleaned while checking this position.

Furthermore, according to this embodiment, since the support member consisting of the hook arm 3 is provided on the side 2 of the work boat 1, which is a structure separate from the Ikes, it is not necessary to provide a rail for guiding the support member on the Ikes frame 2. Without,
The structure of the ice cube becomes simpler.

In this embodiment, the work boat 1 is used as an example of the structure, but the structure is not limited to this, and may be a concrete structure built along the coast, for example.

In addition, in this embodiment, the swing arm 1
A guide portion 13 having a guide groove 13A is formed at the tip of the fishing net cleaner 15, and the T-shaped bar 27 of the fishing net cleaner 15 is engaged with the guide groove 13A, thereby fixing the fishing net cleaner. However, in order to keep the fishing net cleaner 15 in a fixed state, the structure is not limited to this combination. It is also possible to form a combination structure in which a T-shaped bar of the swing arm 10 is engaged with a guide groove of the fishing net cleaner 15.

Further, in this embodiment, the fishing net 7 is cleaned while the fishing net cleaning machine 15 is lowered, but the fishing net 7 can also be cleaned while the fishing net cleaning machine 15 is raised.

In this embodiment, the fishing net cleaning machine 15
Although the case where the fishing net 7 suspended in the sea is cleaned has been described above, the present invention can also be applied to a fishing net suspended in a lake or a river.

[Effect of idea]

As described above, according to the support device for a fishing net cleaning machine according to the present invention, it is sufficient to provide a support member in a structure separate from the Ikesu and to simply suspend the fishing net cleaning machine from the support member with a wire. The structure of the support member of the fishing net cleaning machine is simplified, and there is no need to provide a rail for guiding the support member to the cage frame as in the past, and the structure of the fish net cleaning machine is simplified.

In addition, since a guide part is provided at the tip of the support member, when moving the fishnet cleaner horizontally, the guided part of the fishnet cleaner is locked to the guide part and the fishnet cleaner is fixed to the support member. After that, by rotating the support member, the fishing net cleaner can be reliably moved away from the fishing net.
