Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a method of curing and cleaning a seaweed cultivation net (hereinafter referred to as a seaweed net) after harvesting seaweed with a cleaning solution (usually seawater added with a chemical). The present invention relates to a cleaning device that is installed and used on a small ship at sea.

<Prior art> Seaweed cultivation is carried out by installing pipes 1 arranged in parallel in the longitudinal direction, as shown in Figs.
A blind-shaped net shelf connected with two vertical book strings (total length: 35cm)
~46 m) 3, usually four pieces of seaweed net (on which seaweed seeds are attached) 5 are set, and the net shelf 3 is connected to a lock 7 at the lower end and a float 8 at the upper end, and is arranged in a pocket. The seaweed net 5 is floated horizontally in the sea by tying the first and second connection strings 3a and 3b of the net rack to the first and second stop ropes 9 and 10 of the net.
Note that 6 in the figure is a cylindrical float for more reliably maintaining the horizontal state of the seaweed net.

After a predetermined period of time has elapsed, when the seaweed buds from the seaweed seeds have grown to about 25 to 30 cm, the seaweed is harvested (the seaweed buds are left behind). After the seaweed is harvested, the seaweed net has foreign substances such as green leaves and shellfish attached to it, as well as other miscellaneous bacteria, so it must be physically removed and chemically sterilized. It is necessary to keep it. That is, it is necessary to cure and wash the seaweed net. Curing cleaning was carried out by stepping on a seaweed net set on a net shelf that had been removed from a stop rope and immersed it in a cleaning tank installed on a small ship at sea that stored cleaning liquid.

Once the net racks have been cured and cleaned, they are returned to the sea, and after waiting for the seaweed buds to grow to a height of 25 to 30 cm, the seaweed is harvested again.

<Problem to be solved by the invention> However, the curing and cleaning of the seaweed nets described above is mainly carried out at sea during the winter season (November to March), and by hand (stepping).
The cleaning process was not only hard work but also not very efficient.

Furthermore, the net shelf is pulled onto the hull, and
The work of returning the ship to the sea surface was carried out manually by moving to one side of the ship, which could easily cause the ship to lose its balance, so caution was required.

An object of the present invention is to provide a laver net curing cleaning device that can solve the above problems.

<Means for Solving the Problems> The cleaning device for curing seaweed nets, etc. of the present invention solves the above problems by the following configuration.

This is a cleaning device that is installed on a small ship at sea when curing and cleaning seaweed nets, etc. with a cleaning solution.Essentially, the axis of the ship and the plane axis are approximately aligned in the cleaning tank. a washing machine having a freely rotating washing drum installed therein; a freely rotating waste rope roll installed outside the washing machine in parallel with the axis of the ship; and the washing drum and waste rope roll. a driving means connected to and driven by the roll; transmission means capable of intermittent connection between the washing drum and the waste rope roll and the driving means so that the driving rotational directions are opposite to each other; is mediated.

<Example> The present invention will be explained in detail based on an example. In the diagrams, the same reference numerals are given to the previously described parts, and all or part of the explanation thereof will be omitted.

A. The cleaning device essentially consists of the following (1) cleaning tank 11.
, (2) a waste rope roll 21 , and (3) a driving means 31 .

(1) The cleaning machine 11 has a freely rotating cleaning drum 14 disposed in a cleaning tank 12 so that the axis of the ship S and the axis of the plane substantially coincide with each other. Specifically, as shown in FIG.
It has an inverted trapezoidal cross section and is usually molded from reinforced plastic (FRP), which is used for bathtubs and the like. Further, a bearing member 20 is formed at the upper end of the central portion of both side walls of the cleaning tank 12, and both ends of the rotating shaft 15 of the cleaning drum 14 are rotatably supported by the bearing member 20. and,
In the cleaning drum 14, a plurality of (three in the illustrated example) hexagonal plates 17 are disposed between disks 16 at both ends, with their axes aligned at predetermined intervals, and further, at each vertex of the hexagonal plates 17, , is an open type in the middle with a vertical bar 18 arranged thereon. From the standpoint of winding up the net shelf, a hexagonal plate is preferable, but it may also be formed by arranging vertical bars on a circular plate, or a net body may be arranged between the vertical bars.

(2) The waste rope roll 21 is installed parallel to the axis of the hull S at a position outside the washing machine 11. Specifically, it is rotatably supported by a pair of bearing members 15.

(3) The driving means 31 is intermittently connected to the drum 14 and the roll 21 in order to drive the washing drum 14 and the waste rope roll 21. In the illustrated example, the output shaft 33 of the motor (engine) 32 and the input shaft 36 of the three-way reducer 35 are belt-transmitted, and the first and second output shafts 3 of the three-way reducer 35
7 and 38 are adapted to be belt-transmitted to the rotating shafts of the drum 14 and the roll 21, respectively, and serve as first and second transmission means G1 and G2, respectively. At this time, the driving rotation directions of the cleaning drum 14 and the waste rope roll 21 are opposite to each other (see arrows in FIG. 2). Further, first and second tension rollers 39 and 40 are arranged in the first and second transmission means G1 and G2, so that the transmission can be interrupted or interrupted by adjusting the tension.
The clutch is now operable.

In addition, all the transmission means in the above are belt transmission, but it is of course possible to use chain transmission, gear transmission, or the like.

B Next, the usage mode of the cleaning device of the present invention will be explained.

The apparatus of the above embodiment is arranged so that the axis of the cleaning machine 11 substantially coincides with the planar axis of the ship body S.
Place it on top. Then, seawater is pumped into the cleaning tank 12 and a predetermined chemical is added thereto to prepare a cleaning liquid. The amount of this cleaning liquid is such that about 1/3 of the bottom of the drum 14 is submerged. Further, a waste rope 23 that is 4 to 5 m longer than the net shelf 3 is wound around the waste rope roll 21. Note that the normal engine 32 is used in combination with one for the hull and is always in operation, and a three-way speed reducer 35 is driven via belt transmission.

(1) First, remove the first connection string 3a at one end of the net shelf 3 from the first stop rope 9, and
At the same time, the first retaining rope 9 is passed under the hull, and the let-out end of the waste rope 23 is connected to the first retaining rope 9 on the side opposite to the side where the cleaning drum 14 is connected.
Connect to.

(2) Next, the belt is pressed down by the first tension roller 39 to transmit the rotation of the first output shaft 37 of the three-way reducer 35 to the rotating shaft 15 of the cleaning drum 14. That is, the first transmission means G1 is brought into the connected state. Then, the net shelf 3 is connected to the cleaning drum 1.
It is wound up in 4. At this time, since the other end of the net shelf 3 is tied to the second stop rope 10 via the second connection string 3b, the hull S moves relatively toward the second stop rope 10 (see Fig. 2). ) At the same time, the discarded rope 23 also has its let-out end to the first stop rope 9.
It is rolled out because it is tied to.

(3) When the winding of the net shelf 3 by the cleaning drum 14 is completed, the first transmission means G1 is disconnected, the second stop rope 10 and the second connecting string 3b of the net shelf 3 are untied, and the second connection is made. The string 3b is tied to the vertical frame 18 of the drum 14 so that the net shelf 14 does not come off the washing drum 14.

(4) In this state, the first transmission means G1 is connected again, the cleaning drum 14 is rotated, and the seaweed net 5 is cleaned and cured. Usually, the drum rotation speed is 20 to 30 rpm, and the cleaning time is about 10 minutes. At this time, the seaweed net 5 is physically cleaned by the cleaning liquid by the stirring action, and the cleaning liquid is scraped up while the seaweed net 5 is washed.
penetrate inside.

(5) When the cleaning is completed, the first transmission means G1 on the side of the cleaning drum 14 is turned off, and the second connecting string 3b of the net shelf 3 is tied to the second stop rope 10. Then, the belt is pressed down by the second tension roller 40, and the rotation of the second output shaft 38 of the three-way speed reducer 35 is discarded and the rotation is transmitted to the rotating shaft 22 of the rope roll 21. That is, the second transmission means G2 is connected, and the waste rope roll 21 is driven. Then, the waste rope 23 is caught in the roll 21, and the hull S
moves to the second rope 10 side (second
direction of the white arrow in the figure). At the same time, the net shelf 3 is
It is fed out from the cleaning drum 14 to the sea surface. When the feeding of the net rack 3 is completed, the second transmission means G
2 is cut off, the tie between the waste rope 23 and the first stop rope 9 is released, and the first stop rope 9, which has gone under the hull, is tied to the second connection string 3b of the net shelf 3.

Repeat the above steps to sequentially roll up and clean other net shelves.

<Operations and Effects of the Invention> As described above, the cleaning device for curing seaweed nets, etc. of the present invention has a freely rotating cleaning drum disposed in the cleaning tank with the axis of the ship substantially aligned with the plane axis. a washing machine, a freely rotating disposable rope roll installed outside the washing machine parallel to the axis of the ship, and a washing drum and a waste rope roll connected to each other,
and a driving means to be driven, and between the washing drum and the waste rope roll and the driving means,
This configuration is characterized in that transmission means that can be switched on and off are interposed so that the drive rotation directions are opposite to each other, so that the following operations and effects are achieved.

(1) By rotating the cleaning drum with the net rack wrapped around it, the cleaning liquid at the bottom of the cleaning tank physically cleans the cleaning liquid, and the cleaning liquid permeates into the seaweed net while being scraped up. Therefore, compared to the conventional foot-operated method, not only is it free from heavy labor, the cleaning efficiency is also good, and less cleaning liquid is required.

(2) When winding the net shelf into the washing drum, tie one end of the net shelf to the washing drum and fix the other end to a rope in the sea, and at the same time,
The feeding end of the waste rope is fixed to the other stop rope and fed out into the sea, and conversely, the net shelf is fed out by winding up the waste rope and moving the ship relatively in the feeding direction, so the ship's hull The net racks are also stable, and lifting the net rack onto the ship and rolling it out to the sea surface is easy and does not require much attention.

The device of the present invention is currently applicable only to seaweed nets, but in the future it may be applicable to curing and cleaning other seaweed or shellfish aquaculture nets through design modifications by those skilled in the art. It is possible that
Therefore, the technical scope of the present invention also extends to cases where it is applied to cleaning other aquaculture nets.
