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 using a sash-like net shelf (full length 35-45m) 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. Second stop rope9.
10, the first and second connecting strings 3a and 3b of the net shelf are tied together, and the seaweed net 5 is suspended horizontally in the sea. The middle 6 on the garden side is a cylindrical float, which is used to more reliably maintain the horizontal state of the seaweed net.

In this way, after a predetermined period of time, when the seaweed buds from the seaweed seeds have grown to about 25 to 30 cm, the seaweed is cut off (the seaweed buds are left behind). Since foreign substances such as green spores and shellfish are attached, as well as other miscellaneous fungi, it is necessary to physically remove them and chemically sterilize them. That is,
It is necessary to cure and clean the seaweed net. Curing cleaning is carried out in a cleaning tank installed on a small ship at sea, where cleaning liquid is stored.
The seaweed net set on a net rack that had been removed from the stop rope was dipped in the seaweed net, and the process was carried out by stepping on it.

In this way, the net racks that have been cured and washed are returned to the sea, and the seaweed buds are allowed to grow to a height of 25 to 30 cm.
Harvest seaweed.

<Problem to be solved by the invention> However, the above-mentioned cleaning and curing of seaweed nets is mainly carried out during the winter season (November 1999).
-March) to be carried out at sea and by hand (stepping).
In addition to being hard work, the cleaning efficiency was not necessarily good.

Furthermore, the work of lifting the net rack onto the ship's hull and returning it to the sea surface was done manually by moving to one side of the ship, which made the ship's balance easy to lose, requiring special care.

An object of the present invention is to provide a cleaning device for curing seaweed nets that can solve the above-mentioned problems.Means for solving the problems〉 The cleaning device for curing seaweed nets, etc. of the present invention solves the above-mentioned problems. The following configuration solves this problem.

This is a cleaning device that is installed on a small ship at sea when curing and cleaning seaweed lI4, 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 T-shelf rope roll installed parallel to the axis of the hull at an outside position of the washing machine, and a washing drum and a disposable rope. a drive means connected to and driven by the rope roll, and the drive means can be intermittent between the washing drum, the waste rope roll, and the drive means so that the driving rotation directions are opposite to each other. It is characterized in that a transmission means is interposed.

<Example> The present invention will be explained in detail based on an example. The parts of the government bond that have already been described will be designated by the same reference numerals, and all or part of their explanation will be omitted.

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

(1) The cleaning machine 11 has a freely rotating cleaning drum 14 installed in the cleaning tank 12 with the axis of the hull S substantially aligned with the plane axis. Specifically, as shown in FIG. 3, the cleaning tank 12 has an inverted trapezoidal cross section, and its bottom is usually made of reinforced plastic (FRP) used for bathtubs and the like. Further, a bearing member 20 is formed at the upper end of the central portion of both end 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. 14, a plurality of hexagonal plates 17 (three in the case of government bonds) are placed between the disks 16 at both ends, with their axes aligned at predetermined intervals, and each vertex of the hexagonal plates ! It is an open type in the middle with a crosspiece 18. From the viewpoint of winding the 114 shelf, a hexagonal plate is preferable, but it may also be formed by arranging vertical crosspieces on a circular plate, or a net body is arranged between the vertical crosspieces. You can.

(2) The waste rope roll 21 is installed parallel to the axis of the hull S at a position outside the washer 11.

Specifically, it is rotatably supported by a pair of bearing members 15.

(3) The driving means 3I is intermittently connected to the drum 14 and the roll 21 for moving 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-driven, and the first and second output shafts 37 and 38 of the three-way reducer 35 are The rotating shafts of the drum 14 and the roll 21 are transmitted by belts, and are referred to as first and second transmission means Gl and G2, respectively. At this time, cleaning drum 1
4 and the waste rope roll 21 are opposite to each other (see arrows in Figure 2). Two tension rollers 39 and 40 are arranged so that transmission can be interrupted or interrupted by tension adjustment, that is, clutch operation is possible.

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

81 Next, the manner of use of the cleaning device of the present invention will be explained.

The apparatus of the above embodiment is arranged such that the axis of the cleaning machine 11 is approximately S of the ship body.
It is installed on the hull S so as to be approximately aligned with the plane axis of the ship. 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 the bottom third of the drum 14 is submerged. In addition, a waste rope 23 that is 4 to 5 meters longer than the net shelf 3 is wound around the waste rope roll 21. Note that the engine 32 is normally operated together with the one for the ship's hull, and is driven by a belt transmission. A three-way reduction gear 35 is driven via the.

(1) First, remove the first connecting string 3a at one end of the net shelf 3 from the first stopper rope 9, connect it to the connected string 14a at the center of the cleaning drum 14, and connect the first stopper rope 9 under the hull. on the side opposite to the coupling side of the cleaning drum 14.
The let-out end of the sacrificial rope 23 is tied to the second stop rope 9.

(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 wound around the cleaning drum 14. 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 sacrificial rope 23 is also let out because its let-out end is tied to the second stop rope 9.

(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 and the cleaning drum 14 is rotated to perform curing cleaning of the seaweed net 5. Normally, the drum rotation speed is 20 to 30 rpm.
The cleaning time is approximately 10 minutes. At this time, the seaweed net 5 is physically cleaned by the cleaning liquid by the stirring action, and the cleaning liquid permeates into the seaweed net 5 while being scraped up.

(5) When the cleaning is completed, the first transmission means G1 of the cleaning drum 14 is turned off, and the second connection 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 reducer 35 is discarded and the rotation is transmitted to the rotation 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 toward the second stop rope 1o (see the arrow in Figure 2). At the same time, the rope net shelf C is let out from the washing drum 14 to the sea surface. It will be done. When the feeding of the net shelf 3 is completed, the second transmission means G2 is turned off, and the waste rope 23 and the second transmission means are disconnected.
The knot with the 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 in parallel with the axis of the ship's hull, and a driving means connected to and driven by the washing drum and the waste rope roll, 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 drum, and as the cleaning liquid is scraped up, the net is filled with 8Il! Transparent. 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) To wrap 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 stop rope in the sea. At the same time, at the same time, connect the feeding end of the waste rope to the other stop rope. The net rack is fixed and rolled out into the sea, and conversely, the net rack is rolled out by winding up a waste rope and moving the ship relatively in the direction of the unwinding, so the hull is stable and the net rack can be rolled out onto the ship. Raising it and bringing it out to sea 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 with design modifications by those skilled in the art. It is possible that

Therefore, the technical scope of the present invention extends beyond other areas! ! This also applies to cases where it is used for cleaning fishing nets.
