Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a drying device for drying out seaweed nets for cultivating seaweed and float ropes that connect the nets.

(Prior art) Originally, seaweed was dried according to the tide or in the sun.
It is their natural habitat to grow on rocky shores while submerged in the sea, but in order to take advantage of this natural ecology, we erected a pole in shallow water and spread seaweed nets along the water surface. The well-known technique of cultivating seaweed using seaweed nets is a traditional technique that has been practiced for a long time. However, in recent years, there have been fewer shallow waters in the sea, and in order to meet the increasing demand for seaweed, floating type O9
! Although there are advances in cultivation technology, the reality is that no equipment has been developed that is particularly practical as a drying device.

Therefore, it is rare that seaweed is cultivated in accordance with its natural habitat.For example, in the offshore floating method of seaweed cultivation, it cannot be dried in the sun and is contaminated with impurities such as silica algae. In order to prevent this, as a means of removing impurities such as silica algae, float ropes are removed from the seaweed net floating on the sea surface. The hard labor of removing one piece at a time, periodically immersing it in a paddle in a chemical solution mixed with acidic chemicals to kill any silica algae, etc., and then reattaching it to the original float rope is a difficult task during winter seas. The situation is that it is being carried out. Naturally, this chemical solution has negative effects on other fisheries, and for this reason, the use of this chemical solution is prohibited in many regions, and seaweed products to which such a chemical solution has been added are no longer on the table. If this occurs, it may reduce the commercial value of seaweed as a natural food, which is by no means harmless to those who eat it.

To solve this problem, use seaweed! During the J-breeding period, especially during the growing season, drying out under the sun can be carried out at any time.
This is an indispensable condition for preventing the generation of impurities such as silica algae and achieving clean growth of seaweed. Its appearance was awaited.

(Object of the Invention) This invention is an object of the present invention, in which a large number of seaweed nets stretched on the sea surface can be lifted up into the air from the sea surface or submerged in the sea, thereby increasing the number of seaweed nets during the growing period. This was done with the aim of realizing a drying equipment fk that can perform drying operations.

(Structure of the invention) This invention has the following structure as a structure for achieving the above object.
A frame assembled from long materials such as metal, a float device attached to the frame to allow the claim to float easily in water, and a pressure regulator to adjust the supply and discharge of air and water within the float device. It is characterized by having the following.

(Function) The capacity of this invention is to submerge a seaweed net drying device in the sea near the seaweed net that is floating on the sea surface, and to connect the rope t tied to both ends of the seaweed net drying device to the number that can be lifted up. The seaweed net can be tied to both sides of the net, but it can be installed in place by passing it through the guide ring of the idrobe from the underwater side and pulling it from the sea to the nori net. When the seaweed net drying device is connected to the onboard compressor and air is supplied to the tank device, the seaweed net drying device floats and pushes the seaweed net and the float rope for floating it from the sea surface into the air. Fry. By installing several seaweed net drying devices at regular intervals, it is possible to easily lift a plurality of seaweed nets from the sea surface.

This seaweed net drying device has a T-structure with two long frames (pipes) arranged in parallel.
In the center between the seaweed nets, install as many Pokuru as necessary for the number of nets to push up the float ropes that connect the seaweed nets, and attach rod pipes corresponding to the number of nets to these, and also adjust the length of the structure. A frame with a pair of two tanks attached to the float device pipes is attached at a right angle to a fixed position on a length frame (pipe), and a pair of tanks are attached to both ends of this seven-frame frame. When installing two pairs of tanks, install them at equal positions on the left and right sides of the structure 7V-m, connect each pair of tanks to both sides of the tank with a hose made of rubber, etc. Connect the tank to the air and water O supply/discharge 't-adjusting pressure regulator with a hose made of rubber, etc., and connect the pressure regulator connected to the two tanks and the pressure regulator with three hoses made of rubber etc. Connect with fork fittings, etc., and connect to the ship's compressor using a hose pipe made of rubber, etc. Each pressure regulator is mounted at a circumferential location parallel to the structural frame.

The float device has the function of supplying and discharging air and water, and the pressure regulator is always set to the deeper water side 71: when supplying the compressed air of the compressor to the tank of the float device.
F-) Install and connect in a way that allows air to be supplied to the tank of the device. If you use a compressor to supply compressed air to the float device when the seaweed net drying device is floating on the sea surface, the pressure regulator will always supply air to the float device on the deeper side of the sea surface, so that it is always level. It has a floating function, and the pressure is discharged into the sea from the supply and discharge port of one of the tanks of the pair of float devices, and the pressure can be adjusted naturally, so there is no risk of death.

In addition, by attaching an on-off valve to the end of the rubber hose connected to the seaweed net drying device floating on the sea surface and the compressor, and by sealing this valve, even if the hose is removed from the compressor, the float device A function that lifts seaweed nets from the sea surface for a long time by balancing the air pressure and water pressure of ffi! do.

Next, to submerge the seaweed net drying device, open the cock of the on-off valve attached to the end of the hose connected to the compressor, the air pressure will be reduced, water will enter from the tank supply/discharge port, and the tank will be connected to the tank. Water sinks and sinks from the two hoses connecting the two tanks to the two tanks. Of the two sides of each pair of tanks connected by the hoses, the tank on the side with the supply/discharge port is close to the water surface. By branching and connecting the hose from the side hose connection position, attaching a valve cock to the end of the hose, and opening this cock, you can sink the product more quickly. Furthermore, when the valve cock is closed and the device is submerged in water, the underwater weight of the seaweed net drying device can be freely adjusted by adjusting the air supply and discharge of each tank device.

(Embodiment) Next, an embodiment of the inventive device will be described in detail with reference to the drawings.
