Description

{Jellyfish polyp removal equipment}

The present invention eliminates the factors that inhibit attachment of useful seaweeds such as marine lime algae and inorganic limestone algae through the restoration of marine rocks through natural rock-like substrate restoration, A handle for sucking the injection water and moving the injection water to the injection hose at a high pressure to regulate the output of the injection water connected to the injection hose, a connection part composed of a body through which the injected water passes, And more particularly, to a seawater desalination apparatus comprising a nozzle.

In coastal area of Korea, there are many complicated causes such as the disappearance of the oceanic forests and the cracking of rocky algae which is hard calcareous algae like cement. It is a phenomenon in which calcium carbonate floating in a solid state in seawater appears as white as milk is scattered due to scattering of incident light. This dissolution phenomenon may be directly precipitated in seawater, crystallized on the surface of marine life, or attached to seabed rocks.

The solid calcium carbonate floats long in the seawater, slowly settles down to the bottom of the sea bed, bottom of the sea bed, and the bottom of the sea bed. The cause of this phenomenon has not yet been clarified, but it is assumed that it is related to the amount of calcium dissolved in seawater and the solubility of calcium carbonate with changes in water temperature.

This phenomenon was first discovered in Korea 's coastal waters in the late 1970s. After that, the frequency of occurrence of the phenomenon increased to the east coast of Yeongdeok - gun, Gyeongsangbuk - do, and Pohang and Youngilman in the late 1990s. As a result, various patterns of white matter with pink and white stuck on the rocky shore, accelerating the depletion of the ocean floor of the East Sea coast, such as abortion, sea urchin, and various other fish and shellfish dying.

It is difficult and time-consuming to restore the disk once it has progressed. Recently, researches on causes and countermeasures of coastal waters are proceeding, but systematic research through objective selection procedure for restoration of seagrass is not enough.

On the other hand, most of the jellyfish occur in semi-enclosed seaweeds or in environments where the food chain is broken due to changes in the marine environment. Recently, environmental pollution has caused the jellyfish living in the ocean to approach the water, In case of fishing using the net, the net is damaged due to the problem that most of the jellyfish are brought up in the net, and the price drops due to the freshness of the catch, delays in the work due to separation of the fish and jellyfish, The damage caused by the jellyfish has been extreme, including the loss of 2000-300 billion won in fisheries.

To prevent this, fishermen are making efforts to devote extra labor to remove the jellyfish polyp (larvae) from the unloading pier concrete walls and marine structures.

Polyp is a basic body type of tibia. Its body is cylindrical, and its tentacles are arranged around the mouth of the upper cortex. The body is made of a wide tongue, which is digested in the mouth of the food. do.

The larval stage polyp is attached to rocks and underwater structures. At this stage, large amounts of polyps are produced by asexual reproduction and propagated by the method of propagation. Polyps are like a hydra, but most of them are made up of many polyps, such as seaweed or hydra, forming a cluster like tree branches, and hydra bite is transformed into jellyfish and reproduced sexually if the polyp matures. The polyp removal method is generally a jellyfish polyp operation in which a jellyfish polyp is detached from the wall using a high-pressure jet, depending on the characteristics of the jellyfish not surviving at the bottom of the pearl.

Fig. 1 shows a conventional seaweed germination apparatus. Jellyfish polyps attached to natural rocks are generally removed from natural rock walls with polyps by water jetting, depending on the characteristics that can not survive on the bottom of the pearl. The polyp removal work was carried out by using manual and high-pressure sprayer to sweep the surface of natural rock by using cotton. One of the divers was ready to underwater, while one of the athletes assisted in the water. The relief work is carried out mainly in areas where the area density is high.

In the case of jellyfish polyp removal, considering that one individual is divided into 5,000 jellyfish, removal of polyps is necessary for smooth fishing activity. However, in order to remove jellyfish polyps attached to the underwater structure wall, There is a need for a device for mechanized jellyfish polyp removal that can maximize workforce efficiency and increase work efficiency because of the limitations and inefficiencies of working with manual work.

FIG. 10 is a principle view showing a jetting part of the seawater gon-washing device according to the present invention combined with a connecting part, and FIG. 11 is a side view of a jetting part of the seawater gyration device of the present invention. The jetting portion and the connecting portion are connected to each other via the fixing device 201 and the jetting portion may be formed of the jetting port 91, the bearing 92, the upper housing 93, the lower housing 94, and the rotary shaft 95.

The lower housing 94 may have a top, bottom, and outer wall structure, and is illustrated as a cylinder in the embodiment of the present invention. On one side of the lower housing corresponding to the connecting portion, a corresponding portion which can be connected to the fixed corresponding portion 200 of the connecting portion via the fixing device is formed. In an embodiment of the present invention, the corresponding portion of the lower housing is protruded to have the same structure as the pipe, and the lower housing corresponding to the corresponding portion is provided with an induction hole.

The fresh water or seawater moved to the induction hole is temporarily stored in the storage space and the water pressure is constantly applied to the storage space formed inside the lower housing having a relatively larger volume than the induction hole. A sloping passage connected to the storage space and inclined at a predetermined angle in a direction of the other side of the lower housing provided with the corresponding portion is formed up to the opposite side of the guiding hole of the lower housing so that fresh water or seawater accommodated in the storage space can be moved to the nozzle.

The inclined passage may be formed to have a relatively smaller diameter than the storage space and the corresponding portion through holes so that the velocity of the fluid moving to the inclined passage having a relatively small sectional area in the storage space having a relatively large sectional area according to the Bernoulli principle can be relatively increased . In addition, the cross sectional area of the storage space is curved toward the inclined passage, so that the injection water having a constant pressure coming from the corresponding through hole is smoothly moved to the inclined passage to reduce the pressure loss.

A rotary member is provided at a side center portion of the lower housing to allow the upper housing to rotate. The rotary member may be provided with a connection portion in the upper housing and a bearing 92 and a rotary shaft may be installed in the lower housing. The bearing is an example of a sub-concept constituting the rotating member, and may be selected from any of ball bearing, rolling bearing, roller bearing, and sliding bearing.

It is preferable that the upper housing 93 is formed to have a diameter suitable to correspond to the lower housing and the upper and lower surfaces, and the contact surface between the upper housing and the lower housing is made of a material and a surface hardly frictioned. The upper housing, which is in contact with the bearing of the lower housing, is rotatably mounted on the lower housing by rotating the rotary shaft. At least two through holes are formed at positions corresponding to the inclined passages, and jetting ports having different diameters are provided at positions where the through holes are formed, so that fresh water or seawater can be discharged through the inclined passage to the jetting ports.

12 shows the spraying principle of the seawater germination apparatus of the present invention. Since the upper housing is rotatable about the rotary shaft by the bearing but the lower housing is fixed and can not be moved, the user rotates the upper housing to correspond to the inclined passage and the jet port formed with various diameters.

A jellyfish polyp can be removed using a relatively small diameter jet opening in a tightly packed and tightly packed area, and a relatively large diameter jet opening can be used to remove jellyfish polyps in a wide area over the entire wall surface Efficient jellyfish polyps can be removed by injecting high-pressure water. Further, the high-pressure water can be easily blocked by associating the upper housing surface on which no through holes are formed with the inclined passage.

Hereinafter, the improvement of the fishing ground environment of the intertidal zone, the working method, and the results of the operation will be described with reference to concrete examples using the seaweed trough cleaning apparatus of the present invention.
