1 to 3 are illustrated for the jellyfish polyp removal vessel using the cavitation according to the present invention. Under the body of the ship is provided a device for removing jellyfish polyps underwater. An apparatus for removing jellyfish polyps may be provided to allow height adjustment in water. The removal device is attached to an unmanned aquatic robot (USV) or an unmanned submersible (UUV) to remove jellyfish polyps by accessing natural objects such as rocks in the water where jellyfish polyps are attached, or artificial objects such as seawalls.

4, an operation explanatory diagram of the jellyfish polyp removal device using the cavitation according to the present invention is shown.

Apparatus for removing jellyfish polyps according to an embodiment of the present invention, the front of the housing 10, the grid-shaped grid 11 provided in front of the housing 10 to prevent the inflow of foreign matter. And a high pressure injection device 12 provided in the housing 10 for separating the jellyfish polyps from the underwater features, and the jellyfish polyps passing through the grid 11 to the interior of the housing 10. An orifice member (13) having a rotating fan (15) provided to be sucked into the air, a plurality of orifices (131) which are broken by passing the sucked jellyfish polyps, and a rear of the orifice member (13), And a pipe member 14 for generating cavitation in the housing 10.

In the present invention, the orifice member 13 may be provided at either the front or the rear of the rotary fan 15.

The structure of the housing 10 is as shown in FIG. The front is open to the grid 11 is installed, the rear is a structure that can increase the discharge rate of the fluid introduced to the front through the pipe member (14). Although the cross section of the housing 10 is shown in a circular shape, it is also possible to have various cross sections without being limited thereto.

The grid 11 is to prevent the entry of foreign matter into the housing. In general, jellyfish polyps are about 1-2 mm in size. Therefore, the jellyfish polyps need to be slightly larger than this (eg 2.2 mm) in order to flow into the housing. However, when manufacturing too large, large foreign matter other than jellyfish polyps may be introduced into the housing, which may cause problems in the operation of the pump and the orifice, which is not preferable.

In addition, the grid 11 may be utilized for cutting jellyfish floating in the water, without merely preventing the inflow of foreign foreign matter. The grid 11 may additionally have a function of removing jellyfish in the water, and for this purpose, the grid 11 is formed of a material capable of removing the jellyfish, such as a thin wire or a piano wire, and is formed in a grid shape so that the jellyfish can be cut by passing. Can be. Here, removal is a term that includes the meaning of cleavage. The body of the jellyfish can be cut finely by the blades of the grid and the rotating fan.

The main feature of the present invention is to provide a high pressure injection device (12). The high pressure jetting device 12 may be an ultrasonic probe or a device for ejecting pearl or sand at high pressure. This removes the polyp attached to the feature or man-made structure. Underwater features in the present specification are to be understood as a concept including both natural materials such as rocks in the water or artificial materials such as embankments.

Referring to FIG. 4, the jellyfish polyps 101 of the terrain are separated by the energy ejected from the high pressure injection device 12 at high pressure. However, at the same time, the large foreign objects 102 that have settled on the terrain are also mixed with the jellyfish polyps 101 which are removed at the same time, which is filtered by the grid 11 located in front of the housing described above.

The high pressure injection device 12 is preferably located in front of the jellyfish polyp removal device. This is because the efficiency of the device is located in the front of the moving direction of the jellyfish polyp removal device.

Substances suspended by the high pressure injection device 12 are sucked into the housing using a pump (eg centrifugal pump) or a screw. In FIG. 4, external foreign matter is sucked into the inside by the pump 16 provided inside the housing. In addition, the rotary fan 15 may be further used to assist the suction function of the pump 16. The rotary fan 15 may also serve as a suction function alone.

At this time, among the suspended matter, objects of a size that can block the holes of the orifice installed in the rear of the device are filtered by the grid in front of the device. Therefore, the shape of the grid is preferably provided in a conical shape as shown in the figure.

The greatest feature of the present invention resides in an orifice member 13 provided at the rear of the rotating fan and having a plurality of orifices 131 which are broken by passing through the jellyfish polyps.

4 and 5, jellyfish polyps 101 passing through the orifice 131 are crushed 102 behind the orifice member 13 by cavitation. The diameter of the orifice 131 is characterized in that it is formed somewhat larger than the diameter of the jellyfish polyps.

Therefore, the diameter of the orifice is preferably provided a little larger than the jellyfish polyps, and it is preferable that the diameter of the orifice is equal to or slightly larger than the grid spacing of the grid (for example, 2.4 mm).

Among the floats sucked at high speed, jellyfish polyps passing through the grid 11 are instantaneously generated while passing through the orifice behind the device, and are broken by the explosive minute high temperature and high pressure air bubbles.

In the case of crushing using such a cavitation, sperm or eggs are ejected from the jellyfish, and thus there is an advantage in that a function of preventing the regeneration of the jellyfish occurs.

The rotary fan 15 has an auxiliary function of the pump 16 for suction into the removal device, and the grid of the grid 11 installed on the front of the device may be blocked, so that the rotating fan 15 is rotated in the opposite direction to the suction to clean the grid. Perform the function of maintaining. Therefore, it is preferable to use a motor capable of rotating in both directions as the motor for rotating the rotary fan 15.

In addition, since the present invention is characterized in that the jellyfish polyps are removed by using the cavitation, a pipe member 14 provided at the rear of the orifice member 13 and generating the cavitation in the housing 10 is provided. Should be provided. The pipe member 14 is characterized in that the cross-sectional area is reduced from the front to the rear. Cavitation may occur in the housing by the pipe member 14.

Through this, the ejection flow and the pressure discharged from the pipe member 14 located behind the jellyfish polyp removal device are used to directly eject pearl or sand at a high pressure, without using high pressure pearl, sand, or ultrasonic probe. It is also possible to remove polyps that are attached to water or structures.
