Hereinafter, referring to FIGS. 1 and 2, a marine life repelling apparatus according to an embodiment of the present invention will be described. In the present invention, examples of marine life may include sharks, but are not limited thereto.

1 is a perspective view illustrating a marine life repelling apparatus according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken from AA ′ of FIG. 1.

1 and 2, the marine life repelling apparatus 1 according to an embodiment of the present invention is buoy 10, the magnetic field generator 20, the solar cell module 30, the ultrasonic generator 40 and It may include a bottom weight (50).

The buoy 10 floats on the water, and the buoyancy can be automatically adjusted in response to the height change of the sea level. In the present invention, the change in the height of the sea level may include a change in the height due to the difference between the height of the sea level due to the current, waves and tides, but is not limited thereto. The buoy 10 may also include, for example, a first chamber 10a, a second chamber 10b and a blast pump 10c.

Specifically, the first chamber 10a and the second chamber 10b of the buoy 10 may be stacked on each other.

For example, the first chamber 10a may be stacked on top of the second chamber 10b and may include an empty space. Herein, the size of the empty space may include the minimum size of the space for the buoy 10 to have its own buoyancy. In other words, due to the empty space, the buoy 10 can itself have a positive buoyancy.

The second chamber 10b may be disposed at the lower end of the first chamber 10a.

The second chamber 10b may include, for example, a blasting space for adjusting the amount of buoyancy. Specifically, the liquid 13 used to adjust the buoyancy may be included in the second chamber 10b. That is, the buoyancy of the second chamber can be adjusted according to the amount of liquid 13. In general, the liquid 13 for adjusting the buoyancy may include water, but is not limited thereto.

The ballast pump 10c may be formed at the lower end of the second chamber 10b. Also, the blast pump 10c may specifically perform blasting and de-ballasting operations.

Here, the blasting operation flows the liquid 13 into the second chamber 10b in order to adjust the buoyancy of the marine life repelling apparatus 1 (

Work to include. In addition, in the case of the develating operation, the liquid 13 in the second chamber 10b is discharged to the outside of the second chamber 10b as opposed to the blasting operation. A detailed description of the operation of the ballast pump 10c will be described later.

In addition to the first chamber 10a, the second chamber 10b, and the blast pump 10c, the buoy 10 has a through hole 15 penetrating the center of the first chamber 10a and the second chamber 10b. It may further include.

In detail, the through hole 15 is formed through the centers of the first chamber 10a and the second chamber 10b, thereby connecting the solar cell module 30 and the first electrode 21 to each other. 17) can serve as a pathway.

The magnetic field generator 20 is formed at the bottom of the buoy 10 and may generate a magnetic field for repelling marine life. That is, by the magnetic field generated by the magnetic field generator 20, access to marine life, in particular dangerous marine life such as sharks, can be blocked.

In addition, the magnetic field generator 20 may include a first electrode 21, a second electrode 24, a second cable 22, and a length adjuster 23.

For example, the first electrode 21 may be formed in the through hole 15 at the bottom of the second chamber 10b.

In detail, the first electrode 21 may be connected to the solar cell module 30 and the first cable 17 to receive power required to generate a magnetic field from the solar cell module 30. In addition, the first electrode 21 may include an anode, but is not limited thereto. The first electrode 21 may be connected to the second electrode 24 through the second cable 22 to generate a magnetic field.

The second electrode 24 may be formed to be spaced apart from the first electrode 21 and the second cable 22.

In detail, the second electrode 24 may include an electrode having a different polarity from that of the first electrode 21. In addition, the second electrode 24 may be close to or far from the first electrode 21 according to the height change situation of the sea level by the length adjuster 23 for adjusting the length of the second cable 22. have.

Herein, the intensity and range of the magnetic field generated by the first electrode 21 and the second electrode 24 may be adjusted according to the distance between the first electrode 21 and the second electrode 24. That is, when the distance between the first electrode 21 and the second electrode 24 increases, the range of the magnetic field becomes wider, but the intensity decreases, and the distance between the first electrode 21 and the second electrode 24 increases. As you get closer, the magnetic field can be narrower and stronger.

The second cable 22 may connect the first electrode 21 and the second electrode 24 to each other.

Specifically, the second cable 22 connects the first electrode 21 and the second electrode 24, and the length may be adjusted by the length adjuster 23. The length of the second cable 22 can be adjusted according to the height change situation of the sea level by the length adjuster 23, a detailed description thereof will be described later.

The length adjuster 23 may adjust the length of the second cable 22.

Specifically, the length adjuster 23 may reduce the length of the second cable 22 at low tide, so that the second cable 22 does not bend, even in a state where the depth of water is lowered, to maintain a straight shape. In addition, by increasing the length of the second cable 22 at high tide, a magnetic field can be generated according to the depth of the deep water.

The solar cell module 30 may be formed on the buoy 10.

Specifically, the solar cell module 30 may be formed on the buoy 10, and may supply power to the magnetic field generator 20. That is, the solar cell module 30 converts solar energy into electrical energy and supplies power to the first electrode 21 through the first cable 17, thereby generating a magnetic field in the magnetic field generator 20. Make sure

The ultrasonic generator 40 may be connected to the second cable 22.

In detail, the ultrasonic generator 40 may be connected to the second cable 22 to generate ultrasonic waves for repelling marine life in the water. The ultrasonic waves generated by the ultrasonic generator 40 may efficiently repel marine life together with the magnetic field generated by the magnetic field generator 20.

The bottom weight 50 may be connected to the lower end of the second electrode 24.

In detail, the bottom weight 50 is connected to the lower end of the second electrode 24, and the weight is applied to the second electrode 24 so that the first electrode 21 and the second electrode 24 are spaced at a predetermined interval. Can be added. That is, even if the length adjuster 23 adjusts the length of the second cable 22 according to the change in the height of the sea level, the force or weight for pulling the second electrode 24 in the first direction DR1 is not properly applied. If not, it may be difficult for the second cable 22 to remain straight in water. In addition, when the buoy 10 is continuously swept away by the current, the marine life cannot be blocked at the desired position, so that the bottom weight 50 is connected to the lower end of the second electrode 24 to form the buoy ( The effect of fixing 10) to a desired position can be obtained.

Here, the predetermined interval between the first electrode 21 and the second electrode 24 may include an interval in which a magnetic field can be generated. That is, it means an interval greater than or equal to the minimum interval required for the magnetic field to be generated.

The marine life repelling apparatus 1 according to an embodiment of the present invention uses the solar cell module 30 to cover electric power required for generating a magnetic field, and generates ultrasonic waves as well as magnetic fields to more efficiently prevent dangerous marine life. Can be repelled. In addition, the buoyancy of the buoy 10 and the length of the second cable 22 is automatically adjusted according to the change of the sea level, so that it can be used in the region where the difference of the sea level is large, for example, the west coast of Korea. There is this.

Referring to FIG. 3, the array 100 may include a plurality of marine

life repelling devices

1, 2, and 3. In FIG. 3, only three marine life repelling devices are illustrated, but are not limited thereto. That is, the array 100 may include three or more marine living repelling devices. In addition, the plurality of marine life repelling devices (1, 2, 3) may each include the same device as the marine life repelling device (1) according to an embodiment of the present invention.

In detail, the plurality of marine

life repelling devices

1, 2, and 3 of the array 100 may be tethered to each other by the rope 100. That is, it may be fixed by being tied to each other by the rope (100). At this time, the plurality of marine life repelling device (1, 2, 3) is arranged in the same direction, may serve as a wall (wall) to prevent the access of marine life.

As can be seen from Figure 3, when the plurality of marine life repelling device (1, 2, 3) arranged in the same direction, each magnetic field may be spaced apart by a distance such that adjacent to each other. In other words, each magnetic field may be generated adjacently so that it is difficult for marine organisms to pass through the magnetic field walls generated by the plurality of marine

organism repelling devices

1, 2, 3.

Array 100 according to another embodiment of the present invention by forming a marine life access barrier using a plurality of marine life repelling device (1, 2, 3), it is possible to effectively block the access of marine life to a specific area Can be.

4 and 5 are conceptual views illustrating the operating method of FIG. 1.

4 is a conceptual view illustrating an operation method of the marine life repelling apparatus 1 at low tide.

Specifically, at low tide, since the depth of the water becomes shallow, the necessity of shortening the length of the second cable 22 arises. Accordingly, the length of the second cable 22 is reduced by the length adjuster 23, and the buoy 10 may rise in the second direction DR2 due to an increase in buoyancy by the velast pump 10c. In this case, the buoyancy of the buoy 10 increases because, when the water depth becomes shallow at low tide, if the length of the second cable 22 is randomly reduced, the minimum distance required for generating the magnetic field (that is, the first electrode ( The gap between 21) and the second electrode 24 may not be secured, so the minimum gap is secured.

Accordingly, as the liquid 13 in the blast pump 10c flows out, the buoyancy of the buoy 10 is increased, and the length adjuster 23 is in equilibrium with the force pulling the upper end of the second cable. The first electrode 21 and the second electrode 24 can be maintained at an appropriate interval (that is, the minimum interval for generating a magnetic field).

In detail, the length adjuster 23 pulls the second cable 22 positioned at the upper end of the length adjuster 23 in the first direction DR1, and the second cable 22 positioned at the lower end of the length adjuster 23. It may be pulled in the second direction DR2. At the same time, the buoy 10 is in equilibrium with the force by which the length adjuster 23 pulls the upper end of the second cable by pulling the second cable 22 in the second direction DR2, so that at least the It is possible to secure the interval of.

5 is a conceptual diagram illustrating a method of operating the marine life repelling apparatus 1 at high tide.

Specifically, when the tide is high, the depth of the water is deepened, the need arises that the length of the second cable 22 is long. Accordingly, the length of the second cable 22 is increased by the length adjuster 23, and the buoy 10 may sink in the first direction DR1 due to the decrease in buoyancy by the velast pump 10c. At this time, the buoyancy of the buoy 10 is reduced, because when the tide, when the depth of the water deepens, the current is stronger, the buoy 10 is more likely to be swept by the current, preventing this, buoy 10 ) To where you want it. In other words, when the depth of the water deepens, the buoy 10 needs to have a weight (that is, a weak buoyancy) to the extent that it is not floated by the current, so that the buoyancy of the buoy 10 is reduced. In addition, if the length of the second cable 22 is increased more than necessary, the range between the buoy 10 and the bottom weight 50 may be reduced since the range of the magnetic field may be widened more than necessary and the strength may be less than necessary. The length of the second cable 22 needs to be increased to the extent that the second cable 22 can maintain a straight line shape.

Therefore, as the liquid 13 flows into the blast pump 10c, the buoyancy of the buoy 10 is reduced, and the second cable 22 is straightened by the support of the bottom weight 50 and the buoy 10. The length of the second cable 22 is increased enough to maintain the shape.

As a result, the length adjuster 23 fixes the second cable 22 positioned at the top of the length adjuster 23, and moves the second cable 22 positioned at the bottom of the length adjuster 23 in the first direction DR2. Can be increased. At the same time, while the buoy 10 sinks in the first direction DR1 while being fixed with the second cable 22, a gap for generating a magnetic field may be secured. That is, since the bottom weight 50 and the buoy 10 having the reduced buoyancy have a weight such that they are not swept by the current, a magnetic field may be generated around the second cable 22 having an increased length.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
