Description

Red tide removal apparatus and method

The present invention relates to a ship-type red tide removal device and a method thereof, and more particularly, to a ship-type red tide removal device and method for removing the red tide by forcibly lowering the surface water to eject into the deep sea.

As is well known, nutrients composed of phosphorus, nitrogen, and organic substances from detergents, phosphate, livestock, and plant waste and waste water due to pollution by domestic sewage, livestock wastewater and factory wastewater form the body of phytoplankton or seaweed. It is the basis for red tide growth, and more than 80% of these nutrients flow from land.

Recently, the red tide, which is heading north along the South and East coasts, is becoming a highly diseased phenomenon that occurs frequently along the coast of the Korean Peninsula. Experts report that red tide is rising due to the massive inflow of wastewater and high temperature along with industrial development. have.

In general, red tide is mostly caused by large amounts of fish excretion feed residues in polluted rivers or river farms, and the red tide's proliferation and diffusion causes significant ocean problems in the following environments.

When the amount of sunshine increases and nutrients such as nitrogen (N), phosphorus (P), and iron (Fe) are high, the water temperature diffuses through mass propagation when the temperature is maintained at 20-25 ° C.

These red tides are adsorbed by the gills of fish in the marine ecosystem and suffocate, causing death and depletion of oxygen. In other words, the red tide is an organic substance in the aquatic system. do.

In particular, Cochlodinium, a type of phytoplankton, has the nickname of Korean red tide, and has been causing great damage only on the toxic Korean coast since the 1990s. When coclodinium (15 ~ 20㎛), one tenth the diameter of the hair, is breeding, the seawater becomes dark red.
As a method for removing such red tide, the method of removing red tide by sprinkling ocher is required to crush a large amount of yellow soil, transport it to a barge, mix it with water, and then spray it. There is a problem that can not be handled.
On the other hand, Republic of Korea Registered Room No. 0412858, "red tide removal system using a ship" is disclosed, which lowers the water temperature in the red tide occurrence area by using the vessel to raise the water in the lower layer in the sea to spray on the upper layer where the red tide occurred. It is to remove the red tide.
However, in order to lower the temperature of surface water rising to 20 ~ 25 ℃ in the summer below 13 ℃ which can remove red tide, a large amount of deep water must be sprayed, and it is not applied to reduce the temperature in a short time and the cost is excessive. There is a problem that occurs.

As shown in FIG. 4, the lowering means 4 is connected to the propulsion device 80 of the ship 100 to receive the rotational force, the first lowering means 4a of the propulsion device 80 of the ship 100. The bevel gear 9 "is connected, and the first lowering means 4a and the remaining lowering means 4b, 4c, 4d ... are also connected by the bevel gear 9", thereby the propulsion device of the ship 100. By the rotational force of 80, both the first lowering means 4a and the remaining dependent lowering means 4b, 4c, 4d ... are also rotatable.

Here, the propulsion device 80 includes a conventional engine as a power means for advancing or reversing a ship, which will be omitted because it is a known technical configuration.

The pulleys 44 of the plurality of lowering means 4, the connecting means 9 and the main power source 8 connecting them are installed to be embedded in the buoyancy plate 2 or to the outside to prevent the penetration of moisture. It is installed but made of a structure in which the waterproof cover 10 is mounted.

In addition, as shown in FIG. 5, the lowering means 4 is installed to be inclined toward the rear to face the traveling direction of the ship 100 in order to further reduce water resistance as in the water collecting member 6.

Therefore, since the lowering means 4 is inclined toward the rear side, the lowering means 4 may be utilized as a propulsion force, so that forward movement is possible at a low speed without operating the propulsion device of the vessel 100, and thus fuel required for the propulsion of the vessel 100 may be utilized. The effect can be reduced.

The operation relationship of the red tide removing device according to the first embodiment of the present invention configured as described above will be described.

The shaft 42 of the lowering means 4 is installed vertically downward on the buoyancy plate 2. That is, the bearing 29 is mounted on the buoyancy plate 2, and the shaft 42 is fitted to the bearing 29 to be coupled thereto, but the shaft 42 is installed to be inclined backward by about 15 to 25 °.

On the other hand, the collecting member 6 is installed to be located behind the lowering means 4, and is preferably installed to be inclined toward the rear at the same angle as the shaft 42.

In addition, as shown in Figure 2, the collecting member 6 is installed vertically downward so as to face the fuselage 120 of the vessel 100, while the opening is configured to face the front.

The coupling is completed by installing the buoyancy plate 2 equipped with the lowering means 4 and the collecting member 6 in the shape of a wing on the body side of the vessel 100 (see FIG. 6).

Thereafter, when the vessel 100 moves to the red tide position and operates the lowering means 4, the downward flow of water is formed by the thrust generated by the rotation of the screw 46 and the impeller 47.

Therefore, when the surface water is ejected and moved to the lower portion by the downward flow, when plankton mainly inhabiting the surface water of high temperature is moved to the lower portion of the lower temperature, red tide can be removed because the temperature shock and photosynthetic metabolism are stopped and killed.

In general, the rate of red tide is high during the hottest summer season, and the surface water temperature at this time is about 20 to 25 ° C. However, the low-temperature environment below 13 ° C and the environment for preventing photosynthetic metabolism are formed in the lower layer of the sea below 10m. will be.

That is, the depth of sunlight can penetrate through the surface of the water is about 2 ~ 3m, so the temperature of 10m in the water is a low temperature environment that can not grow plankton causing red tide.
