Description

TECHNICAL FIELD [0001] The present invention relates to a wind deflector manufacturing unit for a ship, and a wind deflector manufacturing method using the wind deflector.

The present invention relates to a ship wind deflector production unit and a method of manufacturing a wind deflector using the same.

Recently, ships have become bigger, and research and development on environmentally friendly technology to reduce fuel cost due to rising energy prices are actively being carried out. At this time, the hull air resistance generated during the operation of the ship can contribute to the reduction of the fuel cost with a small reduction effect. A wind deflector is installed on the bow part as a method to reduce the hull air resistance. As an example, U.S. Pat. No. 4,843,997 (published Apr. 04, 1989) discloses a technique for a ship air (or wind) deflector installed at a bow section to reduce hull air resistance.

The strength of the wind deflector is very important because it must withstand high wind pressure. For this purpose, it is possible to fabricate a metal deflection type wind deflector by metal working and welding. However, in this case, while the manufacture of the wind deflector is easy, the larger the weight, the lower the working efficiency of the transportation and installation work.

To solve this problem, a composite material can be used for manufacturing a wind deflector. However, it is very difficult to fabricate a marine wind deflector, which is a single structure made of a composite material, unlike an existing manufacturing method such as an integral molding using a mold or a warm pressing molding method such as an aircraft manufacturing technique, such as a wind deflector for an automobile.

Also, since the composite material is weak to welding heat, it is not easy to manufacture a wind deflector through welding or to mount it on a hull. In addition, it is inconvenient in terms of cost-effectiveness to manufacture by a room temperature press molding method similar to that of a blade of a wind power generator.

However, this process is not necessarily performed, and the handle portion 420 may be kept in the locked state as described above. As described above, the wind deflector 300 can be effectively manufactured while repeating the above-described process.

Referring to FIG. 8, the height of the wind deflector 300 according to an embodiment of the present invention may be 75% or more of the height of the container 200 provided on the front of the ship. When the height of the container 200 provided on the front of the hull is H1, it is effective that the height H2 of the wind deflector 300 is 75% of H1. As a result of the wind tunnel test with the 12000TEU model, the hull air resistance was 88.4% as compared with the case where the wind deflector 300 was not installed in the case of H2 having the same H1. In the case of H2 with 75% of H1, hull air resistance was also 88.4%. This indicates that if the size is above a certain level, the expected effect is similar and the economic efficiency is lowered. H2, which is 75% of H1, the air flow passing through the wind deflector 300 does not hit the front surface of the container 200 but flows upward.

Likewise, the ship's wind deflector according to the embodiment of the present invention may have a width of 75% or more of the width of the container 200 provided on the front of the ship. When the width of the wind deflector 300 is 75% of the width of the container 200 provided on the front of the hull, the wind deflector 300 has the same result as above. When the width of the container 200 provided on the front of the hull is L1, it is effective that the upper width L2 of the wind deflector 300 is 75% of L1. 12000TEU model, it was 88.4% hull air resistance compared with the case without wind deflector 300 when L2 was the same as L1, and 88.4% when L2 was 75% Of the hull air resistance. This suggests that if the size is above a certain level, the expected effect is similar and the economic efficiency is reduced. That is, the air flow passing through the wind deflector 300 flows to the side without colliding against the front surface of the container 200.

The wind deflector 300 according to the embodiment of the present invention may have an optimal shape that minimizes hull air resistance. In order to compare wind deflectors 300 of various shapes, a wind tunnel test was performed on 12000 TEU, and it was found that the air deflector has a hull air resistance of 88.4% as compared with the wind deflector 300 without any deflector 300. In this experiment, H2 and L2 were all unified as control variables at 75% of H1 and L1.
