专利说明:

Small vessel made of polyethylene.
The present invention relates to various ships, and more particularly to a small ship of polyethylene material.
Typically, small vessels made of Fiber Reinforced Plastics (FRP) are available in a variety of ways, such as moving forward when people simply paddle and speeding up by installing propellers at the back of the vessel. It is mainly used for recreation and transportation in river or lake. However, the FRP small vessel as described above has a very light weight of the hull and is swept away by waves or tidal currents, causing rolling (rolling: left and right rocking) and pitching (pitching: rocking). In addition, the conventional FRP small ship has a problem that the light weight is not only poor linearity, but also excessive fuel consumption, and the steering ability is significantly reduced.
Accordingly, an object of the present invention to provide a small ship of polyethylene material that can prevent the rolling and pitching phenomenon.
Another object of the present invention is to provide a small vessel of polyethylene material that can improve the straightness and steering efficiency by installing a guide-bracket in the center of the bottom of the small vessel.
In order to achieve the above object, the small ship of the present invention has an outer skin layer and an inner skin layer made of polyethylene, and an intermediate layer is formed by foaming polyethylene and a foam molded product in the middle thereof. Inverted triangular shaped guide-bracket having a portion is characterized in that the fixed installation.
1 is a perspective view showing the bottom structure of a small ship of polyethylene material according to an embodiment of the present invention.
2 is a cross-sectional view showing the structure of a small vessel made of polyethylene of the present invention.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In the following description, it should be noted that only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to obscure the subject matter of the present invention.
1 and 2 show the structure of a small vessel made of polyethylene in accordance with one embodiment of the present invention. Referring to FIG. 2, a molded plate of polyethylene includes an outer shell layer 12 and an inner shell layer 16, in which polyethylene and a foamed molded product are filled in the middle thereof to form a main body of the small ship 10, and the small ship 10 At the back of the propeller 20, which generates a predetermined driving force, is installed, and an inverted triangular guide-bracket 14 is fixedly installed at the center of the bottom.
The main body constituting the small vessel 10 is first formed by molding the outer shell layer 12 with polyethylene as shown in the outer shape of the main body, and then secondly synthesized polyethylene and a foaming agent, and then inside the outer shell layer 12 By adsorbing, the intermediate layer 14 is molded. Then, the inner body of the intermediate layer 14 is integrally molded with the whole as a polyethylene molded plate to complete the body having the endothelial layer 16. In addition, the guide-bracket 18 is installed along the center of the bottom portion of the small vessel 10 by a plurality of screws 18a long before and after. In addition, the guide-bracket 18 is formed in an inverted triangle shape having a space portion 18b therein, and as shown in FIG. The space portion 18a serves to hold the center of gravity of the small ship 10. In other words, when the small vessel 10 is advanced at a predetermined speed, the flowing water is generated by friction with the inner surface of the guide-bracket 14 while the water flowing out through the space 18a to the rear. At this time, this force is to hold the center of gravity of the small vessel (10).
As described above, the present invention forms the outer layer and the endothelial layer with a molded plate of polyethylene and foams the polyethylene and the foamed molding in the middle to form the intermediate layer, thereby making the material itself lighter than water and increasing the overall weight. Even if water enters the ship, the ship will not sink and minimize the ship's movements such as rolling and pitching. In addition, by installing a reverse triangular guide-bracket at the center of the bottom of the small ship, the steering efficiency can be remarkably improved, and the osmotic pressure is generated as the water is filled inside the guide-bracket and the center of gravity is held. (By forming), it is possible to realize the straightness and stability of the small ship, and the guide bracket is located on the bottom of the propeller, so that the floating floats (nets, water plants, etc.) floating on the sea to both sides or sent to one side. By doing so, there is an effect of preventing the phenomenon of the floating of the float on the propeller.
