Description

Boat with foam-filled keel structure

The invention relates to a boat with foam-filled keel structure; in particular, it relates to a boat with foam-filled keel structure with a keel structure at the bottom of a buoyant body.

Rubber boats or boats filled with foamed materials have the characteristics of lightness, and boats filled with foamed materials have high strength and high load gravity, so they are widely used in various lifeboats, transport boats, fishing boats and other fields. .

A keel structure is provided at the bottom of a boat filled with conventional foamed material, which can be used to support the buoyancy body of the boat, thereby preventing the buoyancy body from bending. The keel structure has a downward depression shape, so that it forms a protrusion and a groove.

One of the purposes of forming grooves in the keel structure is to reduce weight. However, when the keel structure is set at the bottom of the bottom plate, the groove of the keel structure can be closed by the bottom plate to form a closed space, so the buoyancy of the boat itself can also be increased.

However, since the protruding portion of the keel structure is located below the water surface, there is a problem of accidental damage. When the keel structure is accidentally damaged, water will enter the keel structure, which will cause problems affecting the buoyancy of the hull.

In view of this, the inventors have been thinking hard, actively researching, adding years of experience in related product research, and after continuous testing and improvement, The invention has finally been developed.

An object of the present invention is to provide a boat with a foam-filled keel structure that prevents the keel structure from entering the water.

The features of the present invention that achieve the above-mentioned objectives include: a buoyancy body, which is generally tubular and generally U-shaped; and a bottom plate, which is provided at the bottom of the buoyancy body; and a tail plate, which is provided at the rear end of the buoyancy body and the bottom plate; A keel structure is provided at the bottom of the bottom plate; the keel structure has a downward depression shape, a convex portion is formed at the bottom thereof, and a groove is formed at the top thereof; the groove of the keel structure is filled with foam material.

Preferably, the bottom plate has at least one infusion port for injecting the foamed material into the groove of the keel structure, so that the foamed material can be easily poured.

Preferably, the keel structure is made of a hard and elastic composite material to reduce weight and increase strength.

Preferably, the keel structure is made of polymer fiberboard or fiber reinforced plastic (FRP) to reduce weight and increase strength.

Preferably, the foamed material is a foamable polymer material having a low specific gravity, thereby reducing weight.

Preferably, the foamed material is a foamable artificial resin material such as polyester amine or ethylene / vinyl acetate copolymer (EVA) to reduce weight.

In order to achieve the above and other objectives, the present invention adopts the technical means, components, and effects thereof. A preferred embodiment is illustrated below with reference to the drawings.

FIG. 5 is a schematic view of a part of the keel structure after the foam material is poured according to the present invention.

As shown in Figures 1 to 5, the foamed keel structured boat 100 of the present invention includes: a buoyancy body 1, which is generally tubular and generally U-shaped; and a bottom plate 2, which is provided at the bottom of the buoyancy body 1; and The tail plate 3 is provided at the rear ends of the buoyancy body 1 and the bottom plate 2; and a keel structure 4 is provided at the bottom of the bottom plate 2; the keel structure presents a downward depression shape, so that a convex portion 41 is formed at the bottom and made A groove 42 is formed on the top; the groove 42 of the keel structure 4 is filled with a foaming material 5 to achieve the purpose of preventing the keel structure 4 from entering water. This is explained in detail below.

1 to 4 are schematic diagrams before filling the groove 42 of the keel structure 4 with foam material. FIG. 5 is a schematic view after the groove 42 of the keel structure 4 is filled with foaming material.

The buoyancy body 1, the bottom plate 2 and the tail plate 3 can form a solid buoyancy body, which can be used, for example, to carry people or objects.

As shown in FIG. 2, the keel structure 4 may be fixed to the bottom of the bottom plate 2 by, for example, heat fusion. The keel structure 4 may be made of a material such as rubber, or may be made of a hard and elastic composite material such as a polymer fiber board or a fiber-reinforced plastic (FRP) to reduce weight and increase strength.

The keel structure 4 has a downward depression shape, forming a bottom The protruding portion 41 forms a groove 42 on the top thereof. The protruding portion 41 can adopt various shapes. For example, the bottom of the keel structure 4 protrudes downward from a generally quadrangular pyramid-shaped protruding portion 41 to support the buoyant body 1 and prevent the buoyant body 1 from bending to form a keel similar to a boat. Support effect. In addition, when the boat is moving forward, the protruding portion 41 of the keel structure 4 can be used to break the water to reduce the resistance and achieve the effect of improving the wave breaking performance. In addition, when the boat is receiving waves from the side, it can be borrowed. The keel structure breaks the waves to reduce the impact force and achieve the effect of improving the wave adaptability.

As shown in FIG. 3, after the keel structure 4 is provided at the bottom of the bottom plate 2, the groove 42 of the keel structure 4 can be closed by the bottom plate 2 to form a closed space. The main purpose is to use the keel structure 4 to support the buoyant body 1. One of the purposes of forming the groove 42 on the top of the keel structure 4 is to reduce weight.

As shown in FIGS. 4 to 5, an infusion port 21 may be provided on the bottom plate 2 so as to inject the foamed material into the groove of the keel structure, so that the foamed material can be easily poured. The foamed material 5 is a foamable polymer material having a low specific gravity, for example, a foamable artificial resin material such as polyester amine or ethylene / vinyl acetate copolymer (EVA).

The foam material 5 is filled in the groove 42 of the keel structure 4, which not only hardly increases weight, but also fills the groove 42 of the keel structure 4, so as to prevent the keel structure 4 from entering water. Therefore, even when the keel structure 4 is damaged, there is no doubt that the groove 42 of the keel structure 4 will enter the water.

The above-mentioned embodiments in this case are provided for convenience of explanation only. When the meaning of this case cannot be limited in this way, that is, all kinds of transformation designs based on the scope of patent applications listed should be included in the scope of patents in this case.
