Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dragon boats, in particular to a dragon boat. Background Art
[0002] The dragon boat, a combination of the word "dragon" and "boat," is a dragon-shaped boat used for races during the Shangsi Festival and the Dragon Boat Festival. Dragon boat racing is a multi-person rowing competition, often held during festive occasions, and is now popular in China and several other countries and regions around the world. Initially, dragon boats were primarily wooden. This required a large amount of wood as a raw material, and wood was susceptible to mold when exposed to moisture. Consequently, dragon boats gradually evolved into fiberglass-reinforced plastic (FRP) boats. Today, FRP boats primarily consist of an outer hull and an inner hull, both made of FRP fiber. The rigidity of the inner hull provides sufficient structural strength for the outer hull. During production, the inner and outer hulls of the hull structure must be formed simultaneously, resulting in a complex molding process and low production efficiency. Utility Model Content
[0003] The purpose of the utility model is to solve the above technical problems and provide a dragon boat, which uses a support frame to replace the inner shell of the hull to provide support, thereby ensuring that the hull has sufficient structural strength. Compared with the hull structure in which the inner and outer double shells are formed at the same time, the manufacturing process of the hull structure is much simpler, which can effectively improve the manufacturing efficiency.
[0004] To achieve the above-mentioned purpose, the present invention provides the following solution: The present invention discloses a dragon boat, comprising a dragon head, a dragon body and a dragon tail, the dragon body adopts a hull structure, the hull structure comprises a support frame and a boat-shaped shell, the boat-shaped shell has a cabin, the support frame is erected in the cabin, the support frame is mainly composed of a keel and ribs, the dragon head is installed at the bow of the boat-shaped shell, the dragon tail is installed at the stern of the boat-shaped shell, the bottom surface of the boat-shaped shell is a concave arc surface, the concave arc surface makes the bottom of the boat-shaped shell an irregular "W" shape, the two sharp corners of the "W" shape form a balance watershed respectively, and the middle position of the "W" shape is the concave arc surface.
[0005] Preferably, the keel extends longitudinally along the hull, and the ribs are arranged at intervals along the extending direction of the keel.
[0006] Preferably, the support frame is a metal frame or a carbon fiber reinforced composite material frame.
[0007] Preferably, the ship-shaped hull is a carbon fiber reinforced composite material shell.
[0008] Preferably, the carbon fiber reinforced composite material shell adopts a carbon fiber reinforced composite material with carbon fiber as reinforcement and epoxy resin as matrix.
[0009] Preferably, a seat is included, and the seat is installed on the supporting frame.
[0010] Compared with the prior art, the utility model has achieved the following technical effects:
[0011] When manufacturing the hull structure, the utility model only needs to make the ship-shaped outer shell and then install the support frame to provide support, so as to ensure that the hull has sufficient structural strength. Compared with the hull structure in which the inner and outer double shells are formed at the same time, the manufacturing process is much simpler and the manufacturing efficiency can be effectively improved.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1
[0020] This embodiment provides a hull structure, such as Figures 1 to 4As shown, it includes a boat-shaped shell 2 and a support frame 3, and the boat-shaped shell 2 has a cabin. The support frame 3 is installed in the cabin of the boat-shaped shell 2 to support the boat-shaped shell 2 and provide sufficient structural strength. The support frame 3 is mainly composed of a keel 7 and ribs 8. The support frame 3 can effectively replace the inner shell. Compared with the hull structure of the inner and outer shells, which need to be formed at the same time, this hull structure only needs to make the outer shell (i.e., the boat-shaped shell 2) and install the support frame 3 to complete the production. The production process requirements for only making the outer shell are relatively simple, and installing the support frame 3 is even simpler. This hull structure can be widely used in various types of hulls, such as kayaks, dragon boats, etc. When using different types of hulls, the specific shape and structure of the boat-shaped shell 2 must meet the shape and structure requirements of the corresponding type of hull. The material of the boat-shaped shell 2 is selected according to needs.
[0021] In one embodiment, if Figures 1 to 4 As shown, the keel 7 extends longitudinally along the hull, and the ribs 8 are arranged perpendicular to the extending direction of the keel 7. There can be multiple keels 7, and the ribs 8 are arranged at intervals along the extending direction of the keel 7.
[0022] In one embodiment, if Figures 1 to 4 As shown, the support frame 3 is formed by integrally welding the keel 7 and the rib 8, or the support frame 3 is formed by anchoring the keel 7 and the rib 8 through anchoring pieces such as rivets and bolts.
[0023] In one embodiment, if Figures 1 to 4 As shown, the support frame 3 is a metal frame or a carbon fiber reinforced composite frame. Metal frames, such as aluminum frames, are lighter than steel frames and possess sufficient structural strength. This can minimize overall weight while ensuring sufficient structural strength, contributing to lightweighting. Of course, this does not preclude the use of other metal materials.
[0024] In one embodiment, if Figures 1 to 4 As shown, the aluminum frame is made of square aluminum tubes with hollow square ends, which significantly reduces weight while maintaining structural strength, further facilitating lightweighting. Of course, this does not mean that other aluminum components cannot be used. For example, triangular aluminum profiles, or aluminum profiles with L-shaped cross-sections, can also be used.
[0025] In one embodiment, if Figures 1 to 4 As shown, the boat-shaped hull 2 is a carbon fiber reinforced composite material shell. The carbon fiber reinforced composite material is lighter than fiberglass, which is conducive to lightweighting.
[0026] In one embodiment, if Figures 1 to 4 As shown, the carbon fiber reinforced composite material shell adopts a carbon fiber reinforced composite material with carbon fiber as reinforcement and epoxy resin as matrix.
[0027] Example 2
[0028] This embodiment provides a dragon boat, such as Figures 1 to 4 As shown, it includes a dragon head 1, a dragon body and a dragon tail (not shown). The dragon body adopts the hull structure of Example 1, wherein the specific shape and structure of the boat-shaped shell 2 must meet the shape and structure requirements of the corresponding type of hull. The dragon head 1 is installed at the bow of the boat-shaped shell 2, and the dragon tail is installed at the stern of the boat-shaped shell 2. To this end, a dragon tail mounting portion 5 can be specially provided at the stern of the boat-shaped shell 2 for the installation of the dragon tail. The dragon boat adopts the hull structure of Example 1, and its manufacturing process is relatively simple compared to the dragon boat formed by intersecting inner and outer shells, and the manufacturing efficiency can be relatively improved.
[0029] In one embodiment, if Figures 1 to 4 As shown, the boat also includes seats 4 mounted on the support frame 3. The number of seats 4 can be adjusted as needed, and they are arranged sequentially from the bow to the stern of the boat-shaped shell 2. The seats 4 can be plate-shaped members mounted on the support frame 3. The seats 4 can be made of wood, metal, or plastic. If the seats 4 are made of metal, they can be integrally formed with the support frame 3.
[0030] In one embodiment, if Figures 1 to 4 As shown, the bottom surface of the boat-shaped shell 2 is a concave arc surface 6, which makes the bottom of the boat-shaped shell 2 an irregular "W" shape. The two sharp corners of the "W" shape form a balance waterline respectively, and the middle position of the "W" shape is the concave arc surface 6, which is conducive to the balance of the dragon boat.
[0031] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
