Detailed implementation manners

[0023] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. Based on the embodiments in the implementation manners, it is intended to explain the present application and should not be construed as a limitation to the present application.

[0024] As used in this specification, the phrase "in one embodiment" or "example" or "instance" means that the specific features, structures, or characteristics described in connection with the embodiment itself can be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" at various positions in the specification does not necessarily refer to the same embodiment.

[0025] As Figure 1 , Figure 2 shown, this embodiment provides a catamaran connection structure for connecting the first hull 1 and the second hull 2 of the catamaran. Both the first hull 1 and the second hull 2 include a deck 3 and opposite inner ship's sides 4. The connection structure includes a first connecting piece 10, a second connecting piece 20, and a connection frame 30. The first connecting piece 10 is fixedly connected to the decks 3 of the first hull 1 and the second hull 2. The second connecting piece 20 is fixedly connected between the opposite inner ship's sides 4 of the first hull 1 and the second hull 2. The connection parts 21 of the second connecting piece 20 with the first hull 1 and the second hull 2 are both set as arcs extending towards the inner ship's side 4. The connection frame 30 is fixedly connected between the first connecting piece 10 and the second connecting piece 20.

[0026] By providing the first connecting piece 10 at the decks 3 of the first hull 1 and the second hull 2 and providing the second connecting piece 20 between the opposite inner ship's sides 4 of the first hull 1 and the second hull 2, a firm connection is formed between the first hull 1 and the second hull 2 to form a catamaran. By setting the connection parts 21 of the second connecting piece 20 with the first hull 1 and the second hull 2 as arcs extending towards the two inner ship's sides 4, the force on the second connecting piece 20 and the two inner ship's sides 4 is more uniform and dispersed, preventing stress concentration at the connection between the second connecting piece 20 and the two inner ship's sides 4 from causing deformation and fracture, and improving the connection strength and connection stability of the catamaran.

[0027] Specifically, as Figure 2 shown, on the surface of the second connecting member 20 facing the outer sides of the first hull 1 and the second hull 2, there is a skin layer 22 integrally formed with the inner shipboard 4 of the first hull 1 and the second hull 2. The skin layer 22 forms a streamlined curved surface at the connecting portion 21 between the second connecting member 20 and the first hull 1 and the second hull 2. The skin layer 22 can play a role in protecting the hull and enhance the connection strength and stability of the outer surface body at the connecting portion 21 between the second connecting member 20 and the first hull 1 and the second hull 2.

[0028] Specifically, as Figure 3 shown, a plurality of connecting frames 30 are provided. The connecting frame 30 includes an upper frame 31, a lower frame 32, and side frames 33 fixedly connected between the upper frame 31 and the lower frame 32. The upper frame 31 is fixedly connected to the first connecting member 10, the lower frame 32 is fixedly connected to the second connecting member 20, and the side frames 33 are fixedly connected to both end portions of the upper frame 31 and the lower frame 32. The connecting frame 30 can enhance the overall connection strength of the connection structure, make the force of the entire connection structure more uniform, and prevent local damage and deformation of the connection structure due to stress concentration. As an exemplary embodiment, as Figure 2 shown, two connecting frames 30 are provided, respectively located at both end portions of the first connecting member 10 and the second connecting member 20. Obviously, the connecting frame 30 can also be set to any other number and located at any position between the first connecting member 10 and the second connecting member 20. Usually, the connecting frames 30 are evenly arranged between both end portions of the first connecting member 10 and the second connecting member 20. By increasing the number of connecting frames 30, the connection strength of the connection structure can be increased to a certain extent, but correspondingly, the weight of the connection structure will be increased.

[0029] As a implementation manner, as Figure 3 shown, the connecting frame 30 is set as an integral structure. The connecting frame 30 with an integral structure has better connection strength. In other embodiments, the connecting frame 30 can also be set as a split structure and fixedly connected by connecting members or connection methods to form the connecting frame 30.

[0030] As a implementation manner, as Figure 1 、 Figure 2As shown, a connecting angle iron 40 is provided at the connection between the connecting frame 30 and the first connecting member 10 and the second connecting member 20. The connecting frame is also fixedly connected to the decks 3 of the first hull 1 and the second hull 2 through the connecting angle iron 40. By providing the connecting angle iron 40 at the connection between the connecting frame 30 and the first connecting member 10 and the second connecting member 20, a stable fixed connection can be formed between the connecting frame 30 and the first connecting member 10 and the second connecting member 20, thereby increasing the overall connection strength of the connection structure; by providing the connecting angle iron 40 between the connecting frame 30 and the decks 3 of the first hull 1 and the second hull 2, the connection strength between the overall connection structure and the first hull 1 and the second hull 2 can be enhanced, making the connection between the connection structure and the first hull 1 and the second hull 2 more stable. It should be noted that the connecting angle iron 40 in this embodiment can also be replaced by other connecting fasteners with the same or similar functions, and the specific form of the connecting fastener is not limited in this embodiment.

[0031] As an implementation manner, the connecting angle iron 40 is fixedly connected to the first connecting member 10, the second connecting member 20, and the connecting frame 30 through one or more of the connection methods of bonding, threaded connection, and welding. Connection methods such as bonding, threaded connection, and welding are all to form a stable connection relationship between the connecting angle iron 40 and the first connecting member 10, the second connecting member 20, and the connecting frame 30. Multiple methods can be used simultaneously to jointly play the role of fastening connection, or other connection methods that can achieve the same function can be used for connection, which is not limited in this embodiment.

[0032] As an implementation manner, the first connecting member 10 includes a plurality of cross beams connected between the first hull 1 and the second hull 2. Specifically, the first connecting member 10 is formed by closely arranging and splicing a plurality of the cross beams. By a plurality of discretely arranged or closely arranged cross beams, the first hull 1 and the second hull 2 can be fixedly connected to form a catamaran, and the connection stability of the catamaran can be increased, thereby enhancing the wave resistance of the catamaran.

[0033] As an implementation manner, as Figure 1 、 2 shown, the second connecting member 20 and the inner ship sides 4 of the first hull 1 and the second hull 2 are provided as an integral structure. Setting the second connecting member 20 and the inner ship sides 4 of the first hull 1 and the second hull 2 as an integral structure can further improve the connection strength between the second connecting member 20 and the first hull 1 and the second hull 2. At the same time, the force on the connection part 21 between the second connecting member 20 and the first hull 1 and the second hull 2 is more uniform, avoiding damage to the connection part 21 between the second connecting member 20 and the first hull 1 and the second hull 2 due to excessive local stress.

[0034] In addition, this embodiment also provides a catamaran, as Figure 1As shown, it includes a first hull 1 and a second hull 2, and a catamaran connection structure as described in any one of the technical solutions in the above embodiments is provided between the first hull 1 and the second hull 2. The reasoning process of the beneficial effects of the catamaran provided in this embodiment is similar to that of the foregoing catamaran connection structure, and will not be elaborated here.

[0035] In summary, for the catamaran connection structure and the catamaran in this embodiment, by providing a first connecting member 10 at the deck 3 of the first hull 1 and the second hull 2, and a second connecting member 20 between the opposite inner ship sides 4 of the first hull 1 and the second hull 2, a firm connection is formed between the first hull 1 and the second hull 2 to form a catamaran. By setting the connection part 21 of the second connecting member 20 with the first hull 1 and the second hull 2 as an arc extending towards the two inner ship sides 4, the force on the second connecting member 20 and the two inner ship sides 4 is more uniform and dispersed, preventing stress concentration at the connection between the second connecting member 20 and the two inner ship sides 4 and resulting in deformation and fracture, and improving the connection strength and connection stability of the catamaran.

[0036] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
