Dragon boat with frusta support type suspension base plate arranged in boat body with integrated inner layer and outer layer

Abstract

The invention relates to a dragon boat with frusta support type suspension base plates arranged in a boat body with integrated inner layer and outer layer, which is characterized in that the boat body comprises an integral liner, an integral outer shell and a boat board beam, the front end of the liner is provided with a boat head hanging groove, a boat channel card, caulking grooves of chairs and a drum position, the rear end of the liner is sequentially provided with a rudder position and a boat tail hanging groove, the inner walls of the both inner sides of the liner under a water line of the dragon boat are provided with base plate edges, the integral liner is arranged in the integral outer shell, the boat board beam is connected with the top parts of the integral outer shell and the integral liner to form the double-layer wall boat body with a head floating bin and a tail floating bin, the boat head hanging groove and the boat tail hanging groove are respectively articulated with a boat head and a boat tail, the frusta support type suspension base plates are distributed on the base plate edges of the liner, and both sides of the bottom center of each frusta support type suspension base plate are provided with double pedals. The dragon boat not only has reasonable design, compact structure and improved strength and rigidity, is not easy to deform, but is easy to manufacture and assemble and increases production efficiency, and the boat head and the boat tail are not easy to damage, are convenient to carry and have attractive appearance.

Description

technical field [0001] The invention belongs to dragon boat equipment, in particular to a dragon boat in which a pier type suspended seat board is arranged in a double-walled boat body of the whole inner and outer layers. Background technique [0002] At present, with the development of dragon boat culture, from traditional wooden dragon boats to current fiberglass dragon boats, there are more and more varieties and specifications; after patent retrieval, there is a "composite material" with patent number 01240664.3 "Dragon Boat" patent, it uses composite material - fiberglass to process the dragon boat body with a single wall, the same as the wooden dragon boat, and makes a mold that can process the shape of the dragon boat body with the outer dimensions of the dragon boat body - the female mold. On the inner surface of the mold, the composite material is stacked layer by layer to the thickness of the single wall required by the boat body. After curing, the mold is unloaded...

AI Technical Summary

Problems solved by technology

Apparently, this single-wall boat body made of composite materials, although it can overcome the low water absorption rate of wooden dragon boats, the boat body is heavy, the sliding speed is slow, weather resistance, poor sealing, and consumes a large amount of wood. However, since the boat body is still a single-layer boat wall, its structure is not very reasonable. To ensure that the boat body has enough rigidity to prevent the boat body from deforming, it is necessary to increase the wall thickness and increase the longitudinal upper and lower keels, especially in the The addition of a longitudinal keel and a support seat to support the seat plate in the dirty boat body not only complicates the process, but also increases the weight, especially the inner surface of the boat is already very rough, which cannot fully reveal the beautiful appearance of the dragon boat, and the position of the pedals is not suitable for ergonomics. And parts that cannot be firmly fixed such as drums, seats, rudders, etc.

In recent years, a double-walled dragon boat with its patent number ZL20051006478.3 and its manufacturing process have also appeared in the market. Its structure includes a dragon head, a boat body, a dragon tail, a channel board, and a seat , drum position, seat plate, rudder position, head floating warehouse and stern floating warehouse. The boat body, wherein the inner layer of the boat is an inner layer formed by connecting the inner shell made of composite material at the bottom of the wooden stern rafters, that is, the outer shell below the draft of the dragon boat; The boat body has improved compared with the above-mentioned single-layer wall boat body, but when assembling the inner layer of the boat, its assembly and manufacturing process is very complicated; at the same time, the channel board, seat, drum position and rudder position are all manufactured separately Installed on the dragon boat deck, it is laborious and time-consuming to assemble; in addition, each seat in the boat body is supported by a supporting bridge device, which not only has a complicated structure, but also has unsatisfactory rigidity and strength; at the same time, the connection between the dragon head and the dragon tail The method is unreasonable, making the dragon head and tail easy to be damaged
