Dragon boat with double-walled hull and its manufacturing process

Abstract

The invention relates to a double-wall dragon boat and its facture. It is characterized in that connect a double-wall boat body between the dragon head and the tail, the double-wall has the external layer of the outside shell made of the compound material, the inner side of the outside shell above the floating line is adhered the inner layer of the wood board and forms the upper part of the boat, the outside shell below the floating line connects the inner layer of the inside shell forms the lower part of the boat, the two sides of the shell top set the longitudinal dragon bone, and the top side face opposite the side bone is distributed with the bearing bridge equipment composed of the bearing board, the bridge, the support base and the bolts, the boat bottom below the bearing board has two kicks, the body has front and back floating cabs. The invention has tight structure, proper design and strong rigidity.

Description

technical field [0001] The invention relates to a double-walled dragon boat of dragon boat equipment and a manufacturing process thereof. 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. The seat plates are evenly distributed between the head and the tail with the sam...

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.
