Problems solved by technology

[0003] 1. Existing still-water racing boats and oars are designed with flat or smooth surfaces, and there is a singleness in the design and no diversity;
[0004] 2. The existing still water racing boats and oars are designed with solid or hollow design, which has poor shock absorption, because the boats and oars in the still water competition are driven by periodic oar force at all times. Every paddle undergoes a deceleration process. In addition to the motion in the forward direction, the paddle is also affected by the impact of the non-advance direction, such as wind, waves, shaking, turbulence and other motion fluctuations. The resistance caused by water resistance friction accounts for about 70% of the total resistance. % to 80%, during high-speed movement, frictional resistance accounts for about 40% of the total resistance, resulting in non-kinetic energy loss during rowing

Abstract

The invention discloses a special boat and a paddle for flat-water racing. The boat comprises a boat body, the paddle comprises a paddle body, each of the boat body and a blade of the paddle body comprises a middle supporting layer, shock absorption layers, carbon fiber layers and anti-drag layers, wherein the middle supporting layer is in a three-dimensional interlocked concave honeycomb structure and externally coated with the shock absorption layers in porous foam board structures, the shock absorption layers are externally provided with the carbon fiber layers which are externally providedwith anti-drag layers, and the carbon fiber layers on the front surface and the back surface of the blade are both provided with one or more water parting lines protruding in V shapes. Resistance ofthe boat and the paddle in movement can be sharply reduced, water resistance friction is reduced, and nondynamic energy loss is reduced as far as possible.

Description

technical field [0001] The invention belongs to the technical field of special equipment for still water racing competitions, and in particular relates to a new type of special boat and paddle for still water competitions. Background technique [0002] The existing still water racing boats and paddles including dragon boats, rowing boats, kayaks and other still water racing competitions are not enough in design and the problems are as follows: [0003] 1. Existing still-water racing boats and oars are designed with flat or smooth surfaces, and there is a singleness in the design and no diversity; [0004] 2. The existing still water racing boats and oars are designed with solid or hollow design, which has poor shock absorption, because the boats and oars in the still water competition are driven by periodic oar force at all times. Every paddle undergoes a deceleration process. In addition to the motion in the forward direction, the paddle is also affected by the impact of t...
