AI Technical Summary

Technical Problem

Existing vessels require continuous human effort when operating against the current or in turbulent waters, leading to rapid physical exhaustion and easy fatigue.

Method used

Design a water bicycle that simulates human rowing through a mechanical transmission system. The pedals drive a chain and gear mechanism, which in turn drives a transmission gear set and an adjustable rod to achieve the mechanical swinging of the oars, thus reducing the need for manual labor.

Benefits of technology

It improves rowing efficiency, reduces manpower consumption, allows boats to travel farther in a shorter time, provides a stable rowing experience, and increases tourism appeal and enjoyment.

Abstract

This invention discloses a water bicycle, relating to the field of water sports equipment technology. It includes a buoyancy platform main frame, a steering mechanism at the top front end of the main frame, a seat fixedly connected to the middle area of ​​the main frame, a drive chain gear mechanism below the seat, and a rudder mechanism at the other end of the main frame. The main frame is fixedly connected to a steering bracket, a steering rod rotatably connected to the steering bracket, and a rudder plate fixedly connected below the steering rod. By sitting on the seat and stepping on the drive chain gear mechanism, the user indirectly drives a first adjustable rod and an outer fixed inner arc bearing to swing via an auxiliary rod. The outer fixed inner arc bearing pushes the rudder to swing left and right on a universal joint, simulating human rowing. By replacing human rowing with mechanical transmission, the efficiency of rowing can be greatly improved, and human labor consumption reduced.
