Multi-person manpower boat

Abstract

The invention provides a multi-person manpower boat and belongs to the technical field of ships. The boat comprises a boat body and multiple groups of propelling devices which are the same in structure. Each group of propelling devices comprises a left manpower device, a right manpower device, a left propeller and a right propeller. The left manpower devices and the right manpower devices are symmetrically installed in structure. Each right manpower device comprises a power input device and a power transfer device. Each power transfer device comprises a gear set and further comprises a synchronous belt transmission device or a chain transmission device. The left propellers and the right propellers are the same in structure and symmetrically arranged on the left side and the right side of the boat body. Each right propeller comprises a main shaft, a rotating disc, an annular panel blade, a traction rod, a positioning rod and a shell. The left propellers and the right propellers are connected with the left manpower devices and the right manpower devices respectively. The left manpower devices and the right manpower devices are operated separately. The boat is high in efficiency, maneuvering, flexible, convenient to operate, steady and applicable to sports competition, leisure amusement and transportation.

Description

technical field [0001] The utility model relates to a multi-person human boat, which belongs to the technical field of ships, and in particular relates to a human boat. Background technique [0002] The propellers of traditional ships mostly use propellers. Although the drive is convenient, the efficiency is low. Large, the water resistance of the blade is large after entering the water and before the water exits, and the thrust generated is very small, the energy loss is large, the efficiency is low, and the noise is large. Authorized notification number is the patent of CN100360378C, discloses a kind of bionic flat ship propeller, although efficiency is higher, structure is more complicated. Traditional human-powered boats are hand-operated. Although simple, the efficiency is not high, and certain skills are required to control them. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of traditional ship technology, i...
