Problems solved by technology

[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
The patent with authorized notification number CN100360378C discloses a bionic flat ship propeller, although the efficiency is high, but the structure is relatively complicated

Embodiment Construction

[0009] The present invention is illustrated in conjunction with accompanying drawing now: a kind of manpower double pushes boat, comprises hull A, left manpower device C, right manpower device D, left propeller E and right propeller F. The left manpower device C and the right manpower device D have the same structure and are symmetrically installed on the left and right sides of the longitudinal symmetry plane of the hull A. The right manpower device D comprises a power input device and a power transmission device 8, and the power input device adopts a hand crank mechanism 7, and a movable sleeve 71 is arranged at the gripper position of the hand crank mechanism 7, so as not to rotate for a long time and hurt hands. The power of the right human power device D is transmitted to the right propeller F through the power transmission device 8 . The power transmission device 8 includes a gear set 81 and a timing belt transmission 82 . The gear set 81 includes a driving gear and a d...

Abstract

The invention relates to a man-powered double-propelling boat and belongs to the field of marine technology. The man-powered double-propelling boat comprises a boat body, a left man-powered device, a right man-powered device, a left propeller and a right propeller. The left man-powered device and the right man-powered device are symmetrically installed in structure. The right man-powered device comprises a power input device and a power transmitting device. Power of the right man-powered device is transmitted to the right propeller through the power transmitting device. The power transmitting device comprises a gear set, and further comprises a synchronous belt transmitting device or a chain transmitting device. The left propeller and the right propeller are of the same structure and are symmetrically installed on the left side and the right side of the boat body. The right propeller comprises a main shaft, a rotary disc, an annular flat plate blade, a traction rod, a positioning rod and a shell. The left propeller and the right propeller are connected with the left man-powered device and the right man-powered device respectively. The left man-powered device and the right man-powered device are independently operated. The movement effects similar to rapid opening and opposite flapping of insects can be generated through work of the left propeller and the right propeller. The boat is small in energy loss, high in efficiency and flexible, and the blades are easy to manufacture.

Description

technical field [0001] A human-powered double-push small boat belongs to the technical field of ships, and in particular relates to a human-powered 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. Contents of the invention [0003] The purpose of the invention is to overcome the deficiencies of traditional ship technology, and invent a labor-saving manpower double push boat with higher efficiency. [0004] The utility model relates to a manpower double-push small boat, which comprises a hu...
