Problems solved by technology

[0003] Background technology: the traditional scull is a scull that people (by pushing and pulling) shake to both sides. It is only suitable for use on slightly larger ships. Nowadays, slightly larger ships basically adopt the mode of propulsion by motorized propellers, while small boats It is not suitable to use the scull, because the way of scull propulsion will make the boat run to both sides, and the way of rowing with oars is actually not very efficient, because the way of rowing is intermittent, not continuous

Embodiment 1

[0010] Embodiment 1 refers to 1, 2, and 3 bionic fishtail sculls, including a fixed frame 1, a crowbar frame 2, a handle 3, a lifting rod 4, a tail blade connector 5, and a fishtail blade 6. The fixed frame 1 is fixed at the stern, and the pry bar The rod frame 2 is connected to the fixed frame 1 through a shaft and a bearing, the handle 3 is connected to the crowbar frame 2, the top of the lifting rod 4 is connected to one end of the crowing rod frame 2, and the tail leaf connecting piece 5 with the up and down backing is fixed on the bottom of the lifting rod 4. At the top, the fishtail blade 6 is connected to the tail blade connector 5 through a copper ring and a shaft. When the handle 3 is moved upwards, one end of the crowbar frame 2 will move down with the lifting rod 4. At this time, due to the resistance of the water and the blocking of the upper backing, the fishtail leaf 6 forms an upward angle with the horizontal direction, and makes the fishtail The downward thrust...

Abstract

The invention relates to a manpower ship propeller, and particularly relates to a bionic fishtail oar which can effectively push a boat to move forwards through up-and-down shaking. The bionic fishtail oar can be installed at the stern or the prow. The bionic fishtail oar comprises a fixing frame, a crow bar frame, a handle, a lifting rod, a tail blade connecting piece and a fishtail blade, wherein the fixing frame is used for being fixed to the stern or the prow, and the crow bar frame is connected with the fixing frame through a shaft and a bearing and can change the angle with a hull; the crow bar frame is a parallelogram frame with a changeable angle, bearings are embedded in four connection points of the crow bar frame, one side of the crow bar frame is connected with the handle, andthe other side of the crow bar frame can be in linkage with the lifting rod to perform vertical lifting motion; the fishtail blade can form a downward or upward angle along with ascending or descending of the lifting rod, and forward thrust is generated. Compared with the traditional oar and paddle, the bionic fishtail oar has the characteristic that the boat is enabled to be more stable in driving, higher in speed and more convenient to operate being applied to the boat.

Description

technical field [0001] The invention relates to a propeller for a human-powered ship, in particular to a bionic fishtail oar which can effectively propel a small boat forward by using up and down shaking. [0002] technical background [0003] Background technology: the traditional scull is a scull that people (by pushing and pulling) shake to both sides. It is only suitable for use on slightly larger ships. Nowadays, slightly larger ships basically adopt the mode of propulsion by motorized propellers, while small boats It is not suitable to use sculls, because the way of propulsion by sculls will make the boat run to both sides, and the way of rowing with oars is actually not very efficient, because the way of rowing is intermittent, not continuous. Contents of the invention [0004] Summary of the invention: The object of the present invention is to imitate the swimming method of whales and dolphins with the tail swinging up and down, and provide a bionic fishtail oar whi...
